Description
Technical field
The present invention relates to a kind of mud strand sucking pump for mud cleaning, particularly relate to a kind of modularization for mud in sewage treatment structure diving mud strand sucking pump.
Background technique
Because water quality and quantity change, equipment failure, operation management such as to be not good at the reason, siltation problem is more or less there will be in the structure of sewage treatment works, the mud of deposition not only makes the actual volume of structure reduce, and mud rotten after can have a strong impact on effluent quality, so the mud in structure regularly must be removed.
But the mud mobility in structure is very poor, containing sediment and fiber foreign material in mud, very easily wear and tear and block the flow passage components for removing mud, and the depth of water of sewage treatment structure is darker, needing dives into the water carries out silt displacement, and domestic existing sludge pump product is all difficult to be suitable for.The main cause causing existing sludge pump to be difficult to remove mud in sewage treatment structure has: 1, the impeller of existing sludge pump is positioned at pump case inside, mud is sucked the pump housing by the negative pressure that sludge pump produces by vane rotary, and the mobility of mud is very poor, be difficult to be inhaled into, so many slurry pump can only pumping slurries water, the mud for gravity compressed deposition cannot be removed at all; 2, the bearing arrangement of pump shaft has problem, and in order to install mechanical seal, the pump shaft at impeller place is all the cantilever structure grown very much, reduces the rigidity of axle, causes vane rotary not steady, easily occurs the problems such as pump shaft fracture, wearing and tearing.What 3, most sludge pump was equipped with is dry type motor, can not dive into the water, and the suction mud degree of depth is limited, and deep water can only adopt major axis drive or extended at the bottom of pond by suction inlet with flexible pipe.If drive with major axis, transmission efficiency is low, Energy Efficiency Ratio extreme difference; Extend at the bottom of pond according to flexible pipe by suction inlet, then the mobility due to mud is very poor, has a strong impact on sludge pump efficiency, even there will be only water suction and does not inhale the situation of mud.
The problem of mud is inhaled for solving diving, people have devised a kind of Double-case submersible sludge pump, this sludge pump adopts submersible motor and double-shell structure, although solve the problem of diving and wearing and tearing, but this sludge pump is when the mud that removing mobility is very poor, still there is the problem of inhaling mud weak effect, still there is bearing arrangement problem in this sludge pump simultaneously, easily occurs the phenomenon that pump shaft ruptures.Again because pump shaft and motor shaft are the same axis, when after pump shaft wearing and tearing, whole motor shaft all must scrap replacing, because the rotor of motor shaft and motor is sizable interference fit, extremely bothers so change motor shaft.
Summary of the invention
For the problems referred to above, the invention provides the modularization diving mud strand sucking pump that a kind of mud eliminating is effective, maintenance cost is low.
For achieving the above object, modularization diving mud strand sucking pump of the present invention, comprise mud strand sucking pump module and drive described mud to twist the submersible motor module of sucking pump module, wherein said mud strand sucking pump module comprises pump case, be arranged on the pump shaft in described pump case, described pump shaft is connected with impeller, the motor shaft of described submersible motor drives and connects described pump shaft, one end of described pump shaft extends to the outside of described pump case mud suction mouth, the end that described pump shaft extends to outside mud suction mouth is connected with reamer, described pump shaft is also provided with sliding bearing, the axle journal of described sliding bearing is arranged on the pump shaft between described reamer and described mud suction mouth, the bearing shell of described sliding bearing is connected with described pump case by connecting tendon.
Further, described impeller is semi-open type three road non-clogging impeller, and the blade of described impeller is single-curvature blade.
Particularly, described reamer is have the mace structure reamer of some pawls or have the blade structure reamer of some blades.
Modularization diving mud strand sucking pump of the present invention, described submersible motor module and described mud are twisted sucking pump module and carries out independent setting, the motor shaft of described submersible motor module is driven and connects the pump shaft that described mud twists sucking pump module, reamer and sliding bearing is connected by extending on the pump shaft outside mud suction mouth, make the present invention compared with prior art, have the following advantages:
1, the present invention utilizes reamer fully to be mixed with water by mud in the rotation at suction inlet place, improves the mobile performance of mud, makes mud be easier to be inhaled into mud strand sucking pump, then is transported at a distance by suction booster;
2, the present invention has set up sliding bearing on pump shaft, and make the stress of pump shaft at impeller place become two ends freely supported structure by the cantilever structure of prior art, improve the rigidity of pump shaft, impeller operation is more steady;
3, complete machine is divided into submersible motor module and mud strand sucking pump module these two independently module by the present invention, and can keep in repair separately when breaking down, mutual noninterference, motor shaft and pump shaft are provided separately simultaneously, avoid the problem that pump shaft wearing and tearing must disassemble motor;
4, the present invention adopts the semi-open type three runner non-clogging impeller with single-curvature blade, and be not only shaped simple, low production cost compared with existing double shrouded wheel, and have better performance of anti-blockage and balance quality;
5, sliding bearing easy to wear in the present invention, reamer, impeller and pump case can be simple and quick replacing, reduce cost of equipment maintenance.
