One end that described valve rod stretches into crystallizing tank is provided with the plug of taper, and the small end face of described plug supports the spherical valve core of ball valve.
Be provided with up big and down small tapered sleeve in the described discharge mouth of pipe, described tapered sleeve coordinates with valve rod or plug grafting.
The upper edge of described tapered sleeve flushes with the inwall of crystallizing tank, and ball valve import mouth of pipe end face is supported on lower edge.
The outer peripheral face of described tapered sleeve and the inwall of the discharge mouth of pipe fit tightly, and to flush with ball valve import internal wall of pipe orifice or a little more than ball valve import internal wall of pipe orifice along place's inner peripheral surface down.
Discharge of the present invention crystallizer easily, stop valve after repacking is housed above crystallizing tank, the valve rod of stop valve supports the spherical valve core of below ball valve through the inner chamber of crystallizing tank to the discharge mouth of pipe, makes the crystalline solid produced in crystallization process can not block the discharge mouth of pipe and blow-off valve; During discharge, only valve rod need be risen and make its end rise to more than solid liquid interface, can be formed for the passage of mother liquor stream to the discharge mouth of pipe and blow-off valve, facilitate the discharge of mother liquor; Equipment of the present invention, does not need tipping arrangement and dismounting pipeline during discharge, simple to operation, greatly improves operating efficiency, saves manpower and materials; Meanwhile, during operation, the leakage of mother liquor can not be caused, be particularly suitable for the production process containing severe corrosive and toxicant in mother liquor, as the crystallization process etc. of lithium hexafluoro phosphate, safe and reliable, be applicable to promoting the use of.

Detailed description of the invention
Below in conjunction with detailed description of the invention, the present invention is further illustrated.
Embodiment 1
The discharge crystallizer easily of the present embodiment, 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; Up big and down small tapered sleeve 9 is provided with in the described discharge mouth of pipe 2, 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 outer peripheral face of tapered sleeve 9 and the inwall of the discharge mouth of pipe 2 fit 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 position are provided with installs the mouth of pipe 4, the discharge mouth of pipe 2 is coaxially arranged 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 installation mouth of pipe 4, 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, plug 8 is made to enter the import mouth of pipe 11 of the discharge mouth of pipe 2 and ball valve 3, coordinate with the grafting of described tapered sleeve 9, and make the small end face of plug 8 support 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 the 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, does not almost have liquid in this crystallization; After crystallization during discharge opeing, as shown in Figure 3,4, make valve rod 7 drive plug 8 to move up vertically by valve body 6, the end to plug 8 rises to more than solid liquid interface, opens ball valve 3 and gets final product smooth discharge mother liquor; After discharge opeing terminates, then make valve rod 7 drive plug 8 to move down vertically by valve body 6, coordinate with tapered sleeve 9 grafting to plug 8, close ball valve, make the end of plug 8 support the spherical valve core 10 of ball valve 3, can follow-up production work be carried out.
The discharge crystallizer easily of the present embodiment, for the crystallization process of lithium hexafluoro phosphate, the solid that crystallization produces can not block the discharge mouth of pipe and blow-off valve; During discharge, only valve rod need be risen and make its end rise to more than solid liquid interface, can be formed for the passage of mother liquor stream to the discharge mouth of pipe and blow-off valve, facilitate the discharge of mother liquor; Tipping arrangement and dismounting pipeline is not needed during discharge, simple to operation, greatly improve operating efficiency, save manpower and materials; Meanwhile, during operation, the leakage of mother liquor can not be caused, be particularly suitable for the production process containing severe corrosive and toxicant in mother liquor, safe and reliable, be applicable to promoting the use of.
In other embodiments of the invention, can also plug be saved, the end of valve rod is directly inserted in tapered sleeve and supports the spherical valve core of ball valve; Or save tapered sleeve, in the discharge mouth of pipe making plug directly insert crystallizing tank, support the spherical valve core of ball valve; Or save plug and tapered sleeve simultaneously, in the discharge mouth of pipe making the end of valve rod directly insert crystallizing tank, support the spherical valve core of ball valve.
