[0002] The smelting furnace lining coating means coating a layer of refractory material on the inner wall of the smelting furnace to form a lining for protecting the furnace body. The lining is used to protect the furnace components from the extremely high heat generated during the smelting process, prevent the heat dissipation in the furnace, protect the furnace body from the erosion of high temperature, molten metal and slag, so as to make the smelting process of the smelting furnace more efficient.

[0003] The lining coating material is composed of refractory powder, binder and water, and has good plasticity and adhesion. During the coating process of the lining, the lining coating material is usually manually applied to the inner surface of the furnace with a trowel or a scraper. The problems encountered in practice are that the manual coating of the lining will cause uneven coating surfaces of the inner lining due to reasons such as the technical proficiency of personnel and non-standard operations, resulting in uneven heating of the lining. In the areas with thinner coating, heat stress concentration is likely to occur, cracks are easily generated, and the service life of the lining is shortened. Due to local overheating, heat stress concentration and reduced wear resistance, the lining is easily damaged and needs to be frequently replaced, thus affecting the production efficiency of the smelting furnace. Content of the Utility Model

A scraping plate 612 is connected to the side wall of the vertical rod 611.

[0033] In the above embodiment, a bracket 2 and a boss 3 are respectively arranged on the upper end surface of the bottom plate 1. A fixing groove 31 is formed on the upper end surface of the boss 3, and the furnace body 4 of the smelting furnace is placed in the fixing groove 31. The fixing groove 31 is used to fix and limit the furnace body, preventing the furnace body from tipping over during the lining coating process, which is beneficial to improving the safety of the coating work. A first motor 21 is installed on the top of the bracket 2, and a rotating shaft 211 is rotatably installed on the top of the bracket 2. The output end of the first motor 21 is in transmission connection with one end of the rotating shaft 211, and a rotating block 212 is installed at the other end of the rotating shaft 211.

Control the first telescopic rod 5 to extend to lower the mold shell 51 into the furnace body 4 of the smelting furnace. A cavity is formed between the outer wall of the mold shell 51 and the inner wall of the furnace body.

Control the first telescopic rod 5 to contract to lift the mold shell 51 out of the smelting furnace 4. The first motor 21 drives the rotating shaft 211 to drive the rotating block 212 to rotate, and turn the second telescopic rod 6 to directly above the smelting furnace 4.

[0034] In one embodiment of the present application, referring to Figure 5 As shown, the driving device 7 includes a fixing frame 71. The top of the fixing frame 71 is connected to the end surface of the telescopic end of the second telescopic rod 6. A second motor 72 is installed in the fixing frame 71, and the output end of the second motor 72 is connected to the upper end surface of the turntable 61.

[0035] In the above embodiments, the second motor 72 installed in the fixed frame 71 can drive the turntable 61 to rotate. The fixed frame 71 is used to fixedly install the second motor 72, which is beneficial to improving the stability of the rotation of the turntable 61, and further enables the scraping plate 612 to scrape stably in the furnace body of the smelting furnace 4, and thus is beneficial to improving the uniformity of the coating of the furnace lining material.

[0036] In one embodiment of the present application, refer to Figure 4 As shown, two vertical rods 611 are provided on the upper end surface of the turntable 61, and the two vertical rods 611 are symmetrically arranged on the turntable 61 respectively.

[0037] In the above embodiments, the two vertical rods 611 are symmetrically arranged on the turntable 61 respectively, which can play a balancing role, making the turntable 61 drive the vertical rods 611 to rotate more smoothly, and further improving the stability of the scraping plate 612 when scraping the furnace lining coating material.

[0038] In one embodiment of the present application, the vertical rod 611 is rotatably connected to the turntable 61 through a damping rotating shaft.

[0039] In the above embodiments, the vertical rod 611 is rotatably connected to the upper end surface of the turntable 61. The rotation angle of the scraping plate 612 connected to the side wall of the vertical rod 611 can be adjusted by rotating the vertical rod 611, and then the scraping range of the scraping plate 612 in the furnace body during rotation can be controlled. By controlling the scraping range of the scraping plate 612, the thickness of the furnace lining coating layer can be controlled, which is beneficial to improving the coating flexibility of the coating device. The rotation connection through the damping rotating shaft facilitates the rotation of the vertical rod 611 to achieve a stop at any angle, and is convenient for positioning and adjusting the direction of the scraping plate 612.

[0042] In one embodiment of the present application, refer to Figure 2 As shown, an anti-sticking layer 511 is provided on the outer wall of the mold shell 51.

[0043] In the above embodiments, an anti-sticking layer 511 is provided on the outer wall of the formwork 51. The anti-sticking layer 511 is used to prevent the furnace lining coating material from adhering to the outer wall of the formwork 51 when the formwork 51 is lifted, resulting in the defect of the furnace lining coating material, which is beneficial to improving the integrity of the adhesion of the furnace lining coating material in the furnace body. Preferably, the anti-sticking layer 511 can be selected as a Teflon coating PTFE, which has excellent high-temperature resistance, corrosion resistance and anti-sticking properties.

[0044] In an embodiment of the present application, referring to Figure 2 As shown, a mixing tank 8 is provided on the side of the bracket 2.

[0045] In the above embodiments, when preparing the proportion of the furnace lining coating material, insufficient stirring will cause lumps or agglomerates in the material, which will in turn cause uneven coverage of the furnace lining coating material. By putting the proportioned material into the mixing tank 8 for sufficient stirring to prevent the material from caking, it is beneficial to improve the uniformity of the furnace lining coating material.

[0046] During the actual use of the present application: control the first telescopic rod 5 to extend to lower the formwork 51 into the melting furnace 4 in the furnace body. A cavity is formed between the outer wall of the formwork 51 and the inner wall of the furnace body. Inject the furnace lining coating material into the cavity and wait for a period of time to allow the coating material to be preliminarily hardened so that the coating material is preliminarily attached to the inner wall of the furnace body. Control the first telescopic rod 5 to contract to lift the formwork 51 out of the melting furnace 4. Before lifting the formwork 51, the formwork 51 can be gently tapped. The vibration caused by the tapping facilitates the separation of the outer wall of the formwork 51 from the coating layer. The first motor 21 drives the rotating shaft 211 to drive the rotating block 212 to rotate, and the second telescopic rod 6 is rotated to directly above the melting furnace 4. Control the second telescopic rod 6 to extend to lower the turntable 61 into the melting furnace 4. The telescopic end of the second telescopic rod 6 is rotationally connected to the turntable 61 through the driving device 7. The driving device 7 drives the turntable 61 to slowly rotate in the melting furnace 4. The bottom surface of the turntable 61 contacts the furnace lining coating material attached to the bottom of the melting furnace 4. When the bottom surface of the turntable 61 rotates, it can evenly level the furnace lining coating material attached to the bottom of the melting furnace 4. A vertical rod 611 is installed on the upper end surface of the turntable 61, and a scraping plate 612 is connected to the side wall of the vertical rod 611. The scraping plate 612 contacts the furnace lining coating material on the inner side wall of the melting furnace 4. The turntable 61 drives the scraping plate 612 to rotate in the melting furnace 4. When the scraping plate 612 moves in contact with the furnace lining coating material on the inner side wall of the melting furnace 4, it can level the surface of the furnace lining coating material on the inner side wall of the melting furnace 4. When the scraping plate 612 rotates, it can also scrape off the excess coating material.
