[0025] 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 without creative efforts shall fall within the protection scope of the present invention.
[0026] Please refer to Figures 1-6 , the present invention provides a technical solution for a floating bed for sewage treatment by the non-activated sludge method:
[0027] In the embodiment of the present invention, referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , one end of the motor 2 is provided with a water pumping component 3. The water pumping component 3 includes a first driving wheel 301 installed at one end of the motor 2. The outside of the first driving wheel 301 is sleeved with a transmission belt 302. The first driving wheel 301 is connected by transmission of the transmission belt 302 to a second driving wheel 303. One side of the second driving wheel 303 is provided with a first rotating shaft 304. The outer wall of the first rotating shaft 304 is provided with a rotating arm 305. The other end of the rotating arm 305 is also provided with a second rotating shaft. The rotating arm 305 is rotationally connected by the second rotating shaft to a push rod 306. One end of the push rod 306 is provided with a piston 307.
[0028] It should be noted that: The motor 2 is electrically connected to the storage battery. The driving pulley 301 connected to the motor 2 provides power to the entire pumping assembly 3. When the motor 2 is started, the driving pulley 301 installed at one end of the motor 2 starts to rotate. While rotating, it drives the transmission belt 302 to make the driving pulley 303 start to rotate. The rotating shaft 304 installed on one side of the driving pulley 303 starts to drive the rotating arm 305 to perform reciprocating displacement on a specified route, and makes the rotating arm 305 push the push rod 306. Since the rotating shaft 304 is installed at both ends of the rotating arm 305, it provides enough space for the linkage activity between the rotating arm 305 and the push rod 306. Subsequently, the push rod 306 starts to push the piston 307 to perform a fixed reciprocating route. A rubber pad is sleeved on the outer wall of the piston 307. Due to the elasticity of the rubber pad material, it can effectively fill the tiny gaps, improve the sealing performance, and reduce the direct friction between metals, reducing the wear rate.
[0029] Refer to Figure 1 As shown, heating plates 5 are installed on the inner front side wall, inner rear side wall, inner left side wall, and inner right side wall of the floating bed housing 1. Heating coils are laid inside the heating plates 5.
[0030] It should be noted that: The staff can turn on the heating plate 5 according to the needs of the region and temperature. When the water surface temperature is lower than 0 °C, after turning on the heating plate 5, it can prevent the floating bed housing 1 from losing its mobility after the water surface freezes. The heating plate 5 is electrically connected to the storage battery.
[0031] Refer to Figure 3 As shown, a water purification assembly 4 is arranged inside the floating bed housing 1. The water purification assembly 4 includes a water tank 401 installed inside the floating bed housing 1. Pipe 402 is installed on both opposite sides of the water tank 401. Valves 403 are installed at one end of each of the two pipes 402. One end of one pipe 402 far from the water tank 401 extends out from the bottom of the floating bed housing 1. A filter box 404 is installed at one end of the other pipe 402. A plurality of filter meshes 405 are installed inside the filter box 404. A pipe 403 is also installed on one side of the filter box 404. An anti-seepage baffle 406 is installed at one end of the pipe 403. A bracket 407 is installed on one side of the anti-seepage baffle 406.
[0032] It should be noted that the water tank 401 is slidably connected to the piston 307. One end of the water tank 401 is provided with a notch, and the size of the notch is adapted to the push rod 306. When the water pumping assembly 3 starts to move, the piston 307 starts to move horizontally in the water tank 401, so that one of the pipelines 402 starts to pump water from the water into the water tank 401. At this time, the valve 403 at the water pumping port is opened due to air pressure, while the valve 403 on the other side is closed. Subsequently, the piston 307 is pushed, the valve 403 at the water pumping port is closed, and the valve 403 on the other side is opened, so that the water enters the filter tank 404 through another pipeline 402. A plurality of filter meshes 405 are loaded in the filter tank 404, so that the water source is discharged through the anti-seepage baffle 406 after being purified by multiple layers. And the anti-seepage baffle 406 can prevent the external sewage from flowing back into the filter tank 404 through the outlet pipeline 403, resulting in a decrease in the purification efficiency.
[0033] Refer to Figure 5 As shown, the shape of the valve 403 is arc-shaped. One side of the valve 403 is provided with a mounting block, and a rotating shaft is arranged on the mounting block. The rotating shaft is rotatably connected to the inner wall of the pipeline 402.
[0034] It should be noted that: the shape of the valve 403 can better seal the pipeline 402 when it is closed, improving the sealing performance of the valve 403 for the pipeline 402. And the rotating shaft on one side of the valve 403 can enable the mounting block connected to the valve 403 to rotate on a precisely defined circular path, reducing deviation and swing. The rotating shaft helps to maintain stability during movement, reducing unnecessary friction and potential wear points, and extending the service life of the assembly.
[0035] Refer to Figure 6 As shown, there is a fixing block on one side of the anti-seepage baffle 406. The fixing block is installed in the middle of the bracket 407, and the shape of the bracket 407 is cross-shaped.
[0036] It should be noted that: the material of the anti-seepage baffle 406 is elastic rubber. The fixing block can stably fix the anti-seepage baffle 406 on the bracket 407, and can provide balanced support for the anti-seepage baffle 406, avoiding the displacement or damage of the baffle caused by uneven stress. The cross shape of the bracket 407 provides excellent stability and balance. The cross shape can ensure that the force is evenly distributed from the center to the surrounding, helping to disperse the pressure from different directions, reducing the material fatigue caused by stress concentration, and the four ends of the cross shape of the bracket 407 are all installed on the inner wall of the pipeline 403.
[0037] Working principle: After placing the floating bed housing 1 in water, the motor 2 drives the first driving wheel 301 to rotate. While rotating, the first driving wheel 301 drives the transmission belt 302 to make the second driving wheel 303 start to rotate. The first rotating shaft 304 installed on one side of the second driving wheel 303 starts to drive the rotating arm 305 to perform reciprocating displacement on a specified route, and makes the rotating arm 305 push the push rod 306. Since the first rotating shafts 304 are installed at both ends of the rotating arm 305, sufficient space is provided for the linkage activity between the rotating arm 305 and the push rod 306. Subsequently, the push rod 306 starts to push the piston 307 to perform a fixed reciprocating route. A rubber pad is sleeved on the outer wall of the piston 307, which can provide good sealing performance when the piston 307 moves horizontally inside the water tank 401, and also reduces the wear rate. A notch is opened at one end of the water tank 401, and the size of the notch is adapted to the push rod 306. When the pumping assembly 3 starts to move, the piston 307 starts to move horizontally in the water tank 401, so that one of the first pipes 402 starts to pump water from the water into the water tank 401. At this time, the pumping valve 403 is opened due to air pressure, and the valve 403 on the other side is closed. Subsequently, the piston 307 is pushed, the valve 403 at the pumping place is closed, and the valve 403 on the other side is opened, so that the water enters the filter box 404 through the other second pipe. A plurality of filter meshes 405 are loaded in the filter box 404, so that the water source is discharged through the anti-seepage baffle 406 after being purified through multiple layers, and the anti-seepage baffle 406 can prevent the external sewage from flowing back into the filter box 404 through the outlet pipe three, resulting in a decrease in the purification efficiency.
