Description

Technical Field

[0001] The present application relates to the technical field of water filtration and treatment, and in particular to a horizontal net type sand and gravel filtration and treatment system for agricultural irrigation. Background Art

[0002] Agricultural irrigation uses sand and gravel filters mainly to effectively filter impurities and sand and gravel in water sources, protect irrigation systems and pipes from blockage and damage, improve irrigation efficiency, save water resources, adapt to a variety of water source conditions, and be easy to maintain and manage, ensuring the continuous and stable operation of agricultural irrigation systems.

[0003] The agricultural irrigation system in the prior art widely uses the horizontal net type sand and gravel filter, which is an advanced filtering equipment that combines the horizontal design with the mesh structure. It mainly uses quartz sand as the filtering medium, and through the dual filtering effect of the horizontal water flow and the mesh structure, it effectively intercepts and removes impurities such as suspended matter and particulate matter in the irrigation water, ensuring the cleanliness and transparency of the irrigation water. The horizontal net type sand and gravel filter is not only sturdy and durable in structure, and can withstand greater water flow pressure and impact force, but also has a backwashing function, which can automatically or manually remove blockages in the filter medium to maintain the filtering efficiency of the equipment.

[0004] Regarding the above-mentioned related technologies, the filtration effect of the sand and gravel filter in the prior art is relatively simple and cannot be adjusted according to actual needs. It only reverses the water flow for backwashing. The backwashing effect is relatively general, and the backwashing water flow size cannot be changed according to the real-time effect of backwashing, which wastes water resources. Summary of the invention

[0007] By adopting the above technical scheme, the three-way valve is adjusted to connect the sewage pipe and the water inlet pipe, the flushing pump and the sewage pump are opened in the positive direction, the flushing water and sewage are mixed in the sewage pipe, and then enter the sewage bin in the barrel body through the sewage pipe. Under the action of the flow equalization component on the water distribution plate, the sewage is evenly transported into the sand and gravel bin for filtration. The opening and closing mechanism in the present application can open and close the medium sand bin and the fine sand bin. When the medium sand bin and the fine sand bin are both closed, the sewage is filtered through the coarse sand bin in one layer. When only the fine sand bin is closed, the sewage is filtered through the coarse sand bin and the medium sand bin in two layers. When the medium sand bin and the fine sand bin are both opened, the sewage is filtered through the coarse sand bin, the medium sand bin and the fine sand bin in three layers.

[0009] By adopting the above technical scheme, the sewage pipe inputs mixed water of sewage and flushing water into the sewage tank, and the mixed water drives the flow equalizing fan to rotate when passing through the flow equalizing fan, and the rotation of the flow equalizing fan drives the rotating ring plate to rotate. Since a sliding block is provided on the side of the rotating ring plate close to the flow equalizing sheet, a sliding groove is provided on the flow equalizing sheet corresponding to the sliding block, and a moving block is provided on the side of the flow equalizing sheet close to the fixed ring plate, and a moving groove is provided on the fixed ring plate corresponding to the moving block. The projections of the moving groove and the sliding groove on the water distribution plate are arranged crosswise with each other, so when the rotating ring plate rotates, the channel area enclosed by multiple groups of flow equalizing sheets can be changed. The greater the flow rate of the mixed water, the smaller the channel area. By installing multiple groups of flow equalizing components, the sewage in the sewage tank can be evenly transported into the sand and gravel bin, avoiding the different degrees of use of sand and gravel at different positions in the sand and gravel bin due to excessive concentration of mixed water input into the sand and gravel bin, and improving the use effect and utilization rate of sand and gravel.

However, since the driving gear and the driven gear are engaged with each other, and one group of the multiple groups of second vibration rods penetrates the second fixed plate and is connected to the driven gear, the transmission wheels are respectively arranged on the ends of the multiple groups of first vibration rods and the multiple groups of second vibration rods, and the transmission wheels are connected and transmitted by belts. Therefore, the rotation of the driven gear can drive the self-rotation of the first vibration rod and the second vibration rod.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the sewage filtering effect is low, the driving component is not started, and the device only needs to be in the initial state. At this time, in the initial state, the first filter holes on the first fixed transverse plate and the first movable plate are staggered, the third filter holes on the first movable side plate and the fixed side plate are aligned, the second filter holes on the second fixed transverse plate and the second movable plate are staggered, and the fourth filter holes on the second movable side plate and the fixed side plate are aligned. After the sewage enters the sand and gravel bin, it can be filtered through the coarse sand bin and then flow into the bottom of the barrel body from the third filter hole; when the sewage needs to be further filtered, the driving component is started, and the first movable plate is driven alone to move toward the direction of the connecting pipe under the action of the driving component until the first fixed transverse plate and the first filter holes on the first movable plate are aligned, the first movable side plate and the third filter holes on the fixed side plate are staggered, and at the same time, the second fixed transverse plate and the second movable plate are aligned. The second filter holes are staggered, the fourth filter holes on the second movable side plate and the fixed side plate are aligned, and the sewage is filtered through two layers of the coarse sand bin and the medium sand bin before flowing into the bottom of the barrel body from the fourth filter hole; when it is necessary to filter the sewage deeply, continue to start the driving assembly, and the driving assembly simultaneously drives the first movable plate and the second movable plate to move in the direction of the connecting pipe until the first fixed horizontal plate and the first filter hole on the first movable plate are aligned, the second fixed horizontal plate and the second filter hole on the second movable plate are aligned, the third filter hole on the first movable side plate and the fixed side plate are staggered, and the fourth filter hole on the second movable side plate and the fixed side plate are staggered, and the sewage is filtered through three layers of the coarse sand bin, the medium sand bin and the fine sand bin and directly enters the bottom of the barrel body, thereby realizing the opening and closing of the medium sand bin and the fine sand bin, and realizing the selection of different filtering effects and improving the filtering efficiency according to actual usage needs; 2. After the laser emitted by the laser transmitter passes through the backwash water of the sewage tank, the light intensity may be reduced due to the impurities in the backwash water. Therefore, the backwash effect on the sand and gravel can be judged according to the light intensity received by the light intensity sensor. The stronger the detected light intensity, the fewer impurities in the backwash water, the lower the rate of flushing water input into the barrel through the outlet pipe by the flushing pump, and the lower the light intensity received by the light intensity sensor, the higher the rate of flushing water input into the barrel through the outlet pipe by the flushing pump. While ensuring efficient flushing of sand and gravel, the utilization rate of backwash water is also improved, reducing the waste of water resources; 3. The sewage pipe inputs the mixed water of sewage and flushing water into the sewage tank. When the mixed water passes through the flow equalizing fan, it will drive the flow equalizing fan to rotate. The rotation of the flow equalizing fan drives the rotating ring plate to rotate. Since a sliding block is arranged on the side of the rotating ring plate close to the flow equalizing sheet, a sliding groove is provided on the flow equalizing sheet corresponding to the sliding block, and a moving block is arranged on the side of the flow equalizing sheet close to the fixed ring plate, and a moving groove is provided on the fixed ring plate corresponding to the moving block. The projections of the moving groove and the sliding groove on the water distribution plate are arranged crosswise with each other, so when the rotating ring plate rotates, the channel area surrounded by multiple groups of flow equalizing sheets can be changed. When the flow rate of the mixed water is greater, the channel area is smaller. By installing multiple groups of flow equalizing components, the sewage in the sewage tank can be evenly transported into the sand and gravel bin, avoiding the excessive concentration of mixed water input into the sand and gravel bin, resulting in different use levels of sand and gravel at different positions in the sand and gravel bin, and improving the use effect and utilization rate of sand and gravel; 4. Start the driving motor in the forward direction. When the output shaft of the driving motor rotates in the forward direction, the ratchet and the pawl mesh with each other to drive the rotation of the rotating disk. After the opening and closing of the medium sand bin and the fine sand bin are completed according to the actual filtering needs, start the driving motor in the reverse direction. When the output shaft of the driving motor rotates in the reverse direction, the ratchet and the pawl do not mesh, and the rotating disk remains stationary. However, since the driving gear and the driven gear mesh with each other, and one of the multiple sets of second vibration rods penetrates the second fixed plate and is connected to the driven gear, the transmission wheels are respectively arranged on the ends of the multiple sets of first vibration rods and the multiple sets of second vibration rods, and the transmission wheels are connected and transmitted by belts. Therefore, the rotation of the driven gear can drive the self-rotation of the first vibration rod and the second vibration rod. Because the first vibration rod and the second vibration rod are unevenly provided with protrusions, the first vibration rod and the second vibration rod will vibrate when they rotate, thereby vibrating the medium sand and the fine sand, thereby reducing impurities attached to the medium sand and the fine sand, and further improving the flushing effect of the medium sand and the fine sand. The air pump inputs gas to the bottom of the barrel body through the air inlet pipe. Under the dual action of gas and backwashing water, the flushing effect and flushing efficiency of the sand and gravel in the barrel body can be further improved, and the amount of flushing water consumed during backwashing can be further reduced.

A vibration component 4 for vibrating the medium sand and the fine sand during backwashing is arranged in the medium sand bin 272 and the fine sand bin 273. A detection component 5 for detecting the cleanliness of the water in the sewage bin 26 during backwashing is arranged in the sewage bin 26, so as to automatically adjust the speed of the backwashing water input into the water outlet pipe 28; A first fixed plate 6 and a second fixed plate 7 are respectively provided at both ends of the barrel body 2. The coarse sand bin 271, the medium sand bin 272 and the fine sand bin 273 are all arranged between the first fixed plate 6 and the second fixed plate 7. The first fixed plate 6 is arranged close to the connecting pipe 24, and the second fixed plate 7 is arranged close to the water outlet pipe 28. The connecting pipe 24 is connected to a side of the first fixed plate 6 close to the second fixed plate 7, and the water outlet pipe 28 is connected to a side of the second fixed plate 7 close to the first fixed plate 6. The first fixed plate 6 and the second fixed plate 7 are provided with an opening and closing mechanism 8 for opening and closing the medium sand bin 272 and the fine sand bin 273 respectively to achieve different filtering effects on sewage.

[0030] Adjust the three-way valve 22 to connect the sewage pipe 21 and the water inlet pipe 23, open the flushing pump 53 and the sewage pump 221 in the forward direction, mix the flushing water and sewage in the sewage pipe 21, and then enter the sewage tank 26 in the barrel 2 through the sewage pipe 21.

When the medium sand bin 272 and the fine sand bin 273 are both closed, When the sewage is filtered through the coarse sand bin 271, the sewage is filtered through the coarse sand bin 271 and the medium sand bin 272. When the medium sand bin 272 and the fine sand bin 273 are both opened, the sewage is filtered through the coarse sand bin 271, the medium sand bin 272 and the fine sand bin 273. In this way, different filtering effects can be selected according to actual usage requirements and the filtering efficiency can be improved. When the sand and gravel in the barrel body 2 need to be backwashed, the opening and closing mechanism 8 is used to filter the sewage. Open both the medium sand bin 272 and the fine sand bin 273, and then connect the water inlet pipe 23 and the connecting pipe 24 by adjusting the three-way valve 22, open the flushing pump 53 in the forward direction and the sewage pump 221 in the reverse direction, and the flushing water enters the barrel body 2 through the connecting pipe 24. As the amount of flushing water in the barrel body 2 increases, the flushing water can backwash the impurities filtered by the sand and gravel in the coarse sand bin 271, the medium sand bin 272 and the fine sand bin 273, and the flushing water carries the impurities and is output from the sewage pipe 21, thereby ensuring the filtering effect of the device on the sewage. During backwashing, the vibration component 4 in the present application can vibrate the medium sand and fine sand, thereby reducing the impurities attached to the medium sand and fine sand, and further improving the flushing effect of the medium sand and fine sand. The detection component 5 in the present application can detect the cleanliness of the sewage in the sewage bin 26, and adjust the speed of the backwashing water input into the outlet pipe 28 according to the detection result.

[0031] Reference Figure 2 and Figure 3The flow balancing component 3 includes a fixed ring 31, a flow balancing fan 32, a rotating ring plate 33, a flow balancing sheet 34, a fixed ring plate 35 and a reset member 36. The fixed ring 31 penetrates the water distribution plate 25 and is arranged on the water distribution plate 25. The flow balancing fan 32 is rotatably arranged in the fixed ring 31. The rotating ring plate 33 is rotatably arranged in the fixed ring 31 and is connected to the side of the flow balancing fan 32 away from the sewage pipe 21. The fixed ring plate 35 is arranged in the fixed ring 31 and is located on the side of the rotating ring plate 33 away from the flow balancing fan 32. There are multiple groups of flow balancing sheets 34, and the multiple groups of flow balancing sheets 34 are movably arranged on the rotating ring plate 33 and Between the fixed ring plates 35, a sliding block 331 is provided on the side of the rotating ring plate 33 close to the current balancing plate 34, and a sliding groove 341 is provided on the current balancing plate 34 corresponding to the sliding block 331. A moving block 342 is provided on the side of the current balancing plate 34 close to the fixed ring plate 35, and a moving groove 351 is provided on the fixed ring plate 35 corresponding to the moving block 342. The projections of the moving groove 351 and the sliding groove 341 on the water distribution plate 25 are arranged crosswise with each other. A reset member 36 is arranged between the fixed ring 31 and the rotating ring plate 33, and is used to reset the current balancing fan 32. In this embodiment, the reset member 36 is a torsion spring.

[0032] The sewage pipe 21 inputs the mixed water of sewage and flushing water into the sewage tank 26. When the mixed water passes through the flow balancing fan 32, it drives the flow balancing fan 32 to rotate. The rotation of the flow balancing fan 32 drives the rotating ring plate 33 to rotate. Since the rotating ring plate 33 is provided with a sliding block 331 on the side close to the flow balancing sheet 34, the flow balancing sheet 34 is provided with a sliding groove 341 corresponding to the sliding block 331, and the flow balancing sheet 34 is provided with a moving block 342 on the side close to the fixed ring plate 35, and the fixed ring plate 35 is provided with a moving groove 351 corresponding to the moving block 342, the moving ring plate 35 is provided with a moving block 342. The projections of the groove 351 and the sliding groove 341 on the water distribution plate 25 are arranged to cross each other, so when the rotating ring plate 33 rotates, the channel area enclosed by the multiple groups of flow equalizing plates 34 can be changed. When the flow rate of the mixed water is greater, the channel area is smaller. By installing multiple groups of flow equalizing components 3, the sewage in the sewage tank 26 can be evenly transported into the sand and gravel tank 27, avoiding excessive concentration of mixed water input into the sand and gravel tank 27, resulting in different degrees of use of sand and gravel at different positions in the sand and gravel tank 27, and improving the use effect and utilization rate of sand and gravel.

[0033] Reference Figure 2 The detection component 5 includes a laser emitter 51 and a light intensity sensor 52. The laser emitter 51 and the light intensity sensor 52 are spaced and relatively arranged in the sewage tank 26. The light intensity sensor 52 is used to receive the light output by the laser emitter 51. A flushing pump 53 is arranged on the water inlet pipe 23. The flushing pump 53 is electrically connected to the light intensity sensor 52. The higher the light intensity received by the light intensity sensor 52, the lower the flushing water rate input into the barrel body 2 by the flushing pump 53 through the water inlet pipe 23. The lower the light intensity received by the light intensity sensor 52, the higher the flushing water rate input into the barrel body 2 by the flushing pump 53 through the water inlet pipe 23.

[0034] After the laser emitted by the laser transmitter 51 passes through the backwash water of the sewage tank 26, the light intensity may be reduced due to the impurities contained in the backwash water. Therefore, the backwash effect on the sand and gravel can be judged according to the light intensity received by the light intensity sensor 52. The stronger the detected light intensity, the fewer impurities in the backwash water, and the lower the rate of flushing water input into the barrel body 2 by the flushing pump 53 through the outlet pipe 28. The lower the light intensity received by the light intensity sensor 52, the higher the rate of flushing water input into the barrel body 2 by the flushing pump 53 through the outlet pipe 28. While ensuring efficient flushing of sand and gravel, the utilization rate of backwash water is also improved, reducing the waste of water resources.

When the sand and gravel in the barrel body 2 need to be backwashed, the opening and closing mechanism 8 is used to filter the sewage. Open both the medium sand bin 272 and the fine sand bin 273, and then connect the water inlet pipe 23 and the connecting pipe 24 by adjusting the three-way valve 22, open the flushing pump 53 in the forward direction and the sewage pump 221 in the reverse direction, and the flushing water enters the barrel body 2 through the connecting pipe 24. As the amount of flushing water in the barrel body 2 increases, the flushing water can backwash the impurities filtered by the sand and gravel in the coarse sand bin 271, the medium sand bin 272 and the fine sand bin 273, and the flushing water carries the impurities and is output from the sewage pipe 21, thereby ensuring the filtering effect of the device on the sewage. During backwashing, the vibration component 4 in the present application can vibrate the medium sand and fine sand, thereby reducing the impurities attached to the medium sand and fine sand, and further improving the flushing effect of the medium sand and fine sand. The detection component 5 in the present application can detect the cleanliness of the sewage in the sewage bin 26, and adjust the speed of the backwashing water input into the outlet pipe 28 according to the detection result. While ensuring the efficient flushing of the sand and gravel, the utilization rate of the backwashing water is also improved, and the waste of water resources is reduced.
