Coal gangue drying device

Abstract

The invention discloses a coal gangue drying device, and particularly relates to the field of coal gangue drying. The coal gangue drying device comprises a box body, a draught fan is arranged at one side of the box body, an air exhaust pipe is arranged at one side of the draught fan, the draught fan is fixedly connected with the air exhaust pipe, and the other side of the draught fan is provided with a first air outlet pipe; one end of the first air outlet pipe is fixedly connected with the draught fan, the other end of the first air outlet pipe is fixedly connected with the box body, the topof the first air outlet pipe is provided with a second air outlet pipe, and the second air outlet pipe is arranged at the outer side of the box body and fixedly connected with the first air outlet pipe; an air discharge port is formed in the other side of the box body, and a filter net is arranged at the bottom of the air discharge port, arranged inside the box body, and fixedly connected with thebox body. According to the coal gangue drying device, by introducing air into the box body through the draught an, dust on the surface of coal gangue fallen into the box body is blown off, the dust which is blown off falls onto an accumulated water layer, dust is prevented from rising again, the working procedures are simple, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of coal gangue drying, and more specifically, the invention relates to a coal gangue drying device. Background technique [0002] Coal gangue is a rock mixed with organic and inorganic compounds co-deposited with coal during the coal-forming process, usually in the form of a thin layer and in the coal seam or at the top or bottom of the coal seam. It is used in coal mine construction and coal mining, washing and processing A large amount of mine solid waste generated during the process. Coal gangue can be divided into clay rock, sandstone rock, carbonate and aluminum rock according to the main mineral content. According to the source and final state, coal gangue can be divided into In order to excavate gangue, selected coal gangue and natural gangue, coal gangue replaces clay as a raw material for brick making, which can save fertile land. [0003] When burning bricks, the combustibles of gangue itself can ...

AI Technical Summary

Problems solved by technology

[0003] When burning bricks, the combustibles of gangue itself can be used to save coal. Coal gangue needs to be dried during the processing and production process. The existing coal gangue drying device has a complex structure and many drying processes, which affects the processing efficiency. , so it is necessary to invent a coal gangue drying device to solve the above problems
