Description

Technical Field

[0001] The present invention belongs to the technical field of water treatment, and particularly relates to a wastewater treatment device for catalyst recovery. Background Art

[0002] During the regeneration and recovery of catalysts, various chemical substances are used for cleaning and treatment to remove impurities on the catalyst surface and restore its activity. These chemical substances need to be washed away after the reaction, resulting in wastewater containing catalyst residues, cleaning agent residues, and other impurities. Therefore, it is necessary to effectively treat the wastewater generated during the recovery process.

[0003] In a patent application document with the publication number CN118458998A, an industrial wastewater treatment device is disclosed, which includes a treatment tower. An opening and closing door is provided inside the treatment tower, and the opening and closing door divides the space inside the treatment tower into a reaction chamber located in the upper layer and a precipitation chamber located in the lower layer; a stirring mechanism is provided inside the treatment tower, and the stirring mechanism is located in the reaction chamber; a filter screen is connected to the inner wall of the treatment tower, and the filter screen is located in the precipitation chamber.

[0004] Existing wastewater treatment devices usually set partitions and filter screens inside the reaction tower to divide its interior into a reaction chamber and a precipitation chamber. After the wastewater completes the reaction in the reaction chamber, it flows into the precipitation chamber by opening the opening on the partition. At the same time, when the wastewater passes through the opening on the partition, the filter screen below the partition intercepts the larger solid materials in it for filtration.

[0005] Since the partition is located inside the reaction tower, in order to control the flow of wastewater and ensure that it can smoothly enter the precipitation chamber after the reaction, existing equipment usually designs through slots on the partition and installs baffles that can rotate along the axis of the reaction tower at the through slots to block the through slots. However, due to the limited size of the through slots, which usually only occupy a part of the partition area, the flow rate of wastewater through the partition is limited to a certain extent, which may lead to a reduction in the wastewater treatment efficiency. At the same time, this design may also cause some wastewater and solid impurities to remain on the partition. Summary of the Invention

[0006] The purpose of the present invention is to provide a wastewater treatment device for catalyst recovery, aiming to solve the problems in the prior art that the efficiency of wastewater entering the precipitation chamber from the reaction chamber in the reaction tower is low, and at the same time, some wastewater and solid impurities will remain in the reaction chamber.

[0007] To achieve the above purpose, the present invention provides the following technical solution: A wastewater treatment device for catalyst recovery, including a reaction tower and a transmission shaft located inside it and coaxial with it. A partition assembly is provided inside the reaction tower to divide the space inside the reaction tower into a reaction chamber located in the upper layer and a precipitation chamber located in the lower layer.

[0008] The partition assembly includes a mounting plate coaxially arranged with the transmission shaft, a plurality of rotating shafts uniformly distributed along the circumferential direction of the mounting plate, and a plurality of sector plates. The two ends of the rotating shaft are rotatably mounted on the outer wall of the mounting plate and the inner wall of the reaction tower respectively, and its axis extends radially along the mounting plate. The plurality of sector plates are sequentially arranged between two adjacent rotating shafts and together with the mounting plate and the rotating shaft form a complete circular plate. The outer wall of the rotating shaft is fixedly connected to the side wall of one of the sector plates. A mounting sleeve coaxial with the mounting plate is rotatably mounted on the bottom of the mounting plate. A plurality of support plates uniformly distributed along the circumferential direction thereof are fixedly mounted on the outer wall of the mounting sleeve. The plurality of support plates are respectively located at the bottom of the plurality of sector plates. A transmission mechanism for driving the rotation thereof is installed inside the mounting sleeve.

[0009] The beneficial effects of the present invention are as follows: the present scheme is designed to be composed of a plurality of concentric fan-shaped plates, a rotation axis is arranged between two adjacent fan-shaped plates, and each fan-shaped plate is connected to a fixed structure through a rotation axis. At the same time, a support plate swinging with the axis of the fan-shaped plate as the axis is arranged below each fan-shaped plate for support, so that the fan-shaped plate can be kept in a horizontal state, thereby making a plurality of fan-shaped plates be combined into a complete plate surface to separate the reaction chamber from the precipitation chamber. When the reaction chamber needs to be connected with the precipitation chamber, it is only necessary to rotate the support plate so that it rotates between the two fan-shaped plates. At this time, the support plate no longer supports the fan-shaped plate, and the fan-shaped plate can rotate downward 90 degrees with the rotation axis as the axis under its own gravity and the pressure of the wastewater in the reaction chamber, thereby opening the communication channel between the reaction chamber and the precipitation chamber to the greatest extent. Doing so not only speeds up the flow rate per unit time when the wastewater passes through the partition, but also avoids part of the wastewater and solid impurities from remaining on the partition assembly as much as possible.

[0010] The transmission mechanism includes an adjusting shaft and an adjusting sleeve fixedly installed at the bottom of the transmission shaft and coaxial therewith, a mounting hole coaxial therewith is opened on the top of the mounting plate, the bottom end of the adjusting shaft passes through the mounting hole, the adjusting sleeve is slidably sleeved on the bottom end of the outer wall of the adjusting shaft, the mounting sleeve is rotatably sleeved on the outer wall of the adjusting sleeve, a limiting sliding groove extending along its axial direction is opened on the inner side wall of the mounting hole, a limiting strip slidably sleeved in the limiting sliding groove is fixedly installed on the top of the outer wall of the adjusting sleeve, a transmission groove extending along its circumferential direction and inclined downward is opened on the outer wall of the adjusting sleeve, and a first transmission member located in the transmission groove and sliding along its extension direction is fixedly installed on the inner wall of the mounting sleeve.

[0011] The middle and bottom of the outer wall of the adjusting shaft are both provided with first sliding grooves extending along its circumferential direction. The first sliding grooves are annular grooves. The outer wall of the adjusting shaft is provided with second sliding grooves extending along its circumferential direction and inclined downward. The top and bottom of the second sliding grooves are respectively communicated with the two first sliding grooves. The bottom of the inner wall of the adjusting sleeve is fixedly installed with a second transmission member slidably sleeved in the first sliding groove. The inner wall of the adjusting shaft is provided with two receiving grooves. The two receiving grooves and the two first sliding grooves are respectively in the same first plane. Both of the two receiving grooves are provided with a limiting mechanism for making the second transmission member slide from the first sliding groove into the second sliding groove when the rotation direction of the adjusting shaft is changed.

[0012] There are two second sliding grooves and two second transmission members, and they are evenly distributed along the circumferential direction of the adjusting shaft. The two limiting mechanisms are symmetrically arranged with the midpoint between the two receiving grooves as the center. The limiting mechanism includes two sliders slidably arranged in the receiving groove along the left-right direction. An elastic member is fixedly installed between the mutually approaching ends of the two sliders. The other ends of the two sliders are both fixedly installed with limiting blocks. The ends of the two limiting blocks far from the sliders both slide through the adjusting shaft and extend into the first sliding groove. One side wall of the limiting block is an arc surface and the arc surface is in contact with the side wall of the second sliding groove. The other side wall of the limiting block is an inclined surface and the inclination direction of the inclined surface is the same as the extending direction of the first sliding groove.

[0013] The number of the limiting sliding grooves and the limiting strips is both two, and the two limiting sliding grooves and the two limiting strips are evenly distributed along the circumferential direction of the adjusting sleeve. The number of the transmission grooves and the first transmission members is both two, and the two transmission grooves and the two first transmission members are evenly distributed along the circumferential direction of the adjusting sleeve.

[0014] The effect is that by setting the transmission mechanism, the adjusting shaft and the limiting mechanism, we can control the lifting of the adjusting sleeve by controlling the forward and reverse rotation of the driving member, and then control the forward and reverse rotation of the installation sleeve. This series of actions can drive the support plate to rotate, so as to control the opening and closing of the sector plate, realizing the automatic opening and closing function of the partition component without adding an additional driving source.

[0015] A filtering component is further arranged inside the reaction tower. The filtering component includes a filter screen located above the partition component. The filter screen is fixedly installed on the inner wall of the reaction tower. A scraping mechanism is arranged above the filter screen for preventing the filter screen from being blocked.

[0016] The scraping mechanism includes a transmission sleeve fixedly sleeved on the top of the outer wall of the adjusting shaft. A plurality of scraping plates evenly distributed along its circumferential direction are fixedly installed on the outer wall of the transmission sleeve. The scraping plates extend along the radial direction of the transmission sleeve and the ends of the scraping plates far from the transmission sleeve are in sliding contact with the inner wall of the reaction tower. A tower door is arranged on the side wall of the reaction tower.

[0017] On both sides of the inner side wall of the transmission sleeve, there are clamping chutes extending along its radial direction. At the bottom of the clamping chutes, there are connecting chutes extending along the axial direction of the transmission sleeve. A clamping block is slidably installed in the clamping chutes, and a pressing block is slidably installed in the connecting chutes. The bottom of the pressing block slidably penetrates through the transmission sleeve. The top of the pressing block is an inclined surface, which gradually slopes upward from the side close to the adjusting shaft to the other side. One end of the clamping block away from the adjusting shaft is an inclined surface that cooperates with the inclined surface of the pressing block.

[0018] The effect is that by setting the scraping mechanism, the pressing block and the clamping block, when the partition assembly is opened, the scraping mechanism can scrape and wash the filter screen driven by the adjusting shaft, avoiding blockage due to solid impurities intercepted during the filtration of wastewater. At the same time, when the partition assembly is closed, the scraping mechanism no longer rotates with the adjusting shaft, thus reducing the load on the driving member and further reducing the energy consumption of the device.

[0019] Installation grooves are provided on the inner wall of the reaction tower and are evenly distributed along its circumferential direction. The support plate extends along the radial direction of the installation sleeve, and the end of the support plate away from the installation sleeve extends into the installation groove and is slidably connected thereto. On the top wall and the bottom wall of the installation groove, there are a plurality of card slots evenly distributed along the circumferential direction of the reaction tower. The number of card slots on the top wall and the bottom wall is the same, both matching the number of support plates, and they are symmetrically distributed up and down. The card slots are located below the rotating shaft. A clamping block is provided between the card slots on the top wall and the bottom wall of the installation groove, and the top and bottom of the clamping block are respectively slidably clamped in the card slots on the top wall and the bottom wall of the installation groove.

[0020] The effect is that by setting the installation groove, it can effectively support the end of the support plate away from the installation sleeve, thus enhancing the stability of the support plate. At the same time, by setting the card slots and the clamping block, it can accurately limit the stop position of the support plate during forward and reverse rotation, avoiding the installation sleeve and the support plate continuing to rotate due to inertia after the adjusting sleeve stops driving the installation sleeve to rotate, thereby affecting the normal opening and closing of the partition assembly.

[0021] A driving member is fixedly installed at the top of the reaction tower. The driving member is a motor. The top end of the transmission shaft penetrates through the top of the reaction tower and is in transmission connection with the output shaft of the motor. A plurality of stirring groups evenly distributed along its axial direction are fixedly installed on the outer wall of the transmission shaft. Each stirring group includes a plurality of stirring blades evenly distributed along the circumferential direction of the transmission shaft.

[0022] The effect is that by setting the stirring group, it can effectively stir the wastewater during the reaction precipitation process, thereby accelerating the reaction precipitation rate of the wastewater and further improving the efficiency of the device for treating waste chips.

[0023] Compared with the prior art, the beneficial effects of the present invention are: The partition is designed to be composed of a plurality of concentric fan-shaped plates, a rotation axis is set between two adjacent fan-shaped plates, and each fan-shaped plate is connected to a fixed structure through a rotation axis. At the same time, a support plate swinging with the axis of the fan-shaped plate as the axis is set under each fan-shaped plate for support, so that the fan-shaped plate can be kept in a horizontal state, and then a plurality of fan-shaped plates are combined into a complete plate surface to separate the reaction chamber from the sedimentation chamber. When the reaction chamber needs to be connected with the sedimentation chamber, it is only necessary to rotate the support plate to rotate it between the two fan-shaped plates. At this time, the support plate no longer supports the fan-shaped plate, and the fan-shaped plate can rotate downward 90 degrees with the rotation axis as the axis under its own gravity and the pressure of the wastewater in the reaction chamber, thereby opening the communication channel between the reaction chamber and the sedimentation chamber to the greatest extent. This not only speeds up the flow rate per unit time when the wastewater passes through the partition, but also avoids part of the wastewater and solid impurities from remaining on the partition assembly as much as possible.

[0029] Refer to Figure 1 and Figure 6 As shown, a transmission shaft 2 coaxial with it is rotatably installed inside the reaction tower 1. The top end of the transmission shaft 2 penetrates the top of the reaction tower 1 and is in transmission connection with the output shaft of the driving member 11 through a coupling. A plurality of stirring groups 22 are fixedly installed on the outer wall of the transmission shaft 2. These stirring groups 22 are evenly distributed along the axial direction of the transmission shaft 2. Each stirring group 22 includes a plurality of stirring blades. These stirring blades are evenly distributed along the circumferential direction of the transmission shaft 2. The bottom end of the transmission shaft 2 is fixedly installed with an adjusting shaft 21 coaxially arranged with it.

[0030] Refer to Figure 2 and Figure 3As shown, the partition assembly 3 includes a mounting disk 31, a rotating shaft 32, a sector plate 33, a mounting sleeve 34, and a support plate 35.

[0031] A mounting hole 311 coaxial with it is opened at the center of the top of the mounting disk 31. The mounting hole 311 is rotatably sleeved on the outer wall of the adjusting shaft 21, and the mounting disk 31 is coaxially arranged with the adjusting shaft 21. There are multiple rotating shafts 32 evenly distributed along the circumferential direction of the mounting disk 31. The rotating shafts 32 are located between the mounting disk 31 and the inner wall of the reaction tower 1, and their axes extend along the radial direction of the mounting disk 31. The two ends of the rotating shaft 32 are respectively rotatably mounted on the outer wall of the mounting disk 31 and the inner wall of the reaction tower 1. The number of sector plates 33 is the same as that of the rotating shafts 32. Multiple sector plates 33 are sequentially arranged between two adjacent rotating shafts 32, and together with the mounting disk 31 and the rotating shafts 32, they form a complete circular plate. The outer wall of each rotating shaft 32 is fixedly connected to the side wall of a sector plate 33.

[0032] Reference Figure 2 、 Figure 4 and Figure 5 As shown, the mounting sleeve 34 is located below the mounting disk 31, coaxially with it, and sleeved on the outer wall of the adjusting shaft 21. The number of support plates 35 is the same as that of the sector plates 33 and they are evenly distributed in the circumferential direction of the mounting sleeve 34. Multiple support plates 35 are respectively located at the bottoms of multiple sector plates 33. An installation groove 14 extending along the circumferential direction of the reaction tower 1 is opened on the inner wall of the reaction tower 1. The installation groove 14 is an annular groove. The support plate 35 extends along the radial direction of the mounting sleeve 34, and the end of the support plate 35 away from the mounting sleeve 34 extends into the installation groove 14 and is slidably connected to it. A plurality of clamping grooves 15 evenly distributed along the circumferential direction of the reaction tower 1 are opened on the top wall and the bottom wall of the installation groove 14. The number of clamping grooves 15 on the top wall and the bottom wall is the same, both matching the number of support plates 35, and they are symmetrically distributed up and down. The clamping grooves 15 are located below the rotating shaft 32. A clamping block 37 is provided between the clamping grooves 15 on the top wall and the bottom wall of the installation groove 14. The top and bottom of the clamping block 37 are respectively slidably clamped in the clamping grooves 15 on the top wall and the bottom wall of the installation groove 14. A transmission mechanism is installed inside the mounting sleeve 34, and this transmission mechanism is used to drive its rotation. By rotating the mounting sleeve 34, the position of the support plate 35 can be adjusted so that the support plate 35 no longer supports the sector plate 33. At this time, the sector plate 33 will rotate downward with the rotating shaft 32 as the axis, thereby connecting the reaction chamber and the precipitation chamber.

[0033] Reference Figure 6As shown, the transmission mechanism includes an adjustment sleeve 36, which is sleeved between the outer wall of the adjustment shaft 21 and the inner wall of the mounting sleeve 34. Driven by the adjustment shaft 21, the adjustment sleeve 36 slides up and down reciprocally along its axis. On the inner side wall of the mounting hole 311 of the mounting disc 31, a limiting chute 312 extending along its axis is provided. At the top of the outer wall of the adjustment sleeve 36, a limiting strip 361 slidably sleeved in the limiting chute 312 is fixedly installed. The number of the limiting chute 312 and the limiting strip 361 is two each, and these two limiting chutes 312 and two limiting strips 361 are evenly distributed along the circumferential direction of the adjustment sleeve 36. On the outer wall of the adjustment sleeve 36, a transmission groove 362 extending along its circumferential direction and inclined downward is also provided. On the inner wall of the mounting sleeve 34, a first transmission member 341 located in the transmission groove 362 and sliding along its extending direction is fixedly installed. The number of the transmission groove 362 and the first transmission member 341 is also two each, and these two transmission grooves 362 and two first transmission members 341 are also evenly distributed along the circumferential direction of the adjustment sleeve 36. In this embodiment, the first transmission member 341 is a roller; in other embodiments, the first transmission member 341 can also be a roller with an axis extending radially along the mounting sleeve 34.

[0034] Reference Figure 7 As shown, on the middle part and the bottom of the outer wall of the adjustment shaft 21, first chutes 211 extending along its circumferential direction are provided, and these first chutes 211 are annular grooves. In addition, on the outer wall of the adjustment shaft 21, a second chute 212 extending along its circumferential direction and inclined downward is also provided, and the top and the bottom of the second chute 212 are respectively communicated with the two first chutes 211. At the bottom of the inner wall of the adjustment sleeve 36, a second transmission member 363 slidably sleeved in the first chute 211 is fixedly installed, and the second transmission member 363 is a roller. In other embodiments, the second transmission member 363 can also be a roller with an axis extending radially along the adjustment sleeve 36.

[0035] Two receiving grooves 213 are provided in the inner wall of the adjustment shaft 21, and these two receiving grooves 213 are respectively in the same plane as the two first chutes 211. A limiting mechanism is provided in the receiving groove 213, and this limiting mechanism is used to make the second transmission member 363 slide from the first chute 211 into the second chute 212 when the rotation direction of the adjustment shaft 21 is changed.

[0036] When the adjusting shaft 21 rotates forward, the second transmission member 363 slides in the first chute 211 located at the bottom of the adjusting shaft 21. When the adjusting shaft 21 rotates in reverse, the second transmission member 363 slides from the first chute 211 into the second chute 212 under the drive of the limiting mechanism and slides along the second chute 212. At this time, the adjusting sleeve 36 rises along its axis under the drive of the second transmission member 363 and drives the mounting disc 31 to rotate by a certain angle. When the second transmission member 363 slides from the second chute 212 into the first chute 211 located at the top of the adjusting shaft 21, it continues to slide in this first chute 211, and the adjusting sleeve 36 stops rising.

[0037] When the adjusting shaft 21 rotates forward again, the second transmission member 363 slides from the first chute 211 located at the top of the adjusting shaft 21 into the second chute 212 under the drive of the limiting mechanism and continues to slide along the second chute 212, and finally slides into the first chute 211 located at the bottom of the adjusting shaft 21. At the same time, during the process of the second transmission member 363 sliding along the second chute 212, it drives the adjusting sleeve 36 to descend along its axis.

[0038] Reference Figure 8 and Figure 9 As shown in

[0039] There are two second chutes 212 and two second transmission members 363, and they are evenly distributed along the circumferential direction of the adjusting shaft 21. The two limiting mechanisms are symmetrically arranged with the midpoint between the two receiving grooves 213 as the center. The limiting mechanism includes two sliders 214 located in the receiving groove 213 and capable of sliding in the left-right direction. An elastic member 216 is fixedly installed between the ends of the two sliders 214 close to each other, and the elastic member 216 is a spring. The other ends of the two sliders 214 are both fixedly installed with limiting blocks 215, and the ends of the two limiting blocks 215 away from the sliders 214 both slide through the adjusting shaft 21 and extend into the corresponding first chute 211.

[0039] One side wall of the limiting block 215 is designed as an arc surface, and this arc surface is adapted to the side wall of the second chute 212; while the other side wall of the limiting block 215 is an inclined surface, and the inclination direction of this inclined surface is consistent with the extension direction of the first chute 211.

[0040] When the adjusting shaft 21 rotates forward, the second transmission member 363 slides in the first chute 211 located at the bottom of the adjusting shaft 21. When the second transmission member 363 slides to the inclined surface of the limiting block 215, it continues to slide along this inclined surface, and at this time the limiting block 215 is pressed into the receiving groove 213. When the adjusting shaft 21 rotates in reverse, the second transmission member 363 slides to the arc surface of the limiting block 215 and smoothly slides into the second chute 212 under the guiding action of this arc surface.

[0041] When the second transmission member 363 slides within the first sliding groove 211 located at the top of the adjustment shaft 21, since the limiting blocks 215 corresponding to the two first sliding grooves 211 are arranged in central symmetry, when the adjustment shaft 21 rotates in the reverse direction, the second transmission member 363 can slide within the first sliding groove 211 without obstruction. When the adjustment shaft 21 rotates forward again, the second transmission member 363 will slide from the first sliding groove 211 into the second sliding groove 212 under the action of the arc surface of the limiting block 215. In this way, the up-and-down reciprocating sliding of the adjustment sleeve 36 along its axial direction can be achieved.

[0042] Reference Figure 1 and Figure 5 As shown in the figure, the filtering assembly 4 includes a filter screen 41 located above the partition assembly 3, and the filter screen 41 is fixedly installed on the inner wall of the reaction tower 1. Above the filter screen 41, there is a scraping mechanism for preventing the filter screen 41 from being blocked.

[0043] The scraping mechanism includes a transmission sleeve 42 fixedly sleeved on the outer wall at the top of the adjustment shaft 21. A plurality of scraping plates 43 are fixedly installed on the outer wall of the transmission sleeve 42, and these scraping plates 43 are evenly distributed along the circumferential direction of the transmission sleeve 42. The scraping plates 43 extend in the radial direction of the transmission sleeve 42, and the end of the scraping plate 43 away from the transmission sleeve 42 is in sliding contact with the inner wall of the reaction tower 1. In order to discharge the materials accumulated on the filter screen 41, a tower door 16 is provided on the side wall of the reaction tower 1.

[0044] Reference Figure 7 As shown in the figure, on both sides of the inner side wall of the transmission sleeve 42, there are clamping sliding grooves 421 extending in the radial direction thereof, and further at the bottom of the clamping sliding grooves 421, there are connecting sliding grooves 423 extending in the axial direction of the transmission sleeve 42. A clamping block 422 is slidably installed in the clamping sliding grooves 421, and a pressing block 424 is slidably installed in the connecting sliding grooves 423. The bottom of the pressing block 424 slides through the transmission sleeve 42 and extends outwards for a certain distance, and its top is designed as an inclined surface that gradually slopes upwards from the side close to the adjustment shaft 21 to the other side. The end of the clamping block 422 away from the adjustment shaft 21 is designed as an inclined surface that cooperates with the inclined surface of the pressing block 424.

[0045] When the adjusting sleeve 36 rises, it will push the part of the pressing block 424 extending out of the driving sleeve 42 into the connecting sliding groove 423. At this time, under the interaction of the inclined surface at the top of the pressing block 424 and the inclined surface of the clamping block 422, the pressing block 424 will drive the clamping block 422 to slide towards the adjusting shaft 21 and tightly contact it. In this state, the driving sleeve 42 will rotate synchronously and reversely with the adjusting shaft 21 under the action of the clamping block 422, thereby driving the scraper 43 to scrape and wash the filter screen 41. When the adjusting sleeve 36 descends, the pressing block 424 will descend under the action of its own gravity. At this time, the clamping block 422 no longer receives the thrust from the pressing block 424, so it can no longer apply pressure to the adjusting shaft 21. In this way, the driving sleeve 42 can no longer rotate with the adjusting shaft 21.

[0046] The implementation principle of the embodiment of the present invention is as follows: During the wastewater treatment process, first, the wastewater is discharged into the reaction chamber at the top of the reaction tower 1, and chemical agents are added to form precipitates of heavy metal ions in the wastewater. At the same time, the driving member 11 is started to drive the transmission shaft 2 to rotate forward. At this time, the transmission shaft 2 stirs the wastewater through the stirring group 22, thereby accelerating the process of forming precipitates of heavy metal ions in the wastewater.

[0047] After the reaction is completed, the driving member 11 is controlled to drive the transmission shaft 2 to rotate reversely. As the transmission shaft 2 rotates, it simultaneously drives the adjusting shaft 21 to rotate reversely. At this time, under the guidance of the arc surface of the limiting block 215, the second transmission member 363 slides from the first sliding groove 211 at the bottom of the outer wall of the adjusting shaft 21 into the second sliding groove 212 and continues to slide upward along the second sliding groove 212. This movement causes the adjusting sleeve 36 to rise along its own axis under the push of the second transmission member 363. At the same time, as the adjusting sleeve 36 rises, the first transmission member 341 slides downward along the transmission groove 362, thereby driving the installation sleeve 34 to rotate. The rotation of the installation sleeve 34 causes the support plate 35 to rotate between the two sector plates 33. At this time, the support plate 35 can no longer support the sector plates 33. Therefore, the sector plates 33 rotate downward by 90 degrees with the rotation axis 32 as the center under the pressure of the wastewater above and their own gravity, thereby realizing the full opening of the partition assembly 3. In this way, the wastewater can fall into the precipitation chamber at the bottom of the reaction tower 1 for precipitation.

[0048] When the wastewater passes through the partition assembly 3, it will first flow through the filter screen 41 for filtration. When the adjusting sleeve 36 rises, it will push the clamping block 422 into the driving sleeve 42 and press the clamping block 422 against the outer wall of the adjusting shaft 21. At this time, under the action of the clamping block 422, the driving sleeve 42 will rotate synchronously with the adjusting shaft 21. This rotational movement then drives the scraper 43 to scrape and wash the filter screen 41, thereby preventing the filter screen 41 from being blocked by the precipitated impurities during filtration.

[0049] After all the wastewater enters the sedimentation chamber, control the driving member 11 to drive the transmission shaft 2 and the adjustment shaft 21 to rotate forward again. At this time, under the guidance of the arc surface of the limiting block 215, the second transmission member 363 slides from the first chute 211 at the top of the outer wall of the adjustment shaft 21 into the second chute 212 and slides downward along the second chute 212. This movement causes the adjustment sleeve 36 to descend along its own axis under the push of the second transmission member 363. At the same time, as the adjustment sleeve 36 descends, the first transmission member 341 slides upward along the transmission groove 362, thereby driving the installation sleeve 34 to rotate in the reverse direction. The reverse rotation of the installation sleeve 34 causes the support plate 35 to rotate in the reverse direction. As the support plate 35 rotates in the reverse direction, it drives the sector plate 33 to rotate upward by 90 degrees with the rotation shaft 32 as the axis, thus realizing the full closure of the partition assembly 3.

[0050] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention.
