Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device and treatment method. Background Technology

[0002] Wastewater typically refers to waste liquids containing various pollutants (such as suspended solids, organic matter, heavy metal ions, etc.) generated from industrial production, daily life, or other activities. If discharged directly without treatment, it will cause serious harm to water bodies and the ecological environment. Currently, wastewater treatment often uses devices such as stirred tanks to treat wastewater through physical, chemical, or biological methods to reduce the concentration of pollutants and make it meet the discharge or reuse standards.

[0003] In wastewater treatment, chemical agents are usually added to a stirred tank to transform pollutants. However, in actual operation, the fine particles formed after the agent and wastewater are mixed tend to settle and accumulate at the bottom of the tank. This accumulation can lead to insufficient local mixing intensity, preventing the agent and wastewater from fully contacting and reacting. Therefore, this application proposes a wastewater treatment device and treatment method. Summary of the Invention

[0006] Optionally, the execution component includes a transmission pipe, a recessed frame, a first connecting groove, a guide rod, a support pipe, a second connecting groove, a support rod, a side plate, and multiple sets of first inclined blocks. The transmission pipe is fixedly connected to the dispersion plate, the recessed frame is fixedly connected to the top of the scraper, and the transmission pipe slides through the recessed frame. The first connecting groove is opened on the outside of the transmission pipe, the guide rod is rotatably connected to the inside of the first connecting groove, and the end of the guide rod away from the transmission pipe is slidably connected to the top of the recessed frame. The support pipe is slidably connected to the inside of the transmission pipe, the second connecting groove is opened on the outside of the support pipe, the support rod is rotatably connected to the inside of the second connecting groove, and the end of the support rod away from the support pipe is fixedly connected to the top of the inner side of the recessed frame. The side plate is fixedly connected to the inner wall of the vessel body, and multiple sets of first inclined blocks are all fixedly connected to the bottom of the side plate. The top of the guide rod is flush with the top of the first inclined block.

[0007] Optionally, the reset assembly includes a fixing plate and a spring, the fixing plate being fixed to the outside of the guide rod, and the spring being fixed between the recess and the fixing plate.

[0008] Optionally, a traction rope is fixedly connected to the bottom end of the enclosure plate, and the end of the traction rope away from the enclosure plate is fixedly connected to the outside of the centrifugal rod.

[0009] Optionally, the rotating mechanism includes a spur gear three, a gear ring, four sets of locking rods, and four sets of locking slots. The spur gear three is fixed to the outside of the support tube, the gear ring is fixed to the inner wall of the vessel body, the spur gear three meshes with the gear ring, the four sets of locking rods are all fixed to the outside of the support tube, and the four sets of locking slots are all opened on the inner wall of the transmission tube. The locking rods and the locking slots are slidably connected inside.

[0010] Optionally, a rotating roller is rotatably connected to the outer side of the guide rod, and the rotating roller is in contact with the inclined block.

[0011] Optionally, a filter plate is slidably connected inside the water pumping pipe, and guide plates are fixedly connected to both sides of the filter plate. A limit rod slides through the inside of the guide plate, and both ends of the limit rod are fixedly connected to the inner wall of the water pumping pipe.

[0012] Optionally, a pressure plate is fixed to the outside of the stirring rod, and an inclined block two is provided around the pressure plate. A linkage rod is fixed to the bottom end of the inclined block two, and the end of the linkage rod away from the inclined block two is fixed to the top of the filter plate. A spring two is fixed to the bottom end of the guide plate, and the bottom end of the spring two is fixed to the inner wall of the water pumping pipe.

[0013] Optionally, a guide plate is fixed to the top of the connecting rod, and the guide plate has a tapered cross-section.

[0014] In a second aspect, the present invention provides a wastewater treatment method applied to the wastewater treatment apparatus described in the first aspect, the method comprising the following steps: S1. Start the motor to drive the stirring rod to rotate, which in turn drives the centrifugal rod to perform basic stirring of the wastewater and reagents in the reactor, while the scraper removes the adhering substances from the inner wall. S2. Start the water pump to pump the liquid at the bottom of the vessel into the stirring rod and spray it out from its outlet to achieve liquid circulation. At the same time, the rotation of the scraper drives the dispersing plate to reciprocate through the reciprocating mechanism, intermittently impacting the sprayed liquid flow to achieve particle crushing. During this process, the rotating mechanism drives the dispersing plate to rotate, generating rotational shear force, which further enhances the crushing and mixing effect. S3. The filter plate at the inlet of the water pump intercepts large particles. When the stirring rod rotates, the filter plate vibrates periodically through the cooperation of the pressure plate and the second inclined block, achieving self-cleaning and preventing clogging. S4. The above processes work together to ensure that the wastewater and the reagents are fully mixed and reacted, and the final treated liquid is discharged from the discharge port.

[0015] Compared with the prior art, this application includes at least one of the following beneficial technical effects: This invention significantly improves the mixing effect through the structural design of a circulating pressing mechanism and a reciprocating mechanism. The circulating pressing mechanism can draw liquid from the bottom of the vessel and spray it upward, causing the precipitated particles to circulate upward and effectively prevent sedimentation. The reciprocating mechanism drives the dispersing plate to move back and forth, intermittently and actively impacting the high-speed liquid flow, using stronger impact force to break up particle agglomerates. The combination of the two achieves enhanced treatment of particulate matter from the bottom to active crushing, making the reaction between the reagent and wastewater more complete and the mixing more uniform.

[0016] Furthermore, through the structural design of the rotating mechanism, the dispersing plate can generate a rotational motion around its own axis while reciprocating impact near the stirring rod. This rotational motion generates rotational shear force in the liquid, which, combined with the impact force generated by the linear impact of the dispersing plate, forms a composite action mode. This enhances the breaking, tearing, and diffusion effect on particulate matter and flocs in the liquid, thereby greatly promoting the micro-mixing of the reagent and wastewater and improving the overall reaction efficiency and treatment uniformity.

[0019] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0020] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0021] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 - Figure 5 As shown, the present invention proposes a wastewater treatment device, including a vessel body 1. The vessel body 1 has an inlet 3 at its top and a outlet 4 at its bottom. The inlet 3 is used to add chemicals and wastewater into the vessel body 1, and the outlet 4 is used to discharge the mixture of wastewater and chemicals. A motor 5 is installed at the top of the vessel body 1. After adding chemicals and wastewater into the vessel body 1, the motor 5 is started. The output end of the motor 5 is connected to a spur gear 6. When the motor 5 is running, its output end drives the spur gear 6 to rotate. A second spur gear 7 meshes with the outer side of the first spur gear 6, and the rotation of the first spur gear 6 drives the second spur gear 7 to rotate. A stirring rod 8, which is rotatably connected to the vessel body 1, is fixed inside the second spur gear 7. The rotation of the second spur gear 7 drives the stirring rod 8 to rotate. The wastewater treatment device also includes four sets of hinged components on the outer side of the stirring rod 8. Centrifugal rod 9, with centrifugal ball 91 fixed to the end away from stirring rod 8. In the initial state, centrifugal rod 9 and centrifugal ball 91 are close to the outside of stirring rod 8, providing space for workers to clean the inside of the vessel 1. When stirring rod 8 rotates, centrifugal ball 91 generates centrifugal force, which drives centrifugal rod 9 to swing and unfold. At this time, the position of centrifugal ball 91 changes and moves away from stirring rod 8, thereby better stirring the liquid inside the vessel 1 and mixing wastewater with the agent. Four sets of connecting rods 10 are also fixed to the outside of stirring rod 8, and when stirring rod 8 rotates, it will also drive the four sets of connecting rods 10 to rotate synchronously. Each of the four sets of connecting rods 10 has a scraper 11 fixed to the end away from stirring rod 8. When the connecting rods 10 rotate, they will drive the scraper 11 to move along the inner wall of the vessel 1, scraping off the adhering substances on the inner wall of the vessel 1.

[0023] As one implementation method, such as Figure 4 and Figure 5As shown, the wastewater treatment device also includes a circulating flushing mechanism, which includes a water pump 12, a water pumping pipe 13, a water outlet pipe 14, a connecting concave plate 15, a connecting ring 16, and four sets of water outlet holes 40. The circulating mechanism is described in detail below: The pump pipe 13 and the outlet pipe 14 are respectively connected to the input and output ends of the pump 12. The pump 12 is activated when the centrifugal rod 9 stirs and mixes the liquid inside the vessel 1. During operation, the pump 12 draws liquid from the bottom of the vessel 1 through the pump pipe 13, and then discharges the liquid into the stirring rod 8 through the outlet pipe 14. A connecting concave plate 15 is fixedly connected to the end of the outlet pipe 14 away from the pump 12. The connecting ring 16 is fixedly connected to the top of the stirring rod 8. The connecting concave plate 15 is rotatably connected to the outside of the connecting ring 16. When the stirring rod 8 rotates, it drives the connecting ring 16 to rotate synchronously. Because the connecting concave plate 15 and the connecting ring 16 are rotatably connected, the connecting ring 16 does not drive the connecting concave plate 15 to rotate when it rotates (e.g., ...). Figure 5 As shown in the figure, this ensures that the water outlet pipe 14 is always in a stationary state. All four sets of water outlet holes 40 are opened inside the stirring rod 8. The liquid inside the stirring rod 8 will eventually be sprayed out through the four sets of water outlet holes 40. During the process of liquid spraying out, it will also play a further role in mixing. At this time, the particles and liquid that have settled at the bottom inside the vessel 1 will circulate to the top inside the vessel 1, making it more evenly mixed and effectively solving the problem that the reagent and wastewater cannot fully contact each other.

[0024] Among them, such as Figure 2 and Figure 3 As shown, the wastewater treatment device also includes a self-sealing mechanism, which comprises a sealing plate 401 and a spring 402. In the initial state, the sealing plate 401, under the action of the elastic potential energy of the spring 402, seals the four sets of water outlet holes 40, thereby preventing dust from entering when not in use. The sealing plate 401 is slidably connected to the inside of the stirring rod 8. The two ends of the spring 402 are fixed to the inner walls of the sealing plate 401 and the stirring rod 8, respectively. When liquid enters the stirring rod 8 from top to bottom, the sealing plate 401 is subjected to liquid pressure and moves downwards, squeezing the spring 402, causing the spring 402 to deform under stress. It generates elastic potential energy. When the liquid flow ends, spring 3 402 releases the elastic potential energy, pushing the sealing plate 401 to move upward and reset, closing the four sets of water outlet holes 40 again. The bottom end of the sealing plate 401 is fixedly connected to a traction rope 92. The end of the traction rope 92 away from the sealing plate 401 is fixedly connected to the outside of the centrifugal rod 9. When the centrifugal rod 9 unfolds, it will also pull the sealing plate 401 downward through the traction rope 92. With the action of liquid pressure, the sealing plate 401 moves more smoothly, effectively avoiding the fact that the sealing plate 401 cannot overcome the elastic potential energy of spring 3 402 and the friction between it and the stirring rod 8 by hydraulic action alone.

[0025] Furthermore, such as Figure 5 - Figure 8 As shown, the wastewater treatment device also includes at least four sets of dispersing plates 17 for breaking up materials and a reciprocating mechanism. The reciprocating mechanism is located inside the vessel body 1 and includes an execution component and a reset component. The execution component is connected to the scraper 11 and is used to drive the dispersing plates 17 closer to the stirring rod 8, so that the dispersing plates 17 impact the material sprayed from the water outlet 40. When the scraper 11 rotates along the inner wall of the vessel body 1, the scraper 11 also drives the execution component to run. The running of the execution component will drive the dispersing plates 17 closer to the stirring rod 8. During the movement of the dispersing plates 17, they will come into contact with and collide with the liquid sprayed from the water outlet 40. The impact force generated by this collision can break up the particles in the wastewater. The material is crushed to facilitate thorough mixing of the reagent and wastewater. The impact force generated by the dispersing plate 17 striking the liquid is greater than that of the liquid directly sprayed from the outlet 40 striking the inner wall of the vessel body 1, resulting in a better crushing effect on the particulate matter. The reset component is used to drive the dispersing plate 17 to reset. After the scraper 11 moves a certain distance along the inner wall of the vessel body 1, the actuator releases the control of the dispersing plate 17, and the reset component will drive the dispersing plate 17 to reset and move away from the stirring rod 8. After the scraper 11 moves a certain distance, the actuator will control the dispersing plate 17 again, thereby repeating the above action, so that the dispersing plate 17 intermittently strikes the liquid sprayed from the outlet 40.

[0026] Furthermore, such as Figure 5 - Figure 9 As shown, the wastewater treatment device also includes a rotating mechanism connected to the actuator. The rotating mechanism is used to drive the dispersion plate 17 to rotate when it approaches the stirring rod 8. When the actuator moves together with the scraper 11, the actuator will also drive the rotating mechanism to run. The operation of the rotating mechanism will drive the dispersion plate 17 to rotate through the actuator. The rotation of the dispersion plate 17 will generate rotational friction when it comes into contact with the liquid. This rotational friction causes the dispersion plate 17 to generate significant tangential friction and circumferential agitation in the liquid, forming a rotating fluid shear force. Combined with the impact and disturbance force generated when the dispersion plate 17 moves, it can more effectively disperse and break up the particle agglomerates formed in the liquid, thereby significantly improving the mixing degree and reaction efficiency of wastewater and reagents.

[0027] As one implementation method, such as Figure 5 - Figure 9 As shown, the actuation component includes a transmission pipe 18, a recessed frame 41, a connecting groove 19, a guide rod 20, a support pipe 21, a connecting groove 22, a support rod 23, a side plate 24, and multiple sets of inclined blocks 25. The actuation component is described in detail below: The transmission pipe 18 is fixedly connected to the dispersion plate 17, and the recessed frame 41 is fixedly connected to the top of the scraper 11. When the scraper 11 moves, it will drive the recessed frame 41 to move synchronously. The transmission pipe 18 slides through the recessed frame 41 and can move along the inside of the recessed frame 41. The connecting groove 19 is opened on the outside of the transmission pipe 18, and the guide rod 20 is rotatably connected to the inside of the connecting groove 19. The opening of the connecting groove 19 ensures that the guide rod 20 is always in the same position on the outside of the transmission pipe 18. The guide rod 20 is away from the transmission pipe 18. One end of tube 18 is slidably connected to the top of recess 41. The support tube 21 is slidably connected to the inside of transmission tube 18. Transmission tube 18 can move along the outside of support tube 21. Connecting groove 22 is opened on the outside of support tube 21. Support rod 23 is rotatably connected to the inside of connecting groove 22. The opening of connecting groove 22 ensures that support rod 23 is always in the same position on the outside of support tube 21. The end of support rod 23 away from support tube 21 is fixedly connected to the top of the inner side of recess 41. Because support rod 23 and recess 41 are connected together... The inner wall of the frame 41 is fixed, therefore, the support rod 23 restricts the position of the support tube 21, so that the support tube 21 can only rotate along the inside of the support rod 23. When the scraper 11 moves the recessed frame 41, the support rod 23 will follow the movement of the recessed frame 41, causing the support tube 21 to move synchronously. The movement of the support tube 21 will cause the transmission tube 18 to move, and the movement of the transmission tube 18 will in turn drive the guide rod 20 to move synchronously. The side plate 24 is fixed to the inner wall of the vessel body 1, and multiple sets of inclined blocks 25 are fixed to the bottom end of the side plate 24. The top of the guide rod 20 is flush with the top of the inclined block 25. As the guide rod 20 continues to move, it will contact the inclined surface of the inclined block 25. Since the position of the inclined block 25 is fixed, the guide rod 20 will move along the inclined surface of the inclined block 25. The movement of the guide rod 20 will drive the transmission tube 18 to move along the outside of the support tube 21. The movement of the transmission tube 18 will drive the dispersion plate 17 to approach the stirring rod 8, so that the dispersion plate 17 will impact the liquid sprayed from the water outlet 40, breaking up the particles in the liquid.

[0028] Furthermore, such as Figure 7 , Figure 8 and Figure 9 As shown, the reset assembly includes a fixing plate 26 and a spring 27. The reset assembly is described in detail below: The fixed plate 26 is fixed to the outside of the guide rod 20. When the guide rod 20 moves, it also drives the fixed plate 26 to move towards the dispersion plate 17. The spring 27 is fixed between the recessed frame 41 and the fixed plate 26. When the fixed plate 26 moves, it will cooperate with the recessed frame 41 to compress the spring 27, causing the spring 27 to deform under force. When the guide rod 20 passes the inclined block 25, the spring 27 will stop being stressed and will release its elastic potential energy, pushing the fixed plate 26 to reset. The reset of the fixed plate 26 will then drive the transmission tube 18 to reset via the guide rod 20. When the transmission tube 18 resets, it will pull the dispersion plate 17 to reset, causing the dispersion plate 17 to move away from the stirring rod 8. This prepares the guide rod 20 to contact the lower inclined block 25, and the dispersion plate 17 to impact the liquid again. There are two sets of fixing plates 26 and springs 27, which are symmetrically distributed on both sides of the guide rod 20. The two sets of fixing plates 26 and springs 27 can replace one set of fixing plates 26 or springs 27 if one set is damaged, avoiding the need for downtime maintenance.

[0029] Furthermore, such as Figure 6 , Figure 8 and Figure 9 As shown, the rotating mechanism includes a spur gear 28, a gear ring 29, four sets of locking rods 30, and four sets of locking slots 31. The rotating mechanism is described in detail below: The spur gear 28 is fixedly connected to the outside of the support tube 21. When the support tube 21 moves along the inner wall of the vessel body 1, the support tube 21 will drive the spur gear 28 to move synchronously. The gear ring 29 is fixedly connected to the inner wall of the vessel body 1. The spur gear 28 meshes with the gear ring 29. When the spur gear 28 moves, it will roll along the gear ring 29, causing the spur gear 28 to rotate. The rotation of the spur gear 28 will drive the support tube 21 to rotate. All four sets of clamping rods 30 are fixedly connected to the outside of the support tube 21. When the support tube 21 rotates, it will drive the four sets of clamping rods 30 to make circular motion around the axis of its support tube 21. The four sets of clamping grooves 31 are all opened on the inner wall of the transmission tube 18. The clamping rods 30 are slidably connected to the inside of the clamping grooves 31. Correspondingly, the inner wall of the transmission tube 18 is provided with four sets of clamping grooves 31 that match the clamping rods 30. When the clamping rods 30 rotate with the axis of the support tube 21, the clamping rods 30 will drive the transmission tube 18 to rotate around its own axis through the clamping grooves 31, thereby providing continuous and stable rotational power for the dispersion plate 17.

[0030] As one implementation method, such as Figure 9As shown, a rotating roller 32 is rotatably connected to the outer side of the guide rod 20. The rotating roller 32 is in contact with the inclined block 25. The rotating roller 32 is designed to contact the inclined block 25 before the guide rod 20 contacts it. The rotating roller 32 can rotate along the inclined surface of the inclined block 25, thereby reducing friction and improving the service life of the device.

[0031] Furthermore, such as Figure 10 and Figure 11 As shown, a filter plate 33 is slidably connected inside the water pump 13. The filter plate 33 has a large internal channel, which allows it to isolate large particles that need to be cleaned later, while not isolating small particles that need to be crushed and mixed. This prevents large particles from entering the water pump 12 and causing damage. Guide plates 34 are fixedly connected to both sides of the filter plate 33. Limiting rods 35 slide through the interior of the guide plates 34, and both ends of the limiting rods 35 are fixedly connected to the inner wall of the water pump 13. The filter plate 33 can move up and down along the outer side of the limiting rod 35 via the guide plate 34. The limiting rod 35 limits the movement of the filter plate 33, preventing it from shaking during its up-and-down movement. A pressure plate 36 is fixedly connected to the outer side of the stirring rod 8. When the stirring rod 8 rotates, it drives the pressure plate 36 to rotate along the axis of the stirring rod 8. An inclined block 37 is provided around the periphery of the pressure plate 36. During its movement, the pressure plate 36 contacts the inclined surface of the inclined block 37 and applies downward pressure to it. Force is applied to the bottom end of the inclined block 37, which is fixedly connected to a linkage rod 38. When the inclined block 37 is subjected to force, it drives the linkage rod 38 to move downward. The end of the linkage rod 38 away from the inclined block 37 is fixedly connected to the top end of the filter plate 33. The downward movement of the linkage rod 38 will cause the filter plate 33 to move downward. A spring 39 is fixedly connected to the bottom end of the guide plate 34. The bottom end of the spring 39 is fixedly connected to the inner wall of the water suction pipe 13. When the filter plate 33 moves downward, it will compress the spring 39 through the guide plate 34, causing the spring 39 to deform under force. The spring 39 generates elastic potential energy, and after the pressure plate 36 passes the inclined block 37, the spring 39 will release the elastic potential energy instantly, pushing the guide plate 34 to move upward and reset. The upward movement of the guide plate 34 will drive the filter plate 33 to move upward. When the guide plate 34 moves to the limit position, it will collide with the inner wall of the water pipe 13, thereby generating vibration force. The vibration force generated is effectively transmitted to the filter plate 33, which can shake off the fine particles attached or accumulated in its channel, thereby achieving the self-cleaning function and keeping the filter channel of the filter plate 33 unobstructed for a long time.

[0032] In addition, such as Figure 6 As shown, a guide plate 42 is fixed to the top of the connecting rod 10. The cross-section of the guide plate 42 is tapered. The tapered design of the guide plate 42 can prevent liquid or fine particles from accumulating at the top of the connecting rod 10. The liquid or particles will fall down along the inclined surface of the recess 41.

[0033] A wastewater treatment method, the method comprising the following steps: S1. Start motor 5 to drive stirring rod 8 to rotate, which drives centrifugal rod 9 to perform basic stirring of wastewater and reagent in the vessel 1, while scraper 11 removes the attached substances from the inner wall. S2. Start the water pump 12 to pump the liquid at the bottom of the vessel 1 into the stirring rod 8 and spray it out from its outlet 40 to achieve liquid circulation. At the same time, the rotation of the scraper 11 drives the dispersing plate 17 to reciprocate through the reciprocating mechanism, intermittently impacting the sprayed liquid flow to achieve particle crushing. In this process, the rotating mechanism drives the dispersing plate 17 to rotate, generating rotational shear force, which further enhances the crushing and mixing effect. S3, the filter plate 33 at the inlet of the water pipe 13 intercepts large particles. When the stirring rod 8 rotates, the filter plate 33 is periodically driven to vibrate through the cooperation of the pressure plate 36 and the inclined block 37, so as to achieve self-cleaning and prevent clogging. S4. The above processes work together to ensure that the wastewater and the reagents are fully mixed and reacted, and the final treated liquid is discharged from the discharge port 4.

[0034] In this embodiment, wastewater and chemicals are first added into the vessel 1 through the feed inlet 3. The motor 5 is started, and the output end of the motor 5 drives the spur gear 6 to mesh with the transmission spur gear 7, causing the stirring rod 8 fixed therein to rotate. The stirring rod 8 drives the centrifugal rod 9 and centrifugal ball 91 on the outside to expand due to centrifugal force, and initially stirs the liquid in the vessel 1. At the same time, the connecting rod 10 drives the scraper 11 to rotate along the inner wall of the vessel 1 to scrape off the attached substances. The conical guide plate 42 fixed to the top of the connecting rod 10 prevents the material from accumulating. Meanwhile, the water pump 12 is started, and the liquid at the bottom of the vessel 1 is drawn through the water pipe 13 and sent into the stirring rod 8 through the water outlet pipe 14. The stirring rod 8 is rotatably connected by the connecting concave plate 15 and the connecting ring 16. In the initial state, the sealing plate 401 closes the water outlet 40 under the action of the spring 3 402. When the liquid pressure overcomes the elastic force of the spring 3 402 and the centrifugal rod 9 is pulled down by the traction rope 92, the sealing plate 401 moves down and opens the water outlet 40, and the liquid sprays out to achieve up and down circulation. When the scraper 11 moves, it drives the recessed frame 41, causing the guide rod 20 to move along the inclined surface of the inclined block 25 at the bottom of the side plate 24. This, through the transmission tube 18, pushes the dispersion plate 17 closer to the stirring rod 8 to impact the sprayed liquid flow and break the particles. During this process, the support tube 21 moves with the recessed frame 41, and its outer spur gear 28 rolls and rotates along the toothed ring 29 on the inner wall of the vessel body 1. The clamping rod 30 engages with the groove 31 on the inner wall of the transmission tube 18, driving the dispersion plate 17 to rotate, generating rotational shear force to enhance the crushing effect. When the guide rod 21 moves, the guide rod 20 moves along the inclined surface of the side plate 24. As the stirring rod 20 passes over the inclined block 25, the spring 27 pushes the fixing plate 26 to reset the dispersing plate 17, and the rotating roller 32 contacts the inclined surface to reduce friction. In addition, when the stirring rod 8 rotates, it drives the pressure plate 36 to periodically press down the inclined block 37, and pushes the filter plate 33 to compress the spring 39 through the linkage rod 38. After the pressure plate 36 passes over, the spring 39 rebounds and causes the filter plate 33 to hit the water pumping pipe 13 to generate vibration and achieve self-cleaning, ensuring smooth circulation, thereby completing the wastewater treatment process of efficient mixing and crushing.
