Description
Technical Field
[0001] The utility model relates to the technical field of sewage treatment, in particular to a rotary fine grille which is convenient to clean. Background Technique
[0002] The rotary fine grille is a special water treatment equipment that can continuously and automatically intercept and remove various shaped sundries in the fluid, and can be widely used in urban sewage treatment, the water supply industry, and the inlet of power plants. At the same time, it can also be used as a pre-stage screening equipment in the wastewater treatment processes of industries such as textile, food processing, papermaking, and leather. It is one of the most advanced solid-liquid screening equipments in China. The rotary grille cleaner is widely used in domestic sewage treatment. At present, most domestic sewage treatment plants use reverse rake fine grilles, which have limited slag removal effect, high maintenance difficulty, and high maintenance costs. The function of the fine grille in the sewage treatment plant is similar to that of the coarse grille, both of which intercept suspended impurities in the sewage, but there is a difference in thickness between the two. The spacing between the bars of the coarse grille is between 10 and 20 mm, and the fine grille is between 5 and 10 mm. The fine grille with a spacing of about 5 mm has the ability to remove finer sundries in the sewage, so that the finer floating impurities in the sewage can be effectively intercepted by the fine grille. Since the fine grille intercepts finer floating impurities, the characteristics of these impurities themselves also cause some problems in the operation of the fine grille. The most common problem is that the quality of the fine impurities is relatively light and it is not easy to fall off the fine grille.
[0003] When the existing rotary fine grille is used to clean sewage, it cannot filter out fine impurities, and cannot play a greater role in sewage filtration. Moreover, it cannot be lifted at an angle, which limits the single slope and causes the device to be unusable in some cases.
[0004] In view of this, in response to this technical problem, the present application proposes a rotary fine grille which is convenient to clean. Content of the Utility Model
