High-temperature solid conveyor device

Abstract

The invention relates to a high-temperature solid conveyor device mainly comprising an insulation tank body, anti-broken chute and a classification pore plate, wherein the top of the insulation tank body is provided with a high-temperature solid inlet, and the lateral part of the insulation tank body is provided with a high-temperature solid outlet ; the anti-broken chute is vertically arranged atthe upper part of an inner cavity of the insulation tank body, and the upper end of the anti-broken chute is located below the high-temperature solid inlet; the classification pore plate is arrangedbelow the anti-broken chute, and obliquely installed in the inner cavity of the insulation tank body; high-temperature solids are slid onto the classification pore plate through the anti-broken chute,and quickly discharged from the high-temperature solid outlet after passing through the classification pore plate. According to the conveyor device, the classification and removal treatment of powderis achieved in the material conveying process after pulverization, and the power is prevented from entering a calcium carbide furnace; meanwhile, the conveyor device has a thermal insulation function, and the sensible heat loss of the high-temperature solids is reduced; and the energy consumption in the calcium carbide production process and the carbon emission are reduced.

Description

technical field [0001] The invention belongs to the field of conveying technology, and relates to a high-temperature solid conveying device, in particular to heat preservation and conveying of calcium carbide raw materials. Background technique [0002] As an important chemical raw material, calcium carbide is mainly used in the production of acetylene and acetylene-based chemical products. It was once known as the "mother of the organic synthesis industry". From the perspective of energy distribution in my country, "rich in coal, poor in oil, and low in gas" is a typical feature of my country's energy structure. Coal is the main energy source in my country, accounting for about 70% of primary energy. Therefore, calcium carbide production is of great significance to the development of industrial economy. . The traditional calcium carbide production mainly adopts the electrothermal method, that is, lump quicklime and lump coke are used as raw materials, which are heated by el...
