Embodiment 1

[0039] In this embodiment, the inclination angle of the trough 1 is 25 degrees, and the rotation speed ratio of the stirring shaft 8 on the side far away from the discharge edge of the trough 1 and the stirring shaft 8 on the other side is 1:1.3, which is far away from the discharge edge of the trough 1. The stirring shaft 8 rotating speed on one side is 40 rpm.

Embodiment 2

[0041] In this embodiment, the inclination angle of the trough 1 is 35 degrees, and the rotation speed ratio of the stirring shaft 8 on the side far away from the discharge edge of the trough 1 and the stirring shaft 8 on the other side is 1:2.1, which is far away from the discharge edge of the trough 1. The stirring shaft 8 rotating speed on one side is 20 rev / mins.

Embodiment 3

[0043] In this embodiment, the inclination angle of the trough 1 is 30 degrees, and the rotation speed ratio of the stirring shaft 8 on the side far away from the discharge edge of the trough 1 and the stirring shaft 8 on the other side is 1:1.7, which is far away from the discharge edge of the trough 1. The stirring shaft 8 rotating speed on one side is 30 rev / mins.

[0044] The following table provides a comparison table of the production rate of the equipment and the drum granulator and the disc granulator for the above-mentioned embodiments.

[0045]

[0046] As can be seen from the above table, under the condition that the power of each equipment is consistent, the production rate of each embodiment of the present invention is obviously higher than the traditional drum granulator and disc granulator; Greatly reduce energy consumption.

Abstract

A particle forming device comprises a material tank used for filling solid materials, a stirring device used for stirring solid materials and a nozzle used for spraying liquid materials to the material tank. The stirring device is installed in the material tank. The nozzle is arranged above an opening of the material tank. The material tank has an angle facilitating internal solid material dumping, and the angle is 25-35 degrees. The particle forming device has unexpected technical effects due to the fact that the material tank is provided with the inclination angle. Inorganic silicon particles produced by the particle forming device is close to the ball shape and good in forming quality. The particle forming device is low in energy consumption and high in production efficiency.

Description

technical field [0001] The invention relates to granule forming equipment, in particular to a granule forming equipment especially suitable for the production of inorganic silicon solid particles. Background technique [0002] In industrial production, inorganic silicon is an important material. Inorganic silicon mainly includes silicon dioxide, sodium silicate, sodium metasilicate, sodium orthosilicate and other silicon-containing inorganic substances. Among them, silica is the raw material for manufacturing glass, quartz glass, water glass, optical fiber, important components of the electronic industry, optical instruments, handicrafts and refractory materials, and is an important material for scientific research; sodium silicate is widely used, almost Throughout all sectors of the national economy, it is used in the chemical industry to manufacture silica gel, white carbon black, zeolite molecular sieve, sodium metasilicate pentahydrate, silica sol, layer silicon and inst...
