Abstract

The device 1 consists of 2 modules with a modular structure, characterized in that the device can be selected for UVC disinfection either alone or with an optional extension, depending on the requirements for filtration and pollutant reduction.

Description

The invention relates to a device 1 for attachment to a downpipe filter ( 1 ) which is used as RW collector in the building roof drainage.

The device consists of two modules.

The first assembly provides the granular filter ( 2 ) with rinsing device ( 5 ), the second group UVC disinfection ( 3 ) with the associated control unit ( 4 ) with float switch as sensor element for UVC sterilization.

A junction box with terminal strip and a Schuko socket ( 6 ) are also mounted on the mounting plate.

Both units ( 2 . 5 ) and ( 3 . 4 . 6 ) can be used in combination or separately. Dismantling during the winter months is not required as the device 1 a forced emptying that prevents freezing.

GRANU-filtration

According to the current state of the art, there is this known downpipe filter ( 1 ) which has the task to separate the impurities of water from leaves, moss, and insects and various pollutions.

Due to the integrated filter insert in the downpipe collector, more or less impurities are screened out, which in turn depends on the fineness d. H. Mesh size of the filter insert is dependent.

A disadvantage is found that with a small mesh size (0.2-0.3 mm) after a certain time a blending of the filter element's occurs and this state is not detectable by the opacity of the filter body externally and without disassembly of the downcomer.

The device described above 1 sets right there to the water inlet from the downpipe filter ( 1 ) to minimize the suspended matter and any pollutants that may be present to ensure a good filtration and thus a high rainwater quality.

According to the invention this is achieved by a granular filter system 2 is used, with a granulate mixture, which ensures that the prefiltered rainwater (MW 0.4 mm) nachfiltriert, various pollutants bound by appropriate material and thus detoxified.

In combination with a connection of the UVC sterilization 3 a good quality of rainwater is achieved.

The granulate filter system 2 consisting of a transparent tubular body ( 1 ) horizontally in the middle through a transparent partition ( 2 ) is shared. From below, the transparent tubular body ( 1 ) by inserting a so-called reversal chamber ( 6 ) locked.

The transparent tubular body ( 1 ) has an inlet, - and outlet nozzle ( 3 . 4 ) in both nozzles are in the inner region of the tubular body ( 1 ) vertical and horizontal openings ( 10 ) appropriate.

In inlet connection ( 3 ) are two offset to each other so-called thresholds ( 5 Attached, thereby a calmed inlet is achieved, at the same time the suspended matter is retained and via a flexible connecting line ( 7 ) to the reversing chamber ( 6 ) discharged (forced discharge).

Within the transparent tubular body ( 1 ) are the inlet, - and outlet nozzle ( 3 . 4 ) with a coarse-mesh sieve ( 14 ), this in turn prevents flooding of the granules in the nozzle.

In the bottom of the transparent tubular body ( 1 ) inserted reversing chamber ( 6 ) has the task of the bottom of the tubular body ( 1 ) and thus simultaneously within the tubular body ( 1 ) 3 cavities to create.

The cavity (A) serves to receive the corresponding coarse granules.

The cavity (B) serves to receive the correspondingly fine granules.

The granules can be introduced in bulk or in bound form.

The third cavity (C) is achieved with the inventively designed reversing chamber.

The reversing chamber ( 6 ) is a round disc which is reduced by a wide groove in diameter by a corresponding amount. As a result, you form two narrow webs (D, E) called tube sheets.

In the upper bridge (D) holes are provided, in the right side larger holes and in the left side smaller holes.

So that the inserted reversing chamber ( 6 ) tightly with the transparent tubular body ( 1 ) can be closed, are appropriate O-rings ( 8th ) used.

In the middle of the reversing chamber ( 6 ) is provided an opening. Through the opening ( 15 ), the suspended solids can be transported via a flexible 9 ) are discharged to the downpipe.

For the flushing process 5 can the flexible line ( 9 ) with the connecting piece ( 9.1 ) completely removed.

This frees up a larger opening downwards, so that the dirty rinse water can flow off faster and optimize the cleaning effect.

The device 1 is suitable for winter operation and forms the basis for a maintenance-free system with forced discharge.

In the partition ( 2 ) 2 of the tubular body ( 1 ), is a vertical longitudinal slot in this a transparent guide tube ( 11 ) with a red ball ( 11 ) is attached.

This increases or decreases, depending on whether much or less water is running. Thus, the operating state of the device can be checked (level display).

During normal operation, depending on the water supply, the ball will rise in a safe working area.

If the ball rises disproportionately, this is a sign that the filter has clogged up. This can be eliminated by rinsing or by replacing the granules.

A rinse can the built-in rinsing device 5 be made.

Through the attached ring distributor ( 1 ) 5 is the rinse water over the 4 connected nozzles ( 2 ) distributed within the granule filter.

For the cavity (A) and (B) 5 are each 2 nozzle sticks ( 2 ) introduced vertically.

Each of the nozzle blocks is the same design, consisting of a tubular body ( 2 ) in the lower area and at the bottom are small holes ( 3 ).

These have the task of directing the rinse water in the appropriate direction (R) and inject it into the granulate chamber.

Through the connecting lines ( 5 ), the 4 nozzle sticks with the ring distributor ( 1 ) connected. The ring distributor ( 1 ) with a horizontally arranged threaded connector ( 6 ). About this nozzle, the supply of water or air can be connected as flushing medium.

Before the start of rinsing, the bottom of the granulate filter 2 flexible line ( 9 ) and the sealing plug ( 9.1 ) are removed. Thus, a larger opening is free, so that the dirt can be rinsed out.

In addition, it is ensured that when the highest water level is reached, the surplus water is returned to the downpipe filter via the on-site selected horizontal Abstandmaß (height assembly of the device to the downpipe filter) and discharged through the downpipe.

Will the granular filter 2 used as a solo assembly, so is on the outlet nozzle ( 4 ) a 90 ° elbow ( 12 ) fitted with a viewing window ( 13 ) is executed.

This window is used to view the filtered water inlet to the storage tank and thus also to check the function of the granulate filter 2 ,

In the area of the transparent tubular body ( 1 ) 2 is a transparent bow shield ( 17 ) with an integrated LED light ( 18 ) on the mounting plate ( 16 ) appropriate.

The luminaire offers a functional check of the granulate filter at night 2 , it is powered by a small solar cell and can be turned on when needed.

At the same time, the upwardly open tubular body ( 1 ) covered by the shield.

The 3 shows a UVC sterilization, consists of a tubular body ( 1 ) of an inlet nozzle ( 2 ) and an outlet with 90 ° elbow ( 3 ).

The pipe has a closed bottom ( 4 ).

In the lower part of the pipe is a bottom opening ( 5 ) provided with a flexible connecting line ( 6 ) with the drain neck ( 3 This in turn is required for winter operation and thus can be the complete device 1 idle in the cold season.

The tubular body ( 1 ) 3 is on top with a screw-on lid ( 7 ) locked.

In the middle of the lid ( 7 ) is an elongated quartz glass tube ( 8th ) with inserted UVC radiation source ( 9 ) assembled.

The UVC radiation source is powered by an electrical 10 ) and the attached plug with integrated transformer are powered.
