The deficiency that the utility model exists for prior art and defect, provide a high purity magnesium hydrate air flow crushing device.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of high purity magnesium hydrate air flow crushing device, comprise pulverizing cylindrical shell, pulverizing cylindrical shell is fixed in the frame of airslide disintegrating mill, the external side of described pulverization cylinder is provided with gas distribution plate, described gas distribution plate is connected with compressed air source by tracheae, the spiral nozzle of the some that supply spray orifice is communicated with pulverization cylinder intracoelomic cavity after compressed air is distributed by described gas distribution plate, described spiral nozzle mounted in pairs is on pulverization cylinder body sidewall, this spiral nozzle is along the uniform setting of circumferencial direction of pulverizing cylindrical shell axis of rotation, and radially arrange to pulverize centered by cylindrical shell axis of rotation, described gas distribution plate is made up of outer and the internal layer be sleeved on inside outside, forms airtight filling interlayer, be provided with and have flexible filler in described filling interlayer between inside and outside layer.
In said structure, described filler adopts plastic foam or sponge.
In said structure, described filler is spring, and spring one end is fixed on outer inwall, and the other end is fixed on inner layer outer wall.
In said structure, during in order to prevent spiral nozzle air inlet, air-flow produces pressure oscillation, improve the stability entering spiral nozzle stream pressure, the air inlet pipe that described spiral nozzle is connected with gas distribution plate is provided with air-flow pressure stabilizing mechanism, described air-flow pressure stabilizing mechanism contains baroceptor and for regulating the servo valve of compression gas flow, the signal output part of described baroceptor is connected with the signal input part of signal processing control circuit, and the signal output part of signal processing control circuit is connected with the signal input part of servo valve.
The beneficial effects of the utility model are:
1. Compressed Gas is become irregular conical flow and sprays into and pulverize in cylindrical shell by spiral nozzle of the present utility model, the material pulverizing cylinder body bottom is blown afloat to be involved in supersonic airstream and pulverizes, and spiral nozzle mounted in pairs is on pulverization cylinder body sidewall, and radially arrange to pulverize centered by cylindrical shell axis of rotation, the air-flow sprayed into also form eddy current while forming supersonic airstream, further the material pulverizing cylinder body bottom is blown afloat to be involved in supersonic airstream and pulverize, dead angle phenomenon can not be produced, improve the crush efficiency of material.
2. be provided with between the medial and lateral of gas distribution plate of the present utility model and there is flexible filler, filler is used for cutting down the pressure oscillation produced when Compressed Gas enters gas distribution plate, avoid gas distribution plate because pressure oscillation produces vibrations, improve the pressure stability entering gas distribution plate air-flow, improve the quality of milling product.
