Meanwhile, the return spring can effectively prevent excessive impact pressure from damaging the inside of the material box. In addition, crushing the alkaline neutralizing agent can effectively improve the mixing efficiency of the medium, thereby improving work efficiency. Attached Figure Description

Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-4 This utility model provides a technical solution for an acidic wastewater treatment device: Example

[0025] according to Figure 1 , Figure 2 and Figure 3 , Figure 4 As shown, an acidic wastewater treatment device includes a mixing tank 1. An inlet 2 is fixedly connected to the top of the mixing tank 1, and a filter plate 3 is fixedly connected inside the inlet 2. A top plate 4 is fixedly connected to the side of the mixing tank 1 away from the inlet 2, and a stirring mechanism 5 is fixedly connected inside the top plate 4. A support plate 6 is fixedly connected to one side of the mixing tank, and a grinding mechanism 7 is fixedly connected inside the support plate 6. A feed hopper 8 is fixedly connected to the top of the grinding mechanism 7. A controller 9 is fixedly connected to the outer wall of the mixing tank 1, and a base 10 is fixedly connected to the bottom of the mixing tank 1.

[0026] In practical use, this acidic wastewater treatment equipment introduces a medium that enters through inlet 2. The medium is filtered by filter plate 3 to remove solids. Once the medium flows into mixing tank 1, an alkaline neutralizing agent is added to feed hopper 8. After the neutralizing agent flows into material box 706, motor 701 is activated. Motor 701 drives folding rod 703, which in turn moves pressure rod 704 left and right. Simultaneously, pressure plate 705 moves synchronously, crushing the neutralizing agent. Return spring 702 effectively prevents excessive pressure from damaging the inside of material box 706. Furthermore... Crushing the alkaline neutralizer can effectively improve the mixing efficiency of the medium with it, thereby improving work efficiency. After the neutralizer falls through the channel, the motor 501 can be controlled to rotate. The motor 501 will drive the gear 502 to rotate, and the gear 503 will also rotate at the same time. The gear 503 will then drive the transmission rod 505 to rotate. When the transmission rod 505 rotates, its bottom end will drive the stirring rod 506 to rotate inside the mixing box 1. When the stirring rod 506 rotates, the toothed groove at the top will rotate under the action of the toothed ring 504, thereby improving the mixing efficiency of the medium and the alkaline neutralizer, making it more uniform and reducing the inconvenience caused by rework later. Example

[0027] Based on Example 1, such as Figure 2 and Figure 3 As shown, the stirring mechanism 5 includes a motor 501, a gear 502, a gear 503, a gear ring 504, a transmission rod 505, and a stirring rod 506. The output end of the motor 501 is fixedly connected to the top of the gear 502. The gear 503 is fixedly connected to the outer wall of the transmission rod 505. The gear 502 and the gear 503 mesh with each other. The top of the stirring rod 506 is rotatably connected to the bottom of the transmission rod 505. The top of the stirring rod 506 has a toothed groove, and the top of the stirring rod 506 is movably connected to the opposite side of the transmission rod 505 and the gear ring 504. The top of the stirring rod 506 meshes with the gear ring 504. The output end of the motor 501 extends into the interior of the mixing chamber 1. The top of the motor 501 is fixedly connected to the top of the interior of the top plate 4. The top of the transmission rod 505 extends into the exterior of the mixing chamber 1 and is rotatably connected to the bottom of the top plate 4. The stirring rod 506 is movably connected into the interior of the mixing chamber 1.

[0028] Once the neutralizing agent falls through the channel, motor 501 can be controlled to rotate. Motor 501 drives gear 502 to rotate, and gear 503 also rotates simultaneously. Gear 503 then drives transmission rod 505 to rotate. When transmission rod 505 rotates, its bottom end drives stirring rod 506 to rotate inside mixing box 1. When stirring rod 506 rotates, the toothed groove at its top will rotate under the action of toothed ring 504, thereby improving the mixing efficiency of the medium and alkaline neutralizing agent, making the mixing more uniform, and reducing the inconvenience caused by rework later.

The output end of the second motor 701 is fixedly connected to one end of the folding rod 703, and the other end of the folding rod 703 is hinged to the outer wall of the pressure rod 704. Two springs 702 are provided symmetrically, and one end of the spring 702 is fixedly connected to the inner wall of the pressure rod 704. One end of the pressure rod 704 is fixedly connected to the outer wall of the pressure plate 705. The pressure plate 705... 5 is movably connected to the inside of the material box 706, the other end of the spring 702 is fixedly connected to one side of the mixing box 1, the motor 701 is fixedly connected to the inner wall of the support plate 6, one end of the pressure rod 704 passes through the outer wall of the mixing box 1 and extends into the inside of the material box 706, one side of the material box 706 is fixedly connected to the top of the inside of the mixing box 1, and the bottom of the material box 706 is provided with multiple through slots, the top of the mixing box 1 is fixedly connected to the bottom of the feed hopper 8, and the feed hopper 8 and the material box 706 are interconnected.

[0030] After the medium enters through the inlet 2, it is filtered by the filter plate 3 to remove solids. Once the medium flows into the mixing tank 1, an alkaline neutralizing agent can be added to the feed hopper 8. After the alkaline neutralizing agent flows into the material box 706, the motor 701 can be controlled to operate. When the motor 701 operates, it drives the folding rod 703 to move, which in turn drives the pressure rod 704 to move left and right. At the same time, the pressure plate 705 also moves synchronously to crush the alkaline neutralizing agent. Meanwhile, the return spring 702 can effectively prevent excessive impact pressure from damaging the inside of the material box 706. In addition, crushing the alkaline neutralizing agent can effectively improve the mixing efficiency of the medium, thereby improving work efficiency.
