Description

Technical Field

[0001] The utility model relates to an SPG membrane emulsifier with a limiter. Background Art

[0002] SPG membrane (porous glass membrane) is the core equipment of a microsphere preparation technology with low scale-up risk. The particle size of the spheres is related to the pore size of the membrane tube, the oil phase pressure, and the water phase flow rate.

[0003] Generally, the oil phase output of a 125mm long SPG membrane tube is about 10-20ml / min. Calculated based on the microsphere oil-water ratio of 1:100, the output of the original liquid is 1000-2000ml / min, or 60-120L / h.

[0004] The existing multi-tube SPG membrane emulsifier is installed in a straight-through manner. When installing, errors may occur, such as Figure 1 、 2 As shown, the membrane tube will eventually be displaced, and the displaced part of the membrane tube will form a direct oil phase channel, which cannot achieve the actual emulsification effect.

[0005] Therefore, in order to solve the above problems, a SPG membrane emulsifier with a limiter is proposed. Utility Model Content

[0006] The utility model aims to overcome the existing defects and provide an SPG membrane emulsifier with a limiter to prevent the membrane tube from being displaced after installation.

[0007] The technical solution for achieving the above object is: a SPG membrane emulsifier with a limiter, comprising a shell, wherein two countersunk holes are respectively provided at the upper and lower ends of the shell, and two membrane tubes are arranged in the shell, and the two ends of the membrane tubes are respectively located in the upper and lower countersunk holes;

[0008] The upper and lower ends of the shell are each connected to an interface part; two bosses are provided at one end of the interface part, and a step hole is provided in the boss, the boss is docked in the countersunk hole, and the step hole wraps the end of the membrane tube; a sealing ring is provided between the outer wall of the membrane tube and the inner wall of the countersunk hole.

[0009] Preferably, a first flange is connected to the shell, a second flange is connected to the interface component, and the first flange and the second flange are connected by knob bolts.

[0010] Preferably, the sealing ring is pressed by the boss.

[0011] Preferably, the outer wall of the shell is connected with an inlet pipe and an outlet pipe respectively.

[0012] Preferably, the sealing ring is made of polytetrafluoroethylene.

[0013] The beneficial effect of the utility model is that the SPG membrane emulsifier with limiter provides a stepped hole in the interface component so that both ends of the membrane tube are located in the stepped hole, thereby limiting the movement of the membrane tube and avoiding production problems caused by the membrane tube falling off.
