Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a water conservancy baffle device for sedimentation tank goes out mill weir, includes pond 1, and cavity 2 has been seted up to the inside of pond 1, and the upper end of pond 1 is provided with apron 3, and the upper end fixedly connected with air cover 4 of apron 3, the inside both sides of air cover 4 fixedly connected with the same abatvoix 5 respectively, and the lower extreme of air cover 4 is provided with out the ditch 6, and the left and right sides of going out the ditch 6 is fixed with the same baffle 7 respectively.
Furthermore, the length of the cover plate 3 is the same as that of the pool 1, and the outer end surface of the cover plate 3 is flush with that of the pool 1, so that the overall structure is beautiful.
Further, polyester fiber 51 is arranged inside the sound-absorbing plate 5, the sound-absorbing plate 5 is designed in an inclined structure, two sound-absorbing plates 5 are symmetrically arranged on the vertical center line of the air hood 4, sound absorption treatment is carried out when water flow impacts the baffle 7, and noise pollution is reduced.
Further, the width of baffle 7 is 1m, and baffle 7 is 45 inclined structure designs, and baffle 7 is provided with two about the vertical central line symmetry of outlet channel 6, and the maximize blocks silt etc..
Furthermore, the lengths of the sound-absorbing plate 5 and the baffle plate 7 are the same as that of the water outlet channel 6, so that better sound-absorbing and blocking effects are achieved.
The working principle is as follows: firstly, after sewage enters a sedimentation tank, because of the difference of water temperature or density between inlet water and the sedimentation tank, the mixed liquid often forms density flow, the mixed liquid entering the sedimentation tank moves along the bottom of the tank, suspended matters can rise along side walls to enter an outlet weir, and further the quality of outlet water is influenced, impurities such as sludge in the sewage rise along walls at the moment, the impurities contact with baffle plates 7, splayed structures are formed between the baffle plates 7, silt and the like passing through an outlet channel 6 are blocked, the length and the angle of the baffle plates 7 can effectively block most of the silt, when a small part of the silt is about to enter the outlet channel 6, the silt is blocked by an acoustic board 5, the acoustic board 5 and the baffle plates 7 are matched to form a structure for blocking the silt, and when water flow impacts the baffle plates 7, a large amount of noise can be generated, and the noise can be absorbed by polyester fibers 51 in the acoustic board 5 at the moment, effectively reducing noise pollution and optimizing the use environment of the sedimentation tank.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
