Description

Technical Field

[0001] This utility model relates to the field of dust removal technology, specifically to an automated dust removal device for conveyor belts. Background Technology

[0002] In the process of thermal power generation, the transportation of coal is inevitably involved. During the return journey of the conveyor belt transporting coal, the inner surface of the conveyor belt passes under the slag cooler, where a large amount of dust falls onto the inner surface of the conveyor belt. Furthermore, the height difference created by the movement of the conveyor belt at its rollers leads to the escape and deposition of dust. Dust escape causes environmental pollution and affects worker health, while dust deposition can cause conveyor belt jamming and misalignment, affecting the conveyor belt's service life. Current conveyor belt dust removal equipment typically discharges dust directly into the outside air and only cleans the outer surface of the conveyor belt.

[0003] An existing utility model patent with application number CN202022944189.3, entitled "A Concrete Building Material Conveying Structure with Dust-proof Function," discloses a concrete building material conveying structure with dust-proof function. It includes a fixed frame, a support column installed below the fixed frame, a conveyor belt arranged inside the fixed frame, a motor installed on one side of the fixed frame, working plates on both sides of the fixed frame, grooves on the inner surface of the working plates, dust suction ports on the inner side of the grooves, a protective plate installed on the outer side of the working plates, connecting plates on both sides of the protective plate, a fan fixedly installed on the inner surface of the connecting plate, a dust suction pipe above the fan, and a collection chamber at one end of the dust suction pipe. While the technical solution disclosed in this utility model patent can effectively prevent dust from escaping during conveyor belt operation, it suffers from the technical problem of not being able to clean dust that may accumulate inside the conveyor belt. Dust accumulation inside the conveyor belt to a certain extent will inevitably affect its operation. Utility Model Content

[0017] The present invention will now be described in conjunction with the accompanying drawings.

[0018] Figure 1This utility model discloses a conveyor belt dust removal device, including a dust removal unit, a conveyor belt including rollers, and a control module 1. The dust removal unit includes a dust collection passage composed of a blowing module 2, a dust cover 7, and a suction module 3. The dust cover 7 covers the end of the conveyor belt away from the material outlet, thereby removing dust from the conveyor belt without affecting the material transport section.

[0020] Furthermore, the purging module 2 also includes a jetting device 22, a first switching valve 23, a first flow meter 24, a first pressure gauge 25, and a first thickness sensor 26. The jetting device 22 is located outside the dust cover 7, and its outlet is connected to the air vent at the bottom of the dust cover 7 via the first switching valve 23, ensuring that dust removal and normal operation of the conveyor belt can be carried out simultaneously. The first flow meter 24 and the first pressure gauge 25 are located on the pipe connecting the air vent at the bottom of the dust cover 7 and the first switching valve 23. The first thickness sensor 26 is located on the dust cover 7. The first flow meter 24, the first pressure gauge 25, and the first thickness sensor 26 are respectively connected to the control module 1 via circuits, and the control module 1 controls the jetting of the purging module 2.

[0021] Furthermore, the blowing device 22 adopts an electric pulse blowing device, which improves the efficiency of blowing dust inside the dust cover 7.

[0022] Furthermore, the cleaning roller 21 includes a central shaft and a brush roller. The brush roller rotates around the central shaft, and the two ends of the central shaft are respectively installed on both sides of the dust cover 7, so that the cleaning roller 21 can rotate inside the dust cover 7, and the outer surface of the brush roller simultaneously contacts the inner surface of the conveyor belt and the roller, thereby cleaning the inner surface of the conveyor belt and the roller.

[0023] Furthermore, it also includes a flow stabilization module 4, a gas-dust separation module 5, and a dust collection module 6 connected in sequence. The air inlet of the flow stabilization module 4 is connected to the dust collection passage. The dust-generating gas sucked in by the suction module 3 is buffered by the flow stabilization module 4 before entering the gas-dust separation module 5 for gas-solid separation. Finally, the separated dust enters the dust collection module 6 for collection and processing.

[0024] Furthermore, the flow stabilization module 4 includes a third pressure gauge 41, a third flow meter 42, a buffer device 43, and a first check valve 44 connected in sequence. The buffer device 43 is connected to the dust collection passage, and the third pressure gauge 41 and the third flow meter 42 are installed between the connecting pipelines of the two. The third pressure gauge 41, the third flow meter 42, the buffer device, and the first check valve 44 are respectively connected to the control module 1 through circuits. The suction device 34 is connected to the gas-dust separation module 5 through the first check valve 44. The first check valve 44 can prevent backflow of gas and dust during gas-dust separation. The control module 1 controls the state of the buffer device 43 and the first check valve 44 according to the parameters returned by the third pressure gauge 41 and the third flow meter 42.

[0025] Furthermore, the gas-dust separation module 5 includes a dust collector 51 and a second check valve 52. The dust collector 51 and the second check valve 52 are connected to the control module 1 via a circuit. The dust collector 51 is connected to the suction device 34 via a first check valve 44.

The top of the ash tank 62 is connected to the dust collection port of the dust collector 51 via a pipeline. The second thickness sensor 63 is installed inside the ash tank 62. The control module 1 controls the gas-solid separation process in the exhaust tower 61 based on the thickness parameter of the dust deposited in the exhaust tower 61 transmitted back by the second thickness sensor 63, and prevents the gas in the exhaust tower 61 from flowing back into the dust collector 51 by controlling the opening and closing of the second check valve 52.

[0027] The conveyor belt dust removal device of this utility model starts operation after being installed in place relative to the target conveyor belt. After the power is turned on, the sweeping roller of the cleaning roller 21 rotates around the central axis on the dust cover 207 to clean the inner side of the conveyor belt and the roller. At the same time, the control module 1 controls the operation of the blowing device 22 and the opening of the first switch valve 23 to perform ultra-low pressure blowing on the inner side of the running conveyor belt and its roller. Meanwhile, the first thickness sensor 26 monitors in real time and transmits the dust accumulation thickness back to the control module 1. The control module 1 dynamically adjusts the pulse frequency of the blowing device 22. Then, the control module 1 controls the suction device 34 to suck up the dust and opens the second switch valve 31. The dust blown up in the dust cover 7 is sucked into the suction device 34 and enters the buffer device 43 for flow stabilization. During this process, the second flow meter 32 and the second pressure gauge 3 are used. The third pressure gauge 3 and the third pressure gauge 41 return the parameters to the control module 1 in real time. The control module 1 then dynamically adjusts the operating power of the suction device 34 to balance the gas flow rate and pressure in the entire device, so that the gas and dust can flow smoothly into the dust collector 51. Subsequently, the dust collector 51 performs gas-solid separation. The separated dust enters the ash tank 62 for storage, and the gas enters the exhaust tower 61 and is discharged. At the same time, a second check valve 52 is provided to prevent the gas in the exhaust tower 61 from flowing back into the dust collector 51 when the gas pressure is unstable. A second thickness sensor 63 is also provided to detect the amount of dust stored in the ash tank 63. When the storage amount reaches the threshold, the second thickness sensor 63 sends a signal to the upper system, and the staff transfers the dust stored in the ash tank 63.

[0028] Compared with existing technologies, the conveyor belt dust removal device proposed in this utility model has a blowing module and a suction module at one end of the conveyor belt, as well as a corresponding flow stabilization module and a dust collection module. This enables the cleaning of the conveyor belt while reducing dust. The control module controls the above modules as a whole based on the parameters returned by the sensors, ensuring the stability of the gas flow rate and air pressure in the device. This solves the technical problem that existing conveyor belt dust removal devices cannot clean the dust deposited on the inside of the conveyor belt.
