Description

Technical Field

[0001] This invention relates to the field of phosphate ester flame retardant production technology, specifically to a raw material impurity removal device used in the production of phosphate ester flame retardants. Background Technology

[0002] Phosphate ester flame retardants are a class of compounds that are added to materials to provide flame retardant properties. They are mainly produced by reacting the corresponding alcohol or phenol with phosphorus trichloride and then hydrolyzing it. Common phosphate ester flame retardants include tricresyl phosphate, triphenyl phosphate, triisopropylphenyl phosphate, tributyl phosphate, trioctyl phosphate, toluene diphenyl phosphate, etc. Phosphate ester flame retardants are diverse and have a wide range of applications. During the production of phosphate ester flame retardants, impurities in the raw materials need to be treated to avoid excessive impurities affecting the production quality of the flame retardant. A screening device is used to screen the phosphate ester flame retardant raw materials. The screening device uses vibration to block impurities in the flame retardant raw materials, allowing the impurities to be separated inside the screening device. However, some flame retardant raw materials may agglomerate together. Agglomerated flame retardant raw materials can easily encapsulate impurities, making it difficult to disperse them through vibration, thus affecting the screening efficiency of the screening device.

The gear passes through the cylindrical frame and extends into the interior of the cylindrical frame. The surface of the gear meshes with the surface of the toothed ring.

[0008] Furthermore, the agitating component includes bristles, the inner wall of which is fixedly connected to the surface of the curved rod, a fixing plate is fixedly connected to the surface of the curved rod, a striking plate is fixedly connected to the surface of the fixing plate, a connecting plate is fixedly connected to the surface of the curved rod, and an agitating plate is fixedly connected to the end of the connecting plate away from the curved rod. Both the rotating rod and the drive rod are fixedly connected to pulleys, and the inner walls of the two pulleys are connected to belts for transmission. The surface of the rotating rod is rotatably connected to the inner wall of the screening frame.

[0009] Furthermore, the fixed rod is located inside the screening frame, and four bending rods are arranged circumferentially around the fixed rod. The surface of the brush bristles contacts the inner wall of the screening frame. The end of the rotating rod passes through the screening frame and extends to the outer end of the cylindrical frame. The surface of the rotating rod is rotatably connected to the inner wall of the perforated plate. The striking plate is located at the end of the fixed plate near the fixed rod, and the surface of the stirring plate contacts the inner wall of the screening frame.

[0012] Furthermore, the feeding component includes a grooved plate, the surface of which is fixedly connected to the inner wall of the conical frame, and a cylindrical rod is fixedly connected to the end of the spring piece away from the circular plate, and the surface of the circular plate is fixedly connected to the end of the moving rod.

[0013] Furthermore, the surface of the circular plate is in contact with the inner wall of the feed tube, the circular plate is located at the end of the moving rod away from the adapter ring, and the end of the cylindrical rod away from the spring contact the inner wall of the groove plate.

[0014] The present invention has the following beneficial effects: This invention activates the hydraulic telescopic frame, pushing the limiting ring upwards. At this time, the end of the cylindrical frame furthest from the hydraulic telescopic frame rotates inside the support with the limiting ring as a fulcrum, allowing the conical frame to move upwards along with the rotation of the cylindrical frame. Then, the phosphate ester flame retardant raw material is added into the conical frame. The phosphate ester flame retardant raw material enters the screening frame through the feed pipe for screening. At this point, the hydraulic telescopic frame is activated, pushing the cylindrical frame back to its original position. The power unit is then activated, driving the drive rod to rotate. The gear, along with the rotation of the drive rod, drives the toothed ring to rotate. As the toothed ring rotates, it moves the screening frame in a circular motion. The internal rotation of the cylindrical frame causes the phosphate flame retardant raw material to rotate within it, thus screening the material. The rolling motion of the raw material prevents it from piling up and affecting screening efficiency. After screening, the material falls into the cylindrical frame and then enters the sliding plate through the discharge hole for centralized processing, improving the screening efficiency of the phosphate flame retardant raw material.

[0015] In this invention, the drive rod rotates via a pulley and belt, causing the rotating rod to rotate inside the screening frame. The rotating rod, in turn, drives the bending rod to rotate via a fixed rod. The bending rod, in turn, drives the brush bristles to rotate, cleaning the inner wall of the screening frame and preventing the phosphate flame retardant material from accumulating and affecting screening. The belt drives the rotating rod and drive rod to rotate in the same direction, while the gear, via a toothed ring, drives the screening frame and drive rod to rotate in opposite directions. At this time, the rotation direction of the brush bristles is opposite to that of the screening frame, increasing the friction between the bristles and the screening frame and improving the cleaning effect. Simultaneously, the bending rod, while rotating, drives the striking plate to rotate via a fixed plate. The striking plate, while rotating, strikes the phosphate flame retardant material with a counter-force, preventing the phosphate flame retardant material from agglomerating and encapsulating impurities, thus affecting the screening effect.

[0016] After the phosphate ester flame retardant raw material of this invention is screened, the hydraulic telescopic frame is activated to drive the cylindrical frame to rotate. When the unloading frame rotates to the bottom of the cylindrical frame, the electric actuator is activated to drive the moving rod to move. When the moving rod moves, it pushes and drives the sealing plate to the outer end of the unloading frame. At this time, the impurities in the screening frame will be discharged through the unloading frame, improving the convenience of impurity handling. At the same time, when the bending rod rotates, it will drive the stirring plate to rotate through the connecting plate. When the stirring plate rotates, it will push the impurities to move into the interior of the unloading frame, so that the impurities in the screening frame can quickly enter the interior of the unloading frame to complete the separation operation.

[0017] In this invention, after the phosphate flame retardant raw material is added into the conical frame, the electric actuator is activated to push the moving rod into the unloading frame. At this time, the sealing plate will seal the unloading frame. When the surface of the sealing plate aligns with the inner wall of the screening frame, the moving rod will push the circular plate to separate from the inner wall of the feed pipe and move into the conical frame. At this time, the phosphate flame retardant raw material inside the conical frame will fall into the screening frame. The electric actuator can push the moving rod to move back and forth. As the circular plate moves back and forth with the moving rod, it drives the cylindrical rod to move inside the grooved plate through the spring. At this time, the friction between the cylindrical rod and the grooved plate will generate vibration. The vibration can make the phosphate flame retardant raw material quickly enter the screening frame, avoiding the accumulation of phosphate flame retardant raw material inside the conical frame and affecting the feeding efficiency.

[0018] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The fixed rod 33 is located inside the screening frame 11. Four bending rods 34 are arranged circumferentially around the fixed rod 33. The rotation direction of the bristles 39 is opposite to that of the screening frame 11, which increases the friction between the bristles 39 and the screening frame 11 and improves the cleaning effect of the bristles 39 on the screening frame 11.

The telescopic end of the electric push rod 41 is fixedly connected to a moving rod 40. When the hydraulic telescopic frame 5 is activated, the cylindrical frame 10 is rotated. After the unloading frame 42 rotates to below the cylindrical frame 10, the electric push rod 41 is activated to push the moving rod 40 to move. The end of the moving rod 40 is fixedly connected to an adapter ring 47. The end of the unloading frame 42 is fixedly connected to the end of the screening frame 11 and communicates with the adapter hole 14. When the moving rod 40 moves, it pushes and drives the sealing plate 43 to move to the outer end of the unloading frame 42. At this time, the impurities in the screening frame 11 will be discharged through the unloading frame 42. The inner wall of the unloading frame 42 is slidably connected to the sealing plate 43.

[0030] The unloading rack 42 extends from the end away from the screening rack 11 to the outer end of the cylindrical rack 10. The unloading rack 42 is located at the end of the belt 31 near the cylindrical rack 10. At the same time, when the bending rod 34 rotates, it will drive the stirring plate 37 to rotate through the connecting plate 36. When the stirring plate 37 rotates, it will push impurities to move into the interior of the unloading rack 42. The end of the adapter ring 47 away from the moving rod 40 is rotatably connected to the inner wall of the circular groove ring 45.

The end of the spring piece 51 away from the circular plate 50 is fixedly connected to a cylindrical rod 52. At this time, the sealing plate 43 will seal the unloading frame 42. When the surface of the sealing plate 43 corresponds to the inner wall of the screening frame 11, the surface of the circular plate 50 is fixedly connected to the end of the moving rod 40.

[0032] The surface of the circular plate 50 is in contact with the inner wall of the feed pipe 19. The moving rod 40 will push the circular plate 50 to separate from the inner wall of the feed pipe 19 and move it into the interior of the conical frame 23. At this time, the phosphate ester flame retardant raw material inside the conical frame 23 will fall into the interior of the screening frame 11. The circular plate 50 is located at the end of the moving rod 40 away from the adapter ring 47, and the end of the cylindrical rod 52 away from the spring piece 51 is in contact with the inner wall of the groove plate 53.

[0033] In use, the hydraulic telescopic frame 5 is activated to push the limiting ring 12 upward. At this time, the end of the cylindrical frame 10 away from the hydraulic telescopic frame 5 will rotate inside the support 1 with the limiting ring 12 as the fulcrum, so that the conical frame 23 can move upward with the rotation of the cylindrical frame 10. At this time, after the phosphate flame retardant raw material is added into the inside of the conical frame 23, the phosphate flame retardant raw material will enter the inside of the screening frame 11 through the feed pipe 19 for screening. At this time, the hydraulic telescopic frame 5 is activated to push the cylindrical frame 10 to reset, and the power unit 20 is activated to drive the drive rod 22 to rotate. The gear 21 drives the toothed ring 16 to rotate with the rotation of the drive rod 22. When the toothed ring 16 rotates, it drives the screening frame 11 to rotate inside the cylindrical frame 10. When the screening frame 11 rotates, it drives the phosphate flame retardant raw material to rotate. The ester flame retardant raw material rotates inside the screening rack 11, which is used to screen the phosphate ester flame retardant raw material. The phosphate ester flame retardant raw material rolls inside the screening rack 11 to prevent it from piling up and affecting screening efficiency. After screening, the phosphate ester flame retardant raw material falls into the cylindrical frame 10 and enters the slide plate 3 through the discharge hole 15 for centralized processing. This centralized processing improves the screening efficiency of the screening rack 11. When the drive rod 22 rotates, it drives the rotating rod 32 to rotate inside the screening rack 11 via the connection between the pulley 30 and the belt 31. The rotating rod 32, in turn, drives the bending rod 34 to rotate via the fixed rod 33. When the bending rod 34 rotates, it drives the brush 39 to rotate, using the brush 39 to clean the inner wall of the screening frame 11, preventing the phosphate flame retardant raw material from accumulating on the inner wall of the screening frame 11 and affecting screening. The belt 31 drives the rotating rod 32 to rotate in the same direction as the drive rod 22, while the gear 21 drives the screening frame 11 and the drive rod 22 to rotate in opposite directions through the toothed ring 16. At this time, the rotation direction of the brush 39 is opposite to that of the screening frame 11, increasing the friction between the brush 39 and the screening frame 11 and improving the cleaning effect of the brush 39 on the screening frame 11. At the same time, when the bending rod 34 rotates, it drives the striking plate 35 to rotate through the fixed plate 38. When the striking plate 35 rotates, it strikes the phosphate flame retardant raw material with a force in the opposite direction, preventing... The phosphate ester flame retardant raw materials agglomerate and encapsulate impurities, affecting the screening effect. After the phosphate ester flame retardant raw materials are screened, the hydraulic telescopic frame 5 is activated to push the cylindrical frame 10 to rotate. When the unloading frame 42 rotates to below the cylindrical frame 10, the electric actuator 41 is activated to push the moving rod 40 to move. When the moving rod 40 moves, it pushes the sealing plate 43 to the outer end of the unloading frame 42. At this time, the impurities in the screening frame 11 will be discharged through the unloading frame 42, improving the convenience of impurity handling. At the same time, when the bending rod 34 rotates, it will drive the stirring plate 37 to rotate through the connecting plate 36. When the stirring plate 37 rotates, it will push the impurities to move into the interior of the unloading frame 42, so that the impurities in the screening frame 11 can quickly enter the interior of the unloading frame 42 to complete the separation operation.After the phosphate flame retardant raw material is added into the conical frame 23, the electric actuator 41 is activated to push the moving rod 40 into the unloading frame 42. At this time, the sealing plate 43 seals the unloading frame 42. When the surface of the sealing plate 43 aligns with the inner wall of the screening frame 11, the moving rod 40 pushes the circular plate 50 to separate from the inner wall of the feed pipe 19 and move it into the conical frame 23. At this time, the phosphate flame retardant raw material inside the conical frame 23 falls into the screening frame 11. The electric actuator 41 can push the moving rod 40 to move back and forth. As the circular plate 50 moves back and forth with the moving rod 40, the cylindrical rod 52 moves inside the grooved plate 53 through the spring piece 51. At this time, the friction between the cylindrical rod 52 and the grooved plate 53 generates vibration. The vibration allows the phosphate flame retardant raw material to quickly enter the screening frame 11, preventing the phosphate flame retardant raw material from accumulating inside the conical frame 23 and affecting the feeding efficiency.
