Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.

Referring to fig. 1, in the preferred embodiment of a pulverizing device, the pulverizing device includes a frame 1, a case 2 is fixedly disposed on the frame 1, a feeding hopper 3 is disposed on the top of the case 2, a discharging port 4 is disposed on the bottom of the case 2, the discharging port 4 is provided with a corresponding screen 5, the screen 5 is a foldable elastic screen, and can be put in or taken out from the discharging port 4, so that it can be replaced according to different requirements.

The machine case 2 comprises an upper pretreatment chamber 6 and a lower crushing chamber 9, a first crushing roller set 7 and a second crushing roller set 8 are arranged in the pretreatment chamber 6, the second crushing roller set 8 is positioned at the bottom of the first crushing roller set 7, the first crushing roller set 7 and the second crushing roller set 8 both comprise two crushing rollers rotating in opposite directions, the first crushing roller set 7 and the second crushing roller set 8 are used for primarily crushing raw materials, the raw materials are crushed to a given degree, the diameter of the crushing rollers in the first crushing roller set 7 is larger than that of the crushing rollers in the second crushing roller set 8, the gap between the rollers on the first crushing roller set 7 is larger than that of the rollers on the second crushing roller set 8, and the sharpness of the rollers on the second crushing roller set 8 is larger than that of the rollers on the first crushing roller set 7, therefore, the progressive crushing effect can be achieved in the pretreatment process.

The crushing chamber 9 is communicated with the pretreatment chamber 6, a first crushing mechanism and a second crushing mechanism are horizontally arranged in the crushing chamber 9, wherein the first crushing mechanism comprises a U-shaped crushing shaft 13, the U-shaped crushing shaft 13 penetrates through the side wall of the crushing chamber 9 and is connected with a first motor 14, the second crushing mechanism comprises a strip-shaped crushing shaft 11, the strip-shaped crushing shaft 11 is arranged in an opening of the U-shaped crushing shaft 13, the strip-shaped crushing shaft 11 penetrates through the side wall of the crushing chamber 9 and is connected with a second motor 10, the second motor 10 and the first motor 14 are both fixed on the frame 1 and are arranged oppositely, blades 12 which are fixedly connected and evenly distributed are arranged on the U-shaped crushing shaft 13 and the strip-shaped crushing shaft 11, the rotating directions of the U-shaped crushing shaft 13 and the strip-shaped crushing shaft 11 are opposite, therefore, in the operation process, raw materials which are primarily crushed by the crushing chamber 6 enter the crushing chamber 9 to be crushed, the U-shaped crushing shaft 13 rotates and drives the raw materials to rotate in the same, because the rotation directions of the U-shaped crushing shaft 13 and the strip-shaped crushing shaft 11 are opposite, the strip-shaped crushing shaft 11 rotates reversely to disorder the ordered movement so as to perform more sufficient chopping, the chopping efficiency is effectively improved, and the crushing sufficiency is ensured, and because the pretreatment chamber 6 performs primary crushing treatment on the raw material, overlarge or excessively hard raw material particles are prevented from directly contacting with the blade on the crushing mechanism, a good blade protecting effect is achieved, the service life of the blade is effectively prolonged, and because the particle sizes of the raw material after pretreatment are basically the same, the phenomena that the single or a plurality of larger particles are repeatedly crushed to the ideal size when the ordinary crusher is operated in the crushing chamber 9, the whole crushing time is prolonged, the size of the crushed particles is uneven and the like can be reduced.

In this embodiment, two opposite sides in upper portion of feeder hopper 3 are provided with

water inlet

15, 15 slant under shed settings of water inlet, water inlet 15 and outside high-pressure hot water union coupling, two opposite sides in upper portion of feeder hopper 3 still are provided with

air intake
