Description

Technical Field

[0001] This utility model relates to the field of self-cleaning filter technology, and in particular to a detachable device and filter for self-cleaning marine organism residue filtration. Background Technology

[0002] A coastal power plant's first-phase unit is equipped with a seawater chlorination system. Seawater enters the seawater chlorination electrolyzer after passing through a self-cleaning filter. The main functions and characteristics of the self-cleaning filter are as follows:

[0003] ① The seawater entering the seawater chlorination electrolysis cell is filtered to remove marine organism remains and sediment impurities, preventing the electrolysis cell from being blocked by foreign objects and ensuring the safe and reliable operation of the system.

[0004] The filtration effect of the self-cleaning filter directly affects the operating efficiency and safety of the seawater electrolyzer. Impurities in the seawater entering the electrolyzer may cause short circuits in the anode and cathode plates, resulting in the loss of chlorine production. Long-term operation may lead to damage to the electrode plates, causing significant property losses.

[0005] The self-cleaning filtration equipment mainly consists of a shell, a cylindrical filter screen, a suction box, a rotating shaft, a drain pipe, and related control valves. The cylindrical filter screen and the suction box each play important roles in the operation of the equipment, and their specific functions in the system are as follows:

[0006] ① The function of the filter screen: The filter screen is made of seawater resistant duplex steel and is mainly used to intercept marine organism remains and silt impurities in seawater. Depending on the flow rate and seawater cleanliness requirements, different filter mesh sizes are selected for different working conditions.

[0007] ②The function of the suction box: The suction box is fixed on the rotating shaft. The center of the rotating shaft is a hollow channel. The lower part of the rotating shaft is connected to the drain pipe. A pneumatic drain valve is installed on the drain pipe. The pneumatic drain valve is automatically controlled by the system. After the drain valve is opened, the pressure on the part of the suction box covering the filter screen decreases. Under the action of external pressure, marine organism remains and mud and sand impurities on the surface of the filter screen enter the suction box and are discharged into the ditch through the drain pipe, preventing impurities from clogging the filter screen and causing the seawater flow to be interrupted.

[0008] Although the suction box can remove most of the impurities intercepted by the filter, sticky marine organisms (such as jellyfish and seaweed) or woven bags attached to the filter surface are difficult to remove, which can cause the filter to become clogged or penetrate the filter and enter the electrolytic cell, resulting in system failure or equipment malfunction. Utility Model Content

[0009] In view of this, the purpose of this utility model is to propose a detachable device for self-cleaning marine organism residue filtration, which can solve the problem that sticky marine organisms (such as jellyfish and seaweed) or woven bags are difficult to remove after adhering to the filter screen surface, thereby improving the filtration efficiency and safety of the equipment.

[0010] According to one aspect of the present invention, a detachable device for filtering self-cleaning marine organism residues is provided, the device comprising a mounting groove and a flexible scraper embedded in the mounting groove;

[0011] The mounting slot is detachably disposed on one side of the suction box of the self-cleaning filter, and the flexible scraper extends along a first direction, with its extended end contacting the inner surface of the filter screen of the self-cleaning filter.

[0012] In the aforementioned technical solution, the device operates primarily through contact between a flexible scraper and the inner surface of the self-cleaning filter screen. During operation, the flexible scraper moves directionally along the inner surface of the screen, effectively scraping away marine debris and other impurities, thus achieving self-cleaning. Its mounting slot features a detachable design, facilitating installation and disassembly. This allows for easy maintenance of the device itself, replacement of the flexible scraper, or more thorough cleaning of the filter screen when necessary. The flexible scraper's ability to continuously or periodically scrape the filter screen throughout operation eliminates the tedious process of frequent manual intervention to clean marine debris, significantly enhancing the filter's automation level while improving its efficiency.

[0013] In some embodiments, the height of the flexible scraper is matched to the suction box.

[0014] In the aforementioned technical solution, the height of the flexible scraper in this self-cleaning filter device is precisely matched to the suction box, with the two in a close fit. During operation, the flexible scraper fully conforms to the side wall of the suction box and the corresponding filter screen area, achieving excellent adhesion to the inner surface of the filter screen and realizing full coverage of the area to be cleaned. This precise matching ensures that the scraping path of the scraper closely matches the filter screen structure, effectively removing impurities such as marine organism remains from the filter screen and reducing the residue rate around the suction box.

[0015] In some embodiments, the flexible scraper extends along a first direction, making the flexible scraper prism-shaped; the tip of the flexible scraper abuts against the inner surface of the filter screen of the self-cleaning filter, and the tip deforms to one side, so that the prism adaptably fits the inner surface of the filter screen.

[0016] In the aforementioned technical solution, the tip of the scraper forms an abutment relationship with the inner surface of the filter screen, and undergoes elastic deformation to one side during the interaction process, thereby achieving adaptive adhesion between the cylindrical surface and the inner surface of the filter screen. This innovative design based on deformation adhesion allows the flexible scraper to conform to the curved contour of the filter screen, ensuring stable contact pressure and contact area between the scraper and the filter screen, thus improving the scraping efficiency of marine organism debris. When the triangular prism-shaped flexible scraper interacts with the inner surface of the filter screen, the local deformation of its tip generates a concentrated scraping force, which can effectively penetrate the debris adhesion layer and achieve deep cleaning. At the same time, the continuous adhesion characteristic of the cylindrical surface ensures the uniform distribution of scraping force on the filter screen surface, avoiding filter screen structural damage caused by local stress concentration. During the deformation process, the elastic modulus of the flexible scraper matches the mechanical properties of the filter material, forming an adaptive pressure adjustment mechanism. This ensures that the scraping force achieves a dynamic balance between cleaning efficiency and filter protection, effectively solving the problems of local cleaning dead spots and filter damage caused by uneven scraping force in traditional devices.

[0017] In some embodiments, both cylindrical surfaces of the flexible scraper are filled with a plurality of first flexible protrusions.

[0018] In the aforementioned technical solution, the flexible scraper of the self-cleaning filter device has first flexible protrusions on both cylindrical surfaces, which form multiple contact points when in contact with the inner surface of the filter screen. Compared to smooth cylindrical surfaces, these protrusions significantly optimize contact mechanical properties, uniformly distributing the pressure of the flexible scraper on the filter screen to multiple contact areas through a multi-point contact mechanism, thereby achieving a homogeneous distribution of scraping force. This optimized mechanical distribution mechanism ensures effective removal of marine organism debris while effectively avoiding filter screen structural damage caused by localized stress concentration, significantly reducing the risk of filter screen damage. When the tip of the flexible scraper abuts against the filter screen and deforms, the protrusions can conform to the micro-geometric features of the filter screen, filling surface depressions or adapting to uneven areas, forming a multi-point adaptive fit. This microstructural adaptation mechanism is particularly suitable for filter screens with complex shapes or textured surfaces, further improving cleaning efficiency by enhancing the contact compliance between the scraper and the filter screen.

[0019] In some embodiments, the flexible scraper extends along a first direction, making the flexible scraper prism-shaped; the front end face of the flexible scraper abuts against the inner surface of the filter screen of the self-cleaning filter.

[0020] In the above technical solution, the flexible scraper adopts a quadrangular prism structure, with its front end face forming an abutment with the inner surface of the filter screen. Compared to a triangular prism design, the quadrangular prism flexible scraper has a larger contact surface area, and its front end face has higher flatness and stability. This geometric optimization can significantly improve the contact mechanical properties, enabling a more uniform distribution of scraping force on the filter screen surface, thereby enhancing the scraping efficiency of marine organism debris.

[0021] In some embodiments, the front end face of the flexible scraper is provided with a plurality of second flexible protrusions.

[0022] In the above technical solution, the second flexible protrusion, positioned on the front end of the flexible scraper, creates multiple points of force application when the scraper contacts the inner surface of the filter screen. These protrusions can act more precisely on marine organism debris, increasing the localized scraping intensity through multi-point force application, effectively removing firmly attached debris. Simultaneously, they can penetrate the complex textures or pores of the filter screen surface, reaching hard-to-reach areas for a more comprehensive cleaning effect.

[0023] In some embodiments, the flexible scraper extends to make the ratio of the working diameter of the self-cleaning filter to the inner surface diameter of the filter screen 1.2-1.4:1.

[0024] In the above technical solution, the extended design of the flexible scraper increases its contact area with the inner surface of the filter screen, thereby enabling more comprehensive removal of marine organism debris and effectively improving cleaning efficiency. This ratio optimizes the cleaning range while fully considering the principles of fluid mechanics. When water flows onto the flexible scraper, the appropriate working diameter ratio ensures that the contact area between the flexible scraper and the filter screen is maintained under the force of the water flow, while avoiding excessive swaying or deformation, thus maintaining the stability of the cleaning force.

[0025] According to another aspect of the present invention, a self-cleaning filter is provided, which is provided with a detachable device for self-cleaning marine organism residues as described above.

[0026] In the above technical solution, the advantages of the self-cleaning filter depend on the above device, which will not be elaborated here. Attached Figure Description

[0034] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are only for illustrating the present invention and do not limit the scope of the present invention. Similarly, the following embodiments are only some embodiments of the present invention, not all embodiments.

[0041] The mounting slot 2 is detachably mounted on one side of the suction box 1 of the self-cleaning filter. It should be noted that the optimal arrangement is for the mounting slot 2 to be detachably mounted on the side of the suction box 1 of the self-cleaning filter closer to the direction of rotation. That is, the mounting slot 2 and the suction box 1 are arranged sequentially along the direction of rotation G. The purpose of this arrangement is to ensure that sticky marine organisms (such as jellyfish, seaweed) or woven bags scraped off by the device can be immediately sucked away by the suction box 1. Please refer to [link to relevant documentation]. Figure 2 The installation method for the mounting groove 2 and the suction box 1 can be achieved by drilling and tapping holes on one side of the suction port 11 of the suction box 1 (6 in the figure shows the drilling point; the number of holes can be set according to actual needs, ensuring a stable installation that is not prone to shaking; the figure shows four holes spaced evenly from top to bottom). The scraper mounting groove 2 is then fixed with bolts for easy disassembly and installation. The groove 21 of the mounting groove 2 opens from top to bottom, and the bottom groove 21 is not through-hole to ensure that the scraper 3 installed in the groove will not fall off. The height of the flexible scraper 3 matches that of the suction box 1.

The scraper mounting part 31 and the slot 21 of the mounting groove 2 cooperate to form a nesting, which facilitates the disassembly and installation of the flexible scraper.

[0043] Please see Figure 3 -A3, the flexible scraper 3 extends along a first direction T, and its extended end 32 contacts the inner surface 01 of the filter screen of the self-cleaning filter.

[0051] (2) This utility model requires very little modification to the original equipment, has a reasonable and simple structural design, is easy to implement and has low manufacturing cost. The grooved suction port of the suction box and the fixed end of the scraper are designed in a reasonable way, making it easier to replace the scraper and make the processing of spare parts simpler.

[0052] (3) The scraper moves along the surface of the filter screen. The dynamic and static friction will wear down the scraper.
