Self-ignition machined rod carbonization and carbonized kiln

Abstract

A self-burning machine-made rod carbonization is carried out by preparing raw material, mixed proportioning, drying, forming, loading, entering it into kiln, carbonizing, cooling, inspecting and packing. Kiln opening(3) and matched kiln gate(8) are arranged in front of special carbonizing kiln body, rail(2) is placed at kiln bottom, positioning ridge(7) is set in internal end of rail, smoke-discharging hole(5) in placed at internal wall of kiln wall(1), which is connected with chimney(6), kiln top is arched ceiling(4) and kiln wall(1) is sandwiched wall with thermal-insulating layer between double layers. It is efficient and cheap, has better quality and homogeneity. It can be used to fire machine-made carbon with refuse as raw material.

Description

technical field [0001] The invention relates to a production method of charcoal and a kiln for firing the charcoal, in particular to a carbonization method and a carbonization kiln in which machine-made rods are used as raw materials for spontaneous combustion and heating. Background technique [0002] Most of the forest areas in our country are located in mountainous areas, with inconvenient transportation and poor commodity circulation. Earth kilns with local materials and local methods are often used to make charcoal. A large amount of firewood forests are used as raw materials, and firewood weighing several times more than the weight is required. For fuel, the amount of forest loss is large, the charcoal produced is small, and the quality is uneven. The production cycle of charcoal in each kiln is as long as more than 20 days, and the efficiency is low. Earth kiln charcoal is still desirable because the kiln has low investment, simple operation technology, and is easy to...

[0004] CN1710021A discloses the patented technology of "spontaneous combustion carbonization kiln" of Kaibing artificial environmental protection carbon factory in Zhijiang City. It is a kiln body similar to a cube. The hole is connected, and the other end is connected to the chimney. When the charcoal is placed above the flue, the kiln roof is flat. The structure of the kiln lacks a reasonable amount of heat exchange channels. The internal combustion and heat storage are unfavorable, affecting the efficiency of spontaneous combustion, making it difficult to complete the refining process of carbonization, and the quality of charcoal is affected

The trolley for loading charcoal is not used, and it is extremely inconvenient to load the rods into the mechanism. To take out the charcoal, the kiln temperature needs to cool down to room temperature, which takes 2-3 days. When the charcoal is fired again, it needs to be refueled and preheated, which consumes energy and time.
