Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pharmaceutical wastewater treatment, and particularly relates to a pharmaceutical wastewater integrated treatment equipment. BACKGROUND

[0002] The pharmaceutical industry is a core industry related to people's health, but a large amount of special industrial wastewater, i.e., pharmaceutical wastewater, is generated in the production process. The pharmaceutical wastewater is collectively referred to as the industrial wastewater generated in the whole process of the synthesis of raw pharmaceuticals, the production of preparations, the extraction of traditional Chinese medicine, and the fermentation of organisms. Due to the characteristics of complex composition, strong toxicity, and difficult degradation, this type of wastewater has become a “hard bone” in the field of industrial wastewater treatment. The extraction wastewater of Chinese patent medicine mainly contains natural organic matter, and the main components are sugars, organic acids, glycosides, anthraquinones, lignins, alkaloids, tannins, proteins, starches, and their hydrolysis products. If this wastewater is directly discharged, it will affect the health of the surrounding residents, and the treated water quality needs to meet the environmental protection discharge requirements. Therefore, the pharmaceutical factory will establish a pharmaceutical wastewater treatment equipment near the factory to treat the wastewater to meet the discharge standards.

[0003] A sewage MBR treatment device to prevent blockage is disclosed in a Chinese patent document with the authorization announcement number CN118754300B. The sewage MBR treatment device to prevent blockage includes support feet, a transmission assembly, a cleaning assembly, and a self-cleaning mechanism. The support feet are fixedly connected to a body at the top. The body is provided with an MBR membrane assembly. A fixed plate is fixedly connected to the front surface of the body. Built-in filter plates are fixedly connected to the left and right sides of the front surface of the body. The transmission assembly includes a transmission cylinder, which is fixedly connected to the front surface of the fixed plate.

[0004] However, the structure design of the above-mentioned related technology can clean the built-in filter plate, but when the MBR membrane inside is severely polluted, it still needs to be taken out of the treatment tank for offline cleaning. However, since the MBR membrane is located inside the body, when the MBR membrane is disassembled, the entire device needs to be taken out of the tank or the sewage needs to be discharged into the tank to disassemble the MBR membrane. Either way will cause the sewage treatment to be interrupted, thereby affecting the efficiency of sewage treatment.

[0005] Therefore, a pharmaceutical wastewater integrated treatment equipment is proposed to solve the problems mentioned above. SUMMARY

[0006] The present application provides a pharmaceutical wastewater integrated treatment equipment, which aims to solve the problem that offline cleaning of the MBR membrane will cause the sewage treatment to be interrupted in the related technology.

[0007] The integrated pharmaceutical wastewater treatment equipment of the present invention includes a shell, a support mechanism is provided inside the shell, the support mechanism has upper and lower support seats, two sets of positioning mechanisms are provided on the support mechanism, and multiple filtration mechanisms are provided inside the positioning mechanism.

[0008] The filtration mechanism includes a filter assembly disposed in the positioning mechanism, multiple arc-shaped filter plates mounted on the filter assembly, and a pressure plate slidably connected to the multiple filter plates; the filter assembly includes a mounting base, a filter tube mounted on the mounting base, a connecting base mounted on the filter tube, and a protrusion mounted on the connecting base, the protrusion being conical.

[0009] The positioning mechanism includes a support component inserted into the upper support base and a support component inserted into the lower support base. The support component has a first insertion hole for the mounting base to be inserted, and the support component has a second insertion hole for the connecting base to be inserted. Limiting components for restricting the connecting base are provided on both sides of the second insertion hole. A set of locking components and a set of positioning components are provided on the outside of the first insertion hole. Each set of positioning components can form a conical space. The positioning components are inserted into the locking components to limit the opening range of the conical space formed by the positioning components.

[0010] When a filter unit needs to be disassembled individually, the mounting base is lifted using hoisting equipment. The mounting base then moves the connecting seat upwards via the filter plate, allowing the filter unit to be disassembled separately. When the filter unit needs to be installed, the protrusion is first passed through insertion hole one. The conical space formed by multiple positioning components allows the protrusion to move vertically downwards. As the protrusion passes through the positioning components, the connecting seat enters insertion hole one, and simultaneously, the pressure plate falls onto the locking component. The locking component unlocks the positioning components, causing the connecting seat to spread out the multiple positioning components. After the connecting seat passes through the multiple positioning components, these components adhere to the outer side of the filter plate, keeping the filter plate vertical during downward movement until the connecting seat is inserted into insertion hole two. At this point, the limiting component limits the connecting seat, completing the installation of the filter unit.

[0011] Preferably, a plurality of filter plates are arranged in a ring array between the mounting base and the connecting base, and the bottom of the filter plates is located at the top edge of the connecting base. The connecting base has slots on both sides, and the inner bottom wall of the slots has an inclined surface. The top and bottom ends of the connecting base and the top of the protrusion all have arc-shaped surfaces.

[0012] When the connector is inserted into socket two, the limiting component can be inserted into the slot to lock the connector. When the connector moves upward, the limiting component can be pushed out by the inclined surface on the bottom wall of the slot, so that the connector moves out of socket two.

[0013] Preferably, the pressure plate has multiple sliding grooves for the filter plate to slide, and a locking block is installed on the inner wall of the sliding groove. The inner side of the filter plate has a limiting groove for the locking block to slide. The bottom end of the pressure plate has multiple spiral grooves connected end to end, and the depth of the first end of the spiral groove is less than the depth of the last end.

[0014] Preferably, the support assembly includes a lifting plate and two insert blocks installed on both sides of the lifting plate. The upper support base has a slot for inserting the insert blocks. There are multiple insert holes, which are evenly distributed on the lifting plate. The interior of the lifting plate near the outer side of the insert holes has multiple receiving slots for accommodating positioning components. The interior of the lifting plate near the upper part of the receiving slots has an installation slot for installing locking components.

[0015] Preferably, each group of locking components has multiple locking components, which are arranged in a circular array on the outside of the first socket. Each locking component includes a vertically movable frame and a first and a second tooth mounted on the movable frame. The movable frame is U-shaped and located in a receiving groove. The second tooth can engage with the positioning component to prevent it from rotating.

[0016] When the second tooth engages with the positioning component, it can prevent the positioning component from rotating, so as to avoid the positioning component from opening directly when the protrusion enters multiple positioning components. When the movable frame moves down in the receiving groove, it can drive the second tooth to move out of the positioning component, so that multiple positioning components can rotate, so that the positioning component opens and allows the connecting seat to pass through.

[0017] Preferably, the locking assembly further includes a top rod, a sliding plate, and a ball bearing. The top rod is mounted on the movable frame, and the ball bearing is disposed at the top of the top rod. The ball bearing can cooperate with the spiral groove on the pressure plate. The sliding plate is mounted on the top rod and is elastically slidably connected in the mounting groove. When the filter mechanism is installed in place, its own weight is applied to the ball bearing through the pressure plate, driving the pressure plate to rotate along the spiral groove, thereby driving the entire filter mechanism to rotate until the limiting assembly aligns with the slot and engages.

[0018] When the pressure plate falls onto the push rod, the weight of the pressure plate can squeeze the ball and move the push rod downward. At the same time, the push rod drives the second tooth to move out of the positioning assembly through the movable frame, thereby enabling the positioning assembly to rotate so that the subsequent positioning assembly can open.

[0019] Preferably, each group of positioning components comprises multiple components, which are arranged in a circular array on the outer side of the first insertion hole. Each positioning component includes a rotating shaft, a toothed gear, two rotating brackets, and a fan-shaped positioning plate. The rotating shaft is rotatably connected to the receiving groove, the toothed gear is mounted on the rotating shaft, the two rotating brackets are respectively mounted on the outer sides of the two ends of the rotating shaft, and both rotating brackets are mounted on the positioning plate. The conical space enclosed by each group of positioning components is composed of the positioning plates from the multiple positioning components.

[0020] Preferably, the support assembly includes a support plate and two insert blocks 2 respectively installed on both sides of the support plate. The lower support base has a slot for inserting the insert blocks 2, and the slot on the upper support base allows the insert blocks 2 to pass through. A vertical plate is installed between the lifting plate and the support plate. Multiple insertion holes 2 are opened on the support plate. Two connecting slots are symmetrically opened on the outside of the insertion holes 2 inside the support plate. The limiting assembly is disposed in the connecting slots.

[0021] Preferably, the limiting component includes an elastic sheet, a slider, and a limiting post. The elastic sheet is installed on the inner wall of the communicating groove, the slider is installed on the elastic sheet, one end of the limiting post is installed on the slider, and the other end of the limiting post passes through the communicating groove and extends into the second insertion hole. The other end of the limiting post is arc-shaped.

[0022] When the protrusion enters the second socket, it can push the limiting post into the connecting groove. When the slot corresponds to the limiting post, the limiting post can be inserted into the slot, thereby limiting the connection seat.

[0023] Preferably, a support column connects the upper support base and the lower support base, the upper support base is provided with a water outlet assembly, the water outlet assembly has multiple connecting pipes, and the mounting base is provided with a collection pipe that communicates with the connecting pipes.

[0024] The beneficial effects of the present invention, achieved by adopting the above technical solution, are as follows: When a filter mechanism needs to be disassembled separately, the mounting base is lifted by a hoisting device. At this time, the mounting base moves the connecting base upward through the filter plate, thereby enabling the filter mechanism to be disassembled separately. When the filter mechanism needs to be installed, the protrusion is first passed through the first insertion hole. At this time, the protrusion can move vertically downward through the conical space formed by multiple positioning components. During the process of the protrusion passing through multiple positioning components, the connecting base enters the first insertion hole, and at the same time, the pressure plate falls onto the locking component. At this time, the locking component unlocks the positioning component, allowing the connecting base to open the multiple positioning components. After the connecting base passes through the multiple positioning components, the multiple positioning components adhere to the outside of the filter plate, so that the filter plate remains vertical during the downward movement until the connecting base is inserted into the second insertion hole. At this time, the connecting base is limited by the limiting component to complete the installation of the filter mechanism. Moreover, the wastewater treatment does not need to be stopped during the installation or disassembly of the filter mechanism, so as to avoid the interruption of wastewater treatment and thus improve the efficiency of wastewater treatment.

[0040] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0041] like Figures 1 to 10 As shown, the integrated pharmaceutical wastewater treatment equipment of the present invention includes a shell 10, a support mechanism 20, a filtration mechanism 30, and a positioning mechanism 40. An inlet pipe and an outlet pipe are respectively provided on both sides of the shell 10. Inside the shell 10, from the inlet pipe to the outlet pipe, an anoxic tank, an aerobic tank, a sedimentation tank, an air flotation tank, and an MBR reaction tank are arranged sequentially. The support mechanism 20 is located in the MBR reaction tank of the shell 10. There are two sets of both the filtration mechanism 30 and the positioning mechanism 40, with the two sets of positioning mechanisms 40 symmetrically distributed on the support mechanism 20. The two sets of filtration mechanisms 30 are respectively located inside the two sets of positioning mechanisms 40.

[0042] When it is necessary to disassemble one of the filter mechanisms 30, pull the filter mechanism 30 upwards. This will separate the filter mechanism 30 from the positioning mechanism 40, allowing the filter mechanism 30 to be disassembled and cleaned individually. When it is necessary to disassemble a group of filter mechanisms 30, lift the group of positioning mechanisms 40 using hoisting equipment. This will separate the positioning mechanisms 40 from the support mechanism 20, allowing the group of filter mechanisms 30 to be moved out of the housing 10.

[0043] like Figures 1 to 2 As shown, the support mechanism 20 includes an upper support base, a lower support base, and a water outlet assembly. The upper support base includes two upper support frames 21, and the lower support base includes two lower support frames 22. Multiple connecting frames 23 are installed between the two upper support frames 21 and the two lower support frames 22. Two support columns 24 are installed between the upper and lower support bases, and the support columns 24 are located between the connecting frames 23 on the upper support frames 21 and the connecting frames 23 on the lower support frames 22. The water outlet assembly is located on top of the connecting frames 23 on the upper support frames 21 to discharge the water treated by the filtration mechanism 30.

[0044] Continue to refer to Figures 1 to 2 As shown, the water outlet assembly includes a support plate 25, a fixed pipe 26, a connecting pipe 27, and an outlet pipe 28. There are two support plates 25 and two outlet pipes 28. The support plate 25 is mounted on top of the connecting frame 23, the fixed pipe 26 is mounted between the two support plates 25, and the two outlet pipes 28 are respectively mounted at both ends of the fixed pipe 26. The outlet ends of both outlet pipes 28 are connected to external pipes. There are two sets of connecting pipes 27. One end of each set of connecting pipes 27 is mounted on the fixed pipe 26, and the other ends of each set of connecting pipes 27 are connected to two sets of filter mechanisms 30.

[0045] After being treated by the filter mechanism 30, the water enters the fixed pipe 26 through the connecting pipe 27, and the water in the fixed pipe 26 is discharged through the outlet pipe 28.

[0046] like Figures 1 to 4As shown, the filtration mechanism 30 includes a filter assembly 31, filter plates 32, and an adjustment assembly 34. The filter assembly 31 includes a mounting base 311, a collection pipe 312, filter pipes 313, a connecting base 314, and a protrusion 315. One end of the collection pipe 312 is mounted on the top of the mounting base 311, and the other end is disposed on the connecting pipe 27. Hanging rings are mounted on both sides of the mounting base 311. Multiple filter pipes 313 are installed between the mounting base 311 and the connecting base 314. Multiple filter plates 32 are arc-shaped and arranged in a circular array between the mounting base 311 and the connecting base 314, with the bottom of each filter plate 32 located at the top edge of the connecting base 314. Multiple filter pipes 313 are located inside the filter plates 32, and limiting grooves 33 are formed on the inner side of the filter plates 32. The adjustment assembly 34 is slidably connected to the limiting grooves 33 on the multiple filter plates 32. The protrusion 315 is installed at the bottom of the connector 314. The protrusion 315 is conical in shape. The top of both sides of the connector 314 are provided with slots 316. The inner bottom wall of the slots 316 has a slope. The top and bottom of the connector 314 and the top of the protrusion 315 all have arc-shaped surfaces.

[0047] After being treated by the filter pipe 313, the wastewater enters the mounting base 311. The wastewater entering the mounting base 311 flows into the connecting pipe 27 along the collection pipe 312.

[0048] When the filter mechanism 30 needs to be disassembled, the mounting base 311 is lifted by a hoisting device, allowing for direct disassembly of the filter mechanism 30. When the filter mechanism 30 needs to be installed, it is placed into the positioning mechanism 40 by the hoisting device. During the lowering of the filter mechanism 30, the positioning mechanism 40 keeps it vertical. When the filter mechanism 30 is lowered to the designated position, the positioning mechanism 40 engages with the slot 316 of the connecting base 314, completing the installation of the filter mechanism 30. Furthermore, wastewater treatment can be continued during the disassembly and installation processes.

[0049] like Figures 3 to 5 As shown, the adjusting assembly 34 includes a pressure plate 341 and spiral grooves 344. The top of the pressure plate 341 has multiple arc-shaped sliding grooves 342, in which the filter plate 32 is slidably connected. A locking block 343 is installed on the inner wall of the sliding groove 342, and the locking block 343 is slidably connected in the limiting groove 33 of the filter plate 32. There are multiple spiral grooves 344 arranged in a circular array at the bottom of the pressure plate 341. The beginning and end of the spiral grooves 344 are connected, and the depth of the beginning of the spiral groove 344 is less than the depth of the end.

[0050] like Figure 2 and Figures 6 to 7As shown, the positioning mechanism 40 includes a support component 41, a locking component 43, a positioning component 44, a vertical plate 45, and a supporting component 46. The support component 41 is inserted into the upper support frame 21, and the supporting component 46 is inserted into the lower support frame 22, with the supporting component 46 able to pass through the upper support frame 21. There are two vertical plates 45, both installed between the support component 41 and the supporting component 46. The support component 41 has multiple insertion holes 42 for the mounting base 311 to be inserted. There are multiple sets of locking components 43 and positioning components 44, with multiple sets of locking components 43 located on the outside of the multiple insertion holes 42, and multiple sets of positioning components 44 located on the outside of the multiple insertion holes 42. There are multiple sets of each locking component 43 and each set of positioning components 44. The multiple locking components 43 are inserted into the multiple positioning components 44, and the multiple locking components 43 and multiple positioning components 44 are arranged in a circular array on the outside of the insertion holes 42.

[0051] When the filter tube 313 needs cleaning, the mounting base 311 is lifted using hoisting equipment, allowing the filter tube 313 to be removed. When the filter tube 313 needs to be installed, the protrusion 315 is first passed through the insertion hole 42. At this time, the protrusion 315 enters between multiple positioning components 44 and moves vertically downward under the constraint of the positioning components 44. As the protrusion 315 continues to move downward, the connecting seat 314 spreads open the multiple positioning components 44. After the connecting seat 314 passes the positioning components 44, the multiple positioning components 44 fit against the outside of the filter plate 32, so that the filter plate 32 remains vertical during the downward movement, until the connecting seat 314 is inserted into the support component 46.

[0052] like Figures 6 to 9 As shown, the support assembly 41 includes a lifting plate 411 and insert blocks 412. There are two insert blocks 412, each installed on one side of the lifting plate 411. The top of the upper support frame 21 has slots on both sides for inserting the insert blocks 412. Multiple insertion holes 42 are evenly distributed on the lifting plate 411. The interior of the lifting plate 411, near the outer side of the insertion holes 42, has multiple receiving slots 413 for accommodating positioning components 44. Above the receiving slots 413, the interior of the lifting plate 411 has a mounting slot 414 for mounting locking components 43.

[0053] Continue to refer to Figures 6 to 9As shown, the locking assembly 43 includes a movable frame 431, a first insert 432, a second insert 433, a push rod 434, a sliding plate 435, an elastic element 436, and a ball bearing 437. The movable frame 431 is located inside the receiving groove 413, and the movable frame 431 is U-shaped. The first insert 432 and the second insert 433 are respectively installed on the inner top wall and the inner bottom wall of the movable frame 431, and both the first insert 432 and the second insert 433 can be inserted into the positioning assembly 44. In the initial state, the second insert 433 is inserted into the positioning assembly 44 to prevent the positioning assembly 44 from rotating. The push rod 434 is installed on the top of the movable frame 431, and the top end of the push rod 434 penetrates through the top of the lifting plate 411 and extends to the outside of the lifting plate 411. The ball bearing 437 is rotatably connected to the top end of the push rod 434. The slide plate 435 is installed on the outside of the top rod 434 and is slidably connected to the inner wall of the mounting groove 414. The elastic element 436 is a cylindrical spring and is installed between the slide plate 435 and the inner wall of the mounting groove 414.

[0054] When the protrusion 315 passes through the positioning assembly 44, the connecting seat 314 enters the insertion hole 42. At this time, the pressure plate 341 falls onto the push rod 434, and the ball 437 on the push rod 434 enters the spiral groove 344 of the pressure plate 341. Then, by the weight of the pressure plate 341, the ball 437 can be squeezed, causing the ball 437 to drive the push rod 434 to move down. The push rod 434 drives the first tooth 432 and the second tooth 433 to move down through the movable frame 431, so that the second tooth 433 moves out of the positioning assembly 44, thereby releasing the limitation on the positioning assembly 44. At this time, the connecting seat 314 can open up multiple positioning assemblies 44.

[0055] As the protrusion 315 continues to move downward, the locking block 343 on the pressure plate 341 slides in the limiting groove 33 of the filter plate 32 to further ensure the vertical state of the filter plate 32. When the connecting seat 314 is inserted into the supporting assembly 46, the mounting seat 311 presses on the pressure plate 341 to further apply gravity to the ball bearing 437. At this time, the ball bearing 437 rolls in the spiral groove 344 to make the pressure plate 341 rotate. During the rotation of the pressure plate 341, the connecting seat 314 can be driven to rotate through the filter plate 32, preventing the limiting assembly 47 from failing to align with the locking groove 316 on the connecting seat 314, thus ensuring that the limiting assembly 47 can be accurately inserted into the locking groove 316, achieving an automatic alignment effect, thereby reducing the adjustment time of the operator and improving the installation efficiency of the filter tube 313.

[0056] Continue to refer to Figures 6 to 9As shown, the positioning assembly 44 includes a rotating shaft 441, a toothed gear 442, a rotating frame 443, and a positioning plate 444. The rotating shaft 441 is rotatably connected to the inner wall of the receiving groove 413. The toothed gear 442 is installed on the outer side of the rotating shaft 441, and the movable frame 431 is located on the outer side of the toothed gear 442. In the initial state, the second tooth 433 is inserted into the bottom of the toothed gear 442, and the first tooth 432 is located above the toothed gear 442. There are two rotating frames 443, which are respectively installed on the outer sides of both ends of the rotating shaft 441. A torque spring (not shown in the figure) is provided between the rotating frame 443 and the inner wall of the receiving groove 413. The positioning plate 444 is fan-shaped, and the positioning plates 444 in the multiple positioning assemblies 44 can form a conical space at the bottom end of the insertion hole 42. Both rotating frames 443 are installed on the top of the positioning plate 444.

[0057] When the protrusion 315 passes through the insertion hole 42 and enters between the multiple positioning plates 444, the restriction of the multiple positioning plates 444 allows the protrusion 315 to be centered and remain vertical as it passes through the multiple positioning plates 444. As the protrusion 315 continues to move downward, the pressure plate 341 presses on the ball 437, causing the ball 437 to drive the push rod 434 downward. The push rod 434, through the movable frame 431, drives the first shaping tooth 432 and the second shaping tooth 433 downward, so that the second shaping tooth 433 moves out of the toothed gear 442, and at the same time, the first shaping tooth 432 contacts the outer side of the toothed gear 442, so that the subsequent positioning plate 444 can open. During the process of the connecting seat 314 passing through the positioning plate 444, the connecting seat 314 expands the positioning plate 444. At this time, the positioning plate 444 drives the toothed gear 442 to rotate through the rotating frame 443, while the torque spring stores force. When the teeth on the missing tooth gear 442 come into contact with the first tooth 432, the missing tooth gear 442 stops rotating due to the restriction of the first tooth 432, so that the connecting seat 314 just passes through the multiple positioning plates 444.

[0058] When the connecting seat 314 passes through multiple positioning plates 444, the torque spring resets and drives the positioning plates 444 to fit onto the filter plate 32 through the toothed gear 442, so that the filter plate 32 remains vertical during the downward movement.

[0059] When the mounting base 311 presses against the pressure plate 341, the pressure transmitted from the pressure plate 341 to the ball bearings 437 increases, causing the ball bearings 437 to roll in the spiral groove 344, thereby causing the pressure plate 341 to rotate. During the rotation of the pressure plate 341, it can drive the connecting base 314 to rotate through the filter plate 32, so that the limiting component 47 corresponds to the slot 316 on the connecting base 314, facilitating the insertion of the limiting component 47 into the slot 316.

[0060] like Figure 3 , Figure 6 , Figure 7 and Figure 10As shown, the support assembly 46 includes a support plate 461 and two insert blocks 462. There are two insert blocks 462, installed on opposite sides of the support plate 461. The support plate 461 is located inside the lower support frame 22, and the upright plate 45 is installed between the lifting plate 411 and the support plate 461. The top of the lower support frame 22 has slots on both sides for inserting the insert blocks 462, and the slots on the upper support frame 21 allow the insert blocks 462 to pass through. The top of the support plate 461 has multiple insertion holes 463 for inserting the connecting seats 314. Two symmetrical connecting slots 464 are located inside the support plate 461 near the outer side of the insertion holes 463. A limiting assembly 47 capable of inserting a slot 316 is installed inside the connecting slots 464.

[0061] When the protrusion 315 enters the second socket 463, the protrusion 315 pushes the limiting component 47 into the connecting groove 464. When the connector 314 is inserted into the second socket 463, the limiting component 47 extends and inserts into the slot 316 of the connector 314 to limit the connector 314, at which point the installation of the filter tube 313 is completed.

[0062] like Figure 6 and Figure 10 As shown, the limiting assembly 47 includes an elastic sheet 471, a slider 472, and a limiting post 473. One end of the elastic sheet 471 is mounted on one side of the inner wall of the connecting groove 464, and the other end of the elastic sheet 471 is mounted on the slider 472, with the slider 472 slidably connected to the connecting groove 464. One end of the limiting post 473 is mounted on one side of the slider 472, and the other end of the limiting post 473 passes through the connecting groove 464 and extends into the second insertion hole 463; the other end of the limiting post 473 is arc-shaped.

[0063] When the protrusion 315 is inserted into the second socket 463, it first pushes the limiting post 473 into the connecting groove 464 and compresses the elastic piece 471. When the slot 316 corresponds to the limiting post 473, the force of the elastic piece 471 resetting can drive the limiting post 473 into the slot 316, thereby limiting the connection seat 314 and preventing the connection seat 314 from shaking.

[0064] Working principle: When it is necessary to disassemble one of the filter mechanisms 30, the mounting base 311 is lifted by a hoisting device. At this time, the mounting base 311 drives the connecting base 314 to move upward through the filter plate 32. During the upward movement of the connecting base 314, the limiting post 473 can be pushed out of the slot 316 by the inclined surface on the bottom wall of the slot 316. As the mounting base 311 continues to move upward, the connecting base 314 pushes open the multiple positioning plates 444, thereby allowing one of the filter mechanisms 30 to be disassembled individually.

[0065] When installing one of the filter mechanisms 30, the protrusion 315 is first passed through the insertion hole 42. At this time, the protrusion 315 can move vertically downward under the constraint of multiple positioning plates 444. As the protrusion 315 continues to move downward, the connecting seat 314 enters the insertion hole 42, and at the same time, the pressure plate 341 falls onto the push rod 434, and the ball bearings 437 on the push rod 434 enter the spiral groove 344 of the pressure plate 341. During the continued downward movement of the protrusion 315, the connecting seat 314 spreads open the multiple positioning plates 444. After the connecting seat 314 passes the positioning plates 444, the multiple positioning plates 444 fit against the outside of the filter plate 32, so that the filter plate 32 remains vertical during the downward movement. When the protrusion 315 is inserted into the insertion hole 463, the limiting post 473 is first pushed into the connecting groove 464 and the elastic sheet 471 is compressed. When the slot 316 corresponds to the limiting post 473, the force of the elastic sheet 471 resetting can drive the limiting post 473 to be inserted into the slot 316, thereby limiting the connection seat 314, and at this time the installation of the filter tube 313 is completed.

[0066] When the pressure plate 341 falls onto the push rod 434, its own weight compresses the ball bearing 437, causing it to move the push rod 434 downwards. The push rod 434, through the movable frame 431, moves the first and second shaping teeth 432 and 433 downwards, causing the second shaping tooth 433 to move out of the missing tooth gear 442. Simultaneously, the first shaping tooth 432 contacts the outer side of the missing tooth gear 442, releasing the restriction on the missing tooth gear 442 and allowing the subsequent positioning plate 444 to open. During the process of the connecting seat 314 passing through the positioning plate 444, the connecting seat 314 expands the positioning plate 444. At this time, the positioning plate 444 drives the missing tooth gear 442 to rotate through the rotating frame 443, while the torque spring stores force. When the teeth on the missing tooth gear 442 contact the first shaping tooth 432, the missing tooth gear 442 stops rotating due to the restriction of the first shaping tooth 432, allowing the connecting seat 314 to pass through multiple positioning plates 444.

[0067] During the insertion of the connecting seat 314 into the second insertion hole 463, the mounting seat 311 presses against the pressure plate 341 to further apply pressure to the ball bearing 437. At this time, the ball bearing 437 can roll in the spiral groove 344, causing the pressure plate 341 to rotate. During the rotation of the pressure plate 341, it can drive the connecting seat 314 to rotate through the filter plate 32, so as to ensure that the limiting post 473 can be accurately inserted into the slot 316, achieving an automatic alignment effect, thereby reducing the adjustment time of the operator and improving the installation efficiency of the filter tube 313.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
