Description

Technical Field

[0001] The utility model relates to the technical field of experimental devices, in particular to a copper smelting casting stopper rod screening experimental device. Background Art

[0002] Stopper rods are indispensable as flow control devices in the copper smelting and casting process. The selection and life of stopper rod materials have a great impact on the production process. At present, commonly used stopper rods include graphite stopper rods and stainless steel stopper rods, which have the problems of short life and unstable performance. The development process of new stopper rod materials requires rapid screening experiments of different stopper rod materials, so a copper smelting and casting stopper rod screening experimental device is needed. The existing experimental device uses a high-temperature box furnace and a crucible. Copper raw materials are added to the crucible, and the temperature is increased to turn the copper raw materials into copper melt. Then, multiple stopper rod samples are placed in the crucible. After keeping warm for a specific time, the stopper rod samples are taken out to observe the corrosion status of different sample stopper rod materials, so as to screen stopper rod materials with good performance. In the experiment, the crucible is filled with copper melt, and the stopper rod samples are placed in the crucible. The stopper rod samples need to be taken out later. Taking and placing stopper rod samples in the crucible can easily cause the crucible to tip over, which is dangerous. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a copper smelting casting stopper rod screening experimental device. The crucible can be taken out or put into the cavity of the box-type furnace body by pulling, so the stability of the crucible can be maintained, and the crucible can be avoided from being knocked over when the stopper rod sample is taken out and placed. A copper liquid splash-proof mechanism is provided, and any copper liquid splashed during operation will be collected and will not spill into the cavity. The device has high safety and can effectively solve the problems in the background technology.

[0004] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a copper smelting casting stopper rod screening experimental device, comprising:

[0005] The box-type furnace body has a cavity on the top of the front side, and a crucible push-pull and take-and-place mechanism is installed at the bottom of the cavity;

[0006] The crucible support and limiting mechanism comprises bolts, a fixed plate, a baffle rod, a top ring and a bottom support assembly. The top of the mounting plate in the crucible push-pull pick-up and placement mechanism is fixedly connected to the fixed plate by bolts, the side ring array of the fixed plate is connected to the bottom of four baffle rods, a bottom support assembly is installed between the four baffle rods, the top of the four baffle rods is fixedly connected to the bottom of the top ring, a crucible is arranged on the inner side of the top ring, and the bottom of the crucible is placed on the bottom support assembly;

[0007] The copper liquid splash prevention mechanism is installed on the outer peripheral side of the top ring.

[0008] The cavity on the box-type furnace body is used to place the crucible, and the copper raw material in the crucible is heated to form molten copper. Then, multiple stopper rod samples of different materials are placed in the crucible, and then the temperature is kept constant for a certain period of time. Multiple stopper rod samples are taken out to observe their respective corrosion status, and stopper rod samples with good performance can be screened out. The crucible push-pull pick-up and put-down mechanism can facilitate the sliding of the fixed plate back and forth, so that the crucible can be moved in and out of the cavity. This method can ensure that the crucible can move back and forth smoothly. The bolts fix the fixed plate so that the fixed plate can be disassembled and replaced. The fixed plate, the baffle rod, and the top ring form a conical fence to protect the crucible. The top ring limits the outer peripheral side of the crucible to prevent the crucible from tipping over and the molten copper in the crucible from overflowing or splashing out. The bottom support assembly lifts the bottom of the crucible to facilitate heating the bottom of the crucible and prevent the bottom of the crucible from being blocked by the fixed plate and heating up slowly. The copper liquid splash-proof mechanism can receive the overflowed or splashed copper liquid to prevent the copper liquid from falling into the cavity or on the ground, which has high safety.

The top of each dovetail slider is respectively fixedly connected with two support blocks. The tops of the four support blocks are respectively fixedly connected with the four corners of the mounting plate. The rear end of the dovetail slider is connected with an anti-slip assembly. The dovetail slider slides forward and backward along the dovetail slide, so that the support block and the mounting plate can slide forward and backward in the cavity. When the material in the crucible needs to be operated, the mounting plate is moved forward and out of the cavity. The anti-slip assembly can prevent the dovetail slide and the dovetail slider from detaching, which may cause the mounting plate, the crucible support limiting mechanism and the crucible to fall and cause danger.

[0012] Furthermore, the anti-slip assembly includes a limited slide groove, a fixing screw and a limited slider. A limited slide groove is provided at the bottom of the cavity and communicates with the upper middle part of the dovetail slide groove. The limited slider is slidably connected in the limited slide groove, and the limited slider is fixedly connected to the corresponding rear end of the dovetail slide bar by a fixing screw. The front end of the limited slide groove does not extend to the front side of the cavity, so that the limited slider cannot slip off from the front end of the limited slide groove, and the dovetail slide groove and the dovetail slide bar will not be completely separated. The limited slider and the rear end of the dovetail slide bar are fixed by fixing screws to facilitate the assembly of the anti-slip assembly.

[0013] Furthermore, the crucible push-pull placement mechanism further comprises a handle, and the front end of the mounting plate is fixedly connected with the handle, so that the handle facilitates the push-pull operation of the mounting plate.

[0014] Furthermore, the copper liquid splash prevention mechanism includes a slot, a mounting block and an annular groove body, two slots are symmetrically provided on the top of the outer peripheral side of the top ring, two mounting blocks are fixedly connected to the inner side of the annular groove body, and the two mounting blocks are respectively engaged with the two slots, the outer edge height of the annular groove body is higher than the inner edge height, and the inner edge top surface of the annular groove body is flush with the top surface of the top ring, so that the copper melt overflowing from the crucible can be better collected, and the annular groove body is detachably installed on the outer peripheral side of the top ring by means of the slot and the mounting block, and can be replaced after the annular groove body has been used for a long time and there is a lot of copper inside.

[0015] Furthermore, the copper liquid splash prevention mechanism also includes a handle, and the top two sides of the annular trough body are respectively fixedly connected with a handle. When the annular trough body is replaced, the annular trough body can be lifted with the help of the handle to disengage the card slot and the installation card block.
