Example Embodiment

[0017] The labyrinth-type choke device of the present invention comprises a fixed choke ring 1 connected with the thermal insulation door panel and a rotating choke ring 2 connected with the shaft head of the guide roller.

[0018] The fixed choke ring 1 of the present invention is composed of a fixed inner ring and a fixed outer ring, and is connected and fixed with a bolt to the inner side of the thermal insulation door panel; a certain distance is formed between the fixed inner ring and the fixed outer ring.

[0019] The rotating choke ring 2 of the present invention is composed of a rotating inner ring, a rotating outer ring and a connecting sleeve. The connecting sleeve is sleeved on the shaft head of the guide roller, and is fixed with the shaft head of the guide roller with a set screw to ensure that the rotating choke ring 2 and The guide roller shaft head rotates together; a certain distance is formed between the rotating inner ring and the rotating outer ring.

Abstract

Labyrinth wind blocking device for printing and dyeing industry. The utility model relates to a labyrinth-type wind-blocking device for preventing hot air from radiating out of a drying room in the printing and dyeing industry. It includes the fixed wind resistance ring set on the inner side of the insulation board of the drying room and the rotating wind resistance ring set on the guide roller and rotating with the guide roller. Both the fixed wind resistance ring and the rotating wind resistance ring are set by several horizontal lines of different sizes. It consists of a fixed barrel ring retaining ring with a fixed wind blocking ring and a rotating barrel retaining ring with a rotating wind blocking ring. The stroke is arranged in a labyrinthine channel with multiple turns. The invention provides a labyrinth-type wind blocking device with low cost, good leakage blocking effect, convenient operation and durability.

Description

technical field [0001] The invention relates to a sealing device, in particular to a labyrinth-type air blocking device for preventing hot air from radiating out of a drying room in the printing and dyeing industry. Background technique [0002] In the textile, printing and dyeing industry, there are several rotating guide rollers in the drying room of the hot air drying equipment, and the working temperature in the drying room is between 120°C and 220°C, and the guide roller shafts must wear The thermal insulation door panel protrudes out of the drying room to install supporting bearings to ensure reliable lubrication and normal operation of the bearings. Because the insulation door panel is fixed, and the guide roller shaft is rotating, so the guide roller shaft must have a gap with the insulation door panel hole in order to ensure the flexible operation of the guide roller when passing through the insulation door panel. If effective leak-proof measures are not taken, the...
