Coal blender

Abstract

The invention discloses a coal blending machine, which belongs to the technical field of coal material mixing, and comprises a car body and three batching hoppers, each of which is provided with a weighing mechanism and a material transporting mechanism, and the car body is also equipped with The material bin and the control device of the car body are connected with the discharge device and the scissor lifting device through the rotating device. The scissor lifting device is hinged with the discharge device. The weighing mechanism includes a weighing belt, a sealing unit and a first drive. mechanism, the material transport mechanism includes a closed casing, a material conveyor belt and a second drive mechanism, a blockage removal unit is also set inside the closed casing, and an anti-blocking device is fixed at the discharge port of the batching hopper and the discharge port of the sealing unit. The batching hopper is provided with a water outlet pipe for cleaning the inner wall of the batching hopper. The coal material of the present invention will not be blocked, and the phenomenon of diffuse coal dust can be avoided in the process of coal blending, which is beneficial to the protection of the environment and the health of workers, and is convenient for adjusting the tightness of the weighing belt. It has a long service life and is suitable for all Coal blender.

Description

technical field [0001] The invention belongs to the technical field of coal material mixing, in particular to a coal blender. Background technique [0002] Coal blending machine is one of the important equipment in coal mine production. Since the quality of coal used in different places is different, coal blending machine is needed to mix different types of coal and then sell them. The coal blending machine in the prior art mixes different coal materials and discharges them through the discharge device. Since the coal blending site is open, the final output materials are piled on the ground through the discharge device. Due to the amount of coal blending It is relatively large, and the accumulation of coal materials after discharge is also relatively high. In order to meet the accumulation of coal materials, the discharge device is set up at a certain angle, so that the output end of the discharge device is higher than the ground, and the final coal accumulation Larger, so ...

AI Technical Summary

Problems solved by technology

However, because the molecular structure of coal is not tight, when the coal in the silo falls into the weighing belt and the coal is transported by the mixing belt, it is easy to cause dust, which causes great damage to the workshop and other production sites. , not only pollute the environment, but also affect the health of the staff

Moreover, if the weighing belt carries high-density coal material for a long time, it will become loose, which will easily cause belt stripping and seriously affect the quality of the coal blender.
