Abstract

A material crusher comprises a casing; a material at the upper part of the casing; a crushing chamber at the middle part of the crushing chamber; rotators and hammering pieces in the crushing chamber; arc-shaped sieving pieces at the external circumference of the rotator; a material feed passage at the upper part of the crushing chamber; a wear-resistant steel plate at one side of the material feed passage; sieve pressing plates of the sieving pieces at two sides of the crushing chamber entrance; and a material exit at the lower part of the crushing chamber. The crusher is characterized in that the lower part of the wear-resistant steel plate has a middle retaining plate protruding inward with a 135 plus or minus 5 degree included angle; the front sieve pressing plate nearing the material feed passage has a front retaining plate forming a 150 plus or minus 5 degree included angle with the steering rotator; the lower part of the rear sieve pressing plate has a rear retaining plate forming a 160 plus or minus 5 degree included angle with the steering rotator. The utility model can break the material circumfluence layers in the crushing chamber; the blocking effect of the front, middle and rear retaining plates changes the material circumfluence direction; the material striking strength is enhanced due to the beating of the front and rear retaining plates, so the crushing efficiency is increased by 20 percent compared with prior crushers.

Description

Materials crusher
Technical field
The utility model relates to a kind of materials crusher.
Background technology
Existing pulverizer, its structure comprises casing, pulverizing chamber, pulverizing chamber is surrounded by the sieve sheet.Feed hopper is arranged at pulverizing chamber top, and feed hopper and pulverizing chamber junction one side are equipped with wearing plate; One rotor is arranged in the pulverizing chamber, hammer leaf is housed on the rotor.During the rotor rotation, material is smashed by hammer leaf.When material falls into the pulverizing chamber that the sieve sheet surrounds by the top hopper, smashed pulverizing the district, fall into the bottom by the smooth plate of sieve sheet then, under gravity or wind-force effect, through the discharging opening discharge body that will mince by the hammer leaf on the high speed rotor rotated.The material that is not smashed is fully made circulation movement at the effect lower edge of hammer leaf sieve sheet, forms circulation layer, takes body upper to after turning around with certain speed, and material upwards impacts, and the material that hinders in the hopper falls smoothly.Because the gap of pulverizing chamber porch and hammer leaf is bigger, the dynamics of hammer leaf strike material is little simultaneously, and most of power consumption is on the velocity of circulation that increases material, and circulation layer is difficult to destroy, and causes the energy consumption height, and efficient is low.
Summary of the invention
The purpose of this utility model is the circulation direction of appropriate change material, and a kind of good crushing effect, materials crusher that efficient is high are provided.
The purpose of this utility model is achieved by the following technical solution: materials crusher, comprise casing, the hopper on casing top, the pulverizing chamber at middle part, rotor in the pulverizing chamber, be installed in epitrochanterian hammer leaf, the lonely shape sieve sheet of rotor periphery, one feeding-passage is arranged at pulverizing chamber top, feeding-passage one side is provided with wear-resisting steel plate, the sieve sheet of both sides, pulverizing chamber porch is equipped with the pressure sieve plate, one discharging opening is arranged at the pulverizing chamber bottom, it is characterized in that the middle baffle plate of 135 ± 5 ° of angles of one-tenth of inwardly giving prominence to is arranged at the wear-resisting steel plate bottom, the preceding sieve plate of pressing has the front apron that turns to 150 ± 5 ° of angles of one-tenth of rotor by the feeding-passage place, the back presses the sieve plate bottom that the backboard that turns to 160 ± 5 ° of angles of one-tenth of rotor is arranged, and is preceding, the length of backboard and hammer leaf keep certain interval.
The more conventional pulverizer of the utility model, has following good effect: 1, can destroy the material circulation layer in the pulverizing chamber, when material is thrown to the pulverizing chamber top, because stopping of front apron, middle baffle plate, backboard, not only material circulation direction changes, and be subjected to the strike of front and rear baffle, and increasing the intensity that material is hit, crushing effect improves; 2, the crush efficiency height cuts down the consumption of energy, and is higher by 20% than original pulverizer efficient.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
Figure 1 shows that the utility model materials crusher, comprise casing, hopper 8, pulverizing chamber 5, be positioned at pulverizing chamber rotor 4, be installed in the lonely shape sieve sheet 2 of epitrochanterian hammer leaf 3, rotor periphery, pulverizing chamber top has a feeding-passage to connect hopper 8, and a discharging opening 1 is arranged at the pulverizing chamber bottom.Feeding-passage one side is provided with wear-resisting steel plate 6, the sieve sheet of both sides, pulverizing chamber 5 porch respectively is equipped with one presses sieve plate 7, the middle baffle plate 10 of one 135 ± 5 ° of angles of one-tenth of inwardly giving prominence to is arranged at wear-resisting steel plate 6 bottoms, the preceding sieve plate 7 of pressing has the front apron 9 that turns to outstanding 150 ± 5 ° of angles of one-tenth, and the back presses sieve plate 7 that the backboard 11 that turns to 160 ± 5 ° of angles of one-tenth of giving prominence to is arranged.
The course of work: material falls into pulverizing chamber 5 by hopper 8, material is hit once by epitrochanterian hammer leaf 3, throw to the top of pulverizing chamber 5 then, being subjected to stopping of front apron 9 is folded to wearing plate 6, material in the hopper 8 continues to fall, the material of circulation and the mixing of materials that falls because middle baffle plate 10 has been controlled the strike gap, make the strike of 3 pairs of materials of hammer leaf stronger.Material is thrown on the backboard 11 after middle baffle plate place is hit, and this moment, hammer leaf 3 can carry out second strike to material, so went round and began again, and had improved strike effect.Material after the pulverizing falls into organism bottom by sieve sheet 2 under the effect of gravity or wind-force, discharge from discharging opening 1.
Press sieve plate 7 and front apron 9 (pressing sieve plate 7 and backboard 11) to be formed by two plate welding or a plate bending, wear-resisting steel plate 6 can be formed by two plate welding or a plate bending with middle baffle plate.
