Problems solved by technology
The current drum grid mostly adopts the cross-shaped grill cylinder with ring grill and longitudinal ribs. The ring grill acts as a slag retainer and the longitudinal ribs serve as support. It is easy to encounter fiber dirt entanglement during work, which cannot be cleaned effectively, which seriously affects the water passing rate and removal rate. Pollution efficiency, and the current drum grille cylinder is welded on the upper and lower connecting rings and cannot be disassembled, causing great trouble to equipment operation and maintenance

The invention relates to a rotary drum grating cylinder. The grating cylinder comprises a lower connecting ring, an upper connecting ring, a pore plate grating cylinder, supporting steel tubes and material guiding blades, the pore plate grating cylinder is composed of a plurality of molding pore plates, and is respectively linked and fixed to the upper connecting ring and the lower connecting ring through fasteners, the upper connecting ring and the lower connecting ring are respectively fixed and linked to the supporting steel tubes through bolts, and the material guiding blades are respectively welded on the pore plate grating cylinder. The rotary drum grating cylinder has the advantages of simple structure, improvement of the water passing rate, reduction of residue entrainment, convenient mounting and dismounting, convenient maintenance and long service life, and mainly solves the residue entrainment problem to prevent winding of dirt to grating cylinder grids in order to further prevent reduction of the water passing rate in the grating running process.
Description
technical field [0001] The invention relates to a waste water pretreatment device, in particular to a drum grid cylinder. Background technique [0002] The rotary drum screen integrates sewage interception, lifting and pressing, and the zero slag leakage rate makes this type of product widely used in the market. The current drum grid mostly adopts the cross-shaped grill cylinder with ring grill and longitudinal ribs. The ring grill acts as a slag retainer and the longitudinal ribs serve as support. It is easy to encounter fiber dirt entanglement during work, which cannot be cleaned effectively, which seriously affects the water passing rate and removal rate. Pollution efficiency, and the current drum grille cylinder is welded on the upper and lower connecting rings, and cannot be disassembled, which causes great trouble to the operation and maintenance of the equipment. Contents of the invention [0003] In order to solve the above problems, the present invention provides...
