A kind of spiral shell pressing dehydrator provided by the invention, structure and principle can be briefly described are as follows:
All components of the equipment are fixed on rack, and screw spindle 5 passes through rack-mounted front-end bearing pedestal 2 and rear axle
The support of seat 8 is held, and is connect with motor reducer 1, drives screw spindle 5 to rotate by motor reducer 1；
Material is entered by feed hopper 3, is driven material to move ahead by screw spindle 5 and is squeezed to material, wherein squeezes out
Liquid filtered out by the cylinder mould 4 being fixed between feed hopper and support plate, and enter connect liquid bath；The solid squeezed out passes through branch
Gap between fagging and clamping adjustment device is extruded away, passes through 9 discharging of discharge cover；Outer cover 6 plays beauty, splashproof, close
Seal the effect of anti-peculiar smell.
A kind of spiral shell pressing dehydrator provided by the invention has following special designing:
1, screw spindle is pyramidal structure, convenient for the dehydration of material.
2, cylinder mould uses opposite opened structure, relatively repairs, installs.
3, cylinder mould support is bolted all using upper and lower two parts, is easily installed disassembly.
4, motor uses variable-frequency motor, adjustable speed.
5, all connecting components are easily installed, repair, transport using being threadedly coupled.
6, main shaft wearability is good.
7, the cylinder mould 4 used inside spiral shell pressing dehydrator is cylindrical filter sieve, according to the difference to material, filter screen
Gap is also different, the kitchen remaining meal rubbish classified, biogas residue rubbish is injected wherein by feed hopper, then by internal slow
The screw spindle 5 of rotation, which slowly pushes, to advance, and is furnished with clamping adjustment device 7, dewatered kitchen remaining meal rubbish in 4 end of cylinder mould
Rubbish, biogas residue rubbish are uniformly squeezed out in the cone bucket body surrounding annulus of clamping adjustment device 7, from hopper throat to discharge port, spiral
The spindle main body of main shaft 5 is the ascending back taper figure of diameter, and the depth of helical blade is descending, changes the storage of material
Space is deposited, is excluded so that the moisture in rubbish is extruded through cylinder mould 4, the size of squeeze force is by adjusting clamping adjustment device
7 realize that cylinder mould cleaning interval can rinse outside cylinder mould to realize to change discharge port size.
The present invention also provides a kind of dewaterings based on spiral shell pressing dehydrator, comprising the following steps:
Step 1, start motor reducer 1, motor reducer 1 drives screw spindle 5 to rotate；
Step 2, clamping adjustment device 7 is operated, the size of squeeze force is adjusted；
In step 2, clamping adjustment device 7 is operated using following methods, to adjust the size of squeeze force:
When needing to tune up squeeze force, rotation hand wheel 7.2, handwheel 7.2 advances along axle sleeve 7.1；Since handwheel 7.2 passes through bullet
Spring 7.3 and push-plate sleeve 7.4 are fixed, and push-plate sleeve 7.4 and push-plate 7.5 are fixed, therefore, when handwheel 7.2 advances, push
Push-plate 7.5 travels forward, and then makes to push away in the outer rim constantly hole of the row's of entering solid pores 13.1 of push-plate 7.5 to turn down
Thus squeeze force is improved since the aperture that material can be discharged becomes smaller in disk 7.5 and row 13.1 gap of solid pores；
When needing to turn squeeze force down, handwheel 7.2 is reversely rotated, handwheel 7.2 is retreated along axle sleeve 7.1；Since handwheel 7.2 is logical
It crosses spring 7.3 and push-plate sleeve 7.4 is fixed, and push-plate sleeve 7.4 and push-plate 7.5 are fixed, therefore, when handwheel 7.2 retreats,
It pulls push-plate 7.5 to move backward, and then makes hole of the outer rim of push-plate 7.5 constantly far from row's solid pores 13.1, pushed away to tune up
Thus disk 7.5 and row 13.1 gap of solid pores reduce squeeze force since the aperture that material can be discharged becomes larger.
Step 3, material enters from feed hopper 3, and the preceding end in contact with screw spindle 5；In the turning effort of screw spindle 5
Under, screw spindle 5 drives material to move backward, during material moves backward, since the diameter of cylinder mould 4 is constant, and spiral shell
The diameter for revolving main shaft 5 is increasing, and therefore, the squeezing space between screw spindle 5 and cylinder mould 4 is smaller and smaller, and squeeze force is more next
Bigger, the squeeze force constantly increased squeezes material, squeezes out the liquid come and is filtered out by cylinder mould 4, and is flowed into and connects liquid
In slot 12；Gap of the solid particle come between clamping adjustment device 7 and row's solid pores 13.1 is squeezed out to be extruded away, and
It enters in discharge cover 9；To finally realize the effect of material dewatering.
A kind of spiral shell pressing dehydrator and dewatering provided by the invention, have the advantage that
1, it is designed exclusively for kitchen, food waste, biogas residue dehydration, there is optimal utilization rate of equipment and installations and minimum spiral shell
It revolves the speed of mainshaft (15-20 revs/min).
2, movable part is few, is made of robust stainless steel structure.
3,24 hours continuously-runnings of equipment.
4, small investment, it is compact-sized, save space.
5, technically simple, it is reliable for operation.
6, noiseless without friction, full-closed structure, it is pollution-free.
7, easy to repair.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
Depending on protection scope of the present invention.

Step:
Step 1, start motor reducer (1), motor reducer (1) drives screw spindle (5) rotation；
Step 2, clamping adjustment device (7) are operated, adjusts the size of squeeze force；
Step 3, material enters from feed hopper (3), and the preceding end in contact with screw spindle (5)；Make in the rotation of screw spindle (5)
Under, screw spindle (5) drive material move backward, during material moves backward, due to cylinder mould (4) diameter not
Become, and the diameter of screw spindle (5) is increasing, therefore, the squeezing space between screw spindle (5) and cylinder mould (4) is increasingly
Small, squeeze force is increasing, and the squeeze force constantly increased squeezes material, squeezes out the liquid come and is filtered by cylinder mould (4)
Out, it and is flowed into and connects in liquid bath (12)；Squeeze out come solid particle from clamping adjustment device (7) and row solid pores (13.1) it
Between gap be extruded away, and enter in discharge cover (9)；To finally realize the effect of material dewatering.
8. dewatering according to claim 7, which is characterized in that in step 2, operated using following methods and compress adjusting
Device (7), to adjust the size of squeeze force:
When needing to tune up squeeze force, rotation hand wheel (7.2), handwheel (7.2) advances along axle sleeve (7.1)；Since handwheel (7.2) are logical
It is fixed to cross spring (7.3) and push-plate sleeve (7.4), and push-plate sleeve (7.4) is fixed with push-plate (7.5), therefore, works as handwheel
(7.2) when advancing, push-plate (7.5) are pushed to travel forward, and then make the outer rim constantly row's of entering solid pores of push-plate (7.5)
(13.1) in hole, so that push-plate (7.5) and row solid pores (13.1) gap have been turned down, since the aperture that material can be discharged becomes
It is small, thus improve squeeze force；
It when needing to turn squeeze force down, reversely rotates handwheel (7.2), handwheel (7.2) is retreated along axle sleeve (7.1)；Due to handwheel
(7.2) fixed by spring (7.3) and push-plate sleeve (7.4), and push-plate sleeve (7.4) and push-plate (7.5) are fixed, therefore,
When handwheel (7.2) retreat, push-plate (7.5) is pulled to move backward, and then makes the outer rim of push-plate (7.5) constantly far from row's solid pores
(13.1) hole, so that push-plate (7.5) and row solid pores (13.1) gap have been tuned up, since the aperture that material can be discharged becomes larger,
Thus squeeze force is reduced.
