Description

Technical Field

[0001] The utility model relates to vertical furnace production, in particular to a vertical furnace feeding system, belonging to the technical field of steel metallurgy. Background Art

[0002] Steel is an important food for industry, an important guarantee for construction, and an important support for the economy. As the most important raw material industry, the steel industry provides steel products that meet the needs of social development, national security, and people's lives. There are basically two processes for the manufacture of steel. One of the important processes is the production of pig iron. Blast furnace ironmaking is the main ironmaking process used in China. The iron-containing charges loaded into the blast furnace are mainly natural rich iron ore (lump ore), sintered ore and pelletized ore. Natural rich iron ore is becoming increasingly scarce, requiring the production of a large amount of high-grade concentrate. In order to improve the technical and economic indicators of mineral processing, iron ore needs to be finely ground, but too fine concentrate powder is difficult to sinter, and roasting pellets is an effective way to process finely ground concentrate.

[0003] The vertical furnace is the earliest equipment used for roasting pellets. It has played a pioneering role in the history of the development of pellet production technology because of its simple process, low investment, high thermal efficiency, and convenient operation and maintenance. The equipment for batching, mixing, ball making, and green ball screening of the vertical furnace pelletizing method are the same as those of other pelletizing methods. The feeding system of the vertical furnace must be able to distribute the green balls loosely, evenly, and continuously into the surface of the material column at the furnace mouth without breaking them, and the distribution point must be flexible and adjustable. In the existing vertical furnace feeding system, in order to facilitate the feeding of the conveyor head to the mobile distribution device, the tail wheel of the belt conveyor is on the first platform, the vertical furnace top and the mobile distribution device are set on the second platform, and the belt conveyor drive part and head frame are set on the third platform. The third platform is located above the second platform, mainly for fixing the head wheel support frame, drive roller, and drive device bracket. The green balls to be fed to the vertical furnace are transported to the third platform by the belt conveyor, and then unloaded to the mobile feeding device on the second platform through the head wheel, and then the green balls are fed to the vertical furnace for roasting.

[0004] The existing vertical furnace feeding system requires a three-layer platform, and the head wheel support frame, drive roller, and drive device bracket are separately stacked on a smaller third-layer platform. The overall structure is complex, the investment cost is high, and maintenance is difficult; in addition, the position of the redirection roller is fixed and cannot be flexibly adjusted, and it is impossible to cope with the stable connection between the drive roller and the belt under long-term working conditions. Furthermore, when unloading from the head of the belt conveyor, the material is easily ejected from the mobile feeding device, thereby forming a pile area on the platform that is difficult to clean. Utility Model Content

[0005] In view of the problems in the prior art that the existing vertical furnace feeding system has complex structure, difficult maintenance, poor flexibility in redirection adjustment, etc., the utility model provides a vertical furnace feeding system, which integrates the head wheel support frame, the driving roller and the driving device support frame into one, and then can achieve stable feeding of materials to the vertical furnace by only setting up two platforms. The overall structure is simplified while ensuring the stability of the system, and due to the simplification of the structure, the space occupancy is alleviated, which greatly reduces the difficulty of manual maintenance; in view of the problem of poor flexibility in redirection adjustment, independently adjustable redirecting rollers are respectively arranged at the upstream and downstream of the driving roller, so as to ensure the stability of the connection between the driving roller and the belt under long-term working conditions, and then ensure the stability of material feeding, which is conducive to ensuring the stability of the vertical furnace distribution.

[0006] In order to achieve the above technical objectives, the technical effects adopted by the utility model are as follows:

The head wheel is arranged on the second platform through an integrated support frame and is located above the feed port of the vertical furnace. The driving roller is located between the tail wheel and the head wheel. The conveyor belt is connected to the tail wheel, the head wheel and the driving roller in a closed manner, wherein the cylinder surface of the driving roller is in contact with the inner belt surface of the belt body at the lower side of the conveyor belt.

[0010] Preferably, the vertical beam includes a first fixed beam, a second fixed beam and a third fixed beam. The first fixed beam is arranged between the bottom frame and the top frame on the side close to the vertical furnace. The second fixed beam is arranged between the bottom frame and the top frame on the side away from the vertical furnace.

[0014] Preferably, the system further comprises a second diagonal brace. The upper end of the second fixed beam passes upward through the top frame and then protrudes above the surface of the top frame. The upper end of the second diagonal brace is connected to the upper part of the second fixed beam, and the lower end thereof extends downwardly in a direction close to the vertical furnace and then is connected to the upper surface of the top frame.

[0015] Preferably, the system further comprises a third diagonal brace, the lower end of which is connected to the upper part of the third fixed beam, and the upper end of which extends obliquely upward toward the vertical furnace and is connected to the lower surface of the top frame.

The front redirecting roller is arranged on the vertical beam on the upper side of the driving roller, and the rear redirecting roller is arranged on the vertical beam on the side of the driving roller close to the vertical furnace, and the cylinder surfaces of the front redirecting roller and the rear redirecting roller are both in contact with and connected to the outer belt surface of the belt body on the lower side of the conveyor belt. By locating the front redirecting roller and the rear redirecting roller respectively upstream and downstream of the driving roller, the contact surface between the driving roller and the belt can be increased, effectively preventing the occurrence of idling of the belt conveyor.

[0017] Preferably, two first vertical chutes or two first vertical racks are provided on the third fixed beam located on both sides of the driving roller in the axial direction. The two axial ends of the front redirecting roller are respectively installed in the two first vertical chutes through the first sliders or meshed on the two first vertical racks through the first gears. The vertical height of the front redirecting roller is adjusted by sliding the first slider in the first vertical chutes or rolling the first gear on the first vertical racks. By increasing the adjustability of the positions of the front redirecting roller and the rear redirecting roller, the size and firmness of the contact surface between the belt and the driving roller can be flexibly adjusted to ensure the stability of belt feeding.

[0019] Preferably, according to the feeding direction of the belt feeder, a first cleaner and a second cleaner are sequentially arranged on the outer belt surface of the conveyor belt downstream of the highest point of the head wheel.

[0023] Preferably, the first cleaner is a P-type cleaner, the second cleaner is an H-type cleaner, and the third cleaner is a space cleaner.

[0024] Preferably, a movable material distribution device is provided on the feed port of the vertical furnace, a material guide device is provided between the movable material distribution device and the head wheel, and a material flow regulating plate is provided inside the material guide device. The material flow regulating plate is used to change the material falling angle so as to adjust the material flow direction at any time and make the materials on both sides of the belt evenly distributed.

[0025] Preferably, a maintenance passage is preset on a side of the side wall of the integrated support frame close to the vertical furnace.

[0026] In the utility model, an integrated support frame is formed by optimizing the structure of the split support frame in the prior art, and the support frame and the track of the mobile material distribution device share a platform, thereby facilitating the maintenance of the mobile material distribution device and the vertical furnace and reducing the cost of material transportation; in addition, since the number of platform settings in the original device is reduced, the investment cost is further reduced.

[0027] In the utility model, the stability of the integrated support frame in the working state is achieved by means of three sets of diagonal braces in a staggered design. Moreover, when the machine is shut down for maintenance, the stability of the support frame structure can be maintained after removing a set of diagonal braces at the front end.

[0028] In the utility model, the integrated support frame adopts a large rectangular support frame, which is mainly composed of a bottom frame, a top frame, a vertical beam, a diagonal brace, etc. The head wheel is fixed to the front end of the upper cross bar of the top frame (i.e., close to one end of the vertical furnace). Since the head wheel is arranged relatively high, three diagonal braces are added to the top frame to fix the upper cross bar, thereby increasing the overall stability of the support; the driving roller is fixed to the third fixed beam in the middle of the support, and a front redirecting roller and a rear redirecting roller are respectively arranged on the front and rear sides of the driving roller. By adjusting the positions of the front and rear redirecting rollers, the contact area between the driving roller and the conveyor belt is increased to avoid the phenomenon of the conveyor belt slipping. The fixing method between the first fixed beam and the first diagonal brace and other components is a detachable connection (for example, a detachable bolt connection). In addition, the fixing method between other components is a more solid welding. That is, since the first fixed beam and the first diagonal brace close to the head wheel are fixed to the support frame by bolts, when the mobile material distribution device or the vertical furnace needs to be repaired, the first fixed beam and the first diagonal brace can be removed for manual maintenance (the cold water beam is evenly arranged in the vertical furnace feed cover. When the cold water beam is repaired, it needs to be pulled out from the feeding equipment end. After the feeding conveyor is stopped, the first fixed beam and the first diagonal brace are removed, and the cold water beam can be smoothly pulled out. After the maintenance is completed, the first fixed beam and the first diagonal brace can be fixed to the bracket by bolts). Since the overall structure of the support frame is optimized, when the belt conveyor is stopped, the stability of the overall structure will not be affected by removing the first fixed beam and the first diagonal brace on the left side.

[0029] The vertical spacing between the front redirecting roller and the driving roller is adjustable, specifically, by arranging sliders at the two axial ends of the front redirecting roller, and vertical slide grooves are opened on the beam body of the third fixed beam corresponding to the two axial ends of the front redirecting roller. The vertical spacing between the front redirecting roller and the driving roller is adjusted by sliding the slider in the vertical slide groove. According to the direction of the conveyor belt, the conveyor belt first detours from the upper surface of the front redirecting roller from top to bottom (that is, the outer surface (or lower surface) of the conveyor belt body, that is, the belt surface directly in contact with the material) contacts the upper drum surface of the front redirecting roller), and then detours from the front side and the lower surface of the driving roller from bottom to top after tilting downward in the reverse direction (that is, the inner surface (or upper surface) of the conveyor belt body, that is, the belt surface not in contact with the material) contacts the lower drum surface of the driving roller). Therefore, when the vertical spacing between the front redirecting roller and the driving roller changes, the contact area between the drum surface on the front side of the driving roller and the conveyor belt will change, and then the magnitude of the interaction force between the driving roller and the conveyor belt will also change. That is, by adjusting the vertical distance between the two, the interaction force between the driving roller and the conveyor belt can be adjusted to avoid the conveyor belt slipping.

[0030] Similarly, the vertical spacing and horizontal spacing between the rear redirecting roller and the driving roller are also adjustable. The rear redirecting roller is arranged on the second fixed beam through a vertical slider and a vertical slide groove structure, and the vertical height of the rear redirecting roller is adjusted by the group of vertical sliders and vertical slide grooves. At the same time, by adding a horizontal slide rail and a horizontal slider between the slide groove and the rear redirecting roller (the rear redirecting roller moves horizontally on the horizontal slide rail through the horizontal slider, and the horizontal slide rail moves up and down in the vertical slide groove of the second fixed beam through the above-mentioned slider, thereby adjusting the vertical height of the rear redirecting roller), the horizontal displacement of the rear redirecting roller is adjusted. In other words, the utility model can realize the precise adjustment of the contact area between the conveyor belt and the driving roller surface through the coordinated adjustment of the front and rear redirecting rollers, which is conducive to improving the stability of the mutual force between the conveyor belt and the driving roller, and can also effectively ensure uniform feeding under the premise of changes in material weight, thereby ensuring the stability of vertical furnace feeding.

[0031] In the utility model, a material guiding device is provided at the material discharge position of the head wheel to effectively prevent the material from being ejected during the transfer to the material distribution device, and the material guiding device contains a material flow regulating plate, which can evenly distribute the material to the material distribution device.

[0032] In the utility model, a maintenance passage is preset on the side of the integrated support frame near the vertical furnace for workers to use for inspection. For example, the passage is surrounded by patterned steel plates to prevent scattered materials from injuring people. It is convenient for workers to inspect and also increases the safety protection effect during inspection.

[0033] In the utility model, a set of P-type cleaners and H-type cleaners are arranged beside the head wheel to clean the sticky materials on the conveyor belt to the mobile feeding device. A set of H-type cleaners and H-type cleaners are arranged beside the front redirection roller, a set of P-type cleaners and H-type cleaners are arranged beside the driving roller, and a set of empty section cleaners are arranged near the rear redirection roller to effectively remove the materials stuck on the belt surface.

[0034] Compared with the prior art, the beneficial technical effects of the utility model are as follows:

[0035] 1: The utility model uses an integrated support frame to replace the original dispersed support setting through structural optimization, which has the characteristics of a more stable support frame structure, and can reduce the number of platforms, reduce space occupation and save equipment investment costs.

[0036] 2: The utility model provides front and rear redirecting rollers with adjustable positions on the upstream and downstream conveyor belts of the driving roller, respectively, so that the contact area between the driving roller and the conveyor belt can be flexibly adjusted according to the changes in working conditions, thereby ensuring the stability of the mutual force between the driving roller and the conveyor belt, and realizing stable feeding of the vertical furnace.

[0037] 3: The utility model also has the advantages of simple structure, convenient operation, convenient maintenance, strong stability, low equipment investment cost and strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS
