[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1: Please refer to Figures 1-4 , Figure 6 and Figure 7 The present invention provides a technical solution: an energy-saving and environmentally friendly wastewater treatment device for steel plants, including a treatment chamber 1, a filter media replacement mechanism 2 is provided on the outside of the treatment chamber 1, and a scraper replacement mechanism 3 is provided inside the treatment chamber 1.

[0036] The filter media replacement mechanism 2 includes a cleaning unit 21, which is located inside the treatment chamber 1. The cleaning unit 21 can automatically clean the filter media used for wastewater filtration.

[0037] As a further definition of the filter media replacement mechanism 2 of the present invention, the cleaning unit 21 includes a rotating plate 2110, the outer surface of which is rotatably connected to the inner wall of the processing chamber 1. Two filter cylinders 2115 are fixedly connected to the inner wall of the rotating plate 2110, and a filter bag 2114 is fixedly connected to the inner wall of each filter cylinder 2115. A first gear 2109 is fixedly connected to the bottom surface of the rotating plate 2110. A support plate 2103 is fixedly connected to the inner wall of the processing chamber 1. A first stepper motor 2108 is fixedly connected to the inner wall of the support plate 2103. A second gear 2116 is fixedly connected to the output end of the first stepper motor 2108. The outer surface of the second gear 2116 meshes with the outer surface of the first gear 2109. A first hydraulic rod 2118 is fixedly connected to the inner wall of the support plate 2103. A push plate 2119 is fixedly connected to the telescopic end of the first hydraulic rod 2118. The push plate 2119 is disposed below one of the filter bags 2114. By setting up the cleaning unit 21, the filter media inside the treatment chamber 1 that has been used for a period of time can be automatically cleaned, eliminating the tedious steps of manual cleaning of the filter media, greatly increasing the replacement efficiency of the filter media, reducing the standby time of the equipment, and further increasing the equipment's efficiency in treating sewage.

[0038] Please see Figures 1-4 A circular plate 2111 is fixedly connected to the inner wall of the treatment chamber 1. The upper surface of the circular plate 2111 is provided with a sewage inlet 2113 and a filter media inlet 2112. The outer surface of the treatment chamber 1 is provided with a discharge port 2101. The sewage to be treated can be transported into the interior of the treatment chamber 1 through the sewage inlet 2113. The presence of the filter media inlet 2112 allows new filter media to be transported into the filter bag 2114. The filter media that has been used for a period of time can be transported to the outside through the discharge port 2101.

[0039] Please see Figure 2 , Figure 3 , Figure 6 and Figure 7 A storage box 2104 is fixedly connected to the upper surface of the support plate 2103. The storage box 2104 is located in the inner cavity of the treatment chamber 1. An injection pipe 2105 is fixedly connected to the outer surface of the storage box 2104. One end of the injection pipe 2105 passes through the treatment chamber 1 and extends to the outside of the treatment chamber 1. A circular locking block 2102 is snapped into the inside of the injection pipe 2105. By setting the injection pipe 2105, the flocculant can be conveniently delivered into the storage box 2104.

[0040] Please see Figure 7A water pump 2106 is fixedly connected to the upper surface of the support plate 2103. The output end of the water pump 2106 is fixedly connected to an output pipe 2107, and the input end of the water pump 2106 is fixedly connected to an input pipe 2117. The end of the input pipe 2117 near the storage tank 2104 passes through the storage tank 2104 and extends into the interior of the storage tank 2104. By setting up the water pump 2106, the flocculant inside the storage tank 2104 can be easily extracted using the water pump 2106 and the input pipe 2117, and finally transported to the inside of the sewage.

[0041] The specific implementation method of this embodiment is as follows: When the equipment is in use, the notch on the upper surface of the rotating chamber 2201 corresponds to the notch on the surface of the fixed plate 2206. At this time, the sewage pipe can be aligned with the sewage inlet 2113 opened on the upper surface of the circular plate 2111, guiding the sewage down through the sewage inlet 2113 into the filter cylinder 2115 below the sewage inlet 2113. When the sewage enters the interior of the filter cylinder 2115, the quartz sand and activated carbon inside the filter cylinder 2115 will filter the impurities in the sewage. The filtered sewage will enter the interior of the treatment chamber 1. When it is necessary to perform flocculation treatment on the sewage inside the treatment chamber 1, the third stepper motor 303 is controlled to run. The running of the third stepper motor 303 will drive the first stepper motor 2115 to run the second stepper motor 2115. The sixth gear 304 rotates, and since the sixth gear 304 meshes with the fourth gear 308 and the fifth gear 306, the operation of the third stepper motor 303 can drive the stirring shaft 301 and the threaded shaft 307 to rotate synchronously, thus stirring the sewage inside the treatment chamber 1. During the stirring process, the water pump 2106 operates and can extract the flocculant from the storage tank 2104 through the input pipe 2117, and finally deliver it to the sewage inside the treatment chamber 1 through the output pipe 2107 to achieve the purpose of adding chemical agents. After the equipment has been used for a period of time, a large amount of impurities will be filtered out inside the filter cylinder 2115 located below the sewage inlet 2113. Therefore, it is necessary to regularly clean the quartz inside the filter cylinder 2115. When replacing the sand and activated carbon, the first stepper motor 2108 needs to be controlled. The first stepper motor 2108 drives the second gear 2116 to rotate. Utilizing the meshing relationship between the second gear 2116 and the first gear 2109, power is transmitted to the second gear 2116 and the rotating plate 2110, causing the rotating plate 2110 to rotate 180 degrees. When the rotating plate 2110 rotates 180 degrees, the positions of the two filter cylinders 2115 are swapped, causing the filter cylinder 2115 containing a large amount of impurities to rotate above the first hydraulic rod 2118. At this time, the first hydraulic rod 2118 is controlled to operate, which pushes the push plate 211. 9. Moving upwards, the filter bag 2114 inside the filter cylinder 2115 can be pushed upwards by the push plate 2119. It should be understood that only the uppermost part of the filter bag 2114 is fixed to the inner wall of the filter cylinder 2115. Therefore, the filter bag 2114 can be flipped upwards under the action of the first hydraulic rod 2118, so that the filter material accumulated inside the filter bag 2114 is pushed upwards until the filter bag 2114 is completely flipped under the action of the first hydraulic rod 2118 and the push plate 2119. At this time, the filter material inside the filter bag 2114 will move along the slope of the rotating plate 2110 towards the outlet 2101, and finally move to the outside of the treatment chamber 1 through the outlet 2101, thereby achieving the purpose of automatic removal of filter material.

[0042] Example 2: Please refer to Figures 1-5 The present invention provides a technical solution: an energy-saving and environmentally friendly wastewater treatment device for steel plants. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The filter media replacement mechanism 2 includes a filling unit 22, which is disposed on the outside of the treatment chamber 1. The filling unit 22 can fill the filter head with new filter media.

[0043] As a further definition of the filter media replacement mechanism 2 of the present invention, the filling unit 22 includes a rotating ring 2205, the outer surface of which is rotatably connected to the inner wall of the processing chamber 1. A rotating chamber 2201 is fixedly connected to the outer surface of the rotating ring 2205. Two injection ports 2204 are provided on the upper surface of the rotating chamber 2201, and two discharge ports 2207 are provided on the bottom surface of the rotating chamber 2201. Four sets of square plates 2208 are fixedly connected to the bottom surface of the rotating chamber 2201. Each set of square plates... There are two plates 2208 in total. The inner wall of each set of square plates 2208 is rotatably connected to a rotating shaft 2211. The outer surface of each rotating shaft 2211 is fixedly connected to a baffle 2209. Two baffles 2209 are located below two discharge ports 2207. The inner wall of the processing chamber 1 is fixedly connected to a fixing plate 2206. The upper surface of the fixing plate 2206 has a square opening 2210. The bottom surface of each baffle 2209 is in contact with the upper surface of the fixing plate 2206. By setting the filling unit 22, the filter material such as activated carbon and quartz sand can be filled into the filter bag 2114 in layers to achieve the purpose of automatic replacement of filter material. In addition, under the action of the first hydraulic rod 2118, the filter bag 2114 can be pushed up and down slightly to make each layer of filter material relatively uniformly filled.

[0044] Please see Figure 1 A fixing frame 2202 is fixedly connected to the outer surface of the processing chamber 1. A second stepper motor 2203 is fixedly connected to the inner wall of the fixing frame 2202. The output end of the second stepper motor 2203 is fixedly connected to the upper surface of the rotating chamber 2201. By setting the fixing frame 2202, the fixing frame 2202 can provide a fixing force to the second stepper motor 2203, and the operation of the second stepper motor 2203 can drive the rotating chamber 2201 to rotate.

[0045] The specific implementation of this embodiment is as follows: When new filter material needs to be filled into the filter bag 2114, the second stepper motor 2203 can be controlled to run. The operation of the second stepper motor 2203 can drive the rotating chamber 2201 fixed at its output end to rotate. It should be understood that the interior of the rotating chamber 2201 is divided into two spaces, which store activated carbon and quartz sand respectively. The bottom of each space is inclined, so the activated carbon and quartz sand will move towards the feed port 2207 under the action of gravity. However, the bottom of each feed port 2207 is blocked by a baffle 2209. Therefore, the quartz sand at this time... The quartz sand and activated carbon cannot descend through the feed inlet 2207 to below the rotating chamber 2201. As the second stepper motor 2203 continues to operate, it drives the rotating chamber 2201 to rotate. When the rotating chamber 2201 rotates two of the baffles 2209 below it to the square opening 2210 on the upper surface of the fixed plate 2206, the baffles 2209 are no longer in contact with the upper surface of the fixed plate 2206. Therefore, the baffles 2209 will flip downwards under gravity. At this point, the baffles 2209 are no longer directly below the feed inlet 2207 and will not interfere with the feed inlet 2201. 07 causes obstruction, so the activated carbon inside the rotating chamber 2201 moves downward through the feed port 2207 and eventually enters the filter bag 2114. When the activated carbon enters the filter bag 2114, the first hydraulic rod 2118 can operate to push the push plate 2119 upward, causing the filter bag 2114 to move upward a short distance. This cycle repeats, achieving the purpose of flattening the activated carbon inside the filter bag 2114. Subsequently, the second stepper motor 2203 runs in the opposite direction. At this time, the two baffles 2209 originally located inside the square opening 2210 will contact the fixed plate 2206. Therefore, the baffles 2209 will again... The process is then reversed. At this point, baffle 2209 will again cover the activated carbon feed port 2207. Then, two other baffles 2209 will enter the square opening 2210 and repeat the above operation. At this time, the feed port 2207 below the quartz sand will not be covered by the baffle 2209, so the quartz sand will descend through the feed port 2207 to the top of the original activated carbon. Similarly, the first hydraulic rod 2118 is controlled to run and flatten the quartz sand. Note that at this time, the second stepper motor 2203 needs to be reversed to make the activated carbon spread on the quartz sand layer again, thereby achieving the purpose of layer-by-layer laying and increasing the filtration effect.

[0046] Example 3: Please refer to Figure 2 , Figure 6 and Figures 8-10 The present invention provides a technical solution: an energy-saving and environmentally friendly wastewater treatment device for steel plants. The present invention makes corresponding improvements to the technical problems mentioned in the background art. The scraper replacement mechanism 3 and the filter media replacement mechanism 2 cooperate with each other, and the scraper replacement mechanism 3 can conveniently replace the scraper.

[0047] As a further definition of the scraper replacement mechanism 3 of the present invention, the scraper replacement mechanism 3 includes a stirring shaft 301. The outer surface of the stirring shaft 301 is rotatably connected to the inner wall of the processing chamber 1. A threaded shaft 307 is rotatably connected to the inner wall of the stirring shaft 301. A lifting plate 312 is threadedly connected to the outer surface of the threaded shaft 307. Two rotating shafts 314 are rotatably connected to the inner wall of the lifting plate 312. A scraper 302 is provided inside the lifting plate 312. The bottom surface of the scraper 302 is in contact with the inner bottom wall of the processing chamber 1. Cross grooves 316 are provided at the ends of the two rotating shafts 314 that are far apart from each other and on both sides of the scraper 302. Each pair of cross-shaped slots 316 are connected to a cross-shaped locking block 315. A third gear 317 is fixedly connected to the outer surface of one of the rotating shafts 314, and a toothed plate 318 is fixedly connected to the outer surface of the stirring shaft 301. By setting up a scraper replacement mechanism 3, workers can easily replace the scraper. By setting up a cleaning unit 21, a filling unit 22, and a scraper replacement mechanism 3, the problem of long downtime and reduced sewage treatment efficiency caused by the inconvenience of replacing filter media and scrapers that need to be replaced regularly can be effectively avoided.

[0048] Please see Figure 8 A fourth gear 308 is fixedly connected to the outer surface of the stirring shaft 301, and a fifth gear 306 is fixedly connected to the outer surface of the threaded shaft 307. Two support seats 313 are fixedly connected to the upper surface of the circular plate 2111. A third stepper motor 303 is fixedly connected to the inner wall of each support seat 313. A cross shaft 305 is fixedly connected to the output end of each third stepper motor 303. A sixth gear 304 is slidably connected to the outer side of each cross shaft 305. The outer surface of each sixth gear 304 meshes with the outer surfaces of the fourth gear 308 and the fifth gear 306. By setting the third stepper motor 303, the operation of the third stepper motor 303 can drive the sixth gear 304 to rotate. By utilizing the meshing relationship between the sixth gear 304 and the fourth gear 308 and the fifth gear 306, the stirring shaft 301 and the threaded shaft 307 can be driven to rotate. The stirring shaft 301 can be used to stir the sewage.

[0049] Please see Figure 8Each support 313 has a second hydraulic rod 310 fixedly connected to its inner wall. Each second hydraulic rod 310 has a bullseye bearing 309 fixedly connected to its telescopic end. The outer surface of each bullseye bearing 309 is in contact with the bottom end of the sixth gear 304. The inner wall of the stirring shaft 301 has two sliding grooves 311. The outer surface of the lifting plate 312 is slidably connected to the inside of the two sliding grooves 311. By providing the second hydraulic rod 310, the second hydraulic rod 310 can provide support force to the bullseye bearing 309, so that the bullseye bearing 309 can push the sixth gear 304 to move upward, thereby adjusting the sixth gear 304 to a position where it only contacts the fifth gear 306.

[0050] The specific implementation of this embodiment is as follows: When the scraper blade 302 needs to be replaced, the second hydraulic rod 310 is controlled to push the bullseye bearing 309 upward. The bullseye bearing 309 will push the sixth gear 304 upward until the sixth gear 304 moves to a position that only contacts the fifth gear 306. At this time, the operation of the third stepper motor 303 will only drive the fifth gear 306 and the threaded shaft 307 to rotate. Since the threaded shaft 307 has a rotational connection with the stirring shaft 301, the threaded shaft 307 can rotate freely. The surface of the threaded shaft 307 is threaded with a lifting plate 312, so the lifting plate 312 will drive the scraper blade to rotate. As the mud plate 302 moves upward, and the lifting plate 312 moves upward and passes the toothed plate 318, the third gear 317 will mesh with the teeth of the toothed plate 318. The number of teeth on the toothed plate 318 is one-quarter of the number of teeth on the third gear 317. Therefore, the mud scraper 302 will rotate 90 degrees, causing the mud scraper 302 to fold inside the stirring shaft 301. As the equipment continues to run, the mud scraper 302 will continue to move upward. Then, the operator can pull out the two cross-shaped locking blocks 315 to remove the discarded mud scraper 302 and then reinstall the new mud scraper 302 to achieve the purpose of quickly replacing the mud scraper 302.
