One-time palletizing-burning tunnel kiln

Abstract

The invention provides a one-time palletizing-burning tunnel kiln. Drying kiln air supply channels are respectively arranged on outer sides of inner kiln walls on the left side and the right side of a drying kiln, a plurality of air supply ports are arranged on the inner kiln walls in a dispersing mode and are communicated with an inner cavity of the drying kiln and the drying kiln air supply channels, and an moisture exhaust port for exhausting damp air is arranged at the top of the drying kiln. Calcining kiln air draft channels are respectively arranged on the outer sides of inner kiln walls on the left side and the right side of a calcining kiln, a plurality of air draft ports are arranged on the inner kiln walls in a dispersing mode and are communicated with an inner cavity of the calcining kiln and the calcining kiln air draft channels, the drying kiln air supply channels are communicated with the calcining kiln air draft channels through a fan, and hot smoke in the calcining kiln is exhausted and fed into the drying kiln for drying and preheating of adobes. The one-time palletizing-burning tunnel kiln has the advantages of being capable of efficiently producing brick and tile products in an energy-saving mode and greatly improving the work efficiency, being firm in structure, good in heat preserving performance and low in energy consumption, greatly improving labor working environment, effectively utilizing heat sucked from the calcining kiln to act on the drying kiln, enabling the heat to be utilized effectively and saving energy sources.

Description

technical field [0001] The invention belongs to thermal equipment suitable for continuous firing of bricks and tiles in the building materials, bricks and tiles industry, and relates to a tunnel kiln for one-time code firing. Background technique [0002] In the past, a wheel kiln was used to roast bricks and tiles. It was difficult to mechanize the kiln loading and unloading process, which required a large amount of labor. Workers operate in the dusty and high-temperature wheel kiln, and the working conditions are very poor. Existing tunnel kilns mostly use external metal air ducts, which are easily corroded by corrosive gases generated during the firing process, and the maintenance costs are high. Aiming at the current market situation, a new firing thermal equipment is needed. Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the present invention provides a tunnel kiln for one-shot firing with high efficiency, e...
