A water replenishing liquid level control device for equal volume discharge of multiple solution tanks

Abstract

The invention provides a moisturizing liquid level control device with a plurality of solution cylinders draining liquor averagely. The moisturizing liquid level control device comprises a plurality of insert tubes, a first communicating tube, a detecting tube, a liquid level switch, a second communicating tube and a water receiver. Each insert tube is plugged into a corresponding solution cylinder and the distance between the bottom portion of the insert tube and the bottom portion of the solution cylinder is equal. The plurality of insert tubes are connected through a first end of the first communicating tube, and a second end of the second communicating tube is plugged into the detecting tube which is provided with the liquid level switch. The bottom portion of the detecting tube and the bottom portion of the water receiver are connected through the second communicating tube. Only one liquid level switch is needed by the moisturizing liquid level control device with the plurality of solution cylinders draining liquor averagely and the moisturizing liquid level control device with the plurality of solution cylinders draining liquor averagely can be controlled. The cost is saved and the control is simplified. The moisturizing liquid level control device with the plurality of solution cylinders draining liquor averagely solves problems that the liquid level is unequal caused by the malconformation error of a random trace during the process of the plurality of solution cylinders draining liquor averagely, and alarming signals are produced when a low level firstly appears in one solution cylinder.

Description

Technical field [0001] The invention belongs to the field of liquid level control, and in particular relates to a water replenishment liquid level control device for uniformly discharging a plurality of solution cylinders. Background technique [0002] In the application of drug toxicology and other applications that require equal liquid pumping, the upper liquid filling signal needs to be controlled by the liquid level. Due to the deviation of the set value in the speed of the liquid pumping pump, the liquid level in each solution tank is caused The drop is inconsistent. The use of a liquid level switch for each solution tank will greatly increase the cost. At the same time, the liquid level switch contacts the solution in the solution tank and needs to be cleaned after each use. The liquid level switch will also be corroded by the solution. Summary of the invention [0003] The invention provides a replenishing liquid level control device for evenly discharging a plurality of so...

Problems solved by technology

[0002] In applications such as drug toxicology that require the same amount of liquid pumping, it is necessary to control the upper liquid filling signal by the liquid level. Due to the deviation of the set value of the liquid pumping speed of the liquid pump, the liquid level in each solution tank The drop is not consistent. If each solution tank is equipped with a liquid level switch, the cost will increase significantly. At the same time, the liquid level switch contacts the solution in the solution tank. It needs to be cleaned after each use, and the liquid level switch will be corroded by the solution.
