[0028] The following description, in conjunction with the accompanying drawings, describes a carbon steel anti-oxidation hood furnace according to an embodiment of the present invention.

[0029] Reference Figure 1 The present invention aims to provide an embodiment of an anti-oxidation furnace for carbon steel parts.

[0030] This utility model provides an embodiment of a carbon steel anti-oxidation hood furnace, referring to... Figure 1 It includes a base 100, the top surface of the base 100 has a groove 110 and a plurality of protrusions 120 disposed in the groove 110, refractory sand is laid between the groove 110 and the protrusions 120, and the top surface of the plurality of protrusions 120 is used to place carbon steel parts.

[0031] Understandably, by setting up a base 100 with a groove 110 and a boss 120, refractory sand is laid in the groove 110, and the high-temperature carbon steel part is placed on the boss 120. The cover 150 is then used to cover the carbon steel part, and the opening edge of the cover 150 is inserted with refractory sand, so that the inside of the cover 150 is sealed, isolating the carbon steel part from the outside air and greatly reducing the problem of the carbon steel part oxidizing and forming a layer of oxide scale.

[0032] An embodiment of the present invention provides a carbon steel anti-oxidation furnace, which further includes a winding and unwinding mechanism and a cover-fastening mechanism. The winding and unwinding mechanism includes multiple unwinding reels 130 and a motor 140 that drives the multiple unwinding reels 130 to rotate. The multiple unwinding reels 130 are coaxially connected. The cover-fastening mechanism includes multiple cover-fastening assemblies, the number of which matches the number of bosses 120. Each cover-fastening assembly includes a cover body 150, a hanging rope 160, and a fixed pulley system. The cover body 150 is used to cover the carbon steel parts on the bosses 120. Refractory sand can be inserted into the opening edge of the cover body 150. One end of the hanging rope 160 is tied to the top of the cover body 150, and the other end of the hanging rope 160 is tied to the unwinding reel after passing around the fixed pulley system.

[0033] It is understandable that by setting up multiple unwinding reels 130 and motors 140, and coaxially connecting the multiple unwinding reels 130, the motors 140 can simultaneously drive the multiple unwinding reels 130, as shown in the reference. Figure 1 , Figure 2 and Figure 3 Furthermore, by setting up multiple cover-fastening components, each equipped with a release reel 130, the cover-fastening component includes a cover body 150, a lifting rope 160, and a fixed pulley system. The lifting rope 160 is wound around the release reel 130, and after passing through the fixed pulley system, it connects to the top of the cover body 150. The motor 140 drives the release reel 130 to rotate, and the release reel 130 releases the lifting rope 160. The cover body 150 moves downward under its own weight. The lifting rope 160 is kept taut through the fixed pulley system, reducing the problem of positional deviation when the cover body 150 descends, and ensuring that the cover body 150 accurately covers the carbon steel parts. At the same time, multiple release reels 130 release the lifting rope 160 simultaneously, so that multiple covers 150 descend or rise simultaneously, replacing manual covering of the carbon steel parts with the cover 150, which is more time-saving and labor-saving, and helps to improve the operational efficiency of the anti-oxidation treatment process.

[0034] Because carbon steel parts have high temperatures, in order to prevent the boss 120 from being damaged by high temperatures, in some embodiments of this utility model, the boss 120 is made of refractory bricks. Refractory bricks can withstand high temperatures, which improves the service life of the boss 120.

[0035] In some embodiments of this utility model, reference is made to Figure 3 Each of the multiple unwinding reels 130 has a rotating shaft 170, and the rotating shafts 170 between the multiple unwinding reels 130 are connected by a coupling 180. Therefore, by using a coupling 180 to connect and fix the rotating shafts 170 of each unwinding reel 130, it is not necessary to use a rotating shaft 170 that is too long, which facilitates the manufacturing and installation of the rotating shaft 170.

[0036] In some embodiments of this utility model, the fixed pulley group includes a first fixed pulley 190 and a second fixed pulley 200. The first fixed pulley 190 and the second fixed pulley 200 are arranged on the same horizontal plane. The first fixed pulley 190 is located above the cover 150, and the second fixed pulley 200 is located below the unwinding reel 130.

[0037] It is understandable that by setting the first fixed pulley 190 and the second fixed pulley 200, the suspension rope 160 passes around the first fixed pulley 190 and the second fixed pulley 200, making the movement of the suspension rope 160 more stable, less prone to loosening, and less prone to deviation.

[0038] In some embodiments of this utility model, a guide slope 280 is provided at the bottom of the cover 150, and the guide slope 280 extends outward from the cover 150.

[0039] Therefore, during the descent of the cover 150, the guide slope 280 can guide the cover 150 to cover the carbon steel parts, so that the cover 150 accurately covers the carbon steel parts, reducing the problem of the cover 150 falling on the boss 120.

[0040] In some embodiments of this utility model, the cover mechanism includes a top cover 210, which is located above the base 100, and the cover assembly is installed inside the top cover 210.

[0041] Therefore, the main functions of the top cover 210 are: firstly, to install the cover assembly on the top cover 210; and secondly, to block the smoke rising inside the cover 150 after the cover 150 is raised.

[0042] In order to collect the above-mentioned flue gas, in some embodiments of this utility model, the top of the top cover 210 has an exhaust pipe 220 and an exhaust fan 230 disposed on the exhaust pipe 220. The exhaust fan 230 and the exhaust pipe 220 work together to draw the flue gas from the top cover 210 and extract the flue gas to the outside for treatment, thereby greatly reducing the flue gas in the workshop and ensuring a comfortable working environment for the staff.

[0043] In some embodiments of this utility model, a guide rod 240 is provided on the top of the cover 150, and a guide sleeve 250 is provided on the top cover 210. The guide rod 240 and the guide sleeve 250 are slidably connected up and down.

[0044] Therefore, when the cover 150 moves up and down, the guide rod 240 can slide up and down inside the guide sleeve 250, making the movement of the cover 150 more stable and ensuring that the cover 150 accurately covers the carbon steel parts.

[0045] In some embodiments of this utility model, the bottom of the top cover 210 is provided with a plurality of support feet 260, which are mounted on the base 100.

[0046] By setting support feet 260, a certain space is formed between the top cover 210 and the base 100, making it convenient for workers to place carbon steel onto the boss 120.

[0047] In some embodiments of this utility model, the cover-fastening mechanism includes a proximity switch 270 and a bracket connected to the proximity switch 270. The bracket is installed on the top cover 210. The proximity switch 270 is used to limit the position of the cover 150 when it rises. Therefore, after the cover 150 rises to a certain position, the proximity switch 270 can detect the cover 150 and feed back the relevant electrical signal to the control system, so that the motor 140 stops and the cover 150 is kept at a certain height.

[0048] In the description of this specification, references to terms such as "an embodiment," "some embodiments," "illustrative embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0049] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
