DETAILED DESCRIPTION

[0015] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0016] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0017] See also Figure 1 , Figure 2 as well as Figure 3The present embodiment provides a water filtering and impurity removal device for water-energy hydrogen production, including a filter box 10, a filter assembly 20, a scraper assembly 30, an air storage assembly 40 and a piston assembly 50. The filter box 10 is provided with a water inlet pipe 101 on the top, and the filter assembly 20 is rotatably arranged inside the filter box 10 for filtering the water injected into the filter box 10 through the water inlet pipe 101. The scraper assembly 30 is slidably arranged on the upper part of the filter assembly 20. The air storage assembly 40 and the piston assembly 50 are each provided with two groups. The two groups of the air storage assembly 40 are movably mounted on the left and right side walls inside the filter box 10, and the two groups of the piston assemblies 50 are respectively The two groups of piston assemblies 50 are arranged at the upper ends of the two groups of air storage assemblies 40, and are used to pump air into the two groups of air storage assemblies 40 respectively, thereby driving the filter assembly 20 to reciprocate inside the filter box 10. When the filter assembly 20 rotates clockwise to tilt, the scraper assembly 30 slides from left to right along the upper part of the filter assembly 20 to scrape the debris retained on the upper part of the filter assembly 20 to the right side of the filter assembly 20. When the filter assembly 20 rotates counterclockwise to tilt, the scraper assembly 30 slides from right to left along the upper part of the filter assembly 20 to scrape the debris retained on the upper part of the filter assembly 20 to the left side of the filter assembly 20.

[0018] Initially, the filter assembly 20 is in an inclined state with the left side higher than the right side inside the filter box 10. The scraper assembly 30 is affected by gravity and stays at the upper right end of the filter assembly 20. The piston assembly 50 on the right side is in a gas supply state to the gas storage assembly 40 on the right side, thereby making the gas storage assembly 40 on the right side in an expanded state, while the piston assembly 50 on the left side is in a gas extraction state to the gas storage assembly 40 on the left side, thereby making the gas storage assembly 40 on the left side in a contracted state. When it is necessary to filter and remove impurities from the water used for hydrogen production, the water can be injected into the filter box 10 from the water inlet pipe 101. After entering the filter box 10, the water can pass through the filter assembly 20 and then fall into the inner side of the filter box 10. The filter assembly 20 is at the bottom, while the debris in the water body is intercepted by the filter assembly 20 and retained on the upper part of the filter assembly 20. As the water level at the bottom of the filter box 10 rises, the air storage assembly 40 on the right side in an expanded state is affected by the buoyancy of the water body and moves upward compared to the filter box 10, thereby pushing the right end of the filter assembly 20 to make the filter assembly 20 rotate counterclockwise. When the filter assembly 20 rotates counterclockwise to a state where the left is lower and the right is higher, the scraper assembly 30 is affected by gravity and slides to the left along the upper part of the filter assembly 20, thereby scraping the debris retained on the upper part of the filter assembly 20 to the left position of the upper part of the filter assembly 20. During the sliding of the scraper assembly 30 to the left, the piston assembly 50 on the right pushes the air storage assembly 40 on the right The air inside the component 40 is evacuated, causing the air storage component 40 on the right to shrink in order to reduce the buoyancy of the water body on it. When the scraper component 30 slides to the left end of the filter component 20, the piston component 50 on the left side sends air into the air storage component 40 on the left side, causing the air storage component 40 on the left side to expand. When the air storage component 40 on the left side expands, the buoyancy of the water body on it increases and moves up compared to the filter box 10, thereby pushing the left end of the filter component 20 to rotate the filter component 20 clockwise. When the filter component 20 rotates clockwise to a state of left high and right low, the scraper component 30 slides to the right along the upper part of the filter component 20 under the influence of gravity, thereby scraping off the debris trapped on the upper part of the filter component 20 Towards the right side of the upper part of the filter assembly 20, as the scraper assembly 30 slides to the right, the piston assembly 50 on the left draws out the air inside the air storage assembly 40 on the left, causing the air storage assembly 40 on the left to shrink, so as to reduce the buoyancy of the water body on it. When the scraper assembly 30 slides to the right end of the filter assembly 20, the piston assembly 50 on the right sends air into the air storage assembly 40 on the right, causing the air storage assembly 40 on the right to expand again. This reciprocating cycle can achieve automatic scraping and cleaning of debris on the upper part of the filter assembly 20 to prevent the accumulation of debris in a certain area above the filter assembly 20, causing the filter assembly 20 to be blocked, thereby improving the filtering and impurity removal effect and filtering and impurity removal efficiency of the water body.

[0019] See also Figure 2 , Figure 3 as well as Figure 4In one embodiment, the filter assembly 20 includes a filter screen 201 and a frame 202, the filter screen 201 is fixedly embedded in the inner side of the frame 202, the side wall of the frame 202 is rotatably provided with a rotating shaft 203, and the end of the rotating shaft 203 away from the frame 202 is fixedly connected to the inner wall of the filter box 10, the scraper assembly 30 includes a U-shaped slide 301 and a scraper 302, the U-shaped slide 301 is slidably arranged on the upper part of the frame 202, and the scraper 302 is fixedly arranged at the bottom of the U-shaped slide 301 and contacts with the upper part of the filter screen 201.

[0020] After water is injected into the filter box 10 from the water inlet pipe 101, the water can pass through the filter screen 201 and then fall to the bottom of the inner side of the filter box 10, and the debris in the water is intercepted by the filter screen 201 and retained on the upper part of the filter screen 201, thereby achieving the filtration and removal of water debris; when the right piston assembly 50 sends air into the right air storage assembly 40 and drives the right air storage assembly 40 to expand, the right air storage assembly 40 moves up compared to the filter box 10, thereby pushing the right end of the frame 202 so that the frame 202 rotates counterclockwise compared to the rotating shaft 203. When the frame 202 rotates counterclockwise, it drives the filter screen 201 to rotate counterclockwise synchronously. When the filter screen 201 and the frame 202 rotate to the left low and right high state, the U-shaped slide plate 301 slides to the left along the upper part of the frame 202 , thereby driving the scraper 302 to slide to the left in contact with the upper part of the filter screen 201 to scrape the debris on the upper part of the filter screen 201 to the left; when the left piston assembly 50 sends air into the left air storage assembly 40 and drives the left air storage assembly 40 to expand, the left air storage assembly 40 moves up compared to the filter box 10, thereby pushing the left end of the frame 202 to make the frame 202 rotate clockwise compared to the rotating shaft 203, and the frame 202 rotates clockwise to drive the filter screen 201 to rotate clockwise synchronously. When the filter screen 201 and the frame 202 rotate to a state where the left is higher and the right is lower, the U-shaped slide plate 301 slides to the right along the upper part of the frame 202, thereby driving the scraper 302 to slide to the right in contact with the upper part of the filter screen 201 to scrape the debris on the upper part of the filter screen 201 to the right.

[0021] See also Figure 2 as well as Figure 3 In one embodiment, a guide rail 204 is fixedly provided on the upper edge of the frame 202 , and a guide rail groove (not shown in the figure) adapted to the guide rail 204 is opened at the end of the U-shaped slide 301 .

[0022] See also Figure 2 , Figure 3 , Figure 5 as well as Figure 6In one embodiment, a support plate 105 is fixedly provided on the inner wall of the filter box 10, and slots are provided at the left and right ends of the frame 202. The gas storage assembly 40 includes a first air pipe 401, an air bag 402, and a second air pipe 403. The first air pipe 401 vertically penetrates the support plate 105 and movably cooperates with the support plate 105. The second air pipe 403 is fixedly provided at the lower end of the first air pipe 401 and communicates with the first air pipe 401. The air bag 402 covers the outside of the second air pipe 403. The side wall of the second air pipe 403 has a plurality of air bags 402 and a plurality of air bags 403. The air hole 404 is connected to the inner cavity of the airbag 402, and a supporting cross bar 406 is fixedly provided on the side wall of the first air tube 401. A top rod 407 is fixedly provided on the upper part of the supporting cross bar 406. The piston assembly 50 includes a piston rod 501 and an elastic member 502. The lower end of the piston rod 501 is inserted into the first air tube 401 from the upper end of the first air tube 401, and the upper end of the piston rod 501 extends from the groove to above the frame 202. The elastic member 502 is arranged in the first air tube 401 to provide elastic support for the piston rod 501.

[0023] When the frame 202 and the filter screen 201 rotate to the left-low and right-high state, the U-shaped slide plate 301 slides to the left along the upper part of the frame 202. At this time, the U-shaped slide plate 301 is separated from the piston rod 501 corresponding to the right piston assembly 50, and the corresponding elastic member 502 pushes the piston rod 501 to move upward, thereby extracting the air inside the air bag 402 corresponding to the right air storage assembly 40 through the air hole 404 and the second air pipe 403 into the first air pipe 401, so that the right air bag 402 shrinks, thereby reducing the buoyancy of the water body, and the right The first air pipe 401, the second air pipe 403 and the contracted air bag 402 corresponding to the air storage component 40 move downward and reset compared to the inner wall of the filter box 10; when the U-shaped slide plate 301 slides to the left end position of the frame 202, the U-shaped slide plate 301 can act on the piston rod 501 corresponding to the left piston component 50, thereby driving the piston rod 501 to move into the first air pipe 401 corresponding to the left air storage component 40, so as to pressurize the air inside the first air pipe 401 to the corresponding second air pipe 403. When the air enters the second air pipe 403, the air in the second air pipe 403 is compressed. The airbag 402 can enter the inside through the corresponding air hole 404, thereby driving the airbag 402 corresponding to the left air storage component 40 to expand. When the airbag 402 expands, the buoyancy of the water body increases, thereby driving the corresponding second air pipe 403, the first air pipe 401, the supporting cross bar 406 and the top rod 407 to move upward. When the top rod 407 moves upward, it acts on the left end of the frame 202 and pushes the frame 202 to rotate clockwise compared to the rotating shaft 203. Until the frame 202 and the filter screen 201 rotate to the state of left high and right low, the U-shaped slide plate 301 slides rightward along the upper part of the frame 202, the U-shaped slide plate 301 separates from the piston rod 501 on the left, and the corresponding elastic member 502 pushes the piston rod 501 upward, thereby re-extracting the air inside the left airbag 402 through the air hole 404 and the second air pipe 403 to the inside of the first air pipe 401, so that the left airbag 402 shrinks, thereby reducing the buoyancy of the water body, and the first air pipe 401, the second air pipe 403 and the shrinking airbag 402 corresponding to the left air storage assembly 40 move downward and reset compared to the inner wall of the filter box 10;When the U-shaped slide plate 301 slides to the right end of the frame 202, the U-shaped slide plate 301 can act on the piston rod 501 corresponding to the right piston assembly 50, thereby driving the piston rod 501 to move toward the first air pipe 401 corresponding to the right air storage assembly 40, so as to pressurize the air inside the first air pipe 401 to the corresponding second air pipe 403. After the air enters the second air pipe 403, it can enter the airbag 402 through the corresponding air hole 404, thereby driving the airbag 402 corresponding to the right air storage assembly 40 to expand. When the airbag 402 expands, the buoyancy of the water increases, thereby driving the corresponding second air pipe 403, the first air pipe 401, the supporting cross bar 406 and the top rod 407 to move upward. When the top rod 407 moves upward, it acts on the right end of the frame 202 and pushes the frame 202 to rotate counterclockwise compared with the rotating shaft 203. In this reciprocating cycle, the frame 202 and the filter 201 can be automatically reciprocated, and the scraper 302 can slide reciprocatingly along the upper part of the filter 201 to automatically clean the debris on the upper part of the filter 201.

[0024] See also Figure 4 as well as Figure 5 In one embodiment, the left and right sides of the side wall of the U-shaped slide 301 are provided with inclined surfaces 303. When the U-shaped slide 301 slides to the right end along the upper part of the frame 202, the inclined surface 303 on the right side of the U-shaped slide 301 can act on the corresponding piston rod 501 of the right piston assembly 50, thereby pushing the piston rod 501 to move toward the corresponding first air pipe 401 to pressurize air into the right airbag 402. Similarly, when the U-shaped slide 301 slides to the left end along the upper part of the frame 202, the inclined surface 303 on the left side of the U-shaped slide 301 can act on the corresponding piston rod 501 of the left piston assembly 50, thereby pushing the piston rod 501 to move toward the corresponding first air pipe 401 to pressurize air into the left airbag 402.

[0025] See also Figure 3 In one embodiment, a stopper 405 is fixedly provided on the outside of the first air pipe 401. When the U-shaped slide plate 301 slides to the end position of the frame 202 and acts on the piston rod 501, the stopper 405 can act on the upper part of the support plate 105. The support plate 105 can provide support for the stopper 405, and then provide support for the first air pipe 401, so that the piston rod 501 can be stably pressurized and then smoothly move into the first air pipe 401, and then smoothly pressurize air into the airbag 402.

[0026] In one embodiment, the elastic member 502 may be a spring or a metal spring, which is not limited here.

[0027] See also Figure 1 as well as Figure 2In one embodiment, relatively distributed debris outlets 104 are provided on the left and right side walls of the filter box 10. When the frame 202 rotates to a left-higher-right-lower state, the right end of the frame 202 overlaps the debris outlet 104 on the right. As the U-shaped slide 301 and the scraper 302 slide to the right, the scraper 302 can push the debris on the upper part of the filter net 201 to the outside of the filter box 10 through the debris outlet 104 on the right. Similarly, when the frame 202 rotates to a left-lower-right-higher state, the left end of the frame 202 overlaps the debris outlet 104 on the left. As the U-shaped slide 301 and the scraper 302 slide to the left, the scraper 302 can push the debris on the upper part of the filter net 201 to the outside of the filter box 10 through the debris outlet 104 on the left.

[0028] See also Figure 1 In one embodiment, an overflow pipe 102 and a drain pipe 103 are provided on the side wall of the filter box 10 . A valve is provided in the drain pipe 103 . The drain pipe 103 is arranged below the overflow pipe 102 .

[0029] When the water level at the bottom of the inner side of the filter box 10 rises to a certain height, it can be discharged from the overflow pipe 102. Thereafter, the water level at the bottom of the inner side of the filter box 10 maintains a predetermined height. When the air bag 402 expands, it moves upward along the inner bottom of the water body of the filter box 10, thereby pushing the corresponding second air pipe 403, the first air pipe 401, the support cross bar 406 and the top rod 407 to move upward. The top rod 407 acts on the frame 202 to rotate the frame 202. When the air bag 402 shrinks, the corresponding second air pipe 403, the first air pipe 401, the support cross bar 406 and the top rod 407 drive the contracted air bag 402 to move downward along the inner side of the water body and reset. When the water body is filtered and impurities are removed, the valve inside the drain pipe 103 can be opened to release all the water inside the filter box 10.

[0030] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
