Description
Technical field
The utility model relates to the environmental protection equipment field, especially a kind of dredging tube flow regulator of self-priming suction dredge.
Background technology
Self-priming suction dredge is that city water factory, urban wastewater treatment firm sedimentation basin commonly used is inhaled mud equipment, and water inlet in the middle of adopting, peripheral effluent and spoil disposal utilize the self-priming spoil disposal of liquid level difference, have scum silica frost to scrape collection remover and overload protection arrangement.As shown in Figure 1, mainly formed by peripheral drive running gear 1, scum silica frost collection bucket 2, effluent trough 3, skimming rake 4, service bridge 5, center support 6, mud-collecting slot 7, dredging tube 8, scum board and parts such as water outlet weir plate 9, water inlet pipe 10 and skimmer device.During real work, service bridge 5 is to travel with 2m/min left and right sides linear velocity at Chi Ding in the axle center with center support 6 under the driving of peripheral drive running gear 1, makes circular motion slowly; Sewage from the water inlet pipe 10 at center, pond after the guide shell diffusion, flow out radially to periphery uniformly, be the mud of suspension at the bottom of post precipitation is deposited on the pond, supernatant is discharged outside the pond by effluent trough 3 by water outlet weir plate 9, the mud scraper plate is scraped collection mud to dredging tube 8 centers at the bottom of the pond, rely on pool inner water to press by mud-collecting slot 7, discharge pipeline and discharge outside the pond; Nearly liquid level place is provided with skimmer device, extends to skimming rake 4 by the center stabilizing feed well, and when service bridge 5 rotations, skimmer device is cast aside the scum silica frost on the liquid level to pond week by the center, pond, and by skimming rake 4 scum silica frost is scraped to scum silica frost collection bucket 2, and is discharged to outside the pond.
Inhaling in the mud process at suction dredge, need regulate the suction mudflow amount of dredging tube 8 according to the actual conditions needs, all is to hang down to regulate flow by interpolation rubber chock plug and adjusting plug head height above dredging tube 8 outlets at present.The lower end of screw mandrel is enclosed with the rubber chock plug, and screw mandrel top is meshed with feed screw nut on being fixed on service bridge 5, and when the rotary screw nut, the moving up and down of screw mandrel promotes or reduce moving up and down of rubber chock plug, thereby realizes inhaling the adjusting of mudflow amount.But because the rubber chock plug is located immediately at the top of dredging tube mouth, cause the water outlet loss of flood peak bigger, and the complicated cost of making of parts such as screw mandrel is higher, and need be equipped with at each dredging tube mouth, complex structure is difficult for maintaining, waste of material and less economical.
The utility model content
The applicant adopts the engagement of screw mandrel screw at the suction mudflow quantity regulating device of above-mentioned existing dredging tube, complex structure and cost height, shortcomings such as the loss of flood peak is big, a kind of dredging tube flow regulator of self-priming suction dredge rational in infrastructure is provided, thereby simplify the structure, reduced cost, and regulating effect is better.
The technical scheme that the utility model adopts is as follows:
A kind of dredging tube flow regulator of self-priming suction dredge is made up of inside and outside nested adjuster urceolus and adjuster inner core, and the flange of adjuster inner core is weldingly fixed on the bottom surface of mud-collecting slot, and is connected with the upper flanges of the mouth of pipe of dredging tube; The top of adjuster urceolus also is provided with the location annulus, is welded with thin bar along diametric(al), offers trapezoidal delivery port on its barrel, and tube bottom is provided with flange in the adjuster, offers the rectangle delivery port on the barrel, and the waist center line of assembling back two delivery ports overlaps; The location annulus of adjuster urceolus is connected to the upper orifice of adjuster inner core.
As further improvement in the technical proposal: the discharge area of described trapezoidal delivery port is about 1.2 times of rectangle delivery port discharge area.
Adjusting device is regulated by regulating handle, and regulating handle is made up of shank, bar portion and draw-in groove, and the A/F of U-shaped draw-in groove is corresponding with thin bar.
The beneficial effects of the utility model are as follows:
The utility model sets out the mouth of a river by the barrel at the adjuster inner/outer tube, and adjusts the discharge area at the mouth of a river by rotation, thereby reaches the flow of regulating the sludge water in the dredging tube, the purpose that the mudflow amount is inhaled in control.The utility model is simple in structure, and is easy to process, safeguards easily, with respect to chock plug formula adjusting device, need not screw mandrel, the compacting rubber stopper is first-class, when dredging tube stops up because of various reasons, can dismantle quickly and easily, reduces the workload of dredging pipeline greatly.
