An energy-saving and environment-friendly kiln

Abstract

The invention discloses an energy-saving and environmental-friendly kiln which comprises a kiln housing. A transmission shaft is arranged on one side of the kiln housing. A driving device is arrangedon one side of the transmission shaft. A PLC is arranged at the top of the transmission shaft. A first thermal insulating layer is arranged in the kiln housing. A first kiln group is arranged in the first thermal insulating layer, and comprises a first kiln and a second thermal insulating layer. A first material inlet is formed in one side of the first kiln. A first air outlet is formed in the other side of the first kiln. The driving device drives the transmission shaft and the kiln housing to rotate, the empty first kiln and the empty second kiln are transferred to the bottom of the whole kiln, a material at the bottom of the kiln is sequentially fed in the first kiln and the second kiln, climbing is not required, feeding and discharging are convenient and rapid, heat generated in heating is used for thermal insulation, gas in a first thermal insulating cavity is pumped in a second thermal insulating cavity through a return air outlet pipe, the second kiln is heated, waste heat is utilized, and energy consumption is reduced.

Description

technical field [0001] The invention relates to the field of kilns, in particular to an energy-saving and environment-friendly kiln. Background technique [0002] A kiln is a device made of refractory materials for firing products, and is an essential facility in pottery molding. It has developed from the open-air stacking and burning in the primitive society, digging pits and burning to steamed bun-shaped rising flame round kilns, half-down-flame horseshoe-shaped kilns, Banpo dragon kilns, and duck-egg-shaped kilns to today's indoor gas kilns and electric kilns. The kiln is a waste of cost for the production of less materials, the economic benefit is not high, and it cannot process materials with different heating temperatures at one time. In addition, there are many shortcomings that need to be improved. [0003] Therefore, it is necessary to invent an energy-saving and environment-friendly kiln to solve the above problems. Contents of the invention [0004] The object...
