Description

Technical Field

[0001] This application relates to the field of vacuum pumps, and more specifically to a vacuum pump cleaning device. Background Technology

[0002] Vacuum pumps are used to create vacuum environments. During use, when gas passes through the vacuum pump, droplets and particles in the gas adhere to the inner wall of the vacuum pump. After long-term use, various indicators of the vacuum pump will change, causing the vacuum level to drop and affecting the working efficiency and quality of the vacuum pump. Therefore, the vacuum pump needs to be cleaned every once in a while.

[0003] In related technologies, cleaning a vacuum pump requires disassembling the pump and then cleaning its internal rotor and other components. The disassembly process is time-consuming, labor-intensive, and very troublesome. Utility Model Content

[0004] To facilitate the cleaning of vacuum pumps, this application provides a vacuum pump cleaning device.

[0005] The vacuum pump cleaning device provided in this application adopts the following technical solution:

[0006] A vacuum pump cleaning device includes a cleaning system for use with a vacuum pump body. The cleaning system includes a cleaning liquid tank and a connecting pipe. The cleaning liquid tank is provided with a liquid inlet pipe. The cleaning liquid tank is connected to the vacuum pump body through the connecting pipe. A flow valve is provided on the connecting pipe. The vacuum pump body is provided with a waste liquid outlet.

[0007] By adopting the above technical solution, and by controlling the flow valve, the cleaning solution stored in the cleaning solution tank can enter the vacuum pump body through the connecting pipe. The cleaning solution treats the impurities adhering to the vacuum pump body, allowing the impurities in the vacuum pump body to be discharged from the pump body with the water flow, thereby conveniently cleaning the vacuum pump body, improving the vacuum degree of the vacuum pump body, and thus improving working efficiency.

[0008] Optionally, a solenoid valve may be provided on the connecting pipe.

[0009] By adopting the above technical solution, a solenoid valve is installed on the connecting pipe. With the flow valve kept open, the flow of cleaning fluid in the connecting pipe can be automatically controlled by the solenoid valve.

[0010] Optionally, an air inlet pipe is provided on the connecting pipe, the air inlet pipe is located at the cleaning liquid inlet of the vacuum pump body, and a switch valve is provided on the air inlet pipe.

[0011] By adopting the above technical solution, after the cleaning fluid finishes cleaning the vacuum pump body, the flow valve is closed. By operating the switch valve, gas is allowed to enter the vacuum pump body through the inlet pipe, keeping the vacuum pump body in the open state. The blown-in gas can accelerate the drying speed of the vacuum pump body.

[0012] Optionally, the washing liquid tank is provided with a liquid outlet pipe, and the liquid outlet pipe is provided with an outlet valve. The liquid outlet pipe is located below the side of the washing liquid tank opposite to the liquid inlet pipe.

[0013] By adopting the above technical solution, an outlet is set below the side of the washing liquid tank away from the inlet. When different cleaning liquids need to be replaced, the liquid flows out from the outlet to clean the washing liquid tank, thereby avoiding mutual interference between different cleaning liquids.

[0014] Optionally, the connecting pipe is detachably connected to the vacuum pump body via a connector.

[0015] By adopting the above technical solution, the connector can connect the connecting pipe to the vacuum pump body, making it convenient for the cleaning fluid to enter the vacuum pump body; and the connector can realize the detachable connection between the connecting pipe and the vacuum pump body, so that when the vacuum pump body fails, the vacuum pump body can be easily disassembled for repair or replacement.

[0016] Optionally, the connecting pipe includes a connecting pipe and an extraction pipe for use with the vacuum pump body. The connecting pipe is connected to the cleaning liquid outlet of the washing liquid tank. The flow valve is installed on the connecting pipe. The cleaning liquid outlet of the connecting pipe is connected to the extraction pipe through a sealing element. The extraction pipe is connected to the vacuum pump body through a connector.

[0017] By adopting the above technical solution, the connecting pipe can be directly connected to the vacuum pump pipe, which facilitates the connection between the washing liquid tank and the vacuum pump body without the need to create a new opening on the vacuum pump body. At the same time, by connecting the vacuum pump pipe to the vacuum pump body, the existing vacuum pump pipe can be reused multiple times.

[0018] Optionally, the sealing element includes a sealing cap, the cleaning fluid outlet end of the connecting pipe is inserted into the sealing cap, the cleaning fluid outlet end of the connecting pipe extends into the suction pipe, and the sealing cap is bonded to the cleaning fluid inlet end of the suction pipe.

[0019] By adopting the above technical solution, the sealing cap seals the gap between the suction pipe and the connecting pipe, which can prevent the cleaning fluid from leaking out and reduce the impact on the environment. In addition, the sealing cap closes the port of the suction pipe, which isolates the inside of the suction pipe from the outside air. When it is necessary to use the vacuum pump body to evacuate the equipment, the flow valve can be closed and the vacuum pump body can be used normally.

[0020] Optionally, a mounting bracket is also included, on which the cleaning solution tank is mounted, and the horizontal height of the cleaning solution outlet of the cleaning solution tank is higher than that of the cleaning solution inlet on the vacuum pump body.

[0021] By adopting the above technical solutions and setting up the mounting bracket, the washing liquid tank can be placed stably, and the relative position of the washing liquid tank and the vacuum pump body can be easily controlled.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By controlling the flow valve, the cleaning solution stored in the cleaning solution tank can enter the vacuum pump body through the connecting pipe. The cleaning solution treats the impurities adhering to the vacuum pump body, allowing the impurities to be discharged from the pump body with the water flow, thereby conveniently cleaning the vacuum pump body, improving the vacuum degree of the vacuum pump body, and thus improving working efficiency.

[0024] 2. After the cleaning fluid has finished cleaning the vacuum pump body, the flow valve is closed. By operating the switch valve, gas is allowed to enter the vacuum pump body through the inlet pipe, keeping the vacuum pump body in the open state. The gas blown in can accelerate the drying speed of the vacuum pump body.

[0025] 3. Connecting the connecting pipe directly to the suction pipe connected to the vacuum pump body facilitates the cleaning of the connection between the device and the vacuum pump body, eliminating the need to create a new opening on the vacuum pump body; at the same time, connecting the suction pipe to the vacuum pump body allows for multiple uses of the existing suction pipe.

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application discloses a vacuum pump cleaning device.

[0033] like Figure 1 As shown, a vacuum pump cleaning device includes a mounting frame 1 and a cleaning system 3. The cleaning system 3 includes a cleaning liquid tank 4 and a connecting pipe 43. The cleaning liquid tank 4 is placed on the mounting frame 1. An inlet pipe 40 is connected to the upper side of one side of the cleaning liquid tank 4. The cleaning liquid inlet end of the connecting pipe 43 is connected to the cleaning liquid tank 4, and the cleaning liquid outlet end of the connecting pipe 43 is connected to the vacuum pump body 2. A flow valve 41 is provided on the connecting pipe 43, and a waste liquid outlet 20 is provided on the lower side of the vacuum pump body 2 away from the cleaning liquid inlet end.

[0034] Open the flow valve 41, and the cleaning liquid in the washing liquid tank 4 flows into the connecting pipe 43. After the cleaning liquid flows out from the connecting pipe 43, it flows into the vacuum pump body 2. The cleaning liquid treats the impurities adhering to the vacuum pump body 2. The impurities in the vacuum pump body 2 flow out from the waste liquid outlet 20 with the water flow, thus cleaning the vacuum pump body 2.

[0035] like Figure 1 and Figure 2 As shown, the connecting pipe 43 includes a connecting pipe 431 and a suction pipe 44. The connecting pipe 431 is connected to the cleaning liquid outlet of the washing liquid tank 4. A flow valve 41 is provided on the connecting pipe 431, and a solenoid valve 42 is provided on the connecting pipe 431. The cleaning liquid outlet of the connecting pipe 431 is connected to the suction pipe 44 through a sealing member 430. The end of the suction pipe 44 away from the sealing member 430 is connected to the vacuum pump body 2 through a connector 440. The sealing member 430 includes a sealing cap 4300, which has an insertion hole 4301. The connecting pipe 431 passes through the insertion hole 4301, and the end of the connecting pipe 431 away from the washing liquid tank 4 extends into the suction pipe 44. The side of the sealing cap 4300 facing the suction pipe 44 is bonded to the suction pipe 44. Keep the flow valve 41 open, operate the solenoid valve 42, and the cleaning liquid in the washing liquid tank 4 flows into the connecting pipe 431, and then into the vacuum pump body 2 through the suction pipe 44, so as to clean the vacuum pump body 2.

[0036] like Figure 3 and Figure 4 As shown, both the cleaning fluid outlet end of the suction pipe 44 and the cleaning fluid inlet end of the vacuum pump body 2 are provided with retaining rings 21. The connector 440 includes two buckles 441. A retaining groove (not shown in the figure) is opened on the inner side of the buckle 441. The buckle 441 is sleeved on the periphery of the retaining ring 21, and the outer wall of the retaining ring 21 abuts against the retaining groove. One end of the two buckles 441 is hinged, and the other end of the two buckles 441 is provided with a limiting hole 4411. A pin 4412 is inserted in the limiting hole 4411, and a nut 4413 is threaded on the pin 4412.

[0037] like Figure 1 and Figure 2 As shown, to accelerate the drying speed of the vacuum pump body 2, an air inlet pipe 5 is connected to the connecting pipe 431. A switch valve 50 is installed on the air inlet pipe 5, which is located at the end of the connecting pipe 431 near the suction pipe 44 and outside the suction pipe 44. After the cleaning fluid has finished cleaning the vacuum pump body 2, the flow valve 41 is closed, the switch valve 50 is operated, and the vacuum pump body 2 is opened. Airflow continuously flows from the air inlet pipe 5 to the waste liquid outlet 20, thus drying the vacuum pump body 2.

[0038] like Figure 1 As shown, to facilitate cleaning of the cleaning solution tank 4 and to avoid interference between different cleaning solutions when changing to different solutions, an outlet pipe 45 is connected to the lower part of the cleaning solution tank 4 away from the inlet pipe 40. An outlet valve 450 is installed on the outlet pipe 45. By closing the flow valve 41 and opening the outlet valve 450, the liquid flows between the inlet pipe 40 and the outlet pipe 45, thus cleaning the cleaning solution tank 4.

[0039] The implementation principle of the vacuum pump cleaning device in Example 1 is as follows: Open the flow valve 41. Under the automatic control of the solenoid valve 42, the cleaning liquid in the washing liquid tank 4 flows into the connecting pipe 431. After flowing out of the connecting pipe 431, the cleaning liquid continues downward through the suction pipe 44 into the vacuum pump body 2. The cleaning liquid treats the impurities adhering to the vacuum pump body 2. The impurities in the vacuum pump body 2 flow out with the water flow from the waste liquid outlet 20, thus cleaning the vacuum pump body 2. After cleaning the vacuum pump body 2, close the flow valve 41 and open the switch valve 50 and the vacuum pump body 2. The airflow flows from the air inlet to the waste liquid outlet 20, which accelerates the drying of the vacuum pump body 2.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
