Description

Sewage flocculation is from row material structure

Technical Field

The invention belongs to the technical field of sewage treatment, and particularly relates to a sewage flocculation self-discharging structure.

Background

The sewage flocculation means that suspended matters in sewage are coalesced into larger particles by adding flocculant when sewage is treated, so that subsequent sedimentation and filtration operations are facilitated. Flocculation can effectively remove suspended matters, colloid substances and some dissolved substances in sewage, and improve the purification effect of water quality. Examples of commonly used flocculants are inorganic flocculants and organic flocculants. Inorganic flocculants include aluminum salts, iron salts, and the like, which chemically react with colloidal particles in the wastewater to cause them to coalesce into larger particles. Organic flocculants are mostly high molecular compounds such as polyacrylamide, polyvinyl alcohol, etc., which aggregate suspended substances together by charge adsorption and bridging.

Further, by discharging the upper clean water in the main tank 601 in an overflow manner, not only can a rapid drainage effect be achieved, but also the sediment in the lower layer can be prevented from being stirred in the drainage process, so that a better solid-liquid separation effect can be achieved.

The height of the upper sealing slide seat 1004 is higher than the top of the servo motor 1009, and as the height of the upper sealing slide seat 1004 is higher than the top of the servo motor 1009, even if the overflow slide seat 1003 is completely immersed in water, the upper clean water in the main box body 601 can be prevented from overflowing through the top of the overflow slide seat 1003, and a certain protection effect can be further achieved on the servo motor 1009; since the front ends of the lower sealing slider 1002, the overflow slider 1003 and the upper sealing slider 1004 are closely attached to the rear end surface of the main tank 601, a better sealing effect can be achieved, preventing leakage of the water in the main tank 601.

As shown in fig. 1-4, the bottom of the bottom supporting frame 1 is fixedly connected with a material guiding frame 11 located below the flocculation tank 6, the material guiding frame 11 is communicated with a blanking hole 103, and the material guiding frame 11 can guide the sediment discharged from the flocculation tank 6, so that the sediment can be accurately poured into a material receiving hopper right below the blanking hole 103, and the sediment is prevented from overflowing all around during discharging.

The working principle of this embodiment is as follows, sewage to be treated is sent into the water inlet pipe 3 through a pipeline, meanwhile, the unidirectional electromagnetic valve 405 is automatically opened, and the flocculant in the medicine storage tank 402 is injected into the water inlet pipe 3 through the administration pipe 404, so that the flocculant is uniformly doped into sewage flowing in the water inlet pipe 3;

then, sewage enters the spiral mixing mechanism 5 through the water inlet pipe 3, and when the sewage enters the mixing pipe 501, as the spiral auger blade 502 is arranged in the mixing pipe 501, the spiral auger blade 502 can play a role in stirring and mixing the flowing sewage when the sewage passes through, so that the sewage can be further and fully mixed with the flocculant;

after sewage and flocculating agent are fully mixed, the sewage flows into the main tank body 601 through the drainage tube 7, the round hole and the water injection tube 8 and is continuously gathered in the main tank body 601, after the main tank body 601 is filled with sewage, the sewage is left for a period of time, and flocculates in the sewage can slowly precipitate in the main tank body 601;

when the sewage in the main tank body 601 is settled, the flocculate is settled at the bottom, the clean water is positioned at the upper layer, at the moment, the servo motor 1009 can be started, the driving gear 1011 is driven by the output shaft of the servo motor 1009 to synchronously rotate, and as the driving gear 1011 is meshed with the fixed rack 1010, the driving gear 1011 can drive the overflow slide carriage 1003 to slide between the two guide slide rails 1001, the overflow slide carriage 1003 slowly moves down to the lower part of the water surface in the downward moving process, at the moment, the clean water at the upper layer flows out outwards through the overflow hole 1005, the rear end of the overflow slide carriage 1003 is provided with a drainage connector 1008 which can be used for connecting a drainage pipeline, so that the clean water can be introduced into a designated reservoir through the drainage pipeline to be collected in a concentrated manner;

after the upper clean water is discharged, the piston rod of the second hydraulic cylinder 909 can be controlled to start to shrink, so that the bottom support of the sealing discharge plate 902 is slowly lost, after the supporting baffle 910 is withdrawn, the sealing discharge plate 902 can be quickly and automatically sagged and opened under the action of gravity, the sediment accumulated in the bottom of the main tank 601 can also automatically fall down, and the sediment is quickly discharged through the discharge hole 605, at this time, the sediment discharged in the flocculation tank 6 can be guided by the material guiding frame 11, so that the sediment can be accurately poured into the material collecting hopper under the blanking hole 103, and the sediment is prevented from overflowing everywhere during discharging.
