Description

Technical Field

[0001] This utility model relates to the field of fluid heating technology, specifically to an improved electric boiler electric heating rod assembly and an electric boiler heating system using the same. Background Technology

[0002] An electric boiler is a boiler equipment that uses electricity as its energy source and converts it into heat energy, which is then converted by the boiler to output steam, high-temperature water, or organic heat carrier with a certain amount of heat energy.

[0003] Its structure includes the most basic furnace body. To improve heating efficiency, the furnace body is generally equipped with several sub-furnace bodies, and each sub-furnace body is equipped with a heating rod group to heat the fluid.

[0004] The design of heating rod assemblies requires a certain degree of structural rigidity to prevent deformation; at the same time, it needs to allow as much space as possible for heat exchange; and it needs to increase fluid flow to prevent scale formation. However, existing heating rod assemblies are unlikely to meet all three requirements simultaneously.

[0005] Therefore, this application improves the existing electric heating rod assembly of electric boilers to provide better heating efficiency. Summary of the Invention

[0006] To address the technical problems existing in the background art, this utility model provides an improved electric boiler electric heating rod assembly and an electric boiler heating system using the same.

[0007] The technical solution of this utility model is as follows:

[0008] The improved electric boiler heating element assembly includes several groups of ring-shaped heating elements installed inside the outer casing. Each heating element has a U-shaped structure. Compared to straight rods, the one-piece molded U-shaped heating elements effectively improve structural rigidity and avoid the problem of easy deformation of traditional straight rods. The front, middle, and rear ends of the heating elements are respectively fitted with full baffles, first half baffles, and second half baffles for fixing the heating elements.

[0009] The baffle is a hollow ring structure with several ring arrays of clamping arcs on the inner wall. The radius of the clamping arcs is the same as the radius of the heating rod, which can accommodate the insertion of the heating rod.

[0010] The first half-baffle and the second half-baffle are respectively arranged at the upper and lower parts of the electric heating rod assembly;

[0011] The heating rod passes through the first half-baffle and / or the second half-baffle and then inserts into the clamping arc of the full baffle.

[0012] In this way, each heating element passes through two baffles before being secured, ensuring it remains stable during operation. Simultaneously, the interior space of the full baffle is empty, and the half-baffle also leaves half a space, facilitating heat exchange between the heating element and the fluid. Furthermore, the two half-baffles arranged vertically prevent unidirectional fluid flow, increasing fluid mobility and thus preventing scale buildup.

[0013] Furthermore, the adjacent clamping arcs of the full baffle are circularly transitioned.

[0014] In a preferred embodiment, the clamping arc of the full baffle is tangent to the adjacent circular arc.

[0015] In one embodiment, both the first half-baffle and the second half-baffle are crescent-shaped plates.

[0016] Alternatively, both the first and second half-baffles can be semi-circular plates arranged vertically, with no interference in the lateral projection, making installation easier.

[0017] In one embodiment, the heating rod is provided in three sets, with three through holes respectively opened on the first half-baffle and the second half-baffle for the heating rod to pass through.

[0018] The heating rod is covered by an outer shell, which is a hollow cylindrical part with detachable sealing plates at both ends. The inner wall of the outer shell is provided with support platforms for connection at corresponding positions of the full baffle, the first half baffle, and the second half baffle, and the support platforms do not interfere with the heating rod.

[0019] During installation, the full baffle, the first half baffle, and the second half baffle are pre-installed on the corresponding support platform. Then, each group of heating rods is passed through and fixed, the junction box is connected, and the sealing plate is closed.

[0020] This utility model also provides an electric boiler heating system, wherein the electric boiler used adopts the above-mentioned electric heating rod group.

[0021] Through the above design, the electric heating rod assembly of this utility model for electric boilers, using a one-piece molded U-shaped heating rod, effectively improves structural rigidity and avoids the problem of easy deformation of traditional straight rods. Each heating rod passes through two baffles before being fixed, ensuring it remains stable during operation. Simultaneously, the interior space of the full baffle is empty, and the half-baffle also leaves half a space, facilitating heat exchange between the heating rod and the fluid. Furthermore, the two upper and lower half-baffles prevent unidirectional fluid flow, increasing fluid fluidity and thus preventing scale formation. Attached Figure Description

[0029] See Figure 2 This embodiment provides an improved electric boiler heating rod assembly, including several groups of ring-arranged heating rods 1 installed inside the outer casing 5. This embodiment uses 3 groups as an example for introduction. Each heating rod 1 has a U-shaped structure. Compared with the straight rod style, the one-piece molded U-shaped heating rod 1 can effectively improve the structural rigidity and avoid the problem of easy deformation of traditional straight rods.

[0030] The front, middle and rear ends of the three sets of heating rods 1 are respectively fitted with a full baffle 2, a first half baffle 3 and a second half baffle 4, which are used to fix the heating rods 1.

[0031] See Figure 2 and Figure 4 As shown, the baffle 2 is a hollow ring structure with six ring-shaped clamping arcs on the inner wall. The radius of the clamping arcs is the same as the radius of the heating rod 1, which can accommodate the insertion of the heating rod 1.

[0032] Furthermore, the adjacent clamping arcs of the full baffle 2 are rounded to facilitate the insertion of the heating rod 1.

[0033] In a preferred embodiment, the clamping arc of the full baffle 2 is tangent to the adjacent circular arc.

[0034] The first half-baffle 3 and the second half-baffle 4 are respectively arranged at the upper and lower parts of the electric heating rod assembly;

[0035] The heating rod 1 passes through the first half-baffle 3 and / or the second half-baffle 4 at both ends and is then inserted into the clamping arc of the full baffle 2.

[0036] In this way, each heating rod 1 passes through two baffles before being fixed in place, ensuring it remains stable during operation. Simultaneously, the interior space of the full baffle 2 is empty, and the half baffle also leaves half a space, facilitating heat exchange between the heating rod 1 and the fluid, which can be water. Furthermore, the two half baffles arranged vertically prevent unidirectional fluid flow; the fluid must change direction at least once before flowing out, increasing fluid flowability and thus preventing scale buildup.

[0037] See Figure 2 and Figure 3 The first half-baffle 3 and the second half-baffle 4 can be crescent-shaped or semi-circular.

[0038] In this embodiment, the first half-baffle 3 and the second half-baffle 4 are shown as semi-circular plates. The two half-baffles are arranged vertically, and there is no interference in the horizontal projection, which facilitates installation.

[0039] Specifically, three through holes are respectively opened on the first half-baffle 3 and the second half-baffle 4 for the heating rod 1 to pass through. Figure 3 The image shown is a rendering of the installation of an electric heating rod.

[0040] See Figure 1 The electric heating rod assembly is installed inside the sub-boiler body of the electric boiler. A shell 5 covers the heating rod 1. The shell 5 is a hollow cylindrical component with detachable sealing plates at both ends. Support platforms 51 for connection are provided on the inner wall of the shell 5 at corresponding positions of the full baffle 2, the first half baffle 3, and the second half baffle 4. These support platforms 51 do not interfere with the heating rod 1. (See [reference]). Figure 4 As shown.

[0041] The radii of the full baffle 2, the first half baffle 3, and the second half baffle 4 are the same as the radius of the outer casing 5. During installation, the full baffle 2 is inserted from the left side and connected to the corresponding support platform 51 with bolts. The first half baffle 3 and the second half baffle 4 are inserted from the right side and connected to the corresponding support platform 51 with bolts. The heating rod 1 is passed through the half baffle and the full baffle 2 from the right side and fixed to the sealing plate on the left side. The junction box is then connected, and the sealing plates on both sides are sealed.

[0042] This utility model also provides an electric boiler heating system, wherein the electric boiler used adopts the above-mentioned electric heating rod group.
