Rotary silt separating irrigation device

Abstract

This invention discloses a rotary sediment separation irrigation device, which relates to the field of water conservancy engineering production technology. The device includes a tank, a filter tank, a servo motor, a baffle, and a slag discharge pipe. When the water level drops to the first mark, it indicates that multiple filter screens are clogged. When the water level rises to the second mark, it indicates that excessive gravel and sediment have accumulated in the slag discharge pipe. Pulling out the pin causes the baffle and slag discharge pipe to descend synchronously, changing the water flow path. The water backwashes the multiple filter screens, and the slag discharge pipe discharges slag, thus automatically cleaning the multiple filter screens. Furthermore, workers can accurately determine whether slag discharge is necessary by observing changes in the water level.

Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering production technology, and in particular to a rotary sediment separation irrigation device. Background Technology

[0002] The essence of a sediment separation irrigation device is to use centrifugal force to achieve solid-liquid separation, ensuring the stable operation of the irrigation system and protecting crop growth. Its specific functions are: 1. Protecting irrigation equipment, preventing sediment from clogging drip irrigation tapes, nozzles, pipes, and other equipment, reducing equipment wear and malfunctions, extending service life, and reducing maintenance costs; 2. Improving irrigation quality, preventing sediment from accumulating on the surface of farmland soil, preventing soil compaction, ensuring soil aeration and water permeability, and creating a good environment for crop root growth.

[0003] To improve water filtration, sediment separation irrigation devices are usually equipped with filter screens to filter out fine sediment. However, long-term filtration can cause a large amount of sediment to adhere to the surface of the filter screen, resulting in poor water flow or even blockage. This not only requires frequent cleaning or replacement of the filter screen to maintain device operation, but also reduces the lifespan of the filter screen, thereby increasing operating costs.

[0004] After operating for a period of time, the device will accumulate a large amount of mud, sand and gravel inside, requiring regular slag removal and cleaning. This usually requires staff to operate, but it is difficult for staff to accurately judge when to remove the slag, which brings inconvenience to daily maintenance.

[0005] To address these issues, we designed a rotary sediment separation irrigation device. Summary of the Invention

[0006] In order to overcome the defects of the prior art, the present invention provides a rotary sediment separation irrigation device. The device allows the operator to observe the water level changes, i.e., whether the water level is rising or falling, and then operate accordingly. This allows for precise judgment and cleaning of the filter screen and slag removal. The backwashing and slag removal process does not affect the irrigation of crops.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] A rotary sediment separation irrigation device includes: a tank, a filter tank, a servo motor, a baffle, and a slag discharge pipe;

[0009] The tank body is equipped with a first partition plate with a through opening. The tank body has an observation port for observing water level changes. A rectangular sleeve is provided on the bottom surface of the tank body. The filter tank includes a diversion tank, a rotating tank, and a limiting groove. The diversion tank is divided into two chambers by a second partition plate. Both chambers have multiple openings on their walls and are connected. A pipe is provided on the bottom surface of the diversion tank. The diversion tank and the rotating tank are rotatably connected and interconnected. The limiting groove is L-shaped and located below the rotating tank. The top surface of the horizontal section of the limiting groove is inclined.

[0010] One end of the inlet pipe goes down through the diversion tank and extends into the interior of the rotating tank, while the other end goes through the tank body and extends outward; one end of the drain pipe absorbs water from the bottom of the tank body, and the other end is connected to the water pump; the drive shaft of the servo motor is connected to the rotating tank.

[0011] The lower end of the slag discharge pipe has a slag discharge port on its vertical wall; a cylindrical slider is rotatably connected to the upper end of the slag discharge pipe, with the slider end located inside the upper end of the limiting groove; the lower end of the slag discharge pipe is nested in the sleeve, allowing the slag discharge pipe to move up and down; the slag discharge pipe is connected to a hydraulic spring, and when the filter tank and the slag discharge pipe are filled with water, the hydraulic spring cannot support the slag discharge pipe, and a pin passes through the slag discharge pipe and the sleeve; the rotational speed of the servo motor is greater than the rebound speed of the hydraulic spring;

[0012] The baffle is tubular. After the baffle descends, it blocks the through-hole of the first partition. Multiple filter screens are provided on the baffle. The baffle is attached to the diversion tank, and the filter screens are attached to the opening on the diversion tank. The baffle is connected to the slag discharge pipe.

[0013] In one embodiment, the water level inside the tank is kept stable above the diversion tank by adjusting the inlet flow rate of the inlet pipe and the outlet flow rate of the outlet pipe.

[0014] In one embodiment, the inner wall of the tank is provided with a first mark and a second mark, wherein the first mark is located below the initial water level line and the second mark is located above the initial water level line. The operator can operate by observing the water level changes: when the water level drops to the first mark or rises to the second mark, backwashing and slag discharge operations can be carried out.

[0015] In one embodiment, the water level line is located at the first mark, indicating that the filter screen is clogged; the water level line is located at the second mark, indicating that too much gravel and silt have accumulated in the slag discharge pipe. In addition, if the filter screen is clogged and too much gravel and silt have accumulated in the slag discharge pipe at the same time, the water level line is located at the first mark.

[0016] In one embodiment, the bottom surface of the slag discharge pipe is provided with a conical protrusion, the top of which is a sharp corner, and the tank body 1 is located above the ground via a support plate 12.

[0017] In one embodiment, a waterproof micro-touch switch is provided on the bottom surface of the tank. When the slag discharge pipe moves downward to the maximum distance, the micro-touch switch is triggered. After the micro-touch switch is triggered, it transmits a signal to the microcontroller. The microcontroller first controls the servo motor to slow down its speed within a set time. At this time, the servo motor speed is less than the hydraulic spring rebound speed. After the set time ends, the servo motor speed is restored.

[0018] In one embodiment, after the micro-touch switch is triggered, the microcontroller controls the water pump power within a set time (after controlling the servo motor). After the backwashing and slag removal operations are completed, the water pump power is reduced so that the inflow rate is greater than the outflow rate, thereby allowing the tank water level to rise back to the normal height.

[0019] In one embodiment, the lower end of the slag discharge pipe has a rectangular cross-section, the sleeve has a rectangular cross-section, and the lower end of the slag discharge pipe is nested inside the sleeve, restricting the slag discharge pipe to only move up and down.

[0020] The beneficial effects of this invention are as follows:

[0021] (1) When the water level drops to the first mark, it indicates that multiple filter screens are blocked. Pull out the pin, the baffle drops down to change the water flow path, and the water in the upper cavity backwashes the multiple filter screens, thereby automatically cleaning the multiple filter screens inside the tank to reduce operating costs.

[0022] (2) When the water level rises to the second mark, it indicates that too much gravel and mud have accumulated in the slag discharge pipe. Pull out the pin, the slag discharge pipe descends, and the lower end moves out of the sleeve to open the slag discharge port, allowing the gravel and mud in the slag discharge pipe to be discharged along the slag discharge port. Thus, the staff can accurately judge whether slag discharge operation is needed by observing the changes in the water level. Attached Figure Description

[0034] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0035] Please see Figure 1-2 The present invention provides a rotary sediment separation irrigation device, comprising: a tank 1, a filter tank 2, a servo motor 3, a baffle 4, and a slag discharge pipe 5;

[0036] Please see Figure 1-2 The tank 1 is divided into an upper cavity 101 and a lower cavity 102 by a first partition 11. A through opening is provided on the axis of the first partition 11, which connects the upper cavity 101 and the lower cavity 102. The tank 1 is supported by a support plate 12 and is located above the ground. An observation port 13 is provided on the top surface of the tank 1 for staff to observe the water level changes inside the tank 1. A downwardly extending rectangular sleeve 16 is provided on the bottom surface of the tank 1.

[0037] Please see Figure 2-4The filter tank 2 is built inside the tank body 1. The filter tank 2 includes: a diversion tank 20, a rotating tank 21, and a limiting groove 22. The diversion tank 20 is located in the upper cavity 101 of the tank body 1 and is fixed to the top surface of the tank body 1. The diversion tank 20 is divided into a first cavity 201 and a second cavity 202 by a second partition. Both cavities have multiple openings 203 on their walls, which can communicate with the upper cavity 101. At the same time, the first cavity 201 and the second cavity 202 are connected along the axis, and a downward-extending pipe is provided on the bottom axis of the diversion tank 20. The diversion tank 20 and the rotating tank 21 are rotatably connected, and the whole structure is a through structure with the lower end in the shape of a frustum.

[0038] Please see Figure 2 , Figure 4 , Figure 7 The limiting groove 22 is located below the rotating tank 21. The limiting groove 22 is composed of a vertical groove 221 and a horizontal groove 222. Specifically, one end of the horizontal groove 222 is connected to the lower end of the vertical groove 221, and the top surface of the horizontal groove 222 is inclined.

[0039] Please see Figure 2-4 One end of the inlet pipe 14 penetrates downward through the diversion tank 20 and extends into the rotating tank 21, while the other end penetrates through the tank body 1 and extends outward. A valve 141 is provided on the inlet pipe 14 to control the water inlet. One end of the drain pipe 15 penetrates through the tank body 1 and extends into the interior, reaching the bottom of the tank body 1. The other end is connected to a water pump 151 to discharge water from the tank body 1. By adjusting the inlet flow rate of the inlet pipe 14 and the drain flow rate of the drain pipe 15, the water level in the tank body 1 is kept stably above the diversion tank 20. This water level is the normal height. The inner wall of the tank body 1 is provided with a first mark and a second mark (not shown in the figure), where the first mark is located below the normal height and the second mark is located above the normal height. The purpose of this is that the staff can operate by observing the water level changes: when the water level drops to the first mark or rises to the second mark, backwashing and slag removal operations can be carried out.

[0040] Please see Figure 1-4 The servo motor 3 is installed at the center of the top surface of the tank 1. The drive shaft 31 of the servo motor 3 extends downward and passes through the center of the tank 1, the diversion tank 20, and the rotating tank 21 respectively, and is connected to the rotating tank 21 through the support rod. The servo motor 3 drives the rotating tank 21 to rotate through the drive shaft 31. The rotation of the rotating tank 21 causes the water inside to rotate synchronously, forming a vortex. At this time, the gravel in the water will be thrown towards the side wall of the rotating tank 21 due to centrifugal force. The gravel thrown to the side wall will settle along the side wall under the action of gravity or the inertia of continuous rotation. The water with lower density will remain in the center area of ​​the vortex and eventually flow upward into the diversion tank 20, thereby completing the separation of gravel and water.

[0041] Please see Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 A slag discharge pipe 5 is installed in the lower cavity 102 of the tank body 1. The upper cross-section of the slag discharge pipe 5 is circular, and the lower cross-section is rectangular. A slag discharge port 51 is opened on the vertical wall of the lower end of the slag discharge pipe 5, and a conical protrusion 52 is provided on the bottom surface. The conical protrusion 52 is used to guide the gravel and silt to flow out along the slag discharge port 51. A bearing is installed inside the upper end of the slag discharge pipe 5, and a cylindrical slider 54 is configured on the bearing. Initially, the free end of the slider 54 is located in the upper end of the vertical groove 221, that is, the upper end of the slag discharge pipe 5 is slidably connected to the lower end of the filter tank 2. When the rotating tank 21 rotates, the limiting groove 22 drives the slag discharge pipe 5 to rotate. The slider 54 rotates synchronously; the lower end of the slag discharge pipe 5 is nested in the sleeve 16. On the one hand, the sleeve 16 blocks the slag discharge port 51, and on the other hand, it restricts the slag discharge pipe 5, allowing it to move only up and down; a hydraulic spring 50 is connected to one side of the slag discharge pipe 5. When the filter tank 2 and the slag discharge pipe 5 are filled with water, the slag discharge pipe 5 moves downward under the action of gravity, while the filter tank 2 does not move downward, compressing the hydraulic spring 50 connected to one side. At this time, the hydraulic spring 50 can no longer support it. The pin 53 passes through the slag discharge pipe 5 and the sleeve 16 to achieve the positioning of the slag discharge pipe 5.

[0042] Please see Figure 2-3 The baffle 4 is tubular, with a diameter larger than the through opening of the first partition 11, and is located in the upper cavity 101 of the tank body 1. The baffle 4 is provided with multiple filter screens 41, which initially correspond to multiple openings 203 on the first cavity 201. The baffle 4 blocks multiple openings 203 on the second cavity 202. The baffle 4 is connected to the slag discharge pipe 5 through multiple connecting rods 42, that is, the slag discharge pipe 5 and the baffle 4 move up and down synchronously.

[0043] Please see Figure 8 The arrows in the diagram indicate the direction of water flow. Water enters the rotating tank 21 through the inlet pipe 14, where centrifugal force generated by rotation separates the water from the gravel. The less dense water remains in the center of the vortex and flows upward into the diversion tank 20, completing the initial filtration. After the initial filtration, the water enters the first chamber 201 of the diversion tank 20 and passes through multiple filter screens 41 through multiple openings 203 on the wall of the first chamber 201, entering the upper chamber 101 to separate the water from the fine sediment, thus completing the secondary filtration. The water that has completed the secondary filtration flows downward to the lower chamber 102 of the tank 1 and is finally discharged through the drain pipe 15.

[0044] Please see Figure 2The bottom surface of the tank 1 is equipped with a waterproof micro-touch switch 10, which can be adapted to the water environment inside the tank 1. When the slag discharge pipe 5 moves downward to the maximum distance, the micro-touch switch 10 will be triggered. After the micro-touch switch 10 is triggered, it will transmit a signal to the microcontroller. The microcontroller will first control the servo motor 3 to slow down its speed within a set time (at this time, the speed of the servo motor 3 is less than the rebound speed of the hydraulic spring 50). After the set time ends, the speed of the servo motor 3 will be restored. At the same time, the power of the water pump 151 will be adjusted within the set time. After the backwashing and slag discharge operations are completed, the power of the water pump 151 will be reduced so that the inflow is greater than the outflow, thereby allowing the water level in the tank 1 to rise back to the normal height.

[0045] The purpose of setting the first and second markers is to determine the proportion of silt and gravel in the water. If the proportion of silt is high, it will quickly clog the filter screen 41. The clogging of the filter screen 41 reduces the outflow of water through the filter screen 41, causing the water level to drop to the first marker. If the proportion of gravel is high, it will cause gravel and silt to accumulate rapidly in the slag discharge pipe 5. Excessive accumulation will occupy the internal space of the slag discharge pipe 5. Since the inflow and outflow of water are stable, the water level will rise to the second marker. In addition, in practice, the clogging of the filter screen 41 and the excessive accumulation of gravel and silt in the slag discharge pipe 5 often occur simultaneously. Even so, the water level will still drop to the first marker because the outflow of water through the filter screen 41 is reduced. By observing the changes in the water level, the staff will clean the filter screen 41 and perform slag discharge operations.

[0046] Working principle of this invention:

[0047] Please see Figure 9 The arrows in the diagram indicate the direction of water flow. When the staff observes a change in the water level (i.e., the water level is at the first or second mark) through the observation port 13, they first close the valve 141 to stop the water supply to the rotating tank 21, and then pull out the pin 53 to release the positioning of the slag discharge pipe 5. Subsequently, the slag discharge pipe 5 moves the baffle 4 downwards in sync, and its lower end moves out of the sleeve 16 to open the slag discharge port 51, simultaneously triggering the micro-touch switch 10. At this time, multiple filter screens 41 are aligned with multiple openings 203 of the second cavity 202, and the lower end of the baffle 4 is aligned with... The top surface of the first partition 11 is attached to seal the through opening of the first partition 11. At this point, the water flow path changes, and the water in the upper cavity 101 flows into its interior through multiple openings 203 of the first cavity 201 and the second cavity 202. During the process, the water will carry the mud and sand blocked in the first cavity 201 to the slag discharge pipe 5, and at the same time, it will backwash multiple filter screens 41. The washed-off mud and sand will also flow into the slag discharge pipe 5. Finally, the gravel and mud and sand accumulated in the slag discharge pipe 5 will be discharged through the slag discharge port 51. During this process, it will not affect the irrigation of crops.

[0048] Please see Figure 10 The arrow in the diagram indicates the rotation direction of the limiting groove 22. During the downward movement of the slag discharge pipe 5, the slider 54 slides to the lower end of the vertical groove 221. Due to the rotation of the limiting groove 22, the slider 54 is nested within the horizontal groove 222. At this time, because the rebound speed of the hydraulic spring 50 is less than the rotation speed of the servo motor 3, the slider 54 remains within the horizontal groove 222 to limit the slag discharge pipe 5. Its function is to control the time of slag discharge from the filter screen 41. The aforementioned trigger micro-touch switch 10, after a certain period of time... The servo motor 3 slows down, so that the rebound speed of the hydraulic spring 50 is greater than the speed of the servo motor 3. The slider 54 rises along the inclined top surface of the horizontal groove 222 to the upper end of the vertical groove 221, that is, the slag discharge pipe 5 and the baffle 4 return to the initial height. The servo motor 3 returns to the initial speed, the valve 141 is opened, and water supply to the rotating tank 21 is restarted. The power of the water pump 151 is reduced, so that the inflow is greater than the outflow, thereby allowing the water level in the tank 1 to rise back to the normal height. After that, the water pump 151 returns to the initial power.
