Abstract

PURPOSE:To continuously sediment a sediment by feeding sewage, etc., to a centrifugal separator. CONSTITUTION:A mixed liquid which collects in a mixed liquid intake from a mixed liquid guide pipe 6 sediments a sediment by a vessel type filter 2 through an exhaust guide pipe 1. In that case, since an angle rotor is rotated by a motor 5, centrifugal force is applied and the sediment is sedimented in a short time, and clear water is drained from a small specific gravity matter fetch nozzle 7.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a centrifuge filter for centrifuging a mixed solution having contents having different specific gravities, filtering one of them and precipitating the other.

[0002]

2. Description of the Related Art When separating a conventional mixed liquid into purified water (the term "purified water" here means water that does not impair sanitation) and a precipitate, a method of filtering with a ceramic filter is used. In the case of precipitation, there are a method of providing a precipitation layer and a method of using a centrifuge.

[0003]

In the conventional method, when a ceramic filter was used for filtration, clogging occurred immediately. Further, in the case of performing precipitation in the precipitation layer, a precipitation layer and a precipitation tank were put in, and in any case, the apparatus became large in scale. Furthermore, when a centrifugal separator was used, it was difficult to continuously take out purified water only in the case of the angle rotor type, and when the rotating drum was used, the precipitate contained purified water. The present invention is to solve the above-mentioned problems, in which the mixed liquid discharged from the jet guide pipe (1) using an angle rotor type centrifugal separator continuously deposits on the container type filter (2). The purpose of the present invention is to provide a centrifugal filter for precipitation.

[0004]

In order to achieve the above object, the mixed liquid is guided from the mixed liquid intake (4) to the central portion of the container type filter (2) through a jet guide pipe (1). The centrifugal force is applied to the container type filter (2) by the motor (5). The overflowed purified water was scattered on the machine frame (3) and was taken out from the small specific gravity material take-out nozzle (7) to achieve the purpose.

[0005]

In the centrifuge filter of the present invention, the mixed liquid guided from the jet guide pipe (1) to the central portion of the container type filter (2) is caused to flow little by little, whereby a precipitate of large specific gravity and a small specific gravity are obtained. The water is separated into purified water and the precipitate is directly deposited on the bottom of the container type filter (2), and the small specific gravity substance overflows the container type filter (2). However, this takes time, so by rotating the entire angle rotor by the motor (5) and applying centrifugal force, the difference in specific gravity between the large specific gravity material and the small specific gravity material in the container filter (2) is reduced. Larger and shorter separation time. Then, the overflowed small specific gravity material is scattered on the machine frame (3) and taken out from the small specific gravity material extraction nozzle (7).

[0006]

EXAMPLES Examples of the present invention will be described below. (B) When this centrifugal separation filter is used as a wastewater purifying device, the mixed solution inlet pipe (4) is introduced through the mixed solution guide pipe (6).
By gently flowing the mixed solution from the bottom of the container type filter (2) through the jet guide pipe (1) at an appropriate position, large specific gravity is precipitated in the container type filter (2), Specific gravity overflows from the container filter (2). However, this takes too much time, so the centrifugal difference is applied to the container-shaped filter (2) by the motor (5) to increase the difference in specific gravity. (Explaining it in the figure, the container-shaped filter (2) indicated by the double-dotted line in FIG. 1 is in a state where it is not rotating and the state indicated by a solid line is rotating.
The right half of FIG. 2 is in a rotating state, and the left half is in a stopped state. The purified water of the small specific gravity overflowing from the container type filter (2) is discharged from the small specific gravity extraction nozzle (7) through the machine frame (3). Then, the motor (5) is periodically stopped and the container type filter (2) is removed to take out the deposits accumulated therein. At this time, since the container-shaped filter (2) is only hooked by the container shaft (8) and the hooking portion (9), it can be easily removed. Therefore, by preparing a spare of the container type filter (2), the time for stopping the centrifugal separation filter can be shortened. (B) Similarly, when the centrifugal filter of the present invention is used as a filter for soot and so on, the soot and smoke sent to the mixed liquid intake (4) also passes through the jet guide pipe (1) and passes through the container type filter (2). The soot and smoke particles are stored in the bottom of the container-shaped filter (2), and the remaining gas is discharged from the small specific gravity material extraction nozzle (7) through the machine frame (3). (C) Since it is a device for separating substances by such a specific gravity, there is a method in which purified water of a small specific gravity is further filtered by a ceramic filter after being separated by this centrifugal separation filter. Furthermore, by providing a small-scale sedimentary layer in front of this centrifugal separation filter, the number of times of cleaning the container type filter (2) can be reduced.

[0007]

As described above, the present invention continuously separates the angle rotor type centrifugal separator, and the jet guide pipe (1) guides the central portion of the container type filter (2). Then, the precipitate of the large specific gravity and the purified water of the small specific gravity are separated without being mixed with each other. Further, since the container type filter (2) is removed only by hooking the container shaft (8) on the hooking portion (9), the operation can be restarted only by changing the container type filter (2). Therefore, the time for stopping the motor (5) can be shortened by preparing a spare container-shaped filter (2).
