Referring to fig. 1-6, a pulverizing device for granulating pulverized coal ash includes a housing 1, the housing 1 is a rectangular structure and is vertically arranged; the upper side of the shell 1 is provided with a feeding port in an opening mode, and the lower side of the shell 1 is provided with a discharging port.

The interior of the shell 1 is provided with a material homogenizing part 2, an inclined screen grinding part 3 and a grinding assembly 4 from top to bottom.

Wherein, the feed material is uniformly dispersed by the material homogenizing part 2.

Specifically, the refining element 2 is a vibrating screen and is horizontally arranged inside the shell 1.

The feed material enters the shell 1 from the upper part and is gathered on the refining part 2; under the action of the vibrating screen, the materials are uniformly dispersed and fall, so that the phenomena of mass accumulation and blocking are avoided; so that the lower material is dispersed uniformly and the treatment is ensured to be continuous and stable.

The inclined screen grinding part 3 carries out multi-stage screening and grinding on the fed materials.

Through the screening process, materials with different volumes are processed in different levels, and stable quality and high consistency of quality of discharged materials are further ensured.

Specifically, the inclined screen grinding component 3 consists of an inclined screen 5 and a grinding assembly 6.

Wherein, one side of the inclined screen 5 is arranged in a downward inclination way; one side of the high end of the inclined screen 5 is fixedly connected with the inner wall of the shell 1, and one side of the low end of the inclined screen 5 is spaced from the inner wall of the shell 1; in addition, the two sides are fixedly connected with the inner wall of the shell 1, so that the stability and reliability of the installation state are ensured.

Accordingly, the grinding assembly 6 is disposed at a lower end side of the inclined screen 5.

Therefore, the materials which can pass through the inclined screen 5 directly fall, and the rest screened materials slide down to the lower end side through the upper surface of the inclined screen 5 and enter the grinding assembly 6 for processing.

Further, the inclined screen grinding component 3 is provided with at least two groups of inclined screens 5 and grinding components 6; wherein the high end of the lower inclined screen 5 is positioned at the lower end of the upper grinding assembly 6.

Meanwhile, the aperture of the inclined screen 5 of the upper and lower layers is gradually reduced from top to bottom.

After being screened by the upper inclined screen 5 or being processed by the grinding component 6, the materials enter the next inclined screen 5 for secondary screening and processing.

Through setting up to multistage, to the material of different volumes through the shredding of different numbers of times to save unnecessary grinding consumption, and fully guarantee the treatment effect.

In some embodiments, the grinding assembly 6 is composed of a first roller 601 and a second roller 602.

Wherein, the first roller 601 and the second roller 602 are matched; the material enters between the first roller 601 and the second roller 602, and is rolled and crushed.

Further, the outer surfaces of the first rolling roller 601 and the second rolling roller 602 are provided with grooves 603; thereby forming a groove ring and a convex ring on the outer surface.

Correspondingly, the grooves 603 of the first grinding roller 601 and the second grinding roller 602 are arranged in a staggered manner, and the convex parts of the first grinding roller 601 are clamped into the grooves 603 of the second grinding roller 602.

During processing, the material enters the groove 603 of one roller and is rolled by the convex part of the other roller; the two side walls of the groove are limited and blocked, so that the treatment effect is further ensured.

In some embodiments, one end of the first roller 601 and the second roller 602 is provided with a gear 604 engaged with each other; the gear 604 is in transmission connection with a first drive motor 605.

The first driving motor 605 transmits to the gear 604 of one roller, and the gear 604 of the roller transmits to the gear 604 of the other roller; thus, the two rollers are made to rotate in opposite directions.

By controlling the direction of the first driving motor 605, the first roller 601 and the second roller 602 are close to one side of the inclined screen 5, and the feeding material is pulled into the first roller 601 and the second roller 602; that is, the direction of movement of the intersection point of the two is toward the outside of the housing 1.

The milling assembly 4 finely grinds the feed material.

Specifically, the milling assembly 4 is provided with a plurality of first horizontally arranged milling shafts 401.

The outer surfaces of the adjacent first grinding mill shafts 401 are provided with a spacing distance according to the set material processing accuracy.

After being processed by the inclined screen grinding component 3, the materials enter the grinding component 4; the polishing process is performed again by the first mill grinding shaft 401.

Further, the rotation directions of two adjacent first mill shafts 401 are opposite.

Thereby avoiding the mutual interference caused by that one throws the material upwards and the other sends the material downwards at the adjacent positions.

A second driving motor 404 is arranged outside the housing 1, and a double-groove belt pulley 4011 is arranged at one end of the first grinding and milling shaft 401; the second driving motor 404 is drivingly connected to the two spaced first mill shafts 401.

Thus, one second driving motor 404 drives two first grinding mill shafts 401 to make the running directions of the two first grinding mill shafts consistent; the other of the two first grinding shafts 401 is driven by the other second driving motor 404, and the rotation directions are set to be opposite.

Meanwhile, the double-groove belt pulley 4011 is matched to stagger the transmission belts of the first grinding and milling shafts 401, so that crossing and interference are avoided.

Further, in some embodiments, the milling assembly 4 is provided with a plurality of horizontally arranged second mill shafts 402; so as to further ensure the grinding and fine processing effect.

Meanwhile, a second mill shaft 402 is arranged at the lower part of the first mill shaft 401, and the second mill shaft 402 is in transmission connection with the first mill shaft 401 through a belt 403; no other power input is needed.

When the utility model is used, materials are added from the upper part; the materials are uniformly dispersed under the action of the material homogenizing part 2 and fall onto the first-stage inclined sieve 5 at the lower side; the materials which can pass through the inclined screen 5 directly fall, and the rest materials obliquely slide into the grinding assembly 6 for grinding treatment; the material after the primary crushing treatment is sieved again by the next-stage inclined sieve 5 to directly pass through or enter the next-stage grinding assembly 6; after multi-stage screening and treatment, the mixture enters a grinding component 4 for fine grinding; after the powder is processed, the powder is discharged through the outlet on the lower side.
