Description

Technical Field

[0001] The utility model relates to the technical field of reverse osmosis equipment, and more specifically, to a disc-tube type reverse osmosis equipment. Background Art

[0002] The reverse osmosis equipment passes the raw water through a sand filter tank for sedimentation, and then passes it through a fine filter, a granular activated carbon filter, a compressed activated carbon filter, etc. It is pressurized by a primary plunger high-pressure pump and a secondary plunger high-pressure pump, and then transported to the DTRO membrane assembly. The DTRO membrane has a pore size of 1 / 10000μm (equivalent to 1 / 6000 of the size of E. coli and 1 / 300 of a virus) and uses a reverse osmosis membrane (RO membrane) to convert higher-concentration water into low-concentration water. At the same time, all impurities such as industrial pollutants, heavy metals, bacteria, viruses, etc. that are mixed into the water are completely isolated, thereby achieving the physical and chemical indicators and hygiene standards specified for drinking water, and producing the clearest and purest water, which is the best choice for the human body to replenish high-quality water in a timely manner.

[0003] Disc tube reverse osmosis is a membrane column composed of disc type membrane, guide plate, O-type rubber gasket, central tie rod and pressure-resistant casing.

[0004] At present, the permeable membrane of the disc-tube membrane assembly is prone to scaling and its service life is shortened, so it needs to be replaced in time. The existing membrane assembly is inserted into the equipment frame through the screw on the tube, a nut is put on the screw, and then the nut is tightened with a wrench to fix the membrane assembly. However, the above installation process is relatively cumbersome and it is not convenient for the staff to quickly disassemble or install. Utility Model Content

In addition, the same reference symbol is used for the same structure, element or accessory appearing in more than two figures to reflect similar features.

[0022] The utility model embodiment discloses a disc tube type reverse osmosis equipment. Figure 1-4 A disc-tube reverse osmosis device comprises an equipment frame 1 and a plurality of disc-tube membrane columns 2 located on the equipment frame 1. A mounting hole is opened inside the equipment frame 1, a fixing rod 9 is inserted inside the mounting hole, one end of the fixing rod 9 is arranged on the disc-tube membrane column 2, a limit block 10 is arranged on the surface of the fixing rod 9, the limit block is in an L shape, and the vertical and horizontal plates of the limit block 10 are inserted into the equipment frame 1, both sides of the inside of the fixing rod 9 are slidably connected with a limit plate 15, one end of the limit plate 15 extending to the outside of the fixing rod 9 is wedge-shaped, a spring 14 is arranged on the inner side of the limit plate 15, and a pull rope 13 is arranged on the inner side of the limit plate 15;

A locking mechanism is provided at one end of the pull rope 13, and the locking mechanism includes a threaded hole 16 opened in the fixing rod 9, the inner thread of the threaded hole 16 is connected with a screw rod 12, and a manual rotating rod 11 is provided at the top of the screw rod 12, and the surface of the manual rotating rod 11 is movably connected with the fixing rod 9;

[0024] Specifically, the fixing rod 9 on the disc-tube membrane column 2 is inserted into the equipment frame 1. During the insertion process, the fixing rod 9 drives the limit plate 15 to contact the mounting hole in the equipment frame 1, and pushes the limit plate 15 to slide into the fixing rod 9. After the limit plate 15 passes through the mounting hole, it slides out of the fixing rod 9 and contacts the surface of the equipment frame 1. At the same time, the vertical and horizontal plates of the limit block 10 are inserted into the equipment frame 1 to complete the installation of the disc-tube membrane assembly. The manual rotating rod 11 is manually rotated to drive the screw rod 12 to rotate. The screw rod 12 rotates and moves upward through the threaded hole 16, and at the same time, the pull rope 13 is wound and moved. The pull rope 13 moves and pulls the limit plate 15 to slide into the fixing rod 9. Then the disc-tube membrane column 2 is moved to drive the fixing rod 9 out of the mounting hole to complete the disassembly of the disc-tube membrane assembly.

[0025] Through the above structural design, the purpose of facilitating the staff to quickly disassemble or install the disc-tube membrane module is achieved;

[0026] Reference Figure 2The disc-tube membrane column 2 includes a pressure vessel, a central tie rod 8, a DTRO diaphragm 6, a guide plate 5, a rubber gasket 71, and a permeate flow pipe 7. A water inlet 3 and a liquid discharge port 4 are provided on the top of the pressure vessel. The DTRO diaphragm 6 is provided between two guide plates 5. The distance between each two adjacent guide plates 5 is 5 mm. The rubber gasket 71 is placed in grooves on both sides of the guide plates 5. The central tie rod 8 passes through the center of the DTRO diaphragm 6, the guide plate 5 and the rubber gasket 71. The permeate flow pipe 7 is located between the guide plate 5 and the central tie rod 8. A flow pipe is provided inside the fixed rod 9, and the flow pipe is communicated with the rubber gasket 71. A flow pipe is provided inside the fixed rod 9, and the flow pipe is communicated with the rubber gasket 71.

[0027] Specifically, sewage enters the pressure vessel through the water inlet 3, flows from the channel between the guide plate 5 and the shell to the other end of the component, and the sewage at the other end enters the guide plate through the channel. The treated sewage flows quickly through the DTRO membrane 6 at the shortest distance, then reverses 180° to the other membrane surface, and then flows into the next guide plate from the slot in the center of the guide plate, thereby forming a flow on the membrane surface from the circumference of the guide plate to the center of the circle, and then to the circumference. The concentrated sewage is finally discharged from the drain port 4. At the same time, the DTRO membrane 6 discharges the permeate separated from the sewage through the permeate flow pipe 7 and the flow pipe.
