DETAILED DESCRIPTION

[0026] The features and exemplary embodiments of various aspects of the present application will be described in detail below, in order to make the purposes, technical solutions and advantages of the present application more clear and apparent, the present application will be further described in detail below in combination with the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, but not to limit the present application. The present application can be implemented without some of these specific details by those skilled in the art. The following description of the embodiments is only intended to provide a better understanding of the present application by showing examples of the present application.

[0027] It is to be understood that the terminology used herein such as first and second, and the like, is merely intended to differentiate one entity or action from another entity or action, without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element proceeded by "comprises... a" does not, without more constraints, exclude the presence of additional identical elements in the process, method, article, or apparatus that comprises the element.

[0028] To solve the problems in the prior art, the application provides a stock bin discharging anti-sticking device and a stock bin anti-sticking device. First, the stock bin discharging anti-sticking device provided by the application is introduced.

[0029] Figure 1 A structure diagram of the stock bin discharging anti-sticking device provided by an embodiment of the application is shown. As shown in Figure 1 The stock bin discharging anti-sticking device comprises: a stock bin chute 1, which has a hollow discharging channel 100 and a cylindrical structure, and is tapered from an upper end opening to a lower end discharge port along the discharging channel 100; a wear-resistant steel plate 2, which is laid on the inner surface of the stock bin chute 1 along the discharging channel 100; and a cleaning device 4, which is used to prevent the sintered ore mixture from sticking or clean the sintered ore mixture sticking to the inner surface of the stock bin chute 1.

[0030] The stock bin discharging anti-sticking device provided by the application can effectively reduce the friction coefficient of the inner surface of the stock bin chute by laying the wear-resistant steel plate on the inner surface of the stock bin chute along the discharging channel, and reduce the friction between the sintered ore mixture and the inner surface of the stock bin chute. The stock bin chute is tapered from the upper end opening to the lower end discharge port along the discharging channel, which can make the sintered ore mixture quickly descend through the discharging channel and avoid the sintered ore mixture from sticking to the inner surface of the stock bin chute. At the same time, the cleaning device can clean the sticking ore on the inner surface of the stock bin chute, further avoiding the sintered ore mixture from sticking to the inner surface of the stock bin chute.

[0031] The silo unloading and anti-sticking device of the embodiment of the present application can effectively improve the problem of material sticking in the mixed silo of the sintering machine through the above-mentioned improvement measures. The silo unloading and anti-sticking device is easy to modify, quick to take effect, and requires little investment. It can be constructed and modified during the regular short-term maintenance of the sintering machine without affecting the normal production of the sintering machine. It should be noted that the silo ore trough is gradually narrowed from the upper end opening to the lower end discharge port along the discharge channel, so that the sintered ore mixture can fall downward rapidly under the action of its own gravity, preventing the sintered ore mixture from adhering to the inner surface of the silo ore trough and blocking the discharge channel. The upper end opening of the silo ore trough can be set at the top or one side of the silo ore trough, and this application does not make a clear limitation on this. The lower end discharge port of the silo ore trough, that is, the position where the sintered ore mixture leaks out through the silo ore trough, is located at the lower part of the feed port 6.

[0032] In some embodiments of the present application, the cylindrical structure of the silo trough 1 can be cylindrical, elliptical, rectangular, triangular, or other polygonal cylindrical structures, so that the sintered ore mixture can descend into the mixing silo through the silo trough. The present application does not explicitly limit the specific shape of the silo trough.

[0033] In some embodiments, the silo chute 1 includes a first portion 101 and a second portion 102, wherein the second portion 102 is connected to the first portion 101. The first portion 101 is a portion of the silo discharge channel having a uniform diameter, while the second portion 102 is a portion of the silo discharge channel having a gradually decreasing diameter. This allows the sintered ore mixture to be discharged normally through the first portion 101 having a uniform diameter. The second portion 102 having a gradually decreasing diameter allows the sintered ore mixture to accelerate its accumulation and downward fall under the action of gravity from the silo discharge channel, thereby preventing the sintered ore mixture from adhering to the inner surface of the silo chute.

[0034] In some embodiments, as Figure 2 As shown, the cross section of the silo trough 1 perpendicular to the direction Y of the material discharge channel is rectangular.

[0035] In some embodiments, arc-shaped wear-resistant steel plates 3 are provided at the connection points of adjacent sides of the silo hopper 1 having a rectangular cross section.

[0036] In the embodiment of the present application, the wear-resistant steel plate may be a wear-resistant steel plate with a grade of NM400QT, such as Figure 2 As shown, the wear-resistant steel plate 2 with the grade of NM400QT is welded along the inner surface of the silo ore trough 1 as a whole, and the four joints (i.e. chamfers) formed along the adjacent sides of the silo ore trough 1 are welded with arc-shaped wear-resistant steel plates 3, as shown in FIG. Figure 1As shown, the upper and lower inclination angles of the stock bin chute 1 are consistent as a whole, the sintered ore mixture is discharged more smoothly, the contact time of the sintered ore mixture with the inclined wall of the stock bin chute is shortened, and the sintered ore mixture is prevented from sticking and accumulating at the connecting part of adjacent sides of the stock bin chute, thereby preventing the sintered ore mixture from blocking the discharge and occupying the effective space of the stock bin chute.

[0037] In some embodiments, as shown in Figure 1 , Figure 2 and Figure 3 , the cleaning device 4 comprises an automatic rapping component 41 arranged around the outer peripheral side surface of the stock bin chute 1 and rapping the stock bin chute 1.

[0038] In some embodiments, the automatic rapping component 41 is arranged on opposite sides or multiple sides of the stock bin chute 1. In the embodiments of the present application, the stock bin chute is periodically automatically rapped by the automatic rapping component, which can prevent sticking and clean part of the sintered ore mixture that has been stuck. In some optional embodiments, the automatic rapping component is an air cannon. Each air cannon can periodically vibrate and blow at time intervals of 3 min, 5 min, 10 min, 20 min, 30 min, 45 min, 60 min, etc.

[0039] As shown in Figures 1-3 , the automatic rapping components can be oppositely arranged on opposite sides of the outer peripheral side surface of the stock bin chute to clean the sintered ore mixture stuck to the inner surfaces of the opposite sides of the stock bin chute along the discharge passage. Of course, it can be understood that, in order to prevent the sintered ore mixture from sticking to the inner surface of the stock bin chute or better clean the sintered ore mixture stuck to the inner surface of the stock bin chute, the automatic rapping components can be arranged on the entire outer peripheral surface of the stock bin chute along the discharge passage, for example, can be arranged in an array, such as the automatic rapping components can be uniformly distributed in a triangular array or a rectangular array on the four outer peripheral surfaces of the stock bin chute along the discharge passage in a rectangular cross-section. Alternatively, the automatic rapping components are arranged in a strip-shaped interval around the outer peripheral surface of the stock bin chute along the discharge passage, such as arranged at different fixed intervals of 5 cm, 10 cm, 15 cm, 20 cm, 25 cm, 30 cm, 50 cm, 80 cm, 100 cm, 150 cm, etc., or arranged in a spiral along the discharge passage on the outer peripheral surface of the stock bin chute, to vibrate and clean the sintered ore mixture stuck to the inner surface of the stock bin chute.

[0040] In some embodiments, as shown in Figure 2 , the cleaning device 4 comprises a rake loosener 42, and a plurality of rake tines 420 are arranged on the rake loosener 42 and tangent to the inner surface of the wear-resistant steel plate 2; the rake loosener 42 can move upward or downward along a direction parallel to the discharge passage to clean the sintered ore mixture stuck to the inner surface of the stock bin chute. It can be understood that the rake loosener 42 can be uniformly arranged along the short sides and long sides of the inner surface of the stock bin chute in a rectangular cross-section,Figure 2 Only one side of the short side of the rake loosener is shown.

[0041] In the embodiments of the present application, according to the sintering condition of the sintering production line mixing bin of the steelmaking plant, a cleaning device for removing the adhered material is installed on the inner surface of the sinter mixing bin, i.e., a rake loosener. The rake loosener can move upward or downward along the direction parallel to the discharge passage by tangentially connecting the tip of the rake pin tooth of the rake loosener to the inner surface of the wear-resistant steel plate. Then, the adhered sinter mixing material on the inner surface of the bin can be removed by the automatic vibrating component and the rake loosener, so that the discharge anti-adhesion device of the bin can operate normally.

[0042] In other embodiments, as shown in Figure 2 , the automatic vibrating component 41 and the rake loosener 42 can be provided simultaneously or separately.

[0043] In some embodiments, as shown in Figure 4 , the cleaning device includes a disturbance array plate 43 provided along the inner surface of the bin sump in the discharge passage. The disturbance array plate 43 includes a plurality of disturbance plates 430 arranged in groups. Adjacent disturbance plates 430 are arranged in a stacked manner, and the disturbance plates 430 are inclined downward from the inner surface of the bin sump 1 to the middle of the discharge passage 100. One end of the disturbance plate 430 is rotatably arranged on one side close to the inner surface of the bin sump 1, and the other end of the disturbance plate 430 is at least partially overlapped with the adjacent disturbance plate.

[0044] In the embodiments of the present application, the cleaning device covers the inner surface of the wear-resistant steel plate by providing a disturbance array plate along the inner surface of the bin sump in the discharge passage. The plurality of disturbance plates are arranged in a stacked manner and inclined downward from the inner surface of the bin sump to the middle of the discharge passage, so that the falling sinter mixing material can fall downward to the middle of the discharge passage, and the sinter mixing material can be removed by the disturbance array plate to prevent the sinter mixing material from adhering to the inner surface of the bin sump.

[0045] In an embodiment, as shown in Figure 4 , one end of the disturbance plate 430 is rotatably arranged on one side close to the inner surface of the bin sump 1, and the other end of the disturbance plate 430 is at least partially overlapped with the adjacent disturbance plate 430. This allows the stacked disturbance plates 430 to remove the sinter mixing material adhered to the stacked and adjacent disturbance plates 430 by rotating the disturbance plate 430 around one end and moving the other end upward or downward during or after the sinter mixing material is adhered.

[0046] Exemplarily, as shown in Figure 4 , the cleaning device includes a disturbance array plate 43 provided along the inner surface of the bin sump in the discharge passage. The disturbance array plate 43 includes a plurality of disturbance plates 430 arranged in groups. Adjacent disturbance plates 430 are arranged in a stacked manner, and the disturbance plates 430 are inclined downward from the inner surface of the bin sump 1 to the middle of the discharge passage 100. One end of the disturbance plate 430 is rotatably arranged on one side close to the inner surface of the bin sump 1, and the other end of the disturbance plate 430 is at least partially overlapped with the adjacent disturbance plate.As shown, the cleaning device 4 comprises a disturbance array plate 43 arranged in the discharging channel 100 along the inner surface of the bunker chute 1, the disturbance array plate 43 comprises a plurality of disturbance plates 430 arranged in groups, the adjacent disturbance plates 430 are arranged in a stack from top to bottom, and are arranged to be inclined downward from the inner surface of the bunker chute 1 to the middle of the discharging channel 100. Among them, a fixed part 432 is arranged along the discharging channel 100 on the side close to the inner surface of the bunker chute 1, and a rotating shaft 431 connected with the fixed part 432 is arranged on the fixed part 432. One end of the disturbance plate 430 is arranged on the rotating shaft 431 through a connecting hole, and the other end of the disturbance plate 430 is at least partially overlapped with the adjacent disturbance plate 430, so that by pulling the traction rope 433, the other end of the disturbance plate 430 will remove the sinter mixture adhered to the lower adjacent disturbance plate during the upward or downward movement.

[0047] In an embodiment, as shown in Figure 6 Among the adjacent disturbance plates 430, the other end of the upper disturbance plate 430 is arranged to be inclined to the other end of the disturbance plate 430, that is, the end in contact with the lower disturbance plate 430 is arranged to be inclined to the other end, so as to reduce the probability of sinter mixture adhering to the other end of the disturbance plate, thereby enabling the sinter mixture to quickly descend into the mixing bunker. At the same time, it also enables the disturbance plate 430 to remove the sinter mixture adhered to the adjacent lower disturbance plate.

[0048] In the embodiment of the present application, the angle at which the disturbance plate 430 is arranged to be inclined downward from the inner surface of the bunker chute 1 to the middle of the discharging channel 100 is not specifically limited in the present application, and the minimum requirement is that it can enable the sinter mixture to quickly descend. Among them, the angle α at which the disturbance plate 430 is arranged to be inclined downward from the inner surface of the bunker chute 1 to the middle of the discharging channel 100 needs to satisfy 0 < α < 90°. Exemplarily, α can be 5°, 10°, 15°, 30°, 40°, 45°, 50°, 60°, 72°, 75°, 80°, 85°.

[0049] Exemplarily, as shown in Figure 4 Before the sinter mixture starts to be discharged, by adjusting the height of the traction rope 433, the included angle α at which the disturbance plate 430 is arranged to be inclined in the middle of the discharging channel 100 can be set to 30°, and then the sinter mixture is started to be normally discharged. During or after the discharging process, part of the sinter mixture will adhere to the upper surface of the disturbance plate 430. At this time, the traction rope 433 can be first lifted by a certain height, and then the traction rope 433 is lowered, so that the other end of the disturbance plate 430 (that is, the end in contact with the adjacent lower disturbance plate) removes the sinter mixture adhered to the upper surface of the adjacent lower disturbance plate, so as to reduce the adhesion of the sinter mixture.
