Description

Technical Field

[0001] This application relates to the technical field of water filtration treatment, and particularly to an agricultural irrigation horizontal net-type sand and gravel filtration treatment system. Background Art

[0002] When agricultural irrigation uses sand and gravel filters, it is mainly to effectively filter impurities and sand and gravel in the water source, protect the irrigation system and pipelines from blockage and damage, improve irrigation efficiency, save water resources, adapt to various water source conditions, and is easy to maintain and manage to ensure the continuous and stable operation of the agricultural irrigation system.

[0003] In the prior art, horizontal net-type sand and gravel filters are widely used in agricultural irrigation systems. This is an advanced filtering device that combines a horizontal design and a mesh structure. It mainly uses quartz sand as the filtering medium, and through the dual filtering effects of horizontal water flow and mesh structure, effectively intercepts and removes impurities such as suspended solids and particulate matter in the irrigation water, ensuring the cleanliness and transparency of the irrigation water. The horizontal net-type sand and gravel filter not only has a strong and durable structure, can withstand large water flow pressures and impact forces, but also has an anti-flushing function, which can automatically or manually remove blockages in the filtering medium and maintain the filtering efficiency of the device.

[0004] For the above related technologies, the filtering effect of the sand and gravel filter in the prior art is relatively single, cannot be adjusted according to actual needs, and only backwashes by reverse water flow. The backwashing effect is relatively average, and the water flow size of the backwashing cannot be changed according to the real-time effect of the backwashing, which is relatively wasteful of water resources. Summary of the Invention

[0005] In order to enable the sand and gravel filter to be adjusted according to actual usage requirements and reduce the waste of water resources while ensuring the backwashing efficiency, this application provides an agricultural irrigation horizontal net-type sand and gravel filtration treatment system.

[0006] An agricultural irrigation horizontal net-type sand and gravel filtration treatment system provided by this application adopts the following technical solutions:

[0007] An agricultural irrigation horizontal net-type sand and gravel filtration treatment system, comprising a mounting seat and a barrel body. The barrel body is arranged on the mounting seat. A sewage pipe is arranged on the barrel body. A sewage pump is arranged on the sewage pipe. A three-way valve is arranged on the sewage pipe. The sewage pipe is connected to one valve port of the three-way valve. A water inlet pipe and a connecting pipe are respectively arranged on the other two valve ports of the three-way valve. One end of the connecting pipe away from the three-way valve is connected to the barrel body. A water distribution plate is arranged inside the barrel body. The water distribution plate is arranged below the connection part of the sewage pipe and the barrel body. The water distribution plate divides the space inside the barrel body into a sewage chamber and a sand and gravel chamber. Multiple groups of flow equalizing components for evenly conveying the sewage in the sewage chamber into the sand and gravel chamber are arranged on the water distribution plate;

[0008] A coarse sand chamber, a medium sand chamber and a fine sand chamber are arranged inside the sand and gravel chamber. Coarse sand is placed in the coarse sand chamber, medium sand is placed in the medium sand chamber, and fine sand is placed in the fine sand chamber. Filter holes with different diameters are opened on the bottom plates of the coarse sand chamber, the medium sand chamber and the fine sand chamber. The coarse sand chamber is arranged below the water distribution plate, the fine sand chamber is arranged below the coarse sand chamber, and the medium sand chamber is arranged between the coarse sand chamber and the fine sand chamber. An outlet pipe for outputting the filtered sewage is arranged on the barrel body. An opening and closing valve is arranged on the outlet pipe. A vibration component for vibrating the medium sand and the fine sand during backwashing is arranged inside the medium sand chamber and the fine sand chamber. A detection component for detecting the cleanliness of the water in the sewage chamber during backwashing so as to automatically adjust the input speed of the backwashing water of the water inlet pipe is arranged inside the sewage chamber;

[0009] First fixing plates and second fixing plates are respectively arranged at both ends inside the barrel body. The coarse sand chamber, the medium sand chamber and the fine sand chamber are all arranged between the first fixing plate and the second fixing plate. And the first fixing plate is arranged close to the connecting pipe, and the second fixing plate is arranged close to the outlet pipe. The connecting pipe is communicated with one side of the first fixing plate close to the second fixing plate, and the outlet pipe is communicated with one side of the second fixing plate close to the first fixing plate. An opening and closing mechanism for respectively opening and closing the medium sand chamber and the fine sand chamber to achieve different filtration effects on sewage is arranged on the first fixing plate and the second fixing plate.

[0010] By adopting the above technical solution, 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 forward, and the flushing water and the sewage are mixed in the sewage pipe and then enter the sewage storage bin in the barrel through the sewage pipe. Under the action of the flow equalizing component on the water distribution plate, the sewage is evenly transported into the sand storage bin for filtration. The opening and closing mechanism in this application can open and close the medium sand bin and the fine sand bin. When both the medium sand bin and the fine sand bin are closed, the sewage is filtered once through the coarse sand bin. When only the fine sand bin is closed, the sewage is filtered twice through the coarse sand bin and the medium sand bin. When both the medium sand bin and the fine sand bin are opened, the sewage is filtered three times through the coarse sand bin, the medium sand bin and the fine sand bin. In this way, different filtration effects can be selected according to actual usage requirements and the filtration efficiency can be improved. When it is necessary to backwash the sand in the barrel, the medium sand bin and the fine sand bin are both opened through the opening and closing mechanism, and then the three-way valve is adjusted to connect the water inlet pipe and the connecting pipe. The flushing pump is opened forward and the sewage pump is opened backward. The flushing water enters the barrel through the connecting pipe. As the amount of flushing water in the barrel increases, the flushing water can backwash the impurities filtered by the sand in the coarse sand bin, the medium sand bin and the fine sand bin. The flushing water carries the impurities and is output from the sewage pipe, so as to ensure the filtration effect of the device on the sewage. During backwashing, the vibration component in this application can vibrate the medium sand and the fine sand, so as to reduce the impurities attached to the medium sand and the fine sand and further improve the backwashing effect on the medium sand and the fine sand. The detection component in this application can detect the cleanliness of the sewage in the sewage storage bin, so as to adjust the speed of the backwashing water input by the water inlet pipe according to the detection result. While ensuring efficient flushing of the sand, the utilization rate of the backwashing water is also improved, and water resource waste is reduced.

[0011] Optionally, the flow equalizing component includes a fixed ring, a flow equalizing fan, a rotating ring plate, flow equalizing pieces, a fixed ring plate and a resetting member. The fixed ring penetrates through the water distribution plate and is arranged on the water distribution plate. The flow equalizing fan is rotatably arranged in the fixed ring. The rotating ring plate is rotatably arranged in the fixed ring and is connected to the side of the flow equalizing fan away from the sewage pipe. The fixed ring plate is arranged in the fixed ring and is located on the side of the rotating ring plate away from the flow equalizing fan. A plurality of groups of flow equalizing pieces are arranged. The plurality of groups of flow equalizing pieces are all movably arranged between the rotating ring plate and the fixed ring plate. A sliding block is arranged on the surface of the rotating ring plate close to the flow equalizing pieces. A sliding groove is opened on the flow equalizing piece corresponding to the sliding block. A moving block is arranged on the surface of the flow equalizing piece close to the fixed ring plate. A moving groove is opened 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 in a cross manner. The resetting member is arranged between the fixed ring and the rotating ring plate for resetting the flow equalizing fan.

[0012] By adopting the above technical solution, 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 rotation of the flow equalizing fan. The rotation of the flow equalizing fan drives the rotation of the rotating ring plate. Since sliding blocks are arranged on the surface of the rotating ring plate close to the flow equalizing pieces, sliding grooves are correspondingly formed on the flow equalizing pieces for the sliding blocks, moving blocks are arranged on the surface of the flow equalizing piece close to the fixed ring plate, and moving grooves are correspondingly formed on the fixed ring plate for the moving blocks. The projections of the moving grooves and the sliding grooves on the water distribution plate are arranged crosswise. Therefore, when the rotating ring plate rotates, the channel area surrounded by multiple groups of flow equalizing pieces 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 tank, avoiding the different usage degrees of sand and gravel at different positions in the sand and gravel tank due to the excessive concentrated input of the mixed water into the sand and gravel tank, and improving the usage effect and utilization rate of the sand and gravel.

[0013] Optionally, the detection component includes a laser emitter and a light intensity sensor. The laser emitter and the light intensity sensor are arranged at intervals and opposite to each other in the sewage tank. The light intensity sensor is used to receive the light output by the laser emitter. A flushing pump is arranged on the water inlet pipe. The flushing pump is electrically connected to the light intensity sensor. The higher the light intensity received by the light intensity sensor, the lower the rate of the flushing water input into the barrel through the water inlet pipe by the flushing pump. The lower the light intensity received by the light intensity sensor, the higher the rate of the flushing water input into the barrel through the water inlet pipe by the flushing pump.

[0014] By adopting the above technical solution, after the laser emitted by the laser emitter passes through the backwashing water in the sewage tank, since the backwashing water contains impurities, the light intensity may decrease. Therefore, the backwashing 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 the impurities in the backwashing water, and the lower the rate of the flushing water input into the barrel through the water inlet pipe by the flushing pump. The lower the light intensity received by the light intensity sensor, the higher the rate of the flushing water input into the barrel through the water inlet pipe by the flushing pump. 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.

[0015] Optionally, the opening and closing mechanism includes a first fixed cross plate, a second fixed cross plate, a first movable plate, a second movable plate, a first movable side plate, a second movable side plate, a fixed side plate, and a driving component. The first fixed cross plate is disposed above the medium sand bin and fixedly arranged on the second fixing plate. The first movable plate is disposed between the bottom plate of the medium sand bin and the first fixed cross plate and abuts against the lower surface of the first fixed cross plate. First filtering holes are formed in both the first fixed cross plate and the first movable plate. The second fixed cross plate is disposed above the fine sand bin and fixedly arranged on the second fixing plate. The second movable plate is disposed between the bottom plate of the fine sand bin and the second fixed cross plate and abuts against the lower surface of the second fixed cross plate. Second filtering holes are formed in both the second fixed cross plate and the second movable plate. There are two groups of the first movable side plates, and the two groups of the first movable side plates are respectively disposed on both sides of the first movable plate. There are two groups of the second movable side plates, and the two groups of the second movable side plates are respectively disposed on both sides of the second movable plate. There are two groups of the fixed side plates, and the two groups of the fixed side plates are respectively disposed on both sides of the bottom plates of the medium sand bin and the fine sand bin. The first movable side plate and the second movable side plate both abut against the side of the fixed side plate away from the inner wall of the barrel. Third filtering holes are formed in the first movable side plate and the fixed side plate, and fourth filtering holes are formed in the second movable side plate and the fixed side plate. A gap is provided between the fixed side plate and the inner wall of the barrel;

[0016] In the initial state, the first filtering holes on the first fixed cross plate and the first movable plate are staggered, the third filtering holes on the first movable side plate and the fixed side plate are aligned, the second filtering holes on the second fixed cross plate and the second movable plate are staggered, and the fourth filtering holes on the second movable side plate and the fixed side plate are aligned. After being filtered by the coarse sand bin, the sewage flows into the bottom of the barrel through the third filtering holes;

[0017] The driving component can independently drive the first movable plate to move towards the connecting pipe until the first filtering holes on the first fixed cross plate and the first movable plate are aligned, and the third filtering holes on the first movable side plate and the fixed side plate are staggered. The sewage is filtered in two layers through the coarse sand bin and the medium sand bin;

[0018] The driving component can also drive the first movable plate and the second movable plate to move towards the connecting pipe simultaneously until the first filter holes on the first fixed cross plate and the first movable plate are aligned, the second filter holes on the second fixed cross plate and the second movable plate are aligned, the third filter holes on the first movable side plate and the fixed side plate are staggered, the fourth filter holes on the second movable side plate and the fixed side plate are staggered, and the sewage is filtered in three layers through the coarse sand bin, the medium sand bin and the fine sand bin.

[0019] By adopting the above technical solution, when the sewage filtration effect needs to be relatively low, the driving component is not started, and only the device needs to be in the initial state. At this time, in the initial state, the first filter holes on the first fixed cross 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 cross plate and the second movable plate are staggered, 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 by the coarse sand bin and then flow into the bottom of the barrel through the third filter hole;

[0020] When further filtration of the sewage is required, the driving component is started. Under the action of the driving component, the first movable plate is driven alone to move towards the connecting pipe until the first filter holes on the first fixed cross plate and the first movable plate are aligned, and the third filter holes on the first movable side plate and the fixed side plate are staggered. At the same time, the second filter holes on the second fixed cross 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 is filtered in two layers through the coarse sand bin and the medium sand bin, it then flows into the bottom of the barrel through the fourth filter hole;

[0021] When deep filtration of the sewage is required, the driving component is continuously started, and the driving component drives the first movable plate and the second movable plate to move towards the connecting pipe simultaneously until the first filter holes on the first fixed cross plate and the first movable plate are aligned, the second filter holes on the second fixed cross plate and the second movable plate are aligned, the third filter holes on the first movable side plate and the fixed side plate are staggered, the fourth filter holes on the second movable side plate and the fixed side plate are staggered, and the sewage is filtered in three layers through the coarse sand bin, the medium sand bin and the fine sand bin and directly enters the bottom of the barrel, thereby realizing the opening and closing of the medium sand bin and the fine sand bin, and realizing the selection of different filtration effects according to actual usage requirements and improving the filtration efficiency.

[0022] Optionally, the driving assembly includes a driving motor, a rotating disk, a first driving rod, a second driving rod, and an elastic member. The driving motor is disposed on a surface of the second fixing plate away from the first fixing plate. The rotating disk is disposed on an output shaft of the driving motor. The first driving rod is disposed at an end of the first movable plate close to the driving motor and penetrates through the second fixing plate to abut against the rotating disk. The second driving rod is disposed at an end of the second movable plate close to the driving motor and penetrates through the second fixing plate to abut against the rotating disk. An arc-shaped driving groove is formed on a surface of the rotating disk away from the driving motor. Two ends of the arc-shaped driving groove are inclined surfaces. In an initial state, ends of the first driving rod and the second driving rod close to the second fixing plate are located in the arc-shaped driving groove. When the driving motor drives the rotating disk to rotate forward, the ends of the first driving rod and the second driving rod close to the second fixing plate are separated from the arc-shaped driving groove, and the first movable plate and the second movable plate move toward the first fixing plate. The elastic member is disposed on the first fixing plate and is configured to push the first movable plate and the second movable plate to move toward the second fixing plate when the driving motor drives the rotating disk to continue rotating forward, so that the ends of the first driving rod and the second driving rod close to the second fixing plate enter the arc-shaped driving groove.

[0023] By adopting the above technical solution, in the initial state, the driving motor is not started. At this time, the ends of the first driving rod and the second driving rod close to the second fixing plate are both located in the arc-shaped driving groove, and neither the first movable plate nor the second movable plate moves toward the connecting pipe. At this time, the sewage is only filtered through the coarse sand bin. When the driving motor is started forward, the driving motor drives the rotating disk to rotate forward until the first driving rod is separated from the arc-shaped driving groove. The first movable plate moves toward the connecting pipe, and the second driving rod is still located in the arc-shaped driving groove. At this time, the sewage is filtered through the coarse sand bin and the medium sand bin in two layers. When the driving motor is continuously started forward, the driving motor drives the rotating disk to continue rotating forward until both the first driving rod and the second driving rod are separated from the driving groove. The first movable plate and the second movable plate both move toward the connecting pipe. At this time, the sewage is filtered through the coarse sand bin, the medium sand bin, and the fine sand bin in three layers. When it is necessary to reset the first movable plate and the second movable plate, the driving motor is continuously started forward until the ends of the first driving rod and the second driving rod close to the second fixing plate move into the arc-shaped driving groove under the action of the elastic member.

[0024] Optionally, the vibration assembly includes a first vibration rod, a second vibration rod, a driving gear, a driven gear, a ratchet wheel, a pawl, a transmission wheel and a belt. The first vibration rod is arranged in the medium sand bin, and the second vibration rod is arranged in the fine sand bin. Both the first vibration rod and the second vibration rod are rotatably arranged on the second fixing plate. The first vibration rod and the second vibration rod are unevenly provided with bumps. The driving gear is arranged on the output shaft of the driving motor, and the driven gear is arranged on the side of the second fixing plate away from the first fixing plate, and the driving gear and the driven gear are meshed with each other. An installation groove is formed on the side of the rotating disk away from the first fixing plate. The pawl is arranged on the output shaft of the driving motor and is located in the installation groove. The ratchet wheel is arranged on the inner wall of the installation groove. When the output shaft of the driving motor rotates forward, the ratchet wheel and the pawl are meshed with each other. A plurality of groups of the first vibration rods and the second vibration rods are provided. One group of the plurality of groups of second vibration rods penetrates through the second fixing plate and is connected to the driven gear. A plurality of groups of the transmission wheels are provided, and the plurality of groups of transmission wheels are respectively arranged on the ends of the plurality of groups of the first vibration rods and the plurality of groups of the second vibration rods away from the first fixing plate. The transmission wheels are connected and driven by the belt.

[0025] By adopting the above technical solution, when the driving motor is started forward, when the output shaft of the driving motor rotates forward, the ratchet wheel and the pawl are meshed with each other to drive the rotation of the rotating disk. After completing the opening and closing work of the medium sand bin and the fine sand bin according to the actual filtering requirements, the driving motor is started in reverse. When the output shaft of the driving motor rotates in reverse, the ratchet wheel and the pawl are not meshed, and the rotating disk remains stationary. However, since the driving gear and the driven gear are meshed with each other, and one group of the plurality of groups of second vibration rods penetrates through the second fixing plate and is connected to the driven gear, the transmission wheels are respectively arranged on the ends of the plurality of groups of the first vibration rods and the plurality of groups of the second vibration rods, and the transmission wheels are connected and driven by the belt. Therefore, the rotation of the driven gear can drive the self-rotation of the first vibration rod and the second vibration rod. Also, since the first vibration rod and the second vibration rod are unevenly provided with bumps, the first vibration rod and the second vibration rod will generate vibrations during self-rotation, so as to vibrate the medium sand and the fine sand, thereby reducing the impurities attached to the medium sand and the fine sand and further improving the flushing effect on the medium sand and the fine sand.

[0026] Optionally, an air inlet pipe is arranged on the water inlet pipe, and an air pump is arranged at one end of the air inlet pipe away from the water inlet pipe.

[0027] By adopting the above technical solution, the air pump inputs gas into the bottom of the barrel through the air inlet pipe. Under the dual action of the gas and the backwashing water, the flushing effect and the flushing efficiency of the sand and gravel in the barrel can be further improved, and the amount of flushing water consumed during backwashing can be further reduced.

[0028] Optionally, a flow equalizing pipe is arranged at the inner bottom of the barrel body. One end of the flow equalizing pipe is connected to the end of the connecting pipe away from the three-way valve, and the other end abuts against the water outlet pipe. The flow equalizing pipe is provided with water passing holes at intervals. A plurality of groups of stabilizing rings are sleeved on the flow equalizing pipe. The stabilizing rings are fixedly arranged on the inner wall of the barrel body, and a plurality of groups of the stabilizing rings are connected to each other.

[0029] By adopting the above technical solution, the flow equalizing pipe can evenly distribute the backwashing water and gas input to the bottom of the barrel body, and output the backwashing water and gas from a plurality of groups of water passing holes, thereby improving the overall backwashing effect on the sand and gravel. The plurality of groups of stabilizing rings can further improve the stability of the flow equalizing pipe, avoid damage or dislocation of the flow equalizing pipe caused by long-term use of the flow equalizing pipe, and the connection between the stabilizing rings can further improve the stability of the stabilizing rings and the flow equalizing pipe.

[0030] Optionally, an end cover is arranged on the surface of the second fixing plate away from the first fixing plate, and the second fixing plate is inserted into the barrel body. The end cover and the barrel body are provided with a lock for improving the connection strength between the end cover and the barrel body. A sliding groove is formed on the mounting seat, and a sliding strip corresponding to the sliding groove is arranged on the end cover. The length of the sliding strip is greater than the length of the barrel body.

[0031] By adopting the above technical solution, the second fixing plate and the barrel body are connected in an inserting manner, so that the disassembly of the second fixing plate can be realized. The sliding strip on the end cover and the sliding groove on the mounting seat can facilitate the movement of the disassembled second fixing plate. Move the second fixing plate until the coarse sand bin, medium sand bin and fine sand bin are removed from the barrel body, so as to facilitate the replacement of the sand and gravel and the maintenance of the equipment. The lock can improve the connection strength between the end cover and the barrel body when the second fixing plate is inserted and installed in the barrel body.

[0032] In summary, the present application includes at least one of the following beneficial technical effects:

[0033] 1. When the sewage filtration effect needs to be relatively 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 filtration holes on the first fixed cross plate and the first movable plate are staggered, the third filtration holes on the first movable side plate and the fixed side plate are aligned, the second filtration holes on the second fixed cross plate and the second movable plate are staggered, and the fourth filtration 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 through the third filtration hole; when further filtration of the sewage is required, the driving component is started. Under the action of the driving component, the first movable plate is driven alone to move towards the connecting pipe until the first filtration holes on the first fixed cross plate and the first movable plate are aligned, and the third filtration holes on the first movable side plate and the fixed side plate are staggered. At the same time, the second filtration holes on the second fixed cross plate and the second movable plate are staggered, and the fourth filtration holes on the second movable side plate and the fixed side plate are aligned. After the sewage is filtered through the coarse sand bin and the medium sand bin in two layers, it then flows into the bottom of the barrel through the fourth filtration hole; when deep filtration of the sewage is required, the driving component is continuously started, and the driving component drives both the first movable plate and the second movable plate to move towards the connecting pipe until the first filtration holes on the first fixed cross plate and the first movable plate are aligned, the second filtration holes on the second fixed cross plate and the second movable plate are aligned, the third filtration holes on the first movable side plate and the fixed side plate are staggered, and the fourth filtration holes on the second movable side plate and the fixed side plate are staggered. The sewage is directly filtered through the coarse sand bin, the medium sand bin and the fine sand bin in three layers and enters the bottom of the barrel, thereby realizing the opening and closing of the medium sand bin and the fine sand bin, and realizing the selection of different filtration effects according to actual usage requirements and improving the filtration efficiency;

[0034] 2. After the laser emitted by the laser emitter passes through the backwash water in the sewage bin, since the backwash water contains impurities, the light intensity may decrease. Therefore, the backwashing 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, and the lower the rate of the backwash water input into the barrel through the water inlet pipe by the flush pump. The lower the light intensity received by the light intensity sensor, the higher the rate of the backwash water input into the barrel through the water inlet pipe by the flush pump. While ensuring efficient flushing of the sand and gravel, the utilization rate of the backwash water is also improved, and water resource waste is reduced;

[0035] 3. The sewage pipe inputs the mixed water of sewage and flushing water into the sewage storage tank. When the mixed water passes through the flow equalizing fan, it will drive the rotation of the flow equalizing fan. The rotating flow equalizing fan drives the rotating ring plate to rotate. Since sliding blocks are arranged on the side of the rotating ring plate close to the flow equalizing pieces, sliding grooves are correspondingly opened on the flow equalizing pieces for the sliding blocks, moving blocks are arranged on the side of the flow equalizing pieces close to the fixed ring plate, and moving grooves are correspondingly opened on the fixed ring plate for the moving blocks. The projections of the moving grooves and the sliding grooves on the water distribution plate are arranged crosswise. Therefore, when the rotating ring plate rotates, the channel area surrounded by multiple groups of flow equalizing pieces can be changed. The greater the flow velocity of the mixed water, the smaller the channel area. By installing multiple groups of flow equalizing components, the sewage in the sewage storage tank can be evenly transported into the sand and gravel storage tank, avoiding the uneven use degree of sand and gravel at different positions in the sand and gravel storage tank due to the excessive concentrated input of the mixed water into the sand and gravel storage tank, and improving the use effect and utilization rate of the sand and gravel;

[0036] 4. When the driving motor is started forward, when the output shaft of the driving motor rotates forward, the ratchet and the pawl are engaged with each other to drive the rotation of the rotating disk. After completing the opening and closing work of the medium sand storage tank and the fine sand storage tank according to the actual filtration requirements, the driving motor is started in reverse. When the output shaft of the driving motor rotates in reverse, the ratchet and the pawl are not engaged, and the rotating disk remains stationary. However, since the driving gear and the driven gear are engaged with each other, and one of the multiple groups of second vibrating rods passes through the second fixing plate and is connected to the driven gear, the transmission wheels are respectively arranged at the ends of the multiple groups of first vibrating rods and the multiple groups of second vibrating rods, and the transmission wheels are connected and driven by a belt. Therefore, the rotation of the driven gear can drive the self-rotation of the first vibrating rods and the second vibrating rods. Also, since the bumps are unevenly arranged on the first vibrating rods and the second vibrating rods, the first vibrating rods and the second vibrating rods will generate vibrations during self-rotation, thereby realizing the vibration of the medium sand and the fine sand, reducing the impurities attached to the medium sand and the fine sand, further improving the flushing effect of the medium sand and the fine sand. The air pump inputs gas into the bottom of the barrel through the air inlet pipe. Under the dual action of the gas and the backwashing water, the flushing effect and efficiency of the sand and gravel in the barrel can be further improved, and the amount of flushing water consumed during backwashing can be further reduced.

[0047] The following further elaborates on this application in conjunction with the Figure 1-8 accompanying drawings.

[0048] The embodiment of the present application discloses an agricultural irrigation horizontal net type sand and gravel filtration treatment system. Refer to Figure 1 and Figure 2 , an agricultural irrigation horizontal net type sand and gravel filtration treatment system, including a mounting base 1 and a barrel body 2. The barrel body 2 is arranged on the mounting base 1. A sewage pipe 21 is arranged on the barrel body 2. A sewage pump 221 is arranged on the sewage pipe 21. A three-way valve 22 is arranged on the sewage pipe 21. The sewage pipe 21 is connected to one valve port of the three-way valve 22. An inlet pipe 23 and a connecting pipe 24 are respectively arranged on the other two valve ports of the three-way valve 22. One end of the connecting pipe 24 far from the three-way valve 22 is connected to the barrel body 2. A water distribution plate 25 is arranged in the barrel body 2. The water distribution plate 25 is arranged below the connection part of the sewage pipe 21 and the barrel body 2. The water distribution plate 25 divides the space in the barrel body 2 into a sewage bin 26 and a sand and gravel bin 27. A plurality of flow equalizing components 3 for uniformly conveying the sewage in the sewage bin 26 into the sand and gravel bin 27 are arranged on the water distribution plate 25;

[0049] A coarse sand bin 271, a medium sand bin 272 and a fine sand bin 273 are arranged in the sand and gravel bin 27. Coarse sand is placed in the coarse sand bin 271, medium sand is placed in the medium sand bin 272, and fine sand is placed in the fine sand bin 273. Filter holes with different diameters are opened on the bottom plates of the coarse sand bin 271, the medium sand bin 272 and the fine sand bin 273. The coarse sand bin 271 is arranged below the water distribution plate 25, the fine sand bin 273 is arranged below the coarse sand bin 271, and the medium sand bin 272 is arranged between the coarse sand bin 271 and the fine sand bin 273. An outlet pipe 28 for outputting the filtered sewage is arranged on the barrel body 2. An opening and closing valve 29 is arranged on the outlet pipe 28. A vibration component 4 for vibrating the medium sand and 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 and automatically adjusting the input speed of the backwashing water of the inlet pipe 23 is arranged in the sewage bin 26;

[0050] A first fixing plate 6 and a second fixing plate 7 are respectively arranged at both ends inside 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 fixing plate 6 and the second fixing plate 7. And the first fixing plate 6 is arranged close to the connecting pipe 24, and the second fixing plate 7 is arranged close to the outlet pipe 28. The connecting pipe 24 is communicated with one side of the first fixing plate 6 close to the second fixing plate 7, and the outlet pipe 28 is communicated with one side of the second fixing plate 7 close to the first fixing plate 6. An opening and closing mechanism 8 for respectively opening and closing the medium sand bin 272 and the fine sand bin 273 to achieve different filtration effects on sewage is arranged on the first fixing plate 6 and the second fixing plate 7.

[0051] 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 storage chamber 26 in the barrel 2 through the sewage pipe 21. Under the action of the flow equalizing component 3 on the water distribution plate 25, the sewage is evenly transported into the sand storage chamber 27 for filtration. The opening and closing mechanism 8 in this application can open and close the medium sand storage chamber 272 and the fine sand storage chamber 273. When both the medium sand storage chamber 272 and the fine sand storage chamber 273 are closed, the sewage is filtered through the coarse sand storage chamber 271. When only the fine sand storage chamber 273 is closed, the sewage is filtered through the coarse sand storage chamber 271 and the medium sand storage chamber 272 in two layers. When both the medium sand storage chamber 272 and the fine sand storage chamber 273 are open, the sewage is filtered through the coarse sand storage chamber 271, the medium sand storage chamber 272, and the fine sand storage chamber 273 in three layers. In this way, different filtration effects can be selected according to actual usage requirements and the filtration efficiency can be improved. When it is necessary to backwash the sand in the barrel 2, open both the medium sand storage chamber 272 and the fine sand storage chamber 273 through the opening and closing mechanism 8. Then, by adjusting the three-way valve 22, connect the water inlet pipe 23 and the connecting pipe 24. Open the flushing pump 53 in the forward direction and open the sewage pump 221 in the reverse direction. The flushing water enters the barrel 2 through the connecting pipe 24. As the amount of flushing water in the barrel 2 increases, the flushing water can backwash the impurities filtered by the sand in the coarse sand storage chamber 271, the medium sand storage chamber 272, and the fine sand storage chamber 273. The flushing water carries the impurities and is output from the sewage pipe 21, thus ensuring the filtration effect of the device on sewage. During backwashing, the vibration component 4 in this 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 backwashing effect on the medium sand and fine sand. The detection component 5 in this application can detect the cleanliness of the sewage in the sewage storage chamber 26, and thus adjust the speed of the backwashing water input from the water inlet pipe 23 according to the detection result. While ensuring efficient flushing of the sand, it also improves the utilization rate of the backwashing water and reduces water resource waste.

[0052] Refer to Figure 2 and Figure 3, the flow equalizing assembly 3 includes a fixing ring 31, a flow equalizing fan 32, a rotating ring plate 33, flow equalizing plates 34, a fixing ring plate 35 and a resetting member 36. The fixing ring 31 penetrates through the water distribution plate 25 and is arranged on the water distribution plate 25. The flow equalizing fan 32 is rotatably arranged in the fixing ring 31. The rotating ring plate 33 is rotatably arranged in the fixing ring 31 and is connected to the side of the flow equalizing fan 32 away from the sewage pipe 21. The fixing ring plate 35 is arranged in the fixing ring 31 and is located on the side of the rotating ring plate 33 away from the flow equalizing fan 32. A plurality of groups of flow equalizing plates 34 are provided. The plurality of groups of flow equalizing plates 34 are all movably arranged between the rotating ring plate 33 and the fixing ring plate 35. A sliding block 331 is arranged on the surface of the rotating ring plate 33 close to the flow equalizing plates 34. A sliding groove 341 is correspondingly formed on the flow equalizing plate 34 for the sliding block 331. A moving block 342 is arranged on the surface of the flow equalizing plate 34 close to the fixing ring plate 35. A moving groove 351 is correspondingly formed on the fixing ring plate 35 for the moving block 342. The projections of the moving groove 351 and the sliding groove 341 on the water distribution plate 25 are arranged in a crosswise manner. The resetting member 36 is arranged between the fixing ring 31 and the rotating ring plate 33 for resetting the flow equalizing fan 32. In this embodiment, the resetting member 36 is a torsion spring.

[0053] The sewage pipe 21 inputs the mixed water of sewage and flushing water into the sewage chamber 26. When the mixed water passes through the flow equalizing fan 32, it will drive the rotation of the flow equalizing fan 32. The rotation of the flow equalizing fan 32 drives the rotation of the rotating ring plate 33. Since a sliding block 331 is arranged on the surface of the rotating ring plate 33 close to the flow equalizing plates 34, a sliding groove 341 is correspondingly formed on the flow equalizing plate 34 for the sliding block 331. A moving block 342 is arranged on the surface of the flow equalizing plate 34 close to the fixing ring plate 35. A moving groove 351 is correspondingly formed on the fixing ring plate 35 for the moving block 342. The projections of the moving groove 351 and the sliding groove 341 on the water distribution plate 25 are arranged in a crosswise manner. Therefore, when the rotating ring plate 33 rotates, it can change the channel area surrounded by the plurality of groups of flow equalizing plates 34. The greater the flow rate of the mixed water, the smaller the channel area. By installing a plurality of groups of flow equalizing assemblies 3, the sewage in the sewage chamber 26 can be evenly transported into the gravel chamber 27, avoiding the uneven use degree of the gravel at different positions in the gravel chamber 27 due to the excessive concentration of the mixed water input into the gravel chamber 27, and improving the use effect and utilization rate of the gravel.

[0054] Refer to Figure 2 , the detection assembly 5 includes a laser emitter 51 and a light intensity sensor 52. The laser emitter 51 and the light intensity sensor 52 are arranged at intervals and oppositely in the sewage chamber 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 rate of the flushing water input into the barrel body 2 through the water inlet pipe 23 by the flushing pump 53. The lower the light intensity received by the light intensity sensor 52, the higher the rate of the flushing water input into the barrel body 2 through the water inlet pipe 23 by the flushing pump 53.

[0055] After the laser emitted by the laser emitter 51 passes through the backwash water in the sewage sump 26, since there are impurities in the backwash water, the light intensity may decrease. Therefore, the backwashing 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 the washing water input into the barrel body 2 through the water inlet pipe 23 by the washing pump 53. The lower the light intensity received by the light intensity sensor 52, the higher the rate of the washing water input into the barrel body 2 through the water inlet pipe 23 by the washing pump 53. While ensuring efficient washing of the sand and gravel, the utilization rate of the backwash water is also improved, and water resource waste is reduced.

[0056] Referring to Figure 4 and Figure 5 As shown in FIG. 8, the opening and closing mechanism 8 includes a first fixed cross plate 81, a second fixed cross plate 82, a first movable plate 83, a second movable plate 84, a first movable side plate 85, a second movable side plate 86, a fixed side plate 87 and a driving assembly 88. The first fixed cross plate 81 is disposed above the medium sand bin 272 and fixedly disposed on the second fixing plate 7. The first movable plate 83 is disposed between the bottom plate of the medium sand bin 272 and the first fixed cross plate 81 and abuts against the lower surface of the first fixed cross plate 81. First filtering holes are formed on both the first fixed cross plate 81 and the first movable plate 83. The second fixed cross plate 82 is disposed above the fine sand bin 273 and fixedly disposed on the second fixing plate 7. The second movable plate 84 is disposed between the bottom plate of the fine sand bin 273 and the second fixed cross plate 82 and abuts against the lower surface of the second fixed cross plate 82. Second filtering holes are formed on both the second fixed cross plate 82 and the second movable plate 84. Two groups of the first movable side plates 85 are provided, and the two groups of the first movable side plates 85 are respectively disposed on both sides of the first movable plate 83. Two groups of the second movable side plates 86 are provided, and the two groups of the second movable side plates 86 are respectively disposed on both sides of the second movable plate 84. Two groups of the fixed side plates 87 are provided, and the two groups of the fixed side plates 87 are respectively disposed on both sides of the bottom plates of the medium sand bin 272 and the fine sand bin 273. The first movable side plate 85 and the second movable side plate 86 both abut against one side of the fixed side plate 87 away from the inner wall of the barrel body 2. Third filtering holes are formed on the first movable side plate 85 and the fixed side plate 87, and fourth filtering holes are formed on the second movable side plate 86 and the fixed side plate 87. A gap is provided between the fixed side plate 87 and the inner wall of the barrel body 2.

[0057] In the initial state, the first filtering holes on the first fixed cross plate 81 and the first movable plate 83 are staggered, the third filtering holes on the first movable side plate 85 and the fixed side plate 87 are aligned, the second filtering holes on the second fixed cross plate 82 and the second movable plate 84 are staggered, and the fourth filtering holes on the second movable side plate 86 and the fixed side plate 87 are aligned. After being filtered by the coarse sand bin 271, the sewage flows into the bottom of the barrel body 2 through the third filtering holes.

[0058] The driving component 88 can drive the first movable plate 83 to move towards the connecting pipe 24 alone until the first filter holes on the first fixed cross plate 81 and the first movable plate 83 are aligned, and the third filter holes on the first movable side plate 85 and the fixed side plate 87 are staggered. The sewage is filtered through the coarse sand bin 271 and the medium sand bin 272 in two layers.

[0059] The driving component 88 can also drive the first movable plate 83 and the second movable plate 84 to move towards the connecting pipe 24 simultaneously until the first filter holes on the first fixed cross plate 81 and the first movable plate 83 are aligned, the second filter holes on the second fixed cross plate 82 and the second movable plate 84 are aligned, the third filter holes on the first movable side plate 85 and the fixed side plate 87 are staggered, and the fourth filter holes on the second movable side plate 86 and the fixed side plate 87 are staggered. The sewage is filtered through the coarse sand bin 271, the medium sand bin 272 and the fine sand bin 273 in three layers.

[0060] When the sewage filtration effect needs to be relatively low, the driving component 88 is not started, and only the device needs to be in the initial state. At this time, in the initial state, the first filter holes on the first fixed cross plate 81 and the first movable plate 83 are staggered, the third filter holes on the first movable side plate 85 and the fixed side plate 87 are aligned, the second filter holes on the second fixed cross plate 82 and the second movable plate 84 are staggered, and the fourth filter holes on the second movable side plate 86 and the fixed side plate 87 are aligned. After the sewage enters the sand and gravel bin 27, it can be filtered through the coarse sand bin 271 and then flow into the bottom of the barrel 2 from the third filter hole;

[0061] When further filtration of the sewage is required, the driving component 88 is started. Under the action of the driving component 88, the first movable plate 83 is driven alone to move towards the connecting pipe 24 until the first filter holes on the first fixed cross plate 81 and the first movable plate 83 are aligned, and the third filter holes on the first movable side plate 85 and the fixed side plate 87 are staggered. At the same time, the second filter holes on the second fixed cross plate 82 and the second movable plate 84 are staggered, and the fourth filter holes on the second movable side plate 86 and the fixed side plate 87 are aligned. The sewage is filtered through the coarse sand bin 271 and the medium sand bin 272 in two layers and then flows into the bottom of the barrel 2 from the fourth filter hole;

[0062] When deep filtration of sewage is required, the drive assembly 88 is started continuously. The drive assembly 88 drives the first movable plate 83 and the second movable plate 84 to move towards the connecting pipe 24 simultaneously until the first filter holes on the first fixed cross plate 81 and the first movable plate 83 are aligned, the second filter holes on the second fixed cross plate 82 and the second movable plate 84 are aligned, the third filter holes on the first movable side plate 85 and the fixed side plate 87 are staggered, and the fourth filter holes on the second movable side plate 86 and the fixed side plate 87 are staggered. The sewage passes through the coarse sand bin 271, the medium sand bin 272, and the fine sand bin 273 for three-layer filtration and directly enters the bottom of the barrel body 2, thereby realizing the opening and closing of the medium sand bin 272 and the fine sand bin 273, and realizing the selection of different filtration effects according to actual usage requirements and improving the filtration efficiency.

[0063] Refer to Figure 5 , Figure 6 Figure 7 , the drive assembly 88 includes a drive motor 881, a rotating disk 882, a first drive rod 883, a second drive rod 884, and an elastic member 885. The drive motor 881 is disposed on the surface of the second fixed plate 7 away from the first fixed plate 6. The rotating disk 882 is disposed on the output shaft of the drive motor 881. The first drive rod 883 is disposed at one end of the first movable plate 83 close to the drive motor 881 and penetrates through the second fixed plate 7 to abut against the rotating disk 882. The second drive rod 884 is disposed at one end of the second movable plate 84 close to the drive motor 881 and penetrates through the second fixed plate 7 to abut against the rotating disk 882. An arc-shaped drive groove 886 is disposed on the surface of the rotating disk 882 away from the drive motor 881. The two ends of the arc-shaped drive groove 886 are inclined surfaces. In the initial state, the ends of the first drive rod 883 and the second drive rod 884 close to the second fixed plate 7 are located in the arc-shaped drive groove 886. When the drive motor 881 drives the rotating disk 882 to rotate forward, the ends of the first drive rod 883 and the second drive rod 884 close to the second fixed plate 7 are separated from the arc-shaped drive groove 886, and the first movable plate 83 and the second movable plate 84 move towards the first fixed plate 6. The elastic member 885 is disposed on the first fixed plate 6 and is used to push the first movable plate 83 and the second movable plate 84 to move towards the second fixed plate 7 when the drive motor 881 drives the rotating disk 882 to continue rotating forward, so that the ends of the first drive rod 883 and the second drive rod 884 close to the second fixed plate 7 enter the arc-shaped drive groove 886. In this embodiment, the elastic member 885 is a spring, and the spring is a preferred manner in this embodiment. In other embodiments, the elastic member 885 can be an elastic block, etc.

[0064] In the initial state, the driving motor 881 is not started. At this time, one ends of the first driving rod 883 and the second driving rod 884 close to the second fixing plate 7 are both located in the arc-shaped driving groove 886. The first movable plate 83 and the second movable plate 84 do not move towards the connecting pipe 24. At this time, the sewage is only filtered through the coarse sand bin 271. When the driving motor 881 is started forward, the driving motor 881 drives the rotating disk 882 to rotate forward until the first driving rod 883 is separated from the arc-shaped driving groove 886. The first movable plate 83 moves towards the connecting pipe 24, and the second driving rod 884 is still located in the arc-shaped driving groove 886. At this time, the sewage is filtered through the coarse sand bin 271 and the medium sand bin 272 in two layers. When the driving motor 881 is continuously started forward, the driving motor 881 drives the rotating disk 882 to continue to rotate forward until both the first driving rod 883 and the second driving rod 884 are separated from the driving groove. The first movable plate 83 and the second movable plate 84 both move towards the connecting pipe 24. At this time, the sewage is filtered through the coarse sand bin 271, the medium sand bin 272 and the fine sand bin 273 in three layers. When it is necessary to reset the first movable plate 83 and the second movable plate 84, the driving motor 881 is continuously started forward until one ends of the first driving rod 883 and the second driving rod 884 close to the second fixing plate 7 move into the arc-shaped driving groove 886 under the action of the elastic member 885.

[0065] Referring to Figure 6 , Figure 7 and Figure 8 , the vibration assembly 4 includes a first vibration rod 41, a second vibration rod 42, a driving gear 43, a driven gear 44, a ratchet wheel 45, a pawl 46, a transmission wheel 47 and a belt 48. The first vibration rod 41 is arranged in the medium sand bin 272, and the second vibration rod 42 is arranged in the fine sand bin 273. Both the first vibration rod 41 and the second vibration rod 42 are rotatably arranged on the second fixing plate 7. The first vibration rod 41 and the second vibration rod 42 are unevenly provided with bumps. The driving gear 43 is arranged on the output shaft of the driving motor 881. The driven gear 44 is arranged on the side of the second fixing plate 7 away from the first fixing plate 6, and the driving gear 43 and the driven gear 44 are meshed with each other. An installation groove is formed on the side of the rotating disk 882 away from the first fixing plate 6. The pawl 46 is arranged on the output shaft of the driving motor 881 and is located in the installation groove. The ratchet wheel 45 is arranged on the inner wall of the installation groove. When the output shaft of the driving motor 881 rotates forward, the ratchet wheel 45 and the pawl 46 are meshed with each other. There are multiple groups of the first vibration rod 41 and the second vibration rod 42. One group of the multiple groups of the second vibration rods 42 penetrates through the second fixing plate 7 and is connected to the driven gear 44. There are multiple groups of the transmission wheels 47. The multiple groups of the transmission wheels 47 are respectively arranged on the ends of the multiple groups of the first vibration rods 41 and the multiple groups of the second vibration rods 42 away from the first fixing plate 6. The transmission wheels 47 are connected and driven by the belt 48.

[0066] Forwardly start the drive motor 881. When the output shaft of the drive motor 881 rotates forward, the ratchet wheel 45 and the ratchet pawl 46 engage with each other to drive the rotation of the rotating disk 882. After completing the opening and closing work of the medium sand bin 272 and the fine sand bin 273 according to the actual filtration requirements, reverse-start the drive motor 881. When the output shaft of the drive motor 881 rotates in the reverse direction, the ratchet wheel 45 and the ratchet pawl 46 do not engage, and the rotating disk 882 remains stationary. However, since the driving gear 43 and the driven gear 44 engage with each other, and one of a plurality of second vibrating rods 42 penetrates through the second fixing plate 7 and is connected to the driven gear 44, the transmission wheels 47 are respectively arranged at the ends of a plurality of first vibrating rods 41 and a plurality of second vibrating rods 42, and the transmission wheels 47 are connected and driven by a belt 48. Therefore, the rotation of the driven gear 44 can drive the self-rotation of the first vibrating rod 41 and the second vibrating rod 42. Also, since the bumps are unevenly arranged on the first vibrating rod 41 and the second vibrating rod 42, the first vibrating rod 41 and the second vibrating rod 42 will generate vibrations during self-rotation, thereby realizing the vibration of the medium sand and the fine sand, reducing the impurities attached to the medium sand and the fine sand, and further improving the flushing effect on the medium sand and the fine sand.

[0067] Refer to Figure 1 and Figure 2 , an air inlet pipe 231 is arranged on the water inlet pipe 23, and an air pump 232 is arranged at one end of the air inlet pipe 231 away from the water inlet pipe 23. The air pump 232 inputs gas to the bottom of the barrel body 2 through the air inlet pipe 231. Under the dual action of the gas and the backwashing water, the flushing effect and the flushing efficiency of the sand and gravel in the barrel body 2 can be further improved, and the amount of flushing water consumed during backwashing can be further reduced.

[0068] A flow equalizing pipe 9 is arranged at the inner bottom of the barrel body 2. One end of the flow equalizing pipe 9 is connected to one end of the connecting pipe 24 away from the three-way valve 22, and the other end abuts against the water outlet pipe 28. Water passing holes are spaced apart on the flow equalizing pipe 9. A plurality of stabilizing rings 91 are sleeved on the flow equalizing pipe 9, and the stabilizing rings 91 are fixedly arranged on the inner wall of the barrel body 2, and a plurality of stabilizing rings 91 are connected to each other. The flow equalizing pipe 9 can evenly distribute the backwashing water and the gas input to the bottom of the barrel body 2, and output the backwashing water and the gas from a plurality of water passing holes, thereby improving the overall backwashing effect on the sand and gravel. The plurality of stabilizing rings 91 can further improve the stability of the flow equalizing pipe 9, avoid damage or dislocation of the flow equalizing pipe 9 caused by long-term use of the flow equalizing pipe 9, and the connection between the stabilizing rings 91 can further improve the stability of the stabilizing rings 91 and the flow equalizing pipe 9.

[0069] Refer to Figure 1, an end cap 10 is provided on the side of the second fixing plate 7 away from the first fixing plate 6, and the second fixing plate 7 is inserted into the barrel body 2. The end cap 10 and the barrel body 2 are provided with a locking buckle 101 for improving the connection strength between the end cap 10 and the barrel body 2. A sliding groove 103 is formed on the mounting seat 1, and a sliding bar 102 corresponding to the sliding groove 103 is provided on the end cap 10. The length of the sliding bar 102 is set to be greater than the length of the barrel body 2. The second fixing plate 7 and the barrel body 2 are connected by insertion, which can realize the disassembly of the second fixing plate 7. The sliding bar 102 on the end cap 10 and the sliding groove 103 on the mounting seat 1 can facilitate the movement of the disassembled second fixing plate 7. Move the second fixing plate 7 until the coarse sand bin 271, the medium sand bin 272 and the fine sand bin 273 are removed from the barrel body 2, so as to facilitate the replacement of the sand and gravel and the maintenance of the equipment. The locking buckle 101 can improve the connection strength between the end cap 10 and the barrel body 2 when the second fixing plate 7 is inserted and installed in the barrel body 2.

[0070] The implementation principle of an agricultural irrigation horizontal net-type sand and gravel filtration treatment system according to an embodiment of the present application is as follows:

[0071] 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 storage bin 26 in the barrel body 2 through the sewage pipe 21. Under the action of the flow equalizing component 3 on the water distribution plate 25, the sewage is evenly transported into the sand storage bin 27 for filtration. The opening and closing mechanism 8 in this application can open and close the medium sand bin 272 and the fine sand bin 273. When both the medium sand bin 272 and the fine sand bin 273 are closed, the sewage is filtered through the coarse sand bin 271 for the first layer. When only the fine sand bin 273 is closed, the sewage is filtered through the coarse sand bin 271 and the medium sand bin 272 for the second layer. When both the medium sand bin 272 and the fine sand bin 273 are open, the sewage is filtered through the coarse sand bin 271, the medium sand bin 272, and the fine sand bin 273 for the third layer. In this way, different filtration effects can be selected according to actual usage requirements and the filtration efficiency can be improved. When it is necessary to backwash the sand in the barrel body 2, open both the medium sand bin 272 and the fine sand bin 273 through the opening and closing mechanism 8, and then adjust the three-way valve 22 to connect the water inlet pipe 23 and the connecting pipe 24. Open the flushing pump 53 in the forward direction and open the sewage pump 221 in the reverse direction. 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 in the coarse sand bin 271, the medium sand bin 272, and the fine sand bin 273. The flushing water carries the impurities and is output from the sewage pipe 21, thereby ensuring the filtration effect of the device on sewage. During backwashing, the vibration component 4 in this 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 on the medium sand and fine sand. The detection component 5 in this application can detect the cleanliness of the sewage in the sewage storage bin 26, thereby adjusting the speed of the backwashing water input from the water inlet pipe 23 according to the detection result. While ensuring efficient flushing of the sand, it also improves the utilization rate of the backwashing water and reduces water resource waste.
