Definitions
- This invention relates to apparatus for drying extensive surfaces.
- Road markings are laid as a hot molten thermosetting plastics compound, which includes a filler. As the compound cools it sets to a solid which is intended to adhere to the surface of the road. Unfortunately, even a very small amount of moisture on the road surface prevents the adhesion so that many working hours are lost each year while road marking gangs wait for the surface to dry.
- One attempt to dry the surface involves a hollow lance with a plenum chamber at one end from which open a series of small orifices. Air under high pressure is supplied to the plenum chamber by a compressor which is readily available to a road working crew.
- the plenum chamber is also supplied with a fuel, e.g. propane, which is burnt in the compressed air in the chamber.
- propane e.g. propane
- apparatus for drying extensive surfaces comprising an air knife directed at the surface, the air knife comprising one or more nozzles which has or have an outlet comprising an elongate slot ; means for delivering air to the nozzle(s) at a high volume flow rate and low pressure, the total cross sectional area of the nozzle(s) at its or their outlet being approximately equal to the cross sectional area of the outlet of the blower means for delivering air through which the outlet air is delivered, said apparatus either including means for transporting the entire apparatus across the surface, or being attached to a plant for treating the dried surface.
- the arrangement efficiently strips water off the surface and the noise may be kept down to a level acceptable to the work force.
- the apparatus may be used to clear surface water from roads, or sports areas before laying tarmac or markings, or for drying pitches whether grass or synthetic. Other uses may well occur to the reader.
- a much preferred embodiment of the invention includes an arrangement to heat the air supplied to the nozzle. Surprisingly, sufficient heat can easily be provided to dry the surface completely, or sufficiently to lay road markings.
- the means for delivering air to the slot includes a blower driven by a motor mounted in or on the apparatus.
- the blower can be a standard product.
- the motor may be a petrol or diesel unit.
- the arrangement to heat the air preferably includes a heater comprising a chamber, a burner to burn fuel in said air in the chamber, and means mounted in or on the apparatus for storing the fuel and supplying it to the burner.
- a heater comprising a chamber, a burner to burn fuel in said air in the chamber, and means mounted in or on the apparatus for storing the fuel and supplying it to the burner.
- Previous proposals for air knives to use heated air have used electric heaters. That may be adequate for static apparatus in a factory environment, but is not suitable for mobile apparatus which is moved across extensive surfaces, e.g. many miles of roadway preparatory to marking a line or sealing a slot or groove.
- a jet engine constitutes both the arrangement to heat the air and also the means for delivering air to the slot.
- the engine may be a fan jet.
- the apparatus may be automotive or mounted on, say, wheels so that motive power is provided by a pedestrian.
- thermosetting compound may comprise tarmac or a compound for marking lines on the surface.
- a road marking vehicle 2 having road wheels 4, is driven by an engine 6, and is controlled by an operator seated at a position 8 where a steering wheel 10 and other controls are located.
- the vehicle has a heated hopper 12 for the thermosetting compound to be laid, and a laying head 14, for example an extrusion shoe (illustrated) or a screed box.
- the laying head is selectively operated to lay the compound on the road so as to provide the desired markings.
- the vehicle illustrated additionally has three air knives 20, illustrated generally in Figure 1 and more particularly in Figures 2 and 4 and 5.
- the air knives 20 are directed downwardly and forwardly at the road 22 ahead of the track that the laying head will follow.
- each air knife comprises a cylinder 24 closed at each end to provide a plenum chamber 26.
- An outlet is provided in the form of a rectangular slot 28 between plates 30 which direct air at high volume and low pressure downwardly and forwardly at the road 22.
- the plates should be manufacture to resist distortion from the high temperatures which will be obtained by the heating arrangement to be described.
- the plates are manufacture from thick plates of high grade stainless steel and, additionally, are bridged at intervals by weld so as to maintain their spacing.
- An inlet manifold 32 is provided in the form of a tapering tube to supply air to the plenum chambers. At its inlet end the manifold has a cross sectional area approximately equal to the total cross sectional area of all three slots 28. The manifold tapers towards the most forward of the air knives so that at its most forward end, it has a cross sectional area approximately equal to the area of the slot of that air knife. At the intermediate air knife the manifold has a cross sectional area approximately equal to the area of the outlet slots of two air knives.
- the air knives 20 are mounted in a frame 40 which is supported above the road by four castors 42 so that the air knives are positioned a predetermined distance from the road surface.
- the frame 40 is attached to the vehicle by arms 44 pivotally connected at one end to the vehicle (not shown) and at the other 46 to the frame. The air knives are thus moved along the road by the vehicle ahead of the laying head.
- the manifold inlet 34 is connected via a heater 54, and a flexible pipe 52 to the outlet of a blower unit 56.
- the cross sectional areas of the pipe 52, and thus the manifold inlet 34 and the total area of the slots 28, are chosen each to approximately equal the cross sectional area of the outlet 58 of the blower 56.
- the blower is driven by a petrol engine 60, the two being mounted on a platform 62 attached to the vehicle.
- a cross section of the heater is shown in Figure 3.
- the heater has a chamber 70 which expands from an inlet 72, which has a cross sectional area equal to that of the pipe 52, to a larger cross sectional area in which a burner 74 is mounted by a perforated conical support 76.
- Propane, or in other examples other fuel is supplied to the burner from a container 78 mounted at the rear of the vehicle.
- the fuel is ignited by a spark plug 80.
- a flame failure device including a sensor 82 operates to cut the fuel supply if the temperature drops indicating the flame has gone out.
- the chamber 70 reduces in cross sectional area to match that of the inlet to the manifold 32.
- Operation of the engine 60 to drive the blower 56 produces a high volume flow of low pressure air at the air knives 20 distinct, say, from the low volume high pressure air supply which is provided by a compressor.
- the air knives will clear loose water from the road as the vehicle is driven at a surprisingly high rate. Without operation of the heater the road would remain damp, although free of loose water, and prevent the adhesion of road marking compound.
- the drying apparatus may have utility in other applications, however.
- One example is to clear loose water from, say, a sports pitch or race track.
- Operation also of the heater will dry the surface more or less completely: sufficient to allow road markings to be laid. In one example we found the temperature of the air at the outlets of the air knives to be about 750°C.
- FIG. 6 An another example is illustrated in part in Figures 6 and 7.
- the main difference is an improved burner 74.
- this is in the form of a ring burner from which we have obtained a temperature at the outlets of the air knives of about 900°C.
- the low pressure high volume air could be both provided and heated by a fan jet.
- the apparatus may be controlled by, or pushed by, a pedestrian operator.
- a pedestrian operator Such an arrangement is illustrated in Figure 8.
- the primary function of the apparatus is to dry the surface, e.g. the road 22.
- Subsequent treatment of the surface e.g. marking with a line, sealing a slot or groove, laying tarmac etc, would be carried out separately by hand or by another machine not illustrated.
- the apparatus is mobile, having a tubular chassis 100 supported on a pair of wheels 102, rotatable about a common axis, and a pair of castor wheels 104.
- the burner 54, pipe 52, blower 56, engine 60 and gas supply 78 are mounted on the chassis 100 and are similar to those of Figure 1, except that the engine is gas fuelled from the same supply 78 as the burner.
- the specific arrangement of air knives is different in that a manifold 106 feeds heated air to two air knives 20 mounted one behind the other.
- Other pedestrian control apparatus may be automotive and/or may include equipment for treating the surface, e.g. for making a road with lines.
