Embodiment Construction

[0015] The present invention will be further described below in conjunction with examples and accompanying drawings. It should be noted that the following embodiments are only illustrative, and are not intended to limit the present invention.

[0016] like figure 1 As shown, in the recycling method of plastics from garbage of the present invention, the first step includes sorting out plastics from garbage. Using a garbage sorting machine, most of the plastics can be screened out by manual primary selection and wind selection of the garbage sorting machine. Including various plastic packaging bags, beverage bottles.

[0017] The second step is cleaning. Since the plastic bags sorted out from the garbage contain a lot of dirt such as silt, they cannot be directly used. Therefore, firstly, the sorted plastic bags are placed in a box with multiple sieve holes at the bottom and around them, and then The box is immersed in a water pool, and the box is repeatedly shaken to roughly...

Abstract

The invention discloses a garbage recovery plastic regeneration method. The garbage recovery plastic regeneration method comprises the following steps: (1) plastic is firstly sorted from garbage; (2) cleaning: sorted plastic bags are positioned in a box provided with multiple screen holes in the bottom and the periphery; and then, the box is dipped in a pool, and is repeatedly oscillated; (3) the cleaned plastic is drained off, and is dried by hot air; (4) the plastic is heated to reach a molten state; (5) a mold is prepared; and a reinforcement bracket is arranged in the mold; and (6) the plastic in the molten state is put in the mold for synchronous pressurization, and the outer periphery of the mold is cooled by water when pressurizing, so that the plastic can be pressurized during cooling; and after the plastic is cooled to reach a certain temperature, a finished product is taken out from the mold. The plastic extracted from the garbage is adopted as municipal well lids, sewer grids and the like; and the plastic well lids manufactured with few reinforcement brackets as skeletons are better in pressure resistance, and have the effects of environmental protection, easiness in manufacturing and low cost.

Description

technical field [0001] The invention relates to a method for recycling plastics, in particular to a method for recycling plastics from garbage. Background technique [0002] The development of the plastics industry has brought great benefits to mankind, but it has left endless troubles, namely "white pollution". Since there are plastic products, old plastics are inevitably produced, and as time goes by, more new raw materials are put into use, which makes waste plastics rise sharply. Because waste plastics are not easy to age and degrade at room temperature, white pollution is increasing day by day, causing serious damage to the ecological environment. At present, after waste plastics are recycled, they are usually used to make recycled plastic pellets. This results in poor recycling and environmental pollution. [0003] However, the recycling rate of plastics in my country is extremely low, and there are a lot of plastics in a large amount of domestic waste, but they can...
