Description

Technical Field

[0001] The utility model relates to the technical field of biological reagents, and in particular to a high-precision biological reagent mixing device. Background Art

[0002] Biological reagents refer to biological materials or organic compounds related to life science research, as well as reagents used in clinical diagnosis and medical research. Since life science is broad and developing rapidly, such reagents are of various types and complex in nature. Therefore, a biological reagent mixing device is needed to mix them. The existing biological reagent mixing device has a relatively simple structure and cannot mix the biological reagents evenly, thereby reducing the mixing quality of the biological reagents and reducing the working efficiency of the mixing device. Therefore, we propose a biological reagent mixing device.

[0003] After searching, the Chinese patent announcement number is CN215277002U, which discloses a biological reagent mixing device. In this patent, reagents and mixed agents are transmitted to the inner cavity of the mixing box through a liquid inlet pipe. By turning on the motor, the output shaft of the motor drives the rotating rod to rotate, and the rotating rod drives the stirring rod to rotate while rotating to mix and stir the reagents. Then, the stirring rod drives the scraper to rotate, and the scraper is used to scrape off the reagents adhering to the inner wall of the mixing box. At the same time, by turning on the electric push rod, the electric push rod starts to move back and forth, and the electric push rod drives the mixing box to move back and forth. The reagents in the inner cavity of the mixing box are fully mixed while the mixing box moves. The movement trajectory of the mixing box is limited by the T-shaped limit block and the T-shaped limit groove. After the mixing is completed, the electromagnetic valve is opened, and the stirred and mixed reagents are discharged through the liquid discharge pipe, thereby completing the uniform mixing of the biological reagents, solving the problem that the existing biological reagent mixing device has a relatively single structure and cannot well mix the biological reagents, thereby reducing the mixing quality of the biological reagents and reducing the working efficiency of the mixing device;

[0004] However, when the above device is in use, due to the different components in some biological reagents, some biological reagents are prone to precipitation at low temperatures. The above device cannot be quickly stirred and mixed during operation. At the same time, after stirring and mixing, the biological reagents attached to the inner wall of the above device are difficult to flow downward, thereby causing waste of biological reagents.

At the same time, the start of the heating plate can be controlled, thereby achieving the goal of increasing the temperature of the inner cavity of the barrel during the mixing process of the biological reagents, facilitating the rapid melting and mixing of some biological reagents that are easy to precipitate.

The bottom of the inner cavity passes through the top of the inner cavity of the barrel 1, and the bottom of the right side of the inner cavity of the discharge pipe 6 is parallel to the bottom of the inner cavity of the barrel 1. Therefore, when in use, the threads provided on the inner wall of the feed pipe 3 and the outer surface of the discharge pipe are used to facilitate the installation of other connecting equipment, so as to realize the entry of raw materials and the discharge after mixing. The bottom side wall of the barrel 1 is detachably installed with a heating plate 7, and the control panel 5 is electrically connected to the motor 2 and the heating plate 7 through a wire passing through the outer wall of the barrel 1. Therefore, when in use, the start and stop of the motor 2 are automatically controlled by the control panel 5, so as to control whether the biological reagent in the inner cavity of the barrel 1 is stirred and mixed. At the same time, the start of the heating plate 7 can be controlled, thereby realizing the increase of the inner cavity temperature of the barrel 1 during the mixing process of the biological reagent, which is convenient for some biological reagents that are easy to precipitate. Rapid melting and mixing, a cylinder 8 is rotatably installed in the middle of the inner cavity of the cylinder 1, and the part of the cylinder 8 extending out of the top of the cylinder 1 is connected to the output shaft at the bottom of the motor 2, so that when in use, the motor 2 is started to drive the cylinder 8 to rotate, and a plurality of strip grooves 9 are provided on the outer surface of the cylinder 8. A telescopic rod 10 is movably installed in the inner cavity of the strip groove 9 through a circular axis. The length of the telescopic rod 10 after stretching is the same as the length of the radius of the cross-section of the inner cavity of the cylinder 1, and the bottom of the other end of the telescopic rod 10 is designed as an inclined surface, so that when in use, the cylinder 8 rotates, and under the action of centrifugal force, the telescopic rod 10 rotates and moves out of the inner cavity of the strip groove 9, and then the telescopic rod 10 is stretched until one end of the telescopic rod 10 fits the inner wall of the inner cavity of the cylinder 1, so as to quickly and fully mix and stir the biological test material in the inner cavity of the cylinder 1 A plurality of stirring rods 11 are fixedly installed at the bottom of the outer surface of the cylinder 8, and the stirring rods 11 are located at the position where the outer surface of the cylinder 8 fits the bottom of the inner cavity of the cylinder 1. The stirring rods 11 are evenly distributed at the bottom of the outer surface of the cylinder 8, and the side of the stirring rods 11 away from the cylinder 8 fits the inner wall of the cylinder 1. When in use, the shape and position of the stirring rods 11 are utilized to fully mix the biological reagent at the bottom of the inner cavity of the cylinder 1 when the cylinder 8 rotates, so as to improve the mixing effect. A floating plate 12 is movably installed on the outer surface of the cylinder 8, and the floating plate 12 is constructed of a material with a density less than that of water.

The floating plate 12 is sleeved on the outer surface of the cylinder 8, and the upper and lower sides of the circular hole in the middle of the floating plate 12 are both arc-shaped.

[0024] Working principle: When working, first connect the connecting device with the feed pipe 3 and the discharge pipe 6 through the connecting pipe, then introduce the biological reagent to be mixed into the inner cavity of the cylinder 1 through the feed pipe 3, then control the motor 2 and the heating plate 7 to start through the control panel 5, so that the cylinder 8 rotates, and under the action of centrifugal force, the telescopic rod 10 rotates out of the strip groove 9, and then stretches the telescopic rod 10, and cooperates with the stirring rod 11 set at the bottom of the cylinder 8 to fully mix the biological reagent in the inner cavity of the cylinder 1. During mixing, the heating plate 7 starts to heat the bottom inner wall of the cylinder 1, so as to prevent the biological reagent from precipitating at the bottom of the inner cavity of the cylinder 1, thereby causing uneven stirring and mixing of the biological reagent;

[0025] During stirring and mixing, due to the material of the floating plate 12 itself, the floating plate 12 is always on the top of the biological reagent liquid surface. After the biological reagent is mixed, the control panel 5 controls the valve in the inner cavity of the discharge pipe 6 to open, so that the mixed biological reagent is discharged from the discharge pipe 6. As the biological reagent is discharged, the floating plate 12 in the inner cavity of the cylinder 1 also moves downward, and the outer surface of the floating plate 12 fits the inner wall of the cylinder 1. When the floating plate 12 moves downward, it automatically scrapes off the biological reagent attached to the inner wall of the cylinder 1, thereby reducing the waste of biological reagent.

[0026] In summary, compared with general similar devices, this high-precision biological reagent mixing device has the advantages of rapid and uniform mixing and effective discharge to prevent the mixed reagents from adhering to the inner wall of the stirring container and causing waste.
