A pump-mounted mesh filter drive device

Abstract

This utility model provides a pre-pump mesh filter drive device, including a hydraulic drive box, a water turbine structure, a planetary reducer, a small pulley, a reducing joint, a frame, a synchronous belt, and a large pulley. The hydraulic drive box is mounted on the frame, and the water turbine structure is fixedly connected to the drive shaft. The drive shaft extends out of the hydraulic drive box and is connected to the small pulley via the planetary reducer. The large pulley is fixedly connected to the drive shaft of the filter cartridge, and the small pulley and the large pulley are driven by a synchronous belt. The reducing joint is located on and passes through the side wall of the hydraulic drive box, with the water outlet direction of the reducing joint facing the blades of the water turbine structure. By replacing the motor drive with a water turbine drive, the water turbine is rotated by hydraulic power, and the torque is amplified by the planetary reducer, thereby increasing the output torque of the water turbine. This reduces the complexity of the structure, eliminates safety risks of the equipment, and reduces maintenance costs during long-term use.

Description

Technical Field

[0001] This utility model belongs to the field of agricultural equipment technology, specifically relating to a pump pre-pump mesh filter drive device. Background Technology

[0002] Pre-pump mesh filters play a crucial role in irrigation systems, primarily intercepting solid impurities in the water source, including silt, weed fragments, fine particles, and insects. Without effective filtration, these impurities accelerate equipment wear, affecting the normal operation of the pump and subsequent water delivery equipment. Unfiltered impurities can cause wear on pump impellers and seals, even leading to premature damage. Furthermore, impurities can clog sprinklers and drippers, affecting the even distribution of water flow and thus reducing the efficiency and stability of the entire irrigation system.

[0003] To maintain filtration effectiveness and facilitate maintenance, modern filters are often equipped with backwashing structures and rotating filter screens. This rotating filter screen backwashing structure offers several advantages. It effectively prevents impurities from accumulating and clogging the filter screen, improving the continuity and efficiency of filtration. Simultaneously, automatic cleaning reduces maintenance burden, extends filter screen lifespan, and minimizes damage from hard impurities, thus ensuring long-term stable filtration performance. Currently, this structure typically uses an electrically driven shaft to slowly rotate the filter screen, moving the screen with attached impurities to the backwashing structure for flushing. However, this motor-driven filter screen rotation method suffers from structural complexity, numerous potential failure points, low reliability in humid environments, the risk of electrical leakage, and high maintenance costs. Utility Model Content

[0004] To address the existing difficulties and shortcomings, this utility model proposes a pre-pump mesh filter drive device, which aims to reduce structural complexity, eliminate equipment safety risks, and reduce maintenance costs during long-term use.

The hydraulic drive box is mounted on the frame, and the water turbine structure is fixedly connected to the drive shaft. The drive shaft extends out of the hydraulic drive box and is connected to the small pulley via the planetary reducer. The large pulley is fixedly connected to the drive shaft of the filter cartridge, and the small pulley and the large pulley are driven by a synchronous belt. The reducing joint is disposed on and penetrates the side wall of the hydraulic drive box, and the water outlet direction of the reducing joint faces the blades of the water turbine structure.

[0006] Furthermore, the water turbine structure includes an impeller, an impeller disk, and a locking device.

[0007] The impeller disk has annularly distributed impeller mounting holes on its outer side, a shaft hole at its center, and a locking device mounting hole next to the shaft hole; the impeller has a through hole and is mounted on the impeller disk by clamping and bolts; the locking device is installed on one side of the impeller disk and is used to fix the impeller disk to the drive shaft.

[0008] Furthermore, the housing of the planetary reducer is mounted on a frame; the frame is mounted on a pre-pump mesh filter.

[0009] Furthermore, the drive shaft is equipped with bearings and sleeves. The drive shaft is connected to the hydraulic drive box through the bearings, and the sleeves are set on both sides of the water turbine structure for positioning the impeller disk.

[0010] Furthermore, a rectangular water outlet is provided below the hydraulic drive box.

[0011] Furthermore, the impeller has a left-right symmetrical structure, and the side facing the outlet of the reducing connector has a spoon-shaped groove.

[0012] Furthermore, the locking device has a shaft hole in the middle that is slightly larger than the diameter of the drive shaft for the drive shaft to pass through; two through holes are provided next to the shaft hole of the locking device for fixing the impeller disk and the locking device together with bolts; a groove is cut at the center of the circular surface of the locking device, and a threaded hole is provided on the cylindrical surface, so as to use screws to clamp the drive shaft with the locking device, thereby fixing the impeller disk and the drive shaft together.

This setup replaces the traditional motor drive method. This solution eliminates the potential safety hazard of electric leakage, effectively simplifies the device structure, and reduces the maintenance costs of the system during long-term operation.
