Referring to fig. 2-3, the turbulence mechanism comprises a cylinder 23, an inner concave part is arranged at the upper end of the cylinder 23, the inner concave part is rotationally connected to the pipe wall of the overflow pipe 12 through a sealing bearing, the cylinder 23 is sleeved in the circular ring 15 and is provided with a plurality of rectangular holes, a deflector 30 is obliquely and fixedly connected in each of the plurality of rectangular holes, one end of the deflector 30 extends into the cylinder 23 and is provided with a bending part, a toothed ring 24 is sleeved on the pipe wall of the overflow pipe 12, the lower end of the toothed ring 24 is fixed at one side of the inner concave part through a connecting block, one side of the end cover 10 is rotationally connected with a rotating shaft and a rotating shaft through a sealing bearing, a driving gear 26 is fixedly connected to the shaft wall of the rotating shaft, a second motor 11 is fixedly connected to the upper end of the end cover 10, a driven gear 27 is fixedly connected to the shaft wall of the rotating shaft, the driven gear 27 is meshed with the driving gear 26, a transition gear 28 is fixedly connected to the shaft wall of the rotating shaft, and the transition gear 28 is meshed with the toothed ring 24;
The lower extreme fixedly connected with spoiler 17 of barrel 23, a plurality of breach has been seted up to the lateral wall of spoiler 17, all fixedly connected with spoiler 22 in a plurality of breach, the lower extreme of spoiler 17 is provided with the flaring portion, flaring portion and the inner wall contact of feed body 1, the lower extreme inner wall of spoiler 17 is located a plurality of spoilers 29 of fixedly connected with in the flaring portion, the lower extreme fixedly connected with rubber pad 25 of end cover 10, rubber pad 25 and the upper end contact of barrel 23, fixedly connected with horizontal pole 21 in the spoiler 17, fixedly connected with impeller 20 on the pole wall of horizontal pole 21, impeller 20 and barrel 23 and overflow pipe 12 coaxial setting, the lower extreme mouth of pipe department of overflow pipe 12 cup joints with impeller 20.
The invention is provided with a turbulent flow mechanism, when in use, the second motor 11 is started to drive the rotating shaft to rotate the driving gear 26, the driving gear 26 is rotated to drive the driven gear 27 to rotate the rotating shaft and the transition gear 28, the transition gear 28 is rotated to drive the toothed ring 24 to rotate the cylinder 23, when the cylinder 23 is rotated, the turbulent flow sheet 29 and the turbulent flow sheet 22 are utilized to drive sewage to form a rotating flow field, so can utilize mechanical force to guarantee that the required rotatory flow field of separation silt can be formed in feed body 1 and awl section of thick bamboo 4 when sewage pressure is not enough, when intake pressure is enough, sewage pass a plurality of rectangular holes and under the effect of guide plate 30 and kink, form stranded rivers and cut into feed body 1 in, finally form stable rotatory flow field in awl section of thick bamboo 4, make the separation that silt can be abundant.
It should be noted that the term "comprises," "comprising," or any other variation thereof is intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises an element.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
