[0014] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0015] like Figure 1 and Figure 2 As shown, a hot drying oven includes a furnace body 1 fixed on the workshop floor; the furnace body 1 has an opening on one side, and a pair of furnace doors 2 are hinged to the opening of the furnace body 1; the side walls and top of the furnace body 1 are both sandwiched, and the sandwich is filled with insulation material 11; two door-shaped air ducts 3 are fixed on the inner wall of the furnace body 1, and several heating tubes 4 are provided in each door-shaped air duct 3 on the two opposite side walls of the furnace body 1; an air inlet is opened at the middle position of each door-shaped air duct 3, and an air outlet 5 is opened at both ends of each door-shaped air duct 3, and each air outlet 5 is located at the inner bottom of the furnace body 1; a first centrifugal fan 6 is fixed at each air inlet at the inner top of the furnace body 1, and a second centrifugal fan 7 is also provided at the middle position of the inner top of the furnace body 1, and the second centrifugal fan 7 is located between the two door-shaped air ducts 3; a hot drying rack 8 is provided inside the furnace body 1, and the hot drying rack 8 is located above the air outlet 5.

[0016] In this hot drying oven, two sets of vent-shaped air ducts 3 are arranged close to the inner wall of the oven body 1. Each vent-shaped air duct 3 has an air inlet and a first centrifugal fan 6 in the middle. With the cooperation of the first centrifugal fan 6 and the vent-shaped air ducts 3, the airflow is drawn in through the air inlet located at the top of the oven body 1, heated by the heating tube 4, and discharged through the air outlet 5 located at the bottom of the oven body 1. After contacting the electromechanical parts on the hot drying rack 8, the airflow is drawn in again by the centrifugal fan (airflow path as follows). Figure 2 (As indicated by the arrow), thus continuously circulating the airflow to heat the electromechanical product components. The airflow inside furnace 1 can continuously circulate in the vertical direction, which not only facilitates uniform heating of the electromechanical product components but also improves the accuracy of measurement, control, and sampling, ultimately achieving energy saving, energy conservation, and emission reduction, thereby reducing energy loss and enhancing energy utilization.

[0017] The second centrifugal fan 7, located between the two-door air ducts 3, can continuously disperse the air inside the furnace body 1 to the surrounding areas, promote the lateral flow of airflow, make the temperature in all parts of the furnace body 1 more uniform, and further improve the uniformity of heating.

[0018] like Figure 1 As shown, a floor rail 9 is also provided on the workshop floor, extending into the furnace body 1; the bottom of the hot drying rack 8 is provided with several legs 81, each leg 81 is rotatably connected to a roller 82, and each roller 82 is rolled on the floor rail 9. Because the electromechanical product parts produced by our company are large in size and heavy in weight, they need to be placed in the oven by lifting equipment such as overhead cranes. The hot drying rack 8, which is slidably connected to the floor rail 9 by the rollers 82, can be easily moved outside the furnace body 1, thus facilitating the loading of electromechanical parts onto the hot drying rack 8 by lifting equipment.

[0019] like Figure 1 and Figure 3 As shown, a buffer plate 83 is provided at one end of the hot drying rack 8 near the inner side of the furnace body 1, and several sliding rods 84 are fixed on the buffer plate 83. Several through holes corresponding to each sliding rod 84 are opened on the hot drying rack 8, and each sliding rod 84 is inserted into the corresponding through hole. A spring 85 is sleeved on each sliding rod 84, and both ends of each spring 85 abut against the buffer plate 83 and the hot drying rack 8, respectively. A limiting nut 86 is provided on the end of each sliding rod 84 away from the buffer plate 83. The buffer plate 83 installed on the hot drying rack 8 through the sliding rods 84, springs 85, etc. can play a buffering role between the inner wall of the furnace body 1 and the hot drying rack 8 when the hot drying rack 8 slides into the hot drying furnace, which can effectively prevent the hot drying rack 8 from hitting and damaging the inner wall of the furnace body 1.

[0020] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
