Background technology
Grid sewage-removing machine is one of plant equipment of a kind of sewage disposal system indispensability.At present, the grid sewage-removing machine majority that existing sewage treatment plant is used is in the majority for the rake teeth type grid sewage-removing machine, under the driving of motor reducer, rake tooth chain carries out direction gyration against the current, when rake tooth chain runs to the top of equipment, due to the guiding of sheave and curved rail, make between every group of rake teeth to produce relatively moving from clearing, most solid matters fall by gravity.But due to wearing and tearing for a long time between rake teeth and rake teeth, finally make gap between rake teeth become large, thus can not be by the sewage cleaning thoroughly, and also the rake teeth ratio is easier to the hook slag, difficult drop-off, thus affected wastewater treatment efficiency.During work, the head sprocket that reductor drives on main shaft rotates, when fishing for excessive or overweight dirt, jam or overload phenomenon will occur, cause the chain of web plate chain both sides not parallel, thereby affected the normal operation of web plate chain, the service life of having reduced grid sewage-removing machine.
The utility model content
For above-mentioned defect; it is a kind of simple in structure that the purpose of this utility model is to provide; by clearing apparatus and flusher, the web plate chain is removed to residual dirt; offer some sieve screen apertures on web plate, make that to drag for slag thorough, good sewage processing effect; in while, in the course of the work overload occurring; disconnect by the tablet in torque protection device and inductive switch, thereby effectively protected reductor and web plate, a kind of web plate stairs like grate for removing solid substance greatly extended service life.
The technical scheme that the utility model adopts for this reason is: comprise skimming device, from sprocket wheel, frame, the web plate chain, flusher, clearing apparatus, head sprocket, reductor and footing pair, described frame is fixed on civil engineering by the footing pair, head sprocket is arranged on the frame upper end and drives by reductor, be arranged on the frame lower end from sprocket wheel, the web plate chain is socketed in head sprocket and from sprocket wheel, flusher is between the web plate chain and towards descending web plate chain, clearing apparatus is positioned at descending web plate chain upper end side, up web plate chain upper end is provided with torque protection device, skimming device is arranged on web plate chain lower end.
Described web plate chain comprises web plate, slag trap and chain, described web plate is slot type structure, the two ends of web plate are provided with baffle plate, the widthwise edge of web plate is provided with in-flanges, the web plate bottom surface is provided with some sieve screen apertures, the web plate two ends are fixed on the inner plate on chain by securing member, and chain link one end that the inner plate on chain and outer plate form is wide outward to be equated with other end inner width, between web plate and chain, is provided with slag trap.
Described torque protection device comprises rack-mounted inductive switch; be provided with tablet before inductive switch; tablet is arranged on pull bar; pull bar is fixed by swing arm; swing arm is arranged on reductor, and the pull bar tail end is provided with boss, and the pull bar tail end is positioned at cylindrical shell; be provided with some dish springs between cylindrical shell and boss, the cylindrical shell side is provided with turntable and is arranged on frame.
The utility model has the advantages that: the utility model is simple in structure; by clearing apparatus and flusher, the web plate chain is removed to residual dirt; offer some sieve screen apertures on web plate; make that to drag for slag thorough; good sewage processing effect, while in the course of the work overload occurring, disconnect by the tablet in torque protection device and inductive switch; thereby effectively protected reductor and web plate, effectively extended the service life of grid.
