Description

Technical Field

[0001] This application relates to the field of filtration and slag separation technology, and in particular to a pre-embedded trench slag-separating floor drain. Background Technology

[0002] The trench drain is an important component of the building drainage system. Its design and function are aimed at effectively draining water while preventing impurities from entering the drainage pipes, thereby keeping the pipes unobstructed and extending their service life.

[0003] The trench drain combines the drainage function of a trench with the impurity blocking function of a drain, offering advantages such as high drainage efficiency, excellent impurity isolation, and ease of cleaning and maintenance. These drains are widely used in bathrooms, kitchens, laundry rooms, and other areas of residential buildings, commercial buildings, and public facilities, as well as in places where wastewater containing impurities needs to be discharged.

[0004] However, in the relevant technical field, traditional floor drain designs often suffer from problems such as poor solid waste interception and difficult maintenance, failing to meet the needs of modern industrial and commercial venues for efficient and easy-to-maintain floor drains. Utility Model Content

[0005] This application provides a pre-embedded trench drain with solid residue separation, which can achieve efficient drainage and effectively solve the problem of solid residue blockage.

[0006] This application provides a pre-embedded trench drain with slag separation, installed in a predetermined area on the ground, with a trench channel provided within the predetermined area. The pre-embedded trench drain with slag separation includes:

[0007] The assembly frame has a drain outlet in the middle and is at least partially fixed to the inner wall of the underground passage. Before the floor is tiled, the assembly frame is at least partially embedded in the corresponding area of ​​the underground passage.

[0008] The slag-blocking structure is connected to the assembly frame and seals the drain outlet. The outer circumference of the slag-blocking structure is spaced apart from the inner wall of the underground passage.

[0009] The slag-blocking structure has filter holes at the bottom and sides, which allow it to intercept solid residues.

[0010] The pre-embedded trench drain in the above structure is installed in a specific pre-designated area on the ground. Within the pre-designated area, a drainage channel is specially excavated for drainage.

[0011] The pre-embedded trench drain with slag trap mainly consists of two parts: an assembly frame and a slag trap structure. The assembly frame, as the main structure, has a drain outlet in its center for water discharge. Before tiling the floor, at least a portion of the assembly frame needs to be pre-embedded in the corresponding position of the drain channel to ensure a secure connection. The fixed connection part of the assembly frame fits tightly against the inner wall of the drain channel, enhancing overall stability and sealing.

[0012] The sludge-blocking structure is connected to the mounting frame and seals the area where the drain outlet is located, serving to intercept solid debris. The outer perimeter of the sludge-blocking structure maintains a certain distance from the inner wall of the drainage channel, thus not obstructing water flow while effectively isolating impurities. In particular, filter holes are cleverly designed into the bottom and sides of the sludge-blocking structure. These filter holes allow water to flow smoothly while simultaneously trapping solid debris inside the sludge-blocking structure, preventing it from entering the drainage system and causing blockages. In this structure, even if solid debris clogs the bottom filter holes, drainage can still be achieved through the side filter holes, achieving efficient and stable drainage.

[0013] In some examples, the slag-blocking structure is prismatic in shape and includes a bottom or top surface and multiple side surfaces. Filter holes are provided on the bottom or top surface and at least one side surface of the slag-blocking structure.

[0014] Alternatively, the slag-blocking structure may be cylindrical in shape, and may include a bottom or top surface and a peripheral surface, with filter holes provided on both the bottom or top surface and the peripheral surface.

[0015] The aforementioned sludge-filtering structure employs a specific shape to achieve efficient drainage. Specifically, the sludge-filtering structure may be prismatic, consisting of a bottom or top surface and multiple side surfaces, with filter holes evenly distributed on the bottom or top surface and at least one side surface. This design ensures that even if the bottom filter holes are at risk of clogging due to solid residue, water can still flow smoothly through the side filter holes. The shape of the sludge-filtering structure can be a triangular prism, square prism, pentagonal prism, hexagonal prism, etc.

[0016] The sludge-filtering structure may also be designed as a cylinder, comprising a bottom or top surface and surrounding peripheral surfaces, both of which are provided with filter holes. This design also aims to prevent clogging of the bottom filter holes, maintaining stable drainage efficiency through the filter holes on the peripheral surfaces.

[0017] In summary, regardless of whether it is a prismatic or cylindrical design, the slag-blocking structure can effectively address the clogging challenges that solid residues may cause by opening filter holes on multiple sides, thereby achieving efficient and stable drainage performance.

[0018] In some examples, the sludge-filtering structure is in the shape of a quadrangular prism. The sludge-filtering structure includes a bottom or top surface and four sides. Multiple filter holes are opened on the bottom or top surface and the four sides of the sludge-filtering structure. The bottom or top surface with filter holes and the four sides work together to form a five-sided drainage filtration structure.

[0019] In the above structure, the sludge-filtering structure takes the form of a quadrangular prism, consisting of a bottom or top surface and four sides. Multiple filter holes are distributed on the bottom or top surface and the four sides of this sludge-filtering structure. These bottom or top surfaces with filter holes cooperate with the four sides to form a five-sided drainage filtration structure.

[0020] The five-sided water filtration structure described above is designed to effectively intercept and filter impurities and particulate matter in the water, ensuring clean and unobstructed water flow. The bottom or top surface serves as a support structure, with evenly distributed filter holes, guaranteeing filtration efficiency while preventing clogging caused by excessive local pressure. The four sides guide the water flow and increase the filtration area, allowing the water to make more thorough contact with the filter holes as it passes through the filter structure, thereby further enhancing the filtration effect.

[0021] In some examples, a separable filter basket is added to the inside or outside of the grease barrier structure. Solid residues inside the grease barrier structure are intercepted in the filter basket, and the filter basket can transfer and clean the solid residues inside the grease barrier structure by separating it.

[0022] A removable filter basket has been added inside the aforementioned grease trap structure. The main function of the filter basket is to intercept and collect solid residues within the grease trap structure. When it is necessary to clean these solid residues, they can be easily transferred and cleaned by simply separating the filter basket from the grease trap structure, thereby effectively maintaining the cleanliness and unobstructed flow of the grease trap structure.

[0023] Furthermore, this design not only improves the ease of cleaning solid residues but also enhances the overall efficiency and lifespan of the filter structure. The detachable nature of the filter basket means that residue cleaning can be completed quickly without completely disassembling the filter structure, significantly saving time and labor costs.

[0024] In some examples, the slag-blocking structure is detachably connected to the mounting frame. Alternatively, the slag-blocking structure is integrated with the mounting frame.

[0025] In this application, the slag-separating structure and the assembly frame are connected in a detachable manner, facilitating disassembly and cleaning. Alternatively, the slag-separating structure can be designed as an integral part of the assembly frame, making it non-separable, as needed.

[0026] Furthermore, the specific connection method between the slag-blocking structure and the assembly frame can be flexibly selected according to actual needs. For example, a detachable connection can be achieved using fasteners such as bolts and clips, allowing users to quickly assemble and disassemble the slag-blocking structure as needed. An integrated design, on the other hand, may use processes such as injection molding and welding to firmly combine the slag-blocking structure with the assembly frame, thereby improving overall stability and durability.

[0027] In some examples, the pre-embedded trench drain with slag separation also includes at least one fastener, and the slag separation structure is connected to the mounting frame via the fastener.

[0028] In the aforementioned structure, the fasteners are responsible for tightly connecting the slag-separating structure to the assembly frame, ensuring the stability and reliability of the entire floor drain system. This connection method not only effectively improves the installation efficiency of the floor drain but also further enhances its ability to withstand various external forces during use, such as water flow impact and foot traffic, thereby significantly extending the service life of the floor drain.

[0029] In addition, the design of the fasteners often takes into account the need for easy disassembly and maintenance, so that when it is necessary to clean or replace the slag-blocking structure, the operators can carry out the operation quickly and conveniently, which greatly improves the convenience and efficiency of maintenance work.

[0030] In some examples, the drain outlet of the assembly rack is equipped with a removable cover plate for covering the drain outlet, and the cover plate has an opening larger than the size of the filter holes.

[0031] The drain outlet of the assembly rack is equipped with a removable cover. The main function of the cover is to cover the drain outlet to prevent debris or liquid from falling in directly. Notably, the cover has openings that are intentionally larger than the filter holes. This design allows larger solid debris to pass through the openings in the cover for preliminary filtration, preventing debris from directly clogging the drain outlet or the filtration system, thereby improving overall drainage and filtration efficiency.

[0032] The above design not only simplifies the cleaning process but also enhances the practicality and flexibility of the mounting rack. When larger solid debris needs to be cleaned, users can easily access and handle the accumulated debris by simply removing the cover, without the need for complicated disassembly or additional cleaning tools.

[0033] In some examples, a sealing ring is provided between the drain outlet of the assembly frame and the slag-blocking structure to ensure the airtightness between the assembly frame and the slag-blocking structure.

[0034] The primary purpose of the sealing ring is to ensure a good seal at the connection between the assembly frame and the slag-blocking structure. By installing the sealing ring, leakage of fluid or impurities from the gaps between the assembly frame and the slag-blocking structure can be effectively prevented, thus ensuring the normal operation and stable performance of the entire system.

[0035] Furthermore, the use of sealing rings can reduce friction and wear between the assembly frame and the slag-blocking structure to a certain extent, extending the service life of the equipment. During installation, it is necessary to ensure that the sealing rings are accurately positioned and securely installed to fully exert their sealing function.

[0036] In some examples, the slag baffle structure is a corrosion-resistant metal structure, a plastic structure, or a composite material structure.

[0037] The selection of these materials aims to address the various harsh conditions that slag barriers may encounter during use, such as moisture erosion, chemical corrosion, and physical wear. Corrosion-resistant metals, such as stainless steel or titanium alloys, are widely used due to their excellent rust resistance and high strength, enabling them to maintain structural integrity and stability in environments with prolonged exposure to moisture and chemicals.

[0038] In some examples, a drain pipe connected to the ground passage is provided below the assembly frame, the drain outlet is connected to the drain pipe, and a spiral water guide groove is opened on the inner wall of the drain pipe, which is directly or indirectly connected to the filter hole on the slag-separating structure.

[0039] The inner wall of the aforementioned drainage pipe is designed with spiral-shaped water guiding channels, which are directly or indirectly connected to the filter holes on the slag-separating structure. These channels improve the drainage efficiency within the pipe, allowing solid waste to drain quickly.

[0040] Furthermore, spiral-shaped water guide channels can also be installed on the wall of the filter structure. Depending on the configuration of the filter structure, these channels can be installed on the inner or outer wall. This spiral design helps increase the flow path length of water within the filter structure, thereby enhancing the contact opportunity between impurities in the water and the filter structure, and improving the filtration efficiency. When water carrying impurities passes through the filter structure, it is guided to flow along the spiral water guide channels. During this process, larger impurity particles are blocked by the walls of the spiral water guide channels and gradually deposited, while smaller impurity particles may be further guided to the filter holes of the filter structure for interception.

[0051] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and examples. It should be understood that the specific examples described herein are merely illustrative and not intended to limit the scope of this application.

[0052] To solve the above technical problems, please refer to Figures 1-5 As shown, the first aspect of this application proposes a pre-embedded trench slag-separating floor drain, which can achieve efficient drainage and effectively solve the problem of solid residue blockage.

[0053] Reference Figures 1-3As shown, in some examples, the pre-embedded trench drain with slag separation is installed in a predetermined area on the ground, and a trench channel is provided in the predetermined area. The pre-embedded trench drain with slag separation includes:

[0054] The assembly frame 100 has a drain outlet 110 in the middle. The assembly frame 100 is at least partially fixed to the inner wall of the underground passageway. Before the floor is tiled, the assembly frame 100 is at least partially embedded in the corresponding area of ​​the underground passageway. The embedded part of the assembly frame 100 is the embedded part 120.

[0055] The slag-blocking structure 200 is connected to the assembly frame 100. The slag-blocking structure 200 seals the drain outlet 110. The outer circumferential surface of the slag-blocking structure 200 is spaced apart from the inner wall of the underground passage.

[0056] The slag-separating structure 200 has filter holes on its bottom and sides, which allow it to intercept solid residues.

[0057] The pre-embedded trench drain in the above structure is installed in a specific pre-designated area on the ground. Within the pre-designated area, a drainage channel is specially excavated for drainage.

[0058] The pre-embedded trench drain with slag trap mainly consists of two parts: an assembly frame 100 and a slag trap structure 200. The assembly frame 100 serves as the main structure, with a drain outlet 110 in its center for water discharge. Before tiling the floor, at least a portion of the assembly frame 100 needs to be pre-embedded in the corresponding position of the drain channel to ensure a secure connection. The fixed connection portion of the assembly frame 100 fits tightly against the inner wall of the drain channel, enhancing overall stability and sealing.

[0059] The slag-blocking structure 200 is connected to the mounting frame 100 and seals the area where the drain outlet 110 is located, serving to intercept solid residue. The outer periphery of the slag-blocking structure 200 maintains a certain distance from the inner wall of the drainage channel, thus not obstructing water flow while effectively isolating impurities. Specifically, filter holes are cleverly designed into the bottom and sides of the slag-blocking structure 200. These filter holes allow water to flow smoothly while simultaneously intercepting solid residue inside the slag-blocking structure 200, preventing it from entering the drainage system and causing blockages. In this structure, even if solid residue clogs the bottom filter holes, drainage can still be achieved through the side filter holes, realizing an efficient and stable drainage function.

[0060] In this way, the pre-buried trench drain not only achieves efficient drainage but also effectively solves the problem of solid residue blockage, providing a more reliable and convenient drainage solution for various application scenarios.

[0061] In some examples, the slag-filtering structure 200 is prismatic in shape and includes a bottom or top surface and multiple side surfaces. Filter holes are provided on the bottom or top surface and at least one side surface of the slag-filtering structure 200.

[0062] Alternatively, the slag-separating structure 200 may be cylindrical in shape, and may include a bottom or top surface and a peripheral surface, with filter holes provided on both the bottom or top surface and the peripheral surface.

[0063] The sludge-filtering structure 200 in the above structure employs a specific shape to achieve efficient drainage. Specifically, the sludge-filtering structure 200 may be prismatic, consisting of a bottom or top surface and multiple side surfaces, with filter holes evenly distributed on the bottom or top surface and at least one side surface. This design ensures that even if the bottom filter holes are at risk of clogging due to solid residue, water can still flow smoothly through the side filter holes. The shape of the sludge-filtering structure 200 can be a triangular prism, square prism, pentagonal prism, hexagonal prism, etc.

[0064] The sludge-filtering structure 200 may also be designed as a cylinder, comprising a bottom or top surface and surrounding peripheral surfaces, both of which are provided with filter holes. This design also aims to prevent clogging of the bottom filter holes and maintain stable drainage efficiency through the filter holes on the peripheral surfaces.

[0065] In summary, regardless of whether it is a prismatic or cylindrical design, the slag-separating structure 200 can effectively address the clogging challenges that solid residues may cause by opening filter holes on multiple sides, thereby achieving efficient and stable drainage performance.

[0066] Reference Figures 1-3 As shown, in some examples, the slag-separating structure 200 is in the shape of a quadrangular prism. The slag-separating structure 200 includes a bottom surface or top surface and four sides. Multiple filter holes are provided on the bottom surface or top surface and the four sides of the slag-separating structure 200. The bottom surface or top surface with filter holes and the four sides cooperate to form a five-sided drainage filtration structure.

[0067] In the aforementioned structure, the slag-separating structure 200 takes the form of a quadrangular prism, consisting of a bottom or top surface and four sides. Multiple filter holes are distributed on the bottom or top surface and the four sides of this slag-separating structure 200. These bottom or top surfaces with filter holes cooperate with the four sides to form a five-sided drainage filtration structure.

[0068] The five-sided water filtration structure described above is designed to effectively intercept and filter impurities and particulate matter in the water, ensuring clean and unobstructed water flow. The bottom or top surface serves as a support structure, with evenly distributed filter holes, guaranteeing filtration efficiency while preventing clogging due to excessive local pressure. The four sides guide the water flow and increase the filtration area, allowing the water to make more thorough contact with the filter holes as it passes through the filter structure 200, thereby further enhancing the filtration effect.

[0069] To further enhance the practicality and durability of the filter structure 200, high-strength, corrosion-resistant materials, such as stainless steel or special alloys, can be used in its manufacturing process to ensure long-term stable operation of the filter structure 200 in various harsh environments. Simultaneously, the size and shape of the filter holes can be adjusted according to actual needs to adapt to different water qualities and filtration precision requirements.

[0070] In addition, for ease of maintenance and cleaning, the design of the filter structure 200 can also be detachable or flip-up, allowing users to easily clean or replace the filter structure 200, thereby extending its service life and ensuring the continuous and stable filtration effect.

[0071] This five-sided water filtration structure with its slag-separating design not only improves filtration efficiency but also enhances practicality and durability, making it an innovative technology in the field of water treatment.

[0072] The mounting frame 100 can be configured as a stainless steel frame pre-embedded in the trench structure. The five-sided drainage filter structure consists of a top and four sides forming a fence structure, allowing water to flow into the drainage pipe 300 from five directions: top, front, back, left, and right, through the gaps in the grid, while simultaneously intercepting solid waste.

[0073] The stainless steel frame can be fixed in the trench by concrete pouring or masonry structure, and anchors can be provided on the edges of the frame as needed.

[0074] The spacing between the bars in the five-sided drainage filter structure is 5~15mm. The five-sided drainage filter structure can be integrally formed from 304 or 316 stainless steel.

[0075] A retractable fine-mesh filter basket can be added below the five-sided drainage filter structure as needed. The mesh diameter of the fine-mesh filter basket can be 0.5~3mm. The fine-mesh filter basket can be movably connected to the frame via a sliding rail structure, and a pull handle is provided at the front end of the basket.

[0076] The bottom of the assembly frame 100 can be connected to a grease separation chamber, which has an oil drain port at the top and a drain pipe interface at the bottom.

[0077] The five-sided drainage filtration structure has an openable cover plate 400 at the top, which is connected by hinges or buckles. The bottom of the trench forms a slope structure around the pre-buried trench drain, with an inclination angle of ≥3°, which can better guide the water flow.

[0078] At least one side of the five-sided drainage filter structure can employ a detachable baffle structure, which can be secured using quick-release bolts. The stainless steel frame can be made of 904L stainless steel or a nickel-based alloy. The filter holes in the five-sided drainage filter structure can be elongated holes to form grids, and the surface of the grids is inlaid with wear-resistant ceramic blocks.

[0079] The assembly frame 100 and the slag-separating structure 200 can adopt a modular interface design, and the slag-separating structure 200 can be detached and installed by locking screws.

[0080] A liquid level sensor 500 can also be installed inside the pre-embedded trench drain with slag separation. Specifically, it can be installed 10-20cm above the slag separation structure 200, and an audible and visual alarm can be installed to trigger an alarm in case of abnormality. Abnormality includes fluid submerging the liquid level sensor 500 due to blockage, or the liquid level sensor 500 detecting that the fluid level is higher than a preset height.

[0081] The outer wall of the assembly frame 100 can be covered with an insulation layer as needed, which can be made of polyurethane foam or rock wool. The insulation layer can be embedded with electric heating wires and equipped with a temperature control switch. The top height of the five-sided drainage filtration structure is 20-50mm lower than the upper edge of the trench.

[0082] Reference Figure 3 As shown, in some examples, a separable filter basket 210 is added to the inner or outer side of the slag-separating structure 200. Solid residues inside the slag-separating structure 200 are intercepted in the filter basket 210, and the filter basket 210 can transfer and clean the solid residues inside the slag-separating structure 200 by separating it from the slag-separating structure 200.

[0083] A removable filter basket 210 is added inside the aforementioned grease trap structure 200. The main function of the filter basket 210 is to intercept and collect solid residues within the grease trap structure 200. When it is necessary to clean these solid residues, the residues can be easily transferred and cleaned by simply separating the filter basket 210 from the grease trap structure 200, thereby effectively maintaining the cleanliness and unobstructed flow of the grease trap structure 200.

[0084] Furthermore, this design not only improves the ease of cleaning solid residues but also enhances the overall efficiency and service life of the filter structure 200. The separable nature of the filter basket 210 means that residue cleaning can be completed quickly without completely disassembling the filter structure 200, greatly saving time and labor costs.

[0085] Furthermore, the material and structural design of the filter basket 210 have been carefully considered to ensure its ability to withstand physical and chemical stresses in various working environments. For example, it may be made of corrosion-resistant, high-strength materials to resist wear and corrosion that may be caused by solid residues. At the same time, the pore size of the filter basket 210 has also been precisely calculated to ensure effective interception of solid residues without affecting the normal flow of fluid.

[0086] To further improve cleaning efficiency, the filter basket 210 may also be equipped with a structure that facilitates gripping or hoisting, such as a handle or lifting ring. These designs make it easier and safer for operators to clean the filter basket 210.

[0087] In summary, by adding a detachable filter basket 210, the slag-separating structure 200 achieves significant optimization in the interception and removal of solid residues. This design not only improves operational efficiency but also reduces maintenance costs, providing a more reliable and efficient slag-separating solution for various industrial and commercial applications.

[0088] Both the filter basket 210 and the slag-separating structure 200 are provided with perforated structures. These components can be configured to move relative to each other, either by rotation or sliding. A locking structure can be provided to lock the adjusted position. The relative movement of the filter basket 210 and the slag-separating structure 200 allows adjustment of the size of the overlapping perforated structure, thereby regulating the filtration flow rate. Adjustment factors include the size and arrangement of the corresponding perforations in the filter basket 210 and the slag-separating structure 200, the fitting gap between them, and the mode of movement between them, which can be set according to specific needs.

[0089] Furthermore, the size and arrangement of the mesh openings of the filter basket 210 and the filter holes of the slag-separating structure 200 can be set to be the same. At this time, the filter flow rate can be adjusted more precisely by moving the mesh openings of the filter basket 210 and the slag-separating structure 200 relative to each other.

[0090] Reference Figure 4 and Figure 5 As shown, in some examples, the slag-blocking structure 200 is detachably connected to the assembly frame 100. Alternatively, the slag-blocking structure 200 is integrally formed with the assembly frame 100.

[0091] In this application, the slag-separating structure 200 and the assembly frame 100 are connected in a detachable manner, facilitating disassembly and cleaning. Alternatively, the slag-separating structure 200 can be integrated with the assembly frame 100 and cannot be separated, depending on the requirements.

[0092] Furthermore, the specific connection method between the slag-separating structure 200 and the assembly frame 100 can be flexibly selected according to actual needs. For example, a detachable connection can be achieved using fasteners such as bolts and clips, allowing users to quickly assemble and disassemble the slag-separating structure 200 as needed. An integrated design, on the other hand, may use processes such as injection molding or welding to firmly combine the slag-separating structure 200 and the assembly frame 100 together, thereby improving overall stability and durability.

[0093] In practical applications, the choice of connection method requires comprehensive consideration of factors such as the usage frequency of the slag-separating structure 200, cleaning requirements, cost budget, and the material and structure of the assembly rack 100. Through reasonable design and selection, the slag-separating structure 200 can be ensured to operate stably and reliably on the assembly rack 100, while simultaneously meeting the user's actual needs.

[0094] Reference Figure 4 and Figure 5 As shown, in some examples, the pre-embedded trench drain with slag separation also includes at least one fastener 220, and the slag separation structure 200 is connected to the mounting frame 100 via the fastener 220.

[0095] In the aforementioned structure, the fastener 220 is responsible for tightly connecting the slag-separating structure 200 to the assembly frame 100, ensuring the stability and reliability of the entire floor drain system. This connection method not only effectively improves the installation efficiency of the floor drain but also further enhances its ability to withstand various external forces during use, such as water flow impact and foot traffic, thereby significantly extending the service life of the floor drain.

[0096] In addition, the design of the fastener 220 often takes into account the need for easy disassembly and maintenance, so that when it is necessary to clean or replace the slag-blocking structure 200, the operator can carry out the operation quickly and conveniently, which greatly improves the convenience and efficiency of maintenance work.

[0097] It is worth noting that the fastener 220 needs to have good corrosion resistance and strength to adapt to the harsh conditions that may exist in the trench environment, such as moisture, acid and alkali, and ensure the long-term stable operation of the floor drain system.

[0098] In summary, the introduction of the fixing component 220 in the pre-embedded trench slag-separating floor drain not only enhances its structural stability but also improves the convenience of installation and maintenance, making it an important and indispensable part of floor drain design.

[0099] The fastener 220 includes at least one of bolts, magnets, rivets, and pins. Each of these fasteners 220 has a unique function and purpose, and can be selected and combined according to different application scenarios and needs.

[0100] Bolts are typically used in applications requiring high-strength connections and detachability, achieving a fastening effect through tightening the threads. Magnets, on the other hand, are suitable for scenarios requiring the attraction or fixation of magnetic materials, achieving the purpose of fixation through magnetic force.

[0101] Rivets are mainly used for components that require permanent connections and a certain level of strength, using riveting to securely connect two or more components together. Pins, on the other hand, are commonly used in simple locking or fixing devices, using insertion and removal to secure or unlock components.

[0102] In practical applications, the type and specifications of these fasteners 220 can be reasonably selected based on specific fixing requirements, working environment, and material characteristics to ensure the reliability and stability of the connection.

[0103] In some examples, a gap is provided between the drain outlet 110 of the assembly rack 100 and the inner wall of the ground passage to allow water to flow through while intercepting solid residue.

[0104] Water flows freely through this gap, ensuring efficient drainage. Solid debris, such as food scraps and hair, is larger and is blocked by the gap, remaining on the assembly rack 100 or in the drainage channel, thus preventing it from entering the sewer system and avoiding the risk of sewer blockage.

[0105] To further enhance the interception effect, at least one layer of filter screen or grille can be added to the assembly rack 100. These structures can further block fine solid particles, ensuring that only clean water flows through the gaps into the sewer. At the same time, regularly cleaning solid residue from the assembly rack 100 and the underground drainage channels is also an important measure to keep the drainage system unobstructed.

[0106] In summary, by rationally designing the gap between the drain outlet 110 of the assembly frame 100 and the bottom of the underground passage, and combining it with other auxiliary structures, the separation of water flow and solid residue can be effectively achieved, ensuring the normal operation of the drainage system.

[0107] In some examples, the drain 110 of the assembly frame 100 is provided with a removable cover plate 400 for covering the drain 110, and the cover plate 400 is provided with an opening larger than the size of the filter hole.

[0108] The drain outlet 110 of the mounting bracket 100 is equipped with a removable cover 400. The main function of the cover 400 is to cover the drain outlet 110 to prevent debris or liquid from falling directly in. Notably, the cover 400 has openings that are intentionally larger than the filter holes. This design allows larger solid debris to undergo preliminary filtration through the openings in the cover 400, preventing debris from directly clogging the drain outlet 110 or the filtration system, thereby improving overall drainage and filtration efficiency.

[0109] The above design not only simplifies the cleaning process but also enhances the practicality and flexibility of the mounting rack 100. When larger solid debris needs to be cleaned, users can easily access and handle the accumulated debris by simply removing the cover plate 400, without the need for complicated disassembly or additional cleaning tools.

[0110] Furthermore, the detachable nature of the cover 400 allows users to flexibly change or adjust the size and shape of the opening to accommodate different types of solid debris or specific filtration requirements. This modular design not only enhances the adaptability of the mounting frame 100 but also helps improve filtration efficiency, ensuring the drainage system remains unobstructed at all times.

[0111] By installing a removable cover plate 400 with a specific opening size at the drain outlet 110, the assembly rack 100 not only effectively solves the problem of solid residue clogging, but also improves cleaning efficiency and the overall performance of the system, bringing users a more convenient and efficient user experience.

[0112] In some examples, a sealing ring is provided between the drain outlet 110 of the assembly frame 100 and the slag-separating structure 200 to ensure the sealing between the assembly frame 100 and the slag-separating structure 200.

[0113] The main purpose of the sealing ring is to ensure good sealing performance at the connection between the assembly frame 100 and the slag-separating structure 200. By installing the sealing ring, fluid or impurities can be effectively prevented from leaking out from the gap between the assembly frame 100 and the slag-separating structure 200, thereby ensuring the normal operation and stable performance of the entire system.

[0114] Furthermore, the use of sealing rings can reduce friction and wear between the assembly frame 100 and the slag-blocking structure 200 to a certain extent, extending the service life of the equipment. During installation, it is necessary to ensure that the sealing rings are accurately positioned and securely installed to fully exert their sealing function.

[0115] Meanwhile, to maintain the long-term effectiveness of the sealing ring, it is necessary to inspect and replace it regularly to avoid a decline in sealing performance due to aging or damage. In summary, the application of the sealing ring between the assembly frame 100 and the slag-separating structure 200 is of great significance for ensuring the system's sealing performance and stability.

[0116] In some examples, the filter pores of the slag-blocking structure 200 are designed to intercept solid residues larger than a certain size while allowing water to pass through.

[0117] The filter hole size of the aforementioned slag-blocking structure 200 ensures that it can effectively intercept solid residues larger than a certain value, while allowing water to flow smoothly through.

[0118] This design aims to balance filtration efficiency and fluid throughput, preventing larger impurities from entering the downstream system while maintaining good hydrodynamic performance. Through precise calculation and optimization of pore size, the filter structure 200 can operate stably under various conditions, playing a crucial role in fields such as wastewater treatment, food processing, and chemical production. Furthermore, considering the varying filtration precision requirements of different applications, the filter pore size of the filter structure 200 can be customized to achieve optimal filtration performance and economic benefits.

[0119] In some examples, the slag baffle structure 200 is a corrosion-resistant metal, plastic, or composite material structure to ensure its durability in humid environments.

[0120] The materials chosen are designed to withstand the harsh conditions that the slag barrier structure 200 may encounter during use, such as moisture erosion, chemical corrosion, and physical wear. Corrosion-resistant metals, such as stainless steel or titanium alloys, are widely used due to their excellent rust resistance and high strength, enabling them to maintain structural integrity and stability in environments with prolonged exposure to moisture and chemicals.

[0121] Plastic materials, especially engineering plastics designed for humid environments, such as polypropylene (PP), polyvinyl chloride (PVC), or polytetrafluoroethylene (PTFE), have excellent chemical resistance and good insulation properties, while being relatively inexpensive and easy to process and mold, making them suitable for manufacturing complex shapes and pressure-resistant slag-blocking structures.

[0122] Composite materials, by combining two or more materials with different properties, can integrate the advantages of each component, such as high strength, light weight, and good corrosion resistance. For example, glass fiber reinforced plastic (GFRP) or carbon fiber reinforced plastic (CFRP) combines the corrosion resistance of plastics with the high strength of fiber materials, making them an ideal choice for high-performance slag barriers, especially suitable for applications with strict weight requirements.

[0123] Whether it is metal, plastic or composite material, the selection is based on the specific application scenario, cost budget and specific requirements for durability and performance of the slag barrier structure 200, so as to ensure that the slag barrier structure 200 can operate stably for a long time in various humid environments.

[0124] In some examples, a drain pipe 300 connected to a ground passage is provided below the assembly frame 100, and the drain outlet 110 is connected to the drain pipe 300. A spiral water guide groove is provided on the inner wall of the drain pipe 300, and the water guide groove is directly or indirectly connected to the filter hole on the slag separation structure 200.

[0125] The inner wall of the aforementioned drain pipe 300 is designed with spiral-shaped water guiding channels, which are directly or indirectly connected to the filter holes on the slag-separating structure 200. These water guiding channels improve the drainage efficiency within the drain pipe 300, allowing solid residues to drain quickly.

[0126] Furthermore, spiral-shaped water guide channels can also be set on the wall surface of the filter structure 200, specifically on the inner or outer wall depending on the configuration of the filter structure 200. This spiral-shaped water guide channel design helps increase the flow path length of water within the filter structure 200, thereby enhancing the contact opportunity between impurities in the water and the filter structure 200, and improving the filtration efficiency of impurities. When water carrying impurities passes through the filter structure 200, it is guided to flow along the spiral water guide channels. During this process, larger impurity particles are blocked by the wall surface of the spiral water guide channels and gradually deposited, while smaller impurity particles may be further guided to the filter holes of the filter structure 200 for interception during the flow.

[0127] Furthermore, to optimize filtration, the cross-sectional shape and dimensions of the water guide channel can be designed to ensure good impurity capture capabilities at different water flow velocities. Simultaneously, the size and distribution of the filter holes on the sludge-filtering structure 200 can be adjusted according to actual needs to achieve precise filtration of impurities of different sizes.

[0128] The connection between the drain pipe 300 and the filtration structure 200 may be sealed to prevent unfiltered water from bypassing the filtration structure 200 and entering subsequent treatment stages. This design not only improves the overall filtration efficiency of the system but also helps maintain the cleanliness and normal operation of subsequent water treatment equipment.

[0129] By combining the drain pipe 300, the spiral guide channel, and the slag-separating structure 200, impurities can be effectively removed from the water flow, providing a clean water source for subsequent water treatment processes.

[0130] The assembly rack 100 and slag-separating structure 200 of this application have several advantages. First, they are both easy to install and disassemble, greatly facilitating daily maintenance and component replacement. The drain outlet 110 of the assembly rack 100 can be specially designed with an inclined angle to ensure smooth water flow and avoid water accumulation. At the same time, the connection between the drain outlet 110 and the underground passage is equipped with an anti-slip structure to effectively prevent the assembly rack 100 from shifting due to water flow impact.

[0131] In terms of strength and stability, both the mounting frame 100 and the slag-separating structure 200 are meticulously designed to withstand various loads in daily use, ensuring long-term reliability. Furthermore, their design takes into account the ease of replacement or cleaning without damaging the floor tiles, reducing the environmental impact of construction.

[0132] To meet the needs of different water flow rates, the drain outlet 110 of the mounting frame 100 is designed with an adjustable flow rate, which users can adjust according to actual conditions. Meanwhile, both the mounting frame 100 and the sludge-proof structure 200 have odor-proof functions, effectively preventing sewer odors from overflowing and maintaining fresh indoor air.

[0133] In terms of adaptability, their design fully considers the characteristics of different ground materials, ensuring stable installation on various surfaces. Furthermore, the assembly frame 100 and the slag-blocking structure 200 generate extremely low noise during operation, providing users with a quieter operating environment.

[0134] Finally, they are all easy to clean, reducing the labor intensity of maintenance and bringing a more convenient user experience.

[0135] Furthermore, the assembly rack 100 and the slag-separating structure 200 can also incorporate intelligent elements. For example, the assembly rack 100 is equipped with an intelligent flow monitoring system that can monitor flow changes in real time and automatically alarm when the flow is abnormal, effectively preventing flooding.

[0136] To further enhance the user experience, the design of the assembly rack 100 and the slag-separating structure 200 emphasizes user-friendly details. The slag-separating structure 200 uses a transparent material, allowing users to intuitively understand the accumulation of impurities and clean them in a timely manner.

[0137] In terms of environmental protection and energy conservation, the assembly rack 100 and the slag-separating structure 200 have also made positive contributions. They adopt energy-saving and environmentally friendly materials and processes, reducing energy consumption and emissions during the production process. At the same time, the optimized drainage design reduces water waste and contributes to sustainable development.

[0138] The assembly rack 100 and the slag-separating structure 200 not only possess excellent practicality and durability, but also incorporate intelligent, user-friendly, and environmentally friendly energy-saving design concepts, providing users with a more convenient, efficient, and comfortable user experience. They will become the preferred solutions for future home decoration and public facility construction, making a positive contribution to promoting social progress and environmental protection.
