Feed system of top suspension centrifuge

Abstract

The invention discloses a feed system of a top suspension centrifuge. The system mainly comprises a feed tank and a massecuite distribution machine, wherein one end of the feed tank is connected with a massecuite distributor through a feed valve, and the other end is connected with a massecuite distribution mechanism through a discharge valve; and distributing openings towards a massecuite distribution tray are uniformly arranged on the massecuite distribution mechanism, or distributing tubes are uniformly guided into a sieve basket in paths. In the invention, the feed tank and the massecuitedistribution mechanism are added between the traditional massecuite distributor and the centrifuge, the problems of nonuniform feed distribution, incapability of accurately determining the practical production capacity and the constantly changing feed speed in the traditional feed system are solved, thereby ensuring the production safety and enhancing the production efficiency.

Description

technical field [0001] The invention relates to a top-suspension centrifuge, in particular to a top-suspension centrifuge feeding system used in the sugar industry. Background technique [0002] Nowadays, the top suspension centrifuge in the sugar industry has developed from a small gravity discharge centrifuge of 0.5 tons / sieve in the past to a large scraper discharge centrifuge of 1.3 to 2.5 tons / sieve. A series of problems have followed, as follows : [0003] 1. Uneven feeding distribution [0004] The centrifuge handles a large amount of massecuite, and the rotational inertia of the operation is also very large, which requires that the material be distributed very evenly in the sieve basket during the operation to keep the centrifuge running smoothly and exert its best performance. Most of the existing top-suspended centrifuge feeding systems are massecuite distributing tanks directly connected to the centrifuge cover plate by the pipeline through the valve, and a drip...

AI Technical Summary

Problems solved by technology

However, the purity and brix of massecuite in actual production vary with the process conditions. When the massecuite is thin or pure, it has good fluidity, and it is directly guided by the sealing plate of the drip tray valve to the massecuite distribution plate in the same direction. Blocked by the massecuite distribution plate, the massecuite is splashed and scattered on the inner surface of the sieve basket. At this time, the massecuite distribution plate does not play a role in uniform distribution, and cannot ensure that the massecuite is evenly distributed inside the sieve basket; when the massecuite is thick or the purity is low The fluidity is very poor, the massecuite from the distribution tank cannot touch the massecuite distribution plate after passing through the valve and the sealing plate of the drip plate valve, but slowly falls to the bottom of the sieve basket, although the sugar at the bottom of the sieve basket is under a certain centrifugal force Paste tends to climb, but does not form an even distribution inside the basket

When the material distribution inside the sieve basket is not uniform, the sieve basket will swing, vibrate, or even "shot" during the operation of the centrifuge, which will seriously affect the life of the equipment and production safety.

[0005] 2. The actual production capacity cannot be accurately measured

[0008] The feeding of the existing top-hung centrifuge is to use the massecuite liquid level in the massecuite distribution tank to press it into the centrifuge by its own weight. Due to manual operation factors, the liquid level of the massecuite is sometimes high and sometimes low, and the massecuite enters the centrifuge. The speed is also different, which affects the uniformity of the centrifuge and the operating cycle, thereby affecting the production efficiency
