Description

Technical Field

[0001] The utility model relates to the technical field of plastic particle cleaning, specifically to a cleaning device for plastic particle processing Background Art

[0002] Plastic particles are raw materials for plastic storage, transportation and processing in the form of semi-finished products. They are usually granular substances made from high molecular polymers through a series of processing processes such as polymerization, extrusion, and pelletizing. In the plastics industry, the quality and performance of plastic particles have a vital impact on the final quality of plastic products. During the production process, plastic particles are decomposed from plastics. They are of various types and often need to be cleaned. Therefore, plastic particle cleaning is an important part of the plastic recycling and reuse process. The purpose of cleaning is to remove dirt, impurities, oil, labels, glue and other attachments on the surface of plastic particles to improve the purity and quality of plastic particles so that they can meet the requirements of reprocessing and use.

[0003] Most of the plastic particle cleaning machines in the existing technology place plastic particles in water or cleaning liquid and stir and clean them through a stirring roller. Although this can meet the requirements of plastic particle cleaning, the cleaning effect on plastic particles is not high due to the relatively simple cleaning method. In addition, plastic particles are easily deposited on the bottom of the machine during continuous cleaning, resulting in some plastic particles being unable to be effectively cleaned, thereby affecting the cleaning effect of the plastic particles. Utility Model Content

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

The sieve plate 102 at the bottom of the top sieve box 101 is continuously hit by the cam 108 on the first rotating shaft 106 below to generate vibration, so that non-plastic particle garbage with larger impurities is screened, and the plastic particles are rubbed by the stirring mechanism 2 and the flushing mechanism 3 to achieve the cleaning effect.

[0029] like Figure 1 、 Figure 2 and Figure 5As shown, the inner wall of the screen box 101 is symmetrically provided with a slide groove 103, and a slider 104 is slidably connected to the inner wall of the slide groove 103. The two ends of the slider 104 are connected to the inner wall of the slide groove 103 by a spring 105. The outer wall of the slider 104 is fixedly connected to the screen plate 102. The inner wall of the shell 1 is located below the screen plate 102 and is rotatably connected to the first rotating shaft 106. The first rotating shaft 106 passes through the side wall of the shell 1 and is provided with a driven wheel 107. The middle part of the outer wall of the first rotating shaft 106 is fixedly connected to the cam 108. The screen plate 102 slides in the slide groove 103 through the sliders 104 on both sides, and the top and bottom are connected. The spring 105 is provided on the inside to further improve the shaking efficiency. The cam 108 is driven to move by the first rotating shaft 106. The stirring mechanism 2 includes a second rotating shaft 201 rotatably connected below the cam 108, and a stirring roller 202 is fixedly connected to the outer wall of the second rotating shaft 201. A brush 203 is provided on the outer wall of the stirring roller 202. One end of the second rotating shaft 201 passes through the side wall of the shell 1. The second rotating shaft 201 of the stirring mechanism 2 rotates to drive the stirring roller 202 on its outer wall to rotate together, so that the brush 203 on the outer wall of the stirring roller 202 continuously rubs and cleans with the plastic particles.

[0030] like Figure 3 and Figure 4 As shown, the flushing mechanism 3 includes a screen 301, which is fixedly connected to the inner wall of the shell 1 and is located below the stirring roller 202. The top of the screen 301 is slightly inclined, and the lower end is convenient for discharging. A punching plate 302 is provided below the screen 301. The inside of the punching plate 302 is hollow, and a nozzle 303 is fixedly connected to the upper top. A water inlet 304 is provided at the lower end of the punching plate 302. The setting of the screen 301 can better intercept plastic particles so that they will not fall onto the punching plate 302 below. The water flow from the lower water inlet 304 of the punching plate 302 is pressed into the plate and then sprayed out from the nozzle 303, thereby achieving the effect of flushing the plastic particles and continuously turning the plastic particles. Combined with the upper stirring roller 202 and the brush 203, the cleaning effect of the plastic particles can be greatly improved.

[0031] like Figure 3 and Figure 5As shown, the driving mechanism 4 includes a base plate 401, a driving motor 402 is provided on the top of the base plate 401, the output end of the driving motor 402 is sleeved with a driving wheel 403, the driving wheel 403 and the driven wheel 107 are sleeved with a synchronous belt 404, the output end of the driving motor 402 is fixedly connected to the second rotating shaft 201, and the driving motor 402 in the driving mechanism 4 works to drive the second rotating shaft 201 fixedly connected to its output end to rotate and drive the stirring roller 202 to work. When rotating, the driving wheel 403 and the synchronous belt 404 sleeved at the output end of the driving motor 402 will drive the driven wheel 107 to rotate, and further drive the first rotating shaft 106 to work. A discharge port 109 is provided on the outer wall of the shell 1, and the outer end of the discharge port 109 is rotatably connected to A first switch 110 and a drain outlet 111 are provided on the outer wall of the shell 1 below the discharge port 109, and a second switch 112 is provided at the end of the drain outlet 111. After the plastic particles are cleaned, the staff opens the first switch 110 to take out the plastic particles through the discharge port 109, and opens the second switch 112 to release the sewage through the drain outlet 111. The inside of the water inlet 304 is fixedly connected with a water inlet pipe 305, which runs through the side wall of the shell 1 and is provided with a booster pump 306 at the end. The booster pump 306 is fixedly connected to the outer wall of the shell 1. The staff can use the booster pump 306 to pump water into the water inlet pipe 305 with higher pressure, and press the water into the flushing plate 302 through the water inlet 304 for flushing.

[0032] Working principle: The staff turns on the boost pump 306 to connect to the water source and then starts the drive motor 402. The drive motor 402 uses the active wheel 403 sleeved on the output end and the synchronous belt 404 sleeved on it to drive the driven wheel 107 to work, and then drives the first rotating shaft 106 to rotate so that the cam 108 thereon continuously rotates and hits the upper screen plate 102 to move longitudinally, so as to achieve the effect of screening non-plastic particle garbage. Since the side wall of the screen plate 102 is connected to the slider 104, and the slider 104 is connected to the spring 105 inside the slide groove 103, the screen plate 102 is well limited so that it will not collide with the side wall of the shell 1. The driving motor 402 is further started, and its output end drives the second rotating shaft 201 and the stirring roller 202 thereon to rotate, thereby driving the brush 203 thereon and the plastic particles to be washed. Since the flushing plate 302 is hollow and a nozzle 303 is provided at the top, the booster pump 306 presses the water flow into the water inlet 304 at the bottom of the flushing plate 302 through the water inlet pipe 305, and further water flows out from the nozzle 303 of the flushing plate 302 to wash the plastic particles in multiple directions. After cleaning, the staff opens the discharge port 109 to take out the cleaned plastic particles, and opens the second switch 112 to discharge the sewage through the drain port 111.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
