Taking TiFe hydrogen storage alloy as an example, the using method of the hydrogen storage tank material compaction device according to one embodiment of the application after combining specific application parameters is as follows:
referring to fig. 1, a fixed amount of alloy powder is put into the tank 21 according to the process requirement at intervals, the alloy powder with a fixed amount of about 25 KG to 30KG in the first stage enters the hydrogen storage tank 2 through the feeding unit, when the weight in the hydrogen storage tank 2 reaches the first quality control point (i.e. the gravity sensor 6 senses the sensing signal), the gravity sensor 6 transmits the 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 compaction is then performed, the controller 5 controls the rotation speed 2800-3000r/min of the vibration stress meter 7 at the first-stage preparation compaction, the acceleration is 0.5-1m/s, the vibration time is 5 minutes, the parameters such as the acceleration, the rotation speed and the compaction time of the first-stage preparation compaction are set, the controller 5 drives the vibrating piece 32 to drive the hydrogen storage tank 2 to perform compaction, when the set vibration time of the vibration stress meter 7 is over, the first-stage compaction is stopped, and the air duct 22 is inserted into the hydrogen storage tank 2 (as shown in fig. 2).
After the vibration piece 32 drives the hydrogen storage tank 2 to perform the compaction of the first stage, the vibration stress meter 7 feeds back an ending signal to the controller 5, the controller 5 controls the vibration piece 32 to stop vibrating, alloy powder of about 180-220KG of 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 an induction signal), the gravity sensor 6 transmits the 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 vibration stress meter 7 is subjected to vibration compaction in the second stage, and the controller 5 controls the rotation speed 4200-4700r/min, the acceleration of 1.5-2m/s and the vibration time of 5 minutes;
after the vibration is finished, carrying out the operation of the alloy powder of which the speed is about 200-250KG in the third stage, continuously entering the hydrogen storage tank 2, and then carrying out the compaction in the third stage, 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, the alloy powder of about 480-530KG in the fourth stage is continuously subjected to the operation and enters the alloy hydrogen storage tank 2, and then the compaction in the fourth stage is performed, namely the rotating speed is 5500-5800r/min, the acceleration is 6.5-7.1m/s, and the vibration time is 10 minutes;
after the vibration is finished, the alloy powder of which the speed is about 180-220KG in the fifth stage is continuously operated 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 of about 280-330KG in the sixth stage is continuously subjected to the operation and enters the alloy hydrogen storage tank 2, and then compaction in the sixth stage is performed, 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 of about 280-330KG in the seventh stage is continuously subjected to the operation and enters the alloy hydrogen storage tank 2, and then the compaction in the seventh stage is performed, 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 of about 180-220KG in the eighth stage is continuously subjected to the operation and enters the alloy hydrogen storage tank 2, and then compaction in the eighth stage, namely the rotating speed of 7000-7500r/min and the acceleration of 43.2-43.8m/s, is carried out, and the vibration time is that the vibration is stopped after the powder filling in the last stage is finished (the compaction time in the last stage is specifically determined according to practical situations).
After the compaction work of the last stage is completed 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 21 is completed.
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 application is not limited to TiFe hydrogen storage alloy, but can be other metal hydrogen storage alloy materials.
In practical application, after the charging compaction of the tank body 21 is completed, the sealing cover of the hydrogen storage tank 2 is welded, and then the parts of the whole device are sequentially removed.
In summary, since each stage has its fixed powder loading weight, this provides a basis for accurate statistics of specific weight afterwards, and also ensures that the overall weight is within a reasonable range of the design of the structure, and secondly, each stage is tapped according to its inherent rotational speed and acceleration, that is, it is ensured that the alloy powder in the can is in a uniform tap density along with the gradual increase of weight, if the above operation steps are not followed, the total amount of alloy powder in the can may not reach the desired target finally, and the overall tap density may deviate, be larger or smaller, and affect the later activation test, thereby causing the change of the hydrogen storage density. Colloquially, if not so, more weight is put than the equipment would dictate; the hydrogen storage density required by the product is not achieved due to less filling. The natural tap density can not meet the requirement, the difficulty of the later activation process is increased, and more finance and material resources are needed to be invested for compensation.
However, due to the requirement of the filling compaction process, the filling amount of each stage is different from the parameters required to be compacted, so that the controller 5 needs to set the parameters of the total filling amount of each stage fed back by the gravity sensor 6 in advance, and meanwhile, the compaction parameters of each stage in the vibration stress instrument 7 are programmed and set respectively. Therefore, the hydrogen storage tank material compaction device is not limited to the specific use method.
Compared with the prior art, the hydrogen storage tank filling compaction device provided by the application has the following beneficial effects:
according to the hydrogen storage tank filling compaction device, through arranging the parts such as the controller 5, the gravity sensor 6 and the vibration stress instrument 7, the filling quality control point and the compaction density control point are completely carried out by means of automation, so that inaccuracy of the filling quality control point can be avoided, a large number of personnel on site are not needed, staged accurate filling of the hydrogen storage tank 2 is realized, the hydrogen storage tank 2 is ensured to be strictly executed according to a filling process, the compaction density is ensured to be accurate and effective, namely, the filling quality control point is accurate, the overall compaction density is free from deviation, the site filling efficiency is high, and the site safety is high.
The foregoing description of the preferred embodiments of the present application is not intended to be limiting, but rather is merely illustrative of the present application, and all modifications and equivalents of the embodiments described above may be made in accordance with the technical spirit of the present application.
