Filtration tank with flushing cover

Abstract

The invention relates to a filtration tank with a flushing cover. The filtration tank with the flushing cover comprises a filtration tank body, wherein a filtration bed is arranged at the bottom of the filtration tank body; a support layer is arranged at the lower end of the filtration bed; a triangular lapped water distribution plate is arranged at the lower end of the support layer; a water collection area is arranged under the triangular lapped water distribution plate; a cover body is arranged at the upper end of the water collection area; a washing siphon pipe is arranged on the cover body; a water seal cylinder is arranged at the lower end of the washing siphon pipe and arranged in a drainage channel; the cover body is connected with a truss vehicle which is arranged on the filtration tank body. The filtration tank with the flushing cover is convenient to use, simple to act, strong in periodicity, reliable to work, flexible and stable in action, good in sealing effect, small in abrasion, long in service life, convenient to maintain, short in construction period, simple to manage, small in maintenance workload and relatively low in manufacture cost; the production capacity is obviously improved; a large amount of construction investment is saved.

Description

technical field [0001] The invention relates to a filter tank with a flushing hood. Background technique [0002] The mobile hood filter is a filter composed of many filter grids. It adopts a small resistance water distribution system and uses a movable flushing cover to wash each filter grid in turn. The mobile hood filter is suitable for large and medium-sized water plants. The pool is shallow in depth, simple in structure and low in cost. [0003] The existing mobile hood has a large maintenance workload, and the sealing requirements between the cover body and the top of the partition wall are high. The sealing effect of the practical mobile hood filter is poor, and the normal use of the mobile hood filter cannot be guaranteed. The action is simple and the periodicity is strong. ,, Reliable work, flexible and stable action, good sealing effect, less wear, long life, convenient maintenance, short construction period, significantly improved production capacity, saving a lo...
