NON-POWERED ROTATION FILTERING APPARATUS }

The present invention relates to a non-powered rotary filtration device in which a cylindrical filter is rotated by fluid flow without separate power being supplied, and foreign substances accumulated in the rotating cylindrical filter are sucked into a foreign material suction unit to reduce the load on the cylindrical filter. will be.

In general, a filtration device filters foreign substances from water (hereinafter referred to as 'raw water') containing foreign substances such as rust, scale, and larvae using a filter, and discharges filtered raw water (hereinafter referred to as 'purified water'). will do

However, when such a filtration device is used for a long period of time, the pores of the filter are clogged and the filter performance is deteriorated.

In order to solve this problem, a backwash filtration device is used to extend the filter life.

In general, a backwash filtration device performs a filtration process of supplying purified water by filtering water containing foreign substances through a filter, and a backwashing process of removing and discharging foreign substances accumulated in the filter during the filtration process.

However, since the filtration process cannot be performed during the backwashing process in the backwashing filtration device, that is, the backwashing process cannot be performed simultaneously with the filtration process, the backwashing process is limitedly performed very rarely.

Therefore, in the backwashing filtration device, foreign substances penetrate deeply into the inside of the filter during the long-term filtration process, and there is a high risk that the foreign substances will not be removed during the backwashing process. will lower the

The operation of the present invention as described above will be described.

Water ('raw water') containing foreign substances such as rust, scale, and larvae flows into the raw water inlet chamber 110 of the casing 100 through the raw water inlet pipe 111 .

The raw water introduced into the raw water inlet chamber 110 rotates the rotary shaft 210 to which the rotary blade 220 is coupled while flowing through the filtration treatment chamber 130 through the lower fluid flow port 122 of the lower partition wall 120 .

Accordingly, the lower filter support 230, the upper filter support 240, and the cylindrical filter 250 coupled to the rotation shaft 210 are rotated together.

As the raw water introduced into the filtration chamber 130 flows into the cylindrical filter 250 through the cylindrical filter 250 , various foreign substances are filtered by the cylindrical filter 250 .

Water from which foreign substances have been filtered, ie, purified water, flows into the purified water outlet chamber 150 through the upper fluid flow port 241 of the upper filter support 240 , and then is discharged to the outside through the purified water outlet pipe 151 .

On the other hand, the foreign substances filtered by the cylindrical filter 250 are rotated together with the cylindrical filter 250 and receive centrifugal force, and when raw water is sucked through the foreign material suction pipe 161, it is sucked together into the foreign material suction pipe 161, and the foreign material suction connection pipe ( 162) to the outside.

That is, in this non-powered rotary filtration device, foreign substances accumulated in the cylindrical filter 250 may be discharged to the outside through the foreign material suction unit 160 even while the raw water is filtered.

The suction and discharge of foreign substances to the outside through the foreign substance suction unit 160 may be made continuously or periodically.

For example, an automatic valve (not shown) for automatically opening and closing a flow path is provided in the connection pipe 162 for inhaling foreign substances, so that foreign substances can be automatically sucked and discharged to the outside.

At this time, the automatic valve (not shown) may be opened and closed periodically by a timer or operated by the differential pressure of raw water and purified water.

On the other hand, the present invention can perform the backwashing process like the conventional backwashing filtration device. However, in the present invention, since the deterioration of the performance of the cylindrical filter 250 is delayed by the foreign material suction unit 160, the cycle of the backwashing process can be prolonged.

Describe the backwashing process.

Close the valve (not shown) connected to the raw water inlet pipe 111 to prevent the inflow of raw water, and close the valve (not shown) connected to the foreign substance suction unit 160 to prevent the raw water including foreign substances from being discharged. When backwashing water is supplied through the outlet pipe 151 , the backwashing water flows into the cylindrical filter 250 , and the backwashing water passes through the cylindrical filter 250 from the inside to the outside to backwash, and then backwashed water through the drain pipe 112 . This is discharged to the outside.
