Description

Technical Field

[0001] This utility model relates to the field of glycerol dehydration technology, specifically to a high-efficiency glycerol dehydration device. Background Technology

[0002] Glycerin, as an important chemical raw material, plays a crucial role in its dehydration process in industrial production. Glycerin dehydration aims to remove water from glycerin through specific technologies to improve its purity and quality.

[0003] A search revealed a Chinese patent document disclosing an aminoglycerol deamination and dehydration reactor [Announcement No.: CN216499255U]. This reactor includes a reactor body with a heating jacket outside. A separation chamber is located above the reactor body and is connected to it. A rotating shaft is rotatably connected inside the separation chamber, and multiple baffles are located on the side of the shaft. A motor is fixed outside the separation chamber and coaxially connected to the rotating shaft. An exhaust port is connected above the separation chamber. This invention utilizes the baffles on the arrayed rotating shaft in conjunction with a size-matched separation chamber. The baffles are driven to rotate by the motor, allowing vaporized water and ammonia to flow freely, while preventing aminoglycerol from splashing up due to boiling water from entering the pipeline through the baffles.

[0004] The most common dehydration equipment is a reaction vessel. By heating the reaction vessel, the water in the glycerol evaporates and is discharged, thus achieving the effect of dehydration. However, after the glycerol is heated, only the liquid surface is in contact with the air, which prevents the water vapor from being discharged quickly, thereby reducing the dehydration effect. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency glycerol dehydration device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency glycerol dehydration device, comprising a tank and a heating jacket, wherein the heating jacket is fixedly installed on the surface of the tank, a feed pipe is fixedly connected to the top of the tank, a discharge pipe is fixedly connected to the bottom of the tank, a stirring rod is provided inside the tank, a square frame is fixedly connected to the surface of the stirring rod, a piston box is fixedly connected to the top of the tank, a piston plate is slidably connected inside the piston box, an exhaust pipe is fixedly connected to the top of the piston box, and an air inlet pipe is fixedly connected to the top of the piston box;

[0007] A transmission mechanism is fixedly mounted on the top of the tank and can control the rotation of the stirring rod.

[0008] The exhaust mechanism is fixedly mounted on one side of the piston plate. When the transmission mechanism is running, it controls the piston plate to reciprocate.

[0009] Preferably, the transmission mechanism includes a bracket fixedly connected to the top of the tank, a motor fixedly installed on the inner wall of the bracket, a first transmission wheel fixedly connected to the output end of the motor, the top of the stirring rod extending through to the top of the tank and fixedly connected to a second transmission wheel, and the first transmission wheel and the second transmission wheel being connected by a belt drive.

[0010] Preferably, the exhaust mechanism includes a movable block fixedly connected to one side of the piston plate, a connecting rod fixedly connected to one side of the movable block, one end of the connecting rod extending through to one side of the piston box and fixedly connected to a transmission block, a transmission rod fixedly connected to the top of the second transmission wheel, and a transmission groove for cooperating with the transmission rod being opened on the top of the transmission block.

[0011] Preferably, a first one-way valve is fixedly connected to the surface of the intake pipe, and a second one-way valve is fixedly installed on the surface of the exhaust pipe.

[0012] Preferably, the top of the tank is provided with a connecting hole, and the inner wall of the connecting hole is fixedly connected with a sealing ring that works in conjunction with the stirring rod.

[0013] Preferably, the bottom of the stirring rod is provided with a bearing, and is fixedly connected to the inner wall of the tank through the bearing.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting up a transmission mechanism, enables the glycerin to be fed into the tank through the feed pipe, and then the tank to be heated by the heating jacket. After the glycerin is heated, the water contained inside will generate water vapor. At the same time, the motor is started, and the motor will drive the first transmission wheel to rotate. The first transmission wheel will drive the second transmission wheel to rotate through the belt. When the second transmission wheel rotates, the stirring rod will rotate synchronously with the second transmission wheel. The stirring rod will drive the square frame to rotate. Through stirring, the glycerin will form a vortex, thereby increasing the contact area between the glycerin and the air, promoting the formation of water vapor, and thus improving the dehydration effect of the glycerin.

[0016] 2. By setting up an exhaust mechanism, this utility model enables the transmission rod to rotate synchronously with the second transmission wheel as the second transmission wheel rotates. At the same time, the surface of the transmission rod will press against the inner wall of the transmission groove, causing the transmission block to move back and forth. The connecting rod, the moving block, and the piston plate will also move back and forth synchronously. When the piston plate moves to the left, the piston box is under negative pressure, and the water vapor in the tank will enter the interior of the piston box through the air inlet pipe. When the piston plate moves to the right, the water vapor in the piston box will be discharged through the exhaust pipe due to the compression. This cycle is repeated, effectively accelerating the discharge of water vapor and thus improving the dehydration efficiency. Attached Figure Description

[0024] 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 protection scope of the present utility model.

[0025] Please see Figure 1 - Figure 6 As shown, Example

[0026] A high-efficiency glycerol dehydration device includes a tank body 1 and a heating jacket 2. The heating jacket 2 is fixedly installed on the surface of the tank body 1. The top of the tank body 1 is fixedly connected to a feed pipe 3, and the bottom of the tank body 1 is fixedly connected to a discharge pipe 4. A stirring rod 5 is installed inside the tank body 1. A square frame 6 is fixedly connected to the surface of the stirring rod 5. A piston box 7 is fixedly connected to the top of the tank body 1. A piston plate 8 is slidably connected inside the piston box 7. An exhaust pipe 9 is fixedly connected to the top of the piston box 7, and an air inlet pipe 10 is fixedly connected to the top of the piston box 7.

[0027] The transmission mechanism is fixedly installed on the top of the tank 1 and can control the rotation of the stirring rod 5;

[0028] The exhaust mechanism is fixedly installed on one side of the piston plate 8. When the transmission mechanism is running, it controls the piston plate 8 to move back and forth.

[0029] The transmission mechanism includes a bracket 11 fixedly connected to the top of the tank 1. A motor 12 is fixedly installed on the inner wall of the bracket 11. A first transmission wheel 13 is fixedly connected to the output end of the motor 12. The top of the stirring rod 5 extends through to the top of the tank 1 and is fixedly connected to a second transmission wheel 14. The first transmission wheel 13 and the second transmission wheel 14 are connected by a belt 15.

[0030] In this embodiment, considering that after glycerin is heated, only the liquid surface is in contact with air, which prevents water vapor from being discharged quickly and reduces the dehydration effect, a transmission mechanism is set up. Glycerin is put into the tank 1 through the feed pipe 3, and then the tank 1 is heated by the heating jacket 2. After the glycerin is heated, the water contained inside will generate water vapor. At the same time, the motor 12 is started, which drives the first transmission wheel 13 to rotate. The first transmission wheel 13 drives the second transmission wheel 14 to rotate through the belt 15. When the second transmission wheel 14 rotates, the stirring rod 5 rotates synchronously with the second transmission wheel 14. The stirring rod 5 drives the square frame 6 to rotate. By stirring, the glycerin forms a vortex, thereby increasing the contact area between the glycerin and the air, promoting the formation of water vapor, and thus improving the dehydration effect of the glycerin.

[0031] The top of the tank 1 is provided with a connecting hole 23, and a sealing ring 24 that works with the stirring rod 5 is fixedly connected to the inner wall of the connecting hole 23.

[0032] In this embodiment, by providing a connecting hole 23 and a sealing ring 24, space can be provided for the stirring rod 5 to rotate. At the same time, the sealing ring 24 can prevent glycerin from leaking from the connecting hole 23 by sealing.

[0033] The bottom of the stirring rod 5 is provided with a bearing 25, and is fixedly connected to the inner wall of the tank 1 through the bearing 25.

[0034] In this embodiment, by setting the bearing 25, the structure such as the stirring rod 5 can be supported, and the smoothness of its rotation process can be improved. Example

[0035] Based on Embodiment 1, in this embodiment, the stirring rod 5 and the square frame 6 are driven by the transmission mechanism to stir the glycerin, thereby increasing the contact area between the glycerin and the air, promoting the generation of water vapor, and thus improving the dehydration effect. However, considering that if the large amount of water vapor is not discharged from the tank 1 in time, it will condense into water droplets and fall back into the glycerin, thereby reducing the dehydration efficiency, the exhaust mechanism in this application includes a moving block 16 fixedly connected to one side of the piston plate 8. A connecting rod 17 is fixedly connected to one side of the moving block 16. One end of the connecting rod 17 extends through to one side of the piston box 7 and is fixedly connected to a transmission block 18. A transmission rod 19 is fixedly connected to the top of the second transmission wheel 14. A transmission groove 20 that cooperates with the transmission rod 19 is opened on the top of the transmission block 18.

[0036] In this embodiment, by providing an exhaust mechanism, it is possible to provide airflow while the second transmission wheel 14 is rotating. Figure 6 As shown, the transmission rod 19 rotates synchronously with the second transmission wheel 14. At the same time, the surface of the transmission rod 19 presses against the inner wall of the transmission groove 20, causing the transmission block 18 to move back and forth. The connecting rod 17, the moving block 16, and the piston plate 8 also move back and forth synchronously. When the piston plate 8 moves to the left, the piston box 7 is under negative pressure, and the water vapor in the tank 1 enters the interior of the piston box 7 through the air inlet pipe 10. When the piston plate 8 moves to the right, the water vapor in the piston box 7 is discharged through the exhaust pipe 9 due to the compression. This cycle is repeated, effectively accelerating the discharge of water vapor and thus improving the dehydration efficiency.

[0037] It should be noted that, Figure 6 S1 is the movement trajectory of the transmission rod 19, and S2 is the movement trajectory of the transmission block 18.

[0038] A first one-way valve 21 is fixedly connected to the surface of the intake pipe 10, and a second one-way valve 22 is fixedly installed on the surface of the exhaust pipe 9.

[0039] In this embodiment, a first one-way valve 21 and a second one-way valve 22 are provided. The first one-way valve 21 is a valve that can only allow air to enter the piston box 7, and the second one-way valve 22 is a valve that can only allow air to be discharged from the piston box 7. Therefore, when there is a negative pressure in the piston box 7, the water vapor in the tank 1 can only enter the piston box 7 through the air inlet pipe 10. When the water vapor in the tank 1 is compressed, the water vapor can only be discharged through the exhaust pipe 9.

[0040] Working principle: The user puts glycerin into the tank 1 through the feed pipe 3, and then heats the tank 1 through the heating jacket 2. After the glycerin is heated, the water contained inside will generate water vapor. At the same time, the motor 12 is started, which drives the first transmission wheel 13 to rotate. The first transmission wheel 13 drives the second transmission wheel 14 to rotate through the belt 15. When the second transmission wheel 14 rotates, the stirring rod 5 rotates synchronously with the second transmission wheel 14. The stirring rod 5 drives the square frame 6 to rotate. Through stirring, the glycerin forms a vortex, thereby increasing the contact area between the glycerin and the air, promoting the formation of water vapor, and thus improving the dehydration effect of the glycerin.

[0041] As the second transmission wheel 14 rotates, reference Figure 4 As shown, the transmission rod 19 rotates synchronously with the second transmission wheel 14. At the same time, the surface of the transmission rod 19 presses against the inner wall of the transmission groove 20, causing the transmission block 18 to move back and forth. The connecting rod 17, the moving block 16, and the piston plate 8 also move back and forth synchronously. When the piston plate 8 moves to the left, the piston box 7 is under negative pressure, and the water vapor in the tank 1 enters the interior of the piston box 7 through the air inlet pipe 10. When the piston plate 8 moves to the right, the water vapor in the piston box 7 is discharged through the exhaust pipe 9 due to the compression. This cycle is repeated, effectively accelerating the discharge of water vapor and thus improving the dehydration efficiency.

[0042] It should be noted that the heating sleeve 2 and the motor 12 are existing devices or equipment, or devices or equipment that can be implemented by existing technology, and the specific composition and principle of the power supply of the heating sleeve 2 and the motor 12 are clear to those skilled in the art, so they will not be described in detail here.
