Description

Technical Field

[0001] The present application relates to the field of non-ferrous metal smelting equipment technology, and in particular to a cooling type slag removal device and a slag removal process for non-ferrous metal smelting. Background Art

[0002] The smelting process for nonferrous metals generally involves smelting and melting the raw materials, followed by alloying. Melting nonferrous metal ingots into molten metal takes place at high temperatures in large smelting furnaces. Because unmelted nonferrous metal ingots are typically of lower purity and contain more impurities, some impurities settle in the furnace during the refining process, while some slag floats on the surface of the molten metal. This slag must be skimmed and purified, otherwise the slag will flow out when the molten metal is poured or drained, seriously affecting the usability of castings.

[0003] In the related art, impurities on the surface of the molten metal are generally removed manually. When skimming slag, an iron scraper is used to operate at the furnace mouth. The scraper handle is manually held and pushed and pulled back and forth in the molten metal to allow impurities to enter the colander, and then the scraper is removed from the smelting furnace.

[0004] Regarding the above-mentioned related technologies, during manual slag removal operations, the temperature of the furnace gas ejected from the furnace to the outside is as high as several hundred degrees, and the working environment of the workers is very harsh; and the slag removal efficiency of the manual slag removal operation method using a scraper is relatively low, and the slag removal effect is not good. Summary of the Invention

[0005] In order to solve the problems of high labor intensity, low efficiency and poor effect of slag scraping during slag scraping operations in related technologies, the present application provides a cooling slag scraping device and a slag scraping process for non-ferrous metal smelting.

[0006] In the first aspect, the present application provides a cooling type slag removal device for non-ferrous metal smelting, which adopts the following technical solution:

[0007] A cooling type slag skimming device for nonferrous metal smelting, comprising a base, a support assembly, a slag skimming plate and a cooling assembly;

[0008] A socket for connecting with a forklift is provided on one side of the base;

[0009] The support assembly is located on the base, and the support assembly is used to drive the skimmer plate to rise and fall;

[0010] The skimmer pan is connected to the support assembly, and a cooling cavity for introducing a cooling medium is provided inside the skimmer pan;

[0011] The cooling assembly is communicated with the cooling cavity of the skimmer pan, and the cooling assembly is used for circulating a cooling medium into the cooling cavity.

[0012] By adopting the above technical solution, during the slag removal operation, the fork of the forklift is inserted into the socket on one side of the base, and then the slag removal device is moved to the side of the smelting furnace by the forklift, and then the support assembly is used to drive the slag removal plate to rise and fall until the slag removal plate contacts the surface of the molten metal in the smelting furnace, and then the cooling assembly is used to circulate the cooling medium into the cooling chamber, and the impurities on the surface of the molten metal form a layer of fixed metal shell mixed with impurities after cooling and adhere to the slag removal plate, and then the support assembly is used to drive the slag removal plate to separate from the molten metal, and after a period of rest, when the solid metal shell mixed with impurities is completely solidified, the cooling assembly is closed, and then the support assembly is used to move the slag removal plate to the outside of the smelting furnace, thus completing the slag removal operation. The above slag removal device does not require manual use of scrapers for slag removal, thereby effectively reducing the labor intensity of workers, and the cooling of the slag removal plate can form a solid metal layer on the surface of the molten metal, and a single slag removal operation can completely remove all impurities on the surface of the molten metal, which not only has a good slag removal effect, but also has a high slag removal efficiency.

[0013] Optionally, the support assembly includes a support rod, a horizontal rod and an operating rod, one end of the support rod is connected to the base and the other end is connected to the horizontal rod, one end of the operating rod is connected to one end of the horizontal rod away from the support rod, and the other end is fixedly connected to the slag plate.

[0014] By adopting the above technical solution and setting up the support assembly of the above structure, workers can drive a forklift to operate at a distance from the smelting furnace, avoiding burns to workers caused by high temperature and splashing molten metal, and effectively improving the safety of the slag scraping device during use; and the above support assembly can enhance the overall strength of the slag scraping device, which is conducive to extending the service life of the slag scraping device.

[0015] Optionally, the support rod includes a sleeve and a sliding rod coaxially slidably connected to the sleeve, one end of the sleeve is fixedly connected to the base, one end of the sliding rod is coaxially slidably connected to the sleeve, and the other end is fixedly connected to the end of the horizontal rod, and the base is provided with a first cylinder for driving the sliding rod to lift and slide.

[0016] By adopting the above technical solution, when it is necessary to drive the slag plate to rise and fall, the first cylinder is started, and the piston rod of the first cylinder drives the slide rod to rise and fall, and the slide rod drives the horizontal rod to rise and fall when it is raised and lowered, and the horizontal rod drives the operating rod to rise and fall when it is raised and lowered, thereby driving the slag plate to rise and fall, so that the slag plate can contact the metal liquid surface at different heights in the smelting furnace, thereby effectively enhancing the applicability of the slag stripping device.

[0017] Optionally, the end of the operating rod facing away from the slag plate is rotatably connected to the horizontal rod, and the support assembly also includes a driving member for driving the operating rod to rotate. The end of the slag plate facing away from the operating rod is provided with a plurality of slag plates, and the plurality of slag plates are evenly distributed along the circumference of the slag plate and fixedly connected to the slag plate. The slag plates are perpendicular to the bottom surface of the slag plate, the long side direction of the slag plates is consistent with the radial direction of the slag plate, and the width of the slag plates gradually decreases in the direction away from the center of the slag plate.

[0018] By adopting the above technical solution, during the slag skimming operation, the operating lever is rotated by the driving member. The rotation of the operating lever drives the rotation of the slag skimming plate, which in turn drives the rotation of the multiple slag skimming plates. The rotation of the slag skimming plates stirs the surface of the molten metal, thereby forming an inverted cone-shaped vortex at the center of the molten metal surface. This encourages impurities on the surface of the molten metal to flow and gather toward the center of the slag skimming plate. After the surface molten metal solidifies, all impurities are entrained in the solid metal shell, thereby facilitating the complete removal of impurities from the surface of the molten metal. The provision of the slag skimming plates to stir the surface of the molten metal encourages impurities on the surface of the molten metal to flow and gather toward the center of the slag skimming plate, thereby making the slag skimming device suitable for smelting furnaces of different sizes and expanding its applicability. The slag skimming plates also increase the contact area between the solidified solid metal shell and the slag skimming plate, thereby helping to firmly adhere the solid metal shell containing impurities to the bottom of the slag skimming plate, thereby preventing the solid metal shell containing impurities from falling off the slag skimming plate and enhancing the reliability of the slag skimming device.

[0019] Optionally, the driving member includes a driving motor, a driving gear and a driving gear ring, the housing of the driving motor is fixedly connected to the horizontal rod, the driving gear is coaxially fixedly connected to the output shaft of the driving motor, the driving gear ring is coaxially sleeved on the operating rod and fixedly connected to the operating rod, and the driving gear ring is engaged with the driving gear.

[0020] By adopting the above technical solution, when the scraper plate needs to be driven to rotate, the drive motor is started, and the output shaft of the drive motor drives the driving gear to rotate, and the driving gear rotates, which drives the driving ring gear to rotate, and the driving ring gear rotates, which drives the operating lever to rotate, thereby driving the scraper plate to rotate. The above driving member has the advantages of easy maintenance and reliable transmission.

[0021] Optionally, the cooling assembly includes a water tank, a water pump, a water inlet pipe and a water outlet pipe. The water tank is fixedly connected to the horizontal rod, one end of the water inlet pipe is fixedly connected to the water tank, and the other end is passed through the operating rod and connected to the cooling chamber. The water pump is located at one end of the water inlet pipe close to the water tank and is fixedly connected to the water inlet pipe. The water outlet pipe is passed through the operating rod, one end of the water outlet pipe is fixedly connected to the skimmer plate, and the other end extends outside the operating rod.

[0022] By adopting the above technical solution, during the slagging process, the water pump is started, and the water pump transports the cooling water in the water tank to the cooling chamber of the slagging plate through the water inlet pipe, thereby cooling the impurities on the surface of the molten metal. The cooling water is then discharged out of the cooling chamber through the water outlet pipe, thereby forming a continuous circulation cooling in the cooling chamber, so that the impurities on the surface of the molten metal solidify to form a metal shell; using water as a cooling medium has the advantages of good fluidity and large heat capacity, and has a good cooling effect, thereby shortening the time consumed in slagging, which is conducive to improving the slagging efficiency.

[0023] Optionally, it also includes a slag removal component, which includes a slag removal plate and a second cylinder. The slag removal plate is coaxially sleeved on the operating rod and is slidably connected to the operating rod. The second cylinder is used to drive the slag removal plate to slide. The slag removal plate is fixedly connected to a side close to the slag plate with multiple slag removal rods. The slag removal plate is penetrated by a plurality of reserved holes matching the slag removal rods, and the reserved holes are not connected to the cooling chamber.

[0024] By adopting the above technical solution and setting a reserved hole, a metal column integrally connected to the solid metal shell can be formed in the reserved hole during the slag removal process. After the slag removal operation is completed, the slag removal device is moved to the scrap steel pit by a forklift, and then the second cylinder is started. The second cylinder drives the slag removal plate to slide toward the slag removal pan. When the slag removal plate slides, it drives the slag removal rod to be inserted into the reserved hole. The slag removal rod squeezes the metal column in the reserved hole, thereby separating the solid metal shell adhered to the bottom of the slag removal pan from the slag removal pan. The separated solid metal shell mixed with impurities falls into the scrap steel pit so that the solid metal shell can be recycled for a second time. The above-mentioned slag removal component facilitates the separation of the solid metal shell adhered to the bottom of the slag removal pan from the slag removal pan, thereby improving the practicality of the slag removal device.

[0025] In a second aspect, the present application further provides a cooling slag removal process for non-ferrous metal smelting, which uses the above-mentioned cooling slag removal device for non-ferrous metal smelting, and includes the following steps:

[0026] S1: Insert the fork of the forklift into the socket on one side of the base, and then use the forklift to move the slag skimmer to the side of the smelting furnace;

[0027] S2: Use the support assembly to drive the slag plate to rise and fall until the slag plate contacts the surface of the molten metal in the smelting furnace; then use the cooling assembly to circulate the cooling medium into the cooling chamber until a layer of solid metal shell mixed with impurities solidifies at the bottom of the slag plate, and then use the support assembly to drive the slag plate to separate from the molten metal. After standing for 3-5 minutes, close the cooling assembly to complete the slag removal operation.

[0028] By adopting the above technical solution, a solid metal shell is formed on the surface of the molten metal through cooling, and the solid metal shell wraps up the impurities on the surface of the molten metal, thereby completing the slag removal operation. All impurities on the surface of the molten metal can be removed in one slag removal operation, which not only has a good slag removal effect, but also has a high slag removal efficiency.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. The present invention uses a cooled slag skimmer to form a solid metal layer on the surface of the molten metal and adhere to the slag skimmer. A single slag skimmer operation can completely remove all impurities on the surface of the molten metal. This not only provides a good slag skimming effect but also a high slag skimming efficiency. In addition, the slag skimmer of the present invention does not require manual slag skimming with a skimmer, thereby effectively reducing the labor intensity of workers.

[0031] 2. The present application provides a rotating slag plate and a slag plate at the bottom of the slag plate. During the slag removal operation, the operating rod is driven to rotate by a driving member. When the operating rod rotates, the slag plate is driven to rotate. The slag plate drives multiple slag plates to rotate. When the slag plates rotate, the surface of the molten metal is stirred, so that an inverted cone-shaped vortex is formed at the center of the molten metal surface. This is conducive to the impurities on the surface of the molten metal flowing to the center of the slag plate. After the surface molten metal solidifies, all impurities can be mixed in the solid metal shell, which is conducive to removing all impurities on the surface of the molten metal.

[0032] 3. The present application provides a slag removal assembly to facilitate separation of the solid metal shell adhered to the bottom of the slag skimmer pan from the slag skimmer pan, thereby improving the practicality of the slag skimmer device. BRIEF DESCRIPTION OF THE DRAWINGS
