Background Art

Farmland irrigation is a common method to alleviate the problem of farmland drought. With the deepening of environmental awareness, the traditional flooding method has been changed to irrigation with pipe laying. Even drip irrigation and micro-irrigation have been widely used in water-deficient areas in recent years. If the pipe is not filtered during the water delivery process, it is easy to be blocked by sand and gravel, especially in the application of drip irrigation and micro-irrigation, the requirements for irrigation water are higher. Therefore, the irrigation equipment is required to be equipped with a filtering function.

Before the water flows into the pipeline, a filter tank is usually set up to precipitate and filter the water to reduce impurities in the water. However, during the filtration and precipitation process, impurities will be embedded in the filter holes and clogged, and precipitate at the bottom of the sedimentation tank. In the related technology, the Chinese patent document with application number CN201920585043.9 provides an irrigation water filtration device, which uses backwash water to flush and drain the filter tank, and uses a scraper to scrape the sediment in the sedimentation tank. However, the shape of the scraper and the precipitated sand are difficult to clean due to the effect of water. The stretch scraper may bounce with resistance and not be cleaned thoroughly. It is difficult to clean the debris stuck in the filter holes by only relying on water flow to clean the filter tank.

DETAILED DESCRIPTION

In order to make it easier to understand the structure of the present invention and the functional features and advantages that can be achieved, the preferred embodiments of the present invention are described in detail with reference to the drawings as follows:

Example:

As shown in Figures 1 to 3, the utility model provides an irrigation device with a filtering function, including a box body 1, an inlet pipe 14 and an outlet pipe 15, the inlet pipe 14 and the outlet pipe 15 are arranged on both sides of the box body 1, a first sedimentation tank 11 and a second sedimentation tank 12 are arranged in the box body 1, the first sedimentation tank 11 and the second sedimentation tank 12 are separated by a partition plate 13, the first sedimentation tank 11 and the second sedimentation tank 12 are both provided with a sewage outlet 17, a first filter group 2 and a second filter group 3 are also arranged in the box body 1, the first filter group 2 is arranged below the inlet pipe 14 and is rotatably connected to the side wall of the box body 1, the second filter group 3 is arranged on the top of the partition plate 13, and also includes a swing mechanism 4 for shaking the first filter group 2, and a stirring mechanism 5 for cleaning impurities in the first sedimentation tank 11. The vertical section of the partition plate 13 is an arched structure.

The water inlet pipe 14 is located above the first sedimentation tank 11 and the first filter group 2. At this time, the water first passes through the first filter group 2 to filter out larger impurities, and then enters the first sedimentation tank 11 for sedimentation. When the water level in the first sedimentation tank 11 rises to the top of the partition plate 13, the water passes through the second filter group 3 for more detailed filtration, and then enters the second sedimentation tank 12 for secondary sedimentation. The outlet position of the water outlet pipe 15 is lower than the highest point of the partition plate 13 to prevent the water in the first sedimentation tank 11 and the second sedimentation tank 12 from mixing again. When there are too many sediments in the first sedimentation tank 11 and the second sedimentation tank 12, the stirring mechanism 5 is turned on to stir the sediment and water in the first sedimentation tank 11 so that the sediment is discharged from the sewage outlet 17 along the water flow. The shaking mechanism 4 can also be opened when the stirring mechanism 5 stirs the first sedimentation tank 11, so that the impurities embedded in the filter holes of the first filter group 2 can be shaken off and discharged from the first sedimentation tank 11 along with the water flow. The shaking mechanism 4 can also be opened when the water inlet pipe 14 is fed with water. Shaking during the filtration process can effectively reduce the impurities stuck in the filter holes and speed up the filtration speed. Since the water in the second sedimentation tank 12 is filtered and precipitated once by the first filter group 2 and the second filter group 3 and both sides of the first sedimentation tank 11, the impurities precipitated in the second sedimentation tank 12 are reduced and mostly suspended matter. Therefore, the stirring mechanism 5 is not set again in the first sedimentation tank 11. If there is a need during use, the stirring mechanism 5 can also be set in the first sedimentation tank 11. The sewage outlet at the first sedimentation tank 11 can be set on the side wall or bottom wall of the box body 1, and the sewage outlet at the second sedimentation tank 12 is set on the bottom wall of the box body 1 at the second sedimentation tank 12, which is the best solution. The vertical cross section of the partition plate 13 is arched. When the water level exceeds the partition plate 13 and flows into the second sedimentation tank 12, the arch can slow down the water flow speed and enhance the sedimentation effect.

As another embodiment, as shown in FIGS. 2 to 4 , the first filter group 2 of the present application includes a multi-stage filter screen 22, wherein the multi-stage filter screen 22 is provided with multiple layers of filter screens spaced from the inside to the outside, and the filter hole diameter decreases layer by layer from the inside to the outside, and the multi-stage filter screen 22 is rotatably connected to the side wall of the box body 1 through a rotating shaft 21. The swing mechanism 4 includes a base 41, a first motor 42, an active rod 43, a driven rod 44 and a connecting rod 45, wherein the base 41 is fixed to the outer wall of the box body 1, one end of the active rod 43 is rotatably connected to the base 41 and is coaxially connected to the output end of the first motor 42, the other end of the active rod 43 is movably connected to the lower end of the driven rod 44, the upper end of the driven rod 44 is fixedly connected to one end of the connecting rod 45, the other end of the connecting rod 45 passes through the side wall of the box body 1 and is snap-connected to one side of the multi-stage filter screen 22, and a slot 16 is provided on the side wall of the box body 1, and the connecting rod 45 moves up and down in the slot 16.

There are gaps between the multi-stage filter screens 22, and the water flows through the innermost filter screen first. The innermost filter screen has the largest filter holes, and the filter holes of the filter screens gradually become smaller from the inside to the outside. The specific number of layers is based on the use, and can be three layers, four layers, etc. The three-layer filter screen is shown in the drawings of this application. The center of one side of the multi-stage filter screen 22 is coaxial with the rotating shaft 21, and the multi-stage filter screen 22 can be sleeved on the rotating shaft 21, such as fixing a sleeve on one side of the multi-stage filter screen 22, and the sleeve is sleeved on the rotating shaft 21, so that the multi-stage filter screen 22 can rotate on the rotating shaft 21. The operation of the swing mechanism 4 is to fix the first motor 42 with the base, and the output end of the first motor 42 is fixedly connected to one end of the active rod 43. At this time, when the output end of the first motor 42 rotates, the active rod 43 rotates with the output end of the first motor 42. The connection between the driven rod 43 and the active rod 43 is a rotation connection. When the active rod 43 moves, the driven rod 43 drives the connecting rod 45 to move up and down. The connecting rod 45 is snap-connected with the multi-stage filter 22. A sleeve can be set in the multi-stage filter 22, and one end of the connecting rod 45 is inserted into the sleeve set in the multi-stage filter 22, or other structures that can snap the multi-stage filter 22 with the connecting rod 45. Therefore, when the connecting rod 45 moves up and down, it drives the multi-stage filter 22 to move up and down. The connecting rod 45 is connected to one side or one corner of the multi-stage filter 22. At this time, the multi-stage filter 22 swings up and down with the connecting rod 45 with the rotating shaft 21 as the axis. Since the multi-stage filter screen 22 can be sleeved on the rotating shaft 21, the multi-stage filter screen 22 can be slid out of the rotating shaft 21 when cleaning. Since the multi-stage filter screen 22 is always in a shaking state during the water filtering process, it is difficult for impurities to adhere to the multi-stage filter screen 22 or get stuck in the filter holes. Therefore, when cleaning, it is only necessary to pour out the impurities in the multi-stage filter screen 22, and the cleaning process is effective and convenient.

As another embodiment, as shown in FIG. 3 , the second filter group 3 of the present application includes a fixing frame 31 and a water filter cloth 32 , and the water filter cloth 32 is mounted on the inner wall of the fixing frame 31 .

The fixing frame 31 is fixed to the top of the partition plate 13. The fixing frame 31 of the present application is preferably made of metal material: an iron frame or a steel frame. The water filter cloth 32 can be provided with multiple layers. The water filter cloth 32 is made of cloth with small density gap and high corrosion resistance, such as polytetrafluoroethylene (PTFE) cloth, etc. If cost is considered, ordinary cloth strips can also be used. The water filter cloth 32 is vertically hung on the fixing frame 31 and fixed by the fixing frame 31.

As another embodiment, as shown in Figs. 1 to 3 and 5, the stirring mechanism 5 of the present application includes a rotating wheel 51, a second motor 52, a driving wheel 53 and a driven wheel 54, the rotating wheel 51 runs through the first sedimentation tank 11, and one end of the rotating wheel 51 passes through the side of the box body 1 close to the sewage outlet 17, the other end of the rotating wheel 51 passes through the partition plate 13 and extends into the partition plate 13, the output end of the second motor 52 is fixedly connected to the center of the driving wheel 53, the teeth of the driven wheel 54 are meshed with the teeth of the driving wheel 53, and the center of the driven wheel 54 is fixedly connected to the center of the rotating wheel 51. The surface of the rotating wheel 51 is provided with stirring blades 54, and the setting direction of the stirring blades 54 is consistent with the direction of the rotating wheel 51.

The output end of the second motor 52 rotates, driving the driving wheel 53 to rotate, and the driving wheel 53 rotates to drive the driven wheel 54 to rotate with the driving wheel 53. There can be multiple driven wheels 54. The number of the running wheel 51 is determined according to the size of the first sedimentation tank 11 and the size of the running wheel 51 and the stirring blades 54. The number of driven wheels 54 corresponds to the running wheel 51. The stirring blades 54 can be straight plates set along the length of the running wheel, or they can be spiral-shaped. When the stirring blades 54 are spiral-shaped, it is convenient to take the debris out of the first sedimentation tank 11 through rotation. The ends of the stirring blades 54 can also be connected to rubber strips to reduce wear during long-term rotation.

As another embodiment, as shown in FIG3 , the sewage outlet 17 of the present application is opened at the bottom of the side wall of the first sedimentation tank 11 and the bottom of the second sedimentation tank 12, and the sewage outlet is fixedly connected with a sealing strip 18. The sewage outlet 17 at the first sedimentation tank 11 is set at the bottom of the side wall or the bottom wall, and the sewage outlet 17 at the second sedimentation tank 12 is set at the bottom wall, because the sediment in the second sedimentation tank 12 is mostly suspended matter with a light mass, and the sewage outlet 17 can flow out with the water flow when it is opened. The sealing strip 18 is a rubber strip.

The present application discloses an irrigation device with filtering function, and its working principle is as follows: a water pump draws water into a housing 1 through a water inlet pipe 14, first passes through a first filter group 2, and then passes through a multi-stage filter screen 22 whose pore size gradually decreases with each level. During this process, the first filter group 2 is controlled by a swing mechanism 4 to shake, which speeds up filtering on the one hand, and reduces the probability of impurities blocking the holes of the multi-stage filter screen 22 on the other hand. After the water flows through the multi-stage filter screen 22, it enters a first sedimentation tank 11 for sedimentation. After the water level exceeds the top of a partition plate 13, it passes through a water filter cloth 32 in a fixed frame 31 for further filtration, and then enters a second sedimentation tank 12 for a second sedimentation. When the water level reaches an outlet pipe 15, it is discharged from the outlet pipe 15. When cleaning is required, the multi-stage filter screen 22 can be directly slid out of the first sedimentation tank and simply dumped, because the impurities in the multi-stage filter screen 22 are always in motion during the shaking process and are not easy to adhere to the multi-stage filter screen 22. The stirring mechanism 5 then stirs the water and impurities settled at the bottom of the first sedimentation tank 11, opens the drain port 17, and uses the buoyancy of the water to discharge the sewage and impurities out of the first sedimentation tank 11 together. The drain port 17 is opened to discharge the water and sediment in the second sedimentation tank 12 out of the second sedimentation tank 12. The edge of the drain port 17 is fixedly connected to the sealing strip 18, and the sealing strip 18 plays a sealing role after closing the drain port 17. The impurities in the multi-stage filter screen 22 are discharged together with the impurities in the first sedimentation tank 11, and the multi-stage filter screen 22 can be turned over and shaken, which effectively reduces the stubborn impurities on the multi-stage filter screen 22. The stirring mechanism 5 stirs the water and sediment and then discharges them, and uses the fluidity of water to remove the stubborn precipitated impurities in the first sedimentation tank 11 together, effectively improving the impurity discharge capacity.

The above are only preferred embodiments of the present invention, and do not limit the present invention in any form. Any technician familiar with the field can make many possible changes and modifications to the technical solution of the present invention by using the above technical content without departing from the scope of the technical solution of the present invention, or modify it into an equivalent embodiment of equivalent changes.
