Description

Technical Field

[0001] This utility model belongs to the field of liquid separator technology, specifically relating to a mixing and stirring liquid separator. Background Technology

[0002] Currently, when preparing cell fixative (methanol: glacial acetic acid = 3:1) in medical laboratories, operators need to manually pour methanol and glacial acetic acid into graduated cylinders separately, mix them manually, and then transfer them into a dispenser. However, glacial acetic acid is highly volatile and has a strong, irritating odor, which causes the fixative to evaporate during preparation, polluting the laboratory environment and affecting the health of operators. Furthermore, evaporation can alter the fixative ratio, affecting experimental results. Manual stirring during the mixing process is inefficient and often results in uneven mixing. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, this utility model proposes a mixing and stirring separator.

[0004] The specific technical solution of this utility model is as follows: A mixing and stirring separator includes: a measuring cylinder, a piston cylinder slidably connected to the measuring cylinder, a mixing and stirring mechanism installed on the piston cylinder, an input pipe installed at the bottom of the measuring cylinder, and an output pipe installed on the side wall of the measuring cylinder. The mixing and stirring mechanism includes: a through hole, a through hole provided on the piston cylinder, a pull-out cylinder slidably connected inside the through hole, a micro motor installed inside the pull-out cylinder, an impeller installed on the output shaft of the micro motor, the impeller being placed outside the pull-out cylinder, and an electric switch installed on the pull-out cylinder, the electric switch being electrically connected to the micro motor.

[0005] Furthermore, a limit mechanism is provided between the through hole and the pull tube.

[0006] Furthermore, the limiting mechanism includes: a blind hole, a blind hole is provided on the side wall of the through hole, a locking block is slidably connected in the blind hole, the bottom of the blind hole is connected to the locking block by a thrust spring, and a locking groove is provided on the side wall of the pull tube for cooperating with the locking block, the locking block and the locking groove cooperate to limit the pull tube.

[0007] Furthermore, a sealed bearing is provided between the output shaft of the micro motor and the pull-out tube.

[0008] Furthermore, an activated carbon composite adsorption layer is installed on the piston cylinder.

[0009] Furthermore, a check valve is installed inside the input pipe.

[0010] Furthermore, a threaded cap is installed on the input pipe.

[0011] Furthermore, a valve is installed on the output pipe.

[0012] Furthermore, a filter screen is installed on the input pipe.

[0013] Beneficial effects:

[0014] This application utilizes a piston cylinder slidably connected to a graduated cylinder, on which a mixing and stirring mechanism is installed. This allows operators to draw methanol and glacial acetic acid into a separator during cell fixation preparation, mixing them directly within the separator. This prevents prolonged contact of glacial acetic acid with outside air, avoiding evaporation that could pollute the laboratory environment and harm operators' health. It also prevents imbalances in the fixative ratio due to evaporation, thus improving experimental results. Furthermore, the piston cylinder has a through-hole through which a pull-out cylinder slidably connects. A micro-motor is installed inside the pull-out cylinder, with an impeller mounted on its output shaft. The impeller is positioned outside the pull-out cylinder, which is equipped with an electric switch electrically connected to the micro-motor. This allows operators to control the micro-motor to drive the impeller, mixing the methanol and glacial acetic acid in the graduated cylinder. This avoids uneven mixing caused by manual stirring and improves mixing efficiency. Attached Figure Description

[0022] Example 1: A mixing and stirring separator includes: a measuring cylinder 1, a piston cylinder 2 slidably connected to the measuring cylinder 1, a mixing and stirring mechanism 3 mounted on the piston cylinder 2, an input pipe 4 mounted at the bottom of the measuring cylinder 1, and an output pipe 5 mounted on the side wall of the measuring cylinder 1. The mixing and stirring mechanism 3 includes: a through hole 31, the piston cylinder 2 having a through hole 31, a pull-out cylinder 32 slidably connected within the through hole 31, a micro motor 33 mounted within the pull-out cylinder 32, an impeller 34 mounted on the output shaft of the micro motor 33, the impeller 34 being positioned outside the pull-out cylinder 32, and an electric switch 35 mounted on the pull-out cylinder 32, the electric switch 35 being electrically connected to the micro motor 33. This application, by having a piston cylinder 2 slidably connected to the measuring cylinder 1 and a mixing and stirring mechanism 3 mounted on the piston cylinder 2, allows the operator to draw methanol and glacial acetic acid into the separator when preparing cell fixative. The liquid separator allows for direct mixing of glacial acetic acid within the measuring cylinder, preventing prolonged contact with outside air and avoiding evaporation that could contaminate the laboratory environment and harm the health of operators. It also prevents imbalances in the fixed-liquid ratio due to evaporation, thus improving experimental results. Furthermore, the piston cylinder 2 has a through-hole 31, within which a sliding pull-out cylinder 32 is slidably connected. A micro motor 33 is installed inside the pull-out cylinder 32, and an impeller 34 is mounted on its output shaft. The impeller 34 is positioned outside the pull-out cylinder 32, and an electric switch 35 is installed on the pull-out cylinder 32. This electric switch 35 is electrically connected to the micro motor 33, allowing operators to control the micro motor 33 to drive the impeller 34 to mix the methanol and glacial acetic acid in the measuring cylinder 1. This avoids uneven mixing caused by manual stirring and improves mixing efficiency.

A locking block 62 is slidably connected inside the hole 61 and the blind hole 61. The bottom of the blind hole 61 and the locking block 62 are connected by a thrust spring 63. The side wall of the pull-out cylinder 32 is provided with a slot 64 for cooperating with the locking block 62. The locking block 62 and the slot 64 cooperate to limit the movement of the pull-out cylinder 32, so that the movement of the pull-out cylinder 32 can be limited, preventing the pull-out cylinder 32 from exceeding the working stroke during the movement, and improving the convenience of use.

[0025] Example 4: Based on Example 1, a sealed bearing 7 is provided between the output shaft of the micro motor 33 and the pull tube 32. This application improves the sealing performance by providing a sealed bearing 7 between the output shaft of the micro motor 33 and the pull tube 32, and prevents the fixative liquid from entering the pull tube 32 through the space between the output shaft of the micro motor 33 and the pull tube 32 during the mixing process.

[0026] Example 5: Based on Example 1, an activated carbon composite adsorption layer 8 is installed on the piston cylinder 2.

[0027] Example 6: Based on Example 1, a check valve 9 is installed in the input pipe 4. This application avoids backflow of the fixative during use by installing a check valve 9 in the input pipe 4, thus improving the ease of use.

[0028] Example 7: Based on Example 1, a threaded cap 10 is installed on the input pipe 4. This application allows the operator to install the dispenser on the mouth of the solution bottle by installing a threaded cap 10 on the input pipe 4, thus preventing the liquid in the solution bottle from evaporating.

[0029] Example 8: Based on Example 1, a valve 11 is installed on the output pipe 5. This application improves the safety of use by installing a valve 11 on the output pipe 5 to prevent the fixed liquid in the measuring cylinder 1 from flowing out during the suction and mixing process.

[0030] Example 9: Based on Example 1, a filter screen 12 is installed on the input pipe 4. This application avoids the solid precipitate in the solution bottle from clogging the input pipe 4 by installing a filter screen 12 on the input pipe 4, thereby improving the ease of use.

[0031] Work process:

[0032] When mixing the fixative solution, first install 10 on the mouth of the methanol or glacial acetic acid solution bottle, pull the piston cylinder 2 upward to draw the solution in the bottle into the measuring cylinder 1, and then draw another solution in the same way. Push the pull cylinder 32 downward to drive the impeller 34 to move through the micro motor 33, so that the impeller 34 is placed inside the mixed solution. At the same time, the movement of the pull cylinder 32 causes the locking block 62 to disengage from the locking groove 64 and unlock. Then, turn on the micro motor 33 through the electric switch 35 to drive the impeller 34 to rotate and stir the mixed solution. After mixing is completed, turn off the electric switch 35 and pull the pull cylinder 32 upward to reset it so that the locking block 62 and the locking groove 64 re-engage and lock. When it is necessary to output the fixative solution, first open the valve 11, and then push the piston cylinder 2 downward to let the fixative solution in the measuring cylinder 1 flow out through the output pipe 5 and the valve 11.
