Multi-head rod making method and used energy-saving environmental protection rod making device

Abstract

The invention discloses a multi-head rod making method and an energy saving and environmental protection rod making machine used by the method. The method uses a multi-output shaft reducer, each output shaft of the reducer drives a set of rod pressing device which is located in a charging bucket, a feeder and a spiral presser in the rod pressing device together press the raw material sawdust in the charging bucket to form a sawdust rod from the hole of a long internal sleeve through an exhausting sleeve and a compressing sleeve. The sawdust in the long internal sleeve is simultaneously heated during the course of pressing. The invention can realize an intensive production of machine-made charcoal, the occupied area of the workshop is reduced, the energy consumption is reduced, and the flue gas is recycled beneficially. The pollution of the working environment in the production zone is reduced, the working environment is improved, and the production is increased. The charcoal made out is loose outside but tight inside, the production quality of the charcoal can be improved, the burning of the charcoal in the course of combustion is fast, the combustion time after burned is as long as 4 to 5 hours, the residual ash on the surface is easily shed, the heat value reaches about 8000 kcal, and the equipment is easy to be maintained, so the maintenance cost of the equipment is reduced.

Description

technical field [0001] The invention relates to a rod making method and a rod making machine, in particular to a multi-head rod making method and an energy-saving and environment-friendly rod making machine. Background technique [0002] The production of mechanism charcoal uses a rod making machine. The existing rod making machines are generally single-headed, and the efficiency is low. Although the efficiency can be improved if multiple single-headed rod-making machines are used, multiple single-headed rod-making machines need to occupy a large amount of space. of plant area. The power of the existing single-head rod-making machine is about 22KW. If multiple single-head rod-making machines are used to work at the same time, the power consumption will increase exponentially. In addition, during the charcoal making process, the flue gas generated can be recycled, and the scattered placement of multiple single-head rod making machines is not conducive to the recovery of flue...

AI Technical Summary

Problems solved by technology

The density of the carbon rod extruded by the pressing device of the existing single-head rod making machine is tight on the outside and loose on the inside. The user uses this carbon rod to ignite slowly during the combustion process, and the burning time is short after the fire. The residual ash on the surface is not easy to fall off, which affects the temperature. lower calorific value

In terms of structure, the screw presser of the existing single-head rod making machine is installed in the long inner sleeve. After a period of use, the screw presser and the long inner sleeve will be worn and cannot be repaired. After one or two months, it will be scrapped and replaced with new inner sleeve parts, resulting in waste of materials and high production costs

Due to the structural problems of the screw press, the existing single-head rod making machine has a small amount of material per unit time, and the pressed density of the carbon rod is low.
