Description

Technical Field

[0001] The invention relates to the technical field of recycling and processing devices, in particular to a recycling and processing device for plastic masterbatch waste. Background Art

[0002] As the core raw material for the production of plastic products, plastic masterbatch is widely used in packaging, automobiles, electronic appliances, construction and other fields. The waste generated in its production process has high added value, but due to its complex composition, diverse forms and possible additives, masterbatches or impurities, it is difficult for traditional recycling technology to efficiently handle it. The existing recycling technology can be roughly divided into physical recycling and chemical recycling. Physical recycling mainly re-granulates through crushing, sorting, cleaning, melt extrusion and other steps. However, there are still some problems in the use of existing recycling devices, as follows:

[0003] Existing recycling devices usually use impeller rotation to crush waste materials, but the existing crushing structure is usually a simple impeller rotation. During the high-speed rotation crushing process, high-speed friction will be generated between the crushing impeller and the waste, generating a large amount of heat. In the existing crushing device, this heat cannot be dissipated in time and effectively, which leads to continuous accumulation of heat and continuous increase in the temperature inside the crushing chamber, causing subsequent waste to melt and stick to the impeller. This will cause the rotational load of the impeller to gradually increase, and the more waste sticking to the impeller, if it is not cleaned in time, it will seriously affect the crushing effect. Therefore, the existing device needs to be frequently shut down for inspection and maintenance, and it is impossible to effectively separate the lightweight impurities therein, resulting in the need for additional subsequent processing of the recycled waste, which increases the complexity of the entire processing. For this reason, we propose a plastic masterbatch waste recycling and processing device. Summary of the invention

DETAILED DESCRIPTION

[0034] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are only examples.

[0036] Compared with the prior art, the present application provides a primary crushing impeller 10 and a secondary crushing impeller 14 inside the outer cavity 1, which correspond to the low-speed crushing zone and the high-speed crushing zone respectively, and uses the primary crushing impeller 10 in the low-speed zone to preliminarily crush the material, and then uses the feeding component 11 to guide the material to the high-speed zone for fine crushing, which can not only increase the crushing effect, but also avoid the material getting stuck and causing the subsequent material to be unable to be effectively crushed. At the same time, combined with the airflow generated by the air intake component 3 at the bottom, the material in the high-speed crushing zone can be continuously lifted, thereby further increasing the crushing effect of the device on the material, and by providing a heat dissipation component 15 in the high-speed zone, the heat dissipation component 15 is internally arranged to make it have a temperature in the outer cavity 1. As the temperature rises, it will gradually expand to absorb heat, and its expansion degree increases with the increase of temperature, thereby increasing the area of ​​heat conduction, that is, increasing the heat dissipation effect. In this way, the device can automatically adjust the degree of heat dissipation in real time according to the change of temperature, ensuring that the temperature inside the device will not continue to rise. At the same time, combined with the air intake heat dissipation at the bottom, the flow of internal airflow is promoted, which greatly increases the thermal stability control effect of the device, thus avoiding the melting and bonding of waste materials caused by excessive temperature, and ensuring the continuous crushing effect of the secondary crushing impeller 14 in the high-speed zone. An impurity discharge component 2 is provided at the top of the outer cavity 1, which can also make light impurities be blown into it for separation and collection under the action of rotating centrifugal force and airflow, so as to improve the purity of the waste after treatment.

This can not only avoid the situation where the material is always accumulated in one crushing area and causes material blockage, but also improve the crushing effect of a single crushing area. The hexagonal structure setting can make the crushed material and light impurities radially thrown to the short side area of ​​the outer cavity 1 to achieve centrifugal separation, and when the material passes through the long side, it will approach the primary crushing impeller 10 and the secondary crushing impeller 14, so that the material rebounds into them after the impact and is crushed again, thereby greatly improving the crushing effect and efficiency.

The transmission wheel 12 is located inside the transmission chamber 113 and is rotated at intervals from the impeller, and is sealed and rotated with the end of the transmission chamber 113. In this way, when the first roller body 8 rotates rapidly, the transmission wheel 12 will be driven to rotate, and the rotation of the transmission wheel 12 will It will drive the liquid inside the transmission chamber 113 to rotate.
