[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0034] This utility model provides a curing device for a PVC high-foaming energy-saving oven, including an inner box 1;
[0035] The top of the inner box 1 is provided with an internal circulation mechanism 3 for energy saving through heat circulation, the outside of the inner box 1 is provided with an insulation component 2 for preventing heat leakage, the back of the inner box 1 is provided with an exhaust mechanism 5 for gas discharge, and the inside of the inner box 1 is provided with a heating mechanism 4 for heating and cooking.
[0036] The internal circulation mechanism 3 includes;
[0037] A drive assembly is located on the top of the inner box 1, and a transmission assembly is provided on one side of the drive assembly;
[0038] Heating mechanism 4 includes;
[0039] A support assembly is located inside the inner box 1, and a heating assembly is located on the outside of the support assembly.
[0040] Preferred;
[0041] like Figure 3 As shown, the driving component includes;
[0042] The outer cover 31 is fixedly installed on the top of the inner box 1. The first motor 32 and the first shaft 33 connected to the output shaft of the first motor 32 are fixedly installed at one end of the top of the outer cover 31.
[0043] The outer cover 31 can provide rotational support for the first shaft 33 and the second shaft 36, and can also support the first motor 32. The first motor 32 can complete the power output operation after starting. The first shaft 33 can ensure the transmission of rotational force and drive the first fan 35 to rotate.
[0044] A first gear 34 is fixedly installed on the outer side of the first shaft 33, and a first fan 35 is fixedly installed on the bottom end of the first shaft 33. During the rotation of the first fan 35, the gas below can be drawn outward and discharged to achieve an internal circulation effect.
[0045] further;
[0046] like Figure 3 As shown, the transmission assembly includes;
[0047] The second gear 37 meshes with one side of the first gear 34. The inner side wall of the second gear 37 is fixedly mounted with a second shaft 36 and a second fan 38 fixed to the bottom end of the second shaft 36. It can cooperate with the above to discharge to the outside, and the simultaneous operation of the two can increase the circulation efficiency and the uniformity of heat distribution during heating.
[0048] It is worth explaining;
[0049] like Figure 5 As shown, supporting components;
[0050] The partition frame 41 is fixedly installed on the inner wall of the inner box 1. The inner wall of the partition frame 41 has air holes 42, which serve to support the material and distribute the heat carried by the gas to the material inside.
[0051] Going a step further;
[0052] like Figure 5 As shown, heating components;
[0053] A baffle 43 is fixedly installed at the center of the top of the partition frame 41. Both ends of the top of the partition frame 41 are provided with perforations 44 and mesh plates 45 fixed to the inner sidewalls of the perforations 44. A heating tube 46 is fixedly installed on the outer side of the partition frame 41. The partition frame 41 can separate the space at its top, ensuring that the first fan 35 and the second fan 38 will not interfere with each other. The cooperation of the perforations 44 and the mesh plates 45 can ensure the circulation of gas and also play a role in blocking and protecting.
[0054] During operation, the first motor 32 runs and drives the first gear 34 and the first fan 35 to rotate synchronously through the first shaft 33. The first gear 34 meshes with the second gear 37 and drives the second shaft 36 and the second fan 38 to rotate synchronously, thereby realizing the internal circulation operation on both sides at the same time.
[0055] During internal circulation, the heating tube 46 is pre-activated for heating. The temperature is controlled to reach the preset value by the connected silicon controlled rectifier temperature controller. Then, the first fan 35 and the second fan 38 rotate to extract the gas below. When the extraction force is generated, the heat will be discharged from the air hole 42, and the gas on both sides below will be drawn upward until it passes through the material for heating and cooking. The extracted gas will enter the space between the partition frame 41 and the inner box 1. Continuous operation will blow the heat near the heating tube 46 through the air hole 42 and through the material, thereby repeatedly realizing the internal circulation operation. This improves the uniformity of heating, increases work efficiency, and maximizes the utilization of heat to achieve energy saving.
[0056] in;
[0057] like Figure 4 As shown, the thermal insulation component 2 includes;
[0058] Insulation cotton 21 is fixedly installed on the outside of the inner box 1. An outer box 22 is fixedly installed on the outside of the insulation cotton 21. The insulation cotton 21 achieves the insulation effect, and the outer box 22 can not only protect the internal structure, but also provide insulation and protection.
[0059] at last;
[0060] like Figure 4 As shown, the exhaust mechanism 5 includes;
[0061] The exhaust pipe 51 is connected to the back of the inner box 1. A second motor 52 and a third fan 53 connected to the output shaft of the second motor 52 are fixedly installed at one end of the exhaust pipe 51. An inner flow pipe 54 is connected to the top of the exhaust pipe 51, and an outer exhaust pipe 55 is connected to the back of the inner flow pipe 54.
[0062] The exhaust pipe 51 can directly discharge the internal gas to the outside after the second motor 52 and the third fan 53 are working. The discharge can be selective according to the actual situation. When the internal air humidity is high, it can be discharged to the outside and discharged into the designated external pipe. In order to improve the effect and efficiency of internal circulation, the suction force generated by the second motor 52 and the third fan 53 can be used to extract the internal heat and then transport it to the internal flow pipe 54. At this time, the solenoid valve on the external exhaust pipe 55 is closed. Conversely, when discharging gas to the external pipe, the solenoid valve on the internal flow pipe 54 is closed. When the gas is transported to the internal flow pipe 54 as described above, its solenoid valve is open. Then, after being transported, it is discharged again into the space where the heating pipe 46 is located, thereby increasing the gas flow rate and improving the heat energy utilization rate and working efficiency.
[0063] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
