Abstract

Double spinning powder mill is a machinery mill for crushing for glass sand. The prior powder mill is that glass is crushed by impact force created from the rotation of a break hammer driven by a mandrel, and the finish sand comes from sieved sand with different granularity by mixing on a solid sieve plate. However, the mixing created from the crushing of the break hammer is not to sieve finish sand out. In such double spinning sand mill are fixed with a spinning break sieve body and a break impeller, such break sieve body is constituted by the flange fixed at one end of a hollow axis coupled on round ring shape break sieve body, and sieve sand break plate on such circular ring rack of the break sieve body and a combined hole sieve plate with multiple curved slice, and gears are fixed one end of the hollow axis in the machine frame and the break impeller is fixed at the other end of the mandrel. The mandrel, fixed at the other end of the hollow axis hole, is driven by a belt pulley to form separated running with the hollow axis, forming a coaxial differential running with break impeller. The sand grain to granularity standard is sieved out in time during spinning of break sieve body.

Description

Bispin flour sand mill

(1) a kind of fragmentation of producing glass sand of technical field is ground with machinery.

(2) background technology production glass sand is that cullet piece or cullet bottle are ground the glass sand grains that is processed into the granularity that meets the requirements with flour sand, just become waste product less than the sand grains that requires granularity, go out less the waste product most critical just be that glass blocks is broken in flour sand mill the time, whether the sand grains that reaches the requirement granularity can in time separate is sifted out, and the flour sand mill that possesses this performance could be realized high finished product rate, high production rate, low consumption.Existing hammer flour sand mill is formed body by the upper casing of assembling crushing shell and the lower casing of assembling sieve plate, and the centre of upper and lower enclosure is the rotary main shaft of assembling quartering hammer.Its operation principle is that the main shaft rotation drives the quartering hammer on the main shaft, the impact force action that quartering hammer produces is on the fixed screen deck of the stationary crushing plate of upper casing and lower casing, make glass blocks be broken into sand grains, the shortcoming of this flour sand mill is, shake out is by the stirring of quartering hammer when the broken glass piece, the hole sizer of sand grains on fixed screen deck gone out, the glass sand that has reached the requirement granularity in shattering process can not in time separate with big grain glass sand, big grain glass sand can stop the hole on the sieve plate again, a feasible part should be worked as qualified sand grains and be broken into waste product, so the yield rate of existing flour sand mill also has only about 75%.Cause the high loss of high energy consumption and flour sand grinding machine spare.

(3) the low main cause of the existing flour sand mill yield rate of summary of the invention is exactly that the sand grains that reaches the requirement granularity in the shattering process can not in time separate and sifts out, and technical problem underlying to be solved is the sieve nest structure of flour sand mill.The sand grains that reaches the requirement granularity can in time be separated to be sifted out, the purpose of this utility model provides the broken sieve nest of a kind of rotation of assembling sand screening crushing plate and multi-patch hole Combined sieve board, the application's product bispin flour sand mill that rotates with broken impeller concentric differential on the main shaft.The broken sieve nest of bispin flour sand mill is to constitute the broken sieve nest of rotation by the end that garden ring crush screen frame flange connecting dish is assemblied in hollow shaft, there is bearing in the outer garden that rotates broken sieve nest hollow shaft, be assemblied in the body frame rotatable, the other end of hollow shaft has gear drive to make broken sieve nest rotation, assembling sand screening crushing plate and multi-patch combination bore sieve plate on the loop bracket of annular screen frame, sand screening crushing plate is to have increased sieve aperture in the broken rib groove of crushing shell, make crushing shell in fragmentation, also have both sieve sand function, become sand screening crushing plate, multi-patch combination bore sieve plate is with the rolling many S type knee-piece of band steel, the relative sieve aperture that constitutes of the convex surface of knee-piece with convex surface, the multi-patch combination bore sieve plate that is combined into by a plurality of knee-pieces, sieve sand is fast, shakes out evenly, low cost of manufacture.It is to be made of garden dish and uniform being connected on the card of garden of many group blades that the bispin flour sand galls leaf cutting wheel, on the blade face of broken blade and the broken leaf wheel face corresponding radial centre lines have be adapted to broken need ± 0 °～178 ° angle excursion, broken impeller has centre bore to cooperate with main shaft one end, bearing is arranged on the main shaft, main shaft is assemblied in the hollow axis hole, the other end of main shaft has belt pulley transmission and hollow shaft to form separately independently transmission running, take such scheme to realize that the concentric differential of broken sieve nest and broken impeller rotates, the sand grains that reaches the requirement granularity is in time separated in the rotation of broken sieve nest to be sifted out, yield rate and productivity ratio have been improved, reduce sand grains to machine members, reduced energy consumption and production cost.
