Description

1230099 V. Description of the invention (1) ----- [Technical Field of the Invention] The present invention relates to a method and a device for recovering soft plastic films in domestic garbage, especially a soft plastic film capable of quickly and efficiently collecting domestic garbage. Method and device. / [Previous technology] Since ancient times, the way to dispose of garbage is nothing more than landfilling and incineration. However, with the progress of society, the amount of garbage produced by people is also large, resulting in the need to landfill garbage with a large amount of land Moreover, if the protection engineering is not handled well, it is easy to cause further pollution of groundwater sources and soil; and by incineration, a large amount of air pollution will be generated. There are problems with groundwater sources and land pollution; and with the development of new towns, people pay more attention to the home environment and prolong the struggle against garbage dumps, which makes land that can be used as landfill less and less. It also causes waste disposal costs. increase. With the gradual depletion of the earth's resources, people have begun to attach importance to and cherish the limited earth resources. The recycling of the available materials in the garbage can not only effectively reduce the amount of garbage treated, but also reduce the pressure on the useful life of the landfill; more It can reduce people ’s consumption of the earth ’s resources. Therefore, resource recovery is a better way to temporarily reduce the pressure on garbage disposal. However, the current recycling equipment and technology cannot effectively classify mixed garbage. The focus is that the substances in domestic waste are too complicated, including toxic, non-toxic, large, small, dry, wet, soft, hard, light, heavy and heavy. First-class substances' cannot usually be effectively classified by mechanized equipment;

134-033TWP.ptd Page 5 1230099 V. Description of the invention (2) Classification method (personnel classification), once the mixed member is exposed to toxic substances (especially rubbish, etc.), the film is often thin, and it is time-consuming and troublesome. But plastic products in the waste recycling resources are mixed with disadvantages. The special collection method and device of the inventor's flexible plastic film may be due to the infection of the troublesome and toxic substances in the garbage with other human labors; moreover, in the largest process of garbage, they should be recycled together for the first reason The quality of the classification by the public, manual classification, and non-ideal plastic film garbage sticky pick-up sorting are due to the soft plasticity. This is a kind of classification method that is only a way of 'resorting resources or having a high error rate.' Including Baotou together, compared with the thin film and soft and unique material collection process of plastic film, it is easy to make plastic bags of thin plastic waste from recycled garbage. In the future, many other materials have been developed in light of this. After taking advantage of the softness and softness of the plastic in the water, it finally invented a method that uses the isolation, tileability, and water film to intercept and concentrate it. [Summary of the Invention] "The main plastic film of the present invention is made from life Separate from garbage; provide-a method that can effectively soften the present invention is m recovery method. The film is separated from domestic garbage Separate and concentrate the plastic knees effectively To achieve the above-mentioned purposes, the method of recycling and wearing of plastic film is to provide—a kind of domestic waste to make softness.

1230099 V. Description of the invention (6) Below the terminal, there is a medium-sized garbage collection box; In addition, the water channel is close to the terminal. 'There is a plastic film interception device that intercepts the plastic film in the water stream, and intercepts the plastic film. Between the terminal of the device and the water channel, a plastic film conveyor belt is set horizontally, so that the plastic film can be collected and treated by the recycler. Advantageously, the inside of the screen device is located near the terminal, and a blowing device is provided. The blowing device can blow air obliquely toward the surface of the screen device and the aqueduct. Water spray device that sprays water under the screen device. In the area of the early father's belt, the picks that rotate sideways protrude from the outer diameter of the rotary towards the front and the bottom of the sieve dial. Preferably, there are paddles with the dial mainly distributed on the arc of the rotating shaft. Preferably, the crochet gripping device, the loop of the conveyor belt, reverses and makes the terminal of the conveyor belt, and the surface of the conveyor belt has a direction toward the periphery of the conveyor to equally divide the distance of the picking wheel to pick the garbage conveyor belt. For the turning wheel, the rotation direction is bent and placed in the water flow in the "closed water flow direction," and the side is a plastic film wheel. The picking wheel is mainly a curved piece distributed in the rotation direction of the rotation shaft. Between the grid-connected devices, a collection belt is formed at about .3 ~ 10em. The outer side of the terminal of the diagonal conveyor belt and the peripheral edge of the medium-sized one that rotates in the direction of the other side of the diagonal conveyor belt are equally divided into a number of f-film loading devices, which are a horizontal = crochet gripping device. “Yes” where the direction of rotation of the belt is equal to the starting end, which extends into the aqueduct and extends above the plastic film conveyor belt. Most rows can extend into the water stream. 1230099 V. Description of the invention (8 ) " ------ Set forward conveying; η &: ^ When the garbage is mixed with water and poured into the forward rotating screen device, it will be very special. Since the screen is In the 5 square centimeter .. Tian plastic film is laid on the net, there will be a lot of water droplets on the plastic "Shi", so that the plastic film is trapped in the screen hole of the screen device, forming a very m: Press this film tightly on the screen. When the screen is transported forward, the screen device will blow upwards. The function is to blow the light material off the screen and drop it to the collection belt in front. 'At this time, because the small water bag produced on the plastic film has considerable weight, the plastic T 2 film will not It can still be conveyed to the front of the screen by blowing, that is, the downward turning position of the screen device. At this time, the items on the screen device are left with the plastic film closely attached to the screen device, and For heavy and large materials, when the screen device starts to turn downwards, a volume and a harder item will be picked up by a fast turning wheel to collect all the materials over 5cra on the collection belt in front; The key is that the gap between the screen device and the dial is only 5 cm. Because the speed of the screen device will cause a forward impulse, almost only substances less than 1 cm to 2 cm can escape the fate of being picked out. The plastic film itself has great adhesion in the presence of water, and the water bag recessed on the surface of the plastic film will also be closely attached to the screen device. Each plastic film only obediently follows the screen. The screen device will be separated from the screen device by turning below 90 degrees. Since the plastic film itself is very thin ^ will never exceed 0.5 cm, so it can be collected very cleanly. When it is covered with some bulky substances, it can also be closed immediately.
