However, as the scope of membrane applications continues to expand, the performance requirements for membranes in the membrane application process are also getting higher and higher. As one of the products in the membrane industry, reverse osmosis membranes have been widely used in seawater desalination, sewage treatment and other fields due to their own reverse osmosis performance and other properties.

[0003] Since the coating of the reverse osmosis membrane requires the coating materials to be mixed and prepared in appropriate proportions before use, the existing reverse osmosis membrane production coating feeding device can only be mixed by the operator based on experience, which can easily cause errors in the ratio and make the quality of each batch of reverse osmosis membranes different, thereby reducing the yield rate of the reverse osmosis membrane; the existing reverse osmosis membrane production coating feeding device can only pour the raw materials into the device in appropriate proportions in turn when in use, and the process is time-consuming, which reduces the feeding efficiency of the reverse osmosis membrane production coating feeding device.

[0004] Therefore, we propose a reverse osmosis membrane production coating feeding device to solve the above-mentioned problems. Utility Model Content

[0025] The movable plate 8 is provided with four through openings 801, and a second cover plate 802 is installed at the position of the through openings 801 of the movable plate 8. The second cover plate 802 is movably connected to the movable plate 8, and a second blocking block 803 is fixed to the movable position of the movable plate 8 with the second cover plate 802. The second blocking block 803 is at an angle of 45° with the movable plate 8 at the top of the side close to the second cover plate 802. A sealing ring 804 is arranged around the movable plate 8, and the sealing ring 804 allows the movable plate 8 to remain stationary inside the raw material barrel 7 without applying external force. When the movable plate 8 moves downward, the second cover plate 802 is pushed open by water pressure. When the second cover plate 802 is opened to 45°, the second cover plate 802 is blocked by the second blocking block 803, so that the second cover plate 802 can only be opened to 45°, so that the movable plate 8 can move in the raw material barrel 7 filled with raw materials.

[0026] Each end of the movable frame 5 is penetrated by a secondary threaded rod 9, and the movable frame 5 and the secondary threaded rod 9 are movably connected. The secondary threaded rod 9 is penetrated by a movable block 901 and a nut 902, and the secondary threaded rod 9 is threadedly connected to the movable block 901 and the nut 902. The movable frame 5 can move up and down with the secondary threaded rod 9, and the moving distance of the secondary threaded rod 9 can be controlled by adjusting the height of the movable block 901 and the nut 902 on the secondary threaded rod 9, so as to facilitate the control of the range of up and down movement of the movable plate 8 in the raw material barrel 7.

[0027] A fixed frame 6 is fixed between the raw material barrels 7, and the main threaded rod 401 passes through the fixed frame 6. The main threaded rod 401 and the fixed frame 6 are connected by bearings, and the main threaded rod 401 and the movable frame 5 are threadedly connected. The main threaded rod 401 can be driven to rotate by the second motor 4, so as to control the up and down movement of the movable frame 5.

[0028] The first cover plate 702 is movably connected to the bottom of the raw material barrel 7, and a first blocking block 703 is fixed to the bottom of the raw material barrel 7 at the movable position of the first cover plate 702, and the first blocking block 703 is set as an inclined surface with an angle of 45° between the top and the bottom of the raw material barrel 7 on the side close to the first cover plate 702. When the movable plate 8 moves upward, the first cover plate 702 can be pushed open to 45° by water pressure, and then the raw material enters the raw material barrel 7 from the raw material inlet 701, so that the raw material barrel 7 is always full of raw materials, which is convenient for continuously injecting raw materials into the device.

[0029] The raw material outlet 704 is connected to the mixing inlet 101 through a hose. The stirring rod 201 is arranged inside the main body 1 and can be driven by the first motor 2 to rotate inside the main body 1 to facilitate mixing of the raw materials entering the main body 1.

[0030] Working principle: When using the reverse osmosis membrane to produce coating feeding device, first connect the raw material inlet 701 of each raw material barrel 7 with different raw material holding pools through a hose, then adjust the height of the movable block 901 on each secondary threaded rod 9, and fix the movable block 901 through a nut 902, adjust the movable spacing of the movable frame 5 on the secondary threaded rod 9 to a suitable distance, so that the movable plate 8 can be lowered to a suitable height in the raw material barrel 7, so that a certain amount of raw materials can be taken out from the inside of each raw material barrel 7, and then turn on the second motor 4 to drive the main threaded rod 401 to rotate forward, so that the movable frame 5 moves downward, and the movable plate 8 moves downward in the raw material barrel 7. At the same time, the second cover plate 802 on the movable plate 8 is opened, and the second cover plate 802 is blocked by the second blocking block 803 after opening to 45°, so that the raw material at the lower part of the movable plate 8 moves to the upper part of the movable plate 8 through the through port 801. When the barrel 7 is at the top, the second motor 4 drives the main threaded rod 401 to reverse, so that the movable frame 5 moves upward, and at the same time drives the movable plate 8 to move upward. During the process, the second cover plate 802 is tightly attached to the movable plate 8 due to the force of water pressure, so that the raw material enters the main body 1 from the raw material outlet 704 through the mixing inlet 101. At the same time, the first cover plate 702 at the bottom of the raw material barrel 7 is opened and blocked by the first blocking block 703 to open to 45°. The raw material enters the raw material barrel 7 through the raw material inlet 701 to replenish the raw material in the raw material barrel 7. Then the first motor 2 is turned on to drive the stirring rod 201 to rotate, and the various raw materials entering the main body 1 are stirred and mixed. The mixed material is fed to the coating device through the mixing outlet 102, thus completing the use of the reverse osmosis membrane production coating feeding device, and the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
