  • Snow removal vehicle 10 includes a motorized vehicle or tractor portion 20, a snow capturing portion 30, a heating assembly 40 and a discharge portion 80. While the embodiment shown in the figures is indeed one particular embodiment suitable for removing snow in accordance with the present invention, it is noted that other embodiments may vary significantly from that shown in the accompanying drawings. For example, the embodiment depicted in the figures relates to a vehicle having a tractor trailer type design and configuration. However, it is contemplated to provide a more compact design by manipulating the various components accordingly.
  • Tractor portion 20 may be any type of motorized vehicle or automobile suitable for housing certain components of the invention and for providing the necessary power and motion to the overall system. As best shown in Figure 1, tractor portion 20 is similar to a tractor design often employed in a tractor trailer vehicle. Such designs are well known in the art. Essentially, tractor portion 20 preferably includes a motor (not shown) for powering the system, cabs 22 and 24 (best shown in Figure 2) for housing a driver, operator and certain instruments, control room module 26 and wheels or tracks 28 that are powered by the motor. In a preferred embodiment, the motor is a standard combustion engine fueled by gasoline or diesel. However, it is contemplated that certain embodiments may employ other types of motors, such as natural gas powered engines or the like.
  • wheels 28 are preferably set aft of cabs 22 and 24. This is a well known design often employed in larger vehicles to aid in turning and/or cornering.
  • cabs 22 and 24 are situated so that the aforementioned snow capturing portion 30 extends between them.
  • the two cabs are connected together by a control room module 26 thereby forming the command center of vehicle 10, the entire construction of which forms the portion of tractor 20 in which the majority of instruments are housed.
  • Module 26 is useful for arranging and storing certain aspects of the control system of tractor portion 20.
  • module 26 includes an access port or door allowing for the internal components of tractor 20 to be accessed.
  • the complexity of the system may require two persons to properly operate vehicle 10. For example, certain embodiments require an operator to sit in cab 22 and operate certain aspects of the system, while a driver sits in a cab 24 and is responsible for the driving aspects of the vehicle.
  • cabs 22 and 24 are one preferred construction of vehicle 10 that allows multiple persons to operate the vehicle.
  • both persons are provided with complete visibility in at least a straight forward direction and certain peripheral directions.
  • tractor portions 20 are envisioned which may allow for control of the system by a single person.
  • a cab may be offset from a snow capturing portion 30, or vision aiding devices may be employed. This will be discussed more below.
  • snow capturing portion 30 preferably includes a shovel 31 in communication with a conveyor 32.
  • shovel 31 is height adjustable allowing for varying heights of snow to be captured therein.
  • shovel 31 is capable of pivoting about point 33.
  • rotation of shovel 31 in a clock wise direction would decrease the amount of snow captured, while rotation in the opposition direction would increase the amount of snow captured. This is often necessary in the clearing operation of a rather deep snow.
  • vehicle 10 may not be capable of capturing the entirety of the depth of the snow in one pass.
  • shovel 31 may be adjusted to only capture a portion of the depth.
  • a snow depth probe 34 may be provided on the shovel. This probe may be linked to a suitable monitoring and control system in the aforementioned cabs or control module for monitoring by an operator or driver.
  • Conveyor 32 is preferably a drag conveyor that rotates in synchronization with the forward movement of vehicle 10, (at approximately the same linear speed as that of vehicle 10) .
  • snow captured with shovel 31 is thereafter pushed towards conveyor 32 by the constant forward motion of vehicle 10.
  • the snow is transported on a conveyor belt or the like 35, until it reaches the end 36 of conveyor 32.
  • the snow is preferably dropped into heating assembly 40.
  • a portion of heating assembly 40 includes an opening situated below end 36 of conveyor 32.
  • snow merely falls into this opening.
  • other embodiments are envisioned in which snow is delivered to heating assembly 40 in different fashions.
  • a portion of conveyor 32 may extend into heating assembly 40, thereby delivering snow directly therein. Such a design would aid in removing residual snow from adhering to the conveyor 32.
  • conveyor 32 may be housed in a conveyor enclosure 37. Such a housing should be properly sized and configured to allow the amount of snow captured by shovel 31 to move therethrough. It is contemplated that the combination shovel 31 and conveyor 32 assembly is but one fashion in which snow may be captured by vehicle 10. For example, in one embodiment, it is contemplated to utilize a screw type assembly (not shown) to grasp the snow and transfer such to an interior portion of vehicle 10. Further, it is contemplated to provide a different type of conveyor assembly, such as a belt conveyor, auger or the like.
  • FIG 4 is a flow diagram of a heating assembly 40 according to a preferred embodiment of the present invention.
  • Heating assembly 40 is preferably suitable for melting and heating captured snow so as to produce a heated liquid. While there are indeed many different embodiments for achieving such an operation, one preferred embodiment will be discussed herein.
  • Heating assembly 40 includes several components, among them a converter 42 (shown in more detail in Figures 5 and 6), a flush tank 60 (shown in more detail in Figure 7), a converter heater drain tank 62 (shown in more detail in Figure 8), a boiler blow down tank 64 (shown in more detail in Figure 9), a boiler or steam generator 66, a condensate storage tank 68 (shown in more detail in Figure 10) , and a feedwater heater 70 (shown in more detail in Figure 11) .
  • the following sets forth the operation of heating assembly 40, with reference to the flow diagram of Figure 4 and the more detailed depictions of certain components shown in Figures 5-11. It is noted that certain components of heating assembly 40 are not discussed in great detail.
  • converter 42 includes a housing 43 having a snow inlet 44, a debris screen 45, two primary heaters 46a and 46b each mounted to a different sidewall of housing 43 and separated by an opening 47, a baffle plate 48, two secondary heaters 50a and 50b each mounted to a different sidewall of housing 43 and separated by an opening 51, an agitator 52, and a steam sparger 54.
  • heaters 46a, 46b, 50a and 50b supply thermal energy to commence the melting of the snow in a snow-water bath.
  • the water resulting from the melting of snow in converter 42 is then pumped to a flush tank 60 (best shown in Figure 7), prior to ultimately being ejected from vehicle 10. This water may be removed through outlet 56 in converter 42, and introduced into flush tank 60 through inlet 61. Flow from converter 42 to tank 60 may be induced by gravity or by a pump
  • This water is heated in flush tank 60 through the transfer of heat from several sources.
  • flashing steam from a converter heater drain tank 62 (best shown in Figure 8) and a boiler blow down tank 64 (best shown in Figure 9) is added into flush tank 60 in order to heat the water therein.
  • bottom drains from boiler blow down tank 64 may also be pumped into flush tank 60, in order to add more heat.
  • supplemental heating may also be accomplished by directly circulating flush tank water through a boiler 66 and stack 67 gas heat recovery system (shown in Figure 4) and returning it to flush tank 60 through an eductor 69 and heater drains from feed water heater 70 (also shown in Figure 4 ) .
  • Boiler 66 is a component, as is well known in the art, for providing steam from a water source. Essentially, boiler 66 boils system water captured in a condensate storage tank 68. System water is water that substantially remains within the system and may at least be partially produced from captured snow. This water may remain in heating assembly 40 or may be changed with each use. A feed water heater 70 may be provided between tank 68 and boiler 66, for raising the temperature of the system water prior to entering boiler 66, such that the system water is up to an acceptable boiler inlet temperature. Steam produced from boiler 66 is utilized to heat heaters 46a, 46b, 50a and 50b.
  • the steam provided to the heaters moves into converter heater down tank 62, where a portion is utilized to further heat the water produced from captured snow in flush tank 60 and a portion is condensed to water and stored in condensate storage tank 68.
  • the steam provided from boiler blow down tank 64 is in turn provided to flush tank 60 to further heat the water produced from captured snow.
  • a certain amount of water is also taken from flush tank 60 to make-up for water lost, and provided to condensate storage tank 68 and ultimately boiler 66.
  • discharge portion 80 includes plurality of lances 82 fitted with high impact spray nozzles 84.
  • lance 82 for use in accordance with the present invention is shown in Figure 14, while one spray nozzle 84 for use in accordance with the present invention is shown in Figure 15.
  • water produced from captured snow is heated in flush tank 60 and thereafter provided to lances 82, as depicted in the flow diagram of Figure 4.
  • the heated water may pass through a flush tank side sprayer pump 86, an additional pipeline heater (s) 88, and a booster pump 90, prior to exiting each lance 82 at spray nozzle 84.
  • each lance 82 may include such components, or the components may aid in providing the heated water to multiple lances 82. Further, it is contemplated that certain components may not be required in certain embodiments. For example, depending upon the pressure of water in a given lance 82, a booster pump 90 may not be needed.
  • lances 82 are arranged such that they extend from both sides and the rear of vehicle 10. This allows for heated water to be sprayed in a substantially straight direction from nozzles 84.
  • the water being ejected from nozzles 84 of the plurality of lances 82 is heated such that it is useful in melting snow it comes into contact with.
  • the distance said water is projected may vary. Nevertheless, it is envisioned that snow, upon which the heated water lands, will be at least partially melted.
  • snow may be melted to the left and right of vehicle 10, thereby increasing the overall snow removal width of the system.
  • the apparatus of the figures may additionally melt snow in a distance y to the left and right of the vehicle, through the spraying of heated water from lances 82.
  • rear located lances 82 may be utilized to melt the remaining snow from the surface. In this operation, vehicle 10 would capture a portion of the height of the snow and then pass over the remaining height.
  • Rear mounted lances 82 may be directed such that water ejected therefrom comes into contact and melts the snow that was just passed over.
  • Vehicle 10 Water resulting from melted snow, as well as the water sprayed by vehicle 10 is likely to run off into standard drainage apparatus such as storm sewers or the like. Nevertheless, the operation of vehicle 10 typically occurs in generally cold temperatures. Thus, it is envisioned in certain embodiments to spray water from lances 82 with a certain amount of an environmentally safe non-toxic deicing chemical agent or deicing concentration, so as to prevent the freezing of the sprayed water and/or the melted snow.
