Portion is located at the rear end of discharge screw rod 8, and the left and right ends removable seal of filter body 1 is connected with sealing hatch door 12, the suction
It is provided with material sucking port 13 on the side that block 9 contacts with screen pack 7, the row of being provided with side of the suction block 9 away from screen pack 7
Material mouth 14, discharge gate 14 are connected with the outer wall gap location of discharge screw rod 8, and the discharge screw rod 8 is the cored screw of inner hollow,
The endoporus one end of discharge screw rod 8 is connected with discharge gate 14, and the other end is connected with trash discharge runner 11.
As shown in Figure 5, it is preferred that the middle part of suction block 9 offers the mounting hole 15 of connection discharge screw rod 8, the suction
Material mouth 13 is the dirty material holding tank 16 arranged along its length on the front of suction block 9 of the both sides of mounting hole 15, and the dirt is expected
Holding tank 16 is connected with the discharge gate 14 at the back side of suction block 9.
As shown in Figure 6 and Figure 7, it is preferred that suction screw rod 17, institute are installed in the dirty material holding tank 16 of the suction block 9
Suction screw rod 17 is stated to be arranged vertically and between the two by bevel gear engaged transmission with discharge screw rod 8.Suction screw rod 17 is by discharge
Impure dirty material in dirty material holding tank 16 is quickly transported in discharge screw rod 8 by screw rod by bevel gear Synchronous Transmission
In hole or outer wall gap.
Preferably, the front of suction block 9 caves inward along its length positioned at the position of the dirty downside of material holding tank 16, recessed
Sunken place offers scraping blade 18, and the hole flowed through for material is offered in dirt material holding tank 16 side wall adjacent with scraping blade 18
Road, the front end face of scraping blade 18 are concordant with the front of suction block 9.
Preferably, the front of suction block 9 is provided with multiple suction holes 19 positioned at the position of the dirty downside of material holding tank 16, inhales
The material bottom of hole 19 is connected with dirt material holding tank 16.
During actual selection, it may be selected to set scraping blade 18 or suction hole at the dirty material holding tank 16 downside position in left side
19, at the dirty material holding tank 16 downside position on right side, scraping blade 18 or suction hole 19 are set, the left and right sides is applied in combination, that
This does not have an impact.
As shown in Figure 8, it is preferred that the side end of suction block 9 one offers the mounting hole 15 of connection discharge screw rod 8, institute
It is the dirty material holding tank 16 arranged along its length on the front of suction block 9 of the side of mounting hole 15 to state material sucking port 13, described
Dirt material holding tank 16 is connected with the discharge gate 14 at the back side of suction block 9.

Provided with the duct flowed through for material, the front end face of scraping blade 18 is concordant with the front of suction block 9.
During working condition, the material of melting injects at the charging aperture 5 of filter body 1, and it is backward to enter runner cavity 2
The left and right sides is flowed, by being filtered at screen pack 7, the material after filtering converged via left runner 3 or right runner 4 after from
Discharged at discharging opening 6, the impurity in material can be deposited at screen pack 7 and block the mesh of screen pack 3 during operation；
Because the driving of drive device 10 drives power transmission shaft rotation, and then discharge screw rod 8 is driven to rotate by bevel gear, discharge screw rod 8
Suction block 9 is driven to rotate, impurity can be sucked material sucking port 13 together by suction block 9 when scraping screen pack 7 in company with small part material
It is interior, discharged via discharge gate 14, a waste material part for discharge is expelled to the rear end of discharge screw rod 8 via the endoporus of discharge screw rod 8
In trash discharge runner 11, gap location discharge of another part waste material between the external screw thread of discharge screw rod 8 and inner-walls of duct, most
Eventually be also discharged at the upper end of trash discharge passage 11, finally via the discharge filter of trash discharge runner 11 outside.In the process,
Suction block 9 carries out 360 ° of rotations around discharge screw rod 8, because the positive periphery of material sucking port 13 of suction block 9 is closely pasted with screen pack 7
Close, when material extrude, one high pressure situation of the whole periphery of suction block 9 formation, but because suction block 9 the periphery of material sucking port 13 it is close
Envelope acts on so that material sucking port 13 is internally formed the area of space of an intimate vacuum, and in the presence of back pressure, material was passing through
After sieve plate 7, small part material can flow back into the inside of suction block 6, while the impurity that will be attached in the mesh of screen pack 7
Recoil enters in material sucking port 13, is expelled to via the endoporus or outer wall gap of discharge screw rod 8 in trash discharge runner 11, finally
Inside discharge filter.In the process, suction screw rod 17 is set in material sucking port 13, by suction screw rod 17 and discharge screw rod 8
Between pass through bevel gear engaged transmission so that the trash discharge efficiency in material sucking port 13 further improves, promote material sucking port 13 in
Waste material be quickly expelled in endoporus or the outer wall gap of discharge screw rod 8.Other scraping blade 18 and the setting in suction hole 19
Also suction block 9 is further enhancing to the impure dirty further suction-operated expected.
It is described above, be only the better embodiment of the present invention, any formal limitation not made to invention, it is every according to
According to the technical principle of the present invention to any simple modification, equivalent variations or modification made for any of the above embodiments, the present invention is still fallen within
In the range of technical scheme.
