Problems solved by technology

[0003] At present, there are some reduction and recycling technologies and equipment used in the field of domestic waste, but the existing equipment has a low degree of automation, high cost of bacterial agent auxiliary materials, large floor area, complicated supporting facilities, and secondary pollution (exhaust gas, waste water) ) serious, poor sanitation conditions, etc., cannot adapt to the shortage of land resources and the characteristics of urban waste, which seriously limits the resource utilization of organic perishable components in urban domestic waste and the source reduction of domestic waste
In addition, most of the existing waste reduction and recycling integrated equipment adopts the composting method. Part of the composting products in the composting process are directly used as recycled materials, and the other part is used as flower substrates, organic fertilizers, etc.
After research by the applicant, it was found that although the returned compost products can inoculate the fresh materials with microorganisms, this method contains a large amount of decomposed materials, so its porosity is small and the microbial content is low, so it can be mixed with fresh materials Afterwards, it will not only cause insufficient amount of inoculated microorganisms, but also destroy the aerobic fermentation environment in the material

Embodiment 1

[0035] Such as figure 1 with 2 As shown in the figure, an underground integrated device for reducing domestic waste and resources, the main body of the device is located below the ground, and the structure for accommodating the main body of the device can be excavated in advance. The main body of the device includes a crusher, a fermentation cylinder, a vibrating screen and a feeding device, which are erected on a steel frame as a whole. There are hydraulic lifting rods on the four corners of the frame, and the bottom of the hydraulic lifting rods is supported by the main body of the accommodating device. On the bottom of the underground structure, it is used to lift the main body of the device out of the ground. In this example, the fermenting cylinder adopts the layered fermentation reactor provided in the invention patent with the application number 201510981168.X, that is, the reactor includes a cylinder and a stirring device, and the stirring device includes: a central s...

Embodiment 2

[0053] Compared with Example 1, the difference of this example is that the top of the fermentation cylinder body is round, and no condensed water collection device is provided, such as Image 6 shown. The condensed water volatilized and condensed during the fermentation process is still returned to the fermentation material.

[0054] The integrated devices of the above three embodiments can all be used to ferment domestic waste without adding microbial agents and related conditioning agents. Below, the present invention combines the effect data of several experiments, so that those skilled in the art can more clearly understand the effects of the various improvements of the present invention.

[0055] test 1

[0056] This test adopts the integrated device of embodiment 1, specifically carries out according to the following steps:

[0057] 1) Pour the sorted kitchen waste into the trash can one after another, take out the alarmed non-organic waste from the side, record the w...

Abstract

The invention discloses an underground household garbage reduction resource integrated device and a treatment method thereof, and belongs to the field of environment-friendly equipment. The device is integrally located below the ground. A garbage can connected with a pulverizing device is arranged above the ground. The bottom of the can is capable of being opened downwards so that garbage can enter the position below the ground, and subsequent resourceful treatment is finished. Falling garbage is pulverized through the pulverizing device located under the garbage can and then falls into a cascading high-temperature fermentation barrel; a feeding port of the cascading high-temperature fermentation barrel is the position of the above pulverizing device, and a discharging port of the cascading high-temperature fermentation barrel is located in the other end of the barrel and connected with a vibration screen. An oversize product outlet of the vibration screen is connected with an automatic material returning system, the system is internally provided with a plastic blowing and disengaging device. The device is provided with an elevating device. The underground household garbage reduction resource integrated device and the treatment method thereof are suitable for in-situ reduction resourceful utilization of community household garbage, environment is sanitary, and secondary pollution is avoided; and based on PLC module deep control, the automation and intelligence degree is high; and the structure in the device is compact, the civil engineering cost is saved, dismounting and mounting are convenient, and maintenance is easy.

Description

technical field [0001] The invention belongs to the field of environmental protection equipment, and in particular relates to a buried domestic waste reduction and resource integration device and a processing method thereof. Background technique [0002] With the advancement of my country's urbanization, the proportion of urban population is increasing rapidly. In 2015, the national urban permanent population was 771.16 million, accounting for 56.10% of the total population, an increase of 1.33 percentage points over the previous year. At the same time, with the improvement of the living material level, the total waste output has increased significantly. In 2015, the total output of domestic waste in my country reached 192 million tons. The contradiction between the increasing amount of waste and the terminal treatment facilities with insufficient capacity is highlighted. . For this reason, the "Thirteenth Five-Year" National Urban Household Waste Harmless Treatment Facilit...
