Description

Изобретение относится к хранению и выдаче сыпучих материалов, в частности металлических порошков, в установках для нанесения износостойких .покрытий.The invention relates to the storage and dispensing of bulk materials, in particular metal powders, in installations for applying wear-resistant coatings.

По основному авт. св. № 636140. известен бункер для хранения и выдачи сыпучих материалов, содержащий емкость с коническим днищем, внутри которой размещен затвор с запирающим механизмом, при этом запирающий меха- . низм выполнен в виде цанги, разжимная втулка которой по наружной поверхности покрыта эластичной оболочкой, а внутри выполнена с конической поло- 15 стью, в которой расположен подпружиненный шток [1] .According to the main author. St. No. 636140. A hopper for storing and dispensing bulk materials is known, containing a container with a conical bottom, inside which a shutter with a locking mechanism is placed, while the locking mech. The lower part is made in the form of a collet, the expanding sleeve of which is covered with an elastic shell on the outer surface, and inside it is made with a conical cavity 15 in which a spring-loaded rod is located [1].

Недостатком этого устройства является интенсивный износ наружной по- 20 верхности эластичной оболочки, в нижней части контактирующей с кромкой конического днища, в результате чего оболочку периодически приходится заменять, хотя в верхней части она праю25 тически не изнашивается. Это в свою очередь снижает надежность устройства *и приводит к тому, что значительное количество доброкачественного материала уходит в отходы. 30The disadvantage of this device is the intensive wear of the outer surface of the elastic shell, in the lower part in contact with the edge of the conical bottom, as a result of which the shell has to be replaced periodically, although in the upper part it does not practically wear out. This in turn reduces the reliability of the device * and leads to the fact that a significant amount of benign material goes to waste. thirty

Цель изобретения - повышение надежности устройства.The purpose of the invention is to increase the reliability of the device.

Данная цель достигаетФя тем, что бункер снабжен эластичным уплотнительным кольцом, охватывающим одновременно разжимную втулку и эластичную оболочку, на внутренней поверхности которой выполнен буртик, а на наружной поверхности разжимной втулки проточка, в которой размещен буртик.This goal is achieved by the fact that the hopper is equipped with an elastic sealing ring, covering both the expansion sleeve and the elastic shell, on the inner surface of which a shoulder is made, and on the outer surface of the expansion sleeve, a groove in which the shoulder is placed.

Бункер для хранения и выдачи сыпучих материалов содержит цилиндрическую емкость 1 с коническим днищем 2,,внутри которой размещен затвор с запирающим механизмом в виде цанги, разжимная втулка 3 которой в нижней части наружной ее поверхности покрыта эластичной оболочкойThe hopper for storing and dispensing bulk materials contains a cylindrical container 1 with a conical bottom 2, inside which there is a shutter with a locking mechanism in the form of a collet, an expandable sleeve 3 of which is covered with an elastic shell in the lower part of its outer surface

4. С целью более надежной Фиксации на внутренней поверхности эластичной оболочки 4 выполнен буртик 5, размещенный в проточке 6, выполненной на наружной поверхности разжимной втулки 3. Внутренняя поверхность втулки 3 представляет собой коническую полость, в которой расположены пружина 7 и шток 8. Емкость 1 з акрыта крышкой 9, на которой винтами 10 в кожухе 11 закреплен запирающий механизм. Кожух 11 предохраняет разжимную втулку 3 с эластичной оболочкой 4 от воздействия сил давления _ материала, находящегося в бункере. ⁵ 4. For the purpose of more reliable fixation, a shoulder 5 is made on the inner surface of the elastic shell 4 and is located in a groove 6 made on the outer surface of the expansion sleeve 3. The inner surface of the sleeve 3 is a conical cavity in which the spring 7 and the rod 8 are located. Capacity 1 C is covered with a cover 9, on which the locking mechanism is fixed with screws 10 in the casing 11. The casing 11 protects the expansion sleeve 3 with an elastic sheath 4 from the action of pressure forces _ of the material in the hopper. ⁵

В канавке 12, выполненной в нижней части полости кожуха 11, установлено эластичное уплотнительное кольцо 13, охватывающее одновременно разжимную втулку 3 и эластичную оболочку 4,,которое предназначено для предотвращения попадания сыпучего материала в полость кожуха 11. Для загрузки сыпучего материала предусмотрены загрузочные ’отверстия 14. Ход штока 8. регули- 15 руется гайкой 15, а усилие сжатия пружины 7 - втулкой 16. Бункер снабжен вибратором 17, размещенным в проеме кронштейна 18, на котором с помощью подпружиненных болтов 19 закреп- 20 лено коническое днище 2 емкости 1 бункера. Под разгрузочной кольцевой щелью, образованной кромкой конического днища 2 и наружной поверхностью эластичной оболочки 4, устанавливает- -,ся упрочняющая деталь 20, размещенная с зазором концентрично центрирующему стакану 21.In the groove 12, made in the lower part of the cavity of the casing 11, an elastic sealing ring 13 is installed, covering both the expansion sleeve 3 and the elastic casing 4, which is designed to prevent the bulk material from entering the cavity of the casing 11. For loading bulk material, loading openings 14 are provided The stroke of the rod 8. is regulated by nut 15, and the compression force of the spring 7 by sleeve 16. The hopper is equipped with a vibrator 17 located in the opening of the bracket 18, on which the conic is fixed using spring-loaded bolts 19 some bottom 2 of the container 1 of the hopper. Under the unloading annular gap formed by the edge of the conical bottom 2 and the outer surface of the elastic shell 4, a reinforcing part 20 is installed, placed with a gap to the concentric centering cup 21.

Бункер работает следующим образом.The hopper operates as follows.

На позиции загрузки исполнитель- „ ный механизм (не показан) перемещает 30 шток 8 вверх, сжимая пружину 7. При этом контактирующие поверхности штока 8 и разжимной втулки 3 выходят из взаимодействия, и разжимная втулка 3 сжимается, открывая кольцевую щель 35 в разгрузочном отверстии бункера, через которую происходит выдача сыпучего материала из емкости 1. Эластичное уплотнительное кольцо 13 разжимается, продолжая взаимодействовать 4Q своей внутренней поверхностью с наружной поверхностью втулки 3 и обо лочки 4, препятствуя попаданию сыпучего материала в полость кожуха 11. По окончании выдачи материала испол- ’ нительный механизм возвращается в исходное положение. Шток 8 под действием упругой силы сжатой пружины 7 перемещается вниз.При взаимодействии контактирующих поверхностей разжимной втулки 3 и штока 8 происходит разжим втулки 3, и,наружная поверхность эластичной оболочки 4 герметично перекрывает разгрузочную кольцевую щель. Вибратор 17 включается в момент выдачи материала и служит для предотвращения сводообразования в бункере и повышения текучести сыпучего материала. Наличие в бункере эластичного уплотнительного кольца, охватывающего одновременно разжимную втулку и эластичную оболочку, позволяет предотвратить попадание сыпучего материала во внутреннюю полость кожуха, в результате чего повышается надежность работы бункера.At the loading position, an actuating mechanism (not shown) moves the 30 rod 8 upward, compressing the spring 7. In this case, the contacting surfaces of the rod 8 and the expansion sleeve 3 are out of interaction, and the expansion sleeve 3 is compressed, opening the annular gap 35 in the discharge opening of the hopper through which the bulk material is dispensed from the container 1. The elastic o-ring 13 is expanded, continuing to interact 4Q with its inner surface with the outer surface of the sleeve 3 and the shell 4, preventing the bulk material from getting into iala cavity in housing 11. Upon completion of dispensing material ispol- 'tional mechanism returns to its initial position. The rod 8 moves downward under the action of the elastic force of the compressed spring 7. When the contacting surfaces of the expansion sleeve 3 and the rod 8 interact, the sleeve 3 is expanded, and the outer surface of the elastic shell 4 seals the discharge ring gap. The vibrator 17 is turned on at the time of delivery of the material and serves to prevent arching in the hopper and increase the flowability of bulk material. The presence in the hopper of an elastic sealing ring, covering both the expandable sleeve and the elastic shell, prevents the ingress of bulk material into the internal cavity of the casing, which increases the reliability of the hopper.

Claims

one, . The invention relates to the storage and distribution of bulk materials, in particular metal powders, in wear resistant installations. Coatings On the main auth, sv. No. 636140. A well-known hopper for storage: shade and dispensing of bulk materials, containing a container with a conical bottom, inside of which is placed a shutter with a locking mechanism, while the locking mechanism is made in the form of a collet, pa; the clamping sleeve of which is covered on the outer surface with an elastic shell , and inside is made with a conical cavity in which a spring-loaded rod 1 is located. . A disadvantage of this device is the intensive wear of the outer surface of the elastic shell, in the lower part in contact with the edge of the conical bottom, as a result of which the shell must be replaced periodically, although in the upper part it does not wear out. This in turn reduces the reliability of the device and leads to the fact that a significant amount of benign material goes to waste. The purpose of the invention is to increase the reliability of the device. This goal is achieved by the fact that the hopper is provided with an elastic sealing ring that simultaneously covers the expanding sleeve and the elastic casing, on the inner surface of which a shoulder is made, and on the outer surface of the expanding sleeve there is a groove in which the shoulder is placed. FIG. 1 shows the proposed bin in section in the open state, general view; in fig. 2 — node I in FIG. 1. The hopper for storing and dispensing bulk materials contains a cylindrical container 1 with a conical bottom 2, inside of which is placed a shutter with a locking mechanism in the form of a collet, the expandable sleeve 3 of which is covered with an elastic sheath in the lower part of its outer surface 4. For a more reliable Lick on the inner surface of the elastic shell 4 there is a flange 5 placed in the bore 6 formed on the outer surface of the expanding sleeve 3. The inner surface of the sleeve 3 is a conical cavity in which A spring 7 and a rod 8 are attached. A container 1 is acylated by a lid 9, on which a locking mechanism is fixed with screws 10 in the casing 11. The casing 11 protects the expanding sleeve 3 with the elastic casing 4 from the effects of the pressure forces of the material contained in the hopper. In the groove 12 formed in the lower part of the cavity of the casing 11, an elastic sealing ring 13 is installed, covering simultaneously the expanding sleeve 3 and the elastic casing 4, which is designed to prevent the bulk material from entering the cavity of the casing 11. For loading the bulk material, there are provided apertures 14 The stroke of the rod 8 is adjusted by the nut 15, and the force of the spring 7 is compressed by the sleeve 16. The bunker is equipped with a vibrator 17 located in the opening of the bracket 18, on which is fixed by means of spring-loaded bolts 19 e bottom 2 of the container 1 of the hopper. Under the discharge annular gap formed by the edge of the conical bottom 2 and the outer surface of the elastic sheath 4, it establishes with reinforcing part 20, with a gap concentrically centered in the center tube 21. The hopper operates as follows At the loading position, an actuator (not shown) moves the rod 8 upwards, compressing the spring 7. In this case, the contacting surfaces of the stem 8 and the expanding sleeve 3 come out of the engagement, and the expansion sleeve 3 is compressed, opening the annular gap in the discharge opening of the hopper From which the bulk material is dispensed from the container 1. The elastic sealing ring 13 expands, continuing to interact with its inner surface with the outer surface of the sleeve 3 and the Salt 4, preventing the bulk material from entering the cavity of the housing 11. After the material is dispensed, the actuator returns to its original position . The rod 8 under the action of the elastic force of the compressed spring 7 moves down. When the contacting surfaces of the expanding sleeve 3 and the rod 8 interact, the sleeve 3 expands and the outer surface of the elastic shell 4 hermetically closes the discharge ring gap. The vibrator 17 is turned on at the time of the dispensing of the material and serves to prevent the coalescence in the hopper and the flowability of the bulk material. The presence in the bunker of an elastic sealing ring, which encompasses both the expansion sleeve and the elastic shell, makes it possible to prevent loose material from entering the internal cavity of the casing, as a result of which the reliability of the bunker is improved. Claims Bin for storing and discharging bulk materials, according to ed.
