Description

With the anti-supercentrifuge for spilling block

Technical field

The utility model is related to centrifugal device field, more particularly to the anti-supercentrifuge for spilling block.

Background technology

Supercentrifuge is mainly used in separating the solid particle in suspension and liquid, or by two kinds of density in emulsion Difference, but immiscible liquid is separated.The cardinal principle of centrifuge be exactly using rotor at a high speed rotation produce it is powerful from The sinking speed of particle in mental and physical efforts, accelerating liquid, separates the material of different sedimentation coefficients and buoyant density in sample.

When carrying out high speed centrifugation operation using supercentrifuge, it is sometimes desirable to which the sample containing low boiling point solvent is carried out Operation, such as ether（The boiling point of ether is about 35 DEG C）, the sample containing ether under low-temperature condition is put into high speed at room temperature In centrifuge, when rotating at a high speed, the ether temperature rise in centrifuge tube, pressure increase promotes the lid of centrifuge tube to collapse out, centrifuged Sample in pipe will splash on the cover plate of supercentrifuge, the internal environment of pollution cover plate and supercentrifuge, cleaning is not Just, it would therefore be desirable to design a kind of supercentrifuge for having and preventing spilling block, make to enter the sample containing low boiling point solvent Row operation when, sample will not splash pollution cover plate and supercentrifuge internal environment.

Utility model content

The utility model has the anti-high speed for spilling block to solve weak point of the prior art there is provided a kind of Centrifuge, when making to operate the sample containing low boiling point solvent, sample will not splash pollution cover plate and supercentrifuge Internal environment.

In order to solve the above technical problems, the utility model is adopted the following technical scheme that：With the anti-high speed for spilling block from Scheming, including body, rotor and the cover plate that is articulated with the top of body, the inside of the body are provided with centrifugal chamber, the centrifugal chamber Upper end open at body be provided with sealing ring, the inside of the body is provided with rotary electric machine, the inside of the centrifugal chamber Heart position is provided with the rotating shaft being connected with rotary electric machine, and the rotor is set in rotating shaft, and the rotor is up-small and down-big Truncated cone-shaped, the rotor is evenly distributed several symmetrical centrifugal holes for being used to place centrifuge tube two-by-two, each centrifugal hole Upper end is open in the upper surface of rotor, the center line of each centrifugal hole each parallel to rotor bus, the rotor it is outer Two symmetrical fixed ears are highly fixedly connected with same level on side surface, the rotor also includes being set on rotor Block, the block is the hollow round table shape matched with rotor, and the openend of block inwall is arranged with two and fixed ear The vertical slot that width dimensions match, vertical slot is communicated with circular trough upwards inside block, and the vertical section of vertical slot and circular trough is in T Type, the height of circular trough is more than the handle being fixedly connected with the top of the thickness of fixed ear, the block for taking.

The front-end case of the body is provided with the control panel for being used for controlling rotary electric machine rotating speed, the inside of the body Provided with the electric control gear being connected with rotary electric machine, the control panel is connected with electric control gear by circuit.

The quantity of uniform centrifugal hole symmetrical two-by-two is six around the rotor.

Using above-mentioned technical proposal, the utility model has advantages below：

The sealing ring set on body can strengthen sealing of the present utility model, laboratory sample will not because splash etc. other Reason pollutes the external environment condition of supercentrifuge, can avoid some poisonous samples（Such as liquefied ammonia, ether）Dirt to external world Dye, improves the security of supercentrifuge.

When carrying out high speed centrifugation operation to the sample containing low boiling point solvent using the utility model, if in centrifuge tube Low boiling point solvent because temperature raise, pressure increase and promote the lid of centrifuge tube to collapse out, the sample in centrifuge tube can be by block Block, will not splash on cover plate or splash is into centrifugal chamber, reducing the pollution that sample is caused to supercentrifuge, also, When clearing up pollutant, block only need to be cleared up, without cover plate and centrifugal chamber are cleared up simultaneously, so as to reduce the work of cleaning Amount.
