RU155477U1 - ROTARY CRUSHER - Google Patents

Abstract

A rotor crusher, consisting of a stator housing and a drive rotor located in its cavity, a receiving, crushing, and unloading chambers, as well as a loading hopper connected to the receiving chamber, the inner surface of the stator and the rotor surface being corrugated with the possibility of crushing the initial product, characterized in that the rotor is made integral in the form of an inertial part rigidly connected to the physical axis of the rotor and worn on it with the possibility of temporarily securing a closed cylindrical shell, moreover, The inertial part of the rotor can be made either in the form of a cylinder, or in the form of separate disks with their location along the rotor axis, corresponding to the optimal placement of the supports of the continuous beam under the action of a uniformly distributed load.

Description

The technical field to which the utility model relates.

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

Known rotary crusher, consisting of a casing and a drive rotor located in its cavity, a crushing and unloading chambers and a feed 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. 2252075, B02C 13 / 06, published 05/20/2005).

The disadvantages of the known crusher include a metal-intensive casing, difficulties and inconvenience of transportation, the design of the rotor limits the possibility of its use.

Known rotary crusher, which includes a housing with loading and unloading chambers connected to the stator, a crushing chamber and a horizontally located rotor rigidly mounted on the shaft, while the interaction of the rotor and the working bodies of the crushing chamber allows crushing the source material (see patent RU No. 2073332, B02C 13/26, published 02/10/1997).

The disadvantage of this crusher is the high metal consumption of the structure with a large number of working elements in the cavity of the crusher, which reduces maintainability and complicates the cleaning of over-crushed (flour) fractions.

The closest in technical essence to the alleged invention is a rotary crusher, 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 the rotor being able to interact when crushing the initial product, and the rotor is rigidly fixed to the shaft (see patent RU No. 2396121, B02C 13/06, published on 08/10/2010).

The disadvantage of this crusher is its high metal consumption and low maintainability due to the design of the rotor connecting the rotor and the working surface in one element.

Utility Model Disclosure

A rotor crusher, consisting of a stator housing and a drive rotor located in its cavity, a receiving, crushing, unloading chambers, as well as a loading hopper connected to the receiving chamber, the inner surface of the stator and the rotor surface being corrugated with the possibility of crushing the initial product, and the rotor is made integral, in the form of an inertial part of a cylindrical shape rigidly connected to the physical axis of the rotor and put on it, with the possibility of temporary fixation, of a closed cylindrical shell with a reef enoy working surface, wherein the inertia rotor part may be formed as a cylinder, and in the form of individual disks with their location on the rotor shaft, corresponding to the optimal placement supports continuous beam under a uniformly distributed load.

A feature of the crusher is the composite rotor design, which includes a constant inertial axial part and a removable working part fixed to it. The possibility of replacing the working part allows you to adapt the crusher to various initial crushing products.

Utility Model Implementation

The rotor crusher 1 (Fig. 1) consists of a stator casing 2 and a drive rotor 3, a receiving 4, a crushing 5, an unloading 6 chambers, and also a loading hopper 7 connected to the receiving chamber, the inner surface of the stator 8 and the surface of the rotor 9 is made corrugated with the possibility of crushing the initial product, and the rotor 3 is made integral, in the form of a rigidly connected to the physical axis of the rotor 10 of the inertial part 11 and worn on it, with the possibility of temporary fastening by screws 12, a closed cylindrical shell and 13 with a working surface (Fig. 2), and the inertial part of the rotor can be made in the form of a cylinder 14 (Fig. 3) or in the form of separate disks 15 (Fig. 4) with their location along the axis of the rotor 10 corresponding to the optimal the placement of supports continuous beam under the action of a uniformly distributed load.

The placement of individual disks 15 on the physical axis of the rotor 10 corresponding to the position of the supports of the continuous beam under the action of a uniformly distributed load with the smallest bending moment is defined as the first approximation (according to the beam scheme) in the problem of optimal design of the placement of circular supports for the construction of a closed cylindrical shell.

The process of loading the original product, its transportation, processing into crushed material and its removal are shown by arrows. When the rotor rotates, the initial product interacts with the corrugated surfaces of the rotor and stator and is crushed.

The proposed utility model in comparison with the known technical solutions allows to reduce the material consumption of the machine and adapt the crusher to various initial crushing products, replacing, if necessary, the working surface of the rotor.
