Abstract
The utility model discloses a pneumatic diaphragm pump air inlet filter device, comprising a cylindrical filter device casing body and a top cover, wherein an air inlet and a drain outlet are formed in the side wall of the cylindrical filter device casing body; the middle of a bottom plate of the cylindrical filter device casing body is sunken down; the air inlet is arranged in the middle of the side wall; a magnet is arranged on the inner side of the side wall; the middle of the magnet corresponds to the air inlet; the drain outlet is arranged at the bottom; the drain outlet corresponds to the most concaved place of the bottom plate; the middle of the top cover is provided with an air outlet; the cylindrical filter device casing body and the top cover are fixedly connected by bolts; and a filter core made of an austenitic stainless steel material is fixedly installed on the top cover. The filter core is made of the austenitic stainless steel material and is firm and strong in weather resistance, thereby avoiding the problem that the filter core which is made of other materials is magnetized by the magnet to result in the reduction of the filter effect; and the middle of the bottom plate is sunken down, which is convenient for discharge of water and other impurities.
Description
Technical field
The utility model relates to air filter technical field, is specifically related to a kind of pneumatic diaphragm pump air inlet filter.
Background technology
In gas in air feed process, contain moisture and impurity, in impurity, also comprise part heavy metal, if not to its process can acceleration equipment wearing and tearing, shorten the physical life of pneumatic diaphragm pump.
Summary of the invention
The utility model, for prior art weak point, provides a kind of new pneumatic diaphragm pump air inlet filter.
The scheme that the utility model solves prior art problem is: a kind of pneumatic diaphragm pump air inlet filter, it is characterized in that: comprise cylindrical filter housing, top cover, the sidewall of described cylindrical filter housing is provided with air inlet, sewage draining exit, the base plate middle part of cylindrical filter housing is to recessed, air inlet is located at sidewall middle part, inside sidewalls is provided with magnet, the corresponding air inlet in magnet middle part, sewage draining exit is located at bottom, the recess of the corresponding base plate of sewage draining exit, top cover middle part is provided with air outlet, between cylindrical filter housing and top cover, adopt bolt to be fixedly connected with, the filter core that on top cover, fixed installation is made by austenitic stainless steel material.
As such scheme preferably, described filter core comprises two-layer 80-100 object filter screen.
Compared with prior art, in the utility model, filter core adopts austenitic stainless steel material to make, firm on the one hand, weatherability is strong, also can prevent from the other hand adopting other materials to cause filter core by magnet magnetization and filter effect reduces, the discharge of water and other impurity, to recessed, is convenient in base plate middle part.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, cylindrical filter housing; 2, air inlet; 3, filter core; 4, top cover; 5, sewage draining exit; 6, magnet; 7, air outlet.
