Description

Изобретение относится к устройствам для сушки обуви и предназначено для· использования на предприятиях лег кой промышленности, а также на фабриках и в мастерских по ремонту и пошиву обуви сферы бытового обслуживания населения.The invention relates to devices for drying shoes and is intended for use in light industry enterprises, as well as in factories and in workshops for repairing and sewing footwear in the sphere of consumer services.

Известно устройство для сушки изделий, например деталей обуви, содержащее сушильную камеру с загрузочным окном, транспортер, .вентиляционную систему и нагреватели [1].A device is known for drying products, for example shoe parts, comprising a drying chamber with a loading window, a conveyor, a ventilation system, and heaters [1].

Недостатком этого устройства является сравнительно низкий коэффициент теплоотдачи нагревателей воздушному потоку, в результате чего температура по объему камеры неравномерная‘и как следствие качество сушки не отвечает предъявляемым требованиям.The disadvantage of this device is the relatively low heat transfer coefficient of the heaters to the air flow, as a result of which the temperature throughout the chamber volume is uneven, and as a result, the drying quality does not meet the requirements.

Цель изобретения - повышение качества сушки за счет равномерного нагрева и распределения сушильного агента по всему объему сушильной камеры .The purpose of the invention is improving the quality of drying due to the uniform heating and distribution of the drying agent throughout the volume of the drying chamber.

Поставленная цель достигается тем, что сушильная камера выполнена в виде ванны и имеет воздухораспределительную решетку, расположенную под фильтром, электронагреватели, помещенные в слой зернистой насадки и установленные на решетке, и окна для всасывания воздуха, расположенные под решеткой, а боковые стенки ван_ ны выполнены полыми и имеют каждая ³ .перегородку, при этом одна часть стенки соединена посредством жалюз с окружающей средой, а другая с подрешеточным пространством ванны через всасывающие окна.This goal is achieved by the fact that the drying chamber is made in the form of a bathtub and has an air distribution grill located under the filter, electric heaters placed in the granular nozzle layer and installed on the grill, and windows for air intake located under the grill, and the side walls of the bathtub are hollow and each one has a ^3. partition, while one part of the wall is connected by means of a louvre to the environment, and the other to the sublattice space of the bathtub through suction windows.

Устройство для сушки обуви содер15 жит корпус 1, состоящий из стенок: наружной 2 и внутренней 3, -стенки . образуют каналы: наружный 4, соединенный с окружающей средой посредством жалюз^; 5, а внутренний канал 6 20 соединен с наружным каналом перепускным окном 7. Внутренний канал окончен всасывающим окном 8 и разделен с наружным каналом перегородкой 9. Внутри сушильной камеры 10 размеще25 ны защитный экран 11, транспортер 12, термопара 13, фильтр 14, теплообменник 15 с установленными электронагревателями 16, с электррконтактами 17, находящимися под слоем зернистой 30 насадки 18, воздухораспределительная решетка 19, подрешеточное пространство 20, загрузочное окно 21 с дверкой 22, вентиляционная система 23.The device for drying shoes contains a housing 1, consisting of the walls: outer 2 and inner 3, wall. form channels: outer 4, connected to the environment through a blind ^; 5, and the inner channel 6 20 is connected to the outer channel by the bypass window 7. The inner channel is terminated by the suction window 8 and is divided by the partition 9 with the outer channel. Inside the drying chamber 10, a protective screen 11, a conveyor 12, a thermocouple 13, a filter 14, a heat exchanger 15 are placed with installed electric heaters 16, with electrical contacts 17 located under a layer of granular 30 of nozzle 18, air distribution grill 19, sublattice space 20, loading window 21 with door 22, ventilation system 23.

Предлагаемое устройство работает следующим образом.The proposed device operates as follows.

Через электроконтакты 17 электроэнергия поступает на электронагреватель 16. Электронагреватели нагреваются и нагревают слой зернистой насадки 18. При достижении температуры слоем зернистой насадки до заданных технологическим процессом величин открывают дверку 22 и через загрузочное окно 21 загружают обувь для сушки на транспортер 12. После этого закрывают дверку.загрузочного окна и включают вентиляционную систему 23₍которая создает некоторое разрежение в сушильной камере 10. Засасывав·' ьий воздух, служащий сушильным агентом, проходит через жалюзи 5, наружный канал 4, перепускное окно 7, внутренний канал 6, всасывающие окна 8, подрешеточное пространство 20, воздухораспределительную решетку 19 и попадает в теплообменник 15, где нагревается до заданной температуры. Пройдя фильтр 14 и защитный экран 11, сушильный агент поступает в камеру для сушки обуви, размещенной на транспортере, и одновременно обогревает внутреннюю сменку 3 корпуса 1. При этом происходит сушка обуви. После выдержки, предусмотренной технологическим процессом, вентиляционную систему выключают и открывают дверку загрузочного окна. Обработанную обувь удаляют из сушильной камеры и загружают новую партию. Таким образом цикл повторяется. Следует отметить, что засасываемый воздух при проходе через наружный канал охлаждает наруж ную стенку корпуса и служит как теплоизоляция, и затем при проходе через внутренний канал нагревается от температуры внутренней стенки корпуса. Контроль и регулировку температуры внутри сушильной камеры производят 1 при помощи термопары 13 и электрической схеьы.Through electrical contacts 17, electricity is supplied to electric heater 16. Electric heaters heat up and heat the layer of granular nozzle 18. When the temperature reaches the layer of granular nozzle to the values specified by the technological process, open door 22 and load shoes for drying onto conveyor 12 through boot window 21. After that, close the door. loading gate and include a ventilation system 23 _(which creates a vacuum in the drying chamber 10. The sucked · 'y air serving as a drying agent, passes Jun through the blinds 5, the outer channel 4, the bypass window 7, the inner channel 6, the suction windows 8, the sublattice space 20, the air distribution grill 19 and enters the heat exchanger 15, where it is heated to a predetermined temperature. After passing through the filter 14 and the protective screen 11, the drying agent into the chamber for drying shoes placed on the conveyor, and at the same time heats the inner shift 3 of case 1. Drying of the shoes takes place.After the shutter speed provided by the technological process, the ventilation system is turned off and the door closes tipping window. Treated shoes are removed from the drying chamber and a new batch is loaded. Thus the cycle repeats. It should be noted that the sucked air when passing through the outer channel cools the outer wall of the housing and serves as thermal insulation, and then, when passing through the inner channel, it heats up from the temperature of the inner wall of the housing. Temperature control and adjustment inside the drying chamber is carried out 1 using a thermocouple 13 and an electric circuit.

Используя слой зернистой насадки, нагреваемой электронагревателями, можно получить равномерный нагрев · сушильного агента по всему объему сушильной камеры и как результат улучшается качество сушки обуви.Using a layer of a granular nozzle heated by electric heaters, it is possible to obtain uniform heating of the drying agent throughout the entire volume of the drying chamber and, as a result, the drying quality of shoes is improved.
