Description

Technical Field

[0001] This utility model relates to the field of water resource treatment technology, and in particular to a smart pre-coated membrane precision filtration mechanism. Background Technology

[0002] In fields such as water resource recycling, food processing and purification, pharmaceutical preparation, and advanced industrial wastewater treatment, precision filtration technology is a core element in ensuring fluid purity and safety. As society's requirements for water quality precision (such as suspended solids removal rate and microbial control), filtration efficiency, and environmental friendliness continue to increase, traditional precision filtration technology is gradually revealing its insufficient adaptability, making it difficult to meet the comprehensive needs of "high precision, low energy consumption, no residue, and high stability."

[0003] Existing precision filtration technologies mainly include three categories: membrane filtration (such as ultrafiltration and microfiltration), multi-stage quartz sand filtration, and traditional diatomaceous earth filtration. Among them, membrane filtration technology can achieve high-precision filtration of 0.1-10μm, but the membrane modules are prone to clogging due to the adhesion of suspended matter in the fluid, requiring frequent chemical cleaning or replacement. This not only increases operation and maintenance costs (the cost of a single membrane replacement can reach 30% to 50% of the total equipment cost), but may also contaminate the filtered fluid due to residual cleaning agents, making it particularly unsuitable for scenarios with strict hygiene requirements, such as drinking water and dairy products. Quartz sand filtration technology has a lower cost, but the filtration accuracy can only reach 10-50μm, requiring subsequent multi-stage filtration units to meet precision requirements. This results in a large system footprint, complex process, and high regeneration difficulty after the quartz sand filter media becomes saturated, which can easily generate solid waste pollution.

[0004] Diatomaceous earth, as a natural siliceous mineral, has a porous structure (specific surface area can reach 50-600 m²). 2With its strong adsorption and chemical stability, diatomaceous earth has long been used in precision filtration. Traditional diatomaceous earth filtration devices mostly employ intermittent filtration, directly mixing diatomaceous earth into the fluid to be filtered to form a filter layer. While this can achieve a filtration accuracy of 0.5-1μm, it suffers from three major drawbacks: First, low filter media utilization – traditional devices lack a circulation adjustment mechanism, and the diatomaceous earth only contacts the fluid once, failing to fully utilize its synergistic adsorption and filtration effects. Furthermore, the filter layer is prone to localized clogging, leading to a sharp drop in overall filtration efficiency, requiring frequent shutdowns to replace the filter media, resulting in short maintenance cycles. Second, poor compatibility with pre-coated membrane technology – existing pre-coated membrane filters mostly use single resins or quartz. The sand coating does not take advantage of the porous nature of diatomaceous earth, and the coating thickness and distribution are difficult to dynamically adjust to adapt to different fluid conditions (such as fluctuations in suspended solids concentration), resulting in unstable filtration accuracy. Thirdly, the disinfection process is disconnected—after traditional diatomaceous earth filtration, the fluid needs to be connected to an additional chemical disinfection unit (such as chlorine disinfection or ozone disinfection), which not only increases the complexity of the system but may also produce disinfection byproducts (such as chloroform and bromate). If the disinfection step is omitted, microorganisms (such as Escherichia coli and Legionella) are prone to grow, especially failing to meet the hygiene standards for drinking water, medical water, and other scenarios.

[0005] Perlite, another type of natural siliceous porous mineral, is characterized by its low density (bulk density of only 80–150 kg / m³). 3 With its high porosity (70%–90%) and good chemical inertness, perlite has been gradually applied in the field of precision filtration in recent years, but its current applications still have obvious limitations: the porous structure of perlite is mainly composed of interconnected pores, and the specific surface area can reach 30–300 m². 2 With a filtration precision between quartz sand and diatomaceous earth (approximately 0.1-5μm), it can effectively remove fine suspended solids and some colloids from fluids; its density is much lower than that of diatomaceous earth, and the filter layer has good air permeability, which can reduce fluid flow resistance and reduce energy consumption; at the same time, the raw material cost is only 60% to 80% of that of diatomaceous earth, and its operation and maintenance economy is better than that of membrane filtration and diatomaceous earth filtration.

[0006] In addition, existing precision filtration systems use chemical reagents such as acids, alkalis, oxidants, or chelating agents to dissolve or decompose contaminants on and inside the filter membrane. While this method can improve impurity removal, it has significant drawbacks: firstly, chemical reagents easily corrode the microporous structure of the filter membrane, damaging the integrity of the pre-coated membrane and leading to a decrease in filtration accuracy; secondly, residual chemical reagents can contaminate subsequent fluids (especially in the food and pharmaceutical industries), requiring additional water washing processes, which not only prolongs the regeneration cycle but also increases water consumption and treatment costs. While the synergistic effect of gas agitation and water rinsing enhances impurity removal, this technology has poor adaptability to pre-coated membranes. The pre-coated membrane itself has a loose, porous structure, and high-pressure gas can easily cause the pre-coated membrane layer to detach and break, exacerbating membrane wear; simultaneously, uneven distribution of gas and water flow can lead to incomplete local regeneration of the filter membrane, creating "dead-angle blockages," resulting in flux distribution differences of over 30% after regeneration.

[0007] In summary, the current precision filtration field urgently needs a device that enables controllable, multi-cycle water treatment within a system and achieves high efficiency in the membrane regeneration process during water treatment. Utility Model Content

[0031] like Figures 1 to 5As shown in the figure, an embodiment of the present invention provides a smart pre-coated membrane precision filtration mechanism, including a filtration module 100, a circulation regulating pipe 200, and a disinfection module 300. The filtration module 100 is provided with a filtration device 110, a first inlet 120, and a first outlet 130. The circulation regulating pipe 200 is connected to the filtration device 110 through the first inlet 120 and the first outlet 130. The circulation regulating pipe 200 is provided with an inlet end 240 and an outlet end 250. The circulation regulating pipe 200 is used to circulate the fluid, so that the fluid circulates within the filtration module 100 and the circulation regulating pipe 200. The disinfection module 300 is disposed on the circulation regulating pipe 200, and the disinfection module 300 disinfects the fluid within the circulation regulating pipe 200.

[0032] In this embodiment, the filtration mechanism is mainly used for filtering and disinfecting water resources, purifying the water for normal use. During the water purification process, an external water source is connected via the inlet 240 of the circulation regulating pipe 200. The external water source enters the circulation regulating pipe 200 through the first inlet 120, causing the water to flow through the circulation regulating pipe 200. The water then flows into the filter device 110 within the filter module 100 through the first inlet 120. The filter device 110 performs deep filtration of the water, and the filtered water is discharged through the first outlet 130. The water enters the circulation regulating pipe 200. When the filtered water meets a certain cleanliness requirement, it can be discharged directly through the outlet 250 to achieve water purification. When the filtered water does not meet the certain cleanliness requirement, the water is circulated through the circulation regulating pipe 200, so that the filtered water enters the filter device 110 again through the first inlet 120 for further filtration. When the water has been circulated and filtered to a certain extent, it can be discharged through the outlet 250 to achieve the water filtration and purification process.

[0033] In the above structure, the filter device 110 in the filter module 100 mainly contains a filter medium. In this embodiment, the filter medium is a diatomaceous earth pre-coated membrane or a perlite pre-coated membrane. The diatomaceous earth or perlite pre-coated membrane has a unique microporous structure and a large specific surface area, effectively intercepting tiny particles, suspended solids, and some colloidal substances in the water. When water flows through the filter device 110, these pre-coated membranes act like a fine sieve, trapping impurities on the surface, allowing clean water to pass through, thus achieving deep purification of the water. Simultaneously, this pre-coated membrane also has a certain adsorption capacity, capable of adsorbing some organic matter and odorous substances in the water, further improving the purity and taste of the water. In practical applications, the thickness and composition of the pre-coated membrane can be flexibly adjusted according to different water quality conditions and filtration requirements to achieve the best filtration effect.

[0034] Preferably, the filter medium can also be activated carbon or ion exchange resin.

[0035] Preferably, in this embodiment of the application, in order to facilitate observation of the water purification effect, an observation window is provided on the circulation regulating pipe 200. The observation window is set as part of the structure of the circulation regulating pipe 200, specifically located on the circulation regulating pipe 200 corresponding to the outlet of the filter device 110. The observation window is made of transparent material, preferably acrylic material, so as to more clearly observe the water purification effect and thus facilitate control of whether the purified water is discharged from the outlet 250.

[0036] Meanwhile, to improve the water purification effect in this application, the disinfection module 300 in this embodiment can effectively disinfect the water. Specifically, the disinfection module 300 employs an ultraviolet disinfection device to achieve sterilization and disinfection. In practical applications, the ultraviolet disinfection device can be installed at an appropriate location in the circulation regulating pipe 200 to ensure that the water receives sufficient ultraviolet radiation during circulation, achieving efficient disinfection.

[0037] Furthermore, to ensure the safe and stable operation of the filtration mechanism, various safety protection measures are also provided in this embodiment. For example, pressure sensors and temperature sensors are installed on the filtration device 110 and the circulation regulating pipe 200 to monitor the pressure and temperature changes inside the equipment in real time. When the pressure or temperature exceeds the set threshold, the system will automatically alarm and take corresponding protective measures, such as stopping the equipment operation and discharging water with excessive pressure or temperature, to prevent equipment damage or safety accidents.

[0038] In the above structure, the circulation regulating pipe 200 includes a first circulation pipe 210, a second circulation pipe 220, and a filter media device 230. The first circulation pipe 210 connects the first inlet 120 and the inlet end 240. A driving device 211 is provided on the first circulation pipe 210. The driving device 211 drives the fluid from the inlet end 240 through the first circulation pipe 210 and the first inlet 120 into the filter module 100. The second circulation pipe 220 connects to the first circulation pipe 210 and the first outlet 130. The filter media device 230 stores filter media and connects to the first circulation pipe 210 and the first inlet 120. The driving device 211 is used to drive the fluid to push the filter media into the filter device 110.

[0039] To achieve the circulation process and filtration effect of the water body, the circulation regulating pipe 200 is provided with a first circulation pipe 210. The first circulation pipe 210 is connected to the inlet end 240 and the first inlet 120, so that external water can directly enter the filter device 110 through the first circulation pipe 210 and the first inlet 120. A driver is provided to provide power support for the water body in the first circulation pipe 210, which can drive the continuous flow of the water body.

[0040] To achieve the aforementioned circulation effect, a second circulation pipe 220 is installed on the first circulation pipe 210 and connected to the first outlet 130. The second circulation pipe 220 is also connected to the first circulation pipe 210, so that the water in the filter device 110 enters the first circulation pipe 210 through the second circulation pipe 220, and the filtered water re-enters the filter device 110 through the first circulation pipe 210, thus realizing the basic circulation process.

[0041] The second circulation pipe 220 is connected to the first circulation pipe 210 at a position between the water inlet 240 and the drive device 211.

[0042] However, in this embodiment, to enhance the filtration effect of the filter device 110, a filter media device 230 is required. The filter media device 230 stores diatomaceous earth material and has a second inlet and a second outlet. In this embodiment, the second inlet is connected to the first circulation pipe 210, and the connection point is located on the first circulation pipe 210 between the drive device 211 and the first inlet 120. The second outlet is connected to the first inlet 120, so that when the drive device 211 is started, the water in the first circulation pipe 210... The water can enter the filter media device 230 through the second inlet and the first inlet 120. The transport of the water carries the filter media in the filter media device 230 into the filter device 110. Since there is a filter rod in the filter device 110, when the water enters the filter device 110, the filter media carried by the water will adhere to the outside of the filter rod to form a diatomaceous earth membrane. The water passes through the filter membrane into the hollow filter rod and is discharged through the first outlet 130. Impurities in the water will adhere to the diatomaceous earth membrane, which facilitates the filtration of the water. The membrane can effectively filter and purify the water.

[0043] In this embodiment, the second outlet of the filter media device 230 can be connected to the position between the drive device 211 and the inlet 240 on the first circulation pipe 210. In order to ensure the formation of the filter membrane, a first regulating valve 214 is provided at the inlet 240. When the valve is closed, an internal circulation process is formed. After multiple cycles, the diatomaceous earth membrane can be effectively formed.

[0044] Preferably, in this embodiment of the application, the first water inlet 120 of the filter media device 230 can be directly connected to an external water pump for effective transport of the filter media.

[0045] In this embodiment, the first circulation pipe 210 includes an inlet pipe 212 and a first flow pipe 213. One end of the inlet pipe 212 is provided with the inlet end 240, and the other end of the inlet pipe 212 is connected to the driving device 211. One end of the first flow pipe 213 is connected to the driving device 211, and the other end of the first flow pipe 213 is connected to the filter module 100 through the first inlet port 120. The second circulation pipe 220 is connected to the inlet pipe 212, and a first regulating valve 214 is provided at the inlet end 240 position on the inlet pipe 212.

[0046] The above structure effectively breaks down the first circulation pipe 210 to provide a clear structural description of the first circulation pipe 210, specifically as follows: Figure 3As shown, the inlet pipe 212 is connected to the inlet end 240 and is responsible for introducing external water into the entire filtration system. The first regulating valve 214 installed on the inlet pipe 212 can control the on / off state and flow rate of the water. When the first regulating valve 214 is closed, the water flow is restricted to circulate within the first circulation pipe 210 and the second circulation pipe 220, which facilitates the adhesion of diatomaceous earth to the filter rods in the filter device 110 to form an effective filter membrane.

[0047] The first flow pipe 213 is directly connected to the drive device 211. The drive device 211 provides power for the flow of water in the first flow pipe 213, ensuring that the water can enter the filter module 100 through the first inlet 120 with stable pressure and flow rate.

[0048] The two ends of the second circulation pipe 220 are connected to the first outlet 130 and the inlet pipe 212. Through this connection, the water flowing out of the filter device 110 can return to the first flow pipe 213 through the second circulation pipe 220 and then re-enter the filter device 110, forming an internal circulation filtration of the water.

[0049] In this embodiment of the application, a water outlet pipe 221 is provided on the second circulation pipe 220, and the water outlet pipe 221 is connected to the second circulation pipe 220; a water outlet end 250 is provided on the water outlet pipe 221, and a second regulating valve 222 is provided between the water outlet pipe 221 and the second circulation pipe 220.

[0050] like Figure 3 As shown, the outlet pipe 221 provides a discharge channel for water that has reached the required cleanliness level after circulation filtration. The second regulating valve 222 can precisely control the water flow in the outlet pipe 221. When the water has not yet reached the ideal cleanliness level, the second regulating valve 222 closes, preventing water from being discharged and allowing it to continue circulating and filtering within the circulation regulating pipe 200 and the filter module 100. After the water has undergone multiple circulation filtrations and reached the set cleanliness standard, the second regulating valve 222 opens, allowing clean water to be discharged from the filter mechanism through the outlet 250 for normal use. This design not only ensures that the filter mechanism can output water that meets the requirements, but also achieves flexible control of the filtration process through valve adjustment, improving the overall efficiency and reliability of the filter mechanism.

[0051] During the water filtration process described above, since the first circulation pipe 210 is connected to the filter media device 230, the valve of the filter media device 230 can be closed after the filter membrane is formed to prevent the filter media from re-entering the filter device 110.

[0052] In this embodiment, the disinfection module 300 is installed on the water outlet pipe 221.

[0053] The disinfection module 300 is installed on the outlet pipe 221 to ensure that the filtered water undergoes a final, comprehensive, and effective disinfection treatment before being discharged from the filtration system. In actual operation, after the water undergoes deep filtration by the filtration module 100 and multiple circulation filtrations by the circulation regulating pipe 200, it flows out through the outlet pipe 221. At this point, the ultraviolet disinfection device installed on the outlet pipe 221 begins to function. Utilizing the bactericidal properties of ultraviolet light, it irradiates the water about to be discharged, destroying the cellular structure of residual bacteria, viruses, and other microorganisms in the water, thereby achieving thorough sterilization and disinfection, ensuring the hygiene and safety of the output water, and meeting the water quality requirements of various usage scenarios.

[0054] In this embodiment of the application, a connecting pipe 260 is provided on the first flow pipe 213, the connecting pipe 260 connects the first flow pipe 213 and the first outlet 130, and a third regulating valve 261 is provided on the connecting pipe 260.

[0055] The above structure enables the regeneration of the filter membrane. The main processes involved in filter membrane regeneration are: like Figure 5 As shown, the third regulating valve 261 is opened, so that the first flow pipe 213 is connected to the first outlet 130, so that the driving device 211 can drive the water to enter the hollow structure of the filter rod in the filter device 110 through the connecting pipe 260 from the first outlet 130. The water will impact the filter membrane on the filter rod, causing the filter membrane to be broken up and flushed into the first circulation pipe 210.

[0056] Meanwhile, in this embodiment, the connection pipe 260 is connected to the second circulation pipe 220, which allows the rinsed filter material to enter the first flow pipe 213 from the second circulation pipe 220, thereby realizing the circulation treatment of the filter membrane medium.

[0057] In this embodiment of the application, the first flow pipe 213 is provided with a fourth regulating valve 215, which disconnects or connects to the first water inlet 120.

[0058] In the above process, when the fourth regulating valve 215 disconnects the connection between the first inlet 120 and the first flow pipe 213, the water driven by the drive device 211 enters the filter device 110 through the first outlet 130, performing a backwash on the filter membrane within the filter device 110. This backwashing effectively removes impurities and contaminants adhering to the surface of the filter membrane, restoring its original filtration performance and achieving membrane regeneration. Compared to existing membrane regeneration processes, this regeneration process improves the membrane formation efficiency.

[0059] When the fourth regulating valve 215 connects the first inlet 120 and the first flow pipe 213, and the third regulating valve 261 is closed, the system returns to normal filtration mode. External water can enter through the inlet 240, and after being driven by the drive device 211, it enters the filter device 110 for filtration. This design allows the filtration mechanism to flexibly switch operating modes according to actual needs, ensuring filtration effect, extending the service life of the filter membrane, and reducing operating costs. In addition, precise control of each regulating valve enables automated management of the filtration process, further improving the stability and reliability of the entire filtration system.

[0060] In this embodiment of the application, the second circulation pipe 220 is provided with a second flow pipe 223 and a third flow pipe 224, which are connected or disconnected by a fifth regulating valve; the outlet pipe 221 is connected to the second flow pipe 223; the second flow pipe 223 is connected to the first outlet 130, and the third flow pipe 224 is connected to the inlet pipe 212.

[0061] By splitting the second circulation pipe 220 into a second flow pipe 223 and a third flow pipe 224, and using a fifth regulating valve to connect or disconnect them, a more flexible control method is provided for the operation of the filtration mechanism. In actual operation, when it is necessary to backwash the filter membrane in the filtration device 110 to achieve filter membrane regeneration, the fourth regulating valve 215 can be closed and the fifth regulating valve can be opened to disconnect the second flow pipe 223 from the first flow pipe 213. At this time, the water driven by the drive device 211 enters the filtration device 110 only through the first outlet 130 for backwashing. The washed filter media enters the inlet pipe 212 through the third flow pipe 224 and is repeatedly backwashed by the drive device 211. After multiple cycles, the fifth regulating valve can be closed and the fourth regulating valve 215 can be opened, and the washed filter media can be driven by the drive device 211 again to regenerate the filter membrane, achieving normal water filtration and participating in the next round of filtration. This design not only optimizes the membrane regeneration process but also improves the efficiency of water circulation filtration, ensuring stable operation of the filtration unit under different working modes.

[0062] In this embodiment of the application, the filter module 100 is provided with a drain outlet 140, which is located at the bottom of the filter module 100.

[0063] The drain outlet 140 of the filter module 100 is located at the bottom. During the filtration process, as the water is continuously purified, some intercepted impurities, particles, and sediments will gradually accumulate at the bottom of the filter device 110. The drain outlet 140 is located at the bottom, which allows these accumulated contaminants to be easily discharged from the filter module 100, preventing contaminants from accumulating in the filter device 110 for a long time and affecting the filtration effect and normal operation of the equipment.

[0064] When the filter unit needs regular maintenance and cleaning after operating for a period of time, the residual water and deposited dirt inside the filter device 110 can be completely discharged by opening the drain switch on the drain port 140. This not only helps to keep the inside of the filter device 110 clean, but also extends the service life of the filter media (such as diatomaceous earth pre-coated membrane, perlite pre-coated membrane, etc.) and reduces the frequency and cost of replacing the filter media.

[0065] Furthermore, the drain outlet 140 also facilitates troubleshooting and handling of the filtration mechanism. For example, when a decrease in filtration efficiency or equipment malfunction is detected, the discharged material can be observed through the drain outlet 140 to preliminarily determine whether there are problems such as filter media blockage or excessive dirt accumulation. This allows for targeted maintenance and handling, improving the efficiency of troubleshooting and ensuring the stable operation of the filtration mechanism.

[0066] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
