[0002] The resistance of the sintering machine mixture increases during the process of descending in the silo ore trough, and the contact time between the mixture and the inclined wall of the silo ore trough is relatively prolonged, which aggravates the sticking of the material, especially the upper part of the silo ore trough with a large inclination angle often becomes the most sticky part. Usually, the effective volume of the silo ore trough will decrease by about 30% after three or four days of maintenance. As the sticking situation worsens, it not only fails to increase the storage capacity of the silo ore trough, but also reduces the effective volume of the silo ore trough, reduces the sintering maintenance cycle, and prolongs the maintenance time. Cleaning the silo ore trough is a confined space operation, which poses a great safety risk. At the same time, during the production process, the sticking of the mixture in the silo ore trough will directly affect the uniformity and stability of the sintering material and the quality of the sintered ore.

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 purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

[0027] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "include..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0028] In order to solve the problems of the prior art, the embodiments of the present application provide a silo unloading anti-sticking device and a silo anti-sticking device. The silo unloading anti-sticking device provided in the embodiments of the present application is first introduced below.

[0029] Figure 1 The schematic diagram of the structure of the silo unloading anti-sticking device provided by one embodiment of the present application is shown. Figure 1 As shown, the silo unloading anti-sticking device includes: a silo ore trough 1, a cylindrical structure with a hollow unloading channel 100, and the silo ore trough 1 is gradually arranged from the upper end opening to the lower end discharge port along the unloading channel 100; the silo ore trough 1 is entirely paved with a wear-resistant steel plate 2 along the inner surface of the unloading channel 100; a cleaning device 4, used to prevent the sintered ore mixture from sticking or to clean the sintered ore mixture stuck on the inner surface of the silo ore trough 1.

[0030] The anti-sticking device for silo unloading in the embodiment of the present application can effectively reduce the friction coefficient of the inner surface of the silo ore trough and reduce the friction between the sintered ore mixture and the inner surface of the silo ore trough by laying wear-resistant steel plates on the inner surface of the silo ore trough along the unloading channel; and the silo ore trough is gradually narrowed from the upper end opening to the lower end discharge port along the unloading channel, which can make the sintered ore mixture drop quickly through the unloading channel to avoid the sintered ore mixture from sticking to the inner surface of the silo ore trough; at the same time, the cleaning device can clean the sticky ore on the inner surface of the silo ore trough to further avoid the sticking of the sintered ore mixture on the inner surface of the silo ore trough.

[0031] The silo unloading and anti-sticking device of the embodiment of the present application can effectively improve the problem of sticking of 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 short-term regular 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 unloading channel, so that the sintered ore mixture can fall downward rapidly under the action of its own gravity, preventing the sintered ore mixture from sticking to the inner surface of the silo ore trough and blocking the unloading 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 clear restrictions 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 ore trough 1 can be cylindrical, elliptical, rectangular, triangular, or other polygonal cylindrical structures, so that the sintered ore mixture can be dropped into the mixing silo through the silo ore trough. The present application does not explicitly limit the specific shape of the silo ore trough.

[0033] In some embodiments, the silo ore trough 1 includes a first part 101 and a second part 102, and the second part 102 is connected to the first part 101. The first part 101 is a part with an equal diameter of the material discharge channel, and the second part 102 is a part with a gradually shrinking diameter of the material discharge channel, so that the sintered ore mixture can be discharged normally through the first part 101 with an equal diameter of the material discharge channel, and the second part 102 with a gradually shrinking diameter of the material discharge channel can accelerate the aggregation and fall downward under the gravity of the sintered ore mixture falling from the first part, so as to prevent the sintered ore mixture from sticking to the inner surface of the silo ore trough.

[0034] In some embodiments, 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 between adjacent sides of the silo trough 1 with 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, a wear-resistant steel plate 2 with a grade of NM400QT is welded along the inner surface of the silo ore slot 1 as a whole, and a wear-resistant steel plate 3 in the shape of an arc is welded at four joints (i.e., chamfers) formed along the adjacent edges of the silo ore slot 1, as shown in FIG. Figure 1As shown, the upper and lower inclination angles of the silo ore trough 1 are made consistent as a whole, the sintered ore mixture is discharged more smoothly, the contact time between the sintered ore mixture and the inclined wall of the silo ore trough is shortened, and the sintered ore mixture is prevented from sticking and piling up at the connection between the adjacent sides of the silo ore trough, which hinders the discharge of the silo ore trough and occupies the effective space of the silo ore trough.

[0037] In some embodiments, Figure 1 , Figure 2 and Figure 3 As shown, the cleaning device 4 includes an automatic rapping component 41 which is arranged around the outer peripheral side surface of the silo ore trough 1 and rapps the silo ore trough 1 .

[0038] In some embodiments, the automatic rapping component 41 is arranged along two or more sides of the silo ore slot 1. In an embodiment of the present application, the silo ore slot is automatically rapped regularly by the automatic rapping component, which can prevent sticking and clean up some of the sintered ore mixture that has been bonded. In some optional embodiments, the automatic rapping component is an air cannon. Each air cannon can vibrate and purge regularly at time intervals of 3min, 5min, 10min, 20min, 30min, 45min, and 60min.

[0039] like Figure 1-3 As shown, the self-vibrating components can be relatively arranged on two opposite sides of the outer peripheral side surface of the silo ore trough to remove the sintered ore mixture adhered to the inner surfaces of the two opposite sides of the silo ore trough along the feeding channel. Of course, it can be understood that in order to prevent the sintered ore mixture from adhering to the inner surface of the silo ore trough or to better remove the sintered ore mixture adhered to the inner surface of the silo ore trough, the automatic vibrating components can be arranged on the entire outer peripheral surface of the silo ore trough along the feeding channel, for example, they can be arranged in an array, such as the automatic vibrating components can be evenly distributed in a triangular array or a rectangular array along the feeding channel on the four outer peripheral surfaces of the silo ore trough with a rectangular cross section. Alternatively, the automatic vibrating components are dispersedly arranged around the feeding channel on the outer peripheral surface of the silo ore bin in strip-like intervals, such as at different fixed intervals of 5cm, 10cm, 15cm, 20cm, 25cm, 30cm, 50cm, 80cm, 100cm, 150cm, etc., or are distributed in a spiral shape around the feeding channel on the outer peripheral surface of the silo ore bin, so as to vibrate and remove the sintered ore mixture adhered to the inner surface of the silo ore bin.

[0040] In some embodiments, Figure 2 As shown, the cleaning device 4 includes a rake loosener 42, on which a plurality of rake spikes 420 are arranged, and the rake spikes 420 are tangent to the inner surface of the wear-resistant steel plate 2; the rake loosener 42 can move upward or downward in a direction parallel to the feeding channel to remove the sintered ore mixture adhered to the inner surface of the silo ore slot. It can be understood that the rake loosener 42 can be evenly arranged along the short sides and long sides of the inner surface of the rectangular silo ore slot, Figure 2 Only the rake aerator on one short side is shown.

[0041] In an embodiment of the present application, according to the sintering condition of the mixed material bin of the sintering production line of the steel plant, a cleaning device for removing sticky materials, namely a rake loosener, is installed on the inner surface of the ore trough of the sintered ore mixed material bin. By making the tips of the rake teeth of the rake loosener tangent to the inner surface of the wear-resistant steel plate, the rake loosener can be moved upward or downward in a direction parallel to the discharge channel. The sintered ore mixture adhered to the inner surface of the ore trough of the silo can be vibrated by an automatic vibrating component, and the rake loosener can be used to automatically clean the adhered sintered ore mixture, so that the silo discharge anti-sticking device can operate normally.

[0042] In other embodiments, Figure 2 As shown, the automatic rapping component 41 and the rake aerator 42 can be provided at the same time or separately.

[0043] In some embodiments, Figure 4 As shown, the cleaning device includes a disturbance array plate 43 arranged along the inner surface of the silo ore trough in the material discharge channel; the disturbance array plate 43 includes a plurality of disturbance plates 430 arranged in groups, adjacent disturbance plates 430 are stacked up and down, and the disturbance plates 430 are inclined downward from the inner surface of the silo ore trough 1 to the middle of the material discharge channel 100; one end of the disturbance plate 430 can be rotatably arranged on one side close to the inner surface of the silo ore trough 1, and the other end of the disturbance plate 430 is at least partially overlapped with the adjacent disturbance plate.

[0044] In an embodiment of the present application, the cleaning device covers or coats the inner surface of the wear-resistant steel plate by means of a disturbance array plate arranged in the discharge channel and along the inner surface of the silo ore trough, so that a plurality of disturbance plates are stacked up and down, and inclined downward from the inner surface of the silo ore trough to the middle of the discharge channel, so that the falling sintered ore mixture can fall downward to the middle of the discharge channel, and can be cleared by the disturbance array plate to prevent the sintered ore mixture from sticking to the inner surface of the silo ore trough.

[0045] In one embodiment, if Figure 4 As shown, one end of the disturbance plate 430 is rotatably arranged on one side close to the inner surface of the silo ore trough 1, and the other end of the disturbance plate 430 is at least partially overlapped with the adjacent disturbance plate 430, so that the stacked disturbance plates 430 can be rotated around one end during the process of the sintered ore mixture descending and bonding, or after the sintered ore mixture descends and bonds, and the sintered ore mixture bonded to the stacked and adjacent disturbance plates 430 can be removed by moving the other end upward or downward through the disturbance plate 430.

[0046] For example, Figure 4As shown, the cleaning device 4 includes a disturbance array plate 43 arranged in the material discharge channel 100 and along the inner surface of the silo ore slot 1. The disturbance array plate 43 includes a plurality of disturbance plates 430 arranged in groups. Adjacent disturbance plates 430 are stacked up and down and are arranged to be inclined downward from the inner surface of the silo ore slot 1 to the middle of the material discharge channel 100. Among them, a fixing member 432 is arranged along the material discharge channel 100 on one side close to the inner surface of the silo ore slot 1, and a rotating shaft 431 connected to the fixing member 432 is arranged on the fixing member 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 the sintered ore mixture bonded to the adjacent disturbance plate below it can be removed by pulling the traction rope 433 to make the other end of the disturbance plate 430 move upward or downward.

[0047] In one embodiment, if Figure 6 As shown, in the adjacent disturbance plates 430, the other end of the upper disturbance plate 430 is provided with an inclined surface 430a inclined toward the other end of the disturbance plate 430, that is, the end in contact with the lower disturbance plate 430 is provided with an inclined surface 430a inclined toward the other end, so as to reduce the probability of the sintered ore mixture sticking to the other end of the disturbance plate, so that the sintered ore mixture can be quickly dropped into the mixed material bin. At the same time, the disturbance plate 430 can also remove the sintered ore mixture sticking to the adjacent and lower disturbance plate.

[0048] In the embodiment of the present application, the angle at which the disturbance plate 430 is tilted downward from the inner surface of the silo ore trough 1 to the middle of the material discharge channel 100 is not clearly limited in the present application, and the minimum requirement is that it can achieve the rapid descent of the sintered ore mixture. Among them, the angle α at which the disturbance plate 430 is tilted downward from the inner surface of the silo ore trough 1 to the middle of the material discharge channel 100 needs to satisfy 0<α<90°. For example, α can be 5°, 10°, 15°, 30°, 40°, 45°, 50°, 60°, 72°, 75°, 80°, 85°.

[0049] For example, Figure 4 As shown, before the sintered ore mixture starts to be discharged, the angle α between the disturbance plate 430 and the middle part of the discharge channel 100 can be set to 30° by adjusting the height of the traction rope 433, and then the sintered ore mixture starts to be discharged normally. During or after the discharge, part of the sintered ore mixture will adhere to the upper surface of the disturbance plate 430. At this time, the traction rope 433 can be lifted up by a certain height, and then the traction rope 433 can be lowered downward, so that the other end of the disturbance plate 430 (i.e., the end in contact with the adjacent and lowered disturbance plate) can remove the sintered ore mixture adhered to the upper surface of the adjacent and lowered disturbance plate, so as to reduce the adhesion of the sintered ore mixture.

[0050] In some embodiments, Figure 5 As shown, the cleaning device 4 includes a cleaning roller 44 disposed in the material discharge channel 100 at a second preset distance d2 from the inner surface of the silo ore slot 1. The cleaning rollers 44 are arranged in groups along the inner surface of the silo ore slot 1 in the material discharge channel 100. Bristles 440 having a length equal to or greater than the second preset distance d2 are arranged on the circumferential surface of the cleaning rollers 44. In the embodiment of the present application, the cleaning rollers 44 can also be connected in groups through the fixing member 432 so that the cleaning rollers can rotate so that the bristles on the circumferential surface clean the bonded sintered ore mixture.

[0051] In the embodiment of the present application, the silo unloading anti-sticking device is provided with a rotatable cleaning roller in the unloading channel at a second preset distance from the inner surface of the silo ore slot, and bristles less than or equal to the second preset distance are provided on the circumferential surface of the cleaning roller, so that the cleaning roller rotates and drives the bristles on its circumferential surface to remove the sintered ore mixture adhered to the inner surface of the silo ore slot. The bristles equal to or greater than the second preset distance can make the bristles on the cleaning roller fully contact the sintered ore mixture adhered between the cleaning roller and the inner surface of the silo ore slot, and fully remove it.

[0052] In other embodiments, a cleaning felt may be provided on the circumferential surface of the cleaning roller 44, or a distance less than or equal to the second preset distance d2 may be provided around the cleaning roller 44, so that the cleaning roller can use the cleaning felt to remove the sintered ore mixture adhered to the inner surface of the silo ore tank during rotation.

[0053] In other embodiments, the automatic rapping component 41 and the disturbance array plate 43 may be provided at the same time, or the automatic rapping component 41 and the cleaning roller 44 may be provided at the same time.

[0054] like Figure 3 As shown, in the second aspect, an embodiment of the present application provides a silo anti-sticking device, including the above-mentioned silo unloading anti-sticking device and the material pouring device 5, the material pouring device 5 includes a shuttle transport vehicle 51 and a material baffle plate 52, the material baffle plate 52 is arranged relative to the head wheel 511 of the belt 510 of the shuttle transport vehicle 51 at a first preset distance d1.

[0055] In the embodiment of the present application, the unloading device arranged on the upper part of the silo unloading anti-sticking device suppresses the parabolic trajectory of the sintered ore mixture during unloading by installing a baffle plate of a first preset distance in front of the position of the shuttle transport belt head pulley, so as to ensure that the sintered ore mixture can fall vertically into the mixed material bin, avoid the sintered ore mixture from directly impacting the inner surface of the silo ore trough when falling from the shuttle transport, and reduce the contact probability between the sintered ore mixture and the inclined wall of the ore trough, thereby avoiding the occurrence of the sticking problem. The present application does not make a clear limit on the value of the first preset distance, and it can determine a suitable first preset distance according to the size of the shuttle transport and the silo ore trough, such as 15cm, 20cm, 30cm, 50cm, etc., so that the baffle plate 52 suppresses the parabolic trajectory of the sintered ore mixture transported by the shuttle transport 51 during unloading, and ensures that the sintered ore mixture can fall vertically into the mixed material bin.

[0056] After adopting the above-mentioned transformation measures, the silo unloading anti-sticking device and silo anti-sticking equipment of the present application are obtained, the production stability of the sintering system is improved, the uniformity of the lateral distribution of the sintering machine is improved, and the situation affecting the distribution in front of the furnace is reduced, which solves the difficult problems that must be solved to achieve uniform sintering in the sintering system.

[0057] The silo unloading anti-sticking device and silo anti-sticking equipment of the present application are improved through the above-mentioned improvements, which are measures to improve the sticking of the mixed silo of the sintering machine. The sintering machine can be used for regular repairs in a short time without affecting the normal production of the sintering machine, shortening the time for regular maintenance, reducing the risk of manual operation to clean up sticky materials in a confined space, and extending the maintenance cycle of the silo unloading anti-sticking device and the silo anti-sticking equipment.
