Description

Technical Field

[0001] The utility model relates to the technical field of air compression equipment, in particular to an air pre-filtering device for an air compressor. Background Art

[0002] An air compressor is a device used to compress gas. The structure of an air compressor is similar to that of a water pump. Most air compressors are reciprocating piston type, with rotating blades or rotating screws. Centrifugal compressors are very common. When in use, air compressors need to inhale air from the outside for compression. There is a lot of dust in the atmosphere. If the air in the atmosphere is directly transported to the air compressor for compression, the dust will have a great impact on the operation of the precision parts of the air compressor, especially under heavy dust conditions. The dust in the air will reduce the service life of the air compressor by 30% compared to normal conditions, which is not conducive to production cost savings. Therefore, it is necessary to use an air pre-filter to pre-treat the air inhaled by the air compressor;

[0003] In order to remove dust from the air, the existing air pre-filter device of the air compressor uses a dust filter to filter the air to ensure the cleanliness of the air. However, long-term filtration will cause a lot of dust to adhere to the surface of the filter, which will then clog the filter, resulting in a decrease in the ventilation effect of the filter, thereby reducing the intake compression effect of the compressor. In addition, a self-cleaning structure will increase the cost, which is not economical. At the same time, in order to effectively remove smaller particles of dust in the air, the filtering devices on the market usually wash the introduced air with water by spraying, but this method causes a large amount of water vapor to be contained in the air. When the air compressor sucks it into the body, the components inside the body are easily affected by moisture, thereby damaging the internal components of the compressor. For this reason, we propose an air pre-filter device for an air compressor. Utility Model Content

[0004] The main purpose of the utility model is to provide an air pre-filter device for an air compressor, which can effectively solve the problems in the background technology.

[0006] Preferably, the transmission assembly includes a transmission bevel gear fixedly connected to the end of the second transmission rod, and a driving bevel gear is detachably connected to the position surface of the first transmission rod relative to the transmission bevel gear, and the driving bevel gear is meshingly connected to the transmission bevel gear.

[0007] Preferably, a water storage tank is provided on one side of the filter box, and the bottom end of the water storage tank is interconnected with one side of the bottom end of the filter box, and the inner cavity of the water storage tank is equipped with a water suction pump.

[0008] Preferably, a water pipe is nested at the upper end of the inner cavity of the water storage tank, and one end of the water pipe is interconnected with the water suction pump, and the other end passes through the top of the filter box and extends to the inside of the filter box.

[0009] Preferably, the ends of the water pipes are interconnected with sprinkler heads.

[0010] Preferably, a silica gel water absorption layer is provided in the inner cavity of the filter box and on one side opposite to the spray head.

[0011] Preferably, a base is provided at the bottom end of the filter box.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model is provided with a servo motor, a first transmission rod, a first induced draft fan blade, a second induced draft fan blade, a second transmission rod, an exhaust fan blade and a transmission assembly. The operation of the servo motor drives the first transmission rod to rotate, thereby driving the first induced draft fan blade and the second induced draft fan blade fixed on the surface to rotate at a high speed to introduce outside air into the filter box. During the air induced process, the dust filter inside the first induced draft duct can filter particulate dust in the air. During the filtering process, the brush plate on the surface of the dust filter can rotate with the first transmission rod, thereby cleaning the surface of the dust filter to prevent large particles of dust from clogging the dust filter. After filtering, the driving bevel gear fixed on the surface of the first transmission rod can drive the driving bevel gear meshing with it and the second transmission rod to rotate, thereby driving the exhaust fan to rotate, and the filtered air can be quickly discharged into the air induced cavity of the air compressor, ensuring that the air is clean while effectively improving the ventilation effect. In the whole process, the filter box can achieve all the drives only by one driving motor through the arrangement of the transmission assembly, effectively avoiding the waste of electric energy, reducing the filtering cost, and meeting the economic effect of people.

[0014] 2. The utility model uses a water storage tank and a silica gel water absorption layer. When air is induced, the water absorption pump inside the water storage tank absorbs water and transports it into the sprinkler head through the water pipe, and then sprays it to the inside of the filter box through the sprinkler head, thereby washing the introduced air and effectively removing tiny particles in the air. At the same time, the corresponding waste water will directly flow back into the water storage tank through the through hole at the bottom, thereby realizing the recycling of water and further saving costs. The air after washing will pass through the silica gel water absorption layer during the flow process, and the water-absorbing silica gel arranged in the silica gel water absorption layer absorbs moisture in the air, thereby drying the air after washing, preventing air with too high moisture from entering the air compressor and causing damage to its internal components due to moisture, thereby effectively extending the service life of the air compressor.
