The frame body 1 is a cylindrical hollow frame body welded by aluminum alloy rods. The filter tank 2 is welded inside the frame body 1, so that the frame body 1 surrounds the filter tank 2. The filter tank 2 can be a chemical reaction type gas filter, an adsorption type gas filter, an activated carbon filter or the like. In this embodiment, the filter tank 2 is an adsorption type gas filter. The aluminum alloy is light in weight and high in strength, thereby reducing the weight of the frame body 1, reducing the labor intensity of the staff when carrying, facilitating the staff to carry, and supporting and protecting the filter tank 2.

[0033] Referring to Figure 1 The air inlet 3 is communicated and installed at the air inlet end of the filter tank 2. One air inlet 3 is used for communication with the electric air compressor, and the other air inlet 3 is used for communication with the oil air compressor. Control valves 5 are installed on the two air inlets 3.

[0034] When the use site condition is difficult to power, the staff connects the oil air compressor to one of the air inlets 3 and closes the control valve 5 of the other air inlet 3, so that the compressed gas can be delivered to the filter tank 2 through the air compressor. When there is no oil air compressor at the use site, the staff can also connect the electric air compressor to one of the air inlets 3 and close the control valve 5 of the other air inlet 3, so that the compressed gas can be delivered to the filter tank 2 through the electric air compressor. Thus, the filter can be applied to two types of air compressors under different site conditions, thereby improving the applicability of the filter under different site conditions.

[0035] Referring to Figure 1 The air outlet 4 is communicated and installed at the air outlet end of the filter tank 2. A pressure gauge 9 is communicated and installed on the air outlet 4. The pressure gauge 9 detects the pressure value of the filtered gas flowing out of the filter tank 2, so that the staff can check the air outlet pressure of the filter tank 2. Valves are installed on the air outlet 4, so that the staff can control the opening and closing of the air outlet 4.

[0036] Referring to Figure 1 The distribution pipe 6 is communicated and installed on the air outlet 4. A plurality of air outlet connectors 7 are communicated and installed on the distribution pipe 6. Open and close valves 8 are installed on the plurality of air outlet connectors 7.

[0037] The plurality of air outlet connectors 7 are arranged, so that the staff can connect different numbers of gas supply equipment to the corresponding number of air outlet connectors 7 according to the needs, and close the open and close valves 8 of the air outlet connectors 7 which are not connected to the gas supply equipment, so as to realize the gas supply to the plurality of gas supply equipment at the same time, and improve the applicability of the filter to supply the plurality of gas supply equipment at the same time.

[0038] The implementation principle of the embodiment 1 of the application is as follows: the staff directly carries the frame body 1 to the site of outdoor exploration, emergency rescue, and outdoor construction operation, stably places the frame body 1, connects the air compressor to one of the air inlets 3, closes the control valve 5 on the other air inlet 3, then connects the required gas supply equipment to the gas outlets 7, closes the on-off valve 8 on the gas outlet 7 which is not connected to the required gas supply equipment, starts the air compressor, the air compressor compresses and sends the gas to the filter tank 2, the filtered gas is sent to the required gas supply equipment from the gas outlet 7 after being filtered by the filter tank 2, and the gas filtering under the conditions of outdoor exploration, emergency rescue, and outdoor construction operation is realized. The filter has a small structure and light weight, thereby reducing the components of the filter, reducing the volume and weight of the filter, and improving the portability of the filter under the conditions of outdoor exploration, emergency rescue, and outdoor construction operation.
