Coal mine screening equipment with dewatering function

Abstract

The invention provides coal mine screening equipment with a dewatering function. The equipment comprises a protective cover, a motor, a connecting rod, a second groove, an electric telescopic rod, a box body, a third groove, reset springs and a rubber pad; the protective cover is assembled at the right end of a coal outlet pipe, the motor is assembled at the right end inside the protective cover,and the connecting rod is assembled at the left end of the motor, so that the purpose of conveniently and rapidly maintaining the coal outlet pipe of the equipment is achieved through the design; andthe second groove is formed in the right end of a base, the electric telescopic rod is assembled at the left end of the interior of the second groove, the box body is assembled at the right end of theelectric telescopic rod, and is arranged in the second groove, the reset springs are assembled at the lower end of the interior of the box body, the upper ends of the reset springs extend to the upper side of the box body, the rubber pad is assembled at the upper ends of the reset springs, and the third groove is formed in the lower end of the box body, so that the purpose of reducing the coal fragmentation amount is achieved through the design. The equipment is convenient to clean, capable of reducing impact force, complete in function, and safe and reliable.

Description

technical field [0001] The invention is coal mine screening equipment with dehydration function, which belongs to the field of coal production equipment. Background technique [0002] The trommel screen is a kind of machine widely used in the separation technology. It controls the coal sorting through the size of the particle size. The separation accuracy is high. The cylinder of the trommel screen is generally divided into several sections, depending on the specific situation. , the sieve holes are arranged from small to large, and the sieve holes on each section have the same diameter. The drum screen mainly consists of a motor, a reducer, a drum device, a frame, a sealing cover, and an inlet and outlet. In order to improve the sorting accuracy, in order to avoid small When the granular material is screened out in the large-aperture screening section, the coal must be fully turned over in the drum screen, and the moving speed of the garbage should not be too fast.

AI Technical Summary

Problems solved by technology

[0003] The existing coal mine screening equipment cannot clean the dust in the coal discharge pipe while protecting the coal discharge pipe, cannot reduce the workload of the staff, and lacks a buffer function after the coal is screened out, so a new type of coal mine screening with dehydration function is urgently needed equipment to solve the above problems
