Description

A kind of animal and veterinary laboratory hand held centrifugal device

Technical field

The utility model is related to feed separation equipment technical field, and in particular to a kind of animal and veterinary laboratory hand held from Center device.

Background technology

Centrifuge is to utilize centrifugal force, the machine of separation liquid and each component in solid particle or the mixture of liquid and liquid Tool.Centrifuge is mainly used in separating the solid particle in suspension and liquid；Or by two kinds of density differences in emulsion, and mutually Immiscible liquid separates (such as cream is isolated from milk)；It can also be used for excluding the liquid in wet solid, such as with Washing machine dries wet clothes；The admixture of gas of the also separable different densities of special hypervelocity channel separator；It is close using difference Degree or granularity solid particle in a liquid sinking speed difference the characteristics of, some sedimentation centrifuges can also be to solid particle by close Degree or granularity are classified.

Centrifuge is widely used in the departments such as chemical industry, oil, food, pharmacy, ore dressing, coal, water process and ship.Industry Structure and separation requirement are pressed with centrifuge, filtering centrifuge, sedimentation centrifuge and the class of seperator three can be divided into.Centrifuge has one The cylinder rotated at a high speed around this body axis, referred to as rotary drum, are generally driven by motor.Suspension (or emulsion) adds rotary drum Afterwards, driven rapidly and rotated at the same speed with rotary drum, each component separates under the action of the centrifugal force, and discharges respectively.Generally, rotary drum rotating speed Higher, separating effect is also better.

There are two kinds of centrifugal filtration and centrifugal sedimentation by the action principle of centrifugal separator.Centrifugal filtration be make suspension from Mental and physical efforts caused centrifugal pressure off field, is acted on filter medium, liquid is turned into filtrate by filter medium, and solid particle Filter media surface is trapped within, Gu so as to realize liquid -- separation；Centrifugal sedimentation is to utilize suspension (or emulsion) density not The principle of same each component rapid sedimentation layering in centrifugal force field, Gu realize liquid -- (or liquid -- liquid) separation.It is also a kind of real The seperator of analysis is tested, can carry out liquid clarification and solid particle enrichment, or liquid-liquid separation, this kind of seperator has normal pressure, true The different structure type operated under empty, freezing conditions.The important indicator for weighing centrifugal separator separating property is separation factor.It Be separated material centrifugal force suffered in rotary drum and the ratio of its gravity are represented, separation factor is bigger, is generally separated also more fast Speed, separating effect are better.The separation factor of industrial centrifugal separator is generally 100~20000, point for the channel separator that exceeds the speed limit 62000 are may be up to from factor, analysis is up to 610000 with the separation factor of hypervelocity seperator.Determine centrifugal separator processing energy Another factor of power is the work area of rotary drum, and the big disposal ability of work area is also big.

Select centrifuge must according to the size and concentration of solid particle in suspension (or emulsion), solid and liquid (or Two kinds of liquid) density contrast, liquid viscosity, the characteristic of filter residue (or sediment), and requirement etc. of separation carries out comprehensive analysis, full Which kind of centrifugal separator requirement of the foot to filter residue (sediment) water capacity and filtrate (separating liquid) clarity, initial option use. Then by treating capacity and the automation requirement to operation, the type and specification of centrifuge is determined, is most verified afterwards through actual tests.It is logical Often, for containing suspension of the granularity more than 0.01 mm granules, filtering centrifuge can be selected；It is tiny for particle in suspension Or compressible deformation, then preferably select sedimentation centrifuge；For suspension containing amount of solid is low, particle is small and to liquid clarity It is required that when high, seperator should be selected.

Centrifuge is a kind of biological extraction instrument, the clear liquid in biological extraction liquid and solid matter to be separated. The test tube for filling extract solution is placed in the groove of bowl during use, rotary drum rotates at a high speed under the drive of motor.From And the solid deposits in extract solution are got off.It is symmetrical arranged generally in bowl centered on rotary shaft multiple recessed Groove, for being separated to the extract solution of multiple test tubes simultaneously.The treating capacity of extract solution can so be greatly improved.But in reality In the application of border, usually there is the situation that the groove of rotary drum does not use all, a groove is used only when being provided with.It can so cause Rotary drum distribution of weight is unbalanced, so as to damage motor., in operation can be relative in used groove in order to solve this problem A test tube is placed in the position of axisymmetry again, and the water of equivalent is put in the inside, to cause rotary drum center of gravity to be distributed in rotation as far as possible On axle.But this method is more troublesome, and can not still solve the problems, such as deviation of gravity center rotary shaft.

There is a kind of vertical type full automatic conveyer centrifugal at present, be the master of fine chemistry industry and pharmaceutical industry separation of solid and liquid process Processing apparatus is wanted, has the advantages that production efficiency height, wide adaptation range, automaticity are high.Its action principle is to utilize rotary drum Strong effect of centrifugal force caused by rotation at a high speed, the solid phase of the material to be separated added in rotary drum is trapped on drum inner wall, Liquid phase by the filter screen hole that is fixed on rotatory drum wall, through rotatory drum wall on the aperture that is provided with, throw away rotary drum；Separation process terminates Afterwards, rotary drum is down to the slow-speed of revolution, strikes off from rotatory drum wall solid formation by the rotation and lifting doctor blade device on cover, passes through The tapping channel discharge centrifuge body of centrifuge bottom completes the course of work.However, the thing on rotatory drum wall is struck off in above-mentioned scraper It is required between scraper and filter screen to retain certain safe distance (generally 5-10mm or so) during material, to prevent scraper from scraping Bad filter screen；This safe distance causes to form remaining cake layer on filter screen, and the presence of this remaining cake layer not only results in batch Between pollution, and filter efficiency can be reduced.Traditional mode of production be centrifuge shutdown after, it is manually clear by operating personnel Remove, exploitation operation, not only labor intensity is big, low production efficiency, and the discharge of inflammable, explosive, poisonous gas and operating of contacts personnel； Another is nitrogen blowback residual filter cake, consumes a large amount of nitrogen and the discharge of poisonous or flammable explosive gas.And due to chemical industry Product with pharmaceutical manufacturing is mostly poisonous and harmful substance, and the body of operating personnel can be damaged.
