Isolation sealing device of viscous fluid conveyor

Abstract

The invention discloses an isolation sealing device of a viscous fluid conveyor, and aims to provide the viscous fluid conveyor with a good isolation sealing performance. The invention provides the technical scheme point that the isolation sealing device of the viscous fluid conveyor comprises a sealing assembly and a bearing box arranged at one end of the sealing assembly, wherein a left shaft neck and a right shaft neck symmetrical to each other are arranged at one end, close to the sealing assembly, of the bearing box; a left sealing component provided with a left shaft neck sealing surfaceand a right sealing component provided with a right shaft neck sealing surface are symmetrically arranged on the sealing assembly; the left shaft neck passes through the left shaft neck sealing surface; the right shaft neck passes through the right shaft neck sealing surface; the sealing assembly and the bearing box form an isolation chamber during installation; one end, far away from the bearingbox, of a sealing seat is a conveying chamber; and a pressure difference is formed between the conveying chamber and the isolation chamber. According to the isolation sealing device of the viscous fluid conveyor provided by the invention, the isolation chamber is arranged between the conveying chamber and the bearing box, and a pressure difference is formed between the isolation chamber and eachspace of the device, so that liquid in each component can be only unidirectionally leaked into the isolation chamber, and an isolation sealing performance is improved.

Description

technical field [0001] The invention relates to the technical field of viscous fluid transport, in particular to an isolation and sealing device for a viscous fluid transporter. Background technique [0002] There is viscous stress in viscous fluid, the fluid is composed of a large number of molecules, and the fluidity of viscous fluid is poor, so it cannot be pressurized and transported by ordinary technologies such as water pumps and hydraulic pumps, especially when the viscous fluid contains particles with large particle sizes. For example, beverages containing fruit pulp, cabinet waste containing sundries, etc., if ordinary technology is used to transport viscous fluids, on the one hand, the particles will be damaged, and on the other hand, the conveying device will be blocked. Therefore, special viscous fluids are often used The conveyor transports the viscous fluid. [0003] The viscous fluid conveyor is driven by a mechanical device. If the seal of the conveyor itsel...
