Description

Cleaning device for water

The invention relates to a cleaning device for water according to the preamble of patent claim 1.

Cleaning devices for water, which work on the principle of reverse osmosis, are known in the field of drinking water production for many decades and in the meantime widespread. They are an important tool to produce healthy drinking water. In reverse osmosis, the water to be purified is pressed at high pressure through an ultrafine membrane, the membrane for the pollutants is not or only slightly permeable. In addition to stationary cleaning devices and portable cleaning devices are known.

A portable cleaning device is disclosed, for example, in US 5,788,858. The reverse osmosis unit consists of a plurality of horizontally parallel tubes, which are held by a metal support frame. The pipe material used is generally plastic. To be able to use the cleaning device in different places, the system is mounted on a vehicle.

Another cleaning device for water is known from EP 0 065 070 A2. The disclosed device consists of a meandering tube. The pipe bends are designed around a support frame designed for this purpose. The pipes in the individual layers have a slope in order to be able to empty the system easily.

In order to meet the increasing demand for water, especially in desert regions, more and more large stationary plants for the production of drinking water are being constructed, which have a multiplicity of layers of essentially horizontally parallel tubes and operate on the principle of reverse osmosis.

BESTATIGUNGSKOPIE A disadvantage of the previous solutions is that each adapted to the size of the cleaning devices carrying scaffolds, which generally consist of metal or stainless steel, must be made. The dimensioning of the scaffoldings must be adapted to the local conditions, with the support of the large number of tubes and their large weight, the support racks must have sufficient rigidity or static load capacity, depending on the design of the support frames are for fastening the pipes used different types of intermediate frames or welded elaborately. In this case, the intermediate parts must have a sufficient dimensional stability. In order to adapt the metal bearing, welding processes are mostly used. In addition to the fulfillment of static requirements, the dimensional stability and the requirements and the corrosion resistance, especially in seawater desalination plants are further important prerequisites for reliable operation. Especially when used in corrosive environment often high quality and expensive stainless steel is used.

In addition, the extremely time-consuming construction of the carrying frames except high material costs further high costs, especially in the construction of large plants. Furthermore, because of the demands on the quality and dimensional accuracy of the individual construction error prone and perform only by well-trained professionals such as welders, locksmiths and metal workers.

Against this background, the object of the invention is to provide a cleaning device for water, which reduces the disadvantages of the prior art.

The object is achieved by a cleaning device for water with the features of claim 1. Advantageous embodiments of the invention are the subject of dependent claims.

According to the subject matter of the invention, a cleaning device for water, which works on the principle of reverse osmosis and has a plurality of substantially parallel running tubes, is provided first self-supporting identical parts are provided which have a plurality of recesses for non-positive reception of the tubes and the identical parts are stackable.

An advantage of the cleaning device according to the invention is that it is possible to build up large installations at the place of use very quickly in a cost-effective and simple manner. In particular, the use of first self-supporting identical parts for the first time also large plants for drinking water production without specialist personnel can be easily and reliably established. Furthermore, such first identical parts can be mass-produced inexpensively and can be transported in a space-saving and easy way.

In a further development, two stacked first identical parts form an opening for receiving at least one tube. By the first identical parts each having only a preferably semicircular recess for receiving the tubes, the static load capacity is only slightly affected by the discontinuity of the shape in the first common parts. Furthermore, the introduction of the tubes, whose weight can be several 100 kg, easily and quickly perform by simply lowering. Furthermore, the size of the recess in the manufacture, for example by means of a casting method, by a modification of the moldings used for the production easily adapted to the diameter of the tubes used. Also can be adjusted by inserting fitting pieces in the first common parts or the respective pipe sections and larger recesses easily to smaller pipe diameter later. In addition, it is possible in particular when using düng of elastic materials as fitting pieces, in addition to the positive and a positive connection between the first common parts and the tubes to achieve. As a result, the pipes embedded between the first identical parts can be secured against a translatory displacement.

According to another embodiment, the first identical parts, in particular at their respective top and bottom, on shaped pieces, which at least partially interlock when stacked. Accordingly, can be Align the first identical parts when stacking against each other without any further aids. Further, the first equal parts are secured against slipping sideways, and the rigidity and self-supporting ability of the first common parts and the entire cleaning device are increased.

In another preferred embodiment, the first identical parts can be connected to second identical parts. Furthermore, it is advantageous if, for this purpose, shaped pieces are formed at the head ends of the first identical parts in order to at least partially connect the first identical parts with the second identical parts in a form-fitting manner. Investigations by the applicant have shown that it is advantageous to form the second identical parts as side parts, which preferably also have recesses for weight savings. This makes it possible in a simple manner to provide a module in which the first common parts are used as middle parts and the second identical parts as side parts. Particularly in the case of large systems, the pipe length of a pipe is several meters, and it is therefore preferable to support the pipes at several sections. Accordingly, it is provided in order not to overstress the mostly made of plastic pipes that a module in addition to two side parts preferably has three stacked between the side parts rows of middle parts. By the fittings at the head ends of the first common parts, which is designed, for example dovetailed, and the second identical parts have a corresponding receptacle, it is possible the modules together quickly and dimensionally without further tools on site.

According to another embodiment, it is advantageous to connect the second identical parts by means of fastening means with the first identical parts. Preferred fastening means are, for example, threaded rods, by means of which, in the case of an embodiment of the second identical parts as side parts or in the case of an embodiment of the first identical parts as middle parts, the side parts can be frictionally connected to the parts. In order to ensure rapid assembly, it is advantageous to provide in the first and second identical parts suitable Aussparrungen by which the fastening means can be easily inserted. By using suitable fasteners can be, inter alia significantly increase the stability of the modules. Accordingly, it is also possible to prefabricate entire modules and to transport the individual modules assembled at the place of use and without the usual steel beam constructions, quickly and inexpensively to larger units to connect. Furthermore, the size of the units can be easily varied. Investigations by the applicant have shown that it is advantageous to make the side parts particularly stiff and statically resilient. By the fastening means and their non-positive connection possibility of the middle parts with the side parts, the large bearing forces of the tubes can be at least partially transmitted to the side walls. As a result, it is possible to stack several modules one above the other without unduly burdening the lowermost layer of the underlying module or its first common parts.

In a preferred refinement, third identical parts are provided as spacers which make it possible to predetermine the distance between two opposing second identical parts within a module without the first identical parts already having to be used for this purpose. Preferably, the third identical parts at the respective head ends on shaped pieces, for example in the form of a Schwalbeschwanzausformung on. As a result, the third identical parts can be easily introduced into corresponding formations in the second identical parts. Furthermore, it is possible to form the third identical parts or the spacers as a support body to direct the loads of the resting middle parts on the side walls. It when the spacers is retracted at least below the bottom layer of the first common parts is particularly advantageous. Furthermore, it is advantageous if the spacers are connectable by means of fastening means with the side parts in order to transfer the large weight forces of the overlying tubes in the third common parts.

In a particularly preferred development, the first and / or the second and / or the third identical parts are made of reinforced concrete. Hereby, by means of the reinforcement to be inserted it is easy to adapt all types of identical parts to the required load capacity. Furthermore, the identical parts can be prefabricated and easily transported to the place of use. It is also possible to produce the required equal parts at the place of use. One Another advantage is that the material is almost everywhere available and inexpensive. By using reinforced concrete, a large corrosion resistance can be achieved easily and inexpensively.

In a further development, it is preferable to manufacture the first and / or the second and / or the third identical parts essentially of plastic or wood or a composite material, such as a glass fiber reinforced plastic.

The invention will be explained in more detail with reference to the drawings. In the drawings, functionally identical elements are referenced with the same reference numerals. In it shows:

Furthermore, the cleaning device according to the invention has second identical parts 30 designed as side parts and third equal parts designed as spacers. Ie 40 up. Both the second identical parts 30 and the third identical parts 40 have cylindrical second recesses 32 and third recesses 42 for receiving a part of the fastening means 20. Furthermore, fourth recesses 34 are provided in the second identical parts 30 for receiving nuts 33. As a result, the second identical parts 30, which are designed as side parts, can be horizontally adjoined to one another with a negligible gap, even if first fastening means 20 are introduced. Furthermore, fourth identical parts 50 with recesses 51 and dovetail-shaped shaped pieces are formed on the respective head ends 52 for easy connection of the fourth identical parts 50 to the second identical parts 30. In addition, the fourth identical parts 50 have cylindrical, preferably continuous fourth notches 54. By means of the fourth identical parts 50, a flat end surface can be formed both on the underside of a stack consisting of first identical parts 10 and on its upper side.

FIG. 2 or FIG. 3 show a possible embodiment of a modular design or assembly of a module 100. According to the illustration of FIG. 2, a second side wall is inserted into the third identical part 30 already connected to a first side wall and designed as a spacer used. To save weight, the second identical parts 30 designed as side walls have fifth recesses 135. Furthermore, the second identical parts 30 preferably have guides 138 designed to selectively receive correspondingly shaped third and first identical parts 30 and 10, respectively, as a dovetail design. In the inserted state, the light dimension between the illustrated side parts is determined by the length of the spacers. Furthermore, by the spacing of the guides 138 along a side part, a grid dimension or a distance between the contact points of the tubes within the two side parts is predetermined. According to FIG. 3, in the module 100 now fourth identical parts 50 are each located on third identical parts 40. Further, the associated portion of the tube 14 is located in the third recesses 51 of the fourth identical parts 50. In the illustrated embodiment, the tube 14 is enclosed with elastic sheaths 140 at the resting points in order to form a positive and non-positive connection. Bond between the tubes 14 to ensure, if additionally first identical parts 10 are inserted into the guides 138.

FIG. 4 shows a possible embodiment of an almost completed module 100 comprising a multiplicity of tubes 14 embedded between first identical parts 10 and between first and fourth identical parts 10 and 50, respectively. Furthermore, threaded rods are inserted through the module 100 as first fastening means 20 in order to secure the inserted common parts against slipping when the module is raised and to increase the stability of the modules by deriving at least part of the weight of the stack on the side parts.

An advantage of the illustrated embodiment is that the use of identical parts, which additionally have advantageous formations, makes it possible to assemble the modules easily and quickly, without requiring a large number of trained skilled workers. Furthermore, the modules can be transported both as a kit and in the finished state to the place of use. In particular, the modular design using identical parts, especially for larger plants for the production of drinking water, such as in seawater desalination plants, a significant reduction in costs. Furthermore, the static calculations for the mostly steel support frames, which are very complex to perform, especially in the case of large installations, are eliminated. Also, a complex control of the quality of welds and the dimensional accuracy of the racks can be omitted.
