Description

Centrifuge and dissolving discharging method thereof

Technical field

The present invention relates to solid-liquid separation technique, particularly relate to the solid-liquid separation technique of a kind of centrifuge and dissolving discharging thereof.

Background technology

In fields such as chemical industry, medicine, food, mine, metallurgy, light textile, printing and dyeing, well-known, the centrifuge solid-phase material of Separation of Solid and Liquid, filter cake are by manually drawing off or by doctor blade device it being scraped, with the solid form discharging.Be easy with centrifuge with Separation of Solid and Liquid under normal conditions, but, certain difficulty arranged when solid transfer is gone out filter under the working condition that uses inflammable and explosive or high toxicity solvent.And solid-phase material is not final products after the Solid-Liquid Separation, will increase the labour intensity of producing thus with the material that re-uses after the dissolution with solvents in subsequent processing, increases the turnover space, and contaminated environment easily can not satisfy the needs of manufacturing condition usually.

Summary of the invention

At the shortcoming that exists in the above-mentioned prior art, technical problem to be solved by this invention provides a kind of needs that can satisfy manufacturing condition, reduce floor space, improve operating environment, improve the cleanliness factor of surrounding environment, reduce the contaminated possibility of product, the labour intensity that reduces to produce improves the centrifuge of product economy benefit and dissolves discharging method.

In order to solve the problems of the technologies described above, a kind of centrifuge provided by the present invention comprises centrifuge and the feed pipe that is connected centrifuge, cleaning solution feed tube and mother liquor drain pipe; It is characterized in that, also comprise the solvent feed tube and the filter cake lysate drain pipe that connect centrifuge.

In order to solve the problems of the technologies described above, the dissolving discharging method of a kind of centrifuge provided by the present invention, its step is as follows:

A) material to be separated is in feed pipe enters the bowl of rotation at a high speed, and under the effect in the centrifuge field of force, material is realized filtering by filter cloth (filter screen), and liquid phase is discharged through drain pipe, and solid phase then is trapped in the rotary drum;

When B) treating that the internal filtering in rotating drum cake reaches the charge of operational procedure regulation, the stop charging is washed filter cake, simultaneously cleaning solution is leached, reach separation requirement after, close the filtrate (liquid valve;

C) centrifuge low-speed running adds solvent and makes the filter cake dissolving, solution is transported to pump or vacuum makes use, finishes the one action circulation.

Utilize centrifuge provided by the invention and dissolving method, existing centrifuge is carried out architecture advances, the solid material that separation can be obtained dissolves in centrifuge inside, carry out discharging with liquid form then, can under totally enclosed condition, carry out Separation of Solid and Liquid like this, under sealing condition, wash after the Separation of Solid and Liquid, dissolving and discharging.Adopt centrifuge of the present invention can guarantee that Separation of Solid and Liquid, washing filter cakes, dissolving and discharging process carry out under totally enclosed condition, and help keeping the cleaning in production place, reduce the labour intensity of production operation simultaneously.And can carry out continuously or the carrying out washing treatment of repeated multiple times material, thereby this machine is particularly suitable for washing requirement height, the material that needs repeated multiple times to wash again;

Because this centrifuge is operated under air-tight state, thereby this machine is particularly suitable for handling the filtration washing that the existing product of inflammable and explosive, poisonous or hypertoxic danger reaches gourmet food, medicine and the biological products etc. that do not allow pollution; Can make material at the thin layer filter cake or do not have under the filter cake state and handle, thereby the processing speed on the unit are is very high, equipment is little and compact, and floor space is little; Easy and simple to handle, labour intensity is low; Good operational environment, non-environmental-pollution, no material is wandered away and is wasted, to satisfy the needs of various manufacturing conditions.
