Description

Technical Field

[0001] This application relates to the field of raw material conveying technology, and in particular to a raw material conveying device. Background Technology

[0002] In the field of material handling machinery and equipment, especially in metallurgy, ferroalloys, chemical, and building materials production, the conveying of granular and lumpy raw materials is crucial. With continuous industrial development, the requirements for refined, continuous, and green production are increasing. As a core process at the front end of the production line, raw material conveying directly affects the continuity and stability of subsequent smelting and processing steps. A good raw material conveying system can improve production efficiency, ensure product quality, and has a profound impact on the entire industrial production process. It relates to multiple aspects such as production costs, production safety, and environmental impact, and has therefore always been a focus of attention and research within the industry.

[0003] Currently, in the metallurgical and industrial raw material production and processing, two main methods are used for conveying traditional raw materials. One is the ordinary belt conveyor, which uses the rotation of the belt to transport materials. This method is characterized by its simple structure and low cost. The other is the fixed screw feeder, which uses the rotation of the screw to propel the material forward, achieving a certain degree of quantitative material conveying. However, these traditional conveying devices also have significant limitations. In actual production, both ordinary belt conveyors and fixed screw feeders face various problems and struggle to meet the stringent requirements of modern industry. The feeding speed of ordinary belt conveyors is relatively fixed, making it impossible to flexibly adjust according to the actual operating conditions of the downstream smelting equipment, often resulting in overfeeding or underfeeding. Furthermore, when conveying mixed lumpy or granular raw materials, jamming, accumulation, and deviation are prone to occur, affecting the uniformity of material conveying. Fixed screw feeders also suffer from the above problems and are inconvenient to clean and maintain.

[0004] Existing traditional raw material conveying devices have significant drawbacks. Firstly, their speed regulation capability is poor, failing to dynamically adjust the feed rate based on the operating conditions of downstream smelting equipment, leading to unbalanced feeding and affecting smelting temperature and production cycle. Secondly, their anti-clogging capability is weak; lumpy and granular raw materials are prone to jamming, accumulation, and deviation, resulting in poor material conveying uniformity. Furthermore, most of these devices employ open conveying structures, leading to severe dust overflow, causing not only raw material loss but also pollution of the workshop environment. Moreover, traditional equipment lacks effective anti-deviation structures and auxiliary structures for material screening, equalization, and anti-caking, resulting in high equipment failure rates, uneven furnace reactions, and product quality fluctuations, making it difficult to meet the current demands for refined, continuous, and green industrial raw material conveying production.

[0005] Therefore, in view of the above situation, there is an urgent need to develop a raw material conveying device to overcome the shortcomings in current practical applications. Summary of the Invention

[0016] Beneficial effects: It enables automatic belt deviation correction. The main frame serves as the supporting structure for the entire device, while the sealed dustproof conveyor shell prevents dust spillage, avoiding raw material loss and workshop dust pollution. The adjustable speed conveying mechanism allows for dynamic speed adjustment of feeding, meeting the feeding volume requirements of downstream smelting equipment under different operating conditions. Furthermore, in the adaptive deviation correction mechanism, the telescopic component drives the hinged frame to rotate around the fixed base, causing the bottom and side conveyor rollers to apply forces in different directions to the bottom of the conveyor belt, thereby correcting belt deviation and preventing structural loosening and abnormal noise malfunctions caused by belt deviation, thus improving the stability of equipment operation.

[0020] Beneficial effects: It enables pretreatment of raw materials, and the crushing roller can break up agglomerated raw materials, preventing agglomeration from entering downstream equipment and causing uneven reaction and product quality fluctuations in the furnace.

Furthermore, the multiple components of this mechanism work together to ensure stable and continuous crushing action, and the protective cover also protects the transmission components.

[0021] In one optional embodiment, four fixing blocks are fixedly arranged on the inner wall of the material conveying frame. The four fixing blocks are located below the crushing roller.

[0022] Beneficial effects: The crushing roller can crush the raw materials and prevent large pieces of raw materials from clogging the material; the screen plate, together with long springs, short springs and eccentric blocks, achieves vibratory screening under the drive of the four drive components, which can separate qualified raw materials from impurities, improve the purity and uniformity of raw material transportation, and reduce the risk of clogging caused by impurities; the slag discharge port can discharge the screened impurities in a timely manner, further avoiding clogging, ensuring the smoothness and stability of raw material transportation, and also helping to improve the quality of subsequent products.

[0029] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0030] The present invention provides the following embodiments: Example 1

[0031] This application discloses a raw material conveying device, referring to... Figure 1 , Figure 2 The system includes a frame body 1, a sealed dustproof conveying shell mechanism 2, an adjustable speed conveying mechanism 3, an anti-clogging and material equalization pretreatment mechanism 5, and an adaptive correction mechanism 4. The sealed dustproof conveying shell mechanism 2, mounted on the frame body 1, provides a supportive and dustproof environment for the conveying process. The adjustable speed conveying mechanism 3 and the adaptive correction mechanism 4 are housed within the sealed dustproof conveying shell mechanism 2. The adjustable speed conveying mechanism 3 adjusts the feeding speed according to the operating conditions of the downstream equipment, while the adaptive correction mechanism 4 prevents the conveyor belt 35 from deviating, ensuring the stability and accuracy of the conveying process. The anti-clogging and material equalization pretreatment mechanism 5, mounted on the sealed dustproof conveying shell mechanism 2, pre-treats the raw materials to prevent clogging and ensure uniform material distribution. This configuration gives the entire conveying device multiple functions, including anti-clogging, dustproof, and dynamic speed adjustment, meeting the needs of refined, continuous, and green industrial raw material conveying production.

[0032] Specifically, refer to Figure 4The sealed dustproof conveying shell mechanism 2 includes a sealed chamber 21, which is typically made of high-strength metal materials, such as stainless steel. This material is sturdy and durable, with good sealing properties and corrosion resistance. The sealed chamber 21 is fixedly mounted on the frame body 1. To ensure stability, it can be connected by welding or bolts. A feed inlet 211 is located at the top of the sealed chamber 21. The feed inlet 211 is generally square to facilitate the pouring of raw materials. A discharge outlet 212 is located on the side of the sealed chamber 21 away from the feed inlet 211. The discharge outlet 212 can also be square or round. Raw materials enter through the feed inlet 211 and are discharged through the discharge outlet 212 after being conveyed. Inclined surfaces 22 are located on the lower sides of the sealed chamber 21. The inclined surfaces 22 can be formed by bending steel plates. The two inclined surfaces 22 are fixedly connected to the frame body 1, also by welding or bolts. A first drive shaft 23 and a first driven shaft 24 are rotatably mounted between the side wall of the sealed chamber 21 and the inclined surface 22, respectively. The first drive shaft 23 and the first driven shaft 24 are typically made of high-strength alloy steel to ensure they do not easily deform during long-term operation. A slag-feeding belt 25 is driven between the first drive shaft 23 and the first driven shaft 24. The slag-feeding belt 25 can be a rubber ring belt with a certain degree of flexibility and wear resistance. A drive component 26 is mounted on the outside of the sealed chamber 21. The drive component 26 can be a motor, and the output shaft of the motor is connected to the first drive shaft 23 via a coupling. When the motor starts, it drives the first drive shaft 23 to rotate, thereby driving the slag-feeding belt 25 to circulate and transport small pieces of waste residue.

[0033] The above components, when combined, form a sealed conveying space, effectively preventing dust spillage and reducing raw material loss and environmental pollution. The drive component 26 drives the first drive shaft 23 to rotate, thereby causing the slag conveying belt 25 to operate, which can transport out any residual or fallen waste residue, ensuring a clean conveying environment.

[0034] Specifically, the adjustable speed conveying mechanism 3 includes a second drive shaft 31 and a second driven shaft 32. Both the second drive shaft 31 and the second driven shaft 32 are made of alloy steel and are rotatably mounted on the side wall of the sealed chamber 21. They can be installed via bearings to ensure flexible rotation. A main drive roller 33 is fixedly mounted on the second drive shaft 31. The main drive roller 33 is generally cylindrical and has an anti-slip surface, such as with anti-slip textures. A driven roller 34 is fixedly mounted on the second driven shaft 32. The driven roller 34 has a similar structure to the main drive roller 33. A conveyor belt 35 is installed between the main drive roller 33 and the driven roller 34. The conveyor belt 35 can be a rubber belt or a woven belt. The conveyor belt 35 is positioned above the two slag conveying belts 25 to facilitate receiving raw materials from the feed inlet 211. A second drive component 36 is provided on the outside of the sealed chamber 21. The second drive component 36 can be a variable frequency motor. The output shaft of the variable frequency motor is connected to the first drive shaft 23 via belt drive. By adjusting the frequency of the variable frequency motor, the rotation speed of the second drive shaft 31 can be changed, thereby realizing the adjustment of the conveying speed of the conveyor belt 35.

[0035] This configuration allows the conveyor belt 35 to dynamically adjust the feed rate according to the operating conditions of the downstream smelting equipment, avoiding situations such as overfeeding causing blockages or insufficient feed causing material shortages. When the downstream equipment requires more raw materials, the rotation speed of the second drive component 36 is increased, and the conveyor belt 35 speeds up the conveying process; when the demand from the downstream equipment decreases, the rotation speed of the second drive component 36 is reduced, and the conveyor belt 35 slows down the conveying process.

[0036] Specifically, refer to Figure 2 , Figure 5The adaptive correction mechanism 4 includes a fixed plate 41, which is generally a metal plate and is fixed to the two side walls of the sealed chamber 21 by bolts at both ends. A fixed seat 42 is fixedly mounted on the fixed plate 41. The fixed seat 42 can be a cast metal seat and is connected to the fixed plate 41 by welding or bolts. A hinge frame 43 is hingedly mounted on the fixed seat 42. The hinge frame 43 is welded from a metal rod and has a certain strength and flexibility. A first rotating shaft 44 is fixedly mounted on the hinge frame 43. The first rotating shaft 44 is usually a carbon steel shaft and is fixed to the hinge frame 43 by a key connection. Second rotating shafts 45 are fixedly mounted at both ends of the hinge frame 43, and the second rotating shafts 45 have a similar structure to the first rotating shaft 44. A bottom conveyor roller 46 is rotatably mounted on the first rotating shaft 44, and side conveyor rollers 47 are rotatably mounted on the second rotating shafts 45. The bottom conveyor roller 46 and the two side conveyor rollers 47 are rubber-coated rollers. The rubber coating has good friction and elasticity, and can better contact the conveyor belt 35. The bottom conveyor roller 46 and the two side conveyor rollers 47 are in contact with the bottom of the conveyor belt 35. When the conveyor belt 35 deviates from its designated path, it exerts a lateral force on the side conveyor rollers 47. Telescopic members 48 are provided on both sides of the hinge frame 43. The telescopic members 48 can be hydraulic or electric telescopic rods. The fixed end of the telescopic member 48 is hinged to the fixed plate 41, and the telescopic end of the telescopic member 48 is hinged to the outer end of the second rotating shaft 45. When the conveyor belt 35 deviates from its designated path, it drives the side conveyor rollers 47 to rotate, causing the hinge frame 43 to swing. The telescopic members 48 sense this change and adjust the positions of the side conveyor rollers 47 and the bottom conveyor roller 46 through their telescopic movements, thereby correcting the deviation of the conveyor belt 35.

[0037] Through the coordinated action of various components, the adaptive correction mechanism 4 can monitor the operating status of the conveyor belt 35 in real time and adjust its position in a timely manner to ensure that the conveyor belt 35 always runs on the correct track, thereby reducing the occurrence of equipment failures and improving the stability of operation.

[0038] Specifically, refer to Figure 2 , Figure 3The anti-clogging and material equalization pretreatment mechanism 5 includes a material conveying frame 51, which is generally welded from sheet metal and is fixedly installed on the sealed chamber 21 corresponding to the feed inlet 211, and can be connected by bolts. A feed hopper 52 is fixedly installed on the top of the material conveying frame 51. The feed hopper 52 is funnel-shaped, facilitating the concentrated pouring of raw materials. A third rotating shaft 53 and a fourth rotating shaft 54 ​​are rotatably installed on the side wall of the material conveying frame 51. The third rotating shaft 53 and the fourth rotating shaft 54 ​​are made of alloy steel and are mounted on the side wall of the material conveying frame 51 by bearings. Crushing rollers 55 are fixedly installed on the third rotating shaft 53 and the fourth rotating shaft 54 ​​respectively. The surface of the crushing rollers 55 has sharp crushing teeth, which can crush agglomerated raw materials. The other ends of the third rotating shaft 53 and the fourth rotating shaft 54 ​​extend out of the feed frame 51, respectively. A first spur gear 56 is fixedly mounted on the other end of the third rotating shaft 53, and a second spur gear 57 is fixedly mounted on the other end of the fourth rotating shaft 54. The first spur gear 56 and the second spur gear 57 mesh and drive each other. When one rotates, it drives the other to rotate in the opposite direction. A protective cover 58 is provided on the outside of the first spur gear 56 and the second spur gear 57. The protective cover 58 is made of metal plate and is fixed to the outside of the feed frame 51 by bolts, which serves to protect the gears and prevent debris from entering. A third driving component 59 is fixedly mounted on the outside of the protective cover 58. The third driving component 59 can be a motor. The other end of the third rotating shaft 53 is connected to the driving end of the third driving component 59. When the third driving component 59 is started, it drives the third rotating shaft 53 to rotate, which in turn drives the fourth rotating shaft 54 ​​to rotate through gear transmission, causing the two crushing rollers 55 to rotate in opposite directions to crush the raw materials.

[0039] Reference Figure 3 , Figure 4Four fixing blocks 60 are fixedly installed on the inner wall of the material handling frame 51. These fixing blocks 60 are typically rubber or plastic blocks, serving as buffers and supports. The four fixing blocks 60 are positioned below the crushing roller 55. A screen plate 61 is inclinedly installed above the four fixing blocks 60, with evenly distributed screen holes for screening raw materials. Long springs 62 and short springs 63 are installed between the screen plate 61 and the four fixing blocks 60. These springs have a certain degree of elasticity, allowing the screen plate 61 to vibrate. A limit plate 64 is fixedly installed at the bottom of the screen plate 61, limiting excessive vibration. A drive shaft 65, typically a carbon steel shaft, is fixedly installed on the limit plate 64 and connected to it via a key. An eccentric block 66 is fixedly installed on the drive shaft 65. When the eccentric block 66 rotates, it creates an eccentric effect, causing the screen plate 61 to vibrate. A drive unit 67, which can be a motor, is installed on the outer side of the feed frame 51. The drive end of the drive unit 67 is connected to the transmission shaft 65 via a universal coupling 68. When the drive unit 67 is started, it drives the transmission shaft 65 to rotate, and the eccentric block 66 rotates accordingly, causing the screen plate 61 to vibrate and screen the raw materials. A slag discharge port 69 is provided on the feed frame 51 corresponding to the screen plate 61. Unqualified large pieces of raw materials are discharged through the slag discharge port 69.

[0040] The anti-blocking and material equalization pretreatment mechanism 5 crushes the agglomerated raw materials with crushing roller 55 and screen plate 61 screens and vibrates the raw materials to equalize them, effectively preventing material blockage, ensuring the uniformity of conveyed raw materials, and improving the stability of subsequent smelting reactions.

[0041] The implementation principle of this embodiment is as follows: This raw material conveying device integrates the functions of multiple mechanisms. The sealed dustproof conveying shell mechanism 2 provides a closed conveying environment, preventing dust overflow and reducing environmental pollution and raw material loss. The adjustable speed conveying mechanism 3 can dynamically adjust the feeding speed according to the working conditions of the downstream equipment, ensuring the balance of material supply and avoiding material blockage and interruption. The adaptive correction mechanism 4 monitors and corrects the deviation of the conveyor belt 35 in real time, improving the stability of equipment operation and reducing the failure rate. The anti-blockage and uniform material pretreatment mechanism 5 crushes, screens, and uniformizes the raw materials, preventing material blockage and ensuring the quality and uniformity of the conveyed raw materials, thereby improving the stability of subsequent smelting reactions and product quality. Compared with traditional conveying equipment, this device has been improved in many aspects, better meeting the needs of modern industrial refined, continuous, and green raw material conveying production. Example 2

[0042] The difference between this embodiment and the previous embodiment is that the slag conveying belt 25 of the sealed dustproof conveying shell mechanism 2 can be replaced by a chain drive belt. The chain drive belt includes chain links and chain plates. The chain links are made of high-strength steel and connected in a ring shape by pins. The chain plates are mounted on the chain links and are used to carry waste slag, etc. Compared with the rubber slag conveying belt 25, the chain drive belt has higher strength and wear resistance, can withstand greater loads, and is suitable for conveying heavier or harder waste slag. At the same time, the chain drive belt has higher transmission efficiency, is less prone to slippage, and ensures the stability of slag conveying.

[0043] The implementation principle of this embodiment is as follows: replacing the rubber slag conveying belt 25 with a chain drive belt improves the performance of the sealed dustproof conveying shell mechanism 2. The high strength and wear resistance of the chain drive belt enable it to transport waste slag more stably, reducing the occurrence of failures such as belt damage. The higher transmission efficiency ensures the timeliness of waste slag transportation and avoids the impact of waste slag accumulation on the transportation environment. This makes the entire conveying device more reliable in terms of waste slag handling, further improving the overall efficiency and stability of the device, and is an improvement over the existing technology in the selection of conveying components.

[0044] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this application.
