remove the last impurities from the spin- Of course such filter carning solutions. tridges have to be replaced from time to time by fresh ones. Owing to the changing however a certain amount of still unfiltered solution can very easily pass over on to the clean side and the penetration of air is also not precluded. To make good these two involves loss of time and material.
In order to remove these disadvantages the arrangement has been suggested of inserting in the pipe in a stationary position a plurality of filters in parallel so as to make it possible to work without interrupting the,
flow of liquid. Owing to the employment of numerous cocks however which had to be operated in a definite sequence when changing over, the danger arose of unfiltered solution passing over, of air entering and of the flow of liquid being interrupted. These dangers were further increased by the necessity of changing the filter body. In the case of the filter according to the present invention all this is obviated because the changing over is effected positively and the filters during the cleaning remain in the liquid-filled casing. 1
The filter according to the present invention is characterized by the feature that two or more individual filters are arranged on a movable under-frame in such a wa that by properly displacing the frame the lters can be brought singly into the cleaning position, the working position and the position of rest. In the constructional form of the subjectmatter of the invention described later an arrangement resembling a revolvin head is provided wherein the individual lters are located upon a rotatable base which can be moved in a circle round a stationary central member. The base and the central member are provided with passages in such a way that in a particular position one filter is in the working position while the other filteror filters are either completely disconnected or so connected with the central member that the cleaningrof the filters is effected by the backward flowing or purified liquid.
The details of the invention are given in the following specification:
In the accompanying drawing F g. 1 shows in part diagrammatically in section the general arrangement according to the invention; a
Fig. 2 is in part a section through the stationary central member onthe line A-'B in Fig. 1;
Fig. 3 is partly a plan withthe filter in position on the left hand side and the filter removed on the right hand side and partly a section on the line CD in Fig. 1 through the stationary central member Fi 4 is a view similar to Flg. 1, but with the filters in a different, position relative to the stationary central member;
Fig. 5 is a plan of Fig. 4.
The liquid to be filtered passes through an inlet pipe union b of a branch piece a into a stationary cock plug d, see Fig. 1.' From the bore of the plug the liquid to be filtered passes into a passage 9 of a rotatable cock casing n and then flows into a bellc to a fil ter cartridge From the interior of the filter cartridge 7 the filtered solution passes back through a passage h into the cock casing n and flows on through another bore into the cock plug d which in turn is connected with a second pi e union 6 of the branch piece a, whence tiie purified liquid is transmitted to the place where it is to be used.
. Fig. 1 shows the rotatable casing which is of symmetrical construction on both sides and which also. carries two filter cartridges, with bells. If the filter cartridge f has be come choked a cleaned second filter f can be put in place of the first by simply rotating the cock casing n and consequently the filtering can be carried on almost without interruption.
The cleaning of the filter f is not effected by taking it out but by rinsing it back with fresh filtered solution from the interior of the cartridge outwards whereby the dirt is tapped off out of the bells e, e from the outer side of the cartridges through the ing position,
I mg shown.
cording to Fig. 4 on the right-hand side in which the filter f to be cleaned is only connected with the cock plug d through the fresh liquid passage h. Figs. 4 and 5 accordingly show one filter cartridge f in operation, both passages of the casing and ,also of the plug being for this filter open for filtering, and the second filter f in the cleanthe passage 9 for the unpurified liquid having no corresponding bore and hence being closed so that the rearwardly flowing purified liquid flows away, with the dirt that has been removed, through the. h
right-hand cock Z.
Figs. 1, 2 and 3 also show one cartridge filter in operation, but the other completely shut off by the plug (1. In this position the filter, that is shut ofl' can in exceptional cases be opened.
Thus there serves for the controlling of the filters a five-way plug, the ducts in which correspond to symmetrically arranged double passages in the rotatable casing a.
After the filter has been cleaned, it is advisable to-completely fill the bell surrounding it with liquid in order that the cartridge within the bell may be completely immersed. If air is allowed to remain in the bell, air bubbles will enter the outlet pipe with the liquid conveyed to the spinning nozzle and will cause interruptions and imperfections in the thread. The pipes i and i, which are connected with the interior ofthe bells e and 6' respectively, and which may be provided with suitable valves (not shown), are connected to a suitable suction means (not shown) and when the suction is applied the bell may be completely filled with the liquid which is allowed to flow into it through the inlet conduit 9 of g.
Figs. 3 and 5 show the exchangeable filter in plan, the bores of the cock plug also be- The passage for the impure liquid opens on to two transverse bores (Fig. 3), while the passage of the purified liquid only opens on to three transverse bores in the plug (Fig. 2). Each of the passages is connected with a pressure indicator 1' and r respectively. 0 and p are adjusting rings with screw threads on the plug for making a fluid-tight closure between plug and casing.
The outer bells e and e and also the covers it for closing the filter cylinders are pressed on tight by means of conical screws Z and w andlscrew-threaded spindles m.
