[0022] In this embodiment, by setting combustion chambers 7 on both sides of the sintering chamber 1, and the combustion chambers 7 are equipped with burners, uniform and sufficient heat can be provided for the sintering process, ensuring that the zirconium corundum products are sintered in a suitable temperature environment, which helps to improve the quality and performance of the products. By setting an air inlet pipe on the sintering chamber 1, an inert gas input channel is provided, which can create an inert atmosphere during sintering, preventing the zirconium corundum products from reacting adversely with oxygen and other substances at high temperatures, and ensuring the purity and stability of the products. By setting an isolation net 11 on the inner wall of the sintering chamber 1 that can contact the adjustment frame 2, the distance between the adjustment frame 2 and the inner wall of the sintering chamber 1 is stabilized, preventing the adjustment frame 2 from shaking or shifting, ensuring the stability of the product position during the sintering process, and thus ensuring the consistency and reliability of the sintering effect.

[0023] In a further preferred embodiment of this utility model, the adjustment frame 2 is provided with a groove 20, and a movable wheel 12 for assisting the movement of the adjustment frame 2 is rotatably installed in the groove 20. The movable wheels 12 are arranged in groups. The movable wheels 12 located inside the sintering box 1 are in contact with the bottom inner wall of the sintering box 1, and the movable wheels 12 located outside the sintering box 1 are in contact with the ground.

[0024] In this embodiment, by setting a groove 20 on the adjusting frame 2 and rotating and installing the movable wheel 12 in the groove 20, the effect of assisting the movement of the adjusting frame 2 is achieved. The movable wheel 12 is arranged in groups.

[0025] In a further preferred embodiment of the present invention, the sintering box 1 is composed of a heat-conducting layer 8, a heat-insulating layer 9 sleeved outside the heat-conducting layer 8 for heat preservation, and a heat-insulating layer 10 disposed outside the heat-insulating layer 9 for heat insulation to prevent burns. The top of the sintering box 1 is provided with a heat dissipation mechanism for assisting heat dissipation.

[0026] In this embodiment, by setting up a sintering box 1 composed of a heat-conducting layer 8, a heat-insulating layer 9, and a heat-insulating layer 10, multiple functions are optimized. The heat-conducting layer 8 can efficiently conduct the heat generated by the burner to the inside of the sintering box 1, ensuring that the zirconium corundum product is heated evenly. The heat-insulating layer 9, which is set outside the heat-conducting layer 8, plays a good role in heat preservation, reducing heat loss, reducing energy consumption, and improving sintering efficiency. The heat-insulating layer 10, which is set outside the heat-insulating layer 9, effectively isolates heat, prevents operators from being burned, and ensures operational safety. In addition, the heat dissipation mechanism set at the top of the sintering box 1 can assist in heat dissipation and facilitate rapid cooling of the sintered zirconium corundum.

[0027] In a further preferred embodiment of the present invention, the heat dissipation mechanism includes an exhaust port 16 fixed to the top of the sintering box 1, a plug 17 threadedly installed in the exhaust port 16 for sealing the exhaust port 16, and a baffle 18 fixed to the top of the plug 17 for assisting in sealing the exhaust port 16.

[0028] In this embodiment, an exhaust port 16 fixed to the top of the sintering chamber 1 provides a channel for heat dissipation within the sintering chamber 1, allowing excess heat to be discharged promptly when needed, preventing excessively high temperatures from adversely affecting the equipment and zirconia-corundum products. A plug 17 threaded into the exhaust port 16 effectively seals the exhaust port 16, preventing heat loss and external impurities from entering the sintering chamber 1 when heat dissipation is not required, thus ensuring a stable sintering environment. A baffle 18 fixed to the top of the plug 17 further assists in sealing the exhaust port 16, enhancing the sealing effect. It also allows operators to easily install or remove the plug 17 by rotating the baffle 18, enabling flexible control of the opening and closing of the exhaust port 16. This makes temperature regulation of the sintering chamber 1 more convenient and efficient, contributing to improved sintering quality and equipment operational stability.

[0029] In a further preferred embodiment of the present invention, a handle 19 for providing an operating grip point is installed on the baffle 18, a vent is provided on the combustion chamber 7, a dustproof net is installed inside the vent, and a protective door for closing the sintering chamber 1 is detachably installed on the sintering chamber 1.

[0030] In this embodiment, by installing a handle 19 on the baffle 18, a convenient operating grip point is provided for the operator, making it easier and less strenuous to rotate the baffle 18 to open or close the block 17, thus improving the convenience and efficiency of operation. The combustion chamber 7 is provided with a vent to ensure that sufficient air enters during combustion, maintaining the stability of combustion. At the same time, a dustproof net is installed inside the vent to effectively block dust and other impurities from entering the combustion chamber 7, preventing impurities from affecting the normal operation of the burner and extending the service life of the burner. A protective door can be detachably installed on the sintering chamber 1, which can be sealed during the sintering process to prevent heat loss and external interference, ensuring the stability of the sintering environment. After sintering, it can be easily opened to facilitate the removal of the product. This design takes into account both the sealing of the sintering process and the convenience of operation.

[0031] In a further preferred embodiment of the present invention, the bottom of the adjusting frame 2 is provided with a guide groove for limiting the moving path of the adjusting frame 2, the support roller 15 is in contact with the inner wall of the guide groove, and both the support frame 4 and the isolation plate 5 are provided with through holes for assisting heat flow.

[0032] In this embodiment, by setting a guide groove at the bottom of the adjusting frame 2 to limit the movement path of the adjusting frame 2, the effect of standardizing the movement trajectory of the adjusting frame 2 is achieved, so that the adjusting frame 2 can remain stable during movement, avoiding deviation or shaking, and improving the accuracy and reliability of the movement of the adjusting frame 2. The support roller 15 is in contact with the inner wall of the guide groove, which not only supports the adjusting frame 2, but also assists the adjusting frame 2 to move smoothly along the guide groove, further ensuring the stability of the movement of the adjusting frame 2. Through holes for assisting heat flow are set on both the support frame 4 and the isolation plate 5, so that the heat in the sintering box 1 can be distributed more evenly, ensuring that all parts of the zirconium corundum product can be fully heated, which helps to improve the uniformity of sintering and the quality of the product, making the entire sintering process more efficient and reliable.

[0033] In summary, compared with related technologies, this device, through the movable installation of the adjusting frame 2 and the rotatable design of the support frame 4, can flexibly adjust the position and angle of the support frame 4 to meet different sintering and loading / unloading requirements. The isolation plate 5 set on the support frame 4 realizes layered isolation, avoids product stacking and tipping, and improves sintering safety. The support block 6 and the support structure provide auxiliary support and enhance the stability of the device.
