Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and more specifically to a flocculation device for wastewater treatment. Background Technology
[0002] In wastewater treatment, flocculation is crucial. By adding flocculants, suspended particles in wastewater are formed into flocs, which are then purified through sedimentation and filtration. The performance of the flocculation device affects the treatment efficiency and the achievement of water quality standards.
[0003] When performing flocculation, the addition of flocculant is a critical step. Flocculants are usually added either in advance or during mixing. In advance, the flocculant is added all at once before the wastewater is poured in. This makes it difficult for the flocculant to react quickly and fully with the wastewater when it is poured in later, which affects the flocculation efficiency and effect. In the mixing part, the flocculant is added continuously. New flocculants are added before the flocculant has fully reacted, which can easily lead to poor reaction effect, low floc quality, or excessive flocculant content, resulting in waste, increased costs, and possible secondary pollution. To address these issues, we propose a flocculation device for wastewater treatment. Utility Model Content

[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. In this utility model, when the driving gear rotates, it drives the driven gear to rotate, causing the squeezing plate at the bottom of the driven gear to contact and squeeze the driven plate at the bottom of the reagent tank at intervals. This causes the driven plate to move the closing plate inside the movable groove through the auxiliary strip and connecting rod, thereby opening the discharge slot through the movement of the closing plate, allowing the reagent inside the reagent tank to be effectively discharged. At the same time, when the squeezing plate separates from the driven plate, the closing plate returns through the auxiliary spring, causing the closing plate to seal the discharge slot again. This allows for the effective intermittent addition of reagent during the stirring operation, resulting in a more uniform flocculation process and greatly optimizing the flocculation effect.
[0015] 2. In this utility model, the guide trough plate can effectively conduct the agent discharged from the agent tank as far as possible towards the stirring center, thereby facilitating the mixing of the agent and water source during the stirring operation. At the same time, through the guide ring plate on the drive shaft, the discharged agent, after contacting the guide ring plate, can better assist the diffusion of the agent during the stirring operation due to the inertia generated by rotation and the inclined arc surface of the guide ring plate, thereby effectively improving the flocculation reaction when mixing flocculants in wastewater treatment operations.

[0026] Furthermore, a guide trough 5 is inclinedly provided at the bottom of the medicine box 6, and the top of the guide trough 5 corresponds to the position of the medicine discharge trough hole 10.
[0027] Furthermore, a guide ring plate 4 is provided on the drive shaft 3. The guide ring plate 4 is a downwardly inclined annular plate, and the bottom end of the guide groove plate 5 and the position of the guide ring plate 4 correspond to each other.
[0028] In this embodiment, the guide trough 5 can effectively conduct the agent discharged from the agent tank 6 to the mixing center as much as possible, thereby facilitating the mixing of the agent and water during the mixing operation.
[0029] In this embodiment, the guide ring plate 4 on the drive shaft 3 enables the discharged agent to diffuse better during the stirring operation by means of the inertia generated by the rotation and the inclined arc surface on the guide ring plate 4 after contacting it.
[0030] Furthermore, a drive assembly is provided at the bottom of the medicine box 6.
[0031] Furthermore, the bottom of the medicine box 6 is equipped with an adjustment component that is intermittently activated by a drive component.
[0032] Furthermore, a sealing component is installed on the medicine tank 6 at the position corresponding to the medicine discharge slot 10, which allows for intermittent medicine discharge through an adjustment component.
[0033] Furthermore, the drive assembly includes a drive gear 7, a driven gear 8, a pressing plate 9, a retaining ring 20, a movable sleeve 21, and a fixed shaft 22. The drive gear 7 is fixedly mounted on the drive shaft 3, and the driven gear 8 is located at the bottom of the medicine tank 6. The driven gear 8 and the drive gear 7 mesh with each other. The specifications and number of teeth of the driven gear 8 are greater than those of the drive gear 7. The specifications and number of teeth of the driven gear 8 are at least twice those of the drive gear 7. The ratio of the specifications and number of teeth of the driven gear 8 to those of the drive gear 7 is adjusted according to actual needs and the dosage ratio.
[0034] In this embodiment, the difference in specifications and number of teeth between the driven gear 8 and the driving gear 7 enables the driving gear 7 to drive the driven gear 8 to rotate slowly when it rotates.
[0035] Furthermore, the fixed shaft 22 is fixedly installed at the bottom of the medicine box 6, the movable sleeve 21 is movably installed on the fixed shaft 22, and the driven gear 8 is fixedly installed on the movable sleeve 21. Driven by the driving gear 7, the driven gear 8 can drive the movable sleeve 21 to rotate on the fixed shaft 22. The fixed ring 20 is located at the bottom of the driven gear 8, and the fixed ring 20 and the movable sleeve 21 are fixedly connected to each other. A pressing plate 9 that can trigger the adjustment component is fixedly installed on the side wall of the fixed ring 20. The end of the pressing plate 9 away from the fixed ring 20 is arc-shaped.
[0036] In this embodiment, the squeezing plate 9 at the bottom of the driven gear 8 enables the driving gear 7 to intermittently trigger the adjusting component after driving the driven gear 8 to rotate, so that the blocking component can be effectively opened intermittently to discharge the medicine.
[0037] Furthermore, the sealing assembly includes a closing plate 11, a movable groove 12, an auxiliary spring 13, and a barrier plate 14. The movable groove 12 is located on the side of the medicine tank 6 corresponding to the discharge slot 10 away from the driven gear 8, and the movable groove 12 and the discharge slot 10 are internally connected. The barrier plate 14 is located on the inner side of the movable groove 12 near the discharge slot 10, and the height of the barrier plate 14 is adapted to the depth of the movable groove 12. The closing plate 11 is located at the bottom of the discharge slot 10, and the closing plate 11 and the barrier plate 14 are fixedly connected to each other. An auxiliary spring 13 is fixedly installed at intervals on the side of the barrier plate 14 away from the closing plate 11, and the end of the auxiliary spring 13 away from the barrier plate 14 is fixedly installed on the inner wall of the movable groove 12 at the corresponding position.
[0038] In this embodiment, the auxiliary spring 13 inside the movable groove 12 enables the sealing component to be reset after the adjustment component interval is triggered to open.
[0039] Furthermore, the adjustment assembly includes an adjustment groove 15, an auxiliary strip 16, a connecting rod 17, a driven plate 18, and a fixing rod 19. The adjustment groove 15 is located on the medicine tank 6 at a position corresponding to the discharge slot 10 near the driven gear 8, and the interior of the baffle plate 14 and the discharge slot 10 are interconnected. The auxiliary strip 16 is located on the inner side of the adjustment groove 15 at a position away from the discharge slot 10. The connecting rod 17 is fixedly installed at intervals on the side of the auxiliary strip 16 near the closing plate 11. The end of the connecting rod 17 away from the auxiliary strip 16 is fixedly connected to the closing plate 11. The driven plate 18 is located at the bottom of the auxiliary strip 16 at a position corresponding to the squeezing plate 9. The fixing rod 19 is fixedly installed on the side of the driven plate 18 near the auxiliary strip 16. The end of the fixing rod 19 away from the driven plate 18 is fixedly connected to the auxiliary strip 16. The side of the driven plate 18 near the driven gear 8 is arc-shaped.
[0040] In this embodiment, the arc-shaped extrusion plate 9 and driven plate 18 make it easier for the extrusion plate 9 and driven plate 18 to come into contact and extrude, so that the driven plate 18 can smoothly drive the closing plate 11 to move through the auxiliary strip 16 and connecting rod 17, thereby causing the medicine discharge slot 10 to open intermittently.
[0041] In this embodiment, the connecting rods 17 are arranged at intervals, so that the agent can be discharged effectively and without obstruction after the closing plate 11 is opened.
[0042] Furthermore, the inside of the medicine tank 6 is provided with a guide slope to facilitate the conduction of medicine at the position corresponding to the medicine discharge slot 10.
[0043] Furthermore, sliders are installed at both ends of the closing plate 11 and the auxiliary strip 16, and the inner sides of the discharge slot 10, the movable slot 12 and the adjustment slot 15 are provided with sliding grooves to facilitate the movement of the sliders on the closing plate 11 and the auxiliary strip 16.
[0044] The working principle and usage process of this utility model are as follows: When in use, the wastewater to be treated is transferred to the inside of the flocculation tank 1 through the liquid inlet pipe. The drive shaft 3 is driven by the drive device 2 to stir the wastewater inside the flocculation tank 1. At the same time, the reagent is transferred to the inside of the flocculation tank 1 through the reagent tank 6 at intervals, so that the reagent and the wastewater inside the flocculation tank 1 are mixed and flocculated. The treated liquid is transferred to the designated location through the liquid outlet pipe, thereby completing the operation.
[0045] When the driving gear 7 rotates, it drives the driven gear 8 to rotate, causing the squeezing plate 9 at the bottom of the driven gear 8 to intermittently contact and squeeze the driven plate 18 at the bottom of the reagent tank 6. This causes the driven plate 18 to move the closing plate 11 inside the movable groove 12 via the auxiliary strip 16 and connecting rod 17. As a result, the discharge hole 10 is opened by the movement of the closing plate 11, allowing the reagent inside the reagent tank 6 to be effectively discharged. At the same time, when the squeezing plate 9 disengages from the driven plate 18, the closing plate 11 returns to its original position via the auxiliary spring 13, causing the closing plate 11 to seal the discharge hole 10 again. This allows for the intermittent addition of reagent during the mixing operation, resulting in a more uniform flocculation process and greatly optimizing the flocculation effect.
[0046] The guide trough 5 effectively guides the agent discharged from the agent tank 6 towards the mixing center, facilitating mixing of the agent and water during the mixing process. Simultaneously, the guide ring 4 on the drive shaft 3 allows the discharged agent to diffuse better during the mixing process due to the inertia generated by rotation and the inclined arc surface of the guide ring 4, thereby effectively improving the flocculation reaction during flocculant mixing in wastewater treatment operations.
[0047] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
