Triethylaluminum has a burning effect on the human body, mainly damaging the respiratory tract and conjunctiva.

[0003] In the process of processing triethylaluminum, it needs to be diluted. The Chinese utility model patent with the publication number CN209362348U discloses a new type of dilution tank. The upper end of the dilution tank is provided with a flange cover plate, and one side of the upper end of the flange cover plate is connected with a stock solution inlet; the upper and lower ends of the side wall of the dilution tank are provided with a solvent inlet and a solution outlet; an isolation plate is arranged inside the dilution tank, a stirring motor is embedded in the middle of the isolation plate, and a stirring paddle is connected to the upper end of the stirring motor; the lower end of the isolation plate is welded with a sealed connection bracket, and the sealed connection bracket seals and wraps the stirring motor inside the isolation plate; and the lower end of the sealed connection bracket is connected with a telescopic connecting rod, and the telescopic connecting rod is connected with a hydraulic telescopic cylinder outside the bottom of the dilution tank. This utility model uses the isolation plate to regulate the upper dilution space in the dilution tank, gradually adjusts the upper dilution space according to the added amount of the liquid to be diluted, reduces the mixing cycle, and enables the solution to complete the proportioning and dilution in the shortest time.

[0004] However, during the use of this utility model, there is no corresponding metering mechanism. When the staff adds the liquid to be diluted into the dilution tank, since the liquid to be diluted and the diluent need to be mixed in a certain proportion, and in actual operation, it is necessary to intermittently add the corresponding liquid to complete the dilution work. Therefore, it is not convenient for the staff to control the added amount, which affects the dilution effect and cannot meet the production requirements. Thus, a dilution tank is proposed to solve the problems raised above. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a dilution tank, which has the advantage of facilitating quantitative feeding, and solves the problems that there is no corresponding metering mechanism. When the staff adds the liquid to be diluted into the dilution tank, since the liquid to be diluted and the diluent need to be mixed in a certain proportion, and in actual operation, it is necessary to intermittently add the corresponding liquid to complete the dilution work. Therefore, it is not convenient for the staff to control the added amount, which affects the dilution effect and cannot meet the production requirements.

[0006] To achieve the above object, the present utility model provides the following technical solution: A dilution tank, comprising a dilution tank body and a sealing cover plate arranged on the top of the dilution tank body. A liquid storage tank is arranged on one side of the dilution tank body, and a quantitative feeding mechanism is arranged between the liquid storage tank and the dilution tank body;

[0007] The quantitative feeding mechanism includes a conveying pipe fixedly connected to the bottom of the liquid storage tank and extending into the interior of the dilution tank body. A driving motor is fixedly connected to the side of the conveying pipe away from the dilution tank body. A driving shaft extending into the interior of the conveying pipe is fixedly connected to the output shaft of the driving motor, and two baffle plates are fixedly connected to the outside of the driving shaft.

[0008] Further, a feeding pipe communicating with the interior thereof is fixedly connected to the top of the liquid storage tank, and a scale line is fixedly connected to the front surface of the liquid storage tank.

[0009] Further, triethylaluminum liquid is arranged inside the liquid storage tank. The two baffle plates are symmetrically distributed on the top and bottom of the driving shaft, and the sides of the two baffle plates away from the driving shaft are in contact with the inner wall of the conveying pipe.

[0010] Further, a servo motor is fixedly installed on the top of the sealing cover plate. A rotating shaft extending into the interior of the dilution tank body is fixedly connected to the output shaft of the servo motor, and stirring blades are fixedly connected to the outside of the rotating shaft.

[0011] Further, a heat insulation layer is fixedly connected to the inner wall of the dilution tank body. A thermometer and a pressure gauge extending into the interior of the dilution tank body are respectively fixedly installed on the top of the sealing cover plate.

[0012] Further, fixing blocks are fixedly connected to one side of the sealing cover plate and the dilution tank body respectively. A fixing bolt penetrating through the bottom fixing block is threadedly connected to the top fixing block.

[0013] Further, a liquid injection pipe communicating with the interior of the dilution tank body is fixedly connected to the top of the sealing cover plate, and a blanking pipe communicating with the interior thereof is fixedly connected to the bottom of the dilution tank body.

[0014] Further, a support seat is fixedly connected to the bottom of the dilution tank body. The number of the support seats is four, and the four support seats are evenly distributed at the four corners of the bottom of the dilution tank body.

[0015] Compared with the prior art, the present utility model provides a dilution tank, which has the following beneficial effects:

[0016] 1. The dilution tank can store the triethylaluminum liquid by setting up a liquid storage tank. At the same time, through the setting of a delivery pipe, the triethylaluminum liquid inside the liquid storage tank can be transported into the interior of the dilution tank body, thereby achieving the effect of diluting the triethylaluminum liquid. By setting a driving motor to drive two baffle plates to rotate simultaneously, when the two baffle plates are in a horizontal state, the flow of the triethylaluminum liquid can be blocked. When the two baffle plates are in a vertical state, the triethylaluminum liquid can enter the interior of the dilution tank body. Workers only need to control the working interval of the driving motor to complete the effect of quantitative feeding.

[0017] 2. The dilution tank is provided with a heat insulation layer. Since heat is easily generated during the stirring and dilution of the triethylaluminum liquid, the heat insulation layer can prevent part of the heat from being conducted to the dilution tank body, thereby minimizing the risk of scalding workers. At the same time, by setting a thermometer and a pressure gauge, the temperature change inside the dilution tank body can be observed in real time to avoid accidents caused by overheating. It solves the problem that there is no corresponding quantitative mechanism. When workers add the liquid to be diluted into the dilution tank, since the liquid to be diluted and the diluent need to be mixed in a certain proportion, and in actual operation, corresponding liquids need to be added intermittently to complete the dilution work, it is not convenient for workers to control the addition amount, affecting the dilution effect and not meeting the production requirements.
