Novel energy-conserving waterpower grid maker
Technical field
The utility model relates to decontamination apparatus technical field, especially a kind of water treatment place being applied to the large discharge such as municipal sewage treatment, tap water intake, all kinds of pumping plants, for the protection of the novel energy-conserving waterpower grid maker of water pump and impeller.
Background technology
Municipal sewage treatment utilizes various facilities and equipment and Technology exactly, and pollution substance contained in sewage is separated removal from water, and make the Substance Transformation be harmful to be harmless material, useful material, water is purified, and resource is fully used.Municipal sewage plant's technique has coagulation, second-stage treatment and advanced treatment at present still in widespread use, but no matter which kind for the treatment of process, be all have to pass through sewage disinfection treatment.Preprocessing process, with regard to removing with regard to pollutent, may not play a crucial role, but pre-treatment is then vital for the normal operation of whole sewage work.Once had data statistics, the sewage work of more than 60% has had a strong impact on the running of subsequent processes due to preprocessing process existing problems.Therefore the lectotype selection of preprocessing process should cause enough attention with maintenance.Mostly traditional grid maker is inclined screen-type or uses plane grizzly bar, cannot realize automatic slag removal, needs carry out artificial scarfing cinder or install automatic slag remover.Wherein artificial scarfing cinder sanitary condition is poor, head loss large, and efficiency comparison is low, and poor continuity, and installs automatic slag remover and add equipment cost input, and energy consumption also increases thereupon.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provides a kind of structure simple, the novel energy-conserving waterpower grid maker that scavenging effect is good.
The utility model solves the technical scheme that its technical problem adopts: a kind of novel energy-conserving waterpower grid maker, be installed between the water-in of sewage pretreatment tank and water outlet, comprise the frame be obliquely installed, frame bottom is provided with the jockey sprocket be located at the bottom of sewage pretreatment tank pond, frame top is provided with driving chain wheel, is provided with the closed pivotal haulage chain rotated around it between jockey sprocket and driving chain wheel; Described haulage chain is provided with many rooted teeth rake axle, tooth harrow axle is arranged with a plurality of bidentate tooth harrow; Be provided with drive unit above described frame, drive unit is connected with driving chain wheel by belt, and haulage chain is connected with overload device; Described water-in pool wall is provided with the second liquidometer, and water outlet pool wall is provided with the first liquidometer, and the second liquidometer is all connected with PLC control cabinet with the first liquidometer; Described frame Lower Half is provided with the grizzly bar of interception dirt, and grizzly bar is positioned near water-in side.It is stuck that closed revolution haulage chain can prevent foreign material from entering haulage chain, ensures to operate steadily reliably.
Further, described grizzly bar bottom is provided with dash rubber.
Further, described frame is provided with at sludge outlet place and blocks dirty baffle plate, block the mud box being provided with below dirty baffle plate and collecting mud.
Further, the angle between described frame and horizontal plane is 60 ~ 85 °.
Further, described bidentate tooth harrow comprises the open holes being installed on tooth harrow axle, and open holes both sides are one-body molded two rake teeths, and the angle between two rake teeths is 100 ~ 140 °.A rake teeth of bidentate tooth harrow inserts in grizzly bar and drags for action clearly, and the gesture that another rake teeth then forms encirclement makes foreign material difficult drop-off, so it is effective to remove contamination.
The beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, easy to operate, is provided with bidentate tooth harrow and improves effect of removing contamination; Be provided with overload device protective grille machine, extend the work-ing life of grid maker; Be provided with the second liquidometer, the first liquidometer and PLC control cabinet, automatically control grid maker work and run, level of automation is high.

Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
Novel energy-conserving waterpower grid maker as Figure 1-3, be installed between the water-in 14 of sewage pretreatment tank and water outlet 15, comprise the frame 1 be obliquely installed, frame 1 bottom is provided with the jockey sprocket 4 be located at the bottom of sewage pretreatment tank pond, frame 1 top is provided with driving chain wheel 6, is provided with the closed pivotal haulage chain 3 rotated around it between jockey sprocket 4 and driving chain wheel 6; Haulage chain 3 is provided with many rooted teeth rake axle, tooth harrow axle is arranged with a plurality of bidentate tooth harrow 2; Be provided with drive unit 7 above frame 1, drive unit 7 is connected with driving chain wheel 6 by belt, and haulage chain 3 is connected with overload device 8; Water-in 14 pool wall is provided with the second liquidometer 12, and water outlet 15 pool wall is provided with the first liquidometer 11, second liquidometer 12 and is all connected with PLC control cabinet 13 with the first liquidometer 11; Frame 1 Lower Half is provided with the grizzly bar 16 of interception dirt, and grizzly bar 16 is positioned near water-in side.
Grizzly bar 16 bottom is provided with dash rubber 5; Frame 1 is provided with at sludge outlet place and blocks dirty baffle plate 9, block the mud box 10 being provided with below dirty baffle plate 9 and collecting mud; Angle between frame 1 and horizontal plane is 80 °; Bidentate tooth harrow 2 comprises the open holes 21 being installed on tooth harrow axle, and open holes 21 both sides are one-body molded has the angle between two rake teeths, 22, two rake teeths 22 to be 125 °.
During work, under the driving of drive unit 7, haulage chain 3 from bottom to top does turning motion, haulage chain 3 is arranged at intervals with many rooted teeth rake axle, tooth harrow axle is arranged with a plurality of bidentate tooth harrow 2; When the bidentate tooth harrow 2 on haulage chain 3 runs to the upstream face of grizzly bar 16 under water, namely bidentate tooth harrow 2 inserts in the gap of grizzly bar 16 and drags for action clearly, scrapes the foreign material that grizzly bar 16 retains on bidentate tooth harrow 2.When bidentate tooth harrow 2 runs to frame 1 top, bidentate tooth harrow 2 overturns, and foreign material are shed in mud box 10 by deadweight.
