[0002] Evaporated concentrated black liquor refers to a liquid with a high degree of concentration and a black color. It is usually produced in the process of concentrating raw materials or products in the chemical, petroleum, pharmaceutical and other industries. The black color of this liquid is due to the fact that it contains a large amount of dissolved substances, such as organic matter, inorganic salts, etc., which make its color darker. When evaporating concentrated black liquor, a flash tank is required. The flash tank is a device used in the distillation or evaporation process. It is commonly used in the chemical and other industries to separate the volatile components in the liquid. Usually, the flash tank has multiple injection pipelines. When injecting liquid, different pipeline connections need to be replaced, which is laborious to adjust and has poor practicality. Utility Model Content

[0018] The liquid in the external liquid supply pipe is collected through the liquid inlet 1 and sent to the liquid separation cylinder 3 through the lower liquid pipe 2. At this time, the liquid will be discharged through the conical through hole on the surface of the turntable 5 through the discharge pipe 6. The discharge pipe 6 faces different liquid separation structures 8. During the use of the discharge pipe 6, the liquid will be sent to different liquid injection ports of the flash tank through the liquid separation structure 8 depending on which end the discharge pipe 6 faces. The rotation of the turntable 5 is controlled by the power structure 7, so as to adjust the direction of liquid separation, saving labor. The motor is a servo motor, which can be programmed as needed, easy to use, and highly practical. The bottom end of the lower liquid pipe 2 is expanded by the action of the liquid storage cone 9, which can avoid frequent filling of the pipeline and ensure the smooth use of the equipment.

[0019] The power structure 7 includes a rotating shaft 71, which is rotatably assembled on the inner wall of the liquid separation cylinder 3.

[0020] When the power structure 7 needs to be used, the motor 74 is first turned on, and the second bevel gear 73 is driven to rotate through the motor shaft. At this time, the second bevel gear 73 will drive the first bevel gear 72 meshing with it to rotate.
