Pressure-regulating backwash ultrafiltration tube and canteen as well as use method thereof

Abstract

The invention discloses a pressure-regulating backwash ultrafiltration tube and a canteen as well as a use method thereof. Particularly, the pressure-regulating backwash ultrafiltration tube is arranged in the canteen and comprises an ultrafiltration tube body, an ultrafiltration element, a cross tube, a wave tube water purifying nozzle and a pressurizing device; middle threads of the ultrafiltration tube body are connected with a mouth of the canteen; a first gas inlet is formed in the lower part of the middle threads of the ultrafiltration tube body; the tube inner wall below the first gas inlet is connected with the ultrafiltration element; a center hole is formed in the inner cavity in the middle part of the ultrafiltration tube body; a second gas inlet, a water sealing collar, an internal screw port and an external screw port are also sequentially formed from the center hole in the middle part of the ultrafiltration tube body to the outer side; the center hole is also connected with the cross tube; the upper part of the cross tube is connected with a wavelet nozzle; the pressurizing device is also arranged at the upper part of the ultrafiltration tube body. The pressure-regulating backwash ultrafiltration tube and the canteen disclosed by the invention, adopting the structure, can use multiple modes of obtaining raw water and purified water and can also be back washed, sothat service functions of the canteen can be added; the pressure-regulating backwash ultrafiltration tube and the canteen have the advantages of simple and reasonable structure and labor saving and convenience in use and can be used for field emergency survival of a military product or a civilian product.

Description

technical field [0001] The invention relates to a pressure-regulating backwashing ultrafiltration tube and a military kettle, in particular, the pressure-regulating backwashing ultrafiltration tube is installed on the military kettle. Background technique [0002] Various types of outdoor portable water purifiers in the prior art can be used when people go out to meet emergency disaster relief or even solve difficulties for survival, so they are highly praised. However, if it is used as a technology and product for military-civilian integration, it is necessary to combine civilian water purification technology with military kettles commonly used in the military to expand its use functions in order to cope with various more complex special environments. [0003] Commonly there are two types in its prior art: one is the subjective improved type, that is, the existing military kettle is partially improved, and water purification technology and components are added. For example,...
