Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] This embodiment provides a multi-stage solid-liquid precipitation separation device for chemical production. The multi-stage solid-liquid precipitation separation refers to a process in which the device achieves solid-liquid separation through multiple steps or stages. Based on the provided text, these "stages" or steps can be understood as the following two main parts, which together constitute the multi-stage solid-liquid precipitation separation process:

[0031] Filtration mechanism: This is the first stage of separation. Wastewater is first filtered through the filter cylinder inside the filter housing. The bottom of the filter cylinder is a filter screen, which is used to initially separate solid particles in the wastewater.

[0032] Sedimentation and separation mechanism: This is the second stage of separation. The wastewater, after preliminary filtration, enters the sedimentation shell through a transfer pipe. Inside the sedimentation shell, the wastewater mixes with flocculant. The rotation of the smoothing blades accelerates the full integration of the wastewater and flocculant, causing impurities in the wastewater to form flocs, which then precipitate out of the aqueous phase under gravity.

[0033] This embodiment provides a multi-stage solid-liquid precipitation separation device for chemical production, as shown in the attached diagram. Figure 1 - Appendix Figure 7 The filter housing 1 includes a filter housing 1, a feed pipe 3 is fixedly connected to the bottom of the filter housing 1, the feed pipe 3 is connected to the sedimentation housing 18 through a transfer pipe 7, the filter housing 1 is provided with a filter mechanism, and the sedimentation housing 18 is provided with a sedimentation separation mechanism.

[0034] The structure of the filtration mechanism is as follows: Figure 4 , 5 6, 7, including a filter cylinder 36, the bottom of which is a filter screen. The filter cylinder 36 is located inside the filter housing 1. Connecting blocks 38 are fixedly provided on both sides of the filter cylinder 36. The connecting blocks 38 are fixedly connected to the inner wall of the filter housing 1. Two connecting rods 39 are connected to the top of the filter cylinder 36 through bearings. Two third gears 40 are fixedly sleeved on the outside of the two connecting rods 39. A fixing rod 41 is fixedly connected to the top of the filter cylinder 36. Multiple rotating sleeves 42 are sleeved on the outside of the fixing rod 41 through bearings. A fourth gear 43 is fixedly sleeved on the outside of the multiple rotating sleeves 42. The fourth gear 43 meshes with the third gear 40. Two connecting strips 44 are fixedly provided on one side of the rotating sleeves 42. Two connecting strips 44 are fixedly provided on one side of the two connecting strips 44. A push plate 45 has a through groove 46 at its lower part. A fifth gear 52 is fixedly installed at one end of each of the two connecting rods 39. A side frame 47 is fixedly installed on one side of the filter cylinder 36. A third motor 48 is fixedly installed on one side of the side frame 47. A connecting plate 49 is fixedly connected to the output end of the third motor 48. A sliding column 50 is connected to one side of the connecting plate 49 through a bearing. A slide rail frame 51 is provided on one side of the filter cylinder 36. The sliding column 50 extends into the long groove inside the slide rail frame 51. Tooth plates 55 are fixedly installed on both sides of the slide rail frame 51. The two tooth plates 55 mesh with the two fifth gears 52 respectively. A slag discharge plate 37 is fixedly installed on both sides of the filter cylinder 36. The slag discharge plate 37 is fixedly connected between the inner wall of the filter housing 1 and the filter cylinder 36.

[0035] Both sides of the filter housing 1 are provided with slag discharge ports 4, and both sides of the filter housing 1 are fixedly provided with slag discharge shells 5. Solid particles slide on the slag discharge plate 37 and pass through the slag discharge ports 4. The solid particles fall into the slag discharge shell 5 and are discharged through the opening at the bottom of the slag discharge shell 5. A conveyor belt can be set at the bottom of the slag discharge shell 5 for conveying.

[0036] In this embodiment, wastewater falls inside the filter cylinder 36, where solid particles in the wastewater are filtered. During the filtration process, the third motor 48 is started, controlling the connecting plate 49 to rotate. The connecting plate 49 drives the sliding column 50 to rotate, and the sliding column 50 slides within the slide rail frame 51, pushing the slide rail frame 51 to reciprocate. The slide rail frame 51 reciprocates, pushing the toothed plate 55 to reciprocate. The toothed plate 55 drives the fifth gear 52 to rotate clockwise by a certain angle and then counterclockwise, causing the fifth gear 52 to drive the connecting rod 39 to rotate. 9 drives the third gear 40 to rotate, the third gear 40 drives the fourth gear 43 to rotate, the fourth gear 43 drives the rotating sleeve 42 to rotate, and the rotating sleeve 42 drives the connecting bar 44 and the push plate 45 to make a pendulum motion. When two push plates 45 swing counterclockwise, the other two push plates 45 will swing clockwise. The push plates 45 push the wastewater in the filter cylinder 36. The wastewater passes through the through groove 46, thereby preventing the filter screen from clogging and accelerating the filtration of wastewater. At the same time, the push plates 45 push the solid particles in the wastewater out of the filter cylinder 36. The solid particles fall and slide along the slag discharge plate 37 into 5.

[0037] To facilitate sliding, the device employs the following technical solution: two side sliding grooves 53 are provided on one side of the filter cylinder 36, and side sliders 54 are fixedly provided on one side of each of the two toothed plates 55. The side sliders 54 extend into the side sliding grooves 53 and slide inside the side sliding grooves 53. The side sliders 54 slide inside the side sliding grooves 53, thereby limiting the toothed plates 55 and preventing the toothed plates 55 from tilting.

[0038] To achieve the purpose of sedimentation separation, this device adopts the following technical solution: The sedimentation separation mechanism includes a connecting frame 8, which is fixedly mounted on the top of the sedimentation shell 18. A second motor 22 is fixedly mounted on the top of the connecting frame 8. A lead screw 9 is fixedly connected to the output end of the second motor 22. The other end of the lead screw 9 is connected to the top of the sedimentation shell 18 via a bearing. The lead screw 9 passes through the connecting frame 8 and is connected to the connecting frame 8 via a bearing. A sliding plate 10 is threaded onto the outside of the lead screw 9. A limiting rod 23 is fixed between the connecting frame 8 and the sedimentation shell 18. The limiting rod 23 passes through the sliding plate 10 and is slidably connected to the sliding plate 10. A square shell 11 is provided on one side of the sliding plate 10. The connection between the sliding plate 10 and the square shell 11 is connected via a bearing. An inner tube 24 is connected to the inside of the square shell 11 via a bearing. A support tube 27 is connected to the top of the sedimentation shell 18 via a bearing. A first gear 15 is fixedly mounted on the top of the support tube 27. The square shell 11 passes through the first gear 15 and is slidably connected to the first gear 15. A support is fixedly mounted on the top of the sedimentation shell 18. The support frame 13 has a first motor 14 fixedly mounted on its top. A drive shaft 25 is fixedly connected to the output end of the first motor 14. One end of the drive shaft 25 is connected to the top of the sedimentation shell 18 via a bearing. The drive shaft 25 passes through the support frame 13 and is connected to it via a bearing. A second gear 26 is fixedly sleeved on the outside of the drive shaft 25, meshing with the first gear 15. Smoothing blades 34 are fixedly mounted on both sides of the square shell 11, and a scraper 35 is fixedly mounted between the two smoothing blades 34. The inner tube 2... 4. A filter plate 32 is fixedly provided at the bottom. A pump 16 is fixedly provided at the top of the sedimentation shell 18. A discharge pipe 17 is fixedly connected to the output end of the pump 16. An absorption pipe 12 is connected to the input end of the pump 16. The absorption pipe 12 extends into the inner tube 24. The absorption pipe 12 and the inner tube 24 are slidably connected in the axial direction. In this embodiment, the absorption pipe 12 and the inner tube 24 are connected by a keyway structure. The absorption pipe 12 can only move up and down inside the inner tube 24. The absorption pipe 12 and the inner tube 24 are interlocked, so that the inner tube 24 cannot rotate outside the absorption pipe 12.A feed pipe 33 is fixedly installed at the top of the sedimentation shell 18. Flocculant is injected into the sedimentation shell 18 through the feed pipe 33. After the wastewater inside the sedimentation shell 18 reaches a certain amount, flocculant is injected into the sedimentation shell 18 through the feed pipe 33. The first motor 14 is started, which controls the transmission shaft 25 to rotate. The transmission shaft 25 drives the second gear 26 to rotate, which in turn drives the first gear 15 to rotate. The first gear 15 drives the square shell 11 to rotate, which in turn drives the smoothing blade 34 to rotate. The second motor 22 is started, which controls the lead screw 9 to rotate. The lead screw 9 drives the sliding plate 10 to rise and fall. The 0-axis drives the square shell 11 and the smoothing blade 34 to rise and fall, making it easier for the smoothing blade 34 to penetrate deep into the wastewater. The rotation of the smoothing blade 34 accelerates the full fusion of wastewater and flocculant, thereby causing impurities in the wastewater to form flocs. Under the action of gravity, they are separated from the aqueous phase and precipitated. After complete fusion, the pump 16 is started. The pump 16 draws in the treated water through the absorption pipe 12 and discharges it through the discharge pipe 17. The filter plate 32 intercepts the flocs, and the rotating scraper 35 cleans the surface of the filter plate 32 to prevent the filter plate 32 from clogging. The water inside the sedimentation shell 18 decreases, and the smoothing blade 34 rotates and continues to rotate to smooth and flatten the flocs that are pressed down and settled, until all of them settle on the surface of the support plate 28.

[0039] In order to achieve the purpose of feeding, the device adopts the following technical solution: the top of the filter housing 1 is fixedly provided with a feeding housing 2, and the feeding housing 2 facilitates the discharge of wastewater;

[0040] To achieve the purpose of support, the device adopts the following technical solution: multiple support rods 6 are fixedly provided between the filter housing 1 and the sedimentation housing 18, and the support rods 6 support and fix the filter housing 1 and the sedimentation housing 18.

[0041] To achieve the processing objective, this device employs the following technical solution: Each sidewall of the sedimentation shell 18 is provided with a sliding rod groove 31, and each of the two sliding rod grooves 31 contains a sliding rod 30 extending out of the sliding rod groove 31. A support ring 20 is fixedly installed at the bottom of each of the two sliding rods 30. A bearing plate 28 is rotatably connected inside the support ring 20. The bearing plate 28 is threadedly connected to the inner wall of the sedimentation shell 18. A handle 29 is fixedly installed at the bottom of the bearing plate 28. By rotating the handle 29, the handle 29 drives the bearing plate 28 to rotate. The bearing plate 28 is detachable, facilitating the cleaning of the precipitated flocs.

[0042] The support ring 20 plays a crucial supporting role in the device. Since the support plate 28 needs to be able to support the settled flocs and can be easily disassembled and cleaned when needed, a stable support structure is required. The support ring 20 is such a structure; it is fixedly connected to the bottom of the slide bar 30, providing a reliable support surface for the support plate 28.

[0043] The slide bar 30 serves as a connector and guide in the device. One end is fixedly connected to the support ring 20, while the other end extends out of the slide bar groove 31 and connects to the external structure of the sedimentation shell 18. The presence of the slide bar 30 allows the support plate 28 to rotate and be disassembled along a certain trajectory. At the same time, the slide bar 30 also has a certain rigidity to resist the weight of the support plate 28 and the sediment on it, ensuring the stability and safety of the entire structure.

[0044] The slide bar groove 31 is a slot on the sedimentation shell 18 designed to accommodate the slide bar 30. Its shape and size match the slide bar 30, ensuring that the slide bar 30 can slide smoothly within it. The presence of the slide bar groove 31 not only provides guidance and support for the slide bar 30, but also limits the rotation range of the slide bar 30 and the support plate 28.

[0045] To achieve the purpose of support, the device adopts the following technical solution: both sides of the sedimentation shell 18 are fixedly provided with fixing plates 19, and the bottom of the two fixing plates 19 are fixedly provided with support plates 21. The sedimentation shell 18 is supported by the cooperation of the fixing plates 19 and the support plates 21.

[0046] The usage process of this utility model is as follows: When using this utility model, chemical wastewater is injected into the filter housing 1 through the feed housing 2. The wastewater falls into the filter cylinder 36, where the solid particles in the wastewater are filtered. During the filtration process, the third motor 48 is started, which controls the connecting plate 49 to rotate. The connecting plate 49 drives the sliding column 50 to rotate, and the sliding column 50 slides within the slide rail frame 51, pushing the slide rail frame 51 to reciprocate. The slide rail frame 51 reciprocates, pushing the toothed plate 55 to reciprocate. The toothed plate 55 drives the fifth gear 52 to rotate clockwise by a certain angle and then counterclockwise, causing the fifth gear 52 to drive the connecting rod 39 to rotate. The connecting rod 39 then drives the third gear 40 to rotate. The third gear 40 drives the fourth gear 43 to rotate, which in turn drives the rotating sleeve 42 to rotate. The rotating sleeve 42 drives the connecting strip 44 and the push plate 45 to perform a pendulum motion. When two of the push plates 45 swing counterclockwise, the other two push plates 45 swing clockwise. The push plates 45 push the wastewater in the filter cylinder 36, allowing the wastewater to pass through the through groove 46, thus accelerating the filtration process. At the same time, the push plates 45 push the solid particles in the wastewater out of the filter cylinder 36. The solid particles fall into the slag discharge plate 37, ensuring that the filter cylinder 36 continues to filter and improving its service life. The solid particles slide on the slag discharge plate 37 and pass through the slag discharge port 4, falling into the slag discharge shell 5 and being discharged through the opening at the bottom of the slag discharge shell 5. A conveyor belt can be installed at the bottom of the slag discharge shell 5 for conveying. The filtered wastewater enters the sedimentation shell 18 through the feed pipe 3 and the transfer pipe 7. After the wastewater inside the sedimentation shell 18 reaches a certain amount, flocculant is injected into the sedimentation shell 18 through the feed pipe 33. The first motor 14 is started, which controls the drive shaft 25 to rotate. The drive shaft 25 drives the second gear 26 to rotate, which in turn drives the first gear 15 to rotate. The first gear 15 drives the square shell 11 to rotate, which in turn drives the smoothing blade 34 to rotate. The second motor 22 is started, which controls the lead screw 9 to rotate. The lead screw 9 drives the sliding plate 10 to rise and fall. The sliding plate 10 drives the square shell 11 and the smoothing blade 34 to rise and fall, facilitating smoothing. The flat blade 34 penetrates deep into the wastewater, and its rotation accelerates the full fusion of the wastewater and flocculant, causing impurities in the wastewater to form flocs. Under gravity, these flocs detach from the aqueous phase and settle. Once fully fused, the pump 16 is activated, drawing in the treated water through the absorption pipe 12 and discharging it through the discharge pipe 17. The filter plate 32 intercepts the flocs, and the rotating scraper 35 cleans the surface of the filter plate 32 to prevent clogging. As the water level inside the sedimentation shell 18 decreases, the flat blade 34 rotates and continues to flatten and press down the settled flocs until they are all settled on the surface of the support plate 28. The handle 29 is then rotated, causing the support plate 28 to rotate. The support plate 28 is detachable for easy cleaning of the settled flocs.

Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
