Description

A sedimentation tank for sewage treatment

Technical Field

The utility model relates to the technical field of sewage treatment, in particular to a sedimentation tank for sewage treatment.

Background Art

Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, catering, etc., and is increasingly entering the daily lives of ordinary people.

For example, publication number CN220142828U discloses a sedimentation tank for sewage treatment, which belongs to the technical field of sewage treatment, and comprises a sedimentation tank body and two groups of support rods installed on the left and right sides of the sedimentation tank body, wherein each group of support rods has two members; the sedimentation tank for sewage treatment, by arranging a scraper and a filter screen, utilizes the function of installing a drain frame and an installing frame to fix the filter screen above the sedimentation tank body, so that when sewage is put into the sedimentation tank body, impurities in the sewage are filtered onto the filter screen through the double-layer filtration of the filter screen and the filtration of the installing drain frame, and the motor drives the reciprocating screw rod to rotate, drives the scraper to move, and pushes the filtered material of the filter screen to avoid the filtered material clogging the filter screen, and then the clean water flows to the bottom of the sedimentation tank body, and the water is discharged through the function of the drain pipe, thereby avoiding the sediment and water from mixing again in the process of discharging the water, thereby improving the work efficiency.

When the device is in use, the sewage is filtered through the double-layer filtration of the filter screen and the filtration of the installed filter frame to filter the impurities in the sewage onto the filter screen, and then scraped off by the scraper. However, the sludge and particulate matter in the sewage will inevitably clog the filter screen, thereby affecting the filtering effect. Therefore, a sedimentation tank for sewage treatment is proposed to solve the above problem.

The first motor 801 is started. Under the transmission effect of the second pulley 802, the transmission belt 803 and the first pulley 504, the first motor 801 drives the rotating shaft 501 to rotate synchronously. The rotating shaft 501 drives the rotating roller 502 to rotate synchronously, so that the conveyor belt 503 drives the silt layer on the top thereof to move toward the silt outlet 14.

The filter screen 132 located on the left side of the upper water outlet pipe 11 and the lower water outlet pipe 12 is slidably connected in the placement frame 131.

The filter screen 132 blocks part of the particle clusters suspended in the sewage on its left side, preventing the clusters suspended in the sewage from being discharged from the upper outlet pipe 11 .

Working principle:

Step 1: The sewage with flocculant added flows into the tank body 1 through the input pipe 2, and the upper outlet pipe 11 is opened. Under the action of the flocculant, the suspended particles in the sewage gather into larger clusters and deposit on the top of the conveyor belt 503 to form a sludge layer, and then the sewage is discharged through the upper outlet pipe 11. During this process, the baffle 3 makes the sewage flowing out of the input pipe 2 flow to both sides thereof to prevent the sewage from dispersing the sludge layer deposited on the top of the conveyor belt 503. The filter screen 132 blocks part of the particle clusters suspended in the sewage on its left side to prevent the particle clusters suspended in the sewage from being discharged from the upper outlet pipe 11.

Step 2: When the sludge layer on the top of the conveyor belt 503 reaches a certain thickness, the sewage is stopped from entering the tank body 1 through the input pipe 2, and the lower outlet pipe 12 is opened to discharge most of the sewage in the tank body 1 through the lower outlet pipe 12;

Step 3: Open the output pipe 901 and start the second motor 101 at the same time. When the second motor 101 drives the auger 102 to operate normally, start the first motor 801. Under the transmission effect of the second pulley 802, the transmission belt 803 and the first pulley 504, the first motor 801 then drives the rotating shaft 501 to rotate synchronously. The rotating shaft 501 drives the rotating roller 502 to rotate synchronously, so that the conveyor belt 503 drives the silt layer on the top thereof to move toward the silt outlet 14. During this process, the scraper plate 7 scrapes up the silt layer on the top of the transmission belt 803 and guides the silt layer into the rectangular shell 9. The silt introduced into the rectangular shell 9 is driven by the rotating auger 102 to the vicinity of the output pipe 901, and the silt is finally discharged from the device through the output pipe 901.
