Description

Technical Field

[0001] The utility model relates to the technical field of liquid dispensing tanks, in particular to a liquid dispensing tank capable of quantitatively feeding materials. Background Art

[0002] Liquid preparation tank, also known as preparation tank or blending tank, is a mixing and stirring container for mixing one or several materials according to the process ratio. Liquid preparation tank has different names according to different uses. It is used in pharmaceutical liquid preparation system and is often called liquid preparation tank, concentrated preparation tank, dilute preparation tank, stainless steel liquid preparation tank, sanitary grade liquid preparation tank, injection liquid preparation tank, pharmaceutical sanitary grade liquid preparation tank, etc.

[0003] Common quantitative liquid preparation tanks usually have a measuring cylinder installed at the liquid inlet. The staff first pours the original liquid into the measuring cylinder, and by observing the scale lines on the measuring cylinder, they can pour the required volume, then open the valve inside the measuring cylinder to pour the original liquid into the liquid preparation tank, and repeat the operation for the next original liquid until all the original liquids are prepared, and finally mix them. However, in this way, the staff needs to pour the liquid every time the liquid is prepared, which is work-intensive. In addition, the next time the liquid is prepared, since the liquid preparation tank does not have the function of cleaning the inner wall and the stirring rod, the solution attached to the inner wall of the liquid preparation tank and the stirring rod will affect the accuracy of the liquid preparation.

[0004] Therefore, the utility model designs a liquid dispensing tank capable of quantitative feeding to solve the problems existing in the prior art. Utility Model Content

[0005] The utility model aims to provide a liquid dispensing tank capable of quantitatively feeding materials, so as to solve the problems raised in the above-mentioned background technology.

[0007] Preferably, the feeding mechanism includes a feeding hopper, which is fixed on one side of the top of the tank body. The outer wall of the feeding hopper is provided with a transparent scale, and the bottom of the feeding hopper is provided with a feeding pipe connected to the tank body. The raw liquid is poured into the feeding hopper, and the required volume can be poured through the transparent scale to achieve a quantitative effect.

[0008] Preferably, a partition box is installed on one side outer wall of the tank body, each independent space of the partition box is connected to the feed hopper through a connecting pipe, the bottom of the connecting pipe is connected to a water pump, the partition box has multiple independent spaces, and different raw liquids can be stored. The staff only needs to wait until there is no raw liquid in the partition box before adding it.

[0009] Preferably, the driving mechanism includes two sliding rods, which are slidably installed on the top of the tank body, the bottoms of the two sliding rods are respectively connected to the two ends of the top of the hollow ring, and the tops of the two sliding rods are respectively connected to the two ends of the bottom of the top plate, the top plate and the tank body are connected by a spring, and the spring is sleeved on the outside of the sliding rod. Pressing the top plate can make the sliding rod descend, driving the hollow ring to descend, so that the nozzle can comprehensively rinse the inner wall of the tank body and the stirring blades. The top plate descends and squeezes the spring at the same time. When the top plate is released, the top plate is automatically reset by the restoring force of the spring, and the hollow ring can be automatically raised without the need for manual lifting by the staff, thereby reducing the workload.

[0010] Preferably, a rubber layer is provided on the top of the top plate, and the rubber layer is elastic, which can improve the comfort of the staff's palm pressing.

[0011] Preferably, a PLC controller is provided on one side of the tank body, and the controller is convenient for staff to control.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model has a plurality of independent spaces in the partition box through the setting of the feeding mechanism. Different stock liquids are first poured into different spaces. When preparing the liquid, the stock liquid is pumped into the feed hopper through the water pump and the connecting pipe. The staff observes the transparent scale and turns off the water pump after reaching the required capacity. Then, the solution is discharged into the tank through the discharge pipe. The above operation is repeated for each stock liquid to complete the preparation of the liquid. Since the partition box can store more stock liquid, the staff does not need to add the stock liquid every time the liquid is prepared. The stock liquid can be added when there is no stock liquid in the partition box, which reduces the workload of the staff;

[0014] 2. The utility model arranges a hollow ring, a nozzle and a driving mechanism. The nozzle sprays water in the hollow ring onto the inner wall of the tank body and the stirring rod. The staff presses the top plate to lower the sliding rod to drive the hollow ring to lower. During the lowering process, the inner wall and the stirring rod can be fully cleaned, thereby improving the cleaning effect and reducing the influence on the accuracy of the next liquid preparation. The top plate descends to squeeze the spring. After the top plate is released, the restoring force of the spring can make the hollow ring automatically rise and return to its original position. There is no need for the staff to lift it, thereby reducing the workload. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Working principle: Start the water pump 506 to draw the stock liquid in the partition box 504 into the feed hopper 501 through the connecting pipe 505. By observing the transparent scale 502, the required volume can be added to the feed hopper 501.
