Description

SUMMARY OF THE INVENTION The present invention relates to a device for ventilating multi-storey stables with cage rearing, particularly suitable for large-scale breeding.

Nowadays, for large-scale production of livestock, especially poultry, it has been converted to a concentrated form of meat production or breeding using cage rearing, since this method allows a significant use of the built-up area.

This form of mass production entails problems affecting the appropriate climate for concentrated animals in cages.

Known cage rearing are located in single-storey buildings where transverse ventilation is used. However, there are problems with the quality of climate creation in terms of the width of the halls, as these objects are difficult to air-conditioned in the case of greater width in relation to the clear height.

In the case where the cages are stacked to a considerable amount and the cages were operated by ladders, transverse ventilation with roof chimneys was again used. However, this method was not particularly satisfactory due to the blind spots in the central rows of cages, and the ladder inspection has also proved to be rather progressive. There was considerable mortality, despite the difficulty in handling animals.

Attempts were also made, and in several cases, multi-storey buildings with a collapsible collateral were implemented, where transverse air conditioning was again used. Multi-storey objects however

199 868 by their design created complicated branches of air-conditioning equipment on each floor and especially during the demanding and positive construction of individual floors of wide halls, there were constitutional difficulties in reinforcing the halls, which limited the cage and feed and service lines in all off-roof floors.

These drawbacks are overcome by ventilation of the multi-storey stallions with stallion rearing according to the invention, which consists in that the discharge fans are housed in floor air ducts covered by a perforated platform, located between rows of multi-tier cages defining vertical ducts vertically divided by alternately impermeable footbridges. and by means of footbridges c vents which are arranged offset in each case in the seat channels, the suction fans being located in the upper part of the ventilation object. Furthermore, it is essential that humidifiers and heat exchangers are housed in the floor air ducts.

The advantages of this device are manifested in considerable savings of the built-up area when compared with the currently constructed single-floor objects. Due to the high concentration of breeding poultry per unit area, when solving the vertical air conditioning of several multi-row cage cages, communication and engineering networks are cheaper.

Significant savings will arise in the purchase price of air-conditioning equipment, feed lines, faeces removal, since the installation of these devices with multi-storey cages simplifies the systems in terms of the cost of the number of individuals kept.

Increased levels of egg containerization and picking of poultry via tubular downtimes will be used here.

The amount of workforce per number of individuals will be reduced, and in this respect the consumption of energy spent on air conditioning and line mechanization will also be reduced. It is increasingly applied to all automation processes.

Significant savings will be reflected in the comparison and single-floor rearing system, but also a system of multi-storey poultry rearing, objects with classic solid floors. The above-mentioned ventilation principle with the help of fixed footbridges and footbridges suspended on reinforced cage frames saves one of the most important construction costs, namely the cost of constructing the floors of the upper floors of multi-storey buildings.

With this solution, the space of the building is maximally utilized, as there is no need to reduce the handling space, which in the case of classic multi-storey buildings occupied the reinforcements and supporting columns. The variability of the building during the change of technology is high, because after the cages and air-conditioning systems are dismantled, the empty building with a large subsoil remains.

An exemplary embodiment of the device according to the invention is shown schematically in the enclosed drawing, wherein Fig. 1 is a side elevation of the device; Fig. 2 is a plan view of a part of the subsoil without cages and footbridges.

Air ducts 2 are formed in the subfloor 1 along the entire length of the floor, in which heat exchangers fa, humidifiers 6 and discharge fans J are arranged. The air ducts 2 are covered by a perforated platform 6 which is hinged at the beginning of the air ducts 2 in a solid podium Jg. Between the rows of perforated stages 6 are located rows of multi-bay cages 11. Between these rows of multi-bay cages

I, 1 are steadily suspended alternately with gangways 2 with vents, and impermeable footbridges 8. The space below the footbridges 2 β vents, limited by two rows of multi-storey cages 11, is the space below the footbridge β vents 13,

II. is the space under the impermeable footbridge χ. The space above the multi-collection cages 11 is a discharge space 14. where suction fans are located at the highest point of this discharge space 14

12.

The exhaust fans 2 draw air from the space of the air-conditioned object, the air being humidified by the humidifier and heated to the optimum temperature by means of the heat exchanger 2 and further forced by the floor air ducts 2, through the perforated stage J into the space between the rows of , directly vertically openings in footbridges 2 into the space under the impermeable footbridge where the air is forced to pass in a horizontal direction a section of multi-deck cages 11 up to the space under the footbridges 13 where the air direction changes again in vertical and passage in the footbridges 2 gets into the space under the impermeable footbridge

The air flow direction is then repeated by analogy.

Or, if the air exits from the floor air ducts 2 through the perforated stage χ to the space below the impermeable footbridge 2 »changes its flow direction to horizontal, it passes through the section of multi-deck cages 11 to the space below the footbridges. it turns into vertical again, the openings in the catwalks 2 with the vents pass into the space under the impermeable catwalk 2 ^{and the} flow sensor repeats again analogously

Because of the passage of air through all the defined sections of the multi-storey cages 11, air is sucked out by the suction fans 12 into the atmosphere above the closed object in the upper discharge space 14.

Access to the stairwells 2, or the impermeable footbridges 6 in the individual floors, is provided by means of marked steps, which are located in the edge of the fixed stage 10 and on the other floors are alternately inclined in the vertical axis.

The use of the device according to the invention is particularly suitable for breeding poultry and, with sufficient cage stabilization, also for pig or calf breeding.
