The present invention relates to a slurry-type livestock manure solid-liquid separation, dehydration apparatus and method thereof, and more particularly, to filter the separated water by solid-liquid separation of slurry-type livestock manure to minimize the concentration of fine particles in the water, long-term operation The present invention relates to a slurry type livestock manure solid-liquid separation, dehydration apparatus and a method for preventing the wedge filter from bursting due to residues remaining in the wedge filter after restarting.

In general, livestock manure refers to manure such as cow manure and pig manure, and the amount of livestock manure is rapidly increasing as the domestic livestock industry is enormous.

Therefore, the goal of using livestock manure is set through the resource policy to organically manure livestock manure for the efficient treatment of large livestock manure, so there is a movement for solution in improving device technology and methods for proper treatment. to be.

In particular, in November 2004, the Ministry of Agriculture, Forestry and Environment jointly announced measures to manage livestock manure, and the method for properly treating livestock manure is separated into solids and liquids (hereinafter referred to as water). Method was adopted.

Accordingly, as a method of continuously processing among the solid-liquid separation methods introduced in the related art, a method using an extrusion screw device is used, and this method uses a chemical input method generally used in the solid-liquid separation process. Did not do it.

Conventional slurry-type livestock manure solids separation device as described above is a method that is installed by connecting a plurality of unit devices and a method that is installed as a single device is used.

On the other hand, of the slurry-type livestock manure solid-liquid separator according to the prior art as described above, the slurry-type livestock manure solid-liquid separator of the method installed as a single device is a screen system, primarily through a screen net having a slope and the screen net It comprises an extrusion screw for extruding and conveying the slurry-type livestock manure in which water contained in the slurry-type livestock manure is removed in one direction.

Here, the slurry-type livestock manure solid-liquid separator according to the prior art is a slurry screened livestock manure discharged from the livestock manure storage tank discharged from the livestock house is introduced through the inlet, the introduced slurry-type livestock manure has a slope First, the water contained in the livestock manure is removed.

After that, the slurry-type livestock manure from which water is first removed is introduced into the extrusion screw device, compressed and transported in one direction, and the introduced slurry-type livestock manure is dehydrated through a wedge filter surrounding the extruded screw to be separated into solids and water. Solids are conveyed in one direction.

At this time, the separated solids in the slurry-type livestock manure in the extrusion screw device is discharged to the solids discharge portion provided at one end of the extrusion screw, the separated water is moisture through the wedge filter gap of the dehydration portion formed in the lower part of the extrusion screw To the outlet.

However, the slurry-type livestock waste liquid separation apparatus according to the prior art as described above had the following problems.

First, the drying phenomenon of residual solids remaining in the dehydration part occurs after summer operation, so that the wedge filter bursts by dry operation which blocks the discharge hole of the dehydration part or operates with the dried residue in the dehydration part. Furthermore, in order to prevent the wedge filter from bursting, it is necessary to disassemble the device every time to clean the inside to remove the dehydrated solids remaining in the wedge filter of the dehydration part after the operation is completed. There was a problem that is difficult to maintain because it is required.

Second, a separate installation area is required to install the screen net, which is a pretreatment device, and it is difficult for unmanned operation due to frequent clogging of livestock hairs or solids between screen nets, and cumbersome maintenance. There was this.

Third, the fine particles pass through the gap of the wedge filter due to the high pressure generated in the process of extruding the slurry contained in the wedge filter of the screw shaft during the dehydration process using the extrusion screw, so that the fine particles float in the water after the solid-liquid separation. There was a problem that the concentration of suspended solids is very high.

Fourth, as the load of slurry-type livestock manure continued during the solid-liquid separation of slurry-type livestock manure, the deflection phenomenon of the screen net frequently occurred, and thus there was a problem in that the cost of the replacement of the net occurred.

Fifth, the screw shaft wrapped by the wedge filter rotates at the center of the device, and the friction between the rotating shaft and the wedge filter cuts the wedge filter due to the deflection of the screw shaft or the deviation of the center of the rotation shaft during assembly. As a result of this, there is a problem in that an additional maintenance cost is generated by shortening the life of an expensive wedge filter.

Sixth, in the case of using the conventional slurry type livestock manure solid-liquid separator in winter, the homogenization occurs due to the increase in the viscosity of the slurry and the freezing of the slurry due to the temperature drop. There was a problem that can not be used.

On the other hand, in most small and medium-sized livestock farms in recent years, there is a need for a large installation space such as a method of connecting several unit devices or a screen-type solid-liquid separator equipped with a screen network as a pretreatment device, depending on insufficient hand and narrow place problems. Simplified and compact liquid-liquid separator is required.
