Description

Moissanite sword material production high-temperature steam jet mill grinding system
Technical field
The utility model relates to raw mineral materials moissanites, more particularly, to a kind of moissanite sword material production high-temperature steam gas Flow crushing and classification system.
Background technique
Moissanite is a kind of more rare raw mineral materials.Natural moissanite be distributed widely in from magmatic rock to sedimentary rock, From aerolite to Shi Yan, from diamond to bauxite etc. in various rocks and mineral.Moissanite have superior toughness and Higher hardness (4000 or more Vickers hardness, slightly below diamond, but be higher than silicon carbide and boron carbide), is mainly used for making carbon Silica ceramic, electronic ceramics need to generally be made after sword material the crushing of raw material stone and carry out deep processing again.Currently, moissanite sword material is raw Production is all made of jet mill grinding system of the compressed air as gas source.The system is for hardness, the higher material powder of toughness value Broken efficiency is lower, time-consuming, and aerosol phenomenon, i.e. carbon especially can occur when being crushed to 0.87 micron of diameter of particle Silica surface generates electrostatic colloidal sol floor, cannot be further continued for being crushed, the depth of the production capacity and product that directly constrain enterprise is opened Hair.
Summary of the invention
The utility model, which provides a kind of with short production cycle, finished product materials granularity, can reach the carbon silicon that diameter is 0.6 micron Shi Ren expects production high-temperature steam jet mill grinding system.
To achieve the above object, the utility model can take following technical proposals:
The production of moissanite sword material high-temperature steam jet mill grinding system, including air-flow crushing described in the utility model Machine, symmetrically arranged two Lavalle ceramic nozzles pass through pipeline and high pressure steam boiler phase on the shell of the airslide disintegrating mill Connection, be placed in the shell of airslide disintegrating mill diameter be 1mm, accumulating amount 120kg/m3Silicon carbide medium ball, air-flow powder The top discharge pipe of broken machine is sequentially connected with cyclone separator, ceramic membrane type dust collector, the ceramics membrane type dust collection Air-introduced machine is provided in the evacuated tube of device.
The cyclone separator include the first cyclone separator and the second cyclone separator, first cyclone separator, Heat exchanger coil is provided in the inner walls of second cyclone separator and ceramic membrane type dust collector.
The emptying pipe end is provided with muffler.The cyclone separator includes the first cyclone separator and the second whirlwind Separator is all provided in the inner walls of first cyclone separator, the second cyclone separator and ceramic membrane type dust collector It is equipped with heat exchanger coil.
Moissanite sword material production high-temperature steam jet mill grinding system provided by the utility model, mainly passes through high temperature The collective effect of high-pressure steam and silicon carbide medium ball in airslide disintegrating mill accelerates the impact velocity of silicon carbide materials, rule Logistics vector deficiency has been kept away, the electrostatic colloidal sol floor that moissanite surface generates in crushing process has been effectively removed, by moissanite It is ground into the super fine that median particle diameter is 0.6 μm;Meanwhile passing through the gas-solids such as cyclone separator, ceramic membrane type dust collector Separation equipment makes system tail gas qualified discharge.The utility model (refers to the grain of comminuting matter to the good crushing effect of sic raw material Spend thinner), crush efficiency is high, is conducive to the deep processing production of moissanite, further develops the new function of the product.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Moissanite sword material production high-temperature steam air-flow powder described in the utility model is illustrated with specific embodiment below Broken hierarchy system.
As shown in Figure 1, the utility model includes the boiler 1 for producing 150 DEG C, 0.7-0.8MPa water vapour, boiler 1 steams Steam pipe is connected with two Lavalle ceramic nozzles symmetrical on 2 shell of airslide disintegrating mill, in the shell of airslide disintegrating mill 2 It is placed with the silicon carbide medium ball 3 that diameter is 1mm, the accumulating amount of silicon carbide medium ball 3 is mark according to the volume of airslide disintegrating mill 2 Standard, usual every cube of placement 120kg needs regular replenishment when attrition occurs in silicon carbide medium ball 3, to keep 120kg/ m3Accumulating amount.The top discharge pipe of airslide disintegrating mill 2 and the first cyclone separator 3.1, the second cyclone separator 3.2 and ceramics Membrane type dust collector 4 is sequentially connected, and is equipped with air-introduced machine 5 in the evacuated tube of ceramic membrane type dust collector 4, is being emptied Pipe end is equipped with muffler 6.
When work, the moissanite raw material micro mist that median particle is 57 μm is uniformly sent into airslide disintegrating mill by ingredient conveyor In 2 shells, meanwhile, 150 DEG C in steam pipe, the water vapour of 0.7-0.8 megapascal through Lavalle ceramic nozzle acceleration after will form Supersonic airstream makes the intracorporal silicon carbide medium ball 3 of chamber and moissanite granules accelerate collision, effectively overcomes material molecule Between Van der Waals force, eliminate material agglomeration and electrostatic effect, most of moissanite made quickly to be ground to median particle diameter 0.6 μm of superfine powder;Meanwhile steam stream can also remove the impurity in superfine powder, ease off the pressure for subsequent dedusting.Crushed material Material rises with high pressure steam flow, and superfine powder up to standard passes through high-speed rotating grading wheel impeller clearance in airslide disintegrating mill 2 and reaches out Material mouth;And biggish non-conforming particle, due to the centrifugal force effect of classification impeller blade, is thrown to blade outer rim in uphill process And cavity bottom is dropped down onto, it is crushed again in airslide disintegrating mill 2.By adjusting the available different grains of revolving speed of grading wheel The product of diameter.From 2 discharge port of airslide disintegrating mill be discharged silicon carbide ultrafine powder up to standard sequentially enter the first cyclone separator 3.1, Gas solid separation is carried out in second cyclone separator 3.2, silicon carbide ultrafine powder is collected by the rewinding tank of deduster bottom, dust-laden Gas then goes successively to ceramic membrane type dust collector 4 and is dusted operation, most afterwards through evacuated tube qualified discharge.
In the shell of above-mentioned first cyclone separator 3.1, the second cyclone separator 3.2 and ceramic membrane type dust collector 4 It is separately installed with heat exchanger coil a, b, c on wall, is passed through soft water in coil pipe, heat exchange, gas temperature occurs with high-temperature dusty gas Degree reduces, and soft water temperature increases, and high temperature soft water is returned to for producing the high temperature and high pressure steam of airslide disintegrating mill 3 in boiler 1, It can achieve energy saving purpose.
The utility model is controlled using full-automatic computer, prevents human factor, entire production process is controlled by computer Cabinet, which automatically controls, to carry out, and computer control cabinet supplies entire production process, automatic start-stop, automatic protection, fault alarm and automatic It shuts down, ensures the stabilization of equipment safety operation and product quality.
