Description

A single roller pulverizer

Technical field:

The utility model belongs to the technical field of mechanical equipment for feed production and processing, in particular to a single-roller pulverizer.

Background technique:

The pulverizer is a machine that crushes large-sized solid raw materials to the required size. According to the roller shaft of the pulverizer, it can be divided into single-roll, double-roll and multi-roll pulverizers. At present, the most common type in the feed industry is the double-roll pulverizer. and multi-roll mills. For example, the publication number is CN102921494A, the name is "a kind of roller mill" and the publication number is CN202860613U, the name is "a Chinese patent of roller mill", and the disclosed roller mills are all a set of two rollers; The publication number is CN101367055, the name is "two groups of roller mills and its operating method", the publication number is CN201279473, the name is "two groups of roller mills" and the publication number is CN202490636U, and the name is "a new type of roller for food processing". The Chinese patent of "type pulverizer", the disclosed roller pulverizers are two sets of four-roll pulverizers; the Chinese patent with the publication number CN201279474 titled "three groups of roller pulverizers" discloses a kind of three groups of six-roll pulverizers Publication number is that CN101104151 name is called " roller mill " and publication number is that CN201291143 name is called " four groups of roller mills " and the disclosed roller mill is four groups of eight roller mills; And publication number is that CN102112230A name is "Roll Mill for Crushing Granular Materials" discloses a multi-roll mill. These double-roller and multi-roller pulverizers use the extrusion force generated by the relative rotation of one or more sets of independently driven roller shafts to crush materials. The roller body is a cylinder, and grooves are drawn on the cylindrical surface. The rollers are placed in parallel, and the circular surface is circumscribed. After the material enters the crushing chamber between the two rollers, the material is subjected to the tooth force of the drive roller, so that the material is forced to pass between the two rollers, and is squeezed, sheared and kneaded by the roller shaft at the same time. However, when the pellet feed passes through the double rollers, its force is more complicated, not only the downward squeezing force when the double rollers are rotary-cut, but also the upward resultant force when the two rollers rotate relative to each other. , This kind of complex force makes part of the pellet feed bounce, and part of the pellet material slips between the two rollers, which causes the friction and heat of the roller shaft, increases the energy consumption of the pulverizer, and the energy consumption per unit output is high.

Utility model content:

In summary, in order to overcome the deficiencies of the existing technical problems, the utility model provides a single-roller pulverizer, which is to set a friction roller in the casing of the pulverizer, and at the same time connect the casing to the friction roller. The corresponding part is designed as an arc tangent to the friction roller. The material to be crushed enters between the friction roller and the arc of the shell, and the material is crushed by the extrusion force between the friction roller and the arc of the shell. The single roller rotates, the structure is simple, and the material is subjected to a single force, which can effectively avoid the phenomenon of material slipping, reduce the calorific value of the friction roller, and save energy.

In order to solve the problems of the technologies described above, the technical solution of the utility model is achieved in this way:

A single-roller pulverizer, which includes a transmission device, a casing and a friction roller, the casing is provided with a feed port and a discharge port, the friction roller is arranged in the casing, and the transmission device drives the friction roller to rotate. The part of the shell corresponding to the friction roller is an arc-shaped plate, and the arc-shaped plate is inscribed with the friction roller.

Further, only cutting edges are provided on the outer circumference of the friction roller and on the inner side of the arc-shaped plate.

Further, the inner diameter of the arc-shaped plate is larger than the outer diameter of the friction roller.

Further, a deflector is provided on the feed inlet of the housing.

The beneficial effects of the utility model are:

1. In this utility model, a friction roller is installed in the casing of the pulverizer, and the part of the casing corresponding to the friction roller is designed as an arc tangent to the friction roller. The material to be crushed enters the friction roller and the casing. Between the arc-shaped parts of the body, the crushing force between the friction roller and the arc-shaped parts of the shell is used to crush the material. The single roller rotates, the structure is simple, and the material is subjected to a single force, which can effectively avoid the slipping of the material and reduce friction. The calorific value of the rollers saves energy.

2. The friction roller of the utility model cuts inwardly with the arc-shaped plate of the casing, and the angle formed by the tangent between the arc-shaped plate and the friction roller is small. Relatively simple, only the downward squeezing force, so it will not cause the bounce of the granular material, thereby avoiding the slipping phenomenon of the granular material between the friction roller and the arc plate, reducing friction and heating of the roller shaft, and reducing the unit output of the pulverizer energy consumption.
