Description

Technical Field

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

[0002] In the chemical production field, triallyl isocyanurate is an important organic synthesis intermediate widely used in polymer crosslinking, coatings, adhesives, and other industries. Its refining process is crucial for product purity and quality, and the heating process is one of the key factors affecting the refining effect.

[0003] Traditional triallyl isocyanurate refining equipment has several shortcomings in terms of heating. Common heating methods are mostly single external heating modes, such as directly heating the outer wall of the container through a heating jacket. This heating method is prone to uneven heating of the liquid inside the container, with the liquid temperature near the container wall rising faster. In addition, the outer wall of existing containers is generally planar, with a small heat exchange area, and the heat utilization rate needs to be improved. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a refining device for triallyl isocyanurate. During use, the device utilizes a sleeve in conjunction with heat-conducting oil to heat the internal liquid, and L-shaped and folded stirring rods further promote uniform heating of the liquid.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A purification apparatus for triallyl isocyanurate includes a housing with a drain port at the bottom and a feed port at the top; a stirring mechanism including a sleeve fixedly connected to the outside of the housing, an L-shaped frame fixedly connected to the upper end of the sleeve, a rotating tube vertically penetrating the horizontal portion of the L-shaped frame, the rotating tube being rotatably connected to the horizontal portion of the L-shaped frame via a bearing, the lower end of the rotating tube penetrating the upper end of the housing and extending into the interior of the housing, and multiple inclined stirring rods fixedly connected to the inner side wall of the rotating tube; and a heating mechanism located inside the sleeve.

[0007] Preferably, a sealing valve is installed at the drain port, a sealing cover is installed inside the feed port, and a connecting pipe is connected to the inner top space of the shell.

[0008] Preferably, the heating mechanism includes an electric heating ring installed at the bottom of the sleeve, the sleeve is filled with heat-conducting oil, and a plurality of L-shaped stirring rods are fixedly connected to the side wall of the rotating tube, the vertical parts of the plurality of L-shaped stirring rods extending into the interior of the heat-conducting oil.

[0009] Preferably, the inner sidewall of the housing is made of a thermally conductive material and has a wavy structure.

[0010] Preferably, a drive motor is installed at the upper end of the L-shaped frame, the output shaft of the drive motor passes through the L-shaped frame, and synchronous pulleys are installed on both the output shaft of the drive motor and the rotating tube, and the two synchronous pulleys are connected by a synchronous belt drive.

[0011] Preferably, the lower end of the rotating tube is sealed, and an air hole is provided on the side wall of the top space inside the housing.

A communication port is provided on the right side wall of the connecting cylinder. A fixing rod is fixedly connected to the left side of the piston rod, and the left end of the fixing rod extends to the outside and is fixedly connected to a load-bearing ball.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. The side wall of the shell inside the sleeve is made of thermally conductive material and has a corrugated shape to increase the actual heat exchange area.

[0014] 2. The drive motor drives the rotating tube to rotate via the synchronous pulley and synchronous belt. The inclined stirring rod stirs the liquid to be distilled, and the L-shaped stirring rod stirs the temperature-conducting oil, promoting uniform internal temperature of the liquid and temperature-conducting oil, avoiding local overheating, and improving the quality of the distilled product.

[0015] 3. Initially, the rotating tube is connected to the outside world through a connecting cylinder.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-4 A purification apparatus for triallyl isocyanurate includes a shell 1, a drain port 3 at the bottom of the shell 1, a feed port 7 at the top of the shell 1, a sealing valve installed at the drain port 3, a sealing cover installed inside the feed port 7, and a connecting pipe 8 connecting the top space of the shell 1. The other end of the connecting pipe 8 is connected to a vacuum negative pressure condensation system in the outside, which can ensure that the inside of the shell 1 is in a low-pressure state during distillation. The low pressure can lower the boiling point and promote the distillation process.

[0023] The device also includes a stirring mechanism, which includes a sleeve 2 fixedly connected to the outside of the housing 1. An L-shaped frame 4 is fixedly connected to the upper end of the sleeve 2. A rotating tube 6 is vertically installed through the horizontal part of the L-shaped frame 4. The rotating tube 6 is rotatably connected to the horizontal part of the L-shaped frame 4 through a bearing. The lower end of the rotating tube 6 passes through the upper end of the housing 1 and extends into the interior of the housing 1. A rotating sealing gasket is installed at the penetration point to ensure rotational sealing. Multiple inclined stirring rods 12 are fixedly connected to the side wall of the part of the rotating tube 6 inside the housing 1.

[0024] The system also includes a heating mechanism located inside the sleeve 2. The heating mechanism includes an electric heating ring 14 installed at the bottom of the sleeve 2. The sleeve 2 is filled with heat-conducting oil. Multiple L-shaped stirring rods 11 are fixedly connected to the side wall of the rotating tube 6. The vertical parts of the multiple L-shaped stirring rods 11 extend into the heat-conducting oil. The shell 1 is located inside the sleeve 2 and its side wall is made of heat-conducting material and has a wave-like structure. This structure can effectively increase the actual heat exchange area and improve the heat exchange effect. A drive motor 5 is installed at the upper end of the L-shaped frame 4. The output shaft of the drive motor 5 passes through the L-shaped frame 4. Both the output shaft of the drive motor 5 and the rotating tube 6 are equipped with synchronous pulleys 9. The two synchronous pulleys 9 are connected by a synchronous belt 10. When the drive motor 5 is started, the heat-conducting oil can be stirred by the L-shaped stirring rods 11. The rotation of the tilting stirring rod 12 can also be stirred to ensure temperature uniformity.

[0025] The lower end of the rotating tube 6 is sealed. An air hole 13 is provided on the side wall of the top space inside the housing 1. A connecting cylinder 15 is fixedly connected to the upper end of the rotating tube 6, communicating with the rotating tube 6. The right side of the connecting cylinder 15 is sealed, while the left side is open. A piston rod 16 that can slide left and right is installed inside the connecting cylinder 15. The right side of the piston rod 16 is elastically connected to the right side wall of the connecting cylinder 15 via a spring 17. A communication port 18 is provided on the right side wall of the connecting cylinder 15. The left side of the piston rod 16 is fixed... A fixed rod 19 is connected, with its left end extending to the outside and a load-bearing ball 20 fixedly connected. In the initial state, the piston rod 16 is located in the right space of the connecting cylinder 15. At this time, the rotating tube 6 communicates with the outside through the left space of the connecting cylinder 15. As the rotating tube 6 rotates, the connecting cylinder 15 can rotate. Under the action of centrifugal force, the load-bearing ball 20 moves away from the rotating tube 6, causing the spring 17 to stretch the piston rod 16 to move, sealing the connection between the rotating tube 6 and the connecting cylinder 15, ensuring the sealing performance of the device during use.

[0026] In this invention, the triallyl isocyanurate raw material is fed into the shell 1 through the feeding port 7, and then the sealing cover inside the feeding port 7 is closed to ensure that the shell 1 is sealed; at the same time, the sealing valve at the drain port 3 is kept closed.

[0027] The electric heating ring 14 installed at the bottom of the sleeve 2 is activated, heating the heat-conducting oil filled inside the sleeve 2. Since the side wall of the shell 1 inside the sleeve 2 is made of heat-conducting material and has a wavy structure, the actual heat exchange area is effectively increased. The heat-conducting oil quickly transfers heat to the interior of the shell 1, heating the triallyl isocyanurate to be distilled. The drive motor 5 installed on the upper end of the L-shaped frame 4 is activated. The output shaft of the drive motor 5 drives the rotating tube 6 to rotate via the synchronous pulley 9 and the synchronous belt 10. When the rotating tube 6 rotates, on the one hand, multiple inclined stirring rods 12 fixedly connected to the side wall of the rotating tube 6 located inside the shell 1 rotate accordingly, stirring the liquid to be distilled and ensuring uniform liquid temperature; on the other hand, the vertical parts of multiple L-shaped stirring rods 11 fixedly connected to the side wall of the rotating tube 6 stir inside the heat-conducting oil, promoting uniform temperature inside the oil and further improving the heat exchange effect.

[0028] Initially, the piston rod 16 is located in the right space of the connecting cylinder 15, and the rotating tube 6 is connected to the outside through the left space of the connecting cylinder 15. As the rotating tube 6 rotates, the connecting cylinder 15 also rotates. Under the action of centrifugal force, the load-bearing ball 20 moves away from the rotating tube 6, driving the piston rod 16 to move and stretching the spring 17 until the connection between the rotating tube 6 and the connecting cylinder 15 is sealed, ensuring the airtightness of the device during use.

[0029] Subsequently, the external vacuum negative pressure condensation system connected to the connecting pipe 8 is turned on, creating a low-pressure environment inside the shell 1. This low-pressure environment lowers the boiling point of triallyl isocyanurate, creating favorable conditions for the subsequent distillation process. After heating and stirring, the triallyl isocyanurate reaches its boiling point and begins distillation. The vapor enters the external vacuum negative pressure condensation system through the connecting pipe 8 for condensation and collection. After distillation is complete, the drive motor 5 is turned off. Under the elastic action of the spring 17, the piston column 16 moves back and is no longer at the upper end of the sealing rotating tube 6, thus balancing the gas pressure inside the shell 1. The sealing valve at the drain port 3 is then opened to discharge the remaining residue inside the shell 1.

[0030] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
