Description
Technical field
The utility model belongs to a kind of reducing mechanism technical field, and in particular to a kind of air-flow crushing for preparing titanium dioxide
Device.
Background technology
Air flow crushing device be it is a kind of using compressed air by special nozzle to pulverizing chamber at a high speed spray, make material it
Between produce strong collision, friction and shearing so as to reaching the device of the purpose of crushing.Existing reducing mechanism efficiency low power consuming is big,
Also need installation auxiliary air-makeup system and cooling system, especially change that sieve is complicated, thus constrain reducing mechanism application and
Performance.
Utility model content
Technical problem to be solved in the utility model is to provide one kind for above-mentioned the deficiencies in the prior art to prepare titanium white
The air flow crushing device of powder, its efficiency high save again, and can save auxiliary air-makeup system and cooling system, and especially it changes sieve
It is convenient.
To realize above-mentioned technical purpose, the technical scheme that the utility model is taken is：
A kind of air flow crushing device for preparing titanium dioxide, wherein：Including motor, shaft coupling, broach hopper, upper box,
Main shaft, screen frame, grating disk, hammer leaf, lower box, frame, bearing and motor cabinet, described motor are fixedly mounted on motor cabinet,
Described main shaft is arranged on upper box by the output axis connection of shaft coupling and motor, described main shaft upper and lower ends by bearing
In lower box, described lower box is fixedly mounted in frame, and described upper box is arranged on nowel by screw and nut
On the top surface of body, described broach hopper is arranged on the top surface of upper box and broach hopper communicates with upper box, described sieve
Frame is fixedly mounted in upper box, and described grating disk is fixedly mounted on main shaft lower end, and described hammer leaf is arranged on grating disk.
To optimize above-mentioned technical proposal, the concrete measure taken also includes：
Above-mentioned upper box is flange plate structure form.
Above-mentioned screen frame adds the structure of bottom sieve using 360 ° of ring grizzlies.
Above-mentioned hammer leaf dimensions is 60mm × 20mm × 1.6mm and hammer leaf uses 65Mn alloy steel materials.
Material is added from charging aperture, and its movement locus is intersected vertically with rotating the movement locus of hammer leaf, thus material is hit
Rate is higher.It is rapid inside material particles under hammer leaf percussion because speed of the material with hammer leaf between the two differs greatly
The stress wave propagated to four directions is produced, and internally defect, crackle and crystal grain boundary etc. produce stress concentration, material will first
Along these fragile boundary breakings.On rotor upper strata, in the precomminution area that formed by shorter hammer leaf and sieve, most of material
Crushed or half crushes, crushed qualified thin material and run through the pulverizing chamber of ring grizzly hole discharge around.Half crushes and non-powder
Broken material continues to decline, and falls into the main crushed zone of lower floor.Because lower floor's hammer leaf end linear velocity is higher, with the gap of sieve more
Small, hammer leaf makes material obtain into one in addition to shearing force and impulsive force is continued to material, and with synergy such as abrasive powers
Step crushes, and by the air-flow normal pressure in pulverizing chamber, runs through ring grizzly and the discharge of bottom sieve sieve aperture, complete crushing and processing.
Crush tray bottom and scraping blade is housed, the material that can make to be deposited in bottom sieve is swept, and is got rid of with the centrifugal force of rotor to powder
Continue to crush in broken region.Scraping blade plays benefit wind action again, produces certain air quantity during rotation, the air pressure formed inside and outside pulverizing chamber
Difference, be advantageous to the discharge of fine powder, and the temperature difference inside and outside pulverizing chamber can be reduced, be advantageous to crushing and processing.Blast caused by scraping blade
The airflow state in pulverizing chamber can be improved, be advantageous to negative pressure inspiration material and malleation discharge, and destroyed in whole pulverizing chamber
Circulation layer, crushing qualified material is discharged in time, avoid repetition, invalid excessive crushing.
The utility model has the advantage of it is following some：Efficiency high saves again, and can save auxiliary air-makeup system and cooling
System, especially it, which is changed, sieves conveniently.
