To achieve these goals, the technical scheme that the utility model adopts is:
A kind of filter, comprise valve body, whirlwind cover, water tumbler and drainage mechanism, valve body is provided with air inlet and gas outlet, water tumbler is located at the bottom of valve body, drainage mechanism is located at the bottom of water tumbler, water tumbler outer wall is provided with protective cover, whirlwind is sheathed in water tumbler and is fixedly connected with valve body lower end, described whirlwind is arranged with cylindrical sleeve, the outer wall of sleeve is provided with some helical teeth, in sleeve, be equiped with back taper filter core, the lower end of described whirlwind cover is bolted with water fender, water fender is provided with draw-in groove, the lower end of described back taper filter core is arranged in described draw-in groove, the upper end of described back taper filter core and whirlwind cover offset.
Wherein, described back taper filter core comprises the wool felt of outer field metal net mask and internal layer, and the thickness of described wool felt is attenuation gradually from bottom to up.Described water tumbler and described valve body are tightly connected by an O type circle.Described water tumbler is connected with valve body screw thread, and described whirlwind cover is connected with valve body screw thread.
Wherein, described drainage mechanism comprises drain plug, spring and regulating handle, water tumbler bottom is provided with installing hole, drain plug is arranged in installing hole actively, between drain plug and installing hole, be provided with the 2nd O type circle, the upper end of drain plug is provided with back taper plug, the inside of drain plug is provided with drainage channel, the cylinder of drain plug is provided with the osculum of described drainage channel and water tumbler internal communication, described spring is located between described back taper plug and water tumbler, and described regulating handle is bolted in the lower end of drain plug.
Adopt after technique scheme, the advantage that compared to the prior art the utility model had is:
Filter described in the utility model, compressed air enters valve inner from air inlet, after whirlwind cover, producing cyclonic air flow separates the moisture in compressed air, isolated moisture is collected in water tumbler, water in water tumbler is discharged from drainage mechanism, dried compressed air is again after back taper filter element filtering impurity, and last compressed air is discharged from gas outlet.Owing to being equiped with back taper filter core in sleeve, the pressure drop that compressed air produces after back taper filter element filtering impurity is less, and the compressed air pressure loss of discharging from gas outlet is also just less, can save energy consumption, and filter effect is better.And this filter when assembling, first whirlwind cover is spirally connected with valve body, then back taper shape filter core is snapped in the draw-in groove of water fender, then water fender and whirlwind cover are spirally connected, finally water tumbler and valve body are spirally connected and can complete assembling, simple in structure, easy to assembly.
