[0038] In addition, if Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a receiving groove 10 is provided inside the sieve plate 601, and the receiving groove 10 passes through the upper and lower end surfaces of the sieve plate 601. In addition, a receiving cylinder 11 is provided below the receiving groove 10, and the receiving cylinder 11 is fixedly connected to the bottom of the sieve plate 601, and the cylinder wall of the receiving cylinder 11 is also set to the material of the sieve plate 601. In addition, the other end of the receiving cylinder 11 is fixedly connected to the outer wall of the kettle body 1, and one end of the receiving cylinder 11 passes through the outer wall of the kettle body 1, so that the staff can take out the flocculants inside the receiving cylinder 11 from the outside of the kettle body 1 for collection, and a pumping cylinder 12 is also provided inside the receiving cylinder 11, and the interior of the pumping cylinder 12 is connected to the collecting chamber 602 through the receiving groove 10, and the cylinder wall of the pumping cylinder 12 is also set The material of the sieve plate 601 makes the suction tube 12 also have a filtering function, and the other end of the suction tube 12 extends to the outside of the kettle body 1, and the end of the suction tube 12 extending to the outside of the kettle body 1 is also fixedly provided with a sealing plate 13, and the sealing plate 13 is detachably connected to the outer wall of the kettle body 1, so that when the spiral shaft 632 rotates, the cleaning component 9 can clean the floccules on the sieve plate 601, and clean the floccules into the inside of the storage tank 10, and enter the inside of the suction tube 12 from the storage tank 10, and then the staff can remove the sealing plate 13 later, draw out the suction tube 12 to remove the floccules, and the movement of the cleaning component 9 can clean the sieve plate 601 to prevent the sieve plate 601 from being blocked and affecting the filtration;

[0039] like Figure 1 and Figure 3As shown, the stirring assembly 4 is specifically configured to include an outer sleeve shaft 401, a connecting rod 402, a stirring shaft 403 and a stirring paddle 404, wherein the outer sleeve shaft 401 is sleeved on one end of the bottom end of the spiral shaft 632, and the outer sleeve shaft 401 is sleeved on one end of the spiral shaft 632 located outside the outer tube 631, and the outer wall of the outer sleeve shaft 401 is fixedly provided with a connecting rod 402, one end of the connecting rod 402 is fixedly provided with a stirring shaft 403, and the outer wall of the stirring shaft 403 is fixedly provided with a stirring paddle 404, so that when the spiral shaft 632 rotates The outer sleeve shaft 401 is driven to rotate, and the outer sleeve shaft 401 drives the connecting rod 402 and the stirring shaft 403 to move with the spiral shaft 632 as the center, so that the stirring paddle 404 moves around the spiral shaft 632 as the center, thereby stirring the inside of the kettle body 1.

[0040] Considering that after the flocculant is stirred and mixed, it needs to be precipitated so that the flocs can be precipitated at the bottom of the kettle body 1, and when the flocs are lifted to the inside of the collection chamber 602 by the lifting assembly 603, the rotation of the stirring shaft 403 will cause the precipitated flocs to be redispersed inside the kettle body 1, thereby affecting the collection of the flocs. Therefore, if Figure 1 , Figure 3 and Figure 7 As shown, the outer sleeve shaft 401 is configured to be rotatably sleeved on the outside of the screw shaft 632, and the outer sleeve shaft 401 can only rotate circumferentially outside the screw shaft 632 but cannot move longitudinally. The screw shaft 632 and the outer sleeve shaft 401 are transmission-connected by arranging a linkage assembly 14, so that the transmission connection between the screw shaft 632 and the outer sleeve shaft 401 can be connected or disconnected, and thus the stirring shaft 403 can be controlled to remain stationary when the screw shaft 632 rotates to lift and transport;

[0041] like Figure 1 , Figure 6 and Figure 7As shown, the linkage assembly 14 specifically includes a switching drive assembly 141 and a clamping assembly 142, wherein the switching drive assembly 141 is arranged at the bottom of the kettle body 1, and the driving of the switching drive assembly 141 is controlled by the rotation speed of the screw shaft 632, and the clamping assembly 142 is used to clamp the screw shaft 632 with the outer sleeve shaft 401, and the switching drive assembly 141 and the clamping assembly 142 are set to a linkage state, the switching drive assembly 141 is used to drive the clamping assembly 142, when the screw shaft 632 rotates at a high speed for stirring, the clamping assembly 142 is started, so that the screw shaft 632 and the outer sleeve The outer sleeve shaft 401 is connected, and the spiral shaft 632 rotates to drive the outer sleeve shaft 401 to rotate at a high speed, so that the outer sleeve shaft 401 drives the stirring shaft 403 to rotate, and then the stirring paddle 404 moves to stir and mix. When the spiral shaft 632 is lifting, the speed of the spiral shaft 632 is reduced, and the spiral shaft 632 does not need to rotate at a high speed. The clamping assembly 142 is closed, so that the spiral shaft 632 is disconnected from the outer sleeve shaft 401, and then when the floccules are lifted, the stirring shaft 403 is stationary and cannot rotate, so as to avoid the movement of the stirring paddle 404 affecting the precipitation of the floccules, so that the floccules are redispersed in the wastewater;

[0042] More specifically, Figure 1 , Figure 6-Figure 11As shown, the switching drive assembly 141 is configured to be started by the centrifugal force generated when the spiral shaft 632 rotates at a high speed. The switching drive assembly 141 includes a connecting chamber 1411, a connecting column 1412, a sliding hole 1413, a through hole 1414, a sliding plate 1415, a sliding rod 1416, a centrifugal ball 1417 and a connecting rope 1418, wherein the bottom of the kettle body 1 is fixedly provided with a connecting chamber 1411, and the bottom end of the spiral shaft 632 passes through the bottom wall of the kettle body 1 and extends to the inside of the connecting chamber 1411, and the spiral shaft 632 is rotatably sealed and connected with the bottom wall of the kettle body 1, and the outer wall of the spiral shaft 632 located inside the connecting chamber 1411 is fixedly provided with a connecting column 1412, and the connecting column 1412 is transversely arranged on the spiral shaft 632 and perpendicular to each other, and a sliding hole 1413 is opened inside the connecting column 1412, and a through hole 1414 is opened at one end of the sliding hole 1413.

When the screw shaft 632 rotates at a high speed, the rotation of the screw shaft 632 will cause the centrifugal ball 1417 to move away from the screw shaft 632 through centrifugal force, and then the movement of the centrifugal ball 1417 can drive the sliding plate 1415 to move through the sliding rod 1416, and then drive the clamping assembly 142 to start clamping with the outer sleeve shaft 401 through the connecting rope 1418;

[0043] The clamping assembly 142 specifically includes a limiting slide 1421, a clamping slide 1422, a clamping hole 1423, a slider 1424, a moving block 1425, a clamping rod 1426 and a connecting hole 1427, wherein the limiting slide 1421 is provided inside the bottom of the spiral shaft 632, and the limiting slide 1421 is provided with a limiting slide 1421 in the circumferential direction, and at least two limiting slides 1421 are provided. In this embodiment, limiting slides 1421 are respectively provided on both sides of the limiting slide 1421. A snap-in hole 1423 is provided on one side of 1421, and the snap-in hole 1423 penetrates the outer wall of the spiral shaft 632, a slider 1424 is provided inside the limiting slide groove 1421 for longitudinal sliding, the outer wall of the slider 1424 fits and slides with the inner wall of the limiting slide groove 1421, and a moving block 1425 is provided inside the snap-in slide groove 1422 for transverse sliding, a snap-in rod 1426 is provided inside the snap-in hole 1423 for sliding, and the snap-in rod 1426 is fixedly connected to the moving block 1425, and the outer sleeve shaft 401 is connected to the snap-in A connecting hole 1427 is provided at a position corresponding to the hole 1423, and the clamping rod 1426 is plugged into the connecting hole 1427. In addition, it should be noted that the side of the moving block 1425 facing the limiting slide groove 1421 is set as an inclined surface, and the inclined surface is inclined from top to bottom. Specifically, the moving block 1425 is wide at the bottom and narrow at the top, and the moving block 1425 is provided with a spring 16 toward the clamping rod 1426, and the spring 16 is sleeved on the outer wall of the clamping rod 1426, and one end of the spring 16 is in contact with the moving block 1425. , the other end contacts the inner wall of the clamping slide groove 1422, and the moving block 1425 is rebounded toward the slider 1424 through the spring 16, and the bottom of the slider 1424 is also fixedly provided with a positioning block 17, and a spring tube 19 is provided below the positioning block 17, and the spring tube 19 is fixedly provided with the bottom wall of the limiting slide groove 1421, and a spring 2 18 is provided inside the spring tube 19, and the top of the spring 2 18 contacts the positioning block 17. After the centrifugal force disappears or decreases, the slider 1424 is rebounded upward by the spring 2 18;

[0044] The size of the clamping assembly 142 is configured such that when the slider 1424 moves downward, the slider 1424 can move the moving block 1425 toward the inside of the clamping slot 1422 through the inclined surface at one end of the moving block 1425, so that the moving block 1425 drives the clamping rod 1426 to move toward the outside of the spiral shaft 632, and the clamping rod 1426 is inserted into the connection hole 1427 on the inner wall of the outer sleeve shaft 401, thereby achieving clamping. At the same time, the downward movement of the slider 1424 will compress the spring 18 below, and the spring tube 19 can limit the downward movement of the slider 1424. When the slider 1424 moves upward, it moves to the top surface and contacts the top wall of the limiting slide groove 1421, and the slider 1424 will separate from the moving block 1425. Without the limitation of the slider 1424, the moving block 1425 moves toward the limiting slide groove 1421 through the rebound of the spring 16, and one side of the moving block 1425 contacts the positioning block 17. At the same time, one end of the clamping rod 1426 will separate from the connecting hole 1427 of the outer sleeve shaft 401, and the clamping rod 1426 will move to the inside of the clamping hole 1423, thereby disconnecting from the outer sleeve shaft 401 and failing to drive the stirring shaft 403 to rotate.

[0045] And as Figure 7 and Figure 8As shown, the downward movement of the slider 1424 is controlled by the connecting rope 1418. A clearance hole 15 is opened below the limiting slide groove 1421, and the limiting slide groove 1421 is connected with the slide hole 1413 through the clearance hole 15. The connecting rope 1418 is arranged inside the clearance hole 15. The two ends of the connecting rope 1418 are respectively connected to the bottom end of the positioning block 17 and one end of the slide plate 1415. Then, when the wastewater is treated, the flocculant is first added into the kettle body 1, and then stirred. The motor assembly 5 drives the screw shaft 632 to rotate at a high speed to perform stirring. When the screw shaft 632 rotates at a high speed, the centrifugal ball 1417 moves through the centrifugal force, and then the centrifugal ball 1417 drives the slide bar 1416 and the slide plate 1415 to move. The slide plate 1415 pulls the positioning block 17 down through the connecting rope 1418, and the positioning block 17 causes the slider 1424 to move downward. The slider 1424 can move the moving block 1425 toward the clamping slide groove 1424 through the inclined surface at one end of the moving block 1425. 2, so that the moving block 1425 drives the clamping rod 1426 to move toward the outside of the spiral shaft 632, and the clamping rod 1426 is inserted into the connection hole 1427 on the inner wall of the outer sleeve shaft 401, thereby realizing clamping. The outer sleeve shaft 401 rotates to drive the stirring shaft 403 to move, so that the stirring paddle 404 moves to stir the wastewater and the flocculant. After the stirring is completed, the motor assembly 5 is turned off to allow the flocculants to settle. When the flocculants at the bottom need to be transferred to the inside of the collection chamber 602, the motor assembly 5 is started to slow down the speed of the motor assembly 5. When the motor speed slows down, the speed of the spiral shaft 632 cannot provide enough centrifugal force to allow the centrifugal ball 1417 to drive the slider 1424 to move downward, and then the clamping rod 1426 cannot be inserted into the inside of the connection hole 1427. The rotation of the spiral shaft 632 cannot drive the outer sleeve shaft 401 to rotate, thereby preventing the stirring shaft 403 from rotating to cause the precipitated flocculants to be dispersed again in the wastewater and affect the flocculant collection work.

[0046] The principle of the present invention is as follows: when the present invention is treating wastewater, the flocculant is first added to the inside of the kettle body 1, and then stirring is performed. The motor assembly 5 drives the spiral shaft 632 to rotate at a high speed to perform stirring. When the spiral shaft 632 rotates at a high speed, the centrifugal ball 1417 is moved by centrifugal force, and then the centrifugal ball 1417 drives the sliding rod 1416 and the sliding plate 1415 to move. The sliding plate 1415 pulls the positioning block 17 down through the connecting rope 1418, and the positioning block 17 causes the sliding block 1424 to move down. The sliding block 1424 can move the moving block 1425 toward the inside of the card-connecting groove 1422 through the inclined surface at one end of the moving block 1425, so that the moving block 1425 drives the card-connecting rod 1426 to move toward the outside of the spiral shaft 632, and the card-connecting rod 1426 is inserted into the inner wall of the outer sleeve shaft 401 The outer sleeve shaft 401 rotates to drive the stirring shaft 403 to move, so that the stirring paddle 404 moves to stir the wastewater and flocculant. After the stirring is completed, the motor assembly 5 is turned off to allow the flocculants to settle. When the flocculants at the bottom need to be transferred to the inside of the collecting chamber 602, the motor assembly 5 is started to slow down the speed of the motor assembly 5. When the motor speed slows down, the speed of the spiral shaft 632 cannot provide enough centrifugal force to allow the centrifugal ball 1417 to drive the slider 1424 to move downward, and then the clamping rod 1426 cannot be inserted into the connecting hole 1427. The rotation of the spiral shaft 632 cannot drive the outer sleeve shaft 401 to rotate, thereby preventing the stirring shaft 403 from rotating to cause the precipitated flocculants to be redispersed in the wastewater and affect the flocculant collection work.
