Abstract

[0030] The present application is described below with reference to the accompanying drawings and specific embodiments:
[0031] Please refer to Figure 1 In a first aspect of the present application, an embodiment provides a metallurgical solid waste treatment device, which includes: a collection section 110, a material distribution section 120, a conveying section 130 and a material dispersion section 140. The collection section 110 is provided with a cavity 111a for collecting metallurgical solid waste. The collection section 110 is a container for loading metallurgical solid waste, such as a box, a cylinder, a tank, etc. The collection section 110 is arranged below the ground, so that the transport vehicle 200 can pour the metallurgical solid waste into the opening of the collection section 110 on the ground. For example, when a pit is excavated, the collection section 110 is placed in the pit at a certain height from the bottom of the pit. A mounting frame is provided to place the collection section 110, and the mounting frame is a general The rack form is adopted, with the ground as the zero plane, the top of the aggregate part 110 being at the zero plane, the transport vehicle 200 being at the zero plane and being located next to the top opening of the aggregate part 110, and the metallurgical solid waste carried by the transport vehicle 200 can be poured into the cavity 111a of the aggregate part 110 by dumping, such as by using a dump truck; the following uses a pit setting form to illustrate, and other settings can also be used, such as placing the aggregate part 110 on the ground, raising the height of the transport vehicle 200 or using a pump to increase the height; the aggregate part 110 is made of stainless steel to enhance corrosion resistance, and other materials that do not react with metallurgical solid waste can also be used.
[0032] Please refer to Figure 2The material separation part 120 includes a pusher 121, a material separation conveyor 122 and a control valve 123. The pusher 121 is used to transfer metallurgical solid waste. The pusher 121 is arranged in the material collection part 110 and can move back and forth relative to the material collection part 110. The pusher 121 can adopt a plate structure, a rod structure or other forms, as long as it is convenient to push or carry the metallurgical solid waste. For example, one side of the pusher 121 is plate-shaped, which is convenient for pushing materials, and the other side is set to be rod-shaped, which is convenient for passing through the rod hole at the corresponding position of the material collection part 110. After the rod-shaped structure extends out of the material collection part 110, it can be controlled outside the material collection part 110. The pushing member 121 moves back and forth left and right in the figure to push the metallurgical solid waste carried by the pushing member 121 from the cavity 111a into the material separation conveyor 122. The material separation conveyor 122 is used to continuously convey the metallurgical solid waste. The material separation conveyor 122 adopts the existing mechanism that can continuously convey materials. The control valve 123 is installed at the outlet of the material separation conveyor 122. The control valve 123 is used to control the material supply of the conveying part 130 and to facilitate isolation and maintenance. The control valve 123 can be a manual mechanical valve, such as a gate valve, or an electric valve, such as a solenoid valve.
[0033] The material dispersing section 140 is used to crush and disperse the metallurgical solid waste. A vertical mixer, a vertical disperser, etc. can be used. A platform frame is built on the top of the material dispersing section 140, and the discharge end 130b of the conveying section 130 is fixed on the platform frame. After the metallurgical solid waste comes out of the discharge end 130b, it directly enters the stirring chamber inside the material dispersing section 140 to be crushed and dispersed. In an optional embodiment, a rotatable dispersing blade 141 is provided in the material dispersing section 140. The dispersing blade 141 is used to apply a shear force to the metallurgical solid waste entering the material dispersing section 140. A plurality of dispersing blades 141 can be provided to fully crush and disperse the metallurgical solid waste. In this way, the material dispersing section 140 has a strong processing capacity and a good mixing effect. For example, steelmaking sludge is transported and added into the vertical mixer, and dust removal ash, blast furnace return ore, limestone powder and other low-moisture materials are added at the same time, and mixed together to meet the moisture requirements required for briquetting and enter the next process.
[0034] The conveying section 130 includes a feed end 130a and a discharge end 130b. The conveying section 130 adopts a mechanism that can convey or transport metallurgical solid waste, such as a conveyor belt conveyor, a scraper conveyor, etc. The metallurgical solid waste enters the conveying section 130 from the feed end 130a and is then discharged from the discharge end 130b. The feed end 130a is located at the outlet of the material separation conveyor 122, and the discharge end 130b is located at the entrance of the material dispersion section 140. The conveying section 130 can also be provided with another mounting frame, and the feed end 130a is fixed to the mounting frame, so that the feed end 130a is located in the pit, and the discharge end 130b is located at a position higher than the feed end 130a, and is connected to the material dispersion section 140, so that the material can be transported from a low place to a high place, and finally the metallurgical solid waste sludge is transported from the feed end 130a to the discharge end 130b and then falls into the material dispersion section 140.
[0035] Metallurgical solid waste needs to be in a more dispersed state when it is recycled repeatedly, but it is easy to clump into agglomerates, and a set of equipment and processes are needed to treat it. However, the treatment process is cumbersome and costly. For example, the various process routes for steelmaking sludge treatment require a large area for natural drying and a long time for air drying. The so-called homogenization operation also relies on grab bridge cranes or excavators to make piles and mix them. When directly participating in sintering ingredients, the proportion of steelmaking sludge must be controlled within a certain range, otherwise it will have a greater impact on the quality of the sintered ore. Using the drying process, the moisture content of the steelmaking sludge needs to be reduced from 30% to about 3% to meet the requirements of the briquetting process, which requires a lot of fuel, resulting in high energy consumption in the production line process and no product advantage.
[0036] The present application continuously transports the metallurgical solid waste through the material separation section 120, firstly transfers the metallurgical solid waste sludge to the material separation conveyor 122 at intervals and periodically through the pushing piece 121, and then continuously transports the metallurgical solid waste through the material separation conveyor 122, which can disperse the metallurgical solid waste to a certain extent, and then adjusts the conveying amount of the transferred metallurgical solid waste sludge of the conveying section 130 through the control valve 123, and transfers the metallurgical solid waste sludge to the material dispersion section 140 through the conveying section 130 for crushing and breaking up, which can effectively consume the agglomerated materials and avoid the agglomeration of metallurgical solid waste, thereby eliminating the existing drying process and cost, significantly shortening the metallurgical solid waste recovery production line, and also reducing the process cost. In addition, steelmaking sludge does not need to be stored on site, and is seamlessly connected to the steelmaking process. The application is highly adaptable to water-containing materials, and has the advantages of stable operation and low equipment accident rate. On the other hand, the application occupies a small area and has a high level of automation, avoiding the problem of a large number of drying sites and the labor intensity of manual mixing, and does not use a dryer to save investment and operating costs.
[0037] In an optional embodiment, the material dividing section 120 and the conveying section 130 are respectively provided with at least two groups, such as two groups, three groups, four groups, etc., and two groups are taken as an example for explanation here. The pushing piece 121 of each group corresponds to a material separating conveyor 122, and the control valve 123 of each group corresponds to a conveying section 130, so that each group of conveying sections 130 works independently, that is, there are two pushing pieces 121 in total, one side of the two pushing pieces 121 is arranged opposite to each other, and the other side of the two pushing pieces 121 extends out of the collecting section 110, such as the pushing pieces 121 symmetrically arranged on the left and right in the figure, so that the pushing piece 121 part located in the cavity 111a can carry or push the metallurgical solid waste to both sides of the cavity 111a, and then enter the material separating conveyor 122, and can be operated periodically. In an optional embodiment, a push plate 121a is provided on the side of the pusher 121 away from the material separation conveyor 122, that is, the edge of the pusher 121 located in the cavity 111a has a push plate 121a, which is a strip-shaped plate structure, and the push plate 121a has a wide area in contact with the metallurgical solid waste. The push plate 121a is used to apply thrust to the metallurgical solid waste in the cavity 111a when the pusher 121 moves. When the pusher 121 moves outward in the horizontal direction, the push plate 121a pushes the metallurgical solid waste toward the entrance of the material separation conveyor 122. Similarly, the conveying part 130 also works independently. As shown in the figure, two conveying parts 130 can be used, one for work and the other for standby.
[0038] In an optional embodiment, the pushing piece 121 is horizontally arranged, and the pushing piece 121 is also provided with a variable frequency drive 121b. The variable frequency drive 121b is a pneumatic cylinder or an electric cylinder, equipped with a frequency converter. The variable frequency drive 121b is used to drive the pushing piece 121 to move back and forth in the horizontal direction. The variable frequency drive 121b can provide a variable frequency drive speed, so that metallurgical solid waste can enter the material separation conveyor 122 at different speeds, and then fall to the conveying part 130 at different speeds. The stroke of the variable frequency drive 121b can be adjusted according to the size of the collection part 110. The pushing piece 121 is connected to the output rod of the variable frequency drive 121b one by one, bolted or fixed, or other fixing methods. A plurality of variable frequency drives 121b can also be set for one pushing piece 121. The pushing piece 121 and the connected variable frequency drive 121b are a group, and different groups can achieve independent operation.
[0039] In an optional embodiment, the material separation conveyor 122 includes at least two screw conveyors, and a double screw conveyor can also be used. The screw conveyor is an existing device with a spiral output shaft. The material is separated by the screw conveying shaft and can be continuously conveyed. The inlet of the screw conveyor is located in the cavity 111a, and the outlet of the screw conveyor is located outside the collecting bin 111. In this way, the screw conveyor transports the metallurgical solid waste from the collecting part 110 to the outside. The screw conveyor can perform forward and reverse steering to facilitate independent feeding of different groups of conveying parts 130, such as separate feeding or simultaneous feeding; since the material separation conveyor 122 can be set to multiple groups, the screw conveyor is also provided with multiple groups. For example, two groups of screw conveyors are provided as shown in the figure, and the metallurgical solid waste can be discharged from four outlets through the two groups of screw conveyors.
[0040] In an optional embodiment, the conveying section 130 includes a first conveyor 131 and a second conveyor 132, the first end of the first conveyor 131 is located at the exit of the material separation conveyor 122, and the second end is connected to the second conveyor 132; the second conveyor 132 is higher than the first end of the first conveyor 131, and the second conveyor 132 is located at the top opening of the material dispersion section 140; in an optional embodiment, the first conveyor 131 adopts an inclined scraper machine, and the scraper machine has a scraper. The scraper is made of stainless steel. Unlike an ordinary scraper, the scraper has a low height and a large thickness. It is shorter in the middle and higher at both ends in the length direction. A water spraying point is set near the second conveyor 132 to spray water on the scraper to prevent the occasional sticky material from sticking to the scraper, and it also serves as a means of regularly cleaning the scraper. In an optional embodiment, the first conveyor 131 has an inclined section, and the inclination angle of the inclined section is less than or equal to 45°, such as 30°, which can be adjusted as needed. The material inlet and material outlet of the first conveyor 131 have a height difference. The first conveyor 131 is divided into two sections, one section is horizontally set, and the other section is an inclined section. The material in the horizontal section is transported to the inclined section, and then transported to the higher outlet in an inclined direction, and enters or falls into the second conveyor 132 from the outlet; in an optional embodiment, each first conveyor 131 corresponds to a second conveyor 132, and metallurgical solid waste can enter the second conveyor 132 accordingly. The second conveyor 132 adopts a single screw conveyor, one end of the single screw conveyor is located at the material outlet of the second conveyor 132, and the other end is located at the opening of the material dispersion part 140, so that the material can be transferred from the first conveyor 131 to the material dispersion part 140 for dispersion through the second conveyor 132.
[0041] In an optional embodiment, the inner wall of the aggregate portion 110 is provided with an anti-sticking material layer made of an anti-sticking material, such as a ceramic liner, to prevent the metallurgical solid waste from adhering to the inner wall of the aggregate portion 110 . In an optional embodiment, the aggregation part 110 includes an aggregation bin 111 and a bin cover 112. The aggregation bin 111 is provided with a cavity 111a and an opening connected to the cavity 111a. The opening is located at the top of the aggregation bin 111. The shape and size of the bin cover 112 match the opening of the aggregation part 110, so that the opening can be closed by the bin cover 112. The bin cover 112 is rotatable relative to the aggregation part 110. The edge of the bin cover 112 is hinged to the edge of the opening of the aggregation part 110, and a pivot connection can be adopted, which facilitates the opening and closing of the bin cover 112. The bin cover 112 is used to close the opening of the aggregation bin 111 after the metallurgical solid waste enters the aggregation bin 111. The metallurgical solid waste is sealed in the aggregation part 110 by the bin cover 112, which can prevent the moisture of the steelmaking sludge from being lost too quickly and avoid surface compaction. In an optional embodiment, the bin cover 112 is also provided with a driver, such as a hydraulic driver, which is fixed to the collection bin 111 by screws, and the output rod of the hydraulic driver is hinged to the plate surface of the bin cover 112, so that the bin cover 112 can be driven to rotate by the driver, thereby realizing automatic opening or closing. In an optional embodiment, a material level meter with a sensor is provided in the collection bin 111, which can monitor the material level in the cavity 111a and feedback to the off-site staff to replenish the metallurgical solid waste in time. In order to prevent the steelmaking sludge from being hardened due to long storage time, the storage time in the collection bin 111 should not exceed 8 hours, and the stored material needs to be discharged before the material level meter detects that the material is hardened.
