Description

Technical Field

[0002] Environmentally friendly PVC particles are plastic particles made by blending and modifying PVC resin powder with environmentally friendly heat stabilizers, plasticizers, lubricants, processing aids and other additives. Due to the use of environmentally friendly additives, environmentally friendly PVC particles will not produce irritating odor during use. And good fluidity helps to maintain the uniformity and stability of the material during processing.

When the existing cleaning device cleans PVC particles, the plastic particles are directly placed in the water pool for cleaning. The cleaning effect is relatively poor and the impurities on the surface of the PVC particles cannot be completely cleaned. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0023] See also Figure 1 , 2 , 3, and 4, the utility model provides a technical solution: an environmentally friendly PVC particle cleaning device, comprising: a recycling pool 1, the recycling pool 1 is a cavity with an opening on the top, and a water pump 14 for water circulation is fixedly connected to the side of the recycling pool 1; a cleaning bucket 2 is fixedly connected to the top of the recycling pool 1, and a pipeline connected to the recycling pool 1 is provided at the bottom of the cleaning bucket 2, and a solenoid valve is provided on the outside of the pipeline, an inlet and outlet is provided at the top of the recycling pool 1, and a water permeable hole 3 is provided in the middle of the recycling pool 1; a cleaning part is placed in the cleaning bucket 2, and the cleaning part includes an upper A conical barrel 6 is slidingly arranged inside the cleaning barrel 2, and a vertical drainage hole is arranged on the outer side of the conical barrel 6. A circular brush 12 for cleaning is rotatably arranged on the outer side of the conical barrel 6; a driving part is placed inside the conical barrel 6, and the driving part includes a lead screw 13 fixed to the inside of the cleaning barrel 2, and a worm gear 10 is threadedly connected to the outer side of the lead screw 13. The outer side of the worm gear 10 is transmission-connected to the circular brush 12 through a connecting sleeve 11. When the worm gear 10 rotates, the conical barrel 6 is driven to rise and fall and the circular brush 12 is driven to rotate on the outer side of the conical barrel 6.

[0024] It should be noted that in the present utility model, the PVC particles to be cleaned are quantitatively placed into the cleaning barrel 2 from the top of the cleaning barrel 2 through a screw conveyor. The conical barrel 6 is located at the bottom of the cleaning barrel 2. The water pump 14 injects water into the interior of the cleaning barrel 2. The water is mixed with the PVC particles. As the water is continuously injected, the water is discharged from the water permeable holes 3, thereby discharging the floating matters. After standing for a period of time, the driving part drives the worm gear 10 to rotate. Its principle is similar to that of a screw jack. Under the reaction force of the force, the conical barrel 6 slowly moves upward along the lead screw 13. At the same time, the worm gear 10 drives the circular brush 12 to rotate on the outer side of the conical barrel 6 through the connecting sleeve 11, so that the circular brush 12 comes into contact with and rubs against the PVC particles, thereby cooperating with the clean water inside to clean them. When the bottom of the conical barrel 6 is higher than the water permeable holes 3, the PVC particles are separated from the water, and thus are drained during the upward movement. When the bottom of the conical barrel 6 is connected to the top of the cleaning barrel 2, the PVC particles flow into the guide plate 5 along the inclined surface of the conical barrel 6 and are collected for the next operation.

[0025] Please refer to Figure 1 、 3 As shown in FIGS.

[0026] It should be noted that the input end of the water pump 14 of the present utility model is located between the filter screen 15 and the inner wall of the recovery tank 1. The water is discharged into the recovery tank 1 through the water permeable holes 3 or the solenoid valve at the bottom of the cleaning barrel 2, and then enters the side of the input end of the water pump 14 through the filtration of the filter screen 15. The water pump 14 can discharge the filtered water into the cleaning barrel 2. When the conical barrel 6 moves upward, the water and hot air pass through the water permeable holes 3 and are discharged downward with the conical barrel 6. The air duct 4 is connected to the external fan through a pipeline. During the upward movement of the conical barrel 6 with the PVC particles, the circular brush 12 stirs the PVC particles, and the air duct 4 blows air on them to reduce the humidity on their outer sides.

[0027] Please refer to Figure 2 、 3 As shown in FIGS.

[0028] It should be noted that, under the cooperation of the limiting groove 17 and the limiting block of the present utility model, the conical barrel 6 moves vertically up and down along the cleaning barrel 2, preventing the conical barrel 6 from rotating or shifting. When the worm gear 10 and the lead screw 13 move along the length direction of the lead screw 13 under the action of limiting, the worm gear 10 drives the circular brush 12 to rotate through the connecting sleeve 11. The circular brush 12 cleans and stirs on the outer side of the conical barrel 6. However, when the conical barrel 6 is separated from water, the circular brush 12 can reciprocally stir the PVC particles to make them contact with the wind. When the conical barrel 6 is located at the top of the cleaning barrel 2, the circular brush 12 can prevent the PVC particles from adhering to or adsorbing on the surface of the conical barrel 6, facilitating the cleaning of the surface of the conical barrel 6.

[0029] Please refer to Figure 3 、 4 As shown, the conical barrel 6 is slidably disposed outside the lead screw 13. A transmission box 7 is slidably connected to the outside of the lead screw 13. The conical barrel 6 is fixedly connected to the transmission box 7. A first motor 8 is fixedly connected to one side of the transmission box 7. The output end of the first motor 8 is fixedly connected with a worm 9. The worm 9 meshes with the worm gear 10. The connecting sleeve 11 is rotatably connected inside the transmission box 7. The bottom of the connecting sleeve 11 is fixedly connected with the worm gear 10.

[0030] It should be noted that the worm gear 10 of the present utility model is rotatably installed inside the transmission box 7. The first motor 8 drives the worm 9 to rotate through the worm 9. The worm 9 drives the worm gear 10 to rotate. The worm gear 10 is threadedly connected with the lead screw 13. Since the transmission box 7 is fixedly connected with the conical barrel 6, the conical barrel 6 can only move in the vertical direction under the cooperation of the limiting block and the limiting groove 17. In this way, the worm gear 10 drives the transmission box 7 and the conical barrel 6 to move up and down. And while the worm gear 10 rotates, it drives the circular brush 12 to move through the connecting sleeve 11, and the stirring and cleaning of the PVC particles are realized through the circular brush 12.
