Abstract

The utility model discloses a methyl massecuite continuous centrifugal machine which is provided with a biose continuous centrifugal machine which comprises components of a conic basket, a driving device, etc., and is additionally provided with an inner screening basket, an air jet system, a receiving device, a steam jet device, etc. When the methyl massecuite continuous centrifugal machine is operated continuously, sugar crystals are discharged from the big end of the conic basket and are subjected to the action of the back draft jetted by the air jet system to slow down. The sugar crystals slowed down are moved to the receiving device, and are received by a nylon rope suspended on the receiving device and fell down; therefore, the sugar crystals are avoided subject to breakage.

Description

Methyl pentose continuous centrifuger

The utility model relates to a kind of continuous centrifugal machine that separates massecuite, and it particularly is applicable to the separation high-grade massecuite.

The continuous centrifugal machine that second, raw massecuite are separated in existing sugar refinery has advantages such as production efficiency height, simple in structure, easy to operate, facility investment and maintenance cost are few.But can't replace with it both at home and abroad at present and separate the discontinuous centrifuge that high-grade massecuite is used, when its major technique key is that sugar crystal is discharged from boring the big end of basket, penetrate facing to shell with very high speed, collision outer cover metal plate, cause crystal to wreck, cause sugar crystal uniform particles degree not reach standard-required.

Task of the present utility model is that a kind of improved methose continuous centrifugal machine will be provided, it can make the sugar crystal of separating, the uniform particles degree that not only guarantees sugar crystal reaches standard-required, and guarantees the colour of sugar crystal, and every indexs such as moisture content and ashes also can satisfy standard-required.

Task of the present utility model is finished as follows: the methose continuous centrifugal machine is formed by advancing cream pipe, divider, interior basket, awl basket, washing device, spray tube, steam sparging device, air jet system, receiving trap, transmission mechanism, shell and support etc.

Air jet system of the present utility model is formed by being installed in the big end rotary packing ring of awl basket plenum chamber, air feeder and nozzle ring on every side.

Air feeder in the continuous centrifugal machine is made up of gas blower or air compressor.

Receiving trap in the continuous centrifugal machine is vertically fixed on the whizzer cover plate of outer casing by nylon rope or rubber rope or the rope made of hemp to be formed

The working process of above-mentioned continuous centrifugal machine is as follows:

1, massecuite adds from top, enters divider through advancing the cream pipe, when massecuite is flowed through the annular water pipe at cream tube inlet place into, feeds a spot of pressure water of annular water pipe from the outside and through managing inboard aperture massecuite is sprayed, with the dilution massecuite.When massecuite flow to into cream pipe bottom tapered sleeve, be subjected to feeding taper chuck hot steam by the outside, the uniform aperture in the taper chuck on the jacket wall sprays heat temperature raising to massecuite, reduces the viscosity of massecuite, improves its flowability, and is close in order to dividing.In the divider of rotation, massecuite is by action of centrifugal force, distributes equably by the hole around the divider to enter interior basket.

2, massecuite is separated in the interior basket of rotation, molasses are under action of centrifugal force, screen cloth and brass net enter interlayer through row's honey hole of interior basket inwall in passing, discharge by row's honey tube then, sugar crystal is then stopped by interior screen cloth, and under the effect of centrifugal force and gravity, move downward to awl basket bottom.

3, enter the sugar crystal of awl basket bottom from interior basket, be subjected to supplying with and cleaning along interior sieve outer flow to the washing water of boring the basket bottom by exterior line.The sugar crystal that process is cleaned is under action of centrifugal force, and washing honey and sugar crystal move upward along awl basket wall.In moving process, washing honey passes screen cloth and the row honey hole of brass net on awl basket wall and is thrown to and connects in the sweet case.Discharge along row's honey tube, stay sugar crystal on the basket wall under action of centrifugal force, continuation moves upward along the basket wall, in moving process, be subjected to the baking of the hot steam that vapour pipe penetrates and desiccation, when the exsiccant crystal moved to the big end margin of awl basket, just the tangential direction along awl basket outside diameter flew out at a high speed.

4, when sugar crystal constantly from awl basket big end when crystal direction of motion is discharged, the air jet system that is subjected to having by oneself specified pressure sprays the effect of rightabout airstream and slows down.

5, spray tube is sprayed facing to firm crystal of discharging from the awl basket by the aperture on the ring pipe by the pressure steam of outside supply, and crystal is played the assisted deceleration effect and further dries crystal.

6, when the sugar crystal that slows down through air continues outwards motion, be received device and receive, and fall into space between shell and the plenum chamber automatically by gravity, discharge from the whizzer bottom.

The utility model is simple in structure, and the production efficiency height is easy to operate, the sugar crystal uniform particles degree of production, and item indexs such as colour, moisture content and ashes reach standard-required.Be applicable to that cane sugar factory separates the continuous centrifugal machine of high-grade massecuite.
