Description

Technical Field

[0001] This invention relates to an incinerator, and more particularly to an easy-to-clean rare earth incinerator. Background Technology

[0002] Rare earth elements are known as "industrial vitamins" and have become an extremely important strategic resource. With the advancement of science and technology and the continuous breakthroughs in application technology, the value of rare earth oxides will become increasingly greater. However, rare earth elements in rare earth ores are usually mixed with other impurity elements, so it is necessary to separate the impurity elements by burning to improve the purity of rare earth elements and generate rare earth oxides.

[0003] A smelting furnace is a device that melts metal ingots and some scrap metals, adds necessary alloying components, and then melts them into the desired alloy through operations such as slag removal and refining. Therefore, it is also widely used in the preparation of rare earth minerals.

[0004] However, existing rare earth crucible smelting furnaces tend to have combustion products adhering to their walls after use. Therefore, after each use, the inner walls need to be manually scraped and cleaned to prevent affecting the normal operation of the smelting furnace. This process is time-consuming and labor-intensive, which greatly limits the efficiency of the incinerator in preparing and processing rare earth ores. Summary of the Invention

[0005] In order to overcome the shortcomings mentioned in the background art, the present invention provides an easy-to-clean rare earth incinerator, thereby solving the above problems.

[0006] The technical solution of the present invention is: an easy-to-clean rare earth incinerator, comprising a furnace tank, an integrated controller and a tank cover, wherein the integrated controller is fixedly installed on the furnace tank, the tank cover is rotatably installed on the furnace tank, and the furnace tank also includes an electric push rod, a lifting plate and a connecting rod. The electric push rods electrically connected to the integrated controller are symmetrically fixedly installed on the furnace tank. The furnace tank is provided with a lifting plate that is close to its inner side wall and can move along it. The lifting plate is symmetrically fixedly connected to the connecting rods, and the two connecting rods are respectively fixedly connected to the telescopic rods of the electric push rods on the same side.

[0007] Furthermore, the can lid has a sealing ring on the contact surface with the furnace can.

[0008] Furthermore, it also includes a scraping assembly, which includes a mounting plate, a fixing block, a connecting block, a moving frame, and a scraper. Mounting plates are symmetrically fixedly installed on the furnace tank. Fixing blocks are fixedly connected to the ends of the two mounting plates that are close to each other. Connecting blocks are rotatably connected to the ends of the two fixing blocks that are close to each other. A moving frame is slidably connected between the two connecting blocks. A scraper is fixedly connected to the moving frame.

[0009] Furthermore, it also includes torsion springs, with torsion springs provided at the connection points between the two connecting blocks and the corresponding fixed blocks.

[0010] Furthermore, it also includes a pulling assembly, which includes a stepper motor, a winding wheel, a pull rope, and a return spring. Stepper motors electrically connected to the integrated controller are fixedly installed on the side of the two mounting plates that are close to each other. Winding wheels are fixedly connected to the output shafts of the two stepper motors. Pull ropes are provided between the two winding wheels and the moving frame, and return springs are provided between the two connecting blocks and the moving frame.

[0011] Furthermore, it also includes a rotating assembly, which includes a guide rod, an electric carriage, and a control assembly. Guide rods are fixedly installed on the side of the two mounting plates that are close to each other. Electric carriages that are electrically connected to the integrated controller are slidably connected to the two guide rods. The other ends of the two electric carriages are fixedly connected to the connecting blocks on the same side. A control assembly for improving the electrical control accuracy of the integrated controller is provided on the left mounting plate.

[0012] Furthermore, the control component includes sensor I and sensor II. Sensor I, which is electrically connected to the integrated controller, is fixedly mounted on the left mounting plate. When the moving frame moves upward, the scraper will abut against sensor I. Sensor II, which is electrically connected to the integrated controller, is fixedly mounted on the left mounting plate. When the moving frame moves forward, the scraper will abut against sensor II.

[0013] Furthermore, the scraper has an inclined surface.

[0014] Furthermore, it also includes a collection component, which includes guide rails, a collection basket, pull rods, wedge blocks, and return springs. Guide rails are symmetrically fixedly installed on the furnace tank. A collection basket that fits into the furnace tank is slidably connected between the two guide rails. Pull rods are slidably connected to the two guide rails on opposite sides. Return springs are provided between the connection points of the two pull rods and the corresponding guide rails. Wedge blocks are fixedly connected to the ends of the two pull rods that are close to each other.

[0015] Furthermore, the two wedges are provided with downward-facing inclined surfaces on the sides where they are close to each other.

[0016] The beneficial effects are: 1. This invention sets up a sliding lifting plate inside the furnace tank and uses an electric push rod to drive the lifting plate to lift the incinerated rare earth upwards. During this process, the lifting plate will scrape the inner wall of the furnace tank, thereby preventing the incinerated rare earth from sticking to the inner wall of the furnace tank. This ensures the full collection of rare earth after processing, reduces processing losses, reduces the difficulty of cleaning for workers in the later stage, and improves the efficiency of rare earth preparation.

[0017] 2. This invention, by setting up a movable frame and scraper, and using a pull rope and an electric slide to control the movement and rotation of the movable frame, can automatically push the processed rare earth on the lifting plate, thereby improving the automation level of the device, reducing the workload of workers, and further improving the collection efficiency of rare earth.

[0018] 3. By setting sensors I and II on the mounting plate, the integrated controller can accurately control the start and stop of the electric slide when the moving frame drives the scraper to move. This enables the moving frame to flip backward synchronously when it moves, and the moving frame also flips when the lifting plate moves to the top of the furnace, thus ensuring the continuity of the pushing action.

[0033] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0034] Example 1: An easy-to-clean rare earth incinerator, such as Figures 1-4 As shown, the furnace includes a furnace tank 1, an integrated controller 101, and a tank cover 2. The integrated controller 101 is bolted to the lower front part of the furnace tank 1. The tank cover 2 is rotatably mounted on the top surface of the furnace tank 1. The tank cover 2 has a sealing ring on the contact surface with the furnace tank 1, which increases the sealing between the tank cover 2 and the furnace tank 1. The furnace also includes an electric push rod 3, a lifting plate 4, and a connecting rod 5. The electric push rod 3, which is electrically connected to the integrated controller 101, is symmetrically bolted to the outer side wall of the furnace tank 1. The lifting plate 4 is provided inside the furnace tank 1 and is close to its inner side wall and can move up and down along it. The connecting rod 5 is symmetrically welded to the top surface of the lifting plate 4. The upper ends of the two connecting rods 5 are respectively bolted to the telescopic rods of the electric push rod 3 on the same side. The telescopic rods of the electric push rod 3 will drive the lifting plate 4 to move inside the furnace tank 1 through the connecting rods 5.

[0035] When rare earth incineration is required, first open the canister lid 2 by rotating it upwards, then pour the rare earth to be incinerated into the furnace canister 1. At this time, the lifting plate 4 is located on the inner bottom of the furnace canister 1 to receive the rare earth to be incinerated. Then, close the canister lid 2 by rotating it downwards again. The sealing ring on the canister lid 2 will increase the sealing effect of the furnace canister 1, thereby preventing heat leakage and saving energy consumption. After the rare earth incineration is completed, repeat the above steps to open the canister lid 2, and then start the electric push rod 3 through the integrated controller 101. The telescopic levers of the two electric push rods 3... The plate will extend upwards, thereby driving the lifting plate 4 to move synchronously upwards from inside the furnace tank 1 via the two connecting rods 5. As the lifting plate 4 moves upwards, it will also scrape the inner wall of the furnace tank 1, thereby preventing the rare earth after combustion from sticking to the inner wall of the furnace tank 1. This ensures the full collection of rare earth after processing, reduces processing losses, and also reduces the difficulty of cleaning the inner wall of the furnace tank 1 for workers later, improving the processing efficiency of rare earth combustion. When the lifting plate 4 moves to the upper part of the furnace tank 1, the processed rare earth can be collected.

[0036] Example 2: Based on Example 1, such as Figure 1 , Figure 5 and Figure 6 As shown, it also includes a scraping assembly, which includes a mounting plate 601, a fixing block 602, a connecting block 603, a moving frame 604, and a scraper 606. The upper part of the furnace tank 1 is symmetrically mounted with mounting plates 601 by bolts. The two mounting plates 601 are respectively connected to the fixing blocks 602 by bolts at their close ends. The two fixing blocks 602 are respectively rotatably connected to the connecting blocks 603 at their close ends. The moving frame 604 is slidably connected between the two connecting blocks 603. The upper end of the moving frame 604 is connected to the scraper 606 by bolts. The left side of the top surface of the scraper 606 is provided with an inclined surface.

[0037] like Figure 7 As shown, it also includes a torsion spring 605. A torsion spring 605 is provided between the connection points of the two connecting blocks 603 and the corresponding fixing blocks 602. The torsion spring 605 will reset the auxiliary moving frame 604.

[0038] like Figure 1 , Figure 8 and Figure 9 As shown, it also includes a pulling assembly, which includes a stepper motor 701, a winding wheel 702, a pull rope 703, and a return spring 704. The top surfaces of the two mounting plates 601 are respectively bolted to the side of each other, and the stepper motor 701 is electrically connected to the integrated controller 101. The output shafts of the two stepper motors 701 are respectively connected to the winding wheel 702 through couplings. The two winding wheels 702 are respectively provided with pull ropes 703 between the moving frame 604 and the moving frame 604. The two connecting blocks 603 are respectively provided with return springs 704 between the moving frame 604 and the moving frame 604.

[0039] like Figure 1 , Figure 10 and Figure 11As shown, it also includes a rotating assembly, which includes a guide rod 801, an electric carriage 802, and a control assembly. Guide rods 801 are bolted to the sides of the top surfaces of the two mounting plates 601 that are close to each other. Electric carriages 802, electrically connected to the integrated controller 101, are slidably connected to the two guide rods 801. The other ends of the two electric carriages 802 are bolted to the connecting blocks 603 on the same side. The left mounting plate 601 is equipped with a control mechanism to improve the electrical control accuracy of the integrated controller 101. The control component includes sensor I 803 and sensor II 804. Sensor I 803, which is electrically connected to the integrated controller 101, is bolted to the right side of the top surface of the left mounting plate 601. When the moving frame 604 moves upward, the inclined surface on the scraper 606 will abut against sensor I 803. Sensor II 804, which is electrically connected to the integrated controller 101, is bolted to the middle of the bottom surface of the left mounting plate 601. When the moving frame 604 moves forward, the scraper 606 will abut against sensor II 804.

[0040] Initially, the winding wheel 702 is in the winding state of the pull rope 703, and the return spring 704 is in the compressed state. After the rare earth incineration is completed and the can lid 2 is opened, the integrated controller 101 will simultaneously start the two electric push rods 3 and the stepper motor 701. The two stepper motors 701 will drive the corresponding winding wheel 702 to gradually loosen the pull rope 703 through the output shaft. After the pull rope 703 is removed, the return spring 704 will reset and push the moving frame 604 to move upward between the two connecting blocks 603. This will cause the scraper 606 to move upward synchronously. When the inclined surface at the left end of the scraper 606 contacts the sensor I 803, the sensor I 803 will send an electrical signal to the integrated controller 101. The integrated controller 101 will then activate the two electric slides 802 to move backward along the corresponding guide rods 801, thereby causing the connecting block 603 to rotate counterclockwise along the corresponding fixed block 602. This will cause the moving frame 604 to flip backward synchronously as it moves upward, causing the torsion spring 605 to deform. When the lifting plate 4 moves the processed rare earth to the top surface of the furnace 1, The moving frame 604 will also complete a 90-degree rotation, so that the scraper 606 is located behind the lifting plate 4. At this time, the integrated controller 101 will cause the stepper motor 701 to drive the corresponding winding wheel 702 to wind up the pull rope 703, thereby pulling the moving frame 604 forward through the pull rope 703. The return spring 704 will be compressed again, and the moving frame 604 will drive the scraper 606 to push the processed rare earth on the lifting plate 4 forward, thereby improving the collection efficiency of rare earth. When the scraper 606 moves forward to contact the sensor II 804, This indicates that the scraper 606 has finished pushing the rare earth on the lifting plate 4. The sensor II 804 will send an electrical signal to the integrated controller 101, which will then start the two electric slides 802 to move forward along the corresponding guide rods 801, thereby driving the connecting block 603 to rotate clockwise along the corresponding fixed block 602, so that the moving frame 604 will flip forward. The torsion spring 605 will also reset to assist the moving frame 604 in flipping, so that the moving frame 604 will drive the scraper 606 back to the front of the furnace pot 1, thus completing the scraping work.

[0041] like Figure 1 , Figure 12 and Figure 13As shown, it also includes a collection assembly, which includes a guide rail 901, a collection basket 902, a pull rod 903, a wedge block 904, and a return spring 905. The front of the furnace tank 1 is symmetrically mounted with guide rails 901 by bolts. The collection basket 902, which is in contact with the furnace tank 1, is slidably connected between the two guide rails 901. The upper part of the two guide rails 901 on the side away from each other is slidably connected with a pull rod 903. A return spring 905 is provided between the connection point of the two pull rods 903 and the corresponding guide rail 901. The ends of the two pull rods 903 that are close to each other are respectively connected with wedge blocks 904 by bolts. The sides of the two wedge blocks 904 that are close to each other are respectively provided with downward inclined surfaces. When the collection basket 902 moves upward, it will push the two inclined surfaces, causing the two wedge blocks 904 to move in the direction away from each other.

[0042] When it is necessary to collect the rare earth elements after incineration, the collection basket 902 is first slidably inserted into the lower part of the two guide rails 901 and then lifted upwards along the two guide rails 901. As the collection basket 902 moves upwards, it will push the two wedge blocks 904 away from each other along their inclined surfaces, compressing the return springs 905. After the collection basket 902 passes through the two wedge blocks 904, the return springs 905 will return to their original position, pushing the two wedge blocks 904 closer together. The collection basket 902 is then positioned and supported, so that its top surface is flush with the top surface of the furnace tank 1. The rare earth elements pushed down by the scraper 606 can then be collected through the collection basket 902. Once the collection basket 902 is full, the two levers 903 are pulled to move them away from each other. The two levers 903 will cause the wedge block 904 to move synchronously, thereby releasing the restriction on the collection basket 902. Then, the collection basket 902 can be slid down along the two guide rails 901 and removed.
