Description

Sedimentation tank with sealing device

Technical Field

The utility model relates to a sedimentation tank especially relates to a sedimentation tank with sealing device. Belongs to the field of water treatment devices.

Background

At present, more and more sewage treatment plants require to cover deodorization, and the circular sedimentation tank of great diameter is covered and is covered comparatively difficultly, the reason is that the central point of sedimentation tank is mud scraper drive arrangement, can't set up the support column, and the apron roof beam span is big.

For example, CN10103908805A discloses a center drive mud scraper, which is disposed in a settling pond having a center column, and comprises a driving device and a mud scraping arm, wherein the driving device is connected above the center column through a fixed support; however, since the driving device is arranged at the central position, the supporting column cannot be arranged at the central position, so that the covering and sealing of the circular sedimentation tank with a larger diameter are difficult.

Therefore, most circular sedimentation tanks are provided with heightened covers by reverse hanging membranes, for example, CN104032825A discloses a fixed reverse hanging membrane sewage tank sealing unit which comprises a bracket and a reverse hanging membrane; the periphery of the sealing unit extends upwards to form a support, the support is constructed into a frame structure, a reverse hanging film is hung below the support, the middle of the reverse hanging film protrudes, and the periphery of the reverse hanging film sags downwards in an arc shape to form an integral arc-shaped structure. However, the film surface of the reverse hanging film is composed of an anti-corrosion coating base cloth and the like, is relatively fragile, and can not scratch the film cloth in a large area by sharp foreign matters; still other sedimentation basins have a relatively strong corrosion to the surrounding environment, and have a relatively high corrosion to the support around the anti-hanging membrane, which results in a short service life of the sealing unit. And the reverse hanging membrane needs to be cleaned and replaced, and the deodorization space is larger than that of the sealing unit with a cover, so that the sealing unit is high in operation cost and cannot be widely used in the market.

In order to achieve the above object, the utility model provides a sedimentation tank with sealing device, including the cell body, its characterized in that: the center of cell body is provided with the support column, the top of support column is provided with the apron roof beam be provided with the apron on the apron roof beam, the bottom cover of support column is equipped with central rotary device, the solid cover of central rotary device has the round pin fluted disc outward, the round pin fluted disc passes through the drive of transfer line gear and rotates around the support column, the last arm of scraping that is provided with of central rotary device, the downside of scraping the arm distributes and has scrapes mud device, and the upside is provided with the skimming device.

Set up the support column in cell body center and be used for supporting apron roof beam and apron to setting up the mud scraping device on the support column, having solved present sedimentation tank and can't adding the problem of establishing the apron owing to set up central mud scraping mechanism.

In the scheme, the method comprises the following steps: and a flow stabilizing cylinder is further sleeved on the supporting column and is positioned below the cover plate beam. The flow stabilizing cylinder can play a role in stabilizing flow.

In the scheme, the method comprises the following steps: the inner wall upper portion of cell body is provided with the round and goes out the basin, is close to it still is provided with except that the sediment fill to go out the basin, dross in the cell body passes through skimming device skims extremely remove the sediment fill, remove the dross in the sediment fill and discharge through dross removal mechanism again.

In the scheme, the method comprises the following steps: and a water retaining weir plate is arranged at the top end of the water outlet groove, and water in the pool body turns over the water retaining weir plate and enters the water outlet groove.

In the scheme, the method comprises the following steps: the top end of the side wall of the water outlet groove close to the center of the pool body is provided with a circle of slag baffle plate for preventing scum from entering the water outlet groove.

In the scheme, the method comprises the following steps: the skimming device comprises a skimming plate, and the skimming plate is supported above the scraping arm through a support.

In the scheme, the method comprises the following steps: and a motor driving the transmission rod gear to rotate is arranged on the cover plate.

In the scheme, the method comprises the following steps: the center of the bottom of the pool body is provided with a sunken mud bucket, and the bottom of the pool body is gradually inclined downwards from the edge to the center. The inclined bottom of the tank is beneficial to the sludge scraping device to scrape sludge into the sludge bucket at the center of the sedimentation tank.

Since the technical scheme is used, the beneficial effects of the utility model are that: the utility model can realize the capping and sealing in the circular sedimentation tank with larger diameter, and solve the problem of collecting and processing the waste gas and odor in the large sewage treatment tank; and the anti-corrosion device has a good anti-corrosion effect, is lower in cost, long in service life and small in deodorization space compared with a reverse hanging film sealing device, and can be widely applied to the market.
