Technical Field
[0001] This utility model relates to the field of oxidation furnace technology, and more specifically, to an oxidation furnace with an adjustable internal space structure. Background Technology
[0002] An oxidation furnace is a common laboratory piece of equipment. It is a precisely designed and manufactured high-temperature electric furnace that uses oxygen or air to oxidize or reduce substances under high-temperature conditions. Oxidation furnaces are widely used in chemistry, biology, materials science, environmental science, and other fields. In chemistry, it is an important tool for laboratory analysis and synthesis, used to determine and synthesize compounds, and to effectively control reaction conditions. In biology, it can be used for the thermal denaturation and degradation of proteins, thereby revealing their structure and function. In materials science, it can be used for surface treatment and thin film preparation. In environmental science, it can be used for air pollution control and solid waste treatment. However, existing oxidation furnaces have a fixed internal space, requiring heating the entire space even when oxidizing smaller substances, resulting in energy waste. Therefore, we propose an oxidation furnace with an adjustable internal space structure. Utility Model Content

Movable seats 4 are threaded onto the outer sides of both ends of the first bidirectional lead screw 3. The ends of the two movable seats 4 extend into the inner cavity of the furnace box 1 and are fixedly connected to movable side plates 5. A first motor 6 is fixedly installed on the side of the furnace box 1. The output shaft of the first motor 6 is connected to the end of the first bidirectional lead screw 3.

[0026] For details, please refer to Figures 2 to 4 The lifting and adjusting mechanism 7 includes a movable groove 10 formed on the bottom surface of the inner cavity of the furnace box 1 and a second motor 11 fixedly installed on the side of the furnace box 1.

Lifting seats 15 are rotatably connected to the top ends of the two support frames 14. Telescopic grooves 16 are provided at both ends of the lifting seats 15.

[0027] In this embodiment, the threaded engagement between the second bidirectional lead screw 12 and the two sliders 13 drives the two sliders 13 to move closer or further apart. The movement of the sliders 13 causes the support frame 14 to move the lifting seat 15 up and down, thereby adjusting the size of the space inside the furnace box 1.
[0028] For details, please refer to Figures 1 to 3An air inlet pipe 19 is fixedly connected to the rear of the furnace box 1, an igniter 20 is fixedly installed on the top of the inner cavity of the furnace box 1, an exhaust pipe 21 is fixedly connected to the top of the furnace box 1, and an electric control valve 22 is fixedly installed on the top of the exhaust pipe 21.
[0029] In this embodiment, the externally mixed combustion gas and oxygen are introduced into the inner cavity of the furnace box 1 through the air inlet pipe 19. The combustion gas is ignited by the igniter 20. The heat generated by the combustion of the combustion gas causes the oxygen to oxidize the material. The exhaust gas generated by the combustion is discharged through the exhaust pipe 21 and the electric control valve 22. The end of the electric control valve 22 is connected to the external exhaust gas purification treatment equipment.
[0030] For details, please refer to Figure 1 and Figure 2 A control panel 23 is fixedly installed on the side of the furnace box 1. The control panel 23 is electrically connected to the first motor 6, the second motor 11, the electric control valve 22, and the igniter 20.

[0035] In this embodiment, the inner wall of the movable groove 10 is used to limit the slider 13, so that the slider 13 can only move along the axial direction of the second bidirectional lead screw 12.

[0038] Working principle: During use, the internal space of the furnace box 1 is adjusted according to the size of the material. First, the first motor 6 is started to drive the first bidirectional lead screw 3 to rotate. Through the threaded engagement between the first bidirectional lead screw 3 and the two moving seats 4, the two moving seats 4 are moved closer or further apart. At the same time, the moving seats 4 drive the two moving side plates 5 to move closer or further apart, thereby adjusting the lateral space of the furnace box 1. In addition, when the moving side plates 5 move, they push the telescopic plate 18 to retract into the inner cavity of the telescopic groove 16 or extend out of the inner cavity of the telescopic groove 16. Then, the second motor 11 is started to drive the second bidirectional lead screw 12 to rotate. The threaded engagement between the two-way lead screw 12 and the slider 13 causes the two sliders 13 to move closer or further apart. The movement of the sliders 13 causes the support frame 14 to move the lifting seat 15 and the telescopic plate 18 up and down, thereby adjusting the vertical space of the furnace box 1. Finally, the furnace door 8 is opened and the material to be oxidized is placed on the lifting seat 15 and the telescopic plate 18. The mixed combustion gas and oxygen from the outside are introduced into the inner cavity of the furnace box 1 through the air inlet pipe 19. The combustion gas is ignited by the igniter 20. The heat generated by the combustion of the combustion gas is used to oxidize the material. The exhaust gas generated by the combustion is discharged through the exhaust pipe 21 and the electric control valve 22.
