Definitions

the invention relates to a method and apparatus for sealing chimneys.
a third known technique involves inflating a rubber former within the chimney, the former having the shape of a long thin balloon.
the liner is held clear of the chimney walls by steel spacers and a heat resistant sealing compound is then pumped into the chimney filling the space around the liner.
our invention provides a method of sealing a chimney, comprising positioning a spray device within the chimney, spraying sealant from the spray device onto the internal walls of the chimney and moving the spray device along at least a part of the length of the chimney.
the spray device is moved along the entire length of the chimney, but where leakage from the chimney is only a problem over part of the length of the chimney, then the method may be used merely to seal this part.
the invention includes apparatus for sealing a chimney, comprising a spray device positionable within the chimney, and operable to spray sealant from the spray device onto the internal walls of the chimney, and means for moving the spray device along at least a part of the length of the chimney.
the means for moving the spray device may comprise a sealant feed pipe by means of which the spray device can be lowered down a chimney.
the spray device may have a rotatable spray head to throw sealant out onto the internal walls of the chimney.
Means may be provided to guide the spray device along the length of the chimney.
the guide means may be arranged to centralise the spray head in the chimney.
the guide means may comprise a sledge having a plurality of skids spaced apart around the spray device, each skid being arranged to contact a part of the wall of the chimney.
the spray device may be operated by compressed air.
feed pipes There may be two feed pipes, one to feed the sealant and one to feed compressed air.
the sealant may be fed to the spray device by a sealant pump.
centralising sledge may be provided to suit different diameters of chimney.
the size of the sledge may be adjustable.
the sledge may for example be adjustable to suit chimneys having diameters of 6", 9" and 12".
a preliminary adhesive may be sprayed onto the internal walls of the chimney, to assist the bonding of the sealant to the chimney walls.
the invention includes chimneys when sealed using the method or apparatus according to the invention.
the invention includes a spray sealant for use in sealing chimneys.
the sealant may comprise 45% to 65% by volume of calcined alumina, 25% to 35% by volume of silica sand/flour, 7% to 15% by volume of plastic ball clay, reduced to a powder, and 4% to 10% by volume of a binder.
the binder may comprise soluble silicate powder.
the particle size of the calcined alumina may be 60 mesh.
the particle size of the silica sand/flour may be 30 mesh.
Figure 1 shows a typical brick built chimney 10, one leaking joint being shown, by way of example only, at 11.
an entire chimney can be defective, for example because of broken or faulty mortar, and cracked or porous brickwork.
the apparatus comprises a compressor 12, a sealant pump 13, an air line 14, a delivery hose 15, a spray device 16 having a spray head 17, and a centralising sledge 18.
the compressor is connected to the spray device 16 by the air line 14.
the sealant pump 13 is releasably connected to the spray device 16 by hose couplings 19 and 20.
the spray head 17 is arranged to rotate at high speed on the spray device 16, driven by a compressed air motor within the spray device. Rotation of the spray head, coupled with pumping of the sealant under pressure into the spray head, causes sealant to be sprayed out onto the internal walls of the chimney 10.
an adhesive spray nozzle is initially lowered down the chimney to spray preliminary adhesive over the internal walls of the chimney. This increases the degree of bonding between the sealant and the chimney walls.
the spray device 16 is lowered down to the bottom of the chimney by means of the delivery hose 15.
the compressor 12 and sealant pump are then started, and as the sealant sprays out of the spray head 17, the device is gradually hauled back up the chimney until the entire length of the chimney is sealed.
only a limited length of the chimney may be sealed if there is a single readily identifiable problem in a particular area.
adjustable skids 21 of the sledge 18 are moved to a position in which they lie adjacent to the internal walls of the chimney, with the spray device 16 centrally positioned between the skids.
the chimney sealant compound comprises 45% to 65% by volume of 60 mesh calcined alumina, 25% to 35% by volume of 30 mesh silica sand/flour, 7% to 15% by volume of plastic ball clay reduced to a powder, and 4% to 10% by volume of soluble silica powder.
the apparatus as shown in the Figure is used, except that the delivery hose 15 is connected to the adhesive spray nozzle, instead of to the spray device 16.
a hopper 22 on the sealant pump is filled with a sufficient quantity of adhesive. The nozzle is initially held over the hopper 22, the pump is turned on, and then the speed of the pump is regulated until a good spray pattern is exhibited. During this test period, the adhesive sprays back into the hopper.
the pump is then turned off, the nozzle is taken to the top of the chimney, and is inserted in the top of the flue.
the pump is then turned on again, and the nozzle is lowered slowly down the flue, making sure that as much of the flue is sprayed as is possible.
the pump 13 and delivery hose are then washed out ready for use in applying the sealant.
One embodiment of adhesive that may be used is a soluble silicate liquid, compatible with the chimney sealant compound.
the pump and compressor should be set up on level ground as near as possible to the chimney.
the spray device 16 is reconnected to the pump using the delivery hose 15 and the air line is connected between the compressor and the spray device.
the compressor 12 is turned on with its outlet valve closed.
the mixed sealant is then loaded into the hopper 22 and pumping continues.
the spray head 17 is initially positioned in a bucket to collect the water as it is pumped through the system and the pump is then switched off.
the spray head 17 is then held in or above the hopper 22 and the pump 9 is switched on again until pump sealant runs out of the spray head into the hopper.
the air valve on the compressor 12 is now opened and the spray pattern exhibited by the spray head 17 can be inspected.
the compressor is then adjusted to vary the pressure until a satisfactory spray pattern is produced. It has been found that the optimum pressure is somewhere between one bar and five bar, for example two bar.
the sealant should be allowed to pump back into the hopper for about three to four minutes to ensure that there is nothing in it that will block the spray head.
the pump and air supply are then switched off, the spray head is taken to the top of the chimney and is lowered down inside it.
the pump and air supply are then switched on again and spraying proceeds as already mentioned in the general description above.
the spray device 16 may be moved along the chimney more than once, to ensure full coverage.
skids 21 should be set at a diameter 1" less than the internal diameter of the chimney.
the sledge comprises a metal cylinder 24 which is about 100 mm in length.
the spray head 17 can be secured within this cylinder by means of fixing bolts 25.
lugs 26 At one end of the cylinder, there are four lugs 26, spaced apart at 90° intervals.
the internal diameter of the cylinder is about 50 mm.
Each lug 26 has a hole 27 therein.
each lug 26 has'bolted thereto a pair of arms 28 and each arm carries at its free end a rotatable wheel 29.
the arms are secured to the lugs by a bolt which passes through holes 30 in the arms and hole 27 in the associated lug.
a butterfly nut (not shown) is secured to the boIt.
each end of the sledge is supported by four wheels which engage with the internal wall of the chimney.
the overall external dimensions of the sledge can be adjusted to suit many sizes of chimney.
the spray head is arranged to project from the lower end of the cylinder 24 to appoint lying below the lower wheels 29, so that the wheels do not hinder the spray pattern emerging from the spray head.
