Problems solved by technology

However, there are a series of problems in the existing calcination furnaces. The calcination of raw materials is not complete, and a large amount of heat loss is caused during calcination, which not only causes waste of fuel, but also partially wastes raw materials.

Abstract

The invention discloses a calcining furnace. The calcining furnace comprises a calcining furnace body, a before-calcining bin, a calcining pipeline and a temperature monitor; the outer wall of the calcining furnace body is covered with a heat insulation layer; the calcining pipeline is welded inside the calcining furnace body; a combustion machine is fixed at the top of the calcining furnace body;the temperature monitor is fixed in the middle of the inner wall of the calcining furnace body in a welding mode; a discharging hole is formed in the bottom of the calcining furnace body; the before-calcining bin is connected with a transition section through a quantitative feeding machine; a first adjusting screw rod is arranged at an outlet of the lower end of the before-calcining bin; and thetransition section is connected with a feeding pipeline through a conveying pipeline. The calcining pipeline provided by the invention is designed into an ''S'' shape, so that the time of raw materials in the calcining furnace body is prolonged, and thus the raw materials are calcined more thoroughly. The temperature monitor is arranged in the calcining furnace body, and when a proper temperatureis reached, the working of the combustion machine is stopped, so that the fuel consumption is reduced, and the waste of the raw materials is avoided.

Description

technical field [0001] The invention relates to a calciner, in particular to a high-temperature calciner. Background technique [0002] The high-temperature preheating process of solid carbonaceous raw materials in the absence of air or with little air is called calcination. During the calcination process, the structure and elemental composition of various carbonaceous raw materials undergo profound changes, resulting in enhanced physicochemical properties. The purpose of calcination is to remove the volatile components in the raw materials, increase the density and mechanical strength of the carbonaceous raw materials, improve the electrical conductivity of the raw materials, discharge the moisture in the raw materials and improve the chemical stability of the raw materials. However, there are a series of problems in the existing calcination furnaces. The calcination of raw materials is not complete, and a large amount of heat loss is caused during calcination, which not o...
