Fusion ceramic sand production equipment

Abstract

The invention discloses fusion ceramic sand production equipment. The fusion ceramic sand production equipment comprises a smelting furnace and a cooling bin. A sealing cover is arranged on the periphery of the smelting furnace. An opening is formed in the sealing cover and is in communication connection with an inlet of the cooling bin, accordingly, a closed cavity is formed by the cooling bin and the sealing cover, and the fusion ceramic sand is produced in the cavity. A closed system is composed of the sealing cover, a blowing way and the cooling bin, the high temperature generated by the smelting furnace is isolated from an operator through the sealing cover, safety of the operator is ensured, and environment friendliness is achieved; and cleanliness of ceramic fusion casting sand is guaranteed, the field operation environment is improved, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of ceramic sand production, and in particular relates to a production equipment of molten ceramic sand. Background technique [0002] Ceramic sand adopts unique technology, special production technology and pretreatment, and is made by high-temperature phasing method above 2000 ℃. Ceramic sand has very good impact strength and toughness, especially high hardness and surface smoothness, can be recycled and used repeatedly, has high utilization rate, wide particle size range, and strong optionality. [0003] In the prior art, the equipment used for ceramic melting and casting sand is mainly an open three-phase electrode furnace. The three-phase electrodes are placed in a T-shape in the furnace. After power-on, bauxite is added to the center of the electrode, and the bauxite is heated by arc ignition. Melting, the melt flows out from the nozzle of the furnace, and the melt is sprayed into particles by high-pre...

AI Technical Summary

Problems solved by technology

During production, the melting temperature of local materials can reach above 2000°C, and the siliceous flocs produced by a small part of high temperature are not easy to be sucked into the dust removal pipe, and fly in the air. During the melting process, the operator's observation of the furnace condition is unclear. The injection state of the molten liquid cannot be adjusted in time. The temperature of the entire production space is high and the environment is poor. The operation requires the operator to operate at close range throughout the process, which endangers the health of the operators.

In addition, due to the high operating temperature of the ceramic melting furnace, the dispersion of the siliceous flocs is high, and the collection is difficult. The collected ceramic melting casting sand is doped with impurities, and the production efficiency is low.
