Description
Technical field
The utility model relates to a kind ofly inhales the machinery sent for Lower tank slurry, belong to mechanical field.
Background technique
City inspection shaft sludge slurry, Sewage Plant settled sludge, the operating modes such as chemical plant, smelter, cesspool, accident groove all also exist the precipitating sludge slurry in low level pond, these sludge slurries are when entering next procedure process, all to promote to be delivered to down and process post together, but it is a difficult problem long-term in the industry that the lifting of the mud slip of this operating mode suction is sent, suitable transfer pump.Such as: if carried with dirty formula centrifugal pump of diving, because of a large amount of granular solids things meeting clogging impellers in mud, cause stuck, submerged pump does not have anti-corrosion function simultaneously, just cannot use the corrosivity mud in chemical plant; And for example, state mud slip if having the suction of the displacement pump of self-absorption function to serve with screw pump, rotor pump etc., owing to containing a large amount of silk, sheet and granular solid matter in this type of mud, be easy to stuck screw pump or rotor pump; For another example, if select the centrifugal Under Water Pumps of chemical industry and self-priming pump to inhale serve the slip stating low level pond, because of the restriction of Under Water Pumps concentration and the reason damage pump such as self-priming centrifugal pump impeller channel is narrow and small, ideal effect can not reached yet.Therefore, the settled sludge in a lot of Lower tank, inspection shaft, change Dung pond and sediment, can only draw cleaning with excavated by manual work.Because these sediments are all in the bottom of pond groove, often have biogas to gather, if cleaning personnel run into biogas gently, injure health, heavy then entail dangers to life, the report that the whole nation is dug slag because of lower cloaca, inspection shaft, Dung pond and got killed often occurs, and operate under these operating modes, environment is dirty smelly, and this work of operating conditions extreme difference is the mind pain that vast sanitationman is difficult to overcome for a long time.But not yet have up till now and be applicable to inhaling the conveying mechanism sending low level sludge slurry, slag.The utility model people once carried out the trial exploitation of this respect for a long time; such as attempt the sludge slurry carrying low level pond with direct acting bellowspump, membrane pump with pneumatic drive, sliding vane rotary pump isometric(al) pump; especially inhale when sending the corrosivity mud of the enterprises such as chemical industry hydrometallurgy; easily be corroded; also has the machinery of each industrial field slurry bodies such as current chemical industry, smelting, environmental protection; usually still to carry with centrifugal pump, the major defect of centrifugal pump slurry body is that efficiency is low, general 100m
3the transfer efficiency of the small flow shurry pump within/h only has about 30% ~ 50%, energy consumption is high especially, another shortcoming of centrifugal pump conveying slip is that the linear velocity of overcurrent slurry is large, generally to reach more than 20 meters per second, slip at a high speed produces erosion to the assembly of centrifugal shurry pump inner chamber, digs the wearing and tearing of cutter property, makes centrifugal shurry pump extremely short for working life.The post of general height abrasion, the leaching slurry delivery pump of such as zinc abstraction, the life-span only has 1 ~ 2 month.In slurry pipeline transport field, so far energy large size is not yet had to replace the product of centrifugal shurry pump, although market has small-sized plunger pump, diaphragm pump, peristaltic pump isometric(al) slurry delivery pump, but it is little owing to there is feed flow, without shortcomings such as anti-corrosive properties, at industrial field still without the value of large size large-scale popularization application.
In sum, no matter the slurry pipeline transport mechanical aspects in industrial field is that the suction of common slip is sent, the conveying of corrosivity slip or the suction of low level slip are sent, and all there is the improvement space of conveying equipment.The space promoted further is all had from aspects such as working life, utilization efficiency, cost-saving, using function.
Summary of the invention
