Description

Technical Field

[0001] This application relates to the technical field of smelting furnaces, and in particular to a metal smelting furnace. Background Art

[0002] A smelting furnace refers to equipment that melts metal ingots and some scrap metals, adds necessary alloy components, and melts them into the required alloys through operations such as slag skimming and refining.

[0003] The metal smelting furnace mentioned in the existing Chinese patent (authorization announcement number: CN218583756U) includes a smelting component and an exhaust gas treatment component. The smelting component includes a base, a support plate, a smelting box, a smelting furnace body, a heater, and a circulation fan. The support plate is installed on the top of the base, and the smelting box is installed on one side of the support plate. The exhaust gas treatment component includes a driving member, a furnace cover, a filter box, a filter screen, and an exhaust pipe. The driving member is installed on the top of the support plate. By setting the base, the support plate, the smelting box, the smelting furnace body, the heater, and the circulation fan, the hot air inside the box can be circulated to increase the air flow and make the heat more uniform. By setting the driving member, the furnace cover, the filter box, the filter screen, and the exhaust pipe, the smelting furnace body can be opened and closed, and at the same time, the exhaust gas generated during the metal smelting process can be effectively filtered to reduce pollution.

[0004] When the metal smelting furnace is in use, it is used for melting metal ingots and some scrap metals. By adding necessary alloy components during the smelting process, it is convenient to smelt the required alloy metals and facilitate the production of the smelting furnace. However, a large amount of exhaust gas is generated during the use of the smelting furnace. In order to treat the exhaust gas, a filter screen is usually set to filter the exhaust gas. However, when the filter screen filters particulate matters such as soot and debris, the filter holes are easily blocked by the particulate matters, which in turn easily affects the filtration efficiency and treatment effect of the exhaust gas, and affects the service life of the filter screen and the operation of the smelting furnace. Summary of the Utility Model

[0005] The purpose of this application is to solve the problem that when the filter screen filters particulate matters such as soot and debris, the filter holes are easily blocked by the particulate matters, which in turn easily affects the filtration efficiency and treatment effect of the exhaust gas, and affects the service life of the filter screen and the operation of the smelting furnace. This application provides a metal smelting furnace.

[0006] The following specific technical solutions are adopted in this application to achieve the above purpose:

[0007] A metal smelting furnace includes a machine body. One side of the machine body is fixedly provided with a first motor. The output end of the first motor extends into the machine body and is fixedly connected to a smelting furnace body. One end of the smelting furnace body far from the first motor is rotatably connected to the machine body. The smelting furnace body is provided with a discharge port. A cover plate is installed on the smelting furnace body, and the cover plate corresponds to the discharge port. Two symmetric hydraulic telescopic rods are fixedly provided at the upper end of the machine body. The telescopic end of the hydraulic telescopic rod is fixedly connected to a support plate. Two connecting plates are fixedly connected between the support plate and the cover plate. A filter box is fixedly provided on the support plate. A motor is fixedly provided inside the filter box.

One side of the exhaust pipe far from the cover plate is fixedly connected to the filter box. The fan blade corresponds to the exhaust pipe. A box plate is installed at one end of the filter box far from the exhaust pipe. A fixed pipe is fixedly provided on the box plate. A cleaning mechanism is arranged between the filter box and the support plate.

[0008] By adopting the above technical solution, the situation of filter screen blockage is reduced through the cleaning mechanism, the influence on the filtering efficiency and filtering effect of the filter screen is reduced, the number of times of replacing and maintaining the filter screen is reduced, the service life of the filter screen is improved, and the operation of the smelting furnace is facilitated.

[0009] Further, the cleaning mechanism includes a second motor fixed on the filter box. The output end of the motor extends into the filter box and is fixedly connected to a screw rod. A moving plate is threadedly connected to the screw rod. A limiting component is arranged between the moving plate and the filter box.

[0010] By adopting the above technical solution, the motor drives the screw rod to rotate, and the rotation of the screw rod makes the moving plate move, providing power for the movement of the cleaning plate.

[0011] Further, the limiting component includes a limiting column fixed inside the filter box. The limiting column slidably penetrates the moving plate. The limiting column is located at the end of the moving plate far from the screw rod. A cleaning plate is arranged on the side surface of the moving plate. A cleaning part is arranged between the cleaning plate and the support plate.

[0012] By adopting the above technical solution, the moving plate drives the cleaning plate and the cleaning brush to move. The moving plate slides on the limiting column to limit the moving plate.

[0013] Further, the cleaning part includes cleaning brushes fixed on the cleaning plate and distributed in an array. The cleaning brushes are in contact with the filter screen. A collection box is arranged at the lower end of the filter box. The collection box extends out of the filter box and penetrates the support plate. The collection box corresponds to the filter screen.

[0014] By adopting the above technical solution, the cleaning plate and the cleaning brush move to clean the particulate matters such as dust and debris on the filter screen. The cleaned particulate matters enter the collection box as the cleaning brush moves, and the debris and dust are collected.

[0015] Furthermore, the filter box and the collection box are fixedly connected by bolts. One end of the filter screen extends out of the filter box, and the filter screen and the filter box are fixedly connected by bolts.

[0016] By adopting the above technical solution, turn the bolts on the collection box to release the restriction on the collection box, and then turn the bolts on the filter screen to pull out the filter screen, so as to clean and replace the collection box and the filter screen.

[0019] Furthermore, the connecting pipe is a metal telescopic pipe. Two symmetrical support columns are fixed on the machine body. The support columns penetrate through the support plate, and the support plate is located on one side of the hydraulic telescopic rod.

[0020] By adopting the above technical solution, since the connecting pipe is a metal telescopic pipe, it is convenient for the cover plate to move. When the hydraulic telescopic rod expands and contracts, the support plate slides on the support column to limit the support plate.

[0021] Furthermore, the filter box and the box plate are fixedly connected by bolts, and the moving plate and the cleaning plate are fixedly connected by bolts.

[0022] By adopting the above technical solution, unscrew the bolts on the box plate to open the filter box, and then remove the bolts on the cleaning plate and the moving plate, which is convenient for cleaning and replacing the cleaning brush and for cleaning the filter screen.

[0023] In summary, the present application includes at least one of the following beneficial effects:

The moving plate drives the cleaning plate and the cleaning brush to move, cleaning the particulate matters such as dust and debris on the filter screen. The cleaned particulate matters enter the collection box along with the movement of the cleaning brush, collecting the debris and dust. At the same time, the moving plate slides on the limiting column to limit the moving plate. The cleaning mechanism reduces the clogging of the filter screen, reduces the influence on the filtering efficiency and filtering effect of the filter screen, reduces the frequency of replacing and maintaining the filter screen, is conducive to improving the service life of the filter screen, and is conducive to the operation of the melting furnace.

[0025] 2.

[0033] The embodiment of this application discloses a metal melting furnace.

[0034] Refer to Figure 1 andFigure 3 , a metal melting furnace, comprising a machine body 1. One side of the machine body 1 is fixedly provided with a first motor 2.

A cleaning mechanism is arranged between the filter box 14 and the support plate 13.

[0035] When the metal melting furnace is in use, the staff opens the cover plate 5, and adds the metal ingots and some waste metals to be melted into the melting furnace body 3 through the discharge port 4. Before adding, the hydraulic telescopic rod 7 can be telescoped to drive the support plate 13 to move, so that the connecting plate 6 drives the cover plate 5 to move, facilitating the opening of the cover plate 5. After starting the melting furnace body 3 to melt the metal inside, oxygen is provided through the air inlet pipe 9 for ventilation. After melting is completed, the hydraulic telescopic rod 7 is telescoped to open the cover plate 5, and then the first motor 2 is started to make the melting furnace body 3 tilt, driving the molten metal solution to flow out from the discharge port 4 into a specified container. During melting, the motor 10 drives the fan blade 11 to generate suction to inhale the waste gas during melting. The waste gas is filtered by the filter screen 12 and then discharged through the fixed pipe 22. The cleaning mechanism reduces the blockage of the filter screen 12, reduces the influence on the filtering efficiency and filtering effect of the filter screen 12, reduces the number of times of replacing and maintaining the filter screen 12, facilitates improving the service life of the filter screen 12, and facilitates the operation of the melting furnace.

The limiting column 17 slidably penetrates the moving plate 18. The limiting column 17 is located at the end of the moving plate 18 away from the screw rod 16. A cleaning plate 26 is arranged on the side of the moving plate 18. A cleaning component is arranged between the cleaning plate 26 and the support plate 13. The cleaning component includes cleaning brushes 19 fixed on the cleaning plate 26 and distributed in an array. The cleaning brushes 19 are in contact with the filter screen 12. A collection box 20 is arranged at the lower end of the filter box 14. The collection box 20 extends out of the filter box 14 and penetrates the support plate 13. The collection box 20 corresponds to the filter screen 12. The filter box 14 and the collection box 20 are fixedly connected by bolts. One end of the filter screen 12 extends out of the filter box 14. The filter screen 12 and the filter box 14 are fixedly connected by bolts.

[0037] When the metal melting furnace is in use, start the second motor 15. The motor drives the screw rod 16 to rotate. The rotation of the screw rod 16 causes the moving plate 18 to move. The moving plate 18 drives the cleaning plate 26 and the cleaning brushes 19 to move, cleaning the dust, debris and other particulate matters on the filter screen 12. The cleaned particulate matters enter the collection box 20 along with the movement of the cleaning brushes 19, collecting the debris and dust. At the same time, the moving plate 18 slides on the limiting column 17 to limit the moving plate 18. When cleaning is required, loosen the bolts on the collection box 20 to release the restriction on the collection box 20, and then loosen the bolts on the filter screen 12 to pull out the filter screen 12, cleaning and replacing the collection box 20 and the filter screen 12. After completion, reset. By the cleaning mechanism, the situation of the filter screen 12 being blocked is reduced, the influence on the filtering efficiency and filtering effect of the filter screen 12 is reduced, the number of times of replacing and maintaining the filter screen 12 is reduced, the service life of the filter screen 12 is improved, and the operation of the melting furnace is facilitated.

[0038] Refer to Figure 2 and Figure 3 , a connecting pipe 23 is fixedly connected to the lower end of the fixed pipe 22. A circulating pipe 24 is fixedly connected to the lower end of the connecting pipe 23. The end of the circulating pipe 24 away from the connecting pipe 23 is fixedly connected to the melting furnace body 3. The connecting pipe 23 is a metal telescopic pipe. Two symmetric support columns 25 are fixed on the machine body 1. The support columns 25 penetrate the support plate 13. The support plate 13 is located on one side of the hydraulic telescopic rod 7. The filter box 14 and the box plate 21 are fixedly connected by bolts. The moving plate 18 and the cleaning plate 26 are fixedly connected by bolts.

[0039] When the metal melting furnace is in use, the heat filtered by the filter screen 12 enters the connecting pipe 23 through the fixed pipe 22, then enters the circulating pipe 24 through the connecting pipe 23, and enters the melting furnace body 3, reducing heat waste and facilitating the melting of the melting furnace body 3. Since the connecting pipe 23 is a metal telescopic pipe, it facilitates the movement of the cover plate 5. When the hydraulic telescopic rod 7 expands and contracts, the support plate 13 slides on the support column 25 to limit the support plate 13. When cleaning is required, loosen the bolts on the box plate 21, open the filter box 14, and then remove the bolts on the cleaning plate 26 and the moving plate 18, facilitating the cleaning and replacement of the cleaning brush 19 and the cleaning of the filter screen 12.

[0040] The implementation principle of a metal melting furnace in this embodiment is as follows: When the metal melting furnace is in use, the staff opens the cover plate 5, and adds the metal ingots and some waste metals to be melted into the melting furnace body 3 through the discharge port 4. Before adding, the hydraulic telescopic rod 7 can be expanded and contracted to drive the support plate 13 to move, so that the connecting plate 6 drives the cover plate 5 to move, facilitating the opening of the cover plate 5. After starting the melting furnace body 3, the metal inside is melted, and oxygen is provided through the intake pipe 9 for ventilation. After melting is completed, the hydraulic telescopic rod 7 expands and contracts, the cover plate 5 opens, and then the motor 1 is started, causing the melting furnace body 3 to tilt, driving the molten metal solution to flow out of the discharge port 4 into a specified container. During melting, the motor 10 drives the fan blade 11 to generate suction, inhaling the waste gas during melting, filtering it through the filter screen 12, and then discharging it through the fixed pipe 22;

[0041] When the metal melting furnace is in use, the motor 2 is started, and the motor drives the screw rod 16 to rotate. The rotation of the screw rod 16 causes the moving plate 18 to move. The moving plate 18 drives the cleaning plate 26 and the cleaning brush 19 to move, cleaning the dust, debris and other particles on the filter screen 12. The cleaned particles enter the collection box 20 as the cleaning brush 19 moves, collecting the debris and dust. At the same time, the moving plate 18 slides on the limiting column 17 to limit the moving plate 18;

[0042] When the metal melting furnace is in use, the heat filtered by the filter screen 12 enters the connecting pipe 23 through the fixed pipe 22, then enters the circulating pipe 24 through the connecting pipe 23, and enters the melting furnace body 3, reducing heat waste and facilitating the melting of the melting furnace body 3. Since the connecting pipe 23 is a metal telescopic pipe, it facilitates the movement of the cover plate 5. When the hydraulic telescopic rod 7 expands and contracts, the support plate 13 slides on the support column 25 to restrict the support plate 13. When cleaning is required, turn the bolts on the collection box 20 to release the restriction on the collection box 20, then turn the bolts on the filter screen 12 and pull out the filter screen 12 to clean and replace the collection box 20 and the filter screen 12. Turn the bolts on the collection box 20 to release the restriction on the collection box 20, then turn the bolts on the filter screen 12 and pull out the filter screen 12 to clean and replace the collection box 20 and the filter screen 12. After completion, reset. After completion, reset.
