What type of floor drain is this and can I connect pipes to it?
It is not made for more pipes, it is a floor drain and the only way to hook more pipes t it is to break up the floor and tie into 3" line that drain does eventually tie into. 

This picture of the drain cap I was referring t. It is like the older cast iron type. Looking up this type of drain that is around now have openings all over it.


 The way it is supposed to work is, the water is not supposed to go directly into the drain in the center. It fills the "cup" around the perimeter, catching any objects that get washed in by the flow of water. The objects will settle in the bottom of the catch basin and the water will fill up enough to pour over the edge and go down the waste pipe in the center.
