Description

Efficient hammer crusher

The utility model relates to a kind of pulverizer, particularly a kind of hammer crusher that is applied to grain, feed, medicine, chemical products processing.

Hammer crusher is a grain, feed, medicine, the most frequently used machinery in the chemical products processing, present being seen hammer crusher uses motor or diesel engine to be used as power, its structure comprises belt pulley, rotating shaft, vicarious, rotor, be installed in epitrochanterian hammer leaf, charging aperture, air inlet, pulverizing chamber, screen frame, discharging opening and attached parts such as ventilation and dust removal equipment, the charging aperture and the air inlet of most of pulverizers are integrated, lower box in the pulverizing chamber is only installed the sieve sheet of a monoblock, preceding tooth plate and back tooth plate are all made helical teeth shape, the hammer crusher of this type exists following weak point: 1. because charging aperture is again an air inlet, make the inlet amount instability, air quantity is little when big also the time, pulverizing chamber is easily produced impact fluctuation, the current of electric instability, bearing easily generates heat; 2. when intake was unstable, it is even that material enters the pulverizing chamber mass flow discrepancy, reduced crush efficiency, influences processing output; 3. the screen frame area is little, yield poorly, and specific yield consumption rate height, and also screen frame makes with monoblock sieve sheet, has some damages then will all change slightly; 4. preceding tooth plate in the pulverizing chamber and back tooth plate all adopt helical teeth, make material become the circumference rotation in pulverizing chamber, and hammer leaf hits less than material, and output is difficult to improve; 5. do not separate before foreign material, stone, metal such as the charging, very easily bring pulverizing chamber into and cause hammer leaf and sieve sheet to damage.In order to overcome the shortcoming of existing hammer crusher, have the people that its structure has been carried out some and improve, if any the increasing screen area, as No. 96116579 Chinese patents; The shape of the change pulverizing chamber that has is as No. 99205702 Chinese patents; What have establishes two charging apertures, as No. 99208928 Chinese patents; But the change that the hammer crusher of open source literature report has shape and structure, caused part processing nonstandard, give and make and maintenance has brought inconvenience; The structure that has is complicated, implement also difficult, the basic structure of its pulverizing chamber that main is and charging, air intake has determined their characteristics and performance, makes the hammer crusher energy consumption height of existing market finding and bibliographical information, the situation that yields poorly be difficult to obtain bigger change.

The purpose of this utility model provide a kind of can overcome the prior art weak point, superior performance, capable of reducing energy consumption and increase substantially the efficient hammer crusher of output.

The technical solution of the utility model is to solve like this: efficient hammer crusher comprises charging aperture, air inlet, pulverizing chamber, rotor, rotating shaft, bearing, belt pulley, discharging opening, drive the motor of belt pulley or the actuating unit of diesel engine, the parts such as exhaust equipment that are connected with discharging opening, be characterized in below the charging aperture hopper, being provided with the air inlet adjustment plate on one side, establish separation stone on one side, the separation adjusting plate of foreign material such as metal, upper box cup in pulverizing chamber is equipped with the helical teeth plate, mountain type tooth plate is then installed in back chamber, the lower box screen frame of pulverizing chamber is by the both sides side bayonet slot, intermediate screening card article and be installed in draw-in groove, two or some sieve sheets formations in the card article, and set up side in the two sides of lower box and sieve sheet, set up three air inlets in the back of lower box, and change existing plain bearing into self-aligning bearing, be provided with locking device between upper box and the lower box.

The course of work and the principle of this efficient hammer crusher are, material falls from the hopper mouth, because the hopper below is provided with the foreign material separating opening, stone, ironware, silt particle can be discharged from separating opening, last wind-supplying mouth can be regulated intake by the foreign material separating plate, material enters after the pulverizing chamber because pulverizing chamber upper box cup adopts the helical teeth plate, mountain type tooth plate is adopted in back chamber, reduce the circular motion speed of material, increased the mixed flow rate, improved relative velocity and crush efficiency that hammer leaf hits material greatly, again owing to set up two sides sieves and three following wind-supplying mouths in pulverizing chamber lower box side, material is in time drawn from discharging opening by air-introduced machine after pulverizing, improved output greatly, in addition, existing plain bearing is changed to self-aligning bearing, can carry out automatic aligning to the deviation of rotor operation process, the running temperature rise is low, has prolonged the life-span of axle and bearing.

The utility model is compared with existing hammer crusher, and its outstanding substantive distinguishing features and obvious improvement is:

1. increased air inlet, material inlet and air inlet are separated, regulated at will is determined inlet amount and intake according to the working condition of pulverizing chamber, guarantees the pulverizer stable working.

2. in the upper box front portion of pulverizing chamber the helical teeth plate is installed, and mountain type tooth plate is installed at the upper box rear portion, making material is not to make stable circular motion in pulverizing chamber, but increases randomness, makes hammer leaf hit the increase of material probability, and pulverizing speeds up;

3. screen frame increases side sieve sheet and following air inlet, makes the material that crushes in time from the discharging opening sucking-off, has improved output.

4. screen frame adopts two or some sieve sheets compositions, can reduce and change the screen cloth cost, sieves sheet as long as there is breakage monoblock to change slightly, as long as and that fritter that makes into will damage after several assemblings is changed in the past.

5. with plain bearing, change self-aligning bearing into, certain activity is arranged when making the rotor running, it is more flexible and steady to turn round, in the past per 1-2 months of bearing just wearing and tearing need to change, use self-aligning bearing instead after, can reach service life more than half a year, rotor, hammer leaf are improved running life.

6. reach more than 20% than common hammer crusher raising crush efficiency and output, save electric energy more than 20%.

Below in conjunction with accompanying drawing enforcement structure of the present utility model is described:

Fig. 1 is the internal structure schematic diagram of the utility model beater grinder;

Fig. 2 is the side view of Fig. 1;

Fig. 3 is mounted in the shape and structure figure of the helical teeth plate of pulverizing chamber upper box front portion;
