Rod marking machine for charcoal processing

Abstract

The invention relates to the technical field of wood processing, and discloses a rod making machine for charcoal processing. The rod making machine for charcoal processing comprises a machine body, adriving device, a spiral propeller, a feeder, a feeding hopper and a heating ring; the driving device is mounted at the top of the machine body; the spiral propeller is fixedly connected to a shaft part of the driving device; the feeder is placed outside the spiral propeller; the feeding hopper is mounted on the spiral propeller; the heating ring is mounted at a discharging pipe of the spiral propeller; and a sleeving is mounted on the spiral propeller. The temperature in the feeder can be sensed in real time by an expanding liquid by means of a principle of expanding by heat and retracting bycold of the expanding liquid; when the temperature in the feeder exceeds a normal value, the expanding liquid is expanded by heat to drive a sliding block to slide to one side, so that a pressing plate is bent downward gradually; therefore, water flow in water absorbing sponge is extruded out to reduce the temperature of the feeder; raw materials are positioned in an appropriate environment in aprocessing process; and proper humidity and viscosity of the raw materials are maintained in the processing process.

Description

technical field [0001] The invention relates to the technical field of charcoal processing, in particular to a rod making machine for charcoal processing. Background technique [0002] The rod making machine is the main equipment for making rod-shaped solid fuel by using wood, rice husk, peanut shell, plant straw and other carbon-containing woody materials (without any additives) under high pressure and high temperature conditions. [0003] The working principle of the existing rod making machine is as follows: Figure 4 As shown, the material enters the interior of the feeder through the feeding hopper, and then the driving device rotates to drive the screw propeller to rotate. Under the action of the screw propeller and the heating ring, a high-temperature and high-pressure zone is formed to process the loose raw material into a hollow rod. During the storage or collection process, there will be a certain amount of water content. When the raw material is heated and melted,...

[0003] The working principle of the existing rod making machine is as follows: Figure 4 As shown, the material enters the interior of the feeder through the feeding hopper, and then the driving device rotates to drive the screw propeller to rotate. Under the action of the screw propeller and the heating ring, a high-temperature and high-pressure zone is formed to process the loose raw material into a hollow rod. During the storage or collection process, there will be a certain amount of water content. When the raw material is heated and melted, the internal moisture will be evaporated by the hot air to form water vapor. In addition, the feeder is sealed, so that water vapor cannot flow from the bar. The central hole is discharged. As the temperature rises, the water vapor accumulates more and more, causing the internal water content of the discharge pipe to increase, causing the bar to absorb a large amount of moisture during the discharge process. The existence of moisture causes the bar to overheat. The soft surface liquefies and adheres to the inner wall of the discharge pipe during the extrusion process, resulting in an increase in the wall resistance and a smaller aperture of the discharge pipe, which affects the normal discharge of the rod, and the existence of water vapor will impact The inner wall of the bar causes the surface of the bar to crack and cannot form a complete bar. At the same time, the existence of a large amount of water vapor will occupy the space of the discharge pipe, resulting in an increasingly high temperature of the discharge pipe, which gradually exceeds the adaptability of the raw material. The temperature will also cause the raw materials to be too dry, which will cause the materials to be unable to soften and bond together, and the materials will crack and break when they are discharged, which will further affect the quality of the rods.
