Description

Technical field

The present invention relates to a mobile biofermenter comprising a thermally insulating jacket and an air supply and exhaust device.

BACKGROUND OF THE INVENTION

Previously known biofermentors are stationary, large and massive concrete boxes with solid doors, equipped with a set of fans for air inlet and exhaust from the interior of the biofermentor. A mixture of absorbent material, e.g. straw, sawdust and waste from primary agricultural production and after the door is closed, a biofermentation process takes place in the interior where a valuable fertilizer is produced by aeration with the supplied air. A disadvantage of known biofermentors is that, due to the known monolithic reinforced concrete construction, this device cannot be used as a mobile device.

SUMMARY OF THE INVENTION

These drawbacks are largely eliminated by a mobile biofermentor consisting of a thermally insulating jacket and equipped with an air inlet and outlet device, which consists in that the thermo-insulating jacket comprising the sides, ceiling and door of the mobile biofermentor consists of shaped plates whose surface it is equipped with a system of ribs on which the thermal insulation boards adjoin and thus form closed air gaps in the thermal insulation jacket. The heat-insulating jacket is placed in a frame which is connected to the base of the mobile biofermentor. Essentially, channels are provided which are open to the interior of the mobile bio2 fermenter and accommodate tubes connected to a common source of pressurized air having exhaust ports.

The mobile biofermentor makes it possible to obtain valuable organic fertilizer by perfect thermal insulation and construction, wherever the biofermentor is mobile thanks to its design.

In order to improve the heat-insulating properties, it is advantageous if the base consists of a hollow steel body, which is filled with a heat-insulating material and is provided with handling clips for ease of transport.

In order to improve the fermentation process in the mobile biofermentor, it is advantageous if a pipe is connected to the suction side of the common source of compressed air leading to the upper region of the interior of the mobile biofermentor with its other end.

For ease of maintenance and operation of the mobile biofermenter, it is advantageous if the thermal insulation sheath is covered with a set of cover plates and on the outside of the door a pivotable double-lever lever is swiveled with its shorter end abutting in the closed position the double-reversible lever is locked in the closed position by a fuse.

In order to prevent clogging of the exhaust openings in the tubes by a charge, it is advantageous if the tubes in the channels are covered with crushed mineral material to the level of the upper surface of the base.

DETAILED DESCRIPTION OF THE INVENTION

The mobile biofermentor of FIG. 1, consists of a base 7 on which a heat-insulating sheath 1 is placed in a steel frame 22, which is fixedly connected to the base 7, thereby forming the ceiling, sides and doors 2 of the mobile biofermentor. The heat-insulating sheath (see FIG. 2) consists of polypropylene molded plates 3, from which the ribs 4 project, both horizontally and vertically. Adjacent to the fins 4 are insulating boards 5 of polystyrene and glass or mineral wool, so that closed air gaps 6 are formed in the insulating jacket 1. The outer surface of the insulating jacket 1 is formed by a system of cement-chip surface panels 17. The inner walls are equipped with inner reinforcement 25 to prevent damage.

The base 7 (see FIG. 3) consists of a hollow steel body 12, which is welded from plates and profiles and is filled with a thermally insulating material 13 which is perlite. In principle 7, channels 8 are formed which are open into the interior 28 of the mobile biofermentor and in which the polyethylene tubes 9 are mounted, connected via a collecting channel 27 (see FIG. 4) to a common compressed air source 10, in this case a fan. The tubes 9 are provided with exhalation openings 11 and are buried in the channels 8 at the level of the upper surface of the base 7 by crushed mineral material 26.

In the upper region of the interior space 28 of the mobile biofermentor, see FIG. 5) a pipe 16 is installed which is connected to the suction side of the common compressed air source 10 via a distributor 15. The manifold 15 is a flap that allows to control the ratio between the air drawn in from the atmosphere and the air drawn in from the interior 28 of the mobile biofermentor.

The door 2 of the mobile biofermenter is rotatably mounted on the frame 22 (see FIGS. 6, 7) and is pushed onto the sealing surfaces in the closed position by a double-reversible lever 18 which is pivotably mounted on the outside of the door 2 so that its shorter end U? abuts in the closed position on the inner surface 20 of the stop 21 and the longer end 23. by which the tube is slightly bent, it is locked in the closed position by a sliding fuse 24.

Biological wastes from primary agricultural production, eg pig manure, chicken droppings, beef manure, or wastewater treatment plants, or other natural wastes are mixed with absorbent materials such as straw, sawdust, crushed bark and the like. The mixture is allowed to stand for about 2 days, warming to a temperature of about 40 ° C. After reaching this temperature, the mixture is transported by a loader to a mobile biofermentor. After the biofermentor door 2 is closed, the mixture itself gradually heats up to a temperature of 75-80 ° C due to the highly effective insulation of the thermal insulation sheath 1. A common compressed air source 10 blows air through the collecting duct 27 into pipes 9 from which air enters the interior 28 of the mobile biofermentor through exhaust ports 10, permeates the stored mixture, aerates it, and either exits free into the atmosphere in the upper region. In the installation of the recirculation system, the heated air is fed via line 16 to the manifold 1.5, where it is mixed with atmospheric air in a set ratio and again injected into the mobile biofermenter via a common compressed air source 10.

The common compressed air source 10 is switched on the basis of a known and not shown control system.

The mobile biofermentor can be loaded onto the vehicle and connected to another location after connecting the crane ropes to the handling clips 14.
