Embodiment
Below in conjunction with the accompanying drawings, the present invention is described in further detail.
As shown in Figures 1 to 4, the present invention provides a kind of inverse flushing automatically cleaning continuous filter of double web plates, including filtering
Device body 1, is provided with runner cavity 2 in the filter body 1, runner cavity 2 to the left and right both sides extend left and right runner 3,
4;The front side of filter body 1 is provided with the feed inlet 5 of connection runner cavity 2, and the rear side of filter body 1 is provided with discharge port
6, left and right runner 3,4 is discharged after converging in filter body 1 through discharge port 6;Close to the left and right sides in the runner cavity 2
Region screen pack 7 is installed, the pipeline of installation discharge screw rod 8, discharge are respectively arranged with runner cavity 2 in left-right direction
There is the gap passed through for material between screw rod 8 and inner-walls of duct, discharge screw rod 8 is installed in pipeline and its front end is connected with suction
Block 9, the front of suction block 9 are contacted with screen pack 7, and 8 rear end of discharge screw rod is provided with bevel gear, the upside of filter body 1
Driving device 10 is provided with, the transmission shaft of driving device 10 stretches into its rear front end in filter body 1 and passes through bevel gear and discharge
8 rear end bevel gear engaged transmission of screw rod, the downside of filter body 1 are provided with trash discharge runner 11, and trash discharge runner 11 pushes up
Portion is located at 8 rear end of discharge screw rod, and 1 left and right ends removable seal of filter body is connected with sealing hatch door 12, the suction
It is provided with material sucking port 13 on the side that block 9 is contacted 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 8 outer wall gap location of discharge screw rod, and the discharge screw rod 8 is the cored screw of inner hollow,
8 endoporus one end of discharge screw rod 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 9 front of suction block of 15 both sides of mounting hole, and the dirt is expected
Holding tank 16 is connected with the discharge gate 14 at 9 back side of suction block.
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 with discharge screw rod 8 and between the two by bevel gear engaged transmission.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 is recessed inwardly along its length positioned at the position of dirty 16 downside of material holding tank, recessed
Sunken place offers scraping blade 18, and the hole flowed through for material is offered on dirt material holding tank 16 side wall adjacent with scraping blade 18
Road, 18 front end face of scraping blade 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 dirty 16 downside of material holding tank, inhales
Material 19 bottom of hole 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 16 downside position of dirty material holding tank in left side
19, at the 16 downside position of dirty material holding tank 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 9 one side end of suction block 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 9 front of suction block of 15 side of mounting hole to state material sucking port 13, described
Dirt material holding tank 16 is connected with the discharge gate 14 at 9 back side of suction block.
As shown in Figure 9, it is preferred that position of the front of suction block 9 on the downside of dirty material holding tank 16 is along its length
Open up fluted, tilted on groove and be placed with scraping blade 18, opened on dirt material holding tank 16 side wall adjacent with scraping blade 18
Equipped with the duct flowed through for material, 18 front end face of scraping blade is concordant with the front of suction block 9.
During working status, the material of melting injects at the feed inlet 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 discharge port 6, the impurity in material can be deposited at screen pack 7 and block the mesh of screen pack 3 during operation;
Since the driving of driving device 10 drives 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 8 rear end of discharge screw rod via the endoporus of discharge screw rod 8
In trash discharge runner 11, gap location discharge of another part waste material between 8 external screw thread of discharge screw rod and inner-walls of duct, most
Eventually be also discharged at 11 upper end of trash discharge passage, finally via 11 discharge filter of trash discharge runner outside.In the process,
Suction block 9 carries out 360 ° of rotations around discharge screw rod 8, because positive 13 periphery of material sucking port of suction block 9 is closely pasted with screen pack 7
Close, when material extrude, one high pressure situation of whole 9 periphery of suction block formation, but because suction block 9 13 periphery of material sucking port it is close
Envelope acts on so that material sucking port 13 is internally formed the area of space of an intimate vacuum, and under the action 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 will be attached to the impurity in 7 mesh of screen pack
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.In addition the setting in scraping blade 18 and suction hole 19
Also suction block 9 is further enhancing to the impure dirty further suction-operated expected.
The above, is only the better embodiment of the present invention, not makees limitation in any form 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 solution.
