Abstract
A method and a tool for increasing the width in the clear of a chimney, for instance for the cleaning of chimneys, combustion chambers, boilers and the like, which on internal surfaces are covered with coatings, e. g. tarry deposits, by means of strokes from chains. The tool is provided with a holder (4) located at the end of a rotatable shaft (6), to which holder are attached chains parts (5), e.g. consisting of simple, elongated chain links, so embodied that the chains (5) are located in several levels at right angles to the axis of rotation and are firmly fixed. In this manner several impacts at one single point are obtained, the chains being kept in their tracks by the neighbouring chains, thereby obtaining a much more effective and rapid chimney cleaning, just asto a large extent soot flakes are pulverized, whereupon they drop to the bottom in the chimney. The method and the tool may also be used for increasing the width in the clear in comparison with the original width in the clear, whereupon a chimney lining may be inserted.
Description
The invention relates to ε method for increasing the width in | the clear of a chimney by means of a rotary tool having . s radially yieldable means, and an apparatus for carrying out the method for increasing the width in the clear of a chimney * by means of a rotary tool comprising a holder mounted at the free end of a rotatable shaft and having chains, consisting for example of simple, elongated, ring-shaped chain links, which are fixedly mounted on several levels at right angles to the rotatable shaft.
In this specification, the phrase width in the clear means the structural internal width of a chimney, or where there is a deposit of soot on the internal surface, the effective width allowing for the soot. Consequently, increasing the width in the clear may mean removing soot, or removing a chimney lining or structural materials generally, depending on the context.
It may be desirable to increase the width in the clear ox an existing chimney if, for stoking^tschnical reasonse internal insulation with lining tubes of a diameter larger than the existing width in the clear is required, for instance when switching to another type of fuel or to a new stoking system.
Thus, it is known that the older chimneys have such a width in the clear that is has been possible, without any problems to insert a lining tube in the chimney when switching to e.g. oil firing. In a possible subsequent change-over to gas firing where the width in the clear of the chimney should be still smaller, the width In the clear of the lining previously inserted ie however too small to permit inserting the new lining and, hence, it is necessary to mill out the existing lining tube.
After a chimney fire, the chimney must be rebuilt, which normally makes it necessary to pull down the chimney and rebuild it, with consequential drawbacks and substantial costs owing to roof covering, work to be done by carpenters and painters as well as waste of resources, even if the external construction of the chimney is all right. This would, be overcome if means were available for increasing the width in the clear of the chimney in such a manner that a lining tube could be inserted to restore the damaged interior face of the J 5 chimney or replace a lining tube previously mounted, FR—A—707,546 discloses a method for increasing the width in the clear of a chimney by m<£ans of rotary bodies, in which method the inside of the chimney is processed by strokes of high intensity from several bodies disposed on different levels. Said bodies are rigid plates each of which is pivotally mounted on a shaft which is provided on a holder in such a manner that the bodies can execute but a limited pivotal movement. This tool is capable of increasing the width in the clear of an existing chimney, provided it consists of suitable soft material, but because of the restricted pivotment of the bodies, this tool can only be used in chimneys where the width in the clear is merely reduced to an insignificant extent, for instance by deposits of shining soot. Therefore, this tool cannot be used for increasing the width in the clear of an existing chimney to such an extent that it will be possible to insert a lining in the widened chimney.
From SE—Λ—177,343 and 177—783, it is known to process the internal surfaces of a chimney with strokes from single chains to loosen soot from the chimney wall. In the tools disclosed therein, chain parts are slidably mounted in an axial direction on straps, which means that if a chain hits a coating or a firm object it will be struck off the course, whereby the intensity of the impact becomes rather low. 4 30 Further, the chains are disposed on separate levels and, * hence, cannot support each other if they hit an obstacle of d the type mentioned above.
Xt is therefore an object of the invention to provide £ method that can b® used for increasing the width in the clear of a chimney in relation to the existing width. The method of the invention should allow not only to remove assisting soot deposits in the chimney but also to remove materials from the interior wall surface of the chimney to such an extent that a lining tub© can be inserted in the chimney.
According to the invention, this object is achieved by a method of the above-mentioned type, which is characterized in that use is made of a rotary tool having chains disposed on several immediately adjoining levels, that the rotary tool is lowered from the top of the chimney to the bottom thereof, that the tool guided by guide means is moved upwards through the chimney while increasing the width in the clear thereof to a greater value than that of the original width in the clear, that the material pulverized during the reaming operation is withdrawn at the bottom of the chimney, for instance by a vacuum cleaner, that a lining of an internal diameter corresponding to the original width in the clear is inserted in the widened width in the clear, the external diameter of the lining being slightly less than said greater value of the width in the clear of the chimney, and that a remaining void between the lining and the inner wall of the chimney is filled with a material, preferably a mass capable of producing an intimate bond between the inner wall of the chimney and the outer wall of the lining.
For starting the reaming of the chimney or the object concerned from the bottom, the fool is pulled up through the chimney. Xf, on the other hand, the fool should be inserted te from the top of the chimney, if had been necessary fo subject the flexible shaft fo a pressure in the longitudinal direction thereof, whereby the shaft would easily be deflected with detrimental consequences. Also, the reming operation according to the invention is conveniently started in that the tool can bs guided in the original width in the clear of the chimnsy. It is also achieved that the material removed hy the reaming operation can drop freely through the widened ^idth in the clear of the chimney to the bottom thereof, whers&s when When, after the reaming operation, the tool h&rs b - 6 inner wall of the chimney is filled with a suitable material, preferably a mass capable of providing an intimate bond between the inner wall of the chimney and the lining.
Reaming of a chimney with the subsequent insertion of a lining ® tube in the chimney can be carried out by the method and the apparatus according to the invention at a relatively low cost and without any additional expenses for roof covering, work required by carpenters or painters. The cost should be compared with the costs for rebuilding the chimney.
The invention also relates to an apparatus for carrying out the method for increasing the width in the clear of a chimney by means of a rotary tool comprising a holder mounted at the free end of a rotatable shaft and having chains, consisting e.g. of simple, elongated, ring-shaped chain links, which are fixedly mounted on several levels at right angles to the rotatable shaft, said apparatus being characterized in that the chains are disposed on levels immediately adjoining each other, that the rotatable shaft is rotatably mounted immediately above said holder in a guiding unit having outer dimensions at right angles to the rotatable shaft which are but slightly less than the original width in the clear of the chimney, and that the tool comprises means for lowering and lifting the guiding unit, the shaft, the holder and the chains in the chimney.
This tool is very simple and makes it possible in an appropriate manner to carry out the method of the invention, in that the apparatus according to the invention permits processing the inner side of a chimney or a chimney lining at a high intensity and by means of several chains as stated above. ΐ According to the features of claim 4, there is achieved an apparatus t^hich is simple and cheap to manufacture and which can be descended through th& opening of a chimney fo b© milled before the insertion of a lining.
By using chains with an odd number of links, an extremely simple method of manufacturing the tool is achieved, and it becomes easy to ensure the balance of the holder which becomes self-centering to a great extent.
According to the features of claim 5, the u^e of chains on several levels, preferably eight, at right angles to the rotatable shaft ensures adequate processing of a suitably large sone in a chimney as the chains simultaneously support each other in & suitable manner. Also, there is achieved an apparatus which is not too heavy and which is easy to handle, and there is provided a better possibility of reaming or cleaning chimneys with openings that do not extend linearly, which is often the case especially in older houses, where the chimney pot is located on the roof ridge and the vertical part of the chimney is offset in relation thereto.
Further, according to the features of claim 6, it is appropriate to use chains consisting of a hard and heavy material, for instance hardened steel, the uttermost chain links optionally containing diamond dust, and fo form the chain links preferably with a thickness of 5~6 mm, so as to obtain elements that are suitably hard and have a sufficiently large mass fo process the inner side of the chimney with the force of impact required.
Moreover, according to the features of claim 7, if is appropriate to have the means for lowering and lifting the guiding unit, the shaft, the holder and the chains comprise a rack which can be mounted on the top of thi? chimney and which h&e a pulley for guiding the flexible shaft, so ass fo achieve a simple way of operating the rotary tool.
The invention will be described in more details below with reference to the drawings, wherein Fig. 1 schematically shows a tool according to he invention during the lowering into a chimney, Fig. 2 schematically shows the same tool during th© cleaning of the chimney of soot coatings, Fig. 3 is a sectional view of a rotor head with chains according to the invention, Fig. 4 schematically shows u tool used by the method according to the invention for increasing the width in the clear of a chimney in comparison with the original one, Fig. 5 is a sectional view along the line a-a in Fig. 4 in a chimney with traditional brick-built construction, Fig. 5 is a sectional view along the line b-b in Fig. 4 in the chimney in Fig. 5 after the increasing of the width in the clear and insertion of a lining and casting, Fig. 7 ie a sectional view corresponding to same in Fig. in a chimney of tile concrete elements, Fig. 8 is a sectional viaw corresponding to same to Fig. in the chimney shown in Fig. 7, Fig. 9 is a sectional view corresponding to same in Fig. 5 in a chimney of light concrete elements, and Fig. 10 is a sectional viaw corresponding to same in Fig. δ in th© chimnay shown in Fig. 9. - 9 From Fig. 1 and 2 it appears how the tool is used for th© cleaning of a chimney 1. Reference number 2 indicates a coating of tarry deposits on the internal surfaces of the chimney 1. Moreover, a driving unit 3 is shown, which is advantageously ca electric hand drill. The driving unit 3 is connected with a flexible shaft 6 by means of an elastic coupling 7 which can be disconnected. The driving unit can advantageously be located on the roof, as the flexible coupling 7 as well as the distance between the guiding unit 3 and the chimney 1 has the effect that during operation the guiding unit 3 will not be moving on the roof. The flexible shaft δ is in th® opposite end connected to a rotor head 4, on which ar® mounted a numb©r of chains 5. In Fig. 1 it is illustrated, how the rotor head 4 with chains 5 can be lowered into a chimney 1. An opening of substantially the same else as the rotor head 4 is sufficient in order that th® chimney may be cleaned. AFter having lowered the rotor head 4 right down into the chimney 1, the driving unit 3 is started. Th® chains 5 will be slung against the internal surfaces of the chimney 1 and will process these with series of strokes. Hereby the coating 2 will be milled out and broken. By taking th© rotor head 4 through the chimney 1, said chimney will be effectively cleaned of internal coatings 2.
All connections between th® driving unit 3, th© flexible shaft 6, th© rotor head 4 as well as th© rigid extension shafts 8 are made by means of couplings known per se that can be disconnected.
Xn Fig. 3 a more detailed rotor head 4 is shown, on which ar© mounted four chains 5, same having an odd number of links, end same being firmly fixed through tha central links. Xt is of course possible to use a different number of chains 5, just es these may be connected to th© rotor head in various manners known per ae, as long as they ar© firmly fixed. Th© chains 5 are advantageously made from iron or similar strong and heavy material, for instance hardened steel, and preferably they have a gauge of metal of 5—6 ma. The outermost links may, if desired, contain diamond dust, which is of particular importance if part of a concrete material is to be removed.
When eight chains being located crossed above each other are * used, a height of the chain pile of approximately 10 cm is typically obtained. k In practical experiments the method according to the invention has turned out to be superior to all known methods for the cleaning of chimneys, as the cleaning of a chimney becomes substantially more rapid by the method according to the invention than it was previously possible.
In Fig. 4 is shown th® tool according fo th® invention for use by the method according fo the invention for milling a chimney, in order that the width in the clear is increased.
In order fo centre the fool in a chimney, same tool is provided with a guiding unit 15, through which the flexible shaft 6 has been conducted. The guiding unit is located immediately above the rotor head 4 and may have the form of a tube section, same af its ends being provided with tv?o truncated cones, and with a hole through if.
The diameter of the guiding unit is preferably somewhat smaller than the width in the clear in the chimney, the width of which is to be increased, said guiding unit for a chimney flue with a width in the clear of 15 cm having for instance a diameter of 14.5 cm. Adjusting the length of the chains 5 determines how much is to be milled off.
In this manner e.g. an Iso-kaem'^lining may be milled, removing both the inner tube and the Leca-casting while leaving the chimney itself, and using as driving unit a more powerful engine than for the removal of soot. Th®n, in the usual manner a new lining can be inserted. The tool may also - 11 be used for the removal of th© interior of an &ikl"-chimney or a ^sminent^-chimney. By the removal th© lining is pulverized and drops to th® bottom in the chimney, So 2&r it * has not been possible selectively to remove a lining in a chimney, either after a fire or if an increase of the width in the clear of th® Ghimney is required out of consideration for d another application than the original.
When the tool is used for increasing the width in the clear of a chimney, it is of course obvious that more energy than by soot removal must be used, and in this cms a driving unit in the form of an electric motor or a combustion engine, e.g. an engine ranging up to 3.7 Kw (5 HP) would bo suitable. Λ 1.5 tew (2 HP) electric motor may for instance be U£J®d.
When using th© method and the tool for the removal of coatings IS such as soot, the rotor head is lowered into th© chimney, whereupon the rotation is started.
It c&n easily b® heard when the chains have removed the soot and then hit the inner wall of the chimney, whereupon the tool may for instance by pulled upwards until it processes a coating surface again. For the removal of for In^tanesSs soot coatings it in possible to hold the tool with the hand, as th® cleaning is rapidly done and the tool is light.
When it is required, as shown in Fig. 4, to incre&si® th® width in th© clear of a chiansy, it is advantageous to mount a rack 25 27 with a wheel IS, over which the fletxibla shaft 6 is conducted, and th© engine 7 nay be placed on the roof- An advantageouiS method ia this case is to lo^r th© tool right down to the bottom of the chimney, th© width of which is to be increased, and then start up there, the chain length b®inc 30 adjusted to th© required now width in the clear. Th© tool is started, and when it can be heard that it runs at idle sp©«sd" it is pulled upwardly until again the* chains c&tch1* an inner surface which is to be removed, and at the same time the tool is guided by the guiding unit 15. It is advantageous at the same time to remove the milled off or pulverized material with a vacuum cleaner at the bottom of the chimney, thereby to a large extent avoiding the inconveniences of dust for the person doing the work.
Figs. 5,7 and 9 show a sectional view along the line a—a in Fig. 4 in three chimneys of a traditional brick-built construction, of file concrete elements and of light concrete elements, respectively, and Fig. 6, 8 and 10 show a sectional view along the line b—b in Fig. 4 after milling" of the chimneys shown in Figs. 5, 7 and 9, respectively, and insertion of a chimney lining, e.g. an iso-k&ern-chimney lining, and after casting around the lining with a mass, e.g. Leca-concrete. As lining may also, if desired, be inserted a steel lining, and for the casting around the lining may also be used granulated rock wool, e.g. "RockwooI-granulate mixed with water or a product called Fibo, corresponding to "Leca.
The chimney shown in Fig. 5, built of bricks 17 with mortar joints 18 may according to the method be given a smaller width in the clear by inserting a chimney lining. The lining 19 shown in Fig. 6 can not be inserted in the chimney until the width in the clear has been increased to such an extent that if corresponds to a hole with limiting surfaces 20, whereupon the void around the lining 19 is filled with e.g. Lecaconcrefe 21.
Figs. 7 and 8 show the insertion of a chimney lining 19 in a chimney made of file concrete elements 22 after removal of the inner parts 24 of the element 22 to such an extent that there is room for a lining 19. After inserting the lining the void around the lining is filled with a mass 21. - 13 Figs. 9 and 10 show in an analogous manner as Figs· 7 and 8 an embodiment of the invention, where a lining 19 is inserted in a chimney of light concrete elements 25 after removal of aa inner part 26 thereof and casting of the void around the lining 19 with e.g· Leca-concrete 21.
According fo the invention if is thus possible to increase as well as reduce the width in the clear of an existing chimney or to insert a lining in a chimney while keeping the existing width in the clear without having to resort to chimney breaking and rebuilding. The insertion of a lining and the casting around th© lining are carried out in a manner known per se, when space for this has been created in the chimney.
The ML&ca-concrete used is preferably made as followss Prewatered Leca-peas with the diameter of 3-10 mm are mixed with cement in the ratio of ls20. After thorough mixing more water is added until the mixture obtains a ground-moist consistence, and this mixture is carefully poured into the void around the lining without tampering.
