Description

[0001] The present invention relates to a liquid-solid separator for livestock manure,

The present invention relates to a livestock manure solid-liquid separator, and more particularly, to a screw-pressed livestock manure solid-liquid separator for separating livestock manure into solid and liquid portions.

Since livestock manure can be used as a solid compost with a low water content and as a liquid fertilizer with a high water content, it is necessary to separate livestock manure into solid and liquid, The machine is a livestock manure solid-liquid separator.

In general, the solid-liquid separation of livestock manure solid-liquid separator is divided into screen separation, centrifugation, and filtration / pressing. Among them, the pressure filtration is performed by a roller press, (Belt Press), Screw Press (Screw Press) and Filter Press (Filter Press). This solid-liquid separation method is installed and used in consideration of the state of the manure prior to treatment, the treatment method of solid content and liquid after solid-liquid separation, the initial installation cost, required power and maintenance cost.

1, the livestock manure is squeezed by a pressure plate for applying pressure to a screw and a screw so that the liquid is discharged through a net enclosing the screw, The solid material, which is the removed manure, is conveyed along the screw shaft to push out the pressure plate and to be discharged. However, when high pressure is applied to the pressure plate during the work, the water content of the solid is low, but the working efficiency of the machine is low. When the pressure is low, the work efficiency is high, but the moisture is less removed and the high solid content is discharged. Therefore, it is very important to keep the pressure applied to the pressure plate constant as desired in order to maintain the working efficiency while keeping the moisture content of the solid part constant to a desired level.

As a method of applying pressure to the pressure plate, generally, a compression spring and a lever and a weight are used. However, since the thickness of the solid content varies with the change in the amount of the discharged solid matter, the compressive force is not constant and varies. Particularly, since the compression type spring type does not have a solid portion to be discharged at the beginning, the compression is less so that the pressure does not sufficiently take up, and the amount of discharged solid matter tends to be further compressed. According to the embodiment, there is a problem that the desired solid-liquid separation effect can not be obtained because the pressure is low during the first 10 minutes of operation, and a pressure higher than a set pressure is applied when a large amount of solid is discharged.

In addition, the method of using leverage and weight also has a problem in that the angle of the leverage changes according to the thickness of the discharged solid, and the pressure changes due to the change of the angle of the pressure plate connected to the leverage that presses the animal manure.
