An inner-rotating grille sealing connector

Abstract

The invention discloses a sealing connecting piece for inward-rotation type grating plates. The sealing connecting piece comprises one set of grating plates. The grating plates include a pair of upper supporting arm and lower supporting arm, wherein the upper supporting arm and the lower supporting arm are horizontally arranged in parallel. The two ends of the upper supporting arm and the two ends of the lower supporting arm are connected through fixing plates respectively. A filtering membrane plate is arranged between the upper supporting arm and the lower supporting arm. An upper sealing coupling piece is arranged at the upper end of the upper supporting arm, and a lower sealing coupling piece is arranged at the lower end of the lower supporting arm. The upper sealing coupling piece and the lower sealing coupling piece between the adjacent grating plates are connected in a staggered manner. A sealing strip is arranged between the upper sealing coupling piece and the lower sealing coupling piece. According to the sealing connecting piece for the inward-rotation type grating plates, the sealing effect during equipment operation can be effectively achieved, the grating plates cannot be blocked, the filtering efficiency is high, maintenance is reduced, and operation cost is reduced.

Description

technical field [0001] The invention relates to an accessory of sewage treatment equipment, in particular to an inner-rotating grid plate sealing connector. Background technique [0002] The gap between the grid plates of the existing internal rotation grille is large. During operation, the gap is much larger than the mesh of the membrane plate. The garbage originally filtered by the membrane plate leaks through the gap, which affects the filtering effect, and large garbage is easy to get stuck. In the gap, the equipment needs to be shut down for maintenance. Contents of the invention [0003] Purpose of the invention: Aiming at the deficiencies of the prior art, the present invention discloses an internally rotating grill plate sealing connector with good filtering effect and not easy to be blocked. [0004] Technical solution: The present invention discloses an inward-rotating grill plate sealing connector, which includes a set of grill plates, and the associated grill ...
