Abstract
In the technical field of screening pellet of the present invention, can solve the accurate running problem of high output by a kind of screening plant, this equipment comprises a box housing (2) that diminishes gradually to the bottom, be useful on the valve member (3) of control waste outlet (4) in the bottom, have a straight screen cloth to stretch tight on framework (6) in enclosure interior.This screen cloth laterally is placed in the cylindrical import (7), material to be sieved is by one pneumatic floating that is caused by pressure or vacuum, inwall at housing (2) forms wall one, and on the wall outlet (8) of a columniform conduct through the screening material arranged over there, a kind of device (9) of clearing up screen cloth top and downside is housed on screen cloth, also has at least one fan to be used to overhaul the access door (21) of enclosure interior.
Description
The present invention relates to a kind of screening plant that is used for granule materials such as cereal and so on.
The fine graded material of plant-scale screening need fast accurately running, simple in structure, seldom to keep in repair and the effective equipment of high yield can be provided.
The objective of the invention is to be used for fine graded material as cereal and so on, especially for the mill continued operation screening plant of disintegrating process process of factory and cereal processing factory of pulverizing, to reach above-mentioned target by providing a kind of.This equipment itself or just can provide optimum operation usefulness with other similar devices is supporting, corollary equipment comprises the equipment that a whole set of is applicable to the factory's production capacity of generally milling.
This or other purpose system is reached by the screening plant that is used for granule materials such as cereal and so on, and it is characterized in that: it comprises a box housing, diminishes gradually to the bottom, valve member is set with the control waste outlet in the bottom; There is a straight screen cloth to stretch tight on the framework in angle of inclination may in enclosure interior, described screen cloth occupy in the columniform import across, pneumatic floating by one material to be sieved that is caused by vacuum or pressure, inwall at housing forms wall one, and on the wall outlet of a columniform conduct through the screening material arranged over there, a kind of device of clearing up described screen cloth top and downside is arranged on screen cloth, also have at least one fan to be used to overhaul the access door of enclosure interior.
The features and advantages of the present invention from following to the equipment that is used for sieving granular material such as cereal and so on one preferable but the detailed description of closing not exclusive embodiment just see obviously.This embodiment but is not limited to accompanying drawing as shown in drawings.In the accompanying drawing:
Fig. 1 be one according to the present invention the schematic diagram and the part sectioned view of screening plant;
Fig. 2 is the cutaway view of the I-I line along Fig. 1.
With reference to above-mentioned accompanying drawing, numbering 1 is briefly represented the screening plant of a continued operation, the mensuration that is used for the fine graded material or the fine granular material of cereal and so on particle, it comprises one to diminishing box housing 2 in bottom and the control valve parts 3 that are used to control a waste outlet 4, and this valve comprises the valve 5 of a what is called " star " type.One straight screen cloth is arranged in housing 2, do not express in the accompanying drawings, stretch tight on the framework 6 of angle of inclination may, the import 7 that framework 6 places material to be sieved columniform, that by pneumatic floating with screen cloth, outlet 8 and described import 7 constitute the metope arranged side by side of housings 2, and the axis of the level of being roughly is arranged.
Have screen cleaning device 9 on the framework 6 Screening Network parts, comprise adorning above one cross bar 10a, at the rectangle sub-frame 10 at top, sub-frame 10 links to each other to be driven with hydraulic shift cylinders 11 and reciprocatingly slides, the piston 12 of hydraulic shift cylinders 11 links to each other with at least one cross bar 10a, when reciprocatingly sliding, by parallel with framework 6 near operation spray washing agent or compressed air on Screening Network of a plurality of nozzles 13, and each nozzle is connected each other and link to each other with feeder sleeve 14.Under the framework 6 Screening Network parts.Screen cleaning device 9 comprises the outside small brushes 15 of a cover mane, is contained on the gypsy chain 16, and driving-chain 16 is driven by sprocket wheel 17, and one is a driving wheel, and another is a driven pulley, and there is a regulating wheel 18 at driving-chain 16 middle parts.
The inner end that should be noted that the cylindrical outlet 8 that is used to sieve material is made of the infundibulate enlarging 19 towards housing 2 inside, and its part is hidden by the throttling dividing plate 20 of outlet 8, and housing 2 also has at least one fan to be used to overhaul its inner access door 21.
The operation of this equipment (process) is as follows: material to be sieved is used make its air-flow that has suspended introduce cylindrical import 7, as shown by arrow A.Obviously, any method of a kind of like this air-flow of available formation is for example used ventilation blower, air blast or compressor.
Material is sprayed on the Screening Network that is being supported by framework 6, and framework 6 is installed to such an extent that can make reciprocally swinging, and can place a suitable angle to provide one at as calculated inclination angle between itself and the material jet (arrow B).
Then, through the screening the thrust of a large amount of materials in said flow under by cylindrical outlet 8(arrow C) draw, its amount also can be by dividing plate 20 controls, and the remaining bottom that diminishes gradually that does not fall to housing 2 by the amount of screen cloth is measured and is delivered to further treatment process or makes other purposes with valve member 3.
Should be noted that this box housing can make favourable shape so that screening plant can be supporting with other similar devices, comprise some similar devices in unit, each device respectively is equipped with the Screening Network of different sieve meshes so that the screening system of the high ability of a cover to be provided.
Find that in practice invention described herein can reach aforementioned purpose fully.
In addition, the present invention is easy to do many remodeling and improvement in same inventive concept.
And equivalent elements replaces on described all (part) equal available techniques.
When enforcement was of the present invention, used material and size all can be decided on demand, but do not surmount the protection domain of following claim.
