Example Embodiment

[0015] The present invention will be further described in detail with reference to the drawings.

[0016] The horizontal spiral unloading sedimentation centrifuge is composed of screw conveyor 5, feed pipe 8, cylindrical drum 11, conical drum 10, drum big end cover 12, drum small end cover 13, big end bearing seat 2, small The end bearing seat 7, the differential 1, the transmission parts, the machine seat 6, the machine housing 3, and so on. The following is divided into several parts:

[0017] (1) The drum part.

[0018] It is composed of a conical drum 10, a cylindrical drum 11, a large drum end cover 12, a small drum end cover 13, etc. There are six liquid outlet holes 14 axially distributed on the large end of the rotating drum, and the liquid level is controlled by a regulating plate 9. In order to meet the needs of different materials and solid phases with different degrees of dryness, this machine adjusts the liquid level size by changing the different overflow radii of th...

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...
