On casing 2, the screen drum 3 in casing 2, the helical blade 4 in screen drum 3, installed in the front side of casing 2 and and spiral shell
Bearing block 11 that vane piece 4 is connected, it is connected with bearing block 11 to drive the motor reducer 1 of the rotation of helical blade 4, located at casing
2 upside and feed hopper 21, the water receiving tank 22 located at the downside of casing 2, the discharge bucket located at the rear side of casing 2 being connected with screen drum 3
23rd, two cylinders 24 and the two discharging pressing plates 25 driven respectively by two cylinders 24.The in-cylinder pressure of cylinder 24 is adjustable
Section, its cylinder body is hinged on the left and right sides of casing 2.The middle-end of discharging pressing plate 25 is hinged on the rear side of casing 2 as fulcrum, and it two
One end and the piston rod of cylinder 24 in end are hinged, and the other end is connected on the hatch door of discharge bucket 23.
The cross section of feed hopper 21 is in up big and down small right-angled trapezium shape, arranged direction and the helical blade 4 of right-angled trapezium
Related (starting point that helical blade is rotated is the right-angle side of right-angled trapezium, and the terminal that helical blade is rotated is right angle for direction of rotation
Trapezoidal hypotenuse).As shown in figure 3, the right-angle side of right-angled trapezium is located in the tangential direction of helical blade, its hypotenuse root is away from sieve
The screen drum diameter D for being equal to 1/6th apart from A of cylinder inwall.In the present embodiment, screen drum 3 is justified by steel plate ring thick 6-12mm, and
Densely covered 4-15mm sieve aperture 31 is machined with along its periphery.It is provided with the inwall of screen drum 3 some parallel to the axis of screen drum 3
The conveying and cut-out of tread plate 32, it is to avoid material skids in screen drum, more conducively material, tread plate 32 according to abrasion condition more
Change.
As shown in figure 4, preferably to convey material, preventing fabric in material etc. to be wrapped on helical blade 4 and cause
Shaftless spiral blade is used in failure, the present embodiment, the diameter D of spiral is 300-1000mm, and the hole size of spiral is (1/3-
1/4) D, the length (L2 in Fig. 4) that helical blade is located at the spiral section of the lower section of feed hopper 21 is (0.7-1) D, final stage (Fig. 4
Middle L1) pitch be (0.6-0.8) D, spiral end away from discharging pressing plate apart from size (L in Fig. 4) be (0.7-1) D.
The Shaftless spiral blade is different in the cross sectional shape of diverse location, as shown in Figures 4 and 5, and it is located at feed hopper
The cross sectional shape of the spiral section (in Fig. 4 L2 sections) of lower section is trapezoidal, and its cross-sectional width B sizes are equal to (0.1-0.12) D, otch C
Size is equal to (0.6-0.8) B, and remaining section is the rectangle that cross-sectional width is B, as shown in L1 sections in Fig. 4.The purpose being arranged such
It is：1st, trapezoid cross section upper width is small, can prevent material undercarriage from blade, being rotated together with blade, causing material can not
Push ahead；2nd, in same area charging aperture, the relatively long aspect section in up-small and down-big trapezoid cross section can increase charging area.
To avoid material from being stuck between helical blade and screen drum, and cause material to build bridge and influence production, as shown in fig. 6,
Feed hopper 21 is provided with stationary knife 211 towards the inwall of that side of discharge bucket and the junction of screen drum 3, and helical blade 4 is located at charging

In the present embodiment, the motor that motor reducer 1 is used is variable-frequency motor, and it can be changed by the feedback of electric current
The running frequency of motor, when the current increases, the running frequency increase of motor.
The course of work：
Material enters from feed hopper 21, and the driving helical blade 4 of motor reducer 1 rotates, the rotation forces material of helical blade 4
Advance, material is proceeded to up to discharging pressing plate 25, set pressure because material forward thrust is less than cylinder 24, in figure 4 L length
On material formation material plug, helical blade 4 continues rotation forces subsequent materials and advances, and material is formed with discharging pressing plate 25 front end
Material plug rubs mutually extrusion dehydration, the water arrival screen drum 3 of abjection is discharged to water receiving tank 22 by sieve aperture 31 and drained；Helical blade 4 is held
Continuous rotation forces subsequent material advances, and material forward thrust persistently increases, and pressure is set when material forward thrust is more than cylinder 24
When, discharging pressing plate 25 is opened, and material discharges dehydration equipment by discharge bucket 23 after dehydration；After dehydration after material discharge, spiral shell is dehydrated
Medial rotation material pressure declines, when material forward thrust persistently reduces and sets pressure less than cylinder 24, and discharging pressing plate 25 is closed,
Now one enters dewatering spiral to discharge dewatering spiral process completion from material.Restart next from material entrance dehydration
It is threaded to discharge dewatering spiral process；When the inventory of moment feed hopper 21 is big, the increase of the electric current of motor reducer 1 passes through electric current
Feedback increase motor reducer 1 frequency increase helical blade 4 faster rotational speed material advance extruding discharge causes equipment not because mistake
Carry and cause production disruption.
It is described above, only the utility model preferably embodiment, but protection domain of the present utility model is not
