Description
Technical Field
[0001] This invention relates to the field of pellet roasting technology, and in particular to an environmentally friendly integrated material distribution system and belt roasting machine for laying bottom material, edge material, and accident material. Background Technology
[0002] The bottom material, edge material, and emergency material systems, along with the green pellet feeding system, form the foundation of the entire belt roaster pellet feeding production process. The bottom material, edge material, and emergency material systems are the most significant factors affecting the lifespan of the trolley and the integrity of the production system when the green pellet feeding system malfunctions. Furthermore, they influence the quality of the finished pellets during production fluctuations. Therefore, a reasonable configuration of the bottom material, edge material, and emergency material systems is fundamental to stable pellet feeding, improved finished pellet quality, and guaranteed trolley lifespan.
[0003] The material surface of the trolley is an important component of the hot air circulation system of the entire pelletizing (sintering) process. The flatness of the material surface is a major factor affecting the system's heat utilization efficiency and the utilization efficiency of the process fans. Therefore, properly controlling the flatness of the material surface and reducing the fluctuation range of the material surface height difference is the basis for ensuring the utilization efficiency of the hot air system.
[0004] The hot air circulation system is the foundation of energy saving and carbon emission reduction in the entire pellet (sintering) roasting system. From the moment the green pellets are placed onto the roasting machine trolley, the entire thermal process, from drying to cooling, relies primarily on the hot air circulation system for heat transfer. The uniformity of pellet distribution on the trolley directly affects the utilization efficiency of the hot air system, which in turn influences fuel and electricity consumption. Therefore, improving the bottom and edge feeding system and optimizing the uniformity of pellet distribution are fundamental to improving hot air utilization efficiency, thereby reducing fuel and electricity consumption and carbon emissions.
[0005] Traditional pellet (sintering) calcining machines have separate bottom material laying systems, edge material laying systems, and emergency material laying systems, such as... Figure 6 , Figure 7 and Figure 8As shown, the system consists of three parts: the base material system 001, the edge material system 002, and the emergency material system 003. Due to the large distance between the base material, green balls, and emergency material, there is a time difference in material distribution adjustment. This causes fluctuations in the height of the material surface on the trolley during material distribution adjustments, affecting the flatness of the material surface. Furthermore, when there are significant fluctuations in the amount of green balls, or when the green balls are interrupted and the emergency material system 003 needs to be activated, due to inherent design flaws in the emergency material system 003 (the emergency material chute is approximately 50% the width of trolley 1 and the height difference is greater than the material thickness of trolley 1) and the time difference issue, there are large fluctuations in the thickness of the emergency material distribution. This reduces the efficiency of the ventilation system, shortens the service life of the trolley, and affects the quality of the finished balls. The base material system 001 and the emergency material system 003 are designed separately from the green ball distribution system, making it difficult to coordinate and accurately control the material thickness. When the green ball distribution stops, the emergency material system 003 also cannot accurately control the height of the emergency material, which will affect the flatness of the material surface on the trolley and the uniformity of material distribution. For example, a green pellet screening device and trolley disclosed in patent (publication number: CN215844053U) are equipped with two chutes and two electric sector valves for both the bottom material laying device and the edge material laying device, and one chute and one electric sector valve for the emergency material laying device, for a total of five chutes and five electric sector valves. Correspondingly, the bottom and edge emergency material bins also need to be equipped with five discharge ports. This traditional bottom material laying system, edge material laying system and emergency material laying system have a very complex structure. Moreover, the bottom material laying device is set separately from the edge material laying device and the emergency material laying device, which makes it inconvenient to coordinate and cooperate to accurately control the material thickness. The separate design of the bottom material laying device from the edge material laying device and the emergency material laying device will affect the flatness of the material surface on the trolley and the uniformity of material distribution. In the event of an accident, the emergency material laying device cannot accurately control the height of the emergency material. In addition, dust will be generated when the pellets are put into the trolley, causing environmental pollution. Summary of the Invention
[0006] To address the problems existing in the prior art, this invention provides an environmentally friendly integrated material distribution system and belt roasting machine for laying bottom material, edge material, and accident material. The system has a simple structure, can improve the flatness of the material surface on the trolley and the uniformity of material distribution, and can quickly and accurately control the height of the accident material in case of an accident, as well as prevent material dust from polluting the environment.
[0007] To achieve the above-mentioned objectives, the technical solution of the present invention is as follows:
[0008] An environmentally friendly integrated material distribution system for laying base material, edge material, and accident material is installed on the trolley of a belt roasting machine. The trolley has side panels on both sides, including:
[0009] A device for handling accidental material spillage at the base and edge, comprising:
[0010] chute;
[0011] The guide chute has its front end connected to the lower end of the chute. The guide chute is set on the trolley and located between the sidewalls of the trolley. The upper end of the guide chute is closed and the lower end is open.
[0012] A material distribution valve is disposed at the rear end of the material guide trough, and gaps are respectively provided between the two sides of the material distribution valve and the two side walls of the material guide trough;
[0013] The first side material guide plate is provided on both sides of the rear end of the material distribution valve, and the first side material guide plate is parallel to the side of the trolley.
[0014] A roller feeder is installed above the trolley. A chute is installed on the lower side of the roller feeder. The chute is inclined with the front higher than the back, and the vertical projection of its lower end is located between the two first edge material guide plates.
[0015] The bottom material and edge material accident hopper is located above the chute and is connected to the chute.
[0016] Furthermore, the top of the chute is provided with a feed inlet on each side of the center line in the front-rear direction, and the bottom material and side material accident hopper is provided with a corresponding discharge outlet.
[0017] Furthermore, a horizontal smearing plate is provided on the material guide groove, the lower end of the smearing plate is horizontally positioned, and the smearing plate is slidably and fixedly connected to the side walls of the material guide groove.
[0018] Furthermore, vertical second side material guide plates are respectively provided on the upper middle part of both sides of the front end of the material distribution valve, and the front end of the second side material guide plates is inclined away from the outside of the material distribution valve.
[0019] Furthermore, the lower ends of the chute 31 abut against the inner rear ends of the corresponding first side guide plates 24 on both sides.
[0020] Furthermore, the valve plate of the fabric valve is an arc-shaped valve plate.
[0021] Furthermore, the lower part of the chute is designed with a backward arc-shaped bend.
[0022] The present invention also provides a belt roasting machine, including the above-mentioned integrated environmental protection material distribution system for base material, edge material, and accident material.
[0023] The present invention has at least the following beneficial effects:
[0024] 1. The device provided by this invention moves the traditional emergency material system and edge material system forward and merges them with the bottom material system to form a bottom material, edge material, and emergency material device. It has only one chute and a material distribution valve, which is simple in structure and reduces the difficulty of structural assembly. At the same time, the bottom material and emergency material outlets are extended and moved to the bottom of the roller distributor through the guide chute. The material distribution valve is set at the rear end of the guide chute, and there are gaps between the two sides of the material distribution valve and the two side walls of the guide chute. A first edge material guide plate is set on each side of the rear end of the material distribution valve. The first edge material guide plate is parallel to the side of the trolley. The bottom material or emergency material, edge material, and green balls can be distributed simultaneously. When adjusting the distribution operation, there is no time difference between the distribution of the bottom material or emergency material, edge material, and green balls. This simplifies the trolley operation control system, makes the material thickness control more precise and simple, improves the flatness of the material surface on the trolley and the uniformity of distribution in normal production and emergency conditions, improves the utilization efficiency of the ventilation system in emergency conditions, eliminates air short circuits, and extends the life of the trolley. The material distribution valve is located at the rear end of the feed chute. By controlling the thickness of the emergency material, precise and uniform control of the material thickness can be achieved, improving the utilization efficiency of the ventilation system under emergency conditions, preventing air short circuits, and ensuring the life of the trolley grate bars. The front end of the first edge material guide plate is close to the side of the material distribution valve. The edge material moves backward under the action of the upper surface of the trolley and the side of the trolley, solving the problem of easy blockage in traditional edge material chutes due to narrow outlets and reliance solely on the gravity flow of the pellets.
[0025] 2. The feed chute is closed at the top and open at the bottom. Pellet ore falling from the chute lands on the trolley. The trolley moves backward, carrying the pellet ore along the feed chute towards its rear end. When the pellet ore falls from the chute onto the trolley, it may accumulate. When the pellet ore moves with the trolley to the junction of the closed upper end of the feed chute and the rear wall of the bottom material chute, the upper end of the feed chute will push away the pellet ore whose accumulation height exceeds the height of the upper end of the feed chute, spreading the pellet ore out and achieving initial leveling. When the pellet ore lands on the trolley, it generates dust. The closed upper end of the feed chute can control the dust within the feed chute, preventing dust from scattering on site and causing environmental pollution.
[0026] 3. Traditional silos have five discharge ports, while the bottom material and side material emergency silos have only two discharge ports, which greatly simplifies the silo structure, reduces the difficulty of structural assembly, and reduces the number of control equipment and dust removal points.
[0027] 4. A horizontal smearing plate is provided on the guide trough. The lower end of the smearing plate is horizontally set, and the two ends of the smearing plate are slidably and fixedly connected to the side walls of the guide trough. By adjusting the appropriate height of the smearing plate in the guide trough, when the trolley carrying pellets passes through the smearing plate, the accumulated pellets can be smoothed and the pits can be filled, which is beneficial to the flatness and uniformity of the material surface on the trolley.
[0028] 5. The valve plate of the feeding valve is an arc-shaped valve plate. The concave surface of the arc-shaped valve plate can guide the pellets to be laid from the bottom of the trolley upwards, improving the quality of the bottom material or emergency material placement. This design can also improve the wear resistance of the valve plate and extend its service life.
[0029] 6. The lower part of the chute plate is designed with a backward arc shape, which can reduce the speed at which the green balls fall to the bottom material and reduce the impact of the impact between the green balls and the bottom material on the flatness of the material surface on the trolley and the uniformity of the material distribution.

[0043] like Figure 1 , Figure 2 As shown, this invention provides an environmentally friendly integrated material distribution system for base material, edge material, and accident material, which is installed on the trolley 1 of a belt roaster, as follows: Figure 2 As indicated by the arrow, the trolley 1 moves from front to back. The trolley 1 has side rails 11 on both sides, including:
[0044] The bottom material and edge material accident material device 2 includes
[0045] Sluice 21; connected to bottom material, edge material, and emergency material bin 4, used to input pellet ore and provide raw materials for bottom material, edge material, and emergency material.
[0046] The guide chute 22 is connected at its front end to the lower end of the chute 21. The guide chute 22 is open at its front end and connected to the lower end of the chute 21. The guide chute 22 is positioned on the trolley 1 and between the trolley's sidewalls 11. The upper end of the guide chute 22 is closed, and the lower end is open. Pellet ore falling from the chute 21 lands on the trolley 1. As the trolley moves backward, it carries the pellet ore along the guide chute 22 towards its rear end. When the pellet ore falls from the chute 21 onto the trolley 1... There will be some accumulation. When the pellets move with the trolley 1 to the junction of the upper closed end of the guide chute 22 and the rear wall of the bottom material accident chute 21, the upper end of the guide chute 22 will push the pellets whose accumulation height exceeds the height of the upper end of the guide chute 22, so that the pellets are spread out and achieve the initial leveling effect. When the pellets fall onto the trolley 1, dust will be generated. The upper closed end of the guide chute 22 can control the dust in the guide chute 22 and prevent the dust from scattering on site and causing environmental pollution.
[0047] A feeding valve 23 is located at the rear end of the feed chute 22. Pellet ore passes through the opening of the feeding valve 23. By adjusting the opening of the feeding valve 23, a base material or emergency material is formed. The feeding valve 23 includes two feeding valve side walls 231 and a valve plate 232. The upper ends of the two feeding valve side walls 231 are fixed to the upper end of the feed chute 22, and the lower ends are flush with the lower end of the feed chute 22. The two feeding valve side walls 231 are respectively provided with gaps between the two side walls of the feed chute 22 to allow the pellet ore to pass through and prepare for the formation of subsequent edge material. The valve plate 232 is located between the two feeding valve side walls 231. By adjusting the distance between the bottom end of the valve plate 232 and the trolley 1, i.e., the opening, the thickness of the base material or emergency material passing through can be adjusted.
[0048] The first edge material guide plate 24 is provided on both sides of the rear end of the material distribution valve 23. The first edge material guide plate 24 is parallel to the trolley side plate 11. The pellets flow out from the gap between the two sides of the material distribution valve 23 and the two side walls of the guide trough 22, and pass through the channel formed by the first edge material guide plate 24 and the trolley side plate 11 to form edge material.
[0049] A roller feeder 3 is installed above the trolley 1 and is used to place raw balls. A chute 31 is installed on the lower side of the roller feeder 3. The chute 31 is inclined with the front higher than the back, and the vertical projection of its lower end is located between the two first edge material guide plates 24.
[0050] The bottom material and edge material accident hopper 4 is located above the chute 21 and is connected to the chute 21.
[0051] The method of using this invention is as follows:
[0052] During normal production:
[0053] The pellets fall from the chute 21 and pile up on the upper surface of the trolley 1, forming a pellet stockpile inside the chute 21. As the trolley 1 moves backward, the pellets in the stockpile inside the chute 21, under the action of the upper surface of the trolley 1, move backward with the trolley 1 and enter the guide chute 22. They move backward along the guide chute 22 to the distribution valve 23. The pellets passing through the gap between the valve plate 232 of the distribution valve 23 and the trolley 1 move backward, forming a highly precisely controlled bottom material. The pellets passing between the two sides of the distribution valve 23 and the side wall of the guide chute 22, under the action of the upper surface of the trolley 1 and the trolley sidewall 11, move backward with the trolley 1 along the gap between the first side material guide plate 24 and the trolley sidewall 11 to the side of the chute plate 31, forming side material. Together with the green pellets distributed by the roller distributor 3 through the chute plate 31, the trolley material is distributed and enters the belt roaster to produce finished pellets.
[0054] Accident status:
[0055] In the event of an accident in the green pellet feeding process, such as a sudden stop in material supply, and the roller feeder 3 is unable to feed green pellets, the feeding valve 23 adjusts its opening according to the amount and speed of green pellets, increasing the thickness of the base material to ensure that the overall material thickness of the trolley remains constant. Because the opening of the feeding valve 23 is adjustable, the width of the base material and the edge material together are exactly the same as the width of the trolley 1. Furthermore, the feeding valve 23 is installed at the outlet end of the guide chute 22, close to the first edge material guide plate 24, which can precisely control the material thickness of the trolley, ensuring the uniformity of the material thickness on the trolley and preventing problems such as excessive local airflow affecting the drying and roasting of green pellets and damaging the life of the trolley.
[0056] In summary, the device provided by the present invention moves the traditional emergency material system and edge material system forward and merges them with the bottom material system to form a bottom material, edge material, and emergency material device 2. It has only one chute 21 and a material distribution valve 23, which is simple in structure and reduces the difficulty of structural assembly. Simultaneously, the bottom material and emergency material outlets are extended and moved to below the roller distributor 3 via the guide chute 22. The distribution valve 23 is located at the rear end of the guide chute 22, and gaps are provided between the two sides of the distribution valve 23 and the two side walls of the guide chute 22. A first side material guide plate 24 is provided on each side of the rear end of the distribution valve 23. The first side material guide plate 24 is parallel to the trolley sidewall 11. The bottom material or emergency material, side material and green balls can be distributed simultaneously. When adjusting the distribution operation, the time difference between the distribution of the bottom material or emergency material, side material and green balls is very small, which simplifies the trolley operation control system and makes the material thickness control more precise and simple. It can improve the flatness of the trolley material surface and the uniformity of distribution during normal production and emergency conditions, improve the utilization efficiency of the wind system in emergency conditions, prevent wind short circuits, and extend the trolley life. The material distribution valve 23 is located at the rear end of the guide chute 22. By controlling the thickness of the emergency material through the material distribution valve 23, precise and uniform control of the emergency material thickness can be achieved, improving the utilization efficiency of the ventilation system under emergency conditions, preventing air short circuits, and ensuring the service life of the trolley grate bars. The front end of the first edge material guide plate 24 is close to the side of the material distribution valve 23. The edge material moves backward under the action of the upper surface of the trolley 1 and the trolley side plate 11, solving the problem of easy blockage in traditional edge material chutes due to narrow outlets and reliance solely on the gravity flow of the pellets.
[0057] In this embodiment, the top of the chute 21 is provided with a feed inlet 211 on both sides of the center line in the front-rear direction, which further improves the uniformity of the bottom material or emergency material distribution. The bottom material, edge material, and emergency material bin 4 is also provided with two discharge outlets 41 corresponding to the feed inlets 211, such as... Figure 3 , Figure 4 As shown, traditional silos have 5 discharge ports, while the bottom material and side material accident silo 4 has only two discharge ports, which greatly simplifies the silo structure, reduces the difficulty of structural assembly, and reduces the number of control equipment and dust removal points.
[0058] When pellets fall from the bottom material / edge material emergency hopper 4 onto the surface of the trolley 1, some accumulation may occur. As a preferred solution, a horizontal smearing plate 221 is provided on the guide chute 22. The lower end of the smearing plate 221 is horizontally positioned, and both ends of the smearing plate 221 are slidably and fixedly connected to the side walls of the guide chute 22. By adjusting the appropriate height of the smearing plate 221 on the guide chute 22, when the trolley 1 carrying pellets passes over the smearing plate 221, the accumulated pellets can be smoothed out, and the pits can be filled, which is beneficial to the flatness and uniformity of the material surface on the trolley. Furthermore, the smearing plate 221 is inclined at the front and lower at the back, which can better smooth and fill the pellets.
[0059] The pellets flow out through the gaps between the sides of the distribution valve 23 and the side walls of the guide trough 22, and travel along the channel formed by the first side material guide plate 24 and the trolley sidewall 11, forming side material. The gaps between the sides of the distribution valve 23 and the side walls of the guide trough 22 are relatively small compared to the width of the guide trough 22, which is unfavorable for the pellets to enter the gaps. As a preferred embodiment, vertical second side material guide plates 25 are respectively provided on the upper middle part of both sides of the front end of the distribution valve 23. The front ends of the second side material guide plates 25 are inclined away from the outside of the distribution valve 23, which facilitates guiding the pellets into the gaps between the sides of the distribution valve 23 and the side walls of the guide trough 22, and into the gap between the first side material guide plate 24 and the trolley sidewall 11, forming side material.
[0060] As a preferred embodiment, the lower two sides of the chute 31 abut against the inner rear end of the corresponding first edge material guide plate 24. Along the front-to-back movement direction of the trolley 1, the lower right side of the chute 31 abuts against the inner rear end of the right first edge material guide plate 24, and the lower left side of the chute 31 abuts against the inner rear end of the left first edge material guide plate 24. In this way, edge material formation and green ball delivery occur simultaneously, further improving the flatness of the trolley material surface and the uniformity of material distribution.
[0061] Typically, the valve plate of the fabric distribution valve 23 has a flat plate structure; however, as a preferred embodiment, the valve plate 232 of the fabric distribution valve 23 is an arc-shaped valve plate. Figure 5 As shown, the bottom edge of the valve plate is a straight edge, which ensures that the bottom material and emergency material surface is flat and uniform. Compared with the flat plate structure, the concave surface of the arc-shaped valve plate can guide the pellet ore to be laid from the bottom of the trolley from bottom to top, improving the laying quality of the bottom material or emergency material. This setting can also improve the wear resistance of the valve plate 232 and extend its service life.
[0062] The green ball feeder 33 feeds green balls into the roller distributor 3, which screens the green balls. The green balls that pass the screening roll down the chute 31 and fall onto the base material, while the green balls that do not pass the screening are collected by the bulk material conveyor 32. As a preferred embodiment, the lower part of the chute 31 is designed with a backward arc curve, which can reduce the speed at which the green balls fall onto the base material and reduce the impact of the green balls and the base material on the flatness of the trolley material surface and the uniformity of the material distribution.
[0063] Although the present invention has been described in detail above with specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
