Description

Technical Field

[0001] This utility model relates to the field of vacuum pump technology, and in particular to a vacuum pump circulating water tank. Background Technology

[0002] Vacuum pumps in blow-fill-seal (BFS) production lines are key equipment, primarily used to maintain the vacuum environment required for the process during blow molding, filling, and sealing. The liquid ring (water ring) vacuum pump used in these pumps is a rough vacuum pump that utilizes a liquid (usually water) as the working medium to form a liquid ring, thereby achieving the pumping function.

[0003] Currently, existing blow-fill-seal equipment vacuum pumps typically operate by directly supplying tap water. While this can meet basic operational needs, it cannot effectively recover and utilize the large amount of water vapor generated during operation, leading to continuous water consumption and serious waste. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that cannot effectively recover and utilize the large amount of water vapor generated during operation, leading to continuous consumption and serious waste of water resources. This invention proposes a vacuum pump circulating water tank.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The vacuum pump circulating water tank includes:

[0007] The base has a liquid ring vacuum pump body fixedly installed on its top. The inlet end of the liquid ring vacuum pump body is fixedly connected to an inlet pipe, and the exhaust end of the liquid ring vacuum pump body is fixedly connected to a water vapor separator.

[0008] The base is equipped with a circulation component, which is used to collect the water vapor separated by the water vapor separator and supply it to the liquid ring vacuum pump body.

[0009] In one possible design, the circulation assembly includes a support frame, on top of which a water tank body is placed. A connecting seat is fixedly connected to the top of the water tank body, and one end of the connecting seat is fixedly connected to a steam condenser pipe. One end of the steam condenser pipe is fixedly connected to the top of a water vapor separator. A water supply pipe is fixedly connected to one side of the water tank body, and one end of the water supply pipe is fixedly connected to one side of a liquid ring vacuum pump body. A manual valve is fixedly installed on the upper part of the water supply pipe near the water tank body.

[0010] In one possible design, a level gauge is fixedly connected to one side of the water tank body.

[0011] In one possible design, the top of the water tank body has an opening, a mounting base is fixedly installed on the top of the water tank body, a hinge frame is hinged to the inner side of the mounting base, and a tank cover that can seal the opening of the water tank body is fixedly installed on one side of the hinge frame.

[0012] In one possible design, the top of the support frame has two symmetrically arranged grooves, and a slider is slidably arranged inside each of the two grooves. A clamping plate is fixedly arranged on the top of each slider. A fixed seat is fixedly arranged at the bottom of the support frame. A bidirectional lead screw is rotatably arranged through one side of the fixed seat. The two ends of the bidirectional lead screw with different threads are respectively threaded to the two sliders. A handwheel is fixedly arranged at one end of the bidirectional lead screw.

[0013] In one possible design, anti-slip pads are fixedly provided on the sides of the two clamping plates that are close to each other.

[0014] In this application, when starting to use, the water tank body is first placed on top of the support frame, and then the handwheel is turned. As the handwheel turns, it drives the double-sided screw to rotate. When the double-sided screw rotates, it drives the two clamping plates to move along the slide groove to the side that is closer to each other until the anti-slip pads on the two clamping plates abut against the two sides of the water tank body, thereby clamping the water tank body and making the water tank body stable on the support frame to prevent vibration or displacement.

[0015] Then connect one end of the steam condenser pipe to the top of the water vapor separator and the other end to the connector on the top of the water tank body. Then connect one end of the water supply pipe to one side of the water tank body and the other end to the water inlet of the liquid ring vacuum pump body. At this time, open the manual valve to ensure that the water supply pipe is unobstructed. Then connect the air inlet pipe to the corresponding equipment and connect the water vapor separator to the corresponding equipment through the condenser head.

[0016] Then, start the liquid ring vacuum pump body. The liquid ring vacuum pump body draws gas through the air inlet pipe to create a negative pressure environment. During the operation of the pump body, the water vapor mixture enters the water vapor separator tank through the exhaust end. The water vapor separator tank separates the gas and water. The gas is discharged, and the water vapor is condensed through the steam condenser pipe. After condensation, the condensate enters the water tank body through the connector. At this time, the water level in the water tank body can be monitored in real time by the level gauge to prevent the water level from being too low or overflowing. The water vapor condenses into liquid water in the water tank body and is stored in the water tank. The condensate in the water tank body flows back to the liquid ring vacuum pump body through the water supply pipe and is used as the liquid ring medium for circulation, thus forming a closed loop circulation system, reducing water waste. The manual valve can adjust the water flow speed to ensure stable operation of the pump body.

[0017] This utility model has the following beneficial effects:

[0018] This invention utilizes a circulation component to condense and recover water vapor generated during the operation of the vacuum pump, allowing it to re-enter the system for reuse. This effectively reduces water waste, improves the economic efficiency and environmental friendliness of the equipment, and reduces reliance on external water supply systems, ensuring the long-term sustainable operation of the equipment.
