Mutually combination.Describe the utility model in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
Reference picture 1, preferred embodiment of the present utility model provide a kind of cobalt carbonate reaction unit suitable for successive reaction,
It includes being used for the reactor 1 for holding reaction solution, and the top of reactor 1, which is provided with, to be used to convey in reaction solution to reactor 1
Feeding mechanism, the interior agitating paddle 2 being provided with for stirring reaction solution of reactor 1, the bottom of reactor 1 is provided with discharge gate 3, reactor
1 side is provided with subsider 4.The top of subsider 4 offers the leakage fluid dram 5 for discharging reaction mother liquor, subsider 4 and reactor 1
Connected by connecting tube 6, and exchanging for material between subsider 4 and reactor 1 is realized by connecting tube 6.
Reactor 1 is made of PPH or stainless steel, and its shape is cylindrical in shape, and volume is 5~10 cubic metres.Specifically, react
Kettle 1 includes surrounding columned side wall 10, is connected to the lower section of side wall 10 and substantially recessed circular arc bottom wall 12, reactor 1
Top opens.The bottom of side wall 10 of reactor 1 has opening 11.And discharge gate 3 is then opened in the center of bottom wall 12 of reactor 1,
For the discharge inside reactor 1 and empty.
Alternatively, the inner surface of the side wall 10 of reactor 1 is evenly distributed with four pieces of side blocks being used for reaction solution flow-disturbing
Plate 8, the length of each piece of side shield 8 are the 2/3~3/4 of the height of reactor 1, and four pieces of side shields 8 are between each other in side wall 10
Inner surface is in 90 degree of distributions.Alternatively, the inner surface of the bottom wall 12 of reactor 1 is uniformly laid with three pieces and is used to disturb reaction solution
The low head baffle plate 7 of stream, the length of low head baffle plate 7 are the 1/3~1/2 of the diameter of reactor 1, and three pieces of low head baffle plates 7 are mutual
Between bottom wall 12 inner surface in 120 degree be distributed.The quantity and size design of side shield 8 and low head baffle plate 7 can realize compared with
Good flow-disturbing function, avoid excessive causing excessive to resistance caused by solution or causing to reach because baffle plate is too small because baffle plate is excessive
Less than the phenomenon of flow-disturbing effect.Equally distributed side shield 8 and low head baffle plate 7 can to reaction solution flow-disturbing in reactor 1,
So that stirring is evenly, strengthen the mixing effect of the internal-response solution of reactor 1, precipitate the cobalt carbonate of generation and more level off to
It is spherical, improve the uniformity of product.
Subsider 4 is also substantially cylindrical in shape, and its volume is the 10%~30% of the volume of reactor 1, to ensure in subsider 4
