But the prior art that the above-mentioned patent document of take is representative, in actual use, still exists following defect: one, this damping device need to supplement nitrogen when vibration damping in nitrogen chamber, exists the shortcoming of complex process; Two, because three entrance valve chambers are different apart from the distance of damping device, cause the pressure imbalance of three entrance valve chambers, poor to the effectiveness in vibration suppression of pipeline, pipeline is still easily damaged.
Summary of the invention
The purpose of this utility model is to solve the above-mentioned problems in the prior art, provide a kind of for starching the vibration damping equipment of congee conveyance conduit, the utility model can effectively reduce the impact force to conveyance conduit while carrying slurry congee, the working life that can improve conveyance conduit.
For achieving the above object, the technical solution adopted in the utility model is as follows:
For starching a vibration damping equipment for congee conveyance conduit, it is characterized in that: comprise the vibration damping pipe of upper and lower closed at both ends, the lower end of described vibration damping pipe is provided with two symmetrical connecting tubes, two connecting tubes are all vertical with vibration damping pipe; The upper end of described vibration damping pipe is provided with for sealing the plug of vibration damping pipe, is provided with drain tap on plug; Described vibration damping pipe is fixedly connected with slurry congee conveyance conduit with flange by connecting tube.
On the inwall of described vibration damping pipe, be provided with pressure tester, on the outer wall of described vibration damping pipe, be provided with voice guard, described pressure tester is connected with voice guard.
On described plug and vibration damping pipe, be provided with flange, described plug is fixedly connected with vibration damping pipe with bolt by flange, and is provided with sealing layer between plug and vibration damping pipe.
The diameter of described vibration damping pipe is 1.5-50cm, and length is 50-100cm.
Employing the utility model has the advantage of:
One, in the utility model, conveyance conduit produces vibration and mainly contains following two kinds of reasons, the one, due to slurry congee, carrying the pump adopting is slurry congee pump, belong to positive displacement pump, can form a kind of pulse to conveyance conduit in the running, rotating speed more fast pulse is stronger, and the axial vibration that conveyance conduit is produced is also larger; The 2nd, there is gas bubbles in the slurry congee in conveyance conduit, flows and also can produce vibration to conveyance conduit in conveyance conduit; Therefore by the vibration damping pipe perpendicular to conveyance conduit, not only can effectively reduce the impulse oscillation that slurry congee pump produces, can also effectively reduce the vibration producing while starching the interior bubbly flow of congee, be conducive to the pressure of buffer system, better to the effectiveness in vibration suppression of conveyance conduit; And drain tap can be to the pressure release of vibration damping pipe, convenient operation person overhauls vibration damping pipe by plug; Compare for the prior art of representative with China Patent No. " 201020201478.8 ", the utility model is not only simple in structure, is convenient to install, and also has advantages of that long-term use do not rupture.
Two, in the utility model, on the inwall of described vibration damping pipe, be provided with pressure tester, on the outer wall of described vibration damping pipe, be provided with voice guard, described pressure tester is connected with voice guard, when pressure tester detects vibration damping overpressure and is greater than setting value, voice guard sends warning, and operator can pass through drain tap pressure release in time, can avoid the generation of security incident, this structure has significantly improved the safety in utilization of vibration damping equipment.
Three, in the utility model, on described plug and vibration damping pipe, be provided with flange, described plug is fixedly connected with vibration damping pipe with bolt by flange, and be provided with sealing layer between plug and vibration damping pipe, this structure not only guarantees the better tightness of vibration damping pipe, also helps operator and observes and process emergency situations by opening plug.
Four, in the utility model, due to when operation, to starch the vibration that congee pump produces very large, if the diameter of described vibration damping pipe is less than 1.5cm, length is less than 50cm, will cause vibration damping pipe to vibrate together with conveyance conduit, and conveyance conduit easily damages; And if the diameter of vibration damping pipe is greater than 50cm, length is greater than 100cm, and vibration damping pipe exists again the shortcoming of cost height and Heavy Weight; Therefore the diameter of described vibration damping pipe is set to 1.5-50cm, and length is set to 50-100cm, under maintenance prerequisite easy for installation, and the working life that can improve conveyance conduit.
