Description
Technical field
The utility model relates to the functional parts in the single-screw extruder equipment.
Technical background
Existing peg type filter net device is mainly face of cylinder cooperation, end face compresses sealing, opens pin by leading screw.It is more that this filter net device weak point is that end face compresses the screw number of usefulness, and it is longer to change the screen pack required time; After long-time the use, end face seal place has the thickener phenomenon; Secondly the leading screw holder structure is complicated, and has taken the many valuable area in plastic extruder workplace.
Summary of the invention
The purpose of this utility model be to provide a kind of service time length, good seal performance, open pin easily, short conical surface seal filter net device of draping time.
Conical surface seal filter net device described in the utility model is made up of filter and pin opener, filter mainly contains conical plug, body, feather key, gland, conical plug is positioned at the body middle part, connect by feather key between the two, the conical plug middle part is a cavity, some apertures are arranged on the wall, wall is provided with filter screen outward, and body is provided with charging aperture and discharging opening, and charging aperture and discharging opening are communicated with described cavity by aperture and passage respectively, gland is positioned at the body left end, with body for being threaded, pin opener opens pin nut, handle, screw rod, handwheel, handwheel are contained in the screw rod end, screw rod and opening between the pin nut to being threaded opens pin nut and fixedlys connected with handle.
Described conical plug outer wall left side section is a taper seat, and right section is a cylinder barrel shaped, and described aperture can be driveed on the face of cylinder; Conical plug is provided with the shunting pin by charging aperture one end, and shunting pin and conical plug are for being threaded; The conical plug left side is provided with tapped blind hole.
Structure described in the utility model has good sealing, and it is convenient to change screen pack, has reduced the draping time, has improved operating efficiency.
Description of drawings
Fig. 1 is a cutaway view of the present utility model.
Among the figure: 1-conical plug, 2-body, 3-shunting pin, 4-charging aperture, 5-filter screen, 6-feather key, 7-gland, 8-open pin nut, 9-handle, 10-screw rod, 11-handwheel, 12-discharging opening.
The specific embodiment
Fig. 1 can be used as embodiment of the present utility model.
The filter of present embodiment mainly contains conical plug 1, body 2, shunting pin 3, feather key 6, gland 7, conical plug 1 is positioned at body 2 middle parts, connects by feather key 6 between the two, and conical plug 1 middle part is a cavity, the left side section of outer wall is a taper seat, right section is a cylinder barrel shaped, and described aperture is driveed on the face of cylinder, and wall is provided with filter screen outward, feather key 6 is housed on the taper seat of conical plug 1, relative position at body 2 has keyway, and connects with securing member, and conical plug 1 inserts body 2 by feather key 6.Body is provided with charging aperture 4 and discharging opening 12, and charging aperture 4 and discharging opening 12 are communicated with described cavity by aperture and passage respectively, and gland 7 is positioned at body 2 left ends, fixedlys connected with body 2, and body has tapped blind hole on 2 left sides.Pin opener opens pin nut 8, handle 9, screw rod 10, handwheel 11, and handwheel is contained in the screw rod end, and screw rod and opening between the pin nut to being threaded opens pin nut and fixedlys connected with handle.
When filter is used, to connect and be surrounded by the conical plug insertion body (by the feather key location) of screen pack with the shunting pin, this moment, taper seat was fitted substantially, screw in gland again, gland pushes conical plug in the screw-in process, the taper seat of conical plug and body is reached after the applying fully, can operate as normal.Plastic melt is flowed into by charging aperture, and the mesh of process filter screen and conical plug enters the inner chamber of conical plug, and the discharging opening by the conical plug top flows out again, finishes filtration treatment.When needs are changed screen pack (equipment is in stopped status), earlier gland to be turned on, the tapped blind hole of conical plug left end exposes, and the threaded portion of pin opener screw front end is screwed into the screw of conical plug, rotates the handle of pin opener then, makes to open pin nut and advance; When opening pin nut and prop up body, opening pin nut will not readvance; At this moment rotary handle again, screw thread will drive screw rod and shrink back, and applies less power like this and just can easily conical plug be extracted from body on handle.With the keyway in the feather key aligning body of conical plug, withdraw from pin opener when assembling again, gland is screwed, thereby finish the overall process of changing screen pack.Time saving and energy saving, shortened the draping time greatly.
