Silica sand scrubbing unit

Abstract

The invention discloses a silica sand scrubbing unit. The silica sand scrubbing unit comprises a tank body, a filter cylinder is arranged in an inner cavity of the tank body, the top end and the bottom end of the filter cylinder are correspondingly and fixedly connected with the top and the bottom of the inner cavity of the tank body, stirring blades are vertically arranged in the filter cylinder, the axes of the stirring blades deviate from the axis of the tank body, and a rotating shaft is fixedly connected to the axes of the stirring blades. A motor is mounted at the top of the tank body, the rotating shaft penetrates through the tank wall of the tank body and is fixedly connected with a rotor of the motor, a bearing sleeves the position, penetrating through the tank wall of the tank body, of the rotating shaft, a feeding hole is formed in the top of the tank body, a discharging pipe is connected to the bottom of the tank body, the tank body is connected with a water inlet pipe, the feeding hole, the discharge pipe and the tank body are connected, the water inlet pipe and the tank body are connected on the inner side of the filter cartridge, and a water outlet pipe is connected on the side wall of the tank body. In the silica sand scrubbing unit, the stirring blades are driven to rotate, so that liquid drives a silica sand material to be scrubbed to impact the filter cylinder, and an impurity film wrapping the surface of the silica sand material can be destroyed.

Description

technical field [0001] The invention relates to the technical field of silica sand pretreatment, in particular to a silica sand scrubbing unit. Background technique [0002] Silica sand, also known as silicon dioxide or quartz sand, is a refractory particle with quartz as the main mineral component and a particle size of 0.02-3.35mm. Silica sand is a hard, wear-resistant, chemically stable silicate mineral, and its main mineral component is SiO2. Silica sand is an important industrial mineral raw material, which can be widely used in glass, casting, ceramics and refractory materials, metallurgy, construction, chemical industry, plastics, rubber, abrasives and other industries. [0003] Nowadays, the demand for silica sand is increasing, and natural granular silica sand has become the best choice because of its relatively high silica content and small particles. [0004] However, due to the wind and sun on the surface of the silica sand, the dust and other useless impuritie...

AI Technical Summary

Problems solved by technology

[0004] However, due to the wind and sun on the surface of silica sand, the dust and other useless impurities attached to the surface of the particles are difficult to melt and remove during firing, thus bringing adverse effects on subsequent processed products

[0005] In the prior art, the silica sand is usually pretreated by scrubbing. At present, the scrubbing machines used in my country have low scrubbing strength and short residence time of materials in the scrubbing machine, resulting in low scrubbing efficiency and unsatisfactory scrubbing effect.
