The invention discloses a
polyamide reverse osmosis compound membrane preparation device which structurally comprises a
membrane feeding outlet, a pressure bar, an upper box, a control box, a decorative screen, a preparation room, a
membrane feeding rack and an inner device. The
membrane feeding outlet is formed in the preparation room, the pressure bar penetrates the upper box, the preparation room is connected to the inner device, the control box and the decorative screen are adjacent, the control box is embedded onto the upper part, the decorative screen is glued to the side face of the upper box, the upper box is located above the preparation room, and the
two form an integrated structure. The preparation room is fixedly connected to the membrane feeding rack, and the
two form a T-shaped structure and is provided with a right angle. During preparation, agents in a first agent hopper are blanked separately by transmission for mixing and
processing. If a thickened supporting layer, the pressure bar is pressed, so that the agents in a second agent hopper are blanked through a first agent
pipe. The agents can be selected quantitatively. By adding the agents, the thickness of the supporting layer is increased, the
product diversity is selected, market choiceness is facilitated, and the market sales rate is improved.
