Adjustment method of the supporting roller of the drum dryer

Summary. Hello, I'm glad to answer for you. The adjustment of the supporting wheel of the drum dryer is mainly to ensure the stability and safety of the dryer during normal operation.

The following are some commonly used methods for adjusting the supporting rollers: 1. The position of the supporting roller: First of all, you need to confirm whether the position of the supporting roller is correct, and each supporting roller should be evenly distributed on the rotating drum.

2. Height adjustment: The adjustment of the height of the supporting roller is usually achieved by adding or subtracting bolts, generally speaking, if the supporting roller is too high, the machine will be unstable; If the carrier roller is too low, it will increase friction with other components and may damage the dryer. 3. Orientation adjustment:

The orientation adjustment ensures that the carrier falls in the correct position and rotates smoothly. When making adjustments, it is necessary to check that the position of the carrier axle is perpendicular to the axis of the bowl and that the orientation of each carrier roller is the same.

Hello, I'm glad to answer for you. The adjustment of the supporting roller of the drum dryer is mainly to ensure the stability and safety of the dryer during normal operation. Here are some commonly used ways to adjust the rollers:

1. Carrier Position Limb Sail: First of all, you need to confirm whether the position of the supporting roller is correct, and each supporting roller should be evenly distributed on the drum. 2. Height adjustment:

The adjustment of the height of the carrier roller is usually achieved by adding or subtracting bolts, generally speaking, if the carrier roller is too high, the machine will be unstable; If the carrier roller is too low, it will increase friction with other components, and it may damage the dryer. 3. Azimuth adjustment: Azimuth adjustment can ensure that the supporting roller falls in the correct position, so that it rotates very smoothly.

When making adjustments, it is necessary to check that the position of the carrier axle is perpendicular to the axis of the bowl and that the orientation of each carrier roller is the same.

Please note that the operation steps and detailed guidance provided by the dryer manufacturer should be followed when adjusting the rubber and burying the rubber of the feed roller to ensure the accuracy and safety of the adjustment. [hug not contained].

The installation steps of the dryer supporting roller are as follows:1First, move the dryer to the location where the carrier needs to be installed and locate the location where the carrier needs to be installed.

2.Make a screw hole in the selected position and fix the base of the roller with screws. Make sure the screws are secure to tease the holes so they don't loosen.

3.Install the carrier roller on the base and adjust as needed. 4.

Check that the supporting rollers are installed firmly and evenly to ensure that the dryer moves smoothly and does not wobble. The above are the installation steps of the general dryer supporting wheel, but due to the different models of different brands and models of dryers and supporting rollers, the installation should also be combined with the specific Ancha finger bridge installation instructions to operate.

Dear, I am glad to answer for you, the installation steps of the dryer supporting wheel are as follows:1Tilt the dryer and secure it to the ground so that you can easily install the carrier rollers in front of the reed.

2.Remove the protective cover at the bottom of the dryer and tremble. 3.

Insert the carrier roller into the carrier groove at the bottom of the dryer, making sure the carrier roller is exactly aligned with the groove. 4.Screw the carrier roller tightly to ensure that the carrier is securely mounted on the dryer.

5.Reinstall the protective cover on the bottom of the dryer strap. 6.

Return the dryer to a vertical position. 7.Test that the dryer is able to rotate properly and that the carrier rollers are properly installed.

Because when the cylinder is bent in the operation of the equipment, every rotation of the dryer, the inclination of the loose wheel belt changes relative to the supporting roller, in this case, it is impossible to ensure the uniform contact between the wheel belt and the supporting roller, and the pressure on the surface of the wheel belt and the supporting roller is greatly increased in the local area, resulting in uneven surface wear and deformation, producing a concave platform, the edge produces a boss, and the supporting roller is frequently damaged.

The structural design is unreasonable: due to the unreasonable structural design, the cylinder is placed on the supporting roller at an inclined certain angle, the structure and size of the large wheel belt before and after the cylinder are different, the area of contact between the rear supporting roller and the wheel belt is narrower, and the cylinder is inclined at a certain angle, the pressure on the rear supporting roller is larger, and after working for a long time, the supporting wheel is easy to deform or wear after preparing the ridge.

Improper operation of the operator: when the equipment is drying the material, it does not pay attention to the up and down movement of the cylinder, or the adjustment method of the front and rear supporting rollers, resulting in a huge change in the force of the rear supporting roller in the whole working process, resulting in serious wear of the rear supporting roller.

The maintenance method of the equipment is incorrect: when the equipment is used for a long time, due to the action of high-temperature air flow for a long time, the wheel belt and backing plate on the cylinder will be seriously worn and deformed, and the wheel belt may become oval again, then the pressure on the supporting roller will change, and eventually the supporting roller will be seriously worn.

1. Reasons for the structural design of the equipment. The rear supporting wheel is between the two stop wheels, in order to make the roller and the supporting roller evenly wear on the full width, and make the transmission of the large and small gears good before meshing, and at the same time to ensure that the sealing devices at the front and rear ends of the cylinder do not lose the sealing effect, so the up and down momentum of the cylinder is about 20mm. The front and rear rollers of the dryer have the same structure and size, with a width of 160ram, but the structure and size of the front and rear rollers are slightly different (mainly the rear roller belt with a taper to make contact with the stop wheel).

The width of the front roll is 120mm, and the contact width between the rear roll and the supporting roller is 100mm (the width of the contact with the roll pad is the same as the front roll, which is also 120mm, so that the size of the front and rear roll pads is the same, so as to facilitate the storage of accessories). In this way, for a properly installed rear carrier, there will be 20 ram in width where the carrier will not be able to contact the roller. Of course, due to processing, installation and adjustment, as well as the wear and tear of the roller and the upper and lower stops during operation, the value of the real Li punching gap may be smaller, but from the design point of view, it is completely impossible to ensure that the rear supporting roller and the full width of the roller can be contacted.

For the front supporting roller, there are 10mm in the front and back of its width, which is also inaccessible on the surface, but because the cylinder has a thermal elongation, according to the design value of 8 3mm, in this way, the front supporting roller can be in contact with the full width of the roller. Obviously, due to design factors, the roller cannot be in contact with the full width of the roller, and due to the wear of the roller during operation, the part that does not come into contact will be higher than the worn part, resulting in the saddle shape of the roller.

2. Improper maintenance during use, artificially make the simplified body always in the upward state of slag (such as some factories, in order to ensure that the sealing device at the upper end of the simplified body is in contact with the phenomenon of smoke, so that the simplified body is always in the upward position) or downward channeling, which will also cause the supporting roller to be ground into a saddle shape or step shape, and once the saddle shape or step shape is formed, it is more difficult to cross the steps.

3. If you do not pay attention to the movement of the simplified body, or the improper adjustment of the supporting wheel, it will also make the simplified body unable to move up and down normally, so that the supporting roller and the roller will be in contact with the roll in a small area, resulting in the phenomenon of saddle shape or steps.

4 Improper maintenance. When the roller and backing plate stoppers are worn to a certain value, measures cannot be taken to adjust the position in time or the repositioning position is incorrect, which will also make the supporting roller form a saddle shape or step shape.

5. When drying materials, the temperature is generally above 500 C, and the simplified body is heated and bent and deformed, resulting in uneven stress on the supporting roller, resulting in uneven wear of the roller and the supporting roller, and also making the supporting roller form a saddle shape or step shape.

Analysis of the causes of serious wear on the surface of the supporting roller of the dryer The supporting device is composed of the supporting roller, the supporting roller shaft and the bearing. The supporting roller is installed in this way, which can ensure the stability of the cylinder and be squeezed by the supporting roller, and the supporting roller shaft is parallel to the center line of the dryer, which can ensure that the wheel belt is in uniform contact with the surface of the supporting roller. The carrier shaft and the cold dryer axis are parallel.

However, because when the dryer is bent in the operation of the cylinder, every turn of the dryer, the tilt of the loose wheel belt changes relative to the key cracking wheel, in this situation, it is impossible to ensure the uniform contact between the wheel belt and the supporting wheel, and the pressure on the surface of the wheel belt and the supporting roller is greatly increased in the local area, resulting in uneven surface wear and deformation, resulting in a concave platform, a boss at the edge, and frequent bearing damage.
