Technical Field

[0001] This utility model relates to the field of hydrogen recovery technology for hydrogen batteries, specifically to a hydrogen recovery device for hydrogen batteries with efficient impurity removal function. Background Technology

[0002] Hydrogen recovery systems for hydrogen fuel cells typically include modules for hydrogen collection, purification, storage, and reuse. They recover hydrogen from the exhaust gas of the fuel cell, remove impurities through a series of purification processes, and ultimately reinject high-purity hydrogen into the fuel cell, achieving hydrogen recycling.

[0003] According to the search, the Chinese patent "A Hydrogen Recovery and Utilization Device" authorized announcement number "CN221471341U" uses a cylinder, support rod and brush to clean the filter plate, making the filter plate less prone to clogging and ensuring the efficiency of hydrogen recovery.

[0004] In the aforementioned application, during the cleaning of the filter plate with a brush, some impurities on the filter plate adhere to the brush under the action of friction, which can easily cause the impurities on the brush to re-adhere to the filter plate, thereby affecting the cleaning effect of the filter plate.

[0005] Based on this, this utility model designs a hydrogen recovery device for hydrogen batteries with efficient impurity removal function to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a hydrogen recovery device for hydrogen batteries with efficient impurity removal function.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A hydrogen recovery device for hydrogen batteries with high-efficiency impurity removal function includes an impurity removal tank, a rotating shaft rotatably connected to the inner wall of the impurity removal tank, a filter plate fixedly connected to the upper end of the inner wall of the impurity removal tank, and a cleaning mechanism. The cleaning mechanism includes a long rod rotatably connected to the surface of the rotating shaft, annularly distributed cleaning plates slidably connected to the inner wall of the long rod, brushes evenly distributed at the ends of the cleaning plates, a fixing frame fixedly connected to the surface of the rotating shaft, a toggle plate slidably connected to the inner wall of the fixing frame, a first gear fixedly connected to the surface of the long rod, a connecting ring fixedly connected to the bottom end of the filter plate, and annularly distributed triangular blocks fixedly connected to the bottom end of the connecting ring.

[0009] Furthermore, an arc-shaped block is fixedly connected to the surface of the rotating shaft, and several sliders are fixedly connected to the surface of the arc-shaped block. A driven rod is fixedly connected to one side of the cleaning plate, and a first spring evenly distributed is fixedly connected to the end of the cleaning plate. The other end of the first spring is fixedly connected to the inner wall of the long rod.

[0010] Furthermore, the surface of the actuating plate is comb-shaped, and the ends of the brush are curved into an arc shape.

[0011] Furthermore, both the cleaning plate and the actuating plate are triangular in shape.

[0012] Furthermore, two support rods are fixedly connected to the surface of the long rod, and a support block is fixedly connected to the upper end of the surface of the actuating plate.

[0013] Furthermore, the bottom of the actuating plate is fixedly connected with a second spring that is evenly distributed, and the bottom end of the second spring is fixedly connected to the inner bottom wall of the fixed frame.

[0014] Furthermore, the surfaces of the slider and the support block are curved into an arc shape.

[0015] Furthermore, one end of the long rod is rotatably connected to a ball bearing, the surface of which is rotatably connected to the inner wall of the impurity removal tank.

[0016] Beneficial effects

[0017] 1. Through a rotating shaft, long rod, first gear, connecting ring, and triangular block, the long rod drives multiple sets of brushes to move and rotate in a ring to scrape the filter plate. The rotating brushes reduce the area on which impurities adhere. When one set of brushes rotates and contacts the actuating plate, it will deform, causing the attached impurities to be shaken off, ensuring the cleanliness of the brush surface. Compared with existing brushes where impurities will re-adhere to the filter plate during cleaning, this method achieves automatic cleaning of the brushes, avoiding the re-adhesion of impurities on the brushes to the filter plate, and ensuring the cleaning effect of the filter plate.

[0018] 2. Through the arc-shaped block, slider and driven rod, the cleaning plate is squeezed and moves longitudinally during the circular movement, squeezing the first spring. After the squeezing of the cleaning plate is released, the elastic force of the first spring will push the cleaning plate and brush to reset, so that the cleaning plate and brush shake off the attached impurities during the intermittent reciprocating lifting and lowering.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-4A hydrogen recovery device for hydrogen batteries with high efficiency in removing impurities includes an impurity removal tank 1, a rotating shaft 2 rotatably connected to the inner wall of the impurity removal tank 1, a filter plate 3 fixedly connected to the upper end of the inner wall of the impurity removal tank 1, and a cleaning mechanism 4. The cleaning mechanism 4 includes a long rod 41 rotatably connected to the surface of the rotating shaft 2, a ring-shaped cleaning plate 42 slidably connected to the inner wall of the long rod 41, brushes 43 evenly distributed fixedly connected to the end of the cleaning plate 42, a fixing frame 44 fixedly connected to the surface of the rotating shaft 2, a toggle plate 45 slidably connected to the inner wall of the fixing frame 44, a first gear 413 fixedly connected to the surface of the long rod 41, a connecting ring 414 fixedly connected to the bottom end of the filter plate 3, and a ring-shaped triangular block 415 fixedly connected to the bottom end of the connecting ring 414.

[0029] The brush 43 is made of nylon. The bottom of the impurity removal tank 1 is equipped with a base, and the top of the base is equipped with a storage tank. The top of the impurity removal tank 1 is connected to a pressure pump, and the other end of the pressure pump is connected to the top of the storage tank. The inner top wall of the impurity removal tank 1 is fixedly connected to filter cotton. The surface of the impurity removal tank 1 is connected to a water inlet pipe and a water outlet pipe. The inner wall of the impurity removal tank 1 is fixedly connected to an air inlet pipe, and the lower end of the surface of the air inlet pipe is provided with an air outlet. The inner wall of the rotating shaft 2 and the inner wall of the filter plate 3 are both fixedly connected to sealed bearings. The inner edge of one sealed bearing is fixedly connected to the surface of the air inlet pipe, and the inner edge of the other sealed bearing is fixedly connected to the surface of the rotating shaft 2. The upper end of the surface of the rotating shaft 2 is fixedly connected to a second gear. The top of the impurity removal tank 1 is rotatably connected to a third gear. The second gear and the third gear mesh. The top of the impurity removal tank 1 is fixedly connected to a servo motor, and the output shaft of the servo motor is fixedly connected to the top of the third gear.

[0030] In this embodiment of the utility model, after connecting the air inlet pipe to the hydrogen delivery pipe, the hydrogen that needs to be purified is delivered into the air inlet pipe and injected into the filtered water in the impurity removal tank 1 through the air outlet. The servo motor is manually turned on, and the output shaft of the servo motor rotates through the third gear and the second gear to drive the rotating shaft 2 to rotate. The rotating shaft 2 rotates and moves the filtered water in the impurity removal tank 1, so that the filtered water can fully contact the hydrogen, thereby making the filtered water better adsorb the impurities in the hydrogen. The hydrogen after preliminary filtration is filtered again through the filter plate 3 to reduce the impurity content in the hydrogen. The filtered hydrogen absorbs moisture through the filter cotton and is pressurized and delivered to the storage tank for storage by the pressurized air pump.

[0031] The rotation of the shaft 2 drives the long rod 41 to move in a ring. Since the toothed blocks on the first gear 413 are located at the spacing of the ring-distributed triangular blocks 415, the ring-moving long rod 41 drives the first gear 413 to move in a ring on the ring-distributed triangular blocks 415 and contact the surface of the triangular blocks 415, causing the first gear 413 to rotate in the ring movement, which in turn causes the long rod 41 to rotate in the ring movement, thereby driving multiple sets of cleaning plates 42 to rotate in a ring movement. The rotation of the cleaning plates 42 in the ring movement drives the brushes 43 to rotate in the ring movement, so that the brushes 43 clean the impurities on the filter plate 3. The rotating brushes 43 prevent impurities from adhering to a large area on them. One set of brushes 43 rotates and contacts the actuating plate 45. Since the brushes 43 have to pass through the actuating plate 45, the brushes 43 deform, thereby shaking off the impurities attached to the brushes 43, so that the surface of the brushes 43 cleans the filter plate 3.

[0032] In this embodiment of the utility model, the rotating shaft 2, the long rod 41, the first gear 413, the connecting ring 414 and the triangular block 415 enable the long rod 41 to rotate in a circular motion, thereby causing multiple sets of brushes 43 to move and rotate in a circular motion to scrape the filter plate 3. The rotating brushes 43 reduce the area on which impurities adhere. One set of brushes 43 rotates and contacts the actuating plate 45, causing the brushes 43 to deform. The attached impurities are shaken off due to the deformation of the brushes 43, ensuring the cleanliness of the brush surface and thus ensuring the cleaning effect on the filter plate 3. This ensures that the filter plate 3 can efficiently remove impurities from hydrogen.

[0033] In some embodiments, such as Figure 1-4 As shown, in a preferred embodiment of this utility model, an arc-shaped block 49 is fixedly connected to the surface of the rotating shaft 2, and a plurality of sliders 410 are fixedly connected to the surface of the arc-shaped block 49. A driven rod 48 is fixedly connected to one side of the cleaning plate 42, and a first spring 46 arranged in equal rows is fixedly connected to the end of the cleaning plate 42. The other end of the first spring 46 is fixedly connected to the inner wall of the long rod 41. Two support rods 411 are fixedly connected to the surface of the long rod 41. A support block 412 is fixedly connected to the upper surface of the actuating plate 45, and a second spring 47 arranged in equal rows is fixedly connected to the bottom of the actuating plate 45. The bottom end of the second spring 47 is fixedly connected to the inner bottom wall of the fixed frame 44. The surfaces of the sliders 410 and the support blocks 412 are curved into arc shapes. A ball bearing 416 is rolledly connected to one end of the long rod 41, and the surface of the ball bearing 416 is rolledly connected to the inner wall of the impurity removal tank 1.

[0034] In this embodiment of the utility model, the rotation of the long rod 41 drives the cleaning plate 42, the driven rod 48, and the support rod 411 to move in a ring. When the driven rod 48 contacts the arc surface of one of the sliders 410, the slider 410 will squeeze the driven rod 48 to move longitudinally. The longitudinally moving driven rod 48 drives the cleaning plate 42 and the brush 43 to move longitudinally and squeeze the first spring 46. When the driven rod 48 passes the slider 410, the elastic force of the first spring 46 pushes the cleaning plate 42 and the brush 43 to reset, so that the cleaning plate 42 and the brush 43 intermittently rise and fall to shake off the attached impurities. When the ring-moving support rod 411 contacts the arc surface of the support block 412, it will press down on the support block 412, so that the support block 412 drives the actuating plate 45 to move down and squeeze the second spring 47. When the support rod 411 passes the support block 412, the elastic force of the second spring 47 pushes the actuating plate 45 to move up, so that the actuating plate 45 rises and falls to shake off the attached impurities.

[0035] In this embodiment of the utility model, the arc block 49, the slider 410 and the driven rod 48 enable the cleaning plate 42 to be squeezed and move longitudinally during the circular movement, so that the longitudinally moving cleaning plate 42 squeezes the first spring 46. After the squeezing of the cleaning plate 42 is released, the elastic force of the first spring 46 will push the cleaning plate 42 and the brush 43 to reset, so that the cleaning plate 42 and the brush 43 shake off the attached impurities during the intermittent reciprocating lifting and lowering.

[0036] By using the support block 412 and the support rod 411, the long rod 41 intermittently drives the actuating plate 45 to move downward during rotation, causing the actuating plate 45 to squeeze the second spring 47 during downward movement. After the squeezing of the actuating plate 45 is released, the elastic force of the second spring 47 will push the actuating plate 45 upward, causing the actuating plate 45 to shake off the attached impurities during the intermittent reciprocating up and down movement.

[0037] In some embodiments, such as Figure 1-4 As shown, in a preferred embodiment of the present invention, the surface of the agitator plate 45 is comb-shaped, the end of the brush 43 is curved into an arc shape, and the cleaning plate 42 and the agitator plate 45 are both triangular in shape.

[0038] In this embodiment of the utility model, the comb-shaped agitator 45 increases the contact area of ​​the brush 43, which can better remove impurities attached to the brush 43. The curved end of the brush 43 reduces the contact area between impurities and the end of the brush 43, making it less likely for impurities to adhere firmly to the end of the brush 43, and thus allowing them to be removed more effectively.

[0039] It should be noted that the impurity removal tank 1, rotating shaft 2, filter plate 3, brush 43, storage tank, filter cotton, servo motor and pressure pump mentioned above are all components with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the servo motor and pressure pump can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0040] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
