Description

Technical Field

[0001] This utility model relates to the field of guanidine hydrochloride production technology, and in particular to a screening device for industrial-grade guanidine hydrochloride production. Background Technology

[0002] In the production process of industrial-grade guanidine hydrochloride, due to the complexity of the raw material source and production process, the resulting product often has uneven particle size. In order to obtain guanidine hydrochloride products that meet specific specifications and quality standards, it is necessary to perform sieving to separate particles of different sizes, thereby meeting the needs of different application scenarios.

[0003] In practical applications, screening equipment for industrial-grade guanidine hydrochloride production typically requires the following technologies:

[0004] 1. Screening function, enabling the screening of materials;

[0005] 2. High screening efficiency, avoiding material accumulation and blockage.

[0006] Currently, traditional industrial-grade guanidine hydrochloride production screening devices suffer from insufficient screening accuracy, making it difficult to meet the requirements of multi-stage screening. They also have low screening efficiency, and materials tend to accumulate and clog the screen. Furthermore, it is difficult to remove the residual material from the screen, hindering subsequent screening. To address these issues, we propose an industrial-grade guanidine hydrochloride production screening device that offers high screening accuracy, high efficiency, and effective handling of residual materials.

[0015] (III) Beneficial Effects

[0016] The three-layer screen design with different apertures enables multi-stage fine screening of industrial-grade guanidine hydrochloride, greatly improving screening accuracy and precisely separating materials of different particle sizes to meet the demands of high-quality production. The cam-driven vibration mechanism, powered by a motor, effectively prevents material accumulation and clogging on the screens. Driven by the motor, the cam rotates continuously, causing the screening assembly, including the three screens, to move up and down and vibrate. This strong and uniform vibration facilitates rapid material passage through the screens, significantly improving screening efficiency. Simultaneously, this vibration method reduces the residence time of materials on the screens, lowering the possibility of material adhesion and agglomeration, further ensuring screening accuracy and stability, and providing strong support for continuous industrial production.

[0017] Second, the movement of the rectangular rod drives the movement of motor two, which in turn drives the movement of three threaded rods two. This drives the screening component to move up and down and vibrate, allowing materials of different particle sizes to be discharged through their respective discharge channels. This achieves rapid cleaning and discharge of residual materials on the screen. Baffles are fixedly installed on the upper and lower screens to block the chute, preventing materials from entering and ensuring the stability of the screening component's movement and vibration. The specially designed collection box has collection slots corresponding to different screens, which can classify and collect materials of different particle sizes for convenient subsequent processing and use. The collection box is fixed with bolts, ensuring the stability of the collection process and facilitating disassembly and cleaning when needed. Attached Figure Description

[0024] This application provides a screening device for industrial-grade guanidine hydrochloride production, effectively solving the problems of insufficient precision, low efficiency, and poor residual material handling in traditional screening devices. This industrial-grade guanidine hydrochloride production screening device features a three-layer screen design with different aperture sizes, enabling multi-stage fine screening of industrial-grade guanidine hydrochloride, greatly improving screening precision and accurately separating materials of different particle sizes to meet the demands of high-quality production. The cam-driven vibration method, powered by a motor, effectively prevents material accumulation and clogging on the screens. Driven by the motor, the cam rotates continuously, causing the screening assembly, including the three screens, to move up and down and vibrate. This strong and uniform vibration promotes rapid material passage through the screens, greatly improving screening efficiency. Simultaneously, this vibration method reduces the residence time of materials on the screens, decreasing material adhesion. The possibility of clumping and agglomeration further ensures the accuracy and stability of screening, providing a strong guarantee for continuous industrial production. The movement of the rectangular rod drives the movement of the second motor, which in turn drives the movement of the three threaded rods. At this time, the screening component moves up and down and vibrates, so that materials of different particle sizes are discharged through the corresponding discharge channels and outlets, realizing the rapid cleaning and discharge of residual materials on the screen. The baffles fixedly installed on the upper and lower screens act as a shield to prevent materials from entering the chute, ensuring the stability of the movement and vibration of the screening component. The specially designed collection box has collection slots corresponding to different screens inside, which can classify and collect materials of different particle sizes for convenient subsequent processing and use. The collection box is fixed with bolts, which not only ensures the stability of the collection process, but also makes it easy to disassemble and clean when needed.

[0025] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problems of insufficient accuracy, low efficiency, and poor handling of residual materials in traditional screening devices. The overall idea is as follows:

[0026] To address the problems existing in the prior art, this utility model provides a screening device for the production of industrial-grade guanidine hydrochloride, including a screening box 1. The screening box 1 has an inlet 11 at its upper end. A screening assembly 2 is installed inside the screening box 1, comprising three vertically distributed screens 21, each screen 21 being inclined. All three screens 21 are slidably installed inside the screening box 1. Sliding rods 22 are fixedly installed at both ends of each screen 21. Sliding grooves are formed on both sides of the inner wall of the screening box 1. Each sliding rod 22 is slidably installed in a sliding groove. A round rod 26 is fixedly installed in each sliding groove, and each round rod 26 movably passes through the sliding rod 22. A spring 27 is movably sleeved on each round rod 26. Each sliding rod 22 is connected to the upper side of the sliding groove via the spring 27. The inner wall is fixedly connected to a motor 3, which is fixedly connected to the output shaft of the motor 3. A threaded rod 31 is fixedly connected to the output shaft of the motor 3. A cam 32 for driving the vibration of the screening assembly 2 is fixedly installed on the threaded rod 31. Two baffles 23 are fixedly installed on the uppermost and lowermost screens 21. A connecting rod 24 is fixedly connected between the two baffles 23 on the lower side. A ball 25 is fixedly connected to the middle of the bottom end of the connecting rod 24. The protrusion of the cam 32 fits against the surface of the ball 25. Three discharge ports 12 are opened on the side surface of the screening box 1. A long plate 4 is provided at the outer end of the screening box 1. Three baffles 41 are fixedly installed on the long plate 4. Each baffle 41 is movably inserted into the discharge port 12. A rectangular rod is fixedly installed on the long plate 4. 6. A through rod 61 is fixedly connected to the rectangular rod 6. The through rod 61 is movably inserted into the screening box 1. A motor 5 is fixedly installed on the outer end of the screening box 1. A threaded rod 51 is fixedly connected to the output shaft of the motor 5. The threaded rod 51 passes through the through rod 61 and is threadedly connected to the through rod 61. Both the threaded rod 31 and the threaded rod 51 are rotatably installed in the screening box 1. A collection box 7 is provided at the three discharge ports 12. The collection box 7 is provided with three collection slots. Bolts are screwed into the collection box 7. The collection box 7 is connected and fixed to the screening box 1 by bolts. A discharge port 13 is opened on the lower side of the surface of the screening box 1. In use, the industrial grade guanidine hydrochloride to be screened is poured into the screening box 1 through the feed port 11. The motor 3 is started, which makes the threaded rod 31 rotate. The rotation of the threaded rod 31 drives the cam 32 to rotate. When the protrusion of the cam 32 contacts the ball 25, it applies an upward force to the ball 25, causing the screening assembly 2 to move upward. When the protrusion of the cam 32 is not in contact with the ball 25, the spring 27 resets the screening assembly 2. As the cam 32 continues to rotate, the screening assembly 2 moves up and down and vibrates. The aperture size of the three screens 21 gradually decreases from top to bottom. This screening device, by setting three layers of screens 21 with different aperture sizes, can achieve multi-stage screening of industrial-grade guanidine hydrochloride, improving screening accuracy. The cam 32 drives the screening assembly 2 to move up and down and vibrate, improving screening efficiency and preventing material accumulation and clogging on the screens 21.The screening box 1 has a discharge port 13 on its surface. The final screened material is discharged from the discharge port 13. When it is necessary to discharge the material remaining on each screen 21, the motor 25 is started, causing the threaded rod 251 to rotate. The rotation of the threaded rod 251 drives the through rod 61 and the rectangular rod 6 to move outward. The movement of the rectangular rod 6 drives the motor 25 to move. The movement of the motor 25 drives the three threaded rods 251 to move. At this time, the screening assembly 2 moves up and down and vibrates, so that materials of different particle sizes are discharged into the respective collection slots of the collection box 7 through the corresponding discharge channels 12. The baffles 23 fixedly installed on the upper and lower screens 21 block the chute, preventing materials from entering the chute and ensuring the stable movement and vibration operation of the screening assembly 2.

[0027] Working principle:

[0028] The first step, during use, is to pour the industrial-grade guanidine hydrochloride to be screened into the screening box 1 through the feed inlet 11. The motor 3 is started, causing the threaded rod 31 to rotate. The rotation of the threaded rod 31 drives the cam 32 to rotate. When the protrusion of the cam 32 contacts the ball 25, it applies an upward force to the ball 25, causing the screening assembly 2 to move upward. When the protrusion of the cam 32 is not in contact with the ball 25, the spring 27 resets the screening assembly 2. As the cam 32 continues to rotate... The movement causes the screening component 2 to move up and down and vibrate. The aperture size of the three screens 21 gradually decreases from top to bottom. By setting three layers of screens 21 with different aperture sizes, this screening device can achieve multi-stage screening of industrial-grade guanidine hydrochloride, improving screening accuracy. The cam 32 drives the screening component 2 to move up and down and vibrate, improving screening efficiency and preventing material from accumulating and clogging on the screens 21. The screening box 1 has a discharge port 13 on its surface, and the finally screened material is discharged from the discharge port 13.

[0029] The second step involves starting motor 5 to discharge the material remaining on each screen 21. This causes the threaded rod 51 to rotate, which in turn moves the through rod 61 and the rectangular rod 6 outward. The movement of the rectangular rod 6 then moves motor 5, which in turn moves the three threaded rods 51. This causes the screening assembly 2 to move up and down and vibrate, allowing materials of different particle sizes to be discharged through the corresponding discharge outlets 12 into the collection troughs of the collection box 7. The baffles 23 fixedly installed on the upper and lower screens 21 act as shields, preventing materials from entering the trough and ensuring the stable movement and vibration of the screening assembly 2.

[0030] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
