Description

A multi-connected eccentric clutch type rapid dissolution-separation integrated device

technical field

The invention relates to the technical field of chemical instruments, in particular to a multiple eccentric clutch type rapid dissolution-separation integrated device.

Background technique

Existing methods for accelerating the dissolution of substances mainly include stirring, shaking, heating, ultrasound and the like. Among them, stirring and shaking are relatively inefficient, and are likely to cause material loss and pollution during the dissolution process. The effect of heating is also relatively insignificant, and higher temperatures may cause volatilization of solvents or decomposition of solutes. Ultrasonic dissolution is currently the most commonly used high-efficiency dissolution method. However, when cavitation occurs, huge instantaneous pressure and high temperature will be generated locally at the moment when the cavitation bubble is compressed until it collapses, which may lead to some unstable The compound decomposes. In addition, material transfer between the two steps of dissolution and separation will inevitably lead to material loss or cross-contamination.

Contents of the invention

The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a simple structure, easy to use, suitable for substances with unstable chemical properties, which can avoid material loss and pollution, and can effectively dissolve and separate two operations in series Multi-connected eccentric clutch type rapid dissolution-separation integrated device to improve work efficiency.

The purpose of the present invention can be achieved through the following technical solutions: a multi-connected eccentric clutch type rapid dissolution-separation integrated device, characterized in that the device includes: a main shaft, a turntable fixed on the upper part of the main shaft, and rubber evenly distributed on the turntable Rolling balls, friction discs located under the turntable, each rubber rolling ball is provided with a dissolving centrifuge tube.

The rubber rolling ball has an empty groove dug from the upper opening, and inserts and fixes the dissolving centrifuge tube.

The rubber rolling ball is fixed on the turntable through the matching V-shaped ring. The V-shaped ring is two rings with different radii. , the ring with smaller radius is fixed under the turntable.

The bottom end of the rubber rolling ball is connected with a counterweight.

There are 2, 4, 6 or 8 rubber rolling balls.

Two armatures (9) are connected symmetrically below the friction disc (2), and an electromagnetic coil (8) is arranged between the friction disc (2) and the armature (9). When the electromagnetic coil (8) is energized, a Attractive force, attracting the armature (9) drives the friction disc (2) to slide upward along the direction of the main shaft (1), and contacts with the rubber rolling ball (6); the electromagnetic coil (8) is powered off, the friction disc (2) and the armature (9) Sliding down along the main shaft (1) under the force of gravity without contact with the rubber rolling ball.

The electromagnetic coil (8) is fixed to the bottom surface of the upper case (14) through a bracket, and the friction disc (2) is fixedly connected to the armature (9).

There are two electromagnetic coils (8), matched with the armature (9), symmetrically distributed on both sides of the rotating shaft.

The device is also provided with a controller, a power supply and a speed-regulating motor connected to the bottom of the main shaft. The controller adjusts the speed of the speed-regulating motor, controls the power on or off of the electromagnetic coil, and sets a timing program.

Each rubber rolling ball and the supporting V-shaped ring, counterweight, and dissolving centrifuge tube constitute a group of rolling ball units, and multiple groups of rolling ball units are evenly distributed on the turntable, and form a spin mechanism with the friction disc assembly.

The working principle of the present invention is as follows:

Dissolving mode: insert the dissolving centrifuge tube with a specified amount of solute and solvent into the empty groove of the rubber rolling ball, and set the speed in the low speed range. The friction disc goes up and contacts with the rubber rolling ball. When the turntable rotates, the counterweight is subjected to a large centrifugal force, which changes the inclination angle between the axis of the dissolving centrifuge tube and the plane of the turntable, which is less than 90° at rest. The higher the rotation speed, the smaller the inclination angle, the greater the deviation of the center of gravity of the dissolving centrifuge tube, and the greater the centrifugal force on the material in the tube. At the same time, due to the effect of the friction disc, the rubber rolling ball also rotates around its own axis. The direction of the resultant force generated by these two movements changes in the three-dimensional direction at any time, which will cause the solution flow mode in the dissolving centrifuge tube to change continuously, causing the fluid movement direction in the tube to change continuously, thus forming different eddy current changes , increase the degree of turbulence of the fluid in the dissolving centrifuge tube to intensify the eddy diffusion of solute molecules and accelerate the dissolution of materials.

Separation mode: disconnect the power supply of the electromagnetic coil, and set the speed to gradually accelerate from the low speed state to the high speed state, so that the friction disc will fall due to the gravity of the armature and itself, and will not contact the rubber rolling ball. This moment this device is exactly a centrifuge, plays separation effect.

Compared with the prior art, the beneficial effects of the present invention are reflected in the following aspects:

1. The dissolution process and the centrifugation process can be continuously carried out on the same device, and the timing program of the controller can be used to liberate the test personnel and improve work efficiency;

2. The dissolving process and centrifugal separation process can be carried out continuously in the same container, avoiding the loss, pollution and error caused by material transfer;

3. There is only rotation during the dissolution process, which can ensure the stability of the material structure;

4. The structure of the device is simple, easy to maintain and reliable in operation.

Detailed ways

The embodiments of the present invention are described in detail below. This embodiment is implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operating procedures are provided, but the protection scope of the present invention is not limited to the following implementation example.

The two rings are in the shape of a "V", and the opening direction faces the main shaft. The ring with a smaller radius is fixed below the turntable 4 . Described rubber rolling ball 6 bottom ends are connected with counterweight 7.

Two pieces of armatures 9 are symmetrically connected under the friction disc 2, and an electromagnetic coil 8 is arranged between the friction disc 2 and the armature 9. There are two electromagnetic coils 8, which are matched with the armature 9 and distributed symmetrically. On both sides of the rotating shaft 1, the friction disc 2 and the armature 9 are fixedly connected to form an integral body, and the electromagnetic coil 8 is fixed to the bottom surface of the upper case 14 through a bracket; when the electromagnetic coil 8 is energized, an attractive force is generated, and the attracting armature 9 drives the friction disc 2 along the direction of the main shaft 1 Slide upwards to contact with the rubber rolling ball 6; power off the electromagnetic coil 8, the friction disc 2 and the armature 9 slide down along the main shaft 1 under the action of gravity without contacting the rubber rolling ball. The device is also provided with a controller 10, a power supply 11 and a speed-regulating motor 12 connected to the bottom of the main shaft, the controller 10 regulates the speed of the speed-regulating motor 12, controls the power-on or power-off of the electromagnetic coil 8, and sets Timing program.

In this embodiment, the rubber rolling ball 6, the V-shaped ring 5, the counterweight 7 and the dissolving centrifuge tube 3 constitute a rolling ball unit, and there are 6 sets of rolling ball units.
