The present invention relates to a fertilizer fermentation device in which an air preheater is installed, and installs an air preheating compartment behind the fertilizer fermentation tank and conducts radiant heat by conducting radiant heat by conducting high heat generated in the fertilizer itself. The purpose is to prevent the waste of energy and the shortening of fermentation ripening time by supplying air preheated to a certain temperature in the tank by installing a pipeline.

Recently, animal waste from rural areas, primary industrial wastes such as berths, saws and vegetable waste, and sewage, sewage sludge, and food waste from households are collected separately and collected in a certain place. When fermentation of microorganisms while maintaining adequate humidity and supplying oxygen for 10-15 days as a simultaneous blower, there is no odor, and parasites and malignant bacteria are extinguished. Nitrogen, phosphoric acid, Kari, organic matter and moisture are about 20% respectively. The process of converting reduced and acidified soils to alkaline and obtaining a mature fermented compost fertilizer rather than a conventional organic fertilizer of high performance containing a large amount of microorganisms necessary for plant growth is widely used.

Therefore, when looking at the conventional fermentation apparatus for obtaining the compost manure as shown in Figures 1 and 2, the front wall is opened and closed at the bottom of the fermentation housing (not shown) manufactured to a predetermined size The remaining both side walls and the rear are closed as concrete walls of a predetermined height, and at the same time a plurality of container-type fermentation tanks 1 'having an open top are laterally adjacent to each other and at the bottom of each fermentation tank 1'. Oxygen supply pipe (2 ') connected to the blower (3') of the array is arranged therebetween, the support neck (4 ') is installed between the porous plate (5') for loading fermentation material thereon is listed above Various waste materials such as bar can be contained.

Each waste fermentation tank (1 ') configured as described above contains various waste materials and starts to supply oxygen as the blower (3'). After 3-5 days, the internal temperature of the waste materials fermented as the microorganisms are fermented is 85 If the fermentation process continues for 10-15 days, the fermented fertilizer will be obtained.

However, in supplying oxygen as the blower 3 'during the process, the most suitable supply temperature for fermentation of microorganisms is 25-30 ° C., and the above conditions are satisfied only in summer, at high temperature and high humidity. In the rest of the season (particularly in winter), the water temperature drops considerably, so it takes about twice as long as the summer season to obtain fermented fertilizer. Since energy is consumed, manufacturing costs are increased.

Therefore, in order to solve the above problems, the present invention forms an air preheating compartment at the rear of the fermentation tank in which the blower is located, and receives heat generated from the waste being fermented in both side walls of the tank to receive the inside of the compartment. By installing a closed circulation pipe filled with a material to radiate and preheat the air in the compartment through the protruding part, the combustor is always composted in a predetermined period, so that oxygen can be supplied as a blower at a predetermined temperature at any time under any outdoor condition. To produce and supply fertilizer.

This will be described in more detail with reference to the accompanying drawings.

That is, the rear and both side walls excluding the opening and closing front wall 11 in the open state is sealed with a fixed structure, a plurality of oxygen supply pipe (2) arranged in connection with the rear blower (3) on the bottom surface, In the ordinary one in which at least one fermentation tank 1 containing the perforated plate 5 and the supporting base 4 is arranged side by side, a blower as shown in FIGS. 3, 4, and 5 At the rear of the fermentation tank (1) in which (3) is located, a compartment (7) having at least one air inlet (71) is formed, and in both side walls (12) of each fermentation tank (1), The heat transfer part 61 for radiant heat transfer in the compartment 7 is projected by a predetermined length, and the closed circulation conduit 6 filled with a heat transfer material (ordinary material) is wound inside the compartment 7, and is not described in the drawings. 62 is the release of bubbles generated during circulation of the heat transfer material located in the circulation line (6) Or a supplemental reservoir for loss supplements.

The present invention configured as described above, the start of supplying coral as a blower (3) to the various wastes loaded on the porous plate (5) in the fermentation tank (1), and after 3-5 days have elapsed the microorganism fermentation becomes active inside The temperature is maintained at 85-100 ℃, the heat generated there is transferred to the heat transfer material in the circulation conduit 6 through both side walls 12, so that the heated heat transfer material circulates inside the circulation conduit 6 Radiant heat transfer is carried out from the heat transfer part 61 into the compartment 7 to heat the air in the compartment 7 introduced through the air supply port 71 to a predetermined temperature.

Therefore, the oxygen supplied into the tank by the blower 3 is preheated and supplied at a temperature suitable for microbial fermentation, so that no matter how winter, the compost fertilizer can be produced and supplied in the same period as summer, and the blower operation time is shortened accordingly. There is an extraordinary effect that can prevent the rise of manufacturing cost of products and improve productivity.

Claims (1)

On the bottom surface, a plurality of oxygen supply pipes (2) connected to the rear blower (3), and at least one fermentation tank (1) arranged horizontally between the supporting plate (4) for supporting the porous plate (5) therebetween In the conventional installation, a compartment 7 having at least one air supply port 71 is hermetically formed at the rear of the fermentation tank 1 in which the blower 3 is located, and each fermentation tank 1 In each of the side walls 12, an air preheating device is installed, which comprises a heat transfer part 61 projecting into the compartment 7 and a circulation conduit 6 filled with a heat transfer material is wound.
