Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, and particularly relates to a filter box for sewage treatment. Background Art

[0002] Sewage treatment filter boxes are used to remove impurities and harmful substances from wastewater through a layer-by-layer filtration process. These filter boxes typically consist of multiple filter stages, each containing a different type or level of filter material. Filter cotton is often used for primary filtration, adsorbing and retaining larger solid particles and suspended matter in the wastewater. The wastewater then passes through a more refined filtration zone below to further remove smaller particles and residual contaminants.

[0003] During use, the existing sewage treatment filter boxes are generally not equipped with a filter cotton replacement mechanism. The filtering effect of the filter cotton decreases after adsorbing pollutants, and it needs to be replaced frequently by manual labor to maintain the filtering effect. The convenience of sewage treatment is insufficient, and the drip plate during primary filtration is easily clogged and difficult to clean manually. The clogged drip plate easily blocks the flow of sewage from the primary filtration area to the lower filtration area, affecting the subsequent further filtration of sewage, and the reliability of sewage treatment is insufficient.

[0042] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following examples. It should be understood that the following text is only used to describe one or more specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0043] Example 1

[0044] like Figures 1 to 4 FIG2 is a first embodiment of the present invention, which provides a filter box for sewage treatment, including a box body 10; a water tank 20, which is arranged at the top of the box body 10 and is used for primary filtration of sewage, and the water tank 20 includes a water inlet pipe 21 and a drain outlet 22; a filter mechanism 30, which is arranged at the bottom of the water tank 20, and the filter mechanism 30 includes filter cotton 31, a drip plate 32, a material replacement component 33 and a water volume adjustment component 34, and is used to replace the filter cotton 31; a cleaning mechanism 40, which is arranged at the bottom of the filter mechanism 30 and is used to clean the drip plate 32, and the cleaning mechanism 40 includes a cleaning component 41; a driving mechanism 50, which is arranged at the top of the filter mechanism 30 and is used to drive the filter mechanism 30 and the cleaning mechanism 40.

[0045] It should be noted that the filter cotton 31 is rattan cotton with gaps inside for adsorbing and intercepting pollutants. Rattan cotton is a prior art and will not be described in detail here. A number of holes are provided inside the drip plate 32 for water to flow through the drip plate 32.

[0046] When the present invention is in use, sewage flows into the water tank 20 from the water inlet pipe 21 and flows into the box body 10 through the drain port 22. In the process of sewage moving from the water tank 20 to the box body 10, the filter cotton 31 in the filter mechanism 30 filters the sewage, and the filtered sewage drips into the box body 10 through the drip plate 32. When the filter cotton 31 needs to be replaced, the driving mechanism 50 drives the filter mechanism 30 to move after working, so that the material replacement component 33 rotates and drives different filter cotton 31 to move to the drain port 22, thereby realizing the switching of the filter cotton 31, reducing the situation of frequent manual replacement of the filter cotton 31, improving the convenience of sewage treatment, and at the same time, The amount regulating component 34 rotates under the water inlet pipe 21 to adjust the water inlet amount of the water inlet pipe 21, thereby reducing the overflow of sewage in the water tank 20 during the replacement of the filter cotton 31, and the driving mechanism 50 also drives the cleaning mechanism 40 to move after working, so that the cleaning component 41 moves along the drip plate 32 and cleans the drip plate 32, thereby reducing the need for manual cleaning of the drip plate 32 and the situation where the drip plate 32 is blocked and affects the flow of sewage from the water tank 20 to the box body 10, thereby improving the reliability of sewage treatment, and the filtering mechanism 30 and the cleaning mechanism 40 share a driving mechanism 50 as a driving source, which improves the linkage of the equipment compared with the traditional method.

[0047] Example 2

[0048] Reference Figures 1 to 10 , which is the second embodiment of the present invention, and is based on the previous embodiment.

[0049] like Figure 3 As shown, the water tank 20 further includes a shell 23 disposed on the top of the box body 10 , the water inlet pipe 21 is fixedly connected to the top of the shell 23 , and the drain outlet 22 is opened at the bottom of the shell 23 .

[0050] According to the above structure, sewage flows from the water inlet pipe 21 into the shell 23. The shell 23 serves as a temporary storage for the sewage, and allows the sewage to move from the drain outlet 22 through the filter mechanism 30 to the box 10 under the action of its own gravity, so that the filter mechanism 30 can perform primary filtration of the sewage.

[0051] like Figures 2 to 5As shown, the filtering mechanism 30 also includes a bottom plate 35 fixedly connected to the bottom of the shell 23, a drip plate 32 fixedly connected to the bottom of the bottom plate 35, the drip plate 32 is aligned with the drain outlet 22, the material changing assembly 33 is rotatably connected to the inside of the bottom plate 35, a plurality of filter cottons 31 are provided and are located inside the material changing assembly 33, a top plate 36 is fixedly connected to the top of the bottom plate 35, a rotating shaft 37 is fixedly connected to the inside of the material changing assembly 33, and a water volume regulating assembly 34 is fixedly connected to the end of the rotating shaft 37 close to the water inlet pipe 21, a loading assembly 38 is installed above the top plate 36, and a unloading assembly 39 is installed below the bottom plate 35.

[0052] It should be noted that the bottom of the bottom plate 35 is in contact with the top of the box body 10 .

[0053] According to the above structure, after the driving mechanism 50 drives the rotating shaft 37 to rotate, the rotating shaft 37 drives the material changing component 33 and the water volume regulating component 34 to rotate at the same time. When the material changing component 33 rotates, it drives the filter cotton 31 to rotate, so that different filter cottons 31 move to the bottom of the drain outlet 22, which is convenient for switching the filter cotton 31. In this process, the unloading component 39 receives the replaced filter cotton 31 that adsorbs pollutants, and the loading component 38 replenishes new filter cotton 31 into the interior of the material changing component 33. When the water volume regulating component 34 rotates, it adjusts the water inlet amount of the water inlet pipe 21. Since in the process of replacing the filter cotton 31, the water in the water tank 20 no longer flows into the box body 10 through the filter cotton 31, it is convenient to limit the water inlet amount of the water tank 20 to reduce the overflow of sewage in the water tank 20.

[0054] like Figures 3 to 6 As shown, the material changing assembly 33 includes a switching disk 331 rotatably connected to the base plate 35, and a plurality of first mounting grooves 332 and second mounting grooves 333 are provided inside the switching disk 331. The first mounting grooves 332 and the second mounting grooves 333 are arranged at intervals along the circumferential direction. A plurality of filter cottons 31 are provided and are respectively fixedly connected to the first mounting grooves 332, and a baffle 334 is fixedly connected to the inside of the second mounting groove 333.

[0055] It should be noted that, in the initial state, the first mounting groove 332 is aligned with the drain outlet 22 .

[0056] According to the above structure, after the rotating shaft 37 rotates, it drives the switching disk 331 to rotate, so that one first mounting groove 332 drives the filter cotton 31 that adsorbs pollutants to rotate to the unloading component 39 to discharge the filter cotton 31, and the other first mounting groove 332 drives the new filter cotton 31 from the loading component 38 to rotate to the drain outlet 22, thereby realizing the replacement of the filter cotton 31. During the movement of the first mounting groove 332, the second mounting groove 333 between the two first mounting grooves 332 rotates to the bottom of the drain outlet 22, so that the second mounting groove 333 blocks the drain outlet 22 and hinders the sewage from flowing downward. When the filter cotton 31 is not replaced, the situation where the sewage flows directly into the box body 10 without being filtered by the filter cotton 31 is reduced, thereby improving the reliability of replacing the filter cotton 31.

[0057] like Figures 3 to 5 As shown, the feeding assembly 38 includes a first cylinder 381 fixedly connected to the top of the top plate 36, a feeding port 361 is opened on the top plate 36, the first cylinder 381 is aligned with the feeding port 361, and multiple filter cottons 31 are provided and placed inside the first cylinder 381 in the vertical direction. A pressure plate 382 is provided above the filter cotton 31, and the pressure plate 382 is slidably connected to the inner wall of the first cylinder 381 in the vertical direction.

[0058] It should be noted that both ends of the pressure plate 382 are fixedly connected with sliding columns, and vertical sliding grooves are opened on the inner walls on both sides of the first cylinder 381. The vertical sliding grooves and the sliding columns slide together in the vertical direction. The cross-sectional shape of the sliding columns is rectangular, which is used to limit the pressure plate 382 to prevent the pressure plate 382 from flipping during the sliding process.

[0059] According to the above structure, when the switching disk 331 rotates, the first mounting groove 332 discharges the filter cotton 31 at the unloading assembly 39 and then rotates to the loading assembly 38. At this time, the first mounting groove 332 is aligned with the loading port 361 and the first cylinder 381. Since there is no filter cotton 31 inside the first mounting groove 332 and it is in a cavity state, the pressure plate 382 slides downward along the first cylinder 381 under the action of its own gravity. The pressure plate 382 pushes the filter cotton 31 in the first cylinder 381 to move downward, so that the new filter cotton 31 falls into the first mounting groove 332, thereby realizing the loading of the filter cotton 31, reducing the situation of manual loading of the filter cotton 31, and facilitating the replacement of the filter cotton 31 by the filter mechanism 30.

[0060] like Figures 2 to 10As shown, the blanking assembly 39 includes a connecting tube 391 fixedly connected to the bottom of the base plate 35, a blanking port 351 is provided at the bottom of the base plate 35, the connecting tube 391 is aligned with the blanking port 351, the lower end of the connecting tube 391 is slidably connected to the second cylinder 392 in the vertical direction, a limiting column 393 is fixedly connected to the outer wall of the connecting tube 391, a "J"-shaped slide groove 394 is provided on the inner wall of the upper end of the second cylinder 392, and the limiting column 393 slides in cooperation with the "J"-shaped slide groove 394.

[0061] It should be noted that the cross-sectional shape of the limiting column 393 is circular, and the second cylinder 392 is also rotatably matched with the connecting cylinder 391. In the initial state, the limiting column 393 is slidably inserted into the "J"-shaped sliding groove 394.

[0062] When the filter 31 adsorbs pollutants, it will fall through the discharge port 351 and fall into the second cylinder 392 under the action of its own gravity, so that the second cylinder 392 can store the filter 31. When the filter 31 adsorbs pollutants in the second cylinder 392 needs to be removed, the second cylinder 392 can slide and rotate along the connecting cylinder 391, so that the limit column 393 can slide along the "J"-shaped slide groove 394 and be pulled out from the top of the "J"-shaped slide groove 394, thereby separating the second cylinder 392 from the connecting cylinder 391, removing the second cylinder 392, and then taking out the filter 31 adsorbing pollutants in the second cylinder 392, so as to facilitate quick disassembly and assembly of the second cylinder 392 to remove the filter 31.

[0063] like Figures 3 to 6 As shown, the water volume regulating assembly 34 includes a rotating disk 341 fixedly connected to the upper end of the rotating shaft 37, the top of the rotating disk 341 fits with the end of the water inlet pipe 21, and a plurality of first mounting holes 342 and second mounting holes 343 are opened inside the rotating disk 341. The first mounting holes 342 and the second mounting holes 343 are arranged at intervals along the circumferential direction. The first mounting hole 342 corresponds to the first mounting groove 332, and the second mounting hole 343 corresponds to the second mounting groove 333. The first mounting hole 342 is fixedly connected to the inside of the first orifice plate 344, and the second mounting hole 343 is fixedly connected to the inside of the second orifice plate 345. The aperture size of the second orifice plate 345 is smaller than the aperture size of the first orifice plate 344.

[0064] It should be noted that, in the initial state, the first orifice plate 344 is in contact with the end of the water inlet pipe 21 , and the filter cotton 31 is aligned with the drain outlet 22 .

[0065] According to the above structure, after the rotating shaft 37 rotates, it drives the material changing component 33 and the water volume regulating component 34 to rotate synchronously. When the material changing component 33 drives the baffle 334 to rotate to the bottom of the drain outlet 22 and blocks the sewage from passing through the drain outlet 22, the water volume regulating component 34 drives the second orifice plate 345 to rotate to the bottom of the end of the water inlet pipe 21. At this time, the sewage in the water tank 20 can only flow in but not out. Since the aperture size of the second orifice plate 345 is smaller than the aperture size of the first orifice plate 344, the water inlet volume of the water inlet pipe 21 is reduced, thereby reducing the situation where the sewage in the water tank 20 overflows during the replacement of the filter cotton 31.

[0066] like Figure 2 、 Figure 7 and Figure 9 As shown, the cleaning mechanism 40 also includes an eccentric wheel 42 fixedly connected to the lower end of the rotating shaft 37, the outer side of the eccentric wheel 42 is rotatably connected to a sleeve 43, the side of the sleeve 43 close to the drip plate 32 is rotatably connected to a connecting rod 44, and the cleaning component 41 is arranged below the drip plate 32 and fixedly connected to the connecting rod 44, and the cleaning component 41 is slidably connected to the base plate 35.

[0067] According to the above structure, after the rotating shaft 37 rotates, it drives the eccentric wheel 42 to rotate, and the eccentric wheel 42 drives the sleeve 43 to rotate, so that the sleeve 43 drives the cleaning component 41 to move back and forth at the bottom of the bottom plate 35 through the connecting rod 44, thereby realizing the cleaning component 41 to clean the drip plate 32 and reduce the blockage of the drip plate 32.

[0068] like Figure 2 、 Figure 7 and Figure 9 As shown, the cleaning assembly 41 includes a connecting frame 411 fixedly connected to the connecting rod 44, the internal rotation of the connecting frame 411 is connected to a cleaning roller 412, the outer surface of the cleaning roller 412 is in rolling engagement with the drip plate 32, the bottom of the base plate 35 is fixedly connected to a strip slide 413, and the end of the cleaning roller 412 is in sliding engagement with the strip slide 413.

[0069] It should be noted that the cross-sectional shape of the end portion of the cleaning roller 412 is circular, and the end portion of the cleaning roller 412 is also rotatably engaged with the strip-shaped slide groove 413 .

[0070] According to the above structure, in the process of the connecting rod 44 driving the cleaning component 41 to move back and forth along the bottom plate 35, the connecting rod 44 first drives the connecting frame 411 to move back and forth, so that the cleaning roller 412 rotates inside the connecting frame 411, so that the connecting frame 411 drives the cleaning roller 412 to roll back and forth along the drip plate 32, thereby cleaning the drip plate 32. In this process, the end of the cleaning roller 412 cooperates with the strip slide 413, so that the process of the cleaning roller 412 moving along the bottom plate 35 is more stable.

[0071] like Figure 3 and Figure 4 As shown, the driving mechanism 50 includes a motor 51 fixedly connected to the top plate 36 , a driving gear 52 fixedly connected to the output end of the motor 51 , a driven gear 53 fixedly connected to the rotating shaft 37 , and the driving gear 52 and the driven gear 53 are meshed.

[0072] According to the above structure, when the driving mechanism 50 drives the filtering mechanism 30 and the cleaning mechanism 40, the output end of the motor 51 drives the driving gear 52 to rotate after working, and the driving gear 52 drives the rotating shaft 37 to rotate through the driven gear 53, so that the rotating shaft 37 drives the material changing component 33 and the water volume adjustment component 34 to rotate while also driving the eccentric wheel 42 to rotate, thereby realizing the driving mechanism 50 driving the filtering mechanism 30 and the cleaning mechanism 40 to move, which is convenient for reducing the number of driving sources used and reducing costs.

[0073] The working principle of the present invention is as follows: after the sewage enters the filter box, it first enters the water tank 20 and undergoes primary filtration through the filter mechanism 30 before flowing into the box body 10 for further filtration, wherein the filter cotton 31 adsorbs the pollutants in the sewage flowing down from the drain outlet 22, and then the sewage falls into the box body 10 through the drip plate 32. After the driving mechanism 50 works, the rotating shaft 37 drives the material changing component 33, the water volume adjustment component 34 and the eccentric wheel 42 to rotate, so that after the material changing component 33 rotates, the new filter cotton 31 is switched to the drain outlet 22, reducing the need for manual replacement of the filter cotton 31. After the water volume adjustment component 34 rotates, the water inlet volume of the water inlet pipe 21 is reduced, reducing the overflow of sewage in the water tank 20. After the eccentric wheel 42 rotates, it drives the cleaning component 41 to roll back and forth along the drip plate 32 and clean the drip plate 32, reducing the blockage of the drip plate 32 and improving the convenience of sewage treatment.

[0074] The foregoing is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained herein shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
