Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural water-saving irrigation technology, and in particular to a mesh bag filter device suitable for drip irrigation. Background Technology
[0002] Because current drip irrigation systems commonly use single-wing labyrinth drip tape, they have very high requirements for the impurity content of irrigation water. Therefore, a filtration system needs to be installed at the head of the drip irrigation system, so that canal water or well water is filtered before being fed into the drip irrigation network. Currently, head-of-line filtration methods include centrifugal filters, mesh filters, sand filters, disc filters, and combined filtration stations. These can treat impurities such as silt and organic matter in the water source and are essential supporting equipment for modern water-saving irrigation systems. These filtration devices need to meet requirements for water quality, flow rate, and pressure, and should also have backwashing capabilities. Currently used filter equipment is relatively expensive, and the backwashing effect is not ideal, causing the filter cartridges to lose function prematurely and resulting in a short service life; typically, the filter equipment needs to be replaced every 2-3 years.
[0003] Based on the above-mentioned technical problems, this utility model provides a mesh bag filter device suitable for drip irrigation. Utility Model Content
[0004] The purpose of this invention is to provide a mesh bag filter device suitable for drip irrigation to solve the problems existing in the prior art.
[0005] To achieve the above objectives, this utility model provides the following solution: This utility model provides a mesh bag filter device suitable for drip irrigation, comprising:

[0021] The components include: 1. male connector; 2. pipe; 3. female connector; 4. slot; 5. positioning ball; 6. mounting ring; 7. filter screen; 8. clamp; 9. bolt; 10. sliding sleeve; and 11. spring. Detailed Implementation
[0022] 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.
[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0024] Reference Figure 1 This utility model provides a mesh bag filter device suitable for drip irrigation, comprising:
[0025] The connector 1 has two sets of connector 1, which are arranged symmetrically. The end of the connector 1 is fitted with a pipe 2, and the pipe 2 is fixed to the connector 1 by a fixing component.
[0026] The female connector 3 is positioned between two sets of male connectors 1, and the male connectors 1 are inserted into the female connector 3. The outer wall of the male connector 1 is provided with a slot 4, and the outer wall of the female connector 3 is provided with an installation slot. A positioning ball 5 is movably installed in the installation slot and is engaged in the slot 4. A locking component is sleeved on the outer wall of the female connector 3, and the locking component is in a limiting cooperation with the positioning ball 5.
[0027] The filter assembly includes a mounting ring 6 and a filter screen 7. The filter screen 7 has a conical structure and is fixed to one side of the mounting ring 6. The mounting ring 6 is detachably connected to the end of the connector 1 located behind the water inlet. The filter screen 7 is located inside the connector 1. A sealing component is installed at the end of the other connector 1, and the sealing component abuts against the mounting ring 6.
[0028] In operation, this invention first arranges two sets of connector heads 1 symmetrically, then fits the pipe 2 onto the end of the connector head 1 and secures it to the connector head 1 using a fixing component, ensuring a firm and sealed connection. Next, the connector head 1 is inserted into the female connector head 3. During insertion, the positioning ball 5 in the mounting groove on the outer wall of the female connector head 3 moves due to pressure from the outer wall of the connector head 1. When the connector head 1 is inserted into the appropriate position, the positioning ball 5 engages in the slot 4 on the outer wall of the connector head 1, achieving initial positioning of the connector head 1 and the female connector head 3. Then, a locking component is fitted onto the outer wall of the female connector head 3. The locking component and the positioning ball 5 engage in a limiting fit, preventing the positioning ball 5 from dislodging from the slot 4, thus ensuring a stable connection between the connector head 1 and the female connector head 3. Finally, a mounting ring 6 with a conical filter screen 7 is detachably connected to the end of the connector head 1 located behind the water inlet, so that the filter screen 7 is located inside the connector head 1. A sealing component is installed at the end of the other connector 1, and it abuts against the mounting ring 6 to ensure the airtightness of the entire device and prevent water leakage. Water flows from pipe 2 through connector 1 into the device, first passing through filter screen 7. Because filter screen 7 has a conical structure, it increases the filtration area, intercepting impurities in the water flow. The filtered water continues to flow through pipe 2 to the drip irrigation system. When filter screen 7 accumulates impurities and needs cleaning, the sealing component is disassembled, the mounting ring 6 is removed from connector 1, and filter screen 7 is taken out for cleaning or replacement. After cleaning or replacement, the mounting ring 6 is reinstalled onto connector 1, and the sealing component is installed to restore the device to normal operation.
[0029] The solution is further optimized. The fixing component includes clamp 8, which is fitted onto the outer wall of pipe 2. Both ends of clamp 8 are locked by bolts 9.
[0030] After fitting pipe 2 onto the end of connector 1, clamp 8 is fitted onto the outer wall of pipe 2, tightly wrapping the connection between pipe 2 and connector 1. Then, bolts 9 are used to lock both ends of clamp 8. As bolts 9 are tightened, clamp 8 applies uniform pressure to pipe 2, ensuring a tight fit between pipe 2 and connector 1, thereby enhancing the connection strength and sealing, and preventing water leakage from the connection.
[0031] When it is necessary to disassemble pipe 2, simply loosen bolt 9 and remove clamp 8 from pipe 2 to easily separate pipe 2 from connector 1. The operation is simple and convenient.
[0032] The locking assembly further optimizes the design by including two symmetrically sliding sleeves 10 connected to the outer wall of the mating head 3. A spring 11 is fixed in the middle of the outer wall of the mating head 3. The two sets of sliding sleeves 10 are fixed to the two ends of the spring 11 respectively. An annular groove is provided on the inner wall of the sliding sleeve 10. The cross-sectional shape of the annular groove is a right trapezoid. The inclined surface of the annular groove abuts against the positioning ball 5.
[0033] When the male connector 1 is inserted into the female connector 3, the outer wall of the male connector 1 presses against the positioning ball 5, causing the positioning ball 5 to move outward. At this time, the sliding sleeve 10 is in its initial position under the action of the spring 11, and the inclined surface of the annular groove on the inner wall of the sliding sleeve 10 abuts against the positioning ball 5. As the male connector 1 continues to be inserted, the positioning ball 5 rolls along the inclined surface of the annular groove, simultaneously pushing the sliding sleeve 10 to slide to both sides, stretching the spring 11.
[0034] When the docking head 1 is inserted into the appropriate position, the positioning ball 5 is inserted into the groove 4 on the outer wall of the docking head 1. At this time, the elastic force of the spring 11 causes the sliding sleeve 10 to slide back to the center. The right-angled edge of the annular groove on the inner wall of the sliding sleeve 10 plays a limiting role on the positioning ball 5, preventing the positioning ball 5 from coming out of the groove 4, thereby ensuring a stable connection between the docking head 1 and the docking female head 3.
[0035] When it is necessary to disassemble the mating head 1, slide the sliding sleeve 10 to both sides, so that the inclined surface of the annular groove on the inner wall of the sliding sleeve 10 contacts the positioning ball 5 again, and the spring 11 is further stretched. At this time, the positioning ball 5 loses the limiting effect of the sliding sleeve 10 and can be dislodged from the slot 4, and the mating head 1 can be pulled out from the mating head 3.
[0036] The design is further optimized so that the sealing assembly includes a sealing ring, which is fixed to the end of one of the sets of mating heads 1.
[0037] The design was further optimized so that the length of pipe 2 is 1m-1.5m.
[0038] The design has been further optimized, and filter screen 7 is made of 120-mesh fabric.
[0039] When water flows through filter screen 7, impurities larger than the mesh size are trapped on the surface of filter screen 7, while water smaller than the mesh size can continue to flow through filter screen 7. This filtration method effectively removes impurities such as silt and suspended solids from the water flow, ensuring that the water entering the drip irrigation system is clean, preventing clogging of the drip irrigation equipment, and improving the operating efficiency and service life of the drip irrigation system.
