Description

Technical Field

[0001] This application relates to the field of vacuum pump structures, and more particularly to a vacuum pump mounting structure. Background Technology

[0002] A vacuum pump is a device or equipment that uses mechanical, physical, chemical, or physicochemical methods to evacuate a container and create a vacuum.

[0003] Chinese utility model patent CN208057410U discloses a slide valve vacuum pump, including a pump body, a tank for storing oil on the pump body, an oil-gas separator inside the tank, and an exhaust channel of the pump body connected to the oil-gas separator. The tank is equipped with a partition that divides the tank into an upper chamber and a lower chamber, with a connecting hole in the partition. The upper chamber has an exhaust port and an oil mist filter element built into it, distributed on the connecting hole. The oil-gas separator is located in the lower chamber. This utility model provides a slide valve vacuum pump that integrates the filter element into the tank, allowing oil mist in the gas discharged from the tank's exhaust port to be filtered by the oil mist filter element, preventing atmospheric pollution.

[0004] In actual installation, the housing is divided into an upper chamber and a lower chamber. When installing vacuum pump components, it is necessary to distinguish the chambers first, and then install the components in the upper and lower chambers respectively, which is quite troublesome. Utility Model Content

[0005] To facilitate the installation of vacuum pumps, this application provides a vacuum pump mounting structure.

[0006] This application provides a vacuum pump mounting structure, which adopts the following technical solution:

[0007] A vacuum pump mounting structure includes a housing and an oil mist filter element disposed within the housing. A partition is provided on the housing, dividing the inner cavity of the housing into an exhaust chamber and a mounting chamber located below the exhaust chamber. The oil mist filter element is disposed on the partition and located within the mounting chamber. A vent hole is provided on the partition, connecting the exhaust chamber and the inner cavity of the oil mist filter element. An exhaust port is provided on the housing, connecting to the exhaust chamber, for discharging gas from the exhaust chamber.

[0008] By adopting the above technical solution, a partition is set inside the box, which divides the inner cavity of the box into an exhaust chamber and an installation chamber located below the exhaust chamber. The oil mist filter element is set on the partition. After the gas is filtered by the oil mist filter element, it enters the exhaust chamber through the vent hole. The exhaust chamber is mainly used to contain the filtered gas. Finally, the gas flows out of the box through the exhaust hole. The vacuum pump components only need to be installed in the installation chamber. The space left inside the box is large, and there is no need to install the upper and lower chambers separately, making the vacuum pump structure more convenient to install.

[0009] Optionally, the end of the oil mist filter element away from the vent is closed, and the gas oil mist filter element enters the exhaust chamber through the vent after the sidewall reaches the hollow part of the oil mist filter element.

[0010] By adopting the above technical solution, the gas inside the chamber passes through the side wall of the oil mist filter element to reach the hollow part of the oil mist filter element, without having to enter the hollow part of the oil mist filter element from the bottom, thus providing a wider filtration range.

[0011] Optionally, the partition plate is provided with a plurality of threaded sleeves, and the plurality of threaded sleeves are provided in a one-to-one correspondence with the oil mist filter element, and the oil mist filter element is threadedly connected to the threaded sleeve.

[0012] By adopting the above technical solution, the threaded sleeve facilitates the secure fixing of the oil mist filter element to the bottom of the partition, while also making it convenient to replace and maintain the oil mist filter element.

[0013] Optionally, the height of the exhaust chamber is 3-10cm.

[0014] By adopting the above technical solution, the appropriate height of the exhaust chamber allows for smoother airflow inside the chamber.

[0015] In summary, this application includes at least one of the following beneficial technical effects:

[0016] 1. After the gas is filtered by the oil mist filter element, it enters the cavity through the vent hole and finally flows out of the box through the exhaust hole. The vacuum pump components only need to be installed in the installation cavity. The box has a large space and there is no need to install the upper and lower chambers separately, making the vacuum pump structure more convenient to install.

[0017] 2. The threaded sleeve facilitates the replacement and maintenance of the oil mist filter element;

[0018] 3. An appropriate exhaust chamber height allows for better airflow within the exhaust chamber. Attached Figure Description

[0023] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] This application discloses a vacuum pump mounting structure. (Refer to...) Figure 1 , Figure 2 , Figure 3 The vacuum pump mounting structure includes a housing 1 and an oil mist filter 2 installed inside the housing 1. A partition 3 is fixed on the housing 1, which divides the inner cavity of the housing 1 into an exhaust chamber 4 and a mounting chamber 5 located below the exhaust chamber 4. The exhaust chamber 442 has a height of 3-10cm.

[0025] Reference Figure 1 , Figure 2 , Figure 3 The oil mist filter element 2 is fixed on the partition plate 3 and is located inside the mounting cavity 5. A vent hole 6 is provided on the partition plate 3, connecting the exhaust cavity 4 and the inner cavity of the oil mist filter element 2. An exhaust hole 7 is provided on the housing 1, connecting the exhaust cavity 4 and allowing gas to escape from the exhaust cavity 4. Four oil mist filter elements 2 are fixed, with the ends of the oil mist filter elements 2 furthest from the vent hole 6 sealed. After the gas reaches the hollow part of the oil mist filter element 2, it enters the exhaust cavity 4 through the vent hole 6.

[0026] Reference Figure 1 , Figure 2 , Figure 3 A number of threaded sleeves 8 are fixed on the partition plate 3. The number of threaded sleeves 8 are set one-to-one with the oil mist filter element 2. The outer surface sidewall of the oil mist filter element 2 is provided with threaded lines. The oil mist filter element 2 is threadedly connected to the threaded sleeves 8 through the threaded lines.

[0027] The implementation principle of the vacuum pump installation structure in this application embodiment is as follows: When installing the vacuum pump structure, the oil mist filter element 2 is threaded onto the threaded sleeve 8. After the gas is filtered by the oil mist filter element 2, it enters the exhaust chamber 4 through the vent hole 6. The gas in the exhaust chamber 4 flows out of the housing 1 through the exhaust hole 7. The housing 1 has a large space, and the vacuum pump components only need to be installed in the installation cavity 5, without the need for separate installation of the upper and lower chambers, which improves the installation efficiency and makes the vacuum pump structure installation more convenient.
