Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figures 1 to 6 As shown, a polymer plastic masterbatch circulation cleaning device comprises a cleaning tank 1, a support frame 2, a first cleaning mechanism 3, a second cleaning mechanism 4 and a solid-liquid separation mechanism 5, wherein the cleaning tank 1 is fixedly arranged on the support frame 2, and a feed port 11, a water injection port 12 and a discharge port 13 are arranged on one side of the cleaning tank 1, wherein the feed port 11 and the water injection port 12 are located at the top of the cleaning tank 1, and the discharge port 13 is located at the bottom of the cleaning tank 1, the plastic particles to be cleaned are added into the cleaning tank 1 through the feed port 11, and an appropriate amount of water is added through the water injection port 12.

[0027] The first cleaning mechanism 3 includes a cleaning cylinder 31, a first blade 32 and a first driving assembly 33. The cleaning cylinder 31 is rotatably arranged in the cleaning tank 1. Both ends of the cleaning cylinder 31 are open. The feed port 11, the water injection port 12 and the discharge port 13 are all connected to the cleaning cylinder 31. Plastic particles and water enter the cleaning cylinder 31 through the feed port 11 and the water injection port 12, respectively, and form a mixture in the cleaning cylinder 31. The first blade 32 is fixedly arranged on the inner wall of the cleaning cylinder 31. The first driving assembly 33 is used to drive the cleaning cylinder 31 to rotate in the cleaning tank 1. By starting the first driving assembly 33, the cleaning cylinder 31 is driven to rotate in the cleaning tank 1, so that the first blade 32 moves with the rotation of the cleaning cylinder 31, and the mixture formed by the plastic particles and water is preliminarily stirred, thereby cleaning the plastic particles.

[0028] The second cleaning mechanism 4 includes a rotating shaft 41, a second blade 42 and a second driving assembly 43. The rotating shaft 41 is rotatably disposed in the cleaning tank 1 and penetrates the cleaning cylinder 31. The second blade 42 is fixedly arranged on the rotating shaft 41. The second driving assembly 43 is started to drive the rotating shaft 41 to rotate in the cleaning tank 1. The second blade 42 moves with the rotation of the rotating shaft 41 to further stir and clean the plastic particles.

[0029] The first blade 32 and the second blade 42 rotate in the cleaning tank 1, thereby promoting the mixture formed by the plastic particles and water in the cleaning tank 1 to flow. In addition, when the first blade 32 and the second blade 42 rotate in different directions, a complex flow pattern can be generated in the cleaning tank 1, which not only increases the flow speed and range of the mixture, but also causes the mixture to form eddies and turbulence in multiple directions in the tank. These eddies and turbulences can penetrate into every corner and crevice of the cleaning tank 1, thereby ensuring that the plastic particles in every corner of the cleaning tank 1 can be fully cleaned.

[0030] The solid-liquid separation mechanism 5 includes a separation box 51 and a filter plate 52. The separation box 51 is connected to the discharge port 13. The filter plate 52 is fixedly installed in the separation box 51. A drain port 53 is provided at the bottom of the separation box 51, and the filter plate 52 is located between the discharge port 13 and the drain port 53. After cleaning, the discharge port 13 is opened to discharge the mixture of plastic particles and water into the separation box 51. Under the action of gravity and the filter plate 52, water passes through the filter plate 52 and is discharged from the drain port 53, while the cleaned plastic particles remain on the top of the filter plate 52, thereby achieving effective separation of plastic particles and water.

[0031] refer to Figure 1 and Figure 3 As shown, in some specific embodiments, in order to further improve the effect and cleanliness of solid-liquid separation, the solid-liquid separation mechanism 5 also includes a flushing component 54, the flushing component 54 includes a spray rack 55 and a nozzle 56, the spray rack 55 is fixedly arranged on the top of the separation box 51, and a plurality of nozzles 56 are provided, and all nozzles 56 are arranged in a matrix and fixed on the spray rack 55. When the plastic particles are discharged from the discharge port 13, the nozzles 56 on the spray rack 55 will sequentially spray high-pressure water flow to flush the plastic particles. The flushed water flow is discharged through the drain port 53, and the cleaned plastic particles remain in the separation box 51. The flushing component 54 can improve the cleaning effect of the cleaning device.

[0032] refer to Figure 1 and Figure 3As shown, in some specific embodiments, in order to ensure that the water is discharged smoothly, the solid-liquid separation mechanism 5 further includes a guide plate 57, which is fixedly installed in the separation box 51, one end of the guide plate 57 is connected to the filter plate 52, and the other end of the guide plate 57 is located at the drain port 53. When the mixture of plastic particles and water enters the separation box 51, it is first separated into solid and liquid by the filter plate 52. The plastic particles are intercepted by the filter plate 52 and remain on the top, while the water flows into the guide plate 57 below through the pores of the filter plate 52. Since one end of the guide plate 57 is connected to the filter plate 52 and the other end is located at the drain port 53, the water can flow smoothly to the drain port 53 along the guide plate 57 and be discharged.

[0033] refer to Figure 5 As shown, in some specific embodiments, in order to realize the rotation of the cleaning cylinder 31 in the cleaning tank 1, the first driving assembly 33 includes a transmission shaft 34 and a first motor 35, the transmission shaft 34 is rotatably arranged on the support frame 2, a first gear 36 is fixedly arranged on the outer side of the cleaning cylinder 31, a second gear 37 matching the first gear 36 is fixedly arranged on the transmission shaft 34, the first motor 35 is fixedly arranged on the support frame 2, and the output end of the first motor 35 is coaxially fixedly connected with the transmission shaft 34. When the cleaning cylinder 31 is required to rotate in the cleaning tank 1, the first motor 35 is started. The output end of the first motor 35 starts to rotate, driving the transmission shaft 34 coaxially connected thereto to rotate together. The second gear 37 on the transmission shaft 34 rotates and meshes with the first gear 36, thereby driving the cleaning cylinder 31 to rotate synchronously. By adjusting the rotation speed and rotation direction of the first motor 35, the rotation speed and direction of the cleaning cylinder 31 can be controlled to meet different cleaning requirements.

[0034] refer to Figure 6 As shown, in some specific embodiments, in order to realize the rotation of the rotating shaft 41 in the cleaning tank 1, the second driving assembly 43 includes a second motor 44, the second motor 44 is fixedly arranged on the support frame 2, and the output end of the second motor 44 is coaxially fixedly connected with the rotating shaft 41. When the rotating shaft 41 is required to rotate in the cleaning tank 1, the second motor 44 is started. The output end of the second motor 44 starts to rotate, driving the rotating shaft 41 coaxially connected thereto to rotate together. By adjusting the speed and rotation direction of the second motor 44, the rotation speed and direction of the rotating shaft 41 can be controlled to meet different cleaning requirements.

[0035] In order to facilitate the understanding of the embodiments of the present invention by those skilled in the art, the working principle of the embodiments of the present invention is now described in combination with specific application scenarios:

[0036] In actual use, the plastic particles to be cleaned are added into the cleaning tank 1 through the feed port 11. A proper amount of water is added into the cleaning tank 1 through the water injection port 12 to mix the plastic particles with the water.

[0037] The first motor 35 in the first driving assembly 33 is started. The output end of the first motor 35 drives the transmission shaft 34 to rotate, and the second gear 37 on the transmission shaft 34 meshes with the first gear 36 outside the cleaning cylinder 31, thereby driving the cleaning cylinder 31 to rotate in the cleaning tank 1. The first blade 32 in the cleaning cylinder 31 moves with the rotation of the cleaning cylinder 31, and preliminarily stirs and cleans the mixture formed by the plastic particles and water.

[0038] At the same time, the second motor 44 in the second driving assembly 43 is started. The output end of the second motor 44 is coaxially fixedly connected to the rotating shaft 41, driving the rotating shaft 41 to rotate in the cleaning tank 1. The second blade 42 on the rotating shaft 41 moves with the rotation of the rotating shaft 41 to further stir and clean the plastic particles. The rotation of the first blade 32 and the second blade 42 forms a complex flow pattern in the cleaning tank 1, which helps to reduce cleaning dead corners and improve the uniformity and efficiency of cleaning.

[0039] After cleaning is completed, the discharge port 13 is opened, and the mixture of plastic particles and water enters the separation box 51 in the solid-liquid separation mechanism 5. Under the action of gravity and the filter plate 52, water passes through the filter plate 52 and is discharged from the drain port 53, while the cleaned plastic particles remain on the top of the filter plate 52. The nozzle 56 on the spray rack 55 sprays high-pressure water to rinse the plastic particles, further improving the cleaning effect. The rinsed water is also discharged through the drain port 53. The guide plate 57 ensures that the water can flow smoothly to the drain port 53 and be discharged to avoid water accumulation.

[0040] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
