Detailed Description

The following describes the embodiments of the present invention with reference to the accompanying drawings.

The following examples are given for the purpose of illustrating the present invention in a clear manner and are not intended to limit the scope of the present invention. Other variations and modifications of the present invention will be apparent to those of ordinary skill in the art based on the following description, and it is within the spirit of the present invention that such variations and modifications are within the scope of the present invention.

Referring to fig. 1, the utility model discloses a sludge discharging device with flushing function, including flocculation basin, perforation sludge discharging pipe, the perforation sludge discharging pipe transversely runs through the mud bucket of flocculation basin bottom, the perforation sludge discharging pipe 1 divides into the sludge discharging pipe section of arranging in the mud bucket, extends the mud storage pipe section outside the pond from the mud bucket, the perforation sludge discharging pipe end connection quick-open mud valve outside the pond; the bottom of the quick-opening mud valve is provided with a mud outlet of the mud valve;

the sludge storage pipe section is sequentially provided with a manual knife gate valve 8, a flushing tee 2 and a quick-opening sludge discharge valve 3 from the end adjacent to the flocculation tank; the washing tee joint 2 is connected with a washing pipeline 5, the other end of the washing pipeline 5 is connected with a water source, the water source is clear water or pressure water at the upper part of the flocculation tank, and the washing pipeline 5 is sequentially provided with a washing control valve 6 and a flowmeter 9 from top to bottom. The hand knife gate valve manually opens and closes the perforated mud pipe;

The quick-open mud valve 3 is provided with an integrated controller 7 for controlling the opening and closing of the flushing control valve 6 and the quick-open mud valve 3.

Example one

The utility model discloses can be used to adopt the flocculation basin (sedimentation tank) of perforation mud pipe, the row's mud system of folded plate (net) flocculation basin, pipe chute sedimentation tank etc. for example.
