An energy-saving kiln with circular moving plates

Abstract

Disclosed is an annular moving plate energy conservation kiln. The annular moving plate energy conservation kiln solves the problems that an existing tunnel kiln is large in heat waste and large in temperature difference, and overcomes the defects that a roller kiln and a push slab kiln frequently break down and the like. The annular moving plate energy conservation kiln is assembled by combining a center vertical shaft, an annular kiln body frame, an annular kiln cavity, an annular seal kiln bottom, transmission and combustion systems related to the annular moving plate energy conservation kiln and the like. The annular seal kiln bottom is composed of two annular planes formed by arranging two groups of annular beams in stagger mode and used to support different portions of a refractory slab, wherein one group of the annular beams intermittently falls and rises from a normal position, the other group of the annular beams intermittently moves forward and backward, and the annular beams support regular intermittent movement of the refractory slab through the above orderly and alternate movement. The refractory slab bears a roasted object during a firing period completed by enabling the roasted object to enter an annular tunnel from an entrance and detour to a material entrance and exit through a preheating zone, a firing zone and a cooling zone. The annular moving plate energy conservation kiln has the advantages of being creative in structure, small in temperature difference, high in quality, easy to operate, few in breakdown and convenient to maintain, reducing energy consumption, saving labor and time and the like, and furthermore is widely suitable for roasting and decoration firing of all ceramic products.

Description

technical field [0001] The invention relates to the technical field of energy-saving kilns, and relates to an energy-saving kiln with circular moving plates. Background technique [0002] Tunnel kiln is a widely used kiln. Existing tunnel kilns have large heat loss and large temperature difference. However, roller kilns and pusher kilns have frequent failures and short overhaul periods. [0003] Invention content: [0004] The object of the present invention is to provide an energy-saving kiln with circular plate shifting, which has the characteristics of high efficiency, low failure rate and long overhaul period. It consists of a central vertical shaft, an adjustable turntable, an annular kiln body frame, an annular kiln cavity, an annular sealed kiln bottom, and a transmission system related to the kiln, a plate moving device, a combustion system, a temperature control system, and a waste heat utilization system. made. Because half of the kiln wall inside the kiln cavi...
