Description

The invention relates to agriculture and can be used in the purification of manure waste from livestock enterprises.

A device is known for separating organic fertilizers, mainly manure, into solid and liquid fractions, containing an auger with a perforated casing, the last turn of the auger being removed from its main part and installed in a closed casing, and a mesh is installed between the perforated part of the casing and the auger [1].

The disadvantage of the known design is that this scheme is designed for dewatering semi-liquid manure from 80% to 92%, and, as a result, has a low efficiency of the process of separating high-humidity manure into fractions - up to 98% (manure waste).

There is a known design of a device for separating manure into fractions, containing a housing with loading and unloading pipes, a filter element enclosed inside the housing, made in the form of a spring, with a transporting element in the form of a ribbon spiral located in it and connected to a mechanical drive [2].

This device is the closest in technical essence and achieved result.

The disadvantage of the known design is the high humidity of the separated solid fraction of manure waste, as a result of which the solid fraction requires additional dehydration in order to meet sanitary and hygienic requirements and be suitable for biothermal disinfection and further use as a valuable organic fertilizer.

The purpose of the claimed invention is to reduce the moisture content of the solid fraction of manure waste.

This goal is achieved by the fact that the device for separating manure waste into fractions contains a housing with a supply pipe connected to a receiving chamber, an inclined perforated panel with a liquid fraction collector placed underneath it with an outlet pipe and a solid fraction receiver. In this case, above the inclined perforated panel with a gap, parallel to the latter, a sedimentation plate is rigidly fixed, and the upper edge of the sedimentation plate along the entire width is made concave in the direction of the flow, and is outlined in a particular design, along a circular arc.

The figure shows a general view of the device.

The device for separating manure waste into fractions contains a housing 1 with a supply pipe 2 connected to a receiving chamber 3. An inclined perforated panel 4 is installed inside the housing 1, with a liquid fraction collector 5 underneath it in the housing 1 with an outlet pipe 6 and a solid fraction receiver. 7.

In parallel, above the inclined perforated panel 4 inside the housing 1, a sedimentation plate 8 is rigidly fixed, installed with a gap relative to the inclined perforated panel 4, and the upper edge 9 of the sedimentation plate 8 along the entire width is made concave in the direction of flow, and is outlined in a particular design, along an arc of a circle .

A device for separating manure waste into fractions operates as follows.

The initial suspension of manure waste under pressure through the supply pipe 2 enters the receiving chamber 3 and enters the sedimentation plate 8, where it is divided into precipitated and clarified phases due to the gravitational forces of thin-layer sedimentation. Moreover, heavier solid suspended particles of the sedimented phase of manure drainage move down along the inclined sedimentation plate 8 due to the difference in the effects of gravity and the friction force of the sediment on the surface of the plate and enter the solid fraction receiver 7. The clarified phase of the manure drainage moves up along the surface of the sedimentation plate 8 and, overflowing through the upper concave edge 9, is distributed along the inclined perforated panel 4, through which it is filtered, separating into solid and liquid fractions of manure waste. The solid fraction formed on the perforated panel 4 slides off the latter due to the forces of the difference between friction and gravity and is removed from the device through the solid fraction receiver 7, and the resulting liquid fraction enters the liquid fraction collector 5 and is discharged through pipe 6.

Due to the fact that the suspension of manure waste is divided into solid and liquid fractions, first on a sedimentation plate, and then filtered on an inclined perforated panel, the resulting sludge of the solid fraction has a lower humidity, is suitable for biothermal disinfection and can be used for disposal as a valuable organic fertilizer .
