Method For Transportation Of Liquids By Steam Or Compressed Air And A Device For Realization Of The Method

Abstract

The present invention relates to a method and device for transportation of liquids by compressed gas or steam. According to the invention inside the vessel ( 1 ) at least two variable gas volumes V 1 , V 2 are formed. The level of the liquid in the two volumes changes and the switching of the processes of feeding and discharging is made by the created pressure difference between the gas volumes. Inside the device a second volume is formed by providing a cylinder ( 2 ) with opened bottom. A tube ( 10 ) with an inside valve ( 5 ) are installed in the cylinder ( 2 ). The movement of valves ( 3 ), ( 4 ), ( 5 ) is synchronized and depends on the position of the cylinder ( 2 ). The proposed method and device ensure smooth and trouble-free transportation of liquids.

1 . Method for transportation of liquids by compressed gas or steam including feeding a vessel connected to the atmosphere with liquid to a definite level, interruption of the connection to the atmosphere at reaching a preliminary defined level, blasting of compressed gas or steam inside the vessel and discharging the liquid, characterizing with that discharging performed by means of variable effective volume of the compressed gas respectively steam at which at least two variable volumes V 1  and V 2  inside the vessel are formed, influencing with different pressure p 1  and p 2  on at least two volumes of liquid and the level of the liquid in these volumes changes on stages.  
   
   
       2 . The method according to  claim 1 , characterizing with that switching the processes—feeding with liquid and filling the vessel, and discharging is performed by the created pressure difference p 2  and p 1  between the gas volumes V 2  and V 1 .  
   
   
       3 . The method according to  claim 1 , characterizing with that the upper limit of the pressure difference (p 1 −p 2 ) between the volumes V 1  and V 2  changes between 0.005 Bar and 0.1 Bar.  
   
   
       4 . A device for transportation of liquids by compressed gas or steam including a closed vessel with inlet and outlet for the liquid respectively with inlet check valve and outlet check valve, with inlet and outlet for the compressed gas or steam, respectively with inlet valve and outlet valve for the gas, characterizing with that: 
 a second volume inside the vessel  1  is formed by an opened in the bottom cylinder  2  which is installed in parallel with the vertical axes of the vessel  1 , free to move in vertical direction;    at the inlet for the compressed air a pipeline  11  with valve  12  is provided ending free inside the cylinder  2 , at which a pipe  10  with side orifices and inside valve  5  is mounted;    the valve  5  is connected by the lever  9  to the inlet valve  4  and outlet valve  3  at which the movement of valves  3 ,  4  and  5  is made synchronized depending on the variable volume of the compressed, gas or steam feeding the closed vessel  1  and the cylinder  2 .    
   
   
       5 . The device according to  claim 4 , characterizing with that the flap of the inside valve  5  is enlarged and firmly connected to the flap of the outlet valve  3  at which on the enlargement of the flap of valve  5  a channel is formed to connect the end of lever  9 , connected to the side wall of the vessel  1  with limited by end stop rotational movement and at which lever  9  the thrust of the flap of valve  4  is sliding.  
   
   
       6 . The device according to any  claim 3  or  4 , characterizing with that in parallel with the axis of the vessel  1  a tube  15  is mounted free connected to the support  16  on the bottom of the vessel, at which the tube  10  of the cylinder  2  is connected firmly to tube  15 .  
   
   
       7 . The device according to any  claim 3 ,  4  or  5  characterizing with that to the inlet of the compressed gas or steam a pipeline  13  is installed ending inside the cylinder  2  near its upper end, at which to the free end of the pipeline  13  inside the cylinder  2  a float valve for limiting of the maximum level of the liquid inside the cylinder is provided.
