Abstract

The utility model discloses a coal crusher. The downward side of a feeding hopper(5) of the crusher is provided with a spiral transportation machine(6); a feeding mouth(41) is arranged at the lower side part of a crushing cabinet(4) and a feed outlet(42) is arranged at the upper side part of the crushing cabinet(4); the feeding mouth(41) and the feed outlet(42) are arranged at the relative positions on the circumference of the crushing cabinet(4); the feed outlet(42) is externally provided with an inverse U shape pinch plate that is arranged along a parabola curve. The utility model has stable feed current so as to be uneasy to burn the motor, small powder dust pollution, small production noise, and safe use, which can be used for crushing the dry and wet feeds such as coal and lime and so on; the feeding can reach 10cm and the crushing granularity is 1.2 to 0.5mm; when used for coal processing, the utility model can once make the coal and soil into feed.

Description

Coal pulverizer

Technical field:

The utility model relates to a kind of coal and pulverizes process equipment, especially a kind of hammering type pulverizer.

Background technology:

Existing coal pulverizer tool is varied, and wherein the charging aperture of hammering type pulverizer is positioned at the top of pulverizing the storehouse, because coal is to rely on the gravity of self to enter the pulverizing storehouse, charging is wayward, and when coal was dry, charging was easily many, often make the motor overload running, when coal is wet, cause obstruction again easily, can't operate as normal, like this, the wet instability of situation, materials flow of the different dry of coal causes the operating current instability of motor, burns motor easily.In addition, the discharging opening of pulverizer is positioned at the bottom of pulverizing the storehouse, broken good coal dust from discharging opening linearly level throw away, fall, discharge disperses, coal dust heap Chang Keda 3-4 rice, floor space is big, dust pollution is serious, flies out in case wherein be mingled with metal object, hurts sb.'s feelings easily, dangerous, and it is also bigger to produce noise.

Summary of the invention:

The purpose of this utility model is to provide a kind of materials flow of charging stable, dust pollution is little, produce noise coal pulverizer little, safe in utilization.

The concrete technical scheme that the utility model adopts is: it comprises motor, belt pulley, weight, pulverizing storehouse, feed hopper, pulverizer feed hopper below is provided with conveying worm, the output of conveying worm links to each other with the charging aperture of pulverizing the storehouse, charging aperture is located at pulverizes the following side, storehouse, discharging opening is located at the upper lateral part of pulverizing the storehouse, and charging aperture and discharging opening are positioned at the relative position of pulverizing on the circumference of storehouse, and discharging opening is provided with " U " buckle of curve setting parabolically outward.

As a kind of improvement of the present utility model, to pulverize and be provided with air inlet on the storehouse around the weight axis hole, the bearing block of weight axle and pulverizing storehouse are at intervals.

As another kind of improvement the of the present utility model, a side relative with belt pulley on the weight axle is provided with stabilizer.

Because the utility model adopts the conveying worm charging, the coal of doing, wet all can be produced, and materials flow is stable, so the operating current of motor is stable, is difficult for burning motor.Because being located at, charging aperture pulverizes the bottom, storehouse, discharging opening is located at the upper lateral part of pulverizing the storehouse, coal cinder enters from the bottom pulverizes the storehouse, after the weight pulverizing that runs up, throw away from discharging opening along parabolic curve, then stopped and fall by buckle, therefore discharge concentrates on the buckle below, simultaneously because coal dust is up and along the buckle whereabouts that moves ahead along parabola, and these coal dusts have formed the barrier layer, the sound that stops in the storehouse leaks, reduced noise effectively, stop that also the coal dust in the storehouse leaks, reduced pollution effectively, use also safer.In addition, be provided with air inlet on every side owing to pulverize the weight axis hole in storehouse, wind enters outside the storehouse in the storehouse, has played the effect of noise reduction, has further reduced noise.The bearing block of weight axle and pulverizing storehouse at intervals avoid dust to enter bearing, have protected bearing.Because a side relative with belt pulley is provided with stabilizer, energy saving on the weight axle.

Description of drawings:

Fig. 2 is the utility model schematic top plan view.

The specific embodiment:

As shown in Figure 1, the utility model coal pulverizer, comprise motor 1, belt pulley 31, weight 3, pulverize storehouse 4, feed hopper 5, weight axle 2 is fixed on the frame 10 by bearing block 21, motor 1 provides power for weight axle 2 by belt pulley 31, pulverizer feed hopper 5 belows are provided with conveying worm 6, conveying worm 6 provides power by another belt pulley 71 on the weight axle 2 by reductor 7, the output of conveying worm 6 links to each other with the charging aperture 41 of pulverizing the storehouse, charging aperture 41 is in the following side of pulverizing storehouse 4, discharging opening 42 is at the upper lateral part of pulverizing storehouse 4, and charging aperture 41 is positioned at relative position on 4 circumference of pulverizing storehouse with discharging opening 42, like this, four quadrants pulverizing on 4 circumference of storehouse just are divided into feed position successively, pulverize the position, go out material level and position, space, broken good coal dust 42 throws away along parabolic curve from discharging opening, discharging opening 42 outside on button " U " buckle 8, the coal dust that throws away is stopped by buckle 8 and falls.In addition, can offer air inlet on the bulkhead around weight axle 2 holes of pulverizing storehouse 4, air inlet can be set as four, upper and lowerly relatively respectively open a gap, left and rightly relatively respectively open an angle, the bearing block 21 of weight axle 2 with pulverize storehouse 4 at intervals, get out of the way the air channel and be beneficial to air intake.Weight axle 2 should adapt with the rotating speed of conveying worm 6, the rotating speed of conveying worm 6 is too high, feeding is too much, coal does not reach to pulverize fully and promptly throws away, and influences crushing effect, and the rotating speed of conveying worm 6 is low excessively, feeding is very few, the pulverizer material of not haveing enough to eat, waste electric power, the rotating speed of 1700～1800 rev/mins of weight axle 2 rotating speeds, conveying worm 6 is advisable for 11～17 rev/mins.For utilizing energy better, save electric power, opposite side relative with belt pulley 21 on weight axle 2 can be provided with stabilizer 9, and promptly inertia gets rid of wheel, and stabilizer 9 is enclosed within on the weight axle 2, the whipping along with the running of weight axle 2.The utility model can be used for dried wet stocks such as comminuted coal, lime, and charging can reach 10 centimetres, and grinding particle size can reach 1.2～0.5 millimeters, is used for coal and adds man-hour, coal, soil once can be become material.
