Description

Technical Field

[0001] The utility model relates to the technical field of reaction kettles, in particular to a mixing and stirring device for an organic reaction kettle. Background Art

[0002] A reactor is a comprehensive reaction vessel. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. The existing reactor generally includes a reactor body, a reactor cover, a heating device and a stirring device. There is a reaction chamber inside the reactor body. The stirring device extends into the reaction chamber through the reactor cover to stir the material. Usually, the solution is added to the inside of the reactor first, and then the solid solute that needs to react is added. When the solid solute is in the form of smaller particles, it is easy to float on the upper layer of the solution. The traditional mixing device cannot effectively stir the solid solute to the lower layer of the solution, which affects the dissolution reaction between the solid solute and the solution.

[0003] For example, a mixing device for a pressure reactor disclosed in a Chinese patent document (publication number: CN217855846U) can stir the solid solute floating on the top of the solution to the bottom of the solution through the second connecting ring, the third connecting ring and the second stirring plate, so that the dissolution reaction between the solution and the solute is faster and more uniform.

[0004] However, after the solid solute is added through the feed port, the second stirring blade cannot stir and mix all the solid solute in time, so most of the solid solute will float above the solution in the reactor. Since the second stirring blade is a fixed stirring, most of the solid solute cannot be quickly stirred with the solution, thereby reducing the reaction efficiency between the solid solute and the solution.

[0024] Reference Figure 1-4 A mixing and stirring device for an organic reactor, comprising a reactor body 1, a cover body 2 is fixedly connected to the upper surface of the reactor body 1, a feed pipe 3 is fixedly connected to the upper surface of the cover body 2, a rotating sleeve 4 is installed on the upper surface of the cover body 2 through a bearing, a worm gear 5 is fixedly sleeved on the outer surface of one end of the rotating sleeve 4, the other end of the rotating sleeve 4 penetrates and extends to the interior of the reactor body 1, and the other end of the rotating sleeve 4 is fixedly connected to the outer surface of the rotating blocks 6 distributed in a ring array;

[0025] A mixing device is provided on the lower surface of the rotating block 6 , and the mixing device includes a rotating rod 7 , and an outer surface of one end of the rotating rod 7 is mounted on the lower surface of the rotating block 6 through a bearing.

[0026] The outer surface of the rotating rod 7 is fixedly sleeved with a driven gear 71, and the other end of the rotating rod 7 is fixedly connected to a limiting slide bar 72, and the lower end of the limiting slide bar 72 is fixedly connected to a stopper 73. The outer surface of the limiting slide bar 72 is movably sleeved with a buoyancy movable sleeve 74, and the stopper 73 serves to limit the lower end of the limiting slide bar 72 to prevent the buoyancy movable sleeve 74 from falling off. The outer surface of the buoyancy movable sleeve 74 is fixedly connected with stirring blades 75 distributed in a ring array, and the buoyancy movable sleeve 74 serves to float above it according to the height of the solution. The stirring blades 75 are inclined so that one end of the stirring blades 75 is inserted into the solution, which is convenient for driving the solution to mix with the solid solute when rotating. A first servo motor 76 is fixedly installed on the upper surface of the cover body 2, and a worm 77 is fixedly installed on the output shaft of the first servo motor 76 through a coupling. The outer surface of the worm 77 meshes with the tooth surface of the worm wheel 5, and a mounting bracket 78 is fixedly connected to the upper surface of the cover body 2.

[0027] A second servo motor 79 is fixedly mounted on the inner wall of the mounting bracket 78, and a rotating shaft 710 is fixedly mounted on the output shaft of the second servo motor 79 through a coupling. One end of the rotating shaft 710 passes through the rotating sleeve 4 and extends to the interior of the reactor body 1. A stirring kettle 711 is fixedly connected to the outer surface of the rotating shaft 710. A driving gear 712 is fixedly sleeved on the outer surface of the rotating shaft 710. The tooth surfaces of multiple driven gears 71 are all meshed with the tooth surfaces of the driving gear 712. The second servo motor 79 drives the stirring kettle 711 to rotate and stir through the rotating shaft 710, and drives the driving gear 712 to rotate. The rotation of the driving gear 712 drives the meshing driven gear 71 to rotate. A discharge pipe 713 is fixedly connected to the lower surface of the reactor body 1. A solenoid valve 714 is fixedly mounted on the outer surface of the discharge pipe 713. The solenoid valve 714 controls the flow of materials in the discharge pipe 713 and is connected to an external PLC control program.

[0028] By providing a mixing device, the solid solute floating on the solution can be efficiently stirred and mixed in a rotating manner, thereby improving the reaction efficiency between the solid solute and the solution.

[0029] Working principle: Step 1, first add the solution into the reactor body 1 through the feed pipe 3. The addition of the solution causes the buoyancy moving sleeve 74 to rise along the limit slide bar 72 through the buoyancy of the solution, and always floats above the solution. At this time, the second servo motor 79 is started to work, and the second servo motor 79 drives the rotating shaft 710 to rotate clockwise. The rotation of the rotating shaft 710 drives the stirring kettle 711 to mix and stir the solution, and drives the driving gear 712 to rotate;

[0030] Step 2: Add the solid solute into the reactor body 1 through the feed pipe 3. The solid solute will float above the solution. At this time, start the first servo motor 76. The first servo motor 76 drives the meshing worm wheel 5 to rotate through the worm 77. The rotation of the worm wheel 5 drives the rotating sleeve 4 to rotate counterclockwise. The rotation of the rotating sleeve 4 drives the multiple rotating rods 7 to rotate in a circle through the rotating block 6. While the rotating rod 7 rotates in a circle, the driving gear 712 and the meshing driven gear 71 drive the rotating rod 7 to rotate on its own. The rotation of the rotating rod 7 drives the stirring blade 75 to rotate through the cooperation of the limiting slide bar 72 and the buoyancy movable sleeve 74, thereby stirring the floating solid solute to make it mix and react with the solution. Through the self-rotation and circular rotation of the stirring blade 75, the solid solute floating in the reactor body 1 is fully stirred to make it quickly mix and react with the solution.
