Composting system suitable for production of agricultural microbial fertilizer

Technical Field

The invention relates to the technical field of microbial fertilizer production, in particular to a composting system suitable for agricultural microbial fertilizer production.

Background

The microbial fertilizer is a product which leads crops to obtain specific fertilizer effect due to the life activity of microorganisms, and is a fertilizer used in agricultural production. The microbial fertilizer has been developed in China for nearly 50 years, and the gradual development process of the microbial fertilizer in China is explained from the evolution of rhizobium agents, bacterial fertilizers and microbial fertilizers in names.

The microbial fertilizer contains a large amount of beneficial microorganisms, can improve the nutrient condition of crops, fix nitrogen and activate some invalid nutrient elements in soil, and creates a good soil micro-ecological environment to promote the growth of the crops. [1] There have been some misunderstandings and prejudices of the social perception of microbial fertilizers for a long time. One opinion considers that the fertilizer efficiency is very high, and the fertilizer can be used as a universal fertilizer, even the Yan can completely replace the chemical fertilizer; another rule of sight is that it is not a fertilizer at all. In fact both of these are prejudices. Years of experiments in the world prove that the symbiotic nitrogen fixation efficiency can be improved by inoculating leguminous crops such as soybeans, peanuts and the like with rhizobium, the yield increase effect is really realized, the yield increase effect is also realized on non-leguminous crops by reasonably applying other bacterial fertilizers for seed dressing or applying microbial fertilizers, and the effect which cannot be achieved by chemical fertilizers is realized.

During the production process of the microbial fertilizer, composting treatment is needed, and the purpose of composting is to enable microorganisms in nutrient substances to quickly proliferate, so that the microbial fertilizer is produced at the fastest speed;

in order to realize the process, through retrieval, the Chinese patent discloses a composting device (publication No. CN1193965C), the technical content of which mainly comprises that the top of a composting bin is provided with a feed hole, a stirring shaft and an exhaust pipe, the periphery of the composting bin is provided with double-layer side walls, and constant-temperature hot water is injected between the inner and outer two layers of side walls through the connection of a hot water inlet and outlet pipe and a constant-temperature water tank to form a constant-temperature hot water insulation layer; the side surface of the composting bin is also provided with a composting discharge hole; the bottom of the composting bin is provided with a vent pipe, a drain pipe and a buffer layer, the stirring device comprises a motor, a stirrer and a screen, the stirrer and the screen are arranged in the composting bin, and the stirring shaft is arranged in a stirring shaft hole through a bearing and connected with the motor to drive the stirrer to stir; the ventilation system comprises a fan and an air pipe, and is connected with the air pipe through the air pipe. The advantages that the hot water is heated at constant temperature, the ventilation air flow is controlled in the buffer layer and evenly permeates the compost, the stirrer can ensure that the compost feeding material is fully turned in the bin, the energy consumption is low, and the efficiency is high;

the above patent, when actually used, has the following disadvantages:

1. during composting, microorganisms can propagate in a large amount, and simultaneously, a large amount of heat energy can be generated, so in order to quickly cool a microbial fertilizer pile and make the fertilizer more uniform, the patent relates to a stirring device, but the stirring device realizes cooling and stirring treatment on the fertilizer by 2-4 multi-tooth spiral stirring rods, the fertilizer cannot be raised in the whole stirring process, the contact area with air is small, and the effects of stirring and cooling cannot reach the expected effects;

2. during composting, a large amount of aerobic microorganisms exist, so that air containing oxygen needs to be introduced into the fertilizer pile regularly, for this reason, the ventilation device is arranged in the patent and supplies air into the composting bin as single-point air, but in actual use, the volume of the composting bin is large, the single-point air supply consumes long time and has poor effect, and in addition, the ventilation device arranged in the patent only can carry normal-temperature air into the composting bin, so that the multi-point rapid cooling of the whole fertilizer pile cannot be realized;
