Sealing structure of centrifugal machine for silicon carbide separation

Abstract

The invention relates to an improvement structure of a centrifugal machine component. A leakproof structure of a centrifugal machine for silicon carbide separation is characterized in that the outer part of an external connection ring (4) is provided with a locating slot, and a framework seal ring (12) which has a lip facing the left side is arranged in the locating slot; a screwed hole is formed in an external connection pipe (6) of a drum, and a bolt (13) is screwed into the screwed hole, so a grease chamber (14) is formed between the lower end face of the bolt (13) and the end faces of a conveyor connection ring (5) and a check ring (7), and is fully filled with grease; and a scraper (11) which has an opening facing the left side is arranged at the end of the auger conveyor (2). By the leakproof structure, the service life of a bearing is prolonged, meanwhile, the part dismantling and changing costs and working hour cost are also avoided and lowered, loss and waste which are caused by delayed operation progress are influenced, and the leakproof structure has a great practical application meaning.

Description

technical field [0001] The invention relates to an improved structure of a centrifuge mechanism part, in particular to a sealing bearing protection structure of a centrifuge for separating silicon carbide. Background technique [0002] As is known, a horizontal screw centrifuge is a separation machine that relies on the density difference between the solid and liquid phases, and under the action of centrifugal force, speeds up the settling velocity of solid phase particles to achieve solid-liquid separation. With the needs of modern environmental protection and the development of three wastes treatment, the requirements for industrial wastewater and sludge dehydration treatment are gradually increasing. Due to the unique characteristics of continuous operation, large processing capacity and strong adaptability, decanter centrifuges have developed very rapidly. [0003] In the decanter centrifuge, after the sludge is sent into the drum from the sludge feed pipe, it is immedi...

Problems solved by technology

[0007] The specific defect of the prior art is that the silicon carbide transported by the screw conveyor is a material with high wear resistance. When the centrifuge separates its raw liquid, the screw and the rotor At the joint of the drum, silicon carbide powder particles can easily enter the gap between the outer ring and the conveyor ring through the gap, and then enter the end face gap between the conveyor ring and the outer ring, and then pass through the inner ring and the outer ring. The gap between the retaining rings enters the inside of the bearing, causing the bearing to wear out quickly

The cost of disassembly and replacement parts and man-hours will be a great loss and waste if it affects the delayed operation progress, and urgently needs to be changed and improved.
