JPS59133993A - Device for removing extraneous material from sewage in water or liquid - Google Patents

Abstract

PURPOSE:To provide a titled device which can easily and quickly separate the extraneous material in sewage by the constitution wherein the sewage introduced into a circular cylinder is pressurized to separate and discharge the water through the filter holes provided on the cylinder wall and the remaining extraneous material is pulverized and taken out. CONSTITUTION:A circular cylinder 1 is segmented by means of a partition plate 2 opened in the central part to a filter chamber A and a chamber B for discharging extraneous material. Sewage is introduced from a hopper 4 into the chamber A and a pressing piston 12 attached with a rubber plate 9 on the front face is advanced gradually by the operation of a motor 18 and a screw rod 18 to press the sewage so that only the water through the filter holes 5 extended with plural sheets of screens 6, 6'... is discharged to a liquid discharge path 8. The extraneous material remaining in the chamber A is pressed by the piston 12 and is hardened on a pulverizing plate 15 provided in the position coinciding with the aperture of the plate 2 and then the plate 15 and a revolving screw 16 are rotated by a revolving shaft 14 to pulverize the extraneous material. The ground material is transferred into the chamber B from which said material is discharged through a discharging port 17 for the extraneous material.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is intended to reduce impurities in human waste water discharged from household flush toilets, or BOD and C in live water discharged from various shellfish factories.
Highly efficient separation and removal of impurities in water (hereinafter simply referred to as SS), including fine surplus sludge continuously discharged from OD purification and civil engineering works, etc. The present invention relates to a device for removing sewage contaminants from an aqueous liquid.

Conventionally, when removing SS from sewage discharged from households, extremely large particles of 8 days can be removed using a centrifugal separator, except for the disadvantage of increasing the size of the equipment, but other fine particles of SS can be removed using a centrifuge.
Furthermore, there is no ability to efficiently remove the excess sludge from the sewage discharged from each Kusunoki factory. IJ! is made by mixing SS containing a lot of water with lime and other sludge! This is due to the fact that secondary treatment problems of excess sludge in the form of sludge will eventually occur, and each treatment department must take decisive action to remove sludge from aqueous liquid. The one that is missing is the one that has a glare shape.

In addition, during civil engineering work such as horizontal hole digging for underground tunnel construction, coarse rocks can be easily separated from the excavated earth and sand that contains a variety of moisture, but among this, mud containing fine soil can be easily separated. The treatment of the aqueous liquid that has become
The only method available is to discharge the soil and water by a pump or the like and allow the natural sedimentation of the soil to separate the soil and water, and this separation process cannot be carried out easily or quickly.

The invention was created in order to highly efficiently separate SS mixed into such aqueous liquid using a simple device,
After dividing the inside of the Maruyama (Maruyama) shaped cylinder into left and right parts and allowing aqueous liquid mixed with fine SS to flow into the cylinder, this is pressurized at low speed with a pressurizing piston to form a hole in the curved surface of the cylinder and to form a liquid on its outer circumferential surface. Only water is discharged through a filter hole with several screens stretched over it, and a fine SS body that remains in the cylinder and hardens under pressure is inserted from the other side of the cylinder and a drilled hole is inserted into the tip of the cylinder. The aqueous liquid is loosened by a crushing plate and discharged to the other end of the cylinder by a rotating screw, and the aqueous liquid is automatically mixed with SS by the movement of a pressurizing piston that moves inside the cylinder. It is designed to easily and quickly separate moisture and SS from the inflow of water, and in the history of sewage treatment in each household and wastewater treatment at each yuzu factory as mentioned above, it is necessary to meet the demand for treatment at civil engineering facilities. This is extremely useful as it can be easily installed depending on the situation.

To explain one embodiment of the wooden invention based on the drawings, a cylindrical cylinder il+ is divided into a filtration chamber (c) and a discharge chamber GB) by a dividing plate (2) rounded at the center.
