[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In the embodiment, Figure 1-6 Provided is an electric hot air drying oven for producing refractory plates, comprising a drying oven 1, the bottom end of the drying oven 1 is fixedly connected with four feet 2, the front end of the drying oven 1 is hinged with a switch door 3, the inner side of the switch door 3 is fixedly connected with a glass 4, the front end of the switch door 3 is fixedly connected with an iron sheet 5, the front end of the iron sheet 5 is fixedly connected with a door handle 6, the drying oven 1 is fixedly connected with a magnetic sheet 7, the inner side of the drying oven 1 is fixedly connected with a drying liner 9, the inner side of the drying liner 9 is fixedly connected with a stainless steel partition 10, and the stainless steel partition 10 is provided with a plurality of through holes 11, A drying assembly 12 is provided on the inner side of the drying box 1, the rear end of the drying box 1 is connected to an air inlet rear cover 13, the top of the drying box 1 is detachably connected to an air outlet cover 14 by bolts, the air outlet cover 14 is provided with four first air outlets 15, the top of the drying box 1 is provided with a ventilating hole 16 connected to the four first air outlets 15, the top of the air outlet cover 14 is detachably connected to an air outlet top cover 17 by bolts, the air outlet top cover 17 is provided with four second air outlets 18 which are the same size and shape as the first air outlets 15, and the air outlet top cover 17 can rotate along the bolts.

[0024] Through the above arrangement, the air outlet top cover 17 is rotated to connect the four second air outlets 18 with the four first air outlets 15. The staff member holds the door handle 6 and rotates the switch door 3 to open it, and puts the refractory plate coated with refractory material together with the baking rack in the drying box 1. The staff member holds the door handle 6 again and rotates the switch door 3 to close it. The magnetic suction sheet 7 attracts the iron sheet 5, so that the switch door 3 will not be displaced without external force. The drying component 12 is started, and the drying component 12 will inhale air from the air inlet rear cover 13 and send it into the drying box 1 through a plurality of through holes 11 after heating. Part of the hot air flows out from the vent 16 through the first air outlet 15 and the second air outlet 18 to dry the refractory plate coated with refractory material. When the refractory plate is not dried, the air outlet top cover 17 can be rotated so that the air outlet top cover 17 blocks the four first air outlets 15 to prevent dust and flying insects from falling into the drying box 1. It should be noted that a sealing ring is provided on the inner side of the switch door 3 to prevent hot air from escaping from the door gap.

[0025] Reference Figure 1-6 , wherein the drying assembly 12 includes a driving motor 121, the driving motor 121 is fixedly connected to the inner side of the drying box 1, the output end of the driving motor 121 is fixedly connected to a supply fan 122, the supply fan 122 is located at the rear side of the plurality of through holes 11, and a heating pipe 123 is fixedly connected to the inner side of the drying box 1;

[0026] Through the above-mentioned structural arrangement, the driving motor 121 is started, and the driving motor 121 can drive the supply fan 122 to rotate. The supply fan 122 sucks air through the air inlet rear cover 13 and sends it into the drying box 1. The heating tube 123 is energized, and the air around the heating tube 123 and the heated air are sent into the drying box 1 by the supply fan 122 to dry the refractory plate in the drying box 1.

[0027] Reference Figure 1-6 , wherein an over-temperature protector 8 is fixedly connected to the inner side of the drying box 1, a temperature sensor is arranged on the inner wall of the drying liner 9, and the over-temperature protector 8 is electrically connected to the temperature sensor;

[0028] Through the above-mentioned structural setting, the over-temperature protector 8 monitors the temperature inside the drying box 1 through the temperature sensor. When the temperature inside the drying box 1 exceeds a predetermined temperature, the over-temperature protector 8 will cut off the power to the heating tube 123 to prevent it from further generating heat.
