To achieve these goals, this utility model is to realize by the following technical solutions: a kind of corrosion-resistant explosion-proof air filter, including the first drainage screen, second drainage screen, polyurethane integument, seal lid and housing, the crown center of described housing is provided with air inlet, top in described housing is provided with fixed groove, the surrounding of described first drainage screen is provided with the second drainage screen, and first be provided with polyurethane filter element packed layer between drainage screen and the second drainage screen, the upper end of described second drainage screen is arranged on fixed groove, described sealing covers the bottom being fixed in housing by support bar, and sealing lid is arranged on the bottom of the second drainage screen, the surrounding of described second drainage screen is provided with polyurethane integument, it is provided with gas outlet in the middle of the bottom of described housing。The inwall of described housing is provided with abrasion-proof ceramic coat；The outer wall of described housing is provided with teflon coatings；Described teflon coatings is outside equipped with TPU layer, and the thickness of described abrasion-proof ceramic coat is between 2～3mm, and the thickness of described teflon coatings is between 5～6mm, and the thickness of described TPU layer is 2mm。
Preferably, described housing is cylindrical hollow configuration。
Preferably, the contact position at the top in described second drainage screen and housing is provided with the first rubber washer, and is provided with the second rubber washer between the bottom of the second drainage screen and sealing lid。
Preferably, described first rubber washer and the second rubber washer are cirque structure。
TPU (Thermoplasticpolyurethanes), have another name called Polyurethane Thermoplastic Elastomer, it is broadly divided into polyester-type and polyether-type, its hardness range is wide, mechanical strength is high, and bearing capacity, impact resistance, damping property are prominent, and tolerance to cold is excellent, good processability, oil resistant, mycete water-fast, resistance to。
The beneficial effects of the utility model:
This utility model arranges abrasion-proof ceramic coat by the inwall at housing so that anti-corrosion capability and the anti-cavitation polishing machine of cleaner are greatly improved, the service life of extension device；The teflon coatings arranged has explosion-proof, it is possible to reduce cleaner because of excessive fluid pressure, and causes the danger that cylinder bursts；By arranging TPU layer, increase mechanical strength and the bearing capacity of equipment；This utility model is simple and reasonable, economical and practical, easy to use, by the first drainage screen, polyurethane filter element packed layer, the second drainage screen and polyurethane integument with the use of, substantially increase its filter effect, can effectively reduce the damage of electromotor。
