Definitions

  • the invention is concerned with improvements in or relating to apparatus for applying marking marterials to road surfaces.
  • Various apparatus for applying marking materials to road surfaces such as highways and airport runways are known. These include arrangements in which a supply of the marking material is preheated to melt a constituent of the material and is then applied to a surface to be marked by passing through insulated pipes to an applicator.
  • This method suffers the drawback that it involves a high capital outlay on the apparatus for heating the marking material in bulk and maintaining it at an appropriate temperature until it is applied. This is usually done by employing two vehicles one carrying the bulk supply of material and the other the applicator apparatus, although one large vehicle may suffice.
  • Devices for spraying particulate materials to form coatings on substrates are a19 0 known and include "flame" spray devices or apparatuses which are normally used to apply coatings of refactory material and the like.
  • "flame" spray devices for example as shown in British Patent 1109481 it is usual for the particulate material to be subjected to the direct effect of a flame.
  • This has the disadvantage that, where materials with low melt temperatures are subjected to the direct effect of the flame, great care has to be taken to ensure the accuracy of the residence time of such materials in the flame if charring of the materials is to be avoided.
  • high melt temperature materials are subjected to the heating effects of combustion gases there often has to be some additional heat supply in order to achieve the desired results.
  • pre-heating of the highway surface to between 65.6°C and 260°C is advocated.
  • French Patent 2155837 It is also known from French Patent 2155837 to provide in accordance with the first part of claim 1 an apparatus comprising means to burn a gaseous fuel under pressure to provide a supply of heated pressurized gas, duct means to direct the hot gas onto the road surface to be marked and means to inject a supply of marking material in unfused form into the hot gas stream within the duct means downstream of the burner means, thereby to cause the marking material to impinge on the surface.
  • the apparatus is generally T-shaped with the short arm of the T arranged vertically and the burner means in the longer arm arranged to direct the hot gas stream along that arm and down thp lower part of the shorter arm.
  • Both arms of the apparatus are cylindrical and the marking material is put into the hot gas stream through the upper part of the shorter arm of the apparatus so that it is entrained in the hot gas stream for a very short period or it falls to the surface.
  • the apparatus is described as a road marking apparatus it is wholly unsuitable for this purpose because the geometry of the apparatus does not ensure either a reasonable residence time for the marking material in the hot gas stream or any control over the stream of marking material applied to the surface.
  • the short cylindrical outlet duct of the apparatus could not produce satisfactory road markings.
  • the T-shaped arrangement with the material mixing with the hot gas stream as that stream is turned through 90° would result in wholly unsatisfactory distribution of material in the gas stream.
  • the present invention seeks to overcome these problems and provide an arrangement in which the marking material is directed onto the surface in a controlled manner and in such a way as to ensure satisfactory markings with clearly defined edges.
  • the duct means comprises a first elongate mixing chamber portion down which the hot gas is directed and into which the marking material is injected and a second elongate outlet duct portion co-axial with and downstream of the first portion, the outlet duct portion being of rectangular cross-section and having a ratio of length to maximum cross-sectional dimension of at least 4.75:1 so that the distance of the point of injection of the marking material from the road surface to be marked is such that at least some of the marking material is fused before the marking material impinges on the surface.
  • the outlet duct may be provided with baffle means whereby, when the apparatus is in use, oscillation of the material is prevented thereby obviating accretion of the material to inner walls of the duct.
  • the material is injected by feed means which may comprise at least one inlet port arranged so that material is injected into the hot gaseous jet upstream of the duct.
  • the material is injected into the hot gaseous jet upstream of the duct as aforesaid at an acute angle to the direction of the jet.
  • the acute angle may be up 70° but is preferably 35°.
  • the feed means may also include a fluidised bed arrangement for feeding material to the inlet ports.
  • the feed means may be controlled by means which may be manually operated or may be operated automatically in response to actuation of sensing means.
  • the burner is a flash back burner utilising liquefied propane gas as a fuel and in a preferred apparatus provided by the invention the burner may be connected to the duct through a swirl chamber for damping unwanted oscillations in the exhaust gases from the burner.
  • the ratio of the length of the outlet duct to its maximum cross-sectional dimension is preferably between 4.75:1 and 9:1 and may be approximately 6.5:1.
  • Apparatus used hitherto, for the application of markings, to highways or airport runways, etc., has not always resulted in a well defined durable marking at an acceptable speed of application or an acceptable cost per unit area covered by the marking.
  • the apparatus shown in the drawings enables a layer of a marking material to be sprayed onto a highway, airport runway or the like, with great economy in material usage, at low power consumption and with minimum interruption of traffic flow.
  • the apparatus comprises a bulk storage hopper 10 from which particulate marking material 11 may be fed via a screw elevator 12 to a fluidised bed feed device 14 and then via a line 16 to a mixing tube 18 where the material 11 is injected into a hot gaseous jet, created by a burner 20, before passing along a duct or flight tube 22 to be sprayed onto a highway 24, as shown at 26, to form a marking on the highway 24.
  • the material is injected into a reduced atmosphere.
  • the bulk storage hopper 10 is fed with compressed air from compressor 34 via a line 33 and control valve 31, so that the marking material 11 forms a fluidised bed.
  • the hopper 10 can usefully have a capacity of between one and six tonnes depending upon the size of vehicle on which the novel apparatus is to be used.
  • the screw elevator 12 ideally has a feed rate of between one and fifteen litres per minute and feeds the particulate marking material via a duct 13 to the feed device 14.
  • the feed device 14 has a capacity for 200 kilos of the particulate material fed thereto and comprises a container 30 fed with compressed air to form a fluidised bed. The compressed air is fed from compressor 34 via a line 33 and control valve 32 into the base of the container 30.
  • Material in the container 30 is ideally maintained at a level indicated by the dotted line 35.
  • a level switch 36 provided on a side wall 37 of the container 30, is connected to a motor 38 whereby rotation of the screw elevator 12 is effected in response to movement of a float member 39 forming part of the valve 36.
  • the feed device 14 also comprises a venturi valve 40 connected to the line 16 inside the container 30 which valve 40 is controlled by an actuator 41 whereby the rate of feed of particulate material through the valve 40 may be adjusted or shut-off as required.
  • the actuator 41 is in turn controlled pneumatically, via a solenoid controlled valve 42, from an appropriate control console 72 which may be mounted at any convenient location.
  • the disposition of the venturi valve 40 and the line 16 within the container 30 is consistent with obtaining a flow of the particulate material which is of an acceptable range of particle sizes, i.e. the particulate material will only show small diversities in size over a given period.
  • This is achieved by positioning the valve 40 and line 16 at an optimum level within the container. This occurs because the effect of the fluidised bed 11 is to stratify the particulate material in the container 30 according to the size of granule. Large granules will be more prevalent towards the top of the container and small granules towards the bottom. Thus, at an optimum level the ideal size range of granule can be expected.
  • a pigment feed hopper 44 On the outlet side of the line 16 between the container and the mixing tube 18 there is shown a pigment feed hopper 44 see Figure 3.
  • hoppers 44 there may be two or more hoppers 44 and switching of appropriate venturi valves located within the hoppers 44 enables the desired pigment to be fed into the flow of particulate material in the line 16.
  • the mixing tube 18, see Figure 3 is provided by a tubular chamber, 46 of circular cross section connected at an upper end portion 47, thereof to a combustion chamber 48.
  • the combustion chamber 48 is in turn connected to the outlet end 49 of the burner 20, see Figure 8.
  • the burner 20 may be a commercially available flash back burner using liquid propane gas and air mixture as fuel.
  • the air is supplied via a line 52 from the compressor 34 and the gas is supplied via lines 53 from liquid petroleum gas storage tanks 54, see Figure 3.
  • a spark generator 55 is provided to initially ignite this fuel mixture.
  • This combustion chamber consists of two coaxial cylindrical tubes 57 and 59.
  • the inner tube 57 has two rings of ports 58, which allow the air, fed via line 51 into the passage between tubes 57 and 59, to pass into tube 57 to react with any unreacted fuel.
  • These ports 58 are set at an angle, as shown, so as to introduce the air into tube 57 with a component of velocity in the direction of the general velocity of the gases already in the tube.
  • the mixing tube 18 is connected to the flight tube 22 by a suitable adaptor, not shown.
  • the length of the flight tube 22 is chosen so that the particulate material, which is admixed with the hot gaseous jet in the mixing chamber 18, will remain in the flight tube for a sufficient time for enabling sufficient heat transfer from the gaseous jet to a heat softenable portion of the particulate material to substantially liquefy said portion.
  • the ratio of the length of the tube 22 to its maximum cross-sectional dimension (width) is approximately 6.5:1.
  • flight tube 22 The actual dimensions of the flight tube 22 will be chosen to suit the application, the particulate material, the feed rate of particulate material and the capacity of the burner 20. Thus, in Figure 5 and 6 there are shown two further flight tubes 22a and 22b having length:width ratios of 9:1 and 4.75:1 respectively.
  • the flight tube 22 is also shaped to give a lamella flow of particulate material therefrom.
  • the tube 22a is rectangular in cross-section and of constant dimensions along its length while the tube 22b of Figure 6 is of variable cross-section along its length, being approximately square at its upper end and tapered in one dimension and flared in the other from that end to its lower end.
  • the rectangular shape of the outlet end of the flight tube helps to ensure that markings applied by the apparatus do not have blurred edges.
  • the flight tube 22 is of constant dimension along its length and no great difficulty is encountered in obtaining a true lamella flow of material from a nozzle end 25 thereof.
  • baffle plates may be provided down the centre of the flight tube 22 to split the tube in two length-wise. Indeed several baffles may be provided splitting the flight tube along its length into several parts. Tests on such arrangements have shown that the resultant markings are not impaired in any way while accretion of material to side walls of the flight tubes 22 is prevented.
  • Such alternative methods may include the use of annular inlet ducts for introducing hot gas to the tube 22 to augment the flow of the gaseous jet therethrough. Accretion is also prevented by lining the flight tube with a perforated lining plate, which also has the advantage of reducing the noise of the operation.
  • the apparatus may also include purging means for purging the apparatus of particulate material at the end of work shift.
  • This purging means may comprise a container for cleaning grit, sand, or the like material. This material may be fed into the feed device 14 via a venturi valve similar to valve 40.
  • air from the compressor will cause cleansing material to be fed to the mixing chambers 18 as aforesaid, via the valve 40 and line 16 to purge the mixing chamber 18 and flight tube 22 of any residual particulate material.
  • the purging means may also comprise a fluidised bed for agitating the sand in the container.
  • a material such as small glass beads onto the road 24 to form a top reflective layer of the marking 26.
  • These beads are held in a hopper 60, and may be agitated to form a fluidised bed.
  • To feed these beads to the road they are passed down a tube 61 and through a pneumatically controlled venturi valve 63 onto the road 24.
  • the apparatus described above may be adapted for mounting on a vehicle 80, see Figure 1 and 2, which vehicle is of much simpler design than known road marking vehicles.
  • FIG. 1 there is a laterally moving carriage 81.
  • This carriage includes a feed means 14, and a hopper 60 to hold glass beads and the like.
  • flight-tube there may only be one set of flight-tube, mixing chamber, feed line, combustion chamber and burner, all of which may be mounted as a boom to swing to either side of the vehicle.
  • This boom may be covered by a thermally insulating jacket to protect operative personnel from burns.
  • a gas deflector 86 may be attached to the lower end portion 25 of the flight tube 22. This arrangement is utilised to assist the adhesion and setting of the sprayed on marking 26.
  • the apparatus described above has several major advantages in determining suitable marking materials which it may utilise.
  • the binder resins In the conventional thermoplastic road marking materials, the binder resins must melt to a state of high fluidity to enable the overall composition to be sprayed or flowed (screeded or extruded) onto the road surface. This limits the types of resin, or polymer, which can be used, and also effectively limits the final performance of the road marking material. High fluidity results from relatively low molecular weight which in turn leads to low mechanical strength and toughness.
  • the materials capable of being used by the above apparatus do not have this limitation, in that it is apparently sufficient that individual- binder particles should melt in order to adhere .to the surrounding particles of filler, pigment, beads, etc.
  • binder polymers can be chosen of much higher molecular weight which give enhanced mechanical properties over existing thermoplastic compositions.
  • thermo-setting material is suitable not only for the use of thermoplastic materials, but also for thermo-setting materials.
  • a typical thermo-setting type would be an epoxy powder coating material which comprises an intimate blend of an expoxy compound and a reactant, which do not effectively react to give a polymer until a threshold temperature above 100°C is reached. If used in the above apparatus, such particles would melt to fuse into a coherent whole and a chemical reaction would occur to improve the mechanical properties still further.
  • a composition, particularly suitable for use in the apparatus described above to provide markings on highways or airport runways, etc., is one such as described in our Patent Specification GB-A-1344255 entitled “Improvements Relating to road marking.”
  • particulate material in other forms may also be used in the apparatus e.g. particulate materials in a liquid suspension are envisaged.
  • the vehicle 80 may incorporate any convenient sighting or sensing device for alignment of the flight tube 22 of the spraying apparatus over the portion of the highway 24 to be marked.
  • the vehicle 80 is driven along the highway 24 and a marking 26 applied thereto.
  • the thickness of the marking may be in the range 0.3-4.0 mm and is preferably in the range 0.5-1.5 mm.
  • the operation of the apparatus may be automatic in response of sensing of areas to be marked or the apparatus may be controlled manually from the console 42 by the vehicle driver. In either case the on-off cycle may be achieved by opening and closing the venturi valve 40 of the feed device 14 to interrupt the feed of the particulate material. In short line markings interruption of the burner operation is not necessary; however, in long line markings where long gaps are formed between the markings it is economical to shut off the burner 20.
  • the burner 20 creates a hot gaseous jet in a reducing atmosphere capable of raising the temperature of the particulate material without charring to above its melt temperature which, according to the heat softenable portion of the particulate material used, will be 100 to 400°C.
  • the heat generated by the burner 20 must therefore be in the order of 293 KW in order to provide sufficient latent heat in the hot gaseous jet to enable it to affect the particulate materials as aforesaid.
  • a flashback burner is used to create the gaseous jet.
  • a gas turbine or free piston gas generator may be used.
  • variable geometry flight tube as shown in Figure 9 might be employed rather than the fixed flight tubes described above in order to adjust the width of markings and form symbols such as arrows.
  • ingredients of the marking material need not all be injected into the flight tube at the same point and the aggregate, for example, could be injected upstream of the burner.
