Изобретение относитс к сушильным устройствам и может быть применено дл сушки лакокрасочных покрытий.The invention relates to drying devices and can be applied for drying paint coatings.

Известна сушильна камера, содер жаща корпус, с размещенным в нем центробежным вентил тором, .соединенным с отсасывающей и нагнетательной ветв ми рециркул ционного канала, и газораспределительный короб дл подачи сушильного агента внутрь камеры 1 .A known drying chamber containing a casing, with a centrifugal fan placed in it, connected to the suction and discharge branches of the recirculation channel, and a gas distribution box for feeding the drying agent inside the chamber 1.

Недостатком известной камеры- вл етс недостаточна эффективность сушки лакокрасочных покрытий при непрерывном движении высушиваемых изделий вдоль камеры.A disadvantage of the known chamber is the insufficient effectiveness of drying paint coatings with the continuous movement of dried products along the chamber.

Целью изобретени вл етс интенсификаци процесса сушки.The aim of the invention is to intensify the drying process.

Указанна цель достигаетс тем, что корпус выполнен с двойными стенками , и камера дополнительно содержит второй рециркул ционный канал, с установленнь1м на нем автономным вентил тором, вынесенным за пределы корпуса и подключенным к объему камеры и отсасывающей ветви первого рециркул ционного канала, причем нагнетательна ветвь последнего расположена с обеих сторон корпуса иThis goal is achieved by the fact that the casing is made with double walls, and the chamber further comprises a second recirculation channel, with an autonomous fan installed on it, placed outside the casing limits and connected to the chamber volume and the suction branch of the first recirculation channel. located on both sides of the case and

соединена с газораспределительным коробом, и через межстёночное пространство с отсасывающей ветвью этого канала.it is connected to the gas distribution duct, and through the inter-wall space to the suction branch of this channel.

На фиг. 1 изображена сушильна . камера, продольный разрез; на фиг. 2 - сечение по А-А на фиг. 1°, на фиг. 3 - сечение по Б-Б на фиг. I на фиг. 4 - изображение сушильной камеры в аксонометрии.FIG. 1 depicts a dryer. camera, longitudinal section; in fig. 2 is a section along A-A in FIG. 1 °, in FIG. 3 is a section along BB in FIG. I in FIG. 4 is a perspective view of the drying chamber.

Сушильна камера состоит из корпуса 1 с наружной стенкой 2 и внутренней 3, центробежного вентил тора 4, установленного на валу 5 и соединенного через клиноременную передачу 6 с электродвигателем 7, который закрыт кожухом 8. Центробежный вентил тор 4 соединен с нагнетательной ветвью 9, расположенной с обеих сторон корпуса 1 и соединенной с. газоподвод щим коробом 10 дл ввода сушильного агента внутрь корпуса. 1 и с отсасывающей ветвью 11.The drying chamber consists of a housing 1 with an outer wall 2 and an internal 3, a centrifugal fan 4 mounted on the shaft 5 and connected via a V-belt transmission 6 to an electric motor 7, which is closed by a casing 8. The centrifugal fan 4 is connected to a discharge branch 9 located with both sides of housing 1 and connected with. a gas supply duct 10 for introducing the drying agent into the body. 1 and with a suction branch 11.

Claims

The discharge branch 9 in the upper part is divided into longitudinal channels 12, which serve to distribute the recirculating drying agent along the chamber. In the upper part of the chamber, suction pipes 13 3 are connected via pipe 14 to an independent fan 15, which is connected by pipe 16 to the suction branch 11. Suspensions 17 are placed between pipes 13 to move their products along the corps 1 to regulate the temperature of the circulating mixture of drying The agent has a thermal effect controller 18 installed. The camera is operated as follows. The drying agent by the centrifugal fan 4 through the pressure branch 9 enters the interwall space formed by walls 2 and 3, from where it goes to the suction branch 11. When the drying agent moves along the closed loop, the mechanical energy of the fan 4 passes to. warmth The inner wall 3 is heated and becomes radiating from a heat radiator, i.e. serves as a thermo-radiation panel. At the same time, a part of the drying agent through the gas distribution duct 10 is fed into the housing 1 and is sucked through the nozzle 13 by an autonomous fan 15 into the suction branch 11. A part of the exhausted air is emitted by the fan 15 into the atmosphere in order to reduce the solvent vapor concentrations. The continuously transportable dried product on the suspension 17, passing between the inner walls 3, is dried both from the effects of thermal radiation from the walls 3 and by convection, when the product is washed with a directed stream of drying agent. This ensures fast and high-quality drying. Claims of the Invention Drying chamber, preferably for drying paint coatings, comprising a housing with a centrifugal fan placed therein, connected to the suction and discharge branches of the recirculation channel, and the gas distribution duct for supplying the drying agent to the inside of the chamber, characterized in that the purpose of intensification of the drying process, the casing is made with double walls, and the chamber additionally contains a second recirculation channel, with an autonomous fan installed on it, placed outside of the casing and connected to the chamber volume and the suction branch of the first recirculation channel, the discharge branch of the latter located on both sides of the casing and connected to the gas distribution duct and through the inter-wall space to the suction branch of this channel.
