Development of Mobile Drip Irrigation Filters

Rate this post

Introduction: In recent years, some domestic manufacturers have independently designed and produced micro-irrigation filtration products based on imported and digested technologies. However, there are still some issues hindering their widespread adoption. This article addresses the development of mobile drip irrigation filters, aiming to overcome existing challenges and optimize filtration efficiency.

Main Components: The filter comprises several key components:

  1. Centrifugal Separator
  2. Sandstone Media Filter
  3. Mesh Filter
  4. Fertilization Device

Main Technical Parameters: After mass production and practical testing, the mobile drip irrigation filter has demonstrated promising technical parameters:

  1. Field Usage: Successfully used in the Nan Kou Farm in Alar with 15 units deployed.
  2. Efficiency: Capable of connecting drip irrigation for 0.87 hm² at once, with a filtration outlet connecting to a 10m soft hose and buried PE pipe length in the field of 90m.
  3. Engine Performance: Under medium and low-speed conditions, the test pressure at the nearest and farthest ends of the drip irrigation hose meets the requirements of drip irrigation.

Key Features:

  1. Enhanced Filtration Stability:
    • Introduction of a Partition Net: Enhances the stability of the sandstone filter by controlling different particle sizes within a certain space range, preventing filtration quality degradation over time.
  2. Improved Self-Cleaning Capability:
    • Blade Design at the Mesh Filter Outlet: Utilizes blades to change the water flow direction, enhancing the self-cleaning ability of the mesh filter and improving cleaning efficiency during backwashing.
  3. Mobility and Convenience:
    • Integration on a Mobile Chassis: The entire filter system is installed on a mobile chassis, allowing easy movement to different terrains and positions. This flexibility enables efficient irrigation across various fields without the need for multiple equipment setups.
  4. Stable Transportation:
    • Reduced Frame Height: Decreases the frame height for stable transportation, ensuring ease of manual operation for the engine.
  5. Temperature Regulation:
    • Supplementary Water Pipeline: Addresses rapid cooling water evaporation in high temperatures during summer, ensuring the engine’s normal operation.
  6. User-Friendly Design:
    • Horizontal Fertilization Tank: Simplifies manual fertilization by lowering the feeding port height, enhancing user convenience.

Conclusion: The development of mobile drip irrigation filters presents a promising solution to optimize filtration efficiency and overcome existing challenges. With enhanced stability, self-cleaning capabilities, and mobility, these filters offer a practical and user-friendly solution for efficient irrigation in various agricultural settings.
