Abstract

A cleaning device of a screw press for filtrating and dehydrating garbage in which a plurality of dehydrate liquid guide grooves are circumferentially formed on an inner surface of a support cylinder which supports an outer surface of the filtration cylinder so as to permit the support cylinder to be less in contact with the filteration cylinder. Moreover, a dehydrate fluid is discharged through discharging holes, thereby improving filtration efficiency. In addition, a compression air, a pressurized water or high pressure steam is injected from the circumferential surface of a screw being rotated within the filtration cylinder to enable garbage remaining at a plurality of filtrating holes to be completely and cleanly discharged outside, thereby enhancing filtration effectiveness.

Claims

1. A screw press for filtrating and dehydrating garbage, comprising:

a plurality of dehydrate liquid guide grooves circumferentially formed on an inner surface of a support cylinder having a plurality of holes and outwardly supporting a filtration cylinder disposed inside a single body, wherein a filtrated and dehydrated fluid is guided by a cleansing matter along the guide grooves so as to be discharged through the plurality of the holes of the support cylinder;

a tube-type rotating shaft mounted to a supply port connected to a tapered cylinder forming a screw inside the filtration cylinder, the screw comprising a protruded circumferential surface, wherein the supply port supplies the cleansing matter to a plurality of fluid supply holes located in the tapered cylinder;

a supply pipe connected to the fluid supply holes for transporting cleansing matter;

an injection pipe attached at regular intervals along the protruded circumferential surface and connected to the supply pipe for transporting cleansing matter; and

,

injection holes located at regular intervals along the injection pipe for discharging the cleansing matter.

2. The screw press of claim 1, wherein the injection pipe is welded to the protruded circumferential surface of the screw.

3. A screw press for filtrating and dehydrating garbage, comprising:

a support cylinder having a plurality of holes and an inner surface;

a filtration cylinder disposed inside the support cylinder;

a supply port for supplying cleansing matter;

a tapered cylinder connected to the supply port and having a protruded circumferential surface forming a screw disposed inside the filtration cylinder, wherein the tapered cylinder further comprises a plurality of supply holes, each supply hole connected to a first end of a supply pipe, and an injection pipe connected to a second end of the supply pipe, wherein the injection pipe comprises a plurality of injection holes located at regular intervals along the protruded circumferential surface of the screw such that cleansing matter is forced from the supply port through the injection holes at a high pressure;

a rotating shaft connected to the tapered cylinder; and

,

a plurality of dehydrate liquid guide grooves circumferentially formed on the inner surface of the support cylinder and aligned with the injection holes such that the cleansing matter and guide grooves guide a filtrated and dehydrated discharge fluid through the plurality of holes on the support cylinder.

4. The screw press of claim 3, wherein the injection pipe is welded to the protruded circumferential surface of the screw.

5. A screw press for filtrating and dehydrating garbage, comprising:

a support cylinder having a plurality of holes and an inner surface;

a filtration cylinder disposed inside the support cylinder;

a supply port for supplying cleansing matter;

a tapered cylinder connected to the supply port and having a protruded circumferential surface forming a screw disposed inside the filtration cylinder, wherein a plurality of injection holes are located at regular intervals along the protruded circumferential surface of the screw so that cleansing matter is forced from the supply port through the injection holes;

a rotating shaft connected to the tapered cylinder; and

,

a plurality of dehydrate liquid guide grooves circumferentially formed on the inner surface of the support cylinder and aligned with the injection holes such that the cleansing matter and guide grooves guide a filtrated and dehydrated discharge fluid through the plurality of holes on the support cylinder.

6. The screw press of claim 5, wherein the tapered cylinder further comprises a plurality of supply holes, each supply hole connected to a supply pipe at a first end, and an injection pipe connected to a second end of the supply pipe, wherein the injection pipe comprises the plurality of injection holes.

7. The screw press of claim 6, wherein the injection pipe is welded to the protruded circumferential surface of the screw.
