Description

Sand remover {Sand remover}

The present invention relates to an acupuncture lifting device, and more particularly, to a sedimentation lifting device that is light in weight and strong in weather resistance, and is easy to install and maintain, as well as having a low failure and work delay.

Among the main facilities of water and sewage treatment plants, the sedimentation lifting device for removing foreign substances such as sand or water flowing in with water or sewage plays an important role as a primary and physical purification means.

That is, the sedimentation lifter is to scrape out the sand and other foreign matter accumulated in the bottom of the settlement land, which is a civil engineering structure in the form of a rectangular tank with a bucket to discharge to the outside of the settlement.

More specifically, by using the rotational force from the drive motor provided above the rectangular sedimentation tank, two rows of endless endless rows of these sprockets are rotated by rotating a plurality of shafts and sprockets mounted on each shaft in the width direction in the sedimentation tank. The plate and the plate coupled to these endless chains at regular intervals are moved in one direction, and the sand and the like accumulated on the bottom of the settling tank are scraped off and transferred to a separate collection container provided on one side of the settling tank.

The sand and other foreign matters accumulated on the bottom of the sedimentation tank, in particular, in the sewage treatment plant, are not limited to merely containing water, but usually contain a large amount of mucus dirt with odor.

On the other hand, the acupuncture lifting device having the above structure and function has the following problems.

First, since all the components of the acupuncture lifter are composed of metal, especially iron (Fe) as a main component such as a bucket, a chain and a sprocket, the weight of the acupuncture lifter is inevitably increased.

That is, the initial installation work is difficult, as well as maintenance after installation is not easy.

In addition, since the sand and other foreign matter, that is, the dirt is usually highly corrosive, the metal components constituting the sedimentation lifter are easily corroded.

In other words, by causing the premature aging of the sedimentation lifting device, the occurrence of failures and the resulting delay in work, as well as the problem of overlooking the aesthetics of the entire facility was never overlooked.

The present invention has been devised in view of such a conventional problem, and an object of the present invention is to provide a light weight and weather resistant sedimentation lifting device.
