Definitions

  • the present invention relates to an evaporation apparatus for solvent fuel, and more particularly, to an evaporation apparatus having a fuel container in which the fuel being maintained at a predetermined height so as to keep the fuel density at a constant value thereby reducing the heat loss and supplying the fuel rapidly for combustion.
  • an ordinary fuel tank 1 in which storing a solvent fuel 11 is provided with a heating plate at the bottom of the tank 1 thereof for heating the solvent fuel 11.
  • the temperature in the tank 1 is controlled at a constant value within the range of evaporation temperature of the solvent fuel 11.
  • the air is conducted into the tank 1 from its top end by means of a blower 12 so as to evaporate the solvent fuel 11.
  • the gaseous fuel is conducted into a gas burner or a boiler via an output pipe for combustion. It is found out that the aforesaid conventional way of transforming the liquidal fuel into gaseous fuel for combustion has following shortcomings:
  • the object of the present invention is to provide an evaporation apparatus for solvent fuel with an extra fuel reservoir installed outside of the evaporation tank, and a fuel level controller for controlling the amount of fuel in the evaporation tank is equipped therein so as to maintain the concentration of gaseous fuel in the evaporation tank in a preferable state for stable combustion.
  • the fuel level controller of the evaporation apparatus for solvent fuel is composed of a float bowl and a gate switch, the on/off of the latter is controlled by the position of the former which in turn controls the amount of fuel contained in the evaporation tank.
  • a heating strip is installed outside of the lower end of the evaporation tank, the heating strip is connected with a temperature controller having an inner rod shaped temperature gage to control the inner temperature of the evaporation tank stably at a constant value.
  • the present invention has only to heat a small amount of fuel in a short heating time so that the temperature can be easily controlled and the quality of the fuel is upgraded by maintaining the concentration of gaseous fuel stably.
  • the evaporation apparatus of the present invention comprises an evaporation tank 2, a fuel reservoir 3, and a liquid fuel level controller 4.
  • a blower motor 21, a pressure switch 22, and a gaseous fuel exit 23 are installed on the top surface of the evaporation tank 2.
  • One end of the blower motor 21 is connected to an air inlet pipe 24 to introduce the air into the apparatus and the back flow of the air and the gaseous fuel is prevented by a check valve 25.
  • the air inlet pipe 24 introduces the air into the evaporation tank 2 from its bottom so as to promote evaporation of the fuel.
  • the pressure switch 22 is for detecting pressure in the tank 2 and jointed to the blower motor 21 for controlling the operation of the motor 21.
  • the gaseous fuel in the tank 2 is conducted out of the tank 2 via the fuel exit 23.
  • a rod shaped temperature gage 26 provided at the bottom of the evaporation tank 2 is connected to a temperature controller 27.
  • the temperature controller 27 is further connected to a heating strip 28 provided along outer edge of the bottom portion of the tank 2.
  • a graduation 29 is provided on part of the outer surface of the tank 2 for indicating the variation about amount of fuel inside the tank 2 so as to judge if the liquidal fuel level controller 4 operates normally.
  • a fuel relief port 291 is provided at the bottom of the tank 2 to release the fuel when the tank 2 is to be cleaned.
  • An air conducting pipe 31 is interconnected between the upper portion of the evaporation tank 2 and the fuel reservoir 3 so as to maintain an equal air pressure for the two containers 2 and 3.
  • a graduation 32 is also provided on part of the outer surface of the fuel reservoir 3 for indicating amount of fuel remaining in the reservoir 3 for replenishing the solvent fuel from a fuel supply port 33 in case of need.
  • a fuel relief port 34 is provided at the bottom of the reservoir 3 to release the fuel when the reservoir 3 is to be cleaned.
  • the liquidal fuel level controller 4 equipped in the evaporation tank 2 consists of a float bowl 41 and a gate switch 42, the former detects the fuel level and actuates the latter.
  • a fuel supply pipe 43 is interconnected between the lower portions of the fuel reservoir 3 and the evaporation tank 2. The end of the fuel supply pipe 43 is connected to the gate switch 42 so as to control amount of fuel supplied to the tank 2.
  • the gate switch 42 is actuated to force the liquidal fuel in the reservoir 3 to flow into the tank 2 via the fuel supply pipe 43, until the liquidal fuel level controller 4 detects that the fuel level in the tank 2 has reached the predetermined height and closes the gate switch 42 to stop fuel supply.
  • the fuel in the tank 2 maintains at a fixed height by the liquidal fuel level controller 4 thereby shortening the heating time and maintaining concentration of the gaseous fuel in the evaporation tank 2 stably at a constant value.
  • the variation of quantity of fuel is also regulated in a fixed range.
  • the heating of fuel can only be earned out with respect to this range thereby the concentration of the fuel in the tank 2 is easily controlled.
  • the fuel contained in the tank 2 can always be held at a constant level to perform a stable evaporation effect to achieve a stable combustion efficiency.
  • the gaseous fuel produced by the apparatus of the present invention be supplied to a gas burner 61 and a boiler 62 shown in Fig. 3, the combustion efficiency would be largely improved with a prolonged lifetime.
  • the graduations 29 and 32 respectively provided with the tank 2 and reservoir 3 indicate the respective fuel level thereof and they are observable by naked eye so as to replenish new fuel from time to time.
  • the liquidal fuel level controller 73 is not equipped in the evaporation tank 2, but instead of it, installed in a fuel supplier 7 interposed between the evaporation tank 2 and the fuel reservoir 3 and is connected to the former with a pipe 74 and to the latter with a pipe 75 respectively, and an extension pipe 76 is uprightly erected to communicate with the pipe 31 for balancing the internal pressure of the tank 2 and the reservoir 3.
  • the liquidal fuel level controller 73 is composed of a float bowl 71, and a gate switch 72.
  • the evaporation apparatus for solvent fuel of the present invention successfully utilizes the liquidal fuel level controller in the evaporation tank to control fuel level in a predetermined range so as to maintain concentration of the gaseous fuel stably and improve the combustion efficiency.
