In order to enable those skilled in the art to be better understood from the utility model, below in conjunction with the accompanying drawings and it is embodied The utility model will be further described for mode.

As shown in Figs. 1-5, Fig. 1 discongests device for a kind of highly concentrated displacement washing defibrination of multiscrew provided by the utility model Extruding rubbing component a kind of specific embodiment structure diagram, Fig. 2 be a kind of slurry provided by the utility model A kind of structure diagram of specific embodiment of washing system, Fig. 3 are the sectional view in A-A faces in Fig. 2, and Fig. 4 is the side view of Fig. 3 Figure, Fig. 5 are the sectional view in B-B faces in Fig. 2.

A kind of multiscrew of slurry washing system highly concentrated displacement washing defibrination in the utility model is provided and discongests device, including Component 1 is crumpled in the extruding for the slurry of high concentration squeeze rubbing, is further included driving and is squeezed the first electricity that rubbing component 1 rotates Machine, certainly, the power source that driving squeezes rubbing component 1 are not limited to only motor；The device further includes the internal cylinder with chamber Body 2, wherein, it squeezes rubbing component 1 and is installed in cylinder 2, the first motor is mountable in cylinder 2 or can also be arranged on Outside cylinder 2；Along the axial direction of the chamber of cylinder 2, it is at least two extruding rubbing areas that the extruding rubbing component 1 of the device, which divides, 11, each squeezes rubbing area 11 and includes a positive-pressure spiral area and a back-pressure helical region, meanwhile, it is rubbed with the hands per two neighboring squeeze The junction for rubbing area 11 is equipped with gap 12, and the meaning in gap 12 shows to be not provided with positive-pressure spiral area or back-pressure spiral at this Area, and be not at this no any part and the occurrence of the bottom that slurry is fallen in cylinder 2 may be made, i.e. slurry By can still be conveyed during the gap 12 along before the axial direction of chamber, meanwhile, corresponding to right in circumferential direction at the gap 12 The cylinder 2 answered is equipped with several high pressure liquid filling holes 21, it should be understood that when, positive-pressure spiral area and back-pressure helical region to slurry into When row squeezes, the pressure of very big extruding force, up to 70 kilograms can be generated to slurry, so, liquid is generally by adding Area is discharged in pressure after pressure processing, could be entered in chamber by the high pressure medicine feeding hole 21 and slurry is washed, it is optional to use tricks Amount pump pressurizes to liquid, but not limited to this.Meanwhile it further includes to be set to and squeezes 1 outside of rubbing component and 2 inside of cylinder Between lining tile 4, the axial and circumferential of lining tile 4 are equipped with several through-holes 41, and cylinder 2 is equipped with several outages, at least two extruding The liquid that rubbing area 11 squeezes out is discharged into 2 outside of cylinder by several through-holes 41 and several outages.

When the device works, slurry enters extruding rubbing area 11, passes sequentially through positive-pressure spiral area and back-pressure helical region, the mistake Cheng Zhong, the pressure suffered by slurry incrementally increase, and after reaching a maximum value, suffered pressure is gradually reduced again, in the pressure area, When i.e. slurry squeezes the rubbing positive-pressure spiral area in area 11 and back-pressure helical region by first, squeeze rubbing component 1 and slurry is applied Add extruding rubbing power, carry out extruding rubbing, to remove moisture removal and some impurity of the drug, while first squeezes and crumple area 11 and the Two junctions for squeezing rubbing area 11 have gap 12, so, when slurry is transported to the junction in adjacent extruding rubbing area 11, Suffered extruding rubbing dynamics reduces, and corresponding cylinder 2 is equipped with several high pressure liquid filling holes 21 herein, and liquid passes through several high Liquid filling hole 21 is pressed to enter at the gap 12, is adequately washed with the slurry to puffy and then by next extruding Area 11 is crumpled, the extruding rubbing to slurry is carried out, removes liquid, thus, which slurry is often squeezed by one crumples area 11, just It being squeezed by positive-pressure spiral area and back-pressure helical region, slurry often crumples the junction in area 11 by two neighboring extruding, It is replaced with the once washing completed to slurry, according to production requirement, can will squeeze rubbing component 1 and divide for several extruding rubbing areas 11, multiple extruding can be carried out to the slurry of conveying and crumples and wash displacement, washing facility compared with the prior art and side Formula after discongesting device using the highly concentrated displacement washing defibrination of the multiscrew, can improve production capacity, while can reduce power consumption to reduce Cost.

The liquid added in by high pressure liquid filling hole 21 can be washings or washing liquid, can be needed to carry out according to production Selection.

Preferably, the percent opening of lining tile 4 is 12-28%, in 41 a diameter of 0.7-1.2mm of through-hole on lining tile 4.This practicality In novel, first, lining tile 4 be set, the intensity of the device is improved, can prolong the service life, secondly lining tile 4 is equipped with several high The small type hole of density, it is ensured that the fiber in slurry will not be directly discharged to outside cylinder 2 by the through-hole.

Preferably, it is bellmouth in the through-hole 41 on lining tile 4, the small openend of bellmouth is towards rubbing component 1 is squeezed, greatly Openend is towards cylinder 2.Small opening is towards rubbing component 1 is squeezed, so set, the fiber in slurry can be avoided to be extruded stranding Through-hole 41 is squeezed into during rubbing, and then blocks through-hole 41.

Further, it is circumferential corresponding to gap 12 when cylinder 2 is horizontal positioned as shown in figure 4, in present embodiment Several high pressure liquid filling holes 21 are equipped with above the side of cylinder 2 on direction.Several high pressure liquid filling holes 21 are equipped with above the side of cylinder 2, Convenient for filling operation.

In present embodiment, as shown in Figure 3 and Figure 5, lining tile 4 is made of the splicing of several unit lining tiles, several units Lining tile is removably connected with cylinder 2.So set, convenient for being safeguarded to lining tile 4, the dismounting peace of integral device is also allowed for Dress.

In present embodiment, squeeze rubbing component 1 and include at least two parallel to each other, rotating Vortex screw rods, often Root screw rod includes mandrel 13 and several first screw-casings coaxial with mandrel 13, and several first screw-casings include at least one positive pressure First screw-casing 14 and the first screw-casing of at least one back-pressure 15, several first screw-casings are socketed in mandrel 13 in an axial direction successively On；Corresponding axial position at least two screw rods is socketed between the first screw-casing of positive pressure 14 and the first screw-casing of positive pressure 14 There are gaps to form positive-pressure spiral area, and the corresponding axial position at least two screw rods is socketed the first screw-casing of back-pressure 15 And there are gaps to form back-pressure helical region between the first screw-casing of back-pressure 15.
