Embodiment 1
[0033] Embodiment 1: as figure 1 As shown, the device is composed of a pressure tank, an air cylinder, a micro-mesh filter and a membrane filter connected by pipes and valves, wherein:
[0034] The inflatable cylinder 1 is cylindrical and is composed of a pull rod, a plastic shell and an air outlet pipe. The mouth of the air outlet pipe is connected to the air inlet pipe on the top of the pressure tank 2;
[0035] The pressure barrel 2 is in the shape of an ellipsoid, and is connected by a plastic shell, a plastic top cover, an air inlet pipe and an outlet pipe 3. There is a gap between the nozzle at the bottom of the water pipe 3 and the bottom of the pressure tank 2;
[0036] The upper part of the micro-filter filter 5 is cylindrical and the lower part is truncated. It is composed of a micro-filter element 6, a backwash valve 11 and a metal shell. The mesh filter element 6 is located in the middle and connected to the top of the metal shell, and its right end is connected ...

Abstract
The invention relates to an unpowered emergency water purifier applicable to earthquake stricken areas. The unpowered emergency water purifier comprises a pressure barrel, an inflator pump, a micro-screen filter and a membrane filter, which are connected through pipelines and valves, wherein the pressure barrel is provided with an air inlet pipe and a water outlet pipe and is connected with the air inlet pipe and the water outlet pipe through a plastic top pipe; during the operating process of the pressure barrel, raw water flows into water outlet pipe and then flows out of the water outlet pipe via the bottom end opening of the water outlet pipe by virtue of differential pressure generated by the inflator pump; the micro-screen filter has a cylindrical upper part and a circular truncated cone-shaped lower part and comprises a micro-screen filter element, a back washing valve and a metal casing; the micro-screen filter element is fixed in the middle of the micro-screen filter; the micro-screen filter operates in such a way that water flows into the micro-screen filter from the left end and flows out of the micro-screen filter from the right end; the membrane filter is cylindrical and comprises a hollow fibrous membrane, a main water outlet pipe and a stainless-steel casing; the hollow fibrous membrane is fixed at the top end of the membrane filter and connected with the water outlet pipe; and raw water flows out of the main water outlet pipe after being filtered by the micro-screen filter and the membrane filter. The unpowered emergency water purifier does not need to be provided with extra power, and is high in water purification speed, high in purified water quality, convenient to carry and transport and suitable for being used in places which are badly in need of drinking water, such as earthquake stricken areas.
Description
technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a non-powered emergency water purifier suitable for post-earthquake disaster areas. Background technique [0002] After the earthquake, the urban water supply systems in the hardest-hit areas were basically completely paralyzed, and the water supply systems in surrounding cities would also be damaged to varying degrees. Emergency engineering repairs often take several days. In the process of leak detection and repair of damaged water supply pipes, how to temporarily provide water supply facilities or drinking water for the victims is particularly important. [0003] The lack of sanitary drinking water in the earthquake-stricken areas is mainly caused by the following three reasons. [0004] (1) The earthquake caused the original water pipes to burst and be damaged, thereby paralyzing the water supply system. [0005] (2) During the earthquake, a large area o...
