Problems solved by technology
[0004] Based on this, it is necessary to solve the problem that the pressure difference between the two sides of the above-mentioned hollow fiber ultrafiltration membrane is relatively large, resulting in the rupture of the hollow fiber to the filter membrane, and to provide a water outlet regulator for the ultrafiltration machine that can reduce the pressure difference between the two sides of the hollow fiber ultrafiltration membrane.

Embodiment Construction
[0032] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0033] It should be noted that when an element is referred to as being “disposed on” another element, it may be directly on the other element or there may also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only and are not intended to represent the only embodiments.
[0034] Unless otherwise defined, all technical and scientific ter...

The invention relates to an effluent adjusting device of an ultrafilter. The effluent adjusting device of the ultrafilter is placed at a clean water outlet end of the ultrafilter. The effluent adjusting device of the ultrafilter comprises a body, a water inlet end and a water outlet end, wherein the water inlet end is located on one end of the body, the water outlet end is located on the other end of the body, the water outlet end and the water inlet end are communicated to form a first flow guide channel, and an opening of the water inlet end is larger than that of the water outlet end. After the effluent adjusting device of the ultrafilter is arranged at the clean water outlet end of the ultrafilter, a water flow filtered through a hollow fiber ultrafiltration membrane of the ultrafilter enters between the clean water outlet ends. The water flow enters the effluent adjusting device of the ultrafilter, and the water pressure will be increased after the water flow enters the flow guide channel of the effluent adjusting device of the ultrafilter, so that a back pressure region is formed near the water inlet side of the water inlet end, and therefore, the pressure difference between the two sides of the hollow fiber ultrafiltration membrane is reduced to prevent the hollow fiber ultrafiltration membrane from being broken, and the service life of the hollow fiber ultrafiltration membrane is prolonged.
Description
technical field [0001] The invention relates to the field of water purification, in particular to an ultrafilter outlet water regulating device and an ultrafilter. Background technique [0002] At present, ultrafiltration is a pressurized membrane separation technology. Under the condition of certain pressure and the pressure difference of hollow fiber ultrafiltration membrane, small molecular solutes and solvents pass through a special hollow fiber ultrafiltration membrane with a certain pore size. Make macromolecular solutes impenetrable and stay on the outside of the hollow fiber ultrafiltration membrane. [0003] Since the hollow fiber ultrafiltration membrane has been in a state where the pressure difference between the outside and the inside is relatively large for a long time, the hollow fiber ultrafiltration membrane will rupture due to the excessive pressure difference between the inside and outside of the hollow fiber ultrafiltration membrane, which will damage the...
