Technical field:
The present invention relates to the induction installation ensureing underflow pump pump drainage concentration of hydraulic mixture in a kind of plate and frame dewatering and coagulating integration dredging silt engineering regulating reservoir, be particularly useful for liquid levels concentration different, need pump drainage lower floor to be greater than the device of finite concentration mud.
Background technology:
At present, known underflow pump drainage is by the direct pump drainage of underflow pump, or adopts special strength of fluid sensor method to measure pump drainage after concentration of hydraulic mixture in advance.But the method cost is higher, and complicated operation, may by direct pump drainage to balancing reservoir when lower floor's concentration of hydraulic mixture is lower, thus cause that desilting efficiency data reduces, overall dewatering and coagulating system reasonably can not play effect.
Summary of the invention:
Complexity is measured constantly in order to overcome lower floor's concentration of hydraulic mixture, the concentration of hydraulic mixture of partial period pump drainage does not reach rational concentration range, plate and frame dewatering and coagulating integration sludge treatment technique effect can not the problem of maximum performance, the invention provides the induction installation that can ensure underflow pump pump drainage concentration of slurry in a kind of regulating reservoir, automatically trigger closing switch when mouth concentration of hydraulic mixture is not up to standard at the bottom of underflow pump, after regulating concentration of hydraulic mixture, open underflow pump pump drainage manually or automatically to balancing reservoir.This device can not only ensure to be all the mud of concentration up to standard from regulating reservoir pump drainage to the liquid balancing reservoir, and can improve the pump drainage efficiency of underflow pump, thus plays the maximum effect of dewatering and coagulating integration.
The technical solution adopted for the present invention to solve the technical problems is:
The induction installation of underflow pump pump drainage concentration of slurry is ensured in a kind of regulating reservoir, comprise ball float, reinforcing bar, touch switch, bracing frame, two buoyancy tanks, Chain block, laterals, it is characterized in that: bracing frame is welded into by a crossbeam and two root posts, two root posts are separately fixed on two buoyancy tanks, two buoyancy tanks are linked into an integrated entity by lateral and prevent rollover, Chain block one end hangs on crossbeam, the Chain block other end is connected with underflow pump, reinforcing bar passes from ball float upper and lower surfaces, the reinforcing bar below ball float is fixed a touch switch.
The present invention also comprises spacing steel plate, and spacing steel plate is arranged on 25cm place under touch switch, and spacing plate size is 20mm × 20mm.
Described ball float is formed by lightweight nonabsorbent material and cross steel plate combination, lightweight nonabsorbent material is made into square or cuboid, six faces of square or cuboid are fixed with cross Plate Welding respectively, vertical along square or cuboid central hole, aperture 10mm, and ball float can be suspended in 1.2g/cm
