[0026] The present invention is described in detail with reference to the accompanying drawings in the embodiments of the present invention.

[0027] A method for processing modified plastic particles comprises the following steps:

[0028] Step 1: Prepare the waste plastics, waste tire particles and various additives for recycling;

[0029] Step 2: Mixing the waste plastics, waste tire particles and various additives and re-granulating them to obtain modified plastic particles;

[0030] Step 3: Adding the prepared modified plastic particles into the processing system;

[0031] Step 4: Clean and deodorize the modified plastic particles;

[0032] Step 5: Take out the modified plastic particles and dry them.

[0033] See also Figure 2-4 , showing a schematic diagram of an embodiment of the present invention capable of cooling and deodorizing just-made modified plastic particles, further,

[0034] The processing system includes a cleaning tank 101, on which a plurality of springs 203 are welded and fixedly connected, on which a filter basin 201 is welded and fixedly connected, on which two cylinders 103 are bolted and fixedly connected, on which a movable end of the two cylinders 103 is bolted and fixedly connected to a fixed seat 401, on which a connecting pipe 306 is rotatably connected via a bearing, on which the lower end of the connecting pipe 306 is bolted and fixedly connected to an air guide box 302, on which the lower end of the air guide box 302 is bolted and fixedly connected to a pressure plate 301, and on the lower end of the cleaning tank 101 a drain pipe 102 is welded and fixedly connected.

[0035] When using the device, first add cold water and deodorant into the cleaning pool 101, then the staff adds the newly prepared modified plastic particles into the filter basin 201, and controls the moving ends of the two cylinders 103 to contract, thereby driving the fixed seat 401 to descend, so that the fixed seat 401 drives the connecting pipe 306 to be inserted into the cold water, and then the connecting pipe 306 drives the pressure plate 301 to press the filter basin 201 into the cold water, thereby playing a role in cleaning and cooling the modified plastic particles, accelerating the shaping of the plastic particles, and the cold water and deodorant can remove the irritating odor generated after the modified plastic particles are prepared, thereby achieving the effect of reducing the harm to the health of the staff, and finally controlling the connecting pipe 306 to drive the pressure plate 301 to rotate, so that the modified plastic particles flow in the water, enhancing the cleaning and cooling effects, and when the filter basin 201 rises, the filter basin 201 can drain the water between the modified plastic particles, and can also filter out the fine debris in the modified plastic particles, thereby improving the quality of the modified plastic particles.

[0036] The drain pipe 102 is provided with a valve for draining the water in the cleaning pool 101 .

[0037] See also Fig. 9 , showing a schematic diagram of an embodiment of the present invention capable of accelerating the fluidity of modified plastic particles, further,

[0038] A plurality of air pipes 303 are welded and fixedly connected to the air guide box 302 . The air guide box 302 is an internal hollow structure. The plurality of air pipes 303 are connected to the interior of the air guide box 302 . Each air pipe 303 is provided with a plurality of air holes.

[0039] The staff connects the connecting pipe 306 to an external fan to continuously pump air into the connecting pipe 306, and then the air enters the air guide box 302 and is sprayed into the cold water through multiple air pipes 303. In order to prevent the plastic particles from sinking to the bottom after entering the cold water, resulting in low fluidity, the connecting pipe 306 drives the multiple air pipes 303 to rotate to stir the cold water, thereby increasing the fluidity of the cold water, making it difficult for the modified plastic particles to sink to the bottom and able to flow with the water flow. At the same time, the multiple air pipes 303 spray a large number of bubbles outward. The impact force of the rising bubbles can drive the modified plastic particles to roll in the cold water, thereby improving the cleaning efficiency. The violent movement of the modified plastic particles can cause some of the modified plastic particles that are connected during preparation to break and separate, thereby further improving the overall quality of the modified plastic particles.

[0040] See also Fig. 9 , shows a schematic diagram of an embodiment of the present invention that can further improve the effect of continuous particle separation, and further,

[0041] A split piece 304 is rotatably connected between each of the air pipes 303 and the connecting pipe 306 via a bearing, and a torsion spring 305 is welded and fixedly connected between each split piece 304 and each of the air pipes 303 .

[0042] When the connecting tube 306 drives the multiple air tubes 303 to rotate, it drives the multiple split pieces 304 to rotate around the axis of the connecting tube 306, so that the modified plastic particles frequently collide with the multiple split pieces 304, which can split the connected plastic particles, thereby further improving the effect of separating the connected particles.

[0043] When multiple split pieces 304 collide with modified plastic particles frequently, the split pieces 304 will rotate and tilt on the air pipe 303, and can automatically reset under the action of the torsion spring 305, thereby increasing the contact range with the modified plastic particles and improving processing efficiency.

[0044] See also Figure 7 , shows a schematic diagram of an embodiment of the present invention capable of preventing plastic particles from splashing, and further,

[0045] A baffle 202 is fixedly connected to the filter basin 201 by means of bolts.

[0046] The shield 202 serves to block the plastic particles and prevent the plastic particles from splashing out due to violent movement.

[0047] See also Fig.10 , shows a schematic diagram of an embodiment of the present invention that can realize the lifting of the filter basin 201, further,

[0048] The upper part of the connecting tube 306 is threadedly connected to a lifting plate 402, and an internal thread for matching the connecting tube 306 is provided on the lifting plate 402. A sliding rod 408 is fixedly connected to the fixing seat 401 by bolts. The lifting plate 402 is slidably connected to the sliding rod 408, and a hole for matching the sliding rod 408 is provided on the lifting plate 402. Two contact rods 405 are fixedly connected to the lifting plate 402 by bolts.

[0049] The staff controls the connecting pipe 306 to rotate back and forth. When the connecting pipe 306 rotates forward, the lifting plate 402 descends, and the lifting plate 402 drives the two contact rods 405 to press the filter basin 201 down. When the connecting pipe 306 is reversed, the lifting plate 402 rises, and multiple springs 203 drive the filter basin 201 to automatically reset. The connecting pipe 306 rotates back and forth in this way, thereby realizing the function of reciprocating lifting and lowering of the filter basin 201 in cold water, which can further prevent the modified plastic particles in the filter basin 201 from sinking to the bottom.

[0050] See also Fig.10 , shows a schematic diagram of an embodiment of the present invention for facilitating the connection of the connecting pipe 306 with the fan, and further,

[0051] A hose 407 is rotatably connected to the connecting pipe 306 via a bearing.

[0052] The hose 407 is used to connect to the fan, thereby facilitating the flow of air into the connecting pipe 306 .

[0053] See also Figure 6-10 , shows a schematic diagram of driving the connecting pipe 306 to rotate according to the present invention, and further,

[0054] The connecting pipe 306 is fixedly connected to the driven wheel 403 via a key, the lower end of the fixing seat 401 is fixedly connected to the first motor 406 via bolts, the output shaft of the first motor 406 is fixedly connected to the driving wheel 404 via a coupling, and the driving wheel 404 is meshed with the driven wheel 403 for transmission.

[0055] The first motor 406 is started, the first motor 406 drives the driving wheel 404 to rotate, the driving wheel 404 drives the driven wheel 403 to rotate, and the driven wheel 403 drives the connecting pipe 306 to rotate.

[0056] See also Figure 4-8 , showing the intention of the embodiment of the present invention in which the modified plastic particles can be dried, further,

[0057] A second motor 501 is fixedly connected to the cleaning tank 101 by bolts, an eccentric wheel 502 is fixedly connected to the output shaft of the second motor 501 by bolts, a push-pull rod 503 is rotatably connected to the eccentric rod of the eccentric wheel 502 through a bearing, the lower end of the filter basin 201 is fixedly connected to the limiting rod 204 by bolts, the other end of the push-pull rod 503 is slidably connected to the limiting rod 204, and the other end of the push-pull rod 503 is provided with a hole for cooperating with the limiting rod 204.

[0058] When the modified plastic particles are cleaned, the second motor 501 is started, and the second motor 501 drives the eccentric wheel 502 to rotate, and the eccentric wheel 502 drives the push-pull rod 503 to push and pull the limit rod 204, so that the filter basin 201 can be pushed and pulled, and under the action of multiple springs 203, the filter basin 201 is shaken, so that the plastic debris in the filter basin 201 can be screened out, and at the same time, the staff makes the multiple air pipes 303 spray hot air, which can achieve the effect of drying the modified plastic particles and improve the processing efficiency.

[0059] The push-pull rod 503 serves to limit the filter basin 201 . When the filter basin 201 is raised or lowered, the limit rod 204 can slide on the push-pull rod 503 to ensure that the filter basin 201 moves vertically up and down.
