Description

Technical Field

[0001] This utility model relates to the field of material feeding technology, specifically a material feeding device for magnesia-carbon brick forming and processing. Background Technology

[0002] Magnesia-carbon bricks are non-burning carbon composite refractory materials made from high-melting-point alkaline oxide magnesium oxide and high-melting-point carbon materials that are difficult to be wetted by slag, with the addition of various non-oxide additives and bonded with carbonaceous binders. Magnesia-carbon bricks are mainly used in the lining of converters, AC electric arc furnaces, and DC electric arc furnaces, as well as in the slag line of steel ladles. As a composite refractory material, magnesia-carbon bricks effectively utilize the strong slag erosion resistance of magnesia and the high thermal conductivity and low expansion of carbon, compensating for the biggest drawback of poor spalling resistance of magnesia. Its main characteristics include: good high-temperature resistance, strong slag resistance, good thermal shock resistance, and low high-temperature creep. Magnesia-carbon bricks produced with asphalt binders have high high-temperature plasticity due to the formation of anisotropic graphitized coke structures during the asphalt carbonization process.

[0003] The applicant found through a search that a Chinese patent discloses "A feeding device for molding and processing magnesia-carbon bricks", with publication number "CN216505866U". This patent mainly includes a discharge pipe, a connecting block fixedly connected to the surface of the discharge pipe, a limiting mechanism on one side of the discharge pipe, a side plate, limiting blocks fixedly connected to both ends of the side plate, a limiting rod fixedly connected between the limiting blocks, one end of the connecting block movably connected to the surface of the limiting rod, a sleeve block sleeved to one end of the discharge pipe, and a feeding device on the top of the sleeve block. This utility model, through the setting of the discharge pipe, auxiliary discharge device and feeding device, enables the device to achieve non-contact feeding into the mold, and the raw material flows in the pipe. After the discharge is completed, there is no obvious overflow point, which can reduce a lot of dust and protect the health of workers. At the same time, the setting of the brush can clean the dust on the mold after the feeding is completed, reducing the interference of dust on the mold.

[0004] However, the following shortcomings still exist:

[0005] During feeding, uneven feeding is easily caused by the inability to control the material output. When the output is too large, excess material is added to subsequent processes, exceeding actual needs and resulting in material waste. Material accumulation also affects the normal operation of the equipment. Conversely, if the output is too small, the material flow rate is too slow, making it difficult to form a continuous and smooth flow in the conveying line, which can easily lead to jamming. To address this, we propose a feeding device for magnesia-carbon brick molding and processing. Utility Model Content

[0006] The purpose of this utility model is to provide a feeding device for the molding and processing of magnesium carbon bricks.

[0022] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0023] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] Please see the appendix Figure 1 -Appendix Figure 4 This utility model discloses a feeding device for molding and processing magnesia-carbon bricks, including a hopper 1, with an adjusting component 2 installed below the hopper 1. The device is designed to handle various applications. Figure 4 As shown, the adjustment component 2 includes a mounting plate 201, a scraper 202, a baffle plate 203, a retaining post 204, a mounting plate 205, a groove 206, a scraper 207, and a handle 208. The mounting plate 201 is fixed to the bottom surface of the hopper 1. The scraper 202 is installed on the inner bottom surface of the mounting plate 201. The baffle plate 203 is evenly distributed between the mounting plate 201 and the mounting plate 205. The baffle plate 203 is blade-shaped and has a collar on its outside. The retaining post 208... 4. Fixed to the bottom surface of the baffle plate 203, the second mounting plate 205 is fixed below the baffle plate 203. Both the second mounting plate 205 and the first mounting plate 201 are circular. A groove 206 is formed on the top surface of the second mounting plate 205, and the groove 206 corresponds to the position of the locking post 204. The second scraper 207 is installed on the inner top surface of the second mounting plate 205. The second scraper 207 and the first scraper 202 correspond to the position of the baffle plate 203. The handle 208 is installed on one side of the collar. During material conveying, the operator can... Pulling handle 208 causes the collar to rotate, which in turn rotates the baffle plate 203. At this time, the locking pin 204 slides within the groove 206 as the baffle plate 203 rotates. During this sliding process, the degree of expansion and contraction of the baffle plate 203 is adjusted, thereby adjusting the size of the opening between the baffle plates 203. When the gap between the baffle plates 203 increases, the material outflow channel widens, the material outflow speed increases, and the flow rate increases accordingly. Conversely, when the gap narrows, the material outflow channel narrows, and the material outflow speed decreases. As the flow rate decreases, the material flow rate and falling speed can be adjusted according to demand. At the same time, during the rotation of the baffle plate 203, it will come into contact with scraper 1 202 and scraper 207. At this time, scraper 1 202 can effectively scrape off the material attached to the top surface of the baffle plate 203, while scraper 207 cleans the material remaining on the bottom surface of the baffle plate 203, preventing material residue and accumulation on the baffle plate 203, ensuring the surface of the baffle plate 203 is clean, and ensuring the accuracy and stability of material flow rate adjustment.

[0025] In Example 1, the hopper 1 is installed above the feed hopper 3. A sealing cover 4 is installed above the feed hopper 3. Pins 5 are provided on both sides of the sealing cover 4. A positioning pin 6 is provided on the bottom surface of the pins 5. Fixing plates 7 are fixed on both sides of the feed hopper 3. A slot 8 is provided on the top surface of the fixing plate 7. The slot 8 and the pins 5 are positioned correspondingly. A pin groove corresponding to the positioning pin 6 is provided inside the slot 8.

[0026] Specifically, when the sealing cover 4 closes the feed hopper 3, the pin 5 and the positioning pin 6 are inserted into the corresponding slots 8 and pin grooves. The insertion of the pin 5 and the positioning pin 6 can firmly fix the sealing cover 4, enhance the tightness of the sealing cover 4 when it is closed, and effectively prevent material leakage when the material in the hopper 1 is stirred.

[0027] In embodiment 2, a vibrator 9 is provided on one side of the feed hopper 3. The vibrator 9 is connected to the feed hopper 3 through a sleeve plate 10 on one side. The sleeve plate 10 is fitted on the outside of the feed hopper 3. A limit plate 11 is fixed below the feed hopper 3.

[0028] Specifically, when the vibrator 9 is working, it will generate vibration, which will be transmitted to the feed hopper 3 through the sleeve plate 10. The material accumulated, bridging or adhering to the hopper wall in the feed hopper 3 will fall instantly due to the impact force brought by the vibration, effectively preventing the material from clumping, ensuring smooth material flow and maintaining a stable supply of material.

[0029] In embodiment 3, the hopper 1 is equipped with a stirring assembly 12. The stirring assembly 12 includes a motor 1201, a stirring shaft 1202 and stirring blades 1203. The motor 1201 is located on one side of the hopper 1. The stirring shaft 1202 is connected to the drive end of the motor 1201. The stirring blades 1203 are symmetrically installed on both sides of the stirring shaft 1202.

[0030] Specifically, materials are stored in silo 1. During the storage process, to prevent clumping and uneven distribution of materials, motor 1201 drives the stirring shaft 1202 to rotate. The rotation of the stirring shaft 1202 drives the stirring blades 1203 to rotate. At this time, the rotation of the stirring blades 1203 stirs and mixes the materials in silo 1, effectively avoiding uneven distribution of material components, thereby ensuring that the final magnesia-carbon bricks have stable quality and consistent performance.

[0031] Working principle:

[0032] First, when feeding, the sealing cover 4 above the feed hopper 3 is opened, allowing the pin 5 and positioning pin 6 to disengage from the slot 8 and pin groove. At this time, the material is added into the feed hopper 3. When the material flow in the feed hopper 3 is obstructed, the vibrator 9 starts to work and generates vibration, which is transmitted to the feed hopper 3 through the sleeve plate 10. This causes the material that is piled up, bridging, or sticking to the wall in the feed hopper 3 to fall instantly under the impact force, preventing clumping and ensuring smooth material flow and stable supply.

[0033] Subsequently, the material enters the silo 1 through the feed hopper 3 for storage. During storage, in order to prevent the material from clumping and uneven distribution, the motor 1201 drives the stirring shaft 1202 to rotate, which in turn drives the stirring blades 1203 to rotate, stirring and mixing the material to ensure stable molding quality and consistent performance of the magnesia-carbon bricks.

[0034] During material feeding, the operator pulls handle 208 to drive the collar, causing the baffle plate 203 to rotate. The locking post 204 slides in the groove 206, adjusting the opening and closing of the baffle plate 203 to change the opening size and control the material flow rate and flow. At the same time, the rotation of the baffle plate 203 will contact scraper 1 202 and scraper 2 207, scraping off the material on their top and bottom surfaces respectively to prevent residue and ensure that the baffle plate 203 is clean.

[0035] The material enters the feeding box 13 through the adjusting component 2. At this time, the motor 2 14 drives the spiral shaft 15 and the spiral blade 16 to rotate. The rotation of the spiral blade 16 pushes the material to move towards the conveying pipe 17, ensuring that the material can be effectively conveyed into the conveying pipe 17, ensuring the continuity of the feeding process, and improving production efficiency. At this point, the entire workflow ends.
