Abstract

A low-speed table type centrifuge comprises a casing (6), a cover plate (1) and a control panel (5), wherein a centrifugal cavity (3) is arranged in the casing (6), the upper part of the centrifugal cavity (3) is sealed by a sealing ring (2), a rotating shaft (4) taking a motor as power is arranged at the center position in the centrifugal cavity (5), a check ring (8) is arranged in the middle of the rotating shaft (4), and a bamboo charcoal bag (7) is arranged on the check ring (8); the control panel (5) is arranged on the side face of the machine shell (6), and the control panel (5) is connected with a PLC (programmable logic controller) (10) at the bottom of the machine shell (6). The utility model discloses simple easy-to-use, in the pivot, the centrifugal chamber middle part is established the retaining ring and is improved the stability in centrifugal chamber, avoids beating of centrifuging process centrifuging tube. The bamboo charcoal bag on the retainer ring absorbs and removes the peculiar smell in the centrifugal chamber and purifies the environment. Utilize the sealing washer to prevent that centrifuging tube liquid from spilling over in the centrifugal chamber, extension centrifuge life.

Description

Low-speed table centrifuge

Technical Field

The utility model relates to a desk-top centrifuge of low-speed.

Background

A bench centrifuge is a machine that uses centrifugal force to separate components of a mixture of liquid and solid particles or liquid and liquid. Or separating two liquids with different densities and which are not mutually soluble in the emulsion (for example separating cream from milk), and separating gas mixtures with different densities by using a special overspeed tubular separator. Peculiar smell in the low-speed desktop centrifuge in the existing market is not easy to remove, and the center of gravity is not stable enough in the centrifugation process.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a desk-top centrifuge of low-speed, including casing, apron and control panel, establish the centrifugal chamber in the casing, centrifugal chamber top is sealed by the sealing washer, and the central point of centrifugal intracavity portion puts and is equipped with the pivot that uses the motor as power, establishes the retaining ring at the middle part of pivot, and support piece fixed connection is passed through with the retaining ring in the pivot. The retainer ring is circular, and a support piece is arranged at each 120-degree radius position on the retainer ring. The middle part of the supporting piece is provided with a bamboo charcoal bag; the control panel is arranged on the side face of the machine shell and is connected with the PLC controller at the bottom of the machine shell.

Furthermore, the control panel is provided with a rotating speed/centrifugal force/rotor number display window, a rotor number selection key, a parameter increment key, a parameter decrement key, a starting indicator light, a stopping indicator light, a time display window, a starting key and a stopping key.

The utility model discloses simple easy-to-use, in the pivot, the centrifugal chamber middle part is established the retaining ring and is improved the stability in centrifugal chamber, avoids beating of centrifuging process centrifuging tube. The bamboo charcoal bag on the retainer ring absorbs and removes the peculiar smell in the centrifugal chamber and purifies the environment. Utilize the sealing washer to prevent that centrifuging tube liquid from spilling over in the centrifugal chamber, extension centrifuge life.

Detailed Description

As shown in fig. 1 and 2, the low speed desktop centrifuge includes a housing 6, a cover 1, and a control panel 5. A PLC (programmable logic controller) 10 is fixedly arranged in a cavity at the bottom of the machine shell 6. The cover plate 1 is mounted on top of the cabinet 6. A centrifugal cavity 3 is arranged in the machine shell 6, the upper part of the centrifugal cavity 3 is sealed by a sealing ring 2, liquid in a centrifugal tube in the centrifugal cavity is prevented from overflowing, and the service life of the centrifugal machine is prolonged. The central position in the centrifugal cavity 5 is provided with a rotating shaft 4 which takes a motor as power. In the middle part of pivot 4, establish retaining ring 8 along 3 inner walls in centrifugal chamber, improve centrifugal chamber's stability, avoid beating of centrifuging process centrifuging tube. The rotating shaft 4 is fixedly connected with the retainer ring 8 through a supporting piece 9. The retainer ring 8 is circular, and a support member 9 is arranged on the retainer ring 8 at a radius of every 120 degrees. The box is placed in the middle of the supporting piece 9, the bamboo charcoal bags 7 with the same weight are arranged in the box, the peculiar smell in the centrifugal chamber is absorbed, and the environment is purified. The control panel 5 is arranged on the front face of the front end of the machine shell 6, and the control panel 5 is electrically connected with the PLC 10. The PLC controller 10 drives the motor to rotate.

The control panel 5 is provided with a rotating speed/centrifugal force/rotor number display window, a rotor number selection key, a parameter increment key, a parameter decrement key, a starting indicator light, a stopping indicator light, a time display window, a starting key and a stopping key.

The centrifuge tube is placed, the cover plate 1 is covered, and the centrifugal work can be started by pressing the start key.
