Embodiment Construction

[0009] A split type solid dust mechanical shaft seal system, such as figure 1 As shown, it includes a shaft seal gland 2 installed on the machine box, a PTFE gasket 18 is arranged between the gland 2 and the sealing surface of the box, and a multi-layer sealing contact with the rotating shaft is arranged on the inner side of the center hole of the gland. Lip seal ring 1 is used to slow down the dust leakage. After a period of operation, the lip seal will wear out quickly when there is no liquid lubrication. After wear, there will be a small gap between the lip seal and the shaft. The lip seal belongs to Multi-layer, can play the effect of labyrinth seal at the same time.

[0010] The outer side of the central hole of the gland is in the shape of a stepped hole, and a sealing stationary ring 4 fixedly connected to the gland is set on the rotating shaft in the stepped hole. The outer peripheral surface of the stationary ring 4 has an annular shoulder. An O-ring 17 is arranged b...

Abstract

The invention discloses a split type solid dust mechanical seal system. The inner side of a pressure cover center hole is provided with a multi-layer lip sealing ring, a rotating shaft in the pressure cover center hole is sleeved with a sealing static ring, a rotating shaft at the outer side of the static ring is sequentially sleeved with a rotating ring, a transmission seat and a fixing ring seat which are connected respectively through pins and rotate synchronously, the fixing ring seat and the rotating shaft are fixedly connected together, the inner peripheral wall of the fixing ring seat is provided with an O-shaped sealing ring being in contact with the rotating shaft; an annular groove is arranged in the fixing ring seat, the transmission seat is matched and sleeved in the annular groove, an O-shaped sealing is arranged between the inner end face of the fixing ring seat and an annular stop shoulder at the outer peripheral wall of the rotating ring, and the fixing ring seat and the rotating ring are matched and sleeved in a fixing pressure cover; and the fixing ring seat, the transmission seat, the rotating ring, the static ring and the fixing pressure cover are formed by twohalf bodies respectively, a lubricating grease wear-reducing structure is arranged on the end face of the static ring which is in contact with the rotating ring, and a compensation spring is arrangedbetween the transmission seat and the fixing ring seat.

Description

technical field [0001] The invention relates to a shaft sealing system for dust machinery, in particular to a split type solid dust mechanical shaft sealing system. Background technique [0002] Packing seals are mostly used for dusty equipment, and seal failures and damages are frequent, especially for dry equipment, where seal failures are particularly prominent. The main reason for many equipment failures is that the packing seal is hardened, and there is no compensation force, which is very easy to damage the shaft or sleeve. Contents of the invention [0003] The purpose of the present invention is to provide a split type solid dust mechanical shaft seal system, which has a simple structure, is easy to manufacture and install, can improve the sealing effect of dust conveying equipment, and prolong the continuous start-up time of the equipment. [0004] The purpose of the present invention is achieved in this way: a split type solid dust mechanical shaft seal system, ...
