[0004] In order to achieve the above purpose, the technical solution of the utility model is implemented as follows:

[0005] A heat treatment furnace sealing device comprises a base, a pushing device and a sealing device, wherein the sealing device comprises a sealing mechanism and a flexible heat-insulating material.

[0006] Among them, one end of the pushing device is fixed on the base, and the other end is connected to the sealing device. The pushing device is fixed on the base and can move back and forth. The sealing mechanism is arranged at the end of the pushing device, and the flexible insulation material is arranged on the periphery of the sealing mechanism.

[0007] More preferably, the sealing device further comprises a lead-out steel pipe, and the lead-out steel pipe is connected to the sealing mechanism.

[0008] More preferably, the sealing device further comprises a sealing flange, which is arranged at one end of the lead-out steel pipe and is used to fasten the lead-out steel pipe, the sealing mechanism and the flexible thermal insulation material.

[0009] More preferably, the flexible thermal insulation material is a fiber blanket.

[0010] More preferably, the sealing mechanism is a castable molded brick. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The drawings constituting part of the present invention are used to provide a further understanding of the present invention. The exemplary embodiments of the present invention and their descriptions are used to explain the present invention and do not constitute an improper limitation on the present invention. In the drawings:

[0014] 100-base, 200-pushing device, 300-sealing device, 310-casting brick, 320-fiber blanket, 330-lead steel pipe, 340-sealing flange, 400-furnace mouth DETAILED DESCRIPTION

[0015] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0016] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0017] A heat treatment furnace sealing device includes a base 100, a push device 200, and a sealing device 300, wherein the sealing device 300 includes a castable brick 310, a fiber blanket 320, a lead-out steel pipe 330, and a sealing flange 340. The base 100 is fixedly connected to the push device 200, and the push device 200 can move back and forth in the axial direction.

[0018] The other end of the pushing device 200 is connected to the sealing device 300 , and specifically connected from left to right are the sealing flange 340 , the lead-out steel pipe 330 , the castable molding brick 310 and the fiber blanket 320 .

[0019] When the furnace door needs to be closed, the pushing device 200 is pushed to the right, and the sealing device 300 moves to the right together with the pushing device 200 until the castable bricks 310 and the fiber blanket 320 of the sealing device 300 enter the furnace mouth 400. At this time, due to the presence of the castable bricks 310 and the fiber blanket 320, the sealing device 300 is in close contact with the furnace mouth 400, which actually plays a good role in heat preservation.

[0020] The fiber blanket 320 is a flexible material, and can play a good buffering role when the sealing device 300 contacts and collides with the furnace opening 400 .

[0021] When the sealing device needs to be opened, the pushing device 200 is withdrawn to the left, and the sealing device 300 is withdrawn from the furnace opening 400 along with the pushing device 200 .

[0022] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
