Parabolic roller type screening machine based on raw coal screening

Abstract

The invention provides a parabolic roller type screening machine based on raw coal screening. The parabolic roller type screening machine comprises a conveying pipe, a hollow sleeve rod, a rotary rod, a first circular gear, a motor, a second circular gear, a third circular gear, a lamp plate, a first electric cylinder, a top cover and an elastic hinge. The hollow sleeve rod is arranged at the lower end of the conveying pipe. The rotary rod is assembled to the hollow sleeve rod. The first circular gear is fixed to the rotary rod. The second circular gear is arranged at the right end of the third circular gear. The second circular gear is arranged at the front end of the motor. By means of the design, the conveying pipe can be disassembled or assembled, the lamp plate is arranged at the lower end of the top cover, the lower end of the top cover is provided with the elastic hinge, the first electric cylinder is fixed to the lower end of the top cover and installed on the right side of the lamp plate, the top of the screening machine can be opened and closed through the design, and the parabolic roller type screening machine is convenient to use, capable of saving time and labor, and good in stability and using effect.

Description

technical field [0001] The invention relates to a parabolic roller type screening machine based on raw coal screening, which belongs to the technical field of raw coal screening. Background technique [0002] In the prior art, since the beginning of the 21st century, the demand for coal products has been too large, leading to a shortage of coal resources. Raw coal refers to coal that is mined from the ground and only selects visible gangue without any processing. In my country, 80% of gangue-containing materials supplied to users are raw coal, which has a high ash content and gangue-containing rate. Containing many harmful impurities, direct combustion of raw coal not only has low utilization rate, but also pollutes the environment, so the screening of raw coal becomes very important. [0003] The feeding pipe of the existing screening machine cannot be disassembled. It is necessary to use the feeding pipe for feeding when carrying out large-scale raw coal screening, and it...

Contains many harmful impurities, direct combustion of raw coal not only has low utilization rate, but also pollutes the environment, so raw coal screening becomes very important

[0003] The feeding pipe of the existing screening machine cannot be disassembled. It is necessary to use the feeding pipe for feeding when carrying out large-scale raw coal screening, and it is not necessary to use the feeding pipe for experimental raw coal screening. The material conveying pipe causes the staff to perform experimental raw coal screening or large-scale raw coal screening on different machines. Installing the upper cover consumes a lot of time and manpower. The filter screen of the existing screening machine cannot be replaced. When the filter screen is damaged, the machine can only be replaced, resulting in waste
