Taking the TiFe hydrogen storage alloy as an example, the use method of the hydrogen storage tank charging and jolt ramming device according to the embodiment of the invention after combining the specific application parameters is as follows:
referring to fig. 1, quantitative alloy powder is put into the tank body 21 according to the process requirement at intervals, in the first stage, about 25 to 30KG of quantitative alloy powder enters the hydrogen storage tank 2 through the feeding unit, when the weight in the hydrogen storage tank 2 reaches a first quality control point (i.e. the gravity sensor 6 senses a sensing signal), the gravity sensor 6 transmits a signal to the controller 5, and the controller 5 controls the feeding unit 1 to stop feeding; when the feeding unit 1 stops feeding, the first-stage tap compaction is performed, the controller 5 controls the rotational speed 2800 + 3000r/min, the acceleration is 0.5-1m/s, the vibration time is 5 minutes, the acceleration, the rotational speed, the tap compaction time and other parameters of the first-stage tap compaction are set, the controller 5 drives the vibrating piece 32 to drive the hydrogen storage tank 2 to tap, and when the set vibration time of the vibration stress meter 7 is over, the first-stage tap compaction is stopped, and the gas guide tube 22 is inserted into the hydrogen storage tank 2 (as shown in fig. 2).
After the vibration part 32 drives the hydrogen storage tank 2 to perform the first-stage compaction, the vibration stress gauge 7 feeds back a finishing signal to the controller 5, the controller 5 controls the vibration part 32 to stop vibrating, the alloy powder with about 180-220KG in the second stage enters the hydrogen storage tank 2 through the feeding unit, when the weight in the hydrogen storage tank 2 reaches a first quality control point (namely the gravity sensor 6 senses a sensing signal), the gravity sensor 6 transmits a signal to the controller 5, and the controller 5 controls the feeding unit 1 to stop feeding; when the feeding unit 1 stops feeding, the second-stage tap compaction is performed, the controller 5 controls the rotational speed 4200 and 4700r/min for preparing tap compaction in the second stage of the vibratory stress meter 7, the acceleration is 1.5-2m/s, and the vibration time is 5 minutes;
after the vibration is finished, the alloy powder with the weight of about 200-250KG in the third stage is continuously operated and enters the hydrogen storage tank 2, and then the third stage of compaction is carried out, namely the rotating speed is 3500-3700r/min, the acceleration is 1.0-1.5m/s, and the vibration time is 5 minutes;
after the vibration is finished, continuing the operation of the alloy powder with the temperature of about 480-530KG in the fourth stage to enter the alloy hydrogen storage tank 2, and then performing the compaction in the fourth stage, namely the rotating speed of 5500-5800r/min, the acceleration of 6.5-7.1m/s and the vibration time of 10 minutes;
after the vibration is finished, the alloy powder with the volume of about 180-220KG in the fifth stage is continuously fed into the alloy hydrogen storage tank 2, and then the compaction in the fifth stage is carried out, namely the rotating speed is 5300-5700r/min, the acceleration is 9.2-10.1m/s, and the vibration time is 15 minutes;
after the vibration is finished, the alloy powder with about 280-330KG in the sixth stage continues to enter the alloy hydrogen storage tank 2, and then the compaction in the sixth stage is carried out, namely the rotating speed is 5700-6200r/min, the acceleration is 12.6-13.5m/s, and the vibration time is 20 minutes;
after the vibration is finished, the alloy powder with about 280-330KG in the seventh stage continues to enter the alloy hydrogen storage tank 2, and then the compaction in the seventh stage is carried out, namely the rotating speed is 6500-7000r/min, the acceleration is 23.2-24.1m/s, and the vibration time is 30 minutes;
after the vibration is finished, the alloy powder with about 180-220KG in the eighth stage is continuously fed into the alloy hydrogen storage tank 2, and then the compaction in the eighth stage is carried out, namely the rotating speed is 7000-7500r/min, the acceleration is 43.2-43.8m/s, and the vibration time is vibration until the powder loading in the last stage is finished (the compaction time in the last stage is specifically determined according to the actual situation).
And when the compaction work of the last stage is finished and the sensing value of the gravity sensor 6 reaches the total mass required by the charging process, the charging compaction work of the tank body 21 is finished.
According to the hydrogen performance requirement of the fuel cell, the final tap density of the alloy hydrogen storage tank 2 can reach 4.2-4.5g/cm 3. Meanwhile, the alloy powder material in the invention is not limited to TiFe hydrogen storage alloy, and can also be other metal hydrogen storage alloy materials.
In practical application, after the charging and jolt ramming work of the tank body 21 is finished, the sealing cover of the hydrogen storage tank 2 is welded, and then the parts of the whole device are sequentially removed.
In summary, each stage has a fixed powder loading weight, which provides a basis for accurate later weight statistics, and ensures that the overall weight is within a reasonable range of the design of the structure, and each stage is vibrated according to the inherent rotating speed and acceleration, i.e. it is ensured that the alloy powder in the tank is in a uniform tap density along with the gradual increase of the weight, if the operation steps are not performed, the total amount of the alloy powder in the tank may not reach the expected target, and the overall tap density may have deviation, or be large or small, and influence on the hydrogen storage later activation test, thereby causing the change of the hydrogen storage density. Colloquially, if not done so, more weight is loaded than the equipment specified; the hydrogen storage density required by the product can not be achieved due to less loading. The natural tap density can not meet the requirement, the difficulty of the later activation process is increased, and more financial and material resources are required to be invested to make up.
However, because the charging quantity of each stage is different from the parameter to be tapped according to the requirements of the charging tap process, the controller 5 needs to set the total powder charging quantity parameter of each stage fed back by the gravity sensor 6 in advance, and simultaneously program and set the tap parameters of each stage in the vibration stress gauge 7 respectively. Therefore, the hydrogen storage tank charging tap device of the invention is not limited to the specific method of use described above.
Compared with the prior art, the hydrogen storage tank charging and vibrating device provided by the invention has the following beneficial effects:
according to the hydrogen storage tank charging compaction device, the controller 5, the gravity sensor 6, the vibration stress meter 7 and other parts are arranged, the charging quality control point and the compaction density control point are completely carried out automatically, the inaccuracy of the charging quality control point can be avoided, a large amount of field personnel are not required, the staged accurate powder charging of the hydrogen storage tank 2 is realized, the hydrogen storage tank 2 is ensured to be strictly executed according to the charging process, the compaction density is ensured to be accurate and effective, namely, the charging quality control point is accurate, the integral compaction density has no deviation, the field charging efficiency is high, and the field safety is high.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and any simple modifications and equivalent variations of the above embodiments according to the technical spirit of the present invention are within the scope of the present invention.
