The transmission of the first drum screen: the screen drum motor 11 → the screen drum rotating riding wheel 6 → the screen drum 1 rotates.

A central shaft 2 is arranged in a screen drum 1 of the first rotary screen along the length direction, and convex bundling belts 3 are arranged on the central shaft 2 along the length direction and the circumferential direction at intervals. The belt 3 rotates with the central shaft 2. The belt bundle belt-drawing mechanism in the screen drum is additionally arranged for the application. The bundling and pulling belt 3 is processed into a strip shape by adopting a waste conveying belt, for example, the width is five centimeters, and the length is smaller than the radius of the screen cylinder 1 (the inner surface of the screen cylinder 1 is not touched during rotation). The bundling and drawing belt 3 has the functions of: firstly, the garbage is whipped in the rotation process, so that a powerful stirring effect is achieved, and the garbage attached to the large and fast garbage is whipped off, so that the large garbage is cleaner, and the sorting of a subsequent platform is facilitated; secondly, the garbage with large water content and formed into rolling balls is broken, and screening is facilitated; thirdly, the garbage tightly stuck and blocked on the sieve pores is cleaned, and the screening is also facilitated. An outlet at the tail end of the first drum screen (garbage which does not leak more than 8 cm) receives a conveying belt, and then receives an air separation falling object conveying belt and a heavy material conveying belt (receives the heavy material conveying belt and receives a material selecting platform); the lower part of the screen cylinder of the first rotary screen is connected with the conveying belt. The belt bundling and pulling mechanism rotates: the belt-pulling motor 12 → the center shaft 2 → the belt 3 rotates.

Referring to fig. 3, the part names are as follows: the device comprises a box body 4, a hammer mechanism 5 (a plurality of hammer bodies are arranged on a rotating shaft, and not shown in the figure), a fine crushing machine conveyer belt 8 (at the inner side of a frame), and a fine crushing machine motor 9.

And (4) finely breaking the machine. Or a hammer-mill pulverizer and a double-shaft sieve-free crusher (the crusher directly falls on a lower conveyer belt) are conventional equipment. The fine crusher is provided with a pair roller hammer mechanism along the upper and lower parts of the box body. The garbage with the size of less than 8 centimeters screened by the first rotary screen is sent to a hopper of a fine crusher box body 4, the garbage is beaten into garbage with the size of about 3 centimeters by two groups of hammer bodies in the fine crusher box body 4, the garbage is powdered and sent to a second rotary screen (the structure of the second rotary screen is the same as that of the first rotary screen above) by a fine crusher conveyor belt, and the garbage with the size of more than 3 centimeters and the garbage with the size of less than 3 centimeters can be separated by a screen hole on the surface of a second rotary screen cylinder with the size of 3 centimeters. And (3) conveying the garbage with the size of more than 3 cm into an incinerator after being output from one end of the roller, and conveying the garbage with the size of less than 3 cm onto a conveying belt below the first roller screen for storage to serve as biological fertilizer. The fine crusher mainly comprises a machine base, a machine body, a hammer mechanism 5 (two groups, namely an upper group and a lower group, the crushes then directly fall on a lower conveyer belt), a feeding port, a hammer motor, an inspection port, a conveyer belt and a shield. Two sets of hammer mechanisms 5 are arranged along the upper and lower parts of the box body 4. The external dimension is as follows: 2.3m long, 1.2m wide and 2.8m high. Conveying a belt: the length is 6m and the width is 0.6m.

The flue gas pipeline of the incinerator is connected with the drying equipment, and the waste heat of the incinerator is utilized. Is conventional equipment. The drying equipment is connected with the flue gas dust removal equipment. The garbage after incineration can enter the farmland after magnetic separation.

The process flow comprises the following steps: the forklift conveys the household garbage into a feeding machine (large objects are manually selected) → a conveying belt → a bag breaking machine → the conveying belt → a first drum screen (separates garbage below 8 cm and above) → the conveying belt (receives garbage below 8 cm) → a fine breaking machine (crushes into garbage of about 3 cm) → the conveying belt → a second drum screen (garbage below 3 cm is used as an organic fertilizer raw material and is conveyed to a storage bin (composting yard), and small light garbage above 3 cm is conveyed to a next equipment incinerator) → the conveying belt → the incinerator (receives garbage above 3 cm) → flue gas → a material dryer (garbage drying equipment) → dust removal equipment → flue gas reaches the emission standard and is discharged into the atmosphere.

The method comprises the following steps of sorting garbage by a first drum screen (separating garbage of more than 8 centimeters), namely, separating a conveying belt → winnowing, conveying the conveying belt for one way (receiving light materials and useless incineration), conveying the conveying belt for the other way (receiving heavy materials), namely, conveying the heavy materials and the garbage for the other way to a platform for selection (receiving the heavy materials and the useful residues, such as pop cans, iron and the like, conveying a fine crusher and useless incineration).

The working principle is that the household garbage enters a garbage disposal plant, large materials (tires, glass products, quilts and the like) are manually selected, loaded into a feeding machine by a forklift, slowly fed into a conveying belt below the feeding machine, fed into a bag breaking machine by the conveying belt of the feeding machine, crushed, fed into a first drum screen by the conveying belt, and separated into garbage with the size of less than 8 centimeters and above. And feeding the garbage with the diameter of less than 8 centimeters into a fine crusher to be crushed. And light and heavy materials (residual fruits, vegetables, broken stone tiles and the like), small and large materials (plastic products, paper products, wood substances, chemical fiber products and the like) and light materials are selected from the other path of garbage with the length of more than 8 centimeters for standby. The heavy material is fed into a fine crusher through a conveyer belt to be crushed. The garbage below 8 cm is sent to a fine crusher to be crushed and then fed into a second drum screen by a conveyer belt to be separated, the material used as organic fertilizer is conveyed to a composting plant, small combustible light materials are selected out and enter an incinerator by the conveyer belt to be subjected to harmless treatment, and the generated flue gas is treated by a water dust removal device and then is discharged into the atmosphere. The metal substances are separated from the ash through magnetic separation, and the residual ash is used for processing organic fertilizer and returning to agriculture. The large plastic is separated from the light and heavy objects, and the paper products and the like are regenerated into resources for secondary utilization, so that the whole process of harmless treatment of the garbage is free from secondary pollution, the secondary utilization of the resources is realized, finally, the domestic garbage is reduced, harmless and resource treatment is realized, and the pollution caused by the domestic garbage to the environment is greatly reduced. The purpose of comprehensively treating the environment is achieved.

The above description is only exemplary of the present invention, and the various illustrations do not limit the essence of the present invention.
