Technical Field

[0001] This utility model relates to the field of plant cultivation technology, specifically a filter for an integrated drip irrigation device for plant cultivation. Background Technology

[0002] Plant cultivation is an agricultural activity that involves artificially selecting and preserving beneficial variations while eliminating unfavorable ones to form plant populations with stable genetic traits. During plant cultivation, to precisely control water and fertilizer supply, achieve water and fertilizer conservation, and improve crop yield and quality, integrated water and fertilizer drip irrigation devices are needed for irrigation and fertilization. However, the water used for irrigation is mostly river water or groundwater. To reduce the probability of sediment clogging the drip irrigation heads, filters are needed to filter the irrigation water. In the existing technology, patent publication number CN 223026867 U proposes a drip irrigation filter, including an inlet, a tank, a tank cover, and an outlet. The inlet and outlet are connected to the inner cavity of the tank. The tank cover is detachably installed on the top of the tank. A retaining ring is provided at the bottom of the inner cavity of the tank, and a lifting basket is provided on the retaining ring. A filter layer is provided inside the lifting basket, and a movable rod is provided on the upper surface of the filter layer. The movable rod is slidably connected to a guide cylinder. Although this filter can filter irrigation water, the filtered sediment particles accumulate inside the filter components, requiring frequent cleaning of the filter, making it inconvenient to use. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a filter for a drip irrigation device for integrated water and fertilizer in plant cultivation. The filter guides the sediment particles from the two filtrations to be stored inside the sedimentation tank, reducing the rate at which sediment particles accumulate on the surface of the filter components and reducing the frequency of filter cleaning. This can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a filter for a drip irrigation device for integrated water and fertilizer in plant cultivation, including a centrifugal filter cylinder, a water pipe provided at the outlet on the upper surface of the centrifugal filter cylinder, filter cylinders connected in series in the middle of the water pipe, a filter screen provided between the upper and lower inner walls of the filter cylinder, and a collection mechanism. Collection mechanism: It includes a sedimentation tank, a connecting pipe, and a baffle. The sedimentation tank is located at the sand outlet at the lower end of the centrifugal filter cylinder. The collection port on the outer arc surface of the sedimentation tank is connected to the collection pipe at the lower end of the outer arc surface of the filter cylinder through the connecting pipe. The sedimentation tank is rotatably connected to the baffle, which guides the silt particles filtered twice to be stored inside the sedimentation tank, reducing the speed at which silt particles accumulate on the surface of the filter components, reducing the frequency of filter cleaning, and can clean the silt particles filtered twice at the same time, reducing the time required for subsequent filter cleaning, making the use of the filter of the integrated water and fertilizer drip irrigation device for plant cultivation more convenient.

[0005] Furthermore, the collection mechanism also includes arc-shaped plates and connecting holes. The arc-shaped plates are respectively disposed on the surface of the partition. The outer arc surface of the arc-shaped plates is in contact with the inner arc surface of the sedimentation tank. The outer arc surface of the arc-shaped plates is provided with connecting holes that are installed in conjunction with connecting pipes, so that the connecting pipes are sealed during sediment removal.

[0006] Furthermore, the collection mechanism also includes a rotating column and a tank cover. The rotating column is located in the middle of the partition, the rear end of the sedimentation tank has an open structure, and the rear end of the sedimentation tank is provided with a tank cover.

[0007] Furthermore, the collection mechanism also includes a positioning plate, which is longitudinally slidably connected to the surface of the outer hexagonal column at the rear end of the rotating column. The positioning plate engages with the slot at the rear end of the can lid to fix the angle of the partition.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-5 This embodiment provides a technical solution: a filter for an integrated water and fertilizer drip irrigation device for plant cultivation, including a centrifugal filter cylinder 1. A water pipe 2 is provided at the outlet on the upper surface of the centrifugal filter cylinder 1. Filter cylinders 3 are connected in series in the middle of the water pipe 2. Filter screens 4 are provided between the upper and lower inner walls of the filter cylinders 3. During plant cultivation, the entire device is connected in series in the middle of the water supply pipeline of the integrated water and fertilizer drip irrigation device. During water delivery, the water flows tangentially into the centrifugal filter cylinder 1 through the inlet pipe, forming a high-speed rotating vortex. Under the action of centrifugal force, the denser mud... Sand particles are thrown against the pipe wall and move downwards along the wall of the centrifugal filter cylinder 1, while relatively clean water flows out from the water pipe 2 and enters the filter cylinder 3 to perform primary filtration of the mud and sand particles in the water, intercepting mud and sand particles larger than or equal to 75 microns. Then, the filter screen 4 is used for secondary filtration of the mud and sand particles in the water flow, intercepting mud and sand particles of 10-400 microns. Finally, the filtered water flows out from the lower end of the water pipe 2. The cylinder cover at the top of the filter cylinder 3 is removed periodically to replace or clean the filter screen 4 to ensure the normal operation of the filter screen 4. The filter screen 4 can be a stainless steel filter screen and also includes a collection mechanism 5. Collection mechanism 5: It includes a sedimentation tank 51, a connecting pipe 52, and a baffle 53. The sedimentation tank 51 is located at the sand outlet at the lower end of the centrifugal filter cylinder 1. The collection port on the outer arc surface of the sedimentation tank 51 is connected to the collection pipe at the lower end of the outer arc surface of the filter cylinder 3 through the connecting pipe 52. The baffle 53 is rotatably connected inside the sedimentation tank 51. The mud and sand particles moving downward along the wall of the centrifugal filter cylinder 1 are finally deposited in the sedimentation tank 51. The mud and sand particles intercepted by the filter screen 4 will be deposited at the lower end of the filter cylinder 3. The mud and sand particles deposited at the lower end of the filter cylinder 3 enter the interior of the sedimentation tank 51 through the connecting pipe 52. The baffle 53 divides the interior of the sedimentation tank 51 into two spaces to store the mud and sand particles filtered in the first and second filtrations, respectively, while preventing the water inside the filter cylinder 3 from flowing back into the centrifugal filter cylinder 1. The collection mechanism 5 also includes an arc plate 55 and a connecting hole 56. The arc plate 55 is respectively set on the surface of the partition 53. The outer arc surface of the arc plate 55 is in contact with the inner arc surface of the sedimentation tank 51. The outer arc surface of the arc plate 55 is provided with a connecting hole 56 that is installed in conjunction with the connecting pipe 52. During the filtration process, the connecting hole 56 coincides with the connecting pipe 52. The sediment particles filtered in the second stage can enter the sedimentation tank 51 through the connecting pipe 52. When it is necessary to clean the inside of the sedimentation tank 51, the partition 53 drives the arc plate 55 to rotate. During the rotation, the connecting hole 56 is first misaligned with the connecting pipe 52. The arc plate 55 blocks the left end of the connecting pipe 52. Then, as the partition 53 continues to rotate, the space where the sediment particles are located in the second stage is connected to the inside of the centrifugal filter cylinder 1, so as to prevent the water inside the filter cylinder 3 from flowing back into the centrifugal filter cylinder 1 when the sediment is cleaned. The collection mechanism 5 also includes a rotating column 54 and a tank cover 58. The rotating column 54 is located in the middle of the partition plate 53. The rear end of the sedimentation tank 51 is an open structure. The rear end of the sedimentation tank 51 is provided with a tank cover 58. The rear end of the rotating column 54 is rotatably connected to the rotating hole in the middle of the tank cover 58, providing rotational support for the partition plate 53. This facilitates the installation of the partition plate 53 inside the sedimentation tank 51. The tank cover 58 is periodically removed, and the partition plate 53 is taken out for maintenance. The accumulation of mud and sand on the surface of the partition plate 53 affects normal operation. The collection mechanism 5 also includes a positioning plate 57, which is longitudinally slidably connected to the outer hexagonal column surface at the rear end of the rotating column 54. The positioning plate 57 engages with the slot at the rear end of the tank cover 58. When the positioning plate 57 engages with the slot at the oblique end of the tank cover 58, the rotating column 54 is restricted to an inclined state. At this time, only the space where the primary filtered sediment particles are located is connected to the interior of the centrifugal filter cylinder 1. When the positioning plate 57 engages with the slot at the vertical end of the tank cover 58, the partition 53 is kept in a vertical state. At this time, both the space where the secondary filtered sediment particles are located and the space where the primary filtered sediment particles are located are connected to the interior of the centrifugal filter cylinder 1. The collecting mechanism 5 also includes a limiting nut 59, which is threaded to the outer arc surface of the stud at the rear end of the rotating column 54. The limiting nut 59 is movably sleeved on the outer hexagonal column surface of the rotating column 54. The rear side of the limiting nut 59 contacts the surface of the positioning plate 57, thereby restricting the forward and backward movement of the positioning plate 57 and preventing the positioning plate 57 from leaving the slot. The front end of the cleaning pipe of the settling tank 51 is equipped with a cover 6, and the observation window in the middle of the cover 6 is equipped with transparent glass 7, which makes it convenient to observe the amount of mud and sand particles inside the settling tank 51. All filter screens 4 are conical filter screens, and the diameter of filter screen 4 gradually decreases from top to bottom, so that the filtered mud and sand can fall more smoothly along the conical arc surface of filter screen 4.

[0016] The working principle of the filter in the integrated water and fertilizer drip irrigation device for plant cultivation provided by this utility model is as follows: During plant cultivation, the entire device is connected in series in the middle of the water supply pipeline of the integrated water and fertilizer drip irrigation device. During water delivery, the water flows tangentially into the centrifugal filter cylinder 1 through the inlet pipe, forming a high-speed rotating vortex. Under the action of centrifugal force, the denser silt particles are thrown against the pipe wall and move downward along the wall of the centrifugal filter cylinder 1, eventually settling in the sedimentation tank 51. Meanwhile, the cleaner water flows out from the water pipe 2 and enters the filter cylinder 3. Inside, filter screen 4 further intercepts sediment particles in the water flow. The filtered water is then discharged from the lower end of water pipe 2. The intercepted sediment particles are deposited along the conical arc surface of filter screen 4 at the lower end of filter cylinder 3. At this point, the connecting hole 56 coincides with the connecting pipe 52. The sediment particles deposited at the lower end of filter cylinder 3 enter the sediment settling tank 51 through the connecting pipe 52. A partition 53 divides the interior of sediment settling tank 51 into two spaces, storing the sediment particles from the first and second filtration processes respectively, while preventing water from flowing back into centrifugal filter cylinder 1. When it is necessary to clean the sediment particles inside the sedimentation tank 51, rotate the limiting nut 59. Through the threaded connection between the limiting nut 59 and the rotating column 54, the limiting nut 59 moves forward, releasing the limiting effect on the positioning plate 57. At this time, the positioning plate 57 can be pulled out from the inclined groove at the rear end of the tank cover 58, releasing the limiting effect on the rotating column 54. Then, the rotating column 54 can be rotated using an external wrench or other tools, causing the partition plate 53 and the arc plate 55 to rotate inside the sedimentation tank 51. During the rotation, the connecting hole 56 is first misaligned with the connecting pipe 52, and the arc plate 55 is used to seal the left end of the connecting pipe 52. Then, as the partition 53 continues to rotate, when the positioning plate 57 coincides with the vertical groove at the rear end of the tank cover 58, stop rotating the rotating column 54, push the positioning plate 57 to engage with the vertical groove of the tank cover 58, and maintain the angle of the partition 53. At this time, the space where the secondary filtered sediment particles are located and the space where the primary filtered sediment particles are located are both connected to the inside of the centrifugal filter cylinder 1. Stop rotating, and finally open the cover 6 to allow the water inside the centrifugal filter cylinder 1 to flow into the sedimentation tank 51 and drive the sediment particles inside the sedimentation tank 51 to be discharged. After the discharge is completed, repeat the above operation in reverse to reset the partition 53.

[0017] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
