Description

The invention describes a cleaning device on a water-loaded guide rod, in the form of a straight spray bar, with multiple arranged comb elements and multiple arranged water outlet openings, for cleaning filter inserts, in particular non-pivoting filter brush bodies mounted on a frame, in filter chambers of pond systems and circulation systems of aquaculture.

This type of filter brush inserts are used in water treatment basins or filter chambers to take up dirt particles from holding water, preferably from fish farming systems. These filter inserts are made up of fine-thread brush bodies that are vertically lined up several times in a filter chamber or are permanently installed and interlocking in a frame and are inserted vertically as a flat filter element in a filter chamber. The required regular cleaning of these filter brush inserts is usually carried out directly in the emptied filter chamber or after removing the entire filter brush insert, by rinsing with a water jet or by showering with a hand shower as in the DE 199 41 573 A1 and DE 11 2012 005 155 T5 shown.

With this cleaning method, the problem arises that, due to the close arrangement and fixed installation of the brush bodies in a frame, the brush bodies cannot be pivoted, and so internal contamination cannot be detected with a hand shower. In order to loosen stuck and long-fiber dirt particles, additional auxiliary equipment as well as high spray pressure and water consumption are required. Areas of the filter chamber floor and below the filter brush inserts are difficult to access by means of a hand shower, which makes cleaning the chamber floor more difficult or makes it necessary to remove the filter elements, which is time-consuming.

From the DE 20 2019 104 448 U1 A cleaning device for cleaning filter brushes is known, wherein an annular spray head with comb rods surrounds the brush body and initiates spray jets. The spray head is positioned over the brush body during cleaning and inserted through a ring opening in the center of the brush. Extensive cleaning of the brush body is carried out by moving the spray head up and down using guide rods.

The problem with this cleaning method is that the spray head diameter must be matched to the cylindrical brush body. If the size ratio of the spray head and brush diameter is unsuitable, increased effort is required during the cleaning process or the cleaning result is insufficient due to insufficient engagement of the comb bars. As a result, spray heads of different sizes have to be kept available and the costs per component increase. In the case of filter brush inserts with interlocking, non-pivoting brush bodies that are permanently installed in a frame, interlocked bristles prevent the spray head from sliding through between the brush bodies.

The task is to present a cleaning device that can be manufactured at low cost for flexible use on different installation variants of filter brushes, which, from the point of view of efficiency, shows a clear improvement over the stated prior art. This object is achieved according to the invention in claim 1.

The technical solution provides for a straight spray bar with multiple spray openings and comb elements. The bar body and comb elements are designed as hollow bodies and have a central inlet point for pressurized rinse water, the inlet point for rinse water on the spray bar being located in the center above and the receptacle for a manually operated guide rod with pressurized water supply.

The free mobility of the spray bar during the cleaning process by means of guide rods enables the individual adjustment of contact pressure and effort to the filter medium to be cleaned. The ability to perform lateral movements in addition to vertical up and down movements allows for quick changes of direction and position during cleaning and thus enables effective and time-saving work.

The length of the spray bar and the number of comb elements can be freely designed and has no connection with the dimensioning of the brush bodies used or the installation situation. This enables the use of the component in many ways and inexpensive manufacturing conditions.

The filter brush inserts are cleaned by moving the spray bar loaded with rinsing water by means of guide rods along the brush surface, with the comb elements arranged several times engaging the bristle structure of the brush body. The strip body and the underside of the comb elements have obliquely downwardly directed multiple spray openings, whereby obliquely downwardly directed spray jets are introduced into the bristles of the brush bodies. Stored Dirt particles are rinsed out of the brush bodies towards the filter chamber floor and sediment deposits are rinsed off the chamber floor. The guide rod is advantageously equipped with a telescopic extension, which enables comfortable processing of long filter brush elements in deep filter chambers. The guide rod advantageously has a metering device to regulate the water supply and water pressure, with which the flushing water requirement can be effectively adapted to the cleaning procedure and thus enables water-saving work.

The comb elements, which are arranged several times, have a conical shape and are used to loosen stubborn dirt and remove coarse and fibrous dirt particles. The conical shape reduces the accumulation of dirt particles on the comb elements, in particular of fibrous dirt particles e.g. thread algae, whereby the comb elements have spray openings on the upper attachment, whereby spray jets are directed at the same cone angle along the top of the comb elements. Picked up dirt particles are sprayed off by the comb elements and thus represent a self-cleaning function of the cleaning device.

In order to direct deposits and dirt particles that have already been rinsed out on the filter chamber floor in the direction of a disposal opening, the spray bar has spray openings on the underside which are directed obliquely forwards. During the cleaning process, when the spray bar approaches the chamber floor surface, the dirt load is driven forward under the filter brush inserts. The removal of the filter brush inserts and subsequent cleaning of the chamber floor can thus be saved.

A variant according to claims 1 to 9 is the mirrored arrangement of the comb elements on the opposite side of the spray bar. In this way, filter brush inserts used one after the other can be processed simultaneously and the time required for the cleaning procedure can be reduced even further.

The spray bar is in use 1 on a guide rod 2 mounted with water supply, with the centrally arranged receptacle 5a , the discharge point 5b for pressurized water in the spray bar 1 represents. The one on the inguinal body 1 applied support ribs 7th stabilize the inguinal body 1 by force applied during handling. The cleaning device is used after connecting it to a pressurized water line at the water connection 4th . The cleaning of the filter brush insert 12 takes place in the installed state, in a preferably emptied filter chamber.

The spray bar 1 is used during the cleaning process of the filter brush insert 12 in an up / down movement and sideways movement over the surfaces of the brush bodies 11 guided by actuating the dispensing gun 3 pressurized flushing water through the guide rod 2 to the spray bar 1 is directed. The comb elements 6th penetrate the bristle structure of the brush body 11 a, whereby stuck and clinging fibrous dirt particles are loosened. Through several times on the last body 1 arranged, obliquely downwardly directed spray openings 9a spray jets hit the filter medium and those under the comb elements 6th spray openings pointing downwards at an angle 8th direct spray jets into the brush body 11 inside. By moving the spray bar 6th by means of guide rods 2 dirt particles are removed from the filter brush insert 12 flushed down to the chamber floor (not shown). From the comb elements 6th Any dirt fibers that have been picked up are removed by means of the spray openings arranged at the base of the comb 9b rinsed off so that there is no dirt load on the comb elements 6th can accumulate.

The spray bar approaches during the cleaning process 1 the bottom surface of the filter chamber, sediment deposits and dirt particles that have already been rinsed out are deposited on the underside of the spray bar 1 Spray openings pointing forward at an angle 10 , under the filter brush inserts 12 through, in the working direction with advanced. The filter chamber advantageously has a floor drain for the disposal of cleaned dirt.

6th shows the variant of the spray bar 1 with mirrored arranged comb elements 6th , with which one behind the other arranged filter brush inserts 12 can be edited at the same time. The procedure is the same as before.
