Description

Изобретение относится к хранению и перегрузке сыпучих материалов и может быть использовано для перегрузки пылевидных материалов.The invention relates to the storage and transshipment of bulk materials and can be used for transshipment of pulverulent materials.

По основному авт. св. » 587068 известно устройство для разгрузки сыпучих материалов из бункера с горизонтальной выпускной щелью, содержащее поворотные клапаны, установленные в щели, перемещающийся вдоль щели механизм открытия и закрытия клапанов и приемный ленточный конвейер, причем упомянутый механизм смонтирован на подвижной тележке, снабженной рамой с роликами, которые огибает рабочая ветвь ленты конвейера. Кроме того, тележка снабжена механизмом подъема рамы.According to the main author. St. "587068, there is known a device for unloading bulk materials from a hopper with a horizontal outlet slit, comprising rotary valves installed in the slit, a valve opening and closing mechanism moving along the slit, and a receiving belt conveyor, said mechanism being mounted on a movable trolley equipped with a frame with rollers, which goes around the working branch of the conveyor belt. In addition, the trolley is equipped with a frame lifting mechanism.

Недостаток известного устройства заключается в том, что использование рамы с роликами в указанном положении не обеспечивает равномерного выпуска материала из бункера вдоль выпускной щели, а наличие зазора между полотном ленты и выпускной щелью по торцовой стороне рамы не позволяет исключить просыпание материала, являющегося источником интенсивного пылеобразования.A disadvantage of the known device is that the use of a frame with rollers in the indicated position does not ensure uniform discharge of material from the hopper along the outlet gap, and the presence of a gap between the tape web and the outlet gap on the end side of the frame does not preclude the spillage of material, which is a source of intense dust formation.

Цель' изобретения — повышение эффективности выгрузки материала и уменьшение пылеобразования.The purpose of the invention is to increase the efficiency of unloading material and reduce dust formation.

с Это достигается тем, что рама с ^э роликами имеет наклонный в сторону движения материала промежуточный участок.This is achieved with the fact that the frame has rollers with ^e oblique to the direction of motion of the material portion in between.

На фиг. 1 показано предлагаемое устройство, вид сбоку; на фиг. 2 — ^υ разрез А-А фиг. 1.In FIG. 1 shows the proposed device, side view; in FIG. 2 - ^υ section AA of FIG. 1.

Устройство содержит бункер 1 с го ризонтальной выпускной щелью 2, в ко торой на осях 3 установлены поророт'ные клапаны 4. Под щелью 2 располо15 жен приемный конвейер 5, на котором установлена подвижная тележка 6, снабженная наклонной рамой 7 с роликами 8, которые огибает рабочая ветвь 9 ленты конвейера 5. При этом 20 между лентой и выпускной щелью 2 имеется зазор 10 с возможностью его увеличения в сторону движения¹ ленты. На тележке 6 смонтирован механизм открытия и закрытия клапанов 4 в 25 виде копирного упора 11, взаимодействующего с рычагами 12 осей 3. Тележка 6 снабжена механизмом 13 подъе ма рамы 7, Рама с роликами имеет наклонный в сторону движения материа 30 ла промежуточный участок 14.The device comprises a hopper 1 with a horizontal outlet slit 2, in which porous valves 4 are mounted on the axles 3. Under the slot 2 there is a receiving conveyor 5, on which a movable trolley 6 is installed, equipped with an inclined frame 7 with rollers 8 that surrounds the working branch 9 of the conveyor belt 5. At the same time, 20 between the belt and the outlet slot 2 there is a gap 10 with the possibility of its increase in the direction of movement ^{1 of the} belt. A mechanism for opening and closing valves 4 in 25 is mounted on a trolley 6 in the form of a carbon stop 11, which interacts with the levers 12 of the axles 3. The trolley 6 is equipped with a mechanism 13 for lifting the frame 7, the frame with rollers has an intermediate section 14 inclined toward the direction of movement of the material 30 la.

Работает устройство следующим об·¹· разом. При перемещении ‘тележки б вдоль конвейера 5 открывается клапан 4, расположенный непосредственно над тележкой 6, и материал высыпается из бункера 1 на рабочую ветвь 9 ленты, которая благодаря наклонной раме 7 с роликами 8 максимально приближается к выпускной щели 2 с передней торцовой стороны рамы по ходу движения ленты, а противоположная сторона раьы имеет зазор 10 между выпускной щелью 2 бункера и лентой конвейера, обеспечивающий заданную производительность выпуска. Благодаря этому достигают равномерного выпуска материала вдоль выпускной щели и исключают просыпание материала с передней торцовой стороныThe device operates as follows · ¹ · at a time. When moving the trolley b along the conveyor 5, the valve 4 opens directly above the trolley 6, and the material pours out from the hopper 1 onto the working branch 9 of the belt, which, thanks to the inclined frame 7 with rollers 8, is as close to the outlet slit 2 from the front end side of the frame along the movement of the belt, and the opposite side of the paradise has a gap 10 between the outlet slot 2 of the hopper and the conveyor belt, providing a given output performance. Due to this, a uniform release of material along the outlet gap is achieved and spillage of material from the front end side is excluded

Claims

The invention relates to the storage and handling of bulk materials and can be used for reloading dusty materials. According to the main author. St. No. 587068 and a device for unloading bulk materials from a hopper with a horizontal outlet slit, comprising rotary valves mounted in the slit, a valve opening and closing mechanism moving along the slit and a receiving conveyor belt, the said mechanism mounted on a movable carriage equipped with a frame rollers, which bends around the working branch of the conveyor belt. In addition, the trolley is equipped with a frame lifting mechanism. A disadvantage of the known device is that the use of a frame with rollers in said position does not ensure uniform release of material from the hopper along the discharge slot, and the presence of a gap between the belt web and the discharge slot on the front side of the frame does not allow for the spillage of material a source of intensive schle formation. target; invention - improving the efficiency of discharging the material and reducing dust generation. This is achieved in that the frame with the rollers has an intermediate section inclined in the direction of movement of the material. FIG. 1 shows the proposed device, side view; in fig. 2 - section A-A of FIG. 1. The device comprises a hopper 1 with a horizontal exhaust slot 2, in which rotary valves 4 are installed on the axles x 3. Under the slit 2 is a receiving conveyor 5, on which is mounted a mobile carriage 6, equipped with an inclined frame 7 with rollers 8, which bends around the working branch 9 of the conveyor belt 5. At the same time, there is a gap 10 between the belt and the discharge slot 2 with the possibility of increasing it in the direction of the belt movement. On the trolley 6, the mechanism for opening and closing the valves 4 is mounted in the form of a copy stop 11, which interacts with the levers 12 of the axles 3. The trolley 6 is equipped with a ragla lifting mechanism 13 7. The frame with rollers has an intermediate section 14 inclined in the direction of material movement. When moving the carriage 6 along the conveyor 5, the valve 4 opens directly above the carriage b, and the material is poured out of the hopper 1 to the working branch 9 of the belt, which due to the inclined frame 7 with the rollers 8 approaches the outlet slot 2 from the front end side of the frame along the way belt movement, and the opposite side has a gap of 10 between the outlet slot 2 bunkers and a long conveyor belt, which ensures a given output capacity. Due to this, a uniform release of material is achieved along the discharge slit and excludes waking of 4 material from the front face of AMA, thereby reducing dust formation when the material is poured out. With the encouragement of the mechanism 13, the gap between the gap 2 and the working branch 9 is adjusted. Formula of the invention A device for unloading bulk materials from a hopper with a horizontal discharge slot according to the author. St. No. 587068, characterized in that, in order to increase the efficiency of material unloading and reduce dust generation, the frame with rollers has an intermediate section inclined in the direction of material movement.
