Technical Field

[0001] This utility model belongs to the field of air compressor technology, and in particular relates to a dust reduction structure for the heat dissipation vent of a screw air compressor casing. Background Technology

[0002] A screw air compressor is a device that uses the meshing motion of a screw rotor to compress air. It is characterized by high efficiency, stability, and long service life, and has become the mainstream equipment for industrial compressed air. When using it, attention should be paid to daily maintenance in order to reduce operating costs and extend service life.

[0003] The heat dissipation vents of screw air compressors are usually located at the top, forming an air circulation with the air inlets at the bottom or side. After a period of use, the heat dissipation vents of screw air compressors need to be cleaned to prevent impurities in the working environment from accumulating at the vents. In order to protect the heat dissipation vents, a dust reduction structure for the heat dissipation vents of screw air compressor housings has been designed. This structure uses multiple filters to block impurities in the air from entering the heat dissipation vents, thereby protecting the vents and reducing the frequency of cleaning. Utility Model Content

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A dust reduction structure for the heat dissipation vent of a screw air compressor casing, comprising a support frame fixedly connected to the top of a bolt-type air compressor by bolts: a first positioning groove is provided on the front side of the support frame, a filter support frame is slidably connected to the inner cavity of the first positioning groove, a filter is slidably connected to the inner cavity of the filter support frame, a first screw hole is provided on both the left and right sides of the support frame, a second screw hole is provided on both the left and right sides of the filter support frame, and a bolt is threadedly connected to the inner cavity of the first screw hole and the second screw hole.

[0006] Preferably, a second positioning groove is provided on the front side of the support frame, and the second positioning groove is located below the first positioning groove.

[0007] Preferably, the inner cavity of the second positioning groove is slidably connected to a material receiving mesh support frame, and the material receiving mesh support frame is fixedly connected to the support frame by bolts.

[0008] Preferably, a receiving mesh is provided inside the cavity of the receiving mesh support frame, and two limiting grooves are provided at the bottom of the cavity of the first positioning groove.

[0010] Preferably, a pull rod is welded to the front side of the filter support frame.

[0011] The beneficial effects of this utility model are: 1. This utility model checks whether the surface of the filter screen contains a large number of impurities. If so, the filter screen support frame and the filter screen are pulled out of the inner cavity of the first positioning groove together. After replacing the filter screen, the filter screen support frame is reinstalled with the support frame. This can block the impurities in the air from the heat dissipation vent, thereby protecting the heat dissipation vent and reducing the frequency of cleaning the heat dissipation vent. 2.
