Description
Technical Field
[0001] This utility model relates to the field of feeding equipment technology, specifically to a feeding device for a melting furnace. Background Technology
[0002] Alloy melting furnaces are a common type of equipment used in industry for processing raw materials. Their main function is to heat and maintain the temperature of raw materials. Different melting furnaces can be used to process raw materials depending on the production conditions, such as dry-bed continuous melting furnaces, gas furnaces, and reverberatory furnaces. The melting furnace is directly related to energy consumption and metallurgical quality.
[0003] A search revealed that CN211346320U discloses a charging device for a melting furnace, including a support frame and a hydraulic cylinder located at the bottom center of the support frame. The furnace body is located on one side of the support frame, and casters with brake devices are located on both sides of the bottom of the support frame. Limit rods are located on both sides of the bottom of the support frame, and a first slide rail is located on the inner wall of the limit rod. A support cross plate is located between the limit rods, and a second slide rail is located on the top of the support cross plate. The bottom of the support cross plate is connected to the output shaft of the hydraulic cylinder, and a feeding component is located on the top of the support cross plate.
[0004] The aforementioned utility model lifts the raw material box by opening the hydraulic cylinder, and then completes the feeding operation by opening the second cylinder and the first cylinder respectively, thereby effectively improving the working efficiency of the device. However, when discharging the raw material box, one end of the discharge box is lifted upward to tilt it for discharge. When the raw material box is tilted, the material's flow resistance decreases due to the acceleration caused by gravity, and the discharge speed is likely to exceed expectations. High-speed discharge can easily impact the feed inlet of the melting furnace, thereby shortening the service life of the melting furnace. At the same time, excessively fast discharge speed can also disrupt the thermal balance, leading to local overheating or incomplete melting inside the melting furnace, further reducing the working stability of the melting furnace.
[0005] Therefore, it is of great importance to design a furnace feeding device to solve the above-mentioned defects. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0025] Example: Please refer to Figures 1-5 This utility model provides a technical solution:
[0026] A melting furnace feeding device includes a movable base 1, a melting furnace body 2 in front of the movable base 1, a lifting frame 3 fixedly installed on the top of the movable base 1, a lifting plate 4 slidably connected inside the lifting frame 3, a feeding base 5 fixedly installed on the top of the lifting plate 4, a movable slide 6 slidably connected on the top of the feeding base 5, and a conveyor frame 7 fixedly installed on the top of the movable slide 6.
[0027] First, a conveyor belt 701 is installed on the inner side of the conveyor frame 7. A storage box 702 is fixedly installed on the top of the conveyor frame 7. A guide hopper 703 is fixedly connected to the front end of the storage box 702. A discharge gate 704 is rotatably connected to the connection between the guide hopper 703 and the storage box 702. A discharge mechanism 705 is fixedly installed on the left side of the storage box 702 at a position corresponding to the discharge gate 704. When feeding the melting furnace body 2, the raw material is first put into the inside of the storage box 702. Then, the moving base 1 is moved to the outside of the melting furnace body 2. Then, the lifting plate 4 is used to lift the storage box 702. At this time, the moving base 1 is moved to the outside of the melting furnace body 2. The moving slide 6 moves forward so that the bottom end of the guide hopper 703 connects with the feed inlet at the top of the melting furnace body 2. Then, the discharge mechanism 705 releases the fixing of the discharge gate 704 so that it can rotate flexibly. At this time, the conveyor belt 701 is started to evenly discharge the raw material inside the storage box 702 into the feed inlet of the melting furnace body 2. The discharge speed can be controlled by controlling the conveying speed of the conveyor belt 701. This can meet the discharge requirements while avoiding the impact of excessive discharge speed on the feed inlet and the disruption of thermal balance, thereby improving the service life and working stability of the melting furnace body 2.
[0028] Furthermore, both the front and rear ends of the bottom of the conveyor frame 7 are fixedly connected to the top of the movable slide table 6 via mounting feet 706. A protective cover 707 is fixedly installed at the rear end of the conveyor frame 7 and outside the conveyor belt 701. The conveyor frame 7 is fixedly installed on the top of the movable slide table 6 via mounting feet 706, and the rear end of the conveyor belt 701 is protected by the protective cover 707.
[0029] Then, the feeding mechanism 705 includes a mounting frame 708 fixedly installed on the left side of the storage box 702. The left end of the feeding gate 704 is rotatably connected to the mounting frame 708 via a rotating shaft 709. A fixing plate 710 is fixedly connected to the left end of the rotating shaft 709. A fixing ring 711 is fixedly installed on the outer side of the fixing plate 710. An electric telescopic rod 712 is hinged to the top of the mounting frame 708. A hook 713 is rotatably connected to the top of the mounting frame 708 and the right end of the electric telescopic rod 712. The output end of the electric telescopic rod 712 is hinged to the bottom end of the hook 713. When feeding material into the storage box 702, the electric telescopic rod 712 is activated to drive the hook 713 to rotate, causing it to disengage from the inside of the fixing ring 711, thereby releasing the fixing plate 710. Subsequently, the feeding gate 704 can be opened under the push of the raw material inside the storage box 702, thereby controlling automatic material discharge.
[0030] Furthermore, each of the four corners of the bottom of the mobile base 1 is equipped with a caster wheel 101. Support feet 102 are threadedly connected to the bottom of the mobile base 1 and to the outside of the multiple caster wheels 101. The mobile base 1 moves to the outside of the melting furnace body 2 via the caster wheels 101 at its bottom. When feeding the raw materials inside the storage box 702, the support feet 102 are rotated so that their bottom ends abut against the ground, thereby ensuring the fixation of the mobile base 1 and further ensuring the stability of the feeding.
[0031] The first lead screw module 301 is fixedly installed on the left side of the lifting frame 3. The left end of the lifting plate 4 is connected to the first lead screw module 301 through the first lead screw pair 302. The lifting frame 3 is provided with a lifting groove 303 at the position corresponding to the first lead screw pair 302. When feeding materials into the storage box 702, the first lead screw module 301 is activated and the lifting plate 4 is moved upward under the connection of the first lead screw pair 302, thereby raising the storage box 702.
[0032] Secondly, sliders 401 are fixedly connected to the front and rear ends of both sides of the lifting plate 4. Multiple sliders 401 are slidably connected to the inner side of the lifting frame 3 through the slide groove 402. When the lifting plate 4 moves, multiple sliders 401 slide inside the slide groove 402, thereby ensuring the stability of the movement of the lifting plate 4.
[0033] Finally, a second lead screw module 501 is fixedly installed on the top of the feeding base 5. The bottom of the movable slide 6 is connected to the second lead screw module 501 through the second lead screw pair. Sliding sleeves 601 are fixedly installed on both the left and right ends of the bottom of the movable slide 6. The sliding sleeves 601 are slidably connected to the left and right ends of the feeding base 5 through the guide rails 602. After the storage box 702 is raised, the second lead screw module 501 is started and, under the connection of the second lead screw pair, the movable slide 6 is moved forward so that the bottom end of the guide hopper 703 is connected to the feed port on the top of the melting furnace body 2, thereby realizing automated feeding and improving work efficiency.
[0034] In this embodiment, the specific implementation scenario is as follows: When feeding the melting furnace body 2, the raw material is first put into the inside of the storage box 702. Then, the movable base 1 is moved to the outside of the melting furnace body 2, and then the storage box 702 is raised using the lifting plate 4. At this time, the movable slide 6 is moved forward so that the bottom end of the guide hopper 703 is connected to the feed port at the top of the melting furnace body 2. Then, the discharge mechanism 705 is used to release the fixation of the discharge door 704 so that it can rotate flexibly. At this time, the conveyor belt 701 is started to evenly discharge the raw material inside the storage box 702 into the feed port of the melting furnace body 2. The discharge speed can be controlled by controlling the conveying speed of the conveyor belt 701, so as to meet the discharge requirements while avoiding the impact of excessive discharge speed on the feed port and breaking the thermal balance. The whole operation process is simple and convenient. This utility model improves the service life and working stability of the melting furnace body 2 through design.
