Definitions

  • the presently disclosed subject matter relates to rotor - type liquid metal pump for realization of chemical reactor heating circuit, for example for realization of continuous heat transport process within the process of plastic waste material depolymerisation for component recovery.
  • Liquid metal mechanical pumps described in another patent specifications are designed as submersible and are used for periodical operation consisting of transferring of liquid metal between tanks or to moulds, as for example in invention specifications US2010196151 , CN101363691 , KR20090126368 , CA2538556 , MXPA05004332 , US2001000465 , W02004040143 , utility pattern specifications CN201666260 , CN202157970 , CN201335021 , CN2890429 or patent specifications US6439860 , US6345964 , JP4874243 .
  • Body of the pump for chemical reactor heating system has inflow chambers from both sides of the rotor ensuring heating medium circulation.
  • Liquid metal is fed to inflow chambers by means of at least two-way collector.
  • Collector sections are chosen to maintain quantitative balance of liquid metal fed into both inflow chambers.
  • Each collector arm is introduced into an inflow chamber in favourably tangent way, causing whirl of metal stream according to rotor sense of rotation.
  • Pump body is provided with favourably top and bottom inflow chambers for liquid metal.
  • One of those inflow chambers is provided with flange for fitting of pump shaft protective sheath of length greater than level of liquid metal in the tank, from which it is flowing into the pump and in this sheath a protective atmosphere is maintained between instantaneous level of liquid metal and the seal of rotor drive shaft.
  • Pump according to the present invention is characterized by a much lower failure frequency comparing to pumps used previously for liquid metal in the metallurgical industry. Balanced feeding of the pump significantly extends the lifetime of bearing shells, and also lifetime of the pump operated in chemical reactor heating system.
  • Example of embodiment of the present subject matter is depicted in Figures 1 to 3 , where vertical section of the pump is depicted in Fig. 1 , section of the pump in the rotor plane is depicted in Fig. 2 and top view in horizontal section is depicted in Fig. 3 .
  • the pump is provided with connecting pipe 1 passing into two-way collector 2 for liquid metal inflow from the kettle, two inflow chambers, located over 3 and under 3a pump body, feeding liquid metal from both sides of the rotor 9 .
  • Each of both parts of inflow collector 2 is connected to generatrix of chambers 3 and 3a in favourably tangent direction, in the way causing whirl of metal stream according to rotor sense of rotation.
  • liquid metal is introduced in a way bypassing rotor axle.
  • inflow openings 11 are provided, through which liquid metal can inflow in axial direction from both sides, along pump shaft 6 , among rotor blades.
  • Material of cover 4 and pump body 8 existing between openings 11 holds in a position bearing shell seats 7 of rotor shaft.
  • Material of bearing shells does not contain copper because of most of metals used for heat transport wash out copper from bearing shells causing their erosion and fast wear.
  • Outflow pipe 10 of pumped metal is led tangentially to the body of rotor chamber.
  • Protective sheath 12 of rotor shaft is fitted to the flange 5 . Height of protective sheath 12 is greater than level of liquid metal in the kettle, from which it is flowing into the pump. Protective atmosphere is maintained between metal level in this sheath and shaft seal.
