Description

Technical Field

[0001] This utility model belongs to the technical field of energy-saving component modification for heating furnaces, and particularly relates to an energy-saving component for heating furnaces and a furnace top structure. Background Technology

[0002] In industrial furnace systems, energy-saving components are mainly located in the top area of ​​the furnace. Their fixing process employs a composite method combining high-temperature adhesive coating at the contact interface with room-temperature anchoring using a single screw at the bottom centerline, creating a dual fixing mechanism to ensure interface bonding strength. Specifically, a gradient high-temperature adhesive layer is applied to the bonding interface, while a single-point mechanical anchoring device positioned along the bottom centerline simultaneously achieves stress even distribution under room-temperature conditions, forming a composite fixing system of adhesive-mechanical interlocking.

[0003] However, when using high-temperature adhesives for fixing and bonding, the initial adhesion of the bonding surface is low during the natural solidification period at room temperature, and due to vibration and downward force during construction, the bottom of the energy-saving element and the inner wall of the furnace are prone to displacement, pores and delamination, resulting in low adhesion of the bonding surface and a large number of energy-saving elements falling off, which seriously affects the effectiveness of energy-saving renovation. Secondly, after using a single fastening screw to limit the installation through the center of the bottom of the component, the bonding plane cannot be well defined at a single point, resulting in insufficient adhesion between the bottom of the component and the bonding surface of the furnace wall. This makes it difficult to achieve the dual functions of pressurization and fixation, and the component may even fall off before reaching the process temperature, making it difficult to realize the continuous energy-saving transformation effect. Utility Model Content

[0004] To address the shortcomings of the existing technology, this utility model provides an energy-saving element and furnace top structure for a heating furnace, which is not only easy to install but also not easy to fall off, thus ensuring the energy-saving effect of the heating furnace renovation.

[0005] In order to achieve the purpose of this utility model, the following solution is proposed: An energy-saving element for a heating furnace includes a main body with a cavity recessed at its lower end, a heat-absorbing block covering the outer wall of the main body, a groove at the outer end of the heat-absorbing block, a connecting column at the top of the main body, support blocks on both sides of the upper end of the connecting column, a mounting hole coaxially provided inside the connecting column, and a spring provided inside the mounting hole.

[0006] Furthermore, the main body has an inverted frustum structure.

[0007] Furthermore, the main body is formed using a casting mold.

[0008] Furthermore, the entire body is coated with a high-temperature glaze.

[0009] Furthermore, the bottom outer end of the heat absorber block is provided with a first hole of inverted conical shape, and the lower outer periphery of the first hole is provided with a second hole arranged in a circumferential array.

[0010] A furnace top structure for installing the energy-saving element of the furnace is provided. The furnace top has a T-shaped mounting hole, and the vertical part of the mounting hole has a sliding groove for the support block to pass through when installing the energy-saving element.

[0011] The beneficial effects of this utility model are as follows: The mounting hole on the top of the heating furnace is designed as a T-shaped structure. Symmetrical grooves are set in the vertical part of the mounting hole. A connecting column is integrally formed on the upper part of the main body of the energy-saving element of the heating furnace. A receiving hole is set coaxially in the connecting column. A spring is installed in the receiving hole, with the upper end of the spring extending a certain length beyond the upper end of the connecting column. Support blocks are set on both sides of the upper end of the connecting column that protrude outward. During installation, the support blocks enter the horizontal part of the mounting hole through the grooves, and the upper end of the spring presses against the upper end of the horizontal part of the mounting hole, thereby compressing the spring. Under the action of the spring compression, the support blocks are pressed tightly into the horizontal part of the mounting hole, so that the energy-saving element of the heating furnace is installed firmly, and the installation is convenient and simple to operate.

[0021] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1 like Figures 1-3 As shown, this embodiment provides an energy-saving element for a heating furnace, including a main body 1. The main body 1 has an inverted frustum structure. A cavity 2 is provided at the lower end of the main body 1, which is recessed upward and inward. A heat-absorbing block 3 is provided on the outer wall of the main body 1. A connecting column 11 is coaxially provided at the upper end of the main body 1. Support blocks 12 are symmetrically provided on both sides of the upper end of the connecting column 11. The support blocks 12 protrude outward along the radial direction of the connecting column 11.

[0023] The connecting column 11 has a cylindrical receiving hole 13 coaxially arranged inside. A spring 14 is installed inside the receiving hole 13. The upper end of the spring 14 extends vertically upward from the receiving hole 13 for a certain length to abut against the top of the heating furnace during installation.

[0024] The outer end of the heat-absorbing block 3 is provided with a groove 31 to increase the surface area of ​​the heat-absorbing block 3 so as to absorb more heat.

[0025] Preferably, to further concentrate heat, a first hole 32 with an inverted conical structure is provided at the bottom outer end of each heat-absorbing block 3. A second hole 33 is arranged in a circumferential array around the outer periphery of the first hole 32, and the second hole 33 is a circular hole to facilitate processing. The distribution range of the first hole 32 and the second hole 33 on the upper and lower adjacent heat-absorbing blocks 3 is arranged sequentially and alternately in the radial projection of the main body 1, thereby avoiding the heat rays emitted by the first hole 32 and the second hole 33 on the upper heat-absorbing block 3 from acting on the lower heat-absorbing block 3, so that the workpiece is heated better, the heat exchange rate is improved, and fuel consumption is reduced.

[0026] During manufacturing, the main body 1 and the connecting column 11 are formed by casting, and the lower end of the spring 14 is welded to the bottom of the receiving hole 13.

[0027] Preferably, the main body element 1 is coated with a high-temperature glaze to give the main body element 1 high emissivity and high stability, thereby extending the service life of the main body element 1.

[0028] Example 2 like Figures 4-7As shown, this embodiment provides a furnace top structure for installing the furnace energy-saving element described in Embodiment 1. The furnace top 4 is provided with a T-shaped mounting hole 41. The vertical part of the mounting hole 41 is provided with a sliding groove 42. Two sliding grooves 42 are symmetrically arranged. When installing the furnace energy-saving element, the two support blocks 12 are respectively aligned with the sliding grooves 42. Then, the support blocks 12 are vertically upward and passed through the sliding grooves 42. The main body 1 is rotated so that the bottom surface of the support block 12 is located on the surface at the connection between the horizontal and vertical parts of the mounting hole 41. Under the action of the spring 14, the support block 12 is pressed tightly into the mounting hole 41, thereby making the furnace energy-saving element firmly installed, easy to operate, and not easy to fall off. When the furnace energy-saving element needs to be replaced, the support block 12 is rotated to the upper end of the sliding groove 41 and can be easily removed, saving time and effort.
