Duct cover element for ventilation and manure handling in a barn.

Scope of production

This arrangement relates to a duct cover element for ventilation and manure handling in a stable.

The duct cover element is distinguished by being very stable and robust. The V-shape of the channel cover element and the smooth surface of the concrete enable a self-cleaning effect of the fertilizer in the v-shaped fertilizer channels.

At the same time, the V-shape of the duct deck element enables ventilation ducts and V-shaped fertilizer ducts, via the interconnection of several duct deck elements in extension and arranged in parallel on blocks. Thus, the cross-section of the individual air duct can be adjusted as needed in the form of the height of the blocks. The function of the ventilation duct is to draw the fresh air down to the stable area via ceiling valves and diffuse ceiling. Then, the stable air is drawn further down through the gap area via the embedded air ducts in each side of the v-shaped fertilizer duct. The air is passed to an air purifier at the end of each ventilation duct.

Prior art

The floor forming ventilation ducts (called floor suction) have long been known and used. The two Danish utility model specifications DK 95 00155 and DK 99 00017 describe how the ventilation ducts are placed horizontally below the footbed. At the same time, the fertilizer duct is located in the middle of the ventilation ducts. (See Figure 1). Other traditional solutions are a vertical ventilation duct located beneath the inspection aisle with fertilizer ducts on each side. (See Figure 2). A Danish utility model BR 2004 00050 is a vertical ventilation duct with a curved shape.

The technical problem to be solved in connection with a vertical ventilation duct will require a deep excavation to obtain the same cross-section as a horizontal ventilation duct. The next problem with a horizontal fertilizer channel has a surface for evaporation of the ammonia. The evaporation is very large if the manure (manure) remains in the channel.

The new technique

What is new in the production is that the duct cover element is a V-shape, which enables both a horizontal and vertical system of ventilation ducts and v-shaped fertilizer ducts. The duct deck element has only air ducts in one side. If the duct cover element is rotated 180 degrees, the technical advantage is that air is drawn from both sides in a v-shaped fertilizer duct. At the same time, a v-shaped fertilizer channel is created when duct cover elements are placed opposite each other. Each duct cover element is placed on blocks so that the cross section of the single air duct can be adjusted via the height due to its functionality. During the inspection passage, a circulation pipe for flushing the fertilizer is placed in each v-shaped fertilizer channel.

The technical impact

Applying the above-mentioned technique to the prior art, the duct cover element can be both a horizontal and vertical system of ventilation ducts and fertilizer ducts with a very small ammonia vaporization, the fertilizer area being significantly reduced and air being drawn from both sides of each fertilizer duct.

Figure 3 shows a known vertical duct system BR 2004 00050 Figure 4 shows a duct cover element with both horizontal and vertical system of ventilation ducts and v-shaped fertilizer ducts according to the invention, and Fig. 5 shows a section of the new duct cover element.

Exemplary Embodiments Figure 1 shows a known horizontal duct system with lateral air ducts (1) and manure duct duct (2) in the center of the prior art. The housing air is drawn down through the gap area (3) via the embedded ducts (4) further out into the ventilation ducts (1). In the center there is an aisle (5).

Figure 2 shows a known traditional duct system with air duct (1) in the middle and fertilizer ducts (2) next to it. The fresh air (6) is drawn into the housing area via diffuse air. The housing air is drawn down through the gap area (5) via the embedded ducts (3) in the ventilation duct (1).

Figure 3 shows the connection of several duct cover elements (1) to a vertical ventilation duct (2) via the embedded hooks (3) in the inspection passage (4). The function of the ventilation duct (2) can be exerted via the embedded curved air ducts (5) in the inspection passage (4) which draw the stable air through the gap area (6). The fresh air is drawn in by ceiling valves (10) and diffusive air (11) into the housing area. The curved shape (7) of the duct cover element and the smooth surface (8) of the concrete allow a self-cleaning effect of the manure for the manure gutters (9).

Figure 4 shows an interconnection of several duct cover elements (1) which allows the combination of the horizontal and vertical system with ventilation ducts (2) and v-shaped fertilizer ducts (3). The duct cover elements (1) have only embedded air ducts (4) on one side. If the duct cover elements (1) are rotated 180 degrees, the technical advantage is obtained that the air can be drawn through ceiling valves (9) and diffuse ceiling (10) through the gap area (5) from both air ducts (4) in a v-shaped fertilizer duct (3). At the same time, a v-shaped fertilizer channel (3) is created when the channel cover elements (1) are placed opposite each other. The duct cover elements (1) are placed on blocks (6), so that the cross-section of the individual ventilation duct (2) can be adjusted via the height due to the operation. single fertilizer channel (3).
