[0002] Flame retardant particles are one of the best flame retardant products in current plastics, rubber and other resins. Flame retardant particles (masterbatch) are obtained by organically combining, modifying and synergistically acting on various flame retardant components on the basis of flame retardants, and through a twin-screw or triple-screw extruder through mixing, extrusion and pelletizing to obtain a granular product; different from flame retardants, flame retardant particles have the advantages of being easy to add in resins, clean and hygienic, high flame retardant efficiency, small addition amount, little influence on the mechanical properties of resins, and not prone to occur stratification, patterns, precipitation and other adverse phenomena after addition, saving labor, material costs and time, etc.; generally speaking, the dispersibility, fluidity, compatibility with resins, thermal stability and weather resistance of flame retardant particles in resins are much better than ordinary flame retardants. In addition, the flame retardant efficiency and effectiveness (cost performance) of flame retardant particles with proper formulations are also much better than ordinary flame retardants.

Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the utility model.

[0030] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or position relationship are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation to the utility model.

[0031] Please refer to Figures 1-8 As shown in the figure, the present utility model is a flame-retardant plastic particle cleaning device, including a fixed seat 1. The top end of the fixed seat 1 is connected with a cleaning tank 4. The cleaning tank 4 is respectively provided with an adjustment component 2 and a transmission component 3. The front surface of the cleaning tank 4 is hinged with a sealing door through a hinge. The bottom end of the cleaning tank 4 is provided with a blanking port. The top end of the cleaning tank 4 is connected with a feeding hopper 5. The inner wall of one side of the cleaning tank 4 is connected with a guide plate 6. The inner side of the bottom end of the cleaning tank 4 is connected with two guide blocks 7. The other side of the cleaning tank 4 is connected with a drain pipe 8. The inner side of the drain pipe 8 is connected with a solenoid valve. The top end of the fixed seat 1 is connected with two guide rails 9. A collection shell 10 is placed between the two guide rails 9, and the collection shell 10 is located directly below the blanking port.

[0032] First, pour the flame-retardant plastic particles to be cleaned into the adjusting component 2 inside the cleaning tank 4 through the feeding hopper 5 and via the inclined guide plate 6. After pouring a batch, rotate the adjusting component 2 so that the adjusting component 2 combines to cover the flame-retardant plastic particles. Then, store clean water source into the inside of the cleaning tank 4 through the feeding hopper 5. Then, operate through the transmission component 3 to stir the flame-retardant plastic particles limited in the adjusting component 2 and wash them with clear water. After the washing is completed, control the water source to flow out of the inside of the cleaning tank 4 through the drain pipe 8 through the solenoid valve. Then, the staff only needs to open the sealed door of the cleaning tank 4 and rotate the adjusting component 2 to make the flame-retardant plastic particles fall into the lower collecting shell 10 through the adjusting component 2 and the discharge port opened on the cleaning tank 4. Finally, return the adjusting component 2 to its original position and close the sealed door to take away the collecting shell 10 containing the flame-retardant plastic particles. The operation is simple. It should be noted that for the sake of aesthetics and facilitating the observation of the adjusting component 2, the adjusting component 2 is not filled in some views. Actually, it is in a fine grid shape to hold the flame-retardant plastic particles to prevent them from falling.

[0033] The adjusting component 2 facilitates limiting the flame-retardant plastic particles in its internal space, preventing the situation of floating during the stirring and washing of the flame-retardant plastic particles, which affects the washing effect. The transmission component 3 facilitates stirring the flame-retardant plastic particles to increase the impact force between the flame-retardant plastic particles and the clear water, thereby improving the washing effect on the flame-retardant plastic particles. The drain pipe 8 facilitates draining the water after washing, and the collecting shell 10 facilitates collecting the washed flame-retardant plastic particles subsequently.

[0034] In one embodiment, for the above-mentioned adjusting component 2, the adjusting component 2 includes a connecting ring 21, a transfer ring 23 and two clamping plates 26. The connecting ring 21 is rotatably arranged on the inner wall of one side of the cleaning tank 4. One side of the connecting ring 21 is connected with a first retaining net 22.

A handle 28 is connected to the front of the sealing and intercepting plate 27.

[0035] First, pour the flame-retardant plastic particles to be cleaned into the connecting ring 21 inside the cleaning tank 4 through the feed hopper 5 and via the inclined guide plate 6. At this time, the first retaining net 22 is not merged with the second retaining net 25. After pouring a batch, rotate the second retaining net 25 to merge it with the first retaining net 22, that is, the transfer ring 23 and the clamping block 24 rotate inside the connecting ring 21, and the limiting effect of the clamping block 24 effectively prevents the transfer ring 23 from detaching from the inside of the connecting ring 21. Then, after rotating the second retaining net 25 to merge it with the first retaining net 22, the flame-retardant plastic particles are framed by the first retaining net 22 and the second retaining net 25, effectively preventing the flame-retardant plastic particles from floating when the cleaning tank 4 is filled with clean water. Next, fill the cleaning tank 4 with clean water source through the feed hopper 5, and then operate the transmission assembly 3 to stir the flame-retardant plastic particles limited by the first retaining net 22 and the second retaining net 25 and wash them with clean water. After the cleaning is completed, control the water source to flow out of the cleaning tank 4 through the drain pipe 8 by means of the solenoid valve. Then, the staff opens the sealed door of the cleaning tank 4 and holds the handle 28 to pull out the two clamping plates 26 and the sealed interceptor plate 27 outward, so that the material outlet is unobstructed. Finally, rotate the connecting ring 21 and the first retaining net 22, so as to drive the first retaining net 22 to rotate along the inner wall of the second retaining net 25, so that the flame-retardant plastic particles are poured out. The staff only needs to dial the flame-retardant plastic particles to make them completely detach from the second retaining net 25 and fall into the collection shell 10. The operation is simple. Finally, return the first retaining net 22, the second retaining net 25, the clamping plates 26 and the sealed interceptor plate 27, etc. to their positions and close the sealed door, then the collection shell 10 containing the flame-retardant plastic particles can be taken away. The operation is simple. It should be noted that for the sake of aesthetics and facilitating the observation of the first retaining net 22 and the second retaining net 25, the first retaining net 22 and the second retaining net 25 are not filled in some views. Actually, they are in the form of fine meshes to hold the flame-retardant plastic particles to prevent them from falling.

[0036] The first retaining net 22 and the second retaining net 25 that can rotate and limit each other are convenient to merge to cover the flame-retardant plastic particles, thus effectively preventing the flame-retardant plastic particles from floating when the cleaning tank 4 is filled with clean water, assisting in improving the cleaning effect. At the same time, it helps to separate and pour the washed flame-retardant plastic particles into the collection shell 10. By holding the handle 28, it is convenient to pull out the sealed interceptor plate 27, that is, it is convenient to pour the flame-retardant plastic particles into the collection shell 10 through the material outlet of the cleaning tank 4, facilitating the centralized extraction of the washed flame-retardant plastic particles. The transmission assembly 3 facilitates the stirring of the flame-retardant plastic particles in the first retaining net 22 and the second retaining net 25, enhancing the impact force between the flame-retardant plastic particles and the clean water, and thus helping to improve the cleaning effect.

[0037] In one embodiment, for the above-mentioned first netting 22, the bottom end of the first netting 22 is in contact with the inner side of the bottom end of the cleaning tank 4, and the surface of the clamping block 24 is slidably connected to the inner side of the connecting ring 21, thereby preventing the adapter ring 23 from detaching from the inside of the connecting ring 21.

[0038] In one embodiment, for the above-mentioned sealing and intercepting plate 27, the cross-sectional area of the sealing and intercepting plate 27 is larger than the cross-sectional area of the material discharging opening, and the bottom end of the sealing and intercepting plate 27 is in contact with the surface of the material discharging opening, which is conducive to taking out the flame-retardant plastic particles subsequently.

[0039] In one embodiment, for the above-mentioned transmission assembly 3, the transmission assembly 3 includes a driving source 31, a main bevel gear 33, a sub-bevel gear 34 and a wear-resistant rotating ring 36. The driving source 31 is arranged at the top end of the cleaning tank 4, and the power output end of the driving source 31 is power-connected to a connecting rod 32. The main bevel gear 33 is arranged at the bottom end of the connecting rod 32. The sub-bevel gear 34 is meshed with the main bevel gear 33. The inner side of the sub-bevel gear 34 is connected with a stirring rod 35. Both ends of the stirring rod 35 are rotatably connected to the inner wall of the cleaning tank 4 through bearings, and the surface of the stirring rod 35 is in contact with the surface of the connecting ring 21 and the surface of the second netting 25. The wear-resistant rotating ring 36 is arranged on the surface of the connecting rod 32, thereby facilitating the stirring of the flame-retardant plastic particles for cleaning.

[0040] In one embodiment, for the above-mentioned wear-resistant rotating ring 36, the surface of the wear-resistant rotating ring 36 is rotatably connected to the inner side of the top end of the cleaning tank 4, thereby avoiding the wear of the connecting rod 32 and further extending its service life.

[0041] In summary, by means of the above technical solution of the present utility model, first, the flame-retardant plastic particles to be cleaned are poured into the connecting ring 21 inside the cleaning tank 4 through the feed hopper 5 and via the inclined guide plate 6. At this time, the first retaining net 22 is not merged with the second retaining net 25. After pouring a batch, rotate the second retaining net 25 to merge it with the first retaining net 22, that is, the adapter ring 23 and the clamping block 24 rotate inside the connecting ring 21, and the limiting effect of the clamping block 24 effectively prevents the adapter ring 23 from detaching from the inside of the connecting ring 21. Then, after rotating the second retaining net 25 to merge it with the first retaining net 22, the flame-retardant plastic particles are framed by the first retaining net 22 and the second retaining net 25, effectively preventing the flame-retardant plastic particles from floating when the cleaning tank 4 is filled with clean water. Next, clean water source is filled into the cleaning tank 4 through the feed hopper 5, and then the driving source 31 drives the main bevel gear 33 and the auxiliary bevel gear 34 to rotate, which in turn drives the stirring rod 35 to rotate, stirring the flame-retardant plastic particles limited by the first retaining net 22 and the second retaining net 25 and cleaning them in cooperation with the clean water. After cleaning, control the water source to flow out of the inside of the cleaning tank 4 through the drain pipe 8 by means of the solenoid valve. Then, the staff opens the sealing door of the cleaning tank 4 and holds the handle 28 to pull out the two clamping plates 26 and the sealing intercepting plate 27 outward, so that the blanking port is no longer blocked. Finally, rotate the connecting ring 21 and the first retaining net 22, so as to drive the first retaining net 22 to rotate along the inner wall of the second retaining net 25, so that the flame-retardant plastic particles are poured out. The staff only needs to dial the flame-retardant plastic particles to make them completely detach from the second retaining net 25 and fall into the collection shell 10. The operation is simple. Finally, return the first retaining net 22, the second retaining net 25, the clamping plate 26, the sealing intercepting plate 27, etc. to their positions and close the sealing door, then the collection shell 10 containing the flame-retardant plastic particles can be taken away. The operation is simple. It should be noted that for the sake of aesthetics and facilitating the observation of the first retaining net 22 and the second retaining net 25, the first retaining net 22 and the second retaining net 25 are not filled in some views. Actually, they are in the form of fine meshes to hold the flame-retardant plastic particles to prevent them from falling.
