Description
Technical field
The present invention relates to the water intake end support component of inserted component in heat exchanger tube augmentation of heat transfer in the equipment such as a kind of shell-and-tube heat exchanger, heat exchanger and antiscaling, descaling.
Technical background
Development along with World Economics, energy shortage becomes world's problem of being badly in need of solution, energy-saving and emission-reduction become a key technology that solves energy problem, the shell-and-tube heat exchanger that is widely used in the industries such as oil, chemical industry, electric power, metallurgy, pharmacy and machinery, the quality of its heat exchange efficiency is directly determining economic benefit and environmental benefit.Yet the situation of ubiquity fouling on heat exchanger tube tube wall, not only causes the increase of flow resistance, and has reduced heat exchange efficiency, and the energy has been caused to great waste, the dirt in heat exchanger tube also easily causes underdeposit corrosion, has a strong impact on the safety of equipment.
For the problems referred to above, traditional method is to shut down methods such as adopting mechanical cleaning, Chemical cleaning it is cleaned, and the waste of the manpower and materials that not only cause, also causes the pollution of environment.Owing to shutting down, equipment is cleaned, also can delay production, cause huge economic loss.Can be in non-stop-machine situation for address the above problem that designer researching and developing always, online strengthening conducts heat and the method and apparatus of antiscale scale inhibition.China Patent No. is ZL200520127121.9, discloses the patent No. that denomination of invention is " rotator type cleaning and heat-transfer enhancing device ", and this device is to consist of suspension member, rotor, flexible shaft and stay pipe, and two suspension members are separately fixed at the two ends of heat exchanger tube; The outer surface of rotor has scroll, has centre bore on rotor, and flexible shaft is fixed on the suspension member at two ends through the centre bore of rotor.This device has the function of on-line automatic antiscale, scale removal and augmentation of heat transfer.Wherein suspension member is a kind of diversion type self-tightening hanging part, and China Patent No. is 201010184095.9, and it mainly comprises hollow shaft, connecting rod.Brace table and external part, it can well guarantee the centering of flexible shaft, larger but suspension member is arranged on the loss of the heat exchanger tube resistance that heat exchange tube inlet causes, and needs to install at the scene fixing in actual installation, installs consuming time more.For solving the large problem of suspension member comparison of resistance, Chinese patent 201210067268.8, disclose a kind of low flow-resistance quick-mounting hanger, this suspension member has solved the large problem of entrance comparison of resistance, but it is in actual project installation, this suspension member can only be installed at the scene, can not fit together in processing factory and plug-in part, increase on-the-spot installation work-hour, during due to installation, need to shut down and carry out, the time of shutting down is very limited, and on-the-spot mounting suspension member likely causes engineering extension to complete; And suspension member need to be spacing on central shaft suspension member with locating part fixedly time, because locating part is metal with central shaft, easily cause between locating part and central shaft and occur corroding, cause unnecessary loss.
Summary of the invention
The problem wasting time and energy for solving on-the-spot mounting suspension member, and fixing etching problem between the locating part of suspension member and central shaft, the present invention has designed a kind of suspension member that can be used for managing interior inserted component Fast Installation, this suspension member can be when factory-assembled and heat exchanger tube plug-in part fit together.During the interior inserted component of on-the-spot installation heat exchanger tube, suspension member can be combined into a complete work suspension member at mouth of pipe suspension member by left and right two parts with interior inserted component by heat exchanger tube, has saved the field erected time.The screw clamping device at suspension member top can make suspension member be fixed on central shaft, has prevented the corrosion between locating part and central shaft.
The present invention proposes a kind of self-locking suspension member of assembling, mainly by the beam texture on left support plate, right support plate, left support plate, stop-return slot and the threaded sleeve on right support plate, formed.On left support plate, there is left side sleeve pipe, on right support plate, there are the large sleeve pipe in right side and right side small casing, right side small casing matches with left side sleeve pipe, the coaxial device rotation that left support plate matches with left side sleeve pipe around right side small casing with right support plate, after right side small casing has coordinated with left side sleeve pipe, on the left of being longer than, on the part circumference of sleeve pipe, there is disappearance, small casing top, right side has external screw thread to match with threaded sleeve, and the stop-return slot in the beam texture in the gripper shoe of left side and right side gripper shoe has formed the self-locking device of suspension member.
