Description

Technical Field

[0001] The utility model relates to the technical field of heating furnaces, in particular to a heating furnace body steel structure. Background Art

[0002] A heating furnace is an industrial equipment used to heat materials to the required temperature. It is widely used in chemical, metallurgical, mechanical, building materials and other industries, mainly used for material drying, smelting, heat treatment and other processes. There are many types and structures of heating furnaces. Depending on the heating method, fuel type, material form and other factors, the design and operation of the heating furnace will also be different.

[0003] During the use of the heating furnace, the heat inside the furnace body is too high, so it will diffuse to the outside of the furnace body, causing the temperature around the furnace body to rise simultaneously, resulting in heat overflow, increasing the energy loss of the heating furnace, and reducing the heating efficiency. In addition, when using the heating furnace, the heating furnace is mostly fixed and welded on a metal base. The main purpose is to enhance the stability of the heating furnace body and avoid the accidental tipping of the furnace body during use. However, after welding the base, the movement of the heating furnace requires cutting and splitting it from the base, which is inconvenient. In order to solve the above problems, while facilitating the use of the heating furnace, it is convenient to provide thermal insulation protection for it, thereby reducing energy loss and improving heating efficiency. It is also convenient to install and fix the heating furnace body, and it is also convenient to disassemble and move after use. For this reason, we propose a steel structure for the heating furnace body. Utility Model Content

[0027] The heat preservation component is arranged on the top of the base 1, and is used to protect the furnace body and prevent the temperature inside from leaking out;

[0028] The sealed component is arranged on the top of the thermal insulation component, and is used to seal the entire steel structure.

[0029] Furthermore, the fixed connecting frame 3 includes a clamping frame 5, a mounting seat 6, a slide groove 7 and a screw rod 8. The mounting seat 6 is cross-shaped as a whole. A slide groove 7 for sliding is opened on the top of the mounting seat 6. Both ends of the inner side of the slide groove 7 are slidably installed with mounting seats 6. The mounting seat 6 is semi-arc-shaped as a whole. The bottoms of the two groups of mounting seats 6 are threadedly connected to the screw rod 8. Through the setting of the fixed connecting frame 3, before installing the furnace body, the fixed connecting frame 3 is first placed on the bottom of the furnace body, and then the screw rod 8 is rotated to drive the two groups of clamping frames 5 to shrink and slide inward synchronously inside the slide groove 7 until the inner wall surfaces of the clamping frames 5 on both sides are fitted and fixed to the bottom of the furnace body. When installing the furnace body, the mounting seat 6 is snap-fitted and installed inside the plug-in slot 2 opened on the top of the base 1, thereby assisting the installation of the furnace body and making the installation more convenient and quick.

[0030] Furthermore, the insulation component includes a carrying ring 9, an insulation ring 10, a connecting ring groove 11 and a connecting ring block 12. The carrying ring 9 is fixedly installed on the top of the base 1. The top of the carrying ring 9 is provided with a connecting ring groove 11. The top of the carrying ring 9 is plugged with an insulation ring 10. The tops of the insulation rings 10 are all provided with connecting ring grooves 11. The bottoms of the insulation rings 10 are all fixedly installed with connecting ring blocks 12 that fit with the connecting ring grooves 11. Several insulation rings 10 are plugged into each other and stacked and installed together.

[0031] Furthermore, the limit rod 4 is threadedly connected with the supporting ring 9, and the positions of the limit rods 4 corresponding to the several insulation rings 10 are provided with corresponding installation grooves 13. Through the setting of the insulation component, after the furnace body is installed, the limit rods 4 of appropriate length are selected according to the height of the furnace body, and then they are threadedly installed on the top of the supporting ring 9 in sequence. After the installation is completed, the installation grooves 13 opened on the several insulation rings 10 are aligned with the several limit rods 4 in sequence, and then they are inserted in sequence, and the connecting ring blocks 12 fixedly installed on the bottom of the insulation rings 10 cooperate with the connecting ring grooves 11 opened on the top thereof, so that the several insulation rings 10 are stacked and plugged together until the stacked height of the several insulation rings 10 is basically the same as the furnace body, and the installation is completed. During installation, it is suitable for installation and use of furnace bodies of various heights, which is more practical.

[0032] Furthermore, the insulation ring 10 has a three-layer structure as a whole. The inner layer of the insulation ring 10 is an aluminum silicate plate that is resistant to high temperatures and has heat insulation effects. The middle layer of the insulation ring 10 is a high-strength carbon steel plate. The outer layer of the insulation ring 10 is a chromium alloy wear-resistant steel plate. Since the insulation ring 10 has a three-layer structure as a whole, when a heating furnace is used, the aluminum silicate plate of the inner layer enables the entire structure to operate stably in an extremely high temperature environment, and its excellent thermal stability ensures that it will not deform or be damaged at high temperatures. At the same time, its excellent thermal insulation performance effectively prevents heat from being transferred to the outside, thereby improving the insulation effect of the overall structure. The high-strength carbon steel plate of the middle layer effectively enhances the strength and stability of the overall structure, and the chromium alloy wear-resistant steel plate of the outer layer greatly improves the wear resistance and corrosion resistance of the plate, thereby extending the service life of the overall structure and making it more practical.

Through the setting of the sealing component, after the installation of several insulation rings 10, the sealed cover plate 14 can be inserted into the top insulation ring 10 through several connection grooves 15 opened on the sealed cover plate 14, and then the sealed cover plate 14 can be fixed by anti-loosening and anti-retraction nuts to complete the overall installation. When in use, the internal temperature can be observed through the temperature measuring window 16 opened on the top of the sealed cover plate 14, which is more convenient for the use of the heating furnace.
