Technical Field

[0001] This utility model belongs to the field of plastic recycling and processing, and in particular relates to an environmentally friendly plastic crushing equipment. Background Technology

[0002] Plastic recycling refers to the process of collecting, sorting, processing, and reprocessing waste plastics to restore their usability. It is not only a key means of reducing environmental pollution but also an important pathway for resource recycling. Crushing is a crucial pre-treatment step in plastic recycling.

[0003] The plastic recycling and crushing process often generates dust containing microplastics. This dust enters the external environment, directly threatening workers' health and causing microplastics to spread into the environment, resulting in environmental pollution. Simultaneously, the friction generated during equipment processing can cause the plastic to release harmful gases, further exacerbating environmental pollution. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0028] Please see Figures 1 to 3 This utility model embodiment provides an environmentally friendly plastic crushing device, comprising:

[0029] The machine housing 1 has a feed inlet 11 at its upper end, and a guide plate 12 is fixedly installed inside the machine housing below the feed inlet 11. The bottom of the machine housing 1 is also configured as an open structure, and a discharge plate 13 is fixedly installed inside the machine housing.

[0030] Crushing component 2 is used for crushing and recycling plastics;

[0031] Dust removal component 3, used to remove dust and exhaust gas generated during the crushing process, includes:

[0032] The dust collection box 31 is filled with processing liquid and is fixedly installed on the side of the casing 1. Its side is fixedly connected to an external air extraction device through an air extraction pipe 311. A liquid outlet pipe 313 is fixedly opened at its bottom. The liquid outlet pipe 313 is controlled to be opened and closed by a control valve fixedly installed on it.

[0033] Multiple dust removal pipes 33 are horizontally arranged inside the housing 1. Multiple air extraction holes 331 are fixedly opened on their sides. Their ends penetrate the housing 1 and extend to the outside of the housing 1, where they are fixedly connected to multiple connecting pipes 32 fixedly installed on the side of the housing 1. The dust removal pipes 33 are connected to the inside of the dust removal box 31 through the connecting pipes 32.

[0034] In practical application, recycled plastic is fed into the housing 1 through the feed inlet 11. After being guided and collected by the guide plate 12, the recycled plastic is crushed by the crushing component 2. While the crushing component 2 is crushing the plastic, an external high-pressure air extraction device extracts air through the extraction pipe 311. Under the action of negative pressure, dust and exhaust gas in the housing 1 are drawn in through the extraction hole 331 and discharged into the dust collection box 31 through the dust removal pipe 33 and the connecting pipe 32. The dust and exhaust gas are treated by the adhesion and absorption of the liquid in the dust collection box 31.

[0035] In this embodiment, the dust removal component 3 draws in the dust and exhaust gas generated inside the casing 1 during the processing of the crushing component 2, and uses the liquid in the dust removal box 31 to adhere and absorb it. Compared with existing plastic crushing equipment, this effectively controls and treats dust and exhaust gas, avoiding environmental pollution. At the same time, the adhesion of dust to the liquid in the dust removal box 31 can also achieve dust recycling, improving the plastic recycling rate.

[0036] Please see Figures 2 to 4 In a preferred embodiment of this utility model, the crushing component 2 includes:

[0037] Two crushing rollers 22 are horizontally rotatable inside the housing 1 and located below the guide plate 12 via a central shaft. Crushing teeth are arranged in annular staggered arrangement on the outer side of the two crushing rollers 22.

[0038] Two crushing motors 21 are fixedly installed on the side of the casing 1, and their power output ends are fixedly connected to the central shafts of the two crushing rollers 22 respectively.

[0039] In practical applications, this embodiment uses two crushing motors 21 to drive two crushing rollers 22 to rotate in parallel and opposite directions, thereby achieving the crushing of recycled plastics through staggered crushing teeth.

[0040] Please see Figure 3 and Figure 4 In another preferred embodiment of the present invention, the crushing roller 22 is configured as a hollow structure, with multiple air extraction channels 221 evenly distributed in a ring on its outer side.

[0041] Furthermore, the dust removal assembly 3 also includes a second connecting pipe 34. The shaft end of the crushing roller 22 extends movably to the outside of the housing 1 and is rotatably connected to the second connecting pipe 34 via a movable seat 341. The crushing roller 22 is connected to the inside of the dust removal box 31 via the second connecting pipe 34.

[0042] In practical applications, this embodiment, through the connection pipe 34 and the hollow crushing roller 22, allows for the direct extraction of dust and exhaust gas generated during the crushing process via the extraction channel 221, enabling rapid and efficient treatment of dust and exhaust gas.

[0043] Please see Figure 3 In another preferred embodiment of this utility model, a filter plate 314 is also fixedly installed inside the dust collection box 31 for filtering the liquid inside the dust collection box 31.

[0044] Furthermore, an overflow valve 315 is fixedly installed on the side of the dust collector 31. The overflow valve 315 is installed at a height lower than the lowest point of the dust collector pipe 33. The overflow valve 315 connects the inside and outside environment of the dust collector 31 in one direction and is used to limit the water level inside the dust collector 31.

[0045] In practical application, as the equipment processes the dust for a long time, a large amount of dust will accumulate in the dust collection box 31, causing the liquid level in the dust collection box 31 to rise. After being filtered by the filter plate 314, the dust is kept at the bottom of the dust collection box 31. The water level in the dust collection box 31 is controlled by the overflow valve 315 to prevent the water level in the dust collection box 31 from being too high and flowing back into the casing 1 through the dust collection pipe 33 under the principle of communicating vessels, thus polluting the environment inside the casing 1.

[0046] Please see Figure 2 In another preferred embodiment of this utility model, the dust collection box 31 is fixedly connected to an external infusion device through an inlet pipe 312 fixedly opened at the top, and the inlet pipe 312 is controlled by a control valve fixedly installed thereon.

[0047] In practical application, this embodiment uses the liquid inlet pipe 312 to input liquid into the dust collector 31, and the suction pipe 311 to discharge the liquid from the dust collector 31, thereby achieving liquid replenishment and replacement. The liquid inlet pipe 312 can also be used to rinse the dust collector 31, making it convenient to clean the dust collector 31.

[0048] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
