Description

Water-oil phase storage tank

Technical Field

The utility model relates to reverse osmosis membrane production equipment, in particular to a water-oil phase storage barrel.

Background Art

Reverse osmosis membranes usually include three layers: non-woven fabric, ultrafiltration base membrane and polyamide. Among them, polyamide as a functional layer directly determines the performance of the reverse osmosis membrane. In the production process of reverse osmosis membranes, polyamide is prepared by interfacial polymerization of aqueous amine monomers and oily acyl chloride monomers. Since production is a continuous process, the aqueous and oily phase monomers will be consumed all the time, so the aqueous and oily phases must be supplemented during the production process. The existing supplementation method usually uses a metering pump to add a high-concentration solution, but when the metering pump is in contact with oil and chemical reagents for a long time, it is easy to malfunction, resulting in inaccurate addition and affecting production.

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

The present invention is described below with reference to FIGS. 1-3 . In this case, a solution of a concentration required for the reaction is added into the main barrel 100 , and a solution of a high concentration is added into the supplementary barrel 200 .

Water-oil phase storage tank, including:

The main barrel 100 is provided with a material chamber;

The outside of the main barrel 100 is provided with a liquid inlet valve 110, a liquid return valve 120 and a replenishing pipe connection port 130 which are connected to the material chamber;

During operation, the liquid inlet valve 110 of the main barrel 100 is connected to the water-oil phase reaction tank, and the solution in the main barrel 100 is pumped into the water-oil phase reaction tank by a pump. An overflow port is provided in the water-oil phase reaction tank, and the solution exceeding the overflow port flows into the main barrel 100 through the liquid return valve 120.

After the reaction, the concentration of the solution in the main barrel 100 will decrease, and the supplementary barrel 200 is required to add high-concentration solution into the main barrel 100 to maintain the concentration of the main barrel 100. The tester takes samples for testing at regular intervals. If the concentration is high, the oil replenishment speed is reduced, and if it is low, the oil replenishment speed is increased.

The replenishment barrel 200 is provided with a replenishment chamber; a fixed replenishment reservoir 210 is provided near the top of the replenishment chamber, and the solution in the replenishment chamber is pumped into the replenishment reservoir 210 through the pneumatic diaphragm pump 220; a replenishment speed regulating valve 230 connected to the replenishment reservoir 210 is provided on the outside of the replenishment barrel 200, and the replenishment speed regulating valve 230 is connected to the replenishment pipe connection port 130 of the main barrel 100 through a hose. The replenishment pipe connection port 130 is provided above the return valve 120, and the flow generated by the return liquid helps the replenishment liquid to spread quickly and evenly.

In this case, the replenishment speed is mechanically adjusted by using the deadweight of the solution in the replenishment reservoir 210 and the replenishment speed regulating valve 230, so that the speed is more stable. Under the corrosion of organic solvents and chemicals, the electronic control device is prone to malfunction or unstable speed.

It is further defined that the pneumatic diaphragm pump 220 is fixedly disposed in the replenishing cavity, with the bottom extending into the bottom of the replenishing cavity through the first tube body, and the top extending into the replenishing liquid storage tank 210 through the second tube body.

The pneumatic diaphragm pump 220 receives air and pumps the solution in the replenishment barrel 200 into the replenishment reservoir 210. When the reservoir is full, the liquid will overflow from the top and flow back to the replenishment barrel 200. The pneumatic diaphragm pump 220 keeps working to maintain the replenishment reservoir 210 to be full of liquid.

It is further defined that an opening is provided at the top of the replenishment reservoir 210. The top of the replenishment reservoir 210 is open, and the solution will flow back into the replenishment barrel 200 when it is full. A replenishment speed regulating valve is provided at the bottom, and the solution outflow speed is changed by changing the opening and closing degree of the valve.

As a further optimization, a drain valve 240 connected to the replenishing chamber is provided on the outer side of the replenishing barrel 200 near the bottom for discharging waste liquid.

The structures of the main barrel 100 and the supplementary barrel 200 are further optimized

A circulating water inlet valve 141 and a circulating water outlet valve 142 extending out of the main barrel 100 are provided on the main circulating water layer 140.
