Description

Technical Field

[0001] The present application relates to the technical field of hydrogen fuel cells, and in particular to a dust removal device for hydrogen fuel cells. Background Art

[0002] A hydrogen fuel cell is a power generation device that directly converts the chemical energy of hydrogen and oxygen into electrical energy. Its basic principle is the reverse reaction of water electrolysis, where hydrogen and oxygen are supplied to the anode and cathode respectively. After hydrogen diffuses outward through the anode and reacts with the electrolyte, it releases electrons and reaches the cathode through an external load. Hydrogen combustion cells are used in aerospace, automobiles, aircraft and other fields due to their advantages of no pollution, no noise and high efficiency. In the production process of hydrogen combustion cells, a lot of dust will be generated.

[0003] For example, in the prior art, the Chinese utility model patent with the authorization announcement number CN219597632U discloses "a dust removal device for hydrogen fuel cell production". In order to solve the problem that the existing dust removal device cannot effectively remove dust, the treated dust cannot be effectively collected and cleaned, and the dust in the box needs to be manually cleaned. The fan outlet is arranged at the upper end and cannot effectively suck in dust, which easily causes the dust to be stuck in the air inlet. The sealing ring is arranged at the interface of the dust pipe, the lower end of the water tank is provided with a nozzle outlet pipe, and the water tank is connected to the dust removal box through the nozzle outlet pipe, the lower end of the nozzle outlet pipe is provided with a water outlet pump, and the nozzle outlet pipe is connected to the water outlet pump, and the front end of the nozzle outlet pipe is provided with a plurality of nozzles, the lower end of the dust removal box is provided with a water inlet pipe, and the water tank is connected to the dust removal box through the water inlet pipe, the connection port of the water inlet pipe is provided with a water inlet filter, the outer side of the water inlet pipe is provided with a water inlet pump, and the water tank is provided with a water tank filter inside.

[0004] The dust removal device for hydrogen fuel cells in the prior art, including the above-mentioned one, has a dust funnel arranged inside the dust removal box, which relatively reduces the situation where dust flows into other corners after passing through the dust pipe and cannot be collected in a centralized manner. However, in actual use, the device still has some problems. Although a dust funnel is arranged, dust is still easily adhered to the filter conveyor belt and the dust funnel when the dust is sprayed with clean water. Such dust will not only affect the filtering effect of the dust funnel, but may also hinder the operation of the conveyor belt. In addition, the dust adhered to the filter conveyor belt also increases the difficulty of cleaning and maintenance.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0006] In order to solve the problems that still exist in the device in actual use, although a dust funnel is set up, dust is still easy to adhere to the filter conveyor belt and the dust funnel when the dust passes through the clean water spray. These dusts will not only affect the filtering effect of the dust funnel, but may also hinder the operation of the conveyor belt. In addition, the dust adhered to the filter conveyor belt also increases the difficulty of cleaning and maintenance. The present application provides a dust removal device for a hydrogen fuel cell.

[0026] A detachable collecting box 14 is also installed inside the box body 3, and a supporting plate 16 is fixed at the bottom end of the collecting box 14, and a filter screen 17 is placed on the supporting plate 16. A number of supporting rods 13 for supporting the collecting box 14 are fixed below the collecting box 14 inside the box body 3, and two pull rods 15 are installed on the inner wall of the collecting box 14. When in use, first, push the device to the position where dust removal is required through the handle 5, then open the water inlet 12 of the water tank 8, add an appropriate amount of clean water to the water tank 8, then start the water pump 7, so that the clean water is transported to the atomizing nozzle 9 through the hose, and then start the dust collector 6, and the dust collector 6 starts to work, connecting the inside and outside of the box body 3 through the bellows to form a negative pressure environment. The dust and impurities on the surface of the hydrogen fuel cell are sucked into the box body 3 under the action of negative pressure. When passing through the filter 17, these dust and impurities are filtered and remain in the collection box 14, and are subjected to dust removal treatment through the atomizing nozzle 9, so that they adhere to the collection box 14, and the filter 17 is used to prevent the dust from falling. As the dust removal process proceeds, the dust in the collection box 14 gradually increases, and clean water will flow into the box body 3 through the filter 17. When it is necessary to clean the collection box 14, the operator can remove the collection box 14 from the box body 3 by pulling the pull rod 15. Since the collection box 14 is detachable, it is very convenient to clean. After cleaning, just remove the collection box 14. The collecting box 14 is put back into the box body 3 and supported by the supporting rod 13, while ensuring that the filter screen 17 is located on the supporting sheet 16. In addition, in order to further improve the dust removal effect, the dust removal device for the hydrogen fuel cell in the embodiment of the present application is also provided with a water outlet 11. When the dust removal process is completed, the clean water inside the box body 3 can be discharged through the water outlet 11. In summary, the dust removal device for the hydrogen fuel cell disclosed in the embodiment of the present application realizes effective dust removal for the hydrogen fuel cell by arranging components such as an atomizing nozzle 9, a dust collector 6 and a collecting box 14. At the same time, the detachable design of the collecting box 14 makes the cleaning process more convenient, thereby improving the use efficiency and maintenance convenience of the device.

[0027] Reference Figure 2 Two pairs of clamping plates 10 are also fixed to the outer wall of the water outlet 11, which can conveniently fix the two suction heads on the dust collector 6.

[0028] Reference Figure 4 The outer wall of the box body 3 is connected to two screw rods 21 through a rotating shaft, and the outer walls of the two screw rods 21 are both threadedly installed with cones 22. A pair of knobs 23 are fixed to the top of the two cones 22. The outer wall of the cover 4 is fixed with two symmetrically distributed fixing blocks 18. The fixing blocks 18 are provided with conical grooves 19 for the cones 22 to be inserted.

The avoidance grooves 20 are communicated with the conical grooves 19, and the height of the screw rods 21 is greater than the height of the fixing blocks 18. When in use, the screw rods 21 are turned over to pass through the avoidance grooves 20 and are located at the center of the conical grooves 19. At this time, the cones 22 can be rotated clockwise to be inserted into the conical grooves 19, which can increase the stability of the cover 4 during installation and make it difficult to rotate, thereby increasing the overall sealing of the box body 3.

[0029] Reference Figure 4 The screw 21, the cone 22 and the fixing block 18 are made of metal; they are not easy to bend or break, and their service life can be extended.

[0030] Reference Figure 3 The outer wall of the pull rod 15 is provided with anti-slip grooves; it is convenient for the user to take out the collection box 14 from the inside of the box body 3 for cleaning.

[0031] Reference Figure 4 The width of the avoidance groove 20 is greater than the diameter of the screw rod 21, so as to facilitate the screw rod 21 to pass through.

[0032] The implementation principle of a dust removal device for a hydrogen fuel cell in an embodiment of the present application is as follows: when in use, first, push the device to the position where dust removal is required by using the handle 5, then open the water inlet 12 of the water tank 8, add an appropriate amount of clean water to the water tank 8, then start the water pump 7 to transport the clean water to the atomizing nozzle 9 through the hose, then start the dust collector 6, and the dust collector 6 starts to work, connecting the inside of the box body 3 with the outside through the bellows to form a negative pressure environment. Dust and impurities on the surface of the hydrogen fuel cell are sucked into the inside of the box body 3 under the action of negative pressure, and these dust and impurities are filtered and retained in the collection box 14 when passing through the filter 17, and are dust-removed by the atomizing nozzle 9, so that they adhere to the collection box 14, and the filter 17 is used to prevent dust from falling;

[0033] As the dust removal process proceeds, the dust in the collection box 14 gradually increases, and clean water will flow into the interior of the box body 3 through the filter screen 17. When the collection box 14 needs to be cleaned, the operator can pull the pull rod 15 to take the collection box 14 out of the box body 3. Since the collection box 14 is detachable, it is very convenient to clean.
