Abstract

The invention relates to portable filters for obtaining drinking water from surface sources and allows for compactness and lightness of the device. The filter consists of a housing 1 with inlet and outlet connections and a piston installed in the housing. The piston consists of a hollow cylinder, the ends of which are covered with perforated lids, above the top of which there is a flap valve. Filtering layers 13 and 14 are located in the piston. When the piston moves upwards, the lower part of the body is filled with liquid, while the piston moves downward, the water passes through the filtering layers and the cleaned out comes through the pipe 6. 1 Cp f-ly. 1 il. five

Description

t1

The invention relates to the filtration of liquids and low concentrated suspensions and can be used to obtain drinking water, for example, from surface sources.

The purpose of the invention is to ensure the compactness and lightness of the device.

The drawing shows the filter section.

The filter consists of a cylindrical vertical body 1 with a bottom 2 and a cover 3, a piston and a rod 4 with a handle 5.

The housing 1 has a discharge pipe 6 and a thread for the bolt 3. The bottom 2 has a check valve 7 mounted in the feed pipe 8. The removable cover 3 has a seal 9. The piston 10 consists of a hollow cylinder with perforated covers 11, above which is a petal valve 12. Inside the piston there is a filter 13 and a sorbent 14 layers separated by a mesh diaphragm 15.

The filtering device operates as follows.

In the initial position, the piston is at the bottom, and the flap valve 12 is closed. When the piston moves upwards, the check valve 7 opens and the water fills the lower volume of the housing 1. When the piston moves down, the valve 7 closes, and the lobe valve 12 opens, the water is forced through the filtering 13 and the sorbent 14 layers, clears and fills the volume of the housing 1 above the piston. The next upward movement of the piston 10, the petal valve 12 closes, the valve 7 departs from the editor P. Geresi

the bottom volume of the housing 1 is filled with a new portion of water, and the purified water through the nozzle 6 is supplied to the consumer.

Further, these cycles are repeated many times until the protective power of the filtering and sorbing layers 13 and 14 is exhausted (until their

pores and deterioration of cleaning). To replace the latter, open the cover 3, remove the piston with the help of the stem 4, open the perforated cover 11 and replace layers 13 and 14.

The assembly of the filter device is performed in reverse order.

Claims (2)

1. A portable filter for the purification of drinking water, comprising a vertical cylindrical body with several filter layers, supply and discharge connections, a check valve installed in the supply connection, and means for creating movement of water through the filter layers, executed in the form of a piston, characterized in that To ensure the compactness and lightness of the device, the piston is made in the form of a hollow cylinder, the ends of which are blocked by perforated claws, the filtering layers are located in the piston and a petal valve is installed above the upper perforated cover. 2. Filter POP.1, differing from that by the fact that one of the filter layers is made of sorbent.
