Description

Technical Field

[0001] This utility model relates to the field of thiadiazole preparation technology, and in particular to a thiadiazole preparation apparatus. Background Technology

[0002] Thiadiazole is a chemical substance that is typically synthesized through a concentrated reaction of reactants using a synthetic apparatus.

[0003] For example, the prior art, patent CN216778825U, discloses a reaction synthesis apparatus for preparing thiadiazole. This apparatus uses a motor to start the stirring assembly to stir the reaction inside the reaction shell, and can simultaneously feed materials through a hopper. The temperature inside the reaction shell is observed and displayed through a temperature reactor, making it more flexible to use. The heating plate heats and stores heat on the heat sink plate, and the heat sink plate is symmetrically arranged about the central axis of the reaction shell, thereby achieving the effect of heating and accelerating dissolution inside the reaction shell, making it more practical. The first stirring blades are evenly spaced on the outer surface of the first stirring rod. When the motor is started, the motor drives the first stirring rod to rotate, so that the first stirring blades rotate with the first stirring rod to stir the inside of the reaction shell. The second stirring rod is staggered with the first stirring blades, thereby increasing the stirring range and improving the reaction efficiency.

[0004] Although this device can improve the reaction efficiency to a certain extent, the heating components are only located on the inner side wall of the reaction shell. During the heating process of the reaction liquid, only the liquid inside the reaction shell near the shell can be heated, resulting in low heating efficiency and uneven heating, which affects the reaction efficiency. Therefore, a thiadiazole preparation device is designed to solve the above problems. Utility Model Content

An annular electric heating plate is fixedly installed in the center of the inner surface of the reaction cylinder. An electric heating plate is fixedly installed at the bottom center of the inner surface of the reaction cylinder. A temperature sensor is disposed through the left side of the bottom of the reaction cylinder.

[0008] Preferably, the power interface extends through the outer surface of the stirring shaft, and the horizontal height of the power interface is higher than the horizontal height of the upper surface of the reaction vessel.

[0009] Preferably, the stirring assembly includes a first stirring blade and a second stirring blade, and multiple first stirring blades are fixedly arranged on both the left and right surfaces of the stirring shaft, and multiple second stirring blades are fixed on both the upper and lower surfaces of the first stirring blades.

[0010] Preferably, the first stirring blade and the second stirring blade are arranged perpendicular to each other.

[0011] Preferably, a reaction solution circulation assembly is installed on the reaction cylinder and the stirring shaft. The circulation assembly includes a turntable fixed to the bottom of the stirring shaft and a one-way drain pipe penetrating the bottom right side of the reaction cylinder. The turntable is fixedly disposed at the bottom of the stirring shaft. A crank connecting rod is fixedly and rotatably disposed on the bottom of the turntable away from the center via a pin. A piston rod is rotatably disposed on the right end of the crank connecting rod. A piston is fixedly disposed on the right end of the piston rod. An inlet hole is penetrating the left side of the bottom surface of the one-way drain pipe. A one-way drain valve is fixedly disposed on the right side inside the one-way drain pipe. An inverted L-shaped reflux pipe is penetrating the right end of the one-way drain pipe. The top of the inverted L-shaped reflux pipe is disposed above the right side surface of the reaction cylinder. A drain valve is installed at the bottom of the inverted L-shaped reflux pipe.

[0012] Preferably, the piston is airtightly connected to the bottom of the inner surface of the one-way drain pipe, and when the crank connecting rod drives the piston to move to the left side of the inside of the one-way drain pipe, the piston is on the left side of the inlet hole; when the crank connecting rod drives the piston to move to the right side of the inside of the one-way drain pipe, the piston is on the right side of the inlet hole.

[0013] Preferably, when the crank connecting rod drives the piston to move to the inside left side of the one-way drain pipe, the piston will not disengage from the left end of the one-way drain pipe, and the one-way drain valve will come into contact with the piston when the crank connecting rod drives the piston to move to the inside left side of the one-way drain pipe.

[0014] Preferably, the liquid inlet is located inside the reaction cylinder.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] 1. This utility model, by incorporating an electric heating rod, an annular electric heating plate, and an electric heating disk, allows for the preparation of thiadiazole. Raw materials are added to the reaction chamber through a feed hopper. The electric heating rod is powered via a power plug, and the heat generated is transferred to a stirring shaft, which heats the reaction liquid in the center of the reaction chamber. The annular electric heating plate and electric heating disk, when powered on, generate heat to heat the reaction liquid near the side walls and bottom of the reaction chamber, respectively. This increases the heating rate of the reaction liquid inside the chamber and ensures uniform heating, thereby increasing synthesis efficiency. A temperature sensor detects and displays the temperature inside the reaction chamber, facilitating flexible operation by the operator. After preheating, the power plug is unplugged, and the annular electric heating plate and electric heating disk are turned on and off as needed to maintain the solution reaction temperature.

[0017] 2. This utility model is equipped with a stirring assembly. After the reaction solution is preheated, the motor is turned on to drive the stirring shaft to rotate. The stirring shaft drives the first stirring blade and the second stirring blade to rotate. The first stirring blade and the second stirring blade work together to stir the solution in the reaction cylinder, so that the reaction solution is mixed more evenly and the reaction rate is improved.

[0018] 3. This utility model incorporates a circulation component. When the motor drives the stirring shaft to rotate, it also drives the turntable to rotate. The rotation of the turntable, via the crank connecting rod, causes the piston rod and piston to move left and right along the one-way drainage pipe. When the piston moves to the left side of the inlet hole, the reaction liquid enters the one-way drainage pipe through the inlet hole. When the piston moves to the right side of the inlet hole, it squeezes and pushes the reaction liquid in the one-way drainage pipe on the right side of the inlet hole, and flows through the one-way drainage valve into the inverted L-shaped return pipe. The solution then flows through the inverted L-shaped return pipe to the top of the reaction cylinder and is discharged, achieving the effect of reaction liquid circulation. This further ensures the uniformity of the reaction liquid stirring and guarantees the reaction rate. When drainage is required, the drainage valve is opened, and the crank connecting rod drives the piston to move back and forth continuously, discharging the reacted solution from the one-way drainage pipe to the inverted L-shaped return pipe, and then out through the drainage valve.

[0026] Example:

[0027] like Figures 1-4 As shown, an embodiment of this utility model provides a thiadiazole preparation apparatus, including a reaction cylinder 1, a feed hopper 2, a support 3, a motor 4, and a stirring shaft 5. The feed hopper 2 is disposed through the left side of the upper surface of the reaction cylinder 1. The support 3 is fixedly installed in the center of the upper surface of the reaction cylinder 1. The motor 4 is installed above the support 3. The stirring shaft 5 is fixedly installed at the output end of the motor 4. An electric heating rod 501 is installed inside the stirring shaft 5. A power interface 502 is installed on the upper right side of the electric heating rod 501. A stirring assembly is installed on the stirring shaft 5. An annular electric heating plate 8 is fixedly installed in the center of the inner surface of the reaction cylinder 1. An electric heating plate 9 is fixedly installed at the bottom center of the inner surface of the reaction cylinder 1. A temperature sensor 10 is disposed through the left side of the bottom of the reaction cylinder 1.

[0028] Equipped with an electric heating rod 501, an annular electric heating plate 8, and an electric heating disk 9, the raw materials are added to the reaction cylinder 1 through the feed hopper 2 during the preparation of thiadiazole. The electric heating rod 501 is powered by the power plug inserted into the power interface 502. The heat generated by the electric heating rod 501 is transferred to the stirring shaft 5, which heats the reaction liquid in the center of the reaction cylinder 1. The annular electric heating plate 8 and the electric heating disk 9 are powered on and generate heat to heat the reaction liquid near the side wall and bottom of the reaction cylinder 1, respectively. This increases the heating rate of the reaction liquid inside the reaction cylinder 1 and ensures the uniformity of heating, thereby increasing the synthesis efficiency. The temperature inside the reaction cylinder 1 is sensed by the temperature sensor 10 and displayed for easy operation by the staff. After preheating, the power plug connected to the power interface 502 is unplugged, and the annular electric heating plate 8 and the electric heating disk 9 are turned on as needed to maintain the reaction temperature of the solution.

[0029] In this embodiment, the power interface 502 extends through the outer surface of the stirring shaft 5, and the horizontal height of the power interface 502 is higher than the horizontal height of the upper surface of the reaction vessel 1.

[0030] In this embodiment, the stirring assembly includes a first stirring blade 6 and a second stirring blade 7. Multiple first stirring blades 6 are fixedly arranged on both the left and right sides of the stirring shaft 5, and multiple second stirring blades 7 are fixed on both the upper and lower surfaces of the first stirring blades 6.

[0031] In this embodiment, the first stirring blade 6 and the second stirring blade 7 are arranged perpendicular to each other.

[0032] With the addition of a stirring assembly, after the reaction solution is preheated, the motor 4 is turned on, driving the stirring shaft 5 to rotate. The stirring shaft 5 drives the first stirring blade 6 and the second stirring blade 7 to rotate. The first stirring blade 6 and the second stirring blade 7 work together to stir the solution in the reaction cylinder 1, making the reaction solution more uniformly mixed and increasing the reaction rate.

[0033] In this embodiment, a reaction solution circulation assembly is installed on the reaction cylinder 1 and the stirring shaft 5. The circulation assembly includes a turntable 11 fixed to the bottom of the stirring shaft 5 and a one-way drain pipe 15 penetrating the bottom right side of the reaction cylinder 1. The turntable 11 is fixedly installed at the bottom of the stirring shaft 5. A crank connecting rod 12 is fixedly and rotatably installed at the bottom of the turntable 11 away from the center via a pin. A piston rod 13 is rotatably installed at the right end of the crank connecting rod 12. A piston 14 is fixedly installed at the right end of the piston rod 13. An inlet hole 16 is penetrating the left side of the bottom surface of the one-way drain pipe 15. A one-way drain valve 17 is fixedly installed on the right side of the inside of the one-way drain pipe 15. An inverted L-shaped return pipe 18 is penetrating the right end of the one-way drain pipe 15. The top of the inverted L-shaped return pipe 18 is penetrating above the right side surface of the reaction cylinder 1. A drain valve 19 is installed at the bottom of the inverted L-shaped return pipe 18.

[0034] In this embodiment, the piston 14 is airtightly connected to the bottom of the inner surface of the one-way drain pipe 15. When the crank connecting rod 12 moves the piston 14 to the left side of the inside of the one-way drain pipe 15, the piston 14 is on the left side of the inlet hole 16. When the crank connecting rod 12 moves the piston 14 to the right side of the inside of the one-way drain pipe 15, the piston 14 is on the right side of the inlet hole 16.

[0035] In this embodiment, when the crank connecting rod 12 drives the piston 14 to move to the left side inside the one-way drain pipe 15, the piston 14 will not disengage from the left end of the one-way drain pipe 15. When the crank connecting rod 12 drives the piston 14 to move to the left side inside the one-way drain pipe 15, it will contact the one-way drain valve 17.

[0036] Preferably, the liquid inlet 16 is located inside the reaction cylinder 1, so that the reaction liquid can enter the one-way drain pipe 15 through the liquid inlet 16.

[0037] With the circulation component, when the motor 4 drives the stirring shaft 5 to rotate, it will drive the turntable 11 to rotate. The rotation of the turntable 11 drives the piston rod 13 and piston 14 to move left and right along the one-way drain pipe 15 via the crank connecting rod 12. When the piston 14 moves to the left side of the inlet hole 16, the reaction liquid enters the one-way drain pipe 15 through the inlet hole 16. When the piston 14 moves to the right side of the inlet hole 16, it squeezes and pushes the reaction liquid in the one-way drain pipe 15 on the right side of the inlet hole 16 and flows into the inverted L-shaped return pipe 18 through the one-way drain valve 17. It then flows to the top of the reaction cylinder 1 through the inverted L-shaped return pipe 18 and is discharged, thus achieving the effect of reaction liquid circulation. This further ensures the uniformity of the reaction liquid stirring and the reaction rate. When it is necessary to discharge the liquid, the drain valve 19 is opened, and the crank connecting rod 12 drives the piston 14 to move back and forth continuously, discharging the reacted solution from the one-way drain pipe 15 to the inverted L-shaped return pipe 18, and then out through the drain valve 19.

[0038] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
