Изобретение относитс к технике сушки и может быть использовано в химической, иищевой , птицеперерабатывающей и других отрасл х промышленности, например дл сушки перо-пухового сырь .The invention relates to a drying technique and can be used in the chemical, iischevoy, poultry processing and other sectors of the industry, for example for drying feather-down raw materials.

Наиболее близкой к изобретению по технической сущности и достигаемому результату вл етс установка дл сушки рыхлых материалов , содержаща камеру с перфорированным ленточным транспортером, между ветв ми которого размещен газоподвод щий коллектор . Высушиваемый материал перемещаетс вдоль камеры на ленточном транспортере и продуваетс снизу вверх теплоносителем , поступающим через перфорацию в ленте из газоподвод щего коллектора.Closest to the invention in its technical essence and the achieved result is a plant for drying loose materials, comprising a chamber with a perforated belt conveyor, between which branches there is a gas supplying collector. The material being dried is moved along the chamber on a belt conveyor and is blown from the bottom up by a heat carrier flowing through the perforations in the belt from the gas supplying collector.

Недостатками такой установки вл ютс неравномерность обработки материала и низка надежность в эксплуатации.The disadvantages of this setup are uneven processing of the material and low reliability in operation.

Целью изобретени вл етс повышение эксплуатационной надежности и качества сушки.The aim of the invention is to increase the operational reliability and quality of drying.

Поставленна цель достигаетс тем, что в предлагаемой установке перфораци на транспортере выполнена в виде секций, кажда из которых состоит по крайней мере из двух поперечно расположенных р дов, и над транспортером размещена сетка, служаща дл поддержани материала. Кроме того, в каждой секции перфораци размещена с шагом.This goal is achieved by the fact that in the proposed installation the perforations on the conveyor are made in the form of sections, each of which consists of at least two transversely arranged rows, and a grid is placed above the conveyor to support the material. In addition, perforations are placed in each section in increments.

равным двум периметрам одного отверсти , а рассто ние между секци ми составл ет 6,25-12,5 этого же иериметра. Дополнительно над перфорацией одной из секций укреплены иоворотные козырьки, наклонные в сторону , противоположную направлению движени транспортера.equal to two perimeters of one hole, and the distance between the sections is 6.25-12.5 of the same ierimeter. Additionally, over-perforations of one of the sections are reinforced with rotation caps, inclined in the direction opposite to the direction of movement of the conveyor.

Установка содержит камеру 1, газораспределительную сетку 2, загрузочное 3 и разгрузочное 4 устройства, ворошитель 5, газоподвод щий короб 6, газоподвод щий коллектор 7, газоотвод щий патрубок 8, перегородки 9, ленточный транспортер 10 с козырьками 11 иThe installation comprises a chamber 1, a gas distribution grid 2, a loading 3 and a discharge 4 devices, a agitator 5, a gas supply duct 6, a gas supplying manifold 7, a gas outlet 8, partitions 9, a belt conveyor 10 with peaks 11 and

перфорацией, выполненной в виде секций 12, ведущий 13 и ведомый 14 барабаны с ребордами 15, устройство 16 дл нат жени ленты, привод 17. Газоподвод щий коллектор 7 имеет на обращеииой вверх поверхности окна 18 дл подачи теплоносител под верхнюю ветвь транспортера 10.perforation, made in the form of sections 12, the leading 13 and the driven 14 drums with flanges 15, the belt tensioning device 16, the drive 17. The gas supply manifold 7 has upwardly the surface of the window 18 for supplying coolant under the upper branch of the conveyor 10.

Claims

The perforation of section 12 consists of several transversely arranged rows; over the openings 19 of one of the sections 12, the caps 11 are located. The perforations in the sections 12 are placed in a step equal to two perimeters of one opening 1-9, and the distance between the sections 12 is 6.25-12.5 of the same perimeter. The installation works as follows. The material to be sourced, for example, downy raw materials, is fed into the chamber 1 on the grid 2 by the charging device 3. The material is preliminarily crushed using the agitator 5. From the gas supplying collector 7, coolant flows through the windows 18 under the upper branch of the belt conveyor 10 in the gas supply duct 6. Through the net 2, the coolant is introduced in separate streams from the openings 19 in the conveyor belt 10. Due to the arrangement of the sections 12, the material is pulsed. The frequency of the pulses is also determined by the speed of movement of the conveyor 10. The movement of the material along the grid 2 is facilitated by the flow of coolant at an angle to it, which is provided by the visors 11 inclined in the direction opposite to the direction of movement of the conveyor 10. The dried material and the spent coolant with small fractions through the nozzle 8. The conveyor belt 10 is moved by means of an actuator 17 connected to the driving drum 13, and its tension is produced oschi device 16 disposed at the driven drum 14. The drums 13 and 14 have flanges 15 which serve as guides for the conveyor belt 10. Partitions 9 having a slit for the passage of the conveyor belt 10, serves to protect an drums 13 and 14 by heating. The design of the proposed installation allows to provide, depending on the properties of the material being dried, different qualitative character of its movement in chamber 1: transport by dunes, loosened flow, etc. The installation is simple and reliable in operation, its performance is regulated in a wide range. Intensive mixing of the material improves the quality of drying. Claims 1. Apparatus for drying loose matins, mainly feather-down raw materials. comprising a chamber with a perforated belt conveyor, between which branches a gas supplying collector is placed, characterized in that, in order to increase the operational reliability and quality of drying, the perforations on the conveyor are made in the form of sections, each of which consists of at least two transversely arranged rows, and a mesh is placed above the conveyor to support the material. -

2. Installation according to claim 1, characterized in that the perforations in each section are arranged with shtam equal to two perimeters of one hole, and the distance between the sections is 6,, 5 of the same perimeter.

3. Installation according to claim I, characterized in that, over the perforation of one of the sections, swiveling canopies are tilted, inclined in the direction opposite to the direction of movement of the conveyor.
