Abstract
A printing drying oven is formed by connecting a support, an air heater, an air inlet, an oven body and an air outlet through pipelines in sequence. The air heater and the oven body are both mounted on the support and are connected through an air inlet pipe, the air inlet is formed in the top of the air heater, a heat exchange device is arranged in the air inlet, an air inlet chamber, an upper exhaust chamber, a lower exhaust chamber and a drying chamber are formed in the oven body, a lower exhaust pipe is arranged on one side of the lower exhaust chamber, a circulating pipe is arranged on the top of the upper exhaust chamber, and the circulating pipe is respectively communicated with the heat exchange device and the air heater. The printing drying oven solves the technical problem that the utilization rate of secondary circulating hot air of a traditional printing drying oven is low, the upper exhaust chamber can obtain exhaust gas with low solvent convent by adopting the structure that the upper exhaust chamber and the lower exhaust chamber are separated, the exhaust gas is recycled through the circulating pipe, and the utilization rate of the secondary circulating hot air is improved greatly.
Description
Technical field
The utility model relates to heat treatment and apparatus field, relates to printing industry, especially a kind of printing drying oven.
Background technology
The key parameter such as drying oven inside configuration hot blast temperature, air quantity and blast that is exclusively used in printing directly affects print quality, and the solvent residual amount that oven drying produces simultaneously also can exert an influence to the quality of printing product; Therefore, optimize oven structure, guarantee that the uniformity of oven interior wind speed, temperature, pressure and controllability are the major criterions of design baking oven, have important meaning to improving print quality, guarantee production safety and saving the energy.
Traditional drying oven adopts more connects one section of backwind tube in exhaust duct, and a part of hot blast is carried out to secondary cycle, can only circulate 20%～30% hot blast rate of this circulation way, and air circulation is lower; And contain considerable residual solvent in the hot blast of secondary cycle, such hot blast passes into admission line and carries out secondary while utilizing, can cause the residual solvent amount of oven interior to raise, exceed LEL value, bring potential safety hazard to production; And it is minimum that this method is difficult to make the residual solvent amount in printed matter to drop to, and can not better guarantee print quality, is also unfavorable for energy-conservation.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of and guarantee safety in production in improving secondary cycle hot blast utilization rate, improves the one printing drying oven of print quality.
The purpose of this utility model is achieved through the following technical solutions:
A kind of printing drying oven, by support, air-heater, air inlet, baking oven, exhaust outlet connects to form successively by pipeline, described air-heater is all installed on support and by blast pipe and is connected with baking oven, described air-heater top is shaped with air inlet, this air inlet place is provided with heat-exchange device, in described baking oven, be provided with inlet plenum, upper exhaust chamber, lower exhaust chamber and drying chamber, described inlet plenum is connected with blast pipe, this inlet plenum is connected with drying chamber by multiple nozzles of uniform setting, described drying chamber one side is provided with multiple backwind tubes and upper, lower exhaust chamber is connected, described lower exhaust chamber one side is provided with lower exhaust duct, upper exhaust chamber top is provided with circulation pipe, and this circulation pipe is connected with heat-exchange device and air-heater respectively.
And described heat-exchange device is efficient heat-pipe heat-exchanger, this heat exchange of heat pipe is coated on air inlet, and this heat exchange of heat pipe tail end is provided with exhaust outlet.
And described lower exhaust outlet is provided with valve A.
And described circulation pipe and heat-exchange device connectivity part are provided with valve B.
And described circulation pipe and air-heater connectivity part are provided with valve C.
Advantage of the present utility model and economic effect are:
1, the utility model has overcome the low technical barrier of traditional printing drying oven secondary cycle hot blast utilization rate, by the structure that adopts upper and lower exhaust chamber to separate, make exhaust chamber can obtain the waste gas of low solvent, by circulation pipe, waste gas is re-used, greatly improved the utilization rate of secondary cycle hot blast.
2, the heat-exchange device that the utility model arranges by air inlet, can be passed to the heat in waste gas in fresh air, reaches the effect of preheating, greatly reduces the working strength of air-heater, reaches energy-conservation effect; , because heat-exchange device is just passed to heat in fresh air, solvent is not introduced in air inlet meanwhile, can greatly be improved print quality.
3, the utility model, by the waste gas of low solvent is caused in air-heater by circulation pipe, has reduced the fresh air entering widely, thereby reduces the required heat energy of heating fresh air, reaches energy-conservation effect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model (broken section).
