Utility Model Content

[0004] The purpose of the present utility model is to provide a high-temperature box-type resistance furnace with a protective structure to solve the problem that the high-temperature box-type resistance furnace proposed in the above background technology lacks a protective structure, and when the user opens the furnace door, the heat waves or high-temperature gases in the furnace can easily cause burns to the user, thereby reducing the safety of the high-temperature box-type resistance furnace.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-temperature box-type resistance furnace with a protective structure, comprising an equipment housing, a furnace door, an emergency switch, a temperature sensor and a controller, the furnace body being installed in the equipment housing, a guide rail being provided on the equipment housing, a slider being installed on the furnace door, the slider being slidably connected to the guide rail, a temperature sensor and a controller being installed on the equipment housing, a slide being provided on the equipment housing, an electric telescopic rod being installed in the slide, a safety rod being installed at one end of the electric telescopic rod, a safety hole being provided on the furnace door, the safety rod being fitted with the safety hole, and the controller being connected to the temperature sensor and the electric telescopic rod.

[0006] By adopting the above technical solution, the material to be calcined is placed in the furnace body installed in the equipment casing, and the furnace door is pulled up through a sliding connection between the guide rail provided on the equipment casing and the slider installed on the furnace door. When the furnace body is in operation, the temperature in the high-temperature box-type resistance furnace can be detected by the temperature sensor installed on the equipment casing, and the measured temperature value is transmitted to the controller. When the detected temperature value is higher than the maximum temperature value set in the controller, the controller controls the electric telescopic rod installed in the slide to extend, driving the safety rod installed at one end of the electric telescopic rod to move toward the direction of the furnace door, so that one end of the safety rod is inserted into the safety hole provided on the furnace door, thereby limiting and fixing the furnace door. When it is detected that the temperature value in the high-temperature box-type resistance furnace is lower than the minimum temperature value set in the controller, the controller controls the electric telescopic rod installed in the slide to retract, driving the safety rod installed at one end of the electric telescopic rod to retreat, so that one end of the safety rod is withdrawn from the safety hole opened on the furnace door, thereby releasing the limit fixation of the furnace door.
