Filter and method for assembling a nozzle pipe of a filter

摘要

The filter includes: a structure with a C-shaped profile defining side walls and nozzle pipes, each connected to the structure. Each nozzle pipe has a longitudinal axis and an end; a plate connected over a border of the nozzle pipe end to close the nozzle pipe. The plate extends beyond the border. The end of the nozzle pipe is inserted between the side walls of the C-shaped profile. The plate is connected between the side walls of the C-shaped profile. A U-shaped pin defines a first and a second leg, wherein the first leg is inserted in holes of the side walls of the C-shaped profile. The first and the second leg rest on the nozzle pipe and embracing the nozzle pipe. The plate is at an angle (A) greater than 0° with a plane perpendicular to the longitudinal axis of the nozzle pipe. The second leg has a protrusion that rests against the plate.

主权项

1. A nozzle pipe assembly of a filter cleaning system comprising:
a structure comprising a C-shaped profile defining a central wall, first side wall and a second side wall, the first and second side walls extending divergently from the central wall; at least one nozzle pipe connected to the structure, the nozzle pipe having a longitudinal axis and an end; a plate connected to a border of the end of the nozzle pipe to close the end of the nozzle pipe, the plate extending beyond the border; the end of the nozzle pipe arranged between the diverging first side wall and the second side wall of the C-shaped profile with the plate being connected between the diverging first side wall and second side wall of the C-shaped profile at a plate angle greater than 0° with a plane perpendicular to the longitudinal axis of the nozzle pipe; a U-shaped pin defining a central part, a first leg and a second leg; the first leg arranged through a hole in the first side wall of the C-shaped profile; and the U-shaped pin is rotatable to arrange the second leg to abut the first side wall of the C-shaped profile with a protrusion from the second leg abutting the plate, with the first leg and the second leg converging to embrace the nozzle pipe.
