Description

Hot water distributor for heating with foreign matter removal function {HOT WATER DISTRIBUTOR HAVING FUNCTION TO REMOVING SCALE}

The present invention relates to a hot water distributor for heating, and more particularly, a hot water distributor for heating having a foreign matter removal function that maximizes the filtering effect and heating efficiency by separating and filtering foreign substances with large specific gravity and foreign substances with small specific gravity contained in heating water is about

In general, a hot water distributor for heating distributes hot water supplied from a boiler, supplies it to a heating pipe, recovers water cooled through a heating process, and supplies it to the boiler for reheating, so that heating is performed.

However, there is a problem in that various foreign substances are generated in the hot water due to long-term use, the heating efficiency is lowered by the generated foreign substances, and consequently, energy consumption is increased, thereby increasing the heating cost. Here, foreign substances mainly consist of iron powder separated from metal materials and mineral substances (calcium, magnesium, minerals, etc.) contained in water.

A hot water distributor for heating that removes foreign substances has been disclosed as Utility Model No. 20-1989-0013772. By installing a hot water supply pipe and a return pipe vertically between two opposing support plates, the opening and closing valve is connected to the bottom of the hot water supply pipe. In the conventional one, the hot water supply pipe installed in the upper part is made by inserting a strainer into the opening, and installing a vortex pipe having a plurality of vortex openings on the inner peripheral surface of the opening end.

In such a conventional hot water distributor for heating, hot water supplied from the boiler through the hot water supply line is filtered by a strainer in the hot water supply pipe, passed through the on/off valve, and supplied to the heating coil, and hot water is supplied while causing a vortex phenomenon by the vortex port of the vortex pipe. Therefore, as only pure hot water is filtered by the filter while scraping away foreign substances or scales on the inner peripheral wall of the hot water supply pipe, impurities or dirt do not aggregate inside the pipe, so scale does not occur and the inside of the pipe is not corroded. However, since the circulation process of hot water is smooth, efficient heating effect can be expected and the lifespan of the pipe can be extended. Excessive minerals (minerals, magnesium, etc.) fix the rotation shaft of the pump motor, leading to shortened lifespan and malfunction. In addition, since the strainer must be separated from the hot water supply pipe during cleaning, it takes a long time to work, such as discharging and supplying hot water, and polluting the environment.

In addition, Utility Model Registration No. 20-0200099 relates to a distributor for a hot water boiler, in a distributor body having one exhaust passage, an inlet passage, and a plurality of exhaust passages. One end of the fitted stainless steel tubular filter mesh is caught, and the other end of the filter mesh is fixed by tightening the screw cap, and when the screw cap is unscrewed, the filter mesh can be collected.

These hot water boiler distributors cleanly filter iron oxide or foreign substances contained in the hot water through a filtration net and then flow into the piping line through the discharge path. And if residue is attached to the filter screen, loosening the screw stopper makes it easy to clean, so cleaning is convenient. There is a problem in that a separate part is required, which increases the manufacturing cost.

On the other hand, a hot water distributor having a scale removal function to solve this problem has been registered as Patent No. 10-1082964. In the hot water distributor having a scale removal function, a hot water supply pipe for distributing and supplying hot water to a heating pipe; a hot water return pipe disposed adjacent to the hot water supply pipe and through which water of the heating pipe is recovered; and a foreign material removing means installed to remove the foreign material, wherein the foreign material removing means includes: a shut-off valve having one side connected to at least one of the hot water supply pipe and the hot water return pipe to be disposed downwardly; and a foreign material collection container connected to the other side of the shut-off valve and formed so that foreign matter is deposited therein by its own weight, wherein the hot water supply pipe has an inlet for inflow of hot water protruding upward and formed, and the hot water return pipe is hot water The outlet for the exhaust of the inlet and the inlet protrude upward and are alternately formed, and a valve installation part in which the shut-off valve is installed below the hot water supply pipe and the hot water return pipe close to the inlet and the outlet is formed.

Since such a hot water distributor does not have a foreign substance removal means installed inside the hot water supply pipe or the hot water return pipe, it is possible to secure a smooth flow of hot water, thereby improving heating efficiency, and preventing overload of the circulation pump, thereby prolonging the life of the boiler. Although it has the effect of extending and reducing maintenance costs, it can only remove relatively heavy iron powder, but it cannot remove floating matter floating in the water or mineral substances such as calcium, magnesium, and minerals contained in the water. There is a problem in that heating efficiency is lowered as it is deposited on the surface and acts as a factor to obstruct the flow of water. In addition, the collection container is separated after blocking the inflow of hot water through the operation of the valve.

Public Utility Model No. 20-1989-0013772 (1989.08.09) Registered Utility Model No. 20-0200099 (2000.08.07) Registered Patent No. 10-1082964 (2011.11.07)
