Definitions

  • the invention relates to a method for increasing the width in the clear of a chimney by means of a rotary tool having 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 e.g. of simple, elongated, ring-shaped chain links, which are fixedly mounted on several levels at right angles to the rotatable shaft.
  • FR-A-707,546 discloses a method for increasing the width in the clear of a chimney by means 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.
  • the method of the invention should allow not only to remove existing 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 tube can be inserted in the chimney.
  • 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value than that of the original width in the clear, that the material pulverized during the reaming operation is withdrawn at the bottom of the chimney, for instance by a vacuum cleaner, that a lining of an internal diameter corresponding to the original width in the clear is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.
  • the tool For starting the reaming of the chimney or the object concerned from the bottom, the tool is pulled up through the chimney. If, on the other hand, the tool should be inserted from the top of the chimney, it had been necessary to subject the flexible shaft to a pressure in the longitudinal direction thereof, whereby the shaft would easily be deflected with detrimetal consequences. Also, the reaming operation according to the invention is conveniently started in that the tool can be guided in the original width in the clear of the chimney.
  • the material removed by the reaming operation can drop freely through the widened width in the clear of the chimney to the bottom thereof, whereas when engaging the tool from above, the material removed would have remained on the rim between the original width in the clear and the widened one and would embarrass the rotation of the tool.
  • the rotary tool can easily be lowered in the chimney since owing to its radially yieldable means, it occupies such a radial dimension that it can be descended through the chimney.
  • the material milled off from the interior of the chimney becomes completely pulverized if this material is brick or a conventional chimney lining material while, when being concrete from the chimney top slab, it will be broken into relatively small fragments. It is then possible to withdraw the pulverized material at the bottom of the chimney by means of a vacuum cleaner or like apparatus.
  • the necessary lining can conveniently be inserted in the smoothly milled chimney, whereupon the remaining void between the outer side of the lining and the 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. This 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
  • 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.
  • the use of chains on several levels, preferably eight, at right angles to the rotatable shaft ensures adequate processing of a suitably large zone in a chimney as the chains simultaneously support each other in a 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.
  • chains consisting of a hard and heavy material, for instance hardened steel, the uttermost chain links optionally containing. diamond dust, and to 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 to process the inner side of the chimney with the force of impact required.
  • 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 the chimney and which has a pulley for guiding the flexible shaft, so as to achieve a simple way of operating the rotary tool.
  • FIG. 1 schematically shows a tool according to the invention during the lowering into a chimney
  • a guiding unit 3 is shown, which is advantageously an electric hand drill.
  • the guiding unit 3 is connected with a flexible shaft 6 by means of an elastic coupling 7 which can be disconnected.
  • the guiding 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 6 is in the opposite end connected to a rotor head 4, on which are mounted a number of chains 5.
  • a more detailed rotor head 4 is shown, on which are mounted four chains 5, same having an odd number of links, and same being firmly fixed through the central links. It is of course possible to use a different number of chains 5, just as these may be connected to the rotor head in various manners known per se, as long as they are firmly fixed.
  • the chains 5 are advantageously made from iron or a similar strong and heavy material, for instance hardened steel, and preferably they have a gauge of metal of 5-6 mm.
  • the uttermost 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.
  • Fig. 4 is shown the tool according to the invention for use by the method according to the invention for milling a chimney, in order that the width in the clear is increased.
  • 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 at its ends being provided with two truncated cones, and with a hole through it.
  • 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.
  • an "Iso-kaern"-lining may be milled, removing both the inner tube and the Leca-casting while leaving the chimney itself, and using as driving unit 3 a more powerful engine than for the removal of soot. Then, in the usual manner a new lining can be inserted.
  • the tool may also be used for the removal of the interior of an "Anki”-chimney or a "Kaminent”-chimney. By the removal the lining is pulverized and drops to the bottom in the chimney. So far 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 the chimney is required out of consideration for another application than the original.
  • a guiding 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 be suitable.
  • a 1.5 kw (2 HP) electric motor may for instance be used.
  • the rotor head When using the method and the tool for the removal of coatings such as soot, the rotor head is lowered into the chimney, whereupon the rotation is started.
  • soot coatings it is possible to hold the tool with the hand, as the cleaning is rapidly done and the tool is light.
  • 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 tile concrete elements and of light concrete elements, respectively
  • 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-kaern"-chimney lining, and after casting around the lining with a mass, e.g. Leca-concrete.
  • a chimney lining e.g. an "Iso-kaern"-chimney lining
  • 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. "Rockwool”-granulate mixed with water or a product called “Fibo", corresponding to "Leca”.
  • Rockwool granulated rock wool
  • 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 it corresponds to a hole with limiting surfaces 20, whereupon the void around the lining 19 is filled with e.g. Leca-concrete 21.
  • Figs. 7 and 8 show the insertion of a chimney lining 19 in a chimney made of tile 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.
  • 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 an inner part 26 thereof and casting of the void around the lining 19 with e.g. Leca-concrete 21.
  • the "Leca"-concrete used is preferably made as follows: Pre-watered Leca-peas with the diameter of 3-10 mm are mixed with cement in the ratio of 1:20. 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.
