Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is further illustrated.
Embodiment 1
The discharge of the present embodiment crystallizer easily, as shown in Figure 1, 2, comprises crystallizing tank 1, and the bottom of described crystallizing tank 1 is provided with the discharge mouth of pipe 2, and the described discharge mouth of pipe 2 is equipped with ball valve 3 as blow-off valve; In the described discharge mouth of pipe 2, be provided with up big and down small tapered sleeve 9, the upper edge of this tapered sleeve 9 flushes with the inwall of crystallizing tank 1, the end face of the import mouth of pipe 11 of ball valve 3 is supported on lower edge, the inwall of the outer peripheral face of tapered sleeve 9 and the discharge mouth of pipe 2 fits tightly, lower to locating the inwall of inner peripheral surface a little more than the import mouth of pipe 11 of ball valve 1.The top of described crystallizing tank 1 and the discharge mouth of pipe 2 correspondence positions are provided with installs the mouth of pipe 4, the discharge mouth of pipe 2 coaxially arranges with the installation mouth of pipe 4, the described installation mouth of pipe 4 is equipped with stop valve 5, this stop valve 5 comprises valve body 6 and valve rod 7, described valve rod 7 stretches into crystallizing tank 1 from the mouth of pipe 4 is installed, one end that valve rod 7 stretches into crystallizing tank 1 is provided with the plug 8 of taper, valve rod 7 is through the inner chamber of crystallizing tank 1, make plug 8 enter the import mouth of pipe 11 of the discharge mouth of pipe 2 and ball valve 3, peg graft and coordinate with described tapered sleeve 9, and the small end face that makes plug 8 is supported the spherical valve core 10 of ball valve 3, the small end face of plug 8 is concave surface, adapt with the spherical valve core 10 of ball valve 3, the valve body 6 of described stop valve 5 can make valve rod 7 move up and down vertically.
When the crystallizer of the present embodiment uses, as shown in Figure 1, 2, first close ball valve 3, and making plug 8 on the valve rod 7 of stop valve 5 support the spherical valve core 10 of ball valve 3, mother liquor enters crystallizing tank 1 and carries out crystallization, after crystallization, crystal settling is in the bottom of crystallizing tank 1, because plug 8 tightly coordinates with tapered sleeve 9, the gap between the spherical valve core 10 of plug 8 and tapered sleeve 9, ball valve 3 is very little, almost there is no liquid in this crystallization; After crystallization, when discharge opeing, as shown in Figure 3,4, make valve rod 7 drive plug 8 to move up vertically by valve body 6, more than rising to solid liquid interface to the end of plug 8, open ball valve 3 and can discharge smoothly mother liquor; After discharge opeing finishes, then make valve rod 7 drive plug 8 to move down vertically by valve body 6, peg graft and coordinate with tapered sleeve 9 to plug 8, close ball valve, make the end of plug 8 support the spherical valve core 10 of ball valve 3, can carry out follow-up production work.
The discharge of the present embodiment crystallizer easily, for the crystallization process of lithium hexafluoro phosphate, the solid that crystallization produces can not stop up the discharge mouth of pipe and blow-off valve; When discharge, only valve rod need be risen and make more than its end rises to solid liquid interface, can form the passage to the discharge mouth of pipe and blow-off valve for mother liquor stream, facilitate the discharge of mother liquor; When discharge, do not need tipping arrangement and dismounting pipeline, simple to operation, improve greatly operating efficiency, saved manpower and materials; Meanwhile, when operation, can not cause the leakage of mother liquor, be particularly suitable for the production process that contains severe corrosive and toxicant in mother liquor, safe and reliable, be applicable to promoting the use of.
