Mechanism to feed worm, mill in small, broken bits and the cooperation thereof of existing abrasive disk type fine crusher carries out finding after the technical Analysis, current used and the mechanism of feed worm, mill in small, broken bits and cooperation thereof have many defectives, specifically have:
1. the screw feed resistance is big, as Chinese patent application number: 03122891.7,02106311.7,200520098252.9 etc., in the given accompanying drawing of the specification of these applications, [see Fig. 1, Fig. 2 for details], just can be clear and definite find out: the helical tooth degree of depth of whole screw rod equates that everywhere the helical tooth top of whole screw rod all closely is harmonious with the screw rod transmission inside pipe wall; Such setting, though the guaranteed advantage that makes material energy high pressure enter crack crushed work district between dynamic and static mill, but because of having the elastomer material carried by screw extrusion and the strong friction of carrier pipe inwall, cause charging not only will material just be heated before entering mill crushed work district by friction with more power consumption;
2. charging thrust is too small, as Chinese patent application number: 03234405.8, in the given accompanying drawing of the specification of this application [seeing Fig. 3 for details], just can be clear and definite find out: charging only depends on the terrestrial gravitation vertical drop to realize, is not provided with feed worm; Such setting though the charging energy-saving advantages is arranged, is unfavorable for improving the output of unit;
3. feed worm can produce heat at the course of conveying of material, but is not provided with the device of how eliminating heat or living heat being cooled in feed worm in the prior art scheme, causes material just to generate heat before entering mill crushed work district;
4. be provided with the material that helps to wait to mince in the middle of the movable grinding disc and enter the water conservancy diversion in mill crushed work district with protruding Jiao Ban Stems, as Chinese patent application number: 200320118157.1 etc., in the given accompanying drawing of the specification of these applications [seeing Fig. 4 for details], can be clear and definite find out: be provided with in the middle of the movable grinding disc and be the protrusion Jiao Ban Stems that centripetal direction distributes; Treat the long-term stop of particle though this kind is provided with to have can eliminate, also keep away and unavoidably make material enter the drawback that has just been rubbed and heated by brute force before the crack crushed work district between dynamic and static mill at convergency space;
5. there is the bending angle that hinders charging at big mouthful of place of mill feed nozzle, make mill charging inaction power consumption give birth to heat, as Chinese patent application number: 95240149.5, in the given accompanying drawing of its specification [seeing Fig. 5-Fig. 7 for details], can be clear and definite find out: in mill is near, be distributed with 12 triangles on the circle tangent line, between triangle, all there is in one section round camber line link to each other, between the leg-of-mutton adjacent long edges of circular arc line and its clockwise downstream direction, just form a bending angle that hinders charging in this each section; This kind setting can make the mill charging not smooth, and heat is given birth in the power consumption of inaction;
6. the sharp end of the mill feed nozzle of She Zhiing, is near partially from mill outlet edge, make the mill workspace distance of that a part of coarse fodder process of being advanced by the sharp-tongued end of charging short partially, cause this part material of walking the short circuit journey to be pulverized inadequately, finally can cause the bad result who has the meal ratio big in the overground product; As from the Figure of description of Chinese patent (application number) 02106311.7 [see for details Fig. 1 (, Fig. 2], can be clear and definite find out: in mill is near, being distributed with 17 triangles on the circle tangent line, each leg-of-mutton summit to the mill outer edge all be close to run into outside the mill along the line;
7. also there is defective in cooperating between feed worm and mill in small, broken bits, specifically: have the bigger space that gathers materials between screw rod end and movable grinding disc; As Chinese patent application number: 96247279.4 etc.; in the given accompanying drawing of the specification of these applications [seeing Fig. 8 for details]; can be clear and definite find out: between screw rod end and movable grinding disc, have the bigger particle pause convergency space for the treatment of; when grinding machine is worked; this space abrim during charging in advance a part do not advance gathering materials always of mill crushed work district; this gathers materials always and is constantly rubbed by movable grinding disc center face; this situation one is the invalid pulverizing electricity consumption that can increase pulverizer; the 2nd, can limit the material kind that fine crusher is handled; so plant fine crusher and be not suitable for handling thermoplastic material exactly; because thermoplastic material this kind machinery treat can be heated fusion in the particle convergency space; the heat fusing material finally can stop up the powder passage, finally makes the motor overload of the feed worm that drives fine crusher; jump electric brake and shut down.
Defective to the prior art existence, only be once to have patent application to propose to attempt to eliminate the scheme in the space that gathers materials that exists between feed worm end and movable grinding disc in small, broken bits, as Chinese patent application number 02106311.7, this application case is all mentioned in its claims and specification, the technical scheme of this utility model application is characterised in that: " movable grinding disc is provided with endoporus, and the screw rod end enters in the movable grinding disc endoporus "; But this application case does not all provide the technical scheme content of described " movable grinding disc is provided with endoporus, and the screw rod end enters in the movable grinding disc endoporus " in the explanatory note and accompanying drawing of embodiment; This application case has just provided in the embodiment accompanying drawing: movable grinding disc is provided with the flat indent of circle by the one side of screw rod end, and the screw rod end is stretched in the flat indent of movable grinding disc circle of setting;
