Spiral Filter Press Trash Grille Machine

Abstract

The invention relates to the technical field of wastewater treatment equipment, in particular to a spiral pressure filtration type drain grating machine. The spiral pressure filtration type drain grating machine comprises a rotating shaft, a shell and a frame, wherein the shell is mounted on the frame, and the rotating shaft is mounted in the shell through bearing seats and is driven to rotate by a slowdown motor. A feeding bin is arranged above one end of the shell, a filter residue outlet is formed below the other end of the shell, a plurality of drain holes are formed below the shell, a first spiral blade, a second spiral blade, a third spiral blade and a fourth spiral blade are sequentially mounted on the rotating shaft from the feeding bin end, the pitch ratio of the first spiral blade to the second spiral blade to the third spiral blade to the fourth spiral blade is 3 to 2 to 1 to 1, and the length ratio of the first spiral blade to the second spiral blade to the third spiral blade to the fourth spiral blade is 16 to 15 to 4 to 1. The spiral pressure filtration type drain grating machine has the advantages of simple structure, little routine maintenance, thorough solid and liquid separation, low energy consumption and the like.

Description

technical field

[0001] The invention relates to the technical field of sewage treatment equipment, in particular to a spiral filter press type pollution control grid machine. Background technique

[0002] Urban sewage treatment is one of the important infrastructures of a city. Its development level directly affects the health and quality of life of urban residents, and is of great significance to the improvement of urban investment environment and the sustainable development of social economy.

[0003] The grid machine is a solid-liquid separation equipment, which can separate solid impurities, particles and other substances in the liquid from the liquid medium. According to the size of the grid mesh, the particle size and size of the separated solid material can be effectively controlled. , so as to ensure the operation index of liquid medium. The grille machine is also widely used, involving sewage treatment plants, water plants, pumping stations, power plant water inlet...
