[0011] Among them, the sand sedimentation and filtration mechanism includes a filter cage assembly. The filter cage assembly includes a mesh cylinder. A collar is arranged on one side of the inner wall of the mesh cylinder. One end of the mesh cylinder is fixedly installed on one side of the support disc.

[0012] Among them, the sand sedimentation and filtration mechanism includes a filtration component.

[0013] Among them, a cleaning plate for cleaning the debris between the filter sheets is provided on one side of the arc plate, and a medicine box is provided on one side of the cleaning plate.

[0014] The present invention provides a sewage treatment method with a sand sedimentation tank filtration structure: when sewage enters the interior of the water inlet tank, the rotary grille cleans the large debris on the surface of the sewage. The treated sewage flows to the lower part of the reel mechanism, and the provided sand sedimentation and filtration mechanism rotates continuously. The water absorption mechanism continuously pumps the sewage in the water inlet tank. Since the provided water absorption mechanism is inside the sand sedimentation and filtration mechanism, when the water absorption mechanism pumps sewage, the debris in the sewage is first filtered by the sand sedimentation and filtration mechanism and then sent to the grading sedimentation tank through the water absorption mechanism. And the provided cleaning mechanism can also timely clean the debris adsorbed on the surface of the sand sedimentation and filtration mechanism.

[0015] In summary, the technical effects and advantages of the present invention:

[0016] 1. In the present invention, the sewage is first preliminarily filtered through the rotating blades with a specific inclined shape and water filtering holes. It can not only effectively intercept larger particulate matters, but also promote the uniform distribution of water flow through the rotation of the rotating blades, reducing the possibility of blockage. After preliminary filtration, the sewage will be more finely filtered through the mesh cylinder. Since the mesh cylinder rotates with the support disk, it can continuously change the filtration area at the corresponding position of the enclosure, thus ensuring the balance and high efficiency of the filtration process. The rotating blades are designed to be inclined, which is convenient for the subsequent brush plate to clean the debris accumulated on the rotating blades, simplifies the cleaning process, and reduces the need for manual intervention. As the device operates, the cleaning tooth plate can automatically clean the debris in the filter sheet gaps and send these debris into the garbage chute plate, not only maintaining the high-efficiency operation state of the filter sheets, but also avoiding the performance decline caused by debris accumulation. And the design of the mesh cylinder rotating with the support disk makes the filtration area constantly change. This characteristic helps to prevent the rapid wear or blockage problem caused by overuse of a certain fixed area, extends the service life of the equipment and maintains a stable treatment efficiency.

[0017] 2. Before the sewage enters the sealed shell in the present invention, it first passes through a honeycomb filter. The honeycomb structure provides a large surface area, which can effectively intercept fine particles while maintaining a high water flux, enabling the sewage to quickly penetrate into the sealed shell, improving the overall filtration efficiency. When the support disk rotates, it drives a plurality of arc plates to rotate together. These arc plates not only play a mechanical support role but also clean the debris between the filters through the connected cleaning plates, preventing blockage and ensuring the smoothness of the water flow channel. As the arc plates rotate, the cleaning plates continuously move, effectively removing the debris between the filters and sending it into the garbage chute plate, reducing the need for manual cleaning and ensuring the continuous operation of the system. The medicine box is filled with flocculant. As the arc plates rotate, the medicine box also moves accordingly. Appropriate addition of flocculant helps to coagulate the fine suspended solids in the sewage, making them easier to be filtered or precipitated. The design of the sealed shell defines the specific spatial area for extracting sewage, enabling the sewage to more quickly penetrate into the sealed shell through the honeycomb filter, enhancing the local flow rate and filtration efficiency.

[0018] 3. In the present invention, when the sewage passes through the sand sedimentation and filtration mechanism, larger debris particles are blocked outside. Subsequently, the hollow tube is driven to rotate by the conveyor wheel, and the hollow tube then drives the brush plate to rotate to clean the surface of the sand sedimentation and filtration mechanism, ensuring that the sand sedimentation and filtration mechanism can continuously and effectively work without reducing efficiency due to debris accumulation. The debris cleaned from the surface of the sand sedimentation and filtration mechanism is sent into the garbage chute plate for centralized treatment. Moreover, components such as the pump, baffle, connecting pipe, shaft pipe fitting, hollow tube, and nozzle use the pump to pump out the water in the garbage chute plate and re-introduce it into the middle pipe. After passing through components such as the baffle and connecting pipe, it is finally sprayed out through the nozzle for cleaning the surface of the brush plate and the sand sedimentation and filtration mechanism, not only realizing the recycling of water resources, reducing the consumption of fresh water, but also ensuring the cleanliness of the cleaning tools themselves.

[0019] 4. In the present invention, since the water pipe is closely attached to the inner wall of the sand sedimentation and filtration mechanism, when the pump works to extract sewage, it can increase the penetration rate of the sewage through the sand sedimentation and filtration mechanism, enabling the sewage to pass through the sand sedimentation and filtration layer more quickly, accelerating the overall filtration speed. The design of the sealed shell helps to guide the flow direction of the sewage, ensuring that the sewage is evenly distributed and extracted through the covered area. The guiding vanes further help to adjust the water flow direction, enabling the sewage to enter the water inlet more smoothly and finally enter the pump through the water pipe. Since the sewage is forced to pass through the sand sedimentation and filtration mechanism instead of flowing naturally, this method not only improves the filtration speed but also increases the chance of contact between the particulate matter and the filtration medium, thereby enhancing the filtration effect.

Specific implementation mode

[0044] 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 work fall within the protection scope of the present invention.

[0045] Embodiment 1. Refer to Figures 1 to 22A sewage treatment device with a grit chamber filtration structure as shown includes a water inlet tank 2. Inside one side of the water inlet tank 2, a rotary grille 3 is provided. At one end of the water inlet tank 2, a grading sedimentation tank 1 is provided. Inside the water inlet tank 2 and below the rotary grille 3, a reel mechanism 6 is provided. At the upper end of the reel mechanism 6, an inclined plate 4 is provided. Inside the cavity of the reel mechanism 6, a grit filtration mechanism for cleaning sediment is provided. Inside the reel mechanism 6, a water suction mechanism 10 for pumping the sewage inside the water inlet tank 2 into the grading sedimentation tank 1 is provided. On one side of the reel mechanism 6, a garbage chute plate 5 is provided. Inside the garbage chute plate 5, a cleaning mechanism 8 for cleaning the sundries deposited on the surface of the grit filtration mechanism is provided.

[0046] It should be noted that when the sewage enters the inside of the water inlet tank 2, the rotary grille 3 cleans the large sundries on the surface of the sewage. The treated sewage flows to the lower part of the reel mechanism 6, and the provided grit filtration mechanism rotates continuously. The water suction mechanism 10 continuously pumps the sewage inside the water inlet tank 2. Because the water suction mechanism 10 is inside the grit filtration mechanism, when the water suction mechanism 10 pumps the sewage, the sundries in the sewage are first filtered by the grit filtration mechanism and then sent to the grading sedimentation tank 1 through the water suction mechanism 10. And the provided cleaning mechanism 8 can also timely clean the sundries adsorbed on the surface of the grit filtration mechanism.

[0047] Among them, the rotary grille 3 can clean the large sundries on the surface of the sewage, which can prevent the large sundries from blocking the subsequent treatment equipment or affecting the treatment efficiency. The continuous rotation of the grit filtration mechanism helps to separate the sand grains and other heavier particulate matters in the sewage. And the water suction mechanism 10 is located inside the grit filtration mechanism, and it pumps the preliminarily filtered sewage to ensure the sewage with larger particles and sand grains removed.

[0048] Since the water suction mechanism 10 directly pumps the filtered sewage from the grit filtration mechanism and sends it to the grading sedimentation tank 1, the filtration process is simplified and the overall treatment efficiency is improved. In addition, by sending the treated water to the grading sedimentation tank 1, the further separation and precipitation of pollutants with different sizes and densities are realized, thereby improving the effect of water quality purification.

[0049] Embodiment 2: According to the reel mechanism 6 and the cleaning mechanism 8 described in the embodiment, this embodiment specifically describes the further technical solutions of the reel mechanism 6 and the cleaning mechanism 8.

[0050] The reel mechanism 6 includes a mounting shell 61. The mounting shell 61 is installed at the upper end of the water inlet tank 2. The inclined plate 4 is installed at the upper end of the mounting shell 61, and the rotary grille 3 is arranged on one side of the mounting shell 61. On one side of the mounting shell 61, a driving motor 7 and a pump 9 are provided. The garbage chute plate 5 is installed on one side of the mounting shell 61.

[0051] It should be noted that after the sewage flows into the interior of the water inlet tank 2, sundries on the surface of the sewage are removed by the rotary grille 3, and the sundries will fall onto the surface of the inclined plate 4. The inclined plate 4 is arranged obliquely so that the sundries can fall into the interior of the garbage chute plate 5. Moreover, the installed mounting shell 61 is installed above the water inlet tank 2, enabling the filter sheet 65 to extend into the interior of the water inlet tank 2 to preliminarily filter the sewage that is about to be pumped by the garbage chute plate 5.

[0052] The reel mechanism 6 further includes a central rod 67 and a transmission wheel 64. One end of the central rod 67 is connected to the output end of the drive motor 7. A central wheel 63 is provided at one end of the central rod 67. A conveyor belt 62 is sleeved on the outer surfaces of the transmission wheel 64 and the central wheel 63. A plurality of filter sheets 65 are arranged at equal intervals on the inner bottom of the mounting shell 61. A fixed collar 66 is provided on the inner wall of the mounting shell 61 near the drive motor 7. A support disc 68 is provided on one side of the outer surface of the central rod 67.

[0053] Among them, a plurality of filter sheets 65 are provided to block larger particulate sundries in the sewage. When the drive motor 7 drives the central rod 67 to rotate, the central rod 67 will drive the central wheel 63 to rotate, and the central wheel 63 will drive the transmission wheel 64 to rotate through the conveyor belt 62. The rotation of the transmission wheel 64 drives the cleaning mechanism 8 to rotate to clean the surface of the sediment filtration mechanism.

[0054] Among them, the sewage first removes large sundries on the surface through the rotary grille 3, effectively preventing the large sundries from entering the subsequent treatment stage and preventing blockage or damage to the equipment. The sundries intercepted by the rotary grille 3 will slide onto the obliquely arranged inclined plate 4 and finally fall into the garbage chute plate 5, ensuring the effective collection and cleaning of the sundries and reducing the need for manual intervention.

[0055] Multiple filter sheets in the mounting shell 61 extend into the interior of the water inlet tank 2 to preliminarily filter the sewage that is about to be pumped. These filter sheets can block larger particulate sundries, further purify the water quality, and reduce the load of subsequent treatment steps. Moreover, the mechanical linkage system composed of the drive motor 7, the central rod 67, the central wheel 63, the conveyor belt 62, and the transmission wheel 64 is designed such that when the drive motor 7 starts, it can drive the cleaning mechanism 8 to rotate through a series of mechanical transmissions. The cleaning mechanism 8 can clean the surface of the sediment filtration mechanism to remove the sundries attached to it. The realization of automatic cleaning not only improves the continuous operation ability of the system but also reduces the maintenance cost.

[0056] The cleaning mechanism 8 includes a hollow tube 87 rotatably installed inside the garbage chute plate 5. One end of the hollow tube 87 is fixedly connected to the conveyor wheel 64. A plurality of brush plates 85 are arranged on the outer surface of the hollow tube 87. A plurality of spray nozzles 88 are formed on the outer surface of the hollow tube 87, and the spray nozzles 88 are located between every two brush plates 85. The hollow tube 87 is rotatably installed inside the garbage chute plate 5 through a bearing.

[0057] The cleaning mechanism 8 includes a middle-through tube 81. One side inside the hollow tube 87 is provided with a shaft pipe part 86, and a shaft connecting pipe 84 is sleeved on the outer surface of the shaft pipe part 86. One end of the shaft connecting pipe 84 is connected with a connecting pipe 83. One end of the connecting pipe 83 is connected to the middle-through tube 81, and the connecting pipe 83 is communicated with the inside of the middle-through tube 81. A baffle 82 is arranged inside the middle-through tube 81. One end of the middle-through tube 81 is connected to the pump 9.

[0058] It should be noted that after the sand sediment filtering mechanism filters the sundries in the sewage, the conveyor wheel 64 will drive the hollow tube 87 to rotate, and the hollow tube 87 will drive the brush plates 85 to rotate to clean the surface of the sand sediment filtering mechanism. The sundries on the surface of the sand sediment filtering mechanism are cleaned and sent into the garbage chute plate 5. The pump 9 pumps out the water inside the garbage chute plate 5 and sends it into the inside of the middle-through tube 81. The provided baffle 82 is used to separate part of the sewage and send it into the inside of the connecting pipe 83. Then the sewage passes through the connecting pipe 83 and the shaft pipe part 86 and is sent into the inside of the hollow tube 87. The water sprays out through the spray nozzles 88 and sprays on the surface of the brush plates 85. The sewage sprayed out through the spray nozzles 88 cleans the brush plates 85, so that the brush plates 85 can continuously maintain effective cleaning. And the sewage sprayed out through the spray nozzles 88 will also spray on the surface of the sand sediment filtering mechanism to ensure that the sand sediment filtering mechanism has continuous filtering ability.

[0059] Among them, when the sewage passes through the sand sediment filtering mechanism, larger particles of sundries are blocked outside. Subsequently, the conveyor wheel 64 drives the hollow tube 87 to rotate, and the hollow tube 87 drives the brush plates 85 to rotate to clean the surface of the sand sediment filtering mechanism, ensuring that the sand sediment filtering mechanism can continuously and effectively work without reducing efficiency due to the accumulation of sundries.

[0060] The sundries cleaned from the surface of the sand sediment filtering mechanism will be sent into the garbage chute plate 5 for centralized treatment. Moreover, these components such as the pump 9, the baffle 82, the connecting pipe 83, the shaft pipe part 86, the hollow tube 87 and the spray nozzles 88 use the pump 9 to pump out the water inside the garbage chute plate 5 and re-introduce it into the inside of the middle-through tube 81. After passing through components such as the baffle 82 and the connecting pipe 83, it is finally sprayed out through the spray nozzles 88 for cleaning the surface of the brush plates 85 and the sand sediment filtering mechanism. This not only realizes the recycling of water resources, reduces the consumption of fresh water, but also ensures the cleanliness of the cleaning tools themselves.

[0061] Embodiment 3. Based on the water absorption mechanism 10 described in Embodiment 1, this embodiment provides a further technical solution for the water absorption mechanism 10.

[0062] The water absorption mechanism 10 includes a support frame 101, which is fixedly installed on one side of the inner wall of the installation shell 61 and is installed on the outer surface of the central rod 67 through a bearing. A water pipe 102 is provided at the bottom of the support frame 101. A sealing shell 103 is provided on the outer surface of the water pipe 102. A number of water inlets 105 are opened on one side of the outer surface of the water pipe 102. A number of guide vanes 104 are provided on one side of the outer surface of the water pipe 102, and the guide vanes 104 are located inside the sealing shell 103. One end of the water pipe 102 is connected to the pump 9.

[0063] It should be noted that when treating sewage, the pump 9 pumps the sewage inside the water pipe 102. The sewage enters the water inlets 105 through the guidance of the sealing shell 103 and the guide vanes 104, and then the sewage enters the inside of the pump 9 through the water pipe 102. The provided sealing shell 103 guides the flow direction of the sewage, so that the water pipe 102 pumps the sewage according to the covered area of the sealing shell 103. Since the provided water pipe 102 is attached to the inner wall of the sedimentation and filtration mechanism, the permeability of the sewage passing through the sedimentation and filtration mechanism can be increased by pumping the sewage, enabling the sewage to quickly pass through the sedimentation and filtration mechanism to complete the filtration.

[0064] Among them, since the water pipe 102 is closely attached to the inner wall of the sedimentation and filtration mechanism, when the pump 9 works to pump sewage, the permeability of the sewage passing through the sedimentation and filtration mechanism can be increased, enabling the sewage to pass through the sedimentation and filtration layer more quickly and accelerating the overall filtration speed.

[0065] The design of the sealing shell 103 helps to guide the flow direction of the sewage, ensuring that the sewage is evenly distributed and pumped through the covered area. The guide vanes 104 further help to adjust the water flow direction, enabling the sewage to enter the water inlets 105 more smoothly and finally enter the pump through the water pipe 102. Since the sewage is forced to pass through the sedimentation and filtration mechanism instead of flowing naturally, this method not only improves the filtration speed but also increases the chance of contact between the particulate matter and the filtration medium, thereby enhancing the filtration effect.

[0066] Embodiment 4. This embodiment provides a specific implementation of the filter cage assembly 11.

[0067] The sand-settling and filtering mechanism includes a filter cage assembly 11. The filter cage assembly 11 includes a mesh cylinder 111. On one side of the inner wall of the mesh cylinder 111, there is a collar 112. One end of the mesh cylinder 111 is fixedly installed on one side of the support disk 68. The collar 112 is sleeved on the outer surface of the fixed collar 66. On the outer surface of the mesh cylinder 111, two cleaning tooth plates 114 for cleaning the debris between the filter plates 65 are symmetrically arranged. On the outer surface of the mesh cylinder 111, a number of rotating blades 113 are arranged. A number of water filtering holes 115 are opened inside the number of rotating blades 113.

[0068] It should be noted that when extracting sewage through the sealing shell 103, the sewage is first filtered through the rotating blades 113 and the water filtering holes 115 and then filtered through the mesh cylinder 111. The arranged rotating blades 113 are Figure 18 in the shown shape. Because the arranged rotating blades 113 are in an inclined shape, it is convenient for the subsequent brush plate 85 to clean the debris filtered by the rotating blades 113. And the arranged sealing shell 103 is fixed at a position to extract the sewage inside the water inlet tank 2. The arranged mesh cylinder 111 rotates along with the rotation of the support disk 68, which can continuously change the filtering area at the corresponding position of the sealing shell 103. And the arranged cleaning tooth plates 114 also send the debris in the gaps between the filter plates 65 into the interior of the garbage chute plate 5 during rotation.

[0069] Among them, the sewage first undergoes preliminary filtration through the rotating blades 113 with a specific inclined shape and the water filtering holes 115. It can not only effectively intercept larger particulate matters, but also promote the uniform distribution of water flow through the rotation of the rotating blades, reducing the possibility of blockage. After preliminary filtration, the sewage will be further filtered through the mesh cylinder 111. Since the mesh cylinder rotates along with the support disk 68, it can continuously change the filtering area at the corresponding position of the sealing shell 103, thus ensuring the balance and high efficiency of the filtering process.

[0070] The rotating blades are designed to be inclined, which is convenient for the subsequent brush plate 85 to clean the debris accumulated on the rotating blades, simplifies the cleaning process, and reduces the need for manual intervention. As the device operates, the cleaning tooth plates 114 can automatically clean the debris in the gaps between the filter plates 65 and send these debris into the interior of the garbage chute plate 5, not only maintaining the efficient operation state of the filter plates 65, but also avoiding the performance decline caused by debris accumulation.

[0071] Moreover, the design that the mesh cylinder 111 rotates along with the support disk 68 makes the filtering area constantly change. This characteristic helps to prevent the problems of rapid wear or blockage caused by overuse of a certain fixed area, extends the service life of the equipment and maintains a stable treatment efficiency.

[0072] Example Five. This example provides a specific implementation scheme of the filtering component 12.

[0073] The sand sedimentation and filtration mechanism includes a filtration component 12. The filtration component 12 includes a bushing ring 121 and a number of arc plates 122 distributed in a circular array. The bushing ring 121 is installed on the inner walls of the number of arc plates 122. A number of equally spaced mounting grooves 123 are provided on the inner walls of the arc plates 122, and honeycomb filter sheets 126 are provided on the inner walls of the number of mounting grooves 123.

[0074] A cleaning plate 124 for cleaning the debris between the filter sheets 65 is provided on one side of the arc plate 122, and a medicine box 125 is provided on one side of the cleaning plate 124.

[0075] It should be noted that when the sealing shell 103 extracts sewage, the support disk 68 drives the number of arc plates 122 to rotate, and the arc plates 122 will drive the medicine box 125 and the cleaning plate 124 to rotate. As the cleaning plate 124 rotates, it cleans the debris between the filter sheets 65. The medicine box 125 provided can be filled with flocculant. When the sealing shell 103 extracts sewage, the sewage will enter the interior of the sealing shell 103 after being filtered by the honeycomb filter sheet 126. The set sealing shell 103 limits the space area for extracting sewage, enabling the sewage to quickly penetrate into the interior of the sealing shell 103 through the honeycomb filter sheet 126.

[0076] Among them, before the sewage enters the sealing shell 103, it is first filtered by the honeycomb filter sheet 126. The honeycomb structure provides a large surface area, which can effectively intercept fine particles while maintaining a high water flux, enabling the sewage to quickly penetrate into the interior of the sealing shell, improving the overall filtration efficiency. When the support disk 68 rotates, it drives the number of arc plates 122 to rotate together. These arc plates 122 not only play a mechanical support role but also clean the debris between the filter sheets 65 through the connected cleaning plate 124 to prevent blockage and ensure the smooth flow of the water channel. As the arc plates 122 rotate, the cleaning plate 124 continuously moves, effectively removing the debris between the filter sheets 65 and sending it into the garbage chute plate 5, reducing the need for manual cleaning and ensuring the continuous operation of the system.

[0077] The medicine box 125 is filled with flocculant. As the arc plates 122 rotate, the medicine box 125 will also move accordingly. Appropriately adding flocculant helps to agglomerate the fine suspended solids in the sewage, making them easier to be filtered or precipitated. The design of the sealing shell limits the specific space area for extracting sewage, enabling the sewage to more quickly penetrate into the interior of the sealing shell through the honeycomb filter sheet 126, improving the local flow rate and filtration efficiency.

[0078] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
