Description

A centrifuge rotor device

technical field

The utility model relates to a centrifuge, in particular to a centrifuge rotor device.

Background technique

The centrifuge is mainly used to separate the solid particles in the suspension from the liquid; or to separate two liquids with different densities and immiscible liquids in the emulsion (such as separating cream from milk); it can also be used Remove liquid from wet solids, such as drying wet clothes with a washing machine; special ultra-speed tube separators can also separate gas mixtures of different densities, such as enriching and separating gaseous uranium hexafluoride; using solid particles of different densities or particle sizes in Due to the different sedimentation speeds in liquids, some decanter centrifuges can also classify solid particles according to density or particle size. Centrifugal separators are widely used in chemical industry, petroleum, food, pharmaceuticals, mineral processing, coal, water treatment and ships and other departments. The current centrifuges are fixed with grooves on the rotor, insert the test tube into the groove, and start the centrifuge. In the machine, the test tube centrifuges the material in the test tube with the high-speed rotation of the rotor. However, the material in the test tube is easily splashed out during the rotation and sprinkled in the groove or on the rotor, which is extremely difficult to clean.

Contents of the invention

The purpose of this utility model is to address the above problems, and prepare a centrifuge rotor device, so that the test tube can be inserted into the detachable test tube groove on the rotor, so as to facilitate the cleaning of the test tube groove.

In order to solve the above technical problems, the technical solution adopted by the utility model is: a centrifuge rotor device includes a rotor and a test tube slot, and the rotor is provided with several sockets for inserting the test tube slots, and the surface of one side of the socket close to the center of the circle is There is a strip-shaped slot on the top of the test tube slot. There is a cylindrical accommodation space inside the test tube slot. Inserts are arranged outside the test tube slot. The test tube slot and the rotor are detachably connected through the cooperation of the inserts and the slot. The test tube support is inserted into the storage space, and the opening of the test tube support is provided with an outward extension. When the test tube support is inserted into the storage space of the test tube groove, the extension of the test tube support will be engaged with the opening of the storage space. At the place, the test tube holder and the test tube groove have an interference fit.

Further, the upper part of the test tube groove is provided with a cover piece that can cover the upper part of the test tube groove.

Further, the test tube groove is provided with a protrusion, and the cover sheet is provided with a positioning hole for inserting the protrusion, and the positioning hole and the protrusion have an interference fit.

Further, the bump is L-shaped.

The advantages and positive effects that the utility model has are:

1. In the centrifuge rotor device described in the present invention, the test tube tank is detachably arranged on the rotor, which facilitates the disassembly and cleaning of the test tube tank, and a test tube support is provided in the test tube tank. If the solution needs to be centrifuged, directly put the The EP tube with solution is inserted into the test tube holder, and the extension of the test tube holder will prevent the solution in the EP tube from spilling into the test tube groove.

2. In the centrifuge rotor device described in this utility model, a cover is provided on the test tube groove, and the positioning hole on the cover is engaged with the L-shaped protrusion of the test tube groove, so that the EP tube containing the solution can be well placed. fixed in the test tube holder.

Detailed ways

Specific embodiments of the present utility model are described in detail below in conjunction with accompanying drawings.

As shown in Figure 1, a centrifuge rotor device includes a rotor 1 and a test tube slot 3. The rotor 1 is provided with several sockets for the test tube slot 3 to be inserted into. shaped slot 2, the inside of the test tube slot 3 is provided with a cylindrical accommodating space 5, the outside of the test tube slot 3 is provided with an insert 4, and the test tube slot 3 and the rotor 1 are detachably connected by the cooperation of the insert 4 and the slot 2, so A test tube holder 6 is movably inserted in the cylindrical accommodation space 5 of the test tube groove 3, and the opening of the test tube holder 6 is provided with an outward extension 7. When the test tube holder 6 is inserted into the accommodation space 5 of the test tube groove 3, The extension part 7 of the test tube holder 6 will be engaged with the opening of the accommodating space 5, and the test tube holder 6 and the test tube groove 3 have an interference fit. 8. The test tube groove 3 is provided with an L-shaped bump 10, and the cover sheet 8 is provided with a positioning hole 9 for inserting the bump 10, and the positioning hole 9 and the bump 10 are interference fit . When the solution in the EP tube needs to be centrifuged, the test tube holder 6 is inserted into the accommodating space 5 of the test tube groove 3. At this time, the extension part 7 of the test tube holder 6 will be engaged with the opening of the accommodating space 5, and the The EP tube containing the solution is inserted into the test tube holder 6, and the cover piece is covered on the top of the test tube groove 3. At this time, the cover piece 8 will press the EP tube and the test tube holder 6 tightly on the test tube groove 3, and the The cutting strip 4 of the test tube slot 3 is inserted into the slot 2 of the rotor 1. At this time, the test tube slot 3 and the rotor 1 are detachably connected through the cooperation of the cutting strip 4 and the slot 2, and the centrifuge is started to process the solution in the EP tube.
