Description
Technical field
The invention provides a kind of boiler scale removing device.
Background technology
Vertical medium small boiler (0.1～0.8 ton) comprise in shell, inner bag, the inner bag the multilayer boiler tube (usually, every layer of boiler tube comprises seven boiler tubes), the two ends of every boiler tube respectively with shell and inner bag between chamber communicate, water is in boiler tube and the chamber, and boiler tube and chamber constitute the water route of vertical medium small boiler.
Does not wait at 2000 yuan～50,000 yuan the market price of vertical medium small boiler.Consider price factor, vertical medium small boiler is not generally installed water softening treatment plant, in addition, does not throw in boiler detergent in the use in water yet.For this reason, vertical medium small boiler was often wanted blowing out once in 1 year, asked the professional to carry out scale removal and handled, and after 2～3 years, boiler Chang Yinwei fouling is seriously scrapped (wherein, the fouling situation of orlop boiler tube is the most serious), and service life is shorter.In addition, according to " national boiler water processing information network " investigation, the accident that causes because of poor water quality accounts for 24% of boiler breakdowns.
Understand the domestic present relevant apparatus that to remove incrustation scale in the generator tube that still do not have according to the applicant.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of incrustation scale and descale effect boiler scale removing device preferably of removing in the generator tube.
For solving the problems of the technologies described above, the structure of boiler scale removing device provided by the invention is: in the shell of boiler and the chamber between the inner bag driving shaft bearing is arranged, drive sprocket, at least one chain, at least one driven axle bearing, at least one driven axle, at least one is by movable sprocket, the driving shaft bearing, the driven axle bearing be installed in the chamber and respectively with inner bag in some boiler tube coaxial lines of layer, the incrustation scale that rotates in corresponding boiler tube all is housed in each boiler tube of some boiler tubes removes part, Connection Block be arranged on the outer shell outer wall of boiler corresponding to driving shaft bearing place and with driving shaft bearing coaxial line, driving shaft pass boiler jacket carry on a shoulder pole rotationally be placed on Connection Block and the driving shaft bearing and its inner and corresponding boiler tube in incrustation scale remove part and join, driving shaft cooperates with the Connection Block liquid sealing, drive sprocket is arranged on driving shaft and is on interior that section axis body of chamber, driven axle is fitted on the driven axle bearing, be arranged on the driven axle by movable sprocket, incrustation scale in the inner of driven axle and the corresponding boiler tube is removed part and is joined chain and drive sprocket, articulated cooperation by movable sprocket.
For can concise description for the purpose of the problem, below this boiler scale removing device be all abbreviated as this scavenge unit.
After adopting such structure, rotate driving shaft, the interior incrustation scale removing part rotation of corresponding boiler tube that makes drive sprocket and join with driving shaft, in addition, drive sprocket drives by chain and is rotated by movable sprocket, removed the part rotation by the incrustation scale that movable sprocket drives again in the corresponding boiler tube that driven axle reaches and driven axle joins, like this, remove the rotation of part by incrustation scale, can effectively dispose the incrustation scale on the corresponding boiler tube inwall, the incrustation scale of removing flows away along with flowing of water in the boiler water route, and incrustation scale can't be deposited in boiler tube for a long time, thereby has eliminated the negative effect that incrustation scale uses boiler.
Above-mentioned scale removal is handled, and can need not carry out at any time or regularly under the situation of blowing out, so that descale effect is better, and boiler life is prolonged.
Therefore, incrustation scale and the descale effect that adopts this scavenge unit can remove in the generator tube is better.
In addition, that this scavenge unit also has is simple and reasonable, fitting operation advantage easily.
Described incrustation scale is removed part by dwang, be arranged on the U-shaped hangers of dwang one end and sensing Connection Block, the wing plate and the some support ears that are arranged on the dwang constitute, wing plate and dwang are isometric, per two support ears are in the circumferential same cross section of dwang, be mutually 120 degree angles between two support ears in the circumferential same cross section of wing plate and dwang, wing plate, support ear and corresponding boiler tube matched in clearance, driving shaft, also there is the U-shaped hangers the inner of driven axle, and driving shaft is by the U-shaped hangers, driven axle articulates with the U-shaped hangers that corresponding incrustation scale is removed part respectively by the U-shaped hangers.
Like this, driving shaft, driven axle and corresponding incrustation scale are removed part and are movably connecting mode, dwang, the wing plate on the dwang and some support ears that incrustation scale is removed in the part make incrustation scale remove the defective that part can overcome boiler manufactured size error and burning distortion, so that can obtain the sufficient free degree.
Described Connection Block comprises the second flange tube that is installed on the outer shell outer wall and joins with the first flange tube of driving shaft bearing coaxial line, by the securing member and the first flange tube, in the first flange tube airtight and watertight padding that cooperates with the driving shaft liquid sealing is housed, be equipped with all with the axle sleeve of driving shaft socket in the second flange tube and lay respectively at two bearings at axle sleeve two ends, the outer end of the second flange tube is provided with driving shaft socket and the cover plate that plays the role of positioning, the inner has with the driving shaft socket and stretch in the first flange tube and the contacted exntension tubs of airtight and watertight padding.
An installing plate is arranged in the described chamber, and driving shaft bearing, driven axle bearing are arranged on the installing plate; Handle is equipped with in the outer end of driving shaft; Driving shaft bearing, drive sprocket, chain, driven axle bearing, driven axle, be stainless steel material by the material of movable sprocket, driving shaft.
Like this, after the above-mentioned parts in the chamber is immersed in the water, can avoid being corroded, guarantee to be equal to their service life the furnace life of boiler; The rotation of driving shaft is convenient in the setting of handle, driving shaft again the drive sprocket by articulating cooperation, chain, driven driven axle by movable sprocket and rotate, make incrustation scale remove part and in corresponding boiler tube, rotating, finish scale removal and handle.
