Background technique

It is known to collect the cleaning balls for cleaning closed fluid flow systems, such as heat exchangers in a balltrap, and then attract them from the balltrap to a collection Ball room. Ball catchers may be configured to extend at substantially any angle from the main flow duct.

At present, it is increasingly popular to utilize a ball catcher extending at a 90 degree from the main fluid flow pipe, for example a ball catcher is often referred to as a "T" type ball catcher (such as "10" in the accompanying drawings). ).

Such ball catchers are typically provided with a screen or screen element 100 extending from the input opening 12 in the "T" shape to the ball catchers themselves.

The inventor of the present case found that the multiple "T" type ball catchers currently used cannot achieve the purpose of collecting all the cleaning balls in the system. That is, the fluid flow patterns in the "T" ball catchers currently in use cause some of the wash balls to collect in areas of the screen causing them not to flow from the The ball catcher is sucked out into the ball collection chamber.

Therefore, there is a need to provide a plurality of blocking elements for use with ball catch screens to enhance movement of the plurality of wash balls through the ball catcher.

detailed description

The present invention is a plurality of blocking elements for enhancing the movement of the cleaning balls through the ball catch screens of the ball catcher in a closed fluid flow system.

The principles and operation of the blocking elements used in accordance with the present invention with catch screens may be better understood with reference to the accompanying drawings and the accompanying description.

Referring now to the accompanying drawings, FIG. 1 shows a transparent view of a "T"-shaped ball catcher 2, which has a ball catch housing 10 with a water inlet 12, a water outlet 13 and a ball catch extension 10e. Also shown is a ball catch screen 10' deployed within the ball catch housing 10. It can be understood that, in such a plurality of ball catchers, the main fluid flow path is located at the water inlet 12, a water outlet 13 and guides the plurality of cleaning balls through a secondary fluid flow path to the Between the three in the catch extension.

As noted above, the present inventors sought to have some of the wash balls collect at the catch screen for the plurality of fluid flow patterns in the plurality of "T" ball catchers currently in use. A solution to the problem in multiple areas where the cleaning balls are not sucked out of the ball catcher into the ball collection chamber. The present invention is a solution to this problem.

The ball catch screen 10' is provided with a tapered inlet 12' which tapers inwardly and is connected to a first screen section 10'a of the ball catch screen 10'. The first screen section 10'a extends from the inlet to a bend and a second screen section 10'b with the ball catcher screen extends from the bend 14 to connect to the first The first screen section 10'a and the ball-catching extension section 10e of the second screen section 10'b. The catch screen 10' illustrated here is configured with a 90 degree elbow 14.

The inventors of the present case found that by deploying a plurality of solid (solid) blocking elements on at least a part of the tapered inlet 12' and on the 90-degree elbow 14, as shown in the accompanying drawings, the A plurality of fluid flow patterns within the ball catcher may be altered sufficiently sufficiently that the plurality of wash balls are directed to regions of the ball catch screen such that the plurality of wash balls flow from the The ball catcher is sucked out into the ball collection chamber.

While the drawings described here are intended to illustrate a preferred embodiment of the plurality of ball-catching screen blocking elements of the present invention, it is easy to understand that the plurality of blocking elements on the described ball-catching screen The size, shape and exact position may vary within the scope of the invention.

That is to say, the inventors of the present application have found that the preferred location of the tapered blocking element 50 is in the area relative to the 90 degree extension 16 . Preferably, but not necessarily, said conical blocking element 50 is configured to cover thirty percent of said circumference of said conical inlet.

As illustrated therein, at least a portion of the 90 degree elbow 14 includes a generally flat solid region 14a approximately 45° relative to both the first and second screen sections 10'a, 10'b. degree to configure. It is easy to understand that the substantially flat solid area 14 a is also located at an angle of approximately 45 degrees with respect to the fluid flow path between the water inlet 12 and the water outlet 13 of the ball catching housing 10 . The present inventors have found that extending the solid area surrounding the area 14a also enhances the plurality of fluid flow patterns within the ball catcher to better guide the plurality of cleaning balls to the A plurality of areas of the ball catching screen is used to facilitate the plurality of cleaning balls to be sucked out from the ball catching device into the ball collecting chamber. To this end, a plurality of blocking elements 52 and 54 are respectively disposed in the first screen section 10'a and the second screen section 10'b so as to substantially circumscribe the solid region 14a.

It should be noted that an innovation of the present invention is a method of enhancing the movement of the cleaning balls through the ball catcher in a closed fluid flow system, once fluid flow is initiated, through multiple barriers of the ball catcher screen This in turn improves the fluid flow through the ball catcher.

Yet another innovation of the present invention is the deployment of the plurality of blocking elements on the catch screen. It should be noted that each of the plurality of blocking elements may be separately formed, and such deployment may be performed at the time of manufacture of the catch screen. Alternatively, the plurality of blocking elements may be integrally configured with the screen. That is, the screen itself may be fabricated with solid regions such that when the ball catch screen element is fabricated, the locations of the solid portions of the screen material correspond to barriers. The various preferred positions of elements 50, 52 and 54 are described.

It should be appreciated that separately manufactured barrier elements may be installed as aftermarket components for use on existing ball catchers retrofitted for use in closed fluid flow systems.

It should be understood that the above descriptions are intended as examples only and that many other embodiments are possible within the spirit and scope of the invention.
