Description
Technical field
The present invention is that device is sent in the suction of a kind of environment-friendly type sludge pipeline conveying, relates to non-ox stream---Binghambody (Bingham) conveying technology.
Background technology
In reservoir, lake, river course, accumulate over a long period, gradually deposited more and more thicker mud layer, riverbed is improved.This not only reduces storage capacity, contaminated environment, affects traffic, and can make flooding in flood season, jeopardizes dyke, causes floods.In addition, class industry byproduct and discarded objects such as primary slime, municipal sludge, paper mill sludge, in all many-sides such as oil, chemical industry, mining, environmental protection, all relate to the Cemented filling being similar to the soft sticky material of mud character.Visible, sludge pipeline conveying equipment, has the wide market demand and application prospect widely.
Mud is non-newtonian fluid, is under the jurisdiction of the category of Bin Hamu (Bingham) body, when mud be in semisolid viscid with liquid-plastic state time, be difficult to realize feeding free from environmental pollution.By retrieving domestic and international patent document and relevant database, from the data searched out, the research of a lot of experts and scholars, in this technical field, has made positive contribution.Have also been made the research of some useful Theory and applications.The early-stage Study of this seminar, realizes the method and apparatus of soft sticky material remote pipe conveying.There is Chinese patent: a kind of pneumatic conveying of slurry method and system (93104552.5), skin covering of the surface drag reduction method and visco-plasticity transportation technology (200710126557.X), the defeated mud equipment (00247696.7) of environment-friendly type desilting, pipe-line transportation equipment for viscoplasticity materials (200720156216.2), efficiently solves many difficult problems of soft sticky material remote pipe conveying ".But, never capture this key technology of pollution-free feeding.
Economizing Natural Science Fund In The Light " research of visco-plasticity mud tubes conveying new method and mechanism " (M503164), " bury---visco-plasticity material pipe post stream conveying characteristic is studied " (Y505041), Hangzhou emphasis innovation fund " the defeated mud equipment of environment-friendly type desilting " (20051321B13), under the subsidy of Department of Education of Shanxi Province's emphasis science fund " research of Binghambody Cemented filling new method and the defeated mud equipment of environment-friendly type desilting " (20010430).On the basis of the early-stage Study of seminar, invent a kind of sludge pipeline suction and sent device.
Summary of the invention
The object of the invention is that a difficult problem is sent in the suction solving the conveying of environment-friendly type sludge pipeline, comprises shortening and inhales distance, prevents air intake, inhales and send conversion and raising to inhale the device sending speed.
Technical solution of the present invention comprises: working cylinder, reversal valve, suction nozzle, skin covering of the surface nozzle for liquid, feeding pipe, joint, sealing cover, it is characterized in that: J type reversal valve is placed in suction nozzle, one end is connected with feeding pipe through joint, and the other end commutates with a few working cylinder and is connected; Joint is interior, suction inlet is interior and periphery that is working cylinder mouth is respectively equipped with skin covering of the surface nozzle for liquid; Skin covering of the surface nozzle for liquid is connected with electromagnetic valve, measuring pump, skin covering of the surface liquid generator through pipeline.
Described working cylinder can adopt two or more, the piston alternate reciprocating motion in working cylinder, and a working cylinder is in pusher, and all the other working cylinder suctions, pusher working cylinder connects feeding pipe by J type reversal valve all the time.
Described skin covering of the surface nozzle for liquid connects with electromagnetic valve, measuring pump, skin covering of the surface liquid generator through pipeline, suction pass through meet obstructions larger in journey time, in good time ejection has the skin covering of the surface liquid of drag reduction and dehydration double action, overcome the viscosity of material, reduce the resistance that material enters working cylinder, improve suction and send efficiency.Skin covering of the surface liquid adopts different formulas according to different earth.
The gap of described sealing cover is full of light filler, in order to avoid air intake.
Advantage of the present invention
1. because several working cylinder is connected by J type reversal valve and joint with between feeding pipe, suction inlet is set in the front end of working cylinder mouth side, shortens the distance of suction inlet to working cylinder mouth, with the suction journey of material, effectively improve suction and send efficiency.
2. owing to being respectively equipped with skin covering of the surface pendular ring type jet pipe and nozzle with the periphery of working cylinder mouth in suction inlet.Pass through in journey in suction, occur that water content is less than the soil body of plastic limit, when the charging rate of suction inlet is slack-off.In good time ejection has the skin covering of the surface liquid of the double action of drag reduction lubrication and dewatering and coagulating, make between tube wall and earth, to be lined with one deck suspension film, the wall friction power of material is reduced, overcomes the viscosity of material, ensure that material enters working cylinder smoothly, and decreased the resistance that material enters working cylinder.Improve suction and send efficiency.Solve this crucial problem of pollution-free feeding.
3. be placed in material mouth because charging aperture is provided with J type valve, be provided with wear-resistant gasket with working cylinder connection place, ensured reliable conversion and the continus convergence of material.
4., because suction inlet is bell mouth shape, it is compacted that suction passes through the soil body in journey, adds appropriate skin covering of the surface liquid, decrease the suction of air to greatest extent.Rate is filled for raising play an important role.
5., because whole process adopts the Cemented filling of sealing, solve the secondary pollution problem in carrying.
The present invention is applicable to plastic state and flow regime, and the suction that namely natural moisture content is greater than the soil body of plastic limit is sent.Be not only applicable to municipal sludge clear, and purposes extremely is widely had in oil, chemical industry, mining, water conservancy, environmental protection, construction work, such as reservoir, navigation channel, lake dredging up, port dredging, channel excavation, harbour, dock accumulation are cleared up, and enclose extra large fill, beach filling, earthwork carrying and industrial residue are cleared etc.
