Air-tight sealing device of head of belt conveyor

Abstract

The invention discloses an air-tight sealing device of a head of a belt conveyor applied to the field of belt conveying. The device structurally comprises a fixing plate, a sealing pipe, a sealing gasket and a sealing cover, wherein the fixing plate, the sealing pipe, the sealing gasket and the sealing cover are sequentially arranged; the end face of one end of the sealing pipe is coaxially weldedto the side face of the fixing plate, the sealing gasket is sleeved with the other end of the sealing pipe, the outer surface of the sealing gasket and the inner surface of the sealing pipe are welded and positioned, the inner surface of the sealing gasket is provided with an inner ring groove facing the sealing cover, one end of the sealing cover is internally sleeved with the inner ring groove,the space among the sealing cover, the sealing gasket and a shaft is filled with sealing filler in the inner ring groove, a gas ring cavity is defined by the fixing plate, the sealing pipe, the sealing gasket, the sealing filler and the shaft, and one side of the sealing pipe is provided with an air inlet. According to the device, dust is prevented from passing through the connecting gap betweenthe shaft and the shell through the gas pressure, so that the sealing operation to the connecting gap is realized, the auxiliary circumferential positioning for the shaft can be realized through the flow of circumferential air pressure, the equipment connecting quality is further improved, the connecting relative friction force is reduced, and the matched driving effect is improved.

Description

technical field [0001] The invention relates to a belt conveyor head air sealing device used in the field of belt conveyor material conveyance. Background technique [0002] Belt conveyors transport workpieces for important materials, especially large complete sets of equipment. During the application process, the end of the shaft of the head of the belt conveyor needs to be positioned and extended out of the corresponding head shell, and then the end positioning operation is realized by using the bearing seats on both sides of the head shell, and one end is connected with the drive The device is connected to realize the stable operation of the rotary drive. However, during the operation, the dust inside the equipment will overflow from the connection gap between the head shaft and the equipment casing, which will have a negative impact on the quality of the working environment of the belt conveyor. At the same time, the spilled dust will partially stick to the connection ...
