Description

Sediment separating device

The present invention relates to a sedimentation separator capable of separating solid suspended solids and the like from sedimentation salvaged in the settlement.

Typically, a sedimentation basin is provided for removing sediment which flows in according to the flow of sewage and wastewater.

Such settlement lands sediment contained in inflow water such as sewage and waste water, for example, soil, sand, and debris to attract the primary purification (physical purification) by dropping to the bottom of the settlement. As is known to those skilled in the art, the organic matter attached to the sediments provides a basis for causing severe odors and waterborne diseases as they corrode.

In order to solve this problem, conventionally, the sediment is lifted to the outside of the settlement and washed with washing water (clean water), and then the settlement is taken out to the landfill site.

It is apparent that such a conventional cleaning system simply sprays only the washing water onto the saliva to be lifted, so that odors are generated in the saliva where organic contaminants or solid suspended solids are less washed. May cause.

The present invention has been created to solve various problems to be caused in the above-described submersion separator.

The object of the present invention is to reliably lower the moisture content of the sediment to be discharged as well as to separate the sediment and solid suspension, for which the present invention comprises a conveyor. The conveyor lifts the sediment deposited on the sedimentation basin and carries it to the sedimentation tank according to the present invention, which extends the length of the end of the conveyor to accelerate the dropping speed of the sedimentation when the sediment transported by the conveyor falls into the sedimentation basin. Unlike the direction, it is arranged to be inclined downward.

In addition, the present invention further includes a double inclined plate at a position where the immersion guided through the conveyor end that is inclined downward so as to efficiently separate the sinter and the solid suspended matter flows into the immersion cleaning tank. The present invention is directed to the distal end of the downward inclined conveyor is passed between a plurality of double inclined plates arranged in parallel and flowed between a plurality of double inclined plates just before the accelerated settling flows into the settling bath, while hitting the double inclined plate The impact can separate the solid suspension from the settling. In addition, the accelerated sedimentation is slowed down by hitting the double sloping plate to slowly sink in the sedimentation bath.

In addition, the present invention includes an underwater stirring mixer for supplying air in the immersion cleaning tank. This agitator mixer is equipped with an diffuser to continuously supply external air to the rinsing water contained in the settling bath. The air supplied in this way (micro-strength gun) adheres to the solid suspended solids, and the suspended solids do not settle down and maintain a constant level in the immersion cleaning tank, resulting in floating on the stored washing water surface. These floating floats are discharged to the by-pass of the settling tank. Optionally, this diffuser can be further attached with means such as an air pump to force air into the rinsing bath.

The present invention allows the transfer of a gas, which is a physical phenomenon in which certain gas molecules are exchanged at the interface between a gas and a liquid, by means of the above-described underwater stirring mixer. The gas commonly used in water treatment is air, and the liquid is water. The artificial contact between air and washing water is called aeration, and the purpose of this aeration is to remove or degas the bad gas dissolved in water or to change the bad substance into a better form. In order to maintain a constant concentration of the gas required to promote a certain reaction, such as an oxidation reaction, the supersaturated dissolved oxygen in water can be released into the atmosphere to sufficiently remove the odor component.

In addition, the present invention causes the flow and disturbance of the washing water in an agitating mixer to allow the sag to be sufficiently brought into contact with the washing water. The increased water content settles to the bottom of the settling tank. In addition, the washing water stored in the sink cleaning tank does not directly fall onto the inclined screw conveyor that carries the needle from the needle cleaning tank to the needle separator, so that the free fall rate is lowered by passing the washing water. Reduces the amount of impact on inclined screw conveyors.

The sedimentation flowing into the sedimentation separator in the inclined screw conveyor is carried out to the landfill by reducing the water content through the sedimentation separator of the present invention.

According to the description of the present invention, the present invention provides an effective and easy separation of solid suspended matter or contaminants from sedimentation through processes such as collision, degassing and aeration.

In addition, the present invention has improved durability to significantly reduce the wear of constituent members due to friction with sedimentation in all processes.

The present invention provides the effect of lowering the moisture content of the sediment to be finally taken out to the landfill.

The present invention will now be described in more detail with reference to the accompanying drawings.

The present invention preferentially increases the water content of the sediment lifted from the sedimentation basin to increase the fluidity of the sedimentation, thereby facilitating separation from the solid suspended solids, and finally by lowering the water content of the sedimentation through the dehydration process, it can be taken out to the landfill.

In order to achieve the object of the present invention, the present invention is a conveyor (100); Sedimentary cleaning tank 200; Inclined screw conveyor 300; And a sedimentation separator 400. In addition, the low moisture content sedimentation from the sedimentation separator 400 is forcibly carried to the storage hopper via the air conditioner (500).

The conveyor 100 of the present invention guides up to the immersion cleaning tank 200 after lifting the erosion deposited on the clarification paper. Preferably, before being spread on the conveyor 100, the contaminants mixed with the sedimentation are filtered through the screen for removing the contaminants so as not to flow into the salivary cleaning tank through the screen for removing the contaminants (not shown).

The present invention is provided with a separate component to separate solid suspended solids that have not been removed with the screen for removing the contaminants from sedimentation.

First, the conveyor 100 of this invention is equipped with the terminal part 110 in which one part is inclined downward. In other words, the conveyor 100 is generally elongated. One end of the conveyor 100 is disposed on the scavenger and the other end is disposed on the scavenger rinse tank 200, in particular, the conveyor extends to the scavenger rinse tank 200. The distal end 110 of the 100 is arranged inclined downward unlike the overall length of the conveyor 100.

The lower conveyor end 110 serves to further increase the drop speed before dropping the saliva lifted from the settling paper into the settling cleaning tank 200. This rolls down along the distal inclined downward with the conveying speed of the settled and transported seated on the conveyor 100 to further accelerate the falling rate of the settling.

The present invention includes an immersion cleaning tank (200) which not only improves fluidity while washing the immersion carried by the conveyor (100) with washing water, but also helps contact with air. The immersion cleaning tank 200 includes a washing water supply pipe 210, a bypass pipe 220, an underwater stirring mixer 230, and a plurality of double inclined plates 240.

The immersion cleaning tank 200 includes a washing water supply pipe 210 for supplying washing water to maintain a predetermined water level therein. When the inflow of the sedimentation increases, since the washing water in the needle washing tank 200 must maintain a constant water level, a part of the washing water is discharged to the bypass pipe 220. Preferably, the installation height of the bypass tube 220 is higher than or equal to the washing water level.

A plurality of double inclined plates 240 are disposed at the dropping point where the sediment is introduced, without directly falling into the sedimentation cleaning tank 200 filled with the washing water. As shown, the double inclined plates 240 are spaced apart from each other in parallel. Sedimentation accelerated to the distal end of the conveyor 100 is dropped into the gap between the parallel inclined double inclined plate 240 collides with the double inclined plate 240 (see FIG. 3). While the acupuncture collides with the double inclined plate 240, the impact causes the solid suspended solids attached to the acupuncture to fall off.

Preferably, the double inclined plate 240 is installed on the surface of the washing water so that the impact amount can be further applied while the sediment falls to gravity without being affected by the buoyancy of the washing water. If the double inclined plate 240 is immersed in the washing water, the impact amount will be reduced between the sedimentation and the double inclined plate.

In addition, the double inclined plate 240 does not fall directly on the inclined screw conveyor 300 provided on the lower side of the immersion cleaning tank 200 while maximizing the impact effect wear on the inclined screw conveyor 300 It can significantly reduce the service life.

As described above, the needle cleaning bath 200 of the present invention includes an underwater stirring mixer 230. As shown in FIG. 2, the underwater stirring mixer 230 includes a motor M for driving the rotating shaft 231, a porous plate 232 provided below the rotating shaft 231, and an diffuser for dispersing air into the water. 233 is provided. The diffuser 233 is a hollow tube made of an L-shape. The diffuser 233 is a hollow tube, and has an inlet 233 ′ through which air is introduced and an outlet 233 ″ through which air is discharged, and is fixed to the rotating shaft 231 and the porous plate 232.

The underwater stirring mixer 230 rotates the porous plate 232 and the diffuser tube 233 fixed to the rotating shaft 231 by the driving of the motor M. FIG. In particular, the inlet 233 'of the diffuser 233 is positioned higher than the surface of the wash water and its outlet 233 "is located in the water. The rotation of the underwater stirring mixer 230 causes air to flow to the inlet 233'. Sucked in, this intake air disperses air into the wash water through outlet 233 ". In the rotational drive of the motor M, the diffuser 233 having a predetermined thickness is rotated to stir the washing water and the dropped needles to mix these substances. With this agitation, the washing water washes away the solid suspended matter adhering to the sedimentation, and also brings air into contact with the organic contaminants to cause deaeration or aeration, as well as increase the water content of the sedimentation to improve fluidity.

The porous plate 232 has a plurality of through holes 234 on its flat surface. The through hole 234 helps the flow of the washing water and the disturbance thereof by the rotation of the underwater stirring mixer 230.

In order to accelerate the flow of the washing water into the through hole 234, the through hole 234 may be formed by drilling the porous plate 232 in a cylindrical shape, a truncated cone shape, or a funnel shape. The shape of the through hole is not shown in detail in the accompanying drawings.

This sufficiently washed sediment is seated on the inclined screw conveyor 300 located in the bottom portion of the sedimentary washing tank 200 by the gravity of its own weight.

The inclined screw conveyor 300 extends from the bottom of the immersion cleaning tank 200 to the immersion separator 400, as is well known to those skilled in the art, so that the immersion cleaning tank 200 has a high moisture content. Lift and transport to the sedimentation separator (400). The inclined screw conveyor 300 may be smoothly pulled up to the sedimentation separator 400 through the fluidity of the high sedimentation.

Referring to Figure 4, the sedimentation separator 400 according to the present invention is installed in the cyclone tube 420 on top of the fluid communication with the main body 410, the first screw 430 and the second screw 440 The partition wall 450 is formed between the upper and lower sides of the partition wall 450, and the opening 460 is formed at the lower end of the partition wall 450 so that the needles lowered by the first screw 430 may move toward the second screw 440. Such a sedimentation separator 400 is described in more detail in the applicant's Republic of Korea Utility Model Registration No. 20-0350258, which is incorporated herein by reference in its part.

For reference, the sedimentation separator 400 primarily separates water and sedimentation from the cyclone tube 420 by using the cyclone principle, and when the sedimentation separated from the cyclone tube 420 falls, the first screw 430. Pushed down to the lower side, the needle to be stagnant on the lower side of the first screw 430 is discharged to the second screw 440 side through the opening 460. Then, the sedimentation is to separate and discharge the sedimentation to the discharge pipe 470 located at a position higher than the water level along the second screw 440.

In particular, the rotary plate 480 is further provided on the axis of rotation of the first screw 430 to separate the sediment (sand) and the organic material introduced from the cyclone tube 420 at a high speed. The rotating plate 480 is composed of a pusher plate 481, a porous plate 483, and a through hole 482 formed in the porous plate 483. The rotating plate 480 is preferably positioned below the level of the washing water to be filled in the main body 410 in order to increase the washing power between the washing water and the settling.

The rotating plate 480 is illustrated in more detail in the circular arc part of FIG. 4, and includes a porous plate 483 disposed at right angles to the rotation axis of the first screw 430, and a plurality of through holes formed in the porous plate 483. 482. Subsequently, the porous plate 483 disposed on the rotational axis of the first screw 430 rotates. In this rotation, the washing water filled in the body 410 of the immersion separator 400 and the immersion to be introduced from the cyclone tube 420 are rotated at the same time, so that the sintering is washed with the washing water to maintain a cleaner state. do. To more effectively achieve contact with the wash water, the rotary plate 480 places a plurality of push plates 481 perpendicular to the porous plate 483. Optionally, the pusher plate 481 may be evenly distributed or radially disposed on the porous plate 483.

As the rotating plate 480 disposed on the rotating shaft rotates, the washing water is more strongly rotated by means of the plurality of vertically disposed plate 481 arranged vertically. The swirling washing water can wash away the sewage contained in the sedimentation in a short time.

Optionally, the upper portion of the pusher plate 481 is further provided with an inclined plate 484 inclined at a predetermined angle with respect to the pusher plate. In FIG. 4, the pusher plate 481 is disposed perpendicular to the rotary plate 480, but the pusher plate 481 may be disposed to be inclined at a predetermined angle directly on the rotary plate without having an inclined plate separately.

The washed acupuncture is seated on the first screw 430 through a gap between the through hole 482 or the rotating plate 480 and the main body 410 to be lowered below the main body 410. Of course, the cleaning force may be improved by doubling the flow effect of the washing water to the through hole 482 through the rotation of the rotating plate 481.

In addition, since the rotating plate 480 provided in the sedimentation separator 400 of the present invention rapidly processes the separation process between the sedimentation and the organic matter, the load on the lower side of the first screw 430 may be significantly reduced.

As such, the sedimentation separator 400 not only helps to cleanse and separate the impurities from the sediment, but also significantly lowers the water content of the sedimentation to be carried out to the landfill.

This cleanly separated sediment may be forcibly transported to the storage hopper through the air conditioner 500, and the sediment which was temporarily stored in the storage hopper will be carried out to the landfill later.
