Description

[0001] manual Technical Field

[0002] This invention belongs to the field of in-situ hydrogen production module installation and protection mechanical structure for mobile equipment, and is applicable to methanol-to-hydrogen modules for unmanned mining loaders and tiltrotor aircraft. Background Technology

[0003] The dust concentration in the mine is extremely high, and the high-altitude airflow of the aircraft carries fine dust, which quickly clogs ordinary single-stage filters. Dust adheres to the catalyst, reducing hydrogen production efficiency. The continuous alternating vibration of the mine road surface and the aircraft causes the internal catalyst carrier to break and the pipeline welds to fatigue and leak when the hydrogen production module is rigidly installed. The existing mounting brackets only provide single vertical vibration damping and lack a multi-stage air intake dust prevention and integrated structure for pipeline deformation compensation. The dual damage from dust and vibration significantly shortens the service life of the in-situ hydrogen production module, and the maintenance frequency is extremely high in unattended scenarios. Summary of the Invention

[0004] Purpose of the invention It simultaneously solves three major problems of dust blockage, multi-directional vibration damage, and pipeline thermal expansion vibration stress in mobile hydrogen production modules. It integrates vibration reduction, four-level dust prevention, automatic dust removal, and pipeline compensation into a single mounting bracket, making it suitable for harsh mining and airborne operating conditions. Technical solution

[0005] The hydrogen production module is fixed to the module support base, and the multi-dimensional composite shock absorption assembly under the base realizes three-dimensional vibration absorption; the four-stage filtration unit at the air inlet intercepts dust in stages, and automatically pulses backflushing to clean the dust when the pressure difference exceeds the limit; the travel limit blocks around the base prevent large impacts and hard collisions; all inlet and outlet pipelines of the module are equipped with flexible compensation joints to release pipeline stress caused by vibration and thermal expansion and contraction. Beneficial effects

[0006] 1. Four-stage progressive filtration + automatic backflushing significantly reduces dust entering the reforming chamber and protects the catalyst; 2. Three-dimensional composite shock absorption + stroke limiter to prevent the carrier from breaking or the shell from impact caused by bumps and vibrations; 3. Flexible pipe joints offset deformation stress and prevent leakage at pipe welds; 4. The integrated structure makes the whole machine easy to assemble and can be directly matched with the external dimensions of various in-situ hydrogen production modules. Attached Figure Description

Detailed Implementation

[0008] The module's support base is welded from thickened steel plates, and the in-situ hydrogen production module is secured with bolts. Multiple sets of multi-dimensional composite shock-absorbing assemblies are evenly arranged at the bottom of the base, with alternating layers of thin metal plates and weather-resistant damping rubber to achieve vertical, front-to-back, and left-to-right vibration reduction. Travel limit blocks are welded to all four sides of the base, with a 4mm buffer gap between the base and the sides. The hydrogen production module's air inlet flange connects to a four-stage air intake filtration integrated unit, which internally includes a coarse metal filter, a cyclone separation chamber, a composite pleated filter, and an electrostatic micro-dust removal module. An automatic pulse backflushing branch line connects to the vehicle's air tank, with nozzles aimed at the dust accumulation surfaces of each filter layer. A differential pressure sensor detects the degree of blockage, and pulse purging is initiated when the equipment is idling. Flexible compensation joints are installed on both the methanol inlet and hydrogen outlet pipelines of the module to absorb vibration displacement and temperature deformation. The entire mechanism has pre-drilled standard mounting holes, allowing direct installation in the loader's power compartment or the wingtip power compartment of an aircraft, for use with the core in-situ hydrogen production module.
