the traction mechanism comprises a bracket, a support, a handle, an opening and closing handle and a traction rope, the bracket is arranged at the end of the wall of the heat storage chamber, the support is convenient to fix, the support is arranged in the middle of the bracket, the handle is fixedly arranged on the support, the opening and closing handle is arranged on the handle, one end of the traction rope is fixed on the opening and closing handle, and the other end of the traction rope penetrates through the support to be connected with a second connecting rod of the parallelogram link mechanism; when the opening and closing handle is held, the second link rod is driven to move towards one side close to the traction mechanism, the included angle of the two first link rods is synchronously increased, so that the parallelogram link rod mechanism is in an expanded state, the skirt edge abuts against the wall surface of the regenerator, and otherwise, the parallelogram link rod mechanism is in a contracted state; the holding end of the handle is also provided with a limiting ring, when the opening and closing handle is held, the opening and closing handle is sleeved by the limiting ring, and the expansion state can be locked by the parallelogram link mechanism.
8. The coke oven regenerator checker brick construction ash isolation apparatus of claim 7, wherein a torsion spring is provided at a connection of the first link and the second cover plate through a pin, and when the first link is not pulled by the pulling mechanism, the second left cover plate and the second right cover plate are moved closer to each other toward the middle by the torsion spring.
9. The coke oven regenerator checker brick construction ash isolation device of claim 7, wherein a plurality of second cover layers are provided along the length of the regenerator, and adjacent cover layers are connected in series through a connector, so that the second cover layers can be recovered from the side of the furnace mouth uniformly when the engineering is finished; the parallelogram link mechanisms of the plurality of second covering layers are connected into a linkage whole through the second links and are driven by the traction mechanism in a unified mode.
10. The coke oven regenerator checker brick construction ash isolation device of claim 1, further comprising a slag removal port provided at the side of the fire door and at the coke side of the coke oven regenerator, wherein the slag removal port at one side is used for air intake, and ash is blown into the slag removal port at the other side for cloth bag dust removal.
