Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a membrane separation device for advanced treatment. Background Technology

[0002] In recent years, due to the development of membrane science and technology and the upgrading of water treatment technology, membrane separation technology and membrane separation equipment using membrane separation technology have been increasingly applied in the field of water treatment. According to the announcement number CN104437092B, a membrane separation device for water treatment is disclosed.

[0003] Currently, wastewater filtration often relies on natural water flow, which is inefficient. Therefore, we propose a membrane separation device for advanced treatment to address the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies that rely on natural water flow for wastewater filtration, which is often inefficient. This invention proposes a membrane separation device for advanced wastewater treatment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A membrane separation device for advanced processing includes a mounting box, a drain pipe fixedly installed on the inner wall of one side of the bottom of the mounting box, and the bottom end of the drain pipe extending to the bottom of the mounting box. The separation device also includes:

[0007] The support mechanism is installed inside the mounting box;

[0008] Multiple filtration units are installed on and through the support structure, and are used to filter wastewater.

[0009] The power mechanism includes a drive motor fixedly mounted on the top of one side of the mounting box. The output shaft of the drive motor extends into the mounting box and is fixedly mounted with a drive bevel gear. A bevel gear ring is connected to the support mechanism, and the drive bevel gear meshes with the bevel gear ring.

[0010] In one possible design, the support mechanism includes a support ring fixedly installed inside the mounting box. The top of the support ring has multiple slots at equal intervals. It also includes a retaining ring. The bottom of the retaining ring has multiple retaining plates fixedly installed at equal intervals. The bottom of the retaining plates extends into the corresponding slots and engages with the slots. The top of the retaining ring is rotatably connected to a conical cover. The conical cover has multiple placement holes at equal intervals. The filter mechanism passes through the placement holes and contacts the inner wall of the placement holes. A beveled ring is fixedly installed at the bottom of the conical cover.

[0011] In one possible design, the filtration mechanism includes a mesh barrel that passes through the corresponding placement hole and is mounted on a conical hood, with an installation ring fitted inside the mesh barrel and a biofilm hood fixedly installed at the bottom of the installation ring.

[0012] In one possible design, a filter screen is fitted inside the mounting ring, and a handle is fixedly installed on the top of the filter screen, with the top of the handle extending above the filter barrel.

[0013] In one possible design, the separation device further includes a support pipe that penetrates the inner wall of the bottom of the conical shroud and is fixedly connected to the inner wall of the bottom of the conical shroud. An air blowing pipe is fixedly installed at the bottom end of the support pipe, and a bend pipe is rotatably connected to the top end of the support pipe. One end of the bend pipe extends to the outside of the mounting box and is fitted with an air extraction component. The air extraction component is installed on the other side of the mounting box, and a transmission component is penetrated and connected to the inner wall of the other side of the mounting box. One side of the transmission component is engaged with a bevel gear ring, and the other side of the transmission component is connected to the air extraction component.

[0014] In one possible design, the air extraction assembly includes a mounting cover fixedly mounted on the top of the other side of the mounting box. A retaining ring is provided on the top inner wall of the mounting cover, the top of the retaining ring extends above the mounting cover, one end of the bent tube extends into the retaining ring and engages with the inner wall of the retaining ring, and a blade shaft is rotatably connected inside the mounting cover. The bottom end of the blade shaft extends below the mounting cover and is connected to a transmission assembly.

[0015] In one possible design, the transmission assembly includes a transmission shaft that passes through and is rotatably connected to the inner wall of the other side of the mounting box. A connecting bevel gear is fixedly mounted on one end of the transmission shaft, and the connecting bevel gear meshes with a bevel gear ring. A transmission bevel gear is fixedly mounted on the other end of the transmission shaft. A driven bevel gear is fixedly mounted on the bottom end of the blade shaft, and the transmission bevel gear meshes with the driven bevel gear.

[0016] In this application, the mesh buckets are first placed on the conical hood, and then the mounting rings are placed inside the mesh buckets. This allows the biofilm hood to be positioned inside the mesh buckets. Wastewater can then be diverted into the conical hood and flow into multiple mesh buckets. Because filter plates are placed inside the mounting rings, the wastewater can be pre-filtered before the biofilm hood performs fine filtration. This pre-filters large particles of impurities in the wastewater onto the filter plates, reducing the filtration burden on the biofilm hood. After the wastewater passes through the filter plates, it can be filtered by the biofilm hood. Simultaneously, the drive motor is started, driving the active bevel gear to rotate. Under the meshing transmission action with the bevel gear ring, the conical hood rotates, causing multiple mesh buckets to move in a ring motion, thus enabling the biofilm hood to move in a ring motion. The system is designed to facilitate centrifugal motion, increasing the rate at which wastewater passes through the biofilm hood. The mesh support prevents the biofilm hood from being breached by the centrifugal force. Simultaneously, the rotating bevel gears, in conjunction with the meshing bevel gears, drive the transmission shaft. This meshing of the drive and driven bevel gears then rotates the blade shaft, providing a stable driving force. The rotating blade shaft generates suction, drawing in external gas. This gas is then transported through a bend and support pipe to the aeration pipe, effectively aerating the filtered water.

[0017] Beneficial effects: In this utility model, the membrane separation device for deep treatment can use a support mechanism to lock the plate with the corresponding slot to position the lap ring, thereby enabling the conical cover to rotate and be supported. After the bevel gear ring receives the driving force of the active bevel gear, it can drive the conical cover to rotate, thereby driving multiple filtration mechanisms to move. Thus, when filtering sewage, the sewage can undergo centrifugal motion and quickly pass through the filtration mechanism, thereby improving the filtration efficiency of sewage.

[0018] In this utility model, the membrane separation device for deep treatment, through the filtration mechanism, can place the mesh bucket on the conical cover and the mounting ring inside the mesh bucket, thereby placing the biofilm cover inside the mesh bucket. When the mesh bucket moves in a ring with the conical cover, it can drive the biofilm cover to move in a ring. Therefore, after the sewage enters the biofilm cover, it can cause the sewage to undergo centrifugal motion, thereby increasing the rate at which the sewage passes through the biofilm cover. At the same time, the mesh bucket can support the biofilm cover, thereby preventing the centrifugal force of the sewage from breaking through the biofilm cover.

[0019] In this utility model, the membrane separation device for deep treatment can be driven by a power mechanism to rotate the active bevel gear driven by the start-up drive motor. At this time, under the meshing transmission action with the bevel gear ring, the conical cover can be rotated, which can drive multiple mesh barrels to perform circular motion, so that the biofilm cover can perform circular motion. Therefore, after the sewage enters the biofilm cover, the sewage can be centrifuged, thereby increasing the rate at which the sewage passes through the biofilm cover.

[0020] This invention, when filtering wastewater, can drive multiple biofilm hoods to move in a ring by driving a motor, thereby causing the wastewater to undergo centrifugal motion inside the biofilm hoods, thus improving the filtration efficiency. At the same time, it can also aerate the filtered wastewater, so the overall equipment has good practicality. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1: Refer to Figure 1-5 A separation device, firstly, constructs an installation box 1 as the main structure, and fixes a drain pipe 23 on the inner wall of one side of its bottom. The bottom end of the drain pipe 23 extends to the bottom of the installation box 1 for discharging treated sewage.

[0029] A support mechanism is installed inside the mounting box 1. The support mechanism consists of a support ring 2 fixedly installed inside the mounting box 1, with multiple slots evenly spaced on the top of the support ring 2. Additionally, a retaining ring 3 is included, with multiple retaining plates 4 fixedly installed at equal intervals on its bottom. The bottom of the retaining plates 4 extends into the corresponding slots and engages with them, thereby positioning the retaining ring 3. The top of the retaining ring 3 is rotatably connected to a conical cover 5, with multiple placement holes evenly spaced on the conical cover 5.

[0030] Next, multiple filtration units are installed. Each filtration unit includes a mesh barrel 6 that passes through a corresponding placement hole and is mounted on a conical shroud 5. An installation ring 7 is fitted inside the mesh barrel 6, and a biofilm shroud 8 is fixedly mounted at the bottom of the installation ring 7. After the mesh barrel 6 is placed on the conical shroud 5, the installation ring 7 is placed inside the mesh barrel 6, thereby placing the biofilm shroud 8 inside the mesh barrel 6. Furthermore, a filter screen 9 is also fitted inside the installation ring 7, and a handle 10 is fixedly mounted on the top of the filter screen 9. The top of the handle 10 extends above the mesh barrel 6 for easy removal and replacement of the filter screen 9.

[0031] Next, the power mechanism is installed. The power mechanism includes a drive motor 16 fixedly mounted on the top side of the mounting box 1, whose output shaft extends into the mounting box 1 and is fixedly mounted with a drive bevel gear 17. A bevel ring 18 is fixedly mounted on the bottom of the conical cover 5 on the support mechanism, and the drive bevel gear 17 meshes with the bevel ring 18. When the drive motor 16 is started, the drive bevel gear 17 drives the bevel ring 18 and the conical cover 5 to rotate, thereby driving the movement of multiple filtration mechanisms.

[0032] To further improve the performance of the equipment, an aeration device is also installed. This device includes a support pipe 11 that penetrates the inner wall of the bottom of the conical hood 5 and is fixedly connected to it. An air blowing pipe 12 is fixedly installed at the bottom end of the support pipe 11. A bent pipe 13 is rotatably connected to the top end of the support pipe 11. One end of the bent pipe 13 extends to the outside of the mounting box 1 and is fitted with an air extraction assembly. The air extraction assembly is installed on the other side of the mounting box 1 and consists of a mounting cover 14 fixedly installed on the top of the other side of the mounting box 1. A retaining ring is provided on the inner wall of the top of the mounting cover 14, and one end of the bent pipe 13 extends into the retaining ring and is fitted with the inner wall of the retaining ring. A blade shaft 15 is rotatably connected inside the mounting cover 14.

[0033] This application can be used in the field of wastewater treatment technology, or in other fields applicable to this application.

[0034] Example 2: Reference Figure 4An improvement upon Embodiment 1: A membrane separation device for advanced treatment, applied in the field of wastewater treatment technology, includes a transmission assembly for connecting the power mechanism and the aeration device. This assembly includes a drive shaft 19 that penetrates the inner wall of the other side of the mounting box 1 and is rotatably connected to it. One end of the drive shaft 19 is fixedly mounted with a connecting bevel gear 20, which meshes with a bevel gear ring 18. The other end of the drive shaft 19 is fixedly mounted with a drive bevel gear 21, and the bottom end of the blade shaft 15 is fixedly mounted with a driven bevel gear 22, which meshes with the drive bevel gear 21.

[0035] During operation, the drive motor 16 starts, driving the bevel gear 17 to rotate the bevel ring 18 and the conical cover 5, which in turn drives multiple filtration mechanisms to perform circular motion. Wastewater enters from above the conical cover 5, undergoes coarse filtration through the filter screen 9, and then enters the biofilm cover 8 for fine filtration. Simultaneously, the rotation of the bevel ring 18 drives the drive shaft 19 to rotate via the connecting bevel gear 20, which in turn drives the blade shaft 15 to rotate through the meshing of the drive bevel gear 21 and the driven bevel gear 22. The rotation of the blade shaft 15 generates suction, drawing external air into the mounting cover 14, which is then transported through the bend pipe 13 and the support pipe 11 to the air blowing pipe 12 to aerate the filtered water.

[0036] However, as is well known to those skilled in the art, the working principle and wiring method of the drive motor 16 are commonplace and are all conventional methods or common knowledge. They will not be elaborated here. Those skilled in the art can make any selections according to their needs or convenience.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
