Detailed Implementation

[0018] The following is in conjunction with the appendix Figure 1-9 The present invention will be further described in detail below: This utility model discloses a device for wastewater treatment using a non-powered spiral hydraulic impact mixer, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, it includes: equipment housing 1, partition plate 33, flow channel plate 16, and pressure diversion mechanism.

[0019] The equipment casing 1 has an inlet 26. A partition plate 33 is fixedly connected inside the equipment casing 1. A flow channel plate 16 is fixedly connected to the bottom of the partition plate 33. The partition plate 33 and the flow channel plate 16 together form a spiral flow channel 42. The inlet 26 is connected to the spiral flow channel 42, so that the wastewater moves in a spiral motion along the spiral flow channel 42. The downward pressure diversion mechanism is fixedly connected to the side wall of the partition plate 33 and includes an adjustment component, a transmission component and a diversion component. The adjustment component is connected to the diversion component through the transmission component, so that the diversion component performs hydraulic impact premixing on the wastewater entering the spiral flow channel 42 under the action of the adjustment component.

[0020] In this embodiment, by adding a downward pressure diversion mechanism, the adjustment component, under the action of the transmission component, adjusts the diversion component to a suitable position. This allows the wastewater to be treated, added through the inlet 26, and the wastewater entering from the spiral channel 42 to collide and flow around the diversion baffle 14 under the action of the diversion baffle 14, significantly increasing the turbulence of the water flow. This turbulence significantly enhances the diffusion and eddy diffusion between the mixed wastewater and the reagent, providing favorable conditions for thorough mixing. Consequently, a strong eddy is formed in the spiral channel 42, promoting thorough mixing of the wastewater and the reagent, and further ensuring uniform stirring and overall mixing efficiency.

[0021] like Figure 1 , Figure 2 As shown, the adjustment assembly includes: a sliding protrusion 12, a push plate 19, a locking groove 20, a locking rod 21, a locking spring 23, and an adjustment rod 25.

[0022] The equipment housing 1 has a downward driving cavity 10 inside, which is located on the upper side of the partition plate 33. The equipment housing 1 has a spring groove 22, and the side wall of the locking groove 20 has an adjustment hole 24. The push plate 19 is slidably connected to the side wall of the equipment housing 1 and slides through the equipment housing 1. The push plate 19 has several locking grooves 20. The locking rod 21 is slidably connected in the spring groove 22 and engages with the locking groove 20. The locking spring 23 is set in the spring groove 22. One end of the locking spring 23 is fixedly connected to the side wall of the spring groove 22, and the other end of the locking spring 23 is fixedly connected to the side wall of the locking rod 21. The adjustment rod 25 is fixedly connected to the side wall of the locking rod 21 and passes through the adjustment hole 24. The adjustment rod 25 slides with the adjustment hole 24.

[0023] In this embodiment, by adding an adjusting rod 25, the adjusting rod 25 causes the locking rod 21 to slide within the spring groove 22 and lock the spring 23, thereby separating the locking rod 21 from the locking groove 20 of the push plate 19. When the push plate 19 slides to the appropriate position, the locking rod 21 is then inserted into the corresponding locking groove 20. This achieves flexible adjustment and precise fixation of the position of the push plate 19. When the position of the push plate 19 needs to be adjusted, the adjusting rod 25 is released, and the locking rod 21 will automatically reset under the action of the locking spring 23 and re-engage with the locking groove 20, thereby firmly fixing the push plate 19 in the current position.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 5 As shown, the diversion assembly includes: a lower pressure plate 13, a diversion baffle 14, and a flow channel outlet pipe 34.

[0025] The partition plate 33 has a baffle through hole 15, the flow channel plate 16 has a flow channel outlet 17 on its side wall, the diversion baffle 14 is slidably connected to the side wall of the baffle through hole 15, the lower pressure plate 13 is fixedly connected to the top of the diversion baffle 14, the lower pressure plate 13 is set inside the lower pressure drive cavity 10, the flow channel outlet pipe 34 is fixedly connected to the bottom of the flow channel plate 16, and the flow channel outlet pipe 34 is connected to the flow channel outlet 17.

[0026] In this embodiment, by adding a lower pressure plate 13, the driving component causes the lower pressure plate 13 to slide downwards, and the diversion baffle 14 slides from the baffle through hole 15 into the spiral flow channel 42. The lower pressure plate 13 is subjected to the force of the driving component in the lower pressure driving cavity 10, which stably drives the diversion baffle 14 to slide up and down, ensuring the smoothness and reliability of the entire diversion process.

[0027] like Figure 3 , Figure 5 , Figure 8 As shown, the transmission assembly includes: a connecting bottom block 28, a connecting top block 29, a first cross rod 30, a second cross rod 31, and a roller 32.

[0028] The transmission components are arranged on both sides of the push plate 19. The connecting bottom block 28 is fixedly connected to the side wall of the lower pressure plate 13, and the connecting top block 29 is fixedly connected to the top wall of the lower pressure drive cavity 10. One end of the first cross rod 30 is rotatably connected to the side wall of the connecting bottom block 28, and the other end of the first cross rod 30 is fixedly connected to the side wall of the push plate 19. One end of the second cross rod 31 is rotatably connected to the side wall of the connecting top block 29, and the other end of the first cross rod 30 is rotatably connected to the roller 32. The roller 32 is in rolling engagement with the lower pressure plate 13, and the midpoint of the first cross rod 30 is in rotating engagement with the midpoint of the second cross rod 31.

[0029] In this embodiment, by adding the first cross rod 30 and the second cross rod 31, the sliding push plate 19 can drive the first cross rod 30 and the second cross rod 31 on the push plate 19, thereby causing the lower pressure plate 13 to drive the diversion baffle 14 to slide downward, and causing the diversion baffle 14 to slide from the baffle through hole 15 into the spiral flow channel 42. This allows the wastewater to be treated, added through the inlet 26, and the wastewater entering from the spiral flow channel 42 to collide with the diversion baffle 14 under the action of the diversion baffle 14. The flow around the water significantly increases the turbulence of the water flow. This turbulence causes diffusion and eddy diffusion between the mixed wastewater and the reagent, and premixing before the reaction. Due to the linkage between the first cross rod 30 and the second cross rod 31, the downward pressing process of the lower plate 13 is smooth and controllable, ensuring that the diversion baffle 14 can accurately slide to the designated position, thereby effectively guiding the wastewater and reagent into the spiral flow channel 42 for premixing. This design not only improves the efficiency of wastewater treatment, but also lays a good foundation for subsequent fusion treatment.

[0030] like Figure 3 As shown, a sliding groove 41 is provided on the top wall of the pressure drive cavity 10, and a sliding protrusion 12 is provided on the top of the push plate 19. The sliding groove 41 and the sliding protrusion 12 are slidably engaged.

[0031] In this embodiment, by adding a sliding groove 41 and a sliding protrusion 12 for sliding engagement, the push plate 19 slides, and the sliding protrusion 12 slides within the sliding groove 41, effectively achieving guidance and limitation. This guidance and limitation method ensures the stability of the push plate 19 during movement and avoids the push plate 19 from deviating or shaking during sliding, thereby improving stability.

[0032] like Figure 4 As shown, the diversion baffles 14 and baffle through holes 15 are spirally staggered along the flow channel plate 16. There are N diversion baffles 14 and baffle through holes 15, where N≥2, to extend the wastewater mixing path.

[0033] In this embodiment, by increasing the number of diversion baffles 14 and baffle through holes 15, the flow path of wastewater in the flow channel plate 16 is significantly extended, thereby increasing the residence time of wastewater in the device. At the same time, the spiral staggered distribution also helps to enhance the turbulence of wastewater and promote the pre-fusion between wastewater and reagent.

[0034] like Figure 1 , Figure 2 As shown, it also includes a stirring mechanism disposed inside the equipment housing 1, including a stirring and scraping assembly and an auxiliary bottom stirring assembly.

[0035] like Figure 1 , Figure 2 , Figure 3 As shown, the mixing and scraping assembly includes: a motor 2, a reducer 3, a support frame 4, a support base 5, a mixing rod 6, a top mixing blade 7, a cleaning rod 8, a cleaning scraper 9, and a water outlet 40; the equipment casing 1 has a water outlet 40. The support base 5 is fixedly connected to the top of the equipment shell 1, the support frame 4 is fixedly connected to the top of the support base 5, the reducer 3 is fixedly connected to the top of the support frame 4, the motor 2 is fixedly connected to the side wall of the support frame 4, the output end of the motor 2 cooperates with the reducer 3, the stirring rod 6 is fixedly connected to the output end of the motor 2; the stirring rod 6 passes through the side wall of the equipment shell 1 and enters the interior of the equipment shell 1, the top stirring blade 7 is fixedly connected to the side wall of the stirring rod 6, the cleaning rod 8 is fixedly connected to the two side walls of the stirring rod 6, and the cleaning scrapers 9 are fixedly connected to the ends of the two cleaning rods 8 respectively.

[0036] In this embodiment, by adding a motor 2, the output end of the motor 2 is adjusted to a suitable speed under the action of the reducer 3, and then the output end drives the stirring rod to drive the top stirring blade 7 for stirring. At the same time, the cleaning scraper 9, driven by the stirring rod 6, scrapes along the inner wall of the equipment shell 1, effectively preventing the material from adhering and accumulating on the inner wall of the equipment. Moreover, the setting of the cleaning rod 8 and the cleaning scraper 9 can also enhance the stirring effect to a certain extent, making the material more thoroughly stirred.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 9 As shown, the auxiliary bottom stirring assembly includes: a transmission chamber 11, an auxiliary stirring rod 35, a first gear 36, an auxiliary stirring blade 37, a bottom stirring blade 38, and a second gear 39.

[0038] The transmission chamber 11 is fixedly connected to the bottom wall of the equipment housing 1. The transmission chamber 11 has a transmission cavity 18. The stirring rod 6 passes through the transmission chamber 11, and the end of the stirring rod 6 is located inside the transmission cavity 18. The second gear 39 is fixedly connected to the end of the stirring rod 6. The bottom stirring blade 38 is fixedly connected to the side wall of the stirring rod 6. The auxiliary stirring rod 35 is rotatably connected to the side wall of the transmission chamber 11. The auxiliary stirring rod 35 passes through the side wall of the transmission chamber 11 and rotatably engages with the through transmission chamber 11. The first gear 36 is fixedly connected to the end of the auxiliary stirring rod 35 located in the transmission cavity 18. The first gear 36 meshes with the second gear 39. The auxiliary stirring blade 37 is fixedly connected to the end of the auxiliary stirring rod 35 located outside the transmission cavity 18.

[0039] In this embodiment, by adding a second gear 39, the stirring rod 6 drives the bottom stirring blade 38, which in turn drives the second gear 39 at the bottom to rotate. This causes several first gears 36 meshing with the second gear 39 to drive the auxiliary stirring rod 35 to rotate, and the auxiliary stirring blade 37 to stir. This makes the stirring inside the bottom wall of the equipment shell 1 more uniform. This design not only enhances the stirring effect, but also effectively prevents the formation of stirring dead corners inside the bottom wall of the equipment shell 1, ensuring that the materials are fully and uniformly mixed, thus making the overall stirring process more efficient and reliable.

[0040] like Figure 9 As shown, the auxiliary stirring rod 35, the first gear 36, and the auxiliary stirring blade 37 are arranged in an array along the center of the second gear 39. The number of auxiliary stirring rods 35, the first gear 36, and the auxiliary stirring blade 37 is M, where M≥2.

[0041] In this embodiment, by increasing the number of auxiliary stirring rods 35, first gears 36, and auxiliary stirring blades 37, the reagent at the bottom of the equipment housing 1 is more fully mixed with the wastewater. This design effectively improves the stirring efficiency, ensures the uniform distribution of the reagent in the wastewater, and avoids dead corners during the stirring process, making the entire treatment process more efficient and stable.

[0042] The implementation principle of this utility model embodiment is as follows: First, the operator slides the adjusting rod 25, causing the locking rod 21 to slide in the spring groove 22 and lock the spring 23, thereby separating the locking rod 21 from the locking groove 20 of the push plate 19. When the push plate 19 slides to the appropriate position, the locking rod 21 is then inserted into the corresponding locking groove 20. Next, the push plate 19 is slid, so that the sliding protrusion 12 slides in the sliding groove 41, and drives the first cross rod 30 and the second cross rod 31 on the push plate 19. This causes the lower pressure plate 13 to drive the diversion baffle 14 to slide downward, and the diversion baffle 14 slides from the baffle through hole 15 into the spiral flow channel 42. Then, the wastewater to be treated added through the inlet 26 and the wastewater entering from the spiral flow channel 42 are subjected to the action of the diversion baffle 14, and the wastewater collides and flows around the diversion baffle 14, which greatly increases the turbulence of the water flow. This turbulence makes the diffusion and eddy diffusion between the mixed wastewater and the agent significantly enhanced, providing the driving conditions for full mixing. Next, the premixed wastewater and reagents flow from the spiral channel 42 into the channel outlet 17, and then from the channel outlet pipe 34 into the equipment shell 1. Then, the motor 2 is started, and the output end of the motor 2 is adjusted to a suitable speed under the action of the reducer 3. Then, the output end drives the stirring rod 6 to drive the top stirring blade 7 to stir. At the same time, the stirring rod 6 drives the bottom stirring blade 38 and drives the bottom second gear 39 to rotate, so that several first gears 36 meshing with it drive the auxiliary stirring rod 35 to rotate and drive the auxiliary stirring blade 37 to stir, thereby making the bottom wall inside the equipment shell 1 more uniformly stirred. Finally, the cleaning rods 8 on both sides of the stirring rod 6 drive the cleaning scraper 9 to clean the inner wall of the equipment shell 1, and the wastewater with fully mixed reagent is discharged from the outlet 40.
