Abstract

The utility model relates to a hammer pulverizer capable of free controlling over product grading, which comprises a pulverizing chamber, a fan chamber, a feed system, a discharge system, etc. The casing between the pulverizing chamber and the fan chamber is embedded with a fixed tray for dividing the two chambers and a movable tray capable of rotating round the fixed tray. The movable tray is provided with sieve meshes and big holes, and the fixed tray at the part corresponding to the sieve meshes of the movable tray is provided with big hole which are identical with the sieve meshes. The coincident degree of the big holes on the fixed tray, and the sieve meshes and the big holes on the movable tray can be controlled through wrenching a regulating handle to rotate so that the granularity of finished products can be regulated accurately, conveniently and optionally.

Description

Pulverizer with freely controlling product grading

The utility model relates to beater disintegrating machine, the device of control finished product fineness degree on the particularly this pulverizer.

At present; that generally uses in grain and feed processing industry, chemical industry has a sieve pulverizer; by its sieve sheet installation situation; can be divided into end sieve formula, ring grizzly formula and side and sieve three kinds of formulas; no matter the pulverizer of which kind of form when regulating the finished product granularity, all must be realized by shutting down the sieve sheet of changing different apertures; time-consuming, the sieve sheet also damages easily.CN87211018U has announced a kind of " but no sieve plate pulverizer of regulated at will powder size ", after this pulverizer is pulverized material in pulverizing chamber, be to make in the pulverizing chamber by damper to form a specified negative-pressure air-flow, make those have only the qualified pellet of pulverizing just can overcome self gravitation and centrifugal force and be carried to the air pump induction system by this specified negative-pressure air-flow and blow out outside the pulverizer again.Though this pulverizer has overcome the problems referred to above that the sieve pulverizer is arranged, it is difficult to accurately regulate and control the finished product granularity.

The purpose of this utility model is to improve the device part of control finished product fineness degree on the existing pulverizer, particularly pulverizer, provides a kind of both easy to operate, can accurately regulate and control the pulverizer of finished product fineness degree again.

The utility model purpose is achieved in that in the beater grinder that comprises pulverizing chamber, fan room, charging and discharge system etc. that hammer leaf is housed, is that one group of granularity control device that two Room are separated is set in the casing between pulverizing chamber and fan room.This granularity control device comprises the price fixing that is embedded in the engine housing, and be embedded in the price fixing chute and can rotate and the Moving plate that has a regulating handle is formed along chute, several sieve aperture and alternate macropores between sieve aperture of being made of numerous aperture are arranged on the Moving plate, price fixing with Moving plate on the sieve aperture corresponding section the empty macropore of control is arranged.During work, extend the outer Moving plate regulating handle of engine housing, regulate that the macropore on sieve aperture, macropore and the price fixing overlaps degree on the Moving plate, can control material and pulverize laggard granularity of going into fan room in pulverizing chamber by moving.

The shared area that has of sieve aperture is greater than big hole area on the utility model Moving plate.When the hole diameter on the Moving plate sieve aperture was chosen in 0.5～1.5 millimeter scope, the granularity of finished product can be regulated arbitrarily in 0.2～0.8 millimeter.

After the utility model adopts such scheme, can under non-stop-machine situation, regulate the fineness degree (granularity) of finished product arbitrarily, easily and accurately.

Below in conjunction with drawings and Examples the utility model is further specified.

In the drawings, link in the cylindrical casing that constitutes by upper casing 16 and lower casing 3, main shaft 7 is equipped with at the casing center, be fixed with rotating disk 6 and blower fan 15 on the main shaft 7 simultaneously, 8 hammer leaves 2 are housed on the bearing pin 5 of rotating disk 6, and the tangential velocity of hammer leaf 2 is perpendicular to the tooth plate 1 that is fixed on upper casing 16 and the lower casing 3.Price fixing 13 and Moving plate 14 are inserted in main shaft 7 places between rotating disk 6 and the blower fan 15, and interior pulverizing chamber of casing and fan room are separated.Wherein circular price fixing 13 radiuses equal radius of circle in the casing, and there are four projectioies at the edge and are embedded in the groove that leaves in the upper and lower casing 16,3, by closing upper and lower casing price fixing is fixed again; Circular Moving plate 14 is slightly smaller than price fixing 13 and is connected with regulating handle 11, and Moving plate 14 is embedded on the price fixing 13 by chute 17 usefulness bolts location and can rotates in chute 17, and regulating handle 11 extends outside the casing by the guide hole of casing.4 waist shape sieve apertures 18 are arranged on the Moving plate 14, and sieve aperture 18 is to be made of numerous 0.5～1.5 millimeter aperture, and four circular macropores 19 are arranged on Moving plate 14 gaps between the sieve aperture 18, and the area that sieve aperture 18 is occupied is a times of macropore 19 areas.And have on the price fixing 13 of Moving plate sieve aperture 18 corresponding sections four with the identical macropores 20 of sieve aperture 18 sizes.

During work, be directly to feed coarse fodder or fine fodder from feeding trough 8 or material box 9, material enters pulverizing chamber and pulverizes, move regulating handle 13 simultaneously, when Moving plate sieve aperture 18 is overlapped fully with price fixing macropore 20, Moving plate macropore 19 is shut fully, and the finished product after pulverize this moment directly enters fan room through Moving plate sieve aperture 18 and price fixing macropore 20 and inhaled outside the warp let-off discharge gates 12 discharge machines finished product granularity that obtains the thinnest (corn is 0.2 millimeter) again by blower fan 15.As will obtain thicker finished product the time, be to move regulating handle 13 Moving plate macropore 19 is overlapped with price fixing macropore 20 gradually, the price fixing macropore 20 that this moment, material after crushed can be simultaneously enters coincidence through Moving plate sieve aperture 18 and Moving plate macropore 19 enters fan room again, when Moving plate macropore 19 overlaps fully with price fixing macropore 20, the finished product granularity that obtains the thickest (corn is 0.8 millimeter).
