Description

Technical Field

[0001] This utility model relates to the field of furnace slag cleaning technology, and in particular to a slag cleaning device for industrial furnaces. Background Technology

[0002] A smelting furnace is a device that melts metal ingots and some scrap metals, adds necessary alloying components, and then melts them into the desired alloy through operations such as slag removal and refining. Smelting furnaces can be divided into fuel-heated and electric-heated types according to their heating energy. After the smelting furnace has been working, it will produce slag, which reduces the quality of the molten metal. Therefore, it is necessary to separate the slag from the molten metal.

[0003] Currently, the cleaning of molten slag and bottom slag is usually done by workers using slag scraping tools. However, the temperature inside the smelting furnace is very high when it is running. During the slag removal and refining process, workers need to open the furnace door multiple times, hold the slag scraping tools and reach into the furnace to scrape off the slag. This not only increases the intensity of manual labor, but also increases the risk of workers being harmed by high temperatures and harmful substances.

[0004] Based on the above, this utility model proposes a slag removal device for industrial furnaces. Summary of the Invention

[0005] In order to overcome the shortcomings of existing slag removal and refining processes, which increase the intensity of manual labor and increase the harm to workers from high temperatures and harmful substances, this utility model proposes a slag removal device for industrial furnaces.

[0006] The technical solution of this utility model is: a slag cleaning device for an industrial furnace, comprising a furnace body, a baffle, a motor, a cover plate, a sliding frame, a handle, and a push plate. The motor is installed at the bottom of the furnace body, and the output shaft on the upper side of the motor is connected to the baffle via a coupling. The cover plate is placed on the furnace body. The sliding frame is slidably connected inside the furnace body, and the handle is slidably connected inside the sliding frame. The push plate is fixedly connected to the rear side of the handle, and the push plate contacts the bottom wall of the sliding frame.

[0007] In one embodiment, the system further includes an electric slide rail, a sliding frame, a first scraper, a second scraper, a collection frame, and a ceramic float. Electric slide rails are installed on both the front and rear sides of the bottom of the cover plate. A sliding frame is slidably connected between the electric slide rails on the front and rear sides. A first scraper is fixedly connected to both the front and rear sides of the sliding frame. The first scraper is slidably connected to the front and rear inner walls of the furnace body. A second scraper is slidably connected vertically to the lower part of the sliding frame. A collection frame is fixedly connected to the second scraper. A ceramic float is fixedly connected to the lower part of the collection frame.

[0008] In one embodiment, the device further includes a container, a guide frame, an alignment plate, a sliding plate, a first spring, and a second spring. The container is fixedly attached to the cover plate. Guide frames are fixedly attached to both the front and rear sides of the bottom of the container. An alignment plate is slidably connected between the front and rear guide frames. Symmetrically distributed second springs are connected between the front and rear sides of the alignment plate and the adjacent guide frames. Sliding plates are slidably connected to both the front and rear sides of the alignment plate. A first spring is connected between the sliding plates on both the front and rear sides and the alignment plate.

[0009] In one embodiment, both the sliding frame and the sliding plate are press-fitted together.

[0010] In one embodiment, handles are provided on the left and right sides of the top of the cover plate and on the left and right sides of the front of the sliding frame.

[0011] In one embodiment, the bottom wall of the sliding frame is provided with a high-temperature resistant filter.

[0012] This invention has the following advantages: First, the molten slag is cleaned by the second scraper, and then the slag at the bottom of the furnace is removed by the sliding frame and the pusher plate, thereby improving the quality and purity of the molten metal and ensuring the production of high-quality metal products.

[0013] This invention utilizes a sliding frame, a sliding plate, and an alignment plate to automatically allow the slag-forming agent in the container to fall into the furnace, thereby accelerating the formation of slag in the molten metal and improving the purity and quality of the metal.

[0022] The present invention will now be described in detail with reference to the accompanying drawings. Example

[0023] A slag removal device for an industrial furnace, such as Figure 1 , Figure 2 and Figure 3 As shown, the furnace includes a furnace body 1, a baffle 1001, a motor 1002, a cover plate 2, a sliding frame 3, a handle 4, and a push plate 5. The bottom wall of the furnace body 1 has a liquid outlet hole. The motor 1002 is installed at the bottom of the furnace body 1. The output shaft on the upper side of the motor 1002 is connected to the baffle 1001 through a coupling. The baffle 1001 is used to control the opening and closing of the liquid outlet hole. The cover plate 2 is flipped onto the furnace body 1. The sliding frame 3 is slidably connected to the furnace body 1. The bottom wall of the sliding frame 3 is provided with a high-temperature resistant filter screen. The handle 4 is slidably connected to the sliding frame 3. The push plate 5 is fixed to the rear side of the handle 4 and contacts the bottom wall of the sliding frame 3. Handles are provided on the left and right sides of the top of the cover plate 2 and on the left and right sides of the front side of the sliding frame 3.

[0024] like Figure 4 and Figure 5 As shown, it also includes an electric slide rail 6, a sliding frame 7, a first scraper 8, a second scraper 9, a collection frame 10, and a ceramic float 11. There are two electric slide rails 6, which are respectively installed on the front and rear sides of the bottom of the cover plate 2. The sliding frame 7 is slidably connected between the two electric slide rails 6. The first scraper 8 is fixedly connected to both the front and rear sides of the sliding frame 7. The first scraper 8 is slidably connected to the front and rear inner walls of the furnace body 1. The second scraper 9 is slidably connected to the lower part of the sliding frame 7 along the vertical direction. The collection frame 10 is fixedly connected to the second scraper 9. The ceramic float 11 is fixedly connected to the lower part of the collection frame 10.

[0025] When using this device, the operator first removes the cover plate 2, puts the scrap metal to be melted into the furnace body 1, and puts the cover plate 2 back in its original position. Then, the operator controls the operation of the furnace body 1. The metal in the furnace body 1 will melt into liquid metal. As the melting time increases, impurities in the metal will float on the surface of the liquid metal or settle on the filter screen of the sliding frame 3. At this time, the electric slide rail 6 can be controlled to move the sliding frame 7 to the right, thereby moving the first scraper 8, the second scraper 9, the collection frame 10 and the ceramic float 11 to the right together. The second scraper 9, which moves to the right, will scoop the slag into the collection frame 10, and the first scraper 8, which moves to the right, will scrape off the slag adhering to the inner walls of the front and rear of the furnace body 1, so as to prevent the slag from gradually accumulating and forming a thick layer on the inner wall of the furnace body 1, which will not only affect the melting efficiency, but may also damage the furnace body.

[0026] After smelting is completed, the furnace body 1 is stopped, and then the motor 1002 drives the baffle 1001 to rotate. The molten metal in the furnace body 1 is discharged from the outlet. When the temperature inside the furnace body 1 drops to a suitable level, the sliding frame 3 is pulled out of the furnace body 1. The collection bucket for collecting bottom slag is placed below the sliding frame 3. Then, the handle 4 is pulled forward, which drives the push plate 5 to move forward. The forward-moving push plate 5 scrapes the bottom slag on the sliding frame 3 into the collection bucket. After cleaning, the handle 4 and the sliding frame 3 are pushed back to their original positions. In summary, the molten slag is first cleaned by the second scraper 9, and then the bottom slag is removed by the sliding frame 3 and the push plate 5, thereby improving the quality and purity of the molten metal and ensuring the production of high-quality metal products. Example

[0027] Based on Example 1, such as Figure 1 , Figure 6 and Figure 7 As shown, it also includes a container 12, a guide frame 13, an alignment plate 14, a sliding plate 141, a first spring 142, and a second spring 15. The container 12, which is used to hold the slag-forming agent, is fixed to the cover plate 2. The bottom of the container 12 has twelve discharge holes evenly opened. There are two guide frames 13, which are fixed to the front and rear sides of the bottom of the container 12 respectively. The alignment plate 14 is slidably connected between the two guide frames 13. The alignment plate 14 is used to control the opening and closing of the discharge holes. There are twelve leakage holes evenly opened on the alignment plate 14. Two second springs 15 are connected between the front and rear sides of the alignment plate 14 and the adjacent guide frame 13. There are two sliding plates 141, which are slidably connected to the front and rear sides of the alignment plate 14 respectively. The first spring 142 is connected between the two sliding plates 141 and the alignment plate 14. The sliding frame 7 and the sliding plate 141 are in a pressing fit.

[0028] Initially, a suitable amount of slag-forming agent is loaded into container 12. When the sliding frame 7 moves to the right and contacts the sliding plate 141, the sliding frame 7 will drive the alignment plate 14 to move to the right through the sliding plate 141. The second spring 15 will deform. When the discharge hole of the alignment plate 14 is aligned with the discharge port of container 12, the slag-forming agent in container 12 will fall into the furnace body 1. The slag-forming agent can accelerate the formation of slag in the molten metal, thereby improving the purity and quality of the metal. When the second spring 15 deforms to its limit, as the sliding frame 7 continues to move to the right, the sliding frame 7 will squeeze the sliding plate 141 to move inward. The first spring 142 will deform. When the sliding frame 7 moves to the right and passes the sliding plate 141, under the elastic action of the first spring 142 and the second spring 15, the sliding plate 141 moves outward to reset. The alignment plate 14 then drives the sliding plate 141 to move to the left to reset.
