Description

A closed mechanical crushing device for biomass feed

technical field

The utility model relates to the technical field of biomass feed processing, in particular to a closed mechanical crushing device for biomass feed.

Background technique

The crushing of feed raw materials is a very important link in feed processing. Through crushing, the large total surface area of raw material particles per unit mass can be increased, the solubility of feed nutrients in animal digestive juice can be increased, and the digestibility of animals can be improved; at the same time, the particle size of raw materials can be crushed. The small size has a very important impact on the difficulty of subsequent processes (such as granulation, etc.) and the quality of finished products; moreover, the size of the crushed particle size directly affects the production cost. When producing powdery compound feed, the power consumption of the crushing process About 50% to 70% of the total power consumption. The smaller the crushing particle size, the more conducive to animal digestion and absorption, and the more conducive to granulation, but at the same time the power consumption will increase accordingly, and vice versa. Therefore, how to make the crushed particles small and consume less energy has become a problem in the prior art; at the same time, due to the structural constraints of the casing, the material will move randomly in the cavity of the casing during the crushing process, making it impossible for the blade to grind in time. The material is crushed, resulting in uneven crushing of the material.

For this reason, Chinese patent CN205042572U discloses a pulverizer, which includes a frame, a casing arranged on the frame, a main shaft that penetrates through the casing and is connected to the left and right end surfaces of the casing through bearings, and the The main shaft is connected to a motor that provides power, the upper end surface of the chassis is provided with a feed port, and the lower end surface is inclined with a bottom plate. Circular tube structure, with at least two cutting knives on the same circumference, the material enters the casing from the feed port, and falls from one end of the casing to the other end due to gravity, during the falling process, the cutting knives cut the material Multi-cutting; the shape of the utility model box limits the splashing space of the material in the box, which can make the material fully crushed in a small crushing space and improve the crushing effect of the pulverizer. At the same time, the bottom wall of the box is a filter. , the crushed material can be screened to make the material fully crushed; however, in the actual application process, the utility model cannot effectively sort the discharged material, so that the crushing effect cannot be reflected, and needs to be improved urgently.

In order to achieve the above object, the utility model provides the following technical solutions:

A closed-type mechanical crushing device for biomass feed, comprising a frame, a casing arranged on the frame, a main shaft penetrating through the casing and connected to the left and right end faces of the casing through bearings, and the main shaft and the main shaft A driving device that is connected and provides power. The upper end surface of the chassis is provided with a feed port, and the lower end surface is provided with a bottom plate inclined. The knife holder is a circular tube structure, and at least two cutting knives are arranged on the same circumference, and the length of the cutting knives gradually decreases from the highest point to the lowest point of the bottom plate; In the screening grid area, there are mutually independent feeding channels under each screening grid area, and the lower part of the feeding channel is connected to the trough; the lower end of the receiving trough corresponding to the bottom of the bottom plate is provided with a recovery cylinder, and the recovery cylinder The bottom end is connected with a conveying auger, the output end of the conveying auger is connected with a bucket elevator, and the upper end of the bucket elevator communicates with the feed inlet.

As a further technical solution of the present invention, the longitudinal section of the cabinet is a trapezoidal structure, the upper and lower bottoms of which are vertically arranged, and the feed inlet is arranged on a side close to the upper bottom.

As a further technical solution of the utility model, a material receiving box is arranged below the cabinet.

As a further technical solution of the utility model, the inclination of the bottom plate is 10-20°, and the bottom plate is also connected with a bin wall vibrator.

Compared with the prior art, when the utility model is working, the material enters the casing from the feed port, and due to gravity, it falls from one end of the casing to the other end. During the falling process, the cutting knife cuts the material multiple times. At the same time, the shape of the case limits the splashing space of the material in the case, so that the material can be fully crushed in a small crushing space, and the crushing effect of the pulverizer is improved. The material is screened to make the material fully crushed. The crushed material is classified and screened under the screening effect of the bottom plate. On the one hand, it avoids the situation of discharge blockage, and on the other hand, the unbroken material can be recycled in time for secondary crushing. , which improves the quality of material crushing and also enables feed to be classified according to different qualities, which improves economic benefits.
