Description

Technical Field

[0001] This application relates to the field of filter element cleaning in low-pressure diffusion furnaces, and more particularly to a filter element cleaning tank. Background Technology

[0002] Low-pressure diffusion furnaces are widely used in the semiconductor and photovoltaic industries. The filter element is a key component of this furnace, removing impurities, particulate matter, organic matter, and microorganisms from gases or fluids through physical and chemical processes to ensure the quality of silicon wafers. As the low-pressure diffusion furnace is used over time, dirt and blockages accumulate in the filter element, leading to decreased filtration efficiency and even affecting the normal operation of the furnace. Therefore, regular cleaning of the filter element is essential to maintain its filtration performance and extend the lifespan of the low-pressure diffusion furnace.

[0003] However, existing filter cleaning processes typically involve immersing the filter in a cleaning solution, combined with manual scrubbing. After cleaning, the filter needs to air dry, which is greatly affected by weather and environmental factors and is slow. Furthermore, the entire process—immersion, scrubbing, and drying—requires manual operation, increasing labor costs and reducing filter cleaning efficiency. Utility Model Content

Detailed Implementation

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] In this application, the terms "upper," "inner," "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0032] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0033] Furthermore, the terms "installation," "setup," "equipped with," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0034] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0035] Low-pressure diffusion furnaces are widely used in the semiconductor and photovoltaic industries. The filter element is a key component of this furnace, removing impurities, particulate matter, organic matter, and microorganisms from gases or fluids through physical and chemical processes to ensure the quality of silicon wafers. As the low-pressure diffusion furnace is used over time, dirt and blockages accumulate in the filter element, leading to decreased filtration efficiency and even affecting the normal operation of the furnace. Therefore, regular cleaning of the filter element is essential to maintain its filtration performance and extend the lifespan of the low-pressure diffusion furnace.

[0036] However, existing filter cleaning processes require the filter to air dry after cleaning. This natural drying method is highly susceptible to weather and environmental factors and is relatively slow. In humid or rainy weather, the filter may not dry in time, increasing the risk of mold growth and affecting its hygiene and filtration efficiency. This can lead to clogging or decreased filtration efficiency during subsequent use, resulting in shorter maintenance cycles and increased replacement frequency and costs. Furthermore, the entire process, including soaking, washing, and drying, requires manual operation, increasing labor costs and reducing the cleaning efficiency of the filter.

[0037] To address the aforementioned issues, this application further improves upon existing filter element cleaning devices by designing a filter element cleaning tank.

[0038] Based on this, this application discloses a filter element cleaning tank that ensures the filter element is completely immersed in the cleaning solution during cleaning and enables the filter element to dry after the cleaning process is completed, thereby improving the efficiency of the filter element cleaning and drying processes and reducing labor costs.

[0039] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0040] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the filter element 200 disclosed in the embodiments of this application. Figure 2This is one of the structural schematic diagrams of a filter element 200 installed in a filter element cleaning tank 100 as disclosed in an embodiment of this application. This application discloses a filter element cleaning tank 100, a tank body 01 including a cleaning chamber 101; a cleaning pipe 02 for connecting to a cleaning medium supply device, which can provide cleaning gas and / or cleaning solution to the cleaning pipe 02; a spray mechanism 03 connected to the cleaning pipe 02, the spray mechanism 03 including multiple spray pipes 301, the spray pipes 301 passing through the tank body 01 and extending into the cleaning chamber 101, the spray pipes 301 having multiple spray holes 301a, the spray pipes 301 supporting the filter element 200 so that the filter element 200 is fitted onto the outside of the spray pipes 301; and a liquid outlet pipe 04 passing through the tank body 01 and communicating with the cleaning chamber 101.

[0041] The tank body 01 is the basic structure of the filter element cleaning tank 100. The tank body 01 is equipped with a cleaning chamber 101, which is used to contain the cleaning solution, filter element 200, and spray pipe 301, etc. The tank body 01 provides a stable and reliable environment for the cleaning process of filter element 200, thereby ensuring that the cleaning process of filter element 200 can be carried out stably.

[0042] Optionally, the tank body 01 can be made of polypropylene, which is not easily corroded by most chemicals such as acids, alkalis, and salts. Even if the tank body 01 is in contact with the cleaning solution for a long time, it can maintain the stability of the physical and chemical properties of the tank body 01.

[0043] A cleaning medium supply device is installed outside the tank 01, which can provide cleaning solution or cleaning gas. During the cleaning process, the cleaning solution is used to soak and rinse the filter element 200, causing impurities on the filter element 200 to react with the cleaning solution and be removed. The cleaning medium supply device can simultaneously supply cleaning liquid and cleaning gas to the cleaning chamber 101. The cleaning gas is used to form bubbles or eddies during the soaking process to accelerate the reaction efficiency between impurities and the cleaning solution. Alternatively, the cleaning medium supply device can first supply cleaning liquid into the cleaning chamber 101, and when the cleaning liquid reaches the target level, then inject cleaning gas into the cleaning chamber 101 to use bubbles or eddies to remove impurities from the filter element 200.

[0044] Optionally, the cleaning solution can be a liquid containing chemicals such as acids, alkalis, and salts, such as chemicals, solutions, or suspensions, used to react with impurities on the filter element 200 to remove them. The cleaning solution can also be water. The cleaning gas can be clean air, nitrogen, etc.

[0045] After the cleaning process is completed, the filter element 200 undergoes a drying process in the cleaning chamber 101. The cleaning medium supply equipment can stop supplying cleaning solution to the cleaning chamber 101 and supply cleaning gas instead. The cleaning gas is used to accelerate the drying of the cleaning solution remaining on the surface of the filter element 200, preventing the filter element 200 from becoming damp for a long time, which would lead to a decrease in filtration efficiency.

[0046] The filter element cleaning tank 100 also includes a cleaning pipe 02, which can deliver the cleaning solution or cleaning gas provided by the cleaning medium supply equipment from the cleaning chamber 101 outside the tank body 01, so that the filter element 200 in the cleaning chamber can react with the cleaning solution or cleaning gas, ensuring the effectiveness of the filter element 200 in the cleaning and drying processes.

[0047] Alternatively, to avoid occupying space in the cleaning chamber 101, the cleaning pipe 02 can be located outside the tank 01.

[0048] Specifically, the cleaning pipeline 02 may include a pipeline for conveying the cleaning solution and a pipeline for conveying the cleaning gas, or the cleaning solution and the cleaning gas may be transported from the same cleaning pipeline 02. The layout of the cleaning pipeline 02 can be determined according to the space and needs during actual production.

[0049] Optionally, the cleaning pipe 02 can be made of materials such as polypropylene or stainless steel that are not easily corroded by most chemicals such as acids, alkalis, and salts. This embodiment does not limit this.

[0050] A spray mechanism 03 is installed inside the cleaning chamber 101, and the spray mechanism 03 is connected and communicates with the cleaning pipe 02. The spray mechanism 03 may include multiple cleaning pipes, each of which is connected to the cleaning pipe 02. The cleaning pipe 02 delivers the cleaning solution or cleaning gas supplied by the cleaning medium supply equipment into the spray pipe 301, and then the spray pipe 301 delivers the cleaning solution or cleaning gas into the cleaning chamber 101.

[0051] The filter element 200 that needs cleaning can be fitted over the spray pipe 301. The spray pipe 301 provides support and a certain degree of fixation for the filter element 200, preventing it from moving in the cleaning solution due to its flow and affecting the reaction between impurities and the cleaning solution during the cleaning process. The number of spray pipes 301 in the spray mechanism 03 can be determined according to the actual production needs.

[0052] The spray pipe 301 is provided with multiple spray holes 301a, which can spray the cleaning solution or cleaning gas inside the spray pipe 301 into the cleaning chamber 101. The filter element 200 is sleeved on the spray pipe 301, so that the cleaning solution or cleaning gas sprayed from the spray holes 301a can first contact the filter element 200 and then penetrate the filter element 200 into the cleaning chamber 101. The cleaning solution or cleaning gas first contacts and reacts with the surface of the filter element 200 before entering the cleaning chamber 101, which can ensure that the cleaning solution or cleaning liquid reacts with the impurities on the surface of the filter element 200 first. At the same time, when the cleaning solution or cleaning liquid is sprayed out from the spray holes 301a, it forms one or more jets, which can directly impact the impurities on the surface of the filter element 200. The jetting airflow can replace manual brushing, allowing the impurities to fall off the surface of the filter element 200 and fall into the cleaning chamber 101 more quickly.

[0053] Optionally, the cleaning pipe 02 may be equipped with a pressure regulating device to prevent the cleaning solution or cleaning gas transported by the cleaning pipe 02 from being too high, which could cause the cleaning solution or cleaning gas to spray out of the spray hole 301a at too high a flow rate, thereby damaging the filter element 200 and affecting its subsequent use.

[0054] The filter element cleaning tank 100 also includes a liquid outlet pipe 04, which passes through the tank body 01 and connects to the cleaning chamber 101. The liquid outlet pipe 04 discharges the cleaning solution from the cleaning chamber 101 after the cleaning process of the filter element 200 is completed, ensuring that the filter element 200 is no longer immersed in the reacted cleaning solution and preventing damage to the filter element 200 caused by excessive reaction between the cleaning solution and the filter element 200. Simultaneously, discharging the cleaning solution from the cleaning chamber 101 ensures the subsequent drying process of the cleaning chamber 101, allowing the filter element 200 to complete its drying process within the emptied cleaning chamber 101.

[0055] Optionally, the outlet pipe 04 can be made of materials such as polypropylene or stainless steel that are not easily corroded by most acids, alkalis, salts and other chemicals. This embodiment does not limit this.

[0056] Optionally, the contact surface between the outlet pipe 04 and the tank body 01 can be provided with a sealing structure (e.g., sealing ring, flange seal, and thread seal) to prevent the cleaning solution after reacting with impurities on the filter element 200 from leaking between the outlet pipe 04 and the tank body 01.

[0057] Thus, the filter element cleaning tank 100 provided in this embodiment can fully immerse the filter element 200 in the cleaning solution during the cleaning process, and improve the cleaning efficiency of the filter element 200 by conveying cleaning gas. After the cleaning process is completed, there is no need to transfer the filter element 200 from the filter element cleaning tank 100. After the used cleaning solution is discharged from the filter element cleaning tank 100, cleaning gas is then conveyed through the cleaning pipe 02 to assist in drying the filter element 200, thereby completing the drying process of the filter element 200 and improving the drying efficiency of the filter element 200. At the same time, both the cleaning and drying processes of the filter element 200 are automated, which improves the cleaning efficiency of the filter element 200 and saves labor costs.

[0058] Please see Figure 2 As an optional implementation, the cleaning pipe 02 includes: a liquid inlet pipe 201, which is used to connect to the cleaning solution in the cleaning medium supply equipment; and an air inlet pipe 202, the first end of which is connected to the air inlet pipe 202, and the second end of which is used to connect to the cleaning gas in the cleaning medium supply equipment.

[0059] The cleaning pipeline 02 includes a liquid inlet pipe 201 and an air inlet pipe 202. The liquid inlet pipe 201 is connected to the cleaning medium supply equipment. The liquid inlet pipe 201 can deliver the cleaning solution supplied by the cleaning medium supply equipment to the spray pipe 301, and then the spray pipe 301 delivers it into the cleaning chamber 101, thereby completing the process of the cleaning solution entering the cleaning chamber 101.

[0060] Optionally, in order to prevent impurities in the cleaning solution from entering the cleaning chamber 101 and causing secondary pollution to the filter element 200, a filter or purification device can also be installed on the inlet pipe 201 to remove suspended solids, particulate matter and other impurities in the cleaning solution and ensure the purity of the cleaning solution.

[0061] The first end of the air inlet pipe 202 is connected to the liquid inlet pipe 201, and the second end of the air inlet pipe 202 is connected to the cleaning medium supply equipment. The air inlet pipe 202 delivers the cleaning gas supplied by the cleaning medium supply equipment to the liquid inlet pipe 201, and then through the liquid inlet pipe 201 it is delivered into the spray pipe 301 and thus into the cleaning chamber 101. This ensures that the cleaning solution and cleaning gas are blown onto the filter element 200 simultaneously, thereby improving the cleaning efficiency of the filter element 200.

[0062] Optionally, in order to prevent impurities in the cleaning gas from entering the cleaning chamber 101 and causing secondary pollution to the filter element 200, a filter or purification device can also be installed on the air inlet pipe 202 to remove dust and other impurities in the cleaning gas and ensure the purity of the cleaning gas.

[0063] Please see Figure 2As an optional implementation, the filter element cleaning tank 100 further includes: a liquid inlet valve 2011, which is disposed on the liquid inlet pipe 201 and is located outside the tank body 01; and an air inlet valve 2021, which is disposed on the air inlet pipe 202. The air inlet valve 2021 can be in the open state at the same time as the liquid inlet valve 2011, and the air inlet valve 2021 can also be in the open state when the liquid inlet valve 2011 is closed.

[0064] The inlet valve 2011 is installed on the inlet pipe 201 and is used to control the flow of cleaning solution from the cleaning medium supply equipment to the cleaning chamber 101. When the cleaning process of filter element 200 needs to be started, the inlet valve 2011 is opened, and the cleaning solution can enter the spray pipe 301 through the inlet pipe 201 and finally be sprayed onto the filter element 200. When the cleaning solution fills the cleaning chamber 101, the inlet valve 2011 is closed to stop the delivery of the cleaning solution and allow the filter element 200 to be fully immersed in the cleaning solution in the cleaning chamber 101.

[0065] An air inlet valve 2021 is installed on the air inlet pipe 202 to control the flow of cleaning gas from the cleaning medium supply equipment to the cleaning chamber 101. The liquid inlet valve 2011 can be opened simultaneously with the air inlet valve 2021, allowing the cleaning solution and cleaning gas to be sprayed onto the filter element 200 simultaneously, improving the cleaning efficiency of the filter element 200. The air inlet valve 2021 can also be opened independently when the liquid inlet valve 2011 is closed. In this case, the cleaning gas is sprayed into the cleaning solution in the tank 01, generating bubbles or eddies within the cleaning solution. This increases the frequency of flow between the cleaning solution and the filter element 200, allowing the cleaning solution to fully react with impurities on the filter element 200, achieving a brushing effect on the filter element 200. Alternatively, during the drying process of the filter element 200, opening the air inlet valve 2021 independently to spray cleaning gas onto the filter element 200 can accelerate the evaporation of the cleaning solution on the surface of the filter element 200, improving the drying efficiency of the filter element 200.

[0066] In some embodiments, the filter element cleaning tank 100 further includes a liquid outlet valve 401, which is disposed on the liquid outlet pipe 04 and is used to control the discharge of cleaning solution from the cleaning chamber 101. After the cleaning process in the cleaning chamber 101 is completed, the liquid inlet valve 2011 and the air inlet valve 2021 are closed and the liquid outlet valve 401 is opened, allowing the clean solution that has undergone reaction in the cleaning chamber 101 to flow out of the cleaning chamber 101 from the liquid outlet pipe 04. After the cleaning solution in the cleaning chamber 101 is completely discharged, the air inlet valve 2021 is opened, and cleaning gas is delivered into the spray pipe 301. The cleaning gas is sprayed from the spray holes 301a on the spray pipe 301 into the interior of the filter element 200, accelerating the evaporation of the residual cleaning solution on the filter element 200 and helping to improve the efficiency of the drying process of the filter element 200.

[0067] Please see Figure 3 , Figure 3This is one of the structural schematic diagrams of the filter element cleaning tank 100 disclosed in the embodiments of this application. As an optional implementation, there are multiple cleaning pipes 02, which are arranged at intervals along the length or width direction of the tank body 01; multiple spraying mechanisms 03 are provided corresponding to the multiple cleaning pipes 02, and each cleaning pipe 02 is connected to a spraying mechanism 03.

[0068] The filter element cleaning tank 100 is equipped with multiple cleaning pipes 02, each of which is connected to a spray structure. That is, each cleaning pipe 02 is connected to multiple spray pipes 301, thereby increasing the number of spray pipes 301 in the filter element cleaning tank 100. The number of filter elements 200 that can be cleaned and dried in the filter element cleaning tank 100 corresponds to the number of spray pipes 301, thereby increasing the number of filter elements 200 that can be processed in one filter element 200 cleaning and drying process, thus achieving the purpose of improving the cleaning and drying efficiency of filter elements 200.

[0069] Please see Figure 4 , Figure 4 This is a second schematic diagram of the filter element cleaning tank 100 disclosed in this application. As an optional implementation, the spray pipe 301 extends along the height direction of the tank body 01, and a plurality of spray holes 301a are arranged at intervals along the height direction of the tank body 01. The plurality of spray holes 301a located at the same height are arranged at intervals along the circumference of the spray pipe 301.

[0070] The spray pipe 301 extends along the height direction of the tank 01, which can make fuller use of the space inside the tank. The reasonable arrangement of the spray pipe 301 increases the number of spray pipes 301 that can be accommodated in the tank, thereby improving the efficiency of the cleaning and drying process of the filter element 200.

[0071] Multiple spray holes 301a are arranged at intervals along the height direction of the tank 01. Multiple spray holes 301a located at the same height are arranged at intervals along the circumference of the spray pipe 301, so that multiple spray holes 301a are evenly arranged on the surface of the filter element 200 facing the spray pipe 301. This allows the interior of the filter element 200 to come into more uniform contact with the cleaning solution or cleaning gas sprayed from the spray holes 301a, thereby ensuring that the impurities on the filter element 200 can react more fully with the cleaning solution, or that the residual cleaning solution on the filter element 200 can evaporate more fully, thus ensuring the cleaning and drying effects of the filter element 200 cleaning and drying process.

[0072] Please see Figure 5 , Figure 5 This is a schematic diagram of the structure of the pressure plate 05 disclosed in an embodiment of this application. As an optional implementation, the filter element cleaning tank 100 includes: a pressure plate 05, which is detachably connected to the tank body 01, and the pressure plate 05 and the free end of the spray pipe 301 are spaced apart along the height direction of the tank body 01.

[0073] The main function of the pressure plate 05 is to limit the position of the filter element 200. Since the filter element 200 is immersed in the cleaning solution, its buoyancy causes it to easily drift and detach from the spray pipe 301. The pressure plate 05 applies downward pressure to the filter element 200 by its own weight, ensuring that the filter element 200 is stably fitted onto the spray pipe 301 during the cleaning process, and will not rise or drift and detach from the spray pipe 301 due to buoyancy. This ensures that the cleaning solution can be sprayed onto the filter element 200 fully and evenly.

[0074] Please see Figure 6 and Figure 7 , Figure 6 This is the third schematic diagram of the filter cleaning tank 100 disclosed in the embodiments of this application. Figure 7 This is a second schematic diagram of the filter element 200 installed in the filter element cleaning tank 100 according to an embodiment of this application. As an optional implementation, the filter element cleaning tank 100 includes: a mounting part 102, disposed on the inner wall of the tank body 01, the mounting part 102 extending along the height direction of the tank body 01, and a limiting part formed on the side of the mounting part 102 near the bottom wall 103 of the tank body 01; and a mating part 501, formed on the edge of the pressure plate 05, the limiting part slidingly engaging with the mounting part 102 and being detachably connected, the mating part 501 being able to limit the engagement with the limiting part to position the pressure plate 05 in the tank body 01, so that the pressure plate 05 and the free end of the spray pipe 301 have a gap along the height direction of the tank body 01.

[0075] The mounting part 102 is provided on the inner wall of the tank 01 and extends along the height direction of the tank 01 until it penetrates the opening end of the tank 01, so that the pressure plate 05 can be installed and removed on the tank 01 through the mounting part 102. At the same time, the mounting part 102 provides a certain guiding function for the installation of the pressure plate 05.

[0076] Optionally, the mounting part 102 can be in the form of a slot, a slide rail, etc., and this application does not limit it in this way.

[0077] The mounting part 102 forms a limiting part on the side of the bottom wall 103 of the tank body 01 near the tank body 01. The limiting part is located at the target position of the tank body 01 so that the limiting part positions the pressure plate 05 at the target height of the tank body 01, so as to avoid the spray pipe 301 from colliding or interfering with the pressure plate 05 when installing and removing the pressure plate 05.

[0078] The pressure plate 05 has a mating portion 501 formed on its periphery. The mating portion 501 is used for sliding engagement with the mounting portion 102 and for limiting engagement with the limiting portion. The mating portion 501 can slide relative to the mounting portion 102 along the height direction of the tank 01 to enter the cleaning chamber 101, and is limited by the limiting portion after sliding a distance from the mounting portion 102.

[0079] Optionally, the mating part 501 can be in the form of a limiting protrusion, a limiting groove, or the like.

[0080] As an optional implementation, the mounting part 102 is configured as a mounting groove, which extends along the height direction of the groove body 01 and penetrates the opening end of the groove body 01. The groove opening faces the cleaning chamber 101, and the limiting part is the limiting bottom wall of the mounting groove.

[0081] The mounting part 102 is configured as a mounting groove, which matches the mating part 501 on the edge of the pressure plate 05. During installation, simply align the mating part 501 of the pressure plate 05 with the mounting groove and push it in to complete the installation. The mating groove and the mating part 501 of the pressure plate 05 facilitate simple installation and make it easy to replace or adjust the pressure plate 05. At the same time, the mounting groove provides a guiding function for the installation of the pressure plate 05, reducing errors during the installation process.

[0082] Please see Figure 5 As an optional implementation, the pressure plate 05 is provided with a plurality of liquid permeation holes 502, which penetrate the pressure plate 05 along the height direction of the tank body 01.

[0083] The liquid permeation hole 502 allows the cleaning solution in the cleaning chamber 101 to overflow above the pressure plate 05 when it reaches a certain level. This allows the operator to determine if the cleaning chamber 101 is full by observing whether cleaning solution overflows above the pressure plate 05, ensuring that the filter element 200 is fully immersed in the cleaning solution. Simultaneously, the inlet valve 2011 can be closed when a certain amount of cleaning solution is reached to stop the delivery of cleaning solution and prevent waste due to excessive cleaning solution in the cleaning chamber 101.

[0084] Please see the return Figure 2 As an optional implementation, the filter element cleaning tank 100 further includes: a mounting hole 603a disposed on the bottom wall 103 of the tank body 01; a receiving tank 06 connected to the bottom wall 103 of the tank body 01, the receiving tank 06 including an isolation cavity 601, the cleaning pipe 02 passing through the receiving tank 06 and extending into the isolation cavity 601, the spray pipe 301 passing through the mounting hole 603a and extending into the isolation cavity 601 to be connected to the cleaning pipe 02, and the spray hole 301a located on the side of the bottom wall 103 of the tank body 01 opposite to the cleaning pipe 02.

[0085] The receiving tank 06 is connected to the bottom wall 103 of the tank body 01, and the receiving tank 06 includes an isolation chamber 601. The isolation chamber 601 provides an independent space for the cleaning pipe 02. By placing the cleaning pipe 02 in the isolation chamber 601 outside the tank body 01, the space of the cleaning chamber 101 is reduced, thereby reducing the amount of cleaning solution required to clean the filter element 200, thus achieving the purpose of saving cleaning solution and reducing the cleaning cost of the filter element 200.

[0086] Meanwhile, the cleaning pipe 02 is located inside the isolation chamber 601 and is not directly exposed to the cleaning solution and impurities in the cleaning chamber 101, thus protecting the cleaning pipe 02 from corrosion by the cleaning solution or impurities on the filter element 200 and extending the service life of the cleaning pipe 02.

[0087] Optionally, the receiving groove 06 and the groove body 01 can be an integral structure or set separately; this embodiment does not limit this.

[0088] Mounting hole 603a is provided on the bottom wall 103 of tank body 01 to allow spray pipe 301 to pass through mounting hole 603a and extend into cleaning chamber 101, thereby introducing cleaning solution and cleaning gas into cleaning chamber 101 to contact filter element 200. Spray pipe 301 extends into cleaning chamber 101 through mounting hole 603a and is connected to cleaning pipe 02. Spray hole 301a is located inside cleaning chamber 101, which is separated from isolation chamber 601, thus ensuring that cleaning solution can smoothly enter cleaning chamber 101 and will not enter isolation chamber 601.

[0089] Please see Figure 2 As an optional implementation, the bottom wall 103 of the tank body 01 is provided with a liquid outlet 601a, and the liquid outlet pipe 04 is connected to the liquid outlet 601a; the side wall of the accommodating tank 06 is provided with an installation port 602a, which is connected to the isolation chamber 601, and the liquid outlet pipe 04 extends to the outside of the accommodating tank 06 through the installation port 602a.

[0090] The outlet 601a is located on the bottom wall 103 of the tank body 01, allowing the cleaning solution after the reaction between the filter element 200 and the impurities in the isolation chamber 601 to be completely discharged from the outlet 601a, thus avoiding impurity residue. Simultaneously, the discharge of the cleaning solution from the outlet 601a ensures that the interior of the cleaning chamber 101 remains dry during the drying process. The outlet pipe 04 is connected to the outlet 601a, ensuring that liquid can be discharged from the cleaning chamber 101 along the outlet pipe 04 without entering the interior of the isolation chamber 601.

[0091] Optionally, the contact surface between the outlet pipe 04 and the bottom wall 103 of the tank body 01 can be provided with a sealing structure (e.g., sealing ring, flange seal, and thread seal) to prevent the cleaning solution after reacting with impurities on the filter element 200 from leaking into the isolation chamber 601 between the outlet pipe 04 and the bottom wall 103 of the tank body 01.

[0092] The mounting port 602a is located on the side wall of the receiving tank 06 and communicates with the isolation chamber 601. The mounting port 602a provides a passage for the outlet pipe 04 to the interior of the isolation chamber 601, allowing the outlet pipe 04 to connect to the outlet port 601a on the bottom wall 103 of the tank body 01, thus facilitating the discharge of the cleaning solution from the cleaning chamber 101. Simultaneously, the mounting port 602a allows for easy installation and removal of the outlet pipe 04, and also facilitates maintenance and inspection of the interior of the isolation chamber 601.

[0093] As an optional implementation, the filter cleaning tank 100 further includes a sealing element disposed between the spray pipe 301 and the mounting hole 603a.

[0094] A seal is installed between the spray pipe 301 and the mounting hole 603a to ensure a good seal at the connection between the spray pipe 301 and the mounting hole 603a, preventing the cleaning solution from leaking into the isolation chamber 601 during the cleaning process. This maintains a stable level of the cleaning solution in the cleaning chamber 101, thus ensuring the stability of the cleaning process. It also prevents the cleaning solution from entering the isolation chamber 601.

[0095] The seal can also effectively prevent impurities in the isolation chamber 601 from entering the spray pipe 301 or the cleaning chamber 101, thereby ensuring that the cleaning chamber 101 is not contaminated, so as to ensure that the filter element 200 is not subject to secondary contamination during the cleaning and drying processes.

[0096] The spray pipe 301 may encounter vibrations and impacts during the cleaning process. The sealing element can provide sufficient sealing force and stability to ensure that the spray pipe 301 remains in a fixed position within the mounting hole 603a and will not loosen or fall off due to vibrations caused by the flow of the cleaning solution.

[0097] Optionally, the material of the seal can be rubber, silicone, polytetrafluoroethylene, etc., and this embodiment does not limit this.

[0098] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
