Description
Technical field
The present invention relates to device that the heat exchanger in the flue is cleaned, refer to a kind of Tube Sheet of Heat Exchanger group outer wall mechanical ash removing device particularly.
Background technology
At present, the deashing device that is used for heating furnace air heat exchanger or similar field pipe heat exchanger such as hydrophily formula heat exchanger, heat exchange of heat pipe etc. roughly comprises following several kinds: acoustic wave ash ejector, gas-burning pulse ash-blowing device, steam sootblower, air duster, water jet soot blower, shot cleaner or the like.The technical difficulty of preceding two kinds of soot blowers is bigger, and it is different and different because of the type of heat exchanger form and dust stratification to blow grey conceptual design, is difficult for grasping, and is difficult to accomplish not stay the dead angle, and dedusting effect is limited.Steam sootblower, air duster, water jet soot blower difficult arrangement, the dead angle is many, installs huge.Simultaneously, the water jet soot blower makes dust stratification become sticking tide, deposition easily, causes the acid corrosion of exchanger tube wall to increase the weight of.And the steel ball rate of recovery of shot cleaner is low, and deashing has the dead angle, if run into sticking ash, steel ball is just clung the production clogging by ash, the dedusting effect extreme difference halfway easily.In addition, also have other some mechanical ash cleaners, but great majority need the heat exchanging road to carry out machine rebuilding when using, reduction again after deashing finishes exists occupation mode complicated, the shortcoming that the cycle is long and expense is high.
Summary of the invention
The object of the invention is exactly that the Tube Sheet of Heat Exchanger group outer wall that a kind of power consumption is little, cost is low, ash-removal effect is good mechanical ash removing device will be provided.
For realizing above-mentioned purpose; The Tube Sheet of Heat Exchanger group outer wall mechanical ash removing device that the present invention designed comprises the base that is provided with travelling wheel, is separately installed with main support rod and bridge motor on the said base; Said main support rod is provided with vertical guide; Be provided with slide block in the said vertical guide, said slide block links to each other with the outer ring of slewing bearing, and the inner ring of said slewing bearing links to each other with drive motors; The output of said drive motors links to each other with an end of rotating shaft, and the other end of said rotating shaft links to each other with wire brush; Simultaneously, the top of said main support rod is provided with fixed pulley, and the output of said bridge motor links to each other with an end of steel wire rope, and the other end of said steel wire rope is walked around fixed pulley and linked to each other with the outer ring of slewing bearing.
Further, the output of said drive motors links to each other with an end of rotating shaft through decelerator, shaft coupling.Said drive motors and decelerator can integrated designs, with simplified structure, and reduced volume.
Again further, an end of said rotating shaft is provided with supporting sleeve.Like this, can strengthen the strength and stiffness of the cantilever design of forming by rotating shaft and wire brush.
Again further, said travelling wheel is a universal caster wheel, is provided with four, is distributed on four angles of base.Like this, movable base flexibly, thus deashing device is all around moved easily.
Further, said rotating shaft is scalable adjustable type rotating shaft.Like this, can control the length of rotating shaft as required, thereby make wire brush be in best deashing position.
Operation principle of the present invention is such: based on base and travelling wheel, deashing device can move freely in being furnished with the flue of heat exchanger, comprises moving forward and backward and transverse moving left and right; Based on guide rail, slide block, bridge motor and steel wire rope, deashing device can be made the rectilinear motion on the vertical direction; Based on pivoting support bearing, deashing device can be done the rotation of certain angle at perpendicular.Through the reasonable cooperation of above three kinds of motion modes, the deashing scope can cover all outer surfaces of whole Tube Sheet of Heat Exchanger group.
The invention has the advantages that: design is directly contacted with Tube Sheet of Heat Exchanger group outer wall surface by the wire brush that rotating shaft drives, and utilizes the kinetic energy of rotatable wire brush to clear away the dust stratification on the Tube Sheet of Heat Exchanger group from the surface, for dry state and hygrometric state dust stratification good effect is arranged all.Select the suitable moving step length of deashing device, be easy to realize the heat exchanger outer wall surface thorough deashing, do not stay the dead angle.And the drive motors that is adopted only need overcome the frictional resistance of deashing device, so power is little, and energy consumption is extremely low.Simultaneously, this deashing device is independent of heat exchanger, and volume is little, can directly be placed in the residing flue of heat exchanger to use, convenient, the flexible and saving working time.In addition, through simple modification physical dimension, just can adapt to different size, different size and difform Tube Sheet of Heat Exchanger group, the scope of application is extensive.
