Description

Vibration drum screen equipment

Technical Field

The utility model relates to a material separation technical field especially relates to a section of thick bamboo sieve equipment shakes.

Background

The screening machine is a mechanical device used for sorting various raw materials and various primary products into a plurality of grades according to the granularity of the materials by using the actions of rotation, vibration, reciprocation, shaking and the like, or removing moisture, impurities and the like in the raw materials and the primary products, and then carrying out the next processing and improving the product quality.

The drum screen is a machine widely applied in the sorting technology, controls the sorting of garbage by controlling the particle size of particles, and has high sorting precision. The drum body of the drum screen is generally divided into a plurality of sections, the screen holes are arranged from small to large according to specific conditions, and the aperture of each section of screen hole is the same.

The commonly used drum screen mainly comprises a motor, a speed reducer, a drum device, a frame, a sealing cover and a feeding and discharging port.

The roller device is obliquely arranged on the frame. The motor is connected with the roller device through the speed reducer and the shaft coupling, and drives the roller device to rotate around the axis of the roller device. After the materials enter the roller device, the materials on the screen surface are overturned and rolled due to the inclination and rotation of the roller device, so that the qualified materials (undersize products) are discharged through a discharge hole at the bottom of the rear end of the roller, and the unqualified materials (oversize products) are discharged through a discharge hole at the tail part of the roller. Because the material is upset, the roll in the cylinder, make the material of card in the sieve mesh can be popped out, prevent that the sieve mesh from blockking up.

However, in the prior art, when the drum sieve is used for sorting garbage materials, due to the fact that the materials are wet and the number of strip-shaped materials is large, the phenomenon of hanging and blocking holes easily occurs on sieve holes (particularly coarse sieve holes of a coarse sieve plate) due to rotation. Great inconvenience is brought to the manual cleaning of the roller at regular time.

the woven mesh screen is arranged in the vibrating screen body; the vibrating screen body is fixed through the screen mesh supporting frame; and a feeding chute is arranged at the feeding end of the rotary screen 1.

And a material receiving hopper for receiving materials is arranged below the rotary screen 1.

And a bottom support for supporting the drum screen is arranged below the drum screen 1.

The beating device 3 is arranged on a support above the drum screen 1, and the support is longitudinally parallel to the drum screen 1.

The distance of the bracket from the drum screen 1 is set so that the striking device 3 can strike the drum screen 1 and vibrate the drum screen 1.

The support is a rigid beam structure or a suspension cable structure.

The striking device 3 is of rigid construction.

The utility model has the advantages that:

in this embodiment, hit the device through beating and hit the drum sieve of beating in service to make the drum sieve produce the vibration, avoid tiny material to block up the sieve mesh, sieve the operation. Meanwhile, the vibration source can drive the drum screen to vibrate, and the drum screen can vibrate to avoid blocking screen holes. And the flexible connection between the transmission device and the rotary screen ensures that the vibration of the rotary screen does not influence the normal operation.

In this embodiment, a section of thick bamboo sieve equipment that shakes can clear up the sieve automatically at the during operation, reduces the stifled hole of sieve, improves work efficiency.
