Abstract

The invention relates to the field of production equipment and discloses a multistage cylinder material screening machine. The machine comprises a drive unit, a cylinder, a main bracket and a load bearing device. A discharge end of the cylinder is provided with multistage ladders, diameter of each ladder decreases gradually, each ladder is provided with a wire screen perpendicular to the axis of the cylinder, and aperture of the wire screen also decreases along with decreasing diameter. The axis is arranged on the main bracket at a certain angle relative to the horizontal plane while arranging the cylinder and driven by a motor to rotate. Materials are discharged from the top of the wire screen of each stage while being screened. The multistage cylinder material screening machine solves technical problems of high noise, high energy consumption, easy blocking the wire screen and the like in the prior art.

Description

Multistage cylinder material screening machine
Technical field
The present invention relates to the production equipment field, relate in particular to a kind of production equipment that granular material sorts that is used for.
Background technology
Sieve material technology is the technical process that granular material is sorted according to different particle diameters.Just understand that ancient age people being woven into sieve with the thin bamboo strip is used to sort things such as sand, paddy.
Along with continuous advancement in technology, people have also developed the material screening machine of automation.At present general automatic material screening machine structure is: a screen cloth is installed in the middle of the container, and entire container shakes under the effect of eccentric motor, and the material that particle is little flows out from the container below by screen cloth, and the material that particle is big flows out from the screen cloth top.There is following defective in prior art:
1, once can only sort a kind of material of specification, sort the production of plurality of specifications product, need multiple devices just can finish the work of sieve material, mean the increase of manufacturing cost for needs.
2, material stops up mesh easily on screen cloth, forms material and flocks together, and damage screen cloth easily.
3, noise is big.Vibrations are roots of sound generating, and the automatic material screening machine of prior art relies on vibrations to sort material, will produce very big noise certainly, and is very serious to operating personnel's injury.
4, effective utilization rate of energy is low.The automatic material screening machine of prior art utilizes the power source of eccentric motor as vibrations.Electric energy changes into the rotation of motor, does not directly change into the vibrations of material screening machine but rotate, but relies on eccentric horizontal level to move the vibrations that cause material screening machine.
5, dust from flying.The dust from flying that vibrations produce causes operating personnel's occupational disease easily.
Summary of the invention
The technical problem to be solved in the present invention is to develop a kind of operation principle and the diverse material screening machine of prior art material screening machine, fundamentally overcomes the defective of prior art.
The structure of multistage cylinder material screening machine of the present invention comprises drive unit, cylinder, main body rack, negative pressure device, and cylinder is installed on the main body rack and drives rotation by drive unit, and negative pressure device is connected with cylinder by pipe and in the inner chamber formation negative pressure of cylinder.The equal opening in cylinder two ends; Feed end diameter maximum, and a door that opens and closes easily is installed; Discharge end is provided with one-level ladder at least, and every grade of step diameter is step by step and reduces.A screen cloth vertical with cylinder axis is installed on every grade of ladder, and along with reducing of diameter, the aperture of screen cloth also reduces.On the cylinder wall between screen cloth and the upper level screen cloth, be provided with a breach and be connected, fail to flow out from discharging opening by the material of screen cloth with discharging opening.Cylinder axis with respect to the horizontal plane is installed on the main body rack at an angle, charging aperture up, the cylinder after the installation can freely rotate.Drive unit comprises the motor and speed reducer structure, and the direct head roll of reducing gear rotates.Negative pressure device is connected in the cylinder by pipe, makes and forms certain negative pressure in the cylinder.
The course of work of multistage cylinder material screening machine of the present invention is: the drive unit head roll rotates; The granular material of thickness inequality enters cylinder from the cylinder charging aperture; Material rolls on screen cloth, and the material that particle diameter is thinner passes on the screen cloth that the screen cloth mesh falls into next stage, and the material that particle is bigger flows out from the discharging opening on the cylinder wall; So through obtaining the different various materials of particle diameter after the multilevel screen screening.Negative pressure device makes the formation negative pressure in the cylinder, and dust is controlled in the cylinder.
Multistage cylinder material screening machine of the present invention adopts drum-type screening operation, avoided noise that vibrations cause and and dust from flying; Negative pressure device has further reduced dust from flying; Adopt the motor-driven cylinder to rotatablely move, improved the effective rate of utilization of electric energy, indirect saving electric energy; Screen cloth rotates having on the plane of certain angle with horizontal plane, and material is brought to behind the certain altitude in the screen cloth landing of gravity effect lower edge, forms a kind of state that rolls, and has effectively prevented the obstruction mesh; Adopt the mode of multistage screening, one-stop operation filters out the product of plurality of specifications, has improved production efficiency greatly, has reduced production cost.There are the difference of principle in the design of technical solution of the present invention and prior art, are not that those skilled in the art expect easily.And technical solution of the present invention has overcome the defective of prior art, has the obvious improvement meaning, is worth large-scale and promotes, thereby reduce the production cost of entire society.

The specific embodiment
Further specify the technical scheme of multistage cylinder material screening machine of the present invention below in conjunction with accompanying drawing.Following examples are the Pyatyi cylinder material screening machine, also can manufacture the cylinder material screening machine of secondary, three grades, level Four or other progression as required, are not considered as limiting the scope of the invention.
Fig. 1 is the overall structure schematic diagram lateral plan of multistage cylinder material screening machine of the present invention.
Fig. 2 is the overall structure schematic diagram front view of multistage cylinder material screening machine of the present invention.
Multistage cylinder material screening machine of the present invention comprises drive unit, cylinder 10, main body rack 4, negative pressure device.Main body rack 4 is cylindric, is installed on the holder 1 by hinge 2, and the axis of main body rack 4 experimental results show that with respect to the horizontal line certain angle that tilts best angle is 30 °.There is the big slightly ladder of a diameter 3 on the top of main body rack 4 and is provided with a door, and the bottom is the funnel-form diameter and diminishes gradually and be provided with discharging opening 5, discharging opening 6, discharging opening 7, discharging opening 8.Cylinder 10 is installed in main body rack 4 the insides, can freely rotate.
