Abstract

The invention relates to a centrifuge for the separation of suspensions, for example sugar refineries. The purpose of the invention is to increase centrifuge productivity and reliability. In the central part of the rotor 2 of the centrifuge there is a sieve 7, made in the form of a truncated cone, and the rotor drive shaft 1 is made empty. In its upper part, a shut-off valve 8 is located inside, and a hollow rod 9 with a gate valve 10 is installed in the supply pipe 4, which serves to supply steam and interact with the shut-off valve 8. Such a centrifuge will increase its performance by removing lumps of solids stopping the centrifuge and increasing its reliability by separating lumps of solids even before filtering blades 3. 2 sludge.

The aim of the invention is to increase the reliability and 11th: centrifugal fugacity.

FIG. 1 izob) right centrifuge, longitudinal section; in fig. 2 — node I in FIG. one.

The centrifuge contains a rotor 2 mounted on the drive shaft 1 with filtering blades 3, a threading tube 4, and a suspension distribution device consisting of a series of cones 5 mounted one above another.

It is filtered by a filter blade m 3 and then enters the filtrate collector. During the filtration on the sieve 7, lumps of solids accumulate in the lower part of the rotor 2. Periodically, without stopping the centrifuge, the shut-off valve 8 is opened with the aid of the brush 9 with the knob 10 and the central part of the rotor 2 is blown with steam (water) to remove the lumps of solids that leave from the centrifuge through the hollow shaft 1. Cara (water) is fed through pipe 13 supplied to the hollow rod 9.

This embodiment of the centrifuge allows to increase its productivity by removing lumps of solids without

central holes 6. The diameter of the hole - stopping the centrifuge and increasing its reliability 6 each lined plate 5 prelnity by determining the lumps hardens the diameter of the hole 6 of each lower plate 5. The diameter of the largest hole 6 does not exceed the diameter of the feeding pipe 4. In the central 2p of the rotor 2, a sieve of 7, having the shape of a truncated cone. The rotor I shaft of the rotor 2 is hollow, and a shut-off valve 8 is installed at its top. A hollow pin 9 is installed in the feed pipe 4 to supply steam and interact with the check valve 8. The rod 9 has rolls 10 at the end. The pipe 4 is fitted with a guide 11 having a threaded connection with the rod 9. The rod 9 is pressed down to the shut-off valve 8 with the bottom part. The pulley 12 is mounted on the shaft 1.

The centrifuge works as follows.

The original slurry feed pipe 4 enters the central part of the rotor 2. The passage through the sieve 7, the filtered mass is cleaned of lumps of solids and evenly distributed substances with the help of distribution cone-shaped plates 5 before the filter blades.
