Description

Technical Field

[0001] This application relates to the technical field of equipment for calcium carbide furnace production, and in particular to a steel rod straightening device for calcium carbide furnace production. Background Technology

[0002] A calcium carbide furnace is the core device that uses electric arc and resistance heating to react quicklime with carbonaceous raw materials to produce calcium carbide in a high-temperature environment above 2000°C. A steel rod, a pointed steel bar, is mainly used in the "hole-opening" operation during the tapping process of the calcium carbide furnace. Specifically, by using the steel rod to "deeply penetrate and shallowly tap," the furnace opening is opened or enlarged to control the flow rate and stability of the high-temperature molten calcium carbide, thereby preventing blockage or abnormal flow rate and ensuring smooth flow of molten calcium carbide. Because the temperature of molten calcium carbide is approximately 1700-2100°C, the steel rod is prone to bending during prolonged operation, rendering it unusable. To reuse the steel rod, the bent portion usually needs to be cut off, resulting in waste. Therefore, this application proposes a steel rod straightening device for calcium carbide furnace production.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0017] refer to Figures 1 to 4 This application provides a steel rod straightening device for calcium carbide furnace production, comprising: The support body 100 is a hollow structure with through holes 101 on its opposite side walls for the steel rod 200 to pass through. One end of the steel rod 200 extends into the support body 100 through one of the through holes 101 and exits the support body 100 through the other through hole 101, and abuts against the inner bottom surface of the two through holes 101. This achieves the purpose of placing the steel rod 200 on the support body 100 and supporting the steel rod 200 through the support body 100.

[0018] The hydraulic cylinder 300 has its cylinder barrel positioned at the top of the support body 100, with the bottom end of its telescopic rod located inside the support body 100 and connected to a straightening head 400, which is positioned directly above the steel rod 200. To facilitate installation, maintenance, and replacement of the straightening head 400, it can be detachably connected to the bottom end of the telescopic rod of the hydraulic cylinder 300 using fasteners or similar means. Specifically, the straightening head 400 is compatible with the steel rod 200.

[0019] The hydraulic cylinder 300 is used to drive the correction head 400 to move vertically up and down within the support body 100 by extending and retracting its own telescopic rod. This corrects the bent part of the steel rod 200, preventing the bent part of the steel rod 200 from being cut off, thus avoiding waste of the steel rod 200 and improving its utilization rate.

[0020] The steel rod straightening device for calcium carbide furnace production provided in this application comprises a support body 100 with a hollow structure and through holes 101 on its opposite side walls. During the straightening process of the steel rod 200, one end of the steel rod 200 is inserted into the support body 100 through one of the through holes 101 and exits the support body 100 through the other through hole 101, abutting against the inner bottom surface of the two through holes 101. A straightening head 400 is provided at the bottom end of the telescopic rod of the hydraulic cylinder 300. The extension and retraction of the telescopic rod of the hydraulic cylinder 300 drives the straightening head 400 to move vertically up and down within the support body 100. The straightening head 400 applies pressure to the bent part of the steel rod 200 as it moves vertically up and down within the support body 100, thereby straightening the bent part of the steel rod 200. (During the straightening process, the bent part of the steel rod 200 can be straightened by rotating the steel rod 200 or moving the steel rod 200 along its length.) The straightened steel rod 200 can be reused, avoiding the situation where the bent part of the steel rod 200 is cut off, thereby reducing the waste of the steel rod 200 and improving its utilization rate.

[0021] In some embodiments, reference Figure 3 The support body 100 in this application includes two first upright plates 102, two second upright plates 103, and a top plate 104. Specifically, one first upright plate 102, one second upright plate 103, another first upright plate 102, and another second upright plate 103 are arranged to form a square space 500. A support leg 600 is provided between the bottom surface of each first upright plate 102 and the bottom surface of each second upright plate 103. Each second upright plate 103 is provided with a through hole 101. The top plate 104 is provided on the top surface of the two first upright plates 102.

[0022] In the above embodiment, one of the first upright plates 102, one of the second upright plates 103, another first upright plate 102, and another second upright plate 103 are sequentially welded together. The support leg 600 is also welded to the bottom surface of the first upright plate 102 and the bottom surface of the second upright plate 103. The top plate 104 is welded to the two first upright plates 102. During the process of correcting the bent and deformed part of the steel rod 200, the telescopic rod of the hydraulic cylinder 300 drives the correction head 400 to move vertically up and down within the square space 500 formed by the sequentially enclosed first upright plate 102, one of the second upright plates 103, another first upright plate 102, and another second upright plate 103 to apply pressure to the bent part of the steel rod 200 located directly below the correction head 400, thereby straightening the bent part of the steel rod 200. The square space 500 provides space for the telescopic rod of the hydraulic cylinder 300 to move vertically up and down, ensuring the normal progress of the steel rod 200 correction process.

[0023] In some embodiments, reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In this application, each of the first upright plate 102 and the second upright plate 103 has a reinforcing plate 700 on its opposite side walls perpendicular to each other; wherein the reinforcing plate 700 is right-angled, and the two right-angled sides of each reinforcing plate 700 are connected to the first upright plate 102 and the top plate 104 respectively.

[0024] In the above embodiment, the two right-angled sides of the reinforcing plate 700 are connected to the first upright plate 102 and the top plate 104 by welding, respectively. The setting of the reinforcing plate 700 makes the connection between the first upright plate 102 and the top plate 104 more stable, thereby improving the stability of the support body 100 during the correction process of the steel rod 200.

[0025] In some embodiments, reference Figure 1 and Figure 2 In this application, each of the second upright plates 103 has a positioning groove 1031 in the middle of its top surface, and the positioning groove 1031 is adapted to the steel rod 200.

[0026] In the above embodiments, since the steel rod 200 is a pointed steel rod, and the positioning groove 1031 is adapted to the steel rod 200, that is, the positioning groove 1031 is usually a semi-circular groove. The purpose is to embed the steel rod 200 in the positioning groove 1031 and limit the steel rod 200 through the positioning groove 1031, thereby improving the stability of the steel rod 200 during the calibration process.

[0027] In some embodiments, reference Figure 1 , Figure 2 and Figure 3In this application, the top plate 104 is provided with an installation through hole 1041, and the outer peripheral wall of the cylinder of the hydraulic cylinder 300 is provided with an annular retaining plate 301; wherein, the inner peripheral wall of the annular retaining plate 301 is fixedly connected to the outer peripheral wall of the cylinder of the hydraulic cylinder 300.

[0028] The inner diameter of the annular plate 301 is larger than the diameter of the mounting through hole 1041, and its bottom surface is in contact with the upper surface of the top plate 104.

[0029] In the above embodiment, since the inner diameter of the annular plate 301 is larger than the diameter of the mounting through hole 1041, the bottom surface of the annular plate 301, which is fixedly connected to the hydraulic cylinder 300 when the hydraulic cylinder 300 is installed, can contact the upper surface of the top plate 104, thereby realizing the connection between the hydraulic cylinder 300 and the support body 100, which facilitates the installation and disassembly of the hydraulic cylinder 300.

[0030] In some embodiments, reference Figure 1 and Figure 2 In this application, a limiting plate 800 is provided on the top plate 104, and a limiting groove 801 with a lower opening is provided on the limiting plate 800. The inner top surface of the limiting groove 801 abuts against the top surface of the cylinder of the hydraulic cylinder 300.

[0031] In the above embodiments, after the hydraulic cylinder 300 is installed on the support frame body 100, the top surface of the hydraulic cylinder 300 abuts against the inner top surface of the limiting groove 801. This achieves the connection between the hydraulic cylinder 300 and the support body 100 through the annular clamping plate 301, and further supports the support body 100 through the limiting groove 801, thereby improving the stability of the connection between the hydraulic cylinder 300 and the support body 100.

[0032] In some embodiments, the pressure of the hydraulic cylinder 300 in this application is 0.1 MPa to 0.2 MPa.

[0033] In the above embodiments, excessive pressure of the hydraulic cylinder 300 may worsen the deformation of the bent portion of the steel rod 200, while insufficient pressure may make it difficult to straighten the bent portion of the steel rod 200 or take a long time to straighten it. In other words, the pressure of the hydraulic cylinder 300 needs to be within a suitable range. The pressure of the hydraulic cylinder 300 in this application is between 0.1 MPa and 0.2 MPa, which not only ensures that the straightening head 400 straightens the bent portion of the steel rod 200, but also does not aggravate the deformation of the bent portion of the steel rod 200.

[0034] In some embodiments, the support body 100 in this application is made of steel plate and has a protective layer on its outer surface.

[0035] In the above embodiments, steel plates possess advantages such as high strength, good toughness, corrosion resistance, low cost, and environmental recyclability, resulting in lower manufacturing costs and greater durability for the support body 100. The protective layer can be made of rust-resistant materials such as paint, and can be applied to the outer surface of the support body 100 via spraying or other methods. This reduces the likelihood of corrosion and extends the service life of the support body 100.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
