3. Introduction to the control mode of coal conveying system.

Coal conveying system control mode (automatic, manual, local control mode).

1. Automatic control mode.

1) All operations in automatic mode can be carried out through the PLC computer interface, and the coal conveying personnel on duty can operate in the PLC computer interface according to the process requirements. There is a complete flow chart of coal loading equipment on the computer, and there is an effective signal for program selection on the computer. When the plough is fully in place, a signal is sent after 20 seconds to allow starting.

The selected belt starts each equipment according to the direction of the reverse coal flow, and the alarm should sound for 20 seconds before each belt starts, and the on-site buzzer stops sound after the belt starts. When the program is shut down, it should be stopped one by one according to the predetermined delay along the coal flow.

2) In operation, when a major accident occurs in any equipment, the wire pulling action and the re-running deviation and slippage lasting 2 seconds should be immediately connected to the equipment against the direction of the coal flow, but the coal crusher should be delayed in addition to its own accident. When the emergency shutdown is pressed, the running equipment will be shut down immediately, and only the coal crusher will be stopped for a delayed time. The delay should be up to 30min.

Summary. A: The maximum amount of material that can be put in the coal conveying belt depends on the width and length of the belt and the size of the material.

Generally speaking, the width of the coal conveying belt is generally between 500mm-1200mm, and the length is generally between 10m-50m, and the size of the material depends on the specific type of material. Therefore, it is not possible to give an exact number of how much material can be put in the coal conveying belt. To solve this problem, it is first necessary to determine the width and length of the coal conveying belt, as well as the size of the material.

Then, based on the width and length of the coal conveyor belt, the amount of material that can be placed is calculated. Finally, based on the size of the item, calculate the maximum amount of material that can be placed. In addition, when using the coal conveying belt, it is also necessary to pay attention to safety issues to ensure the safe use of the coal conveying belt to avoid accidents.

Answer: The maximum amount of material that can be put in the coal conveying belt depends on the width and length of the belt and the size of the material. Generally speaking, the width of the coal conveying belt is generally between 500mm-1200mm, and the length is generally between 10m-50m, and the size of the material depends on the specific type of material.

Therefore, it is not possible to give an exact number of how much material can be put in the coal conveying belt. To solve this problem, we must first determine the width and length of the coal conveying belt to meet the size of the material. Then, based on the width and length of the coal conveyor belt, the amount of material that can be placed is calculated.

Finally, based on the size of the item, calculate the maximum amount of material that can be placed. In addition, when using the coal conveying belt, it is also necessary to pay attention to safety issues to ensure the safe use of the coal conveying belt to avoid accidents.

Can you tell us more about that?

In response to this problem, the maximum amount of material that can be put in the coal conveying belt depends on the width, length and size of the coal conveying belt. Generally speaking, the width of the coal conveying belt is generally between 500mm-2000mm, and the length is generally between 10m-100m, and the size of the material depends on the specific type of material. For example, if the width of the coal conveying belt is 1000mm, the length is 50m, and the size of the material is 50mm, then the coal conveying belt can be placed with a maximum of 50*50*50 1000=125kg of material.

In addition, the width and length of the coal conveying belt will also affect how much material can be placed at most, the larger the width, the more materials can be placed; The longer the length, the more material can be placed. In addition, the material of the coal conveying belt will also affect how much material can be placed at most, generally speaking, the material of the coal conveying belt is rubber, plastic, metal, etc., and the amount of material that can be placed in the coal conveying belt of different materials is also different. In general, the maximum amount of material that can be put in the coal conveying belt depends on the width, length and size of the material of the coal conveying belt, as well as the material of the coal conveying belt and other factors.

What safety measures should be listed on the work ticket for the maintenance of the replacement roller of the coal conveying belt?

Classification of safety sources According to the characteristics of the belt conveyor in the concentrator, we divide the safety source of the belt conveyor into 7 categories according to the structural characteristics of the belt conveyor, namely: conveyor belt, driving device, electric drum, transmission, redirection, tensioning roller vertical cylinder, idler, cavity disturbance bending cleaner, unloading device, etc. 3. The general provisions of safety precautions strictly prohibit the load start of the belt conveyor, such as in operation, when the machine must be shut down due to power failure or other reasons, the load on the belt conveyor must be cleared before it can be started again.

It is strictly forbidden to cross the belt, and the crossing platform must be set up; When the belt is running, it is strictly forbidden to hit with hands or objects, adjust the roller, sort out the cleaner, remove the drum rolling area ore and remove the funnel deposit, when it must be handled, it is necessary to stop the machine and have a special person to take care of it, and strictly implement the delisting system of Wu Stuffy Electric Hanging, especially remind that when clearing the funnel deposit, there must be a person outside to monitor, and when the height exceeds 2 meters or the operation is inconvenient, the operator should fasten the safety belt. When removing the belt or installing a new belt, a special tool should be set up to clamp one end of the belt, slowly loosen or lift, and when the oblique belt is replaced, it is strictly forbidden to stand at the bottom; When hoisting is required for maintenance, it is necessary to strictly abide by the safety of aerial work and ensure the safety and reliability of hoisting equipment; When the overhaul is completed, the personnel on the belt and close to the belt conveyor should ensure that all of them leave before they can be tested; There should be a special person to command and operate during the test; If there is an abnormal situation in the test, it is necessary to stop the machine to deal with it, and after the treatment is completed, it can be tested again, and in the test, the ore should be given from less to more, and the ore should be evenly fed. All participants are required to wear labor protection equipment.

4. Safety precautions: The replacement of belts, joint bonding, surface glue layer treatment, edge defect treatment, and the whole or partial replacement of belts according to different conditions and requirements, before the replacement, the mobile management office will make a complete set of safe and feasible replacement measures and specific terms. Joint bonding is not a special emergency, we require that the bonding of all joints should be carried out by vulcanization bonding, and the specific vulcanization methods and requirements will be issued at the same time as an annex to this matter; The treatment of the top adhesive layering, the surface adhesive layer treatment and the edge defect treatment used in the treatment of edge defects shall be carried out in the shutdown state, and the power outage and delisting system shall be carried out in strict accordance with the items. The personnel involved in the maintenance shall wear labor protection equipment as required and carry out the operation as required; When you're done, press .
