Description

Technical Field

[0001] This utility model relates to the field of smelting furnace technology, specifically to a ash-blocking cover structure for the opening of a titanium ingot smelting furnace. Background Technology

[0002] In titanium processing, titanium ingot melting furnaces are a commonly used device, crucial for melting and heating titanium metal or titanium alloys. The furnace melts titanium into a liquid, facilitating the addition of other elements. During the melting process, ash baffles are used to cover the furnace opening to prevent fumes from escaping.

[0003] Utility model CN219977072U discloses a dust-blocking cover structure for a titanium ingot smelting furnace opening. The structure includes a furnace opening dust-blocking cover body with an ingot inlet / outlet in the center for lifting ingots from the furnace. The upper surface of the cover body has a lifting ring for hoisting, and the lower surface has reinforcing ribs. This utility model, by adding a dust-blocking cover to the upper part of the titanium ingot smelting furnace, prevents dust generated during titanium ingot smelting from falling into the furnace, avoiding damage to components such as the lead screw. The ingot inlet / outlet in the center facilitates the insertion and removal of ingots from the furnace. The structure is simple, easy to manufacture, and effectively prevents dust accumulation without hindering the entry and exit of titanium ingots.

[0004] However, the above technical solution still has certain defects. In the above technical solution, the ingot inlet and outlet are provided in the middle of the ash baffle cover body of the melting furnace, but there is no structure to block the ingot inlet and outlet. As a result, the smoke and ash in the titanium ingot melting furnace will still come out from the ingot inlet and outlet, and the blocking effect on the smoke and ash generated by volatilization during the titanium ingot melting process is poor. Utility Model Content

[0005] The purpose of this invention is to provide a ash-blocking cover structure for the opening of a titanium ingot smelting furnace, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ash-blocking cover structure for the opening of a titanium ingot smelting furnace, comprising:

[0007] A cover plate seat, wherein a mounting groove is provided on the front side of the cover plate seat, and an ingot inlet / outlet is provided in the middle of the rear side of the mounting groove;

[0008] Two ash-blocking gates are symmetrically and slidably arranged on the left and right sides of the mounting groove, and each ash-blocking gate has a handle fixed on its front side.

[0009] Two sets of transmission components are symmetrically arranged on the upper and lower parts of the front side of the cover plate seat. Each transmission component includes a first transmission rod and a second transmission rod. The ends of the first and second transmission rods near the cover plate seat are rotatably connected to the cover plate seat via pins. The ends of the first and second transmission rods near the ash-blocking gates are slidably connected to the corresponding ash-blocking gates. The ends of the first and second transmission rods near the cover plate seat are meshed with each other.

[0010] Preferably, a first arc-shaped rack is fixed to one end of the first transmission rod near the cover plate seat, and a second arc-shaped rack is fixed to one end of the second transmission rod near the cover plate seat. The second arc-shaped rack is meshed with the adjacent first arc-shaped rack, so that when the first transmission rod or the second transmission rod rotates, the meshing action drives the adjacent transmission rod to rotate synchronously.

[0011] Preferably, the front sides of the two ash-blocking gates are symmetrically fixed with slide rails, and the ends of the first and second transmission rods near the ash-blocking gates are rotatably connected to slide blocks via pins. The slide block on the first transmission rod is slidably mounted on the slide rail on the left side of the ash-blocking gate, and the slide block on the second transmission rod is slidably mounted on the slide rail on the right side of the ash-blocking gate.

[0012] Preferably, sliding grooves are provided on both the upper and lower sides of the mounting groove, and sliders are fixed on both the upper and lower sides of the ash-blocking gate. The sliders are slidably nested in the sliding grooves, so that the ash-blocking gate slides stably in the mounting groove.

[0013] Preferably, the cover plate seat is made of high-temperature resistant heat-insulating material to reduce the evaporation of heat inside the titanium ingot smelting furnace.

[0014] Preferably, the ash baffle and handle are both made of high-temperature resistant heat-insulating material to reduce the evaporation of heat in the titanium ingot smelting furnace.

[0015] Preferably, lifting rings are fixed on both the upper and lower parts of the front side of the cover plate seat, on the left and right sides, for lifting the dust cover plate, thereby facilitating the cleaning and replacement of the dust cover plate.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] 1. By installing two ash-blocking gates in front of the ingot inlet and outlet, and providing a transmission component connected to the two ash-blocking gates, when one ash-blocking gate is pulled, the transmission component can drive the other ash-blocking gate to move synchronously, thereby conveniently covering and exposing the ingot inlet and outlet. The two ash-blocking gates cover the ingot inlet and outlet, which can effectively prevent the smoke and ash in the titanium ingot smelting furnace from escaping from the ingot inlet and outlet, and the dust blocking effect is good.

[0018] 2. Lifting rings are fixed on both the upper and lower sides and the left and right sides of the front of the cover plate seat for lifting the ash baffle cover, thereby facilitating the cleaning and replacement of the ash baffle cover. Attached Figure Description

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] This utility model provides, for example Figures 1 to 5 The illustrated ash baffle cover structure for a titanium ingot smelting furnace opening includes:

[0031] The cover plate seat 10 has an installation groove 11 on its front side and an ingot inlet / outlet 12 on the middle of its rear side.

[0032] Two ash-blocking gates 20 are symmetrically and slidably arranged on the left and right sides of the mounting groove 11, and each ash-blocking gate 20 has a handle 21 fixed on its front side.

[0033] Two sets of transmission components 30 are symmetrically arranged on the upper and lower parts of the front side of the cover plate seat 10. Each transmission component 30 includes a first transmission rod 31 and a second transmission rod 32. The ends of the first transmission rod 31 and the second transmission rod 32 near the cover plate seat 10 are rotatably connected to the cover plate seat 10 through pins. The ends of the first transmission rod 31 and the second transmission rod 32 near the ash baffle 20 are slidably connected to the corresponding ash baffle 20. The ends of the first transmission rod 31 and the second transmission rod 32 near the cover plate seat 10 are meshed with each other.

[0034] A first arc-shaped rack 33 is fixed to one end of the first transmission rod 31 near the cover plate seat 10, and a second arc-shaped rack 34 is fixed to one end of the second transmission rod 32 near the cover plate seat 10. The second arc-shaped rack 34 is meshed with the adjacent first arc-shaped rack 33, so that when the first transmission rod 31 or the second transmission rod 32 rotates, the meshing action drives the adjacent transmission rod to rotate synchronously.

[0035] Two ash-blocking gate plates 20 are symmetrically fixed with slide rails 22 on their front sides. The first transmission rod 31 and the second transmission rod 32 are rotatably connected to slide seats 35 at their ends near the ash-blocking gate plates 20 via pins. The slide seats 35 located on the first transmission rod 31 are slidably mounted on the slide rails 22 on the ash-blocking gate plate 20 located on the left side, and the slide seats 35 located on the second transmission rod 32 are slidably mounted on the slide rails 22 on the ash-blocking gate plate 20 located on the right side.

[0036] The mounting groove 11 has sliding grooves 13 on both the upper and lower sides, and the ash-blocking gate 20 has sliders 23 fixed on both the upper and lower sides. The sliders 23 are slidably nested in the sliding grooves 13, so that the ash-blocking gate 20 slides stably in the mounting groove 11.

[0037] The cover plate seat 10 is made of high-temperature resistant heat-insulating material to reduce the evaporation of heat inside the titanium ingot melting furnace.

[0038] Both the ash baffle 20 and the handle 21 are made of high-temperature resistant heat-insulating material to reduce the evaporation of heat in the titanium ingot smelting furnace.

[0039] In this invention, the cover plate seat 10 is placed at the furnace opening of the titanium ingot smelting furnace. The ingot inlet / outlet 12 on the cover plate seat 10 is opposite to the furnace opening of the titanium ingot smelting furnace. When titanium ingots need to be added into the titanium ingot smelting furnace, the handle 21 on one of the ash-blocking gates 20 is pulled outward. Through the transmission component 30, the other ash-blocking gate 20 can be moved synchronously, so that the two ash-blocking gates 20 are separated, thereby exposing the ingot inlet / outlet 12. Titanium ingots can be easily added into the titanium ingot smelting furnace through the ingot inlet / outlet 12. After completion, the handle 21 on one of the ash-blocking gates 20 is pulled inward, so that the two ash-blocking gates 20 come closer to each other and abut against each other, thereby covering the ingot inlet / outlet 12. This effectively prevents the smoke and ash in the titanium ingot smelting furnace from escaping from the ingot inlet / outlet 12, and has a good dust-blocking effect.

[0040] like Figure 1 As shown, lifting rings 14 are fixed to the upper and lower parts of the front side of the cover plate seat 10, and to the left and right parts.

[0041] In this utility model, the lifting ring 14 on the cover plate seat 10 facilitates the lifting of the dust-blocking cover plate, thereby making it easier to clean and replace the dust-blocking cover plate.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
