Background Art

[0002] The slidable wear-resistant and heat-insulating slider used for sealing the furnace tubes at the top of the heating furnace is a sliding pad made of wear-resistant material, which is usually used to prevent friction and wear between the furnace tubes and the furnace roof. These sliders have good wear resistance and heat insulation properties, which can protect the furnace tubes and the furnace roof and extend the service life of the equipment. In addition, these sliders also have good sliding performance, which can ensure the smooth operation of the furnace tubes during operation.

[0003] When the slidable wear-resistant insulating slider is in use, the slider cannot be installed with furnace tubes of different sizes, which will result in an unstable connection between the furnace tube and the slider, thus causing safety hazards. Therefore, the market needs a new device to solve the current problems. Utility Model Content

[0006] Preferably, a clamping plate is fixed at the left and right ends of the fixing column, and a stainless steel spring is sleeved on the outer wall of the fixing column at the left and right sides.

[0007] Preferably, when the screw rod is extended in length, the clamping plate moves at an inner position, and the clamping plate is clamped at the inner position of the screw rod so that the fixing column and the screw rod will not separate.

[0008] Preferably, the movement of the clamping plate causes compression on the stainless steel spring sleeved at an outer position of the fixing column.

[0009] Preferably, the lower circular frame can be moved to a lower position through the clamping plate, and the movement of the lower circular frame enables the furnace tube with a larger diameter to be inserted into the inner position.

[0010] Preferably, the clamping plate moves at an inner position of the upper circular frame and the lower circular frame, and the movement of the clamping plate causes compression on the stainless steel spring sleeved at the outer wall position of the arc column.

[0014] When the lower slider is installed with a larger-sized furnace tube, the furnace tube squeezes the lower circular frame, causing the lower circular frame to extend through the arc column. The movement of the arc column causes the clamping plate to squeeze the stainless steel spring. At the same time, the screw is extended in length according to the diameter of the furnace tube through the fixed column. The fixed column squeezes the stainless steel spring through the clamping plates at the left and right ends. The stainless steel spring releases the elastic force so that the upper slider and the lower slider are tightly attached to the outer wall of the furnace tube. In this way, furnace tubes of different sizes can be installed, which can ensure the stability of the connection between the slider and the furnace tube and reduce safety hazards.

[0015] The device divides the slider into an upper slider and a lower slider. The lower slider is connected to the internal position of the slot in the upper slider. At the same time, the slot at the upper end of the lower slider is slidably connected to the fixed bar at the lower end of the upper slider. When the fixed bar completely enters the internal position of the slot, the upper slider and the lower slider are completely installed. Dividing the slider into an upper slider and a lower slider can realize distributed force, reduce the stress of a single slider, reduce the wear and failure risk of the slider, and thus improve the reliability of the entire heating system.
