[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0026] like Figures 1 to 5As shown, a cleaning device for functional plastic masterbatch comprises a cleaning tank 1 and a spiral slide 3 sleeved on the outer wall of the cleaning tank 1. A feed port is provided on the top of the cleaning tank 1 and is used in conjunction with a conventional masterbatch conveying device to achieve continuous feeding. A water inlet pipe is provided at the edge of the top of the cleaning tank 1. A water filter slide 8 and a material discharge slide 9 are provided inside the spiral slide 3 along its spiral direction. The water filter slide 8 and the material discharge slide 9 divide the inside of the spiral slide 3 into two upper and lower spiral slides. The upper and lower slides convey masterbatch and water respectively. The bottom end of the spiral slide 3 is fixedly installed A purified water tank 4 is installed, and the bottom end of the unloading chute 9 passes through the bottom end of the spiral chute 3 and the top of the purified water tank 4 in sequence and extends to the outside of the purified water tank 4. A return pipe 5 is installed on the side of the outer wall of the purified water tank 4 away from the cleaning tank 1. The top of the return pipe 5 is fixedly connected to one side wall of the cleaning tank 1. A hot air blower 6 is installed on the top of the cleaning tank 1. An air duct 7 is installed at the air outlet of the hot air blower 6. The high-temperature airflow generated by the hot air blower 6 will be blown into the interior of the spiral chute 3 through the air duct 7, and blown out from the top of the interior to the bottom of the interior, and cooperate with the spiral chute 3 to accelerate the masterbatch. The material discharge speed is increased. At the same time, the spiral slide 3 cooperates with the water filtering slide 8, the material discharge slide 9 and the high-temperature airflow, so that the masterbatch and water can be separated inside the spiral slide 3, and the high-temperature airflow can dry the water adhering to the surface of the masterbatch, and blow the water vapor away from the inside of the spiral slide 3, so that the masterbatch can be drained, dried and discharged during the sliding process inside the spiral slide 3. At the same time, the separated water will be transported to the inside of the purified water tank 4, and the impurities in the water will be filtered out through precipitation, and then the purified water will enter the cleaning tank 1 again through the reflux of water, which is effective. In order to reuse water resources, the bottom end of the air guide 7 is sleeved on the top of the spiral slide 3. A water level observation port 17 is provided in the middle of the outer wall of the cleaning tank 1 away from the purified water tank 4. The inside of the water level observation port 17 is sealed with tempered glass. The top of the water level observation port 17 is lower than the height of the bottom end of the water filter slide 8. When the master batch is cleaned, the water level inside the cleaning tank 1 should be kept lower than the height of the top of the water level observation port 17 to avoid water leakage from the bottom end of the water filter slide 8 to the inside of the unloading slide 9 when the water level is too high, which affects the drying effect of the master batch.

[0027] The bottom of the inner wall of the cleaning tank 1 is provided with two limiting ring grooves 22 along its radial direction, and a transmission groove 18 is provided at the bottom of the cleaning tank 1. The transmission groove 18 is directly below one side of the bottom of the annular groove 11. The bottom of the interior of the cleaning tank 1 is provided with a stirring disk 10, and the stirring disk 10 is annular. The top of the stirring disk 10 is evenly installed with stirring bars 12 along its circumference. The length direction of the stirring bars 12 is the same as the radial direction of the stirring disk 10. The bottom of the stirring disk 10 is provided with an annular groove 11. An auger 2 is obliquely arranged at the center of the bottom of the inner wall of the cleaning tank 1, and an auger shaft 13 is installed inside the auger 2 along its axial rotation. A transmission box 14 is installed in the middle of the bottom of the cleaning tank 1, and an arc box 16 and a servo motor 15 are respectively installed on one side and the bottom of the outer wall of the transmission box 14. The output end of the servo motor 15 passes through the bottom of the transmission box 14 and extends to the inside thereof, and a transmission gear is installed at the output end of the servo motor 15.

[0029] In this embodiment, the centers of the annular groove 11 and the limiting annular groove 22 are coaxial with the axis of the cleaning tank 1, and the annular groove 11 is located between the two limiting annular grooves 22. Two convex rings are provided at the bottom of the stirring disk 10, and the bottoms of the convex rings are mounted inside the limiting annular grooves 22, so that the stirring disk 10 can rotate stably at the bottom of the cleaning tank 1 and drive the stirring bar 12 to rotate synchronously, thereby driving the water and masterbatch inside the cleaning tank 1 to rotate and stir in the same direction, and forming a vortex, transporting part of the water and masterbatch to the center of the bottom of the cleaning tank 1, which is convenient for the feeding and transportation of the auger 2.

[0030] In this embodiment, the bottom end of the auger shaft 13 passes through the bottom of the auger machine 2 and one side of the transmission box 14 in sequence and extends to the interior of the transmission box 14, and a bevel gear is installed at the bottom end of the auger shaft 13 to facilitate the bottom end of the auger shaft 13 to be set inside the transmission box 14 to facilitate power transmission.

[0031] In this embodiment, the interior of the arc box 16 is extended in the height direction and is connected to a flat bevel gear rod 19, the top of which passes through the bottom of the cleaning tank 1 and extends to the interior of the transmission groove 18. During the power transmission process, the power can be transmitted from the interior of the arc box 16 to the interior of the cleaning tank 1, so as to achieve the purpose of driving the stirring disk 10 to rotate, so that the masterbatch and water inside the cleaning tank 1 are stirred together, increasing the impact probability between the surface of the masterbatch and the water flow, improving the cleaning effect of the masterbatch, and avoiding the adhesion of dust and impurities on the surface of the masterbatch.

[0032] In this embodiment, one side of the inner wall of the annular groove 11 is a tooth surface, and the tooth surface of the annular groove 11 is meshed with the tooth surface at the top of the flat conical gear rod 19. The power is transmitted through the tooth surfaces of the flat conical gear rod 19 and the annular groove 11, thereby driving the agitator plate 10 to rotate at the bottom of the cleaning tank 1. By performing sealing treatment between the agitator plate 10 and the limiting annular groove 22 and between the flat conical gear rod 19 and the cleaning tank 1, water leakage in the cleaning tank 1 is avoided, which may affect the normal cleaning of the masterbatch.

[0033] In this embodiment, a double-headed gear rod 20 is rotatably connected to one side of the inner wall of the transmission box 14 close to the arc box 16, and a transition gear 21 is rotatably connected to one side of the inner wall of the transmission box 14. The transmission gear at the output end of the servo motor 15 is meshed with the bottom of the tooth surface of the transition gear 21, and then the power of the servo motor 15 is transmitted to different power transmission paths through the transition gear 21, so that the same power source can simultaneously drive the auger 2 and the stirring disk 10 to operate.

[0034] In this embodiment, the tooth surface of the transition gear 21 meshes with the tooth surface of the bevel gear and the tooth surface of one end of the double-headed gear rod 20 respectively, and the tooth surface of the other end of the double-headed gear rod 20 meshes with the tooth surface of the bottom end of the flat bevel gear rod 19. The transition gear 21 transmits the power generated by the servo motor 15 separately to the auger shaft 13 and the stirring disk 10, thereby synchronously driving the rotation of the auger shaft 13 and the stirring disk 10, so that the cleaning and conveying of the masterbatch inside the cleaning tank 1 are carried out synchronously, and cooperates with the continuous loading of the masterbatch conveying device outside the cleaning tank 1 to improve the cleaning efficiency of the masterbatch.
