Description

[Detailed description of the invention] This invention provides a porous floor with a rigid structure in a livestock and poultry house, and uses a filter material on the porous floor to separate feces onto the floor and urine below the floor and carry them out for use or purification. This invention relates to a livestock barn structure that facilitates processing.

Returning livestock and poultry manure to the land as fertilizer not only helps maintain and improve soil fertility, but also saves on expensive chemical fertilizers. However, it is generally well known that applying too much manure reduces soil properties, as well as crop properties and yields. Currently, the scale of livestock farming is expanding more and more, and the amount of manure from home-raised livestock has become too large to be input into the small amount of farmland. It is necessary to make fertilizer that is easy to use, or to purify the manure to a water quality standard that allows it to be discharged into rivers.

The form of fertilizer that is easy for cultivators to use is solid, and it is the manure that contains most of the pollutants. Therefore, the first requirement for processing and utilizing manure is to separate it into feces containing as little urine as possible and urine containing as little feces as possible.

Various methods have been used to separate manure and urine. For example, barn cleaners, which are often used in dairy cow sheds, were originally created for the purpose of separating manure and transporting it. The separation hole is clogged and the separation is incomplete, and the urine and manure are mixed together and transported outside the livestock barn.Also, the urine separation hole in the winding belt of the pig pen does not function as intended, and the manure is transported out without being separated. All of them are used in an incomplete state. Additionally, excrement separators are used to separate the mixed excreta and excrement that is carried out, but this can also be said to be incomplete as about 50% of the solids remain in the liquid mixture.

On the other hand, in livestock barns that are widely used for transporting beef cattle, etc., a large amount of bedding (sawdust, rice husks, etc.) is spread on the concrete floor, manure is mixed with this, and the material is periodically transported using a bucket troder, etc. The animals are then cleaned, placed with new bedding, and reared. In this method, all the manure is mixed with bedding and used as compost, so no sewage is discharged, and there is no pollution problem.Although it is an advantageous method, it has become difficult to obtain bedding recently, and there is no need to use enough bedding. Since this cannot be used, there is a strong desire for a method to save on this.

Therefore, in order to satisfy the above-mentioned desire to save on bedding and to completely separate manure and urine, the present invention has been developed by making the floor of the livestock barn a porous floor made of perforated plates, non-corrosive netting, water-permeable plates, etc., and adding a filtration material to the floor. Livestock are fed on top of this, and the excreted excrement falls onto the filtering material, and the urine falls through the filtering material into the filtered urine sewage chamber at the bottom, leading to the urination ditch installed on one side of the livestock barn. By completely separating the excreted excrement and excrement using a filter material, water is sufficiently removed from the solid feces left on the porous bed, and solids in the liquid that has passed through the porous bed are removed. The content should be kept extremely low.

In this way, a small amount of filtration material (bedding material) can withstand long-term continuous use, and not only can the amount of bedding material be saved, but also the excrement and urine can be almost completely separated. Feces with low moisture content are always dripping onto the porous floor and urine wastewater with extremely low solid content is dripping into the filtered urine wastewater chamber, which can be led to the urination ditch on one side of the barn. Note that the solid content left on the porous bed may be removed manually or mechanically as needed, and then a small amount of bedding material may be spread. If the filter material in the water flow basin becomes clogged and filtration becomes poor, it is easy to remove it and replace the filter material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The livestock barn structure according to the present invention will be described below with reference to preferred embodiments shown in the accompanying drawings.

FIG. 1 shows an example of the porous bed according to this invention. 3 is a perforated plate, 4 is a non-corrosive mesh, 5 is
is a water-flowing board (grating, expanded metal, etc.) made of thick steel material in a lattice pattern over the entire surface, and these are laid one after another from the bottom to the top to form a perforated floor. The filter material is filled from the top. The filtering material is preferably an inorganic or organic material with excellent filtration effect, such as sand, sawdust, or rice husk, which can be mixed with excrement and used as fertilizer.

FIG. 2 shows an example of a livestock pen structure. Supports 1 and 1' support the porous floor, and are usually constructed of concrete or the like. The porous bed is laid on this support, and livestock are raised on the filter medium 7. The lower part of the porous bed 2 is a filtered urine sewage chamber 11, where the urine filtered by the filter material 7 and the porous bed drips, and the urine sewage collected on the floor is drained through gaps provided at appropriate intervals or Drain hole 13
from there to the urinary groove 12. On the other hand, the feces mixed with the filter material on the porous bed are left in a state in which water has been removed. In addition, 8 indicates the entire livestock barn, 9,
Reference numeral 9' denotes a fence installed in the livestock barn, and the installation location of 9' and the support body 1 can be changed depending on the size of the livestock barn. In addition, the porous bed allows the filter material to be replaced at any time when it becomes clogged.
It is constructed so that it can be easily removed from and attached to the support.

Another embodiment is shown in FIG. In this embodiment, the filtered urine/sewage chamber 11 is constituted by a wall 10 surrounding it and constructed airtight. Reference numeral 13' denotes a hole into which a pipe 14 is inserted, and this pipe 14 is arranged so as to reach deeper than the water level of the urinary drainage ditch.In addition, an intake pipe 15 is provided on one side of the filtered urine wastewater chamber 11. This is connected to the exhaust fan 16. All other parts indicated by 1' and 2 to 9, 9' are constructed in the same manner as described in FIG.

In the configuration shown in FIG. 3, air is sucked from the upper porous bed by the exhaust fan 16, and urine is filtered from the excrement excreted onto the filtering material 7, and the filtering material 7 is maintained in an aerobic condition. The mixture of feces and filter material 7 is removed mechanically as appropriate, while the urine wastewater dripping from the porous bed is led from the filtered urine wastewater chamber 11 through the pipe 14 to the urination groove 12. It will be destroyed.

FIG. 4 shows a structure in which the floor of the filtered urine sewage chamber 11 shown in FIG. 3 is constructed by depositing gravel 17. In this embodiment, the urine sewage dripping from the upper porous bed comes into contact with the surface of the accumulated gravel 17 and is decomposed by the microorganisms that have grown there, so that the amount of contaminants is reduced. The urine wastewater is then discharged from 13' through the pipe 14 into the urinary drainage ditch.

FIGS. 5 and 6 show other embodiments.
That is, FIG. 5 shows a system in which an air diffuser pipe 18 is provided in the urinary groove 12, and a large number of air bubbles 21 are ejected into the urine wastewater from the air diffuser hole 19 by a pump 20, thereby supplying oxygen to microorganisms in the wastewater and purifying the wastewater. and the sixth
The method shown in the figure also involves attaching a large number of disks 23 to a shaft 24 in the urinary groove 12, and slowly rotating the disks to bring the disks 23 into contact with sewage and air. The purpose is to purify wastewater using microorganisms. 25 is a pulley. In addition, 22 is the surface of the waste water, and this surface is kept below the rotation axis, and the disk 23
As it rotates, it alternately comes into contact with waste water and the air above. In this way, feces and urine are separated on the floor of the barn where livestock are raised, and the urine wastewater is directly led to the urination groove 12 or the filtered urine wastewater chamber 11
The sewage that has been purified in the urination ditch 1
This method can be expected to have the effect of making it possible to sufficiently purify and send to the urine reservoir what was conventionally led from the livestock barn to the urine reservoir without being purified.
