[0029] In the following, the present invention will be further described in conjunction with the drawings and specific implementations. It should be noted that, provided that there is no conflict, the following embodiments or technical features can be combined to form new embodiments. .
[0030] Such as Figure 1-3 As shown, in order to realize automatic separation and recycling of plastic products, the present invention provides a separation sedimentation tank. The separation sedimentation tank includes a separation tank main body 10, a collection device 20 arranged at the lower part of the separation tank main body 10, and a supporting separation tank. The main body 10 and the support 30 of the collecting device 20, the collecting device 20 communicates with the inside of the separation tank main body 10, and is used to collect the sediment after the separation of the plastic mixture in the separation tank main body 10; one end of the separation tank main body 10 is provided with a feed port 11 , Used to put the plastic mixture that needs to be separated and recycled into the separation tank body 10, the other end of the separation tank body 10 is provided with a storage cavity 12 for collecting the floating material after the separation of the plastic mixture; the separation tank body 10 is equipped with It is used for separating the plastic mixture 13 and the shifting component 14 for shifting the floating material.

[0031] During the use of the present invention, the plastic mixture is transported from the outside of the separation sedimentation tank through the feed port 11 into the separation tank body 10 through the production line, and the plastic mixture is dispersed from the separation tank body 10 through the distributing assembly 13 to make the plastic mixture Evenly dispersed in the main body of the separation tank 10 and can be immersed in the separation liquid, and then the plastic mixture is drifting towards one end of the storage cavity 12, the distributing component 13 separates the plastic mixture, and separates the floating material in the plastic mixture and The sediment is separated, the sediment sinks into the bottom of the separation tank main body 10 and is collected and recovered by the collection device 20, while the float continues to drift forward and is finally transferred to the storage cavity 12 by the shift component 14 for collection. In this process, because the concentration of the separation liquid will change with the process, it is necessary to adjust the concentration of the separation liquid. The previous separation sedimentation tank needs to discharge all the separation liquid in the separation tank every time it is used. And re-inject the separation liquid with the required concentration, which is expensive and also affects the recovery efficiency. The present invention uses the concentration adjustment mechanism 15 to detect and supplement the separation liquid concentration in the separation tank body 10 in real time, so that the separation liquid even after a long time The concentration of the separation process can also be guaranteed, and finally the automatic separation and collection of plastic waste for a long time can be realized.
