Water treatment device {WATER TREATMENT APPARATUS}

The present invention relates to a water treatment apparatus, and more particularly, it is possible to process all of the removal of contaminants, washing and lifting of scum, removal of scum, and can effectively remove fine suspended solids such as oil (membrane) floating on the water surface, The present invention relates to a water treatment device having excellent durability and low installation cost and construction cost.

With the increase of the population, as the industry develops, the amount of waste water discharged from homes and factories is increasing.

These sewage and waste waters are called sewage along with rainwater, and these sewage contain a large amount of pollutants, and when discharged as it is, the water quality is greatly deteriorated. do.

On the other hand, various contaminants are introduced into the water treatment facility together with the inflow water in various pumping stations such as intake pumping stations or relay pumping stations. If the contaminants contained in the inflowing water are not removed properly, the pumps or machinery installed in the pumping station may be damaged. In addition, the transition to the next process is not carried out, which causes the entire facility to become useless.

For this reason, in most water treatment facilities, a sedimentation device or a settlement is provided between a conduit and a sedimentation basin, and the water sinks and plastic bottles or branches that sink in water like small gravel or sand contained in the inflow water. Likewise, the floating debris is removed by physical means.

Conventional needle bed is a structure that removes and removes contaminants using a perforated screen or a wedge drum-type screen, and then lifts and removes them with a screw, collects the sands with a horizontal screw conveyor, and lifts and removes the sands with an inclined screw conveyor. Consists of

However, according to such a structure, by using a plate having a plurality of holes as a screen for removing impurities and employing a brush as a means for cleaning the screen, it is impossible to completely remove the impurities caught in the holes (or meshes) of the screen. There was a disadvantage that can not fully function.

In addition, conventionally, when removing the sedimentation (sediment) deposited on the bottom of the sedimentation tank, by using a combination of the horizontal screw conveyor for feeding and the inclined screw conveyor for saliva salvage, the power to drive the needle bed or the needle bed It is consumed a lot, and the electrical field (length, height, width, etc.) of the machine is increased, not only increase the facility cost, construction cost and civil engineering cost, but also had a lot of difficulties in maintaining and managing various machinery and pumps.

In addition, since the conventional immersion apparatus is not provided with a scum removing means, the scum and fine flotation are passed to the rear end to decrease the processing efficiency, and to remove floating matters such as oil or soap bubbles, the scum removal means separately. Adopting a scraper or scraper was uneconomical and complicated in structure.

The present invention is to solve and solve the problems caused by the conventional water treatment apparatus as described above,

The inclined plate 600 has a higher position of the outlet end than the inlet end, and the guide wall 610 gradually goes from the inlet end to the outlet end by the guide wall 610 formed so as to gradually narrow on both sides of the inclined plate 600. It is formed so that the space between them narrows. As the second screen unit 200 is installed on the inclined plate 600 arranged as described above, scum flowing through the inclined plate 600 may be efficiently removed.

At this time, the inclination adjusting means 620 is installed to adjust the degree of inclination of the second screen portion 200 and the chain 400 described below according to the angle of the inclined plate 600. The inclination adjusting means 620 adjusts the angle of the guide rail 202 formed on the second screen portion 200 and the angle of the scratching portion 500 installed on the chain 400 rotating in an infinite orbit. Accordingly, the scratches 500 may be seated in the correct position, the movement of the scratches 500 may be smoothly guided, and the gap between the second rakes 530 may be maintained to efficiently remove scum. Will be. The inclination adjustment means 620 may be configured to enable both the inclination of the inclination plate 600 as well as the inclination of the second screen part 200 and the chain 400.

In addition, the water treatment device 10 according to an embodiment of the present invention effectively removes scum and maintains a constant level of the immersion tank SP, in order to maintain a constant water level in the rear of the second screen part 200. 16 and the discharge tank 18 is formed.

The immersion hopper 300 is formed at the lower portion of the first screen portion 100, and is included in the inflow water, and the sintered deposits, ie, sand or stone fragments, which are settled in the immersion tank SP, are described below. Are components that are gathered by

Chain 400 is composed of a pair of endless tracks are installed inside the immersion tank (SP), it is operated by the driving force generated by the motor 410. The chain 400 is connected to the sprocket wheel 420 provided in the upper end of the first screen portion 100 or inside the needle tank SP using a conventional fixing means such as a bracket. Here, the motor 410 and the sprocket wheel 420 may be directly connected, but when connected using a chain 400 or a belt, it is possible to arbitrarily adjust the moving speed of the chain 400.

The scratching unit 500 is installed to cross the pair of chains 400 at regular intervals and is operated when the chain 400 rotates, and the scraper 510 and the first rake 520 and the second rake 530. It is configured to include). One side of the scratching unit 500, that is, the scraper 510 is in contact with the bottom of the immersion tank (SP) to move the sedimentation settled in the immersion tank (SP) to the immersion hopper (300) of the scratching unit 500 The other side, that is, the first and second rakes 520 and 530 are in contact with the first and second screen portions 100 and 200 to separate the scum and scum.

The first rake 520 is operated to separate the contaminants caught in the first screen portion 100, for this part is formed in an uneven (凹凸) shape.

The second rake 530 is the end portion of the first rake 520, that is, the end of the convex-concave shape of the first rake 520, the concave-convex shape is a contaminant caught in the first screen portion 100. And the scum pinched by the second screen unit 200 is separated.

The scratching part 500 is operated in a state in which it is in close contact with the bottom of the immersion tank (SP) and the first and second screen parts (100, 200) to increase the efficiency as well as to restore the original shape after the work It is preferable to form using a rubber or non-metal material excellent in elasticity so that the same work effect can be exhibited at the time of work. Meanwhile, although the scraper 510 and the first and second rakes 520 and 530 constituting the scratching part 500 are shown as separate bodies in the illustrated drawing, they may be configured as one body.

Hereinafter, a water treatment apparatus according to an embodiment of the present invention having such a configuration will be described in detail with reference to the accompanying drawings.

7 to 10 are enlarged views of A, B, C, and D shown in FIG. 2.

Waste water, that is, inflow water containing various contaminants, is introduced through the inlet 12 formed in the water treatment device 10, and the first screen unit 100 installed at the rear of the inlet 12, for example, For example, bar screens are used to filter out debris.

Then, the sedimentation (sand or stone fragments) included in the inflow water introduced through the inlet 12 is settled at the bottom of the sedimentation tank SP.

On the other hand, the pair of chain 400 is rotated to the infinite track by the driving force of the motor 410.

At this time, the first and second rakes 520 and 530 of the scraping part 500 installed in the chain 400 while the chain 400 is rotated as shown in FIG. 9. Raked up by

The first and second rakes 520 and 530 are forcibly scraped out of the contaminants or sediments caught between the bars of the first screen unit 100 to filter out contaminants. In this case, when the bar shape of the first screen unit 100 is formed in a wedge shape (triangular bar), separation of contaminants caught between the bars can be made more smoothly.

Complexes separated from the first screen portion 100 are lifted upwards. At this time, the scraper 510 adjacent to the first and second rakes 520 and 530 serves to support the separated impurities.

The contaminant separated and lifted in this way is passed through the sprocket wheel 420 installed at the highest position of the first screen unit 100, and the contaminant container located outside the water treatment apparatus 10 through the duct-type contaminant discharge port 110. Discharged to 120.

In addition, the scum that is not filtered out of the first screen unit 100 among the pollutants flowing in with the influent flows inflow water while the scratching unit 500 installed in the chain 400 rotating in an orbit moves over the surface of the water. The second screen portion 200 is filtered to be moved toward the inclined plate 600, and the second screen unit 200 is installed on the inclined plate 600, so that the inflow water is secondarily filtered through the second plate unit 200. 2 The scum will be pinched on the screen.

On the other hand, the scratching part 500 is a guide screen 202 formed in the second screen portion 200 is inserted into the recess of the concave-convex shape of the first rake 520, the second screen stably without flowing It is seated on the part 200 and moves in the state which maintained the space | interval of the 2nd rake 530. If the scratching part 500 cannot be stably seated on the second screen part 200, the scum can not be removed efficiently, and thus the inclination of the second screen part 200 is adjusted using the inclination adjusting means 620. The inclination of the second screen unit 200 may be adjusted to the angle of the inclination plate 600. When adjusting the inclination of the second screen portion 200 or the inclination of the inclined plate 600, or the degree of inclination of the second screen portion 200 and the inclined plate 600, the inclination of the chain 400 is also inclined adjustment means ( 620 may be used to adjust the inclination. If the degree of inclination of the chain 400 does not match the inclination of the second screen unit 200 or the inclined plate 600, the scratching unit 500 moving in accordance with the rotation of the chain 400 is the second screen unit 200. It is difficult to settle in stably. 8 illustrates a state in which the degree of inclination of the chain 400 is changed by the inclination adjusting means 620.

As the scratch part 500 is seated on the guide rail 202 and moved, the second rake 530 is separated from the scum caught by the second screen part 200 as shown in FIG. 10. At this time, the inclined plate 600 has a higher position of the outlet end than the inlet end, and is formed to narrow gradually between the guide wall 610 through the scum discharge port 210 in the state where the scum is densely packed. Discharged to the container 220. Scum container 220 is preferably made of a mesh to facilitate the dehydration treatment.

The first and second rakes 520 and 530 are separated from the second screen unit 200 while passing through the sprocket wheel 420 installed at the bottom side of the immersion tank SP. The position of the scraper 510 is reversed as shown in FIG. 7. Thus, the sedimentation settled on the bottom of the sedimentation tank (SP) is scraper 510 is contacted to the bottom of the sedimentation tank (SP) while being scraped and collected in the sedimentation hopper (300).

The collected sedimentation is cleaned by the cleaning air injected from the blower 302a through the nozzle 302 provided in the inside of the needle hopper 300. As such, the acupuncture may be cleaned using the cleaning air. In addition, the acupuncture may be cleaned by receiving a washing water from a washing water supply device (not shown), or washing the acupuncture by using both the washing air and the washing water. have.

At this time, the lower width is formed in the 'V' shape of the narrower than the upper width (SP) lower portion of the trapezoidal trappings of the trapezoidal trapping type installed by installing a trapezoidal prevention plate 304, the settling hopper during the cleaning of the needle It is good to prevent the departure from 300.

The cleaned sediment is lifted using the sedimentation discharge conveyor 310 having a lower end portion partially inserted into the sedimentation hopper 300, and discharged to the sedimentation container 330 through the sedimentation discharge port 320. Here, although the sedimentation discharge conveyor 310 may be installed in a horizontal form on the ground, it is preferable to install at an angle so that the dehydration action occurs during saliva salvage.

Inflow water from which various contaminants have been removed through this process is discharged to the next treatment process through the outlet 14, and when cleaning or maintaining the sedimentation tank SP, the drain valve 306 installed in the sedimentation hopper 300 is opened. Open to discharge the influent remaining in the settling tank (SP).

On the other hand, the scratching portion 500 passing through the immersion hopper 300 is the position of the first and second rakes 520, 530 and the scraper 510 while passing through the sprocket wheel 420 installed on the immersion hopper 300 Inverted as shown in FIG. 8, the contaminants and scums caught in the first and second screen units 100 and 200 may be removed.

On the other hand, in the present specification, the scraper 510 has been shown to be formed in the form of a plate, but instead of the scraper 510 of this shape using a bucket (Bucket) in contact with the bottom of the immersion tank and can be stored in the form, It may be configured to discharge the sediment raised by the bucket to the contaminant container 120 through the contaminant discharge port 110.

As described above, the water treatment device 10 according to an embodiment of the present invention, as well as a function of removing scratches and scum from the scratches 500 installed across a pair of chains, the sedimentation tank SP By the function of transferring the sedimentation settled at the bottom of the to the immersion hopper 300, it is possible to omit the expensive needle feeding conveyor used in the conventional water treatment apparatus can be economical as well as has the advantage of simplifying the structure. .

Thus, those skilled in the art will appreciate that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
