Description

Liquid manure separation device

The utility model relates to the field of agriculture and can be used in livestock complexes in systems for preparing liquid manure for irrigation.

Known systems for separating liquid manure into fractions, including horizontal sedimentation tanks-manure reservoirs with drainage and filter elements, passing through which the liquid fraction enters the reservoirs (Novikov V.M. et al. Mechanization of cleaning and disposal of manure. M .: Kolos, 1982, p. .80-83).

The disadvantage of such systems is the rapid siltation of the drainage and filters of sedimentation tanks, manure accumulators, and therefore, their low throughput and the need to clean or replace drainage and filter elements.

The prior art design of glasses made of polymeric materials, the walls of which are made with the possibility of folding parallel to each other (Aut. St. USSR No. 1713549, square A 47G 19/22, 1992).

Closest to the technical nature of the claimed utility model is a sludge separator for liquid slurry containing a calcium receiving tank with vertical perforated walls located on a waterproof base having a drain into the water intake device (Aut. St. USSR No. 1802982, AO1 S 3 square. / 00.1990).

However, the configuration of the inner part of the sump does not allow high-quality discharge of the solid fraction of manure and requires large expenditures of manual labor for cleaning.

The objective of the invention is to improve ease of use and reduce the cost of manual labor.

The problem is achieved in that in the device for separating liquid manure, the perforated walls are made of separate rings with inverse taper, providing it with folding capacity, and the base has an annular niche; it has the dimensions of folded rings, while the adjacent rings are equipped with controlled hooks, and the upper the ring is connected to hydraulic cylinders installed around the perimeter of the niche in the walls of the base.

The technical result of the proposed solution is ensured by folding the walls of the receiving tank into a niche of a waterproof base, which allows unloading of the solid fraction of manure by any means of transport, for example, a bulldozer, moving the manure from the surface formed by the base and the rings laid in the niche.

Figure 1 shows a diagram of the device in working condition, figure 2 diagram of the device when folded.

A device for separating liquid manure contains a feed unit 1 of liquid manure in a receiving tank, the walls of which are made in the form of perforated rings 2 with inverse taper. Adjacent perforated rings 2 have steered hooks 3.

The lower ring 4 of the receiving tank is made of concrete and installed in an annular niche 5, which is designed to collect and discharge the liquid fraction of manure. Niche 5 is built in a concrete base 6 and has the dimensions of folded perforated rings 2. However, the lower ring 4 is made with perforated concrete floor 7 and holes 8 in the walls to pass the liquid fraction.

Along the perimeter of the niche 5 in the walls of the concrete base 6, at least three hydraulic cylinders 9 are installed to lift the perforated rings 2, connected to the upper ring of the receiving tank. Niche 5 has a water outlet 10 for discharging the liquid fraction of manure into the intake device (not shown in the figure).

A device for the separation of liquid manure works as follows;

With the help of hydraulic cylinders 9, the perforated rings 2 rise in turn, starting from the top, and form a receiving tank into which liquid manure enters through the feed unit 1. As the tank is filled, the liquid fraction of the manure flows into the niche 5 through the perforation of the rings 2 and the overlap 7 of the lower ring 4. From where it is discharged into the intake device via the outlet 10.

After filling the receiving tank with a solid fraction of manure and stopping the liquid filtration, the perforated rings 2 with the help of hydraulic cylinders 9 and controlled hooks 3 are lowered into the niche 5 parallel to each other, starting from the bottom.

The hooks 3 are controlled by the vertical force generated by the hydraulic cylinders 9 when folding, and subsequent hooks are triggered alternately starting from the bottom.

After the perforated rings 2 are folded into a niche 5, the solid fraction of manure is on the surface of the concrete base, the bis is shifted from the site using a vehicle.

Then, in turn, starting from the top, the perforated rings 2 rise and are simultaneously washed with clean water or a liquid fraction of manure, and the washings are sent for re-separation.

Alternately folding the perforated rings 2, starting from the bottom, prevents the solid fraction from entering the niche 5.

Claims (1)

A device for separating liquid manure containing an annular receiving tank with vertical perforated walls located on a waterproof base having a drain into the intake device, characterized in that the perforated walls of the receiving tank are made of separate rings with reverse taper, which provides folding of the tank, and the base is constructed with an annular niche having the dimensions of folded rings, while the adjacent rings are provided with controlled hooks, and the upper ring is connected to the hydraulic cylinders, installed around the perimeter of the niche in the walls of the base.
