The invention relates to devices

to disperse the crystals of thermally expanded mica and can be used in the production of micluenite

paper, slyudinita, etc.

The aim of the invention is the expansion of the technological capabilities of the pulper.

FIG. 1 shows the pulper, general view, section; in FIG. 2, the same plan view.

Thermally expanded mica pulper contains case T, the bottom of which is made in the form of a screw conveyor 2. Vertical partitions 3 and 4 case 1 is divided into loading 5, classification 6, soothing 7 and upper 8 cameras, and the partition 4 separating the classification and soothing chambers is installed on the trolley 9, which with the help of a screw drive 10, has the ability to move along the body

1. The disperser 11, which is a centrifugal pump, is installed next to the housing 1. Its suction nozzle is connected by a pipe 12 to the lower part of the loading chamber, and the pressure nozzle by a pipe 13 is connected to the upper 8 camera.

The collection of waste of un-splitted mica is carried out in the tank 14, the pulp of a given concentration is discharged through the discharge pipe 15, displaced by the circulating water supplied through the pipe 16.

The pulper works as follows.

Through the pipe 16, the pulper along with the dispersant 11 is filled with circulating water. Thermally and swollen mica crystals from the metal basin (not shown) are fed into the loading chamber 5. The fluid flow created by the dispersant 11, mica is drawn into the circulation and through pipelines 12 and 13 is fed into the top 8 chamber, intensively splitting into the dispersant 11. Subsequently, the pulp passes through the soothing 7, classification 6 and returns to the loading 5 chamber.

In the soothing chamber, the flow of the pulp stabilizes, particles of mica float in it, which, due to a significant amount of trapped air, turned out to be lighter than water. These particles, as the air is replaced by water, sink and, together with the pulp, enter the classification chamber 6, where, under the conditions of the upward flow generated by the circulating water supplied through the nozzle 16,

mica particles of a given particle size are separated and removed in the form of pulp through the discharge pipe 15. Large mica particles enter the loading chamber 5 and then re-splitting into the dispersant 11. The particle size distribution of the pulp is controlled by changing the upward flow rate in the classification chamber 6 by displacement of the partition 4 separating the classification 6 and the soothing camera 7, using a screw drive 10.

Unsplitted crystals of mica and rock are deposited on the bottom and removed by screw conveyor 2 from the pulper.

The design of the thermally expanded mica pulper by eliminating the ingress of large crystals of mica into the pulp used in paper production, improving its particle size distribution, reducing the amount of mica that is removed along with the unsplit crystals improves the quality of the mica materials obtained and reduces the mica consumption per unit. finished products by 10%.

Claims (3)

Claim 1. The pulper thermally expanded mica containing loading and unloading nozzles, housing and disperser, characterized by that, in order to expand technological capabilities, the body is made in the form of a straight prism, in which the bases are arranged vertically, and the side face downward is inclined to the horizontal plane and formed by the screw conveyor body, the body space above the conveyor is divided by vertical partitions into successive loading, classification , sedative and upper chambers, while the partition separating the classification and soothing chambers is installed with the possibility eremescheniya along the longitudinal axis of the housing, wherein the suction nozzle dispersant connected to the lower part loading chamber, the discharge pipe - with the upper chamber, and ragruzochny nozzle disposed in the upper part of the classification chamber. 2. The pulper according to claim 1, of which is inclined in that the dispersant is designed as a centrifugal pump. 3. Pulper pop. (characterized in that the angle of inclination of the side face of the prism to the horizontal plane is 15-45 °. 1680325
