 In the water purification process for various water treatments, pretreatment before advanced treatment (ie, activated carbon, ozone, photocatalyst, membrane separation treatment) in various filtration and wastewater treatment to remove various suspended matters, or water used as primary Microfilters are used to filter suspended solids in fluids (especially water) for the purpose of recycling.

In addition, various filtration devices have been applied to general household water purifiers.

The precision filtration device used for this purpose is manufactured to a certain size of the pore structure of the filter that performs the filtration, so if the pores are blocked by the filtered contaminants after a certain period of time, backwashing is impossible or the rate of recovery of the backwash is extremely low. Therefore, most microfiltration devices have to replace the filter at regular intervals.

In addition, if the backwash is to change the pores of the filter layer only by aerosols, there is no effect of vibration, etc., the efficiency of removal of foreign matters, the backwashing cycle is faster, resulting in a high consumption of fresh water.

The present invention is to provide an upflow filter device having a filter unit and a settling unit in view of the above problems.

The present invention has a filter layer which can filter and backwash the suspended solids contained in the fluid with high precision, and the filtration unit which provides filtration and backwashing conditions under uniform conditions by installing electromagnets and permanent magnets at specific parts of the filtration section. In order to provide a filtration and backwashable upflow filtration apparatus which can form uniformly treated water under constant conditions, while sedimentation tank is formed integrally with the lower part of the filtration unit to precipitate and remove the material having a specific gravity in the inflow water. .

The filtration device of the present invention changes the pressing direction of the filter in the upward flow type, and electromagnets and permanent magnets are installed at specific parts of the filter unit to perform filtration under uniform conditions at all times. The present invention relates to a precision filtration device having a structure capable of discharging sediment to the lower part and performing filtration only of the supernatant water, and discharging the entire amount of the contents to the lower part when backwashing. The lower housing of the filter part is conical to form a vortex at the settling part to give a centrifugal separation function to precipitate and remove iron powder, rust powder, and sand remaining in the muddy water before it filters the influent. By filtration only with supernatant water, it can extend the life of the filter, prevent frequent breakdowns, and increase the backwash cycle, thereby extending the filtration time and ultimately providing a filtration device that can obtain high quality water while finding economical efficiency. will be.

Existing downflow filtration system accumulates inside the filter without its outlet when heavy materials (iron powder, rust, muddy water, sand, etc.) with a specific gravity flow in, causing the filter layer to fail and backwashing with strong air. In the city, the microfiber filter was damaged, shortening the life of the filter, causing frequent failures, speeding up the replacement cycle of the filter, and obtaining a uniform filtered water quality.

In order to solve the above problem, the existing filtration device was installed in front of the filtration tank to install a separate sedimentation tank to precipitate the mud component in the sand or muddy water with a specific gravity, and the only supernatant was sent to the filtration tank to be used.

In addition, in the prior art, a filtration device which is intended to be carried out in a reaction tank that has been partially filtered and backwashed has been disclosed. However, in the conventional filtration device, when raw water is introduced, a filter layer made of fibers or weft yarns is sufficiently compressed when the filter layer is compressed with water pressure. When the supply of raw water continues to be filtered normally, the filter layer is re-injured with elasticity and buoyancy, and then the raw water is re-injected. In this case, since the discharge environment is changed from time to time according to the surrounding conditions, the compressed layer is formed again according to the water pressure, so that the initial water quality and the middle water quality are discharged differently, resulting in inconsistent and stabilization of the water quality.

 Applicants made several devices and tried various methods to solve this problem. Among them, the tester was able to obtain a certain standard of water quality by using electromagnets or permanent magnets. As a result, it was confirmed that the life of the filter can be greatly improved, and the present invention was completed.

 Therefore, the present invention has been made in view of the problems of the prior art, the object of which is to provide a constant treatment water at all times by providing an electromagnet and a permanent magnet in the filtration device at the time of filtration or backwashing of the fluid, and also the filtration unit and the precipitation unit integral The present invention is to improve the life of the filter significantly by providing an upflow filter device.

The filtration device of the present application is installed so that the raw water is introduced with a downward slope from the bottom of the filtration device, the inflowing raw water forms a vortex to the bottom, and the foreign matter having a specific gravity such as sand precipitates and is removed to the bottom, and the supernatant water removes the filter layer. Filtration through the filter layer, the filter layer is pressed by the water pressure of the raw water inflow water, and the filter position is fixed by the magnetic force response when the specific part of the upper end is reached. It is formed to form a constant pressure layer without being affected by other conditions such as water pressure to achieve a filtration device that can provide filtered water of uniform water quality.

In the case of backwashing, when backwashing water is injected through the treated water outlet, the compressed filter layer is returned to the lower part of the filtration cylinder. At this time, air is injected into the fallopian tube of the fallopian tube to form turbulence by air bubbles. Create up and down vibrations, or variable filter layers work on specific areas. The electromagnet is installed outside the filtration device container so that it can be applied, and the upper roller part retains the corresponding magnetic force to guide the variable filter layer inside the container to form up and down vibrations to completely discharge the contaminants caught between the filters. A structure is implemented.

In addition, the filtration device of the present application can be applied to the domestic water purifier, industrial water purifier as much as a pre-treatment device, and can be used to apply to the filtration device that always provides a stable water purification uniformly using an electromagnet.

In order to achieve the above object, the present application forms a cylindrical shape of the structure surrounding the filter layer in the upper part of the filtration device by filtration and backwashing the suspended solids contained in the fluid and the lower portion of the conical funnel structure to form the raw water filtration device The inflow of raw water flows in a downward slope from the bottom of the stream, and the inflow of raw water forms a vortex at the bottom and turns, while foreign matters having a specific gravity such as sand are removed by sedimenting to the bottom. When the filter layer is pressed and the specific position at the top is reached, the filter position is fixed by magnetic force sensitivity so that a constant pressure layer can be formed at all times without being affected by other external conditions such as water pressure. In backwashing with flushing water through the water outlet, the filter The air drawn from the air inlet pipe in the lower part of the filtration device in the state returned to the position injects the dispersed air through the flap-shaped air injection pipe and forms turbulence by the air bubbles and forms the up and down vibration, or the variable filter layer Works on the site. The electromagnet is installed outside the filtration device container so that it can be applied, and the upper roller part retains the corresponding magnetic force to guide the variable filter layer inside the container to form up and down vibrations to completely discharge the contaminants caught between the filters. It is to provide a method of carrying out.

In addition, the present application forms a cylindrical shape in the filtration device that performs the filtration and backwashing function to form a cylindrical shape of the structure surrounding the filter layer in the upper filtration device to perform the filtration and backwashing function and to form a conical funnel structure at the bottom to precipitate the suspended matter The raw water inlet pipe is installed to make a downward slope at the bottom of the filtering device, an electromagnet is installed at a specific part outside the filtering device, and a permanent magnet is installed at the lower holder part of the filtering device so that they are interconnected. When performing filtration or backwashing, the filter layer is fixed to a desired position so that a constant compression layer is always formed without being affected by water pressure or the flow of fluid to obtain a certain quality of filtered water or backwashing. It is to provide a device.
