Description

Technical Field

[0001] This utility model relates to the field of crucible protection technology, and in particular to a detachable protective liner for magnesium alloy smelting crucibles. Background Technology

[0002] Magnesium alloy crucibles are high-temperature resistant containers made of bimetallic composite materials, primarily used in the smelting, die-casting, and casting processes of magnesium and magnesium alloys. The material is characterized by high high-temperature strength, strong resistance to protective gas corrosion, and high oxidation resistance, resulting in a long service life.

[0003] Currently, existing magnesium alloy crucibles require support brackets for fixing during casting. However, most of the existing brackets used to support the crucibles are integrally welded tubular components, which can only support and fix the crucibles, but cannot adjust the receiving angle of the crucibles according to the material pouring needs. This has certain limitations in use. In addition, the crucibles will transmit high temperatures during casting operations, which can easily lead to burns for workers during subsequent operations.

[0004] Therefore, this application proposes a detachable protective bushing for magnesium alloy melting crucibles. Utility Model Content

[0005] The purpose of this invention is to provide a detachable protective bushing for magnesium alloy melting crucibles to solve the problems mentioned in the background art.

[0006] A detachable protective bushing for a magnesium alloy melting crucible includes a base and an outer shell. The crucible body is disposed inside the outer shell, and an angle adjustment mechanism is provided between the outer shell and the base. The angle adjustment mechanism includes two symmetrical support plates fixedly mounted on the upper surface of the base. Each support plate has a through-hole for mounting. Connecting rods are fixedly connected to both sides of the outer shell through these mounting openings. The outer shell is rotatably connected to the two support plates via the connecting rods. A fixing groove is formed in the inner top wall of the mounting opening. A rotating opening penetrating the fixing groove is formed on the upper surface of the support plate. An operating rod is rotatably connected to the inner wall of the rotating opening. The lower end of the operating rod extends into the fixing groove and is fixedly connected to a screw. A threaded cylinder is threaded onto the surface of the screw. A limiting tooth is provided at the lower end of the threaded cylinder. Several grooves arranged in a circumferential array and adapted to the limiting tooth are formed on the surface of the connecting rod.

[0007] In a preferred embodiment, guide sliders are provided on both the front and back sides of the threaded cylinder, and guide grooves for the guide sliders to slide are provided on both the inner front wall and inner rear wall of the fixing groove.

[0008] By setting a guide slider, the threaded cylinder can move up and down in a directional manner through the rotation of the screw and the limiting teeth under the guidance of the guide slider.

[0009] In a preferred embodiment, the inner wall of the outer shell is fitted with an insulation layer, which is made of expanded perlite material.

[0010] The high temperature after the crucible body is filled with slurry can be blocked by the insulation layer.

[0011] In a preferred embodiment, the upper surfaces of both the crucible body and the outer shell are provided with a plurality of screw holes, and the inner walls of the screw holes are threaded with mounting bolts. The crucible body is fixedly installed to the outer shell by means of the mounting bolts.

[0012] In a preferred embodiment, the transfer mechanism includes a mounting groove formed on the lower surface of the base, a threaded rod rotatably connected to the inner top wall of the mounting groove, a transmission opening extending through the mounting groove on the right side surface of the base, a crank handle rotatably connected to the inner wall of the transmission opening, bevel gears fixedly connected to the left end of the crank handle and the surface of the threaded rod, a base plate threadedly connected to the surface of the threaded rod, and four universal wheels arranged in a rectangular array mounted on the lower surface of the base plate.

[0013] In a preferred embodiment, the two bevel gears mesh with each other, and the crank handle is connected to the threaded rod via the bevel gears.

[0014] In a preferred embodiment, the front and back of the base plate are provided with limit sliders, and the inner front wall and inner rear wall of the mounting groove are provided with limit grooves for the limit sliders to slide.

[0015] By setting a limit slider, the base plate can move up and down in a directional manner through the rotation of the threaded rod, driven by the limit slider.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, rotating the operating lever drives the screw to rotate. Under the rotation of the screw, the threaded cylinder moves the limiting protrusion upward into the fixed groove, causing the limiting protrusion to separate from the groove on the surface of the connecting rod. Without the limitation of the limiting protrusion, the outer shell is pushed to tilt the crucible body. Then, rotating the screw causes the threaded cylinder to drive the limiting protrusion into the groove on the surface of the connecting rod, fixing the angle of the tilted crucible body. The receiving angle of the crucible body can then be adjusted according to the material pouring requirements.

[0017] Secondly, when it is necessary to move the crucible body, turn the crank handle to drive the threaded rod to rotate through the bevel gear. Under the guidance of the limit slider, the base plate can be driven by the rotation of the threaded rod to move the caster downwards until the caster moves down to contact the ground and lifts the base. At this time, the crucible body can be moved by the caster without the need for manual or equipment lifting, which provides convenience for its transfer work. Attached Figure Description

[0024] The inner wall of the outer shell 2 is embedded with an insulation layer 11, which is made of expanded perlite. The insulation layer 11 can block the high temperature after the crucible body 3 is injected with slurry.

[0025] The upper surfaces of both the crucible body 3 and the outer shell 2 are provided with several screw holes, and the inner walls of the screw holes are threaded with mounting bolts 12. The crucible body 3 is fixedly installed to the outer shell 2 by the mounting bolts 12.

[0026] Reference Figure 2 and Figure 5 In a preferred embodiment, the transfer mechanism includes a mounting groove formed on the lower surface of the base 1. A threaded rod 13 is rotatably connected to the inner top wall of the mounting groove. A transmission opening extending through the mounting groove is formed on the right side surface of the base 1.

When it is necessary to adjust the tilting angle of the crucible body 3, the operating rod is rotated to drive the screw 6 to rotate. Under the rotation of the screw 6, the threaded cylinder 7 drives the limiting tooth 8 to move upward into the fixing groove, so that the limiting tooth 8 separates from the groove 9 on the surface of the connecting rod 5. Without the restriction of the limiting tooth 8, the outer shell 2 is pushed to tilt the crucible body 3. Then, the screw 6 is rotated to tilt the threaded cylinder 7. The cylinder 7 drives the limiting tooth 8 to insert into the groove 9 on the surface of the connecting rod 5, fixing the angle of the crucible body 3 after tilting. The receiving angle of the crucible body 3 can be adjusted according to the material pouring needs. When it is necessary to move the crucible body 3, turn the handle 14 to drive the threaded rod 13 to rotate through the bevel gear 15. Under the guidance of the limiting slider 18, the base plate 16 can drive the universal wheel 17 to move down through the rotation of the threaded rod 13 until the universal wheel 17 moves down to contact the ground and lifts the base 1. At this time, the crucible body 3 can be moved by the universal wheel 17 without the need for manual or equipment lifting.
