Description

Technical Field

[0001] This utility model relates to the field of membrane filtration enhancement technology for advanced wastewater treatment, and more particularly to a membrane filtration enhancement device for advanced wastewater treatment. Background Technology

[0002] In the current field of wastewater treatment technology, filtration membranes, as the core separation medium, have been widely used in various water treatment scenarios due to their significant advantages such as high efficiency in retaining pollutants and stable effluent quality. However, a long-standing technical bottleneck lies in the fact that during long-term operation, filtration membranes inevitably become clogged and form a fouling layer due to the adsorption and deposition of suspended solids, colloids, microorganisms, and organic macromolecules on the membrane surface or inside the membrane pores, a phenomenon known as "membrane fouling." This phenomenon directly leads to a continuous decline in membrane flux, resulting in increased operating pressure, significantly increased energy consumption, and a markedly shortened membrane lifespan. While frequent chemical cleaning or physical backwashing can partially restore membrane performance, it not only increases the complexity and cost of operation and maintenance, but the strong chemical agents or mechanical action may also cause irreversible damage to the membrane material itself, and the wastewater generated during the cleaning process may present secondary treatment challenges.

[0003] To address these challenges, membrane enhancement technology has emerged and become a research and application hotspot in recent years. Its core idea lies in actively enhancing the membrane's antifouling ability or optimizing the fluid dynamics of the filtration process through various means, such as physical, chemical, or biological methods, thereby slowing down the fouling process and maintaining long-term stable filtration performance.

[0004] An existing membrane filtration enhancement device for advanced wastewater treatment includes a dosing mechanism, an air extraction component, and a brush nozzle filtration mechanism. This device efficiently filters incoming wastewater. Wastewater is added to the filter cartridge, a settling agent is added, and air is extracted from the cartridge. This causes the dirt in the wastewater to clump together and settle, where it is filtered by the lower filter membrane. A fine brush rotates at a constant speed across the filter membrane surface to prevent the formation of a "filter cake." Combined with the continuous water jet impact from the lower nozzles, this dual protection ensures that the filter membrane consistently purifies wastewater with high efficiency. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a membrane filtration enhancement device for deep wastewater treatment.

[0006] This utility model is achieved by the following technical solution: a membrane filtration enhancement device for deep sewage treatment, including a rotating mechanism, a filtering mechanism and an external mechanism, wherein the lower end of the rotating mechanism is fixedly connected to the filtering mechanism, and the outer side of the filtering mechanism is fixedly connected to the external mechanism.

[0007] The rotating mechanism includes a servo motor, a rotating shaft fixedly connected to the lower end of the servo motor, an adapter fixedly connected to the lower end of the rotating shaft, a motor frame fixedly connected to the outer wall of the servo motor, a controller fixedly connected to the lower end of the adapter, a rotating rod fixedly connected to the lower end of the controller, a fan blade fixedly connected to the outer wall of the rotating rod, a turntable fixedly connected to the lower end of the fan blade, and a fine brush fixedly connected to the lower surface of the turntable.

[0008] The above technical solution involves setting up a dosing mechanism, an air extraction component, and a brush nozzle filtration mechanism to efficiently filter the added wastewater. Wastewater is added into the filter cylinder, a settling agent is added, and air is extracted from the cylinder. This causes the dirt in the wastewater to clump together and sink, where it is filtered by the lower filter membrane. The fine brush rotates and brushes the surface of the filter membrane at a uniform speed to prevent the formation of a "filter cake." Combined with the lower nozzle continuously impacting and spraying water onto the filter membrane, this double protection ensures that the filter membrane always purifies wastewater with high efficiency.

[0009] As a further improvement to the above solution, the filtration mechanism includes a filter membrane, a nozzle is fixedly connected to the lower end of the filter membrane, a water collection chamber is fixedly connected to the lower end of the nozzle, and a water pipe is fixedly connected to the lower end of the water collection chamber.

[0010] The above technical solution involves setting up four nozzles to spray water onto the upper filter membrane from all directions, which works in opposition to the brush mechanism on the upper surface of the filter membrane, ensuring that both ends of the filter membrane are purified and that wastewater is always filtered with high efficiency.

[0011] As a further improvement to the above solution, the external mechanism includes a filter cylinder, with a cylinder cover fixedly connected to the upper end of the filter cylinder, a cylinder bottom fixedly connected to the lower end of the filter cylinder, a cylinder frame fixedly connected to the outer wall of the filter cylinder, a dosing port fixedly connected to the left end of the filter cylinder, an air extraction port fixedly connected to the front end of the filter cylinder, a water inlet fixedly connected to the right end of the filter cylinder, a valve fixedly connected to the outer wall of the water inlet, and a water outlet fixedly connected to the lower surface of the cylinder bottom.

[0012] The above technical solution involves setting up an air extraction port and a chemical dosing port. During the filtration process, chemicals need to be added to improve the chemical purification efficiency of wastewater. Air is extracted from the cylinder to ensure that the chemical reaction of the drugs and bacteria takes place in a vacuum state, thereby increasing the reaction rate.

[0013] As a further improvement to the above solution, the dosing port, water inlet and air extraction port are all located on the outer wall of the filter cylinder and are connected to the inner side of the filter cylinder.

[0014] The above technical solution illustrates the specific locations of the dosing port, water inlet, and air extraction port. Referring to the patent application manual and design drawings will provide a more intuitive understanding.

[0015] As a further improvement to the above solution, the controller includes a valve and a throttle assembly, which applies pressure to the lever to force it to stop rotating when the throttle is turned.

[0016] Through the above technical solution, the controller is designed so that workers can stop or start the rotation of the rotating rod at any time, providing flexibility for filtration.

[0017] As a further improvement to the above solution, the number of fine brushes is set to twelve, with three brushes forming a group, and the four groups are distributed in a circle on the lower surface of the turntable, in contact with the upper surface of the filter membrane.

[0018] The above technical solution uses multiple sets of fine brushes to rotate and cover the entire filter membrane during operation, avoiding dead zones in filtration and thus significantly reducing filtration efficiency.

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

[0020] This invention features a fine brush mechanism. When wastewater is poured in, a servo motor rotates, transmitting power to a rotating rod via an adapter. The rotating rod drives the lower fan blades and turntable to rotate, allowing sedimentation-type chemicals to be added. An air pump draws air from the filter cartridge through the air extraction port, initiating filtration. As filtration time increases, a "filter cake" forms on the filter membrane. The fine brush rotates and brushes this cake, breaking it up and improving filtration efficiency.

[0021] This invention features a nozzle assembly with a water pipe at the bottom for water collection. A large amount of water is concentrated in the collection chamber, and the nozzle injects water, generating a high-pressure water jet impact that strikes the surface of the filter membrane, breaking up the cake layer and further improving filtration efficiency. Combined with the above design, it ensures that the filter membrane will not become clogged and will always maintain high-efficiency filtration. Attached Figure Description

[0033] The filtration mechanism 2 includes a filter membrane 201, a nozzle 202 is fixedly connected to the lower end of the filter membrane 201, a water collection chamber 203 is fixedly connected to the lower end of the nozzle 202, and a water pipe 204 is fixedly connected to the lower end of the water collection chamber 203.

[0034] The external mechanism 3 includes a filter cylinder 301. A cylinder cover 302 is fixedly connected to the upper end of the filter cylinder 301. A cylinder bottom 303 is fixedly connected to the lower end of the filter cylinder 301. A cylinder frame 304 is fixedly connected to the outer wall of the filter cylinder 301. A dosing port 305 is fixedly connected to the left end of the filter cylinder 301. An air extraction port 306 is fixedly connected to the front end of the filter cylinder 301. A water inlet 307 is fixedly connected to the right end of the filter cylinder 301. A valve 308 is fixedly connected to the outer wall of the water inlet 307. A water outlet 309 is fixedly connected to the lower surface of the cylinder bottom 303.

[0035] The dosing port 305, the water inlet 307, and the air extraction port 306 are all located on the outer wall of the filter cylinder 301 and are connected to the inner side of the filter cylinder 301.

[0036] The controller 105 includes a valve and a throttle assembly. Turning the throttle applies pressure to the lever 106 to force it to stop rotating.

[0037] There are twelve fine brushes 109, arranged in groups of three, with four groups distributed in a circle on the lower surface of the turntable 108, in contact with the upper surface of the filter membrane 201.

[0038] The implementation principle of a membrane filtration enhancement device for deep wastewater treatment in this embodiment is as follows: A fine brush 109 mechanism is set up. Wastewater is poured in, and the servo motor 101 rotates. The power is transmitted to the rotating rod 106 through the adapter 103. The rotating rod 106 drives the lower fan blade 107 and the turntable 108 to rotate. Settling agents are added, and the air pump draws air from the filter cartridge 301 through the air extraction port 306 to start filtration. As the filtration time increases, a "filter cake" is generated on the filter membrane 201. The fine brush 109 rotates and brushes it to break up the cake layer, thereby improving the filtration efficiency. A nozzle 202 assembly is set up, and water is connected to the lower water pipe 204. A large amount of water is concentrated in the water collection chamber 203. Water rushes into the nozzle 202, generating a high-pressure water jet impact force to impact the surface of the filter membrane 201, breaking up the cake layer and further improving the filtration efficiency. With the above design, it is ensured that the filter membrane 201 will not become clogged and will always maintain high-efficiency filtration.
