Description

Technical Field

[0001] This utility model relates to the field of membrane equipment technology, and more specifically to a layered curtain-type membrane frame. Background Technology

[0002] A curtain membrane frame is an important support structure used in membrane treatment technology. It has a robust frame structure that can adapt to various complex water quality environments and helps to integrate multiple curtain membrane modules together to form a modular membrane treatment unit, thereby facilitating the installation, maintenance and expansion of the membrane system.

[0003] Traditional curtain-type membrane racks only support the installation of a single curtain-type membrane module, thus failing to provide sufficient wastewater treatment capacity. Furthermore, if the curtain-type membrane module experiences clogging, membrane fiber damage, or sealing issues, the entire rack's filtration function is completely lost. To address this, a common approach is to use multiple membrane racks. However, individual racks can only be arranged horizontally side-by-side; stacking them vertically will affect the aeration efficiency of each curtain-type membrane module. In addition, curtain-type membrane racks with multiple installation positions have emerged, increasing the number of curtain-type membrane modules that can be installed. This paper references Chinese patent publication number CN216737743U, entitled "A Curtain-Type Membrane Rack for MBR". Taking the example of this device, it includes a frame. Multiple sets of placement slots are equidistantly spaced on the top and bottom sides of the frame's inner side. Multiple sets of membrane storage devices are arranged between the equidistant placement slots. Fixed slots communicating with the multiple placement slots are provided on the top and bottom of the front end of the frame. Sliding slots in the front-back direction are provided on the inner walls of the multiple placement slots. Each set of membrane storage devices includes a membrane storage rack and a fixed plate. Sliding plates matching the sliding slots are installed on the top and bottom ends of the membrane storage rack. A frame-shaped stop plate is welded to the right end of the membrane storage rack. Multiple sets of partition slots are equidistantly spaced on the inner wall of the membrane storage rack. Threaded slots are provided at the four corners of the left end of the membrane storage rack. The fixed plate is threadedly connected to the threaded slots by four sets of bolts.

[0004] Although the curtain-type membrane frame described above has multiple membrane storage devices, these devices are still arranged horizontally. This is because a layered design would change the aeration method of the entire membrane frame and affect the aeration effect. Therefore, a horizontal arrangement is adopted. However, this design greatly increases the floor space occupied by the entire membrane frame. To match the membrane frame, the membrane tank area must be expanded, increasing the amount of additional engineering work and production costs. As a result, this type of curtain-type membrane frame cannot be used in environments with limited production space and has obvious limitations on its applicability. Utility Model Content

[0005] In response to the above issues, and to overcome the problems of existing traditional curtain-type membrane frames not being able to be stacked vertically, having a large footprint due to multiple installation positions, requiring an additional membrane tank area to match the frame, resulting in increased engineering work and production costs, and being unsuitable for use in environments with limited production space, the purpose of this utility model is to provide a curtain-type membrane frame with a layered design that occupies less space, has lower production costs, meets production needs in environments with limited land, and does not affect the aeration efficiency of the curtain-type membrane module.

[0006] To achieve the above objectives, the technical solution of this utility model is:

[0007] A layered curtain-type membrane frame includes an end frame, an inner frame, an air intake pipe, an outer support column, an aeration flange, and an aeration pipe. The end frame has two sets, and the inner frame is located between the two end frames and connected to each other through the air intake pipe and the outer support column. The end frame includes a hollow tube and a first connecting rod. The two ends of the hollow tube are connected to and communicate with the air intake pipe. The two ends of the first connecting rod are connected to the outer wall of the air intake pipe and the outer support column. The aeration flange is located on the hollow tube of the top end frame and communicates with the hollow tube. The aeration pipe is arranged in the bottom end frame, and its two ends are connected to the hollow tube and the first connecting rod, respectively, and communicate with the hollow tube.

[0008] Preferably, it also includes a water production flange, a water inlet pipe, and a water production pipe. The number of water production pipes is equal to that of the end frame and the inner frame, and they are correspondingly installed in the end frame and the inner frame. The water production pipe is provided with a water production connector. Each water production pipe is connected through the water inlet pipe and communicates with the water inlet pipe. The water production flange is installed on the top water production pipe and communicates with the water production pipe.

[0009] Preferably, the inner frame includes a second connecting rod, which is located between the air intake pipe and the outer support column, as well as between two adjacent outer support columns.

[0010] Preferably, it also includes a central support rod and an inner support column. The number of central support rods is equal to that of the end frames and the inner frame, and they are correspondingly installed in the end frames and the inner frame. The two ends of the central support rod of each layer are connected by the inner support column.

[0011] Preferably, it also includes corner plates, and the end frames and inner frames are connected to the air intake pipe and the outer support column through the corner plates.

[0012] Preferably, it also includes a hanging plate with hanging holes, and the hanging plate is correspondingly installed on the outer wall of the air intake pipe and the outer support column.

[0013] Compared with the prior art, the advantages of this utility model are:

[0014] (1) The membrane frame of this utility model adopts a layered structure design, which significantly reduces the floor space while allowing the installation of multiple curtain membrane components, ensuring effective adaptation in production environments with limited land. In addition, the membrane frame can be installed by simply increasing the depth of the membrane pool, thus saving on land costs.

[0015] (2) During aeration, the airflow output from the bottom aeration pipe of this utility model membrane frame forms a large number of bubbles in the sewage. When the bubbles rise, they cause water body fluctuations and jointly impact the surface of the membrane fibers of each layer of curtain membrane module, causing the dirt attached to the surface of the membrane fibers to fall off, avoiding membrane fiber blockage, ensuring smooth water production of each layer of curtain membrane module, and solving the problem that the aeration effect is negatively affected by the change of membrane frame structure.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0025] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use.

[0026] like Figures 1 to 6As shown, this utility model relates to a layered curtain-type membrane frame, which includes an end frame 1, an inner frame 2, an air intake pipe 3, an outer support column 4, an aeration flange 5, and an aeration pipe 6. The end frame 1 has two sets, arranged vertically. The inner frame 2 is located between the two end frames 1. The number of inner frame 2 can be configured arbitrarily; different numbers of inner frame 2 determine the number of curtain-type membrane modules that can be installed in this utility model's membrane frame. To improve wastewater treatment efficiency, the number of inner frame 2 can be increased, allowing for the installation of more curtain-type membrane modules. The two end frames 1 and each inner frame 2 are connected by the air intake pipe 3 and the outer support column 6. The support columns 4 are interconnected to maintain a stable upper and lower layered structure. This allows the membrane frame of this invention to significantly reduce the floor space required while allowing the installation of multiple curtain-type membrane modules, ensuring effective adaptation in land-constrained production environments. Furthermore, the membrane frame installation only requires increasing the depth of the membrane tank, thus saving on land costs. In this invention, the air intake pipe 3 is a hollow tube 101, the support columns are solid, and the end frame 1 consists of a hollow tube 101 and a first connecting rod 102. The hollow tube 101 and the first connecting rod 102 are respectively a hollow tube 101 and a solid body. The hollow tube 101... Both ends are connected to the air intake pipe 3 and pass through the interior of the air intake pipe 3. Both ends of the first connecting rod 102 are connected to the air intake pipe 3 and the outer wall of the outer support column 4. The solid structure of the first connecting rod 102 will increase the structural strength of the end frame 1. The aeration flange 5 is set on the hollow pipe 101 of the top end frame 1 and communicates with the hollow pipe 101. The aeration pipe 6 is densely covered with aeration holes, and there are multiple aeration pipes 6. Each aeration pipe 6 is arranged in the bottom end frame 1. Both ends of each aeration pipe 6 are connected to the hollow pipe 101 and the first connecting rod 102 respectively, and communicate with the hollow pipe 101. In this way, the aeration valve flange and the two end frames An aeration channel will be formed between the hollow tube 101, air inlet pipe 3, and aeration pipe 6 of body 1. Compressed air is input from the aeration valve and passes sequentially through the hollow tube 101 of the top end frame 1 and the air inlet pipe 3 to the hollow tube 101 of the bottom end frame 1, and finally outputs through the aeration hole of the aeration pipe 6. The output airflow forms a large number of bubbles in the sewage. When the bubbles rise, they cause water ripples and jointly impact the surface of the membrane fibers of each layer of curtain membrane module, causing the dirt attached to the surface of the membrane fibers to fall off, avoiding membrane fiber blockage, ensuring smooth water production of each layer of curtain membrane module, and solving the problem that the aeration effect is negatively affected by the change of membrane frame structure.

[0027] like Figure 1 and Figure 2As shown, it also includes a water production flange 7, a water inlet pipe 8, and a water production pipe 9. The number of water production pipes 9 is equal to that of the end frame 1 and the inner frame 2, and they are correspondingly set in the end frame 1 and the inner frame 2. The water production pipe 9 is provided with a water production connector 901, which is connected to the curtain membrane module. The filtered water after filtration by each layer of curtain membrane module is diverted through the water production pipe 9. Each water production pipe 9 is connected to the water inlet pipe 8 and communicates with the water inlet pipe 8. The water production flange 7 is set on the top water production pipe 9 and communicates with the water production pipe 9. Except for the filtered water entering the top water production pipe 9, the filtered water entering the other water production pipes 9 will be collected in the water inlet pipe 8 and flow into the corresponding water production pipe 9 of the top end frame 1 through the water inlet pipe 8, and finally discharged at the water production connector 901.

[0028] like Figure 2 As shown, the inner frame 2 includes a second connecting rod 201. There are four sets of the second connecting rod 201. The four sets of second connecting rods 201 are located between the air intake pipe 3 and the outer support column 4, as well as between two adjacent outer support columns 4. The second connecting rods 201 are all solid bodies, which can further improve the structural strength of the entire membrane frame. Due to the increase in the depth of the membrane pool, the possibility of membrane frame deformation under water pressure can be reduced.

[0029] like Figure 1 and Figure 2 As shown, it also includes a central support rod 10 and an inner support column 11. The number of central support rods 10 is equal to that of the end frame 1 and the inner frame 2, and they are placed horizontally in the end frame 1 and the inner frame 2 respectively. The two ends of the central support rod 10 of each layer are connected by the inner support column 11. In this way, each central support rod 10 and the inner support column 11 will also form a frame structure. The central support rod 10 can further reduce the possibility of deformation of the corresponding end frame 1 and inner frame 2 under water pressure, as well as the possibility of collapse and deformation of the entire membrane frame, so that the membrane frame has higher structural strength.

[0030] like Figure 1 and Figure 2 As shown, it also includes a corner plate 12. The end frame 1 and the inner frame 2 are both connected to the air intake pipe 3 and the outer support column 4 through the corner plate 12. Specifically, the corner plate 12 is located at the docking position of the first connecting rod 102 of the end frame 1 with the air intake pipe 3 and the support column, and is located at the docking position of the second connecting rod 201 of the inner frame 2 with the air intake pipe 3 and the support column, thereby providing support for the end frame 1 and the inner frame 2, and further improving the stability and service life of the membrane frame structure.

[0031] like Figure 1 and Figure 2As shown, it also includes a lifting plate 13 with a lifting hole 1301. The lifting plate 13 is correspondingly set on the outer wall of the air intake pipe 3 and the outer support column 4. The lifting hole 1301 is used for the hoisting equipment with hooks to be fastened in, so as to be hoisted into the membrane tank. This can realize the rapid positioning of the membrane frame in the membrane tank and protect the integrity of the membrane frame when it enters the membrane tank, while reducing manpower input and saving labor costs.

[0032] Combination Figures 1 to 6 The membrane frame of this utility model is connected to the lifting hole 1301 of the lifting plate 13 by the hook of the lifting equipment, and the entire membrane frame is lifted into the membrane tank. After installation, sewage treatment can be carried out. The permeate pipes 9 corresponding to the end stubs and the middle frame guide the filtered water after the curtain membrane module to enter the interior. Except for the filtered water entering the top permeate pipe 9, the filtered water entering from the other permeate pipes 9 will be collected in the water inlet pipe 8 and flow into the permeate pipe 9 corresponding to the top end frame 1 through the water inlet pipe 8. Finally, the water production connector 901 is discharged. During aeration, compressed air is input from the aeration valve orifice and passes sequentially through the hollow pipe 101 of the top end frame 1, the air inlet pipe 3, and the hollow pipe 101 of the bottom end frame 1. Finally, it is output from the aeration hole of the aeration pipe 6. The output airflow forms a large number of bubbles in the sewage. When the bubbles rise, they cause water ripples and impact the surface of the membrane fibers of each layer of curtain membrane module, causing the dirt attached to the surface of the membrane fibers to fall off, avoiding membrane fiber blockage, and ensuring smooth water production of each layer of curtain membrane module.

[0033] The embodiments and descriptions above are merely illustrative of the principles and preferred embodiments of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
