Novel fermenting bed device and fertilizer fermenting method

Abstract

The invention discloses a novel fermenting bed device. The upper part of a fermenting pool is in an opening shape; a storage pool is located at the side part of the fermenting pool; through grooves intransverse penetrating are formed in the lower side part of the fermenting pool; the fermenting pool is communicated with the storage pool through the through grooves; guide rails are respectively arranged at the top parts of two side walls of the fermenting pool; walking motors are fixedly arranged on a rack; the walking motors are in transmission connection with walking wheels. A fermenting method of the novel fermenting bed device comprises the following steps: a, addition of excrement and urine; b, addition of substrate packing; c, addition of accessories. The novel fermenting bed devicedisclosed by the invention has the advantages that a technological process is optimized, power consumption and equipment cost are effectively reduced, a very energy-saving effect is obtained, regulardredging work in the later period becomes very convenient, a field operation environment is obviously improved, and the novel fermenting bed device is very environment-friendly and is very beneficialfor proceeding of fermentation.

Description

Technical field [0001] The invention relates to the technical field of fermentation beds and fertilizer fermentation methods, and more specifically to the technical field of heterotopic fermentation beds and fertilizer fermentation methods. Background technique [0002] At present, the common aerobic fermentation bed for ectopic manure and urine is mainly composed of a secondary storage ditch and a fermentation tank. The method for composting and fermentation of manure and urine using this fermentation bed is to pass the livestock and poultry manure through a primary pump It is sucked from the septic tank to the secondary storage ditch, and then transported by the secondary pump to the fermentation tank to mix with solid dry matter such as grain bran or plant straw dry powder for fermentation. However, the use of this ex-situ fermentation bed and fermentation method has the following shortcomings: one is that the two-stage pump consumes a lot of electric energy, which increases t...

AI Technical Summary

Problems solved by technology

However, the use of this ectopic fermentation bed and fermentation method has the following disadvantages: First, the two-stage pump consumes a lot of power, which increases the cost of fermentation. Unfavorable, not very environmentally friendly, and the working environment of workers is harsh; second, the mixing time of feces and urine with solid dry matter is long, which is not conducive to the turning of fermented materials, which reduces the fermentation efficiency and has a certain impact on the fermentation effect; The demand for materials is large, especially in areas where resources such as rice bran and plant straw dry powder are scarce in the surrounding areas. The problem of purchasing and supplying solid dry matter filling auxiliary materials for manure treatment by this method is particularly prominent; It belongs to semi-static composting fermentation. Most of the time, the materials in the fermentation tank are in a static state. In a static state, the water in the surface material evaporates slowly, which is not conducive to the fermentation. Fifth, the raw materials in the current common fermentation process are mostly crops Straw, its nutrient composition is relatively simple, and the order and timing of adding fermented raw materials have not been accurately and reasonably controlled, resulting in insufficient fermentation of raw materials and poor nutrient composition of fermented fertilizers

[0003] In addition, when the material in the fermentation tank is being fermented, it is necessary to use a compost turning machine to periodically turn the material. However, the compost turning machines commonly used in the market currently have the following disadvantages: First, the compost turning machine does not have The function of spraying the fermentation bacteria liquid is currently sprayed by manual use of nozzles. However, this method is not only time-consuming and labor-intensive, but also increases labor costs, and the bacteria liquid falls on the surface of the turning material, which cannot be fully mixed with Turning the material for contact mixing must rely on the turning machine to carry out the turning and stirring to mix with the material, so the mixing effect of the bacteria liquid and the material is greatly reduced, which is not conducive to the fermentation; the second is the degree of fermentation of the material during the fermentation process It is not easy to judge, and it is usually judged manually by experience, but in this way, the judgment is not accurate enough, and the degree of fermentation of the material cannot be accurately judged; the third is that the compost turning effect of the common compost turning machine is not very ideal, and some of them are hardened. The material cannot be crushed, resulting in insufficient compost turning. Although some compost turning machines are more fully compost-turning, their turning efficiency is low; Fourth, a certain amount of air needs to be regularly introduced into the fermented material during the fermentation process. to meet the oxygen required for the fermentation of microbial strains, and the current common method of supplementing oxygen is to use a compost turner to increase the contact area between the fermented material and the air. However, in this way, the air and material The contact area is small and cannot well meet the oxygen required for microbial fermentation
