Description

Technical Field

[0001] The present application relates to the technical field of gas compressors, and in particular to a dust-barrier gas compressor intake component. Background Art

[0002] Gas compressors require large quantities of air or other gases to operate. Air often contains dust and impurities. If these impurities enter the compressor, they can not only increase wear and tear on the compressor, reduce compression efficiency, but can also cause failures, increasing maintenance complexity and costs. Therefore, conventional filters are often installed at the compressor's air inlet to block dust and impurities.

[0003] While the filter effectively blocks dust, over time, dust accumulates on the filter, affecting the efficiency of air passing through it and, in turn, reducing air intake efficiency. This requires regular removal, cleaning, or replacement of the filter to ensure proper operation of the compressor. However, this regular maintenance not only increases labor costs but, in some cases, may also affect the continuous operation of the compressor. Utility Model Content

[0008] The pipeline switching component 2 includes a switching valve 2 connected to the filter rear cavity, and a plurality of connecting pipes 2 are provided on the switching valve 2.

[0014] By cooperating with the filter element, pipeline switching component 1 and pipeline switching component 2, the state of the switching valve can be flexibly controlled to realize automatic switching between normal operation and reverse flushing, thereby improving the maintenance convenience and working efficiency of the equipment. During normal operation, the external gas enters the conduction chamber after being filtered by the pre-filter chamber and the filter element, and is finally supplied to the gas compressor.

[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] The present application discloses a dust-blocking gas compressor intake component. Figure 1-3 , a dust-blocking gas compressor intake component, comprising a housing 1, wherein the housing 1 comprises a lower housing 101 and an upper housing 102;

[0021] The lower shell 101 includes a lower cover 1011, a sealing support plate 1012 is installed on the inner side of the lower cover 1011, and a drain valve 5 is installed on the bottom of the lower cover 1011. The upper shell 102 includes an upper cover 1021 that is detachably mounted on the lower cover 1011. Threaded holes are provided on the lower cover 1011 and the upper cover 1021, and bolts are installed in the threaded holes. The upper cover 1021 and the lower cover 1011 are locked by the bolts. A embedding groove is opened on the top, and the lower cover shell 1011 is inserted into the embedding groove to ensure the sealing of the connection. A sealing strip is installed in the embedding groove to further improve the sealing. A sealing plate 1022 is installed on the upper cover shell 1021 to separate the upper shell 102 into an equipment room and a filter room. A partition 1023 is installed on the sealing plate 1022 to divide the equipment room into a maintenance room and a conduction room. Among them, an inspection cover 1024 is installed on the maintenance room to facilitate the staff to inspect the internal components.

[0022] Reference Figure 2 A filter element 2 is installed between the sealing support plate 1012 and the blocking plate 1022. The filter element 2 divides the interior of the housing 1 into a pre-filtration chamber and a post-filtration chamber. A sealing structure is added at the connection between the filter element 2 and the sealing support plate 1012 and the blocking plate 1022 to prevent dust from leaking from the side. The conduction chamber is connected to the post-filtration chamber.

[0023] Reference Figure 3 , a pipeline switching component 1 3 and a pipeline switching component 2 4 are installed on the upper side of the filter element 2 on the upper shell 102. The pipeline switching component 1 3 includes a switching valve 1 301 connected to the pre-filter chamber. Two connecting pipes 1 302 are installed on the switching valve 1 301. The ends of the two connecting pipes 1 302 pass through the upper cover shell 1021 and reach the outside of the upper cover shell 1021. The end of one connecting pipe 1 302 is connected to the air inlet end of the external bag filter, and the end of the other connecting pipe 1 302 is connected to the external gas supply equipment. The backwash gas can be collected through the bag filter to facilitate subsequent unified processing.

[0024] Reference Figure 3The pipeline switching component 24 includes a switching valve 2401 connected to the conduction chamber. Two connecting pipes 2402 are installed on the switching valve 2401. The ends of the two connecting pipes 2402 pass through the upper cover 1021 and reach the outside of the upper cover 1021. The end of one connecting pipe 2402 is connected to the air inlet end of the gas compressor, and the end of the other connecting pipe 2402 is connected to the air outlet end of the external high-pressure gas supply equipment. The switching valve 2401 and the switching valve 1 301 can both use pneumatic switching valves, electromagnetic switching valves, etc. as needed. The state switching of the switching valve 1 301 and the switching valve 2 401 is controlled by the operation control system on the gas compressor to realize The state is switched between normal operation and back flushing. During normal operation, the switching valve 1 301 is connected to the external gas supply equipment, and the switching valve 2 401 is connected to the air inlet pipe of the gas compressor. The gas entering the gas compressor is filtered through the filter element 2. When cleaning is required, the switching valve 1 301 and the switching valve 2 401 are controlled to switch the air path conduction direction. The switching valve 1 301 is connected to the air inlet end of the external bag filter, and the switching valve 2 401 is connected to the external high-pressure gas supply equipment. The high-pressure gas supply equipment is used to supply air to the housing 1, and the filter element 2 is back flushed, and the dust and impurities are blown back into the bag filter through the switching valve 1 301.

[0025] The implementation principle of a dust-blocking gas compressor intake component in an embodiment of the present application is as follows:

[0026] During normal operation, external air enters the pre-filter chamber 2 through the switching valve 1 301 of the pipeline switching assembly 1 3. Dust is then filtered through the filter element 2, and finally, the air is directed to the air inlet of the gas compressor through the switching valve 2 401 of the pipeline switching assembly 2 4, entering the gas compressor.

[0027] When filter element 2 needs to be cleaned, the air flow direction is reversed by controlling the switching valves 1 301 and 2 401. At this point, switching valve 1 301 is connected to the bag filter's air inlet, while switching valve 2 401 is connected to an external high-pressure gas supply. High-pressure gas flows back toward filter element 2, flushing it back and removing accumulated dust and impurities. During the cleaning process, dust enters the bag filter through switching valve 1 301.
