Equipment and process for rapid fermentation of biomass waste to produce organic fertilizer

Abstract

The invention discloses a device and a process for producing organic fertilizers through quick fermentation of biomass waste. The device comprises heating equipment and automatic fermentation equipment, wherein the heating equipment comprises a hot blast stove and a hot blast conveying pipeline; the automatic fermentation equipment comprises a control module used for controlling operation of the device as well as a fermentation main unit, and a feeding port and a discharge port are formed in the fermentation main unit; the fermentation main unit comprises a case, a stirring shaft and a drive mechanism, a stirring cavity is formed in the case, the stirring shaft is arranged in the stirring cavity, and the drive mechanism is used for driving the stirring shaft to rotate under control of the control module; a heat conduction cavity connected with the hot blast conveying pipeline is formed in the case; a strain feeding port is formed in the fermentation main unit. The device is assembled by combining integrated fermentation treatment equipment and residue pre-treatment equipment on the basis of agricultural waste microorganism treatment techniques, organic waste produced in bases, cities and factories can be quickly and harmlessly treated and used as fertilizers, and the device and the process are efficient and environment-friendly.

Description

Technical field [0001] The invention relates to the field of waste recycling and utilization, in particular to a treatment equipment and a treatment process for biomass waste. Background technique [0002] During the production process of the vegetable base, a large amount of vegetable leaves, vines, diseased plants, residues and weeds and other organic wastes are generated. These plant residues are often piled up by vegetable farmers in the fields, roadsides or abandoned rivers. Part of the plant residues will be burnt on the spot after natural drying, polluting the air; most of the plant residues are left to rot naturally at the edge of the ditch or in the ground. On the one hand, they become the breeding and overwintering places of vegetable diseases and insect pests, so that vegetable diseases and insect pests continue to spread and spread. , Forming a vicious circle; on the other hand, a large amount of these organic matter rots, stinks, breeds mosquitoes, flies, and pathoge...

Problems solved by technology

There are various problems in these processing methods: there are various types of biomass materials, such as juicy ones, such as tubers, melons and fruits, and vegetable leaves, which have a lot of water, are not easy to crush, and are easily corrupted and pollute the environment. Fibrous residues, such as pepper stalks, eggplant stalks, etc., are difficult to rot, making it difficult to handle; ordinary stacking retting has slow fermentation and low temperature, which makes it difficult to kill vegetable pests and diseases, which is not conducive to the continuous production of vegetable bases; due to the long processing time , resulting in a large site occupation, due to open-air treatment, once it rains, the sewage will flow around, and the second pollution will be large; without a reasonable ratio, the fertilizer efficiency is low; manual composting is labor-intensive, the effect is not ideal, and it is difficult to promote

For example, rice straws are roughly crushed during harvesting and plowed into the field on the spot, but they often have not rotted after half a year, which affects the growth of crops; although the technology of using straws to produce biochar and organic fertilizers is relatively mature, the collection radius is too large , the transportation cost is too high, the enterprise is unprofitable, and the enthusiasm of farmers to send raw materials cannot be raised
