Description

Technical Field

[0001] This utility model relates to the field of drip irrigation technology, and in particular to a pre-pump filter for a drip irrigation system. Background Technology

[0002] Drip irrigation is a precision irrigation method that delivers water to the soil near the crop roots through a network of pipes, dripping it at a constant, low rate. This method ensures that water reaches the plant root zone directly, reducing waste caused by evaporation, runoff, and deep seepage.

[0003] Drip irrigation works by controlling the water flow rate, allowing it to flow into the soil at a very slow and even speed. This allows the soil to absorb the water slowly without causing rapid water loss. Typically, drip irrigation systems use low-pressure pipes to deliver water, which is then dripped into the soil through emitters or drip tape (soft tubing with micropores) installed on the pipes.

[0004] Because drip irrigation systems have numerous pipes, and the water droplets on the terminal pipes are seepage drips, the water used in drip irrigation systems must reach a certain level of cleanliness to avoid pipe leakage and blockage. Even though drip irrigation systems are more water-saving than conventional irrigation systems, they still require a huge amount of water to complete the dripping process. This causes conventional filters to become clogged after a period of use due to the excessive impurities trapped in the filter components. Therefore, filter components need to be replaced regularly. However, replacing filter components causes the water supply to stop, which can easily affect the efficiency of drip irrigation. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a pre-pump filter for a drip irrigation system, which solves the technical problem that water supply stops due to the periodic replacement of filter components, thereby affecting the efficiency of the drip irrigation system.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0009] This utility model provides a pre-pump filter for a drip irrigation system, including a vertically arranged filter tank, an inlet pipe at the top of the filter tank, an outlet pipe at the bottom of the filter tank, and multiple layers of filter media horizontally arranged inside the filter tank. The multiple layers of filter media are evenly spaced from top to bottom. The side of the filter tank has horizontally spaced through holes evenly spaced along the vertical direction. A bracket is slidably and sealed inside the through hole. The bracket has two vertical mounting holes arranged side by side along the sliding direction for embedding the same type of filter media layer. When any set of mounting holes arranged in the vertical direction of the filter tank is aligned with the inlet pipe and a set of filter media layers is installed, the water flow is filtered.

[0010] This utility model proposes a pre-pump filter for a drip irrigation system. When using this filter, the filter media layers are embedded one by one into the mounting holes of the insert. Then, the insert is slid to insert the side with the installed filter media layers into the through hole. The water pipe is then directly connected to the inlet pipe, and the water flows into the filter tank. The water flows through the layers of filter media and then flows out through the outlet pipe at the bottom and into the drip system. The filter media layers are then embedded again into the mounting holes on the exposed side of the insert. After a period of time, the insert is slid horizontally to insert the unused filter media layers into the filter tank. The process does not require stopping the water supply, thus completing the replacement of the filter components. The used filter media layers are then replaced for later use. This solution allows for the replacement of filter components without stopping the water supply, thereby achieving continuous drip irrigation and higher efficiency.

[0011] Optionally, both ends of the insert are provided with limiting plates that slide and abut against the side of the filter water tank, and the end face of the limiting plate away from the insert is provided with a single pull handle.

[0012] By setting limiting plates on both sides of the insert holder and installing single pull handles on the limiting plates, the insert holder can be pulled to the accurate position without positioning when sliding horizontally, which is more convenient.

[0013] Optionally, both sides of the filter tank are provided with a sliding pull plate, and the sliding pull plate has a sleeve hole of the same size that is aligned with the multiple through holes. The two sides of the insert are slidably inserted into the sleeve hole, and the limiting plate abuts against the end of the sliding pull plate away from the filter tank. The ends of the two sliding pull plates that are far apart from each other are provided with a pull handle, and the sliding pull plate drives all the inserts to slide.

[0014] By setting up a synchronized pull plate, when replacing the filter media layer, the same pull handle can be pulled directly, allowing the synchronized pull plate to move all the inserts synchronously, thus quickly completing the replacement of the filter media layer, which is more convenient.

[0015] Optionally, the upper and lower end faces of the insert are bonded with a sealing adhesive layer to seal the through holes around the two mounting holes.

[0016] By setting a sealing layer at both ends of the insert holder, the sealing layer can abut against the inner wall of the through hole to a certain extent when the insert holder slides to the two work positions, thereby reducing water outflow and reducing water waste.

[0017] Optionally, a quick-change component is detachably connected to the side of the filter tank, and the quick-change component can simultaneously disassemble one set of the filter media layers.

[0018] By detachably connecting the quick-change component to the side of the filter tank, the used filter media layer can be removed at once when changing the filter media layer, making it more convenient and faster.

[0019] Optionally, the quick-change component includes a long rod, short rods arranged at uniform vertical intervals along the length of the long rod, a bent rod vertically downward disposed at the end of the short rod away from the long rod, a plate horizontally disposed at the end of the bent rod away from the short rod, and a vertical array of staples disposed on the lower end face of the plate. The staples are attached to the filter media layer and carry the filter media layer out of the mounting hole.

[0020] By holding the long rod vertically, each plate is positioned on top of each filter media layer. Then, the long rod is moved vertically downwards, causing the pins on the plates to drive directly into the filter media layer. Next, the long rod is moved upwards, causing the filter media layer to come out of the mounting hole. Finally, the long rod is moved horizontally, allowing all the used filter media layers to be removed. This method makes the removal of filter media layers much more convenient.

[0021] Optionally, a hanging ring is provided at the top of the side end of the filter tank, and a hook is provided at the top of the long rod to be hooked onto the hanging ring.

[0022] By installing a hanging ring on the side of the filter tank, the hook at the top of the long rod can be directly hooked onto the hanging ring, making it more convenient to access and place the quick-change component.

[0023] Optionally, the side of the filter tank is provided with multiple sets of discharge rods evenly spaced from top to bottom. Each set of discharge rods includes multiple rods arranged in parallel at intervals. The discharge rods are inserted between the filter media layer and the plate and separate the filter media layer and the plate. The side of the filter tank is provided with a sliding plate that receives the filter media layer as it slides down, located at the lower side of each set of discharge rods. The side of the filter tank is provided with a waste box that receives the filter media layer, located at the lowermost discharge rod.

[0024] By setting up a discharge rod, after the filter media layer is removed via the quick-change assembly, the quick-change assembly is moved to the side of the filter tank. Then, the long rod is moved until the discharge rod is inserted between the filter media layer and the plate. The long rod is then moved upwards, causing the filter media layer to separate from the staples and fall onto the slide plate. Finally, it slides down the slide plate into the waste box. This solution allows operators to easily collect the used filter media layer without directly contacting it, making it more convenient.

[0025] Optionally, a water-dividing nozzle is provided at the top of the filter tank. One end of the water-dividing nozzle is connected to the water inlet pipe, and the other end of the water-dividing nozzle has the same cross-sectional size as the filter media layer in the horizontal direction. Water-dividing holes are evenly arrayed on the water-dividing nozzle.

[0026] By setting up water distribution nozzles, the water flowing in along the inlet pipe can enter the filter tank more evenly after passing through the water distribution nozzles and come into contact with the filter media layer, thereby improving the service life of the filter media layer.

[0027] (III) Beneficial Effects

[0028] The beneficial effects of this utility model are as follows: The pre-pump filter of this utility model for drip irrigation systems, when used, involves embedding the filter media layers one by one into the mounting holes of the insert. Then, the insert is slid to insert the side with the installed filter media layer into the through hole. The water pipe is then directly connected to the inlet pipe, and the water flows into the filter tank. The water flows through the layers of filter media and then out through the outlet pipe at the bottom into the drip system. The filter media layer is then embedded again into the mounting hole on the exposed side of the insert. After a period of time, the insert is slid horizontally to insert the unused filter media layer into the filter tank. This process does not require stopping the water supply, thus completing the replacement of the filter components. The used filter media layer is then replaced for later use. This solution allows for continuous drip irrigation without stopping the water supply when replacing filter components, resulting in higher efficiency. Attached Figure Description

[0035] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] The pre-pump filter for the drip irrigation system proposed in this embodiment involves embedding the filter media layers one by one into the mounting holes of the insert. The insert is then slid to insert the side with the installed filter media layers into the through-hole. A water pipe is then directly connected to the inlet pipe, allowing water to flow into the filter tank. The water flows through the layers of filter media and then out through the bottom outlet pipe into the drip irrigation system. The filter media layers are then re-embedded into the mounting holes on the exposed side of the insert. After a period of time, the insert is slid horizontally to insert the unused filter media layers into the filter tank. This process does not require stopping the water supply, thus completing the replacement of the filter components. The used filter media layers are then replaced for later use. This solution allows for continuous drip irrigation without stopping the water supply, resulting in higher efficiency.

[0037] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0038] Reference Figure 1 A pre-pump filter for a drip irrigation system includes a vertically arranged filter tank 1, an inlet pipe 2 located at the top of the filter tank 1, an outlet pipe 3 located at the bottom of the filter tank 1, and a multi-layer filter media layer 4 horizontally arranged inside the filter tank 1, wherein the multi-layer filter media layer 4 is evenly spaced from top to bottom.

[0039] See Figure 1 and Figure 2The side of the filter tank 1 has horizontally spaced through holes 11 evenly spaced in the vertical direction. A bracket 5 is slidably and sealed inside the through hole 11. The bracket 5 has two vertically spaced mounting holes 51 arranged in parallel along the sliding direction for embedding the same type of filter media layer 4. When any set of mounting holes 51 arranged in the vertical direction of the filter tank 1 is aligned with the water inlet pipe 2 and a set of filter media layers 4 is installed, the water flow is filtered. When using this filter, the filter media layers 4 are inserted one by one into the mounting holes 51 of the insert 5. Then, the insert 5 is slid to insert the side with the filter media layers 4 installed into the through hole 11. Then, the water pipe is directly connected to the inlet pipe 2, and the water flows into the filter tank 1. The water flows through the layers of filter media layers 4 and then flows out through the outlet pipe 3 at the bottom and into the drip system. Then, the filter media layers 4 are inserted into the mounting holes 51 on the exposed side of the insert 5. After a period of time, the insert 5 is slid horizontally so that the unused filter media layers 4 are inserted into the filter tank 1. The water supply does not need to be stopped during the process, thus completing the replacement of the filter components. Then, the used filter media layers 4 are replaced for later use.

[0040] The insert bracket 5 has vertically welded limit plates 52 on both sides, which slide and abut against the side of the filter water tank 1. The end face of the limit plate 52 away from the insert bracket 5 is fixed with a single pull handle 53 by bolts. This makes it more convenient to pull the insert bracket 5 to the accurate position without positioning when sliding it horizontally.

[0041] Both sides of the filter tank 1 are equipped with movable pull plates 54. Each movable pull plate 54 has a sleeve hole 541 of the same size aligned with multiple through holes 11. The two ends of the insert brackets 5 slide into the sleeve holes 541. A limiting plate 52 abuts against the end of the movable pull plate 54 furthest from the filter tank 1. A pull handle 542 is provided at the ends of the two movable pull plates 54 that are furthest from each other. The movable pull plates 54 drive all the insert brackets 5 to slide. The pull handle 542 can be pulled directly, allowing the movable pull plates 54 to move all the insert brackets 5 synchronously, thus quickly completing the replacement of the filter media layer 4.

[0042] The upper and lower end faces of the insert 5 are bonded with a sealing layer 55 for sealing through holes 11 on the outer periphery of the two mounting holes 51. This allows the sealing layer 55 to abut against the inner wall of the through hole 11 to a certain extent when the insert 5 slides to the two positions.

[0043] See Figure 3The side end of the filter tank 1 is detachably connected to a quick-change assembly 6. The quick-change assembly 6 can simultaneously remove a set of filter media layers 4. The quick-change assembly 6 includes a long rod 61, short rods 62 that are evenly and vertically spaced along the length of the long rod 61, a bent rod 63 that is vertically downward set at the end of the short rod 62 away from the long rod 61, a plate 64 that is horizontally welded to the end of the bent rod 63 away from the short rod 62, and nails 65 that are vertically arrayed on the lower end face of the plate 64. The nails 65 are attached to the filter media layer 4 and carry the filter media layer 4 out of the mounting hole 51. A hanging ring 12 is provided at the top of the side end of the filter tank 1, and a hook 66 that is hooked to the hanging ring 12 is provided at the top of the long rod 61. Hold the long rod 61 vertically so that each plate 64 is on top of each filter media layer 4. Then move the long rod 61 vertically downward so that the pins 65 on the plate 64 are directly driven into the filter media layer 4. Then move the long rod 61 upward so that the filter media layer 4 is removed from the mounting hole 51. Then move the long rod 61 horizontally to remove all the used filter media layers 4.

[0044] See Figure 4 Multiple sets of discharge rods 13 are welded and arranged evenly from top to bottom on the side of the filter tank 1. Each set of discharge rods 13 includes multiple rods arranged in parallel. The discharge rods 13 are inserted between the filter media layer 4 and the plate 64 to separate the filter media layer 4 and the plate 64. A sliding plate 14 is welded downward at an angle to the side of the filter tank 1 below each set of discharge rods 13 to receive the filter media layer 4 as it slides down. A waste box 15 for receiving the filter media layer 4 is horizontally arranged below the lowest discharge rod 13 on the side of the filter tank 1. The quick-change assembly 6 is moved to one side of the filter tank 1, and then the long rod 61 is moved until the discharge rod 13 is inserted between the filter media layer 4 and the plate 64. The long rod 61 is then moved upward so that the filter media layer 4 separates from the anchor 65 and falls onto the sliding plate 14, and finally slides down the sliding plate 14 into the waste box 15.

[0045] See Figure 1 A water distribution nozzle 21 is installed at the top of the filter tank 1. One end of the water distribution nozzle 21 is connected to the water inlet pipe 2, and the other end of the water distribution nozzle 21 has the same cross-sectional size as the filter media layer 4 in the horizontal direction. Water distribution holes 211 are evenly arrayed on the water distribution nozzle 21. This allows the water flowing in along the water inlet pipe 2 to enter the filter tank 1 more evenly after passing through the water distribution nozzle 21 and come into contact with the filter media layer 4, thereby improving the service life of the filter media layer 4.
