detailed description

It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

As shown in Figures 1 to 2, a pneumatic separation and dust removal system for rubber powder transportation in this embodiment includes a main frame 4, a rubber powder transportation pipeline 1, and a fan 5 for providing a power source for rubber powder transportation , and two No. 1 air chambers 2 and No. 2 air chambers 6 for sorting rubber powders with different diameters. The air chambers communicate with the rubber powder delivery pipeline 1.

No. 1 air chamber 2 is composed of a lower opening silo 11 and a dial door 3 for unloading. The dial door is located at the discharge port of the lower opening silo. The dial door 3 enables the system to complete the glue under the pressure maintaining state material delivery. The No. 2 air chamber is composed of a lower opening silo 11 and a trolley 10 for storing dust and impurities, and the trolley is located at the discharge port of the lower opening silo. The No. 1 air chamber 2, the fan 5 and the No. 2 air chamber 6 are connected in sequence.
