Description

Technical Field

[0001] This utility model belongs to the field of waste metal melting and casting technology, and in particular relates to a waste metal melting and casting device. Background Technology

[0002] A scrap metal melting and casting device is a specialized piece of equipment designed to melt scrap metal at high temperatures and then recast it into new shapes. This device plays a vital role in the field of metal recycling and reuse, not only helping to reduce resource waste but also effectively lowering production costs and reducing environmental pollution.

[0003] Existing scrap metal melting and casting equipment typically uses a furnace to melt the metal, and then pours the molten metal into a mold for recasting. However, during the pouring process, the molten metal is difficult to control and is prone to splashing, which not only affects the surrounding environment but also poses a certain risk of injury to nearby workers. Therefore, we propose a scrap metal melting and casting equipment. Utility Model Content

[0004] The purpose of this invention is to provide a waste metal melting and casting device. By setting a flow-limiting component, specifically, when the operator rotates the handle counterclockwise, the threaded rod moves upward, preventing the sealing cover from being pushed or squeezed. At this time, the molten metal can push the sealing cover open, thus discharging through the drain port. By controlling the movement distance of the threaded rod, the operator can adjust the opening angle of the sealing cover, thereby controlling the flow rate of the molten metal and avoiding excessive discharge at one time, which could cause overflow. This significantly reduces the impact on the surrounding environment, improves safety, and reduces the risk of injury to workers. It solves the problem in existing waste metal melting and casting devices where the molten metal is difficult to control during the pouring process into the mold, easily causing splashing, which not only affects the surrounding environment but also poses a risk of injury to nearby workers.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a waste metal melting and casting device, comprising a base, a furnace disposed inside the base, and rotating shafts fixedly connected to the left and right sides of the furnace, both of which are rotatably connected to the base. A cover plate is inserted into the top of the furnace and fixedly connected by bolts. A flow-limiting component is disposed on the top of the cover plate, and a drain port is provided inside the cover plate. The flow-limiting component includes a sealing cover, an arc-shaped guide block disposed on the front of the sealing cover, the bottom of which is fixedly connected to the top of the cover plate. A stop block is contacted on the left and right sides of the sealing cover, and the bottom of both stop blocks is fixedly connected to the top of the cover plate. Next, a fixing block is fixedly connected to the top of the stop on the right side. The fixing block has a threaded hole inside, and a threaded rod is threadedly connected inside the threaded hole. A throttle is fixedly connected to the top of the threaded rod. A connecting frame is fixedly connected to the top of the sealing cover. The front and back of the connecting frame are rotatably connected to the stop by pins. By controlling the movement distance of the threaded rod, the operator can adjust the opening angle of the sealing cover, thereby controlling the flow rate of the molten metal, avoiding excessive discharge at one time and causing overflow, greatly reducing the impact on the surrounding environment, improving safety, and reducing harm to the operator.

[0007] Furthermore, the bottom of the sealing cap contacts the top of the cover plate, the bottom of the threaded rod contacts the top of the sealing cap, and the tops of the two stops are fixedly connected to limit plates, which are inclined; during the drainage process, the limit plates are used to shield and reduce splashing.

[0008] Furthermore, a fixed seat is fixedly connected to the left side of the base, an electric push rod is fixedly connected to the back of the fixed seat, a rack is slidably connected to the top of the fixed seat, a gear is meshed with the top of the rack, and the right side of the gear is fixedly connected to the left side of the rotating shaft located on the left. When the electric push rod is activated, it drives the rack to move, which in turn drives the gear to rotate, thereby realizing the forward and backward rotation of the furnace.

[0009] Furthermore, the front of the furnace contacts a limiting frame, the bottom of the limiting frame is fixedly connected to the top of the base, a conveyor is provided in front of the furnace, and a mold is provided on the conveyor belt at the top of the conveyor; after the furnace is flipped and reset, the limiting frame plays a limiting role in the reset furnace, so that the reset furnace is in a vertical state.

[0010] Furthermore, a flow guiding assembly is provided above the conveyor. The flow guiding assembly includes a flow guiding plate, an extension flow guiding plate is slidably connected to the top of the flow guiding plate, connecting blocks are fixedly connected to the left and right sides of the flow guiding plate, and fixing blocks are fixedly connected to the left and right sides of the extension flow guiding plate. A sliding rod is fixedly connected to the front of the fixing block, and a spring is sleeved on the outside of the sliding rod. When the furnace is rotated, the extension flow guiding plate will push the fixing blocks under the elastic action of the spring, causing the extension flow guiding plate to move backward, so that the back of the extension flow guiding plate is always in contact with the furnace surface, which can extend the flow guiding distance.

[0011] Furthermore, the connecting block has a sliding hole inside, and the connecting block is slidably connected to the sliding rod through the sliding hole. The front of the spring is fixedly connected to the back of the connecting block, and the back of the spring is fixedly connected to the front of the second fixing block. The guide plate and the extended guide plate are both inclined. Two fixing plates are fixedly connected to the bottom of the guide plate, and the bottom of both fixing plates is fixedly connected to the top of the conveyor. When the extended guide plate moves, it will drive the sliding rod to slide on the connecting block, thereby improving the stability of the extended guide plate during movement and preventing the extended guide plate from deviating.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model incorporates a flow-limiting component. Specifically, when the operator rotates the handle counterclockwise, the threaded rod moves upward, preventing the sealing cap from being pushed or squeezed. At this point, the molten metal can push the sealing cap open, allowing it to drain through the outlet. By controlling the movement distance of the threaded rod, the operator can adjust the opening angle of the sealing cap, thereby controlling the flow rate of the molten metal. This prevents excessive discharge at once, which could cause overflow, significantly reducing the impact on the surrounding environment and improving safety while minimizing harm to the operator.

[0014] 2. This utility model, by setting a flow guiding component, specifically, when the furnace is turned over, the extended flow guiding plate will push the fixed block two under the action of the spring elasticity, causing the extended flow guiding plate to move backward, so that the back of the extended flow guiding plate is always in contact with the furnace surface, and the slide rod slides on the connecting block. This method can extend the flow guiding distance, thereby reducing the leakage of liquid and improving the flow guiding effect.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figure 1-5As shown, this utility model is a waste metal melting and casting device, including a base 1, a furnace 11 is arranged inside the base 1, and rotating shafts 111 are fixedly connected to the left and right sides of the furnace 11. Both rotating shafts 111 are rotatably connected to the base 1. A cover plate 12 is inserted into the top of the furnace 11 and fixedly connected by bolts. A flow limiting component 14 is arranged on the top of the cover plate 12. A drain port 121 is opened inside the cover plate 12. The flow limiting component 14 includes a sealing cover 141. An arc-shaped flow guide block 143 is arranged on the front of the sealing cover 141. The bottom of the arc-shaped flow guide block 143 is fixedly connected to the top of the cover plate 12. A stop block 144 is in contact with the left and right sides of the sealing cover 141. The bottom of both stop blocks 144 is fixedly connected to the top of the cover plate 12. A fixing block 145 is fixedly connected to the top of the right stop block 144. 5. An internal threaded hole is provided, and a threaded rod 146 is threadedly connected inside the threaded hole. A handle 147 is fixedly connected to the top of the threaded rod 146, and a connecting bracket 148 is fixedly connected to the top of the sealing cover 141. The front and back of the connecting bracket 148 are rotatably connected to the stop block 144 via pins. When the operator rotates the handle 147 counterclockwise, the threaded rod 146 moves upward, and the sealing cover 141 is not pushed or squeezed. At this time, the molten metal can push the sealing cover 141 to open, and then be discharged through the drain port 121. By controlling the movement distance of the threaded rod 146, the operator can adjust the opening angle of the sealing cover 141, thereby controlling the flow rate of the molten metal, avoiding excessive discharge at one time and causing overflow, greatly reducing the impact on the surrounding environment, improving safety, and reducing harm to the operator.

[0026] The bottom of the sealing cover 141 contacts the top of the cover plate 12, the bottom of the threaded rod 146 contacts the top of the sealing cover 141, and the tops of the two stops 144 are fixedly connected to the limiting plate 142, which is inclined.

[0027] A fixed seat 13 is fixedly connected to the left side of the base 1. An electric push rod 131 is fixedly connected to the back of the fixed seat 13. A rack 132 is slidably connected to the top of the fixed seat 13. A gear 133 is meshed with the top of the rack 132. The right side of the gear 133 is fixedly connected to the left side of the rotating shaft 111 located on the left.

[0028] The furnace 11 is in contact with the limit frame 15 on the front. The bottom of the limit frame 15 is fixedly connected to the top of the base 1. A conveyor 2 is provided in front of the furnace 11. A mold 21 is provided on the conveyor belt at the top of the conveyor 2.

[0029] A flow guiding assembly 3 is provided above the conveyor 2. The flow guiding assembly 3 includes a flow guiding plate 31, an extension flow guiding plate 32 is slidably connected to the top of the flow guiding plate 31, connecting blocks 36 are fixedly connected to the left and right sides of the flow guiding plate 31, and fixing blocks 34 are fixedly connected to the left and right sides of the extension flow guiding plate 32. A sliding rod 35 is fixedly connected to the front of the fixing block 34, and a spring 37 is sleeved on the outside of the sliding rod 35. When the furnace 11 is flipped, the extension flow guiding plate 32 will be pushed by the fixing blocks 34 under the elastic action of the spring 37, causing the extension flow guiding plate 32 to move backward, so that the back of the extension flow guiding plate 32 is always in contact with the surface of the furnace 11, and the sliding rod 35 slides on the connecting block 36. This method can extend the flow guiding distance, thereby reducing liquid leakage and improving the flow guiding effect.

[0030] The connecting block 36 has a sliding hole inside, and the connecting block 36 is slidably connected to the sliding rod 35 through the sliding hole. The front of the spring 37 is fixedly connected to the back of the connecting block 36, and the back of the spring 37 is fixedly connected to the front of the fixing block 34. The guide plate 31 and the extended guide plate 32 are both inclined. Two fixing plates 33 are fixedly connected to the bottom of the guide plate 31, and the bottom of the two fixing plates 33 are fixedly connected to the top of the conveyor 2.

[0031] One specific application of this embodiment is:

[0032] In use, remove the cover plate 12, then place the scrap metal into the furnace 11, and then install the cover plate 12 back onto the furnace 11, securing it with bolts. The metal in the furnace 11 can then be melted. During the melting process, place the mold 21 on the conveyor 2 and transport it to the bottom of the guide plate 31. Once the metal in the furnace 11 has melted, activate the electric push rod 131 to move the rack 132 backward. The rack 132 will then drive the gear 133 to rotate, and the gear 133 will drive the shaft 111 to rotate... When the furnace 11 is rotated, the liquid metal inside will not leak out because the drain port 121 on the cover plate 12 is sealed by the sealing cover 141. When the furnace 11 is rotated to a suitable angle, the electric push rod 131 stops. When the furnace 11 is rotated, the extended guide plate 32 will be pushed by the fixed block 34 under the elastic action of the spring 37, so that the back of the extended guide plate 32 is always in contact with the surface of the furnace 11. The slide rod 35 slides on the connecting block 36. This method can extend the guide distance.

[0033] After the furnace 11 is flipped, the operator turns the handle 147 counterclockwise to drive the threaded rod 146 upward. The sealing cover 141 is not pushed or squeezed. At this time, the molten metal will push the sealing cover 141 to open. The sealing cover 141 will then rotate on the stop block 144 through the connecting bracket 148, causing the sealing cover 141 to flip. Since the side of the sealing cover 141 is in contact with the stop block 144, the liquid will not overflow from the side. At this time, the molten metal will be discharged through the drain port 121 and guided by the arc-shaped guide block 143, flowing into the extension guide plate 32 and the guide plate 31, and then entering the mold 21. During the discharge process, the limiting plate 142 is used to shield and reduce splashing. At the same time, the operator can adjust the opening angle of the sealing cover 141 by controlling the movement distance of the threaded rod 146, thereby controlling the flow rate of the molten metal and avoiding excessive discharge at one time, which could cause overflow.

[0034] After the molten metal is discharged, the operator turns the handle 147 clockwise to move the threaded rod 146 downward and push the sealing cover 141 to fit tightly against the top of the cover plate 12, thereby sealing the drain port 121. Then, the electric push rod 131 is activated to move the rack 132 forward, turning the furnace 11 over and resetting it. The limit frame 15 then limits the resetting furnace 11, allowing other waste metals to be processed again.
