Description

Technical Field

[0001] This utility model belongs to the field of solution stirring technology, specifically a solution stirring and heat preservation device. Background Technology

[0002] In the chiral ester process, indanone is used as the starting material to generate chiral esters under the action of enzyme catalysis. The process requires mixing reagents such as dimethyl carbonate, toluene, sodium methoxide solution, and toluene solution, so a stirring device is essential to make the various solutions and powders blend together. In the existing technology, stirring and mixing and heating and evaporation generally occur in two separate devices and are carried out in sequence to complete the experiment.

[0003] A Chinese patent with authorization announcement number CN211537534U discloses a solution heating and stirring device, including a lifting device, a stirring device, and a heating device. The device includes a hydraulic actuator, a hydraulic actuator telescopic column, a motor, a rotating shaft, a stirring paddle, a heat transfer fluid, a heating tube, and a temperature controller. The hydraulic actuator controls the height position of the stirring paddle in the solution to facilitate uniform stirring. The heating tube heats the heat transfer fluid in the side wall cavity. This invention provides uniform heating and stirring, is simple, and has high efficiency.

[0004] However, the above solution still has some problems. In the chiral ester process, the solution is rotated in the tank due to stirring, and there is no obstruction above the tank, which causes the solution to splash out from the tank opening, resulting in inaccurate final production data of the chiral ester process. Therefore, a solution stirring and heat preservation device is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and address the problems of existing equipment, this utility model proposes a solution stirring and heat preservation device.

[0006] The technical solution adopted by this utility model to solve its technical problem is a solution stirring and heat preservation device, including: a support frame and a tank. A drive motor is fixedly connected to the upper surface of the support frame. A stirring rod is fixedly connected to the output end of the drive motor. Multiple sets of stirring blades are fixedly connected to the stirring rod. A baffle is fixedly connected to the stirring rod. A first limiting groove is symmetrically opened on the inner wall of the baffle. A spring is fixedly connected to the inner wall of the baffle. An extension plate is fixedly connected to one end of the spring. The extension plate is slidably connected inside the baffle. Limiting blocks are symmetrically arranged on the upper and lower surfaces of the extension plate. The limiting blocks are slidably connected inside the first limiting groove. A second limiting groove is symmetrically opened inside the extension plate. Two sets of arc-shaped limiting rods are slidably connected inside the two sets of second limiting grooves. A connecting plate is fixedly connected between the two sets of arc-shaped limiting rods. The connecting plate is slidably connected inside the second limiting groove. When the drive motor is started, the stirring blades are driven to rotate through the stirring rod, thereby stirring the solution and powder in the tank.

[0007] Preferably, the stirring rod extends into the interior of the tank, the baffle is located above the tank, an insulation layer is fixedly connected to the outer surface of the tank, and a heating pipe is installed inside the insulation layer. The heat generated by the heating pipe is transmitted into the interior of the tank through the insulation layer, thereby heating the tank and thus heating the solution.

[0008] Preferably, a heat insulation pad is provided inside the insulation layer. The heat insulation pad is located outside the heating tube. The heat insulation pad can lock the heat generated by the heating tube between the heating tube and the insulation layer, so that the tank is kept in a heat-insulating state when the heating tube is turned off.

[0009] Preferably, the outer surface of the insulation layer is symmetrically provided with connecting frames, a first hinge rod is hinged to the connecting frame, a hollow frame is hinged to the first hinge rod, and a positioning hole is provided on the hollow frame. The first hinge rod can connect the connecting frame and the hollow frame, thereby ensuring the stability of the hollow frame.

[0010] Preferably, a reinforcing rod is slidably connected inside the hollow frame, and an elastic plate is fixedly connected inside the reinforcing rod. A positioning block is fixedly connected to the elastic plate. When the pressure on the elastic plate decreases, the positioning block moves upward and enters the positioning hole, thereby fixing the position of the reinforcing rod.

[0011] Preferably, the positioning block is movably connected inside the positioning hole, and one end of the reinforcing rod is hinged to a second hinge rod, on which an anti-slip pad is hinged. The anti-slip pad can increase the friction between the rod and the tabletop, thereby improving the support strength of the can.

[0012] The advantages of this invention are as follows: a shielding component is provided above the open tank to prevent solution splashing during stirring, and it does not affect the addition of solution before stirring or the removal of solution after stirring. The centrifugal force generated when the baffle rotates throws the extension plate outward. The four baffles are connected by four connecting plates. When the baffles are thrown out, the surfaces that are in contact separate, so that the connecting plates can shield the gaps between the baffles. In this way, with the cooperation of the baffles, extension plates and connecting plates, the opening at the top of the tank can be shielded during stirring, thereby preventing solution splashing during stirring from affecting the accuracy of the final production data of the chiral ester process.

[0013] This invention adds reinforcing components to both sides of the tank, improving its stability. The hollow frames on both sides are rotated outward about the first hinge rod as the axis, and then the reinforcing rod is pulled outward from the hollow frame. The elastic plate drives the positioning block to move into the positioning hole, fixing the position of the reinforcing rod. Then, the anti-slip pad is rotated about the second hinge rod as the axis, so that the bottom of the anti-slip pad is in contact with the table. This forms a triangle between the anti-slip pad, the table, the reinforcing rod, the hollow frame, and the insulation layer, improving the support strength of the tank and preventing the tank from falling.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5As shown, a solution stirring and heat preservation device includes: a support frame 1 and a tank 13. A drive motor 2 is fixedly connected to the upper surface of the support frame 1. A stirring rod 3 is fixedly connected to the output end of the drive motor 2. Multiple sets of stirring blades 4 are fixedly connected to the stirring rod 3. A baffle 5 is fixedly connected to the stirring rod 3. A first limiting groove 6 is symmetrically opened on the inner wall of the baffle 5. A spring 7 is fixedly connected to the inner wall of the baffle 5. An extension plate 8 is fixedly connected to one end of the spring 7. The extension plate 8 is slidably connected inside the baffle 5. Limiting blocks 9 are symmetrically arranged on the upper and lower surfaces of the extension plate 8. The limiting blocks 9 are slidably connected to the first limiting groove 6. Inside the tank 6, the extension plate 8 is symmetrically provided with second limiting grooves 10. Two sets of arc-shaped limiting rods 11 are slidably connected inside the two sets of second limiting grooves 10. A connecting plate 12 is fixedly connected between the two sets of arc-shaped limiting rods 11. The connecting plate 12 is slidably connected inside the second limiting grooves 10. The stirring rod 3 extends into the tank body 13. The baffle 5 is located above the tank body 13. A heat insulation layer 14 is fixedly connected to the outer surface of the tank body 13. A heating pipe 15 is provided inside the heat insulation layer 14. A heat insulation pad 16 is provided inside the heat insulation layer 14. The heat insulation pad 16 is located outside the heating pipe 15.

[0023] The stirring and heating devices are combined into one unit, allowing for simultaneous heating or heat preservation of the solution during the chiral ester production process. This improves the efficiency of solution and reagent fusion. A shielding component is installed above the open tank 13 to prevent solution splashing during stirring, without affecting the addition of solution before stirring or the removal of solution after stirring. In actual use, starting the drive motor 2 drives the stirring blades 4 and baffles 5 to rotate simultaneously via the stirring rod 3. The stirring blades 4 stir the solution in the tank 13, and the centrifugal force generated by the rotation of the baffles 5 throws the extension plate 8 outward, causing the spring 7 to extend and simultaneously causing the limiting block 9 to slide within the first limiting groove 6, preventing the extension plate 8 from falling off the baffles 5. The four sets of baffles 5 are connected by four sets of plates. When the baffle 5 is thrown out, the contact surfaces separate, so the connecting plate 12 can block the gap between the baffles 5. The arc-shaped limiting rod 11 can limit the movement range of the connecting plate 12 to prevent the connecting plate 12 from falling off. With the cooperation of the baffle 5, the extension plate 8 and the connecting plate 12, the opening at the top of the tank 13 can be blocked during stirring to prevent solution splashing and affect the accuracy of subsequent experimental results. After stirring, the centrifugal force disappears, and the spring 7 can drive the extension plate 8 back into the baffle 5. The extension plate 8 squeezes the connecting plate 12, so that the connecting plate 12 enters the second limiting groove 10, thereby storing the connecting plate 12 and exposing the opening of the tank 13 for easy removal of the solution.

[0024] Please see Figure 1-5As shown, a connecting frame 17 is symmetrically arranged on the outer surface of the insulation layer 14. A first hinge rod is hinged to the connecting frame 17, and a hollow frame 18 is hinged to the first hinge rod. A positioning hole 19 is opened on the hollow frame 18. A reinforcing rod 20 is slidably connected inside the hollow frame 18. An elastic piece 21 is fixedly connected inside the reinforcing rod 20. A positioning block 22 is fixedly connected to the elastic piece 21. The positioning block 22 is movably connected inside the positioning hole 19. A second hinge rod is hinged to one end of the reinforcing rod 20. An anti-slip pad 23 is hinged to the second hinge rod.

[0025] Before stirring the solution, the hollow frames 18 on both sides are rotated outward about the first hinge rod as the axis. Then, the reinforcing rod 20 is pulled outward about the hollow frame 18, so that the positioning block 22 is located in the positioning hole 19 below the hollow frame 18. The pressure on the elastic piece 21 is reduced, which drives the positioning block 22 to move upward and enter the positioning hole 19, thereby fixing the position of the reinforcing rod 20. Then, the anti-slip pad 23 is rotated about the second hinge rod as the axis, so that the bottom of the anti-slip pad 23 is in contact with the table. This forms a triangle between the anti-slip pad 23, the table, the reinforcing rod 20, the hollow frame 18 and the insulation layer 14, which improves the support strength of the tank 13 and prevents the tank 13 from shaking during stirring, thereby preventing the tank 13 from falling.

[0026] Working principle: Before stirring the solution, the hollow frames 18 on both sides are rotated outward about the first hinge rod as the axis. Then, the reinforcing rod 20 is pulled outward from the hollow frame 18, so that the positioning block 22 is located in the positioning hole 19 below the hollow frame 18. The elastic plate 21 drives the positioning block 22 to move into the positioning hole 19. The anti-slip pad 23 is rotated about the second hinge rod as the axis, so that the bottom of the anti-slip pad 23 is in contact with the table. This forms a triangle between the anti-slip pad 23, the table, the reinforcing rod 20, the hollow frame 18, and the insulation layer 14, improving the support strength of the tank 13. The drive is then activated. Motor 2 drives stirring blades 4 and baffles 5 to rotate simultaneously via stirring rod 3. Stirring blades 4 stir the solution in tank 13. The centrifugal force generated when baffles 5 rotates throws extension plate 8 outward. When baffles 5 are thrown out, the surfaces that are in contact separate, so connecting plate 12 can block the gap between baffles 5. With the cooperation of baffles 5, extension plate 8 and connecting plate 12, the opening at the top of tank 13 can be blocked during stirring, thereby avoiding the accuracy of the final production data of chiral ester process due to solution splashing during stirring.
