Description
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a filter for removing foreign substances in a boiler installed inside a flow switch connected to a direct water pipe to filter out foreign substances contained in direct water. More specifically, And more particularly, to a filter for removing foreign substances in a boiler, which can effectively extend the service life of the boiler.
Generally, a boiler using gas and petroleum as a fuel heats the primary heat exchanger with the combustion heat of the burner so that the primary heat exchange is performed, and then circulates the heat to the main heating water.
And a second heat exchanger in which the external direct water and the heating water are selectively heat-exchanged, thereby obtaining hot water.
Therefore, in the heat exchanger, the primary heat exchanger and the secondary heat exchanger are installed separately in one boiler.
That is, the conventional heating pipe and the hot water pipe circuit are controlled by a three-way valve so that a part of the heating water heated from the primary heat exchanger is supplied for indoor heating or sent to the secondary heat exchanger for heat exchange to obtain hot water.

(Patent Document 0002) Registered Utility Model Registration No. 20-0207183 (Registered on May 10, 2000)
However, the conventional filter has the following problems.
First, since the size of the mesh formed at one end of the filter is larger than the size of the foreign matter contained in the direct water, the foreign matter can not be completely filtered by the mesh and flows into the inside of the boiler and accumulates in the combustion part and the channel part. And there was a claim from consumers due to noise generation, poor operation of the boiler such as leakage, and the like.
Secondly, since the meshes are formed in hemispherical shape at one end of the filter, the life of the filter is shortened because of a small cross-sectional area, so the filter has to be frequently replaced.
Third, since the foreign matter contained in the direct water flows into the inside of the filter and is filtered by the hemispherical mesh formed on one side, there is a deadly plug which is lost as a filter if one side of the mesh located inside the filter is clogged.
SUMMARY OF THE INVENTION The present invention has been made in order to solve such problems of the prior art, and it is an object of the present invention to provide a filter having a mesh of # 40 over the entire outer circumferential surface of a small- And the foreign matter is filtered on the entire outer peripheral surface of the small-diameter portion.
Another object of the present invention is to provide an auxiliary mesh of # 40 not only on the circumferential surface of the small diameter portion of the filter but also on the flange of the large diameter portion so as to maximize the area for filtering the foreign matter so that the life of the filter can be maximized .
According to an aspect of the present invention for achieving the above object, there is provided a foreign matter removing filter for a boiler installed inside a flow switch fixed to one end of a direct water pipe and supported by a filter plug, Wherein an opening portion is formed on the opposite side of the mesh forming the filter plug and an outer portion of the opening portion is formed with a large diameter portion which is in close contact with the inner pipe of the flow switch and an auxiliary mesh through which the direct water passes is formed in the flange of the large diameter portion A rim portion having a vertical surface is integrally formed at one side of the large diameter portion. An inclined surface in the form of a funnel is formed in the flow switch. A vertical surface formed on the rim portion is linearly connected to the inclined surface, Wherein the filter for removing foreign substances in the boiler / RTI >
The present invention has the following advantages over the conventional device.
First, the # 20 mesh smaller than the size of the foreign matter contained in the direct water is formed over the entire outer circumferential surface of the small diameter portion of the filter, so that the foreign matter can be completely filtered by the mesh, thereby preventing the foreign matter from flowing into the boiler interior Accordingly, the clogging phenomenon inside the boiler can be prevented beforehand, so that it is possible to fundamentally solve the problem of receiving a claim from consumers due to noise, leakage, and poor boiler operation.
Secondly, since the meshes are formed on the flange of the large diameter portion as well as the entire small diameter portion of the filter, the lifetime of the filter can be maximized by increasing the cross-sectional area of the mesh, thereby increasing the replacement period of the filter.
Third, the foreign matter contained in the direct water is filtered by the mesh formed on the entirety of the small diameter portion and the auxiliary mesh formed on the flange before the foreign matter contained in the direct water is introduced into the filter, so that the function of the filter is not lost even if a part of the mesh or the auxiliary mesh is clogged.
Fourthly, a rim portion having a vertical plane is formed to protrude on the large diameter portion, and the flow switch is provided with a slope surface to which a vertical plane is connected. Thus, the flow path can be secured by the rim portion. So that it can be filtered.
