Description

Technical Field

[0001] The utility model relates to the technical field of hot repair and maintenance of regenerators in glass furnaces, and particularly relates to a device for hot replacement of the arch of a divided regenerator in a glass furnace. Background Art

[0002] The regenerator is an important part of a glass furnace, which plays the role of preheating combustion-supporting air by using the waste heat of exhaust gas, can improve the thermal efficiency of the furnace and reduce the fuel consumption. With each commutation in the glass furnace, the combustion-supporting air and flue gas in the regenerator are replaced once. When passing exhaust gas, the exhaust gas itself contains multi-component gases such as SO2, and at the same time, unmelted powder will also be carried into the regenerator. Long-term use will cause erosion of the arch, wall and checkerwork of the regenerator. As an important part of the regenerator, for a long time, if the arch of the regenerator is severely eroded or faces collapse due to other reasons, the glass furnace often stops production as a whole for cold repair, resulting in huge economic losses.

[0003] When the arch of a regenerator unit faces collapse, the method of overall replacement can be adopted. However, the temperature inside the regenerator is high and the structure of the regenerator is not easy to operate on the arch. Therefore, how to conveniently replace the arch of the regenerator has always been a difficult problem. Content of the Utility Model

[0006] A second support steel structure, which is arranged above the first support steel structure and is vertically connected to the first support steel structure;

[0007] A regenerator arch assembly, which is arranged below the second support steel structure and is slidably connected to the second support steel structure;

[0008] A driving assembly, including a driving mechanism arranged above the second support steel structure and a traction member respectively connected to the driving mechanism and the regenerator arch assembly; the traction member is driven by the driving mechanism to traction the regenerator arch assembly to move along the lower end surface of the second support steel structure towards the regenerator structure.

[0009] Further, the regenerator arch assembly includes a regenerator arch and a brick clamping steel structure connected to the top of the regenerator arch;

[0010] The regenerator arch is an integral structure formed by biting several flat arch bricks. Each single flat arch brick includes a clamping top brick, a first flat arch brick body and a second flat arch brick body which are fixedly connected from top to bottom;

[0011] The snap-on coping brick has a "T" - shaped structure, and the groove that is recessed inward between the upper end surface of the snap-on coping brick and the upper end surface of the first skewback brick body is the brick clip steel snap-in groove.

[0012] Further, the first skewback brick body and the second skewback brick body are rectangular structures with the same size;

[0013] The first skewback brick body and the second skewback brick body are arranged staggeredly, so that any vertical side wall of the first skewback brick body and the corresponding vertical side wall on the second skewback brick body are not on the same vertical plane;

[0014] The area on the upper end surface of the second skewback brick body that does not overlap with the lower bottom surface of the first skewback brick body is the biting and laying surface.

[0015] Further, the edge where the upper end surface of the first skewback brick body meets the vertical side wall is chamfered.

[0016] Further, the brick clip steel structure includes a plurality of vertical steel frames and connecting beams for connecting the vertical steel frames. A running wheel is provided at the top of the vertical steel frame, and a clamping platform matching the brick clip steel snap-in groove is provided at the bottom of the vertical steel frame.

[0020] Further, the skewback brick is made of zircon mullite.

[0021] Further, the regenerator structure includes a regenerator, a regenerator wall body wrapping the periphery of the regenerator, a small furnace communicated with the regenerator, and a glass melting furnace connected to the small furnace.

[0022] Further, sealing material is filled in the brick joints between two adjacent skewback bricks.

[0023] Compared with the prior art, the beneficial effects of the present utility model are:

[0024] 1. The bricks of the split regenerator arch of the glass melting furnace for hot replacement in the present utility model are made of zircon mullite, which can be relatively resistant to flue gas erosion and have a relatively long service life.
