DETAILED DESCRIPTION

[0019] The present invention is further described below with reference to the accompanying drawings and embodiments, but is not intended to be limiting of the present invention.

[0020] See also Figure 1 A simple rust-proof compressed air filter comprises: a filter housing 100, a filter partition 101, a filter element fixing frame 210, a filter element 220, a filter anti-corrosion mechanism 230, and a filter element sealing gasket 240. The filter housing 100 is provided with a filter inlet 310, a filter outlet 320, and a filter drain outlet 330.

[0021] like Figure 2 As shown, the filter partition 101 has a filter element mounting seat 1 102.1 and a filter element mounting seat 2 102.2.

[0022] like Figure 3 As shown, the filter element fixing frame 210 is provided with a filter element fixing rod bracket 210.1, a filter element pressing plate 210.2, and a filter element fixing rod 210.3, and the filter element pressing plate 210.2 is provided with a filter element pressing plate bolt hole 210.2.1.

[0023] like Figure 4 As shown, the filter element mounting seat 102 is provided with 102-1-filter element mounting inner hole, 102-2-filter element fixing screw hole, 102-3-filter element boss mounting seat, and 102-4-filter element positioning step.

[0024] like Figure 5 As shown, the filter anti-rust mechanism 230 is provided with an anode mounting hole 230.1.

[0025] As shown in the figure, the filter partition 101 is welded to the filter housing 100 on all sides to prevent leakage, and the filter housing 100 is divided into two parts. The filter element mounting seat 102 includes a filter element mounting seat 1 102.1 and a filter element mounting seat 2 102.2. The filter element positioning step 102-4 and the filter element boss mounting seat 102-3 of the filter element mounting seat 102 are welded and fixed to the filter partition 101. The filter element 220 is installed in the filter element mounting inner hole 102-1, and the filter element fixing frame 210 is installed in the filter element 220. The filter element fixing frame 210 includes a filter element fixing rod bracket 210.1, a filter element pressing plate 210.2, a filter element pressing plate bolt hole 210.2.1, and a filter element fixing rod 210.3. The filter element fixing rod 210.3 passes through the filter element 220 and the anode mounting hole 230.1 to fix the filter anti-corrosion mechanism 230. A filter element sealing gasket 240 is padded under the filter element pressing plate 210.2 of the filter element fixing frame 210 and is fixed to the filter element fixing screw hole 102-2 through the filter element pressing plate bolt hole 210.2.1 with a filter element mounting metal bolt 103.

[0026] The filter anti-corrosion mechanism 230 is a sacrificial anode, which is a magnesium anode, a zinc anode or an aluminum anode, and is circular, square or polygonal in shape, and is installed below the filter element 220 through the filter element fixing frame 210.

[0027] In summary, the connection or contact between the filter anti-corrosion mechanism 230, i.e., the sacrificial anode and the filter housing 100, is a metal connection, forming a galvanic cell.

[0028] When in use, unfiltered compressed air enters the filter housing 100 from the filter inlet 310, is filtered by the filter element 220, and clean gas is discharged from the filter outlet 320. The moisture and impurities filtered out by the filter element 220 flow from the surface of the filter element 220 through the filter anti-rust mechanism 230, gather at the bottom, and are discharged from the filter drain port 330.

[0029] In the above process, the filter housing 100 is a steel structure, and the filter anti-corrosion mechanism 230, i.e., the sacrificial anode, is a magnesium anode, a zinc anode or an aluminum anode, which is a metal material with a relatively negative potential. When it is connected to the protected filter housing 100 and contacts with moisture in the compressed air, it preferentially dissociates itself, thereby inhibiting the corrosion of the filter housing 100. By regularly replacing the filter element 220, checking the corrosion condition of the filter anti-corrosion mechanism 230, and replacing it in time according to the specific situation, the service life of the filter can be guaranteed and the normal operation of the equipment can be guaranteed.
