Anonymous users2024-02-06The eight comprehensive protection access of the belt conveyor is equipped with an intelligent temperature sensor, and the temperature can be set through the man-machine interface; When the switch type temperature sensor is connected, the roller and bearing of the belt conveyor or the ambient temperature are monitored, and the temperature setting value is divided into three gears, and when the temperature of the monitoring point is higher than the setting value, the monitoring device can automatically cut off the power supply of the belt conveyor, so as to achieve over-temperature protection. The setting error value of over-temperature protection is less than 5, through the matching of intelligent or ordinary multiple deviation sensors, the deviation of the belt conveyor is monitored, when the belt deviation of the belt conveyor, after 20 40s delay, the monitoring device cuts off the power supply of the belt conveyor, realizes the deviation protection, and the deviation sensor is not limited to the number of installations.
Equipped with an independent RFMH thermal over-temperature automatic sprinkler device, China Coal can automatically sprinkle water for over-temperature and fire accidents, which can effectively prevent the occurrence and development of accidents. The protection temperature of the thermal over-temperature automatic sprinkler can be selected between 35 and 70, and the factory is generally selected at 50 2. In the case of coal stacking, the angle of the coal level sensor is offset, the contact is closed ALI11, and the monitoring device cuts off the power supply of the belt conveyor, so as to realize the coal stacking protection, and the coal stacking protection action is delayed by 1-3s.
When the belt conveyor is used for chain machine control, after the synchronous sensor is matched, the scraper can be tilted more than 15° after the chain is broken for protection. When a single unit is used: this device is placed in the manual control mode, and its starting and parking are controlled by the starting and parking buttons on this tabletop panel, and this device will send out the language signal of "the first belt is about to start, pay attention to safety", after a delay of 8 2s, the belt starts to run.
When you need to stop, press the stop button once.

2. Eight protection devices for belt conveyor.
3. What are the eight major protection devices of the belt conveyor?
4. What are the brands of the eight major protection devices of the belt conveyor?
1.Overload protection: An overload protection device installed to prevent the main power supply line from overheating and damage to the protector due to overload.
2.Overcurrent protection: When the current exceeds the set current, the device will automatically power off to protect the device.
3.Two-way rope switch protection: It is a kind of protection device for the on-site emergency shutdown of the belt conveyor.
4.Speed switch protection: When an electric shock occurs, the neutral point is offset to generate a voltage to the ground, so as to cut off the power supply.
5.Longitudinal tear protection: Using the principle of electromagnetic induction, the receiver receives the electromagnetic pulse signal generated by the generator through the sensing coil.
6.Two-stage deviation switch protection: according to the degree of deviation of the belt, it can realize automatic alarm and shutdown.
7.Coal flow signal protection: It can provide alarm signals such as belt coal flow, coal breakage, coal blockage, and chain breakage.
8.Coal plugging switch protection: use the change of the contact opening and closing in the coal plugging switch to judge the working condition of the protection equipment, and take timely measures to achieve the purpose of safety protection.

Anonymous users2024-02-02What are the potential safety hazards of the belt conveyor, please describe it clearly.
Hello dear<>
Answer: The belt conveyor has three dangerous slag points under the late journey. First, the belt conveyor head, tail and guide roller must be placed with a protective fence and the protective fence must be sensitive and reliable. Second, it is forbidden to go up to people and other items when the belt is running.
The belt transport driver must concentrate on avoiding the slippage of the belt due to the material during the normal operation, such as the transfer. Third, when the belt is running normally, it is strictly forbidden for post workers to clean the running parts to avoid safety accidents.

Anonymous users2024-02-01The transmission ratio accuracy of the belt drive is worse than that of the gear meshing drive, but when it is overloaded, the belt slips, which plays an overload protection role. The belt transmission mechanism has stable transmission, low noise, simple structure and easy maintenance. Therefore, belt transmission mechanism is widely used in mechanical transmission.
However, because the belt is prone to electrostatic discharge after friction, it cannot be used in places where it is prone to combustion or **.
The dangerous part of the belt ridge bucket cong transmission mechanism is that the cherry blossom and the belt enter the pulley at the belt joint, so it should be protected.
The distance between the belt guard and the belt should not be less than 50mm, and the design should be reasonable and should not affect the operation of the machine. Generally, the transmission mechanism is less than 2m from the ground, and a protective cover should be provided. However, in the following 3 cases, it should be protected even if it is more than 2 meters:
The distance between the pulleys is more than 3m; The width of the belt is more than 15cm; The speed of belt rotation is more than 9m min. In this way, if the belt breaks, it will not fall and hurt people.
The joints of the belt must be firm and reliable. When installing the belt, it should be tightened appropriately. The protection of the belt transmission mechanism can be the method of covering the belt completely, or the protection of the protective railing.
