Description

Technical Field

[0001] The present application relates to the technical field of steel casting auxiliary equipment, and in particular to an argon gas box. Background Art

[0002] Argon is essential in the pouring process of steel ingots and electrode ingots. First, before pouring, in order to prevent oxidation of molten steel, a large amount of argon needs to be quickly introduced into the pouring cavity to replace the air in the cavity. Then, during the pouring process, argon is also needed at the molten steel mouth to form a strong airflow ring curtain, so that the molten steel is in an airless environment to prevent large amounts of molten steel from inhaling air and secondary oxidation, ensuring the purity of the molten steel and improving the quality of the steel ingots. At present, the argon used for pouring steel ingots and electrode ingots is supplied by the same argon channel, and an argon box will be set on the channel to divert the argon so that the argon can be transmitted to multiple processing stations.

[0003] The argon box includes a box body with a switch door on one side, an argon diversion tank installed inside the box body, and a plurality of branch pipes installed on and connected to the argon diversion tank. The branch pipes will extend to other workstations using argon.

[0004] In the related art, the argon gas diversion tank is installed and limited inside the box through a U-shaped clamp rod. Specifically, a support is welded on the inner wall of the box away from the closing door, and a through hole is opened on the support to penetrate the support. The opening of the U-shaped clamp rod faces the support and the two rods of the U-shaped clamp rod pass through the through hole and are connected to the support through nuts, thereby fixing the argon gas diversion tank on the support. In addition, in order to reduce production costs, the overall size of the box is small, so the internal space of the box is small, and when fixing the argon gas diversion tank, the U-shaped clamp rod must be inserted into the through hole of the support, and then the staff holds the nut with their fingers and tightens it on the U-shaped clamp rod on the side of the support away from the argon gas diversion tank.

[0005] With regard to the above-mentioned related technologies, since the space inside the box is small, the gap between the support and the inner wall of the box away from the closed door side is also small; at this time, it is difficult for the staff to exert force when putting their hands into the gap to tighten the nut on the U-shaped clamp rod, and it is also difficult to use a wrench to tighten the nut due to the narrow space, which makes it inconvenient to fix the argon gas diversion tank. Utility Model Content

[0006] In order to improve the convenience when fixing the argon gas diversion tank, the present application provides an argon gas box.

[0007] The present application provides an argon box, which adopts the following technical solution:

[0008] An argon box comprises a box body and an argon gas diverter tank, a accommodating chamber is opened on one side of the box body, a mounting seat is fixedly installed on the bottom of the accommodating chamber, a semicircular ring is provided on the mounting seat to limit the argon gas diverter tank on the mounting seat, a threaded rod is provided on one side of the mounting seat close to the cavity opening of the accommodating chamber, one side of the semicircular ring is hinged to the mounting seat, and the other side allows the threaded rod to pass through and then be fixed to the mounting seat by a nut.

[0009] In order to facilitate the installation of the semicircular ring on the mounting seat, a hinged ear hinged to the mounting seat is fixedly provided on one side of the semicircular ring along the extension direction of the arc, and a fixed ear connected to the threaded rod is fixedly provided on the side of the semicircular ring away from the hinged ear, and a through hole is opened on the fixed ear for the threaded rod to pass through.

[0010] In order to facilitate opening of the semicircular ring after loosening the nut, the end of the fixing ear away from the semicircular ring protrudes from the mounting seat in a cantilevered state.

[0011] In order to facilitate pre-fixing the argon gas diversion tank on the mounting seat, a semicircular groove for the argon gas diversion tank to be inserted is provided on one side of the mounting seat close to the semicircular ring.

[0012] In order to prevent the argon gas diversion tank from being easily worn or bumped due to resonance caused by vibration of other equipment after installation, a gasket groove is provided at the bottom of the semicircular groove, and a rubber gasket is installed in the gasket groove. The side of the rubber gasket facing away from the bottom of the gasket groove abuts against the argon gas diversion tank.

[0013] A rubber half ring piece is arranged on one side of the semicircular ring close to the mounting seat, and the rubber half ring piece abuts against the argon gas diversion tank.

[0014] In order to prevent the argon gas diversion tank from moving along its own length direction after installation, a friction pattern for increasing the friction between the rubber semi-ring piece and the argon gas diversion tank is provided on the side close to the argon gas diversion tank.

[0015] In order to enable the argon gas diversion tank to be connected to the argon gas pipelines on other workstations, the argon gas diversion tank is provided with a main gas inlet pipe head and multiple gas outlet pipe heads, and the multiple gas outlet pipe heads are arranged at intervals on the argon gas diversion tank.

[0016] In order to adjust the gas flow rate of argon gas entering the argon gas diversion tank, a main manual valve is connected to the main air inlet pipe head.

[0017] In summary, the present application includes at least one of the following beneficial technical effects:

[0018] When fixing the argon gas diversion tank, the argon gas diversion tank is first placed in the semicircular groove of the mounting seat for pre-installation and fixing, and then the semicircular ring is rotated to make the semicircular ring buckle on the mounting seat, and the threaded rod is passed through the through hole, and finally the bolt is directly screwed on the threaded rod to fix the semicircular ring. Compared with the prior art in which the nut is held by hand and inserted into the gap between the fixing seat and the inner wall of the box to screw the nut, the above technology has a larger operating space, and only the semicircular ring needs to be rotated, which makes the operation more convenient.

[0019] When the resonance caused by the vibration of the equipment around the argon box is transmitted to the argon diverter tank, the setting of the rubber gasket and the rubber half ring plays a role in protecting the argon diverter tank. In addition, if the nut that cooperates with the threaded rod becomes loose, the rubber gasket and the rubber half ring are both made of elastic materials, which can offset the gap caused by the loosening of the nut, further improving the stability of the argon diverter tank after installation.

[0024] The following is combined with Figure 1-3 This application is described in further detail.

[0025] The present application embodiment discloses an argon gas box. Figure 1 and Figure 2The argon box includes a box body 1 and an argon gas diverter 2. A receiving chamber 11 is provided on one side of the box body 1. A mounting seat 12 is fixedly installed on the bottom of the receiving chamber 11. A semicircular ring 13 is provided on the mounting seat 12 to limit the argon gas diverter 2 on the mounting seat 12. A threaded rod 14 is provided on one side of the mounting seat 12 near the opening of the receiving chamber 11. One side of the semicircular ring 13 is hinged to the mounting seat 12, and the other side allows the threaded rod 14 to pass through and be fixed to the mounting seat 12 through a nut. In the above scheme, the threaded rod 14 faces the opening of the receiving chamber 11, so the space for installing the nut is large enough and convenient, which makes it more convenient to fix the argon gas diverter 2.

[0026] Reference Figure 1 and Figure 2 A switch door 15 is hinged at the opening of the accommodating chamber 11. When the switch door 15 is closed, the opening of the accommodating chamber 11 can be completely covered. The argon gas diversion tank 2 is a cylindrical tank. Due to the characteristics of argon gas, the material and processing requirements of the argon gas diversion tank 2 are inconsistent with those of the box body 1, so that the argon gas diversion tank 2 needs to be installed separately in the box body 1 during the assembly process.

[0027] Reference Figure 1 and Figure 2 A main air inlet pipe head 21 is integrally formed at one end of the argon gas diversion tank 2, and the main air inlet pipe head 21 is connected to the inside of the argon gas diversion tank 2. A main manual valve 22 is installed on the main air inlet pipe head 21, and the flow rate of argon gas entering the argon gas diversion tank 2 is controlled by the main manual valve 22. In addition, the main manual valve 22 can also control whether argon gas can enter the argon gas diversion tank 2.

[0028] An argon main pipe 23 that can be connected to the argon main pipeline is installed at one end of the main manual valve 22 away from the argon diversion tank 2. The argon main pipe 23 passes through the box body 1 and is exposed to the outside. A flange 231 is integrally formed on the end of the argon main pipe 23 exposed to the outside of the box body 1, which facilitates docking with the argon main pipeline.

[0029] Reference Figure 1 and Figure 2 A plurality of outlet gas pipe heads 24 are integrally formed on the outer wall of the argon gas diversion tank 2, and the plurality of outlet gas pipe heads 24 are arranged at intervals along the axial direction of the argon gas diversion tank 2. Each outlet gas pipe head 24 can disperse the argon gas in the argon gas diversion tank 2 to the corresponding workstation. A branch manual valve 25 is installed on each outlet gas pipe head 24, and a pipe hole 16 is provided on the side wall of the accommodating chamber 11 to facilitate the connection between the pipe on the argon gas branch and the branch manual valve 25. The number of pipe holes 16 is consistent with the number of outlet gas pipe heads 24. In this embodiment, two outlet gas pipe heads 24 are preferably provided.

[0030] Two mounting seats 12 are provided, and the two mounting seats 12 are arranged at intervals along the axial direction of the argon gas splitter. Since two mounting seats 12 are provided, two semicircular rings 13 are also provided, and the two semicircular rings 13 correspond to the two mounting seats 12 one by one. The two mounting seats 12 and the two semicircular rings 13 have the same structure, so the following takes the cooperation of one mounting seat 12 and one semicircular ring 13 as an example for explanation.

[0031] Reference Figure 2 and Figure 3 A semicircular groove 121 is provided on one side of the mounting seat 12 close to the semicircular ring 13. The semicircular groove 121 cooperates with the semicircular ring 13 to form a circular hole for the argon gas diversion tank 2 to be placed. A semicircular arc-shaped gasket groove 122 is provided at the bottom of the semicircular groove 121. The extension direction of the gasket groove 122 is consistent with the extension direction of the semicircular groove 121, and the gasket groove 122 does not penetrate the mounting seat 12 along the axial direction of the semicircular groove 121. A rubber gasket 123 is installed in the gasket groove 122. The side of the rubber gasket 123 close to the argon gas diversion tank 2 protrudes from the gasket groove 122 and presses against the argon gas diversion tank 2. As a result, the argon gas diversion tank 2 is not easily in direct contact with the mounting seat 12 and causes wear after being vibrated.

[0032] Reference Figure 2 and Figure 3 The semicircular ring 13 has hinged ears 17 and fixed ears 18 formed in one piece at both ends along the direction of its arc extension. The hinged ears 17 are located on one side of the semicircular groove 121 and fit on the top of the mounting seat 12. A hinge 19 is installed on the side wall of the hinged ears 17, and the other piece of the hinge 19 is fixedly installed on the side wall of the mounting seat 12, so that the semicircular ring 13 is connected to the mounting seat 12. The threaded rod 14 is welded to the top of the mounting seat 12, and the threaded rod 14 is located on the side of the semicircular groove 121 away from the hinge 19. The fixed ears 18 are provided with waist-shaped through holes 181. After the semicircular ring 13 is buckled, the threaded rod 14 will pass through the through holes 181, and then the nut is tightened on the threaded rod 14, so that the semicircular ring 13 is fixed on the mounting seat 12.

[0033] One end of the fixing lug 18 away from the semicircular ring 13 protrudes from the mounting seat 12 in a cantilevered state, so that when the semicircular ring 13 is opened, the fixing lug 18 can be pressed by hand.

[0034] Reference Figure 2 and Figure 3The semicircular ring 13 is provided with an arc groove on one side close to the mounting seat 12, and a rubber semi-ring piece 131 is placed in the arc groove. The rubber semi-ring piece 131 protrudes from the arc groove and is pressed against the argon gas diversion tank 2. Then the rubber semi-ring piece and the rubber gasket 123 are wrapped around the argon gas diversion tank 2. In addition, the rubber semi-ring piece 131 is provided with a friction pattern on one side close to the argon gas diversion tank 2 to increase the friction between the rubber semi-ring piece 131 and the argon gas diversion tank 2.

[0035] The implementation principle of an argon box in an embodiment of the present application is as follows: when fixing the argon diverter tank 2, the argon diverter tank 2 is first placed in the semicircular groove 121 of the mounting seat 12 for pre-installation and fixing, and then the semicircular ring 13 is rotated to make the semicircular ring 13 buckle on the mounting seat 12, and at the same time, the threaded rod 14 is passed through the through hole 181, and finally the semicircular ring 13 is directly screwed on the threaded rod 14 to fix it. When the resonance generated by the vibration of the equipment around the argon box is transmitted to the argon diverter tank 2, the setting of the rubber gasket 123 and the rubber semi-ring piece 131 plays a role in protecting the argon diverter tank 2. In addition, if the nut matched with the threaded rod 14 is loosened, since the rubber gasket 123 and the rubber semi-ring piece are both made of elastic materials, the gap caused by the loosening of the nut can be offset, further improving the stability of the argon diverter tank 2 after installation.

[0036] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
