Description

Technical Field

[0001] This utility model belongs to the technical field of stirring devices, specifically an organic chemical raw material stirring device. Background Technology

[0002] Organic chemistry is a branch of chemistry that studies the sources, structures, properties, preparation, and uses of organic compounds. It focuses on the carbon atom as the core to study the structure and reactions of compounds. One type of plastic raw material in organic chemistry requires mixing of materials through stirring during its preparation.

[0003] The structure of plastic mixing equipment mainly includes a mixing container, a mixing shaft, mixing blades, a drive device, a sealing device, a control device, a feeding and discharging device, and a heating or cooling device. These components work together to achieve efficient mixing and stirring of plastic raw materials.

[0004] When using organic chemical raw materials for industrial production, it is necessary to put multiple raw materials into a reaction vessel and stir them to mix and react with each other to synthesize the desired substance. When adding raw materials into the reaction vessel, adding too much at once and adding too concentrated raw materials will increase the stirring resistance, which will lead to a decrease in the material flow rate and uneven distribution of reactant concentration, thus affecting the product yield and purity. Therefore, this utility model provides an organic chemical raw material stirring device. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: An organic chemical raw material stirring device of this utility model includes a support frame, a reaction vessel fixedly connected to the middle of the support frame, a discharge valve connected to the bottom of the reaction vessel, a cover plate installed on the top of the reaction vessel, multiple threaded holes opened in the middle of both the cover plate and the reaction vessel, and fastening screws threaded into the threaded holes. A first through hole is opened in the middle of the cover plate, and a crossbar fixedly connected to the first through hole. The crossbar has a triangular cross-section. A powder filling port is connected to the top of the first through hole. Multiple springs are fixedly connected to the bottom of the crossbar, and a dispersing disc is fixedly connected to the end of each spring. The surface is curved; by setting up a dispersion disk, the powdered raw material falls onto the crossbar and slides down along the side wall of the crossbar, eventually falling onto the dispersion disk. The top of the dispersion disk is curved, and the powdered raw material slides down the surface of the dispersion disk, thus dispersing the powdered raw material. When the powdered raw material falls onto the surface of the dispersion disk, the spring is stressed and expands, causing the dispersion disk to vibrate synchronously, which enhances the dispersion effect and makes the powdered raw material more evenly distributed when it falls into the reactor. This reduces the risk of adding too much raw material at once or adding it too concentratedly, which would increase the stirring resistance, thereby reducing the material flow rate and causing uneven distribution of reactant concentration, which in turn affects the product yield and purity.

[0007] Preferably, an annular water tank is fixedly connected to the bottom of the cover plate. The bottom of the annular water tank has multiple second through holes. A water pipe is connected to the top of the annular water tank through the cover plate. The top of the water pipe is connected to a liquid addition box. By providing the second through holes, liquid raw materials are added to the liquid addition box. The liquid raw materials flow into the annular water tank through the water pipe and then drip down through the multiple second through holes at the bottom of the annular water tank. The second through holes achieve the diversion of liquid raw materials, increase the dispersion of liquid raw materials, and reduce the problem of excessively strong reaction caused by excessive concentration of added liquid raw materials.

[0008] Preferably, a motor is fixedly connected to the top of the cover plate, and a rotating shaft is fixedly connected through the cover plate at the output end of the motor. Multiple stirring blades are fixedly connected to the middle of the rotating shaft. By setting the stirring blades, when the motor is started, the motor drives the rotating shaft to rotate, and the stirring blades rotate synchronously. The rotating stirring blades can stir the raw materials in the reactor, realizing the stirring process and making the raw materials evenly mixed.

[0009] Preferably, a scraper is fixedly connected to the end of the stirring fan blade, and the side wall of the scraper is in contact with the inner wall of the reactor. By providing a scraper, the movement of the stirring fan blade drives the scraper to move synchronously, and the scraper can scrape the inner wall of the reactor, reducing the problem of raw materials adhering to the inner wall of the reactor and making it difficult to clean.

[0010] Preferably, multiple turbine blades are fixedly connected to the middle of the rotating shaft, and the turbine blades are arranged in an array structure. By providing turbine blades, the rotating shaft drives the turbine blades to rotate synchronously. When the turbine blades rotate, they push the liquid raw material downwards and impact the powder raw material deposited at the bottom of the reactor. Combined with the lateral stirring of the stirring blades, the deposition of undissolved powder raw material at the bottom of the reactor can be reduced.

[0011] Preferably, a control box is installed on the top of the cover plate, and the control box is used to control the start and stop of the motor; by providing a control box, the control box can control the start and stop of the motor.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The organic chemical raw material stirring device of this utility model is equipped with a dispersion disc. Powdered raw materials fall onto the crossbar and slide down the side wall of the crossbar, eventually landing on the dispersion disc. The top of the dispersion disc is curved, allowing the powdered raw materials to slide down its surface. The dispersion disc disperses the powdered raw materials. When the powdered raw materials fall onto the surface of the dispersion disc, the spring is stressed and expands, causing the dispersion disc to vibrate synchronously, which enhances the dispersion effect and makes the powdered raw materials more evenly distributed when they fall into the reaction vessel. This reduces the risk of adding too much raw material at once or adding it too concentratedly, which would increase the stirring resistance, reduce the material flow rate, and cause uneven distribution of reactant concentration, thus affecting the product yield and purity.

[0014] 2. The organic chemical raw material stirring device of this utility model has a second through hole. The liquid raw material is added into the liquid addition box, and the liquid raw material flows into the annular water tank through the water pipe. Then, it drips down through multiple second through holes at the bottom of the annular water tank. The second through hole realizes the diversion of the liquid raw material, increases the degree of dispersion of the liquid raw material, and reduces the problem of excessive reaction caused by the addition of liquid raw material being too concentrated.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 4 , Figure 5 , Figure 6As shown, this utility model discloses an organic chemical raw material mixing device, including a support 11. A reaction vessel 12 is fixedly connected to the middle of the support 11. A discharge valve 101 is connected to the bottom of the reaction vessel 12. A cover plate 13 is installed on the top of the reaction vessel 12. Multiple threaded holes 14 are opened in the middle of both the cover plate 13 and the reaction vessel 12. Fastening screws 15 are threaded into the threaded holes 14. A first through hole 16 is opened in the middle of the cover plate 13. A crossbar 17 is fixedly connected in the first through hole 16. The crossbar 17 has a triangular cross section. The first through hole 16 is connected to a powder filling port 18 at its top. Multiple springs 19 are fixed to the bottom of the crossbar 17, and a dispersing disc 1 is fixed to the end of each spring 19. The top of the dispersing disc 1 is curved. In use, the cover plate 13 is placed on top of the reactor 12, aligning with the threaded holes 14 on the cover plate 13 and the reactor 12, and the fastening screws 15 are tightened. Powdered material is then added to the powder filling port 18. The powdered material falls downwards. The crossbar 17 has a triangular cross-section, and the powdered material falling onto the crossbar 17 will spread along the side wall of the crossbar 17. The powdered material slides downwards and eventually lands on the dispersion disk 1. The top of the dispersion disk 1 is curved, allowing the powdered material to slide down its surface. The dispersion disk 1 disperses the powdered material. When the powdered material falls onto the surface of the dispersion disk 1, the spring 19 contracts under pressure, causing the dispersion disk 1 to vibrate synchronously, enhancing the dispersion effect and making the powdered material more evenly distributed when it falls into the reaction vessel 12. With the dispersion disk 1 installed, the powdered material falling onto the crossbar 17 slides down its side wall and eventually lands on the dispersion disk 1. The top of the dispersion disk 1 is curved, and the powdered raw material will slide down along the surface of the dispersion disk 1. The dispersion disk 1 achieves the dispersion of the powdered raw material. When the powdered raw material falls onto the surface of the dispersion disk 1, the spring 19 will be stretched and contracted by the force, causing the dispersion disk 1 to shake synchronously, which enhances the dispersion effect and makes the powdered raw material more evenly distributed when it falls into the reaction vessel 12. This reduces the increase in stirring resistance caused by adding too much raw material at one time and adding too concentrated raw material, which leads to a decrease in material flow rate and uneven distribution of reactant concentration, thus affecting the product yield and purity.

The top of the water pipe 23 is connected to a liquid addition box 24. In use, liquid raw materials are added to the liquid addition box 24. The liquid raw materials flow into the annular water tank 21 through the water pipe 23, and then drip down through the multiple second through holes 2 at the bottom of the annular water tank 21. The second through holes 2 achieve diversion of the liquid raw materials, increasing the dispersion of the liquid raw materials and reducing the problem of excessively strong reactions caused by excessive concentration of added liquid raw materials. By providing the second through holes 2, liquid raw materials are added to the liquid addition box 24, and the liquid raw materials flow into the annular water tank 21 through the water pipe 23. Then, they drip down through the multiple second through holes 2 at the bottom of the annular water tank 21.

The output end of the motor 31 passes through the cover plate 13 and is fixedly connected to a rotating shaft 32. Multiple stirring blades 3 are fixedly connected to the middle of the rotating shaft 32. In use, the motor 31 is started, and the motor 31 drives the rotating shaft 32 to rotate. The stirring blades 3 rotate synchronously. The rotating stirring blades 3 can stir the raw materials in the reaction vessel 12, realizing the stirring process and making the raw materials evenly mixed. By setting the stirring blades 3, starting the motor 31, the motor 31 drives the rotating shaft 32 to rotate, and the stirring blades 3 rotate synchronously. The rotating stirring blades 3 can stir the raw materials in the reaction vessel 12, realizing the stirring process and making the raw materials evenly mixed.

[0027] like Figure 2 , Figure 3 As shown, a scraper 4 is fixedly connected to the end of the stirring blade 3, and the side wall of the scraper 4 is in contact with the inner wall of the reactor 12. In use, the movement of the stirring blade 3 drives the scraper 4 to move synchronously, and the scraper 4 can scrape the inner wall of the reactor 12, reducing the problem of raw materials adhering to the inner wall of the reactor 12 and making it difficult to clean.

[0028] like Figure 2 , Figure 3As shown, multiple turbine blades 5 are fixedly connected to the middle of the rotating shaft 32, and the turbine blades 5 are arranged in an array structure. In use, the rotating shaft 32 rotates, driving the turbine blades 5 to rotate synchronously. When the turbine blades 5 rotate, they push the liquid raw material downwards, impacting the powder raw material deposited at the bottom of the reactor 12. Combined with the lateral stirring of the stirring blades 3, this reduces the deposition of undissolved powder raw material at the bottom of the reactor 12. By setting up turbine blades 5, the rotating shaft 32 rotates, driving the turbine blades 5 to rotate synchronously.

The top of the dispersion plate 1 is curved, and the powdered raw material slides down along the surface of the dispersion plate 1. The dispersion plate 1 disperses the powdered raw material.

Add the liquid raw material into the liquid filling box 24. The liquid raw material flows into the annular water tank 21 through the water pipe 23, and then flows out from the bottom of the annular water tank 21. Multiple second through holes 2 are designed to drip downwards, which diverts the liquid raw materials, increases the dispersion of the liquid raw materials, and reduces the problem of excessive reaction caused by the addition of liquid raw materials being too concentrated. The motor 31 is started, which drives the rotating shaft 32 to rotate, and the stirring blades 3 rotate synchronously.
