Description
Technical field
The utility model is related to a kind of vacuum buffer tank for precipitated lithium liquid suction filtration, belong to lithium carbonate production equipment technology.
Background technology
Lithium carbonate is compound more important in current lithium salts, be mainly used in new energy car battery, glass ceramics,
Alloy and medicine and other fields, especially country advocates Green Travel, the principles and policies of low-carbon environment-friendly, New Energy Industry height in recent years
Speed development, just includes lithium ion battery among these, and the positive electrode cost in the lithium battery accounts for the 70~80% of entire battery, and
The main product of market today mainly includes the positive electrodes such as nickle cobalt lithium manganate, cobalt acid lithium, LiFePO4, can all use carbonic acid
Lithium is prepared, and as new-energy automobile needs are continuously increased, the problem is consequently increased, and especially power battery is asked
Inscribe especially prominent, this is just related to material purity and material property, therefore higher and higher to the purity requirement of lithium carbonate.
In the technique of industrial producing pure Lithium Carbonate, need lithium carbonate suspension to be filtered by vacuum and collects mother
Liquid.During vacuum filtration, the vacuum buffer tank being connected between suction filtration tank and vacuum pump plays stable negative pressure and to filtering
Gas carries out the effect of gas-liquid separation.Since vacuum buffer tank is directly connected with suction filtration tank, in this way during vacuumizing, than
It is easier to be extracted into vacuum buffer tank into lithium mother liquor in suction filtration tank.It although can be with into lithium mother liquor in into vacuum buffer tank
It is released and recycled by valve, but the volume of in general vacuum buffer tank is larger, and the sinker mother liquor entered in vacuum buffer is opposite
To be a small amount of, for significant portion in tank skin adhesion, the rate of recovery is low after entering in vacuum buffer tank into lithium mother liquor.Due to lithium carbonate product
Price is very high, and the irretrievable mother liquor in this part virtually reduces productivity effect.
Utility model content
The purpose of this utility model is to provide a kind of vacuum buffer tank for precipitated lithium liquid suction filtration, concrete scheme is：
A kind of vacuum buffer tank for precipitated lithium liquid suction filtration, including buffering tank body, buffering tank body is equipped with vacuum pump connector and suction filtration
Slot connector, is equipped with the inner tank body of upper opening in the surge tank body, the inner tank body be located at suction filtration tank connector just under
At side, gas-liquid separator is equipped at the upper opening of inner tank body；The bottom of inner tank body is connected with drain pipe, drain pipe and surge tank
The external of body connects, and drain pipe is equipped with tapping valve.
Further, the gas-liquid separator is a tubular cover, and the lower end of tubular cover and the upper end of inner tank body seal
Connection, the side of tubular cover are equipped with air inlet, and air inlet with suction filtration tank connector for connecting, and air inlet is along tubular cover
Tangential direction is distributed；The top of the tubular cover is equipped with gas outlet, and gas outlet is connected with buffering tank body, and gas outlet is located at tubular
At the center of cover, the lower part of gas outlet is equipped with annular block machine.
Further, the volume of the inner tank body is buffer tank volume 1/8~1/10.
Further, the inner tank body is connect by being detachably connected seat with buffering the madial wall of tank body.
The beneficial point of the utility model is：The vacuum buffer tank of this programme be equipped with inner tank body, inner tank body for store into
Enter the sinker mother liquor of vacuum buffer tank, inner tank body has smaller volume relative to vacuum buffer tank, can mitigate sinker mother liquor
In the adhesion of tank skin, the rate of recovery of this part sinker mother liquor is greatly improved, the benefit of lithium carbonate manufacturer can be increased.
