[0002] Currently, during the operation of aluminum-water fuel cells, waste (such as aluminum hydroxide precipitation) is easily generated. Since the waste generated by aluminum-water fuel cells (including other aluminum-based fuel cells) has the property of precipitation, precipitation separation is required to prevent it from clogging the pipeline structure and inhibiting the electrochemical reaction. When applied in underwater mobile device platforms (such as near-surface buoy energy devices, underwater vehicle energy devices, deep-sea bottom energy base stations, unmanned underwater vehicles, etc.), most of the methods of filtering and storing the precipitate will greatly increase the volume of the fuel cell, and the specific energy will decrease sharply, causing the fuel cell to lose the advantage of high specific energy. At the same time, storing the precipitate will affect the electrolyte circulation and further affect the battery performance. Summary of the Invention

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1 - 11, a waste separation device for an aluminum-water fuel cell described in this embodiment includes a first outer shell 1, a second outer shell 2, a gear 3, a ratchet 5, and a torsion spring 14. The first outer shell 1 and the second outer shell 2 are assembled together and form an installation cavity 18, a filtration cavity 17, a liquid inlet channel 12, a liquid outlet channel 13, and a spiral channel 9 arranged around the installation cavity 18. The first outer shell 1 and the second outer shell 2 are fixed by bolts or welded, and each loop of the spiral channel 9 is located in the same plane. Generally, the spiral channel 9 is set to two loops, but not limited to this. The number of loops of the spiral channel 9 can be set according to actual situations. The through holes formed at the central positions of the first outer shell 1 and the second outer shell 2 are correspondingly assembled, and a bottom plate is fixedly blocked at the lower port of the second outer shell 2, thereby forming the installation cavity 18.

[0033] The liquid inlet channel 12 and the liquid outlet channel 13 are respectively communicated with the filtration cavity 17. The filtration cavity 17 is communicated with the outlet of the spiral channel 9. A plurality of deformable filter elements 10 are arranged in a spiral manner in the spiral channel 9. Concave portions 191 are formed on both the first outer shell 1 and the second outer shell 2. Spiral semi-cavities 91 recessed in the concave portions 191, filtration semi-cavities 171, first semi-channels 121, and second semi-channels 131 are formed. The two spiral semi-cavities 91 are symmetrically assembled to form the spiral channel 9, and the two concave portions 191 are symmetrically assembled to form a gap 19. The two filtration semi-cavities 171 are symmetrically assembled to form the filtration cavity 17. The two first semi-channels 121 are symmetrically assembled to form the liquid inlet channel 12. The two second semi-channels 131 are symmetrically assembled to form the liquid outlet channel 13. Thus, a gap 19 communicated with the installation cavity 18 and the spiral channel 9 is further formed between the first outer shell 1 and the second outer shell 2. A rotating disk 6 with a receiving cavity is arranged in the installation cavity 18. The torsion spring 14 is arranged in the receiving cavity. A plurality of push rods 161 arranged in an annular array are arranged on the rotating disk 6, and each push rod 161 is placed in the gap 19. Each push rod 161 is located between a plurality of deformable filter elements 10. The rotating disk 6 includes a rotating plate 61 and a connecting plate 62. An inner cavity is formed on the rotating plate 61. The connecting plate 62 is fixed at the port of the inner cavity on the rotating plate 61. The connecting plate 62 and the inner cavity form the receiving cavity. A sleeve is sleeved and fixed on the rotating plate 61. The rotating plate 61 and the sleeve are fixed by welding or bolts. A plurality of push rods 161 are integrally formed on the outer wall of the sleeve. A connecting block 621 is formed on the connecting plate 62.

[0034] A rotating shaft 4 is provided in the installation cavity 18. The rotating shaft 4 passes through the accommodating cavity and is fixed to the core end of the torsion spring 14. The outer end of the torsion spring 14 is bolted to the inner wall of the accommodating cavity. The gear 3 is located outside the first housing 1 and is sleeved and fixed to one end of the rotating shaft 4. The ratchet 5 is located outside the second housing 2. The central connecting portion on the rotating disk 6 passes through the installation cavity 18 and is bolted and fixed to the ratchet 5. The other end of the rotating shaft 4 passes through the installation cavity 18 and is inserted into the central hole of the ratchet 5. A first automatic lock 7 for locking or unlocking the gear 3 is provided outside the first housing 1, and a second automatic lock 8 for locking or unlocking the ratchet 5 is provided outside the second housing 2. The central connecting portion is a connecting block provided on the connecting plate 62.

[0035] The first automatic lock 7 includes a first spring 72, a first pawl 73, a first stop block 71, and a second stop block 74 located beside the gear 3. The tail ends of the first spring 72 and the first pawl 73 are placed between the first stop block 71 and the second stop block 74. The middle part of the first pawl 73 is rotatably mounted on the outside of the first housing 1. The two ends of the first spring 72 are respectively in contact with the first stop block 71 and the tail end of the first pawl 73. The tail end of the second stop block 74 abuts against the second stop block 74. The front end of the first pawl 73 is stuck between two adjacent convex teeth on the gear 3. The lower end of the first spring 72 is welded and fixed to the first stop block 71. Among two adjacent convex teeth of the gear 3, the lower convex tooth of the gear 3 contacts the inclined surface of the pawl, and the upper convex tooth of the gear 3 contacts the flat surface of the pawl for locking. The first stop block 71 and the second stop block 74 are fixed to the outside of the first housing 1 by welding or bolts. A first cover plate 11 is bolted to the housing of the first housing 1. The first cover plate 11 covers the first spring 72, the first pawl 73, the first stop block 71, and the second stop block 74 to play a dust-proof role.

[0036] The second automatic lock 8 includes a second spring 83, a second pawl 81, a third stop block 84, and an electromagnetic push rod 161 located beside the ratchet 5. The middle part of the second pawl 81 is rotatably mounted on the outside of the second housing 2. The driving part of the second pawl 81 and the second spring 83 are located between the third stop block 84 and the electromagnetic push rod 161. The telescopic rod of the electromagnetic push rod 161 abuts against the driving part of the second pawl 81. The two ends of the second spring 83 are respectively in contact with the third stop block 84 and the driving part of the second pawl 81. The front end of the second pawl 81 abuts against the ratchet teeth of the second ratchet 5. A blocking part 811 is provided on the second pawl 81. The lower end of the second spring 83 is welded and fixed to the third stop block 84. A second cover plate 20 is bolted to the housing of the second housing 2. The second cover plate 20 covers the second spring 83, the second pawl 81, the third stop block 84, and the electromagnetic push rod 161 to play a dust-proof role.

[0037] The ratchet teeth of the ratchet wheel 5 abut against the front end of the second pawl 81 to lock the ratchet wheel 5 and the rotating disk 6. The rotating shaft 4 is driven by a device such as a speed reducer to rotate counterclockwise, thereby driving the gear 3 to rotate counterclockwise to compress and store energy inside the coil spring 14. Due to the inclined surface provided on the first pawl 73, the gear 3 can rotate smoothly. After the energy storage is completed, under the action of the first spring 72, the tail end of the first pawl 73 is pushed, so that the tail end of the first pawl 73 abuts against the second stop block 74, and the front end of the first pawl 73 is embedded between two adjacent convex teeth of the gear 3 to position the gear 3, thereby preventing the rotating shaft 4 from rotating back due to the restoring force of the coil spring 14. Therefore, the restoring force of the coil spring 14 is applied to the rotating disk 6; when the filter element needs to be replaced, the telescopic rod of the electromagnetic push rod 161 extends to cause the second pawl 81 to tilt, so that the second pawl 81 moves away from the ratchet teeth of the gear 3. Then, under the action of the restoring force of the coil spring 14 applied to the rotating disk 6, the rotating disk 6 is driven to rotate counterclockwise, so as to drive the push rod 161 to rotate and move in the direction of the filter chamber 17, pushing the deformable filter element 10 near the filter chamber 17 into the filter chamber 17, and at the same time extruding the filter element already in the filter chamber 17 to replace the filter element in sequence. However, during filtration, the electrolyte enters through the liquid inlet channel 12 and is separated from waste through the deformable filter element 10 in the filter chamber 17 to filter out the precipitated electrolyte.

[0038] In this embodiment, the deformable filter element 10 includes a deformable porous filter body 101, terminals 102 respectively fixed at both ends of the deformable porous filter body 101, and a third spring 105 disposed inside the deformable filter body. Both ends of the third spring 105 abut against the two terminals 102 respectively. This structure of the filter element can be deformed to reduce the volume of the filter element, so as to achieve storage in a smaller volume, and further reduce the volume of the separation device.

[0039] Preferably, the pore diameter sizes of the pores in the deformable porous filter body 101 decrease in a stepped manner from one end of the deformable porous filter body 101 to the other end. That is, the position of the deformable porous filter body 101 located at the liquid inlet channel is a large pore diameter area, the middle part thereof is a medium pore diameter area, and the position thereof located at the liquid outlet channel is a small pore diameter area. Thus, the precipitate is filtered out and the precipitate is adsorbed or grows uniformly in a stepped manner from large to small according to the size on the inner hole surface of the filter element, making full use of the volume of the filter element and obtaining a relatively ideal electrolyte. And the deformable porous filter body is a porous medium with a relatively high porosity. Examples of such materials include, but are not limited to, polyester, polyether, polypropylene, polyacrylic acid, polystyrene, acrylonitrile-butadiene-styrene, polytetrafluoroethylene, or a flexible and elastic filter medium formed by mixing two or more of these materials, such as high-porosity polyurethane sponge, as Figure 15 shown.

[0040] Preferably, elongated grooves 103 matching the push rod 161 are formed on the surfaces of both terminals 102. The push rod 161 is embedded in the elongated grooves 103 to position the filter element, and the filter element can be pushed more stably. Sealing rings are sleeved on both terminals 102, and the outer walls of the sealing rings are in contact with the inner wall of the filter chamber 17.

[0041] Preferably, the diameters of both ends of the filter chamber 17 are smaller than the diameter of the middle part thereof, and the diameters of both ends of the filter chamber 17 are respectively consistent with the diameters of the filter channels. After the filter element enters the filter chamber 17, the outer walls of the two sealing rings are tightly fitted and sealed with the inner walls of both ends of the filter chamber 17, so that the filter element is effectively sealed in the filter chamber 17.

[0042] Please refer to Figures 12 - 14 , an aluminum-water fuel cell cabin described in this embodiment includes a housing 36, and a battery electronic control system 115, a solenoid valve group 118, a fuel cell stack 117, a pump group 116 and the aluminum-water fuel cell waste separation device 119 described above, which are placed in the housing 36; the battery electronic control system 115 includes a control module and a discharge amount monitoring module, and the discharge amount monitoring module and the electromagnetic push rod 161 of the aluminum-water fuel cell waste separation device are respectively connected to the control module and controlled by it.

[0043] In the above, the battery electronic control system 115 monitors the battery power, pressure, gas emission amount, etc. in real time. When the fuel cell stack 117 undergoes an electrochemical reaction to discharge and generate precipitates at the same time, when the internal precipitates accumulate to a set amount, through the opening and closing of the solenoid valve group 118, and in cooperation with the seawater injection device and the pump group 116, the electrolyte (including precipitates) is circulated. The electrolyte containing precipitates is extracted from the fuel cell stack 117 through a pipeline and enters the sealed filter chamber 17, and after passing through the filter element, it flows out through the liquid outlet channel and enters the fuel cell stack 117 to maintain the electrochemical reaction or the next-stage filtering device.

[0044] The discharge amount monitoring module monitors the discharge amount at the discharge end of the aluminum-water fuel cell compartment and transmits it to the control module. The control module determines whether the discharge amount reaches the threshold preset in the program according to the built-in program. When the preset threshold is reached, the electromagnetic push rod 161 is driven to replace the filter element of the aluminum-water fuel cell waste separation device. The control module controls the electromagnetic push rod 161 to make the ratchet 5 complete one step, and the lever rotates 60°. The compressed filter element is pushed backward. At the same time, the filter element extrudes the next saturated filter element (due to the thrust from the lever and the internal elastic force) until the sealing ring at one end of the filter element completes contact sealing, and contact sealing is also completed at the other end cross-section, then the filter element replacement is completed. The removed filter element is discharged through the outlet of the filter chamber. At the same time, an elastic funnel is connected to the outlet of the filter chamber. The diameter of the outlet of the filter chamber is the same as the diameter of the connection port of the elastic funnel. The diameter of the contraction port of the elastic funnel is 1 / 2 of the connection port (in the natural state) and has self-shrinking property, ensuring close contact between the contraction port and the filter element when the filter element is discharged to prevent seawater backflow. Since the substances contained in the saturated filter element are all harmless to the environment, the filter element can be freely discharged into the sea.

[0045] The present invention is not limited to the above best implementation mode. Anyone can obtain other various forms of products under the inspiration of the present invention. However, no matter what changes are made in its shape or structure, as long as it has the same or similar technical solutions as the present application, it will fall within the protection scope of the present invention.
