Description

Technical Field

[0001] This application relates to the field of magnesium smelting technology, and in particular to a clamping device for a reduction tank in magnesium smelting. Background Technology

[0002] In the magnesium smelting process, the reduction vessel is a crucial piece of equipment. However, after prolonged use, the reduction vessel may suffer high-temperature damage, affecting its usability. Furthermore, since reduction vessels are typically made of heat-resistant steel (ZG35Cr24Ni7SiN), they contain a large amount of precious elements (nickel ≥7%, chromium ≥24%, molybdenum, and other rare metals). Directly discarding a high-temperature damaged reduction vessel would result in a significant waste of rare metal resources. However, remelting can recover over 90% of the alloying elements, significantly reducing the production cost of the reduction vessel. Therefore, remelting high-temperature damaged reduction vessels allows for their reuse or replacement. During the remelting process, the clamping and lifting of the reduction vessel are essential steps.

[0003] Due to the shape, weight, and high-temperature environment of the reduction tank, lifting lugs are typically welded to the tank, and then the crane hooks are used to attach the tank to the lugs for clamping and lifting. However, this method is prone to detachment during clamping and lifting operations due to shaking or collisions, which could cause the detached tank to fall onto workers or equipment within the working radius. Therefore, the existing method of clamping and lifting reduction tanks poses significant safety hazards, and the welding of lifting lugs to the tank makes the clamping and lifting process cumbersome, thus affecting the efficiency of clamping and lifting.

The lifting chain has a hook at one end that can be connected to the lifting through hole, and a lifting ring at the other end for connecting to the lifting equipment.

[0006] Optionally, the clamping head includes a first end and a second end disposed opposite to each other; The lifting through hole is opened near the first end and the top of the clamping head, and the clamping groove is opened near the second end on the inner bottom surface of the clamping groove and extends from bottom to top along the height direction of the clamping head.

Detailed Implementation

[0018] 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.

[0019] refer to Figures 1 to 5 This application provides a clamping device for a reducing tank in magnesium smelting, comprising: The clamping head 100 has a lifting through hole 101 and a clamping groove 102. The clamping groove 102 is used to clamp the wall of the magnesium reduction tank 200. In order to facilitate the clamping of the magnesium reduction tank 200 through the clamping groove 102, the clamping groove 102 is formed in the bottom surface of the clamping head 100 and extends to the top of the clamping head 100.

[0020] A clamping assembly 300 is included, one end of which extends through and into the clamping groove 102, abutting against the wall of the magnesium reduction tank 200 within the clamping groove 102 to clamp the magnesium reduction tank 200 within the clamping groove 102. It is detachably connected to the clamping head 100. To improve the versatility of the magnesium reduction tank clamping device, the width of the clamping groove 102 is greater than the thickness of the wall of the magnesium reduction tank 200. The clamping assembly 300 clamps the magnesium reduction tank 200 within the clamping groove 102, improving the stability of the clamping and lifting process. The detachable connection between the clamping assembly 300 and the clamping head 100 makes the clamping process of the magnesium reduction tank 200 within the clamping groove 102 more flexible and easier to operate.

[0021] A lifting chain 400 is provided, with a hook 401 at one end that can connect to a lifting through-hole 101, and a lifting ring 402 at the other end for connecting to lifting equipment. The hook 401 can be welded to one end of the lifting chain 400, and the lifting ring 402 can also be welded to the other end of the lifting chain 400. Furthermore, to ensure the stability of the connection between the hook 401 and the lifting through-hole 101, the hook 401 used in this application is a C-type hook, and the lifting equipment in this application can be a crane.

[0022] The magnesium reduction tank clamping and lifting device provided in this application is configured with a clamping head 100, and a lifting through hole 101 and a clamping groove 102 are provided on the clamping head 100. The clamping groove 102 is aligned with the tank wall of the magnesium reduction tank 200 and the clamping head 100 is moved downward until the top surface of the magnesium reduction tank 200 abuts against the inner top surface of the clamping groove 102. Then, one end of the clamping assembly 300 passes through and extends into the clamping groove 102 and abuts against the tank wall of the magnesium reduction tank 200 in the clamping groove 102 to clamp the magnesium reduction tank 200 in the clamping groove 102. Then, the hook 401 on the lifting chain 400 is connected to the lifting through hole 101, and the lifting equipment is connected to the lifting ring at the other end of the lifting chain 400 to realize the clamping and lifting of the magnesium reduction tank 200. Compared to existing methods that involve welding lifting lugs to the reduction tank and connecting them to hooks on a crane for clamping and lifting, this application eliminates the need for welding lifting lugs to the magnesium reduction tank 200. Furthermore, while the clamping groove 102 on the clamping head 100 clamps the magnesium reduction tank 200, the clamping assembly 300 further tightens the tank within the groove 102, thereby improving the stability of the magnesium reduction tank 200 during clamping or lifting. This results in higher safety during the clamping and lifting process, greater ease of operation, and increased efficiency. Additionally, the clamping groove 102 on the clamping head 100 and the clamping assembly 300 allow this application to handle magnesium reduction tanks 200 with varying wall thicknesses, thus enhancing the versatility of the magnesium reduction tank clamping and lifting device.

[0023] Optionally, to ensure the stability of the magnesium reduction tank 200 during the hoisting process, the two magnesium reduction tank clamping devices of this application can be used during the hoisting process of the magnesium reduction tank 200, with the two magnesium reduction tank clamping devices respectively clamped onto the magnesium reduction tank 200.

[0024] In some embodiments, reference Figures 1 to 5 The clamping head 100 in this application includes a first end 103 and a second end 104 disposed opposite to each other; specifically, a lifting through hole 101 is opened near the first end 103 and the top of the clamping head 100, and a clamping groove 102 is opened near the second end 104 on the inner bottom surface of the clamping groove 102 and extends from bottom to top along the height direction of the clamping head 100.

[0025] In the above embodiment, since the first end 103 and the second end 104 are arranged opposite to each other, and the lifting through hole 101 is opened near the first end 103 and the top of the clamping head 100, and the clamping groove 102 is opened near the second end 104 on the inner bottom surface of the clamping head 100, the lifting through hole 101 and the clamping groove 102 are arranged opposite to each other. In this way, during the process of clamping the magnesium reduction tank 200 through the clamping groove 102 and the clamping assembly 300, the magnesium reduction tank 200 is in an inclined state, so that the force on the lifting chain 400 is the component of the gravity of the magnesium reduction tank 200, making the entire lifting process of the magnesium reduction tank 200 more labor-saving.

[0026] In some embodiments, reference Figures 1 to 5 The clamping head 100 in this application is F-shaped. Compared with the block-shaped clamping head 100, the clamping head 100 in this application is produced in an F-shape, which not only makes it possible to open the lifting through hole 101 and the clamping groove 102 on the clamping head 100, but also reduces the weight of the entire clamping head 100. This reduces the lifting burden on the lifting equipment during the clamping and lifting of the magnesium reduction tank 200, and improves the stability of the clamping and lifting process of the magnesium reduction tank 200.

[0027] In some embodiments, reference Figures 1 to 5 In this application, an anti-slip layer 1021 is provided on the inner surface of the clamping groove 102. The anti-slip layer 1021 can be provided on the inner surface of the clamping groove 102 by means of adhesive or other methods. The provision of the anti-slip layer 1021 increases the friction between the clamping groove 102 and the wall of the magnesium reduction tank 200. This makes it difficult for the magnesium reduction tank 200 to fall out of the clamping groove 102 even under its own weight during the clamping and lifting process, thereby further improving the stability of the clamping and lifting process of the magnesium reduction tank 200.

[0028] In addition, the anti-slip layer 1021 is made of rubber. Due to the many advantages of rubber, such as high coefficient of friction, excellent elasticity and wear resistance, and good aging resistance, the anti-slip layer 1021 made of rubber has a long service life.

[0029] In some embodiments, reference Figures 1 to 5 In this application, the anti-slip layer 1021 has anti-slip protrusions 500 on its side wall away from the clamping groove 102. The anti-slip protrusions 500 can be various patterns, geometric shapes, etc., and their purpose is to further increase the friction between the anti-slip layer 1021 and the inner and outer walls of the magnesium reduction tank 200 in the clamping groove 102, thereby improving the stability of the clamping and lifting process of the magnesium reduction tank 200.

[0030] In some embodiments, reference Figure 5In this application, the second end 104 is provided with a threaded through hole 1041 communicating with the clamping groove 102; specifically, the clamping assembly 300 includes a threaded rod 301 and a nut 302; specifically, the threaded rod 301 is adapted to the threaded through hole 1041, and one end of it passes through the threaded through hole 1041 and abuts against the wall of the magnesium reduction tank 200 in the clamping groove 102, and the nut 302 is sleeved on the rod of the threaded rod 301 located outside the clamping groove 102 to connect the threaded rod 301 and the clamping groove 102 together.

[0031] In the above embodiments, after the clamping groove 102 clamps the wall of the magnesium reduction tank 200, one end of the threaded rod 301 is screwed into the threaded through hole 1041 until one end of the threaded rod 301 abuts against the outer wall of the magnesium reduction tank 200 in the clamping groove 102. The nut 302 is screwed onto the rod of the threaded rod 301 located outside the clamping groove 102, and one side of the nut 302 abuts against the outer wall of the clamping head 100. The above-mentioned threaded rod 301 and nut 302 not only improve the stability of the clamping groove 102 in clamping the magnesium reduction tank 200, but also enable the clamping groove 102 to clamp magnesium reduction tanks 200 with various wall thicknesses, thereby improving the wide applicability of the clamping head 100.

[0032] Furthermore, in order to ensure the clamping force of the threaded rod 301 against the outer wall of the magnesium reduction tank 200 in the clamping groove 102, an abutment plate is provided at one end of the threaded rod 301 located in the clamping groove 102.

[0033] In some embodiments, the depth of the clamping groove 102 in this application is 120cm~200cm, and its width is 50cm~60cm.

[0034] In the above embodiments, to ensure the stability of the clamping groove 102 in clamping magnesium reduction tanks 200 of various specifications (mainly referring to the height and wall thickness) and thicknesses, the clamping groove 102 needs to have a certain depth and width. When the depth of the clamping groove 102 is 120cm~200cm and its width is 50cm~60cm, the clamping groove 102 has wide applicability and can be used for magnesium reduction tanks 200 of various specifications. The magnesium reduction tank 200 used by the applicant has a depth of 160cm and a width of 55cm, thereby achieving effective clamping of the magnesium reduction tank 200 by the clamping groove 102 and the clamping assembly 300.

[0035] In some embodiments, the clamping head 100 in this application is made of cast steel. Cast steel has excellent properties such as high strength, wear resistance, good machinability, fatigue resistance, and vibration resistance. Therefore, the clamping head 100 made of cast steel has a long service life.

[0036] In some embodiments, the lifting chain 400, hook 401, and ring 402 in this application are all made of alloy steel. Because alloy steel possesses excellent properties such as high strength, corrosion resistance, good heat treatment performance, weldability, and forgeability, the lifting chain 400, hook 401, and ring 402 made of alloy steel have significant advantages in the lifting process of the magnesium reduction tank 200, thereby improving the safety and efficiency of the operation of the lifting chain 400, hook 401, and ring 402.

[0037] 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.
