Horizontal decanter solid-bowl centrifuge

Abstract

The invention relates to a rotary solid bowl centrifuge with a helical conveyor, in particular to a horizontal decanter solid-bowl centrifuge. A flange plate is provided with a scraper, and is connected to the auger conveyor through a screw; a liquid limit ring is arranged on the end part of a helical large-end cylinder, has a sheet ring shape, and has the outer diameter smaller than the inner diameter of a cylindrical bowl; the middle of the liquid limit ring is provided with a through hole sleeved on the helical large-end cylinder and the liquid limit ring is fixedly arranged on the helical large-end cylinder; and an adjusting plate is fixedly arranged on a large-end cover of the bowl, and is fixedly connected with a blocking plate. The horizontal decanter solid-bowl centrifuge has the characteristics of compact structure, convenience for installation, simple operation and maintenance, good use effect and the like; the scraper can effectively scrape solid-phase particle accumulation, has a good effect, and protects the safety of a seal ring and a bearing; the liquid limit ring contributes to settling fine solid-phase particles to greatly improve the separating performance of the machine; and the adjusting plate with the blocking plate effectively prevents flowing liquid from splashing to a labyrinth seal ring, and the liquid is prevented from being leaked to protect environment. The technology is applied to the horizontal decanter solid-bowl centrifuge.

Description

technical field [0001] The invention relates to a rotary drum centrifuge with a screw conveyor, in particular to a horizontal screw discharge sedimentation centrifuge. technical background [0002] The horizontal screw discharge sedimentation centrifuge utilizes the principle of obtaining different sedimentation velocities in the centrifugal force field by using the light, heavy liquid and solid phases with different densities and immiscibility in the mixed liquid to achieve separation and stratification or make the solid in the liquid The purpose of particle settling. This machine can operate automatically and continuously. It is widely used in chemical industry, light industry, food, mineral processing and other industrial sectors. It is also an ideal equipment in environmental protection projects. It is suitable for volume concentration ≤ 40%, solid phase density is greater than liquid phase density, and has a certain Separation of liquid suspensions. After the solid ph...

Problems solved by technology

In the existing centrifuges of this type, when the clear liquid is discharged from the big end of the drum, it directly washes the casing, and the liquid is easy to splash and leak out of the casing from the gap between the rotating shaft and the labyrinth sealing ring of the casing, causing pollution to the environment
