Static fluid mixing pump device

Abstract

A static fluid mixing pump device comprises a flow tube encasing a liner perforated with fluid jets for the introduction of a transport fluid at or in the vicinity of a transition section within the device.

1 . A static fluid mixing pump device including a narrow bore transport fluid inlet means, a fluid material tube having an inlet and an outlet for fluid material, the tube having a dimensionally increasing flared transition portion in a flow direction of the fluid material, and a plurality of fluid jets in the vicinity of said transition portion and connected to the transport fluid inlet means. 
   
   
       2 . A static fluid mixing pump device according to  claim 1  wherein the tube is a relatively outer hollow cylindrical tube having the inlet and the outlet for fluid material flow and the narrow bore transport fluid inlet means, the device including an inner generally hollow cylindrical liner for the tube sealably located coaxially therewithin, the liner having an inlet and an outlet registering with the inlet and the outlet of the tube respectively thus constituting a through passage from the inlet of the tube to the inlet of the liner and thence to the outlet of the liner and the outlet of the tube, a plenum chamber formed between the liner and the tube and communicating with the transport fluid inlet means, the liner having the flared portion defining the dimensionally increasing transition in the internal dimension of the liner in a direction from the inlet thereof towards the outlet thereof, and the plurality of fluid jets being defined in the wall of the liner and extending from the plenum to the inside of the liner. 
   
   
       3 . A static fluid mixing pump device according to  claim 2  wherein the liner is provided with a neck section upstream of the flared transition portion. 
   
   
       4 . A static fluid mixing pump device according to  claim 3  wherein the fluid jets are tangentially orientated at the same level in the liner downstream of the neck section. 
   
   
       5 . A static fluid mixing pump device according to  claim 3  wherein the fluid jets are tangentially orientated at different levels in the liner downstream of the neck section. 
   
   
       6 . A static fluid mixing pump device according to  claim 3  wherein the fluid jets are provided at at least one level and are radially orientated in the direction from the inlet to the outlet of the tube downstream of the neck section. 
   
   
       7 . A static fluid mixing pump device according to  claim 3  wherein the fluid jets are provided at at least one level and are angularly orientated in the direction from the inlet to the outlet of the tube downstream of the neck section. 
   
   
       8 . A static fluid mixing pump device according to  claim 1  wherein the fluid jets are nozzles. 
   
   
       9 . A static fluid mixing pump device according to  claim 1  wherein the fluid jets are formed of nozzles at the end of passages incorporating vanes of helical form. 
   
   
       10 . A static fluid mixing pump device according to  claim 2  wherein the liner is sealably held within the tube by O-rings, and circumferential grooves are provided in the outer periphery of the liner at each end thereof for the purpose in use of receiving said O-rings.
