Description
Technical field
The utility model relates to baking oven technical field, especially a kind of heated-air circulation oven.
Background technology
Existing heated-air circulation oven, heating cabinet and circulating fan is connected at the external series of heating cabinet, and air exhauster is connected on heating cabinet, gas is heated to operating temperature by heating cabinet, hot gas in heating cabinet is sent in baking oven casing by circulating fan, and after hot blast completes the impingement drying to base material, a part of hot gas in baking oven casing is discharged by air exhauster, part hot gas enters in heating cabinet by the new wind of valve, realizes hot air circulation and uses.Recycling of hot blast can be completed.But circulation baking oven in the course of the work, if baking oven casing needs maintenance in short-term, just needs complete machine to shut down, again starts shooting after having overhauled again.Baking oven, from start to normal work, needs gas to be heated to operating temperature from normal temperature, and this needs the longer time, greatly have impact on operating efficiency.
Utility model content
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of heated-air circulation oven rational in infrastructure, thus makes it when baking oven casing overhauls in short-term, and the baking oven that can resume production fast, enhances productivity.
The technical scheme that the utility model adopts is as follows:
A kind of heated-air circulation oven, comprise baking oven casing, the described air supply duct of baking oven casing is connected with one end of heating cabinet, the described return air duct of baking oven casing is connected with the other end of heating cabinet, described air supply duct is provided with circulating fan, described return air duct installs new air valve by pipeline, described baking oven casing is also connected with on air supply duct that air exhauster is positioned at baking oven casing entrance end and the first valve is installed, the return air duct being positioned at baking oven casing entrance end installs the second valve, between described air supply duct and return air duct, connecting pipe is installed, described connecting pipe installs the 3rd valve.
The beneficial effects of the utility model are as follows:
The utility model is compact, reasonable, pipeline adds valve, during use, by the opening and closing of air-valve on pipeline, realize the switching of two kinds of hot air circulation in system, return to normal production fast after finally realizing the maintenance of baking oven casing, substantially increase production efficiency, use flexibility and reliability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, heating cabinet; 2, circulating fan; 3, baking oven casing; 4, air exhauster; 5, new air valve; 6, the first valve; 7, the second valve; 8, the 3rd valve; 9, connecting pipe.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As shown in Figure 1, the heated-air circulation oven of the present embodiment, comprise baking oven casing 3, the air supply duct of baking oven casing 3 is connected with one end of heating cabinet 1, the return air duct of baking oven casing 3 is connected with the other end of heating cabinet 1, air supply duct is provided with circulating fan 2, return air duct installs new air valve 5 by pipeline, baking oven casing 3 is also connected with on air supply duct that air exhauster 4 is positioned at baking oven casing 3 entrance end and the first valve 6 is installed, the return air duct being positioned at baking oven casing 3 entrance end installs the second valve 7, connecting pipe 9 is installed between air supply duct and return air duct, connecting pipe 9 installs the 3rd valve 8.
The utility model have employed increases by first valve 6 on air supply duct, and return air duct increases by second valve 7, between air supply duct and return air duct, increase by one section of connecting pipe 9, and increases the 3rd valve 8 on this pipeline.When baking oven casing 3 overhauls in short-term, open the 3rd valve 8 between air supply duct and return air duct, close the first valve 6 on air supply duct, close the second valve 7 on return air duct, reach and realize new hot air circulation.Hot-air remaining in baking oven casing 3 extracted out by air exhauster 4, and baking oven casing 3 overhauls after cooling.After having overhauled, open the second valve 7 on return air duct, open the first valve 6 on air supply duct, close the 3rd valve 8 between air supply duct and return air duct, then the hot blast now with higher temperature enters baking oven casing 3.
More than describing is to explanation of the present utility model, and be not the restriction to utility model, the utility model limited range, see claim, within protection domain of the present utility model, can do any type of amendment.
