Technical Field

[0001] The utility model belongs to the technical field of gas compressors, and in particular relates to a gas compressor filtering mechanism. Background Art

[0002] The gas compressor filter mechanism is a key component to ensure the normal operation and extended service life of the compressor. It is mainly responsible for filtering and purifying the gas entering the compressor to remove impurities.

[0003] Common gas compressor filter mechanisms have some disadvantages when used, such as: the above device can only filter air of one specification, large particles of impurities in the air can easily clog the filter, affecting the filtering effect, and small particles of impurities filtered out will be adsorbed on the filter, which needs to be cleaned. The filter is generally fixed by bolts, and the bolts may be stripped after long-term use, making it difficult to disassemble and wasting time. In view of this, we propose a gas compressor filter mechanism. Utility Model Content

[0004] The purpose of the utility model is to provide a gas compressor filtering mechanism to solve the problems raised in the above background technology.

[0005] In view of this, the utility model provides a gas compressor filtering mechanism, comprising:

[0006] A fixed shell, a collection box is inserted and installed in the fixed shell, an air inlet pipe is fixedly installed on one side of the fixed shell and above the collection box, the air inlet pipe is communicated with the inner cavity of the fixed shell, a rectangular frame 1 is fixedly installed in the fixed shell and above the air inlet pipe, a filter screen 1 is fixedly installed in the rectangular frame 1, and two rectangular blocks are arranged in the fixed shell and above the filter screen 1;

[0007] A driving assembly, which is located in the fixed shell and is used to drive the two rectangular blocks to slide;

[0008] A connecting pipe, the connecting pipe is fixedly installed on the other side of the fixed shell, and the connecting pipe is located above the first filter screen, an air outlet pipe is fixedly installed on one side of the connecting pipe, a second rectangular frame is plugged and installed in the connecting pipe, and a second filter screen is fixedly installed in the second rectangular frame;

[0009] The fixing component is located in the second rectangular frame and is used to fix the second rectangular frame to the connecting pipe.

[0010] In the technical solution, when the gas compressor is in use, the outside air will enter the fixed shell from the air inlet pipe, and then the large particles of impurities will be filtered by the filter mesh 1 and stay at the bottom of the filter mesh 1 or fall into the collection box below and be collected, and the filtered air will enter the connecting pipe through the filter mesh 1, and then the small particles of impurities will be filtered by the filter mesh 2 and adsorbed on one side of the filter mesh 2, and finally the clean air will enter the gas compressor through the air outlet pipe, so that the air in the gas compressor will not contain impurities;

[0011] When the filter screen 1 is filtering, the driving assembly can drive the two rectangular blocks to slide downward, and the two rectangular blocks will knock the top of the filter screen 1, so that the large particles of impurities at the bottom of the filter screen 1 fall into the collection box and are collected, so that the filter screen 1 will not be blocked;

[0012] When filter 2 needs to be cleaned, through the set fixing component, personnel can pull rectangular frame 2 and drive filter 2 out of the connecting tube to clean filter 2. After cleaning filter 2, personnel insert rectangular frame 2 into the connecting tube and fix the position of rectangular frame 2 through the set fixing component.

[0016] In the technical solution, when the filter screen is filtering, the motor is started, the motor drives the half gear to rotate, the half gear drives the rack meshing with it to slide upward, the rack drives the sliding block and the rectangular block to slide upward, and at the same time, a number of springs are squeezed and contracted. When the half gear is no longer meshed with the rack, under the action of the rebound force of the several springs, the sliding block slides downward and drives the two rectangular blocks to slide downward. The two rectangular blocks will knock on the top of the filter screen, so that the large particles of impurities at the bottom of the filter screen fall into the collection box and are collected, so that the filter screen will not be blocked.

[0017] In the above technical solution, further, the fixing assembly includes:

[0019] In the technical solution, when the filter screen 2 needs to be cleaned, the personnel first pinch the two pressing blocks, and the two pressing blocks respectively drive the two sliding bars to slide and approach each other, and the two sliding bars drive the corresponding limit blocks to slide and approach each other, and at the same time, the plurality of springs 2 are squeezed and contracted. When the plurality of limit blocks are separated from the connecting tube, the personnel can pull the rectangular frame 2 and drive the filter screen 2 to be taken out of the connecting tube, and the filter screen 2 can be cleaned;

[0020] After the filter screen 2 is cleaned, the staff inserts the rectangular frame 2 into the connecting tube, and then releases the two pressing blocks. Under the action of the rebound force of the springs 2, the two sliding bars slide and move away from each other, and the two sliding bars drive the corresponding limit blocks to slide and move away from each other. Then, the limit blocks are inserted into the connecting tube to fix the position of the rectangular frame 2.

[0022] In this technical solution, it is ensured that dust in the air inlet duct will move toward the fixed shell.

[0023] In the above technical solution, further, a rubber pad is fixedly installed on the bottom of the rectangular block.
