Description

Technical Field

[0001] The utility model relates to the field of liquid medicine recovery, in particular to a liquid chemical liquid medicine recovery device. Background Art

[0002] In the electronics manufacturing, metal surface treatment and other industries, liquid medicine is an important process medium, and its management and use are directly related to production efficiency and product quality. However, in actual operation, due to human operating errors or equipment aging, the problem of liquid medicine loss often occurs. In past production practices, we have encountered personnel who did not check and confirm the closed state of the pressure relief valve after replacing the filter element. At the same time, the equipment itself lacked the necessary anti-fool measures and the interlocking device design of the equipment was not reasonable, which could not effectively prevent the occurrence of operating errors, resulting in a large amount of process liquid medicine loss. Once a large amount of liquid medicine is lost, it will not only cause huge economic losses and safety hazards to the company, but may also have a serious impact on the stable operation of the production line. In industries involving the use of liquid medicine, how to effectively manage and recycle liquid medicine to prevent its loss due to various reasons has always been an important issue of concern in the industry.

[0003] Therefore, a liquid chemical liquid recovery device is proposed. Utility Model Content

[0005] The technical solution of the utility model is:

[0006] A liquid chemical liquid recovery device comprises a circulation main pipe, a liquid return pipe, a first liquid discharge pipe and a liquid discharge main pipe, one end of the circulation main pipe is connected with the liquid return pipe, the end of the liquid return pipe away from the circulation main pipe is connected with the second liquid discharge pipe, the surface of the second liquid discharge pipe is connected with a circulation pump, the end of the second liquid discharge pipe away from the liquid return pipe is connected with a pneumatic pump, the outer surface of the pneumatic pump is connected with a filter cartridge, the end of the filter cartridge away from the pneumatic pump is connected with a liquid inlet pipe and the surface of the circulation main pipe, by installing a pneumatic pump below the filter cartridge, the liquid medicine in the filter cartridge can be pumped back to the circulation main pipe by the power of the pneumatic pump, the existing pneumatic pump has the advantages of simple structure, convenient maintenance, stable operation and the like, and can ensure the stable recovery of liquid medicine.

[0007] The working principle of the above technical solution is as follows:

[0008] During operation, when the device is used, the circulation main pipe guides the liquid medicine to the pneumatic pump through the return pipe and the second liquid discharge pipe, and then the liquid medicine is pumped back to the filter cartridge for filtration through the pneumatic pump, and then recovered in the circulation main pipe through the liquid inlet pipe. During the process, the second manual valve and the first manual valve are both in a closed state. When the pressure inside the pneumatic pump is too high, the first manual valve is manually opened so that the output end of the pneumatic pump is output toward the third liquid discharge pipe and the pressure relief pipe. During the process, the diaphragm pump reciprocates through the diaphragm to suck the liquid medicine discharged by the pneumatic pump into the pressure relief pipe, and then re-sends the liquid medicine into the circulation main pipe through the pressure relief pipe. When the impure liquid filtered by the filter cartridge needs to be discharged, the second manual valve is manually opened and the first manual valve is closed at the same time, so that the impure liquid can be discharged through the first liquid discharge pipe to the liquid discharge main pipe.

[0009] In a further technical solution, the outer surface of the pneumatic pump is further connected to a third liquid discharge pipe, one end of the third liquid discharge pipe away from the pneumatic pump is connected to a pressure relief pipe, and the top end of the pressure relief pipe is connected to the circulation main pipe.

[0010] By setting the top of the pressure relief pipe to be connected to the circulating main pipe, the original pressure relief pipe can be modified to be directly connected to the circulating main pipe. When the internal pressure of the pneumatic pump is too high, the pressure relief pipe is automatically opened by the diaphragm pump to release excess liquid into the circulating main pipe to avoid liquid loss.

[0011] In a further technical solution, a diaphragm pump is fixedly connected to the surface of the third liquid discharge pipe.

[0012] By arranging a diaphragm pump, the volume of the third liquid discharge pipe can be changed through the reciprocating agitation of the diaphragm sheet inside the diaphragm pump, so as to suck in the medicine liquid and send it into the pressure relief pipe.

[0013] In a further technical solution, a first liquid discharge pipe is connected between the outer surface of the third liquid discharge pipe and the main liquid discharge pipe, and a second manual valve is connected to the surface of the first liquid discharge pipe.

[0014] When the second manual valve is opened, the waste liquid filtered in the filter cartridge can be discharged downward through the drain pipe.

[0015] In a further technical solution, the outer surface of the third liquid discharge pipe is connected to a first manual valve.

[0016] By providing the first manual valve, the first manual valve and the second manual valve can be used in conjunction with each other, so that pump bodies are provided at both ends of the third liquid discharge pipe, which facilitates control to allow liquid discharge.

[0017] In a further technical solution, the first manual valve and the second manual valve are normally in a closed state.

[0018] Prevent the loss of medicine.

[0020] 1. By installing a pneumatic pump under the filter cartridge, the liquid medicine in the filter cartridge can be pumped back to the circulation main pipe by the power of the pneumatic pump. The existing pneumatic pump has the advantages of simple structure, convenient maintenance, stable operation, etc., which can ensure the stable recovery of the liquid medicine;

[0021] 2. By setting the top of the pressure relief pipe to be connected to the circulation main pipe, the original pressure relief pipe can be modified to be directly connected to the circulation main pipe. When the internal pressure of the pneumatic pump is too high, the pressure relief pipe is automatically opened through the diaphragm pump to release the excess liquid into the circulation main pipe to avoid liquid loss;

[0022] 3. A first manual valve and a second manual valve are respectively provided at both ends of the third liquid discharge pipe, which can be manually controlled according to production needs. Under normal circumstances, liquid needs to be discharged when replacing the filter element or meeting other production needs. The corresponding first manual valve and the second manual valve need to be manually opened to allow liquid to be discharged. By adding the first manual valve and the second manual valve, the discharge of the liquid can be controlled and the replacement of the filter element is convenient. BRIEF DESCRIPTION OF THE DRAWINGS
