Description

Grinder able to regulate granular-size without siere plate

The utility model is the improvement of beater disintegrating machine, is used for grain and feed processing industry, chemical industry is ground into required granularity with material.

The beater disintegrating machine that uses by the hammer leaf that rotates at a high speed, back and forth impacts material in pulverizing chamber at present, and material is progressively pulverized, and spills from sieve plate, is transferred air pump again and blows out the machine place.This pulverizer has following shortcoming: it is heavy that the material system is blown in the air draught of setting, causes complete machine weight big; When pulverizing different powder however with sieve plate, operation inconvenience, labour intensity is big, because the material that rotates and sieve plate friction heat up and often make the sieve plate deformed damaged at a high speed; Sieve aperture is very easily seen plug when pulverizing higher fatty acid material; Sieve plate accounts for a large amount of areas in pulverizing chamber greatly reduce the crushed work area, reduced crush efficiency.

The utility model purpose is that existing beater disintegrating machine is improved, but designs a kind of no sieve plate pulverizer of regulated at will powder size easy to use.

The purpose of this utility model reaches like this: but the no sieve plate pulverizer of regulated at will powder size, be used for the processing of grain and feed, chemical industry is ground into required granularity to material, have pulverizing chamber, polylith hammer leaf 7, the polylith tooth plate 15 formed by pulverizing chamber top 3 and pulverizing chamber bottom 4 that main shaft 2, strand connect together, of the present utility model being characterised in that; Strand company headquarters part of the epipleural 8 on pulverizing chamber top 3 and the lower side panel 9 of pulverizing chamber bottom 4 has by main shaft 2 and hole with big void area, and this hole can be square, circular or other shapes, generally with circle for well.Pulverized material enters by above-mentioned hole and is arranged on the air pump induction system of being close to epipleural 8 and lower side panel 9 and is blown outside the pulverizer.The air pump induction system connects together air pump shell top 11 and air pump shell bottom 12, impeller 10, conveying pipeline 13 by strand, and air door 16 and regulating handle 17 are formed.

Take the utility model of above measure, but the size of regulated at will powder, and adjustable range can be at the 2-180 order.Improve crush efficiency because of no sieve plate has increased the crushed work area on the one hand, operation is very simple and convenient on the other hand, has reduced labour intensity.The utility model compact conformation, handling ease, cost is low, has more given play to its advantage when pulverizing higher fatty acid material and requiring more than 100 orders trickle powder.

The utility model is described in further detail in conjunction with the accompanying drawings more below:

Accompanying drawing 1 is a structure chart of the present utility model;

Accompanying drawing 2 is A-A ' cutaway views of accompanying drawing 1.

With reference to above accompanying drawing, the material feeding partly is made of charge groove 18 and plate washer 19.Charge groove 18 usefulness iron sheets are made, and are used for feeding.Plate washer 19 usefulness sheet metals are made, and are contained in charging aperture, are used for controlling inlet amount and prevent that hard objects from entering pulverizing chamber.Pulverizing chamber top 3 and pulverizing chamber bottom 4 usefulness casting pig are cast or are welded with steel plate.Supporting base 6, supporting base 6 ' and air pump shell bottom 12 cast with pulverizing chamber bottom 4 or weld one.Pulverizing chamber top 3 connects with pulverizing chamber bottom 4 strands, so that install and maintenance.Epipleural 8 and lower side panel 9 strand company headquarters parts are opened the size of Circularhole diameter, look main shaft 2, the combination of impeller 10, air pump shell and kinetic parameter and decide, and generally this Circularhole diameter should be between main shaft 2 diameter 1.5-10 times.The tooth plate 15 that polylith is made by white cast-iron is housed in the pulverizing chamber, is fixed by bolts to pulverizing chamber top 3 and pulverizing chamber bottom 4 respectively.The working face of the tooth of tooth plate 15 is vertical with the tangential velocity of hammer leaf 7, so that material can vertically be collided with tooth plate 15 working faces, increases the material reflex, increases the hitting power of 7 pairs of materials of hammer leaf.Hammer leaf 7 is made the two ends symmetry, and after end corner angle wearing and tearing, the replaceable other end uses.Hammer leaf 7 can be made with No. 20 steels, and two is through oozing the charcoal Quenching Treatment.Hammer leaf 7 is contained on the bearing pin 23 of disk 20, generally installs 8 or 12.For keeping the invariant position of hammer leaf 7 on every row, between having, hammer leaf 7 sides manage 22. Disk 20,20 ', 20 " make with steel plate, the distance between them is with positioning sleeve 21,21 ' fixing, and is fixed on the main shaft 2 with key and positive and negative nut, and the charcoal steel is made and through heat treatment in main shaft 2 usefulness.Main shaft 2 is by bearing 5, bearing 5 ' supporting, an end fast pulley 1, and impeller 10 also is fixed on the main shaft 2.Support plate 14 that bearing 5 and bearing 5 ' be fixed by bolts to pulverizing chamber bottom 4 is equipped with and support plate 14 ' on.Air pump shell top 11 and conveying pipeline 13 can one be reinstated casting pig and are cast or weld with steel plate.Air pump shell top 11 connects with air pump shell bottom 12 strands and forms a hollow oblate cylinder more less than pulverizing chamber overall diameter, interior dress impeller 10.Conveying pipeline 13 is bend pipes of circular hollow, and its linear portions upwards is connected with the tangential direction on air pump shell top 11.Air door 16 is diameter circular steel plates more smaller than conveying pipeline 13 outlet diameters, weld regulating handle 17 above, regulating handle 17 is also rotatable near the outlet of conveying pipeline 13 by nut apparatus, regulating 17 is the air outlet area that adjustable damper 16 covers conveying pipeline 13, reaches the purpose of regulating the powder size simultaneously.

The utility model is work like this: give power sources such as belt pulley 1 configuration motor, engine by belt, material enters the pulverizing chamber that is connected together by pulverizing chamber top 3 and pulverizing chamber bottom 4 strands by charge groove 18 by gravity, be that the hammer leaf 7 of 80-90 meter per second is not held and contacted with linear velocity immediately, material is back and forth impacted between polylith hammer leaf 7 and polylith tooth plate 15 in pulverizing chamber and is progressively pulverized; Because the effect of air pump induction system, make and form negative-pressure air-flow in the pulverizing chamber, pulverized qualified powder and then carried by by the circular hole of epipleural 8, entered the air pump induction system, be blown outside the pulverizer from conveying pipeline 13 and air door 16 with lower side panel 9 straight lines strand company headquarters part by negative-pressure air-flow.Pulverized the collection of qualified powder, can be pricked a long number rice in conveying pipeline 13 exits, the coarse cloth pocket that diameter is tens of centimetres, powder can be collected in this cloth bag.Obviously, spout of the present utility model also is the air inlet of air pump induction system, and the mouth of pipe of conveying pipeline 13 also is an air outlet.When air door 16 being adjusted to conveying pipeline 13 mouths of pipe and having a specified air-out area, will form a specified negative-pressure air-flow in the pulverizing chamber.Having only this moment those to pulverize qualified pellet 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.Being pulverized qualified material will continue to be carried outside the machine of sending until pulverizing qualified by pulverizing in pulverizing chamber.Make conveying pipeline 13 mouths of pipe have different air outlet areas so regulated air door 16, essence is the size of having regulated powder.
