and the mud guiding backflow pool 50 is communicated with the inclined tube sedimentation pool 10 through a mud guiding pipe 40.
The inlet 401 of the mud pipe 40 is perpendicular to the bottom of the mud bucket 20. The inlet 401 of the mud guide pipe 40 is vertical to the bottom of the mud bucket 20: in order to sufficiently discharge the accumulated mud in the mud bucket 20, the inlet 401 of the mud pipe 40 is arranged perpendicular to the bottom of the mud bucket 20. When the direction of the sludge precipitated by the inclined tube is perpendicular to the direction of the water flow and the sludge guide tube 40, the sludge can be discharged smoothly.
The inlet 401 of the mud pipe 40 is located near the center of the bottom of the mud bucket 20. So that the accumulated mud in the mud bucket 20 can be fully discharged;
compared with the conventional sludge guide pipe structure inclined tube sedimentation tank 10 device of the coal chemical wastewater treatment system, the device has stability on one hand, increases the safety during debugging and production on the one hand, is convenient for debugging and production, and has great economy in the long run.
As shown in fig. 2, the inlet 401 of the mud pipe 40 is 100mm from the bottom of the mud bucket 20. Make long-pending mud in the bagger 20 can fully discharge, according to engineering practice experience, when being greater than 100mm apart from the bottom of bagger 20, long-pending mud can accumulate in a large number, and unable in time discharge causes the unable clearance of a large amount of mud that dies in bottom, when mud pipe 40 is less than 100mm, takes place easily that mud pipe 40 blocks up, influences the mud system of arranging.
Further, the mud guide pipe structure further comprises a gate valve, and the mud guide pipe 40 further has an outlet 402; the gate valve is connected in series to the outlet 402 of the mud guide pipe 40 and is used for blocking the outlet 402.
