Description

The utility model relates to agricultural machinery, in particular, to machines for dehydration of liquid manure.

A device for dewatering is known, comprising a sequentially and coaxially mounted compression screw with a decreasing winding pitch, a moisture fraction control mechanism for the solid fraction having a discharge screw connected by a drive to a compression screw, the pitch of the turns of the discharge screw being equal to the pitch of the last turn of the compression screw, perforated part of the body is made on the inside with segmented recesses parallel to the axis of the screw, and the front radial edge the first turn of the unloading auger is equipped with a cutting insert [Auth. St. USSR SU No. 1155232, class A23N 1/00. Publ. 05/15/85. Bull. No. 18].

However, the known device has several disadvantages, which include the complexity of the design and, as a result, increased material consumption.

The purpose of the utility model is to simplify the design of the device and reduce its material consumption.

The goal is achieved by the fact that inside the housing, coaxially to it, a support is installed, one part of which is made in the form of a hollow cylinder, and the second - in the form of a hollow truncated cone, expanding in the direction opposite to the loading hopper. An unloading pipe is installed on the end part of the housing. On the outside of the perforated part of the housing set casing, equipped with a drain pipe. The lower part of the casing is performed with an inclination towards the drain pipe. The working body is made in the form of a spiral screw, which is installed in the gap between the support and the housing.

In FIG. 1 shows a device for dehydration of liquid manure, General view; in FIG. 2 - same, section along A-A.

The device for dewatering liquid manure contains coaxially mounted in a perforated body 1, a working body 2 made in the form of a spiral screw with a decreasing winding pitch, a loading hopper 3, a drive 4, and also an unloading pipe 5 mounted on the end of the housing 1. Inside of the housing, coaxially with it, a support 6 is installed, one part of which is made in the form of a hollow cylinder, and the second - in the form of a hollow truncated cone, expanding in the direction opposite to the loading hopper 3. From the outside, the perforated part of the housing 1 has a casing 7 provided with a drain pipe 8. The lower part of the casing 7 is made with an inclination towards the drain pipe 8. The working body 2 is made in the form of a spiral screw, which is installed in the gap between the support 6 and the housing 1.

A device for dehydration of liquid manure works as follows.

Liquid manure is fed into the loading hopper 3, in which it is captured by the turns of the working body 2 from the drive 4, made in the form of a spiral screw, and advances to the discharge pipe 5. When the working body 2 rotates, a centrifugal force arises, which discards the water contained in the liquid manure through the perforation of the housing 1 into the inner cavity of the casing 7. Here, water under the action of gravity and due to the inclination of the lower part of the casing 7 towards the drain pipe 8 moves to the drain pipe 8 and is removed through it outward .

Due to the reduction in the step of winding the working body 2, the dehydrated manure is pressed to the discharge pipe 5 during its movement, which creates conditions for a more complete removal of moisture from the dehydrated manure.

In addition, after passing through the first part of the support 6, made in the form of a hollow cylinder, the dehydrated manure begins to move along the second part of the support 6, made in the form of a hollow truncated cone, expanding in the direction opposite to the loading hopper 3. Here, at the same speed of the working body 2, the centrifugal force increases due to a gradual increase in the radius of the support 6, which allows you to remove more moisture from the dehydrated manure.

Dehydrated manure is removed from the device outside through the discharge pipe 5.

The device for dehydration of liquid manure has a simpler design compared to the prototype and less material consumption due to the presence of a simpler body and a hollow support located inside it, one working body instead of two of the prototype, as well as replacing the screws with a spiral screw.
