Detailed Description
The invention is described in further detail below with reference to the figures and the embodiments.
As shown in fig. 1-2, a sodium hypophosphite evaporation concentration device, including concentrated jar 1, concentrated jar 1 lateral wall is equipped with steam heating jacket 2, the vertical (mixing) shaft 3 that is equipped with in the concentrated jar 1, the (mixing) shaft 3 top is connected with driving motor 4 output, the (mixing) shaft 3 surface is equipped with stirring vane 5, the (mixing) shaft 3 upside and downside all with the 6 one end fixed connection of connecting rod of horizontal setting, the connecting rod 6 other end and the 7 tip swivelling joints of rotation axis of vertical setting, rotation axis 7 surface is around being equipped with helical blade 8, helical blade 8 one side is close to concentrated jar 1 inside wall, concentrated jar 1 inside wall still is equipped with ring gear 9, ring gear 9 inboard and straight-teeth gear 10 meshing, straight-teeth gear 10 is fixed in on the rotation axis 7.
Preferably, two groups of connecting rods 6 are arranged on the upper side and the lower side of the stirring shaft 3 by taking the stirring shaft 3 as a symmetrical center. Through the structure that sets up like this symmetry, the counter weight is balanced, can be so that its rotation process is more stable.
Preferably, the end of the connecting rod 6 is rotatably connected with the end of the vertically arranged rotating shaft 7 through a limit bearing 11.
Preferably, a feed inlet 1.2 is arranged on a top cover 1.1 of the concentration tank 1, one side of the steam heating jacket 2 is provided with an air inlet 2.1, and the other side is provided with a condensed water outlet 2.2.
