In view of the problem that dust collecting plates in the prior art are prone to accumulating dust, leading to abnormal corona discharge, the following scheme is proposed, which comprises a main frame, a gas outlet pipe and a gas inlet pipe are arranged on the main frame, and a plurality of inclined and mutually parallel dust removing units are arranged between the pipe bodies of the gas outlet pipe and the gas inlet pipe.

In the application, when gas is removed, the inner wall of the rotating anode dust collecting plate and the spiral cleaning plate form relative operation, thereby timely scraping off the dust adsorbed on the inner wall of the anode dust collecting plate, so as to ensure uniform electric field distribution, ensure stable high-voltage power supply load, and avoid power consumption increase caused by dust accumulation.

Description

Technical Field

[0001] This invention relates to the field of electrostatic dust removal technology, and in particular to a self-cleaning rotary electrostatic dust collector. Background Technology

[0002] With the continuous acceleration of industrialization, the situation of air pollution control and treatment is becoming increasingly severe. Solid waste pollution and air pollution problems are becoming increasingly prominent, which not only seriously threaten ecological protection and human health, but also restrict sustainable development. Therefore, strengthening environmental protection, promoting air purification, and implementing air pollution control and treatment measures have become a global consensus. As a highly efficient air purification device, electrostatic dust collection devices are widely used in various scenarios such as industrial flue gas treatment and indoor air purification due to their significant advantages of low energy consumption and high dust collection efficiency. They have become an important piece of equipment for air pollution control and treatment and for protecting the ecological environment.

[0003] However, during long-term operation, traditional electrostatic precipitators easily accumulate large amounts of dust on their collecting plates. If not cleaned in time, this can lead to abnormal corona discharge, a significant decrease in air purification efficiency, and a shortened lifespan of the equipment. Existing dust removal methods mostly rely on manual disassembly, which is not only time-consuming and labor-intensive with high maintenance costs, but may also cause secondary dust re-entrainment, violating the core principles of environmental protection and failing to meet the practical needs of normalized and efficient air control and pollution treatment.

[0004] Based on this, in order to effectively solve the above problems, meet the core needs of ecological protection and air purification, and adapt to the development trend of the atmospheric control and pollution control industry, our company has developed a self-cleaning rotary electrostatic dust collection device. Summary of the Invention

[0005] To overcome the aforementioned shortcomings of the prior art, the present invention aims to provide a self-cleaning electrostatic dust collection device by providing a dust scraping mechanism that can move relative to and closely adhere to the dust accumulation surface. This invention provides a self-cleaning rotary electrostatic dust collector, comprising a main frame. The main frame is characterized by an outlet pipe and an inlet pipe, with multiple inclined and parallel dust collection units positioned between the pipe bodies. Each dust collection unit includes a fixed tube (first and second) fixed to the outer walls of the outlet and inlet pipes, respectively. Each fixed tube has a pre-drilled flared end with a collinear axis at one opposite end. A rotating drum is rotatably connected between the two flared tubes. An anode dust collection plate is detachably fixed to the inner circumference of the rotating drum. The anode dust collection plate is wound into a cylindrical shape and tightly adhered to the inner circumference of the rotating drum. A discharge electrode extending into the middle of the anode dust collection plate is positioned near the top of the inner wall of the fixed tube, with its main body coinciding with the axis of the rotating drum. A spiral cleaning plate is positioned on the inner circumference of the anode dust collection plate, forming a sliding contact with the inner circumference of the anode dust collection plate.

[0006] The preferred embodiment is that the main frame includes two U-shaped side panels, the openings of which face upward and include a high-end hole and a low-end hole. An exhaust pipe is inserted and fixed between the two high-end holes, and an intake pipe is inserted between the two low-end holes. The sides of the exhaust and intake pipes that are close to each other are respectively provided with a corresponding number of mating holes. The same set of mating holes constitutes the same dust removal unit. The bottom end of the spiral cleaning plate is fixed to the inner wall of the fixed tube, and the top end of the spiral cleaning plate is slidably fixed. The inner circumference of the fixed tube is one; all the lower surfaces of the fixed tubes are provided with material-gathering funnels between the air inlet pipe and the rotating drum; the bottom of all the material-gathering funnels is provided with the same spiral discharge mechanism, and the spiral discharge mechanism includes a discharge pipe horizontally arranged between the bottom ends of two U-shaped side plate frames, and a spiral rod is rotatably connected inside the discharge pipe, with a drive motor provided at one end of the spiral rod; the bottom end of all the material-gathering funnels is connected to the body of the discharge pipe; the scraped dust can be transported out in time to keep the inside of the dust removal unit clean.

[0007] The preferred aspect is that the outer circumference of the spiral rod is provided with equally spaced grooves, and a compression spring is fixed to the inner wall of one end of each groove. One end of the compression spring is raised outward, and a hammer is provided at the raised end of each compression spring. When the compression spring with the hammer rotates to the bottom opening of the material collection funnel, the hammer, which is restricted by the inner wall of the discharge pipe, quickly bounces up due to the sudden increase in space. This causes the hammer to strike the bottom opening of the material collection funnel, creating a vibration impact. This shakes the dust accumulated at the opening of the material collection funnel into the spiral discharge mechanism, so as to smoothly transport the accumulated solid waste out.

[0008] The preferred embodiment is that an L-shaped fixing plate is fixed to the top of the spiral cleaning plate, and an arc-shaped sliding cover plate is fixed to the L-shaped fixing plate, which is tightly attached to the inner wall of the fixed tube. The tube wall of the fixed tube has a strip-shaped sliding hole (II) adapted to the L-shaped fixing plate near the top of the spiral cleaning plate. One end of each L-shaped fixing plate passes through the corresponding strip-shaped sliding hole (II) and is fixed with the same horizontal tie rod. The spiral cleaning plate is made of spring steel and has a certain elastic recovery capability. The two U-shaped side plate frames each have a strip-shaped sliding hole (I) adapted to the sliding trajectory of the tie rod (II) near their tops. The length direction of the strip-shaped sliding hole (I) is parallel to the axis of the tube. When the L-shaped fixing plate is pulled, the arc-shaped sliding cover plate always covers the strip-shaped sliding hole (II) to prevent air leakage. A downwardly extending fixing bracket is fixed to the outer wall of the air outlet near the middle, and the fixing bracket includes... A fixed pulley is installed diagonally above the middle of the device near the tie rod plate. The bottom end of the fixed hanger is fitted with a vertical grooved slide rail with its opening facing the rear of the device. A convex slider is slidably connected in the grooved slide rail. An impact column is fixed to the side of the convex slider away from the bottom of the groove. A connecting line is fixed to the top of the convex slider. The connecting line goes upward around the fixed pulley and is fixed to the tie rod plate. A pull rope is fixed to the bottom of the convex slider. Triangular fixing plates are fixed to the rear outer wall of all the fixed tubes near the top. The same impact rod is fixed to the end of all the triangular fixing plates away from the fixed tubes. The impact rod is located directly above the impact column. The pull rope can be pulled down first and then quickly released to produce a manual impact dust removal effect on all dust removal units. The impact sensitivity can also detect the internal blockage and determine whether a systematic dust cleaning is needed.

[0009] The preferred feature is that multiple staggered turbulence insulating plates are fixed on the rod of the discharge electrode, and the outer circumferential wall of all the turbulence insulating plates does not contact the spiral cleaning plate. All the turbulence insulating plates force the gas to be purified to form an S-shaped flow channel. The turbulence insulating plates are made of corrosion-resistant material.

[0010] The preferred feature is that the wall of the fixed tube is provided with an insulating sleeve and a sealing device near the top of the discharge electrode, which, together with the setting of the turbulence insulating plate, improves the insulation effect of the discharge electrode.

[0011] The preferred aspect is that the spacing between two adjacent turbulence insulating plates is the same, and the angle between the surface of the turbulence insulating plate and the horizontal plane is between 80° and 90°, which facilitates airflow and reduces the swaying effect of wind resistance on the discharge electrode.

[0012] The preferred embodiment is that the rotating drum includes two mutually symmetrical upper and lower rotating tubes with coincident axes. Sealed bearings are provided on the outer circumference of the opposite ends of the upper and lower rotating tubes. The outer rings of the two sealed bearings are fixed to the inner walls of the flared ends of the corresponding fixed tubes (first and second). Connecting rods are fixed between the opposite outer circumferences of the upper and lower rotating tubes. The number of connecting rods on the outer walls of the upper and lower rotating tubes is the same, and their opposite ends are detachably fixed together. The main body of the connecting rod is parallel to the surface of the first fixed tube. The tube has two oblique insertion notches with opposite openings on a straight line. The anode dust collection plate is inserted into the two oblique insertion notches and rolled into a cylindrical shape. All connecting rods on the outer wall of the lower rotating tube are fixed with the same C-shaped gear ring, and the notch of the C-shaped gear ring is aligned with the oblique insertion notch, ensuring that the anode dust collection plate can be pulled out and inserted normally. This design not only facilitates the installation of the anode dust collection plate and makes it easier to disassemble and clean the anode dust collection plate during systematic cleaning, but also exposes most of the internal space after the anode dust collection plate is pulled out, making it easy to clean.

[0013] The preferred embodiment is that two U-shaped side plate frames are respectively fixed with connecting rod beams near the middle, and the upper surfaces of the two connecting rod beams are respectively fixed with coaxial and horizontal bearing seats. Anti-torsion bearings are embedded in both bearing seats, and the same rack and pinion is slidably connected between the two anti-torsion bearings. The rack and pinion simultaneously meshes with all C-shaped gear rings. A bearing bracket is fixed to the outer wall of the air intake pipe between the two sets of dust removal units near the middle, and a central shaft is fixed to the top of the bearing bracket. A swing lever is rotatably connected to the top of the central shaft, and the two sides of the swing lever... Each end has a slotted hole in the middle; a protruding rod is fixed to the outer wall of the rack push rod near the end of the swing lever, extending into the slotted hole; the bottom of the main frame is fixed with a bottom beam for connecting two U-shaped side plate frames, a motor bracket is fixed to the middle of the upper surface of the bottom beam, a geared motor is fixed to the top of the motor bracket, and a wheel is fixed to the top of the output shaft of the geared motor. A protruding rod is provided on the upper surface of the wheel, which is inserted into another slotted hole of the swing lever. Thus, the rack push rod can be moved back and forth by controlling the rotation of the wheel, thereby driving all the drums to rotate periodically.

[0014] A preferred feature is that a putty auxiliary plug is fixed at one end of the upper and lower rotating tubes near the oblique insertion notch, and a sealing putty is provided at the putty auxiliary plug to fill the gap.

[0015] The beneficial effects of this invention are as follows: 1. By setting an anode dust collection plate that can rotate with the rotating drum, and a spiral cleaning plate that is in close contact with its inner wall, the inner wall of the rotating anode dust collection plate and the spiral cleaning plate can be made to run relative to each other during gas dust removal. This allows the dust adsorbed on the inner wall of the anode dust collection plate to be scraped off in time, ensuring uniform electric field distribution, stable high-voltage power supply load, and avoiding increased power consumption due to dust accumulation.

[0016] 2. Through the striking mechanism set on the screw rod, when the compressed spring with the striking hammer rotates to the bottom opening of the material collection funnel, the space suddenly expands, and the striking hammer, which is restricted by the inner wall of the discharge pipe, quickly bounces up and strikes the bottom opening of the material collection funnel, forming a vibration strike. This shakes the dust accumulated at the opening of the material collection funnel into the screw discharge mechanism, so as to smoothly transport the accumulated solid waste out.

[0017] 3. With the pull rope and impact rod, the pull rope can be pulled down and then quickly released to manually impact and remove dust from all dust collection units. The impact sensitivity can also be used to detect internal blockages and determine whether systemic cleaning is required.

[0018] 4. By setting up turbulence-insulating plates that are staggered on the outer wall of the discharge electrode, the residence time of air in the electrostatic field is extended, the air has more sufficient contact with the anode dust collection plate and a longer residence time, and charged dust has ample opportunity to be electrostatically adsorbed by the anode dust collection plate, thus greatly improving the air purification efficiency.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] In this embodiment, refer to Figures 1-10 A self-cleaning rotary electrostatic dust collector includes a main frame 1. The main frame 1 is characterized by having an air outlet pipe 2 and an air inlet pipe 7 that are at different heights and parallel to each other. Multiple inclined and parallel dust removal units are arranged between the air outlet pipe 2 and the air inlet pipe 7. The dust removal unit includes a fixed tube 1 20 and a fixed tube 22 fixed to the outer walls of the air outlet pipe 2 and the air inlet pipe 7, respectively. The fixed tube 1 20 and the fixed tube 2 22 have flared tubes with collinear axes at their opposite ends. The two flared tubes are rotatably connected to the same rotating drum 3. An anode dust collection plate 24 is detachably fixed to the inner circumference of the rotating drum 3. The anode dust collection plate 24 is wound into a cylindrical shape and tightly attached to the inner circumference of the rotating drum 3. A discharge electrode 25 extending into the middle of the anode dust collection plate 24 is provided near the top of the inner wall of the fixed tube 20. The main body of the discharge electrode 25 coincides with the axis of the rotating drum 3. A spiral cleaning plate 26 is provided on the inner circumference of the anode dust collection plate 24. The spiral cleaning plate 26 forms a sliding contact with the inner circumference of the anode dust collection plate 24. By setting the anode dust collection plate 24, which can rotate with the rotating drum 3, and the spiral cleaning plate 26, which is in close contact with its inner wall, the inner wall of the rotating anode dust collection plate 24 and the spiral cleaning plate 26 can be made to run relative to each other during gas dust removal. This allows the dust adsorbed on the inner wall of the anode dust collection plate 24 to be scraped off in time, so as to ensure uniform electric field distribution, ensure stable high-voltage power supply load, and avoid increased power consumption due to dust accumulation.

[0023] The main frame 1 includes two U-shaped side panels. The openings of the U-shaped side panels face upward and include a high-end hole 1 and a low-end hole 2. The exhaust pipe 2 is inserted and fixed between the two high-end holes 1, and the intake pipe 7 is inserted between the two low-end holes 2. The sides of the exhaust pipe 2 and the intake pipe 7 that are close to each other are respectively provided with a corresponding number of docking holes 1 and 2 701. The same set of docking holes 1 and 2 701 constitutes the same dust removal unit. The bottom end of the spiral cleaning plate 26 is fixed to the inner wall of the fixed tube 22, and the top end of the spiral cleaning plate 26 is slidably fixed to the circumference of the fixed tube 20. The lower surface of all fixed tubes 22, between the air inlet pipe 7 and the rotating drum 3, is provided with a material gathering funnel 23; the bottom end of all material gathering funnels 23 is provided with the same spiral discharge mechanism 15, and the spiral discharge mechanism 15 includes a discharge pipe horizontally arranged between the bottom ends of two U-shaped side plate frames, and a spiral rod is rotatably connected inside the discharge pipe, with a drive motor 10 provided at one end of the spiral rod; the bottom end of all material gathering funnels 23 is connected to the body of the discharge pipe; through the spiral discharge mechanism 15, the scraped dust can be transported out in time, keeping the inside of the dust removal unit clean.

[0024] Reference Figures 3-4 The outer circumference of the screw rod is provided with equally spaced grooves, and a compression spring is fixed to the inner wall of one end of each groove. One end of the compression spring is raised outward, and a hammer is provided at the raised end of each compression spring. When the compression spring with the hammer rotates to the bottom opening of the material collection funnel 23, the space suddenly increases, and the hammer, which is restricted by the inner wall of the discharge pipe, quickly bounces up and hits the bottom opening of the material collection funnel 23, forming a vibration and knocking. This knocks the dust accumulated at the opening of the material collection funnel 23 into the screw discharge mechanism 15, so that the accumulated solid waste can be smoothly transported out.

[0025] Reference Figure 2 , Figure 3 , Figure 5 and Figure 8 The top of the spiral cleaning plate 26 is fixed with an L-shaped fixing plate, and an arc-shaped sliding cover plate 2601 that is tightly attached to the inner wall of the fixed tube 20 is also fixed on the L-shaped fixing plate. The tube wall of the fixed tube 20 has a strip-shaped sliding hole 2001 that matches the top of the spiral cleaning plate 26. One end of each L-shaped fixing plate passes through the corresponding strip-shaped sliding hole 2001 and is fixed with the same horizontal tie rod strip 19. The spiral cleaning plate 26 is made of spring steel and has… With a certain degree of elastic recovery, the two U-shaped side plate frames are respectively provided with strip-shaped sliding holes 101 near the top, which are adapted to the sliding trajectory of the tie rod strip 19. The length direction of the strip-shaped sliding holes 101 is parallel to the axis of the tube 3. When the L-shaped fixed plate is pulled, the arc-shaped sliding cover plate 2601 always covers the strip-shaped sliding holes 2001 to avoid air leakage. The outer wall of the air outlet pipe 2 is fixed with a downwardly extending fixed hanger 17 near the middle, and the fixed hanger 17 includes the middle part near the middle. A fixed pulley is installed diagonally above the pull rod strip 19. The bottom end of the fixed hanger 17 is located below the fixed pulley and is fitted with a vertical grooved slide rail 1701 with its opening facing the rear of the device. A convex slider is slidably connected in the grooved slide rail 1701. An impact column 18 is fixed on the side of the convex slider away from the bottom of the groove. A connecting line is fixed to the top of the convex slider. The connecting line goes upward around the fixed pulley and is fixed to the pull rod strip 19. A pull rope 11 is fixed to the bottom of the convex slider. Triangular fixing plates 2002 are fixed to the rear outer wall of all fixed tubes 20 near the top. The same impact rod 16 is fixed to the end of all triangular fixing plates 2002 away from the fixed tubes 20. The impact rod 16 is located directly above the impact column 18. With this arrangement, the pull rope 11 can be pulled down first and then quickly released, thereby producing a manual impact dust removal effect on all dust removal units. The impact sensitivity can also be used to detect the internal blockage and determine whether a systematic dust cleaning is needed.

[0026] Reference Figure 4 Multiple staggered turbulence insulating plates 2501 are fixed on the rod of the discharge electrode 25, and the outer circumference of all the turbulence insulating plates 2501 does not contact the spiral cleaning plate 26. All the turbulence insulating plates 2501 force the gas to be purified to form an S-shaped flow channel. The turbulence insulating plates 2501 are made of corrosion-resistant material. By setting the turbulence insulating plates 2501 staggered on the outer wall of the discharge electrode 25, the residence time of air in the electrostatic field is extended. The air has more sufficient contact with the anode dust collection plate 24 and a longer residence time. The charged dust has a sufficient opportunity to be electrostatically adsorbed by the anode dust collection plate 24, and the air purification efficiency is greatly improved.

[0027] In this invention, an insulating sleeve and sealing device are provided on the tube wall of the fixed tube 20 near the top of the discharge electrode 25. Together with the setting of the turbulence insulating plate 2501, the insulation effect of the discharge electrode 25 is improved.

[0028] Reference Figure 4 The spacing between two adjacent turbulence insulating plates 2501 is the same, and the angle between the surface of the turbulence insulating plate 2501 and the horizontal plane is between 80° and 90°, which facilitates airflow and reduces the swaying effect of wind resistance on the discharge electrode 25.

[0029] Reference Figures 7-10 The rotating drum includes two symmetrical upper rotating tubes 301 and lower rotating tubes 303 with their centerlines overlapping. Sealed bearings 27 are provided on the outer circumference of the opposite ends of both upper and lower rotating tubes 301 and 303. The outer rings of the two sealed bearings 27 are fixed to the inner walls of the flared ends of the corresponding fixed tubes 20 and 22. Connecting rods 302 are fixed between the opposite ends of the outer circumference of the upper and lower rotating tubes 301 and 303, respectively. The number of connecting rods 302 on the outer walls of the upper and lower rotating tubes 301 and 303 is the same, and their opposite ends are detachably fixed together. The main body of the connecting rod 302 is parallel to the surface of the fixed tube 20. The lower rotating tube 303 has two oblique insertion notches 305 with opposite openings on a straight line at opposite ends. The anode dust collection plate 24 is inserted into the two oblique insertion notches 305 and rolled into a cylindrical shape. All connecting rods 302 on the outer wall of the lower rotating tube 303 are fixed with the same C-shaped gear ring 21, and the notch of the C-shaped gear ring 21 is aligned with the oblique insertion notch 305 to ensure that the anode dust collection plate 24 can be pulled out and inserted normally. With this design, it is not only convenient to install the anode dust collection plate 24 and easy to disassemble and clean the anode dust collection plate 24 during systematic cleaning, but also after the anode dust collection plate 24 is pulled out, most of the internal space will be exposed, which is convenient for cleaning.

[0030] Reference Figure 2 , Figure 3 and Figure 5Two U-shaped side plate frames are fixed with connecting rod beams 6 near the middle, and coaxial and horizontal bearing seats 5 are fixed on the upper surfaces of the two connecting rod beams 6 respectively. Anti-torsion bearings are embedded in the two bearing seats 5, and the same rack push rod 4 is slidably connected between the two anti-torsion bearings. The rack push rod 4 meshes with all the C-shaped gear rings 21. A bearing bracket 9 is fixed on the outer wall of the air intake pipe 7 between the two sets of dust removal units near the middle, and a central shaft is fixed at the top of the bearing bracket 9. A swing lever 8 is rotatably connected to the top of the central shaft, and a strip hole is opened in the middle of both ends of the swing lever 8. A protruding rod 1 that extends into a slotted hole is fixed to the end of the outer wall of the push rod 4 near the end of the swing lever 8; a bottom beam 14 for connecting two U-shaped side plate frames is fixed to the bottom of the main frame 1, a motor bracket 1401 is fixed to the middle of the upper surface of the bottom beam 14, a geared motor 13 is fixed to the top of the motor bracket 1401, and a rotating wheel 12 is fixed to the top of the output shaft of the geared motor 13. A protruding rod 2 that inserts into another slotted hole of the swing lever 8 is provided on the upper surface of the rotating wheel 12, so that the rack push rod 4 can be moved back and forth by controlling the rotation of the rotating wheel 12, thereby driving all the rotating drums 3 to rotate periodically.

[0031] Reference Figure 7 At the opposite end of the upper rotating tube 301 and the lower rotating tube 303, near the oblique insertion notch 305, a putty auxiliary plug rod 304 is fixed, and a sealing putty for filling the gap is provided at the putty auxiliary plug rod 304.

[0032] Working principle: In actual operation, the dust-laden gas to be removed is continuously introduced into the inlet pipe 7, and at the same time, a high-voltage DC current with preset parameters is introduced into the discharge electrode 25 to ensure that the discharge electrode 25 can stably generate corona discharge, preparing for the dust to become charged; under the action of airflow pressure, the dust-laden gas smoothly enters each dust removal unit inside the device and flows precisely into the rotating drum 3 corresponding to each unit, realizing uniform gas distribution and ensuring that each dust removal unit can fully exert its purification function; As the gas flows through the rotating drum 3, with the proper placement of the turbulence-insulating plate 2501, the airflow is effectively guided, moving slowly upwards in a regular S-shape within the tubular cavity formed by the anode dust collection plate 24. During this process, the high-voltage electrostatic field generated by the discharge electrode 25 continuously acts on the airflow, fully ionizing and charging the dust particles in the gas. Simultaneously, the charged dust particles are firmly adsorbed by the grounded anode dust collection plate 24 under the influence of electrostatic attraction, achieving effective separation of dust and air. The clean air, after adsorption and purification, continues to flow upwards and finally enters the exhaust pipe 2, where it is discharged in an orderly manner, completing the core process of air purification. During the entire dust removal process, to prevent excessive dust accumulation on the inner wall of the anode dust collection plate 24 from affecting the purification efficiency, the rotating drum 3 continuously reciprocates under the drive of the rack and pinion 4. The reciprocating rotation of the rotating drum 3 drives the anode dust collection plate 24 to move synchronously, thereby making the inner wall of the anode dust collection plate 24 and the fixed spiral cleaning plate 26 form a stable relative operation. Through the relative friction and scraping between the two, the dust adsorbed on the inner wall of the anode dust collection plate 24 is scraped off in a timely and thorough manner, ensuring that the anode dust collection plate 24 is always kept clean. The scraped solid dust slides down under the action of gravity to the spiral discharge mechanism 15 at the bottom of the device for collecting dust. The spiral discharge mechanism 15 continuously and stably transports the dust to the designated collection position, realizing the centralized treatment of dust and avoiding secondary pollution.
