[0002] In the process of chemical and pharmaceutical production, a large amount of wastewater is generated. Wastewater recycling devices are usually used to treat the wastewater. During the wastewater treatment process, flocculants need to be added to the wastewater to precipitate free ions. However, when adding flocculants, they are usually added directly to one place, which makes the flocculants unevenly dispersed in the wastewater. This makes it difficult for the flocculants to fully contact and react with the pollutants in the wastewater, thus reducing the wastewater purification effect. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Example: Figure 1-5 As shown, this utility model provides a chemical and pharmaceutical wastewater recycling device, including a mixing tank 1. A U-shaped plate 11 is fixedly installed at the top of the mixing tank 1. A first rotating shaft 12 rotatably passes through the middle of the U-shaped plate 11. A small gear 13 is fixedly installed at the bottom of the first rotating shaft 12. A large gear 14 is meshed with the outer side of the small gear 13. A feed pipe 15 is fixedly installed in the middle of the large gear 14. The bottom of the feed pipe 15 is inclined. The feed pipe 15 rotatably passes through the mixing tank 1 and the U-shaped plate 11. A feed hopper 16 is provided at the top of the feed pipe 15. A stirring shaft 17 rotatably passes through the middle of the mixing tank 1. Several sleeves are fixedly installed on the outside of the stirring shaft 17. Several annularly distributed stirring blades 1 are fixedly installed on the outside of the sleeves. 8. A water pump 2 is fixedly installed on one side of the mixing tank 1. Pipes 21 are fixedly installed at both ends of the water pump 2. One of the pipes 21 passes through the mixing tank 1 and is L-shaped. A processing tank 22 is provided on the side of the mixing tank 1 near the other pipe 21. A screening frame 23 is provided on the top of the processing tank 22. A drain pipe 24 is fixedly installed at the bottom of the processing tank 22. The first rotating shaft 12 is driven by the first motor, which is mounted on the U-shaped plate 11. The stirring shaft 17 is driven by the second motor, which is fixed at the bottom of the mixing tank 1. Neither the first motor nor the second motor is labeled in the attached drawings. The mixing tank 1 and the processing tank 22 are both supported by two sets of symmetrically distributed support legs (not labeled).
[0018] An L-shaped plate 3 is fixedly installed on one side of the top of the U-shaped plate 11. A connecting rod 31 is fixedly installed at the bottom of the L-shaped plate 3. Several annularly distributed fan-shaped plates 32 are fixedly installed at the bottom of the connecting rod 31. A disc 33 is fixedly installed between the hopper 16 and the discharge pipe 15. A fan-shaped groove 34 that works with the fan-shaped plates 32 is opened through the top of the disc 33.
[0019] Two symmetrically distributed fixing blocks 4 are fixedly installed on both sides of the screening box 23. A horizontal plate 41 is provided at the bottom of the fixing block 4 on each side. A guide rod 42 is fixedly installed at the bottom of the horizontal plate 41. A fixing plate 43 is slidably sleeved on the outside of the guide rod 42. The fixing plate 43 is fixedly connected to the processing box 22. A movable plate 44 is fixedly installed at the bottom of the guide rod 42. A second rotating shaft 45 is rotatably passed through the bottom of the processing box 22. An eccentric wheel 46 that cooperates with the movable plate 44 is fixedly installed on the outside of the second rotating shaft 45. The second rotating shaft 45 is located at the eccentric position of the eccentric wheel 46. By setting the second rotating shaft 45, when the second rotating shaft 45 rotates, it drives the eccentric wheel 46 to rotate. Since the eccentric wheel 46 cooperates with the movable plate 44 and the second rotating shaft 45 is at the eccentric position of the eccentric wheel 46, the rotation of the eccentric wheel 46 drives the guide rod 42 to move back and forth in the fixing plate 43. The movement of the guide rod 42 drives the horizontal plate 41 and the screening frame 23 to move up and down in the treatment box 22, thereby preventing the accumulation of flocculent sediment at the bottom of the screening frame 23, which would cause the screen holes of the screening frame 23 to become clogged and affect the separation of flocculent sediment from the treated wastewater. The second rotating shaft 45 is driven by the third motor, which is supported by the L-shaped support block fixedly connected to the treatment box 22. The third motor is not labeled in the attached drawing.
[0020] A spring 5 is fixedly installed between the horizontal plate 41 and the fixed plate 43. The spring 5 is located outside the guide rod 42. By setting the spring 5, the shaking frequency of the horizontal plate 41 and the screening box 23 is increased, and the shaking effect is improved.
[0021] An L-shaped block 6 is fixedly inserted through the bottom of the hopper 16. The L-shaped block 6 fits into the fan-shaped plate 32. By setting the L-shaped block 6, the flocculant in the hopper 16 is prevented from remaining on the fan-shaped plate 32, thus avoiding waste of flocculant.
[0022] The stirring blade 18 is curved, which increases the contact area and range of action between the stirring blade 18 and the wastewater and flocculant. During the stirring process, it can more effectively promote the formation of complex turbulence in the wastewater, so that the wastewater and flocculant are mixed more fully and evenly in the mixing tank 1.
[0023] Two symmetrically distributed threaded rods 7 are threadedly connected to the top of the horizontal plate 41. A pressure plate 71 is fixedly installed at the top of the threaded rods 7, and a rhomboid block 72 is fixedly installed at the top of the pressure plate 71. A slot 73 corresponding to the pressure plate 71 is opened through the top of the fixing block 4. By setting the threaded rods 7, when the screening frame 23 is placed into the processing box 22, the pressure plate 71, rhomboid block 72, and threaded rods 7 pass through the slot 73, so that the fixing block 4 is in contact with the horizontal plate 41. Then, the rhomboid block 72 is rotated, which drives the pressure plate 71 to move through the slot 72. When the clamping plate 71 and the threaded rod 7 rotate, the clamping plate 71 slowly moves towards the horizontal plate 41 as the threaded rod 7 rotates. When the clamping plate 71 is in contact with the horizontal plate 41 and the clamping plate 71 and the empty groove 73 form a cross shape, it means that the fixing block 4 and the horizontal plate 41 are fixed together. When disassembly is required, the operation can be reversed. The operation is simple and facilitates the installation and disassembly of the screening frame 23, allowing the screened flocculent sediment to be poured out.
[0024] The length and width of the empty slot 73 are slightly longer than the length and width of the horizontal pressing plate 71, which makes it easier for the pressing plate 71 to quickly pass through the empty slot 73, so that the screening frame 23 can be separated from the horizontal plate 41 and the screening frame 23 can be taken out from the processing box 22.
[0025] Working principle: In actual use, chemical and pharmaceutical wastewater is first added to mixing tank 1 through the inlet pipe on the upper surface of mixing tank 1. Then, a measured amount of flocculant is added to the discharge hopper 16. Simultaneously, the first motor is started, driving the first rotating shaft 12 and the small gear 13 to rotate. The rotation of the small gear 13 drives the large gear 14 to rotate, which in turn drives the discharge pipe 15, the disc 33, and the discharge hopper 16 to rotate. This ensures that the flocculant is not concentrated in one place during discharge, but can be discharged to other areas. During feeding, since the connecting rod 31 is fixedly connected to the sector plate 32 and the L-shaped plate 3, as the disc 33 rotates, the sector plate 32 and the sector groove 34 on the disc 33 gradually stop overlapping, causing the flocculant to fall from the sector groove 34 into the feeding pipe 15, and then be discharged from the feeding pipe 15 into the mixing box 1. This prevents too much flocculant from being fed at once, which is more conducive to the mixing of flocculant and wastewater in the later stage.
[0026] While adding flocculant, start the second motor to rotate the stirring shaft 17 and stirring blades 18 to purify the wastewater and flocculant. After purification, start the water pump 2 to extract the purified wastewater from the mixing tank 1, so that the purified wastewater and flocculent precipitate fall into the screening frame 23 to screen the flocculent precipitate and the treated wastewater. Then, under the action of the screening frame 23, the flocculent precipitate remains on the screening frame 23, and the cleaned wastewater falls directly into the bottom of the treatment tank 22 and is then discharged from the drain pipe 24.
[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
