Description

A steel ingot mold inner wall cleaning device Technical Field

[0001] This invention relates to the field of iron and steel metallurgy technology, and in particular to a device for cleaning the inner wall of a steel ingot mold. Background Technology

[0002] Currently, in the domestic steel metallurgical industry, the main method for cleaning steel ingot molds is to use iron shovels to remove slag from the inner wall of the mold. However, this traditional method of manually cleaning slag has the following problems: cleaning steel ingot molds manually with iron shovels requires a lot of manpower and resources, resulting in high labor intensity; the dead corners on the inner wall of the ingot mold are difficult to clean manually, affecting the surface quality of subsequent steel ingots and increasing the cost of producing high-temperature alloy steel ingots. Therefore, it is necessary to adopt a highly efficient device or method for cleaning the inner wall of steel ingot molds to quickly and forcefully remove slag from the surface of the ingot mold and improve the surface quality of the steel ingots. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a steel ingot mold inner wall cleaning device, which solves the technical problems of high labor intensity and poor cleaning effect.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a steel ingot mold inner wall cleaning device, including a base, a feeding and pushing mechanism on the right side of the base, an automatic cleaning mechanism on the left side of the base, and a dust collection mechanism on the outside of the automatic cleaning mechanism;

[0005] The feeding and pushing mechanism includes an electric push rod fixedly connected to the base, a slide rod slidably connected to the output end of the electric push rod, a baffle fixedly connected to the end of the slide rod, a feeding frame fixedly connected to the other side wall of the baffle, and a positioning and clamping mechanism symmetrically provided on the outer side of the feeding frame.

[0006] The automatic cleaning mechanism includes a motor fixedly connected to the upper end of the base, a rotating column fixedly connected to the output end of the motor, multiple mounting sleeves fixedly connected at equal intervals along the side wall axis of the rotating column, and multiple flexible steel wire brushes fixedly connected at equal intervals in the radial direction of the mounting sleeves.

[0007] Preferably, the positioning and clamping mechanism includes two fixed cylinders symmetrically fixedly connected to the side wall of the baffle. A magnetic push rod is slidably installed on the inner side of the fixed cylinder. The end of the magnetic push rod extends into the interior of the feeding frame. A first spring is fixedly connected to the side wall of the magnetic push rod. A first electromagnet is fixedly connected to the other end of the first spring.

[0008] The magnetism of the first electromagnet is consistent with that of the magnetic push rod. The bottom sides of the feeding frame are symmetrically provided with limiting guide rails, which extend through the baffle.

[0009] Preferably, the automatic cleaning mechanism further includes a dust baffle plate sleeved on the outside of the rotating column, a second electromagnet is fixedly connected to the outer wall of the dust baffle plate, a second spring is fixedly connected to the outer end of the second electromagnet, an elastic sealing sleeve is provided on the outside of the second spring, and a flexible magnetic sleeve is fixedly connected to the other end of the elastic sealing sleeve.

[0010] The magnetism of the second electromagnet is consistent with that of the flexible magnetic sleeve, and the side wall of the flexible magnetic sleeve near the flexible wire brush is set as an arc surface;

[0011] Multiple bottom wall steel wires are fixedly connected to the side wall of the rotating column away from the dust baffle plate. The bottom wall steel wires are arranged at equal intervals along the radial direction of the rotating column.

[0012] The outer ends of the bottom wall steel wires are all fixedly connected to counterweight rings, and the bottom wall steel wires are designed with a continuous convex wave shape.

[0013] Preferably, the dust collection mechanism includes a collection box fixedly connected to the top of the base, a fan fixedly connected to the top of the collection box, and the collection box is located outside the motor;

[0014] The collection box is fixedly connected to the side wall near the dust baffle plate with a feed pipe, and the end of the feed pipe is fixedly connected to a conduit.

[0015] The conduit is configured as a flexible hose, and the other end of the conduit extends into the interior of the dust baffle.

[0016] By means of the above technical solution, the present invention provides a steel ingot mold inner wall cleaning device, which has at least the following beneficial effects:

[0017] 1. This invention enables rapid feeding of steel ingot molds to be cleaned through a feeding and pushing mechanism. Simultaneously, the lateral movement of the electric push rod, baffle, and feeding frame pushes the steel ingot molds to be cleaned to the cleaning station, effectively improving cleaning efficiency. Furthermore, the positioning and clamping mechanism enables stable clamping of steel ingot molds of different diameters, effectively reducing shaking during the cleaning process and further improving the cleaning efficiency of the inner wall of the steel ingot mold.

[0018] 2. This invention achieves comprehensive scraping and cleaning of the inner wall of the steel ingot mold through an automatic cleaning mechanism. During the cleaning of the steel ingot mold, the rotating column drives the flexible steel wire brush to remove slag and impurities from the inner wall of the steel ingot mold, which effectively improves the cleaning effect, increases the service life of the vacuum induction furnace steel ingot mold and the quality of the steel ingot products after smelting.

[0019] 3. The present invention uses an automatic cleaning mechanism to drive the rotating column and the bottom wall steel wire to rotate synchronously. During the rotation of the bottom wall steel wire, the centrifugal force drives the counterweight ring to continuously contact the bottom wall of the fixed mold, thereby achieving enhanced cleaning of the bottom wall and further improving the cleanliness of the bottom wall of the steel ingot mold.

[0020] 4. This invention achieves effective collection of dust from the inner wall of the steel ingot mold through a dust collection mechanism. At the same time, through the coordinated arrangement of the fan, duct and feed pipe, it achieves effective collection of dust, slag and impurities from the cleaning of the inner wall of the steel ingot mold, realizing dust-free operation and green environmental protection.

[0021] 5. This invention effectively isolates dust inside the steel ingot mold by using a dust baffle plate. At the same time, the combination of the second electromagnet, the elastic sealing sleeve, and the flexible magnetic sleeve enhances the sealing of dust inside the steel ingot mold, effectively reducing dust overflow and minimizing the harm of dust to operators.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] Please refer to Figures 1-2. A steel ingot mold inner wall cleaning device includes a base 1, a feeding and pushing mechanism 2 on the right side of the base 1, an automatic cleaning mechanism 3 on the left side of the base 1, and a dust collection mechanism 4 on the outside of the automatic cleaning mechanism 3.

[0035] The feeding and pushing mechanism 2 includes an electric push rod 20 fixedly connected to the base 1. A slide rod 21 is slidably connected to the output end of the electric push rod 20. A baffle 22 is fixedly connected to the end of the slide rod 21. A feeding frame 23 is fixedly connected to the other side wall of the baffle 22. A positioning and clamping mechanism 24 is symmetrically arranged on the outer side of the feeding frame 23. Before the mold cleaning begins, the electric push rod 20 is first activated, moving the baffle 22 to the left or right side. Then, the side wall of the ingot mold is clamped inside the feeding frame 23. The electric push rod 20 is then activated again to achieve the lateral pushing of the baffle 22. When the 22 reaches the cleaning station, the electric push rod 20 is turned off. At this time, the end side wall of the rotating column 31 is in contact with the bottom wall of the steel ingot mold. The feeding and pushing mechanism 2 realizes the rapid feeding of the steel ingot mold to be cleaned. At the same time, the lateral movement of the electric push rod 20, the baffle 22 and the feeding frame 23 pushes the steel ingot mold to be cleaned to the cleaning station, which effectively improves the cleaning efficiency. Meanwhile, the positioning and clamping mechanism 24 realizes the stable clamping of steel ingot molds of different diameters, which effectively reduces the shaking of the steel ingot mold during the cleaning process and further improves the cleaning efficiency of the inner wall of the steel ingot mold.

[0036] The automatic cleaning mechanism 3 includes a motor 30 fixedly connected to the upper end of the base 1. A rotating column 31 is fixedly connected to the output end of the motor 30. Multiple mounting sleeves 32 are fixedly connected at equal intervals along the side wall axis of the rotating column 31. Multiple flexible steel wire brushes 33 are fixedly connected at equal intervals in the radial direction of the mounting sleeves 32. After the end side wall of the rotating column 31 is in contact with the bottom wall of the ingot mold, the motor 30 is turned on, driving the rotating column 31 to rotate. The automatic cleaning mechanism 3 achieves comprehensive scraping and cleaning of the inner wall of the ingot mold. When cleaning the ingot mold, the rotation of the rotating column 31 drives the flexible steel wire brushes 33 to remove slag and impurities from the inner wall of the ingot mold, effectively improving the cleaning effect, increasing the service life of the vacuum induction furnace ingot mold and the quality of the smelted ingot products.

[0037] Example 2

[0038] Please refer to Figures 3-5. This embodiment is basically the same as Embodiment 1. This embodiment is made on the basis of Embodiment 1 and has the same beneficial effects as Embodiment 1. The same parts can be referred to each other, and will not be described in detail here.

[0039] The positioning and clamping mechanism 24 includes two fixed cylinders 240 symmetrically fixedly connected to the side wall of the baffle 22. A magnetic push rod 241 is slidably installed on the inner side of the fixed cylinder 240. The end of the magnetic push rod 241 extends into the interior of the loading frame 23. A first spring 242 is fixedly connected to the side wall of the magnetic push rod 241. A first electromagnet 243 is fixedly connected to the other end of the first spring 242. When the outer bottom wall of the ingot mold is engaged with the interior of the loading frame 23, the first electromagnet 243 is activated. Under the action of electromagnetic repulsion, the first spring 242 is extended, so that the side wall of the magnetic push rod 241 is tightly fitted with the outer wall of the ingot mold. The electromagnetic force is used to further enhance the clamping stability of the ingot mold.

[0040] As a preferred technical solution in this embodiment, the magnetism of the first electromagnet 243 and the magnetism of the magnetic push rod 241 are consistent, ensuring that the side wall of the magnetic push rod 241 is stably clamped to the outer wall of the steel ingot mold under the action of electromagnetic repulsion. The bottom sides of the feeding frame 23 are symmetrically provided with limiting guide rails 25, which extend through the baffle 22. While limiting the outer wall of the steel ingot mold, the limiting guide rails 25 also ensure the stable lateral movement of the baffle 22.

[0041] Example 3

[0042] Please refer to Figures 6-8. This embodiment is basically the same as Embodiment 1. This embodiment is made on the basis of Embodiment 1 and has the same beneficial effects as Embodiment 1. The same parts can be referred to each other, and will not be described in detail here.

An elastic sealing sleeve 343 is provided on the outside of the second spring 342, and a flexible magnetic sleeve 344 is fixedly connected to the other end of the elastic sealing sleeve 343. During the cleaning process of the inner wall of the steel ingot mold, the second electromagnet 341 is activated. Under the action of electromagnetic repulsion, the flexible magnetic sleeve 344 expands, thereby achieving a tight fit between the outer wall of the flexible magnetic sleeve 344 and the inner wall of the steel ingot mold. The dust baffle 34 effectively isolates the dust inside the steel ingot mold. At the same time, the cooperation between the second electromagnet 341, the elastic sealing sleeve 343, and the flexible magnetic sleeve 344 enhances the sealing of the dust inside the steel ingot mold, effectively reducing dust spillage and reducing the harm of dust to operators.

[0044] As a preferred technical solution in this embodiment, the magnetism of the second electromagnet 341 and the magnetism of the flexible magnetic sleeve 344 are consistent. The side wall of the flexible magnetic sleeve 344 near the flexible wire brush 33 is set as an arc surface to ensure that when the flexible magnetic sleeve 344 is in contact with the side wall of the steel ingot mold, the flexible magnetic sleeve 344 slides to the inner wall of the steel ingot mold.

[0045] As a preferred technical solution in this embodiment, a plurality of bottom wall steel wires 35 are fixedly connected to the side wall of the rotating column 31 away from the dust baffle plate 34. The bottom wall steel wires 35 are arranged at equal intervals along the radial direction of the rotating column 31. The rotating column 31 and the bottom wall steel wires 35 are driven to rotate synchronously by the automatic cleaning mechanism 3. During the rotation of the bottom wall steel wires 35, the counterweight ring 36 is driven to continuously contact the bottom wall of the fixed mold under the action of centrifugal force, thereby achieving enhanced cleaning of the bottom wall and further improving the cleanliness of the bottom wall of the steel ingot mold.

[0046] As a preferred technical solution in this embodiment, a counterweight ring 36 is fixedly connected to the outer end of the bottom wall steel wire 35. The bottom wall steel wire 35 is set as a continuous convex wave shape to ensure that the bottom wall steel wire 35 is in full contact with the inner bottom wall of the steel ingot mold during the rotation and expansion process, so as to achieve thorough cleaning of the bottom wall of the steel ingot mold.

[0049] The dust collection mechanism 4 includes a collection box 40 fixedly connected to the top of the base 1. A fan 43 is fixedly connected to the top of the collection box 40. The collection box 40 is located outside the motor 30. A feed pipe 41 is fixedly connected to the side wall of the collection box 40 near the dust baffle 34. A conduit 42 is fixedly connected to the end of the feed pipe 41. When cleaning the ingot mold, the fan 43 is turned on to suck the dust inside the ingot mold into the collection box 40.

[0050] As a preferred technical solution in this embodiment, the conduit 42 is configured as an elastic hose, and the other end of the conduit 42 extends into the interior of the dust baffle 34. The dust collection mechanism 4 effectively collects the dust from the inner wall of the steel ingot mold. At the same time, the coordinated arrangement between the fan 43, the conduit 42 and the feed pipe 41 effectively collects the dust, slag and impurities from the inner wall of the steel ingot mold, achieving dust-free operation and environmental protection.
