Description

Technical Field

[0001] The present invention relates to the technical field of plastic recycling, and in particular to a particle cleaning device for plastic recycling. Background Art

[0002] The cleaning process for plastic recycling typically includes pretreatment, crushing, cleaning, dehydration, and drying. Cleaning equipment is primarily used during the cleaning phase. Common cleaning equipment includes friction cleaners, vortex cleaners, ultrasonic cleaners, and rinsing tanks. Each device has different operating principles and application scenarios. For example, friction cleaners are suitable for removing surface deposits, while vortex cleaners use eddy currents to separate impurities.

[0003] Document CN118876282B states that existing friction cleaning machines are susceptible to interference from wastewater after friction cleaning plastic particles, resulting in poor cleaning performance. Furthermore, when the friction chamber becomes clogged, while the chamber expands, this part of the material is easily discharged directly, rendering it ineffective cleaning. By providing a variable friction chamber, the amount of material on both sides of the friction chamber becomes uniform, avoiding localized blockages and ensuring uniform material distribution and consistent cleaning.

[0004] However, in practice, it has been found that when cleaning crushed particles, existing cleaning devices often have problems because the particles are often of different sizes and a large number of particles are cleaned at once. This leads to insufficient cleaning of the particles and poor cleaning effect. The existing solution is to extend the cleaning time or repeat the cleaning process multiple times to improve the cleaning effect. However, this method indirectly increases water consumption and leads to low water resource utilization, resulting in water waste. Summary of the Invention

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0017] Example 1

[0018] Refer to the attached Figure 1-6 , a particle cleaning device for plastic recycling, comprising a dry cleaning device mounted within a housing 100; The dry cleaning device is composed of a number of equally spaced adsorption mechanisms 1 and conveying cylinders 2, with a rotatable conveying cylinder 2 provided between adjacent adsorption mechanisms 1; The adsorption mechanism 1 includes a mounting circular seat 11, in which a plurality of equally spaced adsorption seats 12 are rotatably mounted. One end of an adsorption tube 13 is fixedly connected to the adsorption seat 12. The other end of the adsorption tube 13 is rotatably mounted in an adsorption circular box 14. The adsorption circular box 14 is externally connected to a suction fan 600. The adsorption round box 14 is fixedly mounted with a friction ball 400, the conveying cylinder 2 is mounted with a driving ring 3 and a cleaning ring 4, the driving ring 3 is fixedly mounted with an elastic friction pad 500 in contact with the friction ball 400, and the cleaning ring 4 is mounted with a brush 5 with one end located in the mounting round seat 11; Both sides of the adsorption seat 12 are provided with dust discharge grooves 16 that penetrate the mounting round seat 11. The dust discharge grooves 16 are fixed and connected to the dust discharge circular box 15. The dust discharge circular box 15 is connected to the dust discharge pipe 17. The dust discharge pipe 17 is externally connected to the first vacuum cleaner 700.

[0019] When using existing cleaning devices for cleaning, since the particles are often of different sizes and a large number of particles are cleaned at one time, a large number of particles will accumulate, and the accumulated particles will form cleaning dead corners, resulting in insufficient particle cleaning. In order to solve this problem, the cleaning time needs to be extended, which in turn causes the problem of water waste.

[0020] The present invention forms a dry cleaning device through several adsorption mechanisms 1 and conveying cylinders 2. The core idea is to first dry clean the particles to remove the easy-to-clean dust from the particles through dry cleaning, so that in the subsequent water washing stage, the cleaning time is greatly shortened to reduce water resource usage.

[0021] Specifically, when in use, particles are input into the rotating conveying drum 2. As the conveying drum 2 rotates, the particles advance in the conveying drum 2 and rotate, and then enter the adsorption mechanism 1. At this time, the suction fan 600 is started, and the adsorption seat 12 generates suction through the adsorption box 14. The particles entering the adsorption mechanism 1 are adsorbed by the adsorption seat 12, and each adsorption seat 12 only adsorbs a single particle. Therefore, accumulation will not occur at the adsorption mechanism 1, avoiding the existence of cleaning dead corners. Subsequently, while the conveying cylinder 2 is rotating, the conveying cylinder 2 drives the driving ring 3 and the cleaning ring 4 to rotate. The driving ring 3 drives the friction ball 400 to rotate through the elastic friction pad 500, thereby causing the friction ball 400 to drive the adsorption tube 13 to rotate, and the adsorption tube 13 in turn drives the adsorption seat 12 to rotate. Therefore, the particles adsorbed by the adsorption seat 12 will rotate. At the same time, the cleaning ring 4 drives the bristles 5 to rotate, so that the particles can be cleaned in all directions, thereby achieving a dry cleaning effect. The dust brushed off will enter the dust discharge chute 16. At this time, the first vacuum cleaner 700 is started, and the dust can be sucked away and discharged through the dust discharge box 15, thereby avoiding re-contamination of particles.

[0022] It should also be noted that, in this embodiment, the rotation direction of the elastic friction pad 500 is consistent with that of the conveying cylinder 2, while the rotation direction of each adsorption seat 12 is different, but they can all drive the particles adsorbed by them to rotate, and in this embodiment, the elastic friction pad 500 is made of sponge material, and can also be made of rubber material.

[0023] Therefore, the present invention, through this setting, can perform waterless dry cleaning on the particles, and can clean the particles one by one, so that no dead corners are produced during cleaning, the cleaning effect is improved, and the time for subsequent water washing can be shortened, reducing the utilization of water resources.

[0024] Specifically, such as Figure 6As shown, the ash discharge box 15 is fixed on the mounting round seat 11, the filter ring 18 is fixedly installed in the ash discharge trough 16, the adsorption tube 13 passes through the mounting round seat 11 and is connected to the adsorption seat 12, and a rubber sleeve 19 is installed at the port of the adsorption seat 12.

[0025] During operation, a large amount of particles will enter the mounting round seat 11 as it moves. By installing the filter ring 18, the particles can be prevented from accidentally entering the ash discharge chute 16. Moreover, due to the different sizes of the particles, some particles that are too small may enter the adsorption seat 12, causing the adsorption seat 12 to be blocked. This situation is prevented by providing the rubber sleeve 19. When in use, the rubber sleeve 19 will open due to suction. After the suction ends, the rubber sleeve 19 will return to its original shape due to its own elastic force, and the adsorption seat 12 can be closed.

[0026] In addition, the adsorption circular box 14 is fixedly connected to the shell 100, the dust discharge pipe 17 passes through the shell 100 and is fixedly connected thereto, the diameters of the conveying cylinder 2 and the mounting round seat 11 are consistent, and the two are seamlessly connected, the suction fan 600 and the first dust collector 700 are both fixedly installed outside the shell 100, and in this embodiment, in order to ensure the dry cleaning effect, a suction fan 600 and a first dust collector 700 are set at each mounting round seat 11.

[0027] like Figure 1 and 2 As shown, the conveying cylinders 2 at both ends of the dry cleaning device are respectively connected to the feeding cylinder 7 and the output cylinder 300. The output cylinder 300 is rotatably connected to the conveying cylinder 2 at one end, and the output cylinder 300 is fixed on the shell 100. The conveying cylinder 2 at the other end is fixedly installed with a gear sleeve 8. The feeding cylinder 7 and the gear sleeve 8 are rotatably connected. A feed hopper 200 connected to the feeding cylinder 7 is fixedly installed outside the shell 100.

[0028] During the specific operation, the particles are transported into the feed tube 7 through the feed hopper 200, and then transported into the conveying tube 2 through the feed tube 7. After the dry cleaning is completed, the particles are discharged through the output tube 300. During the operation, the feed tube 7 and the output tube 300 do not rotate.

[0029] Example 2

[0030] Reference Figure 1-Figure 3 Based on the first embodiment, a motor 9 is fixedly mounted on the shell 100, and a gear 10 located in the shell 100 is mounted on the output end of the motor 9. The gear 10 is meshed with the gear sleeve 8. A connecting rod 6 is fixedly mounted between the conveying cylinders 2. The conveying cylinder 2 is provided with a plurality of equidistantly distributed filtering holes. A screw conveyor 800 extending into the plurality of conveying cylinders 2 is provided in the driving ring 3. The screw conveyor 800 is mounted on the shell 100. Several second vacuum cleaners 1000 are installed below the shell 100. The second vacuum cleaners 1000 are connected to the dust discharge cabinet 900.

[0031] In this embodiment, in order to ensure the effect of particles moving in the conveying cylinder 2, a screw conveyor 800 is provided, so that the particles can be ensured to move in the conveying cylinder 2 through the screw conveyor 800, and in order to improve the effect of dry cleaning and dust removal, the conveying cylinder 2 is set to have a filter hole shape.

[0032] During specific operation, the particles are fed into the feed cylinder 7 through the feed hopper 200, and the screw conveyor 800 is started to move the particles in the plurality of conveying cylinders 2. At this time, the motor 9 is started, and the gear 10 can engage the gear sleeve 8 to rotate. Since the plurality of gear sleeves 8 are fixedly connected by the connecting rod 6, all the conveying cylinders 2 can be driven to rotate, thereby achieving the effects mentioned in the above embodiment. In this embodiment, it is important to explain the following: during the rotation of the conveying cylinder 2, due to the provision of filtering holes, a portion of the dust carried by the particles can be shaken off, and the dust will fall to the bottom of the shell 100. By starting the second vacuum cleaner 1000, the dust can be sucked into the dust discharge cabinet 900.

[0033] In other embodiments, the dry cleaning device of the present invention has both dry cleaning and water washing functions, which are briefly described here. Based on the above-mentioned embodiments one and two, after dry cleaning is completed, water is introduced into the housing 100, and the adsorption mechanism 1 operates normally, so that the adsorption seat 12 continues to adsorb particles, the conveying cylinder 2 rotates normally, and the water source is set to the spray mode of existing cleaning devices, thereby achieving a water washing effect.
