Description

Technical Field

[0001] The utility model relates to the technical field of purification equipment, in particular to a plate-type electrostatic purification device with a cleaning function. Background Art

[0002] Plate-type electrostatic purification devices utilize the principle of static electricity to attract and kill airborne particles and microorganisms. They primarily consist of an anode plate and a cathode plate. During operation, a high voltage is generated between the anode and cathode plates, creating a strong electric field. When airborne particles pass through this field, they become charged and then adhere to the anode plate. Simultaneously, the electric field inactivates some bacteria and viruses, effectively purifying the air.

[0003] Usually, dust and particles attached to the surface of the anode plate need to be cleaned. The traditional method is to remove the anode plate and then rinse it with cleaning fluid. This method is cumbersome and wastes a lot of labor costs.

[0004] To address the above problems, a plate-type electrostatic purification device that can achieve automatic cleaning has emerged, such as a new roller brush device for lead electrolysis residual anode plates disclosed in Chinese patent publication No. CN203281560U, which uses a roller brush combined with high-pressure water for flushing.

[0005] The plate-type electrostatic purification device in the existing technology uses a combination of a roller brush, a water inlet pipe, and a nozzle for cleaning. The structure is complex, and the roller brush is installed in the middle of the box. The motor for driving the roller brush is installed on the right side of the box, and the water inlet pipe is arranged on the front and rear sides of the box, which invisibly increases its overall structural size.

[0006] Therefore, the existing technology still needs to be improved and developed. Utility Model Content

[0009] Specifically, one end of the pipe is drivingly connected to the output shaft of the driving device, and the other end is connected to a joint that rotates with the end thereof, and the joint is connected to a water pipe.

[0010] Specifically, the driving device is fixed to the outside of the shell, the output shaft of the driving device extends into the inside of the shell, and a waterproof seal is provided at the junction of the output shaft of the driving device and the shell.

[0015] Specifically, a guide rail is provided in the shell, and a plurality of slots for limiting and fixing the anode plate are provided on the guide rail.

[0016] Beneficial effects of the utility model:

[0017] The plate-type electrostatic purification device of the present invention can be used to adsorb and kill particulate matter and microorganisms in gas. When the electrostatic field is turned on, a high-voltage electrostatic field is formed between the anode plate and the cathode plate. When gas passes between the anode plate and the cathode plate, particulate matter in the gas is charged and then adsorbed on the anode plate, achieving the effect of purifying the gas. After the plate-type electrostatic purification device has been running for a long time, a large amount of particulate matter may be adsorbed on the anode plate. The purification operation of the plate-type electrostatic purification device can be stopped, and water or cleaning liquid is introduced into the pipeline. The water or cleaning liquid is then sprayed through the nozzle to flush away the particulate matter attached to the surface of the anode plate. The rotary flushing device is arranged at the bottom position, which makes the entire device smaller in size and simpler in structure. Because the location at the lower end of the anode plate where more particulate matter accumulates is closer to the nozzle, the location at the lower end of the anode plate is flushed more cleanly under the action of the high-pressure water or high-pressure cleaning liquid sprayed from the nozzle. Since the location at the upper end of the anode plate where less particulate matter accumulates is less, the particulate matter at the upper end of the anode plate can be successfully flushed away even though the impact force of the high-pressure water or high-pressure cleaning liquid reaching this location is slightly weaker.

DETAILED DESCRIPTION

[0024] The present invention provides a plate-type electrostatic purification device with a cleaning function. To make the purpose, technical solution, and effects of the present invention more clear and explicit, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are only intended to explain the present invention and are not intended to limit the present invention.

[0025] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0026] like Figures 1 to 5, This embodiment discloses a plate-type electrostatic purification device with a cleaning function, including a shell 10, which is a box structure. The left and right ends of the shell 10 along the x-direction are respectively an air inlet 101 and an air outlet 102. In order to more intuitively see the internal structure of the shell 10, the top cover of the shell 10 is hidden in the figure. Two groups of electrostatic fields 20 are arranged side by side along the x-direction in the shell 10. The electrostatic field 20 includes a plurality of anode plates 21 and cathode plates (not shown) alternately arranged along the y-direction. A first interval 22 is provided between the two groups of electrostatic fields 20. A rotating flushing device 30 is provided at the bottom of the first interval 22. The rotating flushing device 30 includes a pipe 31 arranged along the y-direction, a plurality of nozzles 32 provided on the pipe 31, and a driving device 33 for driving the pipe 31 to rotate around the y-axis. A second interval 23 is provided between two adjacent anode plates 21, and one nozzle 32 is provided corresponding to one second interval 23.

[0027] The plate-type electrostatic purification device of this embodiment can be used to adsorb and kill particulate matter and microorganisms in the gas. Specifically, the gas can be introduced from the air inlet 101 of the outer shell 10. After the electrostatic field is turned on, a high-voltage electrostatic field is formed between the anode plate 21 and the cathode plate. When the gas passes between the anode plate 21 and the cathode plate, the particulate matter in the gas will be charged and then adsorbed on the anode plate 21. In addition, some bacteria and viruses will lose their activity due to the action of the electrostatic field, thereby achieving the effect of purifying the gas.

[0028] When the plate-type electrostatic purification device has been running for a long time, a large amount of particulate matter may be adsorbed on the anode plate 21. At this time, the purification work of the plate-type electrostatic purification device can be stopped, and water or cleaning liquid can be introduced into the pipe 31. The water or cleaning liquid is then sprayed out through the nozzle 32 to wash away the particulate matter attached to the surface of the anode plate 21.

[0029] In the prior art, some devices are designed with a spray head above the anode plate 21. In actual use, due to the limitations of the spray head's spray distance and range, the position of the anode plate 21 at the top close to the spray head will be cleaned more thoroughly, while the position at the bottom of the anode plate 21, far from the spray head, will accumulate more particles due to gravity. Since the distance above this position is far from the spray head, the particles at this position are not cleanly rinsed. Based on this, the present embodiment sets the rotary flushing device 30 at the bottom position. The size of the entire device is smaller and the structure is simpler. Since the position at the bottom of the anode plate 21 where more particles are accumulated is closer to the spray head 32, the position at the bottom of the anode plate 21 is cleaned more thoroughly under the action of the high-pressure water or high-pressure cleaning liquid sprayed by the spray head 32. Since the position at the top of the anode plate 21 where more particles are accumulated is less, although the impact force of the high-pressure water or high-pressure cleaning liquid reaching this position is slightly weaker, the particles at the top of the anode plate 21 can still be successfully rinsed away.

[0030] In addition, in this embodiment, a driving device 33 is provided. During the flushing process, the driving device 33 can drive the pipe 31 to rotate around the y-axis, so that the high-pressure water or high-pressure cleaning liquid ejected by the nozzle 32 can reach various positions on the surface of the anode plate 21, ensuring that the anode plate 21 is flushed clean.

[0031] For further information, please refer to Figure 3 and Figure 4 In this embodiment, one end of the pipe 31 is connected to the output shaft of the driving device 33, and the other end is connected to a joint 34 that rotates with its end. One end of the pipe 31 is designed to be rotatably matched with the joint 34. When the driving device 33 is started, it can smoothly drive the pipe 31 to rotate around the y-axis, thereby realizing the adjustment of the spray angle of the nozzle 32. The joint 34 is connected to a water pipe, and high-pressure water or high-pressure cleaning liquid is transported to the pipe 31 through the water pipe, and then sprayed out through the nozzle 32. The sprayed high-pressure water or high-pressure cleaning liquid is used to rinse various positions on the surface of the anode plate 21.

[0032] Please refer to Figures 1 to 4 In this embodiment, the driving device 33 is fixed to the outside of the shell 10 to prevent water from entering the driving device 33 and causing leakage. The output shaft of the driving device 33 extends into the inside of the shell 10. A waterproof seal 35 is provided at the junction of the output shaft of the driving device 33 and the shell 10. The waterproof seal 35 can be made of a rubber kit, a silicone kit or other components with good waterproof performance. By providing the waterproof seal 35, water in the shell 10 can be prevented from leaking from the junction of the output shaft of the driving device 33 and the shell 10, thereby improving the waterproof sealing performance of the shell 10.

[0033] Furthermore, the driving device 33 of this embodiment includes a reduction motor and a coupling. One end of the pipe 31 is blocked by a plug, and one end of the plug is connected to a rotating shaft. The rotating shaft serves as the output shaft of the driving device 33. A coupling is used to connect the rotating shaft and the driving shaft of the reduction motor. They rotate together during the process of transmitting motion and power, and do not disengage under normal circumstances. In addition, this embodiment adopts a reduction motor, and the reduction device of the reduction motor (such as a gear box or a transmission belt) reduces the output speed and increases the output torque to adapt to different rotary flushing requirements.

[0034] Furthermore, a first water trough 11 is provided at the bottom of the shell 10 of this embodiment, which is corresponding to the position of the electrostatic field 20, and a first drain outlet 12 is provided at either end of the first water trough 11 along the y direction. In the gas purification stage, the first water trough 11 serves as a temporary storage area for particulate matter and oily substances. Part of the purified particulate matter and oily substances accumulate in the first water trough 11 under the action of gravity. Moreover, the left and right sides of the bottom of the shell 10 of this embodiment have a first trapezoidal plate that is larger at the top and smaller at the bottom, so that the cross-section of the first water trough 11 is a trapezoidal structure that is larger at the top and smaller at the bottom. Particulate matter and oily substances can slide along the inclined inner wall of the first water trough 11 to the bottom of the first water trough 11 for collection. In the subsequent flushing stage, water and cleaning liquid will fall into the first water trough 11, thereby taking away the particulate matter and oily substances in the first water trough 11, and finally discharged through the first drain outlet 12.

[0035] In addition, please refer to Figure 5 In the gas purification stage, in order to prevent the gas from passing directly through the first water tank 11 without passing through the electrostatic field formed between the anode plate 21 and the cathode plate, resulting in incomplete gas purification, a windshield 13 extending along the y direction is further provided in the first water tank 11 of this embodiment. The windshield 13 has a blocking effect to prevent the gas from passing directly through the first water tank 11.

[0036] Furthermore, for the purification of some oil fume gas, the oil fume gas contains a large amount of oil substances. After being adsorbed on the anode plate 21, the oil fume gas will drip into the first water tank 11 along the anode plate 21, and the oil substances will agglomerate due to the influence of low temperature, resulting in a thicker layer of oil substances deposited inside the first water tank 11. In order to avoid the oil substances from agglomerating at the bottom inside the first water tank 11, the wind shield 13 of this embodiment is provided with insulation pipes 14 on both sides along the x direction. The insulation pipes 14 can pass high-temperature media, such as hot water, thermal oil, etc., to increase the temperature of the bottom inside the first water tank 11 through heat exchange, thereby avoiding the oil substances from agglomerating at the bottom inside the first water tank 11.

[0037] For further information, please refer to Figure 5 In this embodiment, a second water trough 15 is provided at the bottom of the shell 10 corresponding to the position of the first spacer 22, and a second trapezoidal plate with a larger upper portion and a smaller lower portion is provided in the middle position of the bottom of the shell 10. The second water trough 15 is formed at the upper end of the second trapezoidal plate. The cross-section of the first water trough 11 is a trapezoidal structure with a larger upper portion and a smaller lower portion. The pipe 31 and the nozzle 32 are located in the second water trough 15. A second drain port 16 is provided at either end of the second water trough 15 along the y direction. Part of the water or cleaning liquid after being sprayed will fall into the second water trough 15 and then be discharged through the second drain port 16.

[0038] Please refer to Figure 3In this embodiment, a guide rail 17 is provided in the housing 10. The guide rail 17 is provided with a plurality of slots 18 for limiting and fixing the anode plate 21. The anode plate 21 is fixed by the slots 18 to prevent the anode plate 21 from loosening.

[0039] The above specifically describes the preferred embodiments of the present invention, but the present invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of the present invention.
