Example

[0036] Example (1):

[0037] In the biological fermentation experiment, the water and the lactic acid bacteria liquid are mixed at a ratio of 100:1. Since the bacteria liquid and the water are both liquid and easier to mix, circular motion with a small centrifugal force can be used. See Figure 4 , Both ends of the connecting rod 3 are connected to the crank 4 and the rocker 5, the rotation radius is selected to be the smallest, and the rotation radius of the crank 4 and the rocker 5 are the same, combined figure 1 , Figure 4 , The tray 6 and the container 1 are installed on the connecting rod 3. Due to the small centrifugal force and differential speed when the radius is small, the water and alcohol are mixed evenly after 5 minutes.

Example

[0038] Example (two):

[0039] In the detection of feed crude protein, water and sodium hydroxide need to be mixed according to the ratio of 100:40. Since water is liquid and potassium chloride is solid, the shaking required for dissolution is large, so a large centrifugal force is required. Circular motion. Installation method such as image 3 As shown, the two ends of the connecting rod 3 are respectively connected to the crank 4 and the rocker 5, the rotation radius is selected to be the largest, and the rotation radius of the crank 4 and the rocker 5 are the same, and the tray 6 and the container 1 are installed on the connecting rod 3. Due to the large centrifugal force and differential speed when running with a large radius, the water and potassium chloride are mixed evenly after 10 minutes.

Example

[0040] Example (three):

[0041] In the flocculation experiment, the polyacrylamide and water were mixed according to the ratio of 3:100. Since the polyacrylamide was partially dissolved, the solution became viscous. The more dissolved, the greater the viscosity. It is more difficult to completely dissolve it by rotating centrifugal force. The horizontal one-way sloshing method is required, that is, the difference between the inertia of the solute and the solution movement is used to accelerate the dissolution. Installation method such as Figure 5 As shown, the two ends of the connecting rod 3 are respectively connected to the crank 4 and the rocker 5, the rotation radius of the crank 4 is selected to be the smallest, the rotation radius of the rocker 5 is larger than the crank 4, and the tray 6 and the container 1 are placed on the top of the rocker 5. During operation, the crank 4 moves in a circle, and the rocker 5 moves back and forth along a circular arc track. During ope...

Abstract

The invention relates to a shaking machine for a biochemical test. The shaking machine is characterized by comprising a frame (2), wherein a motor (7) is fixedly arranged on the frame (2); an output shaft of the motor (7) is vertically upward and connected with a coupling (8); the coupling (8) is connected with a crank (4) horizontally arranged; the crank (4) is also hinged with a connecting rod (3); the connecting rod (3) is also hinged with a rocking bar (5); the rocking bar (5) is also hinged with the frame (2); a tray (6) is fixedly arranged above the connecting rod (3) or the rocking bar (5); a container (1) is fixed on a clamp (9) on the tray; and the motor (7) is started, the output shaft drives the crank (4) to rotate around the coupling, the crank (4) drives the end point of the connecting rod (3) connected with the crank (4) to synchronously rotate, and the connecting rod (3) drives the rocking bar (5) to rotate or swing around a hinge point of the rocking bar (5) and the frame (2).

Description

technical field [0001] The invention relates to a shaker, in particular to a shaker for biochemical tests and a shaker method thereof, which is used for mixing multiple reagents in biochemical experiments, and belongs to the technical field of mechanical devices. Background technique [0002] At present, in biochemical experiments, there will be a variety of materials with different phases that need to be mixed uniformly. Generally, stirring is carried out by contact objects such as glass rods, paddles or rotors, but after mixing, materials will adhere to the contact objects, resulting in inaccurate proportioning and affecting the experiment. Therefore, it is an ideal way to shake well without contacting the material. Most of the shakers used in the laboratory or factory are simple rotary or one-way shaking type, which is aimed at a single phase of mixing, and the rotary type is mostly used for mixing liquid-liquid or solid-liquid phase materials, and one-way shaking type. ...
