Technical Field

[0001] The utility model relates to the technical field of thermal repair and heat insulation protection of coke ovens, in particular to a thermal repair and heat insulation protection device for coke ovens. Background Art

[0002] A coke oven is a furnace used to produce coke. Modern coke ovens consist of a carbonization chamber, combustion chamber, regenerator, chute area, roof, foundation, and flue. In the carbonization chamber, coal is heated in an airtight environment to form coke. The lifespan of a coke oven generation is generally around 25 years, but with good operation and maintenance, it can last over 30 years. During hot repairs, due to the high temperatures, thermal insulation devices are required to protect workers.

[0003] The width of the existing coke oven thermal repair insulation protection device is fixed. When the bottom of the coke oven is repaired at a fixed point for a long time, heat will be generated on the inner wall and top of the coke oven. The existing insulation protection device does not protect the sides and top of the workers, which will still cause discomfort to the workers. At the same time, when repairing a wider coke oven, the existing insulation protection device cannot completely seal the coke oven, resulting in poor protection effect of the insulation protection device. Utility Model Content

[0004] The purpose of the utility model is to provide a coke oven thermal repair insulation protection device, which has the characteristics of protecting the sides and top of the workers, facilitating the adjustment of the width of the insulation protection device, and increasing the protection effect of the insulation protection device.

[0007] In order to drive the two mounting plates to move in opposite directions, as a preferred coke oven thermal repair and insulation protection device of the present invention, a first cavity is opened inside the base, and the left and right side walls of the base are penetrated by notches connected to the first cavity. The opposite side walls of the two mounting plates are fixedly connected with racks extending into the first cavity through the notches, and the interior of the first cavity is rotatably connected with a gear located between the two racks and meshing with the two racks.

[0008] In order to drive the second insulation plate to rotate, as a preferred coke oven thermal repair and insulation protection device of the present invention, a second cavity is opened inside the mounting plate on the left side, and one end of the left rotating shaft of the second insulation plate extends to the interior of the second cavity and is fixedly connected to a worm gear, and the interior of the second cavity is rotatably connected to a worm gear meshing with the worm gear.

[0009] In order to improve the protective effect of the thermal insulation protection device, as a preferred coke oven thermal repair thermal insulation protection device of the present invention, the two mounting plates and the side walls opposite to each other of the two vertical plates are fixedly connected with thermal insulation cotton.

[0010] In order to provide power for the rotation of the gear, as a preferred coke oven thermal repair and insulation protection device of the present invention, a first motor is installed on the lower end surface of the base, and the output end of the first motor is fixedly connected to the gear.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] When it is necessary to perform a long-term maintenance on a fixed point in the bottom of the coke oven, the second motor drives the worm, which drives the worm wheel to rotate, and the worm wheel drives the second heat insulation board to rotate 90 degrees, so that the second heat insulation board is placed horizontally to protect the top, and then the two third heat insulation boards are pulled out of the second groove to extend the left and right sides of the heat insulation protection device. The two third heat insulation boards are then used to protect the sides to prevent the heat generated by the inner wall and top of the coke oven from causing discomfort to the workers, thereby performing a long-term maintenance on the bottom of the coke oven.

[0015] When adjusting the width of the thermal insulation protection device, the first motor drives the gear to rotate, and the gear cooperates with the two racks to drive the two mounting plates to move in opposite directions. The two mounting plates respectively drive the left plate and the right plate to move, so that the sliding insulation plate moves out of the first groove, and the width of the first insulation plate and the second insulation plate is increased, so that the thermal insulation protection device effectively blocks the coking oven, thereby improving the protection effect of the thermal insulation protection device.
