Embodiment Construction

[0019] The screw pressure dehydrator of the present invention will be described more fully hereinafter with reference to the accompanying drawings, which show representative embodiments of the invention.

[0020] As shown in FIGS. 1 and 2 , the screw pressure dehydrator has an outer cylinder 11 including a pressurized chamber 25 , a liquid substance discharge chamber 28 and a lump discharge chamber 29 . On the pressurization chamber 25 there is a waste water inlet 21 through which waste water flows. On the liquid substance discharge chamber 28, there is a liquid substance outlet 22 for discharging the escaped liquid substance. There is a lump outlet 23 on the lump discharge chamber 29 , a portion of which has an opening, through which lumps formed of compressed solid matter are discharged.

[0021] A porous cylinder 12 is provided inside the liquid substance discharge chamber 28 , and a metal filter 13 is joined on the inner circumference of the porous cylinder 12 .

Abstract

The invention relates to a screw pressure evaporator used for the waste water treatment, which is used in the process for removing the liquid matter from the waste water in the food industry. A porous cylinder in the cylindrical shape is arranged inside the outer tube, and the cylindrical metal filter is arranged inside the porous cylinder. The screw wiper blade of the rotary worm scrapes the solid matter filtered by the metal filter, and a movable regulating stop piece is inserted in the rotation axis for adjusting the size of the lumpy object export. The liquid matter in the waste water led from the waste water entry flows through the metal filter, thereby discharging singly through the liquid matter export. The solid matter in the waste water is compressed by the crew wiper blade of the rotary worm thereby forming the lumpy object which is then discharged singly from the lumpy object export.

Description

technical field [0001] The present invention relates to a screw pressure dehydrator for waste water treatment, applied in the process of removing liquid matter from waste water in the food industry, wherein oil is extracted from fruits such as palm fruit by using hot water on the fruit, and / or applied to in the livestock industry. Background technique [0002] Dehydration is critical in the wastewater treatment process to clean wastewater from the food industry and / or livestock industry before it flows into rivers or marine areas in order to prevent water pollution. [0003] In the wastewater treatment process, when using a filter, the solid matter in the wastewater, especially the fine solid matter, can be quickly separated from the liquid matter in the wastewater. Therefore, filters are widely used to separate solids from sewage, food industry wastewater, and livestock industry wastewater. Different types of dehydrators with filters have been developed and used. For exa...
