Abstract

FIELD: machine building.

SUBSTANCE: crusher comprises a casing on a supporting element (3) with shock absorbers (4) and a loading hopper. A drive rotor (6), loading (7), crushing (8) and unloading (9) chambers are installed in the casing cavity. The crushing chamber and the rotor are fitted by corrugated surfaces (10, 11). The casing comprises load-carrying part from steel and enclosing part (13) from plastics or fabric. The enclosing part can be insulated from the environment. The load-carrying part of the casing is presented by its ends. The ends are made from two coaxially set parallel flat disks with axial holes. The disks are rigidly connected to the circular rims outside. The rotor is installed between the disks. The rotor axis is fixed in the holes at the flat disks and can rotate. The rims are fixed at the supporting element and are symmetrically interconnected by longitudinal elements (20, 21) with the corrugated surfaces turned inwards. The rims interact with the corrugated surface of the rotor at crushing. The position of the rims is adjustable to a limited extent on the surface of the circular rim and in radial direction. The crusher cavity provides for the removal of dusty fractions by suction.

EFFECT: improved reliability and efficiency of device operation, simplified replacement of working members and their installation.

Description

FIELD OF THE INVENTION

Rotary crusher refers to devices for grinding bulk product and can be used in the food industry or in feed production.

State of the art

A rotary crusher is known, consisting of a housing and a drive rotor located in its cavity, a crushing and unloading chambers and a loading hopper connected to the stator, the crushing chamber and rotor being made with the possibility of interaction when crushing the initial product (see patent RU No. 2205694, B02C 13 / 06, published 06/10/2003).

The disadvantages of such a rotary crusher include the fact that the design does not have the ability to control the position of the working elements, and this limits its functionality and versatility.

Known rotary crusher, which includes a housing with a loading and unloading chamber, a horizontally located rotor with beater mounted on it, while the interaction of the rotor and the working bodies of the crushing chamber allows crushing the source material (see patent RU No. 2396121, B02C 13/06, published 10.08 .2010).

The disadvantage of this crusher is the increased metal consumption of the structure and a large number of working elements in the cavity of the crusher, which complicates the replaceability of the elements, cleaning them from over-crushed (flour) fractions. At the same time, a large metal-intensive housing is difficult and inconvenient to transport.

The closest in technical essence and the achieved positive effect and adopted by the authors for the prototype is a feed crusher, consisting of a housing and a drive rotor placed in its cavity, a crushing and unloading chambers and a loading hopper connected to the stator, and the crushing chamber and rotor are designed to interact with crushing of the original product (see patent RU No. 2105609, B02C 13/06, published on 02.27.1998).

The disadvantage of this crusher is the inability to regulate the gap in the interaction of the rotor with the stator. At the same time, the crusher has a one-piece metal casing having a high metal consumption and making it difficult to replace its working elements.

Disclosure of invention

The technical result is achieved by eliminating the noted drawbacks using a rotary crusher consisting of a housing mounted on a support element with shock absorbing gaskets, a loading hopper and loading, crushing and unloading chambers located in the cavity of the drive rotor housing, while the crushing chamber and rotor are provided with corrugated surfaces made with the possibility of crushing the initial product, the rotor crusher body consists of two structural parts - a bearing made, for example, of steel and a barrier made, for example, of plastic or fabric, the bearing part of the body being its ends made of two coaxially arranged parallel flat disks with axial holes rigidly connected outwardly with ring rims fixed to the supporting element, and the drive rotor is placed between the flat disks with the fixing of its axis in the holes of the flat disks with the possibility of rotation, and the annular rims are symmetrically connected to each other by longitudinal elements with corrugated surfaces inward, uyuschimi with grooved rotor surface when crushing a starting material, adapted to limited adjustment of position on the surface of the annular rim, and in the direction of its radius, wherein the crusher cavity is configured to remove dust fractions produced during the fragmentation, by suction.

The rotary crusher is easy to assemble and disassemble, the least metal consuming, allows you to adjust the position of the longitudinal elements with grooved surfaces in two directions to increase its efficiency and remove dust fractions from the cavity of the crusher without stopping its operation.

The implementation of the invention

Rotor crusher 1 consists of a housing 2 mounted on a supporting element 3 with shock absorbing gaskets 4, a loading hopper 5 and placed in the cavity of the housing of the drive rotor 6, loading 7, crushing 8 and unloading 9 chambers, while the crushing chamber 8 and rotor 6 are equipped with corrugated surfaces 10 and 11, respectively, made with the possibility of crushing the initial product, and the housing 2 of the rotor crusher 1 consists of two structural parts - the carrier 12, made, for example, of steel, and enclosing 13, made, for example, of plastic or fabric, and the bearing part of the case is its ends made of two coaxially placed parallel flat disks 14 with axial holes rigidly connected outwardly with the ring rims 15, bolted 16 in the groove 17 of the support element 3, and the drive rotor 6 is placed between the flat the disks 14 and the placement of its axis 18 in the bushings 19 of the flat disks 14, and the annular rims 15 are symmetrically interconnected by longitudinal elements 20 and 21, increasing the rigidity of the structure and provided with corrugated surfaces 10 inward, interacting with the corrugated surface of the rotor 11 during crushing of the initial product, made with the possibility of limited regulation of their position both on the surface of the annular rim 15 by moving the longitudinal element 20 in the elliptical slot 22 and securing it with bolts 23, and in the radial direction by installing washers 24, and in the supporting element of the cavity of the crusher, an opening is made with a nozzle 25 fixed in it, with the possibility of connection with a hose 26 of a dust extraction device, for example a vacuum cleaner.

The process of loading the original product, its transportation, processing into crushed material and its removal are shown by arrows. When the rotor 6 is rotated clockwise, as shown in FIG. 5, which interacts with the corrugated surface 11 of the rotor 6 and crushes the initial product, is a longitudinal element 20 with a corrugated surface 10. When the corrugated surface is worn in the longitudinal element 20, it is replaced by the longitudinal element 21, and is installed in its place.

The invention in comparison with the prototype and other known technical solutions has the following advantages:

- increases the reliability of the crusher;

- provides control of the process of crushing the material by adjusting the position of the longitudinal element with a corrugated surface, which increases the efficiency of its work;

- the design of the crusher allows its transportation in a compact disassembled form;

- makes it possible to remove dusty, flour fractions during the operation of the crusher;

- simplifies the interchangeability of the working bodies and their adjustment to achieve the best result.
