CZ25546U1 - Means for repeated cleaning of drinking bowls for domestic animals from mineral deposits and microbes - Google Patents

Description

Technical field

The technical solution relates to a means for repeated cleaning of domestic drinking fountains from mineral deposits and microbes.

BACKGROUND OF THE INVENTION

Drinking cold and warm service water used in industrial, agricultural and similar buildings or in households contains, depending on the water source, soluble mineral salts, in particular bicarbonates or hydrogen sulphates and sulphates of calcium, magnesium, resp. iron in various concentrations. The presence of dissolved calcium and magnesium salts in water is referred to as water hardness.

When such drinking or service water is used, the bicarbonate anion is converted to a carbonate anion by standing and also by subsequent evaporation of water, for example in domestic animal feeders, with the release of carbon dioxide, the so-called secondary karst phenomenon. The carbonate anion then forms a sparingly soluble salt of calcium and / or magnesium, which, when excreted from the solution, entrains calcium, magnesium or iron sulphates with it, resulting in the formation of mineral deposits, so-called limescale, respectively. sintr. Alongside this, porous scale builds up the proliferation of microorganisms, especially bacteria, including cyanobacteria (cyanobacteria), but also the proliferation of various types of algae (Kalina T .; Váňa J. Cyanobacteria, algae, fungi, bryophytes and similar organisms in contemporary biology. Prague: Karolinum, 2005.). In addition to reducing the aesthetic appearance of the feed devices due to the formation of compact coatings, these processes also lead to possible infections of pets. This is due to the possible occurrence and multiplication of pathogenic bacteria, in particular Legionella pneumophila (Ryan KJ; Ray CG (editors). Sherris Medical Microbiology (4th ed.) McGraw Hill 2004.), Listeria monocytogenes and Listeria ivanovii (Vařejka F. Mráz O .; Smola J. Special veterinary microbiology. Prague: State Agricultural Publishing House, 1989.). In addition to animals, the presence of these bacteria may also cause, in children, pregnant women or debilitated adults, the relevant diseases, sometimes fatal outcome (Collective of authors. Role of Environmental Surveillance in Determining the Risk of Hospital-Acquired Legionellosis: A National Surveillance Study With Clinical Correlations).

Currently, there is no suitable means on the market for effective and efficient descaling, decalcification, and disinfection of the surfaces of pet feeding equipment. Limescale is removed mechanically with the risk of damage to cleaned surfaces, or amateurish by boiling them in various concentrated aqueous solutions of acetic or citric acid, etc., very often with doubtful results and with the possibility of damage to the equipment. Disinfection of these devices is usually sporadic.

The essence of the solution

The object of the technical solution is a means for repeated cleaning of domestic drinkers from cold deposits contaminated with microorganisms. The composition is based on the action of an aqueous solution of trihydrogenphosphoric acid at a concentration of 10 to 30% by weight, and further comprising a mixture of non-ionic surfactants in an amount of 0.01 to 0.5% by weight, and / or cationic surfactants in an amount of 0.01 to 0%. %, As a wetting agent or as a disinfectant.

It is known that trihydrogenphosphoric acid and its phosphate salts are commonly used in the food industry (E 338-E 341) and in the food industry, for example its dilute solution is contained in Coca-Cola and other ionizing drinks.

The action of the aqueous solution of trihydrogenphosphoric acid at the indicated concentration is based on the reaction of insoluble calcium, magnesium and iron carbonates, whereby their protonation produces soluble bicarbonates. These then react to form labile carbonic acid, which decomposes into carbon dioxide and water present in the air. Cations of calcium, magnesium, resp. The iron forms the corresponding water-soluble dihydrogen phosphates when reacted with phosphoric acid. The reaction also releases insoluble calcium sulfate into the solution and cleans the surface of the valve fittings. The whole process is made possible by the fact that phosphoric acid is more than five orders of magnitude stronger than carbonic acid. The dissolution of the porous limescale also releases any microbial mucus that is present, which is finally removed by rinsing the surface with water. The present cationic surfactant acts disinfectant on the present microorganisms and antiseptic, the present diluted phosphoric acid strengthens both effects.

The advantage of the technical solution to the utility model is its high cleaning activity with simultaneous disinfection effect, the possibility of repeated use of the device is highly economical and ecological, especially due to the very easy biodegradability of the device in the environment. The use of the composition in concentrations according to the invention to the utility model does not damage the metal or plastic surface of the cleaned supply devices.

The object of the technical solution to the utility model is illustrated by the following examples, without limiting the scope of the utility model.

Examples of technical solution

Example 1

To 250 g of a cleaning aqueous solution containing 22 wt. % phosphoric acid, CAS No. 7664-38-2, 0.05 wt. % N-benzyl-N, N-dimethyloctadecan-1-aminium chloride, 0.1 wt. For example, the dismounted pet feeder, 150 ml, is immersed at room temperature to wet the surface with detergent. Contact of the surface of the drinker parts clogged with mineral deposits with the detergent solution generates gaseous carbon dioxide, resulting in the formation of gas bubbles and foam on the surface. The release of the bacterial coagulate from the surface of the object to be cleaned may optionally be observed. The cleaning solution is occasionally mixed. After the carbon dioxide evolution is complete, the solution is reused and the drinker parts are rinsed with a stream of water.

Depending on the amount of mineral deposits and the frequency of reuse, the entire process takes 2 to 10 minutes. If the trihydrogenphosphoric acid present in the solution is completely converted to water-soluble calcium dihydrogenphosphate, the formulation ceases to function and should be replaced with a fresh formulation. An amount of 100 g of the composition of the above is capable of removing 20 g of limescale (such as calcium carbonate).

Example 2

A drinking metal or plastic bowl of about 500 ml volume is filled with about 100 g of a cleaning aqueous solution composition containing 20 wt. % trihydrogenphosphoric acid, 0.01 wt. % Of dimethyl-N-dodecyl-N-benzylamino bromide (ajatin) and 0.01 wt. oxethylated lauryl alcohol (Brij - 35). The inner surface of the cup is wiped with a circular motion until the surface of the cup is foaming and the surface is clean and free of original deposits. The next operation is the same as in Example 1.
