Abstract

The present invention relates to a circular sludge collector using rapid coagulation and sedimentation. More specifically, the circular sludge collector has a separate coagulation bath in a sedimentation bath, and applies stirring force to raw water coming into the coagulation bath through an impeller for the coagulation and sedimentation of the sludge, thereby enhancing efficiency of the coagulation and sedimentation of the sludge. Accordingly, the circular sludge collector prevents the outflow of purified water with the sludge contained from occurring.

The sedimentation tank is a sludge or sludge contained in the raw water. The suspended sediment is used to separate suspended solids (solid particles dispersed in water) in the raw water by using a specific gravity difference to separate solids and liquids. Can be explained. The sedimentation tank should be able to effectively remove suspended solids from the raw water because it directly affects the water quality of the effluent (purified water) as the final process of the waste water treatment plant and the water purification plant.

The sedimentation tank has been developed in various forms such as a circular sedimentation tank and a rectangular sedimentation tank. The rectangular sedimentation tank has a relatively high performance as compared with the circular sedimentation tank. However, it is complicated in structure and complicated to install, which is costly and difficult to maintain. Therefore, although the performance of the circular sedimentation tank is somewhat lower than that of the rectangular sedimentation tank, the structure is simple and easy to install and is generally widely used.

The sludge settled to the bottom is decayed due to decay for a long time, and the sludge is floated again and floated to the raw water. The sludge precipitated is collected and discharged by providing a scraper rotating in the sedimentation tank as shown in the following Patent Document.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a rapid flocculation set-up circular sludge collector according to the present invention will be described in detail with reference to the accompanying drawings. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. Throughout the specification, when an element is referred to as "comprising ", it means that it can include other elements, rather than excluding other elements, unless specifically stated otherwise.

1 to 3, the sludge collector includes a circular sedimentation tank 2 in which raw water is received, and a circulating sludge collecting unit 2 in the center of the sedimentation tank 2 A scraper 5 formed to face the bottom of the settling tank 2 from the center of the settling tank 2 and brought into close contact with the bottom of the settling tank 2, A sludge discharge portion 6 formed at the center bottom of the sedimentation tank 2 for discharging the sludge collected by the scraper 5 to the outside; A flocculation unit 1 formed at the center of the sedimentation tank 2 for agitating and diffusing the sludge contained in the raw water by providing an agitation force to the raw water flowing into the sedimentation tank 2, .

The constitution of the sedimentation tank 2, the center wall 3, the driving unit 4, the scraper 5, the sludge discharge unit 6 and the purified water outlet 7 of the present invention is the same as the known technology, In the invention, the most important feature is that the aggregation part 1 is formed in order to improve the sedimentation efficiency of the sludge. As described above in the background art, the sludge particles are becoming finer due to the enhancement of the water treatment process. Accordingly, the settling of the sludge in the settling tank 2 is not properly performed, and the sludge is contained in the purified water as it is .

Therefore, in the present invention, agitation force is generated in the raw water through the agglomerate 1 to agitate the sludge, increase the collision frequency of the sludge, and actively form the flocs, thereby increasing the agglomeration efficiency of the sludge . Accordingly, it is possible to solve the problem that the sludge is not settled down and is contained in the purified water as it is and flows out. The high concentration sludge is discharged through the sludge discharging unit 6 to increase the reaction efficiency and the dewatering efficiency of the sludge, So that the usage amount can be reduced.

The flocculating portion 1 is provided with an agglomeration tank 11 for agitating and agglomerating sludge by generating an agitation force in the raw water flowing into the sedimentation tank 2 and forming a space in which raw water flows and flocculates, (12) for providing cohesive force to the raw water by stirring in the coagulation tank (11), and a sludge discharge unit (12) formed between the impeller (121) And a sludge consolidation cone (13).

The flocculation tank 11 is formed at the center of the sedimentation tank 2 so as to surround a drive shaft 42 to be described later and provides a space where raw water flows and agitates and agglomerates by the agitation reaction unit 12. The coagulation tank 11 is formed with a hollow cylindrical flocculation wall 111 on the upper side so that raw water can be introduced into and discharged from the flocculation tank 11 and a sludge settling induction plate So that the sedimentation of the sludge discharged from the flocculation wall 111 can be performed quickly. The flocculation tank 11 is provided with a raw milk inflow inlet 112 through which raw water flows, a spinneret 113 through which cohered raw water is discharged, raw water introduced through a raw milk feed inlet 112, 113 to prevent the liquid from escaping through the opening.

The flocculation wall 111 is formed to form an upper portion of the flocculation tank 11 and is formed to face the center wall 3 on the inner side of the center wall 3. A raw water inlet 112 is formed to communicate with the lower side of the flocculation wall 111 to receive raw water and a radial exhaust port 113 is formed along the upper side of the flocculation wall 111 So that raw water and sludge agitated and agglomerated by the agitating reaction unit 12 are discharged to the outside of the agglomeration tank 11.

The raw milk inflow inlet 112 is configured to allow raw water to flow into the sedimentation tank 2 and is introduced into the flocculation tank 11 first. More specifically, the raw milk inflow inlet 112 is formed so as to communicate with a lower side surface of the flocculation wall 111, and is prevented from flowing upwardly of the flocculation wall 111 by the blocking plate 114, So that the impeller 121 of the crosshead reactor 12, which will be described later, is introduced into the inner space of the sludge settling plate 115. Therefore, the raw water introduced through the raw milk inflow pipe 112 moves upward while agitating and coagulating the sludge by the upward flow generated by the impeller 121, (11).

The raw water flowing through the raw milk inflow inlet 112 is rotated by the impeller 121 of the crosshead reactor 12 to flocculate and precipitate the sludge, And a plurality of radial shapes are formed along the upper side of the cohesive wall 111. The radiant air outlet 113 is formed to face the center wall 3 so that the sludge discharged through the radiant air outlet 113 is clogged with the center wall 3 so that the sludge settling plate 115 , And is prevented from being discharged through the purified water outlet (7).

The blocking plate 114 is formed to protrude inward along the periphery of the cohesive wall 111 and is formed above the point where the raw milk inflow inlet 112 is communicated. Therefore, the raw water flowing through the raw milk inflow inlet 112 can not be clogged up by the blocking plate 114 and flows into the space surrounded by the sludge settling guide plate 115 through the raw water inlet 114a formed at the lower side do. Therefore, the raw water introduced through the raw milk inflow inlet 112 rises and forms an upward flow as the impeller 121 rotates. The raw water is agitated and agglomerated, and discharged through the radiant air outlet 113 do.

The sludge settling induction plate 115 extends from the lower end of the flocculation wall 111 and forms a lower portion of the flocculation tank 11. The impeller 121 is rotated in a space defined by the sludge settling guide plate 115 and the sludge contained in the raw water is agitated and coagulated to improve the coagulation efficiency. The sludge settling induction plate 115 is formed in a conical shape having a circular cross section so that the sectional area of the inner space becomes wider toward the lower side and is formed to face the lower side of the center wall 3. Therefore, the agglomerated sludge, that is, the flocculant, discharged through the radial air outlet 113 and clogged in the center wall 3 is settled to the bottom along the inclined sludge settling guide plate 115 and collected by the scraper 5 Thereby preventing the sludge from floating through the purified water outlet 7 while floating. In addition, the sludge settling plate 115 cuts off the center portion of the settling tank 2 in which an upward flow is generated by the impeller 121, so that the flocculated sludge is not settled down to the bottom, It is possible to further improve the coagulation efficiency and the sedimentation efficiency.

The agitation reaction unit 12 is configured to provide an agitating force to the raw water flowing into the flocculation tank 11 to generate agitation and agglomeration of the sludge contained in the raw water, The drive unit 4 that rotates the conventional scraper 5 is used to reduce the power consumed and simplify the structure of the apparatus. The agitation reaction unit 12 is connected between the impeller 121 rotating in the flocculation tank 11 and the driving unit 4 rotating the scraper 5 and the impeller 121, A driving force transmitting portion 122 for transmitting the driving force of the driving portion 4 to the impeller 121 and an impeller supporting portion 123 for supporting the impeller 121 to enable smooth rotation of the impeller 121 .

The impeller 121 is formed in the flocculation tank 11 and rotates. A plurality of blades protruding downward are formed to provide an agitating force to the raw water introduced through the raw water inlet 114a, So that rotation and ascending flow are generated. Therefore, the coagulation efficiency can be improved by stirring and coagulation of the sludge. The impeller 121 is formed to protrude downward from an impeller driving gear 122d which will be described later and formed to have a disk shape and rotates together with the impeller driving gear 122d. The driving force transmitted from the driving force transmitting portion 122 to the driving force To rotate. Since the rotational speed of the internal gear 122b is increased by the driving force transmitting portion 122, the impeller 121 can further improve the flocculation efficiency of the sludge through agitation and agglomeration.

The driving force transmitting portion 122 is formed between the impeller 121 and the driving portion 4 to transmit the driving force of the driving portion 4 to the impeller 121. The driving force transmitting portion 122 includes a driving shaft 42 connected to the scraper 5, So that the power consumed can be reduced and the structure of the apparatus can be simplified.

The driving disc 122a is fixed to the driving shaft 42 and rotates together with the driving shaft 42 so that the center of the driving disc 122a is inserted into the driving shaft 42 and fixed. The drive disc 122a is connected to the lower end of the internal gear 122b so as to be rotated together with the drive disc 122a and rotatably supported at the lower end thereof by a roller support rail (122a-1) are formed. The support roller 123a-2 to be described later of the impeller supporting portion 123 is inserted into the roller support rail 122a-1 and rotates. The impeller 121 is supported by the driving disc 122a and smoothly rotated .

The internal gear 122b is fixed to the lower side of the driving disk 122a and is formed in a circle having a shape corresponding to the driving disk 122a and has gear teeth formed therein, The first drive transmission gear 122c-1 is engaged and rotated.

The drive transmission gear 122c is formed between the internal gear 122b and the impeller drive gear 122d to transmit the rotation of the internal gear 122b to the impeller drive gear 122d. So that the impeller 121 can be agitated and agglomerated. The drive transmission gear 122c is formed to have a smaller size than the internal gear 122b to increase the rotation speed of the internal gear 122b and to form a plurality of teeth at regular intervals along the internal periphery of the internal gear 122b So that the impeller driving gear 122d rotating in engagement with the inside of the driving transmission gear 122c has a diameter smaller than that of the internal gear 122b, so that the rotational speed is increased. In addition, the drive transmission gear 122c includes a first drive transmission gear 122c-1 that engages with the internal gear 122b to further increase the rotation speed; A second drive transmission gear 122c-2 rotating in engagement with the drive transmission gear 122c and having a larger diameter than the first drive transmission gear 122c-1; The first drive transmission gear 122c-1 and the second drive transmission gear 122c-2 are inserted into the centers of the first drive transmission gear 122c-1 and the second drive transmission gear 122c-2, And a gear connection shaft 122c-3 for causing the gears to rotate together.

The first drive transmission gear 122c-1 is formed between the internal gear 122b and the impeller drive gear 122d so as to be engaged with the internal gear 122b, and a plurality of the internal gears 122b The rotational speed of the first drive transmission gear 122c-1 and the internal gear 122b is reduced by a factor of several times larger than that of the internal gear 122b, As the gear 122c-1 becomes smaller, the rotation speed of the first drive transmission gear 122c-1 becomes faster.

The second drive transmission gear 122c-2 is inserted into the gear connecting shaft 122c-3 and rotates to engage with the impeller driving gear 122d inward. The second drive transmission gear 122c-2 is inserted into the first drive transmission gear 122c-1 and the gear connection shaft 122c-3 and rotates together, so that the first drive transmission gear 122c- And the rotation speed increased by the rotation speed is equal. The second drive transmission gear 122c-2 has a larger diameter than the first drive transmission gear 122c-1 so as to have a circumferential speed that is faster than the first drive transmission gear 122c-1 So that the increased circumferential speed is transmitted to the impeller drive gear 122d meshing with the inside.

The impeller drive gear 122d is configured to engage with the inside of the second drive transmission gear 122c-2 and to rotate by receiving the rotational force of the second drive transmission gear 122c-2. (42). ≪ / RTI > The impeller drive gear 122d is formed with a plurality of second drive transmission gears 122c-2 at predetermined intervals along the circumference thereof. The first drive transmission gear 122c-1 and the second drive transmission gear 122c- 122c-2. The rotational speed of the impeller driving gear 122d decreases as the size of the first drive transmission gear 122c-1 decreases and as the size of the second drive transmission gear 122c-2 increases, The speed of the impeller 121 can be maximized by controlling the sizes of the gears to maximize the flocculation efficiency of the sludge.

The impeller supporting portion 123 is configured to support the impeller 121 and more precisely the impeller driving gear 122d to which the impeller 121 is fixed so that the impeller supporting portion 123 can rotate smoothly. And a lower support portion 123b for supporting the lower side of the impeller driving gear 122d. The lower supporting portion 123b is supported by the upper supporting portion 123a.

The upper support part 123a is supported on the upper drive plate 122a so that the impeller drive gear 122d is supported in the form of being suspended from the upper drive plate 122a, 123a-1); And a support roller 123a-2 connected to the end of the upper linking member 123a-1 so as to be rotatable on both sides and rotated by being supported inside the drive disc 122a.

The support roller 123a-2 is connected to the end of the upper linking member 123a-1 so as to be rotatable on both sides, and is formed in a circular shape and rotates along the roller support rail 122a-1. Accordingly, the impeller driving gear 122d rotates along the roller support rails 122a-1 even when the impeller driving gear 122d interrupts the rotation, thereby enabling stable rotation.

The lower supporting portion 123b is configured to support the lower side of the impeller driving gear 122d and includes a lower roller 123b-1 rotatably connected to the lower end of the impeller driving gear 122d; And a support plate 123b-2 fixed to the driving shaft 42 of the driving unit 4 and supporting the lower roller 123b-1 and rotating the lower roller 123b-1.

The sludge compacting cone 13 is formed between the impeller 121 and the sludge discharge section 6 to improve the flocculation efficiency and sedimentation efficiency of the sludge. The sludge concentration cone 13 is fixed to the drive shaft 42, As shown in Fig. Therefore, the sludge consolidation cone 13 has a slope that becomes smaller in cross section toward the upper side and the lower side. The sludge collecting cone 13 is formed on the upper side of the sludge collecting groove 61 of the sludge discharging unit 6 so that sludge accumulated in the sludge collecting groove 61 flows upwardly by the rotation of the impeller 121, The sludge is discharged at a high concentration to increase the reaction efficiency in the reaction tank and to reduce the amount of the chemical used. At this time, the sludge consolidation cone 13 has a slope that becomes smaller in cross-sectional area as it goes downward, so that the sludge floated is clogged by the sludge consolidation cone 13 so that it can be collected more efficiently by the sludge collection grooves 61. Since the sludge consolidation cone 13 is formed to have a slope that becomes smaller in cross section toward the upper side, the flocculation of the sludge is not performed so much that the sludge floating in the sedimentation tank contacts the sludge consolidation cone 13, So that it can be piled up in an ascending flow due to the rotation of the impeller 121, so that stirring and coagulation can be performed again. Therefore, the flocculation efficiency of the sludge can be further improved, and the flocculating sludge flows into the impeller 121 side again, so that the density of the sludge in the flocculation tank 11 becomes higher, thereby maximizing the flocculation efficiency of the sludge.

3, the raw water (a) flowing through the raw milk inflow inlet 112 is rotated by the impeller 121, and the ascending flow The sludge is agitated and agglomerated and discharged out of the agglomeration tank 11 through the radial air spout 113.
