Detailed Description
Referring to fig. 1 to 6, the present invention provides a filtering and cleaning device 10 for a vacuum system, which includes a housing 100, a hollow filter element 200 and a purging assembly 300. The housing 100 is provided with a pump body interface 101, an equipment interface 102 and a filtrate discharge port 103. The pump body interface 101 is used for connecting with a vacuum pump of a vacuum system. The device interface 102 is used to connect with a device to be evacuated. The filtrate discharge port 103 is used to discharge the filtrate trapped by the hollow filter element 200. The hollow filter element 200 is disposed in the housing 100. The hollow filter element 200 has first and second ends disposed opposite one another along a central axis thereof. The first end is closed, and the second end is communicated with the pump body interface 101. The purge assembly 300 includes a gas blowing member 310, and the gas blowing member 310 is disposed in the inner cavity of the hollow filter cartridge 200.
The filtering and cleaning device 10 provided by the invention can be installed on an air exhaust pipeline of a vacuum system through a pump body interface 101. When air is extracted, the equipment interface 102 is communicated with the equipment to be extracted, and the filtered object outlet 103 is closed. During the air exhaust process, the gas in the device to be exhausted enters the inner cavity of the hollow filter element 200 from the peripheral wall of the hollow filter element 200 and is exhausted by the vacuum system through the pump body interface 101, and the fine particles in the gas are trapped in the micropores of the peripheral wall of the hollow filter element 200. After the air suction process is finished, the equipment interface 102 is closed, the filtered object outlet 103 is opened, and meanwhile, the air blowing element is communicated with an air source. The gas enters the inner cavity of the hollow filter element 200 through the gas blowing member and flows toward the filtrate discharge port 130 through the peripheral wall of the hollow filter element 200. The resulting air flow can carry away the fine particles trapped on the peripheral wall, thereby achieving cleaning of the hollow filter element 200.
The filtering and cleaning device 10 provided by the invention can realize the cleaning of the filter element without being detached from the vacuum system, and the downtime of the vacuum system is reduced.
