(54) СЕПАРАТОР(54) SEPARATOR

1one

Изобретение относитс к устройствам дл разделени сыпучих материалов на фракции по крупности и может быть использовано в различных отрасл х промышленности.The invention relates to devices for separating bulk materials into fractions by size and can be used in various industries.

Известен сепаратор, включающий корГ (ус, , в котором установлена система решет , совершаюших возвратно-поступательные колебани 1.A separator is known that includes a core (mustache, in which a system of sieves is installed, performing reciprocating oscillations 1.

Недостатком его вл етс то, что крупные фракции, скаплива сь в разгрузочной зоне, затрудн ют процесс разделени материала , ухудшают его качество и производительность .Its disadvantage is that coarse fractions, accumulating in the discharge zone, impede the process of material separation, impair its quality and productivity.

Наиболее близким к предлагаемому по технической сущности вл етс устройство дл разделени сыпучих материалов на фракции по крупности, включающее корпус, раму с сеткой, установленную в корпусе с возможностью возвратно-поступательного движени , привод, св занный с рамой, пневмозаборник крупной фракции, узлы загрузки и разгрузки материала 2.The closest to the proposed technical entity is a device for dividing bulk materials into fractions by size, including a housing, a frame with a grid installed in a housing with the possibility of reciprocating motion, a drive associated with the frame, a large-scale air intake unit, loading units and unloading material 2.

Недостатком его вл етс то, что пневмозаборник осушествл ет вывод крупной фракции , забира при этом и часть мелкой. Кроме того, посто нный режим работы пневмозаборника увеличивает расход энергии, такThe disadvantage of it is that the air intake unit carries out the withdrawal of a large fraction, while taking part of it into a small fraction. In addition, the constant operation of the air intake increases energy consumption, so

как пневмозаборник помимо целенаправленного вывода крупной фракции производит забор воздуха из окружаюшей среды.as a pneumatic intake, in addition to the targeted withdrawal of a large fraction, it takes air from the environment.

Цель изобретени - повышение качества разделени .The purpose of the invention is to improve the quality of separation.

5Поставленна цель достигаетс тем, что5 The goal is achieved by the fact that

сепаратор, содержаш.ий корпус, раму с сеткой , установленную в корпусе с возможностью возвратно-поступательного движени , привод, св занный с рамой, пневмозаборник крупной фракции, узлы загрузки и разгрузки материала, снабжен подпружиненной заслонкой и профилированным копиром. Заслонка шарнирно закреплена на раме в зоне пневмозаборника, а копир закреплен на корпусе . Заслонка выполнена в виде двупле15 чего рычага, одно плечо которого св зано с копиром.the separator, the housing, the frame with the grid installed in the housing with the possibility of reciprocating motion, the drive associated with the frame, the large-scale air intake, the material loading and unloading units, is equipped with a spring-loaded damper and a profiled copier. The flap is hinged to the frame in the area of the air intake, and the copier is fixed to the body. The flap is made in the form of a double-piece 15 of which is a lever, one shoulder of which is associated with a cam.

Заслонка св зана с копиром с помощью ролика, закрепленного на ее конце.The shutter is connected to the cam by means of a roller attached to its end.

Второе плечо заслонки, контактирующее The second shoulder flap in contact

20 с сеткой, снабжено эластичным уплотнителем .20 with a mesh fitted with an elastic seal.

Claims

FIG. 1 shows a separator, a general view; in fig. 2 - a frame with a grid and with a flap; in fig. 3 - frame with a closed flap; in fig. 4 - the same, with an open damper. Separator For bulk materials consists of a carriage 1, on which the frame 2 of the sieve is fixed, in which the grid 3 is located with a slope. On the shank of the valve 4 is fixed roller 6, the valve 4 is connected to the spring 7, and above the valve 4 is rigidly attached to the frame 2 a visor 8. In the lower part of the frame 2 at the outlet end of the grid 3 is located 9 large impurities pneumatic intake port connected by a flexible hose 10 with ejection suction 11. Copier 12 is rigidly attached to the cage of the separator, and roller 6 of the flap 4 is spring pressed to copier 12. In the upper part of the cage of the separator above the frame 2 of the sieve is a hopper feeder 13. The carriage of the separator 1 is connected to the crank drive 14. Ai separator is as follows. The impurity material is supplied from the feeder hopper 13 to the grid 3 and is subjected to separation. The carriage 1 moves in a reciprocating cycle, large particles roll down the grid 3 to the window of the pneumatic intake 9 by inertia. As the carriage 1 moves, the roller 6 of the valve 4, moving along the copier, opens it and thus allows large particles to roll into “About the air intake 9. Then they will not fall into the intake 9, since it is located under the ANGLE with respect to the grid 3, and since the valve 4 is open, the degree of dilution in the intake 9 disappears and in this position of the carriage 1 the particles will not be sucked out . In the reverse movement of the carriage 1, the roller 6 of the flap 4, moving back along the copier 12, will close the inlet window 9 with the help of the spring 7 by the damper 4 and simultaneously will burn the collected particles. There will be a suction of particles in the bunker. In such a sequence, large impurities will be removed during the operation time of the separator. The use of the proposed separator improves the quality of material separation, due to the directional withdrawal of coarse fractions, and also improves the efficiency of the entire device, since using a damper in a pneumatic intake a closed chamber is formed, the material is removed from which it is easier to open than from an open mesh. Claim 1. A separator comprising a housing, a frame with a grid, mounted in a housing with the possibility of reciprocating motion, a drive, a large fraction pneumatic intake box, a material loading and unloading unit, characterized in that, in order to increase the quality of separation, the separator is equipped with a spring-loaded damper, hinged to the frame in the area of the air intake, and a profiled copier fixed to the body, while the damper is made in the form of a two-arm lever, one arm of which is connected to the copier ohm 2. A separator according to claim 1, characterized in that the shutter is connected to the cam by means of a roller attached to its end. 3. A separator according to claim 1, characterized in that the second flap shoulder is provided with an elastic seal. Sources of information taken into account during the examination 1.
