Abstract

The invention discloses a preparation method of high-utilization-rate machine-made charcoal. The preparation method comprises the following steps: crushing raw materials by a crusher and uniformly stirring with phenolic resin to obtain a blank; molding the blank into a blank with the density of 1-1.3g/cm < 3 > by a blank hot press under the conditions that the pressure intensity is 10-20MPa and the temperature is 150-200 DEG C and sawing the blank into a required specification after discharging; carrying out semi-finished product molding processing by a rod molding machine and carrying out rodmolding; heating in the machine at 350-420 DEG C to obtain a semi-finished product for later use; stacking and airing the obtained semi-finished product for later use; and filling the aired semi-finished product into a carbonization furnace, carbonizing at 500-600 DEG C under the condition of introducing air and naturally cooling to obtain the machine-made charcoal. According to the preparation method of the high-utilization-rate machine-made charcoal, disclosed by the invention, the utilization rate of fuel wood, shrubs, branches, barks, wood processing residues or waste artificial boards can be improved to be more than 60%.

Description

technical field [0001] The invention relates to the technical field of machine-made charcoal, in particular to a preparation method of machine-made charcoal with high utilization rate. Background technique [0002] Mechanism charcoal is also known as mechanism charcoal, salary stick, artificial charcoal, regenerated charcoal, smokeless clean charcoal, and stick charcoal has a wide range of raw materials, such as rice husk, peanut shell, cotton husk, corn cob, corn stalk, sorghum stalk, etc. The raw materials for producing stick charcoal are best sawdust, shavings, and bamboo chips. Because the mechanism charcoal is smokeless, odorless and non-toxic, it has been widely used for home heating and barbecue food; in the industrial field, it can be used as industrial raw materials and further processed into activated carbon, etc. Due to its high density, high calorific value, smokeless, odorless, pollution-free, non-explosive and flammable charcoal, it is an internationally recog...
