Abstract

The invention relates to a screening and separating machine for granular materials, which comprises a feed hopper, an internal screen drum, an external screen drum, a rotating shaft, a tail discharge hopper, a lateral discharge hopper, a bottom discharge hopper and a dust hood, wherein the internal and external screen drums are provided with screen holes or screen cloth, and the feed hopper is communicated with the internal screen drum; the internal screen drum is positioned in the external screen drum and is connected to a rotating shaft together with the external screen drum; the tail discharge hopper is arranged below the tail part of the internal screen drum; the lateral discharge hopper is arranged below the tail part of the external screen drum; the bottom discharge hopper is positioned below the external screen drum and the internal screen drum; and the upper parts of the internal and external screen drums are positioned in the dust hood. The machine has the advantages that: mechanical operation is realized; various metal or non-metal materials with different particle sizes can be screened and separated at one time; the working efficiency is high; less workers are needed; the production cost is reduced; the design is reasonable; the noise is low; dust rise is avoided basically; and environmental-protection and production requirements are met.

Description

A kind of screening and separating machine of granular material
Affiliated technical field
The present invention relates to a kind of screening and separating machine of granular material.
Background technology
In enterprise production process, often metal or non-metallic particle shape material need be carried out sorting according to its granularity.Usually the Apparatus and method for of taking is: utilize flat screen or support roller transmission sieve, metal or non-metallic particle shape material are placed on the screen cloth of different silk density, segmentation distributes, and screens again and again, and could classify obtains the material of variable grain degree.These noise of equipment are big, and dust is many, and separation velocity is slow, and can not carry out the mechanization pipelining.
Summary of the invention
The purpose of this invention is to provide the disposable screening of energy and isolate the screening and separating machine of a kind of granular material of multiple variable grain degree.
The technical scheme that the present invention takes is: a kind of screening and separating machine of granular material, comprise feed hopper, interior screen drum, outer screen drum, power transmission shaft, afterbody discharge bucket, avris discharge bucket and bottom discharge bucket, interior screen drum and outer screen drum are provided with sieve aperture or screen cloth, it is characterized in that feed hopper and interior screen drum are connected, and be positioned at the front end of screen drum and outer screen drum; Interior screen drum is positioned at outer screen drum, and interior screen drum is connected on the power transmission shaft with outer screen drum; The below of screen drum afterbody in the afterbody discharge bucket is arranged on; The avris discharge bucket is arranged on the below of outer screen drum afterbody; The bottom discharge bucket is positioned at the bottom of outer screen drum and screen drum.
It also includes dust shield the screening and separating machine of described a kind of granular material, and interior screen drum is positioned at wherein with the first half of outer screen drum.
The length of screen drum cylindrical shell is greater than 5~40 centimetres of the length of outer screen drum cylindrical shell in described.
Sieve aperture or screen cloth in described on the screen drum, and should remain on 5~50 centimetres spacing between sieve aperture on the outer screen drum or the screen cloth.
The horizontal sextant angle of described feed hopper and afterbody discharge bucket remains between 15~20 °.
Adopt the present invention, not only realized the mechanization operation, can disposable screening isolate multiple variable grain degree metal or non-metallic material, high efficiency, reduced manually, reduced production cost, and reasonable in design, noise is little, dust raising phenomenon can not occur substantially, meets the environmental protection production requirement.
Description of drawings
Fig. 1 is a schematic diagram of the present invention.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
With reference to Fig. 1, this screening and separating machine comprises feed hopper 1, interior screen drum 2, outer screen drum 3, power transmission shaft 4, afterbody discharge bucket 7, avris discharge bucket 8, bottom discharge bucket 9, interior screen drum 2 and outer screen drum 3 are provided with sieve aperture 5 (also can be screen cloth certainly), feed hopper 1 is connected with interior screen drum 2, and is positioned at the front end of screen drum 2 and outer screen drum 3; Interior screen drum 2 is positioned at outer screen drum 3, and interior screen drum 2 is connected on the same power transmission shaft 4 with outer screen drum 3; The below of the afterbody of screen drum 2 in afterbody discharge bucket 7 is arranged on; Avris discharge bucket 8 is arranged on the below of the afterbody of outer screen drum 3; Bottom discharge bucket 9 is positioned at the bottom of outer screen drum 3 and screen drum 2.Dust shield 6 covers on the first half of interior screen drum 2 with outer screen drum 3 wherein.
The length of above-mentioned interior screen drum 2 cylindrical shells is greater than 5~40 centimetres of the length of outer screen drum 3 cylindrical shells, by this gap design, the separation screening degree of particle reached more than 95% excessive the or too small halfway state of separation screening that all will produce of difference.The internal diameter of the external diameter of screen drum 2 and outer screen drum 3 in above-mentioned, the sieve aperture 5 (or screen cloth) on the promptly interior screen drum 2 and the spacing of the sieve aperture 5 (or screen cloth) on the outer screen drum 3 should remain between 5~50 centimetres, and the separation screening effect that meets this separation criteria is best.Horizontal sextant angle after above-mentioned feed hopper and afterbody discharge bucket are installed should remain between 5~20 °, and this angle is the most favourable by separation screening smoothly to granular materials.
During use, starter motor, interior screen drum 2 and outer screen drum 3 rotate with power transmission shaft 4, pour feed hopper 1 into when the metal that will need separation screening or non-metallic particle shape material, and granular material is introduced into interior screen drum 2, rotation in interior screen drum 2, and it is under the effect of rotary centrifugal force, will progressively separate to enter outer screen drum 3 than the 5 little particles of the sieve aperture on the interior screen drum 2, and bigger than the sieve aperture 5 on the interior screen drum 2, also be that maximum particle is wriggled inside screen drum 2 afterbodys, and discharge from afterbody discharge bucket 7; The particle that enters outer screen drum 3 will screen again, and bigger particle is with the afterbody wriggling of outside screen drum 3, and from 8 discharges of avris discharge bucket, minimum particle will and fall into bottom discharge bucket 9 from outer screen drum 3 screenings; Like this with regard to disposable metal that filters out three kinds of specifications or non-metallic particle material.In the screening separating process, can produce very big airborne dust, airborne dust is upwards kicked up, and siphons away by dust shield 6, reaches the environmental protection purpose.
