Изобретение относитс к области подъ- : емно-транспортного машиностроени , а именно к ленточным конвейерам. The invention relates to the field of lifting and transport machinery, namely to belt conveyors.

Целью изобретени вл етс повышение долговечности работы путем- снижени потерь энергии при охлаждении и износа ленты.The aim of the invention is to increase the durability of the work by reducing the energy loss during cooling and tape wear.

На фиг. 1 изображен общий вид сек- : ции конвейера, вид сбоку; на фиг. 2 - раз- i реЗ А-А на фиг. 1; на фиг. 3 - узел I на фиг, 2; н фиг. 4 - узел И на фиг. 2.FIG. 1 shows a general view of the section: side of the conveyor; in fig. 2 - cut and cut A-A in FIG. one; in fig. 3 - node I in FIG. 2; n FIG. 4 - node And in FIG. 2

Секци ленточного конвейера состоит из установленного под лентой 1 на опоре 2 конвейера рабочего стола 3, выполненного в виде отдельных опорных полых элементов 4 и снабженного системой 5 дл подачи и отвода охлаждающего агента, и опорных стоек 6. Каждый полый элемент 4 снабжен полым корпусом 7, герметично присоединенным к рабочей стенке 8 так, что охлаждающа полость 9 расположена внутри него с зазором относитель- 20 но основани 10. Отвод агента выполнен в виде змеевика 11, расположенного между корпусом 7 и охлаждающей полостью 9. Система 5 дл подачи и отвода охлаждающего агента состоит из расположенных на опорных стойках 6 патрубков 12 и 13 - с закрепленными на них шлангами 14, соедин ющими с единой системой подвода и отвода охлаждающего агента конвейера. Опорные стойки 6 имеют канал 15, объедин ющий отводы опорных элементов с патрубком 12, и канал 16, соедин юпдий подводы элементов 17 с патрубком 13.The belt conveyor section consists of a desktop 3 installed under the belt 1 on the pole 2 of the conveyor, made in the form of separate supporting hollow elements 4 and provided with a system 5 for supplying and discharging a cooling agent, and supporting racks 6. Each hollow element 4 is provided with a hollow body 7, tightly attached to the working wall 8 so that the cooling cavity 9 is located inside it with a gap relative to the base 10. The withdrawal of the agent is made in the form of a coil 11 located between the housing 7 and the cooling cavity 9. The system 5 for cottages and discharge a cooling agent consists of a rack located on the support 6 nozzles 12 and 13 - with attached thereto the hoses 14 connecting the system with a single supply and discharge conveyor of the cooling agent. The support legs 6 have a channel 15, which connects the outlets of the supporting elements with the pipe 12, and the channel 16, connecting the connections of the elements 17 with the pipe 13.

Секци ленточного конвейера работает следующим образом.The belt section operates as follows.

Лента 1 с грузом движетс по опорнойTape 1 with a load moving on the reference

В результате охлаждени рабочей поверхности на ней конденсируетс влага из окружающего теплого воздуха, образу смазочный слой, величину которого можно регулировать степенью охлаждени рабочей поверхности. Дл повышени эффективности охлаждени и снижени потерь энергии охлаждени полость 9 герметично закрыта защитным 10 корпусом 7 с зазором между боковыми стенками и основанием 10.the binding agent through the coil 11, the supporting channels 15 and the nozzle 12. As a result of cooling the working surface, moisture from the surrounding warm air condenses on it, forming a lubricating layer, the size of which can be controlled by the degree of cooling of the working surface. To increase cooling efficiency and reduce cooling energy losses, cavity 9 is hermetically sealed with protective 10 housing 7 with a gap between the side walls and the base 10.
