Description

[Detailed description of the invention] This invention makes the floor of a compost production facility durable so that heavy objects such as tractors and bucket loaders can run directly on the ventilation floor, and also maintains good ventilation at all times. The present invention relates to a ventilation bed in a compost production facility that can be maintained and efficiently produce fully ripened compost over a long period of time.

First, the applicant installed a fall prevention perforated plate horizontally on the floor of a compost manufacturing facility on the top surface of an aeration crushed stone layer in which a perforated ventilation pipe was surrounded by crushed stones, cobblestones, etc. A ventilation bed is formed in which sand layers are sequentially provided three-dimensionally on the top of the board, and aerobic fermentation bacteria are effectively propagated in the compostable material stored on the ventilation bed by stirring and conveying action and circulating ventilation action. We have developed a compost manufacturing facility that can produce fully ripened compost within a short period of time, and as it is put into practice, it is showing considerable results.

By the way, in the case of the above-mentioned ventilated floor, the sand layer formed at the top layer was simply laid over a certain thickness on the top surface of the perforated fall prevention plate.
The agitation of the composting material is difficult to handle, and as a result, the loading and unloading of composting materials cannot be carried out efficiently using tractors or bucket loaders that move directly on the ventilation bed. If foreign matter such as straw gets entangled in the agitator during transportation work, the sand layer is easily scraped off by the foreign matter, and it is not possible to maintain a sand layer of appropriate thickness at all times, which of course makes it impossible to equalize the ventilation effect over the entire surface. However, there were drawbacks such as clogging of the sand layer due to the scooping and pressing action of the stirrer, and there was a strong desire to improve this problem.

In view of the above, the present invention forms the floor of a compost production facility into a ventilated floor in which a perforated plate to prevent falling is laid horizontally on top of an aerated crushed stone layer with a perforated ventilation tube surrounded by crushed stones, cobblestones, etc. A thick ventilation board with many ventilation holes perforated over the entire surface is laid horizontally on the top surface of the ventilation floor, and the top surface of the ventilation board and the ventilation holes are filled with sand to make the entire ventilation floor strong. This makes it possible to carry heavy loads such as tractors and bucket loaders to carry out the work of bringing in composting materials and carrying out the work of compost efficiently, and even if foreign matter such as straw gets entangled in the mixer. In a compost production facility where the entire sand layer can be expanded and softened so as not to cause clogging, it is possible to maintain a sand layer with an appropriate amount of ventilation at all times to ensure uniform ventilation. DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to provide a ventilated floor, a preferred embodiment of the ventilation structure in a compost manufacturing facility according to the present invention will be described below with reference to the accompanying drawings.

In the drawing, 1 is a compost production facility that can turn the stored composting material A into fully ripened compost within a short period of time by aerobic fermentation bacteria generated by stirring and conveying action and smooth circulation of outside air. hand,
In this embodiment, the compost manufacturing facility 1 is formed by an oblong composting tank 2 that can accommodate a large or small volume of composting material A.

The floor of the compost manufacturing facility 1 consists of a perforated ventilation pipe 5 with a large number of ventilation holes 6 perforated on its circumferential surface, and a ventilation crushed stone layer 4 surrounded by crushed stones, cobblestones, etc. A fall prevention perforated board 8 made of a plate or the like is formed on the ventilation floor 3 laid horizontally, and a thick ventilation board 9 is provided with a large number of ventilation holes 10 over the entire surface on the upper surface of the ventilation floor 3. Lay it horizontally. The top surface of the ventilation panel 9 and the ventilation holes 9...
The inside is filled with sand 11.

The ventilation panel 9 may be made of expanded metal instead of being formed in a lattice shape as shown in Fig. 3. Either a suction type or pressure type fan is connected to the end of the perforated ventilator 5 so that outside air can circulate smoothly from top to bottom and from bottom to top within the composting facility 1.

Therefore, the ventilation floor 3 of the compost production facility 1 is
As shown in FIGS. 3 to 3, a perforated ventilation pipe 5 is surrounded by crushed stones, cobblestones, etc. 7 to form an aeration crushed stone layer 4, and a fall prevention perforated plate 8 is placed on top of the aeration crushed stone layer 4.
Moreover, on the upper surface of the ventilation floor 3, a thick ventilation panel 9 having a large number of ventilation holes 10 perforated over the entire surface is laid horizontally. ...Since the interior is filled with sand 11, the durability of the entire floor of the compost production facility 1 is significantly increased compared to conventional compost production facilities, and it is suitable for carrying in composting material A or for composting. The carrying out work can be carried out efficiently using a working machine such as a tractor or bucket loader that moves on the ventilation floor 3 of the compost manufacturing facility 1, and at the same time, it is possible to prevent foreign matter such as straw from entering the mixer during stirring and transporting the composting material A. Even if a situation occurs in which the sand layer is forcibly removed due to entanglement, the presence of the ventilation plate 9 prevents it from being removed more than necessary, and always maintains the sand layer in a properly ventilated state.
This is because outside air can be distributed evenly over the entire surface of the ventilation bed 3, allowing aerobic fermentation bacteria to flourish and promoting composting. Since the weight load of the material A is all absorbed by the ventilation panel 9, the sand layer is not accidentally clogged.
