Description
Technical Field
The utility model relates to a material transport technical field, concretely relates to labyrinth sealing device of annular cloth machine.
Background
The annular distributing machine is a material conveying device arranged at the top of a large silo, and is a distributing and conveying device between a storage silo and an incoming material belt conveyor. Incoming materials firstly pass through a belt conveyor on a coal conveying trestle at the top of the silo, then enter an annular material distributor at the top of the silo through a coal dropping pipe, and the material distributor realizes uniform blanking of the inner ring and the outer ring of the silo through forward and reverse rotation. The annular distributing machine mainly comprises a closed belt conveyor, a walking trolley device, a current collector, a rotary supporting device, a sealing cover, an inner ring sealing device, an outer ring sealing device, a ladder railing walking platform, a walking driving device, an electrical control system and the like. The working principle of the annular distributing machine is as follows: after the material falls onto the belt of the distributing machine from the inverted tee joint, if the belt rotates rightwards, the material falls into the inner ring along with the belt; when the belt rotates to the left, the material falls into the outer ring along with the belt. In the working process, because the coal dropping pipe and the feeding port at the top of the guide chute of the closed belt conveyor move relatively, the dust pollution is mainly at the receiving port and the discharging port of the belt and the discharging port when a plow discharger or a scraper discharger is adopted to discharge the coal on the upper layer belt into the distributing machine. Because the fall is large, a large amount of dust is generated when the belt conveyor is separated from coal, and if the belt conveyor is not tightly sealed, firstly, the dust overflows from the interface of the belt conveyor, so that the environment is easily polluted, and the health of people is greatly damaged; secondly, dust is scattered on the rotating part of the belt, so that the abrasion speed of the rotating shaft is accelerated, early damage, oil leakage and the like of a machine are caused, and the dust falls on an electric element, so that the contact of the element is poor, the control is failed and the like. Therefore, in order to prevent environmental pollution and ensure normal operation of equipment, a coal dropping pipe is conventionally inserted into a feeding port of the reversible closed belt conveyor, or a gap between a dropping hopper and the feeding port of the reversible closed belt conveyor is reduced as much as possible, or canvas is fixed on the coal dropping pipe and moves relative to the distributing machine, and covers the coal dropping port of the distributing machine, so that the canvas has a sealing effect. However, these measures are liable to damage due to long-term wear of the canvas or exposure to wind and sunlight.
