Abstract

The utility model relates to an all-directional automatic-jet washing apparatus, which is suitable for washing the inner walls of large or middle size containers, such as water-towers (boxes or pools), fermentation tanks, spherical tanks, oil tanks, etc. The utility model is composed of a standpipe, a vertical flow dividing pipe, a three-way pipe, a transverse flow dividing pipe, a side three-way pipe, a jet flow pipe, a nozzle, etc. The transverse flow dividing pipe and the jet flow pipe are provided with a wing plate which enables the mechanism of the utility model to perform an omnidirectional rotary jet. The loss that the jet speed is reduced by using the counterforce of liquid flow of the prior art is avoided. The stepless speed regulation of the rotation speed can be achieved by adjusting the obliquity of the wing plate.

Description

All-directional automatic-spray washing device

The utility model is a kind of automatic jet douche apparatus, is applicable to the flushing of bulk container inwall, is specially adapted to the flushing of water tower (case, pond) inwall.

The employing mechanical transmission mechanism that present existing cleaning equipment has makes nozzle make rotary-jet, is unsuitable for being fixedly mounted in the water washer as water tower.Majority is that the reaction force driving nozzle when utilizing nozzle to penetrate liquid stream is made rotary-jet, the automatic device for cleaning tank of ZL92244941.4 universal type as China's patent disclosure, it by vertical shaft, elbow, transverse axis, nozzle block, main jet chew, auxiliary nozzle etc. forms, several main jets are chewed the reaction force driving of ejection liquid stream and self are rotated around transversal line, the reaction force that auxiliary nozzle in the transverse axis outer end sprays drives main jet again and chews group around the rotation of vertical shaft axis, becomes universal injection.But, thereby there is the reverse velocity of following to reduce effluxvelocity, shorten range, increased energy consumption because of reaction force is opposite with jet direction.And often rotary speed is too fast restive.The one nozzle aims at and drives main jet and chew around vertical shaft and rotate and establish, and causes most of liquid of this nozzle to flow the loss of no cleaning performance.

The ZL92242029.7 automatic stereo injection equipment of China's patent disclosure and for example, this mechanism is fixed on internal tank and is the suspention shape, high-pressure cleaning liquid is penetrated by nozzle through three-way body, horizontal entire body, T shape pipe by column pipe, jet flow produces reaction force and impels nozzle to rotate at a high speed around the bearing block center line, because the Plane of rotation at nozzle and T shape tube hub line place has a drift angle, the reaction force of jet flow decomposites the moment of couple parallel with the bearing block center line makes horizontal siphunculus, nozzle etc. around column pipe center line low speed rotation, and such two make nozzle form the three dimensions jet motion to rotation.But the influence that also has the reverse velocity of following of nozzle has reduced speed and range, the too fast restive problem of rotary speed.

Problem in view of above-mentioned prior art existence.The purpose of this utility model is to overcome influence and the rotary speed restive problem of the reaction of jet velocity of following to effluxvelocity and range.

Task of the present utility model is finished as follows.

In a pair of horizontal isocon with in two pairs of jet pipes, be fixed with the wing plate that becomes an angle of attack with the liquid flow path direction respectively, when pressurised fluid stream by vertical tube through in the three-way pipe branch under the effect of pressurised fluid stream kinetic energy, produce tangential force when flowing through wing plate in the horizontal isocon horizontal isocon related two ends jet pipe and nozzle rotated along horizontal plane around riser axis, same in two pairs of jet pipes pressurised fluid stream kinetic energy act on tangential component on the wing plate and make two pairs of jet pipes and nozzle do rotation perpendicular to horizontal plane around horizontal isocon axis, two have synthesized omnibearing injection to rotation, and the control of nozzle rotary speed is to reach stepless speed regulation by adjusting the inclination angle of wing plate to Plane of rotation.

Advantage of the present utility model is directly to utilize the kinetic energy of pressurised fluid stream, has avoided utilizing liquid stream reaction force to influence the defective of effluxvelocity and range, simultaneously owing to use adjustable wing plate can realize spraying the stepless speed regulation of rotary speed more simply and effectively.

Accompanying drawing 1 is the front view of the comprehensive automatic jet douche device of the utility model;

Accompanying drawing 2 is the A-A cutaway view of accompanying drawing 1;

Accompanying drawing 3 is the B-B cutaway view of accompanying drawing 1;

Implement to elaborate below in conjunction with 1 pair of the utility model of accompanying drawing:

Jet douche device vertical tube (1) is fixed on container inner roof wall central authorities, syringe integrated suspension space center in container, vertical tube (1) upper end is connected with the high-pressure hydraulic pump outlet conduit, the lower end is connected with perpendicular isocon (3) by straight joint (2), friction pair and sealing ring are housed between the perpendicular coupling sleeve (5) of the outer suit of perpendicular isocon, pipe and cover manages and overlaps the frictional force of relative rotary motion and prevent that press water from leaking reducing.Perpendicular isocon lower end is made blind hole and is offered tap hole at the pipe end periphery, purpose be to reduce current in the vertical tube pair joining with perpendicular coupling sleeve (5) in the vertical impulse force of three-way pipe (6), to alleviate the frictional resistance that perpendicular coupling sleeve (5) rotatablely moves, current divide the horizontal isocon (7) of the both ends horizontal turning arm of flowing through by middle three-way pipe (6), the wing plate (12) that pressure flow installs through the nearly exit of horizontal isocon, water flow dynamic energy acts on the wing plate.Wing plate (12) has the individual angle of attack to the vertical plane of water (flow) direction, thereby flow to the horizontal isocons in two ends (7) when wing plate (12) by vertical tube (1) when pressure flow, the active force that water flow dynamic energy acts on the wing plate produces tangential component, because wing plate is to be packed in the horizontal isocon therefore two tangential component to form the moment of couple the related side three-way pipe of the horizontal isocon in two (11) jet pipe (13) and nozzle (17) are rotated along horizontal plane around the vertical tube axial line.Pressure flow same as above flows to the injection turning arm that two ends are made up of jet pipe (13) and nozzle (17) by horizontal isocon (7) through side three-way pipe (11) branch, because two ends jet pipe (13) also is fixed with wing plate (16), the tangential force that produces under the effect of water flow dynamic energy active force impels jet pipe (13) and nozzle (17) to rotate along the vertical plane that is parallel to riser axis around the axis of horizontal isocon (7).The stepless speed regulation of rotary speed is by adjusting the middle wing plate of jet pipe (13) inclination angle of Plane of rotation to be realized, concrete measure is to be connected at jet pipe (13) and side three-way pipe (11) abutting end to adjust cover (14), make wing plate that corresponding inclination angle be arranged by the relative angle of adjusting jet pipe offside three-way pipe, make rotating speed reach the purpose of stepless speed regulation thereupon changing.

Because injection equipment makes two pairs of nozzles do comprehensive at the uniform velocity rotation and simultaneously continuously liquid stream ejection directive is cleaned face the dirt that adheres to is washed away totally, be used to wash the effect that inwalls such as container such as water tower (case, pond) garden bucket, garden jar, spherical tank or oil carrier cabin all can obtain satisfaction no matter jet is topped comprehensively.
