Description

Technical Field

[0001] This utility model relates to the field of heating tube technology, and in particular to a structure of a scale-resistant high-temperature water temperature controller heating tube. Background Technology

[0002] During the operation of a high-temperature water heater, the heating element, as the core heating component, is prone to scale formation due to the accumulation of impurities and the crystallization of calcium and magnesium ions when it is in long-term contact with the water medium.

[0003] Traditional heating elements are mostly made of ordinary stainless steel, which has high surface tension, making it easy for scale to adhere and difficult to remove. As the scale thickness increases, it not only significantly reduces the heat conduction efficiency of the heating element, leading to decreased temperature control accuracy and increased energy consumption, but may also damage the heating element due to localized overheating, shortening the equipment's lifespan. Simultaneously, traditional heating elements lack targeted filtration structures, allowing large particles (such as silt and pipe debris) and small to medium-sized particles in the water to directly contact the heating element surface, becoming the "core carriers" for scale formation and further exacerbating the scaling problem. Therefore, to address these issues, there is an urgent need to develop a scale-resistant high-temperature water heater heating element structure that uses a detachable filtration mechanism with coarse and fine filtration layers to trap impurities and reduce the basis for scale formation; a metal heat-conducting tube made of duplex stainless steel and coated with a polyetheretherketone nano-coating to reduce scale adhesion; and an external spiral guide groove to enhance water flow scouring force and reduce scale adhesion, while the annular convex band's thermal expansion deformation helps to peel off scale, thereby improving the overall anti-scaling performance. This structure aims to overcome the shortcomings of current practical applications and meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide a scale-resistant high-temperature water heater heating tube structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-temperature water heater heating element structure with anti-scaling features includes a housing, a filter anti-scaling mechanism, a metal heat-conducting pipe, and a sealing ring. A heating wire is installed inside the metal heat-conducting pipe, and magnesium oxide powder is filled in the gap between the metal heat-conducting pipe and the heating wire. A circuit module is installed inside the housing, and the heating wire is electrically connected to the circuit module. The upper end of the metal heat-conducting pipe is inserted into and fixed to the housing. A sealing ring is fixed at the connection between the metal heat-conducting pipe and the housing. A polyether ether ketone (PEEK) nano-coating is sprayed onto the outer side of the metal heat-conducting pipe. A spiral guide groove is provided on the outer side of the metal heat-conducting pipe, and multiple annular protrusions are fixed on the outer side of the metal heat-conducting pipe. The filter anti-scaling mechanism is located outside the metal heat-conducting pipe and is detachably connected to the housing.

[0007] Preferably, the metal heat pipe is made of duplex stainless steel 2507.

[0008] Preferably, the distance between two adjacent annular convex strips is 50mm.

[0009] Preferably, the filter anti-scaling mechanism includes a threaded sleeve, a coarse filter layer, and a fine filter layer. The inner side of the threaded sleeve is provided with an internal thread, and the outer side of the lower half of the housing is provided with an external thread that mates with the threaded sleeve. The coarse filter layer and the fine filter layer are fixed on the lower side of the threaded sleeve, and the fine filter layer is located inside the coarse filter layer.

[0010] Preferably, the coarse filtration layer uses a 120-mesh stainless steel filter screen, and the fine filtration layer uses a 600-mesh stainless steel filter screen.

[0011] The beneficial effects of this utility model are as follows: The anti-scaling high-temperature water heater heating tube structure, during use, intercepts large particles of impurities through a coarse filter layer and small and medium-sized particles through a fine filter layer, thereby reducing the contact between impurity particles and the metal heat-conducting tube, thus reducing scale formation on the surface of the metal heat-conducting tube. The polyether ether ketone nano-coating on the outside of the metal heat-conducting tube has good thermal conductivity and high hydrophobicity, which can reduce scale adhesion. The spiral guide channel guides the water flow to form a spiral vortex, enhancing the scouring force of the water flow on the tube wall and preventing water from stagnating on the tube wall to form a dead water layer, thus reducing scale deposition from a dynamic perspective. During heating, the thermal expansion of the pipe causes slight deformation of the annular convex strip, which can squeeze and peel off the already attached thin scale, preventing continuous scale accumulation. After a period of use, the threaded sleeve can be unscrewed from the casing, and the coarse and fine filter layers can be rinsed and cleaned with high-pressure water. In summary, this utility model uses a detachable filtration mechanism with coarse and fine filtration layers to filter impurities in layers, reducing the basis for scale formation; the metal heat-conducting pipe is made of duplex stainless steel and coated with a polyether ether ketone nano-coating, reducing scale adhesion; the spiral guide groove on the outside of the pipe enhances the water flow scouring force to reduce scale adhesion, and the annular convex strip's thermal expansion deformation plays a role in peeling off scale, thereby improving the overall anti-scaling performance.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Specific implementation examples are given below.

[0019] See Figures 1-3 In this embodiment of the utility model, a heating tube structure for an anti-scaling high-temperature water heater includes a housing 1, a filter anti-scaling mechanism 2, a metal heat-conducting tube 3, and a sealing ring 4. A heating wire is installed inside the metal heat-conducting tube 3, and magnesium oxide powder is filled in the gap between the metal heat-conducting tube 3 and the heating wire. Magnesium oxide powder has good thermal conductivity and high insulation resistance, ensuring safety. A circuit module is installed inside the housing 1, and the heating wire is electrically connected to the circuit module. The upper end of the metal heat-conducting tube 3 is inserted into and fixed to the housing 1. A sealing ring 4 is fixed at the connection between the metal heat-conducting tube 3 and the housing 1 to prevent water leakage. The metal heat-conducting tube 3 is made of duplex stainless steel 2507, which, compared to traditional 304 stainless steel, has a higher temperature resistance (up to 280℃), higher corrosion resistance, and low surface tension, reducing the initial adhesion of scale. The outer side of the metal heat-conducting tube 3 is coated with a polyetheretherketone nano-coating. With good thermal conductivity and high hydrophobicity, it can reduce scale adhesion. The outer side of the metal heat pipe 3 is provided with a spiral guide groove 301, which is at a 30° angle with the pipe axis. This guides the water flow to form a spiral vortex, enhances the scouring force of the water flow on the pipe wall, and prevents the water flow from staying on the pipe wall to form a dead water layer. This reduces scale deposition from a dynamic perspective. Multiple annular convex strips 302 are fixed on the outer side of the metal heat pipe 3. The distance between two adjacent annular convex strips 302 is 50mm. When heated, the thermal expansion of the pipe will cause the annular convex strips 302 to undergo slight deformation, which can squeeze and peel off the thin scale that has already adhered, preventing the scale from continuing to accumulate. The filter anti-scaling mechanism 2 is located on the outer side of the metal heat pipe 3 and is detachably connected to the housing 1. The filter anti-scaling mechanism 2 intercepts impurities in the water, thereby reducing the formation of scale on the surface of the metal heat pipe 3.

[0020] The anti-scaling filter mechanism 2 includes a threaded sleeve 201, a coarse filter layer 202, and a fine filter layer 203. The inner side of the threaded sleeve 201 is provided with an internal thread, and the outer side of the lower half of the housing 1 is provided with an external thread 101 that mates with the threaded sleeve 201. The coarse filter layer 202 and the fine filter layer 203 are fixed on the lower side of the threaded sleeve 201. The fine filter layer 203 is located inside the coarse filter layer 202. The coarse filter layer 202 uses a 120-mesh stainless steel filter screen, and the fine filter layer 203 uses a 600-mesh stainless steel filter screen. The coarse filter layer 202 intercepts large particles of impurities, and the fine filter layer 203 intercepts medium and small particles, thereby reducing the contact between impurity particles and the metal heat pipe 3.

[0021] The casing 1 is equipped with a connector 5 that connects to its internal circuit module. Power is supplied by plugging the connector 5 into an external circuit.

[0022] Working Principle: The anti-scaling high-temperature water heater's heating element structure, during use, uses a coarse filter layer 202 to intercept large particles of impurities, and a fine filter layer 203 to intercept small and medium-sized particles, thereby reducing the contact between impurity particles and the metal heat-conducting pipe 3. This reduces the formation of scale on the surface of the metal heat-conducting pipe 3. The polyetheretherketone nano-coating on the outside of the metal heat-conducting pipe 3 has good thermal conductivity and high hydrophobicity, which can reduce scale adhesion. The spiral guide groove 301 guides the water flow to form a spiral vortex, enhancing the scouring force of the water flow on the pipe wall and preventing water from stagnating on the pipe wall to form a dead water layer, thus reducing scale deposition from a dynamic perspective. During heating, the thermal expansion of the pipe causes the annular convex strip 302 to undergo slight deformation, which can squeeze and peel off the thin layer of scale that has already adhered, preventing the continuous accumulation of scale. After a period of use, the threaded sleeve 201 can be unscrewed from the housing 1, and then the coarse filter layer 202 and the fine filter layer 203 can be rinsed and cleaned using high-pressure water.

[0023] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
