Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0037] Such as figure 1 The shown multi-removable mesh filter for vacuum pipelines includes a filter cylinder 1, a filter mesh, a filter end cover 5, a filter blind plate 6, a blind plate gasket 7, and an end cover gasket 8. The fixed distance tube 9, the filter mesh fixing rod 11 and the buffer pad 13.

[0038] The two ends of the filter cylinder 1 are respectively connected to one end of the filter end cover 5 through a hexagon head bolt A12 and a hexagon head nut A14, and the other end of the filter end cover 5 is connected through a hexagon head bolt B15 and a hexagon head nut B16 Connect with blind plate 6 for filter. An end cover gasket 8 is provided at the connection between the filter cylinder 1 and the filter end cover 5, and a blind plate gasket 7 is provided at the connection between the filter end cover 5 and the filter blind plate 6, whic...

Abstract

The invention relates to the technical field of vacuum filtration, and particularly discloses a vacuum pipeline multiple detachable screen filter. The vacuum pipeline multiple detachable screen filtercomprises a filter cylinder, filtering mesh pieces arranged in the filter cylinder, filtering mesh piece fixing rods in series connection with the filtering mesh pieces and distance tubes sleeving the filtering mesh piece fixing rods and defining the distance between every two adjacent filtering mesh pieces. The vacuum pipeline multiple detachable screen filter has the advantages that powder particles are filtered by multiple working-gas-corrosion-resistant metal wire meshes, the size of the filter is small, the effective filtration area is large, the service time is long, the cost is low, the disassembly and assembly are convenient, the radiation dose to on-site operation personnel can be effectively reduced, and the safety is high.

Description

Technical field [0001] The invention belongs to the technical field of vacuum filtration, and specifically relates to a vacuum pipeline multiple detachable mesh filter. Background technique [0002] Filters equipped with sintered nickel filter elements have been used to filter the powder in the vacuum piping system. The effective flow area of ​​the filter is reduced due to the powder deposition. Therefore, the pressure before the filter gradually increases with the increase of running time. When the pressure in front of the filter exceeds the operating limit, the filter must be stopped. In addition, the sintered nickel tube filter has a large volume, a small filtering area, and a short use time. It requires repeated operations such as equipment disassembly and assembly, and a large amount of open work. [0003] Therefore, it is urgent to design a new type of filter to eliminate all the defects of the sintered nickel tube filter. Summary of the invention [0004] The purpose of the...
