[0003] In the related art, the air compressor operates in harsh working environments such as mines, construction sites and stone processing, and the content of dust and other impurities suspended in the air is high; since these dust and impurities can easily enter the interior of the air compressor through the air inlet when the air compressor is operating, once entering the air compressor, the dust and impurities will not only adhere to the key components such as compressor blades and cylinder walls, affecting the normal operation and compression efficiency of the air compressor, but also can cause wear and blockage of internal components, and in severe cases, can even cause the air compressor to malfunction and stop, and thus needs to be improved. CONTENT OF THE UTILITY MODEL

[0004] In order to solve the problem that dust and impurities enter the interior of the air compressor in a harsh environment, the application provides a dust removal device for an air compressor.

[0005] The dust removal device for an air compressor provided by the application adopts the following technical scheme:

[0007] As these dust and impurities in the air compressor when running, easy to enter the air compressor through the air inlet, once into the air compressor, dust and impurities will not only adhere to the compressor blade, cylinder wall, such as key components, affect the normal operation of the air compressor and compression efficiency, but also can cause internal parts wear and blockage, serious even can cause air compressor failure downtime; by adopting the above technical scheme, including the bracket, dust removal box is installed on the bracket, a plurality of air filter cartridge is installed in the dust removal box through the assembly plate, the air inlet pipe and the air outlet pipe are communicated at both sides of the dust removal box respectively;

[0008] When the air compressor needs to be used, the free state of the air is first sucked into the air inlet pipe, and then the sucked air enters the inside of the dust removal box. The air will pass through the air filter cartridge on the assembly plate, which is filled with high-efficiency filter material such as activated carbon, glass fiber, etc. It can capture and remove impurities such as dust particles, oil mist, moisture, etc. in the air. At the same time, the air passes through the air filter cartridge, the spray assembly on the dust removal box will start regularly or as needed to spray an appropriate amount of cleaning liquid (such as water or other environmentally friendly solutions) into the dust removal box. The cleaning liquid reacts with the impurities attached to the surface of the air filter cartridge, making it easier to be removed. After the air filter cartridge and the spray cleaning, the air becomes relatively pure. At this time, it will continue to rise and flow to the top of the dust removal box. The purified air is finally discharged from the air outlet pipe at the top of the dust removal box. The air outlet pipe is connected to the air inlet of the air compressor, ensuring that the pure air can smoothly enter the air compressor for subsequent compression treatment.

[0009] Through the setting of the air filter cartridge and the spray assembly, it can adapt to different working environments, help to achieve efficient dust removal and purification, efficiently capture and remove impurities such as dust particles, oil mist, moisture, etc. in the air, ensure that the dust and impurities in the air are effectively removed, provide relatively pure air to the air compressor, reduce the failure and wear caused by impurity accumulation in the air compressor, and improve the running stability and reliability of the air compressor.

[0015] By adopting the above technical scheme, the spray assembly comprises a water storage barrel, a plurality of spray pipes and a plurality of spray nozzles. When the air passes through the air filter cartridge, the spray assembly on the dust removal box is started periodically or as needed. The cleaning liquid in the water storage barrel is pumped into each spray pipe, and the cleaning liquid flows to the spray nozzles through the spray pipes, ready to be sprayed. The spray nozzles spray fine water mist or water column, which is uniformly sprayed on the surface of the air filter cartridge. The sprayed cleaning liquid reacts with the impurities attached to the surface of the air filter cartridge, causing the impurities to soften, loosen or dissolve. At the same time, the cleaning liquid can also form a water film to help capture and remove dust particles, oil mist and other impurities in the air. Under the action of the cleaning liquid, the impurities attached to the surface of the air filter cartridge are gradually removed and fall to the bottom of the dust removal box along with the cleaning liquid. Through the arrangement of the spray assembly, the dust removal efficiency is improved. Regular cleaning of the air filter cartridge helps to remove impurities attached to its surface, reducing blockage and wear caused by impurities accumulation. This not only prolongs the service life of the air filter cartridge, but also reduces the frequency and cost of replacing the air filter cartridge.

[0020] Optionally, a support plate for mounting the water storage barrel is arranged on the end wall of the dust removal tank, and a plurality of support seats for supporting the water storage barrel are arranged on the support plate.

[0021] By adopting the above technical scheme, the support plate is installed on the end wall of the dust removal tank, and the water storage barrel is installed on the support plate through the support seats; through the arrangement of the support plate and the support seats, the stability of the water storage barrel on the end wall of the dust removal tank is ensured, the possibility of liquid leakage or equipment damage caused by shaking or tilting of the water storage barrel is reduced, and the overall structural stability of the water storage barrel is enhanced.

[0022] Optionally, an air expansion pipe opening is arranged on the dust removal tank, one end of the air expansion pipe opening is in communication with the inside of the dust removal tank, and the other end of the air expansion pipe opening is communicated with the air outlet pipe.
