The specific embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of can solve the putty phenomenon, obtain better squeezing effect and than the centrifugal screw extruder of high efficiency.
Embodiment 1,
As shown in Figure 1; A kind of centrifugal screw extruder comprises cabinet 1, feed pipe 2, transmission device and discharge gate 3, between said feed pipe 2 and said transmission device, is equiped with screw rod hollow shaft 4; Also be equiped with the filter screen 5 that to follow said transmission device rotation; Said filter screen 5 is arranged at said screw rod hollow shaft 4 peripheries, between said filter screen 5 and said cabinet 1, is provided with the liquid collecting room 6 that is used to collect filtrating, forms annular compartment between said filter screen 5 and the said spiral hollow shaft 4.
In the technique scheme, can make filter screen 5 rotation at a high speed of extruder, increase centrifugal force; Because the action of centrifugal force material can tightly be attached to screen surface; Increase the frictional force of 5 of material and filter screens greatly, avoided the friction of 5 of material and said filter screens too small, thereby cause material circumferentially to skid on filter screen 5 surfaces; Allow to improve the extruding force of screw rod with this, obtain more dried solid formation.
Because the rotation of the high speed of filter screen, material also receives the extruding of centrifugal force, and when promptly said centrifugal screw extruder was worked, material received the mechanical force extruding of centrifugal force extruding and screw rod simultaneously, and it extracts efficient has had breakthrough raising.
Said screw rod hollow shaft 4 is provided with helical blade 41; Said helical blade 41 helical pitches are reduced to said discharge gate 3 directions by said feed pipe 2 gradually; The spacing that is per two adjacent helical blades 41 is reduced to said discharge gate 3 directions by said feed pipe 2 gradually; Form ring-type crush zone 7 between said helical blade 41 and said filter screen 5 and the said screw rod hollow shaft 4, said crush zone 7 is reduced to said discharge gate 3 directions by said feed pipe 2 gradually, has increased the mechanical presses power of screw rod with this.
Be provided with pre-concentration district 8 between the front end of said screw rod hollow shaft 4 and the said filter screen 5; Be provided with tapping bucket 11 with said pre-concentration district 8 with said crush zone 7 corresponding said cabinets 1 below, also be provided with discharge bucket 12 with said discharge gate 3 corresponding said cabinets 1 below.
Feed zone at centrifugal screw extruder increases a centrifugal pre-concentration district 8; Overwhelming majority liquid is separated at enrichment region; Can obtain the few filtrating of solid content, the filtrating of crush zone 7 can be taken the part solid formation out of, but its filtrating total amount seldom; Can turn back in the feeding liquid or the single collection otherwise processed, obtain the lower filtrating of solid content.
Its operation principle is: starting device, and filter screen 5 is rotated under the drive of transmission device, and said screw rod hollow shaft 4 is rotated with the speed that is lower than said filter screen 5 rotations; Material is poured into from said feed pipe 2, and material enters in the screw rod hollow shaft 4 from feed pipe 2, in pre-concentration district 8; Liquid sees through filter screen 5 and flows to the liquid collecting room 6 of collecting filtrating, and the solids after concentrating gets into crush zone 7; The helical pitch of the helical blade 41 of screw rod is more and more littler, and solid is extracted the back and discharged from discharge gate 3, and the filtrating of extruding flows in the liquid collecting room 6 through filter screen 5; Solid is discharged extruder from discharge bucket 12, and the enrichment region filtrating enrichment region tapping bucket 11 corresponding from the below flows out, and the crush zone filtrating crush zone tapping bucket 11 corresponding from the below flows out; The filtrating of enrichment region and the visual technological requirement of the filtrating of crush zone are handled respectively or are united two into one; Certainly, the filtrating of crush zone can also turn back to feed pipe 2 and filter again, to obtain the lower filtrating of solid content.
Adopt the centrifugal screw extruder that the utility model provided, through being equiped with rotatable filter screen 5, because the action of centrifugal force material can be close to filter screen 5 surfaces; When carrying out Separation of Solid and Liquid, the rotary speed of adjustment filter screen 5, the rotary speed of reduction screw rod hollow shaft 4; With this frictional force that increases by 5 of material and filter screens, effectively avoided material circumferentially to skid, thereby could improve the extruding force of screw rod on filter screen 5 surfaces; Obtain more dried solid formation, improved production efficiency.
As shown in Figure 2, all the other are same as the previously described embodiments, and difference is; The size of said screw rod hollow shaft 4 is increased to said discharge gate 3 directions by said feed pipe 2 gradually; Then the corresponding annular chamber diminishes gradually, when screw rod hollow shaft 4 rotates, pushes towards material; Material obtains the extruding force that progressively strengthens thus, can reach above-mentioned and can solve the putty phenomenon, obtain better squeezing effect and than the purpose of high efficiency.
Embodiment 3,
As shown in Figure 3, all the other are same as the previously described embodiments, and difference is that said filter screen 5 sizes are reduced to said discharge gate 3 directions by said feed pipe 2 gradually, and then helical duct is more and more littler, and material obtains the progressively extruding force of increasing.
In the present technique scheme; Said filter screen 5 sizes are reduced to said discharge gate 3 directions by said feed pipe 2 gradually, can in embodiment 1 and/or embodiment 2, implement, and also can implement separately; Concrete embodiment is determined on a case-by-case basis; At this, the utility model is not done any qualification, is main can realize the utility model.
Technique scheme can also be used for the slurries of other fibrousness solids are carried out the technology of continuously extruded dehydration except the solid-liquid separation process that is applied to the reconstituted tobacoo extract, like paper pulp, wine lees liquor etc.
Pass through technique scheme; The beneficial effect of the utility model technical scheme is: a kind of centrifugal screw extruder; Comprise cabinet 1, feed pipe 2, transmission device and discharge gate 3; Between said feed pipe 2 and said transmission device, be equiped with screw rod hollow shaft 4, also be equiped with the filter screen 5 that can follow said transmission device rotation, said filter screen 5 is arranged at said screw rod hollow shaft 4 peripheries; Said screw rod hollow shaft 4 is provided with helical blade 41, between said filter screen 5 and said cabinet 1, is provided with the liquid collecting room 6 that is used to collect filtrating; Adopt the centrifugal screw extruder that the utility model provided, through being equiped with rotatable filter screen 5, because the action of centrifugal force material can be close to filter screen 5 surfaces; When carrying out Separation of Solid and Liquid, the rotary speed of adjustment filter screen 5, the rotary speed of reduction screw rod hollow shaft 4; Increase the frictional force of 5 of material and filter screens with this; Thereby make the frictional force of screw spiral blade 41 and material less than the frictional force of material and filter screen 5, through action of centrifugal force, make material as much as possible away from said screw rod hollow shaft 4 to filter screen 5 near; Improve the extruding force of screw rod hollow shaft 4 again; Effect through mechanical presses power obtains more dried solid formation, has effectively avoided originally following the crowded situation about not doing of solid that the screw rod hollow shaft circumferentially skids and causes because of material, has effectively improved production efficiency.
