Abstract
The utility model relates to a radiation type hot wind circulation drying device, comprising a chamber body 1, a circulation motor 2, a hot wind furnace 4, characterized in that: a radiation plate 11 and hot wind pipes 10 are arranged in the inner cavity of the chamber body 1, the inner cavity of the chamber body 1 is separated into a drying chamber 7 and a hot wind channel 8 by the radiation plate, the hot wind channel 8 is in a square-hole full-closed cavity; the hot wind pipes are arranged at the inner side of the radiation plate and two ends of the hot wind pipes are communicated with the hot wind channel 8. The advantages of the radiation type hot wind circulation drying device are that: the heated circulation hot wind is completely separated from the workpiece 9 to be heated, the dust particle in the circulation wind can not be adhered on the surface of the workpiece 9 and the quality of the paint on the surface of the workpiece 9 is increased. The radiation plate 11 and the hot wind pipes 10 simultaneously radiate and exchange the heat, so as to increase the heat radiation area and has high heat exchange rate. During the drying process, the waste gas can be recycled, thus the energy can be saved and the environment can be protected.
Description
Technical field
The utility model relates to the drying unit in the paint line, particularly a kind of radiant type hot air circulation drying unit.
Background technology
Every profession and trade all need to product surface carry out anticorrosion, decorate, be coated with protective finish, as be coated with in cataphoretic priming, primer spray, the spray, topcoating etc., processing need be dried in the surface after its spraying.At present, owing to adopt traditional hot air circulation oven dry, the hot-air after the heating directly gets into drying chamber to drying unit after filtering mostly, and processing is dried on the surface behind the workpiece paint.This direct drying mode, the dust particle in its circulating air adheres to or pollutes the paint of surface of the work easily, and the surface of the work paint quality is descended.
Summary of the invention
The utility model technical barrier to be solved is to overcome above-mentioned surface of the work and be prone to by the deficiency of air dust particle pollution a kind of radiant type hot air circulation drying unit is provided.
The technical solution of the utility model is; Comprise chamber body 1, circulating fan 2, hot-blast stove 4; Be provided with the ajutage 3 and backwind tube 5 that communicate with it between the furnace chamber of the inner chamber of chamber body 1 and hot-blast stove 4; It is characterized in that: be provided with warm-air pipe 10 and radiant panel 11 in the inner chamber of chamber body 1, radiant panel 11 is separated into drying chamber 7 and 8 two cavitys of hot-air channel with the inner chamber of chamber body 1, and hot-air channel 8 is the totally-enclosed cavity of " returning " font; Warm-air pipe 10 is arranged in the drying chamber 7 of radiant panel 11 inboards, and the two ends of warm-air pipe 10 communicate with hot-air channel 8 and constitute the hot air circulation loop.
Also be provided with exhaust gas recycling tube 6 between the hot-air channel 8 of chamber body 1 inner chamber and the furnace chamber of hot-blast stove 4.
Said radiant panel 11 is imitated radiative material for the aluminising plate hight and is made.
The advantage that the utility model is compared with prior art possessed, the one, radiant panel 11 is assisted and is added warm-air pipe 10 dual stacks as heat radiation part, has increased heat radiation surface greatly, has improved radiation efficiency; The 2nd, hot-air and drying chamber 7 in airtight " returning " font circulating air passage 8 separate fully, make the dust in air particle can not adhere on the paint on workpiece 9 surfaces, thereby have improved the paint quality on workpiece 9 surfaces; The waste gas that produces during oven dry causes burning once more in the hot-blast stove 4 through exhaust gas recycling tube road 6, and heat energy is fully used.Therefore, the utlity model has the characteristics of high efficiency, energy-saving and environmental protection, cleaning.

The specific embodiment
The utility model comprises chamber body 1, circulating fan 2, hot-blast stove 4, is provided with ajutage 3, backwind tube 5 and the exhaust gas recycling tube 6 that communicates with it between the furnace chamber of the inner chamber of chamber body 1 and hot-blast stove 4.
Be provided with radiant panel 11 and warm-air pipe 10 in the inner chamber of chamber body 1, radiant panel 11 is separated into drying chamber 7 and 8 two cavitys of hot-air channel with the inner chamber of chamber body 1, and hot-air channel 8 is " returning " font, is the totally enclosed type cavity; Warm-air pipe 10 is arranged in the drying chamber 7 of radiant panel 11 inboards, and the two ends of its warm-air pipe 10 communicate with hot-air channel 8, and also promptly, hot-air channel 8 constitutes the hot air circulation loop of sealing with warm-air pipe 10.
Also be provided with the exhaust gas recycling tube 6 that can heat-exchanged air be carried out recycling between the furnace chamber of the inner chamber of chamber body 1 and hot-blast stove 4.
Filling rock wool heat-preservation material formed in the middle of chamber body 1 adopted double-layer plate.Said radiant panel 11 is imitated radiative material for the aluminising plate hight and is made, and warm-air pipe 10 forms for the higher steel pipe manufacturing of heat conductivility.Radiant panel is the totally-enclosed structure, and circulated air is not contacted with heated parts.
The bottom of chamber body 1 inner chamber hot-air channel 8 communicates with hot-blast stove through ajutage 3 and backwind tube 5.Send into the hot-air in the hot-air channel 8; Through radiant panel 11, heat energy is carried out radiation exchange on the one hand, surface of the work paint in the drying chamber is carried out radiative oven dry; On the other hand; Pipe surface through warm-air pipe 10 carries out heat exchange in drying chamber 7, to increase heat radiation area, dual raising paint drying effect.By backwind tube 5, under the graviational interaction of circulating fan 2, the circulation heating realizes the continuous drying to workpiece in hot-blast stove 4 through heat-exchanged air.
The utility model, the heat cycles hot-air be heated workpiece 9 and separate fully, the dust particle in the circulated air can't adhere on workpiece 9 surfaces, has improved the paint quality on workpiece 9 surfaces.The waste gas that produces during oven dry causes burning in the hot-blast stove 4 through exhaust gas recycling tube 6, and waste gas is qualified discharge after burning.Radiant panel 11 auxilliary warm-air pipe 10 radiation heat transfers simultaneously that add have increased the heat radiation area, and rate of heat exchange is high.The heat that burnt gas produces, after the heat exchanger heat exchange, circulation heated parts 9, heat energy is fully utilized.Therefore, the utlity model has the characteristics of high efficiency, energy-saving and environmental protection, cleaning.
