Description

Filter {filter}

The present invention relates to a filter equipped with a bottom brush to scrape the bottom plate of the housing.

Conventionally, the rotating shaft of the brush is manually rotated or driven by external power such as a gear motor to scrape off and remove foreign substances. In the case of manual cleaning, there is an inconvenience of rotating the brush.

When the rotation axis of the brush is rotated by a separate motor, there is a high possibility of explosion by oil vapor or dust, and it is difficult to use in an area where power line supply is difficult.

As a conventional filter for solving this, it is proposed, for example in patent document 1,2.

As shown in Figs. 11 and 12, the aberration filter of Patent Document 1 mounts the aberration 19 to the rotational axis 6 'of the brush 5' and injects arranged in the rotational tangential direction of the aberration 19. Influent water injected into the tube (2) is filtered while rotating the aberration (19).

By the way, since the inflow water is injected into only one injection pipe 2, as long as the inflow water comes in, the inflow water flows into the filter tube 4 while rotating the aberration 9.

Therefore, since the aberration 19 performs a continuous operation, the brush 5 'continues to scratch the filter cylinder 4, so that friction occurs and the replacement cycle of the brush 5' is accelerated.

In addition, since the inflow water flows into only one of the injection pipes 2, the rotation speed of the aberration 19 can not be adjusted, and if the flow rate of the inflow water is large, the rotation shaft 6 ′ is forced by the large rotation speed or the brush 5. Increase the wear rate of '), can give a big impact on the aberration (19).

In addition, when the flow rate of the influent is small, the inflow rate may be low, and may not be able to rotate due to the pressure applied to the aberration 19.

On the other hand, in Patent Document 3, as shown in Fig. 13, the foreign matter removing unit 19 and the foreign matter suction hole 12 is a pie shape, except for the portion where the foreign matter removing unit 19 and the foreign matter suction hole 12 meet. Since there is no suction flow of foreign matter (that is, dead zone formation), the foreign matter removal efficiency is very low because it does not uniformly suck foreign matter over the entire height of the filter barrel 11.

In addition, when foreign matter adheres to or deposits on the bottom plate of the filtration main body 1, the drain valve is opened and discharged, which is not enough.

Patent Document 1: Korea Utility Model Publication No. 1995-0001300 Patent Document 2: Korean Utility Model Publication No. 20-0121460 Patent Document 3: Korean Patent Publication No. 1996-0008252

The debris removal unit includes a suction tube formed with a side suction port and a lower surface suction port for suctioning the foreign substance, a discharge connection tube formed at the suction tube to discharge foreign substances to the foreign substance discharge tube, and a filter cylinder brush installed at the side of the suction tube; It is preferable to include a bottom brush installed on the lower surface side of the suction tube.

The filter of Claim 3 of this invention,

Preferably, the suction cylinder has a vertical suction cylinder having a narrow upper portion and a wide cross section at a lower portion thereof, and a 'L' shape which is a horizontal discharge connection tube installed at the lower portion of the suction cylinder.

According to the configuration of claim 3, the cross-sectional area is set differently according to the height of the suction tube to eliminate dead zones in which the suction is stagnant, so that uniform suction is possible through the entire height of the filter barrel.

The filter of Claim 4 of this invention,

The discharge connection pipe is connected to the discharge coupler, it is preferable that the discharge coupler is coupled to the rotating shaft while rotatably mounted to the foreign substance discharge pipe.

As is apparent from the above description, the present embodiment has the following effects.

The bottom brush which scrapes off the lower plate of the housing is combined with the suction cylinder, which greatly increases the interval and time of disassembly and cleaning of the housing by removing floating matters accumulated on or attached to the sole plate, which is very efficient in terms of maintenance.

The cross-sectional area is different depending on the height of the suction cylinder, and the discharge connection pipe is disposed in the suction cylinder having the larger cross-sectional area, so that the foreign matter is uniformly flowed according to the height of the suction cylinder, thereby removing foreign substances through suction through the entire height of the filter cylinder.

Best Mode for Carrying Out the Invention Preferred embodiments of the present invention will be described below with reference to the accompanying drawings, where like reference numerals are used to designate like parts, and detailed description thereof will be omitted.

1 is a cross-sectional view showing a filter according to a preferred embodiment of the present invention.

As shown in FIG. 1, the filter of the present invention includes a housing 100, a filter barrel 200 mounted on the housing 100, a rotating shaft 300 rotatably supported by the housing 100, and a rotating shaft 300. Rotating together with a foreign material removal unit 300 for removing the foreign matter in the filter 200, the power transmission unit 500 for transmitting the rotational power to the rotating shaft 400.

The housing 100 includes a container body 110 including a side wall 111 and a bottom plate 113, and a cover 120 covering an upper surface of the container body 110. The cover 120 is provided with a valve for an air vent, a pressure gauge and a pressure switch, not shown.

One side of the side wall 111 is provided with an injection tube 130 through which the inflow water is injected, and an outlet tube 150 through which the filtered water is discharged is provided on the other side of the side wall 111.

The bottom plate 113 is provided with a foreign matter discharge pipe 140 for discharging the foreign matter filtered from the filter barrel 200. In addition, the foreign substance discharge pipe 140 is preferably provided with a foreign substance discharge valve 155. The bottom plate 113 is further provided with a discharge pipe 145, temporarily used to drain foreign matters inside the container body 110 for internal repair and the like.

Injection tube 130 is disposed above the upper end of the filter cylinder 200, the discharge pipe 150 is disposed on the side of the filter cylinder 200.

The filter tube 200 is a top and bottom open cylindrical tube, such as a screen filter, a metal or non-metal mesh or wedge wire, and the lower end of the filter cylinder 200 is seated in the seating groove 114 of the bottom plate 113. The upper end of the filter barrel 200 is fixed to the seating jaw 112 fixed to the inner circumferential surface of the side wall 111. Therefore, the filter barrel 200 is the inner cylinder, the container body 110 serves as an outer cylinder, the filtered water passing through the filter cylinder 200 is discharged through the water outlet pipe 150.

The upper portion of the rotary shaft 300 is supported by the cover 120 to be rotatable through the top bush 121, the lower portion of the rotary shaft 300 is coupled to the discharge coupler 470 described later.

The top of the rotating shaft 300 protrudes from the upper surface of the cover 120, the protruding top is formed with a polygonal head 310 that can be used to fit the handle (not shown).

In addition, it is preferable that the viewing window 330 is installed in the polygonal head 310 for sealing.

The present invention enables a closed structure when viewed from the outside. In particular, when rotating the rotating shaft 300 using the aberration 510 to be described later it is impossible to determine whether the rotating shaft 300 is rotated from the outside. The polygonal head 310 and the see-through window 330 make it possible to check whether the rotation shaft 300 is rotated from the outside.

In addition, the polygonal head 310 may simply grasp the rotation of the rotary shaft 300, and the difference in flow rate between the dry season and the flooding period, such as for agriculture, is easy to introduce foreign matter, or due to the rapid increase of foreign matter due to other circumstances. When attached to a large number of foreign substances in the filter barrel 200, the rotation of the aberration 510 becomes difficult. At this time, instead of disassembling and maintaining the filter, dismantling only the sight glass 330 and inserting a handle (not shown) in the exposed polygonal head 310 and forcibly rotating the rotating shaft 300, foreign matter removal unit 400 Opening the foreign matter discharge pipe 140 (simultaneous operation of the drain valve, if necessary) while rotating, it is possible to easily emergency measures and maintenance without disassembly and cleaning.

The foreign material removing unit 400 includes a suction cylinder 410 and a brush 440 and 450.

As shown in FIGS. 1 and 3, the suction cylinder 410 includes a suction cylinder 420 in which suction ports 421 and 423 for suctioning foreign substances are formed, and a foreign substance discharge pipe 140 for foreign substances in the suction cylinder 420. Consists of the discharge connection pipe 430 to discharge).

In particular, the suction cylinder 410 of the present embodiment is a vertical suction cylinder 420 having a different cross-sectional area depending on the height, the discharge connection pipe 430 horizontal to the vertical suction cylinder 420 of the larger cross-sectional area 'L' It is shaped like a child.

Therefore, when the filter barrel brush 440 scrapes the filter barrel 200, foreign substances from the top to the bottom of the filter barrel 200 are uniformly introduced into the suction tube 420 from the side suction port 421 through the entire height of the suction tube 420. As a suction is possible, foreign matter removal efficiency is very high by eliminating dead zones (non-flow sections) that are not suctioned through the entire height of the suction container 420. Side suction port 421 is preferably formed on the surface facing the filter barrel (200).

The discharge connection pipe 430 is connected to the discharge coupler 470.

The discharge coupler 470 is rotatably mounted to the foreign substance discharge pipe 140 in the state where the end bush 471 and the top bush 473 are started.

The lower side of the rotating shaft 300 is coupled to the upper portion of the discharge coupler 470.

Therefore, when the rotating shaft 300 rotates, the discharge coupler 470 and the suction cylinder 410 rotate along the circumference of the filter cylinder 200, and the foreign matter is the suction cylinder 410, the discharge coupler 470, the foreign substance discharge pipe ( Through 140).

The suction cylinder 410 is supported in the form of a cantilever in which the discharge connection pipe 430 is connected to the discharge coupler 470, and the support bar 425 fixed to the suction cylinder 420 is rotated to reinforce the strength of the rotation. It is preferable to be further installed at (300). Therefore, the support bar 425 and the discharge coupler 470 stably supports the suction tube 420 at the top and bottom.

Filter barrel brush 440 is a main brush to scrape off the foreign matter hanging on the filter barrel (200).

As shown in FIG. 4, the filter barrel brush 400 is installed at the support block 460 fixed to the front surface of the suction tube 420.

The support block 460 is a block having a cross sectional shape.

At this time, it is preferable that the filter barrel brush 440 is provided with an elastic member 480 to apply elasticity toward the filter barrel 200.

It is preferable that the metal filter net of the filter cylinder 200 is pushed so that the filter cylinder brush 400 comes into contact with the filter cylinder 200 because its radius is not always constant at the center of manufacturing.

The elastic member 480 is a spring 481 interposed between the one end 461 of the support block 460 and the flange 445 of the filter barrel brush 440. The filter barrel brush 440 is composed of a brush 441 and a brush support 443 supporting the brush 441, and a flange 445 is provided at the brush support 443.

Accordingly, one end 461 of the support block 460 and the flange 445 form a sheet at both ends of the spring 481.

In addition, as shown in Figure 4, it is preferable that the guide plate 490 is installed on the rear surface of the suction cylinder 420.

The guide plate 490 is inserted into the headless bolt 493 welded to the suction tube 420 and then fastened and fixed with the washer 495 and the nut 497.

The guide plate 490 forms a gap d between the filter cylinders 200, and when rotated in the direction of the arrow as shown in FIG. 4, the foreign substances scraping off the filter cylinders 200 are brushes 441, the filter cylinders 200, and the like. Staying between the guide plate 490, it is possible to prevent the scattering of foreign matter and reattachment to the filter barrel 200 to increase the suction efficiency to the side suction port (421).

In addition, it is preferable that the long hole 491 is formed in the guide plate 490 so that the space | interval d can be adjusted. The desired spacing d can be adjusted by the length of the long hole 491.

Therefore, when the foreign matter is large, it is preferable to widen the interval (d), and when the foreign matter is small, the interval (d) is narrowed to increase the suction efficiency of the foreign matter.

By doing so, it is possible to block foreign matters from being attached to the filter tank 200 again, thereby increasing the efficiency of the filter, and reducing the loss of the influent by discharging the foreign substances at a low flow rate, and also reducing the resource cost, energy saving, and the treatment cost of the discharged influent. It is an environmentally friendly device.

On the other hand, most of the filter is designed and manufactured with a focus on the removal of foreign matter adhering to the filter barrel 200, when the foreign matter is attached to or deposited on the bottom plate 114 of the housing 110, open the drain valve Discharging alone is not enough, and in most cases, it is usually disassembled and cleaned.

Therefore, in order to increase the period and time point of disassembly and cleaning, it is preferable that the bottom brush 450 is fixed to the lower surface of the suction tube 420.

Like the filter barrel brush 440, the bottom brush 450 is comprised by the brush 451 and the brush support body 453. As shown in FIG.

However, unlike the filter barrel brush 440, the bottom brush 450 does not need to apply elasticity toward the bottom plate 113 because the surface of the bottom plate 113 is almost flat and its height is fixed. to be.

A lower surface suction port 423 is formed on the lower surface of the suction tube 420, and suctions and discharges foreign matter suspended in the bottom plate 113 due to the pressure difference.

In addition, the bottom surface side guide plate (not shown) having the same function as the above-described side side guide plate 490 is added or the bottom brush of the bottom side of the side guide plate 490 is placed close to the bottom plate 113, the bottom brush It may be provided together with 450.

The bottom brush 450 is very usefully installed in the layout of the 'L' shaped suction cylinder 410 described above, thereby maintaining a compact device.

Meanwhile, as illustrated in FIG. 10, the suction cylinder 410 'has a vertical suction cylinder 420' having a narrow upper and lower portions and a wide cross section with a middle portion, and a horizontal portion provided at the middle portion of the suction cylinder 420 '. The same effect can be obtained even when the '접속' shape of the discharge connection pipe 430 '.

In addition, when the '┤' shaped suction cylinder 420 'is used, a separate suction cylinder may be made and a bottom brush may be installed.

The power transmission unit 500 is configured to transmit rotational power to the rotation shaft 300. In this embodiment, the aberration 510 coupled to the rotation shaft 300 and the driving injection pipe 530 for rotating the aberration 510 are rotated. ).

The aberration 510 includes a boss 511 coupled to the rotation shaft 300, a plurality of blades 513, and a connecting body 515 connecting each of the bosses 511 and the plurality of blades 513. Of course, the blade 513 itself may be directly coupled to the rotating shaft 300.

The driving injection pipe 530 is installed on the side wall 111 to more accurately face the rotational tangential direction of the blade 513 than the aberration 510.

The blade 513 may be attached by a plate-shaped pad, but may be implemented as a concave blade 513a or a convex blade 513b as shown in FIGS. 8 and 9.

This is advantageous by concentrating the pressure in the form of a concave converging influent when low influent flow rate (flow rate) or high rotational force is needed, and convex when large influent flow rate (flow rate) or low rotational force is needed. This is because the shape is advantageous by dispersing the pressure in the form of dissipating the influent.

In this embodiment, the injection tube 130 is at the same height as the drive injection tube 530.

That is, the injection tube 130 is at a height toward the aberration 510. Therefore, since the inflow water injected through the injection pipe 130 may impact the aberration 510, which may adversely affect the protection plate 135, it is preferable that the protection plate 135 is installed at the outlet side of the injection pipe 130.

The protection plate 135 is for preventing the inflow of the impact directly hit the aberration 510.

On the other hand, in order not to install the protective plate 135, it is preferable that the injection tube 130 is installed above or below the driving injection tube 530, and preferably below, because it is more effective in terms of aberration arbitrary rotation and aberration protection. .

In the case where the injection pipe 130 is installed below the driving injection pipe 530, both are advantageous when the diameter is small. This is because when the injection tube 130 has a large diameter, a dead space (space where inflow water does not directly enter the filter tube) is formed as long as it is out of the gap between the driving injection tube 530 and the upper end of the filter tube 200. This is inefficient compared to the aberration arbitrary rotation and aberration protection aspects.

In addition, if the injection tube 130 is disposed above the drive injection tube 530 to eliminate this dead space and to satisfy both the aberration arbitrary rotation and the aberration protection aspects, the housing should be higher.

Therefore, depending on the diameter and dead space, if the filtration capacity is relatively large, the diameter will be large and then the injection tube 130 is designed to be the same height as the drive injection tube 530, if the filtration capacity is small the diameter will be small Then, the injection pipe 130 may be designed to be installed between the drive injection pipe 530 and the top of the filter barrel 200.

On the other hand, since the injection pipe 130 and the drive injection pipe 530 is separately provided, it is necessary to selectively inject the influent, for this purpose, the inlet water selection valve 600 as shown in Figs. It is preferable to install.

The inflow means control valve 600 is controlled by placing the control valves 610 and 620 in the injection pipe 130 and the driving injection pipe 530 as shown in FIG. 5, or the three-way valve 630 at the branch point as shown in FIG. 6. ), The influent may be injected into the injection tube 130 or the driving injection tube 530.

On the other hand, it is preferable that the aberration rotation speed control unit 650 further controls the rotation speed of the aberration 510.

5 and 6, the aberration rotation speed control unit 650 is branched from the driving injection pipe 530 and installed in the branch pipe 651 and the branch pipe 651 connected to the injection pipe 130. It consists of a flow control valve 653 and the check valve 655. The check valve 655 prevents a backflow flowing into the driving injection pipe 530 from the injection pipe 130.

The aberration rotation speed control unit 650 has a large flow rate of the filter or a portion of the inflow water coming into the drive injection pipe 530 to reduce the rotational speed to the injection pipe 130, the amount of influent water transmitted to the aberration 510 How to control.

On the other hand, as shown in Figs. 1 and 2, when the aberration rotation speed control unit 650 'implements the outlet 651' of the drive injection pipe 530 as a streamlined nozzle, it is advantageous when the flow rate of the filter is small.

Similarly, even if the aberration rotation speed control unit 650 ″ is implemented as a nozzle 655 ″ mounted separately in the driving injection pipe 530, as shown in FIG. 7, it is advantageous when the flow rate of the filter is small.

As described above, although described with reference to a preferred embodiment of the present invention, the present invention can be variously modified or modified without departing from the spirit and scope of the present invention described in the claims Those skilled in the art will appreciate.

The present invention can be applied to any industrial automatic filter.
