1 is a schematic sectional view showing a filter device according to an embodiment of the present invention. FIG. 2 is a schematic cross-sectional view showing a state in which the filter device shown in FIG. 1 filters liquid. FIG.

1 and 2, a filter device 100 according to an embodiment of the present invention includes a body 110, a first tube 120, a second tube 130, a third tube 140, And a ball 150.

The body 110 has hollow spaces 112 and 114 therein. The hollow spaces 112 and 114 are filled with filtration material through which the liquid passes and the contaminants to be filtered are removed. The filtration material may be a disk assembly 160 through which a liquid is passed and filtered as described below, and may include both the disk assembly 160 and other filtration materials.

The body 110 may include an upper body 110a and a lower body 110b. The upper body 110a may include an inner partition wall 113 for separating the first tube 120, the second tube 130 and the inner hollow portion 112 from the outer hollow portion 114. The third tube 140 may be formed on the lower body 110b. The upper body 110a and the lower body 110b may be coupled to each other through a bolting method. However, the body 110 of the present invention is not limited to the coupling relationship of the upper body 110a, the lower body 110b, and the two bodies 110. [

The liquid flows from the outside of the body 110 and passes through the filtration materials filled in the hollow spaces 112 and 114 provided inside the body 110 to remove the contaminants and the filtered liquid passes through the body 110, And is discharged to the outside. Here, the liquid may be water. The filter device 100 may be a device for filtering the irrigation water supplied to the fruit or garden. On the other hand, the filter device 110 according to an embodiment of the present invention can filter about 20 tons of water per hour.

The hollow spaces 112 and 114 may include an inner hollow portion 112 and an outer hollow portion 114 formed to communicate with each other at a lower end thereof.

The inner hollow portion 112 is formed at the center of the body 110 and is filled with filtration material. The inner hollow portion 112 communicates with the second tube 130 to be described in detail later. The inner hollow portion 112 may be filled with the filtration material so that the liquid introduced from the outside may be filtered and then discharged to the outside of the filter device 100 through the second pipe 130. As described above, the filter material may be a disc assembly 160 formed by stacking a plurality of porous discs. In the case where the hollow spaces 112 and 114 do not include the inner hollow portion 112 and the outer hollow portion 114 but are formed as one space, the first to third pipes 120 to 140 And may be formed to communicate with the hollow spaces 112 and 114.

The outer hollow portion 114 is formed to surround the inner hollow portion 112. The outer hollow portion 114 and the inner hollow portion 112 may be partitioned by the inner partition 113. The outer hollow portion 114 is formed to surround the entire inner hollow portion 112 along the longitudinal direction of the inner hollow portion 112. The outer hollow portion 114 is formed to communicate with the first tube 120.

The disc assembly 160 may be disposed to fit within the inner hollow portion 112. In addition, the disc assembly 160 may extend downwardly and be formed adjacent to a lower portion of the body 110. The disc assembly 160 may be formed by laminating disc-shaped donut-shaped discs. This will be described in detail with reference to FIG. The liquid passes through the disc assembly 160 and various contaminants are removed. The removed contaminants may be caught or attached to the disc assembly 160.

The first pipe 120 communicates with the hollow spaces 112 and 114 and injects the liquid required for filtration into the hollow spaces 112 and 114 or the hollow space 112 and 114 through the third pipe 140. So that the injected liquid is discharged. The first pipe 120 is formed to communicate with the external hollow portion 114 so that the liquid flowing into the first pipe 120 fills the external hollow portion 114 and flows along the internal hollow portion 112. However, unlike the case shown in the drawing, when the hollow spaces 112 and 114 are formed without distinguishing between the inner hollow portion 112 and the outer hollow portion 114, the first pipe 120 is divided into the hollow spaces 112 and 114, And can be formed in communication with each other.

The second tube 130 communicates with the hollow spaces 112 and 114 and is formed at a different position from the first tube 120 and passes through the hollow spaces 112 and 114 to discharge the filtered liquid. The second tube 130 may be formed to communicate with the inner hollow portion 112. The second tube 130 may be configured such that when the filter device 100 is cleaned, the second tube 130 is closed so that liquid does not enter and exit. The blocking mesh 170 may be disposed at a portion where the second pipe 130 and the inner hollow portion 112 meet so that the cleaning ball 150 does not flow out through the second pipe 130 to the outside.

The cleaning ball 150 is provided inside the hollow spaces 112 and 114 and sinks to the lower portion when the liquid is injected into the first tube 120 and floats to the upper portion when the liquid is injected into the third tube 140, It can strike the material and vibrate. Where the filtration material may be the disk assembly 160 described above. Vibration of the cleaning ball 150 and the filtration material can separate contaminants from the filtration material. The contaminants may be discharged to the first pipe 120 through the external hollow portion 114 by the liquid flowing from the third pipe 140.

The third tube 140 communicates with the hollow spaces 112 and 114 and is formed at the lower portion of the body 110 to inject high pressure liquid into the hollow spaces 112 and 114. The third tube 140 is configured such that the filter device 100 is clogged when the liquid is filtered. The third pipe (140) is opened when the filter device (100) is washed, and high pressure liquid for washing is injected. The third tube 140 may be formed to be narrower than the first tube 120 and the second tube 130. This is because the liquid flowing into the filter device 100 flows into the high pressure.

The cleaning balls 150 may be disposed in the hollow spaces 112 and 114 adjacent to the third tube 140. The cleaning balls 150 may be disposed within the disc assembly 160. Meanwhile, the blocking net 170 may be disposed on the body 110 adjacent to the third pipe 140 so that the washing ball 150 does not protrude toward the third pipe 140.

However, in the case where the disc assembly 160 is not provided or the disc assembly 160 is shortly provided without extending to the lower portion of the body 110, unlike the one shown in the drawing, The cleaning balls 150 are attached to the boundary between the tube 140 and the hollow spaces 112 and 114 in a process of filtering the liquid through the filter device 100 or a process of cleaning the filter device 100, A blocking screen 170 may be provided so as not to be discharged to the outside. The diameters of the first to third pipes 120 to 140 may be smaller than the diameter of the cleaning balls 150 in order to prevent the cleaning balls 150 from being discharged to the outside of the body 110 .

Hereinafter, with reference to FIG. 2, a description will be given of a manner in which the filter device 100 according to an embodiment of the present invention filters liquid.

The liquid required for filtration is introduced into the filter device 100 through the first pipe 120 (a). The liquid can move downward along the outer hollow portion 114 (b). The liquid in the outer hollow portion 114 flows into the inner hollow portion 112 and passes through the disk assembly 160 and can be primarily filtered. As the liquid continues to flow, the liquid is drawn into the hollow spaces 112 and 114 (c). Then, the liquid is discharged to the outside through the second pipe 130 communicated with the inner hollow portion 112 (d).

The liquid that needs to be filtered through the first pipe 120 flows at a comparatively high pressure, so that it can collide with the inner partition wall 113 and move downward according to gravity. And can pass through the disc assembly 160 and into the disc assembly 160 while moving downward. The liquid passes through the disc assembly 160 and is filtered.

It is preferable that the cleaning ball 150 is formed to have a specific gravity larger than that of the liquid flowing into the body 110. This is to prevent the washing ball 150 from floating in the liquid phase introduced through the first pipe 120. The cleaning ball 150 hits the disc assembly 160 and removes contaminants attached to the disc assembly 160 through vibration. Therefore, it is preferable that the cleaning ball 150 is laid under the body 110 in the process of filtering the liquid by the filter device 100, and does not float in the liquid phase.

FIG. 3 is a schematic cross-sectional view showing a state in which the filter device shown in FIG. 1 is cleaning contaminants.

Referring to FIG. 3, in order to clean the filter device 100 according to an embodiment of the present invention, the second tube 130 is clogged and the third tube 140 is filled with a liquid for cleaning the filter device 100 Respectively. The liquid flowing from the third pipe 140 is discharged to the first pipe 120.

A liquid for washing flows into the interior of the filter device 100 through the third pipe 140 (a). The pressure of the liquid flowing through the third pipe 140 causes the cleaning balls 150 to float inside the disc assembly 160 (b). The wash balls 150 hit the disk assembly 160 to vibrate the disk assembly 160. This vibration causes the contaminants attached to the disc assembly 160 to separate from the disc assembly 160. The separated contaminants float in the liquid phase, and the liquid is discharged to the outside of the body 110 through the first tube 120 (c).

The cleaning ball 150 may be formed of aluminum so that contaminants do not propagate. The cleaning ball 150 hits the disc assembly 160 and contaminants from the disc assembly 160 can be attached to the cleaning ball 150. [ At this time, the cleaning ball 150 may be formed of aluminum or a metal material in which other germs are difficult to propagate so that contaminants adhered to the cleaning ball 150 do not propagate.

As described above, the cleaning ball 150 is connected to the second pipe 130 and the third pipe 140 at the boundary between the second and third pipes 130 and 140 and the hollow spaces 112 and 114, A blocking net 170 may be provided that is not discharged to the outside. In particular, when the disc assembly 160 is formed so as not to block the second tube 130, that is, when the disc assembly 160 is not formed to cover the second tube 130, A blocking screen 170 may be provided so that the display screen 150 is not discharged.

Meanwhile, as described above, the disc assembly 160 may not be formed in the inner hollow portion 112. The inner hollow portion 112 may be filled with a material such as a liquid, solid or gel-like filtration material.

4 is a schematic perspective view showing a part of a disk assembly inserted into the filter device shown in Fig.

The inner hollow portion of the filter device according to an embodiment of the present invention may include a disk assembly 160 in which a plurality of disks 160 are formed in which a hollow is formed to allow liquid to pass therethrough and contaminants to be filtered. .

4, the disc assembly 160 includes a disc guide 166 for guiding the disc 161, an upper cap 165 for preventing the disc 161 from separating from the disc guide 166, Cap. More specifically, the disk guide 166 may be formed in a cylindrical shape, and the upper and lower portions and sides of the disk guide 166 may be opened, that is, may be formed with a plurality of holes or a skeleton so that the liquid can move smoothly. Here, the cleaning ball may hit the disk 161 directly or may hit the disk guide 166 to vibrate the disk assembly 160.

The upper and lower caps 165 and 165 mounted on the upper and lower sides of the disk guide 166 are respectively provided with packing to close the upper and lower walls of the filter device to seal the inside of the filter device. The disk 161 to be mounted on the outer circumferential surface of the disk guide 166 is manufactured in the form of a plate-shaped donut, and is manufactured by stacking a plurality of disks.

Generally, the filter device having the disk is configured as described above to filter the liquid. The principle is that the liquid passes through the multilayered disk 165 to filter sand or solid matter. The disks 161 are laminated so that fine holes are formed by mutual engagement of the filtration protrusions, and the liquid passes through the fine holes and the impurities are filtered.

The disc is generally injection-molded into a synthetic resin material in consideration of easiness of manufacture and price. The disc is made of polypropylene or polyethylene resin, which is a raw material of the disc of the present invention, has a water-activating action and excellent moldability, TOURMALINE, which prevents the oxidation of iron ions, is added in an amount of 10 to 40%, melted at 170 to 200 캜, and injected into an injection molding machine. When the content of toluminal is less than 10% by weight, the activity is lowered and it is not effective in preventing the oxidation of iron ions. When the content is more than 40% by weight, miscibility with the disk resin is poor, It is not preferable because it is easy to occur. In addition, the particle size of the tohmal powder blended at this time is poor in miscibility with the resin particles larger than 150 mesh, and the particles having a particle size smaller than 400 mesh are difficult to handle. The preferred particle size of the toe-dried powder is 250-350 mesh.

When the disc 161 is formed by adding tallmalin, the disc improves not only the filtering function but also the water quality of the water during the filtration process, prevents oxidation and prevents the filter device from being adhered to the filter device . In addition, since the torsmallow has a characteristic that the cleaning ability is more effectively exhibited when the pressure or impact is applied, the water pressure generated when the liquid passes through the fine holes of the stacked disk 161 naturally pressurizes the disk It improves ability.

Although the embodiments of the present invention have been described in detail with reference to the accompanying drawings, it is to be understood that the present invention is not limited to those embodiments and various changes and modifications may be made without departing from the scope of the present invention. .
