Abstract
Description
Technical Field
[0001] This application relates to the field of chemical raw material screening equipment, and in particular to a rapid screening mechanism for chemical raw material mixtures. Background Technology
[0002] In the synthesis of pesticide chemical products such as thiamethoxam, the mixing and processing of various solid raw materials are often involved. These raw materials often contain particles of different sizes. When screening such raw materials, fine particles easily clog the screen mesh of existing vibrating screens, leading to a decrease in screening efficiency and even affecting the screening quality. Moreover, when the screen mesh is clogged, manual cleaning is usually required, which not only increases labor intensity but also reduces production efficiency. In addition, the existing screening mechanisms have relatively simple screen cleaning methods, and the cleaning effect is not ideal. Utility Model Content
[0003] This application provides a rapid screening mechanism for chemical raw material mixtures. The screening barrel is equipped with a cleaning mechanism. In the synthesis process of pesticide chemical products such as thiamethoxam, by setting up a liftable cleaning mechanism on the outer and inner cylinders, the cleaning mechanism can be periodically lowered to clean each screen, avoiding screen mesh blockage and affecting the screening effect. Compared with the traditional screening mechanism that requires manual cleaning by stopping the machine, this reduces labor intensity, reduces cleaning time, and improves production efficiency. The cleaning brush rotates under the drive of the rotating shaft to mechanically clean the particles attached to the screen surface, and the air nozzle sprays gas to blow the screen. The combination of mechanical cleaning and airflow cleaning works together to remove the material adhering to the screen, effectively solving the problem of mesh blockage and improving cleaning efficiency and effect.
[0004] This application provides a rapid screening mechanism for chemical raw material mixtures, comprising: a barrel body, a vibration motor installed at the bottom of the barrel body, four support legs welded to the outer wall of the barrel body, a first screen, a second screen and a third screen arranged sequentially from top to bottom inside the barrel body, a first discharge port, a second discharge port, a third discharge port and a fourth discharge port arranged on the side wall of the barrel body corresponding to the first screen, the second screen, the third screen and the bottom, a rotating shaft movably installed at the bottom of the barrel body, a servo motor connected to the bottom of the rotating shaft, the rotating shaft including an outer cylinder and an inner cylinder, the inner cylinder being movably fitted inside the outer cylinder, a cleaning mechanism corresponding to each screen being arranged on the rotating shaft, each cleaning mechanism including a frame, a cleaning brush and an air pipe, multiple air nozzles being provided on the air pipe, three rectangular holes for the frame to pass through the side wall of the outer cylinder, three frames being welded to the side wall of the inner cylinder, a cleaning brush being installed at the bottom of the frame, the air pipe being fixed on the frame with the air nozzles facing the screen, a main pipe connected to each air pipe being provided inside the inner cylinder, the main pipe being connected to an external air compressor, and a lifting limit structure being provided between the inner cylinder and the outer cylinder;
[0005] The barrel is connected to a controller, and the vibration motor, servo motor, and air compressor are electrically connected to the controller.
[0006] Furthermore, the aperture diameter of the first screen is larger than that of the second screen, and the aperture diameter of the second screen is larger than that of the third screen.
[0007] Furthermore, each screen has a bearing seat 1 installed in the center, and bearing seats 2 are installed in the center of the bottom and top of the barrel, with the rotating shaft passing through several bearing seats.
[0008] Furthermore, a spring is installed at the bottom of the outer cylinder, and the top of the spring is connected to the bottom of the inner cylinder.
[0009] Furthermore, the lifting and limiting structure includes an L-shaped hole on the top side wall of the outer cylinder and a locking post welded to the corresponding position of the inner cylinder, with the locking post engaging with the L-shaped hole.
[0010] Furthermore, the controller is equipped with several operation buttons.
[0011] As can be seen from the above technical solution, this application provides a rapid screening mechanism for chemical raw material mixtures, including: a barrel body, a vibration motor installed at the bottom of the barrel body, four support legs welded to the outer wall of the barrel body, a first screen, a second screen, and a third screen arranged sequentially from top to bottom inside the barrel body, a first discharge port, a second discharge port, a third discharge port, and a fourth discharge port arranged on the side wall of the barrel body corresponding to the first screen, the second screen, the third screen, and the bottom, a rotating shaft movably installed at the bottom of the barrel body, a servo motor connected to the bottom of the rotating shaft, the rotating shaft including an outer cylinder and an inner cylinder, the inner cylinder being movably fitted inside the outer cylinder, a cleaning mechanism corresponding to each screen being arranged on the rotating shaft, each cleaning mechanism including a frame, a cleaning brush, and an air pipe, multiple air nozzles being provided on the air pipe, three rectangular holes for the frames to pass through the side wall of the outer cylinder, three frames being welded to the side wall of the inner cylinder, a cleaning brush being installed at the bottom of the frame, the air pipe being fixed to the frame with the air nozzles facing the screen, a main pipe connected to each air pipe being provided inside the inner cylinder, the main pipe being connected to an external air compressor, the inner cylinder and the outer cylinder being connected to the outer cylinder. The system features a lifting and limiting structure between the drums, and a controller is connected to the outside of the drum. A vibration motor, servo motor, and air compressor are electrically connected to the controller. The chemical raw material mixture to be screened is fed into the drum through the inlet. The controller then activates the vibration motor, causing the drum to vibrate. The chemical raw material mixture vibrates and is screened on the screens. Multiple screens are used to separate the chemical raw materials into different particle sizes. After a period of screening, a cleaning mechanism descends to clean each screen, preventing clogging and ensuring optimal screening results. When the cleaning mechanism reaches a designated position, the cleaning brush contacts the screen, activating the servo motor and air compressor. The cleaning brush rotates on the shaft, mechanically cleaning the particles adhering to the screen surface. Air jets from nozzles blow air across the screen.

Detailed Implementation
[0025] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.
[0026] As can be seen from the above technical solutions, see [link / reference]. Figures 1-7 .
[0027] Example 1:
[0028] A rapid screening mechanism for chemical raw material mixtures includes: a barrel body 1, a vibrating motor 6 installed at the bottom of the barrel body 1, and four support legs 5 welded to the outer wall of the barrel body 1, which support the barrel body 1. Each support leg 5 has a spring column in the middle to facilitate the vibration of the vibrating motor 6, which drives the barrel body 1 to vibrate and screen the material. Inside the barrel body 1, from top to bottom, are arranged a first screen 2, a second screen 3, and a third screen 4. Corresponding to the first screen 2, second screen 3, third screen 4, and bottom of the barrel body 1, there are a first discharge port 7, a second discharge port 8, a third discharge port 9, and a fourth discharge port 10. The pesticide chemical raw material mixture to be screened is fed into the barrel body 1 through the inlet, and then the vibrating motor 6 is started by the controller 25, causing the barrel body 1 to vibrate. The raw material mixture begins to be vibrated and screened on a screen. Under the vibration, the raw materials are rapidly dispersed and move on the first screen 2. Particles larger than the aperture of the first screen 2 are trapped on the first screen 2 and collected from the first outlet 7. Particles smaller than the aperture of the first screen 2 fall onto the second screen 3. Similarly, after being screened by the second screen 3, the raw materials that meet the particle size requirements are collected from the second outlet 8. The remaining raw materials fall onto the third screen 4. After being screened by the third screen 4, the raw materials that meet the particle size requirements are collected from the third outlet 9. The finest raw materials fall to the bottom of the barrel 1 and are collected from the fourth outlet 10. Through multi-stage screening, the chemical raw material mixture is collected and separated into chemical particles of different sizes. Raw materials are readily available for later use. At this time, the cleaning mechanism 15 is in a high position under the support of the spring 16, with the cleaning brush and air nozzle 18 far from the screen, not affecting normal screening. A rotating shaft is movably installed at the bottom of the barrel 1, with a servo motor 12 connected to the bottom of the shaft. The rotating shaft includes an outer cylinder 11 and an inner cylinder 13, with the inner cylinder 13 movably fitted inside the outer cylinder 11. A pressure plate is installed at the top of the inner cylinder 13. Cleaning mechanisms 15 corresponding to each screen are installed on the rotating shaft. The cleaning mechanism 15 can be periodically controlled to descend and clean each screen, preventing the screen holes from being blocked and affecting the screening effect. Compared to traditional screening mechanisms that require manual cleaning by stopping the machine, this reduces labor intensity, cleaning time, and increases production efficiency. Each cleaning mechanism 15 includes a frame, a cleaning brush, and an air pipe 17. The air pipe 17 is equipped with multiple air nozzles 18. Three rectangular holes 14 are opened on the side wall of the outer cylinder 11 for the frames to pass through. Three frames are welded to the side wall of the inner cylinder 13. A cleaning brush is installed at the bottom of the frames. The air pipe 17 is fixed to the frames with the air nozzles 18 facing the screen. A main pipe 24 communicating with each air pipe 17 is located inside the inner cylinder 13. Both the air pipes 17 and the main pipe 24 are flexible hoses. A rotary joint 23 is installed at the bend of the main pipe 24 located at the top of the rotating shaft. The rotary joint 23 allows the front end of the main pipe 24 (located inside the inner cylinder 13) to rotate with the rotating shaft without affecting the rear end of the main pipe 24 (outside the inner cylinder 13). The main pipe 24 is connected to an external air compressor 22. A dryer filter is installed between the main pipe 24 and the air compressor 22 to remove moisture from the air.To prevent the raw materials to be screened from getting damp, a lifting and limiting structure is provided between the inner cylinder 13 and the outer cylinder 11. After screening for a period of time, the controller 25 controls the vibration motor 6 to stop working, and the operator manually presses the pressure plate at the top of the rotating shaft. The locking post 20 on the side wall of the inner cylinder 13 slides down and locks in the end limiting position within the L-shaped hole 21. The inner cylinder 13 moves downward relative to the outer cylinder 11. At this time, the cleaning mechanism 15 on the rotating shaft moves downward with the inner cylinder within the rectangular hole 14. The frame on the side wall of the inner cylinder 13 moves down, causing the cleaning brush to contact the corresponding screen surface. The controller 25 controls the servo motor 12 and the air compressor 22 to start. Driven by the servo motor 12, the rotating shaft drives the cleaning brush to rotate slowly. The cleaning brush mechanically cleans the screen surface. Air compressor 22 generates gas that flows through main pipe 24 and air pipe 17, and is ejected from air nozzle 18 to blow air across the screen. The two work together to remove material adhering to the screen, effectively solving the problem of screen hole blockage and improving cleaning efficiency and effect. After cleaning, controller 25 shuts down servo motor 12 and air compressor 22. Then, the inner cylinder 13 is manually rotated, causing the locking pin 20 to move away from its limit position and rise. Under the elastic action of spring 16 at the bottom of the inner cylinder 13, the inner cylinder 13 returns to its original position, the cleaning mechanism rises and resets, the cleaning brush separates from the screen, and the vibrating motor 6 is restarted via controller 25 to continue the screening process.
[0029] A controller 25 is connected to the outside of the barrel 1. The vibration motor 6, servo motor 12, and air compressor 22 are electrically connected to the controller 25. The controller 25 controls the working status of the vibration motor 6, servo motor 12, and air compressor 22, thereby ensuring the smooth screening and cleaning of the barrel 1.
[0030] In a preferred embodiment, the aperture of the first screen 2 is larger than that of the second screen 3, the aperture of the second screen 3 is larger than that of the third screen 4, and the aperture of each screen decreases sequentially, so as to perform multi-stage screening of the mixture of chemical raw materials.
[0031] In a preferred embodiment, a bearing seat 19 is installed in the center of each screen, and bearing seats 2 are installed in the center of the bottom and top of the barrel 1, respectively. The rotating shaft passes through several bearing seats, and the rotation of the rotating shaft in each bearing seat does not affect the screen.
[0032] In a preferred embodiment, a spring 16 is provided at the bottom of the outer cylinder 11. The top of the spring 16 is connected to the bottom of the inner cylinder 13. After the cleaning mechanism 15 finishes cleaning, the elastic action of the spring 16 assists the inner cylinder 13 to move upward and reset, so that the cleaning mechanism 15 can move upward and reset to continue the screening work.
[0033] As a preferred embodiment, the lifting and limiting structure includes an L-shaped hole 21 disposed on the top side wall of the outer cylinder 11 and a locking post 20 welded to the corresponding position of the inner cylinder 13. The locking post 20 is engaged in the L-shaped hole 21, and the locking post 20 can be manually controlled to move up and down in the L-shaped hole 21, thereby limiting the lifting stroke of the inner cylinder 13 and thus limiting the lifting trajectory of the cleaning mechanism 15.
[0034] In a preferred embodiment, the controller 25 is provided with a number of operation buttons, which respectively control the on / off state of the vibration motor 6, the servo motor 12, and the air compressor 22.
[0035] Working principle:
[0036] The chemical raw material mixture to be screened is fed into the barrel 1 through the feed inlet. Then, the vibration motor 6 is started by the controller 25 to make the barrel 1 vibrate. The chemical raw material mixture begins to vibrate and screen on the screen. The chemical raw material mixture is screened and collected through multiple screens, thus separating chemical raw materials of different particle sizes for later use. After screening for a period of time, the cleaning mechanism 15 is controlled to descend and clean each screen to prevent the screen holes from being blocked and affecting the screening effect. When the cleaning mechanism 15 descends to the designated position, the cleaning brush contacts the screen. The controller 25 controls the servo motor 12 and the air compressor 22 to start. The cleaning brush rotates under the drive of the shaft to mechanically clean the particles attached to the screen surface. The air nozzle 18 sprays air to blow the screen. The combination of mechanical cleaning and air cleaning works together to remove the material adhering to the screen, effectively solving the problem of screen hole blockage and improving cleaning efficiency and effect.
