Manufacturing method of solid charcoal in compression molding mode

Abstract

The invention discloses a manufacturing method of solid charcoal in a compression molding mode. Raw materials comprise fuel wood, shrubs, branches, bark, wood processing residuums or discarded artificial boards, the raw materials do not need to be smashed and can be directly formed through a pressing machine in a mold pressing mode, the pressed materials and a mold are heated for carbonization in a carbonizing furnace, the pressed materials are carbonized in the mold, and finished solid charcoal is obtained in a compression molding mode after cooling demolding. Integrated processes of mold pressing cold state forming through the pressing machine and carbonization in the mold is adopted, so that excellent combination of a carbonizing process hot condition and an anaerobic condition is achieved, and all the raw materials with low use value, such as the fuel wood, the shrubs, the branches, the bark, the wood processing residuums or the discarded artificial boards, are enabled to be fully utilized. Products are put in order, the content of fixed carbon is high, charcoal obtaining rate is high, the production time is short, the yield is high, large scale production can be achieved, and a new way is provided for development and utilization of continuous biomass energy.

Description

【Technical Field】 [0001] The invention relates to the technical field of charcoal manufacturing. 【Background technique】 [0002] In the prior art, the burning of charcoal is mainly the method of machine-made charcoal. The traditional earth kiln to burn wood or fuelwood has been basically replaced by machine-made charcoal due to resource problems and national policies. [0003] Machine-made charcoal firing methods generally use wood sawdust as the main raw material, branches, rice husks, bamboo shavings, peanut skins, sunflower husks, furfural residue, wine residue, bagasse, corn cobs, coconut husks, coffee husks and north and south Square crop straws can also be used after being crushed, but the machine-made rod screw extruder has strict requirements on the moisture content and fineness of the raw materials. It often needs to be crushed several times. The energy consumption and labor increase the manufacturing cost, which is very difficult in actual production. Less application; t...

Problems solved by technology

[0004] The machine-made charcoal firing method utilizes the wood sawdust left over from wood processing, which is difficult to use for large wood processing residues such as cut ends, saw edges, planers, etc. Yes, this is a big deficiency
