Problems solved by technology

[0002] At present, the country and governments at all levels have listed the comprehensive treatment of urban domestic waste as a key project for sustainable social development, but the technology of urban waste treatment lags behind.
Chinese patent application 200910074832.7 for the treatment method of domestic waste. Due to the large amount of water mixed in the garbage collection process, it is easy to accumulate water and ferment to breed mosquitoes and flies during the storage and transportation of urban domestic waste, causing initial pollution, and many times in the subsequent production and transportation process. Turning over and entering the landfill and waste treatment plant, the production cycle is three to ten days, which makes the pollution continue to worsen and deepen, and the energy consumption is increased due to the high moisture content of the waste in the process of processing

Embodiment 1

[0024] figure 1 Shown, the process flow diagram of the present invention.

[0025] (1) Use a garbage drop box with a sieve hole at the bottom to collect raw garbage;

[0026] (2) The full garbage drop box is transported to the special lifting equipment at the primary selection machine by a special garbage removal vehicle;

[0027] (3) The special lifting equipment directly dumps the garbage in the garbage drop box to the inlet of the primary separator;

[0028] (4) The garbage is pre-sorted by the primary separator, and the pre-sorted garbage of large bricks and long organic matter with a particle size greater than 300mm is sorted out;

[0029] (4) The crushed chunks of masonry are used as raw materials for making bricks;

[0030] (5) The long organic matter is crushed into materials with a particle size of no more than 100mm. After magnetic separation, it is mixed with pre-sorted garbage, and sent to a 20-25mm drum sieve for sieving. Brick raw materials, the screened mate...

Embodiment 2

[0036] figure 1 As shown in the figure, the raw garbage is selected by the primary separator to select materials with a particle size greater than 300 mm, and the inorganic materials are sterilized and pulverized to make bricks. The organic matter is sheared and crushed until the particle size is not greater than 100 mm, and then returns to the conveyor belt with a permanent magnetic drum, and the selected materials with a particle size of less than 300 mm are screened together with the drum sieve. The sieve hole diameter of the drum screen is 20 mm. , the material with a particle size of less than 20 mm is sent to the undersize belt of the drum sieve and sent out to be composted. The scrap iron sorted out by the permanent magnet drum is sent to the recycling station. The sieve with a particle size of 20mm or more and 300mm or less enters the centrifugal dehydrator for dehydration, so that the moisture content of the material is less than 5%, and basically maintains the origi...

Embodiment 3

[0038] figure 2 and image 3 As shown in the garbage drop box, the bottom of the box is a cone, and the bottom of the cone is provided with a sieve to facilitate water control.

[0039] The garbage drop box also includes a base on which the garbage drop box is placed. The edge of the base has a slope to the center, the center is lower than the edge, and the center is provided with a water outlet. Adjacent city sewer or resident septic connection.

Abstract

The invention relates to treating method and device for urban domestic rubbish, belonging to the technical field of environmental protection. The treating method for urban domestic rubbish comprises the following steps of: (1) collecting rubbish by a rubbish throwing box which is provided with sieve holes; (2) delivering the rubbish throwing box to an initial selection machine; (3) dumping the rubbish in the rubbish throwing box to the initial selection machine; (4) sorting the rubbish by the initial selection machine in advance for sorting out large bricks and large and long organic matters; (5) crushing the large and long organic matters; carrying out magnetic selection and screening; using the screen underflow for compost or as a brick manufacturing raw material; carrying out wind selection on the screen overflow after drying; and (6) obtaining different matters by wind selection to be respectively used according to different types. The rubbish throwing box in the treating method of the domestic rubbish comprises a box cover and a box body, wherein the lower part of the box body is provided with the sieve holes. The invention decreases the content of water in the rubbish, reduces stirring, shortens production period, and reduces environmental pollution and energy consumption in the process of treating the rubbish.
