Description

Technical Field

[0001] This application relates to the technical field of filters, and in particular to a flip-type filter. Background Technology

[0002] A filter is a device used to separate solids and liquids. It works by separating solid particles from liquids through a filter medium (such as filter cloth or filter paper), and is widely used in industries such as chemical, pharmaceutical, and food processing.

[0003] In existing filters, multiple filter elements are usually installed inside. When liquid enters the filter, solid particles in the liquid that are smaller than the pore size of the filter elements will be filtered and intercepted by multiple filter elements, allowing the liquid to continue to be transported to the next device, while the solid particles will remain in the filter.

[0004] However, during filter use, solid particles are easily trapped by the filter element's pores. When liquid flows through the filter element, it squeezes and impacts the trapped solid particles, causing them to adhere tightly to the filter element's surface. As more and more solid particles adhere to the filter element's surface, the filter pressure increases. When the filter pressure reaches a preset value, the filter element needs to be cleaned or even replaced. However, cleaning existing filter elements usually requires large-scale disassembly of pipes and filter elements, which is complex and inefficient.

[0005] Therefore, there is an urgent need to improve existing filters. Summary of the Invention

[0006] This application provides a flip-type filter, which can effectively and conveniently facilitate the cleaning of filter elements by workers, and also facilitate the disassembly and replacement of filter elements by workers.

[0007] This application provides a flip-type filter, which adopts the following technical solution: A flip-type filter includes a housing, multiple filter elements, and a base. The housing includes a first outer shell, a second outer shell, and a partition; the first outer shell and the second outer shell are respectively disposed on both sides of the partition; a liquid outlet cavity is formed between the first outer shell and the partition and the first outer shell has a water outlet pipe communicating with the liquid outlet cavity; a filter cavity is formed between the second outer shell and the partition and the second outer shell has a water inlet pipe communicating with the filter cavity. The filter element is disposed on the partition plate and is entirely located in the filtration chamber, and multiple filter elements are evenly distributed on the partition plate; the filter element includes a core body and multiple filter elements; the core body has a first cavity inside and multiple first filter holes distributed on the outside, which communicate with the first cavity, and the end of the first cavity near the partition plate communicates with the liquid outlet chamber; the filter element is disposed on the outside of the core body, forming a second cavity between it and the core body and having multiple second filter holes distributed thereon, the second cavity communicating with the first cavity through the first filter holes and with the filtration chamber through the second filter holes; The base includes a frame; the housing is rotatably connected to the frame, and its rotation axis is perpendicular to the axis of the housing.

[0008] By adopting the above technical solution, when the filter element needs to be cleaned by removing sludge, the housing can be rotated to a horizontal position, and cleaning water can be poured into the housing through the outlet pipe so that the cleaning water can be discharged from the inlet pipe. During this process, the water flow can effectively clear the first and second filter holes, and the solid particles can be helped to leave the filter element under their own gravity. Afterwards, the housing can be rotated to an inverted position, and cleaning water can be poured into the housing through the inlet pipe so that the cleaning water can be discharged from the outlet pipe. The water flow can drive the solid particles remaining inside the filter element to be discharged. This can effectively and conveniently facilitate the staff to clean the filter element by removing sludge. Furthermore, when the filter element needs to be disassembled and replaced, the housing can be rotated to a suitable position so that the staff can easily disassemble and replace the filter element.

[0009] Optionally, the base may further include a first driving member; The first driving member is disposed on the frame and is used to drive the housing to rotate relative to the frame.

[0010] By adopting the above technical solution, staff can easily control the rotation of the housing according to their needs, while freeing up their hands to clean or replace the filter element, saving manpower and reducing the difficulty of operation.

[0011] Optionally, the base may further include a base and a second drive member; The frame is movably connected to the base, and its direction of movement is horizontal and perpendicular to the rotation axis of the housing; the second driving member is disposed on the base and is used to drive the frame to move relative to the base.

[0012] By adopting the above technical solution, it is possible for staff to keep the housing away from the original connected pipe when cleaning or replacing the filter element, which facilitates the rotation and adjustment of the housing and provides more operating space for staff, reducing the probability of damage to the filter or injury to staff caused by structural collisions during operation.

[0013] Optionally, the housing further includes two connecting pipes; the two connecting pipes are respectively movably connected to the water inlet pipe and the water outlet pipe, and the movement direction of the two connecting pipes is parallel to the extension direction of the water inlet pipe and the water outlet pipe, respectively.

[0014] By adopting the above technical solution, it is possible to easily connect the filter and the pipeline, and it is also easy to move away and rotate the filter after disconnecting it from the pipeline, reducing the probability of the filter being damaged by bumps during this process.

[0015] Optionally, the housing further includes two sealing rings, and the two sealing rings are respectively sleeved on the outside of the water inlet pipe and the water outlet pipe; the ends of the water inlet pipe and the water outlet pipe have raised edges, the sealing rings contact and abut against the raised edges, and the inner side of the connecting pipe has an abutment portion for contacting the sealing rings; When the connecting pipe moves to its limit position in the direction close to the partition, the adjacent sealing ring is exposed; when the connecting pipe moves to its limit position in the direction away from the partition, the abutting part contacts the sealing ring, and the connecting pipe is used to connect and communicate with the pipeline; during the process of the connecting pipe connecting and communicating with the pipeline, the sealing ring is squeezed between the abutting part and the protrusion.

[0016] By adopting the above technical solution, when the filter is connected to the pipeline, the sealing ring can effectively ensure the sealing of the connection under the state of compression; when the filter is disconnected from the pipeline, the sealing ring can be exposed so that the staff can observe and judge its usage, and at the same time, it can be easily replaced by the staff.

[0017] Optionally, the filter element is rotatably connected to the partition plate, and the filter element further includes an impeller; The impeller is located at the end of the core away from the partition, and the rotation axis of the filter element coincides with its own axis and the axis of the impeller.

[0018] By adopting the above technical solution, during the use of the filter, the liquid flowing in the filter chamber can drive the filter element to rotate by applying force to the impeller, which increases the difficulty for solid particles to get stuck in the first or second filter hole, and makes it easier for solid particles trapped in the first or second filter hole to leave. When cleaning the filter element, the cleaning water flowing in the filter chamber can also drive the filter element to rotate, so that the filter element has a certain self-cleaning effect.

[0019] Optionally, the first filter pore has its two side walls narrowed towards the first cavity along the rotation direction of the filter element, and the second filter pore has its two side walls narrowed towards the second cavity along the rotation direction of the filter element.

[0020] By adopting the above technical solution, solid particles trapped by the first or second filter holes can be easily removed by the rotation of the filter element and the flow of cleaning water, thereby effectively improving the effect and efficiency of filter element sludge removal and cleaning.

[0021] Optionally, the blades of the impeller are tilted.

[0022] By adopting the above technical solution, when the shell rotates to a horizontal state, the cleaning water can effectively drive the filter element to rotate by applying force to the impeller during the process of flowing through the shell, thereby facilitating the cleaning water to thoroughly clean the filter element and effectively improving the effect and efficiency of slag removal and cleaning of the filter element.

[0023] Optionally, the second housing is provided with a guide plate and a shielding cover at the position of the filter chamber near the water inlet pipe; The guide plate extends in a vortex shape, with its vortex axis coinciding with the axis of the housing, and a guide channel is formed on its inner side; one end of the guide channel is connected to the water inlet pipe, and it is used to guide the liquid to flow along the vortex trajectory. The shield is disposed on the side of the guide plate opposite to the water inlet pipe, and forms a shield in the area above the guide channel near the water inlet pipe.

[0024] By adopting the above technical solution, during the use of the filter, the flow of liquid in the filter chamber near the impeller can be effectively guided, so that the liquid flow can effectively drive the filter element to rotate, thereby effectively reducing the probability of the first or second filter pore being blocked by solid particles.

[0025] Optionally, the shield is rotatably connected to the guide plate, its rotation axis coincides with the axis of the housing, and its center of gravity is offset relative to its rotation axis. The outer surface of the guide plate is in contact with the side surface of the shielding cover near the filter element. Both are curved surfaces and together form a guide surface for guiding the liquid flowing toward it to reverse its direction and continue to flow.

[0026] By adopting the above technical solution, when the shell rotates to a horizontal state, cleaning water is poured into the interior of the shell through the water outlet pipe and discharged from the water inlet pipe. During this process, the cleaning water can change its flow direction after contacting the guide surface and continue to contact the filter element, thus achieving the effect of cleaning the filter element by removing slag. At the same time, a complex liquid flow can be formed near the impeller to drive the filter element to rotate, thereby further improving the effect and efficiency of cleaning the filter element by removing slag.

[0027] In summary, this application includes at least one of the following beneficial effects: 1. It allows staff to easily adjust the rotation position of the housing according to their needs, thereby cleaning the filter element by removing slag; 2. It allows staff to easily adjust the rotation position of the housing according to their needs, thereby enabling them to disassemble and replace the filter element. 3. It can reduce the probability of solid particles being trapped on the surface of the filter element during the use of the filter, thereby reducing the need for slag removal, cleaning, or disassembly and replacement of the filter element. 4. It can effectively improve the efficiency and effectiveness of the staff in cleaning the filter element, and at the same time, it can effectively ensure the reliability and stability of the staff in cleaning the filter element.

[0030] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail. Example 1

[0031] Reference Figure 1 and Figure 2 This application discloses a flip-type filter, which includes a housing 1, a plurality of filter elements 2 that perform filtration, and a base 3 for mounting the housing 1.

[0032] The shell 1 is cylindrical in shape and includes a first outer shell 11, a second outer shell 12, and a partition 13. The first outer shell 11 and the second outer shell 12 are respectively installed on both sides of the partition 13 and are detachably connected to the partition 13. After the first outer shell 11 and the second outer shell 12 are installed and connected to the partition 13, the first outer shell 11 and the partition 13 will enclose an outlet chamber 112 for the filtered solution to enter. The first outer shell 11 extends outward along its own axis in a direction away from the partition 13 for the solution to leave the outlet chamber 112. The second outer shell 12 and the partition 13 will enclose a filter chamber 122 for the solution before filtration to enter and be filtered. The second outer shell 12 extends outward along its own axis in a direction away from the partition 13 for the solution to enter the filter chamber 122. In this embodiment, it is preferred that the first outer shell 11 and the second outer shell 12 are detachably connected to the partition plate 13 by multiple bolts and nuts; and it is preferred that the volume of the filter chamber 122 is much larger than the volume of the liquid outlet chamber 112.

[0033] Reference Figure 2 and Figure 3 Multiple filter elements 2 can be detachably installed on the partition plate 13. All filter elements 2 are located inside the filter chamber 122, and the multiple filter elements 2 are evenly distributed on the partition plate 13. In this embodiment, the filter elements 2 are preferably fixedly connected to the partition plate 13 by threaded engagement.

[0034] Reference Figure 3 and Figure 4 The filter element 2 includes a core 21 and multiple filter elements 22.

[0035] Reference Figure 2 and Figure 4 The core 21 has a cylindrical structure. After the filter element 2 is installed on the partition 13, the axis of the core 21 is parallel to the axis of the shell 1. The end of the core 21 away from the partition 13 is close to the water inlet pipe 121 and has a certain distance between it and the inner wall of the filter chamber 122. The interior of the core 21 has a first cavity 211 that is cylindrical in shape. The axis of the first cavity 211 coincides with the axis of the core 21, and the end of the first cavity 211 near the partition 13 is connected to the liquid outlet chamber 112. Multiple first filter holes 212 for filtering solid particles are evenly opened on the outer side of the core 21, and the first cavity 211 is connected to the space outside the core 21 through the multiple first filter holes 212. In this embodiment, preferably, the two side walls of the first filter holes 212 along the circumference of the core 21 are narrowed towards the first cavity 211, so that solid particles stuck in the first filter holes 212 from the outside of the core 21 can be removed during slag removal and cleaning.

[0036] The filter element 22 has an overall arc-shaped plate structure. Multiple protrusions extend radially outward from the outer side of the core 21 for detachable installation of the filter element 22, and these protrusions are evenly spaced along the axial direction of the core 21. After multiple filter elements 22 are installed on the core 21, a ring-shaped second cavity 23 is formed between the filter element 22 and the core 21. The second cavity 23 communicates with the first cavity 211 through multiple first filter holes 212. Multiple second filter holes 221 are uniformly perforated on the filter element 22, and the second cavity 23 communicates with the filter chamber 122 through these second filter holes 221. In this embodiment, preferably, the diameter of the second filter holes 221 is larger than the diameter of the first filter holes 212; and preferably, the two side walls of the second filter holes 221 along the circumference of the core 21 are constricted towards the second cavity 23, facilitating the removal of solid particles trapped in the second filter holes 221 on the outside of the filter element 22 during slag removal and cleaning.

[0037] Reference Figure 1 and Figure 2 The base 3 includes a frame 31 for rotatably mounting the housing 1. The rotation axis of the housing 1 is horizontal and perpendicular to its axis, facilitating the adjustment of the position of the housing 1 by the operator as needed. In this embodiment, the housing 1 is preferably rotatably connected to the base 3 at a position on the second outer shell 12 near the partition 13.

[0038] When the housing 1 is rotated relative to the base 3 to a position where its axis is vertical and the outlet pipe 111 is above the inlet pipe 121, the filter is in use, and the outlet pipe 111 and the inlet pipe 121 are respectively connected to the corresponding pipes 4. In this embodiment, it is preferable that the ends of the outlet pipe 111 and the inlet pipe 121 have flange structures to facilitate their connection with the pipes 4.

[0039] When the housing 1 is rotated relative to the base 3 to a horizontal position, the filter is in a state where it is convenient for workers to disassemble the housing 1 and remove multiple filter elements 2. This also allows workers to easily introduce cleaning water into the housing 1 through the outlet pipe 111 or inlet pipe 121, helping solid particles trapped by the first filter hole 212 or the second filter hole 221 to leave the interior of the housing 1 with the cleaning water, thus achieving the removal of sludge from the filter elements 2. In other embodiments, workers can also perform sludge removal, cleaning, or replacement of the filter elements 2 when the housing 1 is rotated relative to the base 3 to an inclined position.

[0040] When the housing 1 is rotated relative to the base 3 to a position where its axis is vertical and the outlet pipe 111 is below the inlet pipe 121, the filter is in a state that facilitates the removal and cleaning of the multiple filter elements 2. This allows workers to easily introduce cleaning water into the housing 1 through the inlet pipe 121, helping to discharge solid particles trapped in the first cavity 211 and the second cavity 23 along with the cleaning water through the outlet pipe 111, thus further cleaning the filter elements 2. In other embodiments, workers can also perform further cleaning of the filter elements 2 when the housing 1 is rotated relative to the base 3 to a position where its axis is tilted and the outlet pipe 111 is below the inlet pipe 121.

[0041] The implementation principle of a flip-type filter in this application embodiment is as follows: During normal operation of the filter, the solution first enters the filter chamber 122 through the inlet pipe 121, then passes through multiple filter elements 2 and enters the outlet chamber 112, and is finally discharged through the outlet pipe 111. During the process of the solution passing through the filter elements 2, some of the solid particles mixed in the solution will be intercepted by multiple first filter holes 212 and multiple second filter holes 221, while the other part of the solid particles will be trapped in the first cavity 211 and the second cavity 23. After the filter has been working normally for a period of time, when the filter element 2 becomes clogged with solid particles and its filtration effect on the solution decreases to a certain extent, the staff can choose to clean or disassemble the filter element 2 according to its usage. When cleaning the filter element 2, first disconnect the inlet pipe 121 and outlet pipe 111 from the pipe 4. Then, control the housing 1 to rotate relative to the frame 31 in one direction until the axis is horizontal. After that, use the outlet pipe 111 as the inlet to introduce cleaning water into the housing 1, and then discharge the cleaning water through the inlet pipe 121. During this process, the cleaning water will clean the multiple filter elements 2 near the bottom of the filter chamber 122, removing the solid particles trapped by the filter elements 2. Then, control the housing 1 to rotate relative to the frame 31 in another direction until the axis is horizontal. Then, water is introduced into the housing 1 through the outlet pipe 111 and discharged through the inlet pipe 121. During this process, the water will clean the multiple filter elements 2 near the bottom of the filter chamber 122, removing the solid particles trapped by the filter elements 2. Finally, the housing 1 is rotated relative to the frame 31 to a position where the axis is vertical and the filter elements 2 are inverted. Then, water is introduced into the housing 1 through the inlet pipe 121 and discharged through the outlet pipe 111. The water will remove the solid particles trapped inside the filter elements 2. When disassembling and replacing filter element 2, first disconnect the inlet pipe 121 and outlet pipe 111 from the pipe 4, then control the housing 1 to rotate relative to the frame 31 in one direction until the axis is horizontal. After that, the first housing 11 and the partition 13 can be disassembled in sequence, and multiple filter elements 2 can be removed and replaced on the partition 13. Finally, the filter can be restored according to the previous steps. Example 2

[0042] Reference Figure 5 and Figure 6 Based on the technical solution disclosed in Example 1, this embodiment has been further optimized and refined. It can effectively delay the situation where the filter element 2 is not able to filter the solution due to solid particles clogging during the normal operation of the filter, and can also effectively improve the efficiency and effect of the staff in cleaning the filter element 2 by removing slag.

[0043] The improvement to the base 3 is that the base 3 also includes a first drive member 32, a base 33, and a second drive member 34.

[0044] The first driving component 32 is fixedly mounted on the frame 31 and is used to drive the housing 1 to rotate relative to the frame 31. The base 33 is fixedly mounted on the ground, and the frame 31 is movably mounted above the base 33, with its direction of movement being horizontal and perpendicular to the rotation axis of the housing 1. The second driving component 34 is fixedly mounted on the base 33 and is used to drive the frame 31 to move relative to the base 33. In this embodiment, the first driving component 32 is preferably a servo motor, and the second driving component 34 is preferably a lead screw transmission structure controlled by a servo motor. Since servo motors and lead screw transmission structures controlled by servo motors are common existing technologies, they will not be described in detail here, and they are only briefly shown in the accompanying drawings.

[0045] At this time, when the staff adjusts the position of the housing 1 according to the needs, they only need to control the first drive component 32 to drive the housing 1 to rotate relative to the frame 31 to the required position. This frees up the staff's hands, effectively reduces the difficulty and fatigue of operation, and reduces manpower input. After the housing 1 is disconnected from the pipe 4, the staff can control the second drive component 34 to drive the frame 31 to move, so that the housing 1 has more room for rotation adjustment. At the same time, it is convenient for the staff to perform slag removal, cleaning, or disassembly and installation of the filter element 2 inside the housing 1 from a position as far away from the pipe 4 as possible, reducing the probability of the filter or the staff being injured by bumping into the surrounding structure during the operation.

[0046] Reference Figure 6 and Figure 7 The improvement to housing 1 is that, in order to facilitate the connection and separation of the filter with the external pipe 4 through the inlet pipe 121 and the outlet pipe 111, housing 1 also includes two connecting pipes 14 and two sealing rings 15.

[0047] Two connecting pipes 14 are movably installed on the outside of the inlet pipe 121 and the outlet pipe 111, respectively. The direction of movement of the connecting pipes 14 is parallel to the axial direction of the housing 1, and the movement of the connecting pipes 14 relative to the housing 1 is restricted. Two sealing rings 15 are detachably installed on the outside of the inlet pipe 121 and the outlet pipe 111, respectively, and are located near the ends of the inlet pipe 121 and the outlet pipe 111. The outer sides of the ends of the inlet pipe 121 and the outlet pipe 111 each have protrusions extending outward for positioning the installation position of the sealing rings 15. After the sealing rings 15 are fitted onto the inlet pipe 121 or the outlet pipe 111, they will fit tightly against the corresponding protrusions. The inner side of the connecting pipe 14 has an abutment portion 141 for pressing the sealing rings 15, and the connecting pipe 14 is movably engaged with the inlet pipe 121 or the outlet pipe 111 through the abutment portion 141. In this embodiment, the sealing ring 15 is preferably made of elastic rubber, and the surfaces of the inlet pipe 121 and the outlet pipe 111 are both provided with grooves to facilitate the installation and positioning of the sealing ring 15; and preferably, the end of the connecting pipe 14 away from the housing 1 has a flange structure to facilitate its connection with the pipe 4.

[0048] When the connecting pipe 14 moves to its limit position in the direction closer to the housing 1, the adjacent sealing ring 15 is located on the side of the connecting pipe 14 away from the housing 1, and the exposed sealing ring 15 is easy for the staff to observe its usage so that it can be replaced in time; when the connecting pipe 14 moves to its limit position in the direction away from the housing 1, the adjacent sealing ring 15 will be located between the protrusion and the abutment part 141; then, during the process of the housing 1 being connected to the pipe 4 through the connecting pipe 14, the connecting pipe 14 will move further away from the housing 1, so that the sealing ring 15 is squeezed, thereby improving the sealing performance of the sealing ring 15 between the connecting pipe 14 and the inlet pipe 121 or the outlet pipe 111.

[0049] Reference Figure 6 and Figure 8 The improvement to housing 1 is that the second housing 12 has a guide plate 16 and a shield 17 installed inside it near the water inlet pipe 121 to guide the direction of liquid flow.

[0050] The guide plate 16 extends on the second housing 12 in a vortex trajectory, and the axis of its vortex trajectory coincides with the axis of the second housing 12; the guide plate 16 forms a guide channel 161 for guiding the liquid to flow along its vortex trajectory, one end of the guide channel 161 is directly connected to the water inlet pipe 121, the other end is connected to the outer space in the radial direction of the guide plate 16, and it is directly connected to the filter chamber 122 in the direction away from the water inlet pipe 121 along the axial direction.

[0051] The shielding cover 17 has a semi-circular plate-like structure. It is rotatably mounted on the guide plate 16 and located on the side of the guide plate 16 away from the water inlet pipe 121. Its rotation axis coincides with both the axis of its own semicircle and the axis of the water inlet pipe 121. During the rotation of the shielding cover 17 relative to the guide plate 16, the shielding cover 17 remains on the side of the guide channel 161 away from the water inlet pipe 121 in the area directly communicating with the water inlet pipe 121, forming a shield and being able to shield the guide channel 161 on the side away from the water inlet pipe 121. At least half of the area is shielded; the center of gravity of the shielding cover 17 is eccentrically set relative to its axis of rotation, and its center of gravity is centered along its semi-circular trajectory; after the liquid flowing along the guide channel 161 leaves the shielding area of ​​the shielding cover 17, it will continue to flow in the filter chamber 122 in a vortex trajectory for a certain period of time, and when the housing 1 is in a position where the axis is tilted or horizontal, the shielding cover 17 will rotate relative to the guide plate 16 under its own gravity, so that its position in the filter chamber 122 is generally lower.

[0052] The shield 17 has an arc surface on the side away from the guide plate 16, and the outermost surface of the guide plate 16 is also an arc surface. The outermost surface of the guide plate 16 can be connected to the surface of the shield 17 on the side away from the guide plate 16, and the two arc surfaces that are connected will jointly form a guide surface 18 for guiding the liquid flowing towards itself to change its flow direction.

[0053] The improvement to filter element 2 is that the core 21 is rotatably connected to the partition 13, and its rotation axis coincides with its own axis. During the rotation of the core 21 relative to the partition 13, the first cavity 211 remains in communication with the liquid outlet cavity 112. Filter element 2 also includes an impeller 24 for driving the core 21 to rotate relative to the partition 13. The impeller 24 is fixedly installed at the end of the core 21 away from the partition 13 and located near the guide plate 16. The axis of the impeller 24 coincides with the axis of the core 21, and the blades of the impeller 24 are inclined relative to the axis of the core 21. In this embodiment, preferably, the core 21 achieves a detachable and rotatable connection with the partition 13 through a connecting piece rotatably connected to itself and threadedly engaged with the partition 13. Since structures with the above functions are common existing technologies, they will not be described in detail here, and are only briefly shown in the accompanying drawings.

[0054] The implementation principle of a flip-type filter in this application embodiment is as follows: During normal operation of the filter, the solution first enters the guide channel 161 through the inlet pipe 121, then enters the filter chamber 122 through the guide channel 161, and then passes through multiple filter elements 2 before entering the outlet chamber 112, and finally is discharged through the outlet pipe 111. Furthermore, the solution that has just left the guide channel 161 will come into contact with multiple impellers 24, driving multiple filter elements 2 to rotate relative to the baffle 13. This can reduce the probability of solid particles being trapped by the filter elements 2, and also facilitate the exit of solid particles trapped by the filter elements 2 from the first filter hole 212 or the second filter hole 221. Similarly, during the process of the solution passing through the filter elements 2, some solid particles mixed in with the solution will be trapped by multiple first filter holes 212 and multiple second filter holes 221, while other solid particles will be trapped in the first cavity 211 and the second cavity 23. After the filter has been working normally for a period of time, when the filter element 2 becomes clogged with solid particles and its filtration effect on the solution decreases to a certain extent, the staff can choose to clean or disassemble the filter element 2 according to its usage. When cleaning the filter element 2, first disconnect the two connecting pipes 14 from the pipe 4. Then, control the second driving component 34 to move the frame 31 away from the base 33 away from the pipe 4.

During this process, the cover 17 will rotate relative to the guide plate 16 under its own weight until it is in a lower position in the filter chamber 122. At this time, the operator can control the connecting pipe 14 to move towards the housing 1 to its limit position, observe the condition of the sealing ring 15, and decide whether to replace it based on the actual situation. After that, the water outlet pipe... 111 is the water inlet end that introduces cleaning water into the interior of the housing 1, and the cleaning water is discharged through the water inlet pipe 121. During this process, the cleaning water will clean the multiple filter elements 2 near the bottom in the filter chamber 122, removing the solid particles trapped by the filter elements 2. At the same time, the cleaning water will drive the multiple filter elements 2 near the bottom in the filter chamber 122 to rotate, and after contacting the guide surface 18, it will change its flow direction and re-contact the multiple filter elements 2 near the bottom in the filter chamber 122, effectively improving the cleaning effect and efficiency of the filter elements 2. Then, the first driving member 32 is controlled to drive the housing 1 to rotate relative to the frame 31 in another direction to a horizontal position. During this process, the shielding Under its own weight, the cover 17 will rotate relative to the guide plate 16 to a position slightly lower than the overall position in the filter chamber 122. At this time, the operator can control the connecting pipe 14 to move towards the housing 1 to its limit position, observe the condition of the sealing ring 15, and decide whether to replace it based on the actual situation. Afterward, cleaning water is introduced into the housing 1 through the outlet pipe 111, and then discharged through the inlet pipe 121. During this process, the cleaning water will clean the multiple filter elements 2 near the bottom of the filter chamber 122, removing the solid particles trapped by the filter elements 2. At the same time, the cleaning water will drive the filter elements 2 near the bottom of the filter chamber 122 to remove sludge. Multiple filter elements 2 rotate, and after contacting the guide surface 18, their flow direction changes, and they re-contact the multiple filter elements 2 near the bottom of the filter chamber 122, further effectively improving the slag removal and cleaning effect and efficiency of the filter elements 2; finally, the first driving component 32 is controlled to drive the housing 1 to rotate relative to the frame 31 to a position where the axis is vertical and the filter elements 2 are inverted, and then cleaning water is introduced into the housing 1 through the water inlet pipe 121 and discharged through the water outlet pipe 111, so that the solid particles trapped inside the filter elements 2 are removed by the cleaning water; at the same time, the cleaning water can drive multiple filter elements 2 to rotate, further improving the efficiency and effect of removing solid particles by the cleaning water; When disassembling and replacing filter element 2, first disconnect the inlet pipe 121 and outlet pipe 111 from the pipe 4, then control the housing 1 to rotate relative to the frame 31 in one direction until the axis is horizontal. After that, the first housing 11 and the partition 13 can be disassembled in sequence, and multiple filter elements 2 can be removed and replaced on the partition 13. Finally, the filter can be restored according to the previous steps.
