Description

Short designation: Storey drying system in which each storey level consists of an air-permeable cloth that functions as a conveyor belt and is separated by air guide plates.

The invention relates to a (re) drying system of poultry, pigs or other type of manure, in which air-permeable transport cloths are placed one above the other and built up in the longitudinal direction from a certain number of connected sections.

Each section is formed by two uprights which are joined in the direction of profiles along the entire length. The sections are made up of a number of cross sections that serve as a transport guide for the transport cloth. The sections can vary in height, resulting in a certain number of shelf levels of transport cloths. The drive stations that ensure the drive of the transport cloth are located at both longitudinal ends of the drying system. The so-called air baffle plates are placed diagonally between the floors across the entire length of the drying system. By means of these plates and the manner in which they are placed, it is achieved that the air coming from the shed is forced to flow through the cloth with the manure lying thereon over the entire length and width of the drying system.

20 As the situation sketch in appendix 1 shows, the entire drying installation can be placed outside, albeit under a roof, at the rear (position A) or longitudinal side (position B) of the house, depending on the position of the existing house fans. The operation of the storey drying system will be explained below with reference to the figures included in appendices 2 and 3.

25 The manure, whether or not pre-dried, from the shed is transferred to the transport cloth of the top floor of the drying system by means of a separate conveyor belt (position A), as shown in the figure in Appendix 2. A fertilizer distribution system (position B), applied at the starting point on the top floor, ensures an even distribution of fertilizer on the canvas. This cloth transports the manure from one (position D) to the other long end of the drying system (position E) via the drive station (position C), after which the manure ends up on the underlying floor.

The manure is then transported from position E to position D on this floor, after which this cycle is repeated for each floor, until all floors are covered with manure. From this moment on, the manure remains on the floors for a certain period of time and is dried with the attracted stable air.

5 The operation of this drying is explained on the basis of appendix 3. The stable air, which is attracted by means of the existing or existing fans, enters directly into the drying system and is spread over the air through the air guide plates (position A). divided length and width under the transport cloths (position B) of the different floors. The air then flows upwards through the cloth and the manure on top. The air then flows out through the air guide plate located above. In this way the manure is dried, whereby the drying time depends on the desired dry matter content. Finally, the dry manure can be transported to a container or storage place via a separate conveyor belt (position F). The different storey levels are turned out in this way, so that the storeys can again be supplied with manure and the above cycle can be repeated. 1 r "7 | ♦ i - 3. / I V«
