DETAILED DESCRIPTION

[0017] A preferred embodiment of the present invention will be described below in conjunction with the accompanying drawings to clearly and completely describe the technical solution in a preferred embodiment of the present invention.

[0018] See also Figure 1 and Figure 2 The utility model comprises a sealing groove 1 arranged on both side walls of the trolley and a sealing plate 2 arranged on both side walls of the heating furnace, and the sealing groove 1 and the sealing plate 2 are used in conjunction with each other.

[0019] The sealing groove 1 is movably connected to the side wall of the trolley, a top wheel 11 is provided at the front end of the sealing groove 1, a plurality of rollers 8 are provided at the bottom of the sealing groove 1, a slide rail 9 is provided below the sealing groove 1 along the forward direction of the trolley, the slide rail 9 is fixedly installed on the side wall of the trolley, the roller 8 can slide along the slide rail 9, a plurality of inclined surface blocks 12 are provided on the slide rail 9, the inclined surface blocks 12 are located at the rear side of the roller 8, and the inclined surface of the inclined surface blocks 12 is an arc-shaped curved surface.

[0020] The sealing groove 1 is filled with a refractory material 7 , which is refractory particles or refractory fiber wool. The lower end of the sealing plate 2 can be inserted into the refractory material 7 .

[0021] A plurality of rollers 6 are arranged below the sealing groove 1, and the rollers 6 are vertically fixed on the side wall of the trolley, and the rollers 6 are in contact with the bottom of the sealing groove 1. The rollers 6 support the sealing groove 1 on the one hand, and on the other hand, when the sealing groove 1 moves upward, the rollers 6 roll to guide and reduce the movement resistance of the sealing groove 1.

[0022] The sealing groove 1 is connected to the side wall of the trolley through a plurality of vertically arranged suspension rods 10 , and the suspension rods 10 and the side wall of the trolley, as well as the suspension rods 10 and the sealing groove 1 are all rotatably connected by pin shafts.
