The present invention relates to a mixed tank type sedimentation apparatus for separating and removing sedimentation generated during treatment in sewage treatment plants.

In general, the sewage relay pump, rainwater drainage pump, and terminal sewage treatment plant prevent pollution of discharged water, sediment of sediment in inflow water, and wear loss and blockage caused by sand in the treatment facility after settlement. In order to smooth the place.

The sedimentary deposits settle as much minerals and organics as possible, so as not only to physically clean the sewage, but also to remove the sediments by moving them out of the settlement.

If the sediment is not completely removed from these settlements, the organic contaminants mixed during the sedimentation will corrode and give off odors and worsen the water quality.

Therefore, for effective sewage treatment, decay accumulated on the sedimentation site is removed, and the general sedimentation removal process includes a lifting step of spreading the sedimentation of the sedimentation area, a washing step of washing the uplifted sedimentation, and a transfer step of transferring the washed sedimentation to the hopper. In this case, the sediment stored in the hopper is transported to the landfill.

Referring to the operation of the mixing tank-type sedimentation apparatus according to an embodiment of the present invention configured as described above are as follows.

First, the sedimentation sprinkled from the sedimentation paper by the sedimentation lifting device 5 is poured into the mixing tank 10, and the sedimentation introduced into the mixing tank 10 is discharged by the operation of the main screw conveyor 14. 12) is introduced into the sedimentation dehydrator (30).

In this case, the lifted sediment passes through the coarse contaminant removing unit 26 in the process of flowing into the mixing tank 10 to filter out large contaminants contained in the sediment, and the contaminant removing unit 26 is movable in structure. Positioning can be adjusted to the lifting device 5 and close, and by moving to one side can be separated from the mixing tank 10 through the edge of the mixing tank 10 it is possible to easily remove the filtered contaminants.

In addition, since the mixed water is supplied from the mixed water nozzle 22 into the mixing tank 10 at the position where the sediment is introduced into the mixing tank 10 to increase the water content of the fine sand, the flow of the sand through the main screw conveyor 14 is increased. In addition, in the mixing tank 10, high pressure air is injected from the air nozzle 18 to the sintering so that the odor-causing organic substance in the sintering is evaporated, and the sintering is uniformly dispersed by the air pressure and the main screw conveyor Transfer by (14) is made more smoothly.

At the tip of the discharge pipe 12, the washing water is injected from the washing water nozzle 24 toward the main screw conveyor 14 inside the discharge pipe 12 at a high pressure. By eliminating this neatly, the decay of acupuncture is actively prevented.

The support bearing unit 16 can easily perform maintenance of the oilless bearing 164 supporting the main screw conveyor 14 in the structure of the outer cover 162 attached to the screw fastening easily detachable.

Then, the sedimentation discharged through the discharge pipe 12 is introduced into the sedimentation dehydrator 30 to remove moisture, which will be described below.

First, the screw conveyor 33 is interlocked in opposite directions by rotating driven gears 332 and 342 respectively provided on the upper end of the rotating shaft 331 by the drive gear 351 connected to the drive motor 35. .

The sedimentation discharged from the discharge port 121 of the discharge pipe 12 flows into the hopper part 311 of the inflow drum 31 and is transported downward by the operation of the directional screw conveyor 33, and the hopper part 311. And at the lower end of the inflow drum 31, the moisture contained in the sedimentation is discharged to the outside through the discharge pipes (312, 313) to reduce the moisture content of the sedimentation.

Subsequently, the sedimentation transferred to the lower end of the inflow drum 31 is transferred to the discharge drum 32 through the communication gap 31a formed in the inflow drum 31 and the discharge drum 32, and to the discharge drum 32. The introduced sediment is transferred to the upper portion of the discharge drum 32 by the upward screw conveyor 34 and discharged to the air conveyor 50 through the discharge port 322.

In the operation of the immersion dehydrator 30, according to the upper bearing unit 36, the thrust bearing 362 exerts a proper bearing force against the pressure applied vertically upward to the rotation shaft 331 of the screw conveyor 33. The rotating operation of the screw conveyor 33 is stably maintained, and in particular, the operation of the screw conveyor 33 in which the relative repulsive force is generated upward due to the downward conveyance of sedimentation is maintained stably.

In addition, by the upper deflector 38 disposed below the upper bearing unit 36, the settling is prevented from coming up close to the upper bearing unit 36.

The lower bearing unit 37 has an oil seal 375 in close contact with the rotating shaft 331 of the screw conveyor 33 by the upper cover 378, and the upper cover 378 and the bearing housing 371. Due to the characteristics of the so-called double sealing structure in which a plurality of packing rings 376 are interposed between the lower cover 374 and the bearing housing 371, the sedimentation gap between each cover 378, 374 and the bearing housing 371. Since it effectively prevents penetration into the radial bearing 372 or the tapered roller bearing 373 through, the operation stability is firmly maintained.

In addition, according to the lower deflector 39 disposed above the lower bearing unit 37, the holder 392 closely wraps the outer surface of the rotating shaft 331 of the screw conveyor 33 through the rubber packing 391. In addition, since the anti-settling film 394 (394 ') is attached to the upper and lower portions of the lower deflector 39, respectively, the infiltration of sedimentation is more actively blocked.

Both holders 392 and 392 ′ of the lower deflector 39 can be easily combined / separated by a screw fastening method so that the rubber packing 391 can be easily replaced when worn.

On the other hand, since the sedimentation transferred to the lower portion of the inflow drum 31 is a state in which much water is removed, the sedimentation at the lower end of the downward screw conveyor 33 may be stacked without flowing to the discharge drum 34 side. According to the dispersion plate 40, the solidification phenomenon of sedimentation is effectively prevented.

That is, while the needle scattering plate 40 rotates together with the rotating shaft 331 of the downward screw conveyor 33, the blade 402 formed on the bottom surface of the main body part 401 is settled on the bottom of the inflow drum 31. By sweeping and dispersing in the circumferential direction, the sedimentation does not stack and flows to the discharge drum 32 side.

In addition, according to the embodiment of the present invention, when there is a risk that the sediment introduced into the inflow drum 31 may overflow without being transferred to the discharge drum 32, this phenomenon is prevented by the emergency transport means. The operation of the means is described as follows.

First, the communication cover 301 basically maintains a state in which the internal space is blocked by the baffle 302 inserted and inserted in the middle thereof (see FIG. 13A), and the inlet drum 31 is continuously laminated with water level. When is reached to reach the level switch 303 of the hopper unit 311, the level switch 303 detects this to generate a warning signal so that the operator can take appropriate measures.

When the operator takes out the blocking baffle 302 inserted into the communication cover 301 between the drums 31 and 32 from the communication cover 301, the communication hole between the drums 31 and 32 31b) The internal space of the communication cover 301 connecting the 32b is opened, so that the sedimentation in the inflow drum 31 does not go down to the lower end of the inflow drum 31 and discharges through the internal space of the communication cover 301 immediately. The transfer to 32 makes it possible to prevent the overflow phenomenon (see FIG. 13B).

The sedimentation discharged from the immersion dehydrator 30 flows into the air chamber 51 of the air conveyor 50, and then is transferred to the air piping 51 by the high pressure air supplied to the air chamber 51 and the discharge port 52. It is transferred to the storage hopper 60 through.

During the transfer of the acupuncture by the air conveyor 50, a large air pressure acts on the discharge port 52 by the action of the first regulator valve 57, and the action of the second regulator valve 58 on the air chamber 51. Due to the relatively small air pressure acts so-called double pressure action is carried out so that the sedimentation is more smoothly transferred.

On the other hand, the conveying pipe 53 is connected to the storage hopper 60 in the air chamber 51 is a plurality of straight pipes 531, a curved pipe 532 connecting each of the straight pipes 531 as described above The straight pipe 531 of which wear is relatively small due to friction with sedimentation is made of stainless material, while the curved pipe 532 with high friction is used as a special casting material having excellent abrasion resistance. 53, the durability is improved, and the maintenance of the curve is also easy since the replacement of the curved tube 532 is easy.

As described above, according to the mixed tank-type sedimentation apparatus according to the present invention, since the sediment transferred to the mixed tank is washed by the air washing means and the sedimentary washing means, organic contaminants that cause odor and corruption are removed. In addition, the water content is reduced in the process of going through the immersion dehydrator.

Therefore, according to the present invention, there is an advantage in that the problem of environmental pollution such as odor generation or polluted water discharge due to sedimentation can be greatly reduced.
