Description

Technical Field

[0001] This utility model belongs to the field of metallurgical technology, and in particular relates to a high-temperature sintering furnace for smelting silicon carbide porous ceramics. Background Technology

[0002] Silicon carbide porous ceramics possess properties such as high hardness, high wear resistance, corrosion resistance, and high temperature resistance, making them widely used. Currently, high-temperature sintering furnaces are mainly used to smelt silicon carbide porous ceramics. During the high-temperature sintering process, the binder produces tar during high-temperature pyrolysis. Although some of the tar is extracted from the furnace by the vacuum unit, some remains. This residual tar usually adheres to the inner wall of the furnace. Long-term adhesion of tar affects the heating rate of the furnace's internal resistance and can also cause corrosion inside the furnace, affecting the normal operation of the sintering furnace. Therefore, it is necessary to clean the tar remaining on the inner wall of the furnace.

[0003] A search revealed a high-temperature sintering furnace for silicon carbide porous ceramic smelting, disclosed in patent publication number CN212082063U. The furnace includes a base, an arc-shaped groove, and a furnace body. A brush rod is installed inside the furnace body, and a cleaning device is provided on the surface of the brush rod. A turntable is movably connected to the left end of the brush rod, and a moving device is located on the right side of the turntable. A motor is fixedly connected to the other side of the turntable, and a connecting plate is fixedly connected to the left end of the motor. A base is fixedly connected to the lower end of the connecting plate. The motor drives the turntable to rotate, which in turn drives the brush rod to rotate, cleaning the interior of the furnace. This eliminates the need for manual cleaning of the sintering furnace, saving time and reducing the labor intensity of operators, thus extending the service life of the sintering furnace and increasing production efficiency.

[0004] The aforementioned high-temperature sintering furnace for silicon carbide porous ceramics has a turntable with one side fixedly connected to the output end of a motor. A groove is formed on the other side of the turntable. A spring is fixedly connected to one end of the groove near the outer surface of the turntable, and a brush rod is fixedly connected to the other end of the spring. A pin is movably connected to the other side of the brush rod (the pin is an existing structure and will not be described in detail here). A row of pin holes is formed on the rear wall inside the groove. There are four grooves arranged in a cross shape on one side of the turntable. The four grooves have identical internal structures. The spring allows the brush rod to move within the groove. When it reaches a designated position, the pin is inserted into the pin hole, fixing the brush rod in the designated position. However… Multiple pins need to be inserted and removed one by one to adjust the position of different brush rods, increasing the number of operation steps and workload. In addition, the furnace body is equipped with a roller brush device, which includes a base two. A connecting plate is fixedly connected to the upper surface of the base two. A motor is fixedly connected to the center of the right side surface of the connecting plate. A turntable is fixedly connected to the output end of the motor. When the motor is started, the rotation of the motor output end drives the turntable to rotate, and the rotation of the turntable drives the brush rod to rotate. However, operating the motor can only drive the brush rod to rotate, which is not convenient for adjusting the height of the brush rod, nor for adjusting the height of the brush rod according to the height of the furnace body, and it is not convenient for cleaning the furnace body at different heights, thus reducing the applicability.

[0005] To address these issues, we provide a high-temperature sintering furnace for smelting porous silicon carbide ceramics. Summary of the Invention
