Description

Technical Field

[0001] The present invention belongs to the technical field of filter assembly, and particularly relates to a carbon fiber sheet stacked filter assembly device and an assembly method. Background Art

[0002] Activated carbon fiber filter is an efficient filtering medium with the following characteristics: 1) Strong adsorption capacity: The adsorption rate of activated carbon fiber for organic gases and malodorous substances is dozens of times higher than that of granular activated carbon, especially suitable for low-concentration substances; 2) Deep filtration: Some models of filters combine the dual functions of activated carbon filtration and adsorption, and can effectively block pollution particles; 3) Wide application: Suitable for high-demand deodorization and decolorization filtration, widely used in fields such as air purification and water treatment. Activated carbon fiber filters are widely used due to their superior performance and are suitable for various industrial and household applications.

[0003] The structures of activated carbon fiber filters are diverse. There are filters with carbon fiber filter plates arranged as filter elements in the outer shell (such as those disclosed in CN202322364194.0), filters with a multi-layer sheet of activated carbon fiber sheet and water-permeable base material sheet wound tightly to form a cylindrical filter element with a roll-like structure (such as those disclosed in CN202180008826.0), and filters with an activated carbon fiber layer and an ion exchange layer alternately stacked along the side wall of the shell in the outer shell (such as those disclosed in KR1020100004702).

[0004] For a filter element formed by alternately stacking activated carbon fiber sheets (hereinafter referred to as carbon fiber sheets) and other filter layers (such as non-woven fabrics, ion exchange layers, etc.), the existing method is for workers to alternately arrange the two filter layers in the outer shell. For small filters, workers can directly place the filter layers (including activated carbon fiber sheets and other filter layers) layer by layer in the outer shell, or workers can divide the filter element into several stacked segments and place them in the outer shell in multiple times. For large filters, such as filters with a height of two or three meters, the outer shell is relatively deep and much taller than workers. With limited arm lengths of workers, it is difficult to place the filter element segments in the relatively deep outer shell. When using the method of sliding the filter element segments from the top to the bottom of the outer shell, the activated carbon dust generated by the collision of the filter element segments placed at high altitude is not only harmful to human health but also pollutes the environment. In addition, since the carbon fiber sheets are relatively brittle, there are cases where the carbon fiber sheets are damaged and broken during the transfer and placement in the outer shell, affecting the quality of the filter. Therefore, it is necessary to design an assembly device for carbon fiber sheet stacked filters.

[0005] After retrieval, no technical solution similar to the present invention has been publicly disclosed. Summary of the Invention

[0006] To solve the technical problems existing in the prior art, the first aspect of the present invention is to provide a carbon fiber sheet stacked filter assembly device. In the second aspect, based on the same inventive concept, the present invention also provides an assembly method based on the foregoing carbon fiber sheet stacked filter assembly device.

[0007] In an embodiment of the present invention, a carbon fiber sheet stacked filter assembly device, the filter includes a housing and a filter element disposed in the housing, the filter element is formed by two filter layers stacked alternately, and one of the filter layers is a carbon fiber sheet; the assembly device includes a stacking table, a worker lifting table, a clamping mechanism, a bottom supporting mechanism, and a handling driving device; the worker located on the worker lifting table can stack the filter layers onto the stacking table, and by lifting the worker lifting table, the worker thereon can be lifted along with the stacking height of the filter element; the clamping mechanism can open and close to clamp or loosen the housing, the handling driving device drives the clamping mechanism to move in space, and the clamping mechanism can sleave the housing it clamps outside the filter element on the stacking table; the handling driving device drives the bottom supporting mechanism to move in space, and the bottom supporting mechanism can be inserted into the bottom of the housing with the filter element on the stacking table; the bottom of the housing with the filter element is supported by the bottom supporting mechanism, and at the same time, the housing with the filter element is held tightly by the clamping mechanism, so as to lift the housing with the filter element and enable the housing with the filter element to move and rotate vertically.

[0008] The carbon fiber sheet stacked filter assembly method according to an embodiment of the present invention is implemented based on the foregoing carbon fiber sheet stacked filter assembly device, and includes the following steps: 1) Stacking the filter element: The worker located on the worker lifting table stacks a plurality of filter layers onto the stacking table, and the two filter layers are stacked alternately to form a filter element; 2) Sleaving the housing: The handling driving device drives the clamping mechanism to move in space, and the clamping mechanism clamps the housing and sleaves the housing outside the filter element on the stacking table; 3) Compacting the filter element: The handling driving device drives the compacting mechanism to move in space, and the compacting mechanism extends into the housing on the stacking table from the top, and the compacting mechanism presses down the filter element to compact the filter element; 4) Supplementing the filter layer: The worker located on the worker lifting table adds filter layers into the housing from the opening at the top of the housing until the housing is filled; 5) Fixing and installing one end cover: The worker installs an end cover at the opening at the top of the housing and fixes the end cover to the housing to block the opening at the top of the housing; 6) Fixing and installing the other end cover: The handling driving device drives the clamping mechanism and the bottom supporting mechanism to move in space, the bottom supporting mechanism is inserted from the bottom of the housing, the clamping mechanism holds tightly the housing with the filter element on the stacking table, the compacting mechanism is located at the top of the housing, the clamping mechanism lifts the housing with the filter element, and the handling driving device drives the clamping mechanism to move in space and rotate the housing, so that the end of the housing without the fixed and installed end cover is tilted upward, the bottom supporting mechanism is removed, and the worker fixes the end cover to the housing at the end of the housing without the fixed and installed end cover to block the opening at the other end of the housing; 7) Completing the assembly of the filter.

[0009] Compared with the prior art, the beneficial effects of the preferred technical solution of the present invention include:

[0010] 1. By providing a stacking table and a worker lifting platform, the worker is located on the worker lifting platform to stack the filter layer onto the stacking table, and the worker lifting platform rises and falls with the stacking height, thereby completing the stacking of the filter elements of higher filters; by providing a clamping mechanism and a handling driving device, the clamping mechanism clamps the outer shell and slews the outer shell over the stacked filter elements. Compared with stacking the filter elements by dropping them from the top of the outer shell, the present invention can avoid the activated carbon dust generated by the collision of carbon fiber sheets, which is more environmentally friendly; when lifting the outer shell containing the filter element and turning the outer shell to fix the end cover, the bottom supporting mechanism supports the bottom of the outer shell, avoiding the outer shell slipping off the clamping mechanism and the filter element slipping out of the outer shell, which is safe and reliable.

[0011] 2. By providing a stacking centering device to center the filter layer stacked on the stacking table, the centering degree (i.e., coaxiality) of the stacked filter elements is ensured; and the limiting mechanism of the stacking centering device can be lifted and lowered, leaving enough operating space for the clamping mechanism and not interfering with the clamping mechanism to pick up and place the outer shell on the stacking table.

[0012] 3. By providing a compaction mechanism to compact the filter element after slewing the outer shell, the density of the filter element is increased. On the one hand, it can avoid the filter element being too loose and affecting the filtering effect. On the other hand, it can also effectively control the shortening rate of the filter element length during the use of the filter, extending the service life of the filter element; and during the process of turning the outer shell to fix the end cover at the other end, the compaction mechanism can also support the end of the outer shell where the end cover has been fixedly installed, preventing the outer shell from slipping and improving the stability.

Detailed Embodiments

[0015] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0016] Embodiment 1

[0017] This embodiment provides a carbon fiber sheet stacked filter assembly device. Among them, the filter includes a housing 91 (the housing 91 can be made of a glass fiber cylinder or other materials) and a filter element 92 provided in the housing 91. The filter element 92 is formed by alternately stacking two types of filter layers. One type of filter layer is a carbon fiber sheet, and the other type of filter layer can be made of non-woven fabric, ion exchange layer, or water-permeable substrate sheet, etc. according to actual situations.

[0018] As Figure 1 shown, in a preferred embodiment, the filter assembly device of the present invention includes a stacking table 10, a worker lifting table 20, a clamping mechanism 30, a bottom supporting mechanism 40, and a handling driving device 50.

[0019] A worker located on the worker lifting table 20 can alternately stack two types of filter layers (which can be placed on a liftable storage table beside the worker lifting table 20) onto the stacking table 10, and the worker lifting table 20 is lifted so that the worker on it can rise and fall with the stacking height of the filter element 92. The worker lifting table 20 can be an elevating chair. Usually, the worker sits on the worker lifting table 20 in a sitting position, and the worker can also stand on the worker lifting table 20 according to needs.

[0020] The clamping mechanism 30 can open and close to clamp or release the housing 91. Specifically, the clamping mechanism 30 can adopt electric grippers, such as the grippers disclosed in CN202010507350.2, CN202111653684.1, and CN202222400391.9. The handling driving device 50 drives the clamping mechanism 30 to move in space, and the clamping mechanism 30 can sleave the clamped housing 91 outside the filter element 92 on the stacking table 10.

[0021] The bottom supporting mechanism 40 can adopt a forklift claw, which has the same structure and function as the forklift claw. The handling driving device 50 drives the bottom supporting mechanism 40 to move in space, and the bottom supporting mechanism 40 can insert into the bottom of the housing 91 containing the filter element 92 on the stacking table 10. By using the bottom supporting mechanism 40 to support the bottom of the housing 91 containing the filter element 92, and at the same time, the clamping mechanism 30 tightly holds the housing 91 containing the filter element 92 to lift the housing 91 containing the filter element 92 and enable the housing 91 containing the filter element 92 to move and rotate vertically. After vertical rotation, the lower end of the housing 91 can be tilted upward to facilitate the installation of an end cap on the housing 91.

[0022] When using this assembly equipment to assemble the filter, the worker on the worker lifting platform 20 stacks the filter layers onto the stacking platform 10, and the two filter layers are stacked alternately to form a filter element 92; then the handling driving device 50 drives the clamping mechanism 30 to move in space, and the clamping mechanism 30 clamps the outer shell 91 and slews the outer shell 91 outside the filter element 92 on the stacking platform 10; next, the worker installs an end cap on the top of the outer shell 91 and fixes the end cap to the outer shell 91. The handling driving device 50 drives the clamping mechanism 30 and the bottom supporting mechanism 40 to move in space. The bottom supporting mechanism 40 inserts from the bottom of the outer shell 91 and supports the filter element 92 inside the outer shell 91, and the clamping mechanism 30 tightly holds the outer shell 91 with the filter element 92 on the stacking platform 10. The clamping mechanism 30 picks up the outer shell 91 with the filter element 92, and the handling driving device 50 drives the clamping mechanism 30 to move in space and rotate the outer shell 91, so that the end of the outer shell 91 without the fixedly installed end cap is tilted upward (a slight tilt is sufficient) to turn around the outer shell 91. During this process, the bottom supporting mechanism 40 holds the bottom of the outer shell 91 to prevent the outer shell 91 from slipping off the clamping mechanism 30 during the handling of the outer shell 91 with the filter element 92. Then the bottom supporting mechanism 40 is removed, and the worker fixedly connects the end cap to the end of the outer shell 91 without the fixedly installed end cap to complete the assembly of the filter.

[0023] It should be noted that in order to prevent the filter element 92 from slipping out of the outer shell 91 during the handling of the outer shell 91 with the filter element 92, the end cap of the filter can be placed on the stacking platform 10 first, and the filter element 92 is stacked on the end cap on the stacking platform 10; of course, a supporting plate can also be arranged on the stacking platform 10, and the size of the supporting plate is larger than the sizes of the filter element 92 and the outer shell 91, and the filter element 92 is stacked on the supporting plate on the stacking platform 10. The bottom supporting mechanism 40 inserts into the bottom of the end cap / supporting plate, and the bottom supporting mechanism 40 holds the bottom of the outer shell 91 through the end cap / supporting plate. Preferably, the supporting plate has a limiting retaining edge arranged around the outer shell 91, which can prevent the supporting plate from slipping off the outer shell 91 and falling when the outer shell 91 is tilted and the bottom supporting mechanism 40 is removed.

[0024] In an embodiment of the present invention, the handling driving device 50 includes a mounting column 51 for mounting the clamping mechanism 30 and the bottom supporting mechanism 40, a lifting column 52 for driving the mounting column 51 to lift (such as the electric lifting column 52 disclosed in CN202211257042.4 and CN201910789192.1), a lateral driving mechanism 53 for driving the mounting column 51 to move laterally to approach or move away from the stacking platform 10, a horizontal rotation driving mechanism 54 for driving the mounting column 51 connected to the lifting column 52 to rotate horizontally, and a vertical rotation driving mechanism 55 for driving the mounting column 51 connected to the horizontal rotation driving mechanism 54 to rotate vertically.

[0025] Among them, the lateral driving mechanism 53 includes a track 531 fixed to the ground and pointing to the stacking table 10, a rack 532 fixed to the ground and arranged parallel to the track 531, a gear 533 meshing with the rack 532 and capable of horizontally rotating the lift column 52, and a gear driving motor 534 for driving the gear 533 to rotate. The number of tracks 531 is two. The rack 532 is located between the two tracks 531. The lift column 52 is installed on the two tracks 531 and can slide on the tracks 531. The gear driving motor 534 drives the gear 533 to rotate, causing the gear 533 to roll on the rack 532, so that the lift column 52 moves on the track 531. All of these are prior arts and will not be described in detail here. The horizontal rotation driving mechanism 54 is installed on the top of the lift column 52, for example, a rotating motor with an output shaft extending vertically upward is used. The vertical rotation driving mechanism 55 is installed on the top of the horizontal rotation driving mechanism 54, for example, a rotating motor with an output shaft extending to one side of the mounting column 51 is used.

[0026] The present invention realizes the lifting of the mounting column 51 in the vertical direction through the lift column 52, realizes the horizontal rotation of the mounting column 51 through the horizontal rotation driving mechanism 54, and makes the mounting column move horizontally closer to or farther away from the stacking table 10 through the lateral driving mechanism 53, so as to realize the position movement of the mounting column 51 carrying the clamping mechanism 30 and the bottom supporting mechanism 40 in three-dimensional space; realizes the vertical rotation of the mounting column 51 carrying the clamping mechanism 30 and the bottom supporting mechanism 40 through the vertical rotation driving mechanism 55 to adjust the spatial angle of the outer shell 91 (for example, making the outer shell 91 lie horizontally, vertically or obliquely). Preferably, a counterweight 56 is provided at one end of the mounting column 51 away from the vertical rotation driving mechanism 55.

[0027] It should be noted that the lateral driving mechanism 53 may not adopt the form of moving the lift column 52 on the track 531, but an electric cylinder or a pneumatic cylinder is installed on the vertical rotation driving mechanism 55 to directly drive the mounting column 51 to move horizontally. At this time, the lift column 52 is fixed to the ground.

[0028] Further, a bottom driving mechanism 41 for driving the bottom supporting mechanism 40 to rotate relative to the mounting post 51 so as to be aligned or staggered with the clamping mechanism 30 is mounted on the mounting post 51 (for example, a rotating motor with an output shaft extending along the length direction of the mounting post 51). Thus, when carrying the outer shell 91, the bottom supporting mechanism 40 and the clamping mechanism 30 can be staggered so that the bottom supporting mechanism 40 does not interfere with the outer shell 91, or the bottom supporting mechanism 40 and the clamping mechanism 30 can be aligned to facilitate the two to jointly lift the outer shell 91 containing the filter element 92. For example, when the clamping mechanism 30 slews the outer shell 91 it clamps over the filter element 92 on the stacking table 10, the bottom supporting mechanism 40 rotates relative to the mounting post 51 to be staggered with the clamping mechanism 30 and is located outside the outer shell 91, without affecting the clamping mechanism 30 slewing the outer shell 91 over the filter element 92 on the stacking table 10; for another example, when it is necessary to lift the outer shell 91 containing the filter element 92, the bottom supporting mechanism 40 and the clamping mechanism 30 are aligned, the bottom supporting mechanism 40 is inserted into the bottom of the outer shell 91, and the clamping mechanism 30 clamps the middle of the outer shell 91 to lift the outer shell 91 containing the filter element 92; for still another example, when the clamping mechanism 30 lifts the outer shell 91 containing the filter element 92 to make the outer shell 91 inclined for installing the end cover, the bottom supporting mechanism 40 can be rotated to be located outside the outer shell 91 to provide an installation space for installing the end cover of the outer shell 91.

[0029] In another preferred embodiment, the assembly equipment further includes a compaction mechanism 60 mounted on the mounting post 51. The compaction mechanism 60 is driven by the handling driving device 50 to move in space. The compaction mechanism 60 includes a pressing block 61 capable of extending into the outer shell 91 on the stacking table 10 from the top, and a compaction driving member 62 for driving the pressing block 61 to move vertically to compact the filter elements 92 stacked in the outer shell 91 (for example, a vertically arranged electric cylinder or air cylinder). The compaction driving member 62 is mounted on a connecting rod fixedly connected to the mounting post 51.

[0030] After the filter elements 92 on the stacking table 10 are stacked to a set height, the clamping mechanism 30 slews the outer shell 91 over the filter elements 92. The top of the filter element 92 is flush with or slightly lower than the upper end of the outer shell 91. The pressing block 61 is located above the top of the outer shell 91 and there is a certain distance between them. The compaction driving member 62 drives the pressing block 61 to move downward and applies a certain pressure (for example, a force of 350 kg) to compact the stacked filter elements 92. After compaction, the height of the filter elements 92 decreases, and then some filter layers are added from the top of the outer shell 91 until it is full.

[0031] In another preferred embodiment, the assembly device further includes a stacking and centering device 70, which includes a limiting mechanism 71 and a centering lifting drive mechanism 72 for driving the limiting mechanism 71 to lift and lower; when stacking the filter elements 92 on the stacking table 10, the worker places the filter layer in the limiting mechanism 71 for stacking. The limiting mechanism 71 guides and centers the filter layer therein, and the centering lifting drive mechanism 72 drives the limiting mechanism 71 to lift and lower along with the stacking height of the filter elements 92 to ensure the centering degree of the stacked filter elements 92.

[0032] Specifically, the limiting mechanism 71 includes two relatively arranged arc-shaped limiting blocks 711. The filter layer can be located between the two limiting blocks 711 and is limited by the two limiting blocks 711. The two limiting blocks 711 are installed on the cross frame 712. The centering lifting drive mechanism 72 drives the cross frame 712 to move vertically so that the two limiting blocks 711 lift and lower. The centering lifting mechanism is arranged outside the stacking table 10. The centering lifting drive mechanism 72 can adopt a sprocket and chain mechanism in the prior art, or a structure of a motor plus a lead screw and a lead screw sleeve to lift the cross frame 712.

[0033] Preferably, the distance between the two limiting blocks 711 is adjustable, or the opening and closing angle between the two limiting blocks 711 is adjustable to limit and center filter elements 92 with different diameters. Specifically, the limiting mechanism 71 can adopt the same jaw structure as the clamping mechanism 30, or manually adjust the distance and opening and closing angle between the two limiting blocks 711 through bolts.

[0034] In another preferred embodiment, the assembly device further includes a placing table 80, which includes a plurality of spaced support blocks 81. Each support block 81 is connected with a support lifting drive mechanism 82 (such as a lifting column or an electric cylinder) for driving it to lift and lower. The outer shell 91 can be placed on the plurality of support blocks 81 and supported by the plurality of support blocks 81. The clamping mechanism 30 can pick up and place the outer shell 91 from the gap between the support blocks 81.

[0035] Initially, the housing 91 is placed horizontally on the placement table 80, the bottom supporting mechanism 40 is staggered with the clamping mechanism 30, the mounting column 51 is rotated to a horizontal state by the vertical rotation driving mechanism 55, the mounting column 51 is rotated horizontally and toward the placement table 80 by the horizontal rotation driving mechanism 54, the mounting column 51 is lifted and lowered by the lifting column 52, the fully opened clamping mechanism 30 faces the outer side of the housing 91 and does not interfere with the housing 91 (the pressing block 61 and the bottom supporting mechanism 40 are respectively located on both sides of the housing 91), and the outer housing 91 is clamped by the closed clamping mechanism 30. The shell 91 is clamped, and the clamping mechanism 30 removes the shell 91 from the placement table 80 by lifting and rotating the mounting column 51 horizontally. The shell 91 is placed in a vertical state by rotating the mounting column 51 to a vertical state. The lifting column 52 is moved on the track 531 to bring the shell 91 close to the stacking table 10, and the mounting column 51 is rotated horizontally at the same time, so that the shell 91 is located directly above the filter element 92 on the stacking table 10 and is centered. The mounting column 51 is lowered to allow the shell 91 to be sleeved over the filter element 92 on the stacking table 10.

[0036] In another preferred embodiment, the assembly equipment further includes a lifting table (not shown in the figure) for storing the two filter layers. The height of the table can be raised and lowered by various lifting platforms in the prior art. The table is raised and lowered with the stacking height of the filter element 92 on the stacking table 10. The worker picks up the filter layer on the table and stacks it on the stacking table 10. Specifically, a table can be set on one side of the worker lifting platform 20 for storing the two filter layers, or a table can be set on both sides of the worker lifting platform 20 for storing the two filter layers respectively, according to actual needs. In actual use, the two filter layers can be packaged and placed on the lifting table, and the AGV forklift can be used to move the table.

[0037] Embodiment 2

[0038] This embodiment provides a method for assembling a carbon fiber sheet stacked filter, which is implemented based on the carbon fiber sheet stacked filter assembly device of the first embodiment, and includes the following steps:

[0039] 1) Stacking filter elements 92: A worker on the worker lifting platform 20 picks up the filter layer on the storage platform, stacks the filter layer in the limiting mechanism 71 placed on the stacking platform 10 for centering, and the filter layer is stacked on the stacking platform 10. The limiting mechanism 71 rises and falls with the stacking height. When the stacking reaches a set height (specifically, a ruler can be set on the housing 91 of the centering lifting drive mechanism 72 to measure the stacking height), the stacking is stopped, and the two filter layers are stacked alternately to form a filter element 92. After the filter element 92 is stacked, the limiting mechanism 71 is lowered to the lowest position, or the distance between the two limiting blocks 711 is increased to leave space for the subsequent sleeve of the housing 91.

[0040] 2) Sleeving the outer shell 91: The transport drive device 50 drives the clamping mechanism 30 to move in space, and the clamping mechanism 30 clamps the horizontal outer shell 91 on the placement table 80 (at this time, the bottom support mechanism 40 and the clamping mechanism 30 are offset). The transport drive device 50 drives the clamping mechanism 30 to move, so that the outer shell 91 moves in space and rotates the outer shell 91 from a horizontal state to a vertical state, and the outer shell 91 is sleeved on the outside of the filter element 92 on the stacking table 10.

[0041] 3) Compacting the filter element 92: The transport drive device 50 also drives the compacting mechanism 60 to move in space. Since the compacting mechanism 60 is also installed on the mounting column 51, it moves in space together with the clamping mechanism 30. The clamping mechanism 30 sets the outer shell 91 on the outside of the filter element 92 on the stacking platform 10. The compacting mechanism 60 is located above the outside of the outer shell 91 and there is a certain distance between the two. The pressing block 61 of the compacting mechanism 60 extends from the top into the outer shell 91 on the stacking platform 10. The compacting mechanism 60 presses the filter element 92 down through the pressing block 61 to compact the filter element 92. After compacting the filter element 92, the compacting drive 62 drives the pressing block 61 to move upward to the outside of the outer shell 91.

[0042] 4) Supplementing the filter layer: After the filter element 92 is compacted, the height of the filter element 92 is lowered, and the worker located on the worker lifting platform 20 adds the filter layer into the outer shell 91 through the opening at the top of the outer shell 91 until the outer shell 91 is filled.

[0043] 5) Fixing and installing one end cover: The worker on the worker lifting platform 20 installs the end cover at the top opening of the shell 91 and fixes the end cover to the shell 91 to block the top opening of the shell 91. After the end cover is installed on the top of the shell 91, the worker lifting platform 20 descends and the worker leaves the worker lifting platform 20.

[0044] 6) Fix and install the end cover on the other side: the transport drive device 50 drives the clamping mechanism 30 and the bottom supporting mechanism 40 to move in space, the bottom supporting mechanism 40 is inserted from the bottom of the shell 91, the clamping mechanism 30 holds the shell 91 with the filter element 92 on the stacking table 10, the compacting mechanism 60 is located on the top of the shell 91 and the pressing block 61 is in contact with the end cover, the clamping mechanism 30 picks up the shell 91 with the filter element 92, the bottom supporting mechanism 40 holds the bottom of the shell 91 with the filter element 92, the transport drive device 50 drives the installation column 51 to rotate, the installation column 51 makes the clamping mechanism 30 and the shell 91 rotate together, so that the end of the shell 91 where the end cover is not fixedly installed is tilted upward, and the end of the shell 91 where the end cover is fixedly installed is tilted downward and supported by the pressing block 61 of the compacting mechanism 60 to prevent the shell 91 from slipping. The lifting column 52 lowers the housing 91, and the workers on the ground fix the end cover of the housing 91 to the housing 91 where the end cover is not fixed to block the opening at the other end of the housing 91. The end covers at both ends of the housing 91 limit the two ends of the filter element 92.

[0045] 7) Complete the assembly of the filter. The assembled filter can be placed on the storage rack and transported away by an AGV forklift after being placed.

[0046] It should be noted that in the present invention, the lifting of the worker lift table 20, the limiting mechanism 71 and the storage table, as well as the operation of the clamping mechanism 30, the bottom support mechanism 40, the handling drive device 50 and the compaction mechanism 60 can be controlled by the worker through a remote control or an intelligent voice device, which are all prior arts and will not be described in detail herein.

[0047] In the present invention, the handling drive device drives the compaction mechanism to move in space. The method for the compaction mechanism to extend from the top into the outer shell on the stacking table and press down the filter element to compact the filter element is as follows:

[0048] F(d) = A(P0 - kln(d + d0))

[0049] Wherein, F(d) is the compaction force when the distance that the compaction mechanism extends from the top into the outer shell on the stacking table is d, A is the area of the compaction surface of the compaction mechanism, P0 is the initial pressure (which can be obtained through experiments when the filter element fills the outer shell), k is the speed coefficient of the pressure drop with the change of distance and can be obtained through experiments, and d0 is the reference depth (the value is greater than 1).

[0050] When the filter element does not fill the outer shell, when compacting the filter element, the above formula is used to dynamically adjust the force for compacting the filter element to compensate for the difference in the compaction state of the filter element at different depths, making the overall compactness more uniform; moreover, in the deep region (d is larger), the compaction force automatically decreases, reducing the risk of damaging the filter element material (such as cracking or deformation) due to excessive compaction force, and at the same time reducing the mechanical stress on the compaction mechanism or the outer shell. In addition, the parameters P0 and k can be calibrated through experiments to adapt to different filter element materials or outer shell sizes, improving the generalization ability of the solution.

[0051] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and purposes of the present invention. The scope of the present invention is defined by the claims and their equivalents.
