Hot air circulation heat storage type radiant tube heating sealing roller way kiln

Abstract

The invention discloses a hot air circulation heat storage type radiant tube heating sealing roller way kiln. The problems that in the prior art, temperature control is unstable, the heat efficiency is low, and the product percent of pass is low are solved. The kiln is characterized in that a kiln body comprises a preheating section (1), a constant-temperature section (2) and a cooling section (3); a roller transmission device, a circulation air device, a heating device and a cooling device are arranged in the kiln body, and a feeding kiln door (20) and a discharging kiln door (22) are formedin the two ends of the kiln body; a feeding chamber (4) and a discharging chamber (5) are additionally arranged at the two ends of the kiln body, a feeding chamber door (19) is formed in the feeding chamber (4), and a discharging chamber door (23) is formed in the discharging chamber (5); moisture eliminating systems are arranged on the preheating section and the constant-temperature section on the top of the kiln. The whole equipment is good in sealing performance and reasonable in structure and has the advantages that heating is uniform, the temperature is easy to control, and the quality ofproducts is high, the whole kiln is provided with a full-automatic feeding and discharging mechanism and a full-automatic detection and control system, the labor intensity of workers is reduced, theworking efficiency is improved, the firing percent of pass of the products reaches 99%, and energy is saved by 38%.

Description

Technical field: [0001] The invention belongs to the field of thermal equipment, in particular to a hot air circulation heat storage type radiant tube heating and sealing roller kiln. Background technique: [0002] In recent years, with the rapid development of industrial equipment technology at home and abroad, various professional kilns have emerged as the times require. Many products cannot be in contact with the flame during the heating process, such as the drying of some product bodies, or the heat treatment of products such as magnesia-calcium-carbon bricks and magnesia-calcium bricks. High-quality products require a good drying environment. Products such as magnesia-calcium-carbon bricks and magnesia-calcium bricks are widely used in steelmaking converters, electric furnaces, refining furnaces outside furnaces, ladles and other equipment. They are resistant to slag erosion, slag Permeability, thermal shock resistance and thermal conductivity and other properties. Ho...

Problems solved by technology

However, at present, manufacturers of such products generally use tunnel kilns, drying kilns and other furnace types to dry products or heat treat unfired bricks. Due to the poor sealing performance of tunnel kilns or drying kilns, unstable temperature control, and low overall thermal efficiency of the furnace, etc., The residual moisture content of the green body is too high, the green body cracks, resulting in defects such as low product qualification rate, high product energy consumption and production cost
