Benefits of technology
Enhances system uptime by allowing convenient cleaning and debris management, protecting against downstream upsets by diverting debris to a collection receptacle during faults, while maintaining liquid flow.
Problems solved by technology
Also, the typical strainer device is not suited for the receipt and processing of objects that are the result of an upstream breakage or destruction.

Embodiment Construction
[0022]Reference is now made to the block diagrams illustrating different modes of operation of the strainer and associated control system for the strainer. One of the purposes of the control system, along with the unique construction of the strainer element, is to maximize the up-time of the system operation. Another feature that is described with regard to the block diagrams is a system for protecting against any fault event or process upset when debris or detritus become entrained in the fluid flow.
[0023]FIG. 1 is a schematic block diagram of a first embodiment of the present invention in which the strainer element is controlled for rotation by means of a timer. The second embodiment of the present invention is shown in the block diagram of FIG. 2 in which pressure sensing occurs at the strainer and the rotation of the strainer in turn is controlled by a pressure sensor that senses a pressure differential at the strainer. FIGS. 3-5 show further details associated with either the s...

Abstract
A screening apparatus that includes a strainer element used for the purpose of retaining particulate while permitting the passage of a liquid through the strainer element, a support structure for the strainer element to enable rotation of the strainer element between opposed 180 degree positions, and a control member coupled with the strainer element for controlling the rotation of the strainer element. The strainer element, in both opposed positions thereof impedes any particulate while permitting the passage of a liquid. The control member is constructed so that, in a first state thereof, the rotation of the strainer element is periodically controlled to rotate the strainer element between said opposed 180 degree positions, and in a second state thereof, inhibits rotation of the strainer element.
Description
FIELD OF THE INVENTION[0001]The present invention relates in general to strainers that may be used in such applications as filtration and fluid flow safety. More particularly, the present invention relates to an improved strainer construction as well as an associated control system. Even more particularly, the present invention relates to a method of controlling a strainer element.BACKGROUND OF THE INVENTION[0002]In the field of filtration and fluid flow safety there is relatively common use of a device that is identified as a strainer. The strainer or screening device is used to retain foreign objects. The strainer is usually a fixed position device. It is typical to provide access to the strainer for cleaning the strainer. However, this access is many times not very convenient. Also, the typical strainer device is not suited for the receipt and processing of objects that are the result of an upstream breakage or destruction.[0003]Accordingly, it is an object of the present inventi...
