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, 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 to be got back in heating cabinet and by the new wind Hybrid Heating entered in heating cabinet of valve, then send into baking oven casing by pressure fan, realize hot air circulation and use.But in the course of the work, if base material is coated with inflammable and explosive organic solvent, after base material enters baking oven heating, organic solvent evaporation is also full of baking oven casing to circulation baking oven.Base material due to baking oven tank ends is imported and exported and is left slit, if pressure is just in baking oven casing, then organic solvent gas can be overflowed by substrate slit.The organic solvent gas overflowed not only threatens operator safety, also may cause security incident.
Utility model content
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of heated-air circulation oven, thus makes it in process of production, and the gas in casing can not be excessive, and ensure dependability, security is good.
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 and the first valve, described heating cabinet installs new air valve by pipeline, described return air duct also connects air exhauster, the air draft pipe of described air exhauster is provided with the second valve; Setting pressure transmitter on described baking oven casing, described pressure transmitter to be connected PLC and frequency converter successively by circuit, and described frequency converter is connected with air exhauster.
The beneficial effects of the utility model are as follows:
The utility model is compact, reasonable, and manufacture and installation is convenient, and by the application of baking oven tank pressure transmitter and the adjustment of PLC, realize the tiny structure of baking oven box house, the gas finally realized in baking oven casing is not excessive.Greatly improve dependability and security.
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, pressure transmitter; 9, PLC; 10, frequency converter.
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 and the first valve 6, heating cabinet 1 installs new air valve 5 by pipeline, return air duct also connects air exhauster 4, the air draft pipe of air exhauster 4 is provided with the second valve 7; Setting pressure transmitter 8 on baking oven casing 3, pressure transmitter 8 to be connected PLC 9 and frequency converter 10 successively by circuit, and frequency converter 10 is connected with air exhauster 4.
In actual use procedure, the pressure set in PLC 9 in baking oven casing 3 is negative pressure, setting pressure transmitter 8 on baking oven casing 3, in order to measure the actual pressure of baking oven casing 3 inside, and negative pressure parameter set in transferring data to PLC 9 and PLC 9 is compared, PLC 9 according to correction data adjustment frequency converter 10, to change the rotating speed of air exhauster 4, realize the adjustment of exhausting air quantity, finally realize the tiny structure of baking oven casing 3 inside.
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.
