[0007] By adopting the above technical scheme, before treating and purifying wastewater, a purification solid block such as activated carbon or polyaluminium chloride is placed in the placement slot of the placement block. When the purified wastewater needs to be treated, the water inlet valve is opened to add the wastewater into the treatment tank through the water inlet pipe, the drive member is started to drive the stirring rod to rotate to stir the wastewater, and the purification solid block placed in the placement slot is ground by the grinding component, so that the granular purification powder formed after grinding enters the treatment tank from the feeding trough and contacts with the wastewater, and the wastewater is naturally purified under the stirring of the stirring rod. After a certain period of purification, the drain valve is opened to discharge the purified wastewater and the purification powder from the treatment tank through the drain pipe, thereby completing the purification of the wastewater, and then the wastewater can continue to be added through the water inlet pipe for treatment. By setting a grinding device, the purified powder is ground as needed for purification, so that after each purification is completed, no additional purification powder needs to be added, and the wastewater can be directly added for continuous treatment, thereby improving the convenience of purification.

When the driving member drives the grinding block to rotate through the transmission component, the grinding tooth blocks on the grinding block rub and cut the purification solid block, and at the same time, the grinding tooth blocks on the bottom wall of the placement groove rub and cut the purification solid block together, thereby continuously grinding out powder from the purification solid block, so that the purified powder can be stored in the treatment tank in the form of purified solid blocks, and in the process of purification and stirring, the grinding component is driven to work through the transmission component to grind into powder and put into the treatment process, thereby simplifying the process of grinding and powder feeding, thereby realizing continuous treatment and purification of wastewater, and there is no need to grind and feed powder before each batch of purification, thereby improving the convenience of wastewater purification treatment, that is, improving the convenience of using the wastewater treatment purification equipment.

[0013] By adopting the above technical solution, when the driving member drives the stirring rod to rotate, the driving member will drive the first gear to rotate, and through the engagement with the second gear, drive the second gear to rotate, thereby driving the grinding block in the grinding groove to rotate, so that the grinding teeth on the grinding block rub and cut the purification fixed body, thereby performing powder grinding. The operation is simple and convenient. The grinding block is driven to rotate for grinding by the driving member and the transmission assembly, and there is no need to set up a new driving member for driving.

[0015] By adopting the above technical solution, the bottom wall of the stirring rod can be made of a material with less friction, thereby reducing the rotational friction resistance caused by the abutment with the drain pipe. The first gear and the stirring rod are driven up and down by the lifting member, so that the stirring rod can abut against the drain pipe, thereby blocking the drain pipe, so that the ground powder will not enter the drainage pipe, reducing the possibility of purified powder being mixed in the purified liquid. After stirring and sedimentation, the purified powder is precipitated in the sedimentation tank. After lifting the first gear and the stirring rod by the lifting assembly, the drain valve is opened, and the purified liquid can be discharged from the drain pipe. The stirring rod is used to block the drain pipe to further improve the cleanliness of the purification.

At this time, the drain valve can be opened to drain the water. At the same time, the lifting cylinder will drive the lifting rod to rise in the lifting groove through the second lifting rod, thereby driving the grinding block to rise, so that the grinding block will not perform the grinding operation at this time, reducing the possibility of powder generated during drainage mixing into the purified and precipitated water, and further improving the degree of water purification.

[0025] By adopting the above technical solution, the placement block is arranged near the water outlet of the water inlet pipe. When the water inlet valve is opened to add the purified liquid into the treatment tank, the liquid will rush through the placement block, thereby flushing the ground powder retained in the feeding trough of the placement block into the treatment tank for stirring, thereby reducing the possibility of purified powder being retained in the feeding trough and improving the convenience of purification treatment.

It is not necessary to open the treatment tank 1 and add purification powder before each batch of wastewater treatment, thereby improving the convenience of use.

[0034] To further improve the convenience of use, refer to Figures 2 to 4 The grinding assembly 3 includes a cylindrical grinding block 31 and a grinding tooth block 32. The grinding tooth block 32 is integrally arranged on the grinding block 31 and the bottom wall of the placement groove 151. A positioning column 21 is fixedly arranged on the bottom wall of the processing chamber 11. A cylindrical positioning block 2 is fixedly arranged on the positioning column 21. A circular grinding groove 22 is arranged on the bottom wall of the positioning block 2. The grinding block 31 is rotatably arranged in the grinding groove 22 and can slide in the grinding groove 22. The grinding block 31 passes through the replacement groove 112 and is inserted into the placement groove 151. A connecting spring 34 is fixedly arranged on the inner wall of the grinding groove 22. A moving block is adapted to slide in the grinding groove 22. The moving block is rotatably connected to the grinding block 31 through a rotating shaft. The grinding tooth block 32 is arranged on the bottom wall away from the grinding block 31 and away from the moving block. A transmission assembly 5 for driving the grinding block 31 to rotate is arranged between the grinding block 31 and the driving motor 4. When the driving motor 4 is started, the driving motor 4 drives the stirring rod 14 to stir, and at the same time drives the grinding block 31 to rotate through the transmission component 5. The rotation of the grinding block 31 causes the grinding tooth block 32 to cut and grind the purified solid block placed in the placement groove 151, and the ground powder enters the treatment tank 1 through the feeding groove 152 and is mixed with the wastewater. In this process, the water inlet pipe 12 is close to the placement groove 151, and the powder retained in the feeding groove 152 can be flushed into the treatment tank 1 when water is taken in, thereby further improving the convenience of use.

[0035] In order to save energy and reduce consumption, refer to Figure 2 and Figure 3The transmission assembly 5 includes a first gear 51 and a second gear 52. The first gear 51 is rotatably arranged in the processing chamber 11 and is fixedly connected to the top wall of the stirring rod 14. The second gear 52 is fixedly arranged on the outer wall of the grinding block 31 and meshes with the second gear 52. The first gear 51 is penetrated by a square first auxiliary groove 511. The top of the stirring rod 14 is provided with a square second auxiliary groove 142 which is communicated with the first auxiliary groove 511. A square auxiliary sleeve 41 is fixedly arranged on the rotating shaft of the driving motor 4 by bolts. The auxiliary sleeve 41 is adapted to pass through the first auxiliary groove 511 and is adapted to be inserted into the second auxiliary groove 142. When the driving motor 4 is started, the driving motor 4 drives the first gear 51 and the stirring rod 14 to rotate through the auxiliary sleeve 41. The rotation of the first gear 51 drives the second gear 52 to rotate. The rotation of the second gear 52 drives the grinding block 31 to rotate in the placement groove 151 for grinding. The driving motor 4 provides power to save energy and reduce consumption.

[0036] In order to improve the cleanliness of wastewater purification, refer to Figure 2 and Figure 3 The inner bottom wall of the treatment tank 1 is provided with a circle of sedimentation tanks 162 around the drain pipe 13. The sedimentation tank 162 covers the inner bottom wall of the treatment tank 1. The inner wall of the sedimentation tank 162 is inclined. The bottom wall of the sedimentation tank 162 is provided with a sedimentation pipe 16 that communicates with the outer wall of the treatment tank 1. The sedimentation pipe 16 is provided with a sedimentation valve 161. The stirred wastewater is left to stand for a period of time so that the powder in the water is precipitated in the sedimentation tank 162. At this time, the drain valve 131 can be opened to discharge the purified wastewater through the drain valve 131. Only the sedimentation valve 161 will be opened to discharge the water containing powder from the sedimentation pipe 16, thereby reducing the possibility that the purified water contains powder and improving the cleanliness of the wastewater purification.

[0037] In order to further improve the cleanliness of purification, refer to Figures 2 to 4 The top wall of the processing chamber 11 is fixedly provided with a lifting cylinder 6, and the piston rod of the lifting cylinder 6 is fixedly provided with a circular connecting block 61, and the connecting block 61 is fixedly provided with a T-shaped first lifting rod 62, and the bottom wall of the first lifting rod 62 is provided with a T-shaped block 621, and the block 621 is arranged in an arc shape. A circle of T-shaped slots 512 are arranged on the surface of the first gear 51, and the block 621 is adapted to be inserted into the slot 512 and can move in the slot 512. The end of the stirring rod 14 away from the first gear 51 can abut against the drain pipe 13. The bottom wall of the stirring rod 14 is made of a material with less friction, thereby reducing the rotational friction resistance caused by the abutment with the drain pipe 13, and the stirring rod 14 abuts against the drain pipe 13, thereby reducing the possibility of powder entering the drain pipe 13, and further improving the cleanliness of the purification. When drainage is required, the lifting cylinder 6 is started, and the first gear 51 and the stirring rod 14 are lifted by the first lifting rod 62, so that the bottom of the stirring rod 14 no longer abuts against the drain pipe 13, and the drain valve 131 can be opened for drainage.

[0038] To improve the convenience of replacing the purification solid block, refer to Figures 2 to 4 The connecting block 61 is provided with a T-shaped second lifting rod 63, the outer wall of the positioning block 2 is provided with a lifting groove 23 communicating with the grinding groove 22, and the side wall of the moving block is fixedly provided with a lifting rod 35, which is adapted to pass through the lifting groove 23 and can slide in the lifting groove 23. The first lifting rod 62 and the second lifting rod 63 can be abutted against the lifting rod 35. The outer wall of the processing tank 1 is provided with an opening groove 17 communicating with the processing chamber 11, and the inner wall of the opening groove 17 is only a sliding groove 171, and a sliding block 172 fixedly connected to the second lifting rod 63 is adapted to slide in the sliding groove 171, and the processing chamber 11 is provided with an insertion groove 113 communicating with the sliding groove 171, and the second lifting rod 63 can be inserted into the insertion groove 113. When the purified solid block in the placement slot 151 is ground, the lifting cylinder 6 is started, and the sliding block 172 is driven to slide through the second lifting rod 63, thereby opening the opening slot 17. At the same time, the first lifting rod 62 and the second lifting rod 63 resist and push the lifting rod 35 to slide in the lifting slot 23, thereby driving the rotating block 33 to compress the connecting spring 34, and at the same time driving the grinding block 31 to separate from the placement slot 151. At this time, a new purified solid block can be placed in the placement slot 151 through the opening slot 17 and the replacement slot 112, and the operation is simple and convenient. At the same time, in this embodiment, the first gear 51 and the second gear 52 have the same thickness. When the lifting cylinder 6 drives the first gear 51 to lift through the first lifting rod 62, the first gear 51 may be separated from the second gear 52. The state of the second gear 52 can be adjusted by rotating through the opening slot 17 when the first gear 51 descends, reducing the possibility of the second gear 52 getting stuck with the first gear 51, so that the first gear 51 is still meshed with the second gear 52 after descending. In other embodiments, the thickness of the first gear 51 may be increased so that the first gear 51 continues to be meshed with the second gear 52 after rising.

[0039] The implementation principle of a wastewater treatment and purification device in an embodiment of the present application is as follows: when purifying wastewater, open the water inlet valve 121, discharge the wastewater into the treatment tank 1 through the water inlet pipe 12, and start the drive motor 4 at the same time. The drive motor 4 drives the first gear 51 and the stirring rod 14 to rotate through the auxiliary sleeve 41, and the stirring rod 14 stirs the wastewater. The rotation of the first gear 51 drives the second gear 52 to rotate, and the rotation of the second gear 52 drives the grinding block 31 to rotate in the placement groove 151, so that the grinding tooth block 32 on the grinding block 31 cuts and grinds the purified solid block in the placement groove 151. The purified solid block is composed of activated carbon or polyaluminum chloride. At the same time, the purified solid block is driven to rub and cut with the grinding tooth block 32 on the bottom wall of the placement groove 151, so as to grind out purified powder. The purified powder enters the interior of the treatment tank 1 through the feeding groove 152. At the same time, when the wastewater passes through the water inlet pipe 12, it will rush through the placement block 15 to flush the purified powder retained in the feeding groove 152 into the treatment tank 1. By stirring the wastewater and the purified powder, the purified powder fully absorbs the substances in the wastewater for purification. During this process, the stirring rod 14 abuts against the drain pipe 13 during rotation.

[0040] After stirring for a sufficient time, turn off the drive motor 4, stop stirring and let it stand for a period of time, so that the purified powder is precipitated into the sedimentation tank 162. At this time, start the lifting cylinder 6, lift the first gear 51 and the stirring rod 14 through the first lifting rod 62, so that the bottom of the stirring rod 14 no longer presses against the drain pipe 13, and then open the drain valve 131 to discharge the purified water through the drain pipe 13. Then open the sedimentation valve 161 to discharge the water in the sedimentation tank 162 and the precipitated powder in the sedimentation tank 162 through the sedimentation tank 162. At this time, the lifting cylinder 6 drives the second lifting rod 63 to rise, thereby driving the sliding block 172 to slide and rise, and at the same time, the first lifting rod 62 and the second lifting rod 63 push the lifting rod 35 to rise, thereby driving the grinding block 31 to leave the placement tank 151. At this time, if the purified solid block in the placement tank 151 is ground, use tools such as a climbing vehicle and put a new purified solid block into the placement tank 151 through the inlet tank and the replacement tank 112.

[0041] The wastewater treatment and purification equipment has improved the ability of continuous purification. Compared with the purification equipment in the prior art which needs to open the tank and manually add purification powder after each batch of wastewater is purified, the wastewater treatment and purification equipment is more convenient to use.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
