Description

Technical Field

[0001] The utility model relates to the technical field of replacing RO filter membranes, in particular to a steel frame for replacing RO filter membranes in a narrow space. Background Art

[0002] RO filter membranes are an important component of RO reverse osmosis water treatment equipment. Reverse osmosis technology is a membrane separation and filtration technology that uses pressure difference as the driving force. Under pressure, H2O molecules can pass through the RO membrane, while inorganic salts, heavy metal ions, organic matter, colloids, bacteria, viruses and other impurities in the source water cannot pass through the RO membrane, thereby strictly distinguishing between pure water that can pass through and concentrated water that cannot pass through. In high-tech glass greenhouses, RO purified water is an important irrigation equipment. A good water source is an essential link in achieving precise irrigation. As an essential and important equipment component in this link, the RO membrane needs to be replaced regularly according to the quality of the raw water.

[0003] Due to the unique construction of RO equipment, each filter membrane is stacked vertically, achieving purification through layer-by-layer filtration in a specifically designated flow direction. This process limits the membrane replacement process, requiring each layer of RO membrane (typically about 6 meters long, with two layers totaling 12 meters) to be removed one by one from top to bottom. After the replacement membranes are installed, they are then reinstalled one by one in the original order. Due to the limited site area and space, RO membrane replacement typically requires the use of electric equipment such as forklifts. Due to the unique placement of materials in greenhouse functional areas, other greenhouse equipment such as mother liquor tanks, fertilizer spreaders, sterilizers, and air compressors often need to be located nearby, increasing the risk of damage from forklift operation. Diesel forklifts can easily generate significant exhaust emissions in a confined space, contaminating the growing materials and potentially impacting the health and safety of construction workers. Some existing filter replacement techniques use hooks driven into the ceiling above the RO equipment, but this method is not suitable for all sites. First, there is no guarantee that the roof above the RO equipment is strong enough to implant the hooks. Secondly, the hooks cannot be moved after implantation. If the placement of the equipment changes later, the hooks need to be re-implanted. The previous hooks will also affect the overall aesthetics of the greenhouse functional area.

[0004] Therefore, in order to solve the above problems, the present invention urgently needs to provide a steel frame for replacing RO filter membrane in a narrow space. Utility Model Content
