Description

MULTIFUNCTIONAL STORAGE TANK FOR SECURING FIELD IRRIGATION WATER}

The present invention relates to a multifunctional storage tank for securing field water, and more particularly, to a multifunctional storage tank for securing field water with a water quality improvement function and a water temperature maintaining function so that surface water can be used as field irrigation water.

In recent years, due to the increase of farmers who want to grow other crops and grow high-income crops, facility farming has increased considerably. In order to grow high-income eco-friendly agricultural products, the supply of clean and healthy water is important. In addition, the demand for eco-friendly agricultural products continues to increase due to food safety incidents, media reports, and increased consumer interest in family health.

Meanwhile, the incidence and intensity of droughts due to abnormal weather have increased significantly. The low yields in most regions of the country are rapidly falling due to the heat wave in summer and the shortage of precipitation from May to June. The drought has been a growing concern for drought.

In particular, it is urgent to take measures to reduce direct effects and losses such as deterioration of field crops and unstable supply and demand of crops during drought, and it is necessary to secure adequate water considering the characteristics of the field area in order to produce high quality field crops.

In the past, interest in field waters was low due to the development of agricultural water supply facilities centered on reservoirs and pumping stations for paddy water supply.However, due to climate change, existing cropland water management and drought management have technical limitations. It is urgent to improve the supply facilities for agricultural water in Korea.

In addition, the field crop cultivation area in the paddy field is increasing, and due to the rice paddy-based water supply system despite the water in the reservoir, it is impossible to supply water to the general field in case of severe drought.

By using extra surface water due to the reduction of paddy area as field irrigation water, the multipurpose use of agricultural water is needed to improve the utilization of existing repair facilities, reduce the use of agricultural water, and save new development costs.

In addition, agricultural water is usually taken from reservoirs or rivers and supplied through concrete or earthworks. Due to its characteristics, it is inadequate to be applied to water equipment that incorporates advanced agricultural technologies, such as nutrient irrigation and drip irrigation, which are frequently exposed to pollutants due to the inflow of suspended solids and easily exposed to pollutants. This is necessary.

In particular, in areas with severe water pollution, many difficulties arise in improving the water quality of facilities, such as the installation and operation of a simple water purification plant. Since the existing water treatment method is costly, the competitiveness is inferior, thus producing high quality eco-friendly agricultural products. The development of such a low cost facility water supply system is urgently needed.

In addition, winter irrigation for facility horticultural crops or winter crops is necessary to prevent the rise of water temperature of the plant cultivation crops due to water irrigation, such as winter low water temperature due to the weather conditions in Korea.

Facility Cultivation Agriculture is a plant that is needed for cultivation regardless of the season. Therefore, when water is transported using existing water harvesting in winter, the water in the channel is frozen and cannot be used as a water supply facility to supply water to field crops. In addition, cold water may not only cause cold damage to field crops, but it is also inefficient to manage water sources and water for supplying water to small-scale field crop cultivation complexes. Therefore, in order to irrigate not only the agricultural facility in winter but also general field irrigation, the water supply and drainage facilities from the water source to the facility agricultural complex should be buried to a depth below freezing depth to prevent freezing or low temperature during the water supply process. In addition, measures to prevent low water temperature are needed in reservoirs that can store water as well as water and drainage facilities.

The present applicant has proposed the present invention to solve the above problems.

Figure 1 schematically shows a multi-functional storage tank (100, hereinafter referred to as "multi-functional storage tank") for securing field water according to an embodiment of the present invention.

Referring to FIG. 1, in the multifunctional storage tank 100 according to an exemplary embodiment of the present invention, a sedimentation tank 110 and a treatment water tank 160 are respectively formed in the body 101. An air vent (not shown) may be formed in the roof of the main body 101 to discharge air generated in the main body 101 or existing in the main body 101 to the outside.

The body 101 is preferably formed to a sufficient size to store the water, it is preferable that the treatment tank 160 is formed to have a larger capacity than the precipitation tank 110.

The main body 101 is preferably formed on the indicator E, and flow paths 104, 105, 106, 107 and 132 through which water flows in and out may be formed at the lower end of the main body 101.

The sedimentation tank 110 and the treatment water tank 160 are divided into partitions 103, and the lower end of the partition 103 is connected to the bottom surface of the main body 101, but the upper end of the partition 103 is a roof of the main body 101. It is preferably formed so as not to be connected to.

The energy supply unit 190 may be formed at one side of the main body 101. The energy supply unit 190 may supply electrical energy required by the multifunctional storage tank 100. Here, the energy supply unit 190 is a renewable energy supply unit for generating electrical energy using sunlight or wind.

The energy supply unit 190 may include a pillar member 191, a wind power generation module 196 formed on the pillar member 191, and a solar power generation module 194. Electrical energy obtained from the wind power generation module 196 and the solar power generation module 194 may be stored in the energy storage unit 192 provided at the lower end of the pillar member 191.

The energy storage unit 192 may include a generator (not shown) that directly produces electrical energy, or may include a battery (not shown) that stores the produced electrical energy. Here, the battery may be formed as a secondary battery capable of charging and discharging or may be formed as an energy storage system.

The electrical energy obtained by the energy supply unit 190 may be used as a power source such as various pumps of the multifunctional storage tank 100. As such, the multifunctional storage tank 100 according to the embodiment of the present invention is installed in a place where general electric energy is not supplied because it has an energy supply unit 190 for producing electric energy using wind or solar light. Can be used. That is, the multifunctional storage tank 100 according to an embodiment of the present invention can be installed without regard to the place.

Hereinafter, with reference to the drawings, the structure and operation of the multifunctional storage tank 100 according to an embodiment of the present invention will be described.

2 to 6, the multifunctional storage tank 100 according to an embodiment of the present invention, the sedimentation tank 110, the sedimentation tank for depositing the groundwater or surface water is stored and precipitates the contaminants present in the groundwater or surface water The treatment unit 160 is provided on one side of the processing water tank 160 to store the treated water from which the contaminant is removed from the groundwater or surface water, and the treatment water tank 160 and controls or maintains the temperature of the treated water. And a filtering unit 140 disposed in the treatment tank 160 to remove the contaminants not precipitated in the sedimentation tank 110 among the contaminants present in the ground water or the surface water to discharge the treated water.

As described above, the multifunctional storage tank 100 according to an embodiment of the present invention precipitates the pollutants having a relatively large particle size in the sedimentation tank 110 and the sedimentation tank 110 in which ground water or surface water is primarily stored. It may include a treated water tank 160 to be purified by flowing ground water or surface water. That is, the groundwater or surface water is stored in the sedimentation tank 110 for a predetermined time and then sent to the treatment water tank 160.

The settling tank 110 is a tank that sinks contaminants having a relatively large particle size among contaminants present in groundwater or surface water. Since the contaminants of the relatively large particles may damage the filters 141 and 142 of the filtration unit 140, which will be described later, the contaminants of the relatively large particles before the groundwater or surface water is sent to the filtration unit 140 are settled. Should be removed from

If a certain amount of the sedimentary pollutants are accumulated sitting on the bottom of the settling tank 110, the operator can develop a door 102 provided on the upper portion of the body 101 and enter the sedimentation tank 110 to remove the sedimented pollutants. . For this operation, the settling tank 110 is preferably provided with a ladder (not shown) so that the worker can access the floor. Before removing the contaminants deposited in the settling tank 110, it is preferable to completely send the ground water or surface water of the settling tank 110 to the treated water tank (160).

The groundwater or surface water may be introduced into the settling tank 110 by a supply pump 121 provided on the outside or one side of the settling tank 110. The ground water may be withdrawn from the well (not shown) and then sent to the settling tank 110 by the supply pump 121. In addition, surface water, such as reservoirs and rivers, may be sent to the settling tank 110 by the supply pump 121.

Multifunctional storage tank 100 according to an embodiment of the present invention is preferably installed in a high zone so that water discharged by natural oil, that is, the altitude difference flows into the field. Therefore, in order to pull groundwater or surface water to a high zone and send it to the settling tank 110, a supply pump 121 is required.

Here, the supply pump 121 may be operated by receiving the electrical energy from the energy supply unit 190.

A settling tank inlet pipe 122 may be formed between the settling tank 110 and the supply pump 121. The settling tank inlet pipe 122 is a pipe or tube connecting the settling tank 110 and the supply pump 121. Precipitation tank inlet pipe 122 is preferably connected to the lower side of the precipitation tank (110).

On the other hand, in the sedimentation tank 110, an inflow pump 131 for transmitting the ground water or surface water to the filter unit 140 may be provided. Inflow pump 131 is preferably provided on the bottom side of the sedimentation tank 110 to be immersed in groundwater or surface water stored in the sedimentation tank 110. In this case, a first frame 139 (see FIG. 3) for supporting the inflow pump 131 may be provided at the bottom of the settling tank 110. The first frame 139 is a structure in which the inflow pump 131 does not directly contact the bottom of the settling tank 110.

It is preferable that a gap is maintained between the first frame 139 and the bottom of the settling tank 110. In this case, groundwater or surface water existing between the first frame 139 and the bottom of the settling tank 110 may be sent to the filtration unit 140 by the inflow pump 131.

On the other hand, the sedimentation tank 110 may be formed with a first level detection unit 111 for detecting the water level or the quantity of the ground water or surface water stored in the sedimentation tank 110. The first water level detection unit 111 may be formed of a water level sensor or a water quantity sensor, and is preferably disposed long along the height direction of the precipitation tank 110.

The operation of the supply pump 121 may be determined according to the level or quantity of groundwater or surface water detected by the first water level detection unit 111. For example, when the first water level detecting unit 111 detects the lowest water level or quantity, the supply pump 121 may operate to introduce groundwater or surface water into the settling tank 110. On the other hand, when the first water level detecting unit 111 detects the maximum water level or quantity, the operation of the supply pump 121 may be stopped to prevent groundwater or surface water from flowing into the sedimentation tank 110 anymore. In addition, when the first water level detecting unit 111 detects the maximum water level or quantity, the inflow pump 131 may operate to send the groundwater or surface water of the sedimentation tank 110 to the treatment water tank 160.

The inflow pump 131 sends the groundwater or surface water from which the sediment contaminants are first removed from the sedimentation tank 110 to the filtration unit 140, so that small particles of contaminants not precipitated in the sedimentation tank 110 are filtered. ) Can be removed.

Meanwhile, the filtration unit 140 provided in the treatment water tank 160 includes at least one filter 141 and 142 connected to the inflow pump 131 and into which groundwater or surface water flows, and the filters 141 and 142 in groundwater or surface water. After removing the contaminants, the treated water may be discharged to the treated water tank 160.

The filtration unit 140 preferably includes two filters 141 and 142. The inflow pump 131 and the filters 141 and 142 may be connected to each other by the main inlet pipe 132 and the branch inlet pipes 133a and 133b. The main inlet pipe 132 is a pipe or tube whose one end is connected to the inlet pump 131 to send groundwater or surface water discharged from the inlet pump 131 toward the filters 141 and 142. The other end of the main inlet pipe 132 may be connected to two branch pipes, that is, branch inlet pipes 133a and 133b. Branch inflow pipes 133a and 133b are connected to one filter 141 and 142, respectively, and may send groundwater or surface water to the filters 141 and 142.

Small contaminants contained in groundwater or surface water may be filtered out of filters 141 and 142. Groundwater or surface water from which small-sized contaminants have been removed from the filters 141 and 142 may be discharged directly through the sides of the filters 141 and 142. In other words, since the branch inflow pipes 133a and 133b are connected to the upper center portions of the filters 141 and 142, groundwater or surface water flows into the inner portions of the filters 141 and 142, whereas the treated water from which the pollutants are removed is filtered ( 141, 142 may be discharged through the side or the outer peripheral surface. The treated water discharged from the filters 141 and 142 freely falls toward the treated water tank 160.

The filter unit 140 to the filter (141, 142) is preferably provided on the upper side of the treatment tank (160). That is, the filtration unit 140 to the filter (141, 142) is preferably provided at a position or height that is not submerged in the treated water even if the treated water stored in the treated water tank 160 reaches the maximum level.

As the inlet pump 131 operates, many small particles of contaminants may be caught or adsorbed to the filters 141 and 142. If the pollutant adsorbed increases, the filters 141 and 142 may not function properly. Therefore, in order for the filters 141 and 142 to function normally, the filters need to be replaced or cleaned.

Instead of replacing the filter, the multifunctional storage tank 100 according to an embodiment of the present invention adopts a method of washing the filters 141 and 142. That is, by cleaning the filters 141 and 142 at regular or regular time intervals in order to remove the contaminants adsorbed or filtered from the filters 141 and 142 from the filters 141 and 142, the performance of the filters 141 and 142 can be maintained for a long time without replacing the filters. have. As described above, the multifunctional storage tank 100 according to the embodiment of the present invention filters the filters 141 and 142 at regular time intervals in order to prevent the filters 141 and 142 from being blocked by contaminants contained in groundwater or surface water passing through the settling tank 110. ) Can be cleaned. In this case, the filters 141 and 142 may be washed using the treated water stored in the treated water tank 160.

The treated water tank 160 is provided with a backwash pump 151 for washing the filters 141 and 142 using the treated water, and the treated water discharged from the filters 141 and 142 after washing the filters 141 and 142 is a settling tank 110. Can be sent to.

Referring to FIG. 3, the backwash pump 151 may be provided at the bottom of the treatment tank 160 so as to be immersed in the treatment water stored in the treatment tank 160. In this case, a second frame 159 (see FIG. 3) for supporting the backwash pump 151 may be provided at the bottom of the treatment tank 160. The second frame 159 is a structure in which the backwash pump 151 does not directly contact the bottom of the treatment tank 160.

It is preferable that a gap is maintained between the second frame 159 and the bottom of the treatment tank 160. In this case, the treatment water existing between the second frame 159 and the bottom of the treatment tank 160 may also be sent to the filters 141 and 142 by the backwash pump 151. That is, even when the water level of the treated water stored in the treated water tank 160 is not high, the filters 141 and 142 may be washed using the treated water.

When the backwash pump 151 washes the filters 141 and 142 using the treated water from which contaminants have been removed, the ground water or the surface water flows the treated water in the opposite direction, that is, in the opposite direction to the flow processed through the filters 141 and 142. The filters 141 and 142 may be cleaned.

The backwash pump 151 may be connected with a backwash water inlet pipe 152. The backwash water inlet pipe 152 is one pipe or tube whose one end is connected to the backwash pump 151. The other end of the backwash water inlet pipe 152 may be connected to the backwash water branch pipes 153a and 153b.

The backwash branch pipes 153a and 153b may be connected to the side surfaces or the outer circumferential surface of the filters 141 and 142, respectively. Here, it is preferable that at least two branch pipes are connected to the side or outer peripheral surface of the filters 141 and 142 with respect to the filters 141 and 142 in the backwash water branch pipes 153a and 153b.

When the filters 141 and 142 function to remove the contaminants in the ground or surface water, the treated water from which the contaminants have been removed is discharged through the sides of the filters 141 and 142. It can be adsorbed inside the side. As described above, in order to remove the contaminants adsorbed on the inner side of the filters 141 and 142, it is necessary to supply the washing water from the outer side of the filters 141 and 142 to the inner side. Therefore, the backwash branch pipes 153a and 153b are connected to the side surfaces or the outer circumferential surfaces of the filters 141 and 142, respectively, to supply the treated water from the outside of the side surfaces to the inside.

When the filters 141 and 142 operate normally, the direction of water flow is reversed when the filters 141 and 142 are washed. This water flow direction may be formed by the backwash pump 151.

The backwashing water washed with the filters 141 and 142 may be discharged through the lower center portion of the filters 141 and 142. That is, the backwashing water (treated water) introduced through the side surfaces of the filters 141 and 142 may be discharged through the lower center portions of the filters 141 and 142 after removing the contaminants adsorbed on the inner sides of the filters 141 and 142.

As described above, the ground water or the surface water supplied by the inflow pump 131 (the upper center portion of the filter) flowing into the filters 141 and 142, and the filter 141 and 142 after washing the filter 141 and 142 by the backwash pump 151 Portions (side of the filter) where the water flows out of the filters 141 and 142 may be formed at different portions of the filters 141 and 142, respectively.

Meanwhile, since the backwash water flowing out of the filters 141 and 142 includes contaminants, the treated water and the outflow backwash water stored in the treatment tank 160 should not be mixed. To this end, the backwash water outlet branch pipes 134a and 134b may be formed in the lower center portion of the filters 141 and 142, respectively. The backwash water outlet pipes 134a and 134b are pipes or tubes connected to the bottom center of each filter 141 and 142. The backwash water outlet branch pipes 134a and 134b may be connected to one backwash water outlet pipe 135 and 136.

The backwash water outlet pipes 135 and 136 are pipes or tubes connected to the backwash water outlet pipes 134a and 134b. The backwash water flowing through the backwash water outlet branch pipes 134a and 134b and the backwash water outlet pipes 135 and 136 contains contaminants, so that the backwash water separately provided in the treated water tank 160 is not mixed with the treated water and the outflow backwash water. The outflowing backwash water should be discharged to the outside of the treatment tank 160 through the outflow branch pipes 134a and 134b and the backwash water outflow pipes 135 and 136.

As described above, the effluent backwash water that is washed and discharged through the filters 141 and 142 may not be discharged to the outside of the multifunctional storage tank 100 because pollutants are included. Multifunctional storage tank 100 according to an embodiment of the present invention can be sent to the settling tank 110 to send backwash water containing contaminants to recycle. Thus, the backwash water outlet pipes 135 and 136 may be connected to the settling tank 110.

Meanwhile, an opening / closing valve 137 may be formed in the flow paths 135 and 136 provided to allow the treated water (reverse washing water) discharged from the filters 141 and 142 to flow into the settling tank 110 after washing the filters 141 and 142.

The backwash pump 151 should not operate while the inflow pump 131 operates and the groundwater or surface water flows into the treatment tank 160. This is because the inflow pump 131 has groundwater or surface water flowing into the filters 141 and 142 and the backwash pump 151 has the opposite direction in which the treated water flows into the filters 141 and 142. And while the backwash pump 151 is in operation, the other should not be in operation.

The on-off valve 137 may be opened when the backwash pump 151 operates, and may be closed when the backwash pump 151 stops. That is, the on-off valve 137 is installed in the backwash water outlet pipes 135 and 172 to open the backwash water outlet pipes 135 and 172 only when the backwash pump 151 operates, and when the backwash pump 151 does not operate, It is a valve which closes the wash water outlet pipes 135 and 172.

In addition, when the backwash pump 151 is not operated, the backwash water outlet pipes 135 and 172 are closed by the on / off valve 137 to prevent the purified water from being supplied to the field but not flowing into the settling tank 110. have.

The on-off valve 137 is preferably controlled to open and close by the operation of the solenoid.

On the other hand, the treatment tank 160 may be formed with a second water level detection unit 161 for detecting the level or quantity of the treated water. Similar to the first water level detection unit 111, the second water level detection unit 161 may be formed as a water level sensor or a water level sensor, and is preferably disposed long along the height direction of the treatment tank 160.

The operation of the inflow pump 131 or the backwash pump 151 may be determined according to the level or quantity of the treated water detected by the second water level detection unit 161. For example, when the second water level detection unit 161 detects the minimum water level or quantity, the inflow pump 131 may operate to introduce the treated water into the treated water tank 160. On the other hand, when the second water level detection unit 161 detects the maximum water level or quantity, the operation of the inflow pump 131 may be stopped to prevent the treated water from flowing into the treatment tank 160 any more. In addition, when the second water level detecting unit 161 detects the maximum water level or quantity, the backwash pump 151 may operate to clean the filters 141 and 142. As such, the inflow pump 131 or the backwash pump 151 may operate according to the water level or quantity of the treated water detected by the second water level sensing unit 161.

The multifunctional storage tank 100 according to an embodiment of the present invention may maintain the water temperature of the treated water, and may adjust the water temperature so that the treated water does not freeze in winter. To this end, the main body 101 of the storage tank 100 may be formed of a heat insulating material, or a heating wire may be installed inside the main body 101.

In addition, in order to directly control the water temperature of the treated water, the heater 171 may be formed in the treated water tank 160. The heater 171 may adjust or control the water temperature of the treated water by generating heat by receiving electric energy. The heater 171 may receive electric energy from the energy supply 190.

The heater unit 171 is preferably provided on the lower side of the treatment tank (160).
