[0030] During the vapor deposition process, the filter element can effectively intercept the metal organic compound particles carried by the gas and the solid impurities and polymers produced by the decomposition of these compounds at high temperatures to prevent them from contaminating the deposition layer. After long-term use, if the pollutants accumulated on the filter element reach saturation, the pollutants include dust impurities and some recyclable filter element particles. The traditional filter element cleaning method mainly relies on water washing, which not only produces a large amount of wastewater containing pollutants and increases additional costs, but also causes a waste of some recyclable filter element particles, which is not conducive to the conservation and utilization of resources. Therefore, the present disclosure provides a filter element cleaning device that can solve the problems existing in the prior art.

[0031] Example 1

[0032] The present disclosure provides a filter element cleaning device, such as Figure 1 As shown, it includes: a device body 1, a cleaning area 101 is provided inside the device body 1 for accommodating a filter element 12; at least two first cleaning brushes 2, the two first cleaning brushes 2 are relatively arranged in the cleaning area 101, and the two first cleaning brushes 2 can be distributed on both sides of the filter element 12 and contact the surface of the filter element 12; a first driving device 3, the first driving device 3 is used to connect the filter element 12 to drive the filter element 12 to rotate relative to the first cleaning brush 2; a collecting device 4, the collecting device 4 is arranged below the device body 1 in a vertical direction, the device body 1 is located below the cleaning area 101 and is also provided with a channel 103, and the collecting device 4 is connected to the cleaning area 101 through the channel 103; and a sealing device 5, the sealing device 5 includes a channel sealing plate 501 and a second driving device 502, the channel sealing plate 501 is arranged between the cleaning area 101 and the channel 103, and the second driving device 502 is connected to the channel sealing plate 501, and is used to drive the channel sealing plate 501 to rotate or slide relative to the channel 103 to conduct or block the channel 103.

[0033] The filter element cleaning device provided in the embodiment of the present disclosure is not only suitable for cleaning the surface of the filter element, but also suitable for various equipment and systems that require cleaning and filtering.

[0034] The device body 1 can be a box structure made of steel or engineering plastics, and its specific shape is not limited. A cleaning area 101 is provided inside the device body 1 for accommodating the filter element 12 to be cleaned. The internal space of the cleaning area 101 is designed according to the specifications of the filter element 12, leaving enough space for the filter element 12 to rotate and for the first cleaning brush 2 to contact the surface of the filter element 12.

[0035] At least two first cleaning brushes 2 are arranged opposite to each other in the cleaning area 101, and they can be distributed on both sides of the filter element 12 and contact the surface of the filter element 12. For example, four first cleaning brushes 2 are arranged, and the four first cleaning brushes 2 are circumferentially distributed on the circumference of the filter element 12. The first cleaning brush 2 can be made of wear-resistant material (such as polyurethane or nylon), and the shape is adapted to the contour of the filter element 12, and can be spiral, corrugated or other forms to enhance the cleaning effect.

[0036] The first driving device 3 is responsible for connecting the filter element 12 and driving it to rotate relative to the first cleaning brush 2. Through the rotation, the dirt or filter element particles on the surface of the filter element 12 can be effectively removed by the first cleaning brush 2.

[0037] The collecting device 4 is arranged below the device body 1 in the vertical direction. The device body 1 may be provided with a plurality of legs to support it above the collecting device 4. The collecting device 4 is used to collect filter element particles cleaned from the filter element 12. The collecting device 4 may be a collecting bucket, etc., and its specific structure is not limited. The device body 1 is provided with a channel 103 below the cleaning area 101. The collecting device 4 is connected to the cleaning area 101 through the channel 103 to ensure that the filter element particles can smoothly enter the collecting device 4 for collection.

[0038] The second driving device 502 is connected to the device body 1, and can be an electric push rod 9, a pneumatic cylinder or an electric valve, etc. By driving the channel sealing plate 501 to slide horizontally or flip vertically relative to the channel 103, the connection state between the cleaning area 101 and the collecting device 4 can be flexibly adjusted. When it is necessary to discharge the filter element particles, the channel sealing plate 501 can be opened to connect the cleaning area 101 with the collecting device 4. After the collection task is completed, the channel sealing plate 501 is closed to maintain the sealed environment of the cleaning area 101 to prevent pollution or leakage.

[0039] The filter element cleaning device provided in the embodiment of the present disclosure directly acts on the surface of the filter element 12 through the first cleaning brush 2 to clean it. This process abandons the traditional water washing method, thereby avoiding the consumption of water resources and the generation of a large amount of wastewater and sludge caused by cleaning agents, effectively reducing the pollution pressure on the environment, and eliminating the subsequent complex sewage treatment steps, greatly reducing the cleaning cost. The collection device 4 can ensure that the filter element particles that fall off during the cleaning process are completely collected, and these particles can then be sent to the outside for recycling and reuse, thereby not only realizing the recycling of resources, but also creating additional economic value for users.

[0040] In some embodiments, Figure 1 and Figure 2 As shown, the device body 1 is further provided with a collecting area 102, which is arranged between the cleaning area 101 and the channel 103, and the size of the cross-sectional area of ​​the collecting area 102 decreases from top to bottom along the vertical direction.

[0041] The cross-sectional area at the top entrance of the collection area 102 is relatively large, ensuring that the filter cartridge particles and impurities that fall off from the cleaning area 101 can enter smoothly. As it extends downward, the cross-sectional area gradually decreases, and the filter cartridge particles can be gradually concentrated during the descent process by utilizing the principle of gravity. The outlet of the collection area 102 is connected to the channel 103, and the channel sealing plate 501 is arranged between the collection area 102 and the channel 103. The fallen filter cartridge particles are first accumulated in the collection area 102 until the set quality threshold is reached, and then the channel sealing plate 501 is opened in a timely manner to safely introduce the accumulated filter cartridge particles into the final collection device 4 through the channel 103 at one time. In this way, the sealing state of the device body 1 can be maintained during the cleaning process, effectively preventing the environmental pollution caused by the leakage of the filter cartridge particles, and also avoiding the potential interference of the continuous accumulation of the filter cartridge particles on the cleaning efficiency.

[0042] In some embodiments, the filter element cleaning device also includes: a sensing device, which is connected to the channel sealing plate 501 and is used to detect the weight of the cleaned filter element particles; a control device, which is respectively connected to the sensing device and the second driving device 502 for communication, and the control device controls the start and stop of the second driving device 502 according to the detection information of the sensing device.

[0043] The sensing device may be a weight sensor, etc., connected to the channel sealing plate 501, and can sense the pressure change on the channel sealing plate 501 caused by the accumulation of filter element particles, and convert this physical change into an accurate electrical signal to transmit to the control device. The control device may be a simple relay, a programmable logic controller (PLC), a microprocessor or a complex computer control system.

[0044] When the filter particles accumulated on the channel sealing plate 501 reach the set weight, the sensing device transmits the information to the control device, which issues a command to activate the second driving device 502, thereby driving the channel sealing plate 501 to open, ensuring that the filter particles in the collection area 102 are smoothly discharged into the collection device 4 below at the best time. The whole process does not require manual intervention, which greatly improves the work efficiency and reduces the operation error and labor intensity.

[0045] In some embodiments, Figure 3As shown, the filter element cleaning device also includes: a plurality of second cleaning brushes 8, the plurality of second cleaning brushes 8 are evenly distributed on the inner wall surface of the collection area 102, and the second cleaning brushes 8 can slide along the inner wall surface.

[0046] The second cleaning brush 8 can be installed on a slide rail or a slide groove, and the slide rail or slide groove structure can be integrated with the inner wall of the collection area 102 to ensure that the second cleaning brush 8 can slide smoothly without affecting the sealing of the collection area 102. The material of the second cleaning brush 8 can also be made of wear-resistant materials, such as polyurethane or nylon, and the shape is adjusted according to the contour of the inner wall to ensure good contact and cleaning effects. The second cleaning brush 8 can be driven to slide along the inner wall by manual adjustment or by adding a small motor drive. Through the sliding action of the second cleaning brush 8 along the inner wall, fine particles or residues that may adhere to the inner wall during the collection process can be effectively removed, ensuring the cleanliness of the collection area 102, reducing the cleaning cycle, and effectively avoiding blockage of the collection area 102, ensuring smooth discharge of particulate matter, and maintaining efficient operation of the device.

[0047] In some embodiments, the cross-sectional area of ​​the collection area 102 is a trapezoid. The side walls of the trapezoidal structure can be designed to have a smooth transition or a guiding slope to help the filter element particles slide along the wall surface and accelerate their convergence to the bottom channel 103. There can be four corresponding second cleaning brushes 8, and each second cleaning brush 8 is designed to fit the inner wall of a collection area 102. Since the collection area 102 is a structure that is wide at the top and narrow at the bottom, the two ends of the second cleaning brush 8 along the length direction are designed to be flexible and deformable structures. So that when the cleaning brush slides downward along the trapezoidal wall, its two ends can follow the narrowing trend of the side walls of the collection area 102, and achieve a tight fit through flexible contact, whether at the wide top or at the narrow bottom, it can maintain effective cleaning contact, ensuring efficient cleaning from top to bottom, without omissions and dead angles, and significantly enhancing the cleaning ability of the collection area 102.

[0048] In some embodiments, Figure 3 As shown, the filter element cleaning device also includes: multiple push rods 9, which are slidably connected to the device body 1, one end of each push rod 9 extends into the collection area 102 and is connected to a second cleaning brush 8, and the other end is arranged outside the device body 1, and the second cleaning brush 8 is controlled to move along the inner wall surface of the collection area 102 by driving the push rod 9 to slide relative to the device body 1.

[0049] The length of the push rod 9 and the position of the second cleaning brush 8 can be adjusted according to the actual size and shape of the collection area 102. One end of the push rod 9 goes deep into the collection area 102 and is firmly connected to the second cleaning brush 8 through a mechanical connector (such as hinges, bolts, etc.) to ensure that the sliding of the push rod 9 can be accurately transmitted to the second cleaning brush 8, driving it to slide along the inner wall. The other end of the push rod 9 extends to the outside of the device body 1, which is convenient for manual drive or installation of a drive mechanism (such as a motor, a pneumatic cylinder, etc.) for control. The external operating end may be provided with a handle 903 or directly connected to the interface of the drive device to facilitate operation by an operator or an automatic control system. By externally driving the push rod 9, the second cleaning brush 8 can slide along the wall, so that the second cleaning brush 8 can be operated regularly or on demand to ensure that the inner wall of the collection area 102 remains clean.

[0050] In some embodiments, the push rod 9 includes a first rod portion 901 and a second rod portion 902 arranged along the length direction, one end of the second rod portion 902 is connected to the second cleaning brush 8, and the other end of the second rod portion 902 is rotatably connected to the first rod portion 901, so that the first rod portion 901 can rotate in a vertical direction relative to the second rod portion 902; wherein the rotating structure is arranged close to the second cleaning brush 8.

[0051] The push rod 9 is composed of two parts, namely the first rod part 901 and the second rod part 902, and the two parts are connected in sequence along the length direction of the push rod 9. The second rod part 902 is directly connected to the second cleaning brush 8, and the other end thereof can be rotatably connected to the first rod part 901 through a rotating shaft 6 or a hinge or similar structure, so as to ensure that the two sections of the rod can rotate relative to each other in the vertical direction. By arranging the rotating structure close to the second cleaning brush 8, and the first rod part 901 can rotate in the vertical direction relative to the second rod part 902 through the rotating structure, it can be achieved that when the collection area 102 is cleaned, the second cleaning brush 8 will return to the top of the collection area 102. At this time, the first rod part 901, the rotating structure and the second rod part 902 are all moved outside the device body 1. Under the action of gravity, the first rod part 901 naturally droops, thereby limiting the continued sliding of the second cleaning brush 8 and ensuring its stable positioning. When the cleaning procedure is started again, the operator only needs to simply lift the first rod 901 so that the two rods form a straight line. Then, through the linear advancement of the push rod 9, the second cleaning brush 8 can slide smoothly along the inner wall of the collection area 102 to perform the cleaning task.

[0052] In some embodiments, a through hole is provided on the side wall of the device body 1, and the push rod 9 passes through the through hole to connect with the second cleaning brush 8, and the range of the through hole is larger than the size of the cross-sectional area of ​​the push rod 9; it also includes: a sealing member, which is arranged at the through hole and is used to seal the gap between the push rod 9 and the through hole, and the sealing member is flexible.

[0053] The side wall of the device body 1 is provided with a plurality of through holes corresponding to the number of the push rods 9, and the diameter of the through holes is slightly larger than the cross section of the push rod 9, so that the push rod 9 can smoothly connect to the second cleaning brush 8 in the collection area 102, while ensuring the smooth movement of the push rod 9. A flexible seal is arranged around the through hole, such as a rubber ring or an elastic seal pad and other existing parts, which can tightly surround the interface between the push rod 9 and the through hole, so that during the cleaning operation, dust and filter particles can be effectively blocked from penetrating through the gap between the push rod 9 and the side wall, thereby ensuring the sealing of the device body 1 and the isolation effect of the cleaning area.

[0054] By adopting a flexible sealing design, the seal can still maintain a good sealing effect when the push rod 9 frequently enters and exits the through hole, ensuring effective isolation of the collection area 102 from the external environment. The flexibility of the seal also supports the unimpeded passage of the rotating structure between the first rod portion 901 and the second rod portion 902, ensuring that the rotating operation is not hindered.

[0055] In some embodiments, the filter element cleaning device also includes: a rotating shaft 6, which is horizontally arranged in the cleaning area 101, and the filter element 12 can be sleeved on the rotating shaft 6 and connected to the rotating shaft 6; a transmission assembly 7, and the first drive device 3 is connected to the rotating shaft 6 through the transmission assembly 7 to drive the rotating shaft 6 to rotate.

[0056] The rotating shaft 6 is horizontally placed in the cleaning area 101 to provide a rotating fulcrum for the filter element 12. The rotating shaft 6 can be adapted to the filter element 12 so that the filter element 12 can be easily sleeved on the rotating shaft 6. At the same time, the filter element 12 can be firmly connected to the rotating shaft 6 through a fixing device (such as a locking ring, a threaded connection, etc.), ensuring that the filter element 12 and the rotating shaft 6 rotate synchronously during the rotation process without slipping. The side wall of the device body 1 has a built-in bearing, which is precisely docked with the rotating shaft 6, which not only supports the stable operation of the rotating shaft 6, but also reduces friction loss. One end of the rotating shaft 6 extends out of the device body 1 and is connected to the transmission component 7. The transmission component 7 serves as a bridge between the first drive device 3 and the rotating shaft 6, and is responsible for efficiently and accurately transmitting the rotational power of the first drive device 3 to the rotating shaft 6. It may include mechanical transmission components such as a gear set, a pulley and a belt, a chain and a sprocket. The rotating shaft 6 drives the filter element 12 to rotate and cooperates with the movement of the first cleaning brush 2, so as to achieve all-round and dead-angle cleaning of the surface of the filter element 12, and significantly improve the cleaning efficiency and cleaning quality.

[0057] In some embodiments, a switch door 11 may be connected to one side of the device body 1, and the filter element 12 can be placed into the cleaning area 101 of the device body 1 through the switch door 11. When closed, the switch door 11 can be sealed and connected to the device body 1 through existing structures such as door locks.

[0058] In some embodiments, the collecting device 4 is provided with an opening on one side facing the device body 1, and the range of the opening is larger than the cross-sectional area of ​​the channel 103; and further comprising: a lifting device 10, such as Figure 2 As shown, the lifting device 10 is vertically arranged below the device body 1 , and is used to drive the collecting device 4 to approach or move away from the device body 1 , so that the channel 103 can extend into the collecting device 4 or be separated from the collecting device 4 .

[0059] An opening is provided on one side of the collecting device 4 facing the device body 1, and its size is larger than the cross-sectional area of ​​the channel 103, so as to ensure that the channel 103 has enough space when extending into or out of the collecting device 4, thereby avoiding unnecessary friction or obstruction. The lifting device 10 located below the device body 1 is arranged in the vertical direction, and an electric lifting platform, hydraulic or pneumatic cylinder, etc. can be used as an actuator. The lifting surface of the lifting device 10 is used to place the collecting device 4. By moving up and down, the collecting device 4 can be brought close to the device body 1 when needed, so that the channel 103 can be smoothly inserted into the collecting device 4; and in the non-cleaning stage or maintenance, the collecting device 4 can be lifted and separated from the device body 1, so as to facilitate emptying the collected filter element particles or cleaning and maintenance.

[0060] The passage 103 can extend into the collecting device 4, which can reduce the possibility of leakage of filter element particles during the cleaning process, effectively prevent pollution of the working environment, and improve environmental protection performance.

[0061] The filter element cleaning device provided by the present disclosure can abandon the traditional water washing method, avoid the consumption of water resources and the generation of a large amount of wastewater and sludge, effectively reduce the pollution pressure on the environment, and save the subsequent complex sewage treatment steps, greatly reducing the cleaning cost. At the same time, the filter element particles that fall off during the cleaning process can be completely collected and recycled, realizing the recycling of resources and creating additional economic value for users.
