Detailed Description

The technical scheme of the utility model is specifically explained below in connection with the embodiment, the utility model discloses an accurate concentrated plate filter plate, it is shown in combination with fig. 1-5, including hollow filter plate frame 1, be provided with just, anti-filter surface in the filter plate frame 1, just the play liquid hole 13 has been seted up on just, the anti-filter surface. The liquid outlet hole 13 is communicated with the front filtering surface and the back filtering surface, and when the filtering is carried out, the filtered liquid after the filtering liquid passes through the front filtering surface and the back filtering surface flows out through the liquid outlet hole 13. When the filter plate is used specifically, a filter membrane or filter cloth is selectively coated outside the filter plate frame. When the filter plate frame 1 is externally provided with a filter plate which is not shown, the outer side of the filter plate frame is provided with a circulation hole 15. And the filter membrane is welded, and the surface of the filter cloth is directly sleeved with the filter plate frame 1 and is connected with the filter plate frame through ultrasonic welding so as to ensure no leakage point.

The front filtering surface and the back filtering surface are respectively the front surface and the back surface of the filter plate frame. The positive filtering surface is composed of hollow transverse liquid flow grooves 12 uniformly distributed on the filter plate frame, a gap is arranged between every two adjacent transverse liquid flow grooves 12, and the transverse liquid flow grooves 12 are communicated with each other through the filter plate frame 1.
