Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
Referring to fig. 1-4, a sludge cleaning device of a sewage treatment secondary sedimentation tank comprises a secondary sedimentation tank body 1 and a supporting truss 5, many mud suction pipes 7, the mud suction pipe 7 top is connected with the dredge pump, be equipped with support column 3 in the middle of two heavy pond bodies 1, support truss 5 supports between support column 3 and two heavy pond bodies 1 outer fringe, install slewing mechanism 4 between support column 3 and the support truss 5, be equipped with walking gyro wheel 6 between the support truss 5 other end and two heavy pond bodies 1 outer fringe, a plurality of consecutive and concentric annular slot 2 that set up are seted up to two heavy pond body 1 diapire, 7 bottom rigid couplings of every mud suction pipe have one scrape mud spare 8, scrape mud spare 8 and seted up both ends all with external communicating passageway 9, mud suction pipe 7 and passageway 9 intercommunication, it is whole to scrape mud spare 8 and be the arc structure, it is the same with annular slot 2 shape to scrape mud spare 8 bottom surfaces, and scrape mud spare 8 bottom surfaces and tangent with annular slot 2.
The device sets the bottom of a secondary sedimentation tank body 1 into a continuous annular groove 2, the vertical section of the annular groove 2 is of a triangular structure, the vertical sections of a plurality of sequentially connected and concentrically arranged annular grooves 2 are of a tooth-shaped structure, a mud scraping piece 8 is an arc-shaped pipeline, the vertical section of the mud scraping piece 8 is of a triangular structure, or the vertical sections of a plurality of sequentially connected and concentrically arranged annular grooves 2 are of a wave-shaped structure, preferably, the annular groove 2 is of a triangular structure, the bottom of the structural tank is provided with an inclined plane which can promote the mud to be deposited at the sharp corner position of the triangular structure, then when a supporting truss 5 rotates around a supporting column 3, as the mud scraping piece 8 is provided with a channel 9, the two ends of which are communicated with the outside, when the mud scraping piece 8 moves in the annular groove 2, the mud is scraped into the channel 9 of the mud scraping piece 8, and as the two ends of the channel are communicated, the mud is prevented from being lifted and dispersed again when the mud, the mud that gets into in the passageway 9 is directly siphoned away by suction pipe 7, because suction pipe 7 communicates with each other with passageway 9, and passageway 9 only both ends communicate with each other with the external world, passageway 9 is towards a direction motion again, when suction pipe 7 absorbs the mud in the passageway 9 this moment, avoid suction pipe 7 to influence the sediment of mud on every side, also avoid mud on every side simultaneously to be raised, the bottom of the pool is calmer stable going on more when this device can make two heavy ponds suction mud, reduce the probability that the mud of sediment is raised once more, improve the efficiency that mud was got rid of.
One end of the mud scraping piece 8 facing water is provided with a chamfer 10, and the other end facing water is provided with a chamfer to further avoid lifting the settled sludge.
The vertical section of the mud scraping piece 8 is an isosceles triangle with a vertex angle of 20-45 degrees, the annular groove 2 and the mud scraping piece 8 are both provided with a triangular structure, the inclined plane is inclined more and more favorable for sludge to be deposited at the position of the sharp corner at the bottom of the annular groove 2, the sharp corner at the bottom of the annular groove 2 is optimized to have an angle of 30 degrees, the height is optimized to be 200-300 mm, and the wall thickness of the mud scraping piece 8 is 1-1.5mm, the annular groove 2 with the angle and the depth promotes the sludge to be deposited at the sharp corner position, the supporting truss 5 rotates for a circle according to the speed of the secondary sedimentation tank and the sludge deposition, the sludge deposition height is two fifths to two thirds of the depth of the annular groove 2, therefore, when the sludge is always in the half waist position of the annular groove 2 and the sludge scraping piece 8 scrapes the sludge, the sludge suction pipe 7 timely draws away the sludge entering the channel 9, and the precipitated sludge can be prevented from being lifted again.
