Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a centrifugal separator consisting of a cylindrical rotating tube elongated in the vertical axis direction.

This type of centrifugal separator is known as a so-called Sharpless ultracentrifuge, and is widely used in industrial fields requiring separation operations, and has a long history.

One common conventional device of this type, as shown in FIG. It consists of a cylindrical rotating tube 3 in the direction.

Attach the drive plate 4 to the top of the pedestal,
A bearing assembly Y-7 is attached to the other end of the -iK motor 5 of this drive plate, and a belt 8 connects the motor pulley 6 and the bearing pulley 18.

A spindle 9 is provided at the center of this bearing assembly, and the spindle and the top end of the rotating cylinder 3 are screwed together with a coupling nut 10.
The rotary cylinder 6 is in a suspended state, and the screwed together spindle and the top tip of the rotary cylinder are covered by a spindle shield 17 and a housing 56. In addition, the bottom of the rotary cylinder 3 is in contact with a bushing 12 provided at the lower part of the casing 1, and when the rotary cylinder rotates, there is a drag.
) to prevent eccentricity.

In addition, the drive plate 4 is integrated with the pedestal 2, that is, it is a part of the pedestal structure, and the motor 5 is placed directly above the rotating cylinder 3 without using the motor pulley 6, bearing pulley 18, and belt 8. There is also a type that is directly attached and the motor shaft and spindle are directly interlocked via the bearing assembly 7.

These devices also include a fluid supply port 13, a fluid drain port 14 that connects to a centripetal pump (not shown), a cover assembly 15, and a hand nut that secures the centripetal pump at the top of the seven-piece assembly. 16 etc. are attached, and may also include other members as necessary, such as a cooling coil provided in the space between the casing 1 and the rotating cylinder 3, although not shown.

When operating a centrifugal separator, it is usually used for cleaning purposes or after the separation process. In order to take out the large separated material, it is necessary to take the rotating cylinder in and out of the casing.〇This work can be done by unscrewing the coupling nut from the top of the rotating cylinder and then moving the drive plate sideways. If the drive plate is integrated with the pedestal, the casing should be shaped like an inverted truncated cone with a wider cross-section at the top, and the rotating cylinder should be lifted up using a lifting machine or the like, or if the drive plate is integrated with the pedestal, It was necessary to provide some space in the dimensions so that it could be removed from below inside the unscrewed rotary cylinder casing, and to raise the rotary cylinder somewhat obliquely. Such work is complicated, and lifting of stacked objects is dangerous and requires caution.

Moreover, in order to lift or pull up the rotating cylinder, a ceiling height equal to the sum of the length of the rotating cylinder in the axial direction above the top of the casing, that is, a ceiling height that is at least twice the length of the rotating cylinder is required. do.

Therefore, when installing a new centrifugal separator of this type in an existing work room with limited ceiling height, the capacity of the device will be limited due to the height.
Sterile rooms, clean rooms, and safety rooms installed in bio-related fields are generally compact and have space constraints, which prevents the installation of centrifugal separators of the desired capacity in second-class equipment rooms. This caused a drawback.

The present invention solves these drawbacks and develops a device that allows a centrifugal separator with the desired capacity to be installed in a limited space, and also allows for easy and safe loading and unloading of the rotating cylinder. This made it possible to install a centrifugal separator with a height that is almost the same as the ceiling height in a room with a limited ceiling height.

According to the present invention, the casing, which was conventionally fixed or integrated with the pedestal, can be rolled over or tilted to a horizontal position with respect to the vertical axis of the pedestal, thereby releasing the casing from the spindle. To provide a centrifugal separator in which a rotating cylinder can be horizontally taken in and out from a casing. Hereinafter, the present invention will be explained in detail based on embodiments (with reference to drawings).

The centrifugal separator of the present invention, as shown in FIGS. 6 to 4,
This summer device differs from the conventional summer device shown in FIG. 1 in that the casing 1 has a cylindrical shaft member 20 integrated or fixed to the side surface on the pedestal side. That is, as shown in FIGS. 3 and 4, the shaft member is inserted into an opening provided at an appropriate portion of the pedestal 2, passes through the pedestal, and then passes through the bearing means 25 and 2 provided at both ends of the pedestal opening. ' is rotatably supported. A worm foil 21 is provided at the tip of the shaft member passing through the pedestal, and meshes with a worm 22 held by the pedestal. Each end of the worm is supported by a pole bearing 24, 24', and a handle 25 is attached to one end of the worm. Furthermore, in order to reinforce the support of the casing during operation, the pedestal has a lock bin 27 above the shaft member 20, and crank levers 26 at four locations around the shaft member, above, below, and on the left and right.
It is preferable to provide them so that they can be inserted into receiving holes provided at corresponding positions in the casing 1, respectively. The locking pin 27 is also effective for positioning the casing 1 in its vertical normal position.

The device of the present invention having such a structure enables the casing to be overturned at least horizontally with respect to the pedestal as shown by arrow C in FIG. 5 by the following operation.

First, spindle shield 17 is loosened, pushed upward, and fixed to bearing assembly 7. Next, the coupling nut 10 is loosened to release the threaded connection between the spindle 9 and the rotary cylinder 3. Loosen hand nut 16 and loosen centripetal pump (not shown). After this,
Preferably, the rotating barrel is firmly fixed by the rotating barrel support device 30 so that the rotating barrel does not move when the casing 1 is overturned. As shown in FIG. 6, the rotating cylinder support device 50 is provided with a rotating cylinder support rod 31 housed in a housing 37 installed at an appropriate position on the side of the rollover so as to support the rotating cylinder at the time of rollover on the upper part of the casing 1. This rotary cylinder support rod can be slid and displaced between the position (a) where the rotary cylinder is fixed when the rotary cylinder is taken out and the position (b) where the rotary cylinder is released when the device is operated. It is operated by a handle 32 attached to the outer end of the rotary tube support. As shown in Figure 6-b, the inner tip of the support rod has a structure that can sufficiently support the rotating cylinder. Move the handle 32 of the rotary tube support device 3° to the rotary tube fixing position (a) to support the rotary tube.
The rod 31 is pushed forward, the support rod 31 is pushed into the outer periphery of the rotary cylinder 3, and the support rod is brought into contact with the outer periphery of the rotary cylinder to prevent the rotary cylinder from moving when the casing 1 rolls over.

Next, the casing 1 should be tilted in the direction of arrow C.
If crank lever 26 and lock bin 27 are used, loosen the crank lever and pull out lock bin 27.

Then, rotate the handle 25 to rotate the casing 1 by 90 degrees.
Rotate approximately 90' in the direction of arrow C and remove cover assembly 15.

Next, as shown in FIG. 7, the holder 34 is fitted onto the rotary tube 3 and attached to the outer periphery of the casing 1.

Then, return the handle 32 of the rotary tube support device 3o to the (b) position, and remove the support rod 31 from the rotary tube 3.
pull apart. Thereafter, as shown in FIG. 8, after pushing the rotary tube insertion member 40 made of a soft material such as Teflon into the casing 1, the holder 34 is removed, and the rotary tube 3 is placed on top of the rotary tube insertion member 40. While sliding it, pull it out horizontally.

In addition, as a reverse operation to the above, the rotary cylinder 3 is moved to the casing 1.
When assembling the device by inserting the tube into the tube, the rotating tube can be assembled easily and safely because the procedure is completely opposite to the above.

In this manner, according to the present invention, by placing the casing in a horizontal position, the rotary cylinder can be safely and easily taken out from the casing with a simple operation. Therefore,
A centrifugal separator can be installed in a sterile room or other limited space, especially in a space with limited height, making use of the full height of the space, allowing the desired large capacity device to be installed in a narrow space. It is now possible to set up a

In addition, in the case of conventional machines, the upper drive device is fixed,
In order to make it easier to pull out the rotating cylinder upwards, it was necessary to make the shape of the casing into an inverted truncated cone shape with a large diameter at the top, but according to the present invention, it is possible to have a cylindrical structure that matches the rotating cylinder, No need for extra materials or exclusive use of space than necessary.

Therefore, the functional and economic effects of the device of the present invention are extremely large.
