Description

Technical Field

[0001] This utility model relates to the field of industrial kiln technology, and more specifically to the field of an automatic adjustment device for thermal expansion of the arch foot of a kiln regenerator. Background Technology

[0002] Kiln regenerators are crucial energy-saving and environmentally friendly devices in industrial kilns (especially in the glass, metallurgy, and ceramics industries). A kiln regenerator is a heat exchange device that uses refractory materials as heat storage media (or checker bricks) to periodically absorb waste heat from high-temperature flue gas and use this heat to preheat combustion air or fuel gas. When high-temperature exhaust gas passes through the kiln, the refractory bricks in the regenerator absorb and store the heat of the exhaust gas (like a battery charging). When the valve is switched, the cold combustion air passes through the regenerator in the opposite direction, and the refractory bricks release the stored heat to the air, heating it to hundreds or even thousands of degrees Celsius. This process repeats continuously, greatly recovering the heat carried away by the exhaust gas.

[0003] Currently, when the temperature inside the furnace of the glass kiln regenerator is baked from 0℃ to 1300℃, the walls of the kiln regenerator expand and the upper part shifts. The top screws of the arch foot steel plate support bolts are manually adjusted to ensure that the horizontal tangential force of the furnace structure is evenly distributed. However, the manual adjustment method is time-consuming, labor-intensive and inefficient. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic adjustment device for thermal expansion of the arch foot of a kiln regenerator in order to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution: This utility model provides an automatic thermal expansion adjustment device for the arch foot of a kiln regenerator, including an inner pulley plate fixedly connected to the arch foot steel plate and used to fix the arch foot bricks, an outer pulley plate disposed on the outside of the inner pulley plate, and a pulley assembly disposed between the inner pulley plate and the outer pulley plate; the pulley assembly is fixedly disposed on the outer pulley plate and is slidably connected to the inner pulley plate; the device also includes an adjustable support bolt set screw assembly for adjusting the distance between the outer pulley plate and the inner pulley plate.

[0006] Specifically: The inner side plate of the pulley is connected to the arch foot steel to fix the arch foot bricks. During the baking process in the regenerator of the glass kiln, when the temperature inside the kiln rises from 0℃ to 1300℃, the walls of the regenerator expand and the upper part shifts. The inner side plate of the pulley moves upward synchronously with the arch foot steel plate. Since the limiting tube of the outer side plate of the pulley is connected to the support bolt and does not move up and down, the pulley assembly fixed to the outer side plate of the pulley will not move up and down. The pulley assembly slides in contact with the inner side plate of the pulley, reducing friction and protecting the arch foot bricks from damage, ensuring that the horizontal tangential force on the arch foot bricks is evenly distributed.

[0007] In one embodiment, the support bolt set screw assembly includes a set screw mounting part and a support bolt set screw that is threadedly connected to the set screw mounting part. The support bolt set screw is threadedly connected to the outer side plate of the pulley.

[0008] In one embodiment, multiple limiting tubes are provided on the outer side of the pulley outer plate; each limiting tube is connected to the support bolt set screw through a threaded engagement.

[0009] In one embodiment, there are two limiting tubes, which are welded to the outer side of the pulley outer plate in an upper and lower configuration. Each limiting tube has an internal thread on its inner side, and the axis of each limiting tube is perpendicular to the pulley outer plate.

[0010] In one embodiment, a pulley support plate is provided at the bottom outer side of the pulley outer plate.

[0011] In one embodiment, the pulley assembly includes a square pulley frame and a plurality of pulley columns that are evenly distributed within the square pulley frame, wherein the plane of the square pulley frame is parallel to the outer side plate of the pulley.

[0012] In one embodiment, the two long sides of the square pulley frame are vertically arranged, and the two short sides of the square pulley frame are horizontally arranged longitudinally. The two ends of each pulley column are mounted on the two long sides of the square pulley frame by a rotating installation method.

[0013] In one implementation, the pulley columns are arranged horizontally and longitudinally.

[0014] In one implementation, several pulley columns are arranged at equal intervals from top to bottom.

[0015] In one embodiment, both the inner and outer plates of the pulley are square plates, and the inner and outer plates are parallel to each other.

[0016] During the drying process of the regenerator, the walls expand and the upper part shifts. The arch steel plate is automatically adjusted according to the displacement distance of the walls to support the horizontal load-bearing capacity of the furnace structure.

[0017] The beneficial effects of this utility model are as follows: This utility model has a reasonable design. The inner side plate of the pulley is connected to the arch foot steel to fix the arch foot bricks. When the glass kiln regenerator is heated, as the temperature inside the kiln increases from 0℃ to 1300℃, the walls of the kiln regenerator expand and the upper part shifts. The inner side plate of the pulley moves upward synchronously with the arch foot steel plate. Since the limiting tube of the outer side plate of the pulley is connected to the support bolt and does not move up and down, the pulley assembly fixed to the outer side plate of the pulley will not move up and down. The pulley assembly slides in contact with the inner side plate of the pulley, reducing friction and protecting the arch foot bricks from damage, ensuring that the horizontal tangential force on the arch foot bricks is evenly distributed.
