Description

Radial flow sedimentation tank

Technical Field

The utility model relates to the technical field of water treatment facilities, in particular to a radial flow sedimentation tank.

Background

The radial flow sedimentation tank is mainly used for separating mud from water in sewage and wastewater treatment and is divided into two types of central water inlet and peripheral water inlet. The water enters the tank from the center or the periphery of the tank, the sludge in the water is deposited at the bottom of the tank by gravity in the tank, and the residual water after deposition overflows along the peripheral surface of the deposition tank and enters the water outlet channel to be discharged. The sludge at the bottom of the tank is discharged by a sludge scraper, so that the sludge-water separation is realized. The mud scraper consists of a rotating shaft, a rotating arm and a mud scraping plate. The rotating arm and the scraping plate are both connected to a rotating shaft which is rotatably arranged in the center of the pool. The mud scraping plate is arranged at the bottom of the pool. When the rotating arm rotates around the rotating shaft to drive the rotating shaft to rotate, the scraper is driven to rotate in the circumferential direction of the pool bottom pressure pool, and sludge at the pool bottom is scraped to the sewage outlet.

The first end of the scum scraper blade is fixedly connected to the rotating shaft, and the barrel body is connected with the second end of the scum scraper blade.

Because certain floats and greasy dirt exist in water more or less, a great amount of algae can be generated on the water surface of the pond in summer under the irradiation of the sun, and scum is necessarily formed on the water surface in the operation of the radial sedimentation pond. The existing radial flow sedimentation tank adopts the structure that a scum scraper is arranged on a rotating shaft of a mud scraper, and the scum scraper can rotate along with the rotating shaft of the mud scraper and move along the rotating shaft, so that the scum scraper keeps floating on the water surface. When the rotating shaft of the mud scraper rotates for a circle, the scum scraping plate rotates around the circumferential direction of the tank body for a circle to scrape scum and a small amount of sewage on the surface of the tank into a scum bucket preset on the periphery, the scum in the scum bucket automatically flows into a scum well by gravity, and then the scum is manually and periodically cleaned, so that the consumption of manpower and material resources is high. And the rotation speed of the mud scraper is extremely low, the scraping effect of the scum scraping plate is poor and is difficult to meet the requirement, the scum remained on the surface of the pool water still needs to be manually removed, the labor intensity of personnel is high, and the potential safety hazard is large.

Referring to fig. 1-5, the present embodiment provides a radial flow sedimentation tank, comprising: sedimentation tank body 1, staving 2, immersible pump 3 and filter bag. The sedimentation tank body 1 is a tank body of the radial sedimentation tank, an annular water inlet channel is formed in the periphery of the end face of the sedimentation tank body, and a water through hole is formed in the bottom of the water inlet channel, so that the water inlet channel is communicated with the inside of the tank body through the water through hole. An annular water outlet channel is arranged on the inner periphery of the water inlet channel.

The top end opening of the barrel body 2 is used for arranging the submersible pump 3 in the barrel body 2, so that after the water outlet of the submersible pump 3 is communicated with a pipeline, the pipeline extends out of the barrel body 2, and the water outlet of the submersible pump 3 is communicated with the outside of the barrel body 2.

After the filter bag is paved above the submersible pump 3, the barrel body 2 is floatingly arranged in the sedimentation tank body 1. The top end of the barrel body 2 is ensured to be 1-2cm lower than the water surface, so that the water can flow into the barrel body 2 all the time. Wherein the filter bag may be an 18 mesh filter bag.

So set up, the water that has dross such as algae, rubbish in the sedimentation tank body 1 gets into staving 2 from staving 2's top, filters the dross through the filter bag and flows around to immersible pump 3. At this time, the submersible pump 3 is started, and the filtered water can be discharged out of the barrel body 2. Like this, the water that has the dross in the sedimentation tank body 1 flows in and filters the dross by the filter bag from the top of staving 2 constantly, is taken staving 2 by immersible pump 3 again to constantly filter the dross in the water in the sedimentation tank body 1 and screen out. Under the suction effect of the submersible pump 3, scum on the water surface flows to the top end of the barrel body 2 along with the water and flows into the barrel body 2, so that the sieving effect is better, manual cleaning is not needed, labor is saved, slag discharging structures such as a slag discharging well are saved, and the operation of manually cleaning the slag discharging well is omitted.

When the scum reserve on the filter bag is too large, the filter bag is replaced, and the operation of replacing the filter bag is worth noting, so that the labor intensity is greatly reduced compared with manual secondary scum removal.

As an alternative embodiment, further comprising: a flushing pipe 4 and a shower nozzle 5. The flushing pipe 4 is positioned above the water outlet channel of the sedimentation tank body 1. The spray head 5 is a spray gun and is communicated with the flushing pipeline 4, so that the spray head 5 is positioned above the water outlet channel of the sedimentation tank body 1. When water flows into the flushing pipe 4, water can be sprayed out from the spray head 5 to the inner wall of the water outlet channel.

The barrel body 2 is provided with a connecting pipeline penetrating through the side wall of the barrel body 2, the water outlet of the submersible pump 3 is communicated with the inlet of the connecting pipeline, and the outlet of the connecting pipeline is communicated with the flushing pipeline 4 through a hose 13. Thus, when the submersible pump 3 is activated, water enters the flushing pipe 4 through the hose 13 and is ejected from the nozzle 5 onto the inner wall of the water outlet channel. Therefore, the inner wall of the water outlet canal is washed, algae attached to the inner wall of the water outlet canal is washed away, and the algae is prevented from affecting the water quality and the look and feel.

In some embodiments, the number of the spray heads 5 is ten, the ten spray heads are communicated with one another and are arranged on the flushing pipeline 4, and the ten spray heads can spray water to the inner wall of the water outlet channel of the sedimentation tank body 1, so that the flushing effect is better.

The side walls on two sides of the barrel body 2 are respectively fixedly provided with a buoyancy tank 10. Wherein the buoyancy tank 10 is made of HDPE, namely high-density polyethylene. The buoyancy tank 10 is hollow and provided with a filler. After the barrel body 2 and the buoyancy tank 10 are placed in the water in the sedimentation tank body 1, the filler has a specified quality to ensure that the top end of the barrel body 2 is kept lower than the water surface by 1-2cm.

As an optional embodiment, the radial sedimentation tank further comprises: a mud scraper. The mud scraper is the usual clear mud device in the current radial-flow sedimentation tank, and it includes: a rotating shaft 6, a rotating arm 7, a roller 8, a mud scraper and a scum scraper 9. Wherein the rotating shaft 6 is rotatably arranged at the center of the bottom of the sedimentation tank body 1, and can rotate around the axis of the sedimentation tank body 1. The mud scraping plate is arranged on the bottom surface of the sedimentation tank body 1, and the first end of the mud scraping plate is fixedly connected to the side wall of the bottom end of the rotating shaft 6, so that the mud scraping plate is driven to rotate around the axis of the sedimentation tank body 1 when the rotating shaft 6 rotates, and then the mud scraping plate scrapes sediment on the bottom surface of the sedimentation tank body 1 to a sewage disposal channel.

The first end of the rotating arm 7 is fixedly connected to the side wall of the top end of the rotating shaft 6, the lower part of the second end of the rotating arm 7 is provided with a roller 8 in a rolling way, the top end of the sedimentation tank body 1 is provided with an annular roller path, and the roller 8 is arranged in the annular roller path in a rolling way.
