　　Sludge treatment centrifugal dewatering machine Ruichen brand sludge solidification dewatering centrifuge

　　Centrifugal desilting machine is a horizontal spiral discharge and continuous operation settling equipment. Its working principle is as follows: the drum and the screw rotate at a certain differential speed and high speed in the same direction, and the material is continuously introduced into the inner cylinder of the conveying screw through the feeding pipe. After acceleration, it enters the drum, and under the action of the centrifugal force field, heavier solid substances deposit on the drum wall to form a sediment layer. The feeding spiral continuously pushes the deposited solid phase to the cone end of the drum and discharges it outside the machine through the slag discharge outlet. The lighter liquid phase forms an inner liquid ring, which continuously overflows from the large end overflow port of the drum and is discharged outside the machine through the discharge port. This machine can continuously feed, separate, wash, and discharge materials at full speed. It has the characteristics of compact structure, continuous operation, smooth operation, strong adaptability, high production capacity, and convenient maintenance.

　　Main components of Ruichen brand sludge solidification dewatering centrifuge for sludge treatment centrifugal dewatering machine

　　1. Drum drum

　　It is a cylindrical cone cylindrical rotor composed of a cone and a cylinder, designed to achieve better separation performance. When the drum rotates at high speed, it drives the slurry to rotate together. Under the action of centrifugal force, heavier solid particles will be separated from the liquid. The cylindrical part of the drum is designed to facilitate the clarification of the filtrate (centrifugal separation), while the conical part is beneficial for the dehydration of solid materials.

　　Spiral feeder

　　The spiral unloader accelerates the feeding of slurry and pushes the material deposited on the inner wall of the drum to the solid discharge end of the centrifuge. The two bearings supporting the spiral unloader are pressed into the two drum covers, and the bearings are separated from the processed material by the skeleton oil seal assembly assembled on the spiral core shaft. The spiral unloader is composed of a spiral core shaft, spiral blades, and two connecting plates that support the rotation of the spiral unloader. The spiral core shaft has a feeding chamber and several feeding holes. The feeding end journal is a hollow structure, and the feeding tube leads to the feeding chamber through the hollow journal. The differential end journal is a spline structure and is connected to the differential output spline

　　3. Bearing

　　The main bearings are all rolling bearings that support the entire rotor assembly. These bearings are assembled into bearing seat components, which are positioned by centering pins during installation and then fastened to the centrifuge base

　　The bearing seat components are made of cast iron material, and the feed end bearing is a fixed radial ball bearing. The drum is limited in axial movement by it, and the differential end bearing is a detachable roller bearing, which allows axial movement due to thermal expansion or contraction of the centrifuge.

　　4. Differential mechanism

　　The differential drives the spiral unloader and rotates it at a constant speed relative to the outer drum. The reduction ratio of the differential and the input shaft speed of the outer drum and differential determine the speed difference between the outer drum and the spiral unloader; Except for replacing lubricants, maintenance and repair of the differential can only be carried out by personnel trained by our factory. The transmission ratio of the gearbox has been selected, and the spiral unloader has obtained a speed that can meet the requirements of solid discharge volume and separation efficiency.

　　5. Cover shell

　　The casing consists of an upper casing and a lower casing; There is a sealing gasket on the mating surface of the upper and lower covers to prevent leakage of the machine body. The sealing gasket is made of nitrile rubber or fluororubber (depending on the material). The casing is like a protective cover that completely seals the rotating parts, and of course, the casing also plays a role in discharging solid particles from the rotating parts and containing and guiding them. The casing is divided into a solid slag storage chamber and a liquid storage chamber, with a cylindrical outlet with a diameter of 80mm and a rectangular slag outlet at the bottom of the casing.
