Description

Technical Field

[0001] This utility model relates to a foldable and movable dust suppression fogging pile for mining operations. Background Technology

[0002] Currently, dust pollution is a widespread problem in mining areas, seriously affecting the health of workers and the safety of the working environment. Traditional dust suppression methods, such as fixed-point spraying or water trucks, suffer from problems such as fixed deployment, limited spray range, high energy consumption, and low efficiency. Especially in scenarios with complex terrain or frequently changing work faces, traditional methods struggle to balance flexibility and dust suppression effectiveness. Furthermore, due to the dynamic nature of dust concentration, existing systems lack responsive monitoring and adaptive control capabilities. Therefore, there is an urgent need for a new type of dust suppression device that is compact, mobile, highly automated, and offers excellent dust suppression efficiency to meet the needs of mining operations. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a foldable and mobile dust suppression fog pile for mining operations.

[0004] A foldable mobile dust suppression fogging system for mining operations includes a mobile chassis, a foldable tower body, and a spraying system. The mobile chassis includes four omnidirectional Mecanum wheels, each driven by an independent servo motor. Each of the four corners of the mobile chassis has a hydraulically adjustable support leg. A counterweight compartment is located below the mobile chassis, with a water injection compartment on the upper layer and a sand and gravel compartment on the lower layer. The spraying system includes a water injection compartment, a high-pressure plunger pump, a flexible water pipe, an electric winch, a distribution manifold, and a nozzle array. The foldable tower body includes a rotating base and a telescopic arm structure. The nozzle array is located at the end of the telescopic arm structure, and the flexible water pipe is arranged along the telescopic arm structure and its length is adjusted by the electric winch.

[0005] As a further improvement, each hydraulic leveling outrigger is equipped with a laser rangefinder and an independent hydraulic cylinder. The laser rangefinder can detect distances with high precision in real time, and the measurement data is transmitted in real time, providing accurate data for leveling operations. The independent hydraulic cylinder can independently complete its extension and retraction movements according to the control system's instructions, unaffected by the operating status of the other outriggers. This design allows the equipment to quickly achieve level calibration through the coordinated adjustment of the four outriggers when operating on uneven ground in mining areas, effectively avoiding the risks of spray deviation, equipment shaking, or even tipping over due to machine tilting, and significantly improving the equipment's operational stability in complex terrain.

[0006] As a further improvement, the bottom of the sand and gravel silo is equipped with an electric unloading gate. This electric unloading gate is directly controlled by the equipment control system and can be automatically opened and closed via remote commands or preset programs.

[0007] As a further improvement, a pre-filter is installed on the water injection tank, and a voltage-stabilizing accumulator is installed between the high-pressure plunger pump and the distribution manifold. The pre-filter adopts a multi-layer filtration structure, which can filter the water source injected into the water injection tank (such as surface water from the mining area or recycled wastewater), effectively intercepting silt, impurities, suspended solids, etc. in the water, preventing these impurities from entering the high-pressure plunger pump or nozzle and causing equipment wear and blockage, thus extending the service life of the pump body and nozzle.

[0008] As a further improvement, the retracted height of the telescopic arm structure is ≤1.5m, and the extended height is ≥6m. This solves the problem that traditional low-profile spray equipment cannot cover high-altitude dust, thus increasing the vertical coverage range of dust suppression operations.

[0009] As a further improvement, the nozzle array includes no fewer than eight fan-shaped nozzles. Compared to traditional spraying equipment with a small number of nozzles, this nozzle array has a larger coverage area and a more uniform droplet distribution, significantly improving dust suppression efficiency per unit time.

[0010] As a further improvement, an inhalable particulate matter sensor is included to monitor dust concentration. This avoids the waste of water and energy caused by the "blindly continuous spraying" of traditional spray equipment, achieving on-demand dust suppression, which not only ensures the dust suppression effect but also improves the energy efficiency and environmental friendliness of the equipment.

[0011] Further improvements include a battery compartment and solar panels for charging the batteries within. This power supply method reduces the equipment's reliance on cables or diesel generators, lowering energy costs and environmental pollution risks. The battery compartment also features power monitoring capabilities, providing early warnings of low power levels and ensuring continuous equipment operation.

[0017] Self-powered and monitored: Equipped with solar panels and a battery compartment for independent power supply, and also integrates an inhalable particulate matter sensor to achieve linkage between dust monitoring and spray control;

[0018] Double-layer counterweight design: The lower sand and gravel bin and the upper water injection bin work together to provide stable counterweight, while the sand and gravel bin has a discharge function, improving the versatility of operations;

[0019] Flexible deployment: The entire machine can be quickly moved, deployed and stored, making it especially suitable for dynamic working faces in mines and temporary dust suppression tasks. Attached Figure Description
