Description

Technical Field

[0001] This invention relates to the technical field of plastic recycling, and in particular to a rinsing device for processing recycled PET bottle plastics. Background Technology

[0002] With the rapid development of the global plastics industry, the use of plastics is increasing, and plastic recycling has become extremely important. After plastic products are used, they can be recycled after being crushed, cleaned, and disinfected. In the process of plastic recycling, the cleaning of waste plastics is crucial because the degree of cleaning is closely related to the quality of recycled plastics.

[0003] A recycling production equipment for rinsing waste plastics, disclosed in Chinese patent application number CN202420497920.8, includes a rinsing mechanism. The rinsing mechanism includes a first push rod, one end of which is fixedly connected to one end of a moving rod, and the other side of the moving rod is fixedly connected to one end of a moving column. The teeth on the lower surface of the moving column mesh with the teeth of a swing plate. A groove at one end of the swing plate is slidably connected to the surface of a third circular rod. One end of the third circular rod is rotatably connected to one side of a turntable, and the middle of one side of the turntable is rotatably connected to one end of the first circular rod. During use, fine filamentous debris easily gets entangled on the rinsing rake, and there are gaps when the rinsing rake presses the plastic fragments into the water, making it difficult to thoroughly clean the plastic fragments.

[0004] A multifunctional circulating rinsing device for plastic recycling, Chinese patent application number CN202022132482.X, includes a rinsing tank, an air bladder, a filter screen, and branch pipes. A motor and a mounting plate are installed on the inner wall of the rinsing tank. A fixed bucket is fixedly mounted on one side of the mounting plate. A movable rod is located inside the fixed bucket. One end of the movable rod has a spring, and the other end has a pressure plate. A connecting pipe is connected to the air outlet of the air bladder. Multiple branch pipes are connected to the outside of the connecting pipe. Two pistons are located inside each branch pipe, with a sealing liquid between the two pistons. A connecting rod is connected to the bottom of the pistons, and a pressure block is connected to the other end of the connecting rod. A brush is fixedly mounted on one side of the pressure block. Multiple flip-tops are located in the middle of each branch pipe. The inner wall of each flip-top has barbs, and filter bags are fixed to the ends of the barbs. This device has the same problem as the device mentioned in the previous reference document.

[0005] In existing plastic rinsing equipment, the structure of the rinsing rake causes gaps when pressing plastic fragments into the water, reducing the efficiency of rinsing. If floating plastic fragments are discharged via overflow, the process is slow and prone to accumulation, further impacting rinsing efficiency. While adding an agitator at the overflow port helps discharge floating fragments, it also pushes water out, requiring continuous replenishment of water to the rinsing chamber, increasing costs.

[0018] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0019] Example 1 like Figures 1 to 5 As shown, a rinsing device for processing recycled PET bottles according to the present invention includes a rinsing chamber 1 and a screw feeder 2. The bottom of the rinsing chamber 1 is provided with an inclined surface, and a stirring assembly 3 is provided at the top of the rinsing chamber 1. A bottom discharge port 4 is provided at the bottom of the top of the screw feeder 2, and a top discharge port 5 is provided on the side of the rinsing chamber 1 near the screw feeder 2. A drive assembly 6 is also provided on the side of the rinsing chamber 1. During the rinsing of recycled PET bottles, the crushed plastic fragments are conveyed into the rinsing chamber 1 by a feeding device. With the assistance of the stirring assembly 3, the plastic fragments added to the rinsing chamber 1 are rinsed and processed. The drive assembly 6 is responsible for operating the stirring assembly 3. The system provides power. After rinsing, PET has a higher density than water, so the PET bottle fragments will gradually sink to the bottom of the rinsing chamber 1. The screw feeder 2 is used to assist in the discharge of plastic fragments from the lower layer of the rinsing chamber 1. With the assistance of the screw feeder 2, the PET bottle fragments are transported to the bottom discharge port 4 for discharge. The recycled PET bottles may contain bottles of other materials, which are prone to errors when sorted manually. Therefore, the plastic fragments added to the rinsing chamber 1 may also include plastic fragments of materials such as HDPE, which have a lower density than water. Therefore, they will float on the upper part of the liquid surface in the rinsing chamber 1 and be discharged from the top discharge port 5. The equipment can achieve the purpose of rinsing and classifying plastic fragments.

[0020] The stirring component 3 is used to allow the plastic fragments added to the rinsing chamber 1 to enter the water for rinsing and to assist in the discharge of the upper layer of plastic fragments in the rinsing chamber 1. When the stirring component 3 near the top discharge port 5 rotates, it will help push the plastic fragments floating on the liquid surface of the rinsing chamber 1 toward the top discharge port 5 so that they can be discharged smoothly.

[0021] The stirring assembly 3 includes a stirring rod 301, a stirring blade 302 on the stirring rod 301, and bearing seats 303 at both ends of the stirring rod 301. The bearing seats 303 are located at the upper end of the rinsing chamber 1. The stirring rod 301 is rotatably connected to the bearing seats 303. The stirring rod 301 is rotated with the assistance of the driving assembly 6. The rotation of the stirring rod 301 will cause the stirring blade 302 to rotate. When the stirring blade 302 rotates, it will press the plastic fragments floating on the water surface into the water, so that the plastic fragments are rinsed.

[0022] The stirring blade 302 is rectangular, and a groove 304 is provided on the side of the stirring blade 302 away from the stirring rod 301. After the plastic fragments are added into the rinsing chamber 1, some of the plastic fragments accumulate on the water surface due to the surface tension with the water. When the stirring blade 302 rotates, the groove 304 can quickly break up the plastic fragments and press them into the water, so that the plastic fragments can quickly come into contact with the water and carry out the rinsing process of the plastic fragments.

[0023] Drive assembly 6 includes a drive motor 601, which is located on the side of the rinsing chamber 1. A first drive gear is located at the output end of the drive motor 601. Two transmission gears 602 are located on the side of the stirring rod 301 near the drive motor 601. A drive chain 603 is connected between the first drive gear and the outer transmission gear 602. A first transmission chain 604 is connected between the corresponding transmission gears 602 on two adjacent stirring rods 301. A protective cover 605 is located on the outside of the first transmission chain 604 on the rinsing chamber 1. After startup, the output of the drive motor 601 drives the first drive gear to rotate. The first drive gear drives the transmission gear 602 to rotate through the drive chain 603. The rotation of the transmission gear 602 drives the stirring rod 301 to rotate. During the rotation of the stirring rod 301, through the assistance of another transmission gear 602 on the stirring rod 301, the corresponding transmission gear 602 on the adjacent stirring rod 301, and the first transmission chain 604, the adjacent stirring rods 301 also rotate synchronously, thereby causing all the stirring rods 301 to rotate.

[0024] The screw feeder 2 includes a discharge pipe 201 located at the lower end of the rinsing chamber 1. The upper end of the lower part of the discharge pipe 201 has an opening communicating with the rinsing chamber 1. A bottom discharge port 4 is located at the lower end of the upper part of the discharge pipe 201. A discharge motor 202 is installed at the upper end of the discharge pipe 201. A second drive gear 203 is installed at the output end of the discharge motor 202. A discharge screw 204 is rotatably installed inside the discharge pipe 201, rotating in conjunction with the discharge pipe 201. The shaft of the discharge screw 204 passes through the discharge pipe 201. A feed valve is located on one side of the shaft of the discharge screw 204 outside the discharge pipe 201. A second transmission chain 206 is provided between the driven gear 205, the second drive gear 203, and the driven gear 205. When the discharge motor 202 is started, the output end of the discharge motor 202 drives the second drive gear 203 to rotate. The rotation of the second drive gear 203 drives the rotation of the driven gear 205 through the second transmission chain 206. The rotation of the driven gear 205 drives the rotation of the discharge screw 204. During the rotation, the discharge screw 204 cooperates with the discharge pipe 201, so that the plastic fragments that have sunk to the bottom of the rinsing chamber 1 are gradually pushed upward along the discharge pipe 201, and then the plastic fragments are discharged through the bottom discharge port 4.

[0025] The lower end of the discharge pipe 201 is arc-shaped. A filter hole 207 is provided at the bottom of the lower end of the discharge pipe 201. A water collection hood 208 is provided at the lower end of the discharge pipe 201, located below the filter hole 207. A drain pipe 209 is provided on the side of the water collection hood 208. A circulation pump 210 is provided at the lower end of the rinsing chamber 1. The drain pipe 209 is connected to the circulation pump 210. The output end of the circulation pump 210 is connected to the upper end of the rinsing chamber 1. When the arc-shaped lower end of the discharge pipe 201 cooperates with the discharge screw 204, it allows the plastic fragments to... The movement is more stable, and it ensures that the plastic fragments that sink to the bottom of the rinsing chamber 1 are completely discharged. At the same time, when the discharge screw 204 rotates, it can also assist in clearing the plastic fragments that are blocked at the filter hole 207, ensuring the use of the filter hole 207. At the same time, the circulation pump 210 is started, so that the water in the water collection hood 208 re-enters the rinsing chamber 1 along the drain pipe 209, so that the water flow forms a circulation flow. When the water flow is in circulation, it is also conducive to the accumulation of plastic fragments at the filter hole 207, making the operation of the discharge screw 204 more efficient in discharging.

[0026] In the process of using this invention, the crushed plastic fragments are conveyed to the rinsing chamber 1 by the feeding device, and the drive motor 601 is started synchronously. The output end of the drive motor 601 drives the first drive gear to rotate. The first drive gear drives the transmission gear 602 to rotate through the drive chain 603. The rotation of the transmission gear 602 drives the stirring rod 301 to rotate. During the rotation of the stirring rod 301, through the assistance of another transmission gear 602 on the stirring rod 301, the corresponding transmission gear 602 on the adjacent stirring rod 301, and the first transmission chain 604, the adjacent stirring rods 301 also rotate synchronously, thereby causing all the stirring rods 301 to rotate. The rotation of the stirring rods 301 causes the stirring blades 302 to rotate.

[0027] After the plastic fragments are added into the rinsing chamber 1, some of the plastic fragments accumulate on the water surface due to the surface tension with the water. When the groove 304 on the stirring blade 302 rotates, it can quickly break up the plastic fragments and press them into the water, so that the plastic fragments can quickly come into contact with the water and carry out the rinsing process.

[0028] As the plastic fragments are rinsed, the discharge motor 202 is started simultaneously. The output end of the discharge motor 202 drives the second drive gear 203 to rotate. The rotation of the second drive gear 203 drives the driven gear 205 to rotate through the second transmission chain 206. The rotation of the driven gear 205 drives the discharge screw 204 to rotate. During the rotation, the discharge screw 204 cooperates with the discharge pipe 201, so that the plastic fragments that have sunk to the bottom of the rinsing chamber 1 are gradually pushed upward along the discharge pipe 201. Then the plastic fragments are discharged through the bottom discharge port 4.

[0029] At the same time, the circulation pump 210 is started, so that the water in the water collection hood 208 re-enters the rinsing chamber 1 along the drain pipe 209, so that the water flow forms a circulation flow. When the water flow is in circulation, it is also beneficial to make the plastic fragments gather at the filter hole 207, so that the discharge screw 204 can discharge more efficiently.

[0030] Example 2 Based on the rinsing equipment for PET bottle recycling plastic processing in Embodiment 1 above, during use, as plastic fragments on the water surface are broken up, the grooves 304 on the stirring blades 302 become defects, causing gaps in the stirring blades 302 when pressing the plastic fragments into the water. This reduces the efficiency of rinsing the plastic fragments. Simultaneously, the excessive agitation of the water surface caused by the rotation of the stirring blades 302 easily leads to water splashing, causing pollution to the surrounding environment and wasting water resources. Therefore, the following technical solution is proposed: like Figures 1 to 6As shown, the stirring blade 302 of the stirring assembly 3 located in the middle of the rinsing chamber 1 is rectangular, and the stirring blade 302 is provided with a plurality of first water passage holes 305. On the one hand, the first water passage holes 305 on the stirring blade 302 can reduce the splashing of water when the stirring blade 302 is stirring, and on the other hand, the overall rectangular structure of the stirring blade 302 can increase the area of ​​the stirring blade 302 pressing down the plastic fragments, so that the plastic fragments floating on the water surface are fully pressed into the water for rinsing, thereby improving the rinsing efficiency of the equipment for plastic fragments.

[0031] In the process of using this invention, the crushed plastic fragments are conveyed to the rinsing chamber 1 by the feeding device. The stirring blade 302 of the stirring assembly 3 near this position is rectangular, and a groove 304 is provided on the side of the stirring blade 302 away from the stirring rod 301. During the rinsing process, some plastic fragments accumulate on the water surface due to the surface tension with water. When the stirring blade 302 rotates, the groove 304 can quickly break up the plastic fragments and press them into the water, so that the plastic fragments can quickly come into contact with the water and carry out the rinsing process.

[0032] The stirring blade 302 of the stirring assembly 3 located in the middle of the rinsing chamber 1 is rectangular, and the stirring blade 302 is provided with multiple first water passage holes 305. On the one hand, the first water passage holes 305 on the stirring blade 302 can reduce the splashing of water when the stirring blade 302 is stirring, and on the other hand, the overall rectangular structure of the stirring blade 302 can increase the area of ​​the stirring blade 302 pressing down the plastic fragments, so that the plastic fragments floating on the water surface are fully pressed into the water for rinsing, thereby improving the rinsing efficiency of the equipment for plastic fragments.

[0033] Example 3 Based on the rinsing equipment for PET bottle recycling plastic processing in Embodiment 2 above, after the plastic fragments in the middle of the rinsing chamber 1 are rinsed, if the plastic fragments floating on the water surface are discharged through the top discharge port 5 by overflow, the efficiency is slow and it is easy for a large amount of plastic fragments to accumulate in the rinsing chamber 1, thereby affecting the efficiency of the rinsing process. After setting the stirring component 3 at the top discharge port 5, although the rotation of the stirring blade 302 can assist the discharge of the plastic fragments floating on the water surface, it will also push out water. As the rinsing process proceeds, water needs to be continuously replenished in the rinsing chamber 1, which increases the cost. Therefore, the following technical solution is proposed: like Figures 1 to 8As shown, the agitator blade 302 near the top discharge port 5 is rectangular and bent outward from the agitator rod 301. Multiple second water passage holes 306 are provided on the agitator blade 302. The agitator blade 302 is elastic. When the agitator blade 302 rotates, it engages with the inclined surface inside the rinsing chamber 1, pushing the plastic fragments floating on the water surface inside the rinsing chamber 1. Due to the bent and elastic design of the agitator blade 302, the plastic fragments between the agitator blade 302 and the inclined surface inside the rinsing chamber 1 are squeezed to reduce water residue in the plastic fragments. Then, as the agitator blade 302 rotates, when it is no longer in contact with the inclined surface inside the rinsing chamber 1, the elasticity of the agitator blade 302 pushes the squeezed-out plastic fragments towards the top discharge port 5, thus completing the discharge of the plastic fragments floating on the water surface inside the rinsing chamber 1. During this discharge process, water waste in the rinsing chamber 1 is reduced.

[0034] In the process of using this invention, the crushed plastic fragments are conveyed to the rinsing chamber 1 by the feeding device. The stirring blade 302 of the stirring assembly 3 near this position is rectangular, and a groove 304 is provided on the side of the stirring blade 302 away from the stirring rod 301. During the rinsing process, some plastic fragments accumulate on the water surface due to the surface tension with water. When the stirring blade 302 rotates, the groove 304 can quickly break up the plastic fragments and press them into the water, so that the plastic fragments can quickly come into contact with the water and carry out the rinsing process.

[0035] The stirring blade 302 of the stirring assembly 3 located in the middle of the rinsing chamber 1 is rectangular, and the stirring blade 302 is provided with multiple first water passage holes 305. On the one hand, the first water passage holes 305 on the stirring blade 302 can reduce the splashing of water when the stirring blade 302 is stirring, and on the other hand, the overall rectangular structure of the stirring blade 302 can increase the area of ​​the stirring blade 302 pressing down the plastic fragments, so that the plastic fragments floating on the water surface are fully pressed into the water for rinsing, thereby improving the rinsing efficiency of the equipment for plastic fragments.

[0036] When plastic fragments floating on the water surface in the rinsing chamber 1 are discharged, the stirring blades 302 of the stirring assembly 3 near the top discharge port 5 rotate and cooperate with the inclined surface inside the rinsing chamber 1. This pushes the plastic fragments floating on the water surface in the rinsing chamber 1. Because the stirring blades 302 are curved and elastic, the plastic fragments between the stirring blades 302 and the inclined surface inside the rinsing chamber 1 are squeezed to reduce the amount of water remaining in the plastic fragments. Then, as the stirring blades 302 rotate, when the stirring blades 302 are no longer in contact with the inclined surface inside the rinsing chamber 1, the elasticity of the stirring blades 302 pushes the plastic fragments after the water is squeezed out towards the top discharge port 5, thereby completing the discharge of the plastic fragments floating on the water surface in the rinsing chamber 1. During the discharge process, water waste in the rinsing chamber 1 is reduced.

[0037] The main function achieved by this invention is as follows: by setting different shapes of the stirring blades 302 in the stirring assembly 3, the stirring blades 302 near the feeding area of ​​the feeding device can quickly break up the plastic fragments and press them into the water when rotating, so that the plastic fragments can quickly come into contact with the water for rinsing. The first water passage hole 305 on the stirring blades 302 in the middle of the rinsing chamber 1 can reduce the splashing of water when the stirring blades 302 are stirring. The overall rectangular structure of the stirring blades 302 can increase the area on which the stirring blades 302 press down the plastic fragments, so that the plastic fragments floating on the water surface can be fully pressed into the water for rinsing. The stirring blades 302 near the top discharge port 5 cooperate with the inclined surface inside the rinsing chamber 1 to squeeze out the water in the plastic fragments and push them towards the top discharge port 5 to assist in discharge, thereby reducing the waste of water in the rinsing chamber 1.

[0038] The rinsing equipment for recycling PET bottles of the present invention can be installed, connected, or set up in a manner that is common in mechanical systems. Any method that can achieve its beneficial effects can be implemented.
