Evaporation apparatus for solvent fuel

Abstract

An evaporation apparatus for solvent fuel has an extra fuel reservoir installed outside of an evaporation tank, and a fuel level controller for controlling the amount of fuel in the evaporation tank so as to maintain the concentration of gaseous fuel in the evaporation tank in a preferable state for stable combustion. The fuel level controller 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 installed outside of the evaporation tank is connected with a temperature controller having a temperature gage to control the inner temperature of the evaporation tank stably at a constant value. This apparatus 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 keeping the concentration of gaseous fuel stably.

1 . An evaporation apparatus for solvent fuel comprising an evaporation tank, a fuel reservoir, and a liquidal fuel level controller; wherein a blower motor, a pressure switch, and a gaseous fuel exit are installed on the top surface of said evaporation tank, one end of said blower motor is connected to an air inlet pipe to introduce the air into said apparatus, a check valve is installed at the joint portion of said blower, motor outlet and said air inlet pipe for preventing back flow of the air and the gaseous fuel; 
 said apparatus is characterized in that the air is introduced into said evaporation tank from said fuel reservoir via said air inlet pipe, said liquidal fuel level controller equipped in the lower portion of said evaporation tank is composed of a float bowl and a gate switch, said float bowl detects the fuel level and actuates said gate switch for regulating amount of fuel supply, thereby maintaining the fuel level in said evaporation tank at a predetermined height and achieving stable evaporation effect, the variation of fuel level never affects the evaporation effect or combustion efficiency.    
     
     
         2 . The evaporation apparatus as in  claim 1 , wherein a rod shaped temperature gage is provided at the bottom portion of said evaporation tank, and said temperature gage is connected to a temperature controller, a heating strip provided along outer edge of the bottom portion of said evaporation tank is connected to said temperature controller which detects the inner temperature of said evaporation tank and actuates said heating strip if said temperature is lower than the predetermined value.  
     
     
         3 . The evaporation apparatus as in  claim 1 , wherein said check valve installed at the joint portion of said blower motor outlet and said air inlet pipe is for preventing back flow of the air and the gaseous fuel.  
     
     
         4 . The evaporation apparatus as in  claim 1 , wherein said fuel level controller is installed in a fuel supplier interposed between said evaporation tank and said fuel reservoir for controlling fuel input to said evaporation tank.  
     
     
         5 . The evaporation apparatus as in  claim 4 , wherein said fuel supplier communicates its two ends respectively to said evaporation tank and said fuel reservoir with a pipe, and an extension pipe is uprightly erected to communicate with an air conducting pipe interconnecting said evaporation tank and said fuel reservoir so as to balance the internal pressure of both tank and reservoir.
