Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment equipment, in particular to a novel screen machine for sewage treatment. Background Art

[0002] There are many types of existing sewage treatment equipment, among which the screen machine is used in large quantities. The main function of the screen machine is to salvage the solid impurities floating in the sewage, so as to achieve the effect of solid-liquid separation of the sewage. The existing screen machine is usually a rotary screen machine, which salvages floating objects through the rotary motion of the rake teeth. However, the defects of the screen machine are that its rake teeth are small and can only salvage small floating objects, and it is difficult to salvage larger floating objects. In addition, the salvage amount of the screen machine is small each time it rotates, so it takes a long time to salvage, which also consumes a lot of electricity.

[0003] According to a Chinese patent application number CN202320564872.5, a novel screen machine for sewage treatment is disclosed. The utility model is provided with fixed bars on the screen, a screen drum is rotatably provided above the screen and rotating bars are provided on the screen drum. Floating objects on the water surface are scooped out by the rotation of the rotating bars. In this way, more floating objects and larger volumes of floating objects can be scooped out at one time. Due to the large scooping amount, the device does not need to run for a long time, saving electricity costs. Unloading bars are provided on the fixed side columns to facilitate the unloading and collection of floating objects.

[0004] However, the above-mentioned screen machine still has certain shortcomings when in use: when the screen is used to salvage floating objects, some smaller impurities adhere to the surface of the screen and cannot fall off. Since the screen has no function of cleaning, the impurities will fall into the water when the screen enters the water again, resulting in unsatisfactory salvage effect. Utility Model Content
