Nanofiltration membrane water purifier

Abstract

The present invention provides a nanofiltration membrane water purifier, and relates to the technical field of nanofiltration membrane water purifiers, the nanofiltration membrane water purifier comprises a main body, a pressurization assembly and a filtration assembly, the main body is internally provided with a filtrate bin, the top of the filtrate bin is provided with a water inlet, one side of the top of the main body is provided with a driving block, the driving block is internally provided with a lithium battery, and one side of the driving block is provided with a switch, the switch is electrically connected with the lithium battery, and the pressurization assembly is arranged in the main body and used for pressurizing and accelerating liquid passing through the filtrate bin. According to the water purifier, through the outer-layer nanofiltration membrane and the inner-layer nanofiltration membrane which can be provided with the through-flow holes in a staggered mode, the filtering precision of the device is improved, the applicability of the device is improved, meanwhile, water flow in the filtrate bin can be stirred to form vortexes when the pressurizing plate rotates, and the situation that the water flow is difficult to pass through the inner-layer nanofiltration membrane and the outer-layer nanofiltration membrane due to too small force is avoided.

Description

technical field [0001] The invention relates to the technical field of nanofiltration membrane water purifiers, in particular to a nanofiltration membrane water purifier. Background technique [0002] Nanofiltration membrane is a kind of functional semi-permeable membrane that allows the permeation of solvent molecules or some low-molecular-weight solutes or low-valent ions. It is a special and promising membrane. The type of separation membrane, it is named because the size of the material that can be retained is about nanometers. [0003] Because nanofiltration membranes can perform relatively precise filtration, they can be widely used to remove organic matter and chromaticity of surface water, remove the hardness of groundwater, partially remove soluble salts, concentrate fruit juice and separate useful substances in medicines, etc. In people's lives, there are also many water purifiers that use nanofiltration membranes for filtration. Since the tap water supplied by th...

[0004] However, the water provided by a single faucet can be used for a variety of purposes, such as for drinking purposes and for cooking, etc. The purity of these waters is relatively high, while the purity of water used for washing your face or for daily purposes such as brushing your teeth requires a higher purity. It’s not that high, and the nanofiltration membrane water purifiers that are common on the market do not have the function of adjusting the filtration precision. If the precision is too low, it will be difficult for drinking water to meet the standard, and if the precision is too high, it will lead to the slow flow of domestic water, which is difficult to obtain. The applicability of adjusting according to the actual use requirements is low. At the same time, the common nanofiltration membrane water purifiers on the market cannot pressurize the water source, resulting in poorer water output due to the smaller filter pores of the nanofiltration membrane during the filtration process. Slow, users often need to wait for a long time to fill up the required water, low filtration efficiency affects the use of users
