Description
Technical field
The present invention relates to the field of environment protection equipment of sewage disposal, especially a kind of rotary grate of radial-flow mud scraper revolves barrel structure.
Background technology
Existing radial-flow mud scraper operation principle as shown in Figure 1, sewage W flows into outwards radiation downwards in the body of pond from the guide shell 1 collecting mud sump 5 central authorities, mud in body bottom, pond sludge blanket 4 is progressively settled down at the bottom of pond under gravity, and collecting output by scraping mud or inhaling mud equipment, the clear water Q of pond body upper supernatant layer 2 overflows from the downflow weir of pond body periphery.Guide shell 1 is the cylindrical structure of border seal, upper lower open mouth, only plays the effect of water conservancy diversion, and in the body of pond, densification height H 1(refers to the height of dense mud) high, sewage is easy to spread to periphery, mud-water separation face 3 is high, and supernatant layer 2 is highly low, and therefore sludge condensation effect is poor.
Summary of the invention
The applicant, for the shortcoming such as above-mentioned existing radial-flow mud scraper sludge condensation effect is poor, provides a kind of rotary grate of radial-flow mud scraper rational in infrastructure to revolve barrel structure, thus can realize the Separation of Solid and Liquid of mud and supernatant efficiently.
The technical solution adopted in the present invention is as follows:
The rotary grate of radial-flow mud scraper revolves a barrel structure, and guide shell is made up of central upper portion cylinder and bottom rotating cylinder two parts, and central tube is the cylindrical structure of border seal, upper lower open mouth, and the delivery port of water inlet pipe stretches in central tube; Lower open mouth on rotating cylinder, sidewall offers grid gap, and is arranged on the mud-scraping frame of revolution operation, slowly turns round during work.
Further improvement as technique scheme: described central tube is arranged on the steady job bridge at body top, pond, is divided into internal layer central tube and outer central tube, and described rotating cylinder is divided into internal layer porous plate cylinder and outer grid cylinder.
The diameter of described outer central tube and grid cylinder is suitable, is about about 1/3 of collection mud sump diameter; About the diameter of internal layer central tube and porous plate cylinder is about the half of grid cylinder diameter.
Described grid cylinder is formed by being arranged in order the some guiding grizzly bars bending inwards 45 degree be welded on the retainer ring of outer ring, and the width of grid gap is generally at below 10mm.
Mud-scraping frame is provided with some vertical grizzly bars.
Beneficial effect of the present invention is as follows:
The present invention replaces conventional guide shell by adopting rotary grate cylinder, under the rotary steering effect and filtration of grid, the interface of the inner mud of grid cylinder is made to remain on a relatively high state, under the effect of internal turbulence, accelerate gathering and the flocculation of mud granule simultaneously, the mud height of flocculating concentrates at the bottom of pond, improves thickening efficiency; Parting liquid outwards flows out from grid gap, and in pond, the parting surface of mud and supernatant reduces, and densification is highly lower, and supernatant height increases, and effectively improves the effect of separation, and improves back segment Treatment of Sludge cost.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 2, guide shell of the present invention is made up of central upper portion cylinder and bottom rotating cylinder two parts, and central upper portion cylinder is arranged on the steady job bridge 6 at body top, pond, and the central tube of the present embodiment is divided into internal layer central tube 10 and outer central tube 11; Bottom rotating cylinder is arranged on the mud-scraping frame 7 of revolution operation, and the rotating cylinder of the present embodiment is divided into internal layer porous plate cylinder 13 and outer grid cylinder 12.Outer central tube 11 is suitable with the diameter of grid cylinder 12, much larger than existing draft tube diameter, is usually about about 1/3 of collection mud sump 5 diameter; About internal layer central tube 10 and the diameter of porous plate cylinder 13 are about the half of grid cylinder 12 diameter.Water inlet pipe 16 is fixed on service bridge 6, and delivery port stretches in internal layer central tube 10.Mud-scraping frame 7 is provided with some vertical grizzly bars 19, and mud-collecting slot scraper plate 14 is arranged at the bottom of pond, and discharges mud by discharge pipeline 15.
Internal layer central tube 10 is similar to existing guide shell structure to outer central tube 11, is the cylindrical structure of border seal, upper lower open mouth.Lower open mouth on porous plate cylinder 13, sidewall adopts porous plate to surround, and the diameter of perforate is generally Φ 150mm.Lower open mouth on grid cylinder 12, as shown in Figure 3, Figure 4, grid cylinder 12 is formed by being arranged in order the some guiding grizzly bars 18 bending inwards 45 degree be welded on the retainer ring of outer ring, and the width of grid gap 17 is generally at below 10mm.
During actual motion, see Fig. 5, sewage W enters in internal layer central tube 10 from water inlet pipe 16, and first flow into below porous plate cylinder 13 in, and by the bottom of cylinder or tube wall opening enter grid cylinder 12.The newel 9 that porous plate cylinder 13, grid cylinder 12 drive with drive unit 8, mud-scraping frame 7 slowly rotate, direction of rotation R(is see Fig. 4) contrary with grizzly bar 18 warp direction, in rotary course, the inner side current of grizzly bar 18 pairs of grid cylinders 12 of warpage play certain barrier effect.Sewage between internal layer porous plate cylinder 13 and outer grid cylinder 12 in B region (see Fig. 3), existing from the top down, the radial radiation current of from-inner-to-outer, also there is the tangential rotary water current being stopped backflow by grizzly bar 18 simultaneously, therefore in this region, current are turbulent condition, suspended sludge particle is easily gathered into thicker particle or floccule when colliding with each other, thus accelerate precipitation, now the sludge interface of grid cylinder 12 inside remains on a relatively high state, and the mud being beneficial to flocculating in cylinder is directly settled down to the pool bottom sludge layer 4 of grid cylinder 12 bottom; Parting liquid clear water Q is then outwards flowed out by grid gap 17, enter the supernatant layer 2 on body top, pond, because mud focuses mostly at the interior zone of grid cylinder 12, thus the height of the parting surface 3 in the body of grid cylinder 12 outside pond is significantly reduced, thus densification height H 2 is lower, add the height of supernatant layer 2.The vertical grizzly bar 19 that mud-scraping frame 7 is arranged accelerates the sludge settling speed in the body of pond further.
Central tube and rotating cylinder are all provided with interior outer double-layer structure in the present embodiment, have good separating effect, can certainly omit the setting of inner core, directly arrange central tube and the grid cylinder of individual layer, thus simplify structure, reduce costs.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention is see claim, and when without prejudice to spirit of the present invention, the present invention can do any type of amendment.
