[0020] The following is only a preferred embodiment of the present invention, and the protection scope is not limited to this embodiment. All technical solutions under the concept of the present invention should belong to the protection scope of the present invention. At the same time, it should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
[0021] As shown in the figure, a sand and gravel screen for sewage treatment includes a screening device.
[0022] The screening device includes a screening pool 1, a screening slot 2, an electric cylinder 3, a driving block 4 and a screen 5. The screening slots 2 are provided on both sides of the screening pool 1, the electric cylinder 3 is located in the screening slot 2, the driving block 4 is driven by the electric cylinder 3, the driving block 4 is convex, the screen 5 is connected to both sides of the driving block 4, and the screen 5 is U-shaped. A sealing groove 6 is provided on the top of the screening pool 1, a sealing plate 7 is slidably connected in the sealing groove 6, the sealing groove 6 is connected to the screening slot 2, and the bottom of the sealing plate 7 is located in the screening slot 2. During the screening process, the electric cylinder 3 drives the driving block 4 to reciprocate, so that the screening is evenly rinsed and screened, thereby improving the screening effect.
[0023] The screen 5 comprises a coarse screen 15 and a fine screen 16 . The fine screen 16 is detachably connected to the bottom of the coarse screen 15 . The diameter of the screen holes in the coarse screen 15 is larger than the diameter of the screen holes in the fine screen 16 .
[0024] A sealing plate 8 is fixedly connected to the top of the driving block 4, a water inlet pipe 9 is fixedly connected to the top of the sealing plate 8, and a flushing pipe 10 is obliquely connected to the top of the sealing plate 8. A snap-in groove is provided on the inner side of one driving block 4, and a slide groove is penetrated through the other end of the driving block 4, a snap-in plate 11 is slidably connected in the slide groove, one end of the snap-in plate 11 is snap-fitted to the snap-in groove, and both ends of the snap-in plate 11 are fitted with the screen 5. The snap-in plate 11 is provided inwardly at a collecting tank 12 on one side close to the screen 5. Sewage enters the screen 5 from the water inlet pipe 9, and the screen 5 screens the sewage. During the screening process, water is discharged from the flushing pipe 10, and the sewage is flushed obliquely, flushing light and large-volume solids into the collecting tank 12 and flushing the sludge attached to the surface of the sand and gravel.
[0025] Working principle: Sewage enters the screen 5 from the water inlet pipe 9, and the screen 5 screens the sewage. During the screening process, water flows out of the flushing pipe 10, and the sewage is tilted and flushed, and the light and large-volume solids are flushed into the collection tank 12 and the sludge attached to the surface of the sand and gravel is flushed. During the screening process, the electric cylinder 3 drives the driving block 4 to reciprocate, so that the flushing and screening are uniform during the screening, and the screening effect is improved.
[0026] After the screening is completed, the sealing plate 7 is removed from the sealing groove 6, so that the electric cylinder 3 drives the driving block 4 out of the screening groove 2 in the horizontal direction, and then the clamping plate 11 is slid out of the clamping groove and the slide groove to remove the residue in the screen 5 from both sides of the driving block 4.
[0027] In summary, the electric cylinder 3 drives the driving block 4 to move, and the sand and gravel are separated from the sewage during the initial screening of the sewage; the sewage is introduced through the water inlet pipe 9 for screening, and during the screening process, the water in the flushing pipe 10 flushes the attached sludge and flushes the light and large-volume solids into the collection tank 12.
