Description

Steam heating type oven Technical Field The utility model relates to the technical field of drying equipment, in particular to a steam heating type oven. Background In industrial production and laboratory applications, it is often necessary to heat and dry various materials. The existing steam heating type oven is used as drying equipment using steam as a heat source, and has a plurality of unreasonable parts in terms of structural layout. On one hand, the existing oven is poor in circulating air duct design, and the trend and shape of the air duct are not optimized, so that the circulation of hot air in the oven is uneven. The hot air flow in partial areas is not smooth, so that the materials are heated unevenly, the drying and heating effects are affected, and the production efficiency and the product quality are reduced. For example, in some ovens, hot air tends to form eddies in localized areas, while other areas are under-supplied with hot air. On the other hand, the position setting of circulating fan is unreasonable, can not give full play to its effect that drives the wind regime circulation for the wind regime can not fully heat transfer when the steam heater, and can not effectively spread after getting into the oven inner chamber, causes the energy waste. In order to solve the problem of unreasonable structural layout in the prior art, the utility model provides the steam heating type oven with more scientific and reasonable structural layout, so as to realize the purposes of high-efficiency and uniform heating of materials and the like. Disclosure of utility model Aiming at the defects in the prior art, the utility model provides the steam heating type oven, and solves the problems of uneven material heating, low equipment operation efficiency, inconvenient installation and maintenance and the like by optimizing the structural layout. In order to achieve the above purpose, the utility model adopts the following technical scheme: The steam heating type oven comprises an insulation box body, a circulating air duct, a steam heater, a circulating fan, a heat exhausting fan, a temperature sensor, a steam pipeline, a steam proportion adjusting valve, a control ball valve and a drain valve, wherein the insulation box body is formed into an oven main body and has good insulation performance, the circulating air duct is arranged in the insulation box body and surrounds the inner chamber of the oven, the steam heater is arranged in the circulating air duct, the circulating fan is arranged on the circulating air duct and is used for driving a wind source to circulate, the heat exhausting fan is arranged on the insulation box body, the temperature sensor is arranged at different positions of the inner chamber of the oven, the steam pipeline is connected with the steam source and the steam heater, and the steam proportion adjusting valve, the control ball valve and the drain valve are arranged on the steam pipeline. The oven further preferably further comprises an inner anti-collision strip and a temperature control box, wherein the inner anti-collision strip is arranged around the inner wall of the inner chamber of the oven, and the temperature control box is arranged on the outer side face of the heat insulation box body.
