Abstract
Description
Technical Field
[0001] This utility model relates to a protective slag feeding device, and in particular to a device that can assist workers in efficiently and safely feeding protective slag into the crystallizer, belonging to the technical field of crystallizer protective slag feeding equipment. Background Technology
[0002] In continuous casting production, the protective slag in the crystallizer has a significant impact on billet production, offering advantages such as lubrication, reduced oxidation, and uniform heat transfer. Currently, the addition of protective slag is done manually. Workers carry bags containing the slag to the slag inlet at the top of the crystallizer and add it in. During this process, the temperature inside the crystallizer is extremely high, posing a safety hazard as workers operate in a high-temperature environment. Furthermore, the weight of the slag added each time is fixed, and workers cannot precisely control the weight when manually pouring it. This can lead to either too much or too little slag being added. If too little slag is added, the protective slag in the crystallizer cannot perform its function effectively; if too much is added, production costs increase. Therefore, a feeding device is needed to assist workers in efficiently adding the required protective slag to the crystallizer. Utility Model Content

[0015] See Figure 1 This utility model includes a feeding section, a storage section, and a weighing section. There are multiple feeding sections, all of which are mounted on a casting platform. Each feeding section is connected to a different mold flux feeding hole. A mold may have multiple mold flux feeding holes, and the number of feeding sections is arranged according to the number of mold flux feeding holes, with each feeding section corresponding to one mold flux feeding hole. The storage section is mounted on the casting platform and is located to one side of the feeding section. The weighing section is mounted on the storage section. The weighing section feeds a specified amount of mold flux from the storage section into the feeding section.
[0016] The feeding section includes a first base 1, a lifting mechanism, a hopper 2, a first unloading valve, and a discharge pipe 3. The four corners of the bottom surface of the first base 1 are equipped with casters. These casters allow the first base 1 to move, thereby moving the discharge pipe 3 directly above the crystallizer protective slag feeding hole. The lifting mechanism is located on the top surface of the first base 1. The lifting mechanism can adjust the height of the end of the discharge pipe 3, thereby adjusting the distance between the end of the discharge pipe 3 and the protective slag feeding hole, ensuring that the protective slag discharged from the end of the discharge pipe 3 can smoothly enter the crystallizer protective slag feeding hole. The hopper 2 is mounted on the lifting mechanism. The first unloading valve is located at the discharge port at the bottom of the hopper 2. The top of the discharge pipe 3 is connected to the discharge end of the first unloading valve, and the bottom of the discharge pipe 3 is located directly above the crystallizer protective slag feeding hole. The first unloading valve controls the release of material from the hopper 2; opening the first unloading valve allows the protective slag in the hopper 2 to enter the crystallizer protective slag feeding hole through the discharge pipe 3.
[0017] The lifting mechanism includes two lifting components, which are symmetrically arranged on both sides of the top surface of the first base 1. Each lifting component includes a guide plate 4, a lifting plate 5, and a pin 6. The guide plate 4 is vertically arranged on one side of the top surface of the first base 1, and its top end is provided with a guide hole. The lifting plate 5 is inserted into the guide hole at the top end of the guide plate 4. The height of the hopper and the discharge pipe is controlled by the lifting of the lifting plate 5. The side wall of the lifting plate 5 is provided with multiple limiting holes along the vertical direction, and the side wall of the guide plate 4 is provided with positioning holes. The pin 6 passes through both the positioning hole on the guide plate 4 and the corresponding limiting hole on the lifting plate 5. The hopper 2 is arranged between the top side walls of the two lifting plates 5. Inserting the pin can fix the relative position between the guide plate 4 and the lifting plate 5, ensuring that the lifting plate 5 does not rise or fall arbitrarily after the height is adjusted.
[0018] The storage section includes a second base 7, columns 8, a top plate 9, a support column 10, and a storage mechanism. The four corners of the bottom surface of the second base 7 are each equipped with casters. These casters allow the storage section to move between the various hoppers 2, thus enabling feeding operations to different hoppers 2. The four corners of the top surface of the second base 7 are each equipped with columns 8, and the four corners of the bottom surface of the top plate 9 are connected to the tops of the four columns 8 respectively. The support column 10 is located at one end of the top surface of the top plate 9. The storage mechanism is mounted on the support column 10.
[0019] The weighing system includes a fixed inclined plate 11, weighing components, a weighing inclined plate 12, a side baffle 13, a display screen 14, and a material blocking plate 15. The top plate 9, away from the support column 10, is connected to the bottom end of the fixed inclined plate 11. The top of the side wall of the support column 10 is connected to the top of the fixed inclined plate 11 via a horizontal plate. There are four weighing components, each positioned at one of the four corners of the upper surface of the fixed inclined plate 11. The weighing components weigh the protective slag on the weighing inclined plate 12, and the weighing data is displayed on the display screen. The weighing inclined plate 12 is mounted on each weighing component. The side baffle 13... The side baffles 13 are arranged on both sides of the upper surface of the weighing inclined plate 12; the bottom ends of the end faces of the side baffles 13 that are close to each other are provided with limiting grooves, and the two ends of the material blocking plate 15 are respectively inserted into the limiting grooves of the two side baffles 13, with the bottom end of the material blocking plate 15 in contact with the top surface of the weighing inclined plate 12; the protective residue falling on the weighing inclined plate 12 can be retained and weighed by the material blocking plate 15. After the weighing is completed, the material blocking plate 15 can be removed so that the protective residue on the weighing inclined plate 12 can naturally slide into the hopper 2; the display screen 14 is arranged on the horizontal plate, and its signal input terminal is connected to the signal output terminal of the CPU.
[0020] The weighing device includes a guide cylinder, an insert rod, and a weighing device. The bottom end of the guide cylinder is located at one corner of the top surface of the fixed inclined plate 11, and the axis of the guide cylinder is a vertical line. The vertical axis of the guide cylinder ensures that when the insert rod is pressed against the weighing device, the data sensed by the weighing device is the actual weight of the protective slag. The weighing device is located at the bottom end of the inner wall of the guide cylinder, and the insert rod is inserted inside the guide cylinder, with the bottom end of the insert rod touching the weighing device. The weight of the protective slag on the weighing inclined plate 12 is pressed onto the weighing inclined plate 12. The weight of the protective slag is the data detected by the weighing device minus the known total weight of the insert rod, the weighing inclined plate 12, the side baffle 13, and the material blocking plate 15. The top end of the insert rod is connected to one corner of the bottom surface of the weighing inclined plate 12. The signal output terminal of the weighing device is connected to the signal input terminal of the CPU. The plane of the weighing inclined plate 12 is parallel to the plane of the fixed inclined plate 11.
[0021] The storage mechanism includes a storage bin 16; the storage bin 16 is mounted on the support column 10 by a bracket; a discharge valve is provided at the discharge port at the bottom of the storage bin 16, and the discharge valve at the bottom of the storage bin 16 is located directly above the weighing inclined plate 12; the discharge of the storage bin 16 is controlled by controlling the discharge valve at the bottom of the storage bin 16.
[0022] The CPU module in this invention is model 87C196KC.
[0023] Operating principle: In the initial state, each feeding part is located in front of its corresponding protective slag feeding hole, and the end of the discharge pipe 3 in each feeding part is directly above the protective slag feeding hole corresponding to its position.
[0024] When protective slag needs to be added to the crystallizer, move the second base 7 until the weighing ramp 12 is directly above the first hopper 2. Then open the discharge valve at the bottom of the storage bin 16 so that the protective slag inside falls onto the weighing ramp 12. The display screen 14 displays the weight of the falling protective slag in real time. After the data on the display screen reaches the preset protective slag addition weight, close the discharge valve of the storage bin 16. Then pull the baffle plate 15 upward to add the protective slag on the weighing ramp 12 into the hopper 2. After the protective slag is discharged, drive the baffle plate 15 to reset and drive the second base 7 to move so that the weighing ramp 12 moves above the next hopper 2. Repeat the above actions until all hoppers 2 are filled with the required weight of protective slag.
[0025] Finally, when protective slag needs to be added, the discharge valve at the bottom of hopper 2 is opened, and the protective slag in hopper 2 is sent into the crystallizer through discharge pipe 3, thereby realizing the precise weight of protective slag added to the crystallizer.
