Technical Field

[0001] The utility model relates to the technical field of reverse osmosis membranes for industrial sewage treatment, in particular to a reverse osmosis membrane component for industrial sewage treatment. Background Art

[0002] In industrial wastewater treatment, reverse osmosis membrane technology is highly favored due to its high efficiency and environmental friendliness. Reverse osmosis membrane is a highly efficient separation membrane that can selectively separate feed and liquid based on pressure difference1. When treating industrial wastewater, it can effectively filter out impurities such as colloids, microorganisms, dissolved salts, etc. in the wastewater, playing an important role in the resource utilization of industrial wastewater.

[0003] At present, most sewage is filtered through reverse osmosis membranes, but the efficiency is too low, which affects the purification effect. The reverse osmosis membranes need to be replaced in time. However, when replacing them, the external parts need to be disassembled one by one, which is cumbersome and increases the replacement time.

[0004] Therefore, we propose a reverse osmosis membrane component for industrial wastewater treatment in order to solve the problems raised above. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-5 The utility model provides a technical solution: a reverse osmosis membrane assembly for industrial sewage treatment, comprising a pipe body 1 and a water tank 2, an upper connecting block 4 is provided above the pipe body 1, and a lower connecting block 6 is connected to the bottom of the pipe body 1, the top of the upper connecting block 4 is connected to a top cover 3, and a reverse osmosis membrane 14 is installed at the bottom of the upper connecting block 4, and a water inlet pipe 5 is installed on the left side of the top of the top cover 3, the top of the lower connecting block 6 is connected to a limiting block 15, the bottom of the lower connecting block 6 is connected to the water tank 2, and a partition 7 is provided in the center of the water tank 2, and a water outlet 13 is provided at the lower right side of the water tank 2, a water pump 8 is provided inside the partition 7, and a guide tube 9 is installed at the bottom of the water pump 8, a connecting pipe 16 is connected to the top of the water pump 8, and a tee pipe 11 is installed at the end of the connecting pipe 16, a water outlet pipe 10 is installed at the front and rear ends of the tee pipe 11, and the end of the water outlet pipe 10 is connected to the right side of the top cover 3, and a connecting piece 12 is installed at the front and rear ends of the top cover 3.

[0022] The partition 7 divides the water tank 2 into two parts, left and right. The reverse osmosis membrane 14 inside the tube body 1 on the left side of the partition 7 is large-diameter, and the reverse osmosis membrane 14 inside the tube body 1 on the right side of the partition 7 is small-diameter. The sewage is basically filtered through the large-diameter reverse osmosis membrane 14, and then the water is sent to the small-diameter reverse osmosis membrane 14 for secondary filtration through the water pump 8, so that the treatment quality of the sewage is improved to a certain extent.

[0023] The limit block 15 is at the same height as the bottom seal of the reverse osmosis membrane 14. After the sewage is treated by the reverse osmosis membrane 14, it will flow out through the surface of the reverse osmosis membrane 14. The same height of the limit block 15 as the seal of the reverse osmosis membrane 14 can avoid the situation where the treated sewage is prevented from flowing out of the pipe body 1 by the limit block 15, thereby reducing the retention of sewage in the pipe body 1.

[0024] Four upper connecting blocks 4 are connected to the bottom of the top cover 3, and the upper connecting blocks 4 are respectively installed at positions corresponding to the center of the lower connecting block 6. The bottom of the upper connecting block 4 is connected to the reverse osmosis membrane 14. When the reverse osmosis membrane 14 needs to be replaced, it is only necessary to pull up the top cover 3 through the connecting piece 12, and the reverse osmosis membrane 14 connected to the bottom of the upper connecting block 4 will be pulled out of the tube body 1 together, so that the reverse osmosis membrane 14 is outside the tube body 1, thereby reducing the replacement time.

[0025] Through holes are provided on both sides of the connection between the tube body 1 and the lower connecting block 6. The water filtered by the reverse osmosis membrane 14 will be retained in the inner cavity of the tube body 1. The water will then flow into the water tank 2 through the through holes, so that it can quickly flow out of the inside of the tube body 1, avoiding impurities from adhering to the tube body 1 and extending the service life of the tube body 1.

[0026] Working principle: When using the reverse osmosis membrane assembly for industrial wastewater treatment, first, the sewage enters the reverse osmosis membrane 14 installed at the bottom of the upper connecting block 4 through the water inlet pipe 5. Since the partition 7 divides the water tank 2 into two parts, and the reverse osmosis membrane 14 inside the tube body 1 on the left side of the partition 7 is large-diameter, the sewage is basically filtered by the large-diameter reverse osmosis membrane 14, and then the water is sent to the water tank 2 through the opening opened at the connection between the tube body 1 and the lower connecting block 6. The limit block 15 is at the same height as the sealing part at the bottom of the reverse osmosis membrane 14. After the sewage is treated by the reverse osmosis membrane 14, it will flow out, avoiding the situation where the treated sewage cannot flow out of the tube body 1, thereby reducing the retention of sewage in the tube body 1;

[0027] Secondly, the sewage after basic treatment is introduced from the water tank 2 into the partition pipe 9 by the rotation of the water pump 8 inside the partition 7. The basically treated sewage is then sent to the connecting pipe 16 by the water pump 8, and then distributed to the outlet pipe 10 through the tee pipe 11 at the end of the connecting pipe 16, and flows into the small-diameter reverse osmosis membrane 14 for secondary filtration, thereby improving the treatment quality of the sewage.

[0028] After that, the water that has undergone secondary filtration flows into the water tank 2 through the through hole, and then flows to the next process through the water outlet 13 at the bottom right side of the water tank 2;

[0029] Finally, the bottom of the four upper connecting blocks 4 connected to the bottom of the top cover 3 is connected to the reverse osmosis membrane 14. After the filtration is completed, when the internal reverse osmosis membrane 14 needs to be replaced, it is only necessary to pull up the top cover 3 through the connecting piece 12, and the reverse osmosis membrane 14 connected to the bottom of the upper connecting block 4 will be pulled out of the tube body 1 together, so that the reverse osmosis membrane 14 is outside the tube body 1, thereby reducing the replacement time. After the filtration is completed, the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.

[0030] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
