Description

Technical Field

[0001] This utility model relates to the field of filter cleaning technology, and in particular to an auxiliary device for filter cleaning. Background Technology

[0002] A filter is an optical device that selectively transmits light of a specific wavelength through absorption or interference effects. Filter cleaning is the safe removal of contaminants (dust, fingerprints, oil stains, etc.) from the surface of a filter using physical or chemical methods.

[0003] The working principle of traditional filter cleaning auxiliary devices is typically based on a core idea: filters are loaded in batches onto a support frame and immersed in a common, reusable cleaning solution tank for processing. Multiple filters are inserted vertically or horizontally into the frame and then immersed in the tank filled with cleaning solution. Cleaning is achieved through ultrasonic cavitation or fluid scouring generated within the tank. Since the filters share the same cleaning solution, contaminants detached from one filter can become suspended and potentially redeposited onto the next, leading to cross-contamination. Simultaneously, the cleaning solution becomes rapidly contaminated with continuous use, resulting in decreased overall efficiency and requiring frequent, large-volume replacements. This leads to high operating costs and generates substantial waste liquid. The dense arrangement of filters on the support frame can also cause them to block each other, hindering the uniform distribution of the cleaning solution flow field and ultrasonic field, creating "shadow zones" and resulting in inconsistent cleaning effects. Furthermore, slight vibrations and friction within the slots, as well as impacts from debris detached from other filters in the shared tank, increase the risk of surface scratches or membrane damage. The cleaning, rinsing, and drying steps are strictly separated in both space and time. When it is necessary to adjust the process parameters of a single link (such as changing the cleaning fluid formula or changing the ultrasonic frequency), the entire production line must be interrupted, and the large public tank must be emptied and cleaned. It is difficult to achieve rapid production changeover or to carry out refined and flexible process customization for filters of different materials and types of contamination. Utility Model Content

[0004] The technical problem this invention aims to solve is that the "batch co-tank" structure of traditional devices is the root cause of all their defects. It directly leads to cross-contamination during the cleaning process and rapid overall deterioration of the cleaning solution. To solve the contamination problem, the entire tank of liquid must be replaced frequently. However, this is not only costly, but also time-consuming due to the large tank size, which severely restricts the flexibility of production rhythm and the ability to quickly switch between different processes. This rigidity in process adjustment, in turn, forces filters with different requirements to accept the same set of cleaning parameters as a "compromise," further exacerbating the problem of poor cleaning effect or damage risk caused by uneven cleaning action and the inability to handle individual needs.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A filter cleaning auxiliary device includes a cleaning box, a waste liquid tank fastened to the bottom of the cleaning box, and water inlet pipes arranged sequentially on the outside of the cleaning box. Several sets of independent gate sleeves are linearly arranged inside the cleaning box, and an independent cleaning chamber is formed between two sets of independent gate sleeves. A cleaning auxiliary module is provided in the independent cleaning chamber, and the cleaning auxiliary module is connected to the water inlet pipe. An air pressure box that docks with the cleaning auxiliary module is provided on the other side of the cleaning box.

[0006] The beneficial effects of this invention are as follows: Each independent cleaning chamber and the cleaning auxiliary module installed in it constitute a completely physically isolated cleaning unit. The cleaning fluid used in each unit is supplied and discharged independently, which completely blocks the transmission path of pollutants between different filters. The structure ensures the cleanliness of the cleaning process and greatly improves the consistency and reliability of product yield. The independent, small-flow, precise fluid supply method replaces the large amount of cleaning fluid required for traditional whole-tank immersion. At the same time, the cleaning fluid is used and discharged immediately, avoiding the overall performance degradation caused by continuous pollution. There is no need to frequently replace the whole tank of liquid. This directly and significantly reduces the consumption of high-purity cleaning fluid, the amount of waste liquid to be treated, and the related energy and material costs, which is in line with the concept of green manufacturing.

[0007] Furthermore, a diversion plate is integrated at the bottom of the cleaning tank, with several diversion holes distributed on the diversion plate and several gate slots linearly opened along the diversion plate. The gate slots are used to assist in the sealing and protection of the independent gate sleeve. Several installation holes for installing water inlet pipes and air pressure boxes are linearly opened on both sides of the cleaning tank, and positioning holes for installing independent gate sleeves are linearly opened on the cleaning tank.

[0008] Furthermore, a water box is integrated at the end of the water inlet pipe, and an inlet valve and an inlet controller are integrated on the water box. A delivery pipe is connected to the water box.

[0009] Furthermore, a positioning frame is fitted onto the independent gate sleeve, and positioning bolts are installed on both sides of the positioning frame. The outside of the independent gate sleeve is covered with a waterproof sleeve, and a lifting plate is integrated into the independent gate sleeve. Lifting rods that pass through the positioning frame are provided on both sides of the top of the lifting plate, and a cylinder is provided at the top of the lifting rod. The cylinder controls the lifting rod to drive the lifting plate to rise and fall.

[0010] Furthermore, the cleaning auxiliary module includes a semi-ring and a bottom integrated drain semi-ring. The semi-ring and the drain semi-ring form a circular shape. Several drain holes are distributed on the drain semi-ring, and a slot for inserting a plate is provided on the top of the semi-ring.

[0011] Furthermore, sealing rings are integrated on both sides of the semi-ring sleeve. Several first tensioning airbag wheels and second tensioning airbag wheels are respectively provided along the inner side of the two sets of sealing rings. A first one-way valve port is opened between the two sets of first tensioning airbag wheels, and a second one-way valve port is opened between the two sets of second tensioning airbag wheels. An air pipe connected to the first one-way valve port is provided outside one set of sealing rings, and a water pressure pipe is connected outside the other set of sealing rings.

[0012] Furthermore, the pressure box is equipped with a pressure pump and an externally electrically connected data panel. Several sets of air exchange slots are distributed in the pressure box, and the pressure box is connected to the air pipe.

[0013] Furthermore, several sets of support columns are installed at the bottom of the waste liquid tank, and several sets of sewage pipes and an integrated sewage valve are arranged along the outside of the waste liquid tank.

[0014] The beneficial effects of adopting the above-mentioned further solutions are: Multiple independent cleaning units can work in parallel or asynchronously. The central control system can independently set and execute differentiated cleaning parameters (such as cleaning time, water pressure, and airflow drying intensity) for each unit. This allows the device to flexibly adapt to customized cleaning processes for filters of different sizes, membrane layers, and types of contamination, supporting flexible production of multiple varieties and small batches, and responding quickly to changes in production needs. The cleaning auxiliary module is designed for single filters. Its semi-ring and tensioning airbag wheel structure can stably center the filter and fully expose its surface to the optimized flow field, without the shadow area formed by adjacent filters. Combined with adjustable water and air pressure, it can form a uniform, gentle and effective rinsing, avoiding mutual bumping and friction caused by traditional dense inserts, and reducing the risk of the filter surface and precision film layer being scratched during the cleaning process.

[0017] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

In the description of this application, "a plurality of" means two or more, unless otherwise precisely specified.

[0019] Example 1; as Figure 1 - Figure 5 As shown, a filter cleaning auxiliary device includes a cleaning tank 1, a waste liquid tank 2, a water inlet pipe 3, an independent gate sleeve 4, a cleaning auxiliary module 5, and a pressure tank 6. The cleaning tank 1 serves as the main structure, and its bottom is connected to the waste liquid tank 2 by a diversion plate 103. The diversion holes 105 regularly opened on the diversion plate 103 are used to guide the waste liquid, and the gate grooves 104 arranged linearly on it provide positioning for the falling seal of the independent gate sleeve 4. The cleaning tank 1 has linearly opened mounting holes 101 on both sides for mounting the water inlet pipe 3 and the air pressure box 6, respectively. Several sets of independent gate sleeves 4 are arranged linearly inside the cleaning tank 1. Each set of two adjacent independent gate sleeves 4 forms an independent cleaning chamber. Each independent gate sleeve 4 is covered with a waterproof sleeve 403 and has an integrated lifting plate 404 inside. The lifting plate 404 is connected to the cylinder 406 through the lifting rod 405 at the top. Driven by the cylinder 406, the entire unit can be raised and lowered, thereby controlling the opening and closing of the independent cleaning chamber. Each independent cleaning chamber is fixedly installed with a cleaning auxiliary module 5. The core of the module is a circular frame consisting of a semi-ring 501 and a bottom drain semi-ring 502. The drain semi-ring 502 is densely covered with drain holes 503. The top of the semi-ring 501 is provided with an insertion slot for inserting a filter. The two sides of the semi-ring 501 are integrated with sealing rings 506. The inner side of the sealing ring 501 is provided with multiple sets of first tension airbag wheels 504 and second tension airbag wheels 508. The water inlet pipe 3 passes through the water box 301, water inlet valve 304 and water inlet controller 303 integrated at its end, and finally connects to the water pressure pipe 507 outside the sealing ring 506 on one side of the cleaning auxiliary module 5 via the delivery pipe 302. The pressure box 6 is equipped with a pressure pump 603. It exchanges gas with the external environment through the air exchange slot 602 opened on the box body, and is connected to the air pipe 510 outside the sealing ring 506 on the other side of the cleaning auxiliary module 5 through the pipeline. The cleaning box 1 is linearly provided with positioning holes 102 for the installation of independent gate sleeve 4. The independent gate sleeve 4 can be installed through the positioning holes 102 and the positioning bolts 402.

[0020] During operation, the operator first vertically inserts the filter to be cleaned into the insert slot of the cleaning auxiliary module 5 of an idle cleaning unit. After the unit is started, its corresponding independent gate sleeve 4 is lowered under the drive of the cylinder 406, so that the waterproof sleeve 403 is tightly pressed into the gate slot 104 of the diversion plate 103 of the cleaning box 1, thereby forming a physically sealed independent cleaning chamber around the filter. Subsequently, the control system commands the corresponding water inlet valve 304 to open, and the cleaning fluid is injected into the cleaning auxiliary module 5 through the water inlet pipe 3, water box 301, and delivery pipe 302 via the water pressure pipe 507. The liquid enters through the first one-way valve port 505 and inflates the first tensioning airbag wheel 504, so that it gently and stably clamps and fixes the filter from both sides. Meanwhile, the cleaning fluid fills the space formed by the semi-ring 501, the draining semi-ring 502 and the filter, and thoroughly soaks or rinses both sides of the filter. After washing, the liquid flows down through the drain hole 503 of the draining semi-ring 502 and flows into the waste liquid tank 2 through the diversion hole 105 of the diversion plate 103. The bottom of the waste liquid tank 2 is raised by the support column 201, and the sewage pipe 202 connected to it can discharge the waste liquid in a concentrated manner under the control of the sewage valve 203. After that, the first tensioning airbag wheel 504 is depressurized and released.

[0021] Example 2: Please refer to Figure 1 - Figure 6 Based on Example 1, sensing and adaptive control functions are further added, making the device more intelligent and the process control more precise.

[0022] A first one-way valve port 505 is provided between the two sets of first tensioning airbag wheels 504, and a second one-way valve port 509 is provided between the two sets of second tensioning airbag wheels 508. One set of sealing rings 506 is provided with an air pipe 510 connected to the first one-way valve port 505, and the other set of sealing rings 506 is connected with a water pressure pipe 507.

[0023] A high-precision flow sensor (such as the IFMSM series) is added near the water box 301 of the inlet pipe 3 to monitor and provide feedback on the volume of cleaning fluid supplied to each independent unit in real time, ensuring accurate and controllable dosage. Digital pressure sensors (such as the SMCPSE550 series) are integrated on the air pipe 510 and water pressure pipe 507 of the cleaning auxiliary module 5 to continuously monitor the clamping pressure of the tensioning airbag wheel and the pressure of the cleaning and drying media. In addition, position sensors (such as Omron E2E series proximity sensors) are installed at the lifting rod 405 or positioning frame 401 of the independent gate sleeve 4 to accurately detect and provide feedback on the lifting stroke and positioning status of the gate sleeve, ensuring reliable opening and closing of the sealed cavity. The data screen 601 externally connected to the pressure box 6 is used to centrally display the real-time data of each sensor, current process parameters, and equipment status. In terms of materials, to meet the requirements of high cleanliness and chemical corrosion resistance, the main body of the semi-ring 501 and the drainage semi-ring 502 of the cleaning auxiliary module 5 is made of polyetheretherketone (PEEK) or 316L stainless steel with a polished surface. The airbag parts of the first tensioning airbag wheel 504 and the second tensioning airbag wheel 508 are made of medical-grade flexible silicone, and the internal support is made of porous ceramic to ensure uniform pressure distribution and sensitive response. The waterproof sleeve 403 of the independent gate sleeve 4 is made of fluororubber (FKM) to ensure long-term sealing reliability between it and the metal gate groove 104.

[0024] When working, the process adds intelligent feedback and adjustment links to the process of Example 1. After the filter is inserted and sealed, the system not only executes the preset cleaning program, but also monitors the clamping force in real time through the pressure sensor to prevent the filter from being deformed or damaged due to improper pressure. It also dynamically adjusts the air intake and liquid pressure through closed-loop control to keep it constant. A flow sensor ensures a consistent liquid supply for each cleaning cycle, preventing waste or incomplete cleaning. During the drying stage, the pressure pump 603 in the pressure tank 6 supplies drying gas according to a set value. A pressure sensor monitors the drying gas flow pressure, which is displayed in real time on the data screen 601. Operators can optimize the process based on this information. A position sensor ensures that the independent gate sleeve 4 is accurately in the sealed or open position before each step begins, guaranteeing the safety and continuity of the process. The above working principle can be summarized as follows: by constructing multiple sealed cavities separated by independent gate sleeves 4, and equipping them with independent fluid supply, discharge and control units, the physical isolation and parallel asynchronous processing of the filter cleaning process are realized. Its core lies in using the inflatable air bladder wheel in the cleaning auxiliary module 5 to achieve non-destructive flexible clamping and fixation of the filter, and directly use it as a distribution channel for cleaning fluid and drying gas. From filter insertion, sealing of the cavity, liquid cleaning and discharge, to airflow drying and cavity opening, the entire process is completed continuously in one station, eliminating cross-contamination, and supporting personalized customization of process parameters for different filters.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
