Description

Sewage collecting well for solid and liquid separating

The present invention prevents the dispersion of foreign matters in the sewage introduced by the structure and the filtration column of the sump, separates sediment and suspended matters, and can treat the remaining foreign matters by the filtration column, thereby increasing the sewage treatment efficiency. When the inflow water level rises, the sedimentation material, suspended foreign matter and sewage inside the sump are forced to drain through the suction pump to automatically clean the sump and prevent backflow of sewage. Sediment, sediment and foreign matter separated in the chamber of the sewage can be discharged to the outside by the suction of only the operation of the suction pump and the water level is related to the sewage solid-liquid separation basin to save energy.

In recent years, domestic wastewater and industrial wastewater are increasing day by day, and such wastewater and wastewater include foreign substances such as suspended solids and earth and sand. These foreign matters are loaded and decayed for a long time in the sump or sewage pipe, causing odor, which can cause people unpleasant.

The foreign matter accumulated in the sump or sewage pipe is disposed of by manpower. The conventional technique for solving this problem is to use a dredge suction vehicle. Specifically, dragging the hose through the manpower to enter the sump or sewer pipe to suck the sludge, or to carry out the dredging operation using a small skid rotor in the middle of the diesel construction. However, the equipment is also difficult to work with due to the large amount of water flowing in the sump or sewage pipe, and there is a danger of poisonous gas (ammonia) and soot caused by decay.

In addition, when there is a rainy area or a heavy rain, living sewage flowing in the sewage pipe due to a large amount of rain and sludge such as suspended solids or earth and sand loaded in the sewage easily flow back through the sump.

To prevent such damages, it is necessary to install a backflow prevention facility for sewage pipes and water collection facilities such as each home or a shopping mall, and preventive inspection such as thorough water management. There is a problem that can not be installed.

Based on these problems, the present inventors have developed Korean Patent Registration No. 931674, "Sewage Treatment System". When the sewage level rises above a certain height in the sump by the present technology, the present inventors automatically recognize sewage water containing foreign matters. By discharging, it was possible to solve the backflow problem of the prior art.

However, according to the present technology, when the sewage flows into the sump and removes the foreign matter by the filtration column and the suction pump, the foreign matter is dispersed in the sewage so that the sediment does not settle properly. there was.

The present invention is to prevent foreign matter from being dispersed in the sewage from the sewage flowing into the sump (10), such as homes, stores, factories and roads to filter out deposits and floating foreign matters first, and secondly to remove the remaining foreign matters. In addition to discharging the treated water removed through the filtration column (30), when a certain level is reached in the sump (10), the sewage and the sewage flowed together with the separated sediment and floating foreign matter is automatically discharged or reintroduced or It is possible to discharge only the treated water through the treatment device of the, and relates to a device that can prevent inundation damage in advance by blocking the reverse flow of sewage during the rainy season.

Here, the term "sewage" is a generic term for sewage and wastewater flowing from homes, stores, factories and roads.

In addition, the term "sedimentary substance" refers to a foreign substance that is settled because the specific gravity is greater than water, and "floating foreign substance" refers to a foreign substance that is suspended due to the specific gravity is smaller than water, and the "remaining foreign substance" is a specific gravity. Similar to water, it refers to foreign matter that flows with water. Therefore, in the present invention, the foreign matter is first separated by specific gravity, and the non-separated foreign matter is separated by filtration to double the efficiency of removing foreign matter from sewage.

Referring to Figure 1, etc., it can be seen that the present invention consists of a sump well 10, a suction pump 20, a filtration column 30, a lower suction pipe 40 and a floating material suction pipe 50.

First, the water collecting well 10 includes a plurality of chambers 14 formed by a plurality of partition walls 13, an inflow pipe 11 formed on one side, and a drain pipe 12 formed on the other side.

The inflow pipe 11 is connected to sewage pipes, sewage pipes, etc. from each home, factory, etc. so that sewage flows into the collection basin 10. The drainage pipe 12 corresponds to a configuration in which the introduced sewage is discharged to the outside via the chamber 14 and the filtered water filtered through the filtration column 30. In this case, for the smooth inflow and outflow of sewage, the drain pipe 14 is preferably formed at a relatively lower position than the inlet pipe (11).

Meanwhile, the present invention constitutes a partition wall 13 and a chamber 14 in the sump 10 as shown in FIG. 1, but a sedimentation chamber A in which sewage flows from the inflow pipe 11 to deposit foreign matters. ), A floating chamber (B) in which sewage flows to both sides of the deposition chamber (A) to float foreign matters, and a treatment chamber for treating the remaining foreign matters from the sewage through the filtration column by allowing sewage to overflow from the floating chamber. (C).

In the present invention, the interior of the sump (10) is divided into a deposition chamber (A), a floating chamber (B) and the processing chamber (C), the embodiment is shown in Figure 1 and the like.

To explain this, first and second partitions 131 and 132 are configured in parallel in the sewage flow direction (inflow pipe 11 to drain pipe 12 direction) in the inside of the sump well 10. A third partition 133 intersecting between the two partitions 131 and 132 is configured, and a fourth crosses the sidewalls (not shown) of the first and second partitions 131 and 132 and the sump well 10, respectively. And fifth partitions 134 and 135, and sixth partitions 136 intersecting end portions of the first and second partitions 131 and 132 and both side walls of the water collecting well 10.

As the partition wall is configured, the first and second partitions 131 are partitioned by the first and second partitions 131 and 132 and the third partition 133. 132, the second chamber 142 is partitioned by the third partition 133 and the sixth partition 136, and the first and second partitions 131 and 132 and the fourth and fifth partitions 134 and 135. And third and fourth chambers 143 and 144, respectively, and are divided into fifth and sixth partitions by the first and second partitions 131 and 132, the fourth and fifth partitions 134 and 135, and the sixth partition 136, respectively. The chambers 145 and 146 are partitioned, respectively, and finally, the seventh chamber 147 is formed outside the sixth partition 136 (in the direction of the drain pipe 12).

By this division, the deposition chamber A corresponds to the first and second chambers 141 and 142, and the floating chamber B corresponds to the third and fourth chambers 143 and 144 and the fifth and sixth chambers 145 and 146. The treatment chamber C corresponds to the seventh chamber 147.

Meanwhile, an upper flow passage 17 and a lower flow passage 18 are formed to allow the sewage introduced between the chambers 14 to flow. The first and second partitions 141 are formed at both sides of the first chamber 141. A groove is formed at the upper end of the 131 and 132 to form a first upper flow path 171, and the groove is formed at the upper end of the first and second partitions 131 and 132 in both sides of the second chamber 142. A second upper flow path 172 is configured, and grooves are formed in the fifth and sixth chambers 145 and 146 at the upper end of the sixth partition wall 136 to form a third upper flow path 173. In this case, the first upper flow passage 171 and the second upper flow passage 172 are configured to have a height higher than that of the third upper flow passage 173 to allow a smooth flow of the introduced sewage.

On the other hand, the lower flow path 18 is composed of a first lower flow path 181 between the first partition 141 and the second chamber 142 between the third partition 133 and the lower partition wall 15 to be described below. Between the fourth and fifth partitions 134 and 135 and the lower partition wall 15 between the third chamber 143, the fifth chamber 145, and the fourth chamber 144 and the sixth chamber 146, respectively. The second lower flow passage 182 is configured.

Based on the configuration as described above, the sewage flowing into the sump 10 is first introduced into the first chamber 141 and flows into the second chamber 142 through the first lower flow passage 181. Here, the lower partition wall 15 of the second chamber 142 is lower than the lower partition wall 15 of the first chamber 141, and the shape of the lower partition wall 15 in the second chamber 142 is centered. Should be configured to be low. This configuration allows the introduced sewage to flow naturally from the first chamber 141 to the second chamber 142, and deposits foreign matter from the sewage stored in the second chamber 142 to the lower compartment of the second chamber 142. This is to gather at the center of the wall (15). That is, the second chamber 142 corresponds to a configuration to separate the deposit material from the incoming sewage. Although the first chamber 141 is not shown in the drawing, a vortex plate may be formed to reduce the flow rate to the inflow sewage and generate vortices to easily separate deposit materials from the second chamber 142 (precipitation). To do so.

When the sewage flowing into the second chamber 142 continues to flow in this way, the water level rises and flows to the third and fourth chambers 143 and 144 by overflowing the first upper flow path 171 and the second upper flow path 172. In addition, the sewage flowing into the third and fourth chambers 143 and 144 flows into the fifth and sixth chambers 145 and 146 through the second lower flow passage 182 as the water level rises. The reason for constituting the third and fourth chambers 143 and 144 is that the sediment is filtered from the sewage introduced from the second chamber 142, and the sewage from which the sediment is filtered is overflowed to both sides so that the floating foreign matter is discharged to the third and fourth chambers 143 and 144. This is to separate the foreign matter mixed in the sewage by specific gravity by allowing the four chambers (143, 144). In addition, the reason for configuring the fourth and fifth partitions 134 and 135 and the fifth and sixth chambers 145 and 146 is to concentrate the foreign matter suspended in the third and fourth chambers 143 and 144, which will be described below. This is to double the removal efficiency of the suspended matter from the sewage through the suction pipe (50).

The sewage flowing in this way is elevated in the third and fourth chambers 143 and 144 and the fifth and sixth chambers 145 and 146 so as to flow over the third upper flow channel 173 and flow into the seventh chamber 147. The sewage flowing in this way is to pass through the filtration column 30 while the sediment and floating foreign matters are removed so that the treated water filtered out of the remaining foreign substances is discharged through the drain pipe 12.

Meanwhile, the sump well 10 is divided into upper and lower portions by the lower partition wall 15, and the lower partition wall 15 is formed under the sump well 10 so that the lower partition wall ( 15 is a lower surface (bottom surface) of each chamber 14, and a lower suction pipe 40 and a second lower suction pipe 60 to be described below are mounted inside the lower partition wall 15. The space 16 is formed.

As shown in FIG. 1, the suction pump 20 is configured in the second chamber 142, and a discharge tube 21 is formed at a side thereof, and the discharge tube 21 is formed of the suction pump 20. By the operation, the material deposited in the second chamber 142 and the foreign matter suspended in the third and fourth chambers 143 and 144 and the foreign matter deposited in the seventh chamber 147 together with the sewage are discharged to the outside. Corresponds to the configuration. Sediment and floating foreign matter in the seventh chamber 147, the sediment and suspended matter is sedimented and suspended while the sewage in the state in which the deposition material and the suspended foreign matter is filtered and stored in the seventh chamber 147, as well as the filtration described below. After the cleaning of the column 30, the foreign matter deposited and suspended from the filter medium 34 is included. The discharge pipe 21 is not shown in the drawing, but may be connected to a separate processing device to remove the foreign matter and then introduce the water from which the foreign matter has been removed into the drain pipe 12.

The suction pump 20 is composed of a pump body 22 and a pump support 23, as shown in Figure 4, the pump body 22 is not shown in the drawing, but the motor is mounted therein By generating the suction force, the foreign matter or the like is discharged to the discharge tube 21 by the suction force. Since the function of such a pump is a well-known technique, the description thereof is omitted.

The pump support 23 has a suction hole 24 formed in a circumferential portion of the pump support 23 in the form of an expansion pipe, and foreign matter deposited in the second chamber 142 based on the configuration of the suction hole 24. It is to be sucked through the 24 to be discharged to the discharge pipe (21). In addition, the pump support 23 is mounted to be sealed with the concave groove 151 formed in the lower partition wall 15, the assembly 151 is a lower suction pipe 40 to be described later And it is configured to communicate with the second lower suction pipe (60). That is, the collection unit 151 is a space in which foreign matter and water sucked from the suction pipe 40 and the second lower suction pipe 60 are collected, and the foreign matter and water collected in the collection unit 151 are pumped back 23. And to be discharged to the discharge pipe 21 through the pump body 22.

Meanwhile, the filtration column 30 is configured in the seventh chamber 147 as described above. Hereinafter, the filtration column 30 will be described with reference to FIGS. 5 and 6.

The filtration column 30 is a drain chamber 32 for discharging the treated water while holding the upper chamber 31 and the lower filtration chamber 33 to which the rotational force is applied by the motor 311 as a basic example, and the upper chamber. The filtration chamber 33 rotated by the rotational force from 31, the filtration material 34 inside the filtration chamber 33, and the support plate 35 on which the filtration chamber 33 is placed are used as components.

When the component is described in detail, the upper chamber 31 has a space formed therein and a motor 311 is mounted therein in a shape in which a lower surface thereof is opened. The motor 311 is not shown in the figure, but can be operated manually or at a certain level, automatically at a certain time.

The drain chamber 32 is formed at the lower portion of the upper chamber 31, and the receiving chamber 322 is formed at the lower end of the drain chamber 32 in a tubular shape having a larger diameter so that the filtering chamber is located inside the receiving chamber. (33) The top is configured to be inserted.

Inside the drain chamber 32, a rotating rod 321 integrally interlocked with the motor 311 is configured, and is configured to communicate with the drain pipe 12 at its side. The treated water passing through the filtration chamber 33 rises to the drain chamber 32 to be discharged to the outside through the drain pipe 12. The drain pipe 12 is not shown in the drawing, but it is reasonable to configure the reverse displacement to prevent the back flow of smell and the like from the outside to the drain pipe 12.

The filtration chamber 33 has an outer portion 331 in which a plurality of first filtration holes 3311 are formed, and a plurality of second filtration holes 3331 formed in a predetermined gap with the outer portion 331. It consists of the tube part 332. The exterior part 331 and the inner tube part 332 are connected to each other by a joint part 333 at an upper end thereof, and a plurality of first flow holes 3331 are formed in the joint part 333. In the space formed by the exterior part 331, the inner tube part 332, and the joint part 333, a filter material 34 to be described below is disposed. In addition, the exterior part 331 and the inner tube part 332 are connected to each other by a closing plate 334 at the lower end, the closing plate 334 is hollow (3341) is formed in the center. In addition, a plurality of third flow holes 3332 are formed in the closing plate 334. The third flow hole 3332 functions as a hole through which suction force acts toward the filter medium 34 during cleaning. It is reasonable that the closing plate 334 is configured to be detachable to the exterior portion 331 and the inner tube portion 332, which means that the placement and disassembly of the filter material 34 based on the attachment and detachment of the closing plate 334 To facilitate it. The detachable structure of the closing plate 334 may be configured in various ways, the description thereof will be omitted.

In addition, a lower surface of the inner tube portion 332 has a protrusion 3322 formed on a closed surface to be inserted into the hollow 3331 of the closing plate 334, and a hemispherical protrusion 3333 is further formed on the protrusion 3322. It is configured to prevent the eccentricity in the entire rotation of the filtration chamber 30 by inserting the protruding protrusion 3323 into the settle groove 351 formed on the upper surface of the support plate 35 to be described below.

In addition, a fastening frame 335 is configured at an upper end of the inner tube part 332, and the fastening frame 335 is connected to the rotating rod 321 and integrally behaves. A plurality of second flow holes 3331 are formed in the fastening frame 335. In this way, the rotation is transmitted from the rotating rod 321 to the fastening frame 335, the rotational force is applied to the filtration chamber 33 that is integrally behaves with the fastening frame 335.

In addition, an inserting portion 336 having a smaller diameter is formed at an upper portion of the exterior portion 331 so that the inserting portion 336 is inserted into the receiving portion 322. In this way, the filtration chamber 33 is prevented from being eccentric by the protrusions 3323 and the settling groove 351 in the lower part, and the eccentricity is prevented by forming the insertion part 336 and the receiving part 322 in the upper part of the filtration chamber. The chamber 33 is to enable the rotation without tilting. In addition, the insertion portion 336 has a rim groove 3301 formed at its outer circumference, and a packing 337 is formed therein, and the packing 337 has a ring shape and has an opening 3371 at one side thereof. Is characterized in that is formed. That is, the packing 337 is expanded in diameter by centrifugal force when the filtration chamber 33 rotates while being mounted in the rim groove 3331 of the insertion part 336. ) Is configured to contact the inner circumference of the receiving portion (332). The reason why the packing 337 is formed in this way is that unfiltered sewage flows between the insertion part 336 and the receiving part 332 when the filtration chamber 33 rotates and flows out through the drain pipe 12. This is to prevent. In addition, the packing 337 is configured in a pair as shown in the figure, it is reasonable to configure each opening 3371 to cross each other to prevent the sewage leakage through the opening 3371.

The first filtration hole 3311 of the exterior portion 331 is introduced into the drainage pipe 12 through the first flow hole (3331) of the joint 333 after the sewage flows in and is filtered by the filter medium 34 The filtered treated water is to flow out, and when cleaning, foreign substances such as sludge caught in the filter medium 34 to the first filtration hole 3311 is leaked out.

In addition, the second filtration hole 3331 of the inner tube part 332 allows the sewage having passed through the first filtration hole 3311 and the filter medium 34 to be filtered once more, thereby providing a plurality of second pluralities of the fastening frame 335. The treated water filtered through the flow hole 3331 is to be discharged to the drain pipe (12).

The filter medium 34 is a cylindrical shape forming a hollow (not shown in the figure.), The inner tube portion 332 is embedded in the hollow, the filter medium 34 is not limited to the material, but an example of stainless The tangled shape of the strip can be presented, and thus the filtration medium 34 is entangled with the stainless strip to filter foreign matter from the sewage, as well as to the filter medium 34 based on the rotation of the filtration chamber 33. This is to generate centrifugal force and to easily flow foreign matter deposited between the gaps of the filter medium 34 by the centrifugal force to the outside. In addition, the filter medium 34 is formed of a stainless strip to prevent rust.

The support plate 35 is placed below the filtration chamber 33, and the support plate 35 is configured to allow the filtration chamber 33 to be placed thereon so that it can be easily rotated when a rotational force is generated. . To this end, an upper surface of the support plate 35 constitutes a settling groove 351, and a protrusion protrusion 3323 formed in the filtration chamber 33 is inserted into the settling groove 351 so that the inside of the settling groove 351 is formed. The protrusion 3333 is to be rotated.

In addition, it is reasonable to configure one or more support plates 36 between the upper chamber 31 and the support plate 35 in the filtration column 30. The reason for configuring the support plate 36 is to prevent the eccentricity from occurring when the filtration chamber 33 is rotated, and to reduce the contact area with the sewage into which the filtration chamber 33 is introduced, thereby preventing the load of the motor 311. At the same time to increase the rotational speed to increase the desorption efficiency of foreign matter from the filter medium (34).

On the other hand, the filtration column 30 is mounted on the seventh chamber 147, the lower surface of the seventh chamber 147 on which the lower surface of the support plate 35 is mounted, i.e., the recess 152 on the lower partition wall 15. ) Is formed, and configured to communicate with the lower suction pipe 40, it is reasonable that a plurality of suction holes 153 are formed between the support plate 35 and the recess 152. As the suction hole 153 is formed as described above, the suction material of the suction pump 20 may be sucked with the water in the seventh chamber 147 through the lower suction pipe 40.

Hereinafter, the operation of the filtration column 30 will be described.

First, the sewage is introduced through the first filtration hole 3311 of the filtration chamber 33 and the introduced sewage is filtered through a filter material 34 to filter foreign matter such as sludge, and the treated water is formed in the joint 333. It is introduced into the drain chamber 32 through the first flow hole (3331), and the treated water thus introduced is discharged to the outside through the drain pipe (12). In addition, the sewage introduced through the first filtration hole 3311 of the filtration chamber 33 passes through the filter medium 34 and into the inner tube part 332 of the filtration chamber 33 through the second filtration hole 3331. Bar water may be introduced into the drainage chamber 32 through the second flow hole 3331 formed in the fastening frame 335, and the treated water may be introduced to the outside through the drain pipe 12. To be discharged.

When the sewage is filtered using the filter column 30, foreign substances such as sludge are deposited on the filter medium 34, thereby lowering the filtration efficiency of the filter column. In this case, when the motor 311 is operated automatically or manually, the rotational force is transmitted to the filtration chamber 33 by the rotating rod 321 and the fastening frame 335, and the rotational force W1 of the filtration chamber 33 is filtered. The centrifugal force (O) is applied to the filter medium 34 in the chamber 33 so that foreign matters S1 such as sludge deposited in the gap of the filter medium 34 by this centrifugal force flow out through the first filtration hole 3311. The filter medium 34 is cleaned. At the same time, the centripetal force W2 in the upward direction acts on the inside of the inner tube part 332 inside the filtration chamber 33, and this centripetal force W2 is the second filtration hole of the inner tube part 332. 3321, the filter medium 34 and the third flow hole (3342) of the closing plate 334, the suction force (I1) acts, this suction force (I1) is the agent is mounted on the lower surface of the support plate (35) At the lower surface of the seven chamber 147, the suction force I2 acts on the suction hole 153 and the recess 152 so that the deposition material S2 collects in the recess 152. That is, based on the structure of the filtration chamber 33, the suction hole 153, and the concave groove 152, the foreign matter deposited as a result of the cleaning at the same time as the filter medium 34 is cleaned, collects in the concave groove 152. By suction of the suction pump 20 is to be able to remove the deposited material through the lower suction pipe (40).

The filtration column 30 as described above is configured in the seventh chamber 147, an example in which two are configured in FIG. 1 is illustrated. As such, when two filtration columns 30 are configured, both filtration columns 30 may be repeatedly cleaned and operated to enable continuous filtration without interruption.

Meanwhile, the present invention allows the floating suction pipe 50 to be further configured to remove the foreign matter by suction, and the floating suction pipe 50 has an upright tubular shape, and the suction pump 20 and the second lower suction pipe. It is a configuration connected to (60). The float suction pipe 50 is composed of a plurality, the installation position may be selectively configured, but when configuring the chamber 14 as in the embodiment of Figure 1, etc. of the present invention as described above It is reasonable to allow the three and four chambers 143 and 144 to be discharged to the outside. In addition, it is preferable that the seventh chamber 147 is also configured, and as mentioned above, the foreign material separated from the filter medium 34 after cleaning the sewage and the filtration column 30 introduced into the seventh chamber 147. By discharging the floating foreign matter to the outside, the floating foreign matter can be almost completely removed from the sewage.

As mentioned above, the present invention allows the operation of one suction pump 20 to remove the deposit foreign matter from the second chamber 142 and the seventh chamber 147, and at the same time, the third and fourth chambers 143 and 144. ) And the seventh chamber 147 to remove the floating foreign matter to easily remove the foreign matter, and if a certain level or more is to suck the water together with the foreign matter to be discharged to the outside to automatically solve the problem of backflow.

In summary, the present invention prevents the dispersion of foreign matters in the sewage introduced into the chamber 13 structure of the sump well 10 so that the deposited foreign matters and floating foreign matters are sorted, and the primary treatment water thus selected is filtered column 30 By passing through), it is possible to double the filtration efficiency by removing the remaining foreign matter mixed in the primary treatment water to discharge the secondary treatment water to the outside.

In addition, the filtration column 30 can be cleaned by the rotational force by automatic or manual to prevent the blockage of the filter medium and at the same time to increase the filtration efficiency in the case of a plurality of operations as well as to continue to discharge the treated water during cleaning. Will be.

In addition, the present invention is to prevent the backflow problem in flooding, etc. by the operation of the foreign material intake and discharge line as shown in Figure 7, and to remove the deposited foreign matter and floating foreign matter separated in the sump. The foreign material suction and discharge lines are connected to the suction pump 20 and the suction pump 20, and are connected to the lower suction pipe 40 and the suction pump 20 communicating with the chamber in which the foreign matter is deposited. The second lower suction pipe 60 is connected to the floating suction pipe 50 formed in the chamber in which the floating foreign matter is floating. Based on this configuration, when a certain level is reached in the sump 10, although not shown in the drawing, the suction pump 20 is automatically operated based on the action of the sensor, and the depositing material and the floating foreign matter are based on this operation. This is removed, and the water is removed together with the deposition material and the floating foreign matters to resume normal operation automatically, and the cleaning of the sump (10) is automatically performed.
