DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] Embodiment 1, by Figure 1-Figure 4 The utility model includes a reactor 1, a rotating shaft 6 is rotatably installed inside the reactor 1, the rotating shaft 6 is rotatably connected to the middle of the top of the reactor 1, the top of the rotating shaft 6 is fixedly connected to the output shaft of the motor 8, the motor 8 is fixedly installed on the top of the reactor 1, the outer bottom end of the rotating shaft 6 is evenly installed with stirring blades 7, and the outer side of the rotating shaft 6 is installed with a degassing component 9;

[0025] The bubble removal assembly 9 includes a floating block 903 sleeved on the outside of the rotating shaft 6, a side rod 904 is installed at an equal angle on the outside of the floating block 903, and a pointed cone 905 is evenly installed on the outer wall of the side rod 904. A guide bar 901 is installed at an equal angle on the outside of the rotating shaft 6, and a guide groove 906 is installed at an equal angle on the inside of the floating block 903. The guide bar 901 is slidably connected to the guide groove 906. Under the action of buoyancy, the floating block 903 always floats above the liquid surface, which is convenient for removing bubbles from solutions with different liquid levels. At the same time, the floating block 903 is slidably connected with the guide bar 901 through the guide groove 906, so that the floating block 903 rotates with the rotating shaft 6, which facilitates the contact between the pointed cone 905 on the side rod 904 and the bubbles on the liquid surface, thereby improving the bubble removal effect and the reaction efficiency. An electromagnet 902 is installed on the inner top wall of the reactor 1, and the electromagnet 902 is connected to an external power supply. A magnetic block 907 is installed on the top of the floating block 903. When the electromagnet 902 is energized, it generates an attraction to the magnetic block 907, and the electromagnet 902 and the magnetic block 907 are attracted to the outer wall of the rotating shaft 6. A positioning cross bar 908 is installed on the side, the bottom wall of the positioning cross bar 908 is located above the floating block 903, and the top wall of the positioning cross bar 908 is located below the electromagnet 902. A top cylinder 909 is installed on the top of the reactor 1, and a positioning stopper 910 is movably installed inside the top cylinder 909. The bottom end of the positioning stopper 910 penetrates into the interior of the reactor 1, and the top end of the positioning stopper 910 is fixedly connected to the output end of the cylinder 911. The cylinder 911 is fixedly installed on the top of the top cylinder 909. The positioning stopper 910 is fixedly connected to the output end of the cylinder 911. When the positioning cross bar 908 is in contact, the magnetic block 907 and the electromagnet 902 are in the same longitudinal straight line. After the reaction is completed, the output end of the cylinder 911 pushes the positioning stop rod 910 to move downward to the inside of the reactor 1. When the positioning cross bar 908 is in contact with the positioning stop rod 910, the electromagnet 902 and the magnetic block 907 are in the same longitudinal straight line, which makes it convenient for the electromagnet 902 to generate an attractive force on the magnetic block 907 when the floating block 903 is recovered, so that the floating block 903 can be recovered after the reaction is completed, which is convenient for subsequent use.

[0026] A liquid inlet pipe 3 is installed at the top of the reactor 1, a liquid outlet pipe 4 is installed at the bottom of the reactor 1, a valve 5 is installed on the liquid outlet pipe 4, and a supporting leg 2 is installed at the bottom of the reactor 1 at an equal angle.

[0027] Working principle: When in use, the raw material solution for 5-aminolevulinic acid biosynthesis is put into the reactor 1 from the liquid inlet pipe 3, and the motor 8 is turned on to rotate the shaft 6, which in turn drives the stirring blade 7 to rotate, mix the raw material solution, and accelerate the reaction;

[0028] During the reaction, bubbles are continuously generated in the solution, some of which are broken during the rotation of the stirring blade 7, while the other part of the bubbles float to the liquid surface. Since the stirring blade 7 is located below the liquid surface, it is not convenient to break the bubbles that float to the liquid surface.

[0029] After the raw material solution completely enters the reactor 1, the power supply of the electromagnet 902 is disconnected, the attraction of the electromagnet 902 to the magnetic block 907 disappears, and the floating block 903 falls under the action of gravity. When the floating block 903 enters the solution, under the action of buoyancy, the floating block 903 floats on the surface of the solution. At the same time, the floating block 903 is slidably connected with the guide strip 901 on the outer wall of the rotating shaft 6 through the guide groove 906, so that the floating block 903 can rotate with the rotating shaft 6, so that the pointed cone 905 on the side rod 904 breaks the bubbles on the liquid surface, thereby improving the bubble breaking effect and the reaction efficiency.

[0030] When the reaction is over, the cylinder 911 is turned on to move the positioning stop rod 910 downward, and the rotating shaft 6 continues to rotate until the positioning cross bar 908 contacts the positioning stop rod 910, and the motor 8 stops. At this time, the electromagnet 902 and the magnetic block 907 are in the same longitudinal straight line. At this time, the electromagnet 902 is energized to generate an attraction for the magnetic block 907, which facilitates the adsorption and recovery of the floating block 903 for subsequent use.
