Description
Technical field
The present invention is that device is sent in the suction that a kind of environment-friendly type sludge pipeline is carried, and 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, the riverbed is improved.This not only reduces storage capacity, and 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 pipeline that is similar to the soft sticking material of mud character and carry.As seen, the 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 stream when moulding state, be difficult to realize feeding free from environmental pollution.By retrieving domestic and international patent documentation and relevant database, from the data that searches out as seen, a lot of experts and scholars' research has been made positive contribution in this technical field.Some useful theory and application studies have also been done.The early-stage Study of this seminar realizes the method and apparatus that soft sticking material remote pipe is carried.Chinese patent is arranged: 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), mud equipment (00247696.7) is failed in the environment-friendly type desilting, pipe-line transportation equipment for viscoplasticity materials (200720156216.2) has solved many difficult problems that soft sticking material remote pipe is carried effectively ".But, never capture this key technology of pollution-free feeding.
Economizing Natural Science Fund In The Light " the visco-plasticity mud tubes is carried new method and research on mechanism " (M503164), " bury---visco-plasticity material pipe post stream conveying characteristic research " (Y505041), Hangzhou emphasis innovation fund " mud equipment is failed in the environment-friendly type desilting " (20051321B13), under the subsidy of Department of Education of Shanxi Province's emphasis scientific research fund " the Binghambody pipeline is carried the research of new method and the defeated mud equipment of environment-friendly type desilting " (20010430).On the basis of the early-stage Study of seminar, invented a kind of sludge pipeline suction and sent device.
Summary of the invention
The object of the invention is to solve the suction that the environment-friendly type sludge pipeline carries and send a difficult problem, comprise shorten inhale apart from, prevent air intake, inhale and send conversion and improve and inhale the device that send 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 the suction nozzle, one end is connected with feeding pipe through joint, and the other end is connected with a few working cylinder commutations; Joint is interior, suction inlet is interior and the periphery working cylinder mouth is respectively equipped with the skin covering of the surface nozzle for liquid; The 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 the working cylinder, and a working cylinder is in pusher, all the other working cylinder suctions, the 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, send in suction and to meet obstructions in the process when larger, 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 to inhale and send efficient.Skin covering of the surface liquid adopts different prescriptions 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. owing to being connected with joint by J type reversal valve between several working cylinders and the feeding pipe, at the front end of working cylinder mouth side suction inlet is set, shortened the distance of suction inlet to the working cylinder mouth, with the suction journey of material, Effective Raise suction send efficient.
Because in suction inlet and the periphery of working cylinder mouth be respectively equipped with skin covering of the surface pendular ring type jet pipe and nozzle.Send in the process in suction, water content occurs 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 the lubricated and dewatering and coagulating of drag reduction, so that be lined with one deck suspension film between tube wall and the earth, the wall friction power of material is reduced, overcome the viscosity of material, ensured that material enters working cylinder smoothly, and reduced the resistance that material enters working cylinder.Improve to inhale and send efficient.Solved this crucial difficult problem of pollution-free feeding.
3. be placed in the material mouth owing to charging aperture is provided with J type valve, be provided with wear-resistant gasket with the working cylinder connection place, ensured the reliable conversion of material and continuously conveying.
4. because suction inlet is bell mouth shape, inhale and to send that the soil body is added an amount of skin covering of the surface liquid by compacted in the process, reduced to greatest extent the suction of air.Being filled rate for raising plays an important role.
5. because the pipeline of whole process using sealing is carried, solve the secondary pollution problem in the carrying.
The present invention is applicable to plastic state and flow regime, and namely natural moisture content send greater than the suction of the soil body of plastic limit.Not being only applicable to municipal sludge clears, and extremely widely purposes arranged in oil, chemical industry, mining, water conservancy, environmental protection, construction work, such as reservoir, navigation channel, lake dredging up, port dredging, channel excavation, extra large fill is enclosed in harbour, the cleaning of dock accumulation, beach filling, cubic metre of earth carrying and industrial residue are cleared etc.
