Embodiment 1

[0024] A screenless double-rotor pulverizer, comprising: an inlet 1, a distributing device 2, an air outlet, a shell 5, upper and lower lining plates, a rotor 10, a discharge port 13, a shock absorber 14, a base 15, in which , The base 15 is mounted on the shock absorber 14, the housing 5 is mounted on the base 15, the upper end of the housing 5 is provided with an inlet 1, the distribution device 2 is installed at the inlet 1, and the upper part of the housing 5 The sides are respectively provided with air outlets. Two crushing chambers 16 are formed by the arc shell 12 in the lower part of the shell and the edges of the upper liner 8 and the lower liner 18 inside the shell 5. The rotor is equipped with a hammer 11 10 is installed in the pulverizing chamber 16. The lower end of the pulverizing chamber 16 is a discharge port 13. The inner wall of the housing 5 with the same horizontal plane as the top of the upper liner 8 is equipped with a partition 21. The angle between the pa...

Embodiment 2

[0032] The crusher is fed evenly by a star distributor. When feeding from the left, open the upper right air supply port 3 and the left lower air supply port 20, the side cover 7 rotates to the right, the two rotors 10 rotate clockwise, the rotors 10 The linear speed of rotation is 100 m / s. The material moves from left to right under the impact of the hammer 11, and enters the crushing area on the left. When it reaches the center area, it forms a bottom-up movement direction. The material is hit from the top-down direction to form a strong hit with double linear speed, which instantly changes the direction of movement and enters the crushing area of ​​the right tooth plate from top to bottom, and then discharges through the discharge port 13.

Embodiment 3

[0034] The crusher is fed evenly by a star distributor. When feeding from the right side, open the left upper air supply port 19 and the right lower air supply port 6, the side cover 7 rotates to the left, and the two rotors 10 rotate counterclockwise. 10 The linear speed of rotation is 100 m / s. The material moves from right to left by the impact of the hammer 11 and enters the crushing area on the right. When it reaches the central area, it forms a bottom-up movement direction. The material is hit from the top-down direction to form a strong hit with double linear speed, which instantly changes the direction of movement and enters the crushing area of ​​the right tooth plate from top to bottom, and then discharges through the discharge port 13.

[0035] The sieveless double-rotor pulverizer of the present invention solves the situation that the bark cannot be reused and left to decay, reduces pollution emissions, is green, energy-saving, and environmentally friendly; a further ad...

Abstract

The invention relates to a screen-free double-rotor grinder. The grinder comprises a material inlet, a material distributing device, air supply outlets, a shell body, an upper liner plate, a lower liner plate, rotors, and a material outlet; the material distributing device is arranged on the material inlet, two sides of the upper part of the shell body are both provided with an air supply outlet, the arc outer shell of the mid-lower part of the shell body and the edges of the upper liner plate and the lower liner plate in the shell body cooperatively form two grinding chambers; rotors provided with hammering blades are arranged in the grinding chambers; the material outlet is arranged in the lower end of the grinding chambers, and a partition plate is arranged on a position on the inner wall of the shell body, wherein the position of the partition plate is in the same level as the top part of the upper liner plate. The screen-free double-rotor grinder can grind barks into flocculent substance, fluffy substance, granules, or bagasse-like stuffs, and has the advantages of simplicity and high efficiency.

Description

Technical field [0001] The invention relates to a screenless double-rotor pulverizer. Background technique [0002] Guangxi has a high yield of eucalyptus, and the bark produced by the peeling veneer factory is very large. Because it is difficult to reuse, some manufacturers even dispose of it at will, without charging at all, and letting it rot, so the bark price in Guangxi is very low. It is very economical to use this cheap bark as fuel to supply paper mills and sugar mills. [0003] However, currently there are few pulverizers for bark in the market, and the effect is not ideal when a large amount of bark is pulverized into flocs, velvet, or granules similar to bagasse. [0004] The inventor once applied for a sieveless double-rotor pulverizer with application number 201320593850.8. The pulverizer still has some problems of not pulverizing because the flow of incoming raw materials is too large and too fast. Summary of the invention [0005] In order to overcome the defects of t...
