The specific embodiment

The present invention is described in further detail below in conjunction with the drawings and specific embodiments.

As shown in Figure 1: multistage turbine pulverizer embodiment of the present invention, being superposeed up and down by four turbine disintegrating machines 1 connects to form, and turbine disintegrating machine rotary speed increases progressively from top to bottom successively.

Referring to Fig. 2 to Fig. 6, every turbine disintegrating machine 1 from top to bottom comprises again: opening two ends up has the last feeding cylinder body 2 of adpting flange, is provided with taper feed hopper 3 in the tube, and tube end perforate is corresponding to hopper outlet; One opening two ends up has the broken cylindrical shell 4 that adpting flange, upper flanges are connected with flange at the bottom of the last feeding cylinder body tube, be provided with the diaphragm plate of separating up and down 9 in the middle of the broken cylindrical shell 4, cylindrical shell top constitutes crusher chamber 10, inwall is provided with wearing layer 5, and it is: to encircle the wear-resisting pipe box that is fixed on the crusher chamber inwall up and down; Diaphragm plate has interstitial hole and side opening 91; Be provided with motor 8 in the cylindrical shell bottom, its vertical output shaft is equipped with the turbine disk 6 after passing the dividing plate interstitial hole, motor reel is connected by key with the turbine disk, the turbine disk 6 correspondences are in taper feed hopper 3 outlet belows, the structure of this routine turbine disk 6 is a hollow disc, have material receiving port 61 in the middle of the end face, have shaft with keyway hole 62 in the middle of the bottom surface and cooperate with the vertical output shaft of motor, the side has four and gets rid of material mouth 63.

Have discharge opening 41 corresponding to diaphragm plate side opening 91 at the bottom of 4 of the broken cylindrical shells; In the middle of the cylindrical shell bottom is divided into two longitudinal baffles 12 and both sides, both sides are up and down respectively corresponding to a described diaphragm plate side opening 91 and a tube end discharge opening 41, motor is installed in the centre of cylindrical shell bottom, and the motor both sides are tapping channel, and the cylindrical shell wallboard perforate 42 of pars intermedia both sides makes things convenient for disassembling and assembling machine.

Fig. 7 and shown in Figure 8 be the structure of the another kind of turbine disk:

The garden plate of one impeller and its below is fixed together or one is made, and has the shaft with keyway hole in the middle of the plate bottom surface, garden and cooperates with the vertical output shaft of motor.

Certainly, the structure of the turbine disk can also have other form, as long as the material that can will fall is thereon thrown the crusher chamber wall away.

Every turbine disintegrating machine is fixed with bolt, spring washer, nut by adpting flange, the superiors are that the charging cylindrical shell of first turbine disintegrating machine is as charging aperture, from top to bottom the discharging cylindrical shell of the turbine disintegrating machine on each layer all is communicated with the charging cylindrical shell of turbine disintegrating machine on the adjacent layer, and the bottom discharging cylindrical shell of the 4th turbine disintegrating machine is as discharging opening.

The turbine disk of each turbine disintegrating machine can turn clockwise, and also can be rotated counterclockwise, and also can rotate in opposite directions; From top to bottom the secondary speed of each disintegrating machine raises step by step.

In addition, the motor of described turbine disintegrating machine also can change the hydraulic motor drive into.

The course of work: material particles enters in the turbine disk of first disintegrating machine in the taper feed hopper of last feeding cylinder body, by motor and key, motor turns clockwise, driving the turbine disk and material rotates in the crusher chamber indoor high-speed, material throws away and forms continuous material curtain, material is subjected to the effect of turbine disk centrifugal force and acceleration of gravity, in crusher chamber, impact voluntarily mutually, rub, and follow-up material continuously throws away to wearing layer, material crusher chamber indoor as bullet beat that the hail of bullets are impacted, hit being subjected to, collision friction and pulverizing.

Material through the 1st turbine disk crusher in crushing, continuously enter into the taper charging aperture of the 2nd turbine disk disintegrating machine top charging cylindrical shell, enter the turbine disk of the 2nd turbine disk disintegrating machine, the turbine disk up time rotation of the 2nd turbine disk disintegrating machine, material is thrown on the wearing layer material on every side by the turbine disk once more, and material is subjected to impact, strike, collision once more, rubbing makes the material pulverizing.Through the comminuting matter of second turbine disk disintegrating machine, repeat the aforesaid operations process, material particles enters the 3rd～4 crusher in crushing chamber in mode continuously, carries out crushing and grinding, finally makes material meet the requirements of superfine powder.

In the above-mentioned multistage turbine dish flour mill, material enters in the turbine disk of first turbine disk disintegrating machine, because the turbine disk rotates, the rotation of drive material produces air force, material particles flows in the indoor rotation of crusher chamber, and material particles and material produce impact, extruding, collision once more, rubbing grinds material.Again because many turbine disk disintegrating machine series connection, it is the broken chamber series connection of many turbine disk disintegrating machines, every crusher turbine dish is also connected, a kind of multistage turbine dish flour mill of the present invention and powder concentrator can be formed closed cycle, the above superfine powder of 325 orders is selected through powder concentrator, and the following material particles of 325 orders returns in the grinding machine to be regrinded.

The turbine disk rotating speed of every disintegrating machine is high more, and the material particles grinding is just tiny more, otherwise just big; Disintegrating machine series connection platform number is many more, material particles grinding tiny more, and the order number is high more.
