[0020] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the drawings and specific implementation methods of the specification. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] like Figure 1 , Figure 2 The temperature-monitorable silica sol shell baking electric furnace shown in the figure comprises an electric furnace body 1, which is a rectangular structure, and has a furnace cavity 11 formed inside the electric furnace body 1. A plurality of electric heaters 2 are respectively installed on both sides of the furnace cavity 11, and the electric heaters 2 are electrically connected to the controller of the electric furnace. The furnace cavity 11 is connected to the front side of the electric furnace body 1 to form an opening 12, and a furnace door 13 is installed at the opening 12 so as to be liftable.

[0022] Specifically, guide rails are installed on both sides of the opening 12, and both sides of the furnace door 13 are slidably connected to the guide rails through sliders. A lifting mechanism 14 is installed on the top of the front side of the electric furnace body 1. The lifting mechanism 14 can be a winch, a cylinder, a hydraulic cylinder, an electric telescopic rod, etc. The lifting mechanism 14 of this embodiment is a winch. When the winch rope is wound, the furnace door 13 rises along the guide rail to open the opening 12. When the winch rope is unwound, the furnace door 13 descends along the guide rail to close the opening 12.

[0023] like Figure 2-4 As shown, a temperature measuring hole 15 is provided on the top of the electric furnace body 1, which is a trumpet-shaped structure with a small top and a large bottom. A temperature measuring mechanism 3 is installed on the top of the temperature measuring hole 15. The temperature measuring mechanism 3 includes a temperature measuring tube 31, and the upper end of the temperature measuring tube 31 is installed on the upper end of the temperature measuring space 15 through a joint bearing 32, so that the temperature measuring tube 31 is inserted into the temperature measuring hole 15.

The blowing pipe 33 is located between the flange 311 and the spherical bearing 32 and is used to slowly blow air into the temperature measuring tube 31 to achieve the isolation of the temperature in the furnace from the infrared thermometer 35, while reducing the influence of blowing on the temperature in the furnace.

[0025] Preferably, a receiving groove 16 is provided on the side wall at the lower end of the temperature measuring hole 15, and the receiving groove 16 is in a circular ring shape, and a partition 36 is movably installed in the receiving groove 16.

A through hole is provided in the center of the partition 36, and the temperature measuring tube 31 is inserted in the through hole. When the temperature measuring tube 31 is rotated, the partition 36 can move with the temperature measuring tube 31, and at the same time, the temperature measuring hole 15 is shielded, thereby reducing the heat loss in the furnace cavity 11.

[0026] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0027] 1. The temperature of the product can be directly measured by the infrared thermometer, which improves the accuracy of temperature monitoring in the furnace and ensures the quality of the product;
