[0021] 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.

[0022] Example 1

[0023] Please refer to Figure 1-7 As shown, this utility model provides a mixing device for adding wastewater treatment agents, including a mixing tank 1 and a tank cover 2. The mixing tank 1 and the tank cover 2 are detachably connected. The top of the tank cover 2 is provided with an inlet 3 for easy wastewater injection. The side of the mixing tank 1 near the bottom is provided with a drain outlet 14 for easy discharge of treated wastewater. The top of the tank cover 2 is provided with a liquid injection port 4 on the side of the inlet 3. A crushing box 5 is provided on the side of the liquid injection port 4. The top of the crushing box 5 is provided with a feed inlet 6. The bottom of the crushing box 5 passes through the interior of the tank cover 2. The inner side of the crushing box 5 is provided with a crushing mechanism for easy crushing of solid drugs. The bottom of the tank cover 2 is equipped with a high-efficiency stirring mechanism for easy mixing of drugs and wastewater.

[0024] Specifically, when the mixing device is working, wastewater can be injected into the mixing tank 1 through the injection port 3 at the top of the tank cover 2. Solid drugs enter through the feed port 6 at the top of the crushing box 5, are crushed by the crushing mechanism inside the crushing box 5, and fall into the tank. Liquid drugs can be injected through the drug injection port 4. Then, the high-efficiency stirring mechanism at the bottom of the tank cover 2 is activated, which can fully mix the drugs and wastewater in the mixing tank 1. The treated wastewater can be discharged from the drain port 14 near the bottom on one side of the mixing tank 1. Thus, through the above structure, the drug dissolution efficiency and mixing uniformity can be improved, ensuring the effect of wastewater treatment.

[0025] The high-efficiency stirring mechanism includes a main stirring blade and auxiliary stirring blades. A groove 15 is provided at the bottom of the tank cover 2. A second motor 16 is installed at the center of the top of the tank cover 2. The output end of the second motor 16 extends to the inner side of the groove 15 and is connected to a rotating plate 17. A rotating shaft 18 is rotatably connected to one end of the rotating plate 17. A spur gear 19 is connected to one end of the rotating shaft 18. An internal gear ring 20 that meshes with the spur gear 19 is embedded in the inner side of the groove 15. The main stirring blade is fitted onto the outer ring of the rotating shaft 18. Multiple sets of auxiliary stirring blades are installed on the outer surface of the rotating shaft 18. The main stirring blade is a ribbon stirring blade 21, which is fitted onto the outer ring of the rotating shaft 18. The auxiliary stirring blades are inclined stirring blades 22, and the multiple sets of stirring blades 22 are evenly distributed. The rotating shaft 18 is mounted on the outer surface of the rotating shaft 18. By starting the second motor 16, its output end can drive the rotating plate 17 to rotate within the groove 15. When the rotating plate 17 rotates, it can drive the rotating shaft 18 to revolve around the center of the groove 15. At the same time, the spur gear 19 at one end of the rotating shaft 18 meshes with the internal gear ring 20, which can cause the rotating shaft 18 to rotate on its own axis. This causes the spiral ribbon stirring paddle 21 and the evenly distributed inclined stirring blades 22, which are sleeved on the outer ring of the rotating shaft 18, to revolve and rotate simultaneously. The spiral ribbon stirring paddle 21 forms an axial stirring flow, and the inclined stirring blades 22 form radial and tangential stirring flows. This can achieve multi-dimensional and efficient mixing of drugs and wastewater. By setting it up, it can effectively promote the uniform mixing of drugs and wastewater, thereby improving the wastewater treatment effect.

[0026] The pulverizing mechanism includes pulverizing rollers 7. Two sets of pulverizing rollers 7 are provided inside the pulverizing box 5. A connecting shaft 8 passes through the interior of each set of pulverizing rollers 7. One end of each set of connecting shafts 8 is rotatably connected to the pulverizing box 5, and the other end of each set of connecting shafts 8 extends to the outside of the pulverizing box 5 and is connected to a transmission gear 9. The two sets of transmission gears 9 mesh with each other. One side of one set of transmission gears 9 is connected to the output end of the first motor 10. The first motor 10 is mounted on the top of the mounting base 11, which is located on one side of the pulverizing box 5. By starting the first motor 10, its output end can drive the transmission gear 9 connected to it to rotate. This transmission gear 9 meshes with the other set of transmission gears 9, thereby driving the two sets of connecting shafts 8 to rotate. The two sets of connecting shafts 8 can drive the two sets of pulverizing rollers 7 to rotate. The two sets of pulverizing rollers 7 rotate relative to each other, which can squeeze and pulverize the solid medicine entering from the feed port 6 and then drop it into the mixing tank 1 to facilitate rapid mixing of the medicine. Thus, by setting up this mechanism, the drug dissolution efficiency and wastewater treatment effect are improved.

[0027] The inner walls of both sides of the pulverizing box 5 are equipped with mounting brackets 12. One end of each mounting bracket 12 is fitted with a brush 13 by bolts. The two sets of brushes 13 are respectively attached to the two sets of pulverizing rollers 7. The brushes 13 on the mounting brackets 12 on both sides of the pulverizing box 5 are attached to the pulverizing rollers 7, which can remove the drug residues attached to the surface of the pulverizing rollers 7 in time when the pulverizing rollers 7 rotate, avoid the accumulation of materials affecting the pulverizing effect and equipment operation, and effectively maintain the working efficiency and stability of the pulverizing mechanism.

[0028] The mixing tank 1 is equipped with four sets of support legs 23 at the bottom, and each set of support legs 23 is equipped with a universal wheel 24 with brakes at the bottom. Handles 25 are installed on both sides of the mixing tank 1. The four sets of universal wheels 24 with brakes at the bottom of the mixing tank 1, together with the support legs 23, facilitate the movement of the device. The handles 25 on both sides make it easy to carry and can flexibly adjust the position of the device to meet the needs of different sewage treatment scenarios.

[0029] Working principle: First, wastewater is injected into the mixing tank 1 through inlet 3. Solid drugs are fed into the crushing box 5 through inlet 6. Then, the first motor 10 is started, and its output can drive the transmission gear 9 connected to it to rotate. This transmission gear 9 meshes with another set of transmission gears 9, thereby driving the two sets of connecting shafts 8 to rotate. The two sets of connecting shafts 8 can drive the two sets of crushing rollers 7 to rotate. The two sets of crushing rollers 7 rotate relative to each other, which can crush the solid drugs and make them fall into the mixing tank 1. Liquid drugs can be injected from the liquid injection port 4. Then, by starting the second motor 16, its output can drive the rotating plate 17 to rotate... Rotating within the groove 15, the rotating plate 17 drives the rotating shaft 18 to revolve around the center of the groove 15. Simultaneously, the circular gear 19 at one end of the rotating shaft 18 meshes with the internal gear ring 20, causing the rotating shaft 18 to rotate on its own axis. This causes the spiral ribbon stirring paddle 21, which is sleeved on the outer ring of the rotating shaft 18, and the evenly distributed inclined stirring blades 22 to simultaneously revolve and rotate. The spiral ribbon stirring paddle 21 forms an axial stirring flow, and the inclined stirring blades 22 form radial and tangential stirring flows. This allows for the multi-dimensional and efficient mixing of the drug and wastewater. The treated wastewater can be discharged from the drain outlet 14, thus completing the entire operation process.
