[0002] Chemical waste liquid is wastewater containing various chemical substances generated during the production process of the chemical industry. These wastewaters may contain harmful substances, dissolved solids, by-products generated by chemical reactions, etc. In order to protect the environment and the sustainable utilization of resources, the impurity layering separation device used therein plays an important role in the treatment of chemical waste liquid. This device can separate various impurities in the wastewater into different layers according to the density, solubility or other physical and chemical properties of different substances.

[0003] After retrieval, the existing Chinese patent (publication number: CN218774355U) discloses a device for separating impurities in chemical waste liquid by layering. This device for separating impurities in chemical waste liquid has two working modes, can separate the impurities in the chemical waste liquid from top to bottom, and can also separate the waste liquid of the specified layer, which is convenient for the staff to analyze the impurities in each layer of waste liquid, so as to formulate more appropriate process means, and the whole separation process is in a closed state.

[0004] The above-mentioned device for separating impurities in waste liquid by layering has difficulty in separating the waste liquid layer by layer in terms of solving the fluid flow characteristics. The technical solution adopts the method of covering the liquid surface with a steady flow plate and a balance floating plate, so that the liquid reaches a stable state, but the precipitation process of impurities still takes a long time, which will reduce the efficiency of the whole treatment process. Therefore, we propose a device for separating impurities in chemical waste liquid to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a device for separating impurities in chemical waste liquid by layering.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme: a device for separating impurities in chemical waste liquid by layering, including a box body, and a precipitation component is fixedly connected to the bottom end of the inner wall of the box body;

[0007] The precipitation component includes a liquid storage tank, a water pump, a right-angle plate, a motor, a transmission column, and a stirring blade. The bottom end of the liquid storage tank is fixedly connected to the bottom end of the inner wall of the box body. The input end of the water pump is fixedly connected to the liquid storage tank. The output end of the water pump is fixedly connected to the right-angle plate. The bottom end of the motor is fixedly connected to the top end of the box body and is in transmission connection with the transmission column. One end of the stirring blade away from the box body is fixedly connected to the transmission column.

[0008] As a further description of the above technical solution: A frame is fixedly connected to the outside of the box body. A screening component is fixedly connected to the inner wall of the frame. A filter plate is arranged inside the screening component. The outside of the filter plate is slidably connected to the inner wall of the frame. Fixed blocks are fixedly connected to both sides of the top of the frame. A telescopic column is slidably connected inside the fixed block. A fixed column is fixedly connected to the inner wall of the fixed block. A spring is sleeved outside the telescopic column. A limiting block is fixedly connected to the side of the telescopic column close to the fixed column.

[0009] As a further description of the above technical solution: One end of the spring is fixedly connected to the limiting block, and the other end of the spring is fixedly connected to the inner wall of the fixed block. The outside of the limiting block is slidably connected to the fixed block. The limiting block is engaged with the groove on the filter plate.

[0010] As a further description of the above technical solution: A cylinder is installed on one side of the top of the box body away from the motor. The driving end of the cylinder is fixedly connected to a door panel, and the door panel is slidably connected to the inner wall of the box body.

The water pump then circulates the precipitated liquid to further improve the separation efficiency. This setting improves the separation efficiency of impurities, solves the problem of long time required for separating impurities in the prior art, and can also achieve more precise hierarchical separation, so as to take more appropriate treatment measures for different impurities.

[0015] The chemical waste liquid impurity stratification separation device designed by the utility model, through the cooperation of components such as a screening component and a frame, filters the stratified waste water through a filter plate, and then pulls up the filter plate to clean the waste on the surface of the filter plate, realizing the effective separation of chemical waste liquid, improving the waste liquid treatment efficiency, and ensuring environmental safety.

[0023] Embodiment 1

[0024] Referring to Figure 1 - Figure 3 and Figure 5 , a chemical waste liquid impurity stratification separation device provided by the present utility model: includes a box body 1, and a precipitation component 2 is fixedly connected to the bottom end of the inner wall of the box body 1;

[0025] The precipitation assembly 2 includes a liquid storage tank 201, a water pump 202, a right-angled plate 203, a motor 204, a transmission column 205, and a stirring blade 206. The bottom end of the liquid storage tank 201 is fixedly connected to the bottom end of the inner wall of the box body 1. The input end of the water pump 202 is fixedly connected to the liquid storage tank 201, and the output end of the water pump 202 is fixedly connected to the right-angled plate 203. The bottom end of the motor 204 is fixedly connected to the top end of the box body 1 and is in transmission connection with the transmission column 205. One end of the stirring blade 206 away from the box body 1 is fixedly connected to the transmission column 205. The design of the precipitation assembly 2 helps to directly introduce the waste liquid into the precipitation assembly 2, which is conducive to the effective separation of impurities in the waste liquid by precipitation. The design of the box body 1 ensures the sealing of the waste liquid during the treatment process. The connection between the liquid storage tank 201 and the water pump 202 enables the water pump 202 to directly extract the precipitation liquid from the liquid storage tank 201. The design of the right-angled plate 203 divides the interior of the box body 1 into two regions. At the same time, the output end of the water pump 202 is connected to the right-angled plate 203, so that the precipitation liquid sucked out by the water pump 202 flows into the chemical waste liquid. The precipitation liquid can use calcium hydroxide, aluminum hydroxide, sodium sulfide, etc., which can be specifically used according to requirements. The power of the motor 204 is transmitted to the stirring blade 206 through the transmission column 205, causing the stirring blade 206 to rotate upward in the waste liquid. The upward-rotating stirring blade 206 can form a vortex or eddy current in the liquid waste, thereby promoting the faster settlement of the precipitated impurities;

[0026] One side of the right-angled plate 203 away from the transmission column 205 is fixedly connected with an inclined plate 6. The outer side of the inclined plate 6 is fixedly connected to the inner wall of the box body 1. Fixing the inclined plate 6 on the right-angled plate 203 and the inner wall of the box body 1 gives the inclined plate 6 a stable support, ensuring that the liquid flows into the designated area through the guidance of the inclined plate 6 when entering the interior of the box body 1 through the liquid inlet 9;

[0027] The outer side of the liquid storage tank 201 is fixedly connected with a liquid injection port 7 and extends outward through the inner wall of the box body 1. The four corners of the bottom end of the box body 1 are fixedly connected with support columns 8. One side of the top end of the box body 1 away from the cylinder 4 is fixedly connected with a liquid inlet 9. The existence of the liquid injection port 7 makes it more convenient to inject liquid into the liquid storage tank 201 when needed. The existence of the support columns 8 provides additional support for the bottom end of the box body 1, which helps to enhance the stability of the entire structure. The existence of the liquid inlet 9 provides an inlet when it is necessary to inject waste liquid into the box body 1.

[0028] Embodiment 2

[0029] On the basis of Embodiment 1, refer to Figure 1 - Figure 5, A chemical waste liquid impurity stratification separation device provided by the utility model: A frame 10 is fixedly connected to the outside of the box body 1. A screening component 3 is fixedly connected to the inner wall of the frame 10. A filter plate 301 is arranged inside the screening component 3. The outside of the filter plate 301 is slidably connected to the inner wall of the frame 10. Fixed blocks 302 are fixedly connected to both sides of the top of the frame 10. A telescopic column 303 is slidably connected to the inside of the fixed block 302. A fixed column 304 is fixedly connected to the inner wall of the fixed block 302. A spring 305 is sleeved on the outside of the telescopic column 303. A limiting block 306 is fixedly connected to the side of the telescopic column 303 close to the fixed column 304. The design of the frame 10 on the outside of the box body 1 enables the processed waste liquid to flow out of the box body 1 from the inside of the frame 10 and provides a carrier for the screening component 3. Two filter plates 301 are provided to improve the filtering effect. When one of the filter plates 301 is cleaning the sediment, the other filter plate 301 can be used for filtering. The engagement design of the groove and the limiting block 306 ensures the stable position of the limiting block 306 and prevents it from sliding or being displaced during operation. The connection between the spring 305 and the fixed block 302 ensures the firm position of the spring 305, enabling the spring 305 to achieve a rebounding effect and ensuring that the groove on the filter plate 301 can be engaged during the upward movement of the filter plate 301;

[0030] One end of the spring 305 is fixedly connected to the limiting block 306, and the other end of the spring 305 is fixedly connected to the inner wall of the fixed block 302. The outside of the limiting block 306 is slidably connected to the fixed block 302. The limiting block 306 is engaged with the groove on the filter plate 301. The spring 305 is used to provide elastic support or compressive force. The limiting block 306 has a certain movement range on the fixed block 302, and the movement range of the filter plate 301 is restricted by engaging with the limiting block 306 through the groove on the filter plate 301. The filter plate 301 is designed in an L shape and pulls up the precipitated lumps together when sliding upward along the frame 10. The two filter blocks are in sequence without affecting the discharge of chemical waste water;

[0031] A cylinder 4 is installed on one side of the top of the box body 1 away from the motor 204. The driving end of the cylinder 4 is fixedly connected to a door panel 5. The door panel 5 is slidably connected to the inner wall of the box body 1. By connecting the driving end of the cylinder 4 to the door panel 5, the cylinder 4 can achieve corresponding movements by pushing and pulling the door panel 5 to maintain the sealing of the box body 1.

[0032] Working principle: Firstly, when the waste liquid needs to be treated, it is injected into the interior of the box body 1 through the liquid inlet 9 and guided by the inclined plate 6 into the designated area. The water pump 202 starts to work, directly extracting the precipitation liquid from the liquid storage tank 201 and guiding it into the precipitation area in the box body 1 through the right-angle plate 203. The precipitation liquid is mixed with the chemical waste liquid, and impurities will thus be separated more effectively. While precipitating and mixing, the motor 204 starts to drive the transmission column 205, and the transmission column 205 drives the stirring blade 206 to rotate upward in the waste liquid, forming a vortex or eddy current, thereby accelerating the sedimentation of impurities in the waste liquid. Next, the treated waste liquid will flow out of the box body 1 through the interior of the frame 10 and enter the screening assembly 3. When the filter plate 301 slides upward, under the action of the spring 305, the limit block 306 is engaged with the groove on the filter plate 301, and then the solid impurities remaining in the liquid are cleaned. Finally, after the treatment is completed, the telescopic column 303 is pulled to drive the limit block 306 to disengage from the groove of the filter plate 301, and the filter plate 301 can fall into the frame 10. The air cylinder 4 will push the door panel 5 to maintain the sealing of the box body 1 and prevent the chemical waste liquid from leaking.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
