DD224343A1 - DEVICE FOR REMOVING A LUMENFUELLER FROM HOLLOW FIBERS - Google Patents

Abstract

The invention relates to a device for removing a Lumenfuellers of hollow fibers, the z. B. be used in detoxification systems and from which for physiological reasons the production-related therein liquid, coagulationinerten Lumenfueller must be eliminated. With the invention, the elimination of Lumenfuellern should be made economically favorable and with a good quality result in such a way that the once initiated cleaning process does not have to be interrupted. This is achieved by radiomotive to the rotor needle of a centrifuge, at equal angles to each other, running with their ideal Laengsachsen the rotor needle several working chambers, each with a cleaning chamber, at least one input and one output and at least two connected to the input and the output and the cleaning chamber Valves are arranged, wherein the hollow fibers to be processed, either gebuendelt or on rollers, find in the cleaning chambers recording.

Description

Device; for removing a hollow fiber lumen filler International Patent Classification: D 01 F Field of the Invention:

The invention relates to a device for removing a lumen filler made of hollow fibers. "For physiological reasons, it is necessary to eliminate the liquid, coagulation-inert lumen filler contained in the hollow fibers by way of production.

Characteristic of the known technical solutions:

From the industrial practice, where there are no publications, a device is known which consists of the modified rotor of a centrifuge · The rotor is equipped with several places for the storage and attachment of fiber bundles, from which the lumen filler located therein is removed by centrifugation. A disadvantage of this device is that with her only a coarse removal of the chemical is possible, but not one

A Uli

adequate cleaning for the use of the fiber bundle in human medicine. The hollow fiber bundles must be supplied after removal from the centrifuge a rinsing device and a drying station, which requires a relatively high effort.

Object of the invention:

The invention relates to a device with which the removal of the lumen filler from hollow fibers can be carried out more economically and with better quality results than hitherto.

Explanation of the essence of the invention:

The invention had for its object to provide a device for removing a lumen filler made of hollow fibers, with all the operations required to clean the hollow fibers operations are sequentially and without interruption feasible,

According to the invention the object is achieved in that the rotor needle of a known centrifuge radially at equal angles to each other, with their ideelen longitudinal axes perpendicular or slightly inclined to the rotor needle extending, several working chambers, each with a. Cleaning chamber, at least one input and an output and 'at least two connected to the input and the output and the cleaning chamber valves are arranged, wherein the first valve connected on the one hand to the input of the working chamber, on the other hand in the region of at least one end of the cleaning chamber and a multi-way valve and the second valve is connected on the one hand to one end of the cleaning chamber, on the other hand at the outlet of the working chamber «In the cleaning chambers

holding devices are arranged, the holding plates, which cover the entire end faces 18 of the hollow fiber bundles, are constructed as frit bodies interspersed with pores.

Reference to a drawing to an exemplary embodiment, the invention will be explained in more detail · In the drawing:

3 ig # 1 The device in plan view with a working chamber shown in section

Fig. 2 is a side view of a working chamber in section

On the rotor 1 of a centrifuge, not shown in detail, angles of «C = 4-5 ° to each other radially and with their ideelen longitudinal axis 2 perpendicular to the longitudinal axis 3 of the rotor 1 working chambers 4 are arranged. Within the working chamber 4 there is a cleaning chamber 3 " which is provided for receiving the hollow fiber bundle 6 to be cleaned. * The cleaning chamber 3 is equipped with the holding device 7, whose holding plates 8" are formed as circular reamer bodies interspersed with pores 9. In the lower level of FIG Cleaning chamber 3 are bearing shells 10 are fixed, in which the both sides of the hollow fiber bundle 6 outstanding core rod 11 is inserted »The scavenger line 12 coming from the detergent dispenser, not shown, leads to the input 13 of the working chamber 4. Between the input 13 and the cleaning chamber 3 is the first Valve 14, between the cleaning chamber 3 and the outlet 15 of the working chamber 4, the second valve 16 is connected · From the outlet Λ3 , a line 17 leads to a rinsing agent, not shown, the apparatus.

After the hollow fiber bundle 6 is inserted with its core rod 11 in the bearing shells 10 and the end faces of the hollow fiber bundle 6 covered with the holding plates 8 and in known

The cleaning chamber 5 is closed in a liquid-tight manner by means of its lid, which is not shown in more detail.

During start-up and operation of the centrifuge, the first valve 14 is closed, the second valve 16 is opened. The lumen filler located in the hollow fibers is ejected and flows through the frit body 8, the second valve 16 and the line 17 to the treatment plant. After a centrifugation time of about 60 minutes, the second valve 16 is closed and the first valve 14 is opened. The rinsing agent coming from the rinsing agent line 12 penetrates via the inlet 13, the first valve 14 and the frit body 8 into the hollow fibers and into the cavities located between the hollow fibers and dissolves the remnants of the lumen filler, so that a mixture of the two arises. Tray ca · 5 minutes, the second valve 16 is opened, so that this mixture is thrown out and also enters the processing plant. Through the opened first valve 14, washing-up liquid continues to flow into the hollow-fiber bundle 6 for 20 minutes and immediately out of it at the other end, thereby achieving a fine cleaning. Thereafter, the first valve 14 is shut off. In this state, the device is operated for a further thirty minutes while supplying a drying gas for drying the bundles, in order then to come to a standstill. After a further period of time of thirty minutes, the hollow fiber bundles, completely cleaned and dried, are removed for use.
