Abstract

The utility model relates to a breaker used in building material industry. Two sets of breaking rotors which rotate in different speeds and in opposite directions are arranged in the cabinet, and a scraping cutter frame for clearing the clay between cutter blades and an anti-sticking chain are additionally arranged in the cabinet. The utility model has the advantages that the material size is large, the yield is high, sticking material such as frozen soil and wet clay can be broken, and hard objects can be automatically removed. The breaker is especially suitable for breaking clay in cement and tile industry.

Description

Birotor cutting ring formula damp clay disintegrating machine

The utility model relates to a kind of disintegrating apparatus of building materials processing industry, is a kind of birotor cutting ring formula damp clay disintegrating machine.

The machine of breaking ground of China's use at present mainly contains two kinds of forms: a kind of is the vertical machine that breaks ground, it is to be hung on the vertical shaft that cutterhead is housed by a cylindrical tube, the blade that breaks ground, vertical shaft by bearing block be fixed in that cylindrical shell is upper and lower, in the ring flange, material is when falling, blade carries out the crosscut fragmentation.Another kind is a single rotor Grating disintegrating machine, and it is the broken structure of a kind of formula, is contained on the rotor of sickleshaped blade by bearing block according on the casing both sides, and the casing below is provided with the bar shaped grating, and material is discharged by screen(ing) machine by broken back in the turned cavities.

More than two kinds of confidential compression strength of asking of breaking ground less than 2-4 kilograms per centimeter 2, a because heap, factor affecting such as stope, contain finger stone in the material (clay), hard foreign material such as brick, during through crusher chamber, tend to break blade, squeeze bad (breaking) grating, or phenomenon such as stuck, moreover moisture content is less than 10%-15%, the South China Tropical rain forest climate, the clay water content is big, through preliminary treatment, water content also has about 30-35%, the northern China frost time is long, frozen soil not only firmly but also sticking, at this factor of natural environment, material can be bonded at increases motor load on the rotor, to burning out motor, material is bonded at discharging opening sometimes, and the obvious decline of output can not discharging.

The purpose of this utility model is to provide a kind of suitable fragmentation moist material, is particularly suitable for broken frozen soil, clay, and can get rid of the birotor cutting ring formula damp clay disintegrating machine of the hard thing in the material automatically.

Concrete scheme of the present utility model is: design seat formula casing, its top has charging aperture, discharging opening is established in the lower end, principal character is: two groups of broken rotors are housed in casing, it includes rotating shaft, knife rest, blade, supporting base, drive, two groups of broken rotor rotating speed differences, switched in opposite, and relative rotor is provided with the doctor blade holder of removing the clay between blade in casing, and around casing, install antiseized chain.

For improving crushing effect, the blade in the utility model is made disc.

The utility model feeding granularity is big, the output height, material from top to bottom drops in the middle of two groups of broken rotors, because two rotors are opposite to rolling motion, two groups of blades repeat to interlock, material by the time can very fast fragmentation, and the speed of two rotors is inconsistent, when running into hard material, the cutting ring sheet of rotor and rotor can also separate automatically, can not damage blade, can not block machine, and rotor is equipped with doctor blade holder relatively, run into the strong material of viscosity, scraper on the doctor blade holder can be removed automatically to epitrochanterian sticking thing, and the antiseized chain that is equipped with around the casing inner wall, can efficiently solve the difficult problem of the sticking machine of material, therefore the utility model also has long service life, keeps in repair few advantage.

The utility model will be further described below in conjunction with accompanying drawing:

Fig. 1 is the front view that partly cuts open of the present utility model;

Fig. 2 is the vertical view that partly cuts open of the present utility model.

Embodiment: referring to Fig. 1 Fig. 2, casing is made up of base 1 and loam cake 2, and discharging opening is offered in going to the bottom of base 1, the middle part of loam cake 2 is provided with charging aperture 4, also be provided with the access cover 3 of convenient maintenance on base 1 antetheca, the left and right sides is parallel in casing is equipped with two groups of broken rotors 5, and every group rotor is respectively by rotating shaft 8, knife rest 9, four groups of blades 10 (every group blade totally 10, be disc), two pairs of bearing blocks 11 and drive 12 are formed, two groups of its power configurations of broken rotor are the rotating speed difference, switched in opposite.For guaranteeing the not sticking machine of comminuting matter, doctor blade holder 6 is housed with the clay between automatic removing blade in the bottom of every group rotor, and around casing inner wall, is densely covered with antiseized chain 7, effectively solve the difficult problem of the sticking machine of material.

This machine is after use in the cement plant, and the type of the former same specification of PR has improved twice, and makes follow-up fluidized bed furnace consumption coal descend 20%, has good economic benefits and social benefit.

Claims

1. a kind of birotor cutting ring formula damp clay disintegrating machine that is used for building material industry, mainly form by casing, the broken rotor that is contained in the casing, charging aperture is established in the casing upper end, discharging opening is established in the lower end, rotor includes rotating shaft, knife rest, blade, supporting base, drive, it is characterized in that: design has two groups of broken rotors in the casing of this disintegrating machine, two groups of broken rotor rotating speed differences, switched in opposite, and in casing, set up the doctor blade holder of removing the clay between blade and in casing around densely covered antiseized chain is housed.

2. disintegrating machine according to claim 1 is characterized in that: the blade in the broken rotor group is a disk shape blade.
