Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment, specifically a bag electrostatic precipitator. Background Technology

[0002] The baghouse electrostatic precipitator combines the characteristics of electrostatic precipitators and baghouse filters. It is a highly efficient dust collector that utilizes pre-collection and charging in the front-stage electric field and filtration in the rear-stage filter bag area. It fully leverages the individual dust removal advantages of electrostatic precipitators and baghouse filters, as well as the new performance advantages resulting from their combination, thus overcoming the shortcomings of both individual dust collectors. This composite dust collector boasts advantages such as high efficiency, stability, and low filter bag resistance. However, there are still some areas for improvement in the use of baghouse electrostatic precipitators: in existing models, the filter bags, anode plates, and cathode plates are relatively fixed, making disassembly and maintenance often cumbersome. Utility Model Content

[0003] The purpose of this utility model is to provide a bag electrostatic precipitator to solve the problem mentioned in the background art that the filter bags, anode plates and cathode plates in existing bag electrostatic precipitators are relatively fixed, which is often troublesome when maintenance and disassembly are required.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a bag electrostatic precipitator, comprising: a smoke inlet box, a pushing component, and a fixing component;

[0005] Among them: two electrode plates, one negative and one positive, are symmetrically arranged on both sides of the inner wall of the smoke inlet box, and a filter box is installed on one side of the smoke inlet box;

[0006] The pushing component includes guide rails installed on both sides of the smoke inlet box. A support frame is slidably installed on the surface of the guide rails. Two wheels are rotatably installed at the bottom ends of the support frame. The wheels are rolled on the surface of the guide rails. A rotating motor is installed on one side of the top of the support frame. The output end of the rotating motor is connected to one of the wheels.

[0007] The fixing assembly includes a mounting frame installed on one side of the top of the support frame. A bidirectional lead screw is rotatably mounted inside the mounting frame. Both ends of the bidirectional lead screw are threaded with fixing clips. Two limiting grooves are formed on the surface of the mounting frame. The fixing clips are inserted into the limiting grooves, and the electrode plate is fixed inside the fixing clips.

[0008] As a preferred embodiment of this utility model: the output end of the rotating motor is fixedly equipped with a driving pulley, and a driven pulley is installed on one side of one of the walking wheels. The driving pulley and the driven pulley are connected by a transmission belt.

[0009] As a preferred embodiment of this utility model: a stepper motor is installed on the back of the mounting frame, a worm gear is installed at the output end of the stepper motor, and a worm is fixedly installed in the middle of the bidirectional lead screw, with the worm meshing with the worm gear.

[0010] As a preferred embodiment of this utility model: a dust collection hopper is installed at the bottom of the filter box, a discharge pipe is installed at the bottom of the dust collection hopper, a spiral auger is rotatably installed inside the discharge pipe, a drive motor is installed at one end of the discharge pipe, and the output end of the drive motor is fixedly connected to one end of the spiral auger.

[0014] (1) An installation frame is installed on one side of the top of the support frame. A bidirectional screw is rotatably installed inside the installation frame. When the stepper motor rotates, it drives the worm gear to rotate. The worm gear drives the worm to rotate, which causes the bidirectional screw to rotate inside the installation frame. The rotation of the bidirectional screw causes the fixed clamps connected by threads at both ends to slide along the bidirectional screw under the limit of the limit groove. The two fixed clamps slide close to fix and clamp the electrode plate, which is convenient for the installation of the electrode plate. When disassembling, the two fixed clamps on the surface of the bidirectional screw are controlled to slide away from each other, so that the electrode plate can be removed for maintenance, making the electrode plate easy to disassemble and install.

[0015] (2) With the provided push component, after the electrode plate maintenance is completed, the control rotation motor drives the output end of the active pulley to rotate. The rotation of the active pulley drives the driven pulley to rotate through the transmission belt. The rotation of the driven pulley drives the walking wheel at one end of the support frame to move on the guide rail surface, which facilitates pushing the electrode plate installed on the surface of the mounting frame to the inner wall of the smoke inlet box.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please see Figures 1-4 A bag electrostatic precipitator includes: a smoke inlet box 1, a pushing component 4 and a fixing component 5; two electrode plates 2, a cathode and a cathode, are symmetrically arranged on both sides of the inner wall of the smoke inlet box 1, and a filter box 3 is installed on one side of the smoke inlet box 1.

[0023] Please see Figure 1 , Figure 2 The pushing component 4 includes guide rails 41 corresponding to both sides of the smoke inlet box 1. A support frame 42 is slidably mounted on the surface of the guide rails 41. Two walking wheels 43 are rotatably mounted on the bottom ends of the support frame 42. The walking wheels 43 are rolled on the surface of the guide rails 41. A rotating motor 44 is mounted on one side of the top of the support frame 42. The output end of the rotating motor 44 is connected to one of the walking wheels 43. A drive pulley 45 is fixedly mounted on the output end of the rotating motor 44. A driven pulley 46 is mounted on one side of one of the walking wheels 43. The drive pulley 45 and the driven pulley 46 are connected by a transmission belt 47.

[0024] In practical use: After the maintenance of the electrode plate 2 is completed, the control motor 44 drives the output end of the active pulley 45 to rotate. The rotation of the active pulley 45 drives the driven pulley 46 to rotate through the transmission belt 47. The rotation of the driven pulley 46 drives the walking wheel 43 at one end of the support frame 42 to move on the surface of the guide rail 41, so as to push the electrode plate 2 installed on the surface of the mounting frame 51 to the inner wall of the smoke inlet box 1.

[0025] Please see Figure 1 , Figure 3 The fixing component 5 includes a mounting frame 51 installed on one side of the top of the support frame 42. A bidirectional lead screw 52 is rotatably mounted inside the mounting frame 51. Both ends of the bidirectional lead screw 52 are threadedly connected to fixing clips 53. Two limiting grooves 54 are opened on the surface of the mounting frame 51. The fixing clips 53 are inserted into the limiting grooves 54. The electrode plate 2 is fixed inside the fixing clips 53. A stepper motor 55 is mounted on the back of the mounting frame 51. A worm gear 56 is mounted on the output end of the stepper motor 55. A worm 57 is fixedly mounted in the middle of the bidirectional lead screw 52. The worm 57 is meshed with the worm gear 56.

[0026] In practical use: An installation frame 51 is installed on one side of the top of the support frame 42. A bidirectional lead screw 52 is rotatably installed inside the installation frame 51. When the stepper motor 55 rotates, it drives the worm gear 56 to rotate. The worm gear 56 drives the worm 57 to rotate, so that the bidirectional lead screw 52 rotates inside the installation frame 51. The rotation of the bidirectional lead screw 52 causes the fixing clips 53 with threads at both ends to slide along the bidirectional lead screw 52 under the limit of the limiting groove 54. The two fixing clips 53 slide close to fix the electrode plate 2, which is convenient for the installation of the electrode plate 2. When disassembling, the two fixing clips 53 on the surface of the bidirectional lead screw 52 are controlled to slide away from each other, so that the electrode plate 2 can be removed for maintenance.

[0027] Please see Figure 1 , Figure 4 The bottom of the filter box 3 is equipped with a dust collection hopper 6, the bottom of the dust collection hopper 6 is equipped with a discharge pipe 7, a spiral auger 8 is rotatably installed inside the discharge pipe 7, a drive motor 9 is installed at one end of the discharge pipe 7, and the output end of the drive motor 9 is fixedly connected to one end of the spiral auger 8.

[0028] In practical use: The bottom of the filter box 3 is equipped with a dust collection hopper 6. The filtered dust falls into the discharge pipe 7 through the dust collection hopper 6. After the drive motor 9 at one end of the discharge pipe 7 rotates, it drives the spiral auger 8 to rotate in the discharge pipe 7, which facilitates the transportation of dust.

[0029] Please see Figure 1 The filter box 3 is equipped with a dust collector bag 10 inside and an air manifold 11 outside. A pulse valve 12 is installed on the surface of the air manifold 11, and an air blow pipe 13 is installed on the surface of the pulse valve 12. The air blow pipe 13 is correspondingly set on the top of the dust collector bag 10.

[0030] In practical use: The dust collector bag 10 inside the filter box 3 is used to filter dust in the flue gas. When the pulse valve 12 is opened, the high-pressure gas inside the air tank 11 is blown to the dust collector bag 10 through the air blow pipe 13, which makes it easier to blow off the dust on the surface of the dust collector bag 10.

[0031] Please see Figure 1A negative pressure exhaust fan 14 is installed on the top of the filter box 3.

[0032] In practical use: The negative pressure exhaust fan 14 installed on the top of the filter box 3 facilitates the discharge of the filtered gas.

[0033] A mounting frame 51 is installed on one side of the top of the support frame 42. A bidirectional lead screw 52 is rotatably mounted inside the mounting frame 51. When the stepper motor 55 rotates, it drives the worm gear 56 to rotate. The worm gear 56 drives the worm 57 to rotate, thereby causing the bidirectional lead screw 52 to rotate inside the mounting frame 51. The rotation of the bidirectional lead screw 52 causes the fixing clips 53 with threads at both ends to slide along the bidirectional lead screw 52 under the limit of the limiting groove 54. The two fixing clips 53 slide close to fix the electrode plate 2, which is convenient for the installation of the electrode plate 2. When disassembling, the two fixing clips 53 on the surface of the bidirectional lead screw 52 are controlled to slide away from each other, so that the electrode plate 2 can be removed for maintenance.
