Description

Technical Field

[0001] The utility model relates to the technical field of suction devices, in particular to a suction device for a buffer tank. Background Art

[0002] Buffer tanks are mainly used to buffer pressure fluctuations in various systems to make the system work more smoothly. The buffering performance of the buffer tank is mainly achieved by compressing the compressed air in the tank. There are two types of buffer tanks: diaphragm buffer tanks and airbag buffer tanks. They are widely used in water supply equipment and central air conditioning systems. The function of the suction buffer tank is to reduce the unevenness of the suction pipeline flow, reduce inertia loss, and improve the suction performance of the pump. The function of the discharge buffer tank is to reduce the unevenness of the discharge pipeline flow and avoid the generation of excessive flow to meet the needs of the process flow. The suction device for the buffer tank is a device used to absorb materials or liquids in the buffer tank. Its function is to effectively transport materials or liquids from the buffer tank to other locations or processing equipment.

[0003] In actual use, the existing suction device for the buffer tank is not convenient for preventing the material or liquid from flowing back or refluxing into the buffer tank when the suction device stops working, which is easy to cause impurity contamination.

[0004] After searching the existing patent: Buffer tank suction device (publication number: CN201431873Y), the negative pressure generated by the flow of water in the pipe is currently used as the suction power. Water is easily sucked into the reactor, which affects the quality of chemical products and brings safety hazards. The utility model includes a buffer tank with a cavity and a first negative pressure pipe and a second negative pressure pipe connected to the cavity of the buffer tank. The first negative pressure pipe is connected to a vertically arranged water pipe, and the second negative pressure pipe is connected to a reactor. It is characterized in that the first negative pressure pipe is inserted into the cavity of the buffer tank from top to bottom, and the lower end face of the section inserted into the buffer tank is located below the corresponding second negative pressure pipe. The use of this technical solution can prevent water from entering the reactor, improve production safety, and ensure the quality of chemical products.

[0005] Although the above patent prevents water from entering the reactor, improves production safety, and ensures the quality of chemical products, it is not convenient to clear the discharge end, and materials are easily accumulated and blocked at the discharge end, affecting the discharge of materials.

[0006] Therefore, it is necessary to invent a suction device for a buffer tank to solve the above problems. Utility Model Content
