Embodiment 1

[0044] Such as figure 1 As shown, a device for on-site processing of waste plastics is used for processing medical waste plastics. It includes crushed material bin 11, dechlorination chamber 12, high temperature cracking chamber 13, gas collection bin 14 and slag bin 15. A shredder 111 is provided at the feed inlet of the crushed material bin 11 , and a pusher paddle 112 and a cone conveying screw 115 are arranged in the crushed material bin 11 . The shredder 111 is used to shred medical waste plastics into plastic particles. The shredder 111 of this embodiment includes a feed hopper 1111, a feed hopper cover plate 1112 and a pulverizing cutter (not shown in the figure) driven by a first motor 1113, and the pulverizing cutter is arranged on the bottom of the feeding hopper 1111. lower end. The dechlorination chamber 12 communicates with the end of the crushed material bin 11, and there is a screw feeding mechanism 121 inside it, which is used to receive the materials in the...

Embodiment 2

[0057] Such as figure 2 As shown, the equipment for processing waste plastics on site is realized, and the equipment is used for processing ordinary waste plastics. The difference from the equipment in Embodiment 1 is that this equipment reduces the second thermal jacket 114 and the water tank 15 on the outside of the broken material bin 11, and the feed hopper cover plate 1111 on the shredder 111 can be removed at the same time. Since the second thermal jacket 114 is reduced, the regulating valve between the first thermal jacket and the second thermal jacket for regulating the high-temperature hot air is also removed. At the same time, those skilled in the art can determine whether to open a liquid outlet at the bottom of the scrap bin according to whether the processed waste plastics contain liquid. the rest with figure 1 same.

Embodiment 3

[0059] Use the equipment for treating waste plastics in situ of the above-mentioned embodiment 1 to process medical waste plastics, the specific steps are as follows:

[0060] Step 1, the medical waste plastics are crushed by the shredder 111 and sent to the crushing bin 11 with the second heating jacket 114, and the crushed medical waste plastic particles are heated at a temperature of 100-200°C and a pressure of 0.3-0.6MP Under certain conditions, the entire crushed material bin 11 is filled with steam, and the high-temperature gas is used for high-temperature disinfection. Use pusher paddle 112 to stir continuously during this process. The liquid brought in by medical waste plastics is heated in the crushing bin to become high-temperature steam. After the disinfection is completed, it is sent into the water tank 15 through the pipeline on the shredder 111 to condense into liquid, and then discharged or the water tank 15 is condensed into liquid. The liquid is transported t...

Abstract

The invention provides equipment for realizing on-the-spot disposal of medical waste plastics and a treatment method thereof, wherein the equipment comprises a crushed material cabin, a dechlorination cavity, a high-temperature cracking cavity, a gas collecting cabin and a slag cabin, wherein the high-temperature cracking cavity communicates with a discharging opening of the dechlorination cavity; the gas collecting cabin is arranged at the upper part of the high-temperature cracking cavity and is used for collecting combustible gas generated through decomposition of materials in the high-temperature cracking cavity. The treatment method comprises the steps that the medical waste plastics are crushed by a chopping machine and are then conveyed to the crushed material cabin; the treated medical waste plastics are conveyed into the dechlorination cavity to be subjected to dechlorination treatment; the medical waste plastics after dechlorination are conveyed into the high-temperature cracking cavity for cracking; carbon black after cracking is conveyed to the slag cabin. The equipment size is small; the investment is little; the medical waste plastics can be treated in hospital on the spot; the supervision lack and the secondary pollution caused in the medical waste transportation process are avoided; the equipment and the treatment method are suitable for large-scale popularization and application. When the equipment is used for treating the medical waste plastics, the innocent treatment of the medical wastes and the resource cyclic utilization are truly realized.

Description

technical field [0001] The invention belongs to the technical field of waste plastic treatment, and in particular relates to a device for realizing on-site treatment of waste plastic and its application. Background technique [0002] According to the "Regulations on the Management of Medical Waste" of the State Council, medical waste refers to directly or indirectly infectious, toxic and other hazardous waste produced by medical and health institutions in the course of medical treatment, prevention, health care and other related activities. With the rapid development of economies around the world and the continuous improvement of people's living standards, global health has been greatly developed, and the growth of medical waste is also very alarming. Relevant data show that each bed in our country’s hospitals produces an average of 1,000 grams of waste per day. The daily medical waste of a medium-sized city is about 40 to 70 tons, and the annual medical waste of a province ...
