[0001] The present invention relates to the field of plastic recycling, and in particular to a recycled plastic crushing device and method. Background Art

[0002] Plastic recycling refers to the process of reusing discarded or used plastic products, which has multiple advantages such as reducing resource consumption, reducing environmental pollution and optimizing resource utilization. The recycled plastic needs to be crushed to facilitate subsequent melting processing.

[0020] The present invention is described in detail with reference to the accompanying drawings in the embodiments of the present invention.

[0021] See also Figure 3-7 ,

[0022] A recycled plastic crushing device includes a processing barrel 101, which is fixedly connected to two cylinders 104 by bolts, the movable ends of the two cylinders 104 are fixedly connected to a crushing barrel 201 by bolts, a feeding screw 204 is rotatably connected to the crushing barrel 201 by a bearing, a conical cover 301 is welded to the lower end of the feeding screw 204, a plurality of oblique blades 302 are fixedly connected to the surface of the conical cover 301, the upper end of the crushing barrel 201 is fixedly connected to a driving motor 202 by bolts, and the feeding screw 204 is fixedly connected to the output shaft of the driving motor 202 by a coupling.

[0023] When using the crushing device, the staff first adds the recycled plastic into the crushing barrel 201, and uses the driving motor 202 to drive the feeding screw 204 to rotate, thereby driving the plastic to be transported downward, so that the plastic is accumulated at the bottom of the crushing barrel 201. At this time, the plastic is between the spiral blades of the feeding screw 204 and the conical cover 301. The feeding screw 204 rotates to compress the plastic, thereby reducing the volume of the plastic, making it easier to continuously add plastic to the crushing barrel 201 and improve processing efficiency. Under the action of pressure, the plastic can be pressed against the conical cover 301. While the feeding screw 204 drives the conical cover 301 to rotate, the multiple oblique blades 302 on the conical cover 301 cut the plastic, thereby realizing the function of crushing the plastic. The above structure can realize the function of compressing and crushing the plastic, saving space and improving crushing efficiency, and the feeding screw 204 can achieve a continuous crushing effect.

[0024] The processing barrel 101 is used to contain water, and the broken plastic falls into the processing barrel 101, thereby facilitating the subsequent cleaning of the plastic fragments.

[0025] See also Figure 6 ,

[0026] A plurality of anti-slip bars 303 are fixedly connected to the lower end of the crushing cylinder 201 by means of bolts.

[0027] The multiple anti-slip bars 303 can promote the crushing of plastic. When the plastic is transferred to the bottom of the crushing barrel 201, the plastic will be stuck by the multiple anti-slip bars 303, thereby preventing it from continuing to move under the action of the conveying screw 204, thereby facilitating cutting and crushing by the multiple oblique blades 302.

[0028] See also Figure 5-6 ,

[0029] A rotating disk 304 is welded on the conical cover 301 , and a plurality of leakage slots 305 are formed on the rotating disk 304 .

[0030] The turntable 304 is used to hold the broken plastic fragments. When the plastic is broken, it is discharged into the turntable 304. Since the turntable 304 is provided with a plurality of leakage grooves 305, the water in the treatment cylinder 101 can enter the turntable 304 through the plurality of leakage grooves 305, so that the plastic fragments can be soaked. At the same time, the turntable 304 is driven to rotate by the conical cover 301, so that the plastic fragments can be cleaned. There is no need to transfer and clean the broken plastic fragments, making the overall processing procedure more coherent.

[0031] See also Figure 5-6 ,

[0032] A feed inlet 203 is provided at the upper end of the crushing cylinder 201 , and the feed inlet 203 is used to fill the crushing cylinder 201 with plastic, thereby achieving the effect of continuously crushing the plastic.

[0033] See also Figure 2 ,

[0034] A valve 103 is installed at the lower end of the treatment cylinder 101 . When the plastic is cleaned, the staff opens the valve 103 to discharge the sewage, while the plastic fragments will be isolated in the turntable 304 .

[0035] See also Figure 8 ,

[0036] A rotating tube 403 is rotatably connected to the crushing cylinder 201 via a bearing, and a plurality of groups of brushes 405 are fixedly connected to the rotating tube 403 via bolts. A baffle 102 is welded to the upper end of the processing cylinder 101 .

[0037] When the plastic is cleaned, the moving ends of the two cylinders 104 are controlled to extend, thereby driving the crushing barrel 201 to rise, and the crushing barrel 201 drives the turntable 304 to separate from the liquid surface, so that the water can be drained, and the brush 405 on the rotating tube 403 contacts the inner wall of the turntable 304, and the turntable 304 is controlled to rotate at the same time, so that the remaining water in the plastic can be thrown out by the centrifugal effect, thereby realizing the dehydration function of the plastic. In the process of dehydration, the rotating tube 403 is controlled to rotate, and then the inner wall of the turntable 304 can be cleaned by multiple groups of brushes 405, so as to avoid the centrifugal force causing the plastic to adhere to the inner wall of the turntable 304 for a long time, affecting the dehydration effect.

[0038] The shield 102 serves to shield the sewage and prevent the sewage from being thrown out.

[0039] See also Figure 4 ,

[0040] There are multiple air holes 404 on the rotating tube 403. While clearing the inner wall of the turntable 304, the staff introduces hot air into the rotating tube 403, and the hot air is evenly discharged through the multiple air holes 404. At the same time, with the rotation of the turntable 304 itself, the multiple groups of brushes 405 can rotate to break up the plastic fragments, so that the hot air is evenly dispersed, thereby achieving the effect of evenly drying the plastic.

[0041] See also Figure 8 ,

[0042] The upper end of the rotating tube 403 is rotatably connected to a connecting tube 402 via a bearing. The connecting tube 402 is used to be connected to a hot air blower so as to transmit hot air into the rotating tube 403 when the rotating tube 403 rotates.

[0043] See also Figure 1-4 ,

[0044] The rotating tube 403 and the material conveying screw 204 are both fixedly connected with pulleys 401 through keys, and the two pulleys 401 are connected through a synchronous belt.

[0045] While the material conveying screw 204 is rotating, the two pulleys 401 and the synchronous belt can cooperate to drive the rotating tube 403 to rotate, thereby achieving the effects of conveying and drying the plastic at the same time, without the need to control the rotating tube 403 separately, thereby simplifying the operation.

[0046] A method for recycling a plastic crushing device, the method comprising the following steps:

[0047] Step 1: Add the recycled plastic into the crushing cylinder 201, and use the driving motor 202 to drive the conveying screw 204 to rotate and drive the plastic downward, so that the plastic is accumulated at the bottom of the crushing cylinder 201;

[0048] Step 2: The conveying screw 204 drives the conical cover 301 to rotate, and at the same time, the multiple oblique blades 302 on the conical cover 301 cut the plastic;

[0049] Step 3: After the plastic is crushed, it is discharged into the rotating disk 304. The water in the treatment cylinder 101 enters the rotating disk 304 through multiple drain grooves 305. The conical cover 301 drives the rotating disk 304 to rotate to clean the plastic fragments.

[0050] Step 4: Control the moving ends of the two cylinders 104 to extend, the crushing barrel 201 drives the turntable 304 to separate from the liquid surface, and then control the turntable 304 to rotate, and use the centrifugal effect to throw out the remaining water in the plastic to achieve the dehydration function of the plastic. During the dehydration process, the rotating tube 403 is controlled to rotate, and the inner wall of the turntable 304 is cleaned by using multiple groups of brushes 405;

[0051] Step 5: While the inner wall of the turntable 304 is being cleared, hot air is introduced into the rotating tube 403, and the hot air is discharged through the multiple air holes 404. At the same time, in conjunction with the rotation of the turntable 304 itself, the multiple groups of brushes 405 rotate to break up the plastic fragments and evenly dry the plastic.
