Detailed Embodiments

[0020] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0021] Such as Figure 1As shown in the figure, a crushing device for the production of recycled polyester includes: a frame 1, a filter box 2, a vibrating screen 3, and a crushing box 4. An outlet 5 is provided on the frame 1, and the outlet 5 has a structure that is larger at the top and smaller at the bottom to facilitate the aggregation of materials.

[0022] As Figure 2 shown, the filter box 2 is fixedly arranged on the frame 1 and is correspondingly arranged above the outlet 5. At the same time, an installation space is left between the filter box 2 and the frame 1 to facilitate the installation of other structures. The installation space is formed by the opening of the filter box 2. When the materials are filtered, they can fall into the outlet 5 for discharging.

[0023] The vibrating screen 3 is inclined and arranged inside the filter box 2 and is located above the outlet 5. The vibrating screen 3 is provided with filter holes to filter out larger non-compliant fragments.

[0024] As Figure 3 and Figure 4 shown, two connecting plates 6 are arranged at the bottom of the vibrating screen 3. The two connecting plates 6 are respectively arranged near both sides of the vibrating screen 3. An installation plate 7 that is perpendicular to the connecting plate 6 and extends outward from the filter box 2 is arranged at the bottom of the connecting plate 6. The installation plate 7 is connected to the top of the frame 1 through an elastic member 8 in the installation space. A vibrating motor 9 is arranged on the connecting plate 6. The vibrating screen 3, the connecting plate 6, and the installation plate 7 are not in contact with the filter box 2 and are only installed on the frame 1 through the elastic member 8, so as to ensure that the overall shaking of the equipment will not be caused under the action of the vibrating motor 9.

[0025] Preferably, to ensure the structural stability, at least two installation plates 7 are arranged at the bottom of the connecting plate 6, and at least two elastic members 8 are arranged at the bottom of each installation plate 7. Among them, the elastic member 8 is preferably a spring. At the same time, a number of reinforcing inclined plates 19 are arranged between the installation plate 7 and the connecting plate 6 to improve the structural strength and meet the vibration requirements.

[0026] Both ends of the two connecting plates 6 are connected by a closing plate 20 to form an annular closed structure below the vibrating screen 3, which can guide the fragments to fall and reduce the splashing of the fragments.

[0027] As Figure 2 and Figure 3 shown, a material distribution port 10 is provided on the side of the filter box 2. The material distribution port 10 is correspondingly arranged at the inclined lower end of the vibrating screen 3 to facilitate the movement of non-compliant fragments to the material distribution port 10. A conveying pipe 11 is arranged outside the material distribution port 10, and an inclined material distribution plate 12 is arranged inside. The other end of the conveying pipe 11 is communicated with the bottom of a conveying cylinder 13 arranged on the frame 1. The material distribution plate 12 is located below the vibrating screen 3 and is used to catch the fragments falling from the vibrating screen 3 and guide the fragments to the material distribution port 10.

[0028] The crushing box 4 is arranged above the filter box 2. A crushing roller 14 is arranged inside it, an inlet 15 is opened at the top, and the bottom discharge end is placed above the vibrating screen 3.

[0029] As Figure 1 shown, the conveying cylinder 13 is vertically arranged, with a discharge channel 16 provided at the top, and the end of the discharge channel 16 is arranged above the feed inlet 15. A spiral conveying blade 17 is arranged inside the conveying cylinder 13, and the spiral conveying blade 17 is driven by a driving motor 18 arranged above the conveying cylinder 13. When the debris is fed into the conveying cylinder 13 through the discharge port 10 and the conveying pipe 11, the debris is driven to rise under the action of the spiral conveying blade 17 until it is discharged through the discharge channel 16, and then falls into the crushing box 4 through the feed inlet 15.

[0030] During operation: The waste plastic bottles are fed into the crushing box 4 through the feed inlet 15, fall to the filtering box 2 after being crushed by the crushing roller 14, and are divided into compliant debris and non-compliant debris after being filtered by the vibrating screen. The compliant debris continues to fall to the discharge port 5 for discharge, and the non-compliant debris moves obliquely downward along the vibrating screen 3 to the material distribution port 10, is sent to the conveying cylinder 13 through the material distribution port 10, and is sent back to the crushing box 4 by the conveying cylinder 13 for re-crushing until it is compliant.

[0031] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field based on the concept of the present invention through logical analysis, reasoning, or limited experiments on the basis of the prior art shall fall within the protection scope determined by the claims.
