Abstract

PROBLEM TO BE SOLVED: To enhance performance on the whole by improving both a separating function of a high-performance centrifugal separator for solid-liquid separation of mixed liquid of fine particles as an object and a discharging function of the fine particles settled in a separation tank. SOLUTION: The high-performance centrifugal separator for fine particles is constituted of a synchronous rotation mechanism, in which synchronous rotation plates 10 are provided in forced precipitation plates 3 of the inside of a separation tank in order to synchronize separation object liquid in the separation tank 2 supplied from a hollow rotary shaft 1 with the same tank till the same rotation. Further, the centrifugal separator for fine particles is constituted of a magnetic discharge mechanism, in which separated settled fine particles in the separation tank are settled on a rectangular vibration thin plate 7 holding a vibrating magnet 6 in the convex position of the inner wall of the separation tank. A magnetic discharge device 9 holding a fixed magnet 8 homopolarly opposed to the vibrating magnet is equipped. When the fixed magnet of the same device is retreated during operation and approached to the separation tank at time of stopping operation, the vibrating magnet is repulsed and the vibration thin plate is vibrated and the settled fine particles are discarded to the outside of the separation tank as a condensate together with residual liquid.

Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD OF THE INVENTION

[0001] The present invention provides an overall improvement by improving the separation function of a high-performance centrifugal separator for solid-liquid separation for a mixed liquid of fine particles and the function of discharging fine particles (as a concentrated liquid) accumulated in a separation tank. The goal is to achieve higher performance.

[Prior art]

In the conventional high-performance fine particle centrifuge, the separation tank rotating at high speed and the target liquid in the tank do not rotate synchronously due to inertia, and the target liquid tends to rotate at a lower speed than the separation tank. I have. In addition, the function of peeling and discharging solid fine particles deposited on the inner wall of the separation tank is also based on a passive technique, and at present the functionality is extremely low.

[Problems to be solved by the invention]

[0003] The present invention provides a technical solution mechanism for synchronizing rotation of a separation tank of a conventional high-performance fine particle separator and non-synchronous rotation of a target liquid in the separation tank, and a method of removing fine solid particles deposited on the inner wall of the separation tank. The purpose of the present invention is to improve the overall performance of the centrifuge constituted by the technical improvement by the technical discharge mechanism.

[Means for solving the problem]

[0004] The function of synchronizing the rotation of the target liquid in the separation tank is added to the rotation of the separation tank of the centrifugal separator to enhance the separation performance, and the solid particles deposited on the inner wall of the separation tank are separated and discharged. As a technical improvement of the function, an attempt is made to improve the overall performance by a forced vibration mechanism of a repulsion structure by a magnetic force incorporating a strong permanent magnet.

BEST MODE FOR CARRYING OUT THE INVENTION

According to the present invention, there is provided a tuning rotary mechanism having a structure in which several tuning rotary plates are provided in the tank in a vertical direction in order to synchronize the target liquid in the tank with the rotation of the separation tank. And the solid-liquid separation function is improved.

In addition, a strong magnet fixed to the middle and high positions of a plurality of tangle-shaped vibrating thin plates that are in contact with the inner wall inside the tank and that stand upright from the bottom is used to prevent inertia operation when operation is stopped from outside the tank. Vibration is applied to the vibrating thin plate in a structure in which an external magnet opposing the same pole is approached, the fine solid particles deposited on the vibrating plate are separated, and the magnetic force discharge mechanism that flows downward as a concentrated solution has a double effect. Performance is enhanced.

【Example】

The present invention will be described with reference to the drawings. The invention is supported by the upper and lower bearings of a fine particle centrifuge,
The purpose of the present invention is to improve the overall performance by technically improving the internal and external structures of the separation tank (2) fixed to the hollow rotary shaft (1) rotated by the direct-coupled motor (M).

The process of separating and discharging the liquid to be separated into a purified liquid and a fine particle concentrated liquid will be described. When the liquid to be separated (solid arrow in the drawing) is supplied from above the rotating hollow rotary shaft (1), a coaxial horizontal hole The liquid is discharged into the separation tank (2), passes through several forced sedimentation plates (3) and becomes a purified liquid (dotted arrow). The purified liquid integrating device (4) is discharged from the discharge hole at the top of the separation tank (2). As a result, a structure for discharging from the discharge hole of the main body (5) is configured.

The target liquid does not rotate synchronously with the rotating separation tank (2) due to inertia in the rotating separation tank (2), but rather rotates at a relatively low speed. The centrifugal action on the target liquid is reduced and the separation capacity is reduced. Therefore, the structure is such that the solid-liquid separation function is improved by using a forced rotating plate (3) and a synchronous rotating mechanism equipped with several synchronous rotating plates (10).

On the other hand, at the same time as the target liquid is purified by the centrifugal separation action while being upstream, the separated fine particles are inscribed in the entire inner wall of the separation tank (2), stand upright from the bottom of the tank, and are set at the middle and high positions. (6) is piled up on a tangle-shaped vibrating thin plate (7).

The main body (5) is provided with a magnetic force discharging device (9) having a fixed magnet (8) having the same polarity as that of the vibrating magnet (6). ), But when the operation is stopped, the magnetic force discharging device (9) is operated during inertial rotation of the separation tank (2) to fix the fixed magnet (8) close to the separation tank (2). The vibrating magnet (6) continuously repels and vibrates the vibrating thin plate (7) to separate the accumulated fine particles, and the concentrated liquid (double solid arrow) mixed with the residual liquid in the tank drops at the end of rotation, It constitutes a structure that discharges from a waste hole at the bottom of the separation tank (2).

【The invention's effect】

It is believed that the present invention further enhances the performance of fine particle high-performance centrifuges by improving both the separation and discharge functions.
