Overflow cylinder as suction nozzle for swimming pools

Suction nozzle of a filter pump for swimming pools, whereby the cylinder is designed to be completely underneath to be immersed in the water level and which cylinder has at least one, preferably parallel to the cylinder axis having arranged suction tube and the cylinder cavity against the suction tube through a filter is separated.

Such üe'o erlauf cylinders are known. They are built completely under water in the swimming pool and, in collaboration with the filter puiape, serve to purify the water. The overflow cylinders stand vertically in the water and usually have a buzzing cover that can be slid up and down on the cylinder and has a central opening. This cover adapts to the height of the water surface.

In known designs, either a sack made of filter paper or fabric is used as a filter in the overflow cylinder * This sack is washed ashore with diatomite, so that it: se forums are tight ·. The insertion and removal of the filter aoke is complicated to use and prone to failure because the sack filled with Y / ater is very heavy. However, the sack must not be damaged · It must fit exactly be executed. ι

The task of the innovation is to improve the filter material and its replacement. To solve this problem is the overflow cylinder of the type mentioned at the beginning

characterized in that the suction tube is cylindrical and that the filter consists of an aiii üieöcö tube au * Eetzbaren filter body consists of an axial cavity for the suction tube, around which cavity a filter paper folded many times in the longitudinal direction is arranged.

In the drawing, an embodiment of the object is shown according to the innovation. Show it

The overflow cylinder consists of the cylinder 4 with a mounted, floating, gleitba- on the cylinder ren lid 5 with a central opening 50. In the cylinder is sich- das.Absaugrohr 6, are placed on which two filter body. 7 At the top, the suction tube is closed with the cap 8, which also serves as a holder for the filter body 7. The suction pipe 5 is preferably arranged centrally in the cylinder 4. In the example shown, its height is chosen so that two filter bodies 7 can be attached. It is also possible for two suction pipes 5, which are spaced parallel to one another, to be arranged, or the drill hole can have the same height as the filter body.

As FIGS. 2 and 3 show, the suction tube 6 consists of a cylindrical socket part, the wall of which is radial has extending bores 60, which are helically adjacent over the entire length of the Rohres are distributed. Above is the ear through the screwed on Cap 8 closed, at the bottom there is the connection sleeve to line 2.

The pilter body 7 is an entirely

exchangeable consumable. It has an inner cylindrical sleeve 9, the inner diameter of which is larger is than the outside diameter of the suction pipe, so that the filter body 7 is placed on the suction pipe 6 with play can be. The sleeve has radially extending bores 90 which, as in the case of the suction pipe, are helical are arranged side by side.

The filter paper 70 is arranged around the central sleeve 9, which is folded like a concertina in the longitudinal direction of the filter body. The filter surfaces run through the fold approximately radial. A large filter is obtained area in a small space.

After removing the cover 5 and the cap S, the filter body (s) 7 can be replaced. These bodies are therefore easy to replace, easy to store and not very sensitive to damage.
