Sieve collector for collecting rainwater

The invention describes a device that is easy to manufacture for collecting sieved rainwater.

The sieves used in so-called sieve collectors are constantly flowed through on one side (in contrast to the so-called cleaning switch, where the sieve is self-cleaning by backwashing), which means that the sieve used becomes clogged with dirt over time.

In the sieve collectors known today, the sieve cannot be replaced for the purpose of replacement (e.g. different mesh sizes) or cleaning without removing the entire device from the downpipe.

According to the invention, a filter collector with the following features is described:

• Structure made of simple basic bodies, which allows production by plastic injection molding.

• Use of a sieve across the downpipe by inserting a cylindrical sieve body.

• Free flow in the downpipe is guaranteed even when the sieve is blocked.

Function:

The filter collector consists of a housing casing (1), a sieve body (3,4) inserted transversely into this casing and a guide body (2). The guide body (2) can be part of the casing (1). The upwardly opening pipe (3) that holds the sieve (4) can be firmly integrated into the casing so that only the sieve (4) can be pulled out after removing the end cap/plug (5), or the pipe (3) and sieve (4) can form a unit.

The water flowing into the collector from above is guided through the guide surfaces of the guide body (2) onto the sieve body (3,4). Depending on the mesh size of the sieve, the upward-facing sieve surface allows purified water to flow into the sieve body, which is closed at the bottom. The water that has penetrated into the sieve body is guided via the connection (6) e.g. into a rain barrel.

Figure 1 shows an example of a realization of the filter collector.

Claims (4)

Applicant Reinhold Holstein Theodor-Heuss-Str. 33 89547 Gerstetten Claims 1. Filter collector for rainwater purification characterized in that a sieve body (3, 4) is installed in a housing (1) into which the rainwater flows from above, transversely to the flow direction in the downpipe, in such a way that the sieve body can be completely or partially pulled out of the housing (1) laterally or, after removing the pipe closure (5), only the sieve (4) can be pulled out of the pipe (3), and the rainwater flowing into the filter collector from above is guided to the filter body by means of guide surfaces (7), and the sieve body only narrows the cross-section of the housing (1) to such an extent that water can still flow past on both sides of the sieve body, and the sieve body is completely or partially closed on the underside, whereby the water flowing through the sieve (4) into the pipe (3) can only flow out via the connection (6) if the pipe (5) is closed on one side, or from two connections if the pipe is open on both sides. 2. Filter collector according to claim 1 characterized in that the guide surfaces (7) can be part of a so-called guide body (2) which is inserted into the housing (1) from above. 3. Filter collector according to claim 1 and 2 characterized in that the filter body (3,4) can have any cross-sectional profile (e.g. round, oval, square) and the tube (3) and sieve (4) can form a unit. 4. Filter collector according to claim I to 3 characterized in that the connection 6 can be part of the pipe (3), or the filter body can be inserted into the connection (6), or the filter body can be plugged onto the connection (6) that is led into the housing (1).
