Description
Technical field
The utility model relates to extruder technology field, two long-acting draping safety device of filter core on especially a kind of extruder.
Background technology
After on extruder, two filter core leaches impurity in the course of the work, pressure in strainer body is caused to raise, often to dismantle the filter screen that plug more renews, existing domestic and international various pairs of filter core device of long-efficiency changing of wires, in the course of work of long-acting draping, the refuse that the molten resin extruded by extruder filters out needs to change filter screen, screw on filter screen core plug is often dismantled, filter screen produces again the barrier pressure up to 20Mpa in the course of the work, on the plug at strainer body two ends, soket head cap screw can slide tooth after a long time use, plug is caused to spray, the people around injury and equipment.
Utility model content
The technical problems to be solved in the utility model is: in order to overcome strainer body two ends plug on soket head cap screw can slide tooth after a long time use, plug is caused to spray, injury people around and the problem of equipment, now provide two long-acting draping safety device of filter core on a kind of extruder.
The utility model solves the technical scheme that its technical problem adopts: two long-acting draping safety device of filter core on a kind of extruder, comprise strainer body, parallel in described strainer body two filter cores are installed, two end faces of described strainer body are positioned at filter shaft, to the position at place, circular plug are all installed, described plug is connected by soket head cap screw with strainer body, the upper surface of described strainer body is provided with filter screen case, it is characterized in that: the top of described filter screen case is provided with safety protection frame, the two ends of described safety protection frame all have plate washer, described plate washer lays respectively at plug both sides.
Conveniently install further, described plate washer inwall all has a projection, the longitudinal section of described projection is isosceles trapezoid, and two hypotenuses of described isosceles trapezoid are tangent with two plugs of homonymy respectively, plug needs often dismounting, so safety protection frame adopts two direct framves of projection on plug.
For the ease of using further, described safety protection frame is provided with handle.
In order to reinforce plate washer further, the outer wall of described plate washer is provided with some reinforcements.
Preferably, the material of described plate washer is carbon steel.
The beneficial effects of the utility model are: on a kind of extruder of the present utility model, two long-acting draping safety device of filter core can prevent plug from spraying effectively, has structure simple, easy to use, the advantage that security performance is high.
