These waste liquids usually contain harmful substances, and if directly discharged without proper treatment, they will have a serious impact on the environment and human health. Depending on different treatment processes and technologies, waste liquid recovery devices for chemical engineering and chemistry can be classified into various types, including but not limited to: Physical treatment type: By physical methods, such as grille filtration, grit chambers, and sedimentation tanks, etc., to remove large particle suspensions, precipitates, etc. from the waste liquid. Chemical treatment type: Using chemical agents to react with pollutants in the waste liquid to form precipitates or aggregates, thereby achieving the purification and recovery of the waste liquid. Biological treatment type: Utilizing the metabolic action of microorganisms to convert organic substances in the waste liquid into stable inorganic substances to achieve the purpose of purifying the waste liquid. Comprehensive treatment type: Combining multiple treatment methods such as physical, chemical, and biological to conduct a more comprehensive treatment and recovery of the waste liquid.

[0003] There are some deficiencies in the use of existing waste liquid recovery devices for chemical engineering and chemistry, which are specifically as follows:

[0004] When using an existing waste liquid recovery device for chemical engineering and chemistry, by concentrating the collected waste liquid for chemical engineering and chemistry in a sedimentation tank, to ensure the effective removal of suspended solids in the waste liquid for chemical engineering and chemistry, it is necessary to inject alum into the waste liquid for chemical engineering and chemistry, and then after standing, the supernatant is discharged for the next treatment to complete the removal of suspended solids in the waste liquid for chemical engineering and chemistry. However, when the existing device is in use, alum cannot be evenly mixed into the waste liquid for chemical engineering and chemistry, and stirring is required, and the height of the drain outlet cannot be adjusted according to the amount of suspended solids, which is not convenient for discharging the supernatant. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a waste liquid recovery device for chemical engineering and chemistry to solve the problems existing in the above-mentioned background art.

[0006] To achieve the above object, a chemical and chemical industrial waste liquid recovery device is designed, including a waste liquid mixing tank 1.

A clear liquid discharging component 4 is installed on one side of the waste liquid mixing tank 1, and the clear liquid discharging component 4 is installed on the outer surface of the waste liquid mixing tank 1. The bottom of the transmission component 2 is fixedly connected to the output shaft of a servo motor 5; the waste liquid mixing tank 1 includes a positioning and sealing tank 101. A first sliding notch 102 is opened at the bottom on one side of the positioning and sealing tank 101. First sliding grooves 103 are opened on the front and back of the first sliding notch 102. The top of the positioning and sealing tank 101 is fixedly connected to a waste liquid tank 104.

A second sliding notch 105 is opened at the bottom on one side of the waste liquid tank 104. Second sliding grooves 106 are opened on the front and back of the second sliding notch 105.

[0007] Furthermore, the transmission component 2 includes a rotating shaft 201. A positioning bearing 202 is fixedly installed at the bottom outside the rotating shaft 201.

The top of the first positioning circular plate 203 is fixedly connected to a transmission column 204. The top of the transmission column 204 is fixedly connected to a second positioning circular plate 205.

[0008] Furthermore, the stirring component 3 includes a transmission belt 301. Stirring plates 302 are fixedly connected to the outside of the transmission belt 301. The stirring plates 302 are arranged vertically and are evenly distributed circumferentially around the transmission belt 301.

[0009] Furthermore, the shape and size of the outside of the top of the positioning and sealing tank 101 are the same as the shape and size of the bottom of the waste liquid tank 104. There is an interference fit between the diameter of the circular positioning hole 107 and the outside diameter of the positioning bearing 202.

[0010] Furthermore, the diameter difference between the second positioning circular plate 205 and the transmission column 204 is the same as the thickness of the transmission belt 301. The middle part of the transmission column 204 and the middle part inside the waste liquid tank 104 are in the same plane.

[0011] Furthermore, the width of the second sliding notch 105 is the same as the width of the first sliding notch 102. The cross-sectional shape and size of the second sliding groove 106 are the same as the cross-sectional shape and size of the first sliding groove 103.

[0012] Furthermore, the supernatant discharge assembly 4 includes a lifting plate 401. On the front and back sides of the lifting plate 401, first limiting plates 402 are fixedly connected. On the side of the first limiting plate 402 away from the lifting plate 401, a second limiting plate 403 is fixedly connected.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] (1) When the present invention recycles and treats chemical and chemical industrial waste liquid, the chemical and chemical industrial waste liquid is discharged into the inner side of the waste liquid tank, and then alum is added into the positioning and sealing box. Then, the servo motor works to drive the rotating shaft to rotate, and then drives the first positioning circular plate, the transmission column, and the second positioning circular plate to rotate. Under the action of the friction force between the transmission column and the inner side of the transmission belt, the transmission belt and the stirring plate are driven to rotate, so that the stirring plate mixes the chemical and chemical industrial waste liquid and alum inside the waste liquid tank, enabling the alum and the chemical and chemical industrial waste liquid to be fully mixed. Then, by standing the mixed liquid, the alum can adsorb the suspended matter, so as to achieve the purpose of removing the suspended matter in the chemical and chemical industrial waste liquid, facilitating the full mixing of the alum and the chemical and chemical industrial waste liquid, and ensuring the mixing efficiency;

[0016] (2) After the alum in the mixed liquid settles, the upper-layer supernatant can be discharged through the discharge pipe. Then, after the liquid drops below the position where the discharge pipe is located, the position of the discharge pipe can be adjusted by sliding the lifting plate, the first limiting plate, and the second limiting plate in the first sliding groove and the second sliding groove, facilitating the discharge of the suspension, and worthy of popularization and application.

Under the action of the frictional force between the transmission column 204 and the inner side of the transmission belt 301, the transmission belt 301 and the stirring plates 302 are driven to rotate, so that the stirring plates 302 mix the chemical and chemical industrial waste liquid and alum inside the waste liquid tank 104, enabling the alum and the chemical and chemical industrial waste liquid to be fully mixed. Then, by allowing the mixed liquid to stand still, the alum can adsorb the suspended matter, thereby achieving the purpose of removing the suspended matter in the chemical and chemical industrial waste liquid, facilitating the full mixing of the alum and the chemical and chemical industrial waste liquid, and ensuring the mixing efficiency.

[0032] The working principle of the present invention is as follows: when recycling and treating chemical and chemical industrial waste liquid, the chemical and chemical industrial waste liquid is discharged into the inner side of the waste liquid tank 104, and then alum is added into the positioning and sealing box 101. Then, the servo motor 5 works to drive the rotating shaft 201 to rotate, and then drives the first positioning circular plate 203, the transmission column 204 and the second positioning circular plate 205 to rotate. Under the action of the frictional force between the transmission column 204 and the inner side of the transmission belt 301, the transmission belt 301 and the stirring plate 302 are driven to rotate, so that the stirring plate 302 mixes the chemical and chemical industrial waste liquid and alum on the inner side of the waste liquid tank 104, enabling the alum and the chemical and chemical industrial waste liquid to be fully mixed. Then, by standing the mixed liquid, the alum can adsorb the suspended matter, so as to achieve the purpose of removing the suspended matter in the chemical and chemical industrial waste liquid, facilitating the full mixing of the alum and the chemical and chemical industrial waste liquid, and ensuring the mixing efficiency;

[0033] After the alum in the mixed liquid settles, the upper clear liquid can be discharged through the discharge pipe 404.
