Description

TECHNICAL FIELD

[0001] The utility model relates to sewage treatment technical field especially sewage treatment is with filter device. BACKGROUND

[0002] With the rapid development of industrialization and urbanization, sewage treatment has become a key link of environmental protection. In the sewage treatment process, filtration is one of the most important steps, which removes impurities, suspended solids and other pollutants in sewage, and thus improves water quality.

[0003] The patent with publication number CN222342235U discloses a filter device for sewage treatment. The device drives the driving roller through the first motor, and the driving roller cooperates with the driven roller to drive the filter screen transmission belt to run, thereby lifting the impurities filtered out by the filter screen transmission belt to the collecting hopper. The impurities in the collecting hopper then fall into the discharge pipe, and under the action of the second motor driving the spiral auger, the impurities are output, achieving the effect of active output of impurities. When the spiral auger outputs the impurities, it uses the gradually changing pitch to extrude the impurities, and cooperates with the filter screen hole to achieve the purpose of draining.

[0004] However, in actual use, the device involved in the patent still has some shortcomings. First, the bottom outer side of the filter screen transmission belt is provided with a baffle that fits and adapts to it, and the baffle is fixedly connected with the inner wall of the filter channel, aiming to shield the gap between the filter screen transmission belt and the bottom of the filter channel through the baffle, to prevent the impurities from flowing backward directly through the gap. However, at the same time, the friction between the baffle and the filter screen transmission belt will cause the surface of the transmission belt to wear out more severely. Second, the spiral auger does not uniformly collect and process the extruded impurities.

[0005] In view of the above situation, how to change the existing technology that the transmission belt is easy to wear and the collected impurities cannot be centrally processed has become a technical problem to be solved by those skilled in the art. UTILITY MODEL CONTENTS
