The drum type grille decontamination machine

Drum type grille decontamination machine is also called the fine grid filter or spiral grille machine, is a collection of fine grille decontamination machine, screw hoist and grid grid slag slag screw press in the integration of equipment.Grille piece press into drum barrier gate clearance basket, treated water inflows from before the gate basket, through the grating filter, flow to the pool, trapped on the grid, the grid slag when grid inside and outside the water level difference reaches a certain value, the installed on the central axis of the rotating harrow rotary clean-up, when slag removal harrow to dig the dirt set grid basket of vertex position (12 clock), began to discharge slag can (by weight drop slag discharge into the gate of the gate in slag tank);After then turn 150, by the slag removal tooth plate at the top of the gate basket of grid slag adhesion on tine automatic shaving, slag discharge into the gate slot.Grid slag by the drain screw conveyor to ascend, supremacy of squeezing period of pressing dehydration outbound, grid slag solid content of 35% - 45% DS.
Rotary drum grille:
Drum type screen machine is also called the fine grid filter or spiral grille machine, is a collection of fine grille decontamination machine, screw hoist and grid grid slag slag screw press in the integration of equipment.Is a process of urban sewage and industrial wastewater treatment will be floating in water in substance, sedimentation and separation of suspended material take out an ideal equipment, widely used in urban sewage, industrial wastewater treatment project of solid-liquid separation, cleaning, transfer, and the filter residue squeeze dewatering. 


Scope of application


Sewage water treatment equipment before treatment;


Factories, hospitals, residential area, water and drain impurities removal;


Mining, paper making, chemical fiber, textile, printing and dyeing and other industrial waste material separation;


Used for sewage treatment plant level after decontamination, in dregs and squeeze dehydration;


The decontamination of industrial wastewater treatment projects, in dregs and squeeze dehydration; 


The working principle of


Drum type screen machine made by press grille gate clearance drum grid basket, pending from gate the basket into water, through the grating filter, flow to the pool of exports, trapped on the grid, the grid slag when grid inside and outside the water level difference reaches a certain value, the installed on the central axis of the rotating harrow rotary clean-up, when slag removal harrow dig the sewage collection to the grid baskets of vertex position, began to discharge slag can (by weight drop slag discharge into the gate of the gate in slag tank);After each then turn 15 °, was gate basket at the top of the slag removal tooth plate of grid slag adhesion on tine automatic shaving, slag discharge into the gate slot.Grid slag by the drain screw conveyor to ascend, first department press period of pressing dehydration after discharging into the conveyor belt or truck outside.By squeezing the filter residue after dehydration, solid content of 25% - 25%, sinotrans to reduce cost and prevent secondary pollution, play an important role.


The main features
1, grille, and water to form 35 ° Angle, because the formation of the baffle, even if the thickness is less than the grille aperture many dirt can be separated;
2, grille, and equipped with a flushing device, scraper device, has self-purification function;
3, cylindrical structure than traditional make gratings over water flow, head loss is reduced, and the accumulation of grille before plane reduced;
4, all parts are made by stainless steel into contact with water, and through acid purification processing, of all the most civil sewage and industrial water, strong anticorrosion performance, long service life;
5, through the grid integration of salvage, transmission, compression processing, namely save area, also reduced the waste of the subsequent handling fees;
6, requires little maintenance, rotating point without refueling, drive gas few times
