Description

Fertilizer production system using excretion

The present invention relates to a fertilizer manufacturing apparatus using livestock meal, and more specifically, to enable primary fermentation and secondary fermentation of livestock meal mixed with auxiliary materials, wherein the primary fermentation process requires stirring of livestock meal and auxiliary materials. It is to be done efficiently so that the initial fermentation can be promoted, and the secondary fermentation process relates to a technology that can manufacture high-quality fertilizers by precisely measuring the moisture content and adjusting the moisture content to be optimized for fermentation.

In general, livestock manure [畜糞] and human manure [human manure] correspond to organic wastes that are often discharged, and these livestock manure are the main culprits causing not only soil and water pollution but also air pollution due to odors. As an appropriate solution to this contamination problem, a method of using livestock and human waste as fertilizer by fermenting it to be used as nutrients for crops has been proposed.

In particular, in the case of human part, since most of the constituents are water, in order to fertilize it, an auxiliary material or a moisture control agent is added to greatly lower the moisture content, and after the fermentation process, the moisture content is further lowered through the drying process. In this process, most of the moisture in the drying process was evaporated or discarded, and the moisture contained in the human waste was not utilized properly.

And, in the conventional fermentation process, stirring and fermentation are performed simply by a stirring device rotating slowly in the fermenter, but the larger the size of the fermenter, the more difficult the mixing. That is, as the heavy solid material sinks down, the upper and lower layers are not smoothly mixed, and each layer is separated. In this process, there was a problem that the fermentation efficiency was lowered because the agitation of the livestock meal and subsidiary materials was not performed properly.

And in the fertilizer manufacturing apparatus using livestock manure, the process that determines the quality of fertilizer is in the fermentation process, and the most important factors in the fermentation process are environmental conditions such as temperature and the moisture content of livestock manure where fermentation takes place.

Of course, auxiliary materials are added for moisture control, but since moisture control is performed through an approximate input amount, it was not possible to measure the moisture content of livestock meal being fermented in the fermenter in real time.

Since the commonly used soil moisture sensor can only be used for objects with little moisture content, in the case of a fermenter with a high moisture content, the existing moisture sensor could not be applied.

The separation method can be separated into an upper layer and a lower layer by using precipitation, or can be separated through a structure such as a mesh through which only moisture can pass.

Even if moisture has been removed to some extent through the livestock serving supply unit 100 , most of the human part is water, so it must be mixed with auxiliary materials for moisture control and fermentation in the primary fermenter 300 .

The liquid manure raw material separated from the livestock manure supply unit 100 is sent to the liquid manure storage tank 200, and is fermented as liquid manure and stored. The liquid fertilizer storage tank 200 is used as liquid fertilizer as it is, or sent to the secondary fermenter 400 to control moisture.

The supply/discharge part 320 is rotated to come to the lower part through the , and then the first on/off valve 321 is opened so that the discharge is made.

The supply/discharge unit 320 of the primary fermenter 300 is configured such that supply and discharge are performed in one place. That is, it is also used for supply when inputting livestock parts and auxiliary materials into the first body part 310, and is used when discharging the mixture in which the primary fermentation has been completed. The reason this operation is possible is that it can be opened and closed by the rotation operation unit 340 capable of rotating the first body unit 310 and the first opening/closing valve 321 installed in the supply/discharge unit 320 .

And the first stirring member 330 is installed vertically in the center of the first body portion 310, the first stirring shaft 331 installed in the form of penetrating the top and bottom of the first body portion 310 and , a plurality of first stirring blades 332 formed entirely on the first stirring shaft 331, and a first stirring motor 333 installed at one end of the first stirring shaft 331 to generate a rotational force ); consists of

When explaining the fermentation process of the primary fermenter 300, as shown in FIG. 3, the first body part 310 is positioned so that the supply/discharge part 320 is on the upper part, and then the first on-off valve 321 is opened. In an open state, the shaft portion and auxiliary materials are put through the supply/discharge unit 320 . Then, with the first on/off valve 321 closed, the first stirring member 330 is operated so that the shaft portion and the subsidiary materials can be mixed. In the mixing process, the rotation operation unit 340 is operated to rotate the first body unit 310 as shown in FIGS. 4 to 5 . By continuously rotating the first body part 310 through the rotation operation part 340 while operating the first stirring member 330, the first body part 310 repeatedly performs an inverted state of the upper part and the lower part. will lose

Specifically, as shown in FIG. 8, the water level sensor 440 and the torque sensor 450. It further includes a moisture content calculation unit 460 for calculating the moisture content as a measured value of so that the liquid fertilizer is supplied through the liquid fertilizer supply unit 430 when the moisture content is insufficient.

When the moisture content of the mixture input to the secondary fermenter 400 is low, the rotational load on the second stirring shaft 422 of the second stirring member 420 is increased. Accordingly, the moisture content can be calculated using the measured value of the torque sensor 450 for measuring the rotational load of the second stirring shaft 422, and the average measurement of the torque sensor 450 for a predetermined time to minimize the error. It is desirable to allow the operation to be performed with a value. And since the water level sensor 440 is a factor that affects the torque of the second stirring shaft 422 , the measured value of the torque sensor 450 is proportional to the water level.

That is, the moisture content calculation unit 460 determines that the moisture content is insufficient when the torque value measured through the torque sensor 450 exceeds the threshold value based on a threshold value set differently for each water level, and the liquid fertilizer supply unit ( 430) to send a supply signal. Then, the liquid manure is injected from the liquid manure supply unit 430, and the torque is measured again.

In the secondary fermenter 400 of the present invention made in this way, the moisture content can be precisely measured, and by using the liquid fertilizer separated from the livestock serving supply unit 100 for moisture control, precise control is possible in a state optimized for fermentation. to have a possible advantage.

When fermentation is completed through the secondary fermenter 400 as described above, the fermented mixture is produced as a solid fertilizer through the dryer 500 and the molding machine 600 .

Although the present invention has been described above with reference to the above embodiments, it goes without saying that various modifications are possible within the scope of the technical spirit of the present invention.
