Sleeve type silica sand drying device

Abstract

The invention discloses a sleeve type silica sand drying device. The sleeve type silica sand drying device comprises a support, an outer cylinder, a rotating cylinder and an inner cylinder. The rotating cylinder is rotationally arranged on the support and connected with a drive mechanism, the rotating axis of the rotating cylinder is parallel to the center axis of the rotating cylinder and is eccentrically arranged from the center axis, and the outer cylinder is arranged on the periphery of the rotating cylinder in a sleeving manner and is in sealed connection with the rotating cylinder. According to the sleeve type silica sand drying device, by means of the eccentric rotation of the rotating cylinder, silica sand in the rotating cylinder can rotate along with the rotating cylinder, the silica sand is sufficiently stirred in the rotating cylinder, and agglomeration is avoided. Hot air is exhausted into the rotating cylinder through first exhaust holes in the inner cylinder, the directions that the hot air is emitted into the rotating cylinder are increased, the pressure that the hot air is emitted into the rotating cylinder is also increased, and therefore by increasing the intense degree of convection between the silica sand and the hot air, the hot air and the silica sand are mixed more sufficiently, and the drying and dedusting effects of the hot air on the silica sand are improved.

Description

technical field [0001] The invention relates to the technical field of silica sand drying, in particular to a sleeve type silica sand drying device. Background technique [0002] High-purity quartz sand is the only raw material for producing high-quality quartz glass used in high-tech fields such as optical fiber communication, electronics industry, semiconductor, solar energy, laser and aerospace, and its market demand is large. Quartz stone is the only raw material for producing high-purity quartz sand. [0003] Quartz stone is a non-metallic mineral, a hard, wear-resistant, chemically stable silicate mineral, and its main mineral component is SiO 2 , Therefore, quartz stone is also known as silica. Quartz sand is a kind of quartz particles obtained by crushing and processing quartz stone. It is produced from natural quartz ore as raw material. The production process of quartz sand mainly includes crushing, impurity removal, and cleaning. In order to facilitate preserva...

Problems solved by technology

In order to facilitate preservation and packaging, the quartz sand must be dehumidified after being washed with water. The existing quartz sand dehumidification device is either large in structure, not suitable for small industrial use, or complex in operation and high in cost.
