Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a cone-type continuous centrifuge used for solid-liquid separation treatment in the chemical industry, pharmaceutical industry, food industry and the like.

[Conventional technology]

In recent years, solid-liquid separation processes in various industries, for example,
The cone type continuous centrifuge disclosed in Japanese Patent No. 8756 is widely used.

By the way, as shown in Fig. 3, the basket of this cone type continuous centrifuge is designed to rotate at high speed.
It is mounted on 11 and is firmly fixed by basket retainer nut 12. The screen 2 attached to the inner peripheral surface of the cone of the basket is usually removed by removing the conical ball 6, the screw nut 5, the screw 3, and the screen retainer 7.

[Problems to be solved by the device]

The cone type continuous centrifuge is a machine that operates continuously,
Due to long-term operation, the screen 2 may be distorted, or the liquid drainage groove 4 of the basket may be difficult to be inserted, so that the screen cannot be removed only by the above means.

In addition, the long-time operation causes the fine particle cake to gradually adhere to the outer peripheral surface of the screen and the inner peripheral surface of the basket, and it becomes necessary to wash and remove the adhered fine particle cake after the operation for a predetermined time.

In such a case, it cannot be removed simply by removing the screen, and the basket must be removed and cleaned frequently. Since this removal, cleaning, and re-removal work requires time and labor, the cone-type continuous centrifuge cannot be used during that time, reducing the operating rate of the machine and greatly affecting the solid-liquid separation processing work. give. In particular, in the case of a processed product with which the basket and screen are frequently cleaned and replaced, or a processed product requiring hygiene, cleaning of the basket and screen has become a major issue.

An object of the present invention is to provide a basket of a cone type continuous centrifuge capable of improving the operation rate of a machine by enabling cleaning and replacement of the basket and the screen quickly and easily. .

[Means for Solving the Problems]

In order to achieve the above object, the basket of the cone-type continuous centrifugal separator of the present invention is equipped with a screen on the inner peripheral surface thereof, and an inner basket having a drainage groove is provided. The gist of the present invention is that the outer basket having the drainage holes fixed to is abutted and supported so as to be detachably arranged in the outer basket.

〔Example〕

 Hereinafter, the present invention will be described based on an embodiment shown in the drawings.

The outer basket 10 of the cone-type continuous centrifuge has a predetermined cone-shape depending on its capacity, and the outer surface of the outer basket 10 has a constant inclination angle with respect to the horizontal axis of the separator. (About 20 degrees), it is mounted on the basket shaft 11 of the centrifuge body so as to rotate at high speed, and is firmly fixed by the basket pressing nut 12.

The cone-shaped outer basket 10 has a screen 2 on the inner peripheral surface.
The inner basket 1 equipped with is detachably arranged, the screw 3 is detachably arranged inside thereof, and the liquid supply / washing pipe 8 is further arranged inside thereof.

At the tip of the outer cone type basket 10, a conical ball 6 is detachably arranged.

The outer peripheral surface of the inner basket 1 is formed into a conical taper shape along the conical tapered inner peripheral surface of the outer basket 10, and the base thereof is fitted into the outer basket 10 to form the outer basket 10.
The outer basket 10 is abutted against and supported by the base of the
It is fixed by abutting and supporting the tip of the.

The inner basket 1 with the screen 2 attached in this way
Are fixed to the outer basket 10 and integrally rotated at high speed by the basket shaft 11.

A large number of drainage grooves 4 are formed on the peripheral surface of the inner basket 1 and a large number of drainage holes 13 are formed on the peripheral surface of the outer basket 10. In this case, as shown in FIG. The hole diameter of is larger than that of the drainage groove 4.

When the inner basket 1 and the screen 2 need to be cleaned, the liquid supply / cleaning pipe 8 is moved from inside the inner basket 1, and the conical ball 6, the screw nut 5,
By removing the screw 3 and the screen retainer 7, the inner basket 1 can be quickly and easily removed together with the screen 2. At this time, since the liquid removal holes 13 formed on the peripheral surface of the outer basket 10 are formed large, the fine particles adhering to the outer basket 10 can be removed by washing with the outer basket 10 mounted on the basket shaft 11. The cake can be removed.

The removed inner basket 1 and screen 2 are washed outside the machine and then attached again. It should be noted that the availability of the machine can be further improved by attaching a spare inner basket and a screen prepared in advance.

[Effect of device]

According to the present invention, by removably disposing the inner basket and the screen on the outer basket, the inner basket and the screen can be removed from the outer basket, and cleaning and replacement can be performed quickly and easily. The operating rate can be improved. Moreover, since the base and the tip of the inner basket having the screen attached to the inner peripheral surface are brought into contact with and supported by the outer basket, the inner basket can be attached to the outer basket in a stable and well-balanced manner. It is possible to stably drive the cone-type continuous centrifugal separator in which the basket rotates at high speed.
