[0016] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0017] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0018] The utility model provides a pre-oxidation furnace protection device, comprising a furnace body 1, the furnace body 1 is a hollow open structure, a sealing plate 2 is rotatably connected at the opening 101 of the furnace body 1, the sealing plate 2 is made of hard alloy material, an interlayer is arranged in the sealing plate 2, the interlayer of the sealing plate 2 is filled with a heat insulation layer 201, a trolley 3 is slidably connected in the furnace body 1, a material to be oxidized 301 is installed on the trolley 3, a combustion box 4 is installed on one side of the furnace body 1, and the combustion box 4 and the bottom of the furnace body 1 are connected by a conveying pipe 102 is connected, a smoke outlet 103 is arranged on the top of the furnace body 1, an oxygen supply machine 5 is installed on the right side of the smoke outlet 103, the oxygen supply machine 5 is connected to the furnace body 1 through an air pipe 501, the limit plate 203 is connected to the furnace body 1 through a bolt 204, the cross section of the limit plate 203 is L-shaped, a handle 205 is fixedly connected to the sealing plate 2, and the hinge rotation point 206 between the sealing plate 2 and the furnace body 1 is located on the left side of the sealing plate 2, and the sealing performance of the connection between the sealing plate 2 and the furnace body 1 is greatly improved;

[0019] When the pre-oxidation furnace protection device is actually used, the staff will deliver the cart 3 structure loaded with the material to be oxidized 301 into the furnace body 1, and then the staff will manually operate the sealing plate 2 to rotate around the hinge rotation point 206 until the limit plate 203 on the sealing plate 2 abuts against the outer wall of the furnace body 1. Since the cross-section of the limit plate 203 is L-shaped, it is convenient for the limit plate 203 and the furnace body 1 to abut against each other and then be fixedly connected with the bolts 204 to complete the sealing work of the sealing plate 2 on the opening 101 of the furnace body 1. Then, the combustion box 4 cooperates with the delivery pipe 102 to deliver high-temperature gas to the furnace body 1, and at the same time, the oxygen supplier cooperates with the gas pipe 501 to deliver oxygen to the furnace body 1. The high-temperature gas combines with oxidation to complete the oxidation treatment of the material to be oxidized 301. After the high-temperature gas completes the oxidation treatment, it is discharged from the exhaust pipe position. A sandwich structure is arranged in the middle, and a heat insulating layer 201 is arranged at the position of the sandwich, so that the high-temperature heat transported to the furnace body 1 is not easy to dissipate, and a sealing ring is arranged on the inner wall of the sealing plate 2 to complete the sealing work at the joint between the sealing plate 2 and the furnace body 1. The sealing plate 2 is made of cemented carbide material, and a heat insulating layer 201 is arranged in the sealing plate 2 to keep the temperature of the furnace body 1 warm. The sealing ring structure design plays the role of heat preservation at the joint between the sealing plate 2 and the furnace body 1.

[0021] The effect achieved by the entire embodiment 1 is that, during use, by setting a combustion supply port on the top of the combustion box 4, it is convenient for the staff to supply the combustion box 4, and the structural design of the inspection port 402 is easy for the staff to make timely adjustments.

[0022] Working principle: the staff will deliver the cart structure loaded with the material to be oxidized into the furnace body, and then the staff will manually operate the sealing plate to rotate around the hinged rotation point until the limit plate on the sealing plate abuts against the outer wall of the furnace body. Since the cross-section of the limit plate is L-shaped, it is convenient for the limit plate and the furnace body to abut and then be fixed with bolts to complete the sealing work of the sealing plate at the opening position of the furnace body. Then the combustion box cooperates with the delivery pipe to deliver high-temperature gas to the furnace body, and at the same time, the oxygen supply cooperates with the gas pipe to deliver oxygen to the furnace body. The high-temperature gas is combined with oxidation to complete the oxidation treatment of the material to be oxidized. After the oxidation treatment, the high-temperature gas is discharged from the exhaust pipe position. Since a sandwich structure is arranged in the sealing plate, an insulation layer is arranged at the sandwich position, so that the high-temperature heat delivered to the furnace body is not easily lost. At the same time, a sealing ring is arranged on the inner wall of the sealing plate to complete the sealing work at the joint between the sealing plate and the furnace body.
