Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0032] Please refer to Figure 1 - Figure 5As shown, the present application is a kind of multilayer colored plastic particle production cleaning system, including lower cleaning tank 1 and the upper cleaning tank 2 arranged above lower cleaning tank 1, one end of lower cleaning tank 1 is provided with air-drying conveying cylinder 3, and the side of air-drying conveying cylinder 3 is connected with one end of lower cleaning tank 1 through connecting channel 12, the other end of air-drying conveying cylinder 3 is arranged above upper cleaning tank 2 and the end part below is provided with upper discharge port 30, the upper part of lower cleaning tank 1 is connected with the lower part of upper cleaning tank 2 through connecting pipe 101, the inside of lower cleaning tank 1 is provided with lower conveying line 11, the inside of upper cleaning tank 2 is provided with upper conveying line 21, in addition, the inside of lower cleaning tank 1 and the side of connecting channel 12 are provided with falling slide plate 10, colored plastic particle cleaning fluid flows down from the upper part of upper cleaning tank 2, then enters lower cleaning tank 1, at the same time, colored plastic particle is conveyed by lower conveying line 11 in lower cleaning tank 1, then moves upward in air-drying conveying cylinder 3 under the action of air-drying conveying cylinder 3, enters upper conveying line 21 in upper cleaning tank 2, further clean cleaning is carried out by cooperating with more clean colored plastic particle cleaning fluid, effectively solve the problem of increasing work intensity caused by sequentially placing colored plastic particle in multiple cleaning tanks for cleaning in the cleaning process of colored plastic particle.

[0033] In the cleaning process, the continuity of colored plastic particle cleaning is ensured, at the same time, cleaning fluid flows from top to bottom, colored plastic particle moves from bottom to top, forms interaction, ensures full use of cleaning fluid, on the other hand, ensures the continuity of cleaning, saves the use of cleaning fluid and the qualified rate of colored plastic particle surface cleaning.

[0034] Among them, the upper surface of upper conveying line 21 is in inclined state, and the end close to air-drying conveying cylinder 3 is lower than the end away from air-drying conveying cylinder 3, similarly, the upper surface of lower conveying line 11 is also in inclined state, but the end close to air-drying conveying cylinder 3 is higher than the end away from air-drying conveying cylinder 3.

[0035] Specifically, referring to Figure 2 and Figure 3 As shown, the side away from connecting channel 12 below air-drying conveying cylinder 3 is provided with main air blower 31, the side above air-drying conveying cylinder 3 is provided with turning air cylinder 320 and the end part is provided with turning air blower 32, the center line of upper discharge port 30 is vertically downward.

[0036] In addition, the end part above air-drying conveying cylinder 3 is designed as accelerating arc top 300, the side away from accelerating arc top 300 of upper discharge port 30 is provided with anti-backflow stop 301.

[0037] Second, the connecting channel 12 is rotatably provided with a rotating blade 121 near one end of the air-drying conveying cylinder 3, the rotating blade 121 is designed without power and kept rotating under the action of the main fan 31, so that the colored plastic particles can be effectively scattered and pushed into the air-drying conveying cylinder 3. After the colored plastic particles in the lower cleaning tank 1 are cleaned and enter the air-drying conveying cylinder 3 through the connecting channel 12, the main fan 31 blows the colored plastic particles upward, and the rotating fan 32 blows the colored plastic particles to the position of the accelerating arc-shaped top 300 on one side of the upper discharge port 30, and then the colored plastic particles are accelerated to flow downward from the upper discharge port 30 under the action of the anti-backflow stopper 301, and then quickly fall into the cleaning liquid on the upper conveying line 21, and then flow upward under the action of the upper conveying line 21, and then fall from the finished product port 201. After being cleaned once, the colored plastic particles are dried and then cleaned again to better remove unstable colors on the surface.

[0038] Referring to Figure 4 As shown in the drawings, a plurality of rotating shafts 1110 are rotatably arranged on the lower conveying line 11 at equal intervals, and a movable feeding plate 111 is arranged above the rotating shafts 1110;

At the same time, the colored plastic particles float on the surface of the cleaning liquid and move upward under the action of the movable feeding plate 111. When the colored plastic particles move with the movable feeding plate 111 to one end of the lower cleaning tank 1 near the air-drying conveying cylinder 3, the colored plastic particles can slide onto the connecting channel 12 under the action of the discharging slide plate 10, and then be conveyed to the upper part for secondary cleaning under the action of the air-drying conveying cylinder 3. By designing the movable feeding plate 111 to be rotatable and resettable, it is ensured that the movable feeding plate 111 can be quickly reset after the colored plastic particles fall onto the discharging slide plate 10, so that the colored plastic particles will not be spilled during the conveying process.

[0042] In addition, a plurality of fixed feeding plates 211 are arranged at equal intervals above the upper conveying line 21. Since the fixed feeding plates 211 can convey the colored plastic particles to the finished product outlet 201, the fixed feeding plates 211 can be designed as fixed type. It should be noted that if the structure similar to the feeding slide plate 10 in the lower cleaning tank 1 is designed in the upper cleaning tank 2, the structure of the fixed feeding plate 211 can also be designed as the structure of the movable feeding plate 111.

[0043] Finally, the water outlet 102 is arranged at the end of the lower cleaning tank 1 away from the air-drying conveying cylinder 3. The feeding inlet 103 is arranged above the end of the lower cleaning tank 1 away from the air-drying conveying cylinder 3. The water inlet 20 is arranged above the end of the upper cleaning tank 2 away from the air-drying conveying cylinder 3. The finished product outlet 201 is arranged at the end of the upper cleaning tank 2 away from the air-drying conveying cylinder 3.

[0045] Step 1: Connect the water inlet 20 with the colored plastic particle cleaning liquid conveying pipeline, and connect the feeding inlet 103 with the colored plastic particle conveying device.

[0046] Step 2: Start the production cleaning system. The cleaning liquid flows into the upper conveying line 21 in the upper cleaning tank 2 through the water inlet 20, and then flows into the lower conveying line 11 in the lower cleaning tank 1 through the connecting pipe 101.

[0047] At the same time, the colored plastic particles fall from the feeding inlet 103, are conveyed upwards by the movable feeding plate 111 on the lower conveying line 11, and are conveyed to the end close to the feeding slide plate 10, and then fall into the air-drying conveying cylinder 3 along the feeding slide plate 10.

[0048] Step 3: The colored plastic particles falling into the air-drying conveying cylinder 3 move upwards under the action of the main fan 31, and then fall into the upper conveying line 21 in the upper cleaning tank 2 through the upper outlet 30 under the action of the turning fan 32, and then move upwards under the action of the fixed feeding plate 211, and finally flow out through the finished product outlet 201, and the cleaning is completed.
