Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a livestock manure processing device that ferments livestock manure and urine from, for example, a pigsty in a compost house and converts them into high-quality compost.

(Prior Art) The applicant previously manufactured a livestock manure processing apparatus as shown in FIG. That is, the inside of the fermentation tank 1 is partitioned with a partition net 2, a large number of ventilation holes 1a are formed on both side walls, the upper lid 3 is opened, a certain amount of livestock feces is thrown into the inside by a screw conveyor 4, and a certain amount of urine is dispersed. and close the top lid 3. Ventilation hole 1a on both side walls for outside air
The excrement deposited inside through the partition screen 2 is fermented, heated to 60°C to 75°C over a day and night, and converted into compost.

Furthermore, as shown in Japanese Utility Model Application Publication No. 52-79381, a continuous composting device with high feces is known, which has a large number of small-diameter nozzle holes and has blow pipes with both ends open to the outside arranged horizontally in a stepped manner. be.

Furthermore, as shown in Japanese Utility Model Publication No. 51-29090, an air chamber is provided at the bottom of the bottom plate of the main body of the fermenter, which has a side wall and a bottom plate and accommodates livestock manure, and the bottom plate has a through hole that communicates with the air chamber. A ventilation pipe with a large number of ventilation holes on the outer periphery is installed in the tank main body and communicates with the air chamber, and a blower device that communicates with the air outside the tank is connected to the air chamber. Manure fermenters are also known.

In addition, as shown in Japanese Patent Application Laid-Open No. 54-54876, an air supply pipe having a large number of air discharge holes and an exhaust pipe having a large number of air introduction holes are installed vertically, and the lower end of the air supply pipe is connected to the bottom wall. Composting and fermenting devices for municipal waste, etc., which are opened at the bottom are also known.

However, there is a problem in that it is difficult to uniformly allow outside air to flow throughout the animal manure, and it is not possible to obtain sufficiently fermented, high-quality compost.

(Objective) The object of the present invention is to effectively ferment animal manure and urine in a compost house to obtain high-quality compost at a low cost.

(Structure) In order to achieve the above object, the present invention has a large number of horizontal pipes each having mesh-shaped small holes arranged in two parallel rows at regular intervals from both sides toward the center on the compost house floor. One end of the pipe is connected to the outside air, and vertical pipes with mesh-like small holes formed in each horizontal pipe are vertically protruded and fixed at regular intervals. Exhaust holes are formed in appropriate places on the outside wall of the compost house, and livestock manure and urine are removed from the compost house. The invention is characterized in that it is equipped with means for supplying.

Hereinafter, a detailed explanation will be given based on an example. 10
In a compost house, a horizontal pipe 11 of 3.5m x 100φ with a mesh-shaped small hole 11a formed on the floor is connected to a three-way joint 20.
The horizontal pipes 11 fitted on both sides are arranged in two parallel rows at regular intervals from both sides toward the center on the floor of the compost house, and placed on the floor with support plates fixed perpendicular to the bottom surface of the three-way joint. Then, one end 11b is exposed outside the compost house 10 to communicate with the outside air, and four 80cm x 70φ capped vertical pipes 12 with mesh-shaped small holes 12a formed above the three-way joint 20 are placed vertically at regular intervals. It protrudes and holds the vertical pipe 12 vertically. 13 is the top lid of the compost house, and 14 is the door.

When in use, open the door 14 of the compost house 10 and open the pig house 15.
The livestock manure 17 in the primary fermentation tank 16, which stores the livestock manure, is put into the compost house 10 until the top of the vertical pipe 12 is covered, the door 14 is closed, and the upper lid 13 is opened to store the urine from the pigpen 15. The urine in the storage tank 18 is dispersed from the upper opening by the pump, and the upper lid is closed.

The primary fermented animal manure in the compost house retains urine water,
The high-temperature fermentation is further continued by the ventilation uniformly blown out from the mesh-shaped small holes 11a and 12a of each of the horizontal pipes 11 and vertical pipes 12, and the compost is quickly converted into good compost.

(Effects) The present invention has a large number of horizontal pipes with mesh-shaped small holes arranged in two parallel rows from both sides toward the center from both sides toward the center, with one end communicating with the outside air. , Vertical pipes with mesh-shaped small holes formed in each horizontal pipe are vertically protruded and fixed at regular intervals, and exhaust holes are formed at appropriate locations on the outside wall of the compost house, thereby providing a means for supplying livestock manure and urine to the compost house. As a result, the livestock manure accumulated in the compost house is blown out evenly over the entire floor surface through the mesh-shaped small holes of the horizontal pipes arranged in two rows parallel to the floor surface, and the air is blown out evenly over the entire floor surface through the mesh-shaped holes of the horizontal pipes arranged in two rows in parallel on the floor surface. Due to the uniform airflow from the small holes and the water-retaining effect of urine, the entire animal manure in the compost house is fermented uniformly at high temperatures, producing good compost. Therefore, livestock manure and urine in the livestock barn can be fully utilized.
