Description
Technical Field
[0001] This invention relates to the field of municipal water recycling, filtration and separation technology, specifically a municipal greening irrigation water recycling system. Background Technology
[0002] With the acceleration of urbanization, the demand for municipal greening irrigation water is increasing daily. Traditional irrigation systems mostly adopt a one-way water supply mode, resulting in low water resource utilization and a lack of effective filtration and recycling mechanisms. In existing technologies, irrigation systems often suffer from filter clogging due to fixed or inconvenient filter structures, making cleaning difficult and affecting the continuous operation of the system. Furthermore, in multi-filter parallel designs, replacing a single filter cartridge can cause system imbalance, requiring downtime for maintenance and reducing efficiency. Therefore, there is an urgent need for a municipal greening irrigation system that can achieve efficient filtration and separation, convenient maintenance, and support water recycling. Summary of the Invention
[0003] To address the above problems, this invention provides a municipal greening irrigation water recycling system.
[0004] The technical solution adopted by the present invention to solve its technical problem is: a municipal greening irrigation water circulation system, including a circulating water tank, wherein a filter part is rotatably arranged inside the circulating water tank, and an inlet pipe is arranged on the upper side of the filter part; The filtration section includes a connecting seat, a support seat, and two filter cylinders connected between the connecting seat and the support seat. The connecting seat is equipped with an inlet filter screen. The filter cylinders are detachably connected to the support seat. The support seat has an annular receiving groove. A connecting groove is formed at the upper part of the receiving groove. The connecting groove is used to receive the filter cylinders. A locking part is arranged inside the receiving groove. The locking part is used to limit the lower end of the filter cylinders.
[0005] As an optimization, the locking part includes an arc-shaped elastic rod and a limiting component connected to the middle of the elastic rod. A push block is disposed at the outer end of the elastic rod, and the push block extends into the bottom of the connecting groove. The limiting component includes a connecting rod and a connecting column. The connecting rod is connected between the connecting column and the elastic rod. An adjustment cavity is provided inside the connecting column. A support spring is disposed inside the adjustment cavity. Limiting wedges are slidably disposed at both ends of the adjustment cavity. The bottom of the filter cylinder is provided with a fixing ring, and the fixing ring has a limiting hole for accommodating a limiting wedge.
[0006] As an optimization, the two limiting wedges and the connecting column are arranged in an arc shape. The outer ends of the limiting wedges converge to form a guide tip. When the two filter cylinders are connected to the support base, the guide tip is located at the junction of the fixing ring and the connecting groove. When the filter cylinder moves upward, it can push the guide tip to move, so that the filter cylinder can be taken out of the connecting groove.
[0007] As an optimization, at least one filter cylinder is connected between the connecting seat and the support seat. After one of the filter cylinders is removed, the elastic rod releases its elastic potential energy, causing the push block to pop up. The limiting component tilts into the other filter cylinder, so that the guide tip completely enters the limiting hole, making the filter cylinder impossible to remove.
[0008] As an optimization, the connecting seat is annular, the inlet filter screen is disposed inside the connecting seat, and the bottom of the connecting seat is recessed to form a connecting groove, which is used to accommodate the upper end of the filter cylinder; A flat, round limiting wheel is provided in the middle of the connecting groove. The end diameter of the limiting wheel is smaller than the distance between the two filter cylinders, and the long diameter of the limiting wheel is larger than the distance between the two filter cylinders. The limiting wheel is provided with an operating handle.
[0009] As an optimization, the water inlet pipe includes a connecting section and a water inlet section, one end of the water inlet section is rotatably connected to the connecting section, and the other end of the water inlet section is bent toward the inside of the connecting seat.
[0010] As an optimization, a drive motor is provided on the inner bottom of the circulating water tank, and the output shaft of the drive motor is connected to the support base.
[0011] As an optimization, the filtration section is coaxially arranged with the circulating water tank, and a drain pipe is provided at the top of the circulating water tank.
[0012] The beneficial effects of this plan are as follows: Through the design of a rotatable filter section (including dual filter cartridges) and a circulating water tank, dynamic filtration, separation, and recycling of irrigation water are achieved, significantly improving water resource utilization and reducing waste. The filter cartridge and support base are detachably connected. With the locking part of the elastic rod and the limiting wedge, the guide tip can be triggered to disengage from the limiting hole when a single filter cartridge moves upward, realizing quick disassembly. When one of the filter cartridges is removed, the elastic rod automatically releases potential energy, the push block pops out and tilts the limiting component to lock the other filter cartridge, so that at least one filter cartridge is kept in the filtration system, preventing the system from becoming unbalanced due to misoperation and ensuring safety during maintenance.

In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0022] like Figures 1-6 As shown, a municipal greening irrigation water recycling system includes a circulating water tank 1, a filter section is rotatably arranged inside the circulating water tank 1, and an inlet pipe is arranged on the upper side of the filter section. The filtration section includes a connecting seat 2, a support seat 3, and two filter cylinders 4 connected between the connecting seat 2 and the support seat 3. The connecting seat 2 is equipped with an inlet filter screen. The filter cylinders 4 are detachably connected to the support seat 3. The support seat 3 has an annular receiving groove 5. The upper part of the receiving groove 5 has a connecting groove 6 for receiving the filter cylinders 4. The receiving groove 5 has a locking part inside, which is used to limit the lower end of the filter cylinders 4.
[0023] Both filter cartridges 4 can be removed simultaneously. When one filter cartridge 4 is removed, the locking part locks the other filter cartridge 4, making it impossible to remove that filter cartridge 4.
[0024] The circulating water tank 1 is made of corrosion-resistant materials (such as stainless steel or engineering plastics) and has a drain port at the bottom for easy periodic cleaning of sediment. A baffle plate can be added to the inner wall of the tank to ensure even distribution of filtered water and prevent localized sludge buildup. The filtration section is driven by a motor 17, with an adjustable speed (30-60 rpm recommended), ensuring the inlet filter screen self-cleans in dynamic water flow while preventing clogging of the filter cartridge 4 by impurities.
[0025] The locking part includes an arc-shaped elastic rod 7 and a limiting component connected to the middle of the elastic rod 7. A push block is disposed at the outer end of the elastic rod 7, and the push block extends into the bottom of the connecting groove 6. The limiting component includes a connecting rod 8 and a connecting post 9. The connecting rod 8 is connected between the connecting post 9 and the elastic rod 7. An adjustment cavity is provided inside the connecting post 9. A support spring 10 is disposed inside the adjustment cavity. Limiting wedges 11 are slidably disposed at both ends of the adjustment cavity. The bottom of the filter cylinder 4 is provided with a fixing ring 12, and the fixing ring 12 has a limiting hole for accommodating the limiting wedge 11.
[0026] When both filter cylinders 4 are inside the connecting groove 6, the elastic rod 7 is in a compressed state and tends to extend outward. When one of the filter cylinders 4 is disassembled, one end of the elastic rod 7 will release elastic potential energy, and the whole device will deflect towards the empty connecting groove 6, so that the limiting wedge 11 goes deeper into the connected filter cylinder 4.
[0027] The spring stiffness is calculated to ensure that the limiting wedge 11 is only partially embedded in the limiting hole when the filter cartridge 4 is installed normally, and can be quickly and deeply locked during single-cartridge maintenance.
[0028] The elastic rod 7 is made of a high-elasticity alloy material, which can store sufficient elastic potential energy in the pre-compressed state. When one side of the filter cylinder 4 is removed, the push block of the elastic rod 7 quickly rises, pushing the limiting component to tilt towards the other filter cylinder 4, so that the limiting wedge 11 is completely locked into the limiting hole, forming a mechanical interlock.
[0029] The two limiting wedges 11 and the connecting post 9 are arranged in an arc shape. The outer ends of the limiting wedges 11 converge to form a guide tip. When the two filter cylinders 4 are connected to the support base 3, the guide tip is located at the junction of the fixing ring 12 and the connecting groove 6. When the filter cylinder 4 moves upward, it can push the guide tip to move, so that the filter cylinder 4 can be taken out from the connecting groove 6.
[0030] The guide tip of the limiting wedge 11 is designed as a bevel. When it engages with the limiting hole of the fixing ring 12, it needs to overcome the resistance of the support spring 10 to disengage, thus ensuring locking stability.
[0031] When the locking part is set horizontally, pull one of the filter cylinders 4 upwards. The filter cylinder 4 squeezes the limiting wedge block 11. Under the action of the guide tip, the limiting wedge block 11 is squeezed outwards, thereby unlocking the filter cylinder 4.
[0032] At least one filter cylinder 4 is connected between the connecting seat 2 and the support seat 3. After one of the filter cylinders 4 is removed, the elastic rod 7 releases its elastic potential energy, causing the push block to pop up. The limiting component tilts into the other filter cylinder 4, so that the guide tip completely enters the limiting hole, making the filter cylinder 4 impossible to remove.
[0033] The connecting seat 2 is annular, the inlet filter screen is disposed inside the connecting seat 2, and the bottom of the connecting seat 2 is recessed to form a connecting groove, which is used to accommodate the upper end of the filter cylinder 4; A flat, round limiting wheel 13 is disposed in the middle of the connecting groove. The short diameter of the limiting wheel 13 is smaller than the distance between the two filter cylinders 4, and the long diameter of the limiting wheel 13 is larger than the distance between the two filter cylinders 4. The limiting wheel 13 is provided with an operating handle 14.
[0034] It uses multi-layer stainless steel mesh (mesh count optional 80-120 mesh) that rotates synchronously with the rotating connecting seat 2 to prevent impurities from adhering.
[0035] The operating handle 14 can be rotated manually. The flat, round design of the limiting wheel 13 allows for two states: when the two sides of the end diameter are in contact with the filter cylinder 4, the connecting seat 2 and the filter cylinder 4 are detachable; when the two sides of the long diameter are in contact with the filter barrel, the two filter cylinders 4 are squeezed together, locking the positions of the filter cylinder 4 and the connecting seat 2.
[0036] The water inlet pipe includes a connecting section 15 and a water inlet section 16. One end of the water inlet section 16 is rotatably connected to the connecting section 15, and the other end of the water inlet section 16 is bent toward the inside of the connecting seat 2.
[0037] Rotating the inlet section 16 allows it to switch between adjacent circulating water tanks 1. The inlet section 16 and the connecting section 15 can rotate freely 360° via bearings. The bent end of the inlet section 16 is equipped with a nozzle, which can adjust the water outlet angle to prevent water from directly hitting the filter screen and causing local wear.
[0038] A drive motor 17 is installed on the inner bottom of the circulating water tank 1, and the output shaft of the drive motor 17 is connected to the support base 3.
[0039] The drive motor 17 is a waterproof geared motor, and its output shaft is rigidly connected to the support base 3 via a coupling to ensure that there is no eccentric vibration when the filter section rotates. A shock-absorbing pad can be installed at the bottom of the circulating water tank 1 to further reduce noise.
[0040] The filter section is coaxially arranged with the circulating water tank 1, and a drain pipe is provided on the upper part of the circulating water tank 1.
[0041] How to use: Initial installation: Fix the circulating water tank 1 near the irrigation area and connect the external water source to the inlet pipe; Install two filter cartridges 4: insert their upper ends into the connecting groove of the connecting seat 2 and press their lower ends into the connecting groove 6 of the support seat 3 until the guide tip of the limiting wedge 11 is engaged in the limiting hole of the fixing ring 12.
[0042] Start the system: Turn on drive motor 17, set the speed (40 rpm recommended), and start the water pump to inject water into the inlet pipe.
[0043] After initial filtration through the inlet filter screen, the water enters the filter cylinder 4, where impurities are trapped. The clean water flows into the circulating water tank 1 and then back to the irrigation network through the drain pipe.
[0044] Maintenance operation: Single cylinder maintenance: Lift any filter cylinder 4 upwards, the limit wedge 11 is squeezed out of the limit hole, the elastic rod 7 releases potential energy to lock the other filter cylinder, ensuring the continuous operation of the system.
[0045] Dual-cylinder cleaning: Rotate the limiting wheel 13 to the short diameter position to separate the connecting seat 2 from the filter cylinder 4, and at the same time remove both filter cylinders 4 for rinsing.
