Description

Technical Field

[0001] This utility model belongs to the field of energy-saving renovation technology for heating furnaces, and particularly relates to a firmly installed energy-saving element for heating furnaces and a heating furnace. Background Technology

[0002] Most energy-saving components are installed at the top of the furnace. During installation, high-temperature adhesives are used to directly fix the bonding surface to ensure a firm bond between the energy-saving component and the furnace top. However, directly fixing the bonding surface with high-temperature adhesives often results in insufficient adhesion between the bottom of the energy-saving component and the furnace surface due to factors such as gravity and vibration during construction.

[0003] In the renovation of thermal equipment in industrial kilns, the fixing process of top-mounted energy-saving components faces the following technical bottlenecks: The currently widely used single-layer interface bonding technology of high-temperature adhesive on the furnace top can achieve the initial bonding between the component and the top wall area of ​​the furnace, but under actual working conditions, it is prone to the following structural failures due to the coupling effect of gravity load and construction dynamic stress.

[0004] The existing solution is to set a mounting hole at the top center of the energy-saving element, and to install a fastening screw in the mounting hole. One end of the fastening screw passes through the mounting hole along the inner wall of the energy-saving element and is driven into the top of the furnace to achieve the connection between the energy-saving element and the furnace. However, the fastening screw is prone to breakage along the mounting hole during the screwing process, which reduces the reliability of the energy-saving element. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides a securely installed energy-saving element and a heating furnace. The energy-saving element is integrated with the fastening nail, which better restricts the freedom of the energy-saving element before the bonding surface between the energy-saving element and the furnace chamber solidifies naturally, thereby improving the installation reliability of the energy-saving element, ensuring the service life of the energy-saving element, and maintaining the continuous energy-saving efficiency of the heating furnace.

[0006] In order to achieve the purpose of this utility model, the following solution is proposed:

[0007] A securely installed energy-saving element for a heating furnace includes a main element, a cavity at the lower end of the main element, a receiving groove at the upper end of the main element, a fastening pin vertically arranged in the receiving groove, and the fastening pin and the main element are integrally formed, with secondary holes on both sides of the fastening pin.

[0008] Furthermore, a fastening spring is fitted onto the fastening pin.

[0009] Furthermore, a washer is provided at the upper end of the fastening pin, and the washer is located at the upper end of the fastening spring.

[0010] Furthermore, the main component has an inverted frustum structure.

[0011] Furthermore, the cavity connects to the small end of the main component.

[0012] A heating furnace includes a furnace top with a central hole for installing energy-saving components.

[0013] The beneficial effects of this utility model are as follows:

[0014] The top surface of the energy-saving element is roughened by the presence of receiving grooves and secondary holes, and the one-time molding structure for fixing the energy-saving element is rationally adopted. This increases the pressure and fixing effect between the high-temperature adhesive and the furnace substrate, allowing the high-temperature adhesive to better penetrate into the recesses or pores on the substrate surface. After high-temperature curing, it plays an embedding role, which can firmly bond the energy-saving element to the furnace substrate for a long time. This improves the installation reliability of the energy-saving element, ensures the service life of the energy-saving element, and maintains the continuous energy-saving efficiency of the heating furnace.

[0019] 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.

[0020] Example 1

[0021] like Figures 1-2 As shown, this embodiment provides a securely installed energy-saving element for a heating furnace, including a main element 1, which has an inverted frustum structure. A cavity 2 is recessed at the lower end of the main element 1, communicating with the smaller end of the main element 1; that is, the cavity 2 is formed by the recess from the smaller end of the main element 1. A receiving groove 11 is provided at the upper end of the main element 1. The receiving groove 11 has a rectangular cross-section, and a fastening pin 12 is vertically arranged within the receiving groove 11. Secondary holes 13 are provided on both sides of the fastening pin 12, thereby increasing the roughness of the top surface of the main element 1.

[0022] The axis of the fastening nail 12 is coaxial with the axis of the main component 1, and the fastening nail 12 and the main component 1 are integrally formed. This avoids the need for the traditional method of passing the fastening nail 12 through the center hole at the top of the main component 1, adding a washer through the center hole at the top of the component to be installed, and then tightening the fastening nail. This eliminates the need for a center hole that easily causes the main component 1 to break through the center, making the structure of the main component 1 more reasonable and compact. The compressive strength of the main component 1 is improved, and the installation and bonding of the main component 1 can be completed in one step. It can better restrict the degree of freedom of solidification of the bonding surface between the main component 1 and the furnace, and better play the dual role of fixing and pressurizing.

[0023] Specifically, a fastening spring 3 and a washer 4 are fitted on the upper end of the fastening nail 12, with the fastening spring 3 located below the washer 4.

[0024] Example 2

[0025] This embodiment provides a heating furnace for installing the energy-saving element described in Embodiment 1. The heating furnace includes a furnace top 5, and the furnace top 5 is provided with a central hole 51. The diameter of the central hole 51 matches the diameter of the gasket 4, for installing and accommodating the fastening nail 12, the gasket 4, and the fastening spring 3.

[0026] Specific installation process:

[0027] High-temperature adhesive is filled and compacted into the receiving groove 11 and secondary hole 13 of the main component 1. High-temperature adhesive meeting process requirements is also fully applied to the top surface of the main component 1 and compacted into the central hole 51 of the furnace top 5. The fastening spring 3 and washer 4 are then sequentially fitted onto the fastening nail 12, aligning the upper end of the fastening nail 12 with the corresponding central hole 51 on the furnace top 5. The upper end of the fastening nail 12 is then vertically inserted upwards along the central hole 51, pressing against the main component 1 and squeezing it. The main component 1 is then tightened according to the thread direction of the fastening nail 12. The adhesive on the top surface of the main component 1 is then smoothly applied to the hinge point between the furnace top and the surface of the main component 1. This allows the high-temperature adhesive to better penetrate into the recesses or pores of the substrate surface. After high-temperature curing, it acts as a "rod, nail, hook"-like embedding mechanism, firmly bonding the energy-saving element to the furnace substrate for a long period. This improves the installation reliability of the energy-saving element, ensures its service life, and maintains the continuous energy-saving efficiency of the heating furnace.

[0028] The above description is merely a preferred embodiment of this utility model and does not imply its uniqueness or limitation. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
