Description

Technical Field

[0001] This utility model relates to the field of wastewater filtration technology, and in particular to a filtration device and wastewater treatment equipment. Background Technology

[0002] Wastewater treatment equipment can effectively treat domestic sewage and industrial wastewater, preventing sewage and impurities from flowing directly into water bodies, which is of great significance for improving the ecological environment and promoting economic development. Current wastewater treatment methods require the use of filters to remove particulate matter. However, after a period of use, impurities easily accumulate on the surface of the filters, affecting their filtration efficiency. This necessitates removing the filters from the equipment and manually cleaning them with brushes, which is time-consuming, labor-intensive, and also impacts the overall filtration efficiency. Utility Model Content

[0044] According to a first aspect of the present invention, a filtration device is provided, which includes a housing 10, a filter element 20, a drive assembly, and a flow-deflecting element 30.

[0045] The specific structure of the above-described components of the filtering device according to this embodiment will be described below.

[0046] In this embodiment, as Figure 1 and Figure 2 As shown, a cavity is formed inside the housing 10, and a filter element 20 is disposed inside the housing 10 to divide the cavity into a sewage cavity 100 and a clean water cavity 200. The filter element 20 is formed into a mesh structure with multiple filter holes, so that the filter element 20 can intercept impurities in the sewage as it flows from the sewage cavity 100 to the clean water cavity 200, thus retaining the impurities in the sewage cavity 100. The drive assembly is connected to the filter element 20 to drive the filter element 20 to rotate within the cavity. The rotation of the filter element 20 generates centrifugal force, causing impurities deposited on the surface of the filter element 20 to be removed. The material is thrown towards the sewage chamber 100. The turbulence member 30 is connected to the drive assembly. The turbulence member 30 has a turbulence section 31 disposed in the sewage chamber 100. The drive assembly can drive the turbulence member 30 to rotate, so that a vortex is formed in the chamber. The vortex can wash away the impurities on the surface of the filter element 20. Thus, under the combined action of centrifugal force and vortex impact, the impurities deposited on the surface of the filter element 20 are effectively cleaned. This allows the sewage treatment equipment to be cleaned without disassembling or replacing the filter element 20, which is convenient for maintenance and extends the service life of the equipment.

[0047] It should be noted that in this embodiment, when the filter device is performing normal filtration, the drive component does not drive the filter element 20 and the turbulence-disrupting element 30 to rotate; when it is necessary to clean the surface deposits of the filter element 20, the drive component can be started. Therefore, the start-up cycle of the drive component can be set according to the actual sewage treatment situation to achieve automatic cleaning of the filter element 20.

[0048] Furthermore, in this embodiment, as Figure 1 and Figure 2 As shown, the filter element 20 is formed into a cylindrical structure, and filter holes are provided on the circumferential sidewall of the filter element 20 to form a sewage chamber 100 and a clean water chamber 200 outside and inside the cylinder; the turbulence part 31 is formed into a fan blade structure, preferably the turbulence part 31 is formed into multiple fan blade structures arranged around the rotation axis of the filter element 20, so that the vortex generated by the rotation of the turbulence part 31 can effectively wash away the impurities deposited on the surface of the filter element 20 and improve the cleaning effect.

[0049] In this embodiment, as Figure 1 and Figure 2As shown, the drive assembly includes a drive component 41 and a drive shaft 42. The drive component 41 can be a rotary motor, rotary cylinder, or other device that can provide rotational power. The drive component 41 is disposed outside the housing 10. The drive shaft 42 passes through the housing 10 and is connected to the drive component 41. The drive component 41 is disposed at one end of the drive shaft 42 in the length direction.

[0050] Furthermore, the filter element 20 and the baffle element 30 are sleeved on the drive shaft 42. Preferably, the circumferential sidewall of the drive shaft 42 is formed with an outwardly extending limiting protrusion 43. The end of the baffle element 30 away from the filter element 20 is engaged with the limiting protrusion 43 to achieve axial limiting of the baffle element 30. One end of the filter element 20 on the shaft abuts against the baffle element 30 and the other end abuts against the limiting member 74 sleeved on the drive shaft 42. In this way, the baffle element 30 and the filter element 20 are axially limited to prevent the baffle element 30 and the filter element 20 from moving along the length direction of the drive shaft 42. Specifically, the drive shaft 42 is provided with an annular groove, and one end of the limiting member 74 in the radial direction is embedded in the annular groove.

[0051] In this embodiment, as Figure 2 As shown, the water purification chamber 200 is formed in the space enclosed by the inner wall of the filter element 20 and the outer wall of the drive shaft 42, and the wastewater chamber 100 is formed in the space enclosed by the outer wall of the filter element 20 and the inner wall of the housing 10. The drive shaft 42 has an outlet channel 44 that connects to the water purification chamber 200, so that the water that passes through the filter element 20 and enters the water purification chamber 200 can flow to the outlet channel 44.

[0052] In a preferred embodiment, such as Figure 2 As shown, the water outlet channel 44 is located at the end of the drive shaft 42 away from the drive member 41, forming a cavity inside the end of the drive shaft 42 away from the drive member 41. The cavity is formed as a strip-shaped structure extending along the length direction of the drive shaft 42 and is the main structure of the water outlet channel 44. Multiple openings are provided on the cavity wall, arranged around the rotation axis of the drive shaft 42. The water purification chamber 200 described above and the water outlet 102 shown below are both connected to the cavity via these openings. Two sets of these multiple openings are provided, located at both ends of the cavity's length direction. The axis of each opening extends radially along the drive shaft 42 and leads to the circumferential sidewall of the drive shaft 42, thereby achieving communication between the cavity and the outside of the drive shaft 42.

[0053] Furthermore, in this embodiment, as Figure 1 and Figure 2As shown, the housing 10 has an inlet 101 and an outlet 102. The outlet 102 is located on the side of the housing 10 away from the drive member 41 and is connected to the outlet channel 44. The inlet 101 is connected to the sewage chamber 100, so that the sewage to be treated enters the sewage chamber 100 through the inlet 101. During the process of the sewage passing through the filter element 20, the impurities in the sewage are intercepted, so that the impurities remain in the sewage chamber 100. The sewage after removing the impurities enters the clean water chamber 200 and flows out from the outlet 102 through the outlet channel 44, thereby completing the filtration treatment of sewage.

[0054] In addition, such as Figure 1 and Figure 2 As shown, the housing 10 includes a first housing 11, a second housing 12 and a third housing 13 arranged sequentially along the extension direction of the drive shaft 42. The second housing 12 is formed into a cylindrical structure. The sewage chamber 100 and the clean water chamber 200 are mainly formed within the space enclosed by the second housing 12. The first housing 11 and the third housing 13 block the two ends of the second housing 12 in the axial direction. The first housing 11 and the third housing 13 can be connecting flanges.

[0055] like Figure 1 As shown, the filter device also includes an external mounting plate 80 for fixing the filter device as a whole in the desired position. Optionally, the mounting plate 80 is connected to the third housing 13.

[0056] Furthermore, in this embodiment, as Figure 2 As shown, the filtration device also includes a bearing 73 and a seal 70 sandwiched between the housing 10 and the drive shaft 42; the bearing 73 is used to achieve smooth rotation and reduce friction and wear; the seal 70 can be a rotary seal ring, and the seal 70 is disposed between the cavity and the bearing 73 in the axial direction of the drive shaft 42 to prevent sewage from entering the bearing 73.

[0057] Preferably, the bearing 73 and the seal 70 are both sandwiched between the first housing 11 and the drive shaft 42 and between the third housing 13 and the drive shaft 42, and multiple seals 70 are provided, with multiple seals 70 arranged at intervals between the cavity and the bearing 73.

[0058] Furthermore, such as Figure 2 As shown, the filter device also includes an exhaust valve 76 and an oil nozzle 75. Lubrication channels are provided on the first housing 11 and the third housing 13. The lubrication channels are connected to the bearing 73 and / or connected to the two adjacent seals 70 in the axial position. The exhaust valve 76 and the oil nozzle 75 are installed on the oil channel. The exhaust valve 76 and the oil nozzle 75 are existing components, and their specific structure and working principle will not be described in detail here.

[0059] In this embodiment, as Figure 2 and Figure 3 As shown, a drain port 103 is provided on the housing 10; the filter device also includes a drain assembly connected to the housing 10 for discharging impurities in the sewage chamber 100 to the outside of the housing 10. Preferably, the drain port 103 is located at the bottom of the housing 10, and the inlet 101 is located at the top of the housing 10, which helps impurities to accumulate at the bottom of the housing 10 under the action of gravity, so that they can be discharged outside the housing 10 when the drain assembly is opened.

[0060] Specifically, in this embodiment, such as Figure 2 and Figure 3 As shown, the sewage discharge assembly includes a valve housing 51 and a valve core 52. The valve housing 51 has a valve cavity inside, which includes a first channel 501 and a second channel 502 that are interconnected. The first channel 501 and the second channel 502 are spaced apart. An inlet 511 and an outlet 512 are provided on the outer wall of the valve housing 51. The inlet 511 is connected to the sewage outlet 103 and the first channel 501, respectively. The outlet 512 is connected to the second channel 502, allowing sewage carrying impurities that needs to be discharged from outside the housing 10 to pass through the sewage outlet 103 and the inlet 512. The inlet 511 enters the valve housing 51, and then flows out of the valve housing 51 in sequence through the first channel 501, the second channel 502, and the outlet 512. The valve core 52 is disposed inside the valve housing 51 and can move inside the valve housing 51, thereby disconnecting or connecting the first channel 501 and the second channel 502. When the first channel 501 and the second channel 502 are connected, impurities are discharged outside the housing 10. When the first channel 501 and the second channel 502 are disconnected, sewage carrying impurities cannot enter the second channel 502 and thus cannot flow out of the valve housing 51.

[0061] In the first preferred embodiment, such as Figure 2 and Figure 3 As shown, the valve core 52 is slidably connected to the valve housing 51. The end of the valve housing 51 is formed as a drive end 513 connected to the fluid drive module. The fluid drive module can be a hydraulic module. The drive end 513 is located at one end of the valve core 52 in the direction of movement. The drive end 513 is preferably a hydraulic input port, which is connected to a hydraulic motor. In this way, the movement of the valve core 52 can be controlled by pressing in hydraulic oil. The first channel 501 and the second channel 502 are arranged at intervals in the direction of movement of the valve core 52. The circumferential sidewall of the valve core 52 has a protruding sealing part 521. The sealing part 521 is formed as an annular structure and can abut against the cavity wall of the valve cavity. Thus, when the sealing part 521 abuts against the cavity wall, the first channel 501 and the second channel 502 are disconnected. When the sealing part 521 is separated from the valve cavity, the first channel 501 and the second channel 502 are connected. Then, the valve core 52 is slidably controlled by the drive end 513 to control the connection or disconnection of the first channel 501 and the second channel 502. It has the advantages of convenient operation and sensitive control.

[0062] Furthermore, such as Figure 2 As shown, the sewage discharge assembly also includes a first elastic element 53, which is a spring. It is located at the other end of the valve core 52 in the direction of movement. That is, the first elastic element 53 and the drive end 513 are respectively located at the two ends of the valve core 52 in the direction of movement. When the drive end 513 presses in hydraulic oil, it can drive the valve core 52 to move away from the drive end 513, so as to squeeze the first elastic element 53, thereby opening the connection between the first channel 501 and the second channel 502. After the impurities are discharged from the housing 10, the hydraulic motor described above is turned off. At this time, the first elastic element 53 is reset to push the valve core 52 to move towards the drive end 513 until the sealing part 521 is firmly abutted against the cavity wall, ensuring that the first channel 501 and the second channel 502 are disconnected.

[0063] In a second alternative embodiment, the valve core is rotatably connected to the valve housing to enable the connection or disconnection of the first channel and the second channel.

[0064] In a preferred embodiment, such as Figure 3 As shown, the sewage discharge assembly also includes a connector 61, a sliding member 62, and a second elastic member 63. Specifically, the connector 61 is installed on the outlet 512. The connector 61 can be formed as a cap on the outer wall of the valve housing 51. A flow guiding cavity is formed inside the connector 61. A discharge port 611 communicating with the flow guiding cavity is opened on the side wall of the connector 61. The discharge port 611 is located in the circumferential direction of the connector 61. The sliding member 62 is disposed in the flow guiding cavity. A limiting part 622 that can abut against the outer wall of the valve housing 51 is formed on the sliding member 62, so that the valve housing 51 can limit the sliding of the sliding member 62. Sewage entering the second channel 502 can squeeze the sliding member 62, causing it to move towards the connector 61, thereby driving the limiting part 622 to separate from the valve housing 51, so that the outlet 512 connects the second channel 502 and the discharge port 611.

[0065] The second elastic element 63 is disposed between the connecting member 61 and the sliding member 62. The second elastic element 63 can be a compression spring. When the valve core 52 moves to the point where the first channel 501 and the second channel 502 are connected, sewage carrying impurities enters the second channel 502 and drives the sliding member 62 to move, causing the limiting part 622 to separate from the valve shell 51. This causes compression on the second elastic element 63. When the valve core 52 moves to the point where the first channel 501 and the second channel 502 are disconnected, the second elastic element 63 resets to drive the sliding member 62 to move away from the connecting member 61, causing the limiting part 622 to abut against the valve shell 51. This seals the outlet 512 and prevents external impurities from entering the valve shell 51 and causing pollution or blockage.

[0066] In a preferred embodiment, such as Figure 3As shown, a recessed locking groove 623 is formed at one end of the slider 62 near the connector 61. At least part of the second elastic member 63 is embedded in the locking groove 623, thus limiting the second elastic member 63 circumferentially and ensuring that the second elastic member 63 can extend and retract along its axis, thereby ensuring that the sliding trajectory of the slider 62 can effectively open or block the outlet 512.

[0067] In other alternative embodiments, the outlet 512 is directly connected to the sewage pipe. Specifically, the end of the outlet 512 facing the outside of the valve housing 51 is provided with a thread for connection to the sewage pipe.

[0068] In this embodiment, the extension and retraction direction of the first elastic member 53 is perpendicular to the extension and retraction direction of the second elastic member 63.

[0069] According to the filtration device of this utility model, a cavity is formed inside the housing; a filter element is disposed inside the housing to divide the cavity into a sewage cavity and a clean water cavity, thereby filtering impurities in the sewage; a drive assembly is connected to the filter element and the turbulence-disrupting element respectively to drive the filter element and the turbulence-disrupting element to rotate within the cavity; the rotation of the filter element generates centrifugal force, causing impurities deposited on the surface of the filter element to be thrown outwards; the turbulence-disrupting element has a turbulence-disrupting part disposed in the sewage cavity; the drive assembly can drive the turbulence-disrupting element to rotate, thereby forming a vortex in the cavity to wash away impurities on the surface of the filter element, thereby effectively cleaning the impurities deposited on the surface of the filter element, thus enabling cleaning without disassembling or replacing the filter element, facilitating maintenance and extending the service life of the filter element.

[0070] The second aspect of this utility model provides a wastewater treatment device, including the filtration device as described above, which can clean impurities deposited on the surface of the filter element without disassembling or replacing the filter element, thereby improving the wastewater treatment efficiency of the wastewater treatment device and extending the service life of the device.
