A small device for preparing drinking water by manual pressurization

technical field

The invention is a small device for preparing drinking water by manual pressurization. The device can use manual pressurization to prepare drinking water during lifesaving at sea, field survival or emergency rescue.

Background technique

At present, commonly used small devices for preparing drinking water are generally composed of three parts: pre-filtration (coarse filtration), adsorption, and membrane filtration (microfiltration, ultrafiltration, reverse osmosis). Among them, adsorption (usually activated carbon adsorption) and membrane filtration are the main means to remove organic matter, odor and color in water. Its weak point of these small-sized devices of preparing drinking water is that power depends on electric energy, can't run when there is no power supply, and weight, volume are still bigger, can not carry.

Contents of the invention

The purpose of the present invention is to provide a small device for preparing drinking water by manual pressurization. It adopts artificial power and breaks away from the dependence on electric energy. emergency care etc.

In order to achieve the above object, the present invention adopts the following technical solutions. The device includes a first force arm, a second force arm and a pressurized piston. There are upper and lower cavities in the first force arm, an ultrafiltration component is arranged in the lower cavity, and an activated carbon component is set in the upper cavity. There is a cavity in the second force arm, and a reverse osmosis component is arranged in the cavity, and a water outlet is also set on the second force arm, and a water inlet cavity communicated with the water inlet is arranged in the pressurizing piston. Between the lower cavity of the first force arm and the water inlet cavity of the pressurized piston, between the upper and lower cavities of the first force arm, and between the upper cavity of the first force arm and the cavity of the second force arm are respectively communicated through pipelines, The water inlet pipe of the pressurized piston is provided with a one-way valve.

Both ends of the pressurizing piston are respectively hinged to the first moment arm and the second moment arm, and one end of the first moment arm and the second moment arm are also hinged.

The present invention has the following advantages:

1) The invention adopts a completely manual piston pressurization, which gets rid of the dependence on electric energy;

2) The invention is simple in operation, small in size and light in weight, and can be carried with you to prepare drinking water for sea lifesaving, field survival, emergency rescue, etc.;

3) The present invention adopts the ultrafiltration membrane as the pretreatment device, which has a good treatment effect and can remove most of the suspended matter colloids and some bacteria, and does not need to add any coagulants, scale inhibitors, and bactericides, and does not produce secondary pollute;

4) The present invention is applicable to a wide range of raw water quality, and is applicable to the preparation of drinking water using seawater, brackish water, and polluted surface water as water sources, and the quality of the effluent water meets the requirements of the "National Drinking Water Sanitation Standard";

Detailed ways

Below in conjunction with accompanying drawing 1～Fig. 2 the present invention will be further described:

The device adopts manual piston pressurization, and has three-level processing units including ultrafiltration components, activated carbon components, and reverse osmosis components. Its specific structure is shown in FIG. 1 and FIG. 2 , including a first force arm 5 , a second force arm 6 and a pressurizing piston 1 . One end of the first moment arm 5 is hinged with one end of the second moment arm 6, and the two ends of the pressurizing piston are respectively hinged with the first moment arm 5 and the second moment arm 6, so that the whole device forms a foldable structure , Small size, easy to carry.

The structure of the pressurized piston is shown in Figure 2, including a water inlet chamber and a piston that can move up and down in the water inlet chamber. The water inlet pipe 11 communicates with the water inlet chamber, and a filter head 14 is arranged on the water inlet pipe 11.

As shown in Figure 2, two upper and lower chambers are arranged in the first arm 5, an ultrafiltration assembly 2 is arranged in the lower chamber, an activated carbon assembly 3 is arranged in the upper chamber, and the lower chamber of the first arm 5 is connected with the The water inlet chambers of the pressure piston 1, and the upper chamber and the lower chamber are respectively connected through pressure-bearing hoses, and the water inlet pipe of the pressure piston is provided with a one-way valve.

There is a cavity in the second arm 6, which communicates with the lower cavity of the first arm through a pressure-bearing hose. A water outlet is arranged on the side wall of the second arm of force 6, and a reverse osmosis assembly 4 is arranged in the cavity of the second arm of force. 12 is provided with pressure reducing valve.

When in use, first pull the pressurizing piston 1 apart, at this time water is sucked into the water inlet chamber of the pressurizing piston 1, and then forcefully close the pressurizing piston 1, continuously pull and press the piston, and the water flow will be pressed into the supercharger in turn. In the filter assembly 2 , the activated carbon assembly 3 and the reverse osmosis assembly 4 , the prepared drinking water flows out from the outlet pipe of the reverse osmosis assembly 4 .

The water flow is pressed into the ultrafiltration membrane module, and the suspended matter colloid and some bacteria in the water are retained. Then, the water flows into the activated carbon module, and some small molecular organic substances in the water are adsorbed by the activated carbon. Finally, the remaining small molecular substances, dissolved ions and water flow enter the core processing unit - the reverse osmosis component, where a cross-flow form is adopted, and the remaining small molecular substances and dissolved ions are separated and removed and discharged through a water outlet pipe to prepare drinking water. Water flows out from another outlet pipe.
