Description

Technical Field

[0001] The utility model relates to the technical field of polymer material melting, in particular to a polymer material recycling melting device. Background Art

[0002] Polymer materials are materials composed of compounds with relatively high molecular weight. Such as natural rubber, cotton, human organs, etc. The same is true for artificially synthesized chemical fibers, plastics and rubbers. Generally speaking, polymers that are widely used in life and have formed an industrial production scale are called general polymer materials. In life, a large amount of waste plastics and waste rubber will be generated. These waste plastics and waste rubber need to be melted during recycling. Regarding the existing public patent "A waste raw material melting device for plastic recycling (publication number: CN216299839U), this waste raw material melting device for plastic recycling dumps the waste plastic into the feed hopper and crushes the waste plastic through two crushing rollers. The crushed plastic falls onto the baffle through the filter screen. At this time, the burner drives the plastic to melt, and the filter screen plays a role in filtering. The effect is that some larger plastics are continuously crushed until the size fits the filter screen, and the plastic is crushed to a suitable size. The motor drives the stirring rod to rotate, and slightly stirs the plastic when it melts. Compared with traditional equipment, this equipment ensures the stable melting of the plastic and prevents the burner from being driven for a long time due to the large size of some plastics, saving costs. There are certain shortcomings in the use process. Waste plastics, rubber and other polymer materials will produce irritating and harmful substances when recycled and melted. If they are not handled effectively, they will pollute the air and endanger the health of workers, making the melting equipment less environmentally friendly and not conducive to long-term use.

[0021] Working principle: When melting plastic and rubber, pungent odor and smoke will be generated. By starting the vacuum pump 3, the first vacuum frame 4 will generate suction, and then through the connection of the connecting pipe 5, the second vacuum frame 8 will also generate suction. Then the vacuum port of the first vacuum frame 4 will suck the gas generated in the melting furnace 1, and then the vacuum port of the second vacuum frame 8 can suck the gas leaked from the crushing box 2. The generated gas will enter the filter box 6 through the gas pipe 7.

[0023] Preferably, a baffle 18 is fixedly mounted on the lower inner wall of the crushing box 2 .

[0024] Working principle: waste rubber and plastic are put into the crushing box 2, the first motor 12 drives the crushing roller 11 to rotate, and the gear 13 is set to make the other crushing roller 11 rotate. The two crushing rollers rotate relative to each other to crush the rubber and scraps.
