Description

Technical Field

[0001] The utility model relates to the technical field of reverse osmosis equipment, in particular to a reverse osmosis equipment for water production. Background Art

[0002] Water production generally refers to the conversion of raw water into water that meets the standards for specific uses through various water treatment technologies. These uses can be drinking water, industrial water, and medical water. The water production process involves multiple steps and technologies, including pretreatment, filtration, disinfection, and post-treatment.

[0003] At present, reverse osmosis equipment is used in the water production process. Reverse osmosis technology can effectively remove dissolved solids, organic matter, bacteria, viruses and other impurities in water. When the existing reverse osmosis equipment for water production is used, the raw water is filtered from the water tank through the primary filter plate for the first time, and then enters the two filter boxes to pass through the other two filter plates for the second and third filtration. However, a large amount of dirt will be generated during the first filtration of the raw water. When cleaning the primary filter plate, two motors are started at the same time. The motor drives the drive shaft to rotate, thereby rotating the gear in the installation cavity. Since there are strip grooves on both sides of the primary filter plate and they are fixedly connected to the rack, the rack and the gear The gears are engaged, and the primary filter plate rises and is removed from the inner cavity of the water tank for cleaning. After cleaning, the primary filter plate is installed in the groove at the top of the water tank. However, when the existing reverse osmosis equipment for water production drives the primary filter plate to rise and fall through the gear and rack, natural wear will occur between the gear and the rack after long-term use. This wear will cause loose engagement and affect the lifting accuracy of the primary filter plate. Therefore, the gears need to be repaired, but the water tank and the cover plate are currently fixed with bolts. Each time the gears are repaired, the bolts need to be removed and reinstalled, which increases the operation time and complexity. Frequent disassembly and assembly may cause the bolts to loosen or seal poorly, affecting the sealing performance of the system.

[0004] Therefore, it is necessary to provide a new water-making reverse osmosis equipment to solve the above-mentioned technical problems. Utility Model Content
