Description

Superlow frequency vibrating pipeline method for cleaning and superlow frequency vibrating pipeline cleaning dredging machine

Technical field

The invention belongs to hydraulic pressure and Pneumatic Transmission technology, relate to a kind of method of superlow frequency vibrating pipeline cleaning, and realize the employed superlow frequency vibrating pipeline cleaning of this method dredging machine.

Background technology

The maximum characteristics of modern urban construction are that building is more and more, and make the building resident that the most worried thing is the obstruction of sewer pipe.Pipeline cleaning machinery in the market all is to adopt machine driving to drive flexible axle (being helical spring again), and the flexible axle top twines the obstruction object that stirs in the pipeline by one group of blade is arranged by the blade rotation, it is wrapped up in out again.Here there are many problems, at first, in use, when flexible axle is put pipeline into, because flexible axle is that steel wire is pressed into screw type, have elasticity and certain rigidity, add that sewer pipe has bending, and flush toilet there is syphon structure, so turnover has certain difficulty, even can not free in and out sometimes, pressurization just can enter by machine. at allThe second, owing to can not free in and out, pressurization enters the siphonic system that usually can damage toilet by machine, if the constructor does not note also can damaging pipeline and decorative object sometimes.The 3rd, on principle, when contacting with obstruction owing to the flexible axle that rotates, obstruction is compared with the external force of the flexible axle that arrives in pipeline, liquid in the pipeline is given the pressure hour of its pressure ratio flexible axle, obstruction will be given in, to such an extent as to more allow darker, but can not be pushed into trunk line the time, this has just become very big problem, what pipeline occurred is false logical phenomenon, promptly is exactly logical at that time in real life, blocks up example in second day again.This phenomenon is considerable.

Because the mechanical pipe descaling machine can not solve the mediation problem of line clogging at all, the someone attempts to improve pipeline again, allow the special sewer of every household oneself, Here it is at present has been covered with various pipelines on the exterior wall of every building building on the building of sub-district, this changing its course not only needs the increase funds, and it is attractive in appearance to influence the sub-district, cause the contradiction of owner and infrastructure management company in the high class residential zone that has, though this difficulty for the moment that changed, the time has been grown, still want fouling in the pipeline, still unsatisfactory when the time comes.Moreover for high residential building will be at all can not external pipe.

Summary of the invention

In order thoroughly to solve above-mentioned building line clogging problem, overcome the deficiency of prior art mediation machinery, the present invention will provide a kind of superlow frequency vibrating pipeline method for cleaning of brand new ideas, and the pipe-dredging machinery of realizing the brand new of this method.

The technical scheme of finishing the foregoing invention task is:

Superlow frequency vibrating pipeline cleaning dredging method may further comprise the steps,

To treat that dredging pipeline is connected as tightness with pneumatic compression devices, and make it constitute a holonomic system;

Pneumatic compression devices is to treating that dredging pipeline applies negative pressure;

Reach after certain negative pressure numerical value, be transformed into and treat dredging pipeline output malleation;

So alternately apply negative pressure and malleation, the vibration frequency range of work is the 10-0.01 hertz, up to pipe-dredging.

Method of the present invention is unexistent in the conventional art.For example: in the conventional tool, by " toilet pulls out son " that the sucked type leather cup that is installed in the rod lower end constitutes, to pressing repeatedly, pull out, can apply malleation and negative pressure during use to pipeline at the sewer mouth.But this method and the present invention have the difference of essence: just can not produce effective negative pressure when at first this instrument produces effective malleation, just can not produce effective malleation when producing effective negative pressure, the two can only the tool one; Secondly, be quite low because it makes its vacuum that produces of draining around the cot by the air in the extruding leather cup, to compare with negative pressure of the present invention be very little to the negative pressure of generation when manually stirring.It can only stop up limited effect to the superficial part of pipeline opening annex, do not reach the effect of cleaning the deep pipeline at all.

The prioritization scheme of pipeline cleaning method of the present invention is: be set to vacuum 0.02Mpa by negative pressure; By malleation is 0.4Mpa; Vibration frequency is by the decision of the quality of cutoff pressure and vacuum generator, generally can be preferably at 1-0.1Hz.

The employed equipment of above method can be devices such as air pressure conversion equipment of the prior art or air pump, but in order to reach ideal effect, the application recommends to adopt following equipment:

Superlow frequency vibrating pipeline cleaning dredging machine is provided with air pump, and this air pump to choke valve, connects vacuum generator through an outlet order of first reversal valve again, and this vacuum generator is connected through an inlet of the filtering core device and second reversal valve; Another outlet of first reversal valve directly connects another inlet of second reversal valve; The efferent duct end of this second reversal valve is provided with pressure bladder outward.

The prioritization scheme of the said equipment is: be connected to the tentacle of nozzle type at the efferent duct end, the structure of this tentacle is: the rigidity short tube that is connected with efferent duct, and short tube oral area periphery is provided with hangnail, and described pressure bladder is located at the periphery of tentacle.

Described pressure bladder is connected in order to carry out tightness with pipeline to be dredged.During use efferent duct end or tentacle are placed in the pipeline for the treatment of dredging pipeline, make this equipment and pipeline to be dredged connect into a complete system, dredge successfully, can take out this equipment easily afterwards to air bag deflation to airbag aeration; Sometimes in the time of will getting obstruction, bleed off the gas in the air bag, take out tentacle obstruction is taken out.This equipment alternately applies malleation and negative pressure to pipeline with the power source of air pump as work, makes pipe-dredging.Its concrete steps are: this equipment is connected closely with pipeline to be dredged after, open air pump, when air pump reaches certain pressure, first reversal valve is placed first operating position, the high velocity air of air pump flows into vacuum generator through first reversal valve, one-way throttle valve, made by vacuum generator and to treat to produce in the dredging pipeline vacuum, the liquid in the pipeline flows to vacuum generator through the puff prot of tentacle and second reversal valve and filtering core device; Reach after certain negative pressure numerical value the operating position of conversion first reversal valve and second reversal valve: the air-flow of air pump is directly treated dredging pipeline output malleation through the efferent duct of first reversal valve, second reversal valve.So alternately apply negative pressure and malleation, up to pipe-dredging.

Described first reversal valve can adopt the hand rotary valve; Second reversal valve can adopt hand valve.

Described pressure bladder can adopt and be enclosed within outside the efferent duct or the outer spherical inflatable airbag of the tentacle of metal air jet pipe, and is easy to use.

The air pump that is disposed adopts general small-sized pump just can reach job requirement.

Vacuum generator vacuum requires to reach 0.08Mpa.

Prioritization scheme of the present invention is, also is provided with air gauge on gas circuit, and in order to controlled pressure numerical value, controlled pressure numerical value is so that the operation when using: the present invention recommends following numerical value: be set to vacuum 0.02Mpa by negative pressure during use; By malleation is 0.4Mpa.Simultaneously, by the control to two reversal valve actions, the vibration frequency range that makes work is the 10-0.01 hertz.Vibration frequency is by the decision of the quality of cutoff pressure and vacuum generator, generally is selected in 1-0.1Hz and gets final product.

Here the place that will note is noted that by negative pressure and setting by malleation to be provided with too highly for the old pipeline that has, otherwise can cause old pipeline violence.And the situation that does not have the pipeline violence also can flow to because of ducted liquid and damages machine in the vacuum.

The present invention has changed the principle of using in the background technology fully on theory, adopted air-driven principle.Because the Pneumatic Transmission of using, advantage at first is not contact with obstruction with flexible axle, according to hydromechanical principle, utilize fluid and obstruction (pipeline and this equipment are connected into same system) in the pipeline, exerting pressure to system just to make obstruction move in pipeline, and when awarding normal pressure, obstruction moves downward, when we executed negative pressure, obstruction will move upward.Change pressure repeatedly, liquid vibrates repeatedly in pipeline and reaches the effect of clearing up pipeline, for the obstruction of bigger difficult motion, it is guided to tentacle of the present invention, it can be taken out.
