Description

Driving transmission structure for rotary drum screen

Technical Field

The utility model relates to a drum sieve technical field, concretely relates to drum gyratory sieve is with drive transmission structure.

Background

The drum sieve is also called as rotary drum sieve, the sieve surface of the drum sieve is a cylindrical drum with holes, the working surface of the drum sieve is formed by arranging a plurality of rotary rollers, the shafts are provided with plates, and the drum sieve can be divided into a disc drum sieve and a special disc drum sieve according to different shapes of rotors.

The openings of the trommel screen are formed by the spaces between adjacent rollers and adjacent discs. During operation, the screen drum is driven by the transmission device to slowly rotate around the shaft, solid waste is fed from one end of the screen drum and is carried by the rotating drum, the solid waste automatically falls under the action of gravity after reaching a certain height, and the solid waste continuously rises and falls, so that materials fed to the screen surface gradually move towards the discharge end due to the rotation of the roller, fine particles smaller than the size of the screen holes penetrate through the screen, the screening effect is obtained, products on the screen gradually move to the other end of the screen to be discharged, and in order to enable the waste drum to advance along the axis direction, the line of the screen drum is required to incline by 3-5 degrees during installation.

The drum sieve is often used in the operation of coarse screening material (hole is greater than 15 mm), and is compared with fixed sieve, and screening efficiency is higher, and screening effect is good, and required mounting height is less, and the maintenance is simple and convenient. Although the structure of the screen is firm and reliable and has no unbalanced part, the screen is only widely used in coal preparation plants and iron works at present due to the complex structure, the screening efficiency is higher, and the roller screen is also used as a feeder besides a screen. Has the effect of one machine for two purposes, and can save investment cost.

The prior patent No. CN201820676520.8 is named as a patent of a roller screen, and the patent is that the roller screen is provided with a first air supply mechanism and a screening roller capable of rotating, so that the dispersibility of materials can be improved, the aggregation of the materials can be reduced, and the screening effect and efficiency on light fiber materials can be improved under the double actions of wind energy and centrifugal force; through setting up with screening rotary drum roll connection's supporting mechanism both can improve the pivoted stability of screening rotary drum, also can reduce the wearing and tearing of screening rotary drum, improve whole device's life.

But this patent only drives the screening bucket through the motor and sieves, and then the material after the screening is allocated out through the discharge gate. Easily causing the blockage of the discharge hole. Meanwhile, large heavy materials are accumulated at the bottom to block the discharge hole, so that the screening of the materials is hindered.
