Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific examples, which are not intended to limit the scope of the utility model.

As shown in fig. 1, fig. 2, fig. 3 and fig. 4, the cooling wastewater filtering and circulating device of the present embodiment includes a first pipeline 1, a second pipeline 2 and a filtering device 3, the filtering device 3 includes a cylindrical housing 31 and a filter screen 32 located inside the housing 31, the filter screen 32 and a gap is provided between the housing 31, the bottom of the filter screen 32 is inclined toward the second pipeline 2, the included angle between the axis of the filter screen 32 and the vertical surface is 10-30 °, the outlet of the first pipeline 1 is communicated with the inside of the filter screen 32, the inlet of the second pipeline 2 is communicated with the liquid outlet of the housing 31, the outlet of the second pipeline 2 is provided with a cooling water main pipe 4, and the bottom of the housing 31 is provided with a slag outlet 33 communicated with the filter screen 32. During the use, waste water after cooling device cooling gets into filter screen 32 of filter equipment 3 through first pipeline 1, and filter screen 32 holds back the tiny granule of plastics in the waste water, and the water after the filtration flows into casing 31 to export from second pipeline 2, get into cooling water and be responsible for 4 in the recycle. In the utility model, the filter screen 32 is obliquely arranged, and the bottom of the filter screen is inclined towards the direction of the second pipeline 2, so that plastic particles trapped in the filter screen 32 (mainly on the side wall opposite to the liquid inlet of the filter screen 32) are favorably concentrated at the bottom of the filter screen under the action of water flow and inclination of the filter screen, the service time of the filter device 3 is prolonged, and the filter screen is convenient to clean.
