Description

Sludge Collector with Maintenance Convenience and Improved Ability of Sludge Scraping}

The present invention relates to a sludge collection device installed in a gravity-type sedimentation basin in a biochemical water treatment process or a coagulation sedimentation basin in a physicochemical water treatment process, and smoothly collects sludge deposited on the floor and scum floating on the water surface to improve treatment performance. And a sludge collecting device to be removed.

The sludge collection device installed in a rectangular settling basin used for solid-liquid separation in a sewage treatment facility, water treatment facility, or production process collects the sludge deposited on the bottom of the settling basin in the sludge hopper while the flight mounted on the chain moves and pulls it out of the settling basin. In general, it is common to collect scum injured on the surface in parallel.

Since the land use efficiency is superior to that of the circular settling basin, the sludge collecting device installed in the commonly used rectangular settling basin is configured to circulate in the form of a caterpillar track. The sludge collection device installed in a circular settling basin is a structure in which an arm member rotates in a horizontal direction at the bottom of the settling basin, and is divided into a center driven type and a circumferential driven type. The sludge collecting device that circulates or rotates in this way collects the sludge settled on the bottom of the settling basin, collects it in a sludge hopper installed at one side or the center of the settling basin, and collects scum suspended on the surface of the settling basin.

Patent No. 10-1428801 discloses a sludge collecting device installed in such a conventional rectangular settling basin, and FIG. 1 is a conceptual diagram showing a general sludge collecting device installed in such a rectangular settling basin.

1 is a general sludge collecting device installed in a rectangular settling basin 101, and a driving unit 102, a driving sprocket wheel 103, a sprocket wheel 104 for supporting a chain, a flight 105 for collecting sludge, and a chain ( 106) shows a conventional caterpillar type sludge collecting device. The flight 105 is installed on the chain 106 rotating in the form of a caterpillar, and as the chain 106 is circulated by the driving unit 102, the flight 105 moves along the lower side of the settling basin and the settling basin 101 It is a structure to move the sludge deposited on the bottom and collect it in the sludge hopper 107 installed on one side of the settling basin 101.

Hereinafter, a sludge collection function corresponding to the first function of the sludge collection function and the scum collection function, which are two functions of a conventional sludge collection device, will be described.

As a main component of the sludge collection device, the flight 105 which directly acts on the settling sludge to transfer and collect the sludge acts to push the sludge settled on the bottom of the settling basin 101 and move it in the direction of the sludge hopper 107. Accordingly, the flight 105 is generally constructed of a rigid member having little elasticity and rigidity to withstand the applied load.

As such, the flight 105, which is composed of a rigid member with little elasticity, is in direct contact with the bottom surface of the sedimentation basin 101, which is mainly made of concrete, and strong resistance due to friction and severe wear occurs. It will be. Accordingly, the flight 105 is configured to move along the rail while sliding on a rail installed with an upper surface 15 to 20 mm higher than the floor surface so as not to directly contact the bottom surface of the settling basin 101. In addition, a shoe having a thickness of 12 to 15 mm is disposed on the flight 105 at a portion in contact with the rail to prevent abrasion and separation of the flight 105 and to reduce friction. Therefore, the flight 105 collects the sedimentation sludge from the top of 27 to 35 mm spaced apart from the bottom surface of the settling basin 101 by the sum of the thickness of the rail and the thickness of the shoe. Since sludge is collected at the top of the bottom surface, settled sludge is collected while remaining sludge with a thickness of 27 to 35 mm remains on the bottom surface. As described above, the sludge collecting device provided with the flight 105 composed of a rigid member of the conventional method leaves sludge of 27 to 35 mm thick on the bottom surface, so that the residual sludge is decayed, resulting in turbidity of treated water or sludge rising. Many of the same problems can arise.

Accordingly, the sludge collection flight 105 is provided with a plate made of a material such as rubber that has a thin thickness compared to its width and length and has a relatively large elasticity, and the flight 105 and the settling basin 101 are bottomed by the elastic plate. It also collects sludge by minimizing the gap with the cotton. The sludge collection device provided with an additional stretchable plate may improve sludge collection performance than when only the flight 105 of a hard material is provided. However, if there are grooves or small protrusions on the bottom of the sedimentation basin, not only does the elastic plate attached to the flight 105 properly remove the sludge stuck in the groove, and the flexible plate, which is an elastic material, is friction with the bottom surface. As a result, the wear progresses relatively quickly, and if the wear progresses, a gap is generated with the floor surface, and sludge collection is not smooth. In addition, even if the stretchable plate is worn, it is difficult to compensate for the worn part because it is difficult to easily compensate for the worn part because all the sedimentation basin submerged in water must be emptied and replaced. And it is difficult to repair.

In addition, in the sedimentation basin 101, scum including milk fat or floating sludge with air bubbles is suspended on the water surface, but if the scum is not properly collected and removed, it is discharged through the treated water, so the quality of treated water may deteriorate, and the sludge collection device It is common to use the scum collection function in parallel.

Hereinafter, a problem related to the scum collection function corresponding to the second function of a general caterpillar type sludge collection device installed in a rectangular settling pond will be described.

A significant load is imposed on the flight 105 while the flight 105 pushes the settled sludge. In order to distribute the load imposed on the unit flight 105, the number of flights 105 is increased, and the cross-sectional area in the front direction of each flight 105 is manufactured and installed in a relatively small area, and the lack of each flight 105 The cross-sectional area on the front side increases the installation location to meet the cumulative required area of the flight 105 required for sludge transfer. In the rectangular settling basin 101, the flight 105, which used to collect the sludge from the bottom, circulates and moves to the surface of the settling basin to collect scum floating on the surface.In the settling basin 101, the water level is also increased according to the change of the inflow load. Changes. Here, the front direction refers to the surface or direction that the flight pushes while directly in contact with the sludge. However, as described above, when the water level of the sedimentation basin rises due to an increase in flow load, the flights 105 having a relatively small upper and lower width do not properly collect scum from the water surface and contain bubbles, resulting in bulky scum. There is also a problem of leakage by overflowing from the front of the flight 105 to the rear.

The water surface of the settling basin 101, which is mainly constructed with reinforced concrete hardened by inputting concrete mortar into the mold, and the inner wall of the bottom side are difficult to be constructed in a straight line that is exactly parallel. If the inner walls of both sides of the settling basin do not form an accurate parallel straight line, a gap is generated between the inner wall of the settling basin 101 and both ends of the flight 105, which is a hard material, and the sludge and scum leak through the gap. There are also problems that cannot be collected and removed. In addition, even in a circular sedimentation basin mainly built with reinforced concrete, the inner wall surface does not form a true circle, so a gap is generated between the sludge scraper made of hard material and the inner wall of the sedimentation basin. Likewise, scum can leak backwards through the gap.

As such, conventional sludge collection devices do not smoothly collect the sludge deposited on the bottom of the settling basin and the scum floating on the water surface, so the sludge and scum are decayed and disassembled, resulting in the formation and leakage of fin flocs or the appearance of cake-shaped sludge. The treatment water becomes cloudy, such as the elution of dissolved contaminants, so improvement is required.

FIG. 2 relates to a sludge collecting device installed in a rectangular settling basin and operated in a caterpillar type for collecting sludge and scum 42.

The sludge collection device is installed in a sedimentation basin equipped with an inlet 3 and an outlet 4, and transmits the power of the driving unit 10 and the driving unit 10 to the chain 13 to generate rotational power. The drive sprocket wheel 11 for supporting the circulation track of the chain 13 to be kept constant, the chain 13 is mounted and supported so that the circulation track of the chain 13 is kept constant, and the movement of the chain 13 The support sprocket wheel 12 that rotates passively along the chain 13 is installed on the chain 13 to circulate in the form of a caterpillar, and when passing through the bottom of the settling basin, the sludge 40 deposited on the bottom of the settling basin 20 is collected. And when passing through the water surface of the settling basin, it is installed on a support such as a flight (15) that collects scum suspended on the water surface, and the chain 13 and the flight (15) circulating to repeat the bottom of the settling basin and the water surface. It is configured to include a skimming scraper 30 for collecting residual sludge remaining on the bottom surface of the settling basin 20 and scum floating on the surface of the settling basin while circulating. That is, the skimming scraper 30 is fixed to the sludge collecting device through the support.

Hereinafter, the configuration and operation of the sludge collecting device provided with the skimming scraper 30 of the present invention will be described in detail.

3A is a conceptual diagram showing the sludge collection function of the first embodiment of the skimming scraper provided in the sludge collecting apparatus according to the present invention.

The skimming scraper 30 of the first embodiment provided in the sludge collecting device according to the present invention is circulated by repeating the bottom and the water surface of the settling basin, and the remaining sludge 41 remaining on the bottom of the settling basin 20 and the surface of the settling basin A collection unit 31 that collects the floating scum 42, and is mounted on the chain 13 and acts on the collection unit 31 so that the inclination angle θ of the collection unit 31 is inclined or restored to its original shape. It comprises an elastic body 32 for applying an elastic restoring force so that the lower end of the collection part 31 is in close contact with the bottom surface of the settling basin 20.

The skimming scraper 30, which is mounted on the chain 13 and circulates, draws a normal h so that it is perpendicular to the settling basin bottom surface 20 at the mounting point A, and the mounting point A and the normal line become the settling basin bottom surface ( A gap occurs between point B, which intersects with 20). In addition, the collection unit 31 is configured to be longer than the interval so that the collection unit 31 includes a margin width, that is, a margin collection unit 31a. In this way, the elastic body 32 is deformed due to the difference in the upper and lower widths of the collection unit 31 and the distance between the mounting point and the floor surface, and the collection unit 31 is inclined while being inclined with the settling basin bottom surface 20. However, due to the friction between the lower end of the collecting unit 31 and the bottom surface of the settling basin 20, the collecting unit 31 is inclined backward, which is a side opposite to the direction in which the chain 13 rotates and moves. At this time, as the lower end of the collection part 31 is in close contact with the sedimentation basin bottom surface 20 by the elastic restoring force of the elastic body 32, the remaining sludge 41 left without the flight 15 being collected is scraped to the bottom to collect.

Since there is an empty gap between the lower end of the flight 15 and the bottom surface of the sedimentation basin as much as the thickness of the rail 18 and the shoe 17, the rail 18 described above even after the flight 15 collects the sediment sludge 40 The remaining sludge 41 equal to the total thickness t of the shoes 17 and the shoes 17 remains on the bottom surface 20 of the settling basin. The total length of the sum of the upper and lower widths of the collection part 31 and the upper and lower lengths of the elastic body 32 provided in the skimming scraper 30 of the first embodiment according to the present invention is the elastic body 32 is a chain ( It is configured to be longer than the vertical distance between the point (A) mounted on 13) and the intersection (B) of the bottom surface of the settling basin 20 and is provided with a spare collection part (31a). Therefore, the lower end of the collection part 31 not only directly contacts the bottom surface 20 of the settling basin, but also leaves a margin width. As the elastic body 32 is deformed by friction between the margin collection part 31a included in the collection part 31 and the sedimentation basin bottom surface 20, the collection part 31 is inclined to the rear, and the elastic body ( The lower end of the collection part 31 may be in close contact with the settling basin bottom surface 20 by the elastic restoring force of 32). In this way, the collection part 31 and the sedimentation basin bottom surface 20 are kept in close contact with each other by the elastic restoring force of the elastic body 32, and the flight 15 collects and reaches the floor without leaving the remaining sludge 41. Can be collected by scratching.

In a general sludge collecting device that is also configured by attaching a rubber plate to the flight 15, the lower end of the rubber plate is worn due to friction with the settling basin bottom surface 20, thereby creating a gap with the settling basin bottom surface 20. As such, when a gap occurs due to abrasion, the sludge collection is not smooth and needs to be replaced frequently, which is inconvenient for maintenance, and it is uneconomical because the operation rate decreases and the maintenance cost increases.

Accordingly, in the present invention, in preparation for abrasion, the sludge collection unit 31 includes a margin width, that is, a margin collection unit 31a, and the direction in which the collection unit 31 is upright, that is, a direction in which the inclination angle θ is increased. It is provided with an elastic body 32 to apply an elastic restoring force. Accordingly, even if the collecting part 31 is worn, the inclination angle θ of the collecting part 31 is gradually increased in response to the wear of the lower end of the collecting part 31 due to the elastic restoring force of the elastic body 32, As it is transformed into, the lower end of the collection unit 31 can be kept in close contact with the bottom surface of the settling basin. Therefore, even if the abrasion of the collection unit 31 is in progress, the lower end of the collection unit 31 and the sedimentation basin bottom surface 20 are in close contact with each other until the stage before the marginal collection unit 31a is all worn and a gap is generated. It will be able to maintain the condition continuously for a long time. As described above, the sludge collection device according to the present invention is provided with a spare collection section 31a in the sludge collection section 31, and scratches the remaining sludge 41 to the bottom surface until all the spare collection sections 31a are worn. Can be collected. Therefore, there is no need to replace or repair the collection unit 31 for a long time, maintenance is convenient, and operation rate and economic efficiency can be improved.

3B is a conceptual diagram showing the scum collection function of the first embodiment of the skimming scraper provided in the sludge collecting apparatus according to the present invention.

In sedimentation basins installed in sewage treatment facilities, scum containing foam, milk fat, or floating sludge floats on the water surface.If scum is not properly collected and removed, it is discharged through symbolic water, so the quality of treated water may deteriorate.

The skimming scraper 30 of the first embodiment is mounted on the chain 13 and circulates, while the collecting unit 31, which is inclined when passing through the settling basin bottom surface 20, passes through the water surface of the settling basin. As shown in 3b, by the elastic restoring force of the elastic body 32, the scum 42 is converted to an upright or close to upright state, and the scum 42 floating on the water surface of the settling basin is collected.

In the rectangular settling basin (1), the flight 15 that was collecting the sludge 40 from the bottom circulates and moves to the surface of the settling basin to collect the scum 42 floating on the surface.If the inflow load increases, the level of the settling basin is also It becomes higher. However, in order to distribute the unit load imposed on the flights 15 provided in the sludge collection device, the number of flights 15 is increased, and the cross-sectional area in the front direction of each flight 15 is manufactured and installed in a relatively small area. It is common. In this way, the cross-sectional area in the front direction of each flight 15 is limited, and the left and right widths of the flight 15 match the inner width of the settling basin, so the upper and lower widths of the flight 15 are inevitably composed of relatively small widths. to be. In this way, when the water level of the sedimentation basin rises due to an increase in the flow load, most of the flights 15 are immersed in water and the portion protruding above the water surface decreases. Accordingly, the scum 42 floating on the water surface cannot be properly collected, and the scum 42 may overflow to the rear of the flight 15. In particular, the scum 42, which is bulky and thickly floating on the surface of the water containing bubbles, increases the possibility of overflowing the flight 15.

The vertical width of the collection unit 31 provided in the sludge collection device according to the present invention or the sum of the vertical widths of the collection unit 31 and the elastic body 32 is basically the flight 15, the rail 18 ) And the upper and lower widths of the shoe 17 are wider than the sum of the upper and lower widths, and a margin collection part 31a is included that is a marginal width for abrasion. In addition, when the skimming scraper 30 passes through the water surface of the sedimentation basin, the inclination angle θ between the collecting part 31 and the water surface is in an upright state due to the elastic restoring force of the elastic body 32. It is converted and spreads all over the water surface to the marginal width of the collection unit 31. Accordingly, the upper end of the collection unit 31 (corresponding to the lower end in Fig. 3A passing through the bottom side) protrudes and moves above the water surface at a higher position than the upper end of the flight 15, so that it is in a bulky state such as bubbles. The scum 42 can also be collected smoothly.

The collection unit 31, the elastic body 32, and the hinges shown in Figs. 12 and 13 to be described later provided in the sludge collecting device according to the present invention are either side of the chain 13 or the flight 15 It can be installed on or on both sides. In addition, the hinge is installed on a member that connects a pair of chains 13 to each other, or on a bracket 39 extending from the chain 13 and the flight 15, or on a sludge collecting device for a circular settling basin. It may be installed on an arm member (19 in FIG. 18) or a bracket extending from the arm member 19 (39 in FIG. 19). Accordingly, in the specification of the present invention, the chain 13, the flight 15, the arm member 19 and the bracket 39, to which the collection part 31 and the elastic body 32 are connected and installed, are collectively referred to as a support body. I did.

3C is a side cross-sectional view showing the concept of a first embodiment of a skimming scraper provided in the sludge collecting apparatus according to the present invention.

3C is a cross-sectional view taken along the line D-D of FIG. 3A to aid in understanding the sludge collection device according to the present invention.

Almost all sedimentation basins are firmly built with reinforced concrete and are built by filling and curing concrete mortar in a mold with reinforced reinforcement inside it. Accordingly, it is a very difficult task to construct a reinforced concrete structure in parallel so that the distance between the inner walls of both sides of the rectangular settling basin 1 is consistent over the entire section. In addition, since it is difficult to construct a circular reinforced concrete structure so that the inner wall surface becomes a true circle even in the circular settling basin 2, deviations frequently occur.

However, when the collecting part 31 is made of a hard member with little elasticity and is in direct contact with the inner wall and floor of the settling basin that is firmly built with reinforced concrete, abrasion and breakage problems due to strong friction may occur. I can. In addition, when the collection unit 31 is composed of a hard member and a slight deviation is made based on the position closest to the wall so as not to directly contact the wall of the settling basin, sludge or scum ( 42) may also leak to the rear of both sides of the collection unit 31. Accordingly, in the present invention, both sides of the collection unit 31 are made of a material such as soft and elastic natural rubber, EPDM, soft PVC, polyurethane, etc., which relatively little friction and damage occurs even when contacting the reinforced concrete structure. Collection by selecting from among those molded in the form of plates, nets, brushes, etc., and configuring both sides of the collection unit 31 to adhere to the wall surface longer than the widest inner width of the uneven settling basin It is possible to prevent the sludge or scum 42 from leaking to the rear of both sides of the part 31.

In addition, in the case where there is a groove or small protrusion on the bottom surface of the settling basin 20, the sludge caught in the groove or between the protrusion and the bottom surface cannot be effectively removed.
