Description

Pipeline cleaner
The present invention relates to feedwater and draining field, more particularly relate to pipeline cleaner.
This device is best suited for removes the industrial pipeline of carrying high-concentration turbid liquor.
In addition, the present invention also can be used for removing various containers: the suction chamber of pumping plant, the storage cistern of cooling tower, sedimentation basin etc.
The device of known removing pipeline (SU, A, 173678) disposes with compressed gas source inlet communicating chamber, is used for the plenum chamber and the piston that communicate with pipeline along its longitudinal axis in its pump case.The piston that is configured in the plenum chamber is made up of the part of two different-diameters of fixedlying connected with piston rod, and the cylinder configuration of minor diameter is in the hole of the ball valve that is arranged in filter area, and strainer is configured in the back of plenum chamber along the compressed air stream flow direction.Spring is housed on the piston rod, and an end bearing of spring is on large diameter piston; The other end then is bearing on the ball valve seat.
Under the effect of plenum chamber air pressure, piston moves on compressed air stream air feed flow path direction.In this case, small bore piston is deviate from from ball valve orifice, has reduced the resistance of motion of liquid by ball valve orifice, promotes piston accelerated motion.Enlarged bore piston is opened the hole in the plenum chamber housing, in the medium around the compressed air in the plenum chamber pours " outburst ".Under spring and hydrostatic pressure effect, piston turns back to original position, and at this moment, valve ball lifts slightly, and liquid leads to below the piston through strainer, and repeats this process.
This device is mainly used in handles the zone of well near the shaft bottom, simultaneously, forces along being eliminated surperficially when mobile when device, also can be used for removing the setting-out pipeline of carrying the low concentration suspension.Thereby pressure and the gas blow-through parameter of compressed air in plenum chamber determined and adjusting by spring force and liquid water static pressure value.
This pipeline cleaner can not be used for the pipeline of following purposes owing to following reason:
-be applied under the bigger situation of dynamic load on the moving parts, limit the life-span of this known devices owing to there is spring to exist, and changed its running parameter;
-owing to there is not the hydrostatic pressure of surplus to exist in the pipeline, do not allow to utilize known devices to remove daily life sewer and industrial sewer;
-owing to have strainer and ball valve to exist, do not allow to utilize known devices to remove the pipeline that those carry high-concentration turbid liquor;
-because this device does not have autonomous moving, not allowing to be used to remove those can not be with tow by being eliminated the pipeline of part.
Task of the present invention is to create a kind of pipeline cleaner, its structure can guarantee that parameter, the chamber of automatic adjustments of gas outburst do not stop up, surface autonomous running parameter and fluid pressure mobile, device are irrelevant along being eliminated, and this device can be worked under the very big condition of compressed air pressure excursion.
The solution of being offered the challenge is: in the housing of pipeline cleaner, dispose with compressed gas source inlet communicating chamber, be used for the plenum chamber and the piston that communicate with pipeline along its longitudinal axis; According to the present invention, in housing, be provided with two auxiliary chamber that separate with the air exhaust system of piston, wherein first chamber communicates with ambient medium, the gas transmission mechanism of second auxiliary chamber on the plenum chamber valve communicates with plenum chamber, communicate with inlet through the central passage on the piston, the piston and the second ancillary chamber opposing end faces are long-pending greater than long-pending with the inlet opposing end faces, but the end area less than the piston annular lip relative with second auxiliary chamber is processed with several passages in the compressed air outlet zone in plenum chamber one side.Wherein the longitudinal axis of each passage and compressed air stream reaction force vector coincide.
For guaranteeing that compressed air in time charges into plenum chamber to given pressure, the aerophore body plan has vertical passage that communicates with second auxiliary chamber and several radial holes that communicate with vertical passage and plenum chamber.
More rational is that the exhaust system of piston is several passages along the piston end surface arranged around relative with inlet, these passages are linked up inlet and the lip-deep cannelure of outside piston, when the exhaust of second auxiliary chamber, cannelure communicates with ambient medium through the through hole in the housing inlet zone again.
This structural concept of piston exhausting system has reduced the influence of piston damping in the inlet, and has improved its snap action.
Entering the air-damped influence of inlet in order to reduce, in order to guarantee to increase the time that piston turns back to original position, thereby also is in order to utilize the volume of plenum chamber more fully, just must the compressed air governor motion to be housed to inlet.
When pipeline cleaner is worked under the lower situation of compressed air pressure, adopt the compressed air governor motion to suit, this mechanism comprises a vertical passage that communicates with compressed gas source on the end face that is positioned at housing inlet zone at least, be securely fixed in bar on the piston end surface of inlet's one side with at least one, the longitudinal axis of bar and the axis of vertical passage coincide, when the exhaust of second auxiliary chamber, this vertical passage is stopped up by bar.
When pipeline cleaner is worked under the very big situation of compressed air pressure excursion, compressed air air feed governor motion more reasonable plan is to have a passage that is positioned at housing inlet zone at least, the one end communicates with compressed gas source, the other end-promptly when the exhaust of second auxiliary chamber by outer surface of piston a topped end-then communicate with inlet.
Second auxiliary chamber can be made the form of high-voltage tube, owing to can will have the housing parts of a large amount of through holes, comprise that the inlet and first auxiliary chamber and piston wherein move on to the back of the pipeline scope that is eliminated, thereby the present invention can be used to remove the pipeline of pumping high-concentration turbid liquor.
Must on the valve in the second auxiliary chamber zone, be shaped on annular lip, so that between second auxiliary chamber and plenum chamber, form auxiliary chamber.
When the high-voltage tube form was made by second auxiliary chamber, this structural concept of valve can increase the evacuation time of plenum chamber, improved compressed air energy and utilized situation.
Gas transmission mechanism forms with the passage of auxiliary chamber and several vertical passages of making in annular lip by linking up second auxiliary chamber, wherein each passage is equipped with one way valve, when compressed air charged into plenum chamber, these vertical passages were linked up auxiliary chamber and plenum chamber.
This structural concept of required air delivery device is in order to prevent that compressed air from leaking into second auxiliary chamber of making the high-voltage tube form from plenum chamber.
In order to reduce the influence of the compressed air damping in the auxiliary chamber, promptly be in order to improve the snap action of valve, just in order to increase the explosive force of gas, must install exhaust system to valve, this exhaust system is a passage and the cannelure on being configured in around the valve end face relative with second auxiliary chamber at least, this passage second auxiliary chamber, one side be choke-out and communicate with auxiliary chamber, this cannelure is positioned at the zone of housing second auxiliary chamber, when the plenum chamber exhaust, through the through hole of valve and the channel connection of valve, the safety valve in the passage by the housing second auxiliary chamber zone and every the passage communicates with ambient medium.
The pipeline cleaner that the present invention proposes is used to remove the pipeline or the container of any purposes, comprising the industrial pipeline that is used to carry high-concentration turbid liquor.In this case, this device can be made into two kinds of patterns: wherein a kind of pipeline of removing the suspension of pumping intermediate concentration that is mainly used in; Another kind mainly is to be used to remove the pipeline of pumping high-concentration turbid liquor.This device can (from 3 to 20 MPa) be worked under the very big situation of compressed air pressure excursion, can guarantee to regulate automatically the compressed-air actuated pressure in the plenum chamber.In addition, autonomous the moving of the device that is proposed can guarantee to remove the bigger pipeline of length.The shock wave that this removing plumbing installation produces in liquid by means of gas blow-through destroys the sedimentary deposit on the inner surface of pipeline, also can in pollutant, work, and the shock wave that gas blow-through produces can destroy the sedimentary deposit of any hardness, recovers carrying capacity of pipe to design objective.

Pipeline cleaner working method of the present invention is as follows:
If device is worked under the lower situation of compressed air pressure, and the liquid of being pumped contains the suspended material of low concentration, so, should adopt first structural concept of above-mentioned compressed air air inlet adjustment mechanism, promptly compressed air is seen Fig. 4 through joint 3() enter inlet 2 by vertical passage 23.
When device is worked under the bigger condition of compressed air pressure excursion, then adopt second structural concept of compressed air air inlet adjustment mechanism, in this case, compressed air is seen Fig. 5 from the compressed gas source (not shown) through joint 3() see Fig. 1 along passage 26 by axial hole 41() enter inlet 2.
Under compressed air is applied to pressure effect on the end face 9, piston 5 is pressed to the valve seat 42 of housing 1, at this moment, compressed air is seen Fig. 1 from the 2(of inlet) flow into second auxiliary chamber 7 along the central passage 12 of piston 5, enter plenum chamber 4 from the radial hole 19 of chamber 7 on the piston rod 16 of the vertical passage 18 of valve 14 and valve 14.
After the compressed air of the plenum chamber 4 and second auxiliary chamber 7 reaches required pressure, the pressure (Fig. 2) that acts on piston 5 end faces 8 acts on pressure on piston 5 end faces 9 greater than compressed air, so piston 5(Fig. 8) 42 directions to inlet 2 that begin to lift off a seat move.In a single day piston 5 leaves the valve seat 42 of oneself, and compressed-air actuated pressure just expansion acts on the end face 10 of piston 5 annular lip 11.Obviously increase owing to the area difference between the surface 8 and 10 of piston 5 makes piston 5 translational speeds, in fact the through hole 43(that opens housing 1 sees Fig. 8 moment), discharge the gas pressure in second auxiliary chamber 7.
Air exhaust system in the piston 5 and compressed air fuel regulating system impel piston 5 movement velocitys to accelerate (quick acting).
Cooperatively interacting in the cannelure 21 of piston 5 and hole 22 in housing 1 inlet 2 zones reduces the pressure of inlet 2 down, because compressed air 20 flow to the medium on every side from chamber 2 along passage, thereby has eliminated the influence of piston 5 dampings in the inlet 2.
When the direction of inlet 2 was moved, the compressed air fuel regulating system had dwindled the overflow section that leads to inlet 2 from the compressed gas source (not shown) at piston 5, thereby had also reduced the influence of piston 5 dampings.
When adopting the compressed air fuel regulating system, stopped up by bar 24 by the first scheme vertical passage 23; By third party's case, passage 26 is topped by the body of piston 5.
Rely on the compressed-air actuated pressure differential in second auxiliary chamber 7 and the plenum chamber 4, valve 14 is shifted to second auxiliary chamber 7 fast, at this moment, compressed air is seen Fig. 9 through passage 44() the head 28(that enters housing 1 sees Fig. 8), and " outburst " drains in the medium on every side therefrom.
After pressure in second auxiliary chamber 7 reduced, under the compressed air pressure effect that enters through the overflow section that dwindles, piston 5 was shifted to second auxiliary chamber 7 lentamente.All vertical passage 23(see Fig. 4) firm opening of overflow section (by first scheme) or passage 26(see Fig. 5) firm the opening of overflow section (pressing alternative plan employing compressed air air feed governor motion), piston 5 is shifted to second 7(of auxiliary chamber and is seen Fig. 1) movement velocity obviously increase.In this course, piston 5 has covered in through hole 43 or 22.After this, the compressed-air actuated pressure in second auxiliary chamber 7 increases, and valve 14 begins to move as a result, withstands up to the valve tail till the valve seat 45 of housing 1 head 28, and device repeats work then.
Remove when pumping the pipeline of high-concentration turbid liquor when needs, adopt second auxiliary chamber 7 to see Fig. 6 for high-voltage tube 29() structural concept of form.In this case, compressed air is seen Fig. 7 along high-voltage tube 29 through the passage 32(of valve 14 heads 15) enter auxiliary chamber 31, one way valve in vertical passage 33 34 enters plenum chamber 4 then, and vertical passage 33 is positioned on the annular lip 30 of head 15 of valve 14.One way valve 34 be used to prevent air from plenum chamber 4 to auxiliary chamber's 31 seepages.
The time that valve 14 is shifted to plenum chamber 4 one sides is obviously shifted to the time of high-voltage tube 29 1 sides greater than valve 14, this be since at the face area of the head 15 of the valve 14 of plenum chamber 4 one sides greater than cause towards the face area of the valve head 15 of high-voltage tube 29.
At valve 14 when high-voltage tube 29 directions are moved, compressed air flows in the ambient medium from the through hole 39 of auxiliary chamber 31 through passage 35, through hole 38, cannelure 37 and housing 1, reduce the influence of the compressed air damping in the auxiliary chamber 31, and improved the snap action of valve 14.
Be installed in safety valve 40 in the through hole 39 and prevent that exhaust system silts up.
Adopt the further work process of the device of high-voltage tube 29 to be undertaken by following mode.
When " outburst ", seeing Fig. 8 each time by through hole 27() under the reaction force acts that produces of the air-spray of ejection, device moves along pipe surface to be removed.
Form bubble when " outburst ", in liquid, produce shock wave, destroy the sedimentary deposit on pipeline or the inner surface of container.
Because all through holes the 22,13, the 43rd, compressed air air feed side rather than in air ejection side respectively with inlet 2 and two auxiliary chamber 6,7 and ambient medium communication, thereby above-mentioned way has guaranteed that these chambers are not blocked.
" outburst " frequency can be controlled with the overflow section of the central passage 12 of selecting piston 5.
