Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically a multi-stage wastewater filtration and recovery device. Background Technology

[0002] Wastewater filtration is a key step in the wastewater treatment process, mainly using physical methods to remove suspended solids, particulate matter, and some colloidal substances from wastewater.

[0003] In existing wastewater filtration processes, wastewater is introduced into the inner cavity of a filter cartridge, where it is filtered using a filter screen to remove impurities. However, over time, impurities can clog the filter screen, affecting filtration efficiency. Furthermore, existing filtration devices are not designed for self-cleaning of the screen. Therefore, we propose a multi-stage wastewater filtration and recovery system. Utility Model Content

[0004] The purpose of this invention is to provide a multi-stage wastewater filtration and recycling device that solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage wastewater filtration and recovery device, comprising a cylinder, wherein a cylinder cover is detachably and fixedly connected to the top of the cylinder, and further comprising:

[0006] A first mesh cylinder, with a second mesh cylinder fixedly connected to its inner cavity, and the top of the first mesh cylinder and its cap rotatably connected.

[0007] A rotating shaft is fixedly connected to the middle of the bottom of the first mesh cylinder;

[0008] The blades are multiple, and the multiple blades are evenly fixed to the outer wall of the rotating shaft;

[0009] A sewage pipe is fixedly connected to the lower side of the outer wall of the cylinder.

[0010] By adopting the above technical solution, sewage is introduced into the cylinder through a sewage pipe, and dual multi-stage filtration is performed using the first and second mesh cylinders to improve the filtration effect. When the sewage is introduced into the inner cavity of the cylinder through the sewage pipe, it can directly impact the surface of the blades, thereby driving the blades to rotate, which in turn drives the shaft to rotate, and in turn drives the first and second mesh cylinders to rotate. Under the action of centrifugal force, impurities attached to the surfaces of the first and second mesh cylinders are thrown outward, thereby achieving self-cleaning, reducing clogging, and thus avoiding the situation where clogging affects the filtration efficiency.

[0011] In a preferred embodiment of this utility model, the rotating shaft is a hollow structure, and a guide tube is movably inserted through the inner cavity of the rotating shaft. The guide tube movably inserts through the first mesh cylinder and the second mesh cylinder. The inner cavities of the first mesh cylinder and the second mesh cylinder are respectively provided with a first air distribution pipe and a second air distribution pipe. The first air distribution pipe and the second air distribution pipe are both connected to the guide tube. An air supply pipe is fixedly inserted through the tail end of the cylinder. The inner end of the air supply pipe is connected to the guide tube. Air outlet holes are opened on the outer walls of the first air distribution pipe and the second air distribution pipe.

[0012] By adopting the above technical solution, the conduit is rotatably connected to the inner wall of the rotating shaft through a sealed bearing. In use, gas is introduced into the conduit through the air supply pipe. The gas enters the first and second air distribution pipes and is then discharged through the air outlets on the outer walls of the first and second air distribution pipes. This allows the gas to be blown onto the inner walls of the rotating first and second mesh cylinders, thereby achieving self-cleaning through the back-blowing method and improving the self-cleaning effect.

[0013] In a preferred embodiment of this utility model, the inner diameter of the mesh opening of the first mesh cylinder is larger than the inner diameter of the mesh opening of the second mesh cylinder.

[0014] By adopting the above technical solution, the first mesh cylinder filters out larger impurities, and the second mesh cylinder filters out smaller impurities, thus achieving multi-stage filtration.

[0015] In a preferred embodiment of this utility model, a drain pipe is fixedly connected to the top of the cylinder cover.

[0016] By adopting the above technical solution, the installation of the drainage pipe makes it convenient to export the filtered sewage.

[0017] In a preferred embodiment of this utility model, a sealing ring is fixedly connected to the bottom of the cylinder cover.

[0018] By adopting the above technical solution and setting the sealing ring, the sealing effect can be improved when the cylinder cover and cylinder body are connected.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This application discloses a multi-stage wastewater filtration and recovery device. When wastewater is introduced into the inner cavity of the cylinder through a wastewater pipe, multi-stage filtration is achieved using a first screen cylinder and a second screen cylinder. The wastewater impacts the surface of the blades, thereby driving the rotating shaft to rotate. This, in turn, drives the first and second screen cylinders to rotate. Under the action of centrifugal force, impurities attached to the surfaces of the first and second screen cylinders are thrown outward, thus achieving self-cleaning, reducing clogging, and preventing filtration efficiency from being affected by clogging.

[0021] Gas is introduced into the duct through the trachea, which guides the gas into the first and second air distribution pipes. The gas is then discharged through the air outlets on the outer walls of the first and second air distribution pipes, and blown onto the inner walls of the rotating first and second mesh cylinders. This back-blowing method achieves self-cleaning and improves the self-cleaning effect. Attached Figure Description

[0030] Please see Figure 1-3 This utility model provides a technical solution: a multi-stage wastewater filtration and recycling device, including a cylinder 1, with a detachable and fixedly connected cylinder cover 12 on the top of the cylinder 1, and further including:

[0031] The first net cylinder 2 has a second net cylinder 23 fixedly connected to its inner cavity, and the top of the first net cylinder 2 is rotatably connected to the cylinder cover 12.

[0032] A rotating shaft 21 is fixedly connected to the middle of the bottom of the first mesh cylinder 2;

[0033] There are multiple blades 22, and the multiple blades 22 are evenly fixed to the outer wall of the rotating shaft 21.

[0034] Sewage pipe 11 is fixedly connected to the lower side of the outer wall of cylinder 1;

[0035] It should be understood that in actual use, sewage is introduced into the cylinder 1 through the sewage pipe 11, and the first screen cylinder 2 and the second screen cylinder 23 are used for dual multi-stage filtration to improve the filtration effect. When the sewage pipe 11 introduces sewage into the inner cavity of the cylinder 1, it can directly impact the surface of the blades 22, thereby driving the blades 22 to rotate, which in turn drives the rotating shaft 21 to rotate, and in turn drives the first screen cylinder 2 and the second screen cylinder 23 to rotate. Under the action of centrifugal force, it is beneficial to throw the impurities attached to the surface of the first screen cylinder 2 and the second screen cylinder 23 to the outside, thereby achieving self-cleaning, reducing clogging, and thus avoiding the situation where clogging affects the filtration efficiency.

[0036] Furthermore, the inner diameter of the mesh opening of the first mesh cylinder 2 is larger than that of the mesh opening of the second mesh cylinder 23, thereby enabling the first mesh cylinder 2 to filter larger impurities and the second mesh cylinder 23 to filter smaller impurities, achieving multi-stage filtration.

[0037] Furthermore, a drain pipe 13 is fixedly connected to the top of the cylinder cover 12, which facilitates the discharge of filtered wastewater.

[0038] It is worth mentioning that a sealing ring is fixedly connected to the bottom of the cylinder cover 12. The sealing ring improves the sealing effect when the cylinder cover 12 is connected to the cylinder body 1.

[0039] like Figure 1 and 2 As shown in Figure 3; the rotating shaft 21 is a hollow structure, and the inner cavity of the rotating shaft 21 is movably connected to the guide tube 3. The guide tube 3 movably connects to the first mesh cylinder 2 and the second mesh cylinder 23. The inner cavities of the first mesh cylinder 2 and the second mesh cylinder 23 are respectively provided with the first air distribution pipe 31 and the second air distribution pipe 32. The first air distribution pipe 31 and the second air distribution pipe 32 are both connected to the guide tube 3. The tail end of the cylinder 1 is fixedly connected to the air supply pipe 33. The inner end of the air supply pipe 33 is connected to the guide tube 3. The outer walls of the first air distribution pipe 31 and the second air distribution pipe 32 are both provided with air outlet holes.

[0040] It should be understood that the conduit 3 passes through the rotating shaft 21 and is rotatably connected to the inner wall of the rotating shaft 21 through a sealed bearing. In use, gas is introduced into the conduit 3 through the air supply pipe 33. The gas enters the first air distribution pipe 31 and the second air distribution pipe 32, and then can be discharged through the air outlet holes on the outer wall of the first air distribution pipe 31 and the second air distribution pipe 32, so that it can be blown towards the inner wall of the rotating first mesh cylinder 2 and the second mesh cylinder 23, thereby achieving self-cleaning by using the back-blowing method, which in turn helps to improve the self-cleaning effect.
