Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen storage alloy crushing, and in particular to a device and method for crushing hydrogen storage alloys in a combined manner using multiple methods. Background Art

[0002] Hydrogen storage alloys are a type of alloy material that can reversibly absorb and release large amounts of hydrogen. Under certain conditions, they can react chemically with hydrogen, decomposing hydrogen molecules into hydrogen atoms, which then enter the lattice gaps of the alloy to form metal hydrides, thereby achieving hydrogen storage.

[0003] Nowadays, in order to improve the reaction efficiency of hydrogen storage alloys and increase the contact area between hydrogen storage alloys and hydrogen, the hydrogen storage alloys need to be crushed. However, the existing technology generally uses jaw crushers, ball mills or air flow mills to crush the hydrogen storage alloys one by one. During the crushing process, during the crushing process and the transfer process, not only can the hydrogen storage alloys fail to be completely sealed from the external gas, increasing the contact time between the hydrogen storage alloys and the gas, but the step-by-step crushing efficiency is also low.

[0004] During the crushing process of hydrogen storage alloys, many metal elements in the alloys have relatively active chemical properties. They are not only easy to undergo oxidation reactions with oxygen in the air, changing the composition of the alloy and reducing the hydrogen storage performance, but also some crushing equipment will generate heat during the crushing process due to the conversion of mechanical energy, such as the collision and friction between balls and alloy particles, balls and balls, and particles and container walls during ball milling. For hydrogen storage alloys, excessively high temperatures may cause phase changes in the alloys or decomposition of hydrides, thereby reducing the performance of the hydrogen storage alloys after crushing.

[0041] Secondary crushing, after the primary crushing of the hydrogen storage alloy, the storage valve 5 is opened to allow the alloy in the storage tube 4 to fall into the secondary crushing box 6, and then the power motor 15 is started, and the output end of the power motor 15 drives the bevel gear 16 to rotate, the rotation of the bevel gear 16 drives the bevel gear 2 17 to rotate, the rotation of the bevel gear 2 17 drives the limit tube 2 13 to rotate, and the rotation of the limit tube 2 13 drives the power rod 9 to rotate, and the rotation of the power rod 9 drives the conical crushing head 10 to rotate, and the eccentric rotation of the conical crushing head 10 makes the eccentric crushing head hit the alloy passing through the secondary crushing cavity, and the large particles of the alloy are secondary crushed under the eccentric movement of the conical crushing head 10.

[0042] Three-stage crushing. After the hydrogen storage alloy is crushed twice, the alloy will fall through the secondary crushing cavity to the three-stage annular crushing plate 22 in the crushing ring hole, and then under the rotation of the power rod 9, the power rod 9 will also drive the limit tube three 21 to rotate, and the rotation of the limit tube three 21 will drive the crushing shaft 23 and the material-discharging rod 25 to move. Under the movement of the crushing shaft 23, the crushing shaft 23 drives the crushing roller 24 to move. Under the movement of the crushing roller 24, the alloy on the three-stage annular crushing plate 22 is crushed three times. Under the rotation of the material-discharging rod 25, the spring telescopic rod 26 will drive the conical material-discharging block 27 to move. Under the movement of the conical material-discharging block 27, the crushed alloy on the three-stage annular crushing plate 22 will fall through the filter material through hole to the bottom of the three-stage annular crushing plate 22. The movement of the conical material-discharging block 27 can also effectively prevent the filter material through hole from being blocked.

[0043] Centralized material storage. After the hydrogen storage alloy is subjected to three-stage crushing, the alloy after the three-stage crushing will fall into the corresponding feeding cavity through the filter material through hole under the guidance of the conical guide plate 28, so that the alloy falls onto the corresponding feeding belt 32, and then the feeding motor 34 is started. The output end of the feeding motor 34 drives the feeding rod 33 connected thereto to rotate, and the rotation of the feeding rod 33 drives the feeding roller 31 connected thereto to rotate, and the rotation of the feeding roller 31 drives the feeding belt 32 to transmit. Under the transmission of the feeding belt 32, the hydrogen storage alloy on the feeding belt 32 is concentrated and accumulated in the storage box 30. The storage boxes 30 on both sides of the crushing box 3 are alternately disassembled to achieve the storage of the hydrogen storage alloy.

[0044] Crushing and cooling, when the hydrogen storage alloy is crushed, the air supply fan 40 is started. Under the agitation of the air supply fan 40, the gas in the crushing box 3 circulates along the secondary crushing box 6, the air inlet pipe 35, the dust removal box 37, the air supply box 39 and the air supply pipe 36. During the gas flow, the dust generated in the crushing process will be filtered through the multi-stage dust filter group 38 as the gas flows, and the flowing gas will reduce the temperature of the gas when passing through the condensation and cooling plate 41, thereby cooling the hydrogen storage alloy in the crushing process.

[0045] Crushing adjustment: When the hydrogen storage alloy is subjected to secondary and tertiary crushing, the positioning electric cylinder 19 is started, and the output end of the positioning electric cylinder 19 drives the power rod 9 to move, and the output end of the positioning electric cylinder 19 drives the tertiary annular crushing plate 22 to move, and the power rod 9 drives the conical crushing head 10 to move, and the movement of the conical crushing head 10 adjusts the gap of the secondary crushing cavity, and the movement of the tertiary annular crushing plate 22 adjusts the gap between the crushing roller 24 and the tertiary annular crushing plate 22, so as to control the particle size of the crushed hydrogen storage alloy.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
