Abstract
Description
Technical Field
[0001] This utility model relates to the field of pulse dust collector technology, and in particular to a cylindrical pulse dust collector. Background Technology
[0002] A dust collector is a device that separates dust from flue gas. A pulse dust collector is a new type of high-efficiency pulse dust collector that is improved on the basis of a bag dust collector. It combines the advantages of various pulse jet dust collectors with compartment reverse air and overcomes the disadvantages of insufficient compartment cleaning intensity and uneven air distribution, thus expanding its application range.
[0003] A search revealed Chinese patent CN212017102U, which discloses a cylindrical pulse dust collector. While this patent can improve the efficiency of pulse dust collection, the dust inside the collector falls and accumulates at the bottom, requiring staff to open the bottom valve to allow the dust to flow out. However, in scenarios with large-scale use of pulse dust collectors, frequent manual cleaning is necessary, wasting manpower and making monitoring difficult. Failure to clean in a timely manner can easily lead to blockage of the collection hopper. Therefore, to better improve the performance of pulse dust collectors and to advance industry technology and enhance core technological competitiveness, this application proposes a new implementation scheme that differs from the existing cylindrical pulse dust collector structure and application method. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A cylindrical pulse dust collector includes a shell and a transport trolley. A top cover is connected to the top of the shell via a flange, and a collection hopper is connected to the bottom of the shell via a flange. A first retaining plate is fixedly connected to the bottom of the collection hopper. A solenoid valve is installed at the bottom of the collection hopper. A bracket is fixedly connected to the outer circumference of the collection hopper, and two grooves are provided on the inner bottom wall of the bracket. Rollers of the transport trolley roll within these grooves. Multiple pressure sensors and two warning lights are fixedly connected to the top of the transport trolley. A second retaining plate is located at the bottom of the first retaining plate. A clamp is fitted around the outer circumference of the second retaining plate and the first retaining plate. A top plate is fixedly connected to the bottom of the second retaining plate, and a corrugated pipe is fixed to the bottom of the top plate. A bottom plate is fixed to the bottom of the corrugated pipe, and the bottom plate is placed on top of the multiple pressure sensors.
[0007] Furthermore, a plurality of guide shafts are fixedly connected to the top of the base plate, with the top ends of the guide shafts passing through the top plate.
[0008] Furthermore, an air supply bag is provided on one side of the outer casing. Multiple electromagnetic pulse valves are sealed and inserted into the top of the air supply bag, and a blow pipe is sealed and inserted into the other end of the electromagnetic pulse valve. Multiple nozzles are sealed and inserted into the bottom of the blow pipe.
[0009] Furthermore, a perforated plate is snapped between the inner circumferential walls of the outer shell, and the nozzle is located above the perforated plate.
[0010] Furthermore, multiple Venturi tubes are snapped onto the porous plate, the nozzles are aligned with the Venturi tubes, and filter bags are fitted onto the cages at the bottom of the Venturi tubes.
[0011] Furthermore, an air intake pipe is fixedly connected to one side of the outer casing, and the air intake pipe is located below the perforated plate.
[0012] Furthermore, an air outlet pipe is fixedly connected to one side of the top cover, and the air outlet pipe is located above the perforated plate.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. The dust on the base plate is monitored by a pressure sensor. When the set value is reached, the information is transmitted to the processor for processing.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figures 1-4 A cylindrical pulse dust collector includes a shell 1, a transport trolley 14 and a processor. The processor is model ARM9TDMI. The top of the shell 1 is connected to a top cover 2 via a flange, and the bottom of the shell 1 is connected to a collection hopper 3 via a flange. A support 6 is welded to the outer circumference of the collection hopper 3. Two grooves 13 are provided on the inner bottom wall of the support 6. The rollers of the transport trolley 14 roll in the grooves 13.
[0023] The bottom of the collecting hopper 3 is integrally formed with a first retaining plate 4. The bottom of the collecting hopper 3 is equipped with a solenoid valve 5. The bottom of the first retaining plate 4 is equipped with a second retaining plate 7. A clamp 12 is sleeved on the outer circumference between the second retaining plate 7 and the first retaining plate 4. By removing the clamp 12, the second retaining plate 7 can be removed from the first retaining plate 4, which facilitates the cleaning of dust.
[0024] The bottom of the second card tray 7 is welded with a top plate 8, the bottom of the top plate 8 is fixed with a corrugated pipe 9, and the bottom of the corrugated pipe 9 is fixed with a base plate 10. The top of the transport trolley 14 is fixed with multiple pressure sensors 15 by bolts, and the top of the transport trolley 14 is fixed with two warning lights 16 by bolts. The base plate 10 is placed on top of the multiple pressure sensors 15. The pressure sensors 15 monitor the dust on the base plate 10. When the set value is reached, the information is transmitted to the processor for processing. Then, the processor controls the solenoid valve 5 to close, and at the same time, the warning lights 16 start to flash to remind the staff to clean.
[0025] An air inlet pipe 24 is welded to one side of the outer casing 1, through which flue gas enters the outer casing 1. An air outlet pipe 25 is welded to one side of the top cover 2, through which gas is discharged.
[0026] A perforated plate 21 is snapped between the inner circumference of the outer casing 1, the air inlet pipe 24 is located below the perforated plate 21, and the air outlet pipe 25 is located above the perforated plate 21.
[0027] Multiple Venturi tubes 22 are snapped onto the perforated plate 21. Filter bags 23 are fitted onto the cages at the bottom of the Venturi tubes 22. When flue gas flows through the filter bags 23, dust is blocked and adsorbed on the surface of the filter bags 23. Then, the gas enters the filter bags 23 through the pores and is discharged from the Venturi tubes 22, thus achieving pulse dust removal.
[0028] An air supply bag 17 is provided on one side of the outer casing 1. Multiple electromagnetic pulse valves 18 are sealed and inserted into the top of the air supply bag 17. A blow pipe 19 is sealed and inserted into the other end of the electromagnetic pulse valve 18. Multiple nozzles 20 are sealed and inserted into the bottom of the blow pipe 19. The nozzles 20 spray air in one direction. The nozzles 20 are located above the perforated plate 21 and are aligned with the Venturi tube 22. The nozzles 20 are cleaned regularly.
[0029] Under the action of an external air compressor, gas is input from the air supply pipe into the air supply manifold 17, and then input into the blow pipe 19 through the electromagnetic pulse valve 18. Then, the gas is sprayed from the nozzle 20 onto the filter bag 23, thereby blowing away the dust on the surface of the filter bag 23 by reverse air blowing.
[0030] The processor is connected to the solenoid valve 5, pressure sensor 15 and warning light 16 via wires. The pressure sensor 15 is model JYB-KB-CW-2000.
[0031] Multiple guide shafts 11 are welded to the top of the base plate 10, and the top ends of the guide shafts 11 pass through the top plate 8.
[0032] The working principle of this embodiment is as follows: When in use, an air supply pipe is installed at the bottom of the air supply manifold 17, and the other end of the air supply pipe is connected to the air outlet of the air compressor. The solenoid valve 5 is in the open state.
[0033] First, the flue gas enters the housing 1 through the inlet pipe 24. Then, when the flue gas flows through the filter bag 23, the dust is blocked and adsorbed on the surface of the filter bag 23. Then, the gas enters the filter bag 23 through the air holes. Next, the gas is discharged from the Venturi tube 22 and then from the outlet pipe 25.
[0034] Then, the dust falls into the collection hopper 3, and then falls onto the base plate 10 through the solenoid valve 5 and the bellows 9. At the same time, the dust on the base plate 10 is monitored by the pressure sensor 15. When the set value is reached, the information is transmitted to the processor for processing. Then, the processor controls the solenoid valve 5 to close, and the warning light 16 starts to flash to remind the staff to clean it. Then, the clamp 12 is removed to remove the second clamp plate 7 from the first clamp plate 4, which facilitates the disassembly of the bellows 9 and the base plate 10, and makes it easier to clean the dust on the base plate 10. After cleaning, the second clamp plate 7 is fixedly installed on the first clamp plate 4 by the clamp 12, and the top plate 8 passes through the top of the guide shaft 11 to facilitate the support of the bellows 9. Then, the solenoid valve 5 is controlled to open to continue the dust removal process.
[0035] When the filter bag 23 needs to be cleaned, the pulse dust collector stops working, the electromagnetic pulse valve 18 opens, and the air compressor is started. Under the action of the air compressor, the gas is input from the air supply pipe into the air supply manifold 17, and then input into the blow pipe 19 through the electromagnetic pulse valve 18. Then, the gas is sprayed from the nozzle 20 onto the filter bag 23, thereby blowing the dust off the surface of the filter bag 23 by reverse blowing. Then, the dust falls onto the base plate 10.
[0036] When the nozzle 20 needs to be cleaned, open the top cover 2, remove it, and manually clean the nozzle 20.
[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
