[0018] 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. Example

[0019] like Figures 1-3 As shown, the multi-filtration intelligent water and fertilizer integration hub includes a fertilizer tank 1, a fertilizer pump 2, a mesh filter 3, a centrifugal filter, and a base plate 20. The base plate 20 is used to support the water and fertilizer integration hub. The base plate 20 can be a fixed mounting base, a movable mounting base, or a vehicle frame structure.

[0020] Centrifugal filtration unit 4 is used to centrifuge the water flowing into the integrated water and fertilizer system. The centrifugal filtration unit 4 has an inlet pipe for connecting to the water source equipment. An inlet control valve 5 is installed on the inlet pipe. The inlet control valve 5 can be a manually operated ball valve or an electromagnetically controlled valve. The inlet control valve 5 allows for the adjustment of the inlet pipe's on / off state. A pressure gauge is installed on the inlet pipe at the inlet position of the centrifugal filtration unit 4. A pressure-holding valve is installed between the pressure gauge and the inlet control valve 5 to automatically regulate the water pressure in the inlet pipe.

[0021] A water inlet pipe 17 is installed between the water inlet valve and the pressure-holding valve on the water inlet pipe. The water inlet pipe 17 is connected to the water inlet pipe and is equipped with a water inlet control valve. The water inlet control valve can be a manual valve or a solenoid valve to regulate the on / off state of the water inlet pipe 17. When the water inlet control valve is open, the water entering the water inlet pipe can be discharged from the water inlet pipe 17, making it convenient to lead out to the water and fertilizer integration system for use. When the water inlet control valve is closed, the water entering the water inlet pipe enters the water and fertilizer integration system for use.

[0022] The centrifugal filtration unit 4 includes at least two centrifugal filters, which are connected in series. (See also...) Figure 2 Preferably, there are two centrifugal filters: a first centrifugal filter and a second centrifugal filter. The inlet of the first centrifugal filter is the same as the inlet of the centrifugal filtration mechanism 4, and the outlet of the second centrifugal filter is the same as the outlet of the centrifugal filtration mechanism. The outlet of the first centrifugal filter is connected to the inlet of the second centrifugal filter via an intermediate pipe. Water from the water source equipment first enters the first centrifugal filter for centrifugal filtration, and the filtered clean water is then filtered again in the second centrifugal filter before flowing out from the outlet of the second centrifugal filter.

[0023] The centrifugal filtration mechanism 4 has a water supply pipe 6 at its outlet. Both the intermediate pipe and the water supply pipe 6 are equipped with vent valves to meet the usage requirements of the centrifugal filter. The water supply pipe 6 connects to the inlet of the mesh filter 3, delivering the water treated by the centrifugal filtration mechanism 4 to the mesh filter 3 for further filtration. Both the centrifugal filter and the mesh filter 3 utilize readily available and mature technologies; their structures will not be described in detail here. The mesh filter 3 has an outlet pipe 7 at its outlet, and an outlet control valve is installed on the outlet pipe 7. The outlet control valve can be either a manual valve or a solenoid valve, allowing adjustment of the on / off state of the outlet pipe 7. The outlet pipe 7 is used to draw out the water filtered by the mesh filter 3.

[0024] In some embodiments, the drain sections of the mesh filter 3 and each centrifugal filter are connected to the same drain pipe 14. The drain pipe 14 is equipped with a connecting flange for connecting to the pipe network required for draining. The drain pipe 14 is also equipped with a branch drain pipe, which can serve as a spare pipe for the drain pipe 14 and also facilitates personnel to drain the filters without affecting the pipe network connected to the drain pipe 14. The branch drain pipe is equipped with a drain control valve.

[0025] In other embodiments, each centrifugal filter shares a settling tank, and the drain outlet of the mesh filter 3 is also connected to the settling tank to facilitate the discharge of silt and other sediment from the filter.

[0026] The water supply pipe 6 is connected to a fertilizer inlet pipe 9 and a fertilizer return pipe 8. The fertilizer return pipe 8 is connected to the water supply pipe 6 and the outlet of the fertilizer pump 2. The connection between the water supply pipe 6 and the fertilizer return pipe 8 is downstream of the water supply pipe 6. The fertilizer inlet pipe 9 is connected to the water supply pipe 6 and the inlet of the fertilizer pump 2. The connection between the water supply pipe 6 and the fertilizer inlet pipe 9 is upstream of the water supply pipe 6. The fertilizer inlet pipe 9 is also connected to a water supply pipe 10 and a fertilizer outlet pipe 12. The water supply pipe 10 is connected to the fertilizer inlet pipe 9 and the water inlet of the fertilizer tank. A water supply control valve 11 is installed on the water supply pipe 10, which can adjust the on / off state of the water supply pipe 10. The connection between the fertilizer inlet pipe 9 and the water supply pipe 10 is upstream of the fertilizer inlet pipe 9. The fertilizer outlet pipe 12 is connected to the fertilizer outlet of the fertilizer inlet pipe 9 and the fertilizer outlet of the fertilizer tank. A fertilizer outlet control valve 13 is installed on the fertilizer outlet pipe 12, which can adjust the on / off state of the fertilizer outlet pipe 12. The connection between the fertilizer inlet pipe 9 and the fertilizer outlet pipe 12 is downstream of the fertilizer inlet pipe 9.

[0027] The fertilizer tank is mounted on the base plate 20 and is used to hold liquid fertilizer. When the water supply control valve 11 is closed and the fertilizer outlet control valve 13 is open, the fertilizer pump 2 can draw water from the water supply pipe 6 through the fertilizer inlet pipe 9, and simultaneously draw liquid fertilizer from the fertilizer tank using both the fertilizer inlet pipe 9 and the fertilizer outlet pipe 12. Then, the water mixed with liquid fertilizer is returned to the water supply pipe 6 through the fertilizer return pipe 8. The water containing liquid fertilizer in the water supply pipe 6 is filtered by the mesh filter 3 and then discharged from the outlet pipe 7 for use. When the water supply control valve 11 is open, water in the water supply pipe 6 can enter the fertilizer tank through the water supply pipe 10 for replenishment.

[0028] A fastening plate 15 is also provided on the base plate 20. A screw is provided on the fastening plate 15. After the fertilizer tank 1 is placed on the base plate 20, the fastening plate 15 is placed on the fertilizer tank 1 and connected to the base plate 20 by the screw to fix the fertilizer tank 1 to the base plate 20. A stirring motor 16 is installed on the fastening plate 15. The rotating part of the stirring motor 16 is connected to the stirring shaft. The stirring shaft is located inside the fertilizer tank 1 and is provided with a stirring paddle. The stirring motor 16 drives the stirring shaft to rotate, and the stirring paddle can be used to stir the fertilizer tank 1, which facilitates the mixing of water and fertilizer.

[0029] As an optional implementation, the multi-filtration intelligent water and fertilizer integrated hub of this embodiment also includes a control mechanism 18. The control mechanism 18 adopts a controller in the form of a single-chip microcomputer or other existing technology. When the water supply control valve 11 and the fertilizer discharge control valve 13 are solenoid valves, the control mechanism 18 is connected to the mesh filter 3, the stirring motor 16, the water supply control valve 11, the fertilizer discharge control valve 13, and the fertilizer pump 2. The control mechanism 18 can realize the control of each component. The fertilizer discharge control valve 13 is preferably a diaphragm valve.

[0030] In some embodiments, a compartment 19 is also provided on the base plate 20.
