Background

The pulverizer is a machine for pulverizing a large-sized solid raw material to a desired size, and pulverizing of the raw material is performed by using the pulverizer in many industries. Common crushers include vertical crushers, horizontal crushers, and cage crushers. The water content of animal manure (such as chicken manure and cow manure) is up to 30-90%, and the existing pulverizer is used for pulverizing high-humidity high-fiber raw materials in a single time, and the granularity after pulverization can not meet the granulating requirement (more than 50 meshes). In addition, the high-humidity high-fiber raw material is easy to be stuck in the wall of the crushing cylinder in the crushing process, and needs to be cleaned periodically. In addition, there is a problem that fine powder cannot be discharged in time and repeatedly pulverized.

Due to the implementation of the technical scheme, compared with the prior art, the utility model has the following technical effects: in the utility model, two sets of rotors which are connected in the same direction are adopted, so that the materials which are broken and hit by the upper rotor are broken and broken again by the lower rotor which rotates at high speed, and the materials are mutually collided and broken. The water content of the materials is not strictly required, the problems that the sieve plate is blocked by paste and fine powder cannot be discharged in time and repeatedly crushed are avoided, and the crushing efficiency is high.

Further, a feed return prevention plate is additionally arranged in the feed inlet, so that the raw materials scattered and splashed at high speed in the crushing bin are prevented from obstructing the input of the subsequent raw materials, and the feed process is smoother and more orderly.

Furthermore, the alloy high-wear-resistance blade or hammer head is adopted, and only the blade is replaced by daily wear without replacing the cutter bar.

Further, the inner wall of the crushing bin is provided with a detachable and replaceable lining plate, and the inner lining plate can be quickly replaced when the inner lining plate is worn.

Further, the machine body is provided with a closed access hole, and daily maintenance is simple and quick.

Detailed Description

The technical scheme of the utility model is described in detail through specific examples.

As shown in fig. 1 to 2, the twin-stage wet pulverizer includes a frame 1, and an upper pulverizing bin 5 and a lower pulverizing bin 6 which are staggered and communicated up and down are fixed to the frame 1, that is, the upper pulverizing bin 5 is above the side of the lower pulverizing bin 6. The top of the upper crushing bin 5 is provided with a feed inlet 2, the bottom of the lower crushing bin 6 is provided with a discharge outlet 3, the upper crushing bin 5 and the lower crushing bin 6 are respectively provided with an upper rotor and a lower rotor, the rotation directions of the upper rotor and the lower rotor are the same, and the outer circles of the upper rotor and the lower rotor are connected, so that materials crushed by the upper rotor enter the lower rotor from the communication position of the upper crushing bin 5 and the lower crushing bin 6.

In this embodiment, the feed inlet 2 is inclined, and its inclination is unanimous with the inclination of the central line of upper and lower rotor, is equipped with in the feed inlet 2 and prevents returning charge board 4, prevents returning charge board 4 and articulates in frame 1, prevents returning charge board 4 at the natural suspension and the contained angle of feed inlet 2 axis be the acute angle for prevent returning charge board 4 can be stopped by the lateral wall of feed inlet when returning charge appears. The upper rotor and the lower rotor are respectively detachably provided with an alloy high-wear-resistance blade or hammer head through a cutter bar, and the blade and the cutter bar are fixed and combined through bolts. The upper rotor and the lower rotor are connected with the frame 1 through a first bearing seat 7 and a second bearing seat 8 respectively, and are driven by a first motor 9 and a second motor 10 through belt pulleys respectively.
