Description

Technical Field

[0001] The present application relates to the technical field of molten aluminum, and in particular to a molten aluminum insulation furnace. Background Art

[0002] In industrial processing, aluminum solid is usually converted into aluminum liquid through industrial processing before use. When aluminum liquid is difficult to use up at one time, it is usually stored in a holding furnace and kept warm for subsequent use.

[0003] A Chinese patent with publication number CN220250641U discloses a molten aluminum insulation furnace, including an insulation furnace and a heating wire installed on the insulation furnace. The heating wire continuously heats and insulates the molten aluminum inside the insulation furnace body, pours the molten aluminum into the insulation furnace through a pouring pipe, and stirs the molten aluminum through a hybrid mechanism, thereby accelerating the flow of the molten aluminum and delaying the condensation of the molten aluminum. The hybrid mechanism drives the secondary hybrid mechanism to work, increasing the stirring area of ​​the molten aluminum, thereby accelerating the flow of the molten aluminum and increasing the area contacting the electric heating wire.

[0004] In the related art, the molten aluminum inside the insulation furnace body is stirred by a hybrid mechanism and a secondary hybrid mechanism to reduce the condensation of the molten aluminum. Therefore, when the molten aluminum inside the furnace body is released and used, part of the molten aluminum is likely to adhere to the hybrid mechanism and the secondary hybrid mechanism, affecting the utilization rate of the molten aluminum. Utility Model Content

[0005] In order to reduce the adverse effects on the utilization rate of molten aluminum, the present application provides a molten aluminum insulation furnace.

[0006] The present application provides a molten aluminum holding furnace adopting the following technical solution:

[0007] A molten aluminum insulation furnace comprises a furnace body and an insulation layer arranged on the outside of the furnace body, an electric heating wire is wound in the side wall of the insulation layer, a plurality of electric heating rods are arranged along the height direction of the furnace body in the furnace body, the electric heating rods are fixed to the upper side of the insulation layer, the furnace body rotates around the electric heating rods, and a rotating component for driving the furnace body to rotate is provided on the insulation layer.

[0008] By adopting the above technical solution, molten aluminum is added to the furnace body. At this time, the electric heating wire on the insulation layer and the electric heating rod in the furnace body heat the molten steel in the furnace body at the same time. At this time, the insulation layer makes it difficult for the heat in the furnace body to dissipate from the side wall of the furnace body, and the rotating assembly drives the furnace body to rotate, so that the molten aluminum in the furnace body is driven and rotates with the furnace body, thereby facilitating the conduction of heat in the molten aluminum, reducing the possibility of some molten aluminum being difficult to heat and condensing, and reducing the adverse effect on the utilization rate of the molten aluminum.

[0009] Optionally, the rotating assembly includes a first bevel gear sleeved on the outside of the furnace body, a second bevel gear inserted into and rotatably connected to the insulation layer and meshing with the first bevel gear, and a first motor driving the second bevel gear to rotate is installed on the insulation layer.

[0010] By adopting the above technical solution, the first motor drives the second bevel gear to rotate and drives the furnace body to rotate through the first bevel gear, so that the molten aluminum in the furnace body rotates driven by the rotation of the furnace body side wall, thereby facilitating the conduction of heat in the molten aluminum, reducing the possibility of some molten aluminum being difficult to heat and condensing, and reducing the adverse effects on the utilization rate of the molten aluminum.

[0011] Optionally, a scraper plate parallel to the cross-sectional direction of the furnace body is slidably connected inside the furnace body, the electric heating rods pass through the scraper plate and are slidably connected to the scraper plate, a feed pipe is installed on the upper end of the insulation layer, a receiving hole corresponding to the feed pipe is opened on the scraper plate, and a sliding component for driving the scraper plate to move is provided on the upper end of the insulation layer and close to the electric heating rod.

[0012] By adopting the above technical scheme, when the molten aluminum insulated in the furnace body needs to be used, the molten aluminum is released. At this time, part of the molten aluminum adheres to the inner wall of the furnace body and the side wall of the electric heating rod. At this time, the sliding assembly drives the scraper plate to move toward the lower end of the insulation layer, thereby scraping the molten aluminum on the inner wall of the furnace body and the electric heating rod to the lower end of the insulation layer, thereby reducing the possibility of molten aluminum remaining in the furnace body and reducing the adverse effect on the utilization rate of the molten aluminum.

[0013] Optionally, the sliding assembly includes a screw rotatably connected to one side of the upper end of the insulation layer, the screw passes through the scraper plate and is threadedly connected to the scraper plate, and the upper end of the screw passes through the upper end of the insulation layer and is equipped with a second motor fixedly connected to the insulation layer.

[0014] By adopting the above technical solution, the second motor drives the lead screw to rotate. At this time, the scraper plate threadably connected to the lead screw moves along the length direction of the lead screw under the drive of the lead screw, thereby scraping the inner wall of the furnace body and the outer wall of the electric heating rod. The electric heating rod limits the scraper plate, reducing the possibility of the scraper plate rotating the lead screw, thereby further reducing the adverse effect on the utilization rate of molten aluminum.

[0015] Optionally, the scraper plate is provided with a sealing plate for sealing the receiving hole, and the scraper plate is provided with a receiving groove adapted to the receiving hole, one end of the sealing plate is inserted into the receiving groove and is slidably connected to the scraper plate, and the upper side of the other end of the sealing plate is set to be an inclined surface inclined downwardly away from the receiving groove, and the receiving groove is provided with a spring connecting the sealing plate and the scraper plate.

[0016] By adopting the above technical solution, when the scraper plate moves downward, the sealing plate blocks the receiving hole to reduce the possibility of molten aluminum passing through the receiving hole. When the scraper plate moves upward until the lower end of the feed pipe contacts the inclined surface on the sealing plate, the scraper plate continues to be driven upward. At this time, the lower end of the feed pipe squeezes the inclined surface on the upper side of the sealing plate and drives the sealing plate to move in the direction close to the receiving groove until it completely enters the receiving groove. At this time, the spring is compressed, which facilitates the feed pipe to feed into the furnace body.

[0017] Optionally, the lower end of the insulation layer is configured to be a cone with a diameter gradually decreasing toward the side away from the upper end of the insulation layer. The lower end of the inner side of the insulation layer is rotatably connected to a cleaning plate whose rotation axis coincides with the rotation axis of the furnace body. The lower side of the cleaning plate contacts the inclined surface of the lower side of the insulation layer. The insulation layer is provided with a driving member for driving the cleaning plate to rotate.

[0018] By adopting the above technical scheme, when the molten aluminum on the inner wall of the furnace body and the electric heating rod is completely scraped off, the driving member drives the cleaning plate to rotate, thereby driving the molten aluminum adhering to the inner wall of the lower end of the insulation layer to move and separate from the furnace body through the lower end of the insulation layer, thereby further reducing the possibility of molten aluminum adhering to the furnace body and being difficult to scrape off, and reducing the adverse effect on the utilization rate of molten aluminum.

[0019] Optionally, the driving member includes a first gear fixedly connected to the lower side of the cleaning plate, one side of the first gear is meshed with a second gear rotatably connected to the insulation layer, and a third motor is installed on the insulation layer to drive the second gear to rotate.

[0020] By adopting the above technical solution, the third motor drives the cleaning plate to rotate through the second gear and the first gear. At this time, the lower side of the cleaning plate scrapes the lower side of the inside of the insulation layer, reducing the possibility of aluminum liquid remaining on the insulation layer and reducing the adverse effect on the utilization rate of aluminum liquid.

[0021] Optionally, a temperature sensor is installed in the furnace body.

[0022] By adopting the above technical solution, the temperature sensor detects the temperature inside the furnace body, thereby facilitating the electric heating wire and the electric heating rod to heat the furnace body in time, reducing the possibility of condensation of molten aluminum due to insufficient temperature inside the furnace body, and further reducing the adverse effect on the utilization rate of molten aluminum.

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

[0024] 1. Add molten aluminum into the furnace body. At this time, the electric heating wire on the insulation layer and the electric heating rod in the furnace body heat the molten steel in the furnace body at the same time. At this time, the insulation layer makes it difficult for the heat in the furnace body to dissipate from the side wall of the furnace body, and the rotating assembly drives the furnace body to rotate, so that the molten aluminum in the furnace body is driven and rotates with the furnace body, so that the heat is easily conducted in the molten aluminum, reducing the possibility of some molten aluminum being difficult to heat and condensing, and reducing the adverse effect on the utilization rate of molten aluminum;

[0025] 2. When the aluminum liquid insulated in the furnace body needs to be used, the aluminum liquid is released. At this time, part of the aluminum liquid adheres to the inner wall of the furnace body and the side wall of the electric heating rod. At this time, the sliding component drives the scraper plate to move toward the lower end of the insulation layer, thereby scraping the aluminum liquid on the inner wall of the furnace body and the electric heating rod to the lower end of the insulation layer, thereby reducing the possibility of aluminum liquid remaining in the furnace body and reducing the adverse effect on the utilization rate of aluminum liquid;

[0026] 3. When the molten aluminum on the inner wall of the furnace body and the electric heating rod is completely scraped off, the driving member drives the cleaning plate to rotate, thereby driving the molten aluminum adhering to the inner wall of the lower end of the insulation layer to move and separate from the furnace body through the lower end of the insulation layer, thereby further reducing the possibility of molten aluminum adhering to the furnace body and being difficult to scrape off, and reducing the adverse effect on the utilization rate of molten aluminum.

DETAILED DESCRIPTION

[0031] The present application is further described in detail below in conjunction with the accompanying drawings.

[0032] The present application embodiment discloses a molten aluminum insulation furnace. Figure 1 and Figure 2A molten aluminum insulation furnace includes a vertical and cylindrical furnace body 1, both ends of the furnace body 1 are through. A cylindrical insulation layer 2 with a cavity inside is sleeved and rotatably connected to the outside of the furnace body 1, a support column 21 is installed at the lower end of the insulation layer 2, and a rotating component 3 for driving the furnace body 1 to rotate is arranged inside the insulation layer 2.

[0033] A feed pipe 22 is inserted and fixedly connected to the upper end of the insulation layer 2, and one end of the feed pipe 22 inserted into the insulation layer 2 is vertical and communicated with the inside of the furnace body 1. A vertical discharge pipe 23 is installed at the lower end of the insulation layer 2, and a control valve (not shown in the figure) is installed on the discharge pipe 23. A heating chamber 24 is opened on the side wall of the insulation layer 2, and an electric heating wire 4 is arranged in the heating chamber 24 and is wound along the height direction of the insulation layer 2.

[0034] Reference Figure 2 A plurality of vertical electric heating rods 41 are fixedly connected to the upper end of the inner part of the thermal insulation layer 2. In the embodiment of the present application, six electric heating rods 41 are arranged and evenly distributed along the circumference of the rotation axis of the furnace body 1. The electric heating wire 4 and the electric heating rod 41 are both electrically connected to a power source (not shown in the figure). A temperature sensor (not shown in the figure) is installed inside the furnace body 1. The temperature sensor is wirelessly connected to a control host (not shown in the figure), and the power source is wirelessly connected to the control host.

[0035] Molten aluminum is added into the furnace body 1 through the feed pipe 22. At this time, the power source drives the electric heating wire 4 on the insulation layer 2 and the electric heating rod 41 in the furnace body 1 to heat the molten steel in the furnace body 1 at the same time. The insulation layer 2 makes it difficult for the heat in the furnace body 1 to dissipate from the side wall of the furnace body 1, and the rotating component 3 drives the furnace body 1 to rotate and makes the molten aluminum in the furnace body 1 driven and rotate with the furnace body 1, so as to facilitate driving the heat to be conducted in the molten aluminum. The temperature sensor detects the internal temperature of the furnace body 1. When the internal temperature of the furnace body 1 is insufficient, the temperature sensor transmits an electrical signal to the control host. The control host controls the power source to drive the electric heating wire 4 and the electric heating rod 41 to timely heat up the furnace body 1, so as to facilitate the insulation of the molten aluminum.

[0036] Reference Figure 1 and Figure 2 The rotating assembly 3 includes a horizontal first bevel gear 31 which is sleeved on the outer wall of the furnace body 1 and fixedly connected to the outer wall of the furnace body 1. A vertical second bevel gear 32 is meshed on the upper side of one side of the first bevel gear 31. The upper side of the second bevel gear 32 passes through the upper end of the insulation layer 2 and is rotatably connected to the insulation layer 2. The outer side of the upper end of the insulation layer 2 is fixedly connected to a first motor 33 installed at the axis of the second bevel gear 32.

[0037] The first motor 33 drives the second bevel gear 32 to rotate and drives the furnace body 1 to rotate through the first bevel gear 31, so that the molten aluminum in the furnace body 1 rotates under the drive of the rotation of the side wall of the furnace body 1, which facilitates the conduction of heat in the molten aluminum and reduces the possibility that some molten aluminum is difficult to heat and condenses.

[0038] Reference Figure 2 A horizontal scraper plate 5 with side walls in contact with the inner side walls of the furnace body 1 is slidably connected inside the furnace body 1. The electric heating plates all pass through the scraper plate 5 and are slidably connected with the scraper plate 5. The scraper plate 5 is provided with receiving holes 51 adapted to the feed pipe 22. When the scraper plate 5 is located at the upper end inside the insulation layer 2, one end of the feed pipe 22 located in the insulation layer 2 passes through the receiving hole 51. The insulation layer 2 is provided with a sliding component 6 for driving the scraper plate 5 to move in the vertical direction.

[0039] Reference Figure 2 and Figure 3 The scraper plate 5 is provided with two horizontal and symmetrically arranged blocking plates 52 on both sides of the receiving hole 51. The scraper plate 5 is provided with two symmetrically arranged receiving grooves 53 on both sides of the receiving hole 51 and connected with the receiving hole 51. The ends of the blocking plates 52 that are far from each other are inserted into the receiving grooves 53 and are slidably connected with the scraper plate 5. The receiving grooves 53 are provided with springs 54 with one end fixedly connected with the scraper plate 5. The ends of the springs 54 that are close to each other are fixedly connected with the blocking plates 52 at the ends. The upper sides of the ends of the blocking plates 52 that are close to each other are provided with inclined surfaces that are inclined downward in the direction of approaching each other.

[0040] Reference Figure 1 and Figure 2 The sliding assembly 6 includes a screw 61 whose upper end passes through the insulation layer 2 and is rotatably connected to the side wall of the insulation layer 2. The screw 61 is vertically arranged, and the screw 61 passes through the scraper plate 5 and is threadedly connected to the scraper plate 5. A second motor 62 installed on the upper end of the screw 61 is fixedly connected to the outer wall of the upper end of the insulation layer 2.

[0041] When the molten aluminum insulated in the furnace body 1 needs to be used, the driving control valve releases the molten aluminum from the discharge pipe 23. At this time, part of the molten aluminum adheres to the inner wall of the furnace body 1 and the side wall of the electric heating rod 41. The second motor 62 drives the lead screw 61 to rotate. At this time, the scraper plate 5 threadedly connected to the lead screw 61 moves along the length direction of the lead screw 61 under the drive of the lead screw 61, thereby scraping the inner wall of the furnace body 1 and the outer wall of the electric heating rod 41, and the electric heating rod 41 limits the scraper plate 5, thereby scraping the molten aluminum on the inner wall of the furnace body 1 and the electric heating rod 41 to the lower end of the insulation layer 2.

[0042] When the scraper plate 5 moves downward, the sealing plate 52 blocks the receiving hole 51 to reduce the possibility of molten aluminum passing through the receiving hole 51. When the scraper plate 5 moves upward until the lower end of the feed pipe 22 contacts the inclined surface on the sealing plate 52, the scraper plate 5 continues to be driven to move upward. At this time, the lower end of the feed pipe 22 squeezes the inclined surface on the upper side of the sealing plate 52 and drives the sealing plate 52 to move toward the receiving groove 53 until it completely enters the receiving groove 53. At this time, the spring 54 is compressed, which facilitates the feed pipe 22 to feed into the furnace body 1.

[0043] Reference Figure 2 The lower end of the interior of the insulation layer 2 is set to be a cone whose diameter gradually decreases toward the side away from the scraper plate 5, and the upper end of the discharge pipe 23 passes through the insulation layer 2 and is rotatably connected to the insulation layer 2. A vertical cleaning plate 7 is provided on the lower side of the interior of the insulation layer 2, and the lower side of the cleaning plate 7 contacts the inclined surface of the lower side of the interior of the insulation layer 2. The rotation axis of the cleaning plate 7 coincides with the rotation axis of the furnace body 1, and a driving member 71 for driving the cleaning plate 7 to rotate is provided on the insulation layer 2.

[0044] Reference Figure 1 and Figure 2 The driving member 71 includes a vertical driving rod 711 fixedly connected to one end of the cleaning plate 7 close to the rotation axis of the furnace body 1, and a horizontal connecting rod 712 is fixedly connected to the lower end of the driving rod 711, and both ends are fixedly connected to the inner wall of the discharge pipe 23. A first gear 713 is sleeved and fixedly connected to the outer side of the discharge pipe 23, and a second gear 714 rotatably connected to the outer side wall of the insulation layer 2 is meshed on one side of the first gear 713, and a third motor 715 installed at the axis of the second gear 714 is fixedly connected to the insulation layer 2.

[0045] When the molten aluminum on the inner wall of the furnace body 1 and the electric heating rod 41 is completely scraped off, the third motor 715 drives the first gear 713 through the second gear 714 to drive the discharge pipe 23 to rotate. At this time, the connecting rod 712, the driving rod 711 and the cleaning plate 7 fixedly connected to the discharge pipe 23 rotate with the discharge pipe 23. At this time, the lower side of the cleaning plate 7 scrapes the lower side of the inside of the insulation layer 2, reducing the possibility of molten aluminum remaining on the insulation layer 2.

[0046] The implementation principle of the aluminum liquid insulation furnace in the embodiment of the present application is as follows: the second motor 62 drives the lead screw 61 to rotate, and at this time the scraper plate 5 moves along the length direction of the lead screw 61 and scrapes the inner wall of the furnace body 1 and the outer wall of the electric heating rod 41, thereby scraping the aluminum liquid on the inner wall of the furnace body 1 and the electric heating rod 41 to the lower end of the insulation layer 2, and the third motor 715 drives the first gear 713 through the second gear 714 to drive the discharge pipe 23 to rotate. At this time, the connecting rod 712, the driving rod 711 and the cleaning plate 7 fixedly connected to the discharge pipe 23 rotate with the discharge pipe 23, and the lower side of the cleaning plate 7 scrapes the lower side of the inside of the insulation layer 2, thereby reducing the possibility of aluminum liquid remaining on the insulation layer 2.
