Drainage and aeration system suitable for large perishable garbage machine fertilizer forming equipment

Abstract

The invention discloses a drainage and aeration system suitable for large perishable garbage machine fertilizer forming equipment, which comprises a shell, a steel wire mesh protective layer, a geotechnical cloth filter layer, a gravel layer formed by stacking gravel, a steel wire mesh support layer, a permeable rock-fill layer formed by stacking block stones and a drainage blind pipe are sequentially arranged in the shell from top to bottom, a drainage groove is arranged outside the shell; the drainage blind pipe is communicated with the drainage groove; an aeration nozzle is arranged below the steel wire mesh protection layer, and aeration holes of the aeration nozzle face the steel wire mesh protection layer. According to the system, the percolate can be rapidly discharged through the bottom pervious layer jointly composed of the permeable rock-fill layer, the steel wire mesh support layer, the gravel layer, the geotechnical cloth filter layer and the steel wire mesh protective layer in combination with the drainage blind pipe, efficient aeration is achieved through the anti-blocking aeration nozzles, and finally relative separation of gas, liquid and solid phases in the composting process is achieved.

Description

technical field [0001] The invention relates to the technical field of garbage composting, in particular to a drainage and aeration system suitable for large-scale perishable garbage composting equipment. Background technique [0002] With the continuous improvement of people's living standards, the amount of domestic waste is also increasing day by day. As a highly polluting, wide-ranging and persistent pollutant, it greatly threatens people's yearning for a better environment and a happy life. [0003] In order to alleviate the huge pressure brought by the contradiction between production and location, Jiangsu, Zhejiang and Shanghai and other economically developed eastern regions took the lead in exploring a new path. Through decentralized perishable waste on-site resource treatment, the reduction of waste at the source is achieved, and the effect is good. At present, it has obtained large-scale promotion and application. In the existing decentralized perishable waste co...

Problems solved by technology

However, as an immature new technology, the bottom plate of the equipment chamber is welded by stainless steel plates for the convenience of mechanical stirring. The drainage holes at the bottom are easily blocked by pasty perishable garbage, making it difficult to drain water, which in turn affects exposure. Oxygen supply effect

Among the existing mechanical fertilization equipment, except for the equipment mainly based on the 12-48h electric heating and drying process (which needs to be eliminated), only a very small number of equipment products can meet the moisture content standard, and the maturity of the products is generally low, which is difficult to obtain. Meet landscaping and farmland application requirements

[0004] Therefore, there is an urgent need for a new process to solve the problems of difficult drainage and low aeration efficiency in the process of machine fertilization, so as to ensure that the treatment of perishable garbage will not become a restrictive factor affecting the smooth progress of garbage sorting.
