Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of sintering machines, and in particular relates to a material loosening device and a sintering machine with the same. BACKGROUND

[0002] The sintering process is the most widely used raw material agglomeration method in steel enterprises. At present, almost all sintering machines used in various sintering plants are downdraught belt sintering machines. Sintering is a process in which dried iron-containing raw materials, fuel and flux are proportioned and then mixed and granulated to form granular mixtures. The granular mixtures are uniformly distributed on the sintering trolley of the sintering machine by a circular roller distributor, and the mixtures are sintered into sinter by the downdraught sintering machine. In order to ensure the quality and yield of the sinter, the mixture layer on the sintering trolley should have good permeability. Therefore, a material loosening device is needed to increase the permeability of the mixture layer during distribution.

[0003] In the related art, the material loosening device is composed of a rectangular frame and a crossbar. During the loosening process, the movement speed of the mixture slows down, and even stops for a short time. The mixture quickly accumulates and bonds on the frame and the crossbar, forming irregularly distributed and irregularly sized "holes" in the mixture layer, resulting in uneven permeability of the mixture layer and uneven sintering process, which affects the yield of the sinter. To clean the accumulated material on the material loosening device, the sintering machine needs to be stopped and the distribution on the sintering machine needs to be stopped. Then, a long rod is used to clean the accumulated material manually. Each time the accumulated material is cleaned, it takes a long time, which affects the continuity of the sintering production.

[0023] In order to make the purpose, technical scheme and advantages of the present application more clear, the following will make further detailed description to the embodiments of the present application in combination with the drawings.

[0024] In addition, in the description of the present application, the orientation or position relationship indicated by the terms “longitudinal”, “transverse”, “upper”, “lower”, “front”, “rear”, “left”, “right”, “vertical”, “horizontal”, “top”, “bottom” and the like is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the present application and does not require the present application to be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation to the present application. The terms “connected” and “connected” used in the present application should be understood broadly, for example, it can be fixed connection, or can be detachable connection; can be directly connected, or indirectly connected through intermediate components, for those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0025] In related technologies, the thickness of the uniformly distributed material layer on the sintering trolley of the sintering machine can be controlled between 900mm and 920mm according to actual production needs. The mixture is then sintered by the sintering machine through ventilation to form sintered ore. During this process, a fixed feeder is used to maintain good air permeability of the material layer. However, this fixed feeder consists of a rectangular frame and a crossbar. During the loosening process, material accumulation occurs 2-3 times per shift at the crossbar position, hindering the normal feeding of the feeder and resulting in uneven material layer thickness. During sintering, the material layer collapses, forming voids, which negatively impacts the yield of the sintered ore. For these reasons, to clean the accumulated material on the feeder, the sintering machine needs to be shut down and feeding stopped, and the accumulated material needs to be manually cleaned with a long pole. Each cleaning takes about 15 minutes, severely affecting the continuity and efficiency of sintering production.

[0026] The first aspect of the present invention aims to solve the problems existing in the above-mentioned related technologies and provide a material loosening device to ensure the continuous operation of the sintering machine. Figure 1 This is a front view schematic diagram of an embodiment of the loosening device of the present invention; Figure 2 This invention relates to a loosening device. Figure 1 The diagram shows a top view of the embodiment. Figure 3 This invention relates to a loosening device. Figure 1 A side view of the embodiment shown is a schematic diagram. Figure 4 This is a schematic diagram of the assembly structure of the main limiting member and the positioning member of another embodiment of the material loosening device of the present invention. Figures 1 to 4 As shown, the loosening device may include a first support beam 1, a second support beam 2, a rotating shaft 3, a stop 4, a rocker arm 5, and a limiting member 6. The first support beam 1 may have multiple first fixing rings 11 spaced apart. The second support beam 2 may be parallel to the first support beam 1 and may have multiple second fixing rings 21, each corresponding to a first fixing ring 11 on the same central axis. The rotating shaft 3 may pass through the first fixing rings 11 and the second fixing rings 21. The first end of the rotating shaft 3 may have a stop 4, and the second end may have a rocker arm 5. The first fixing rings 11 and 21 may be positioned between the stop 4 and the rocker arm 5. The limiting member 6 may have a limiting frame 61 corresponding to the number and position of the rocker arm 5. The size of the limiting frame 61 may be larger than the cross-sectional size of the rocker arm 5, and the limiting member 6 may be movably connected to a positioning member 7 to restrict the swing of the rocker arm 5.

[0027] In this embodiment, the first support beam 1 and the second support beam 2 can be made of flat steel. The flat steel has high hardness and is not easy to deform. Using flat steel to fix can enhance the stability of the structure and ensure the stability of the operation. In one example, the thickness of the flat steel used can be 5 mm, the length of the flat steel can be 4000 mm, and the width of the flat steel can be 50 mm. The manufacturing material of the first support beam 1 and the second support beam 2 can also be other types, and the shape and size of the first support beam 1 and the second support beam 2 can also be adjusted according to actual production needs, which are not limited in this embodiment.

[0028] The first support beam 1 and the second support beam 2 are arranged in parallel, and a plurality of first fixing rings 11 can be arranged at intervals on the first support beam 1, and a plurality of second fixing rings 21 can be arranged at intervals on the second support beam 2. The length of the first support beam 1 and the second support beam 2 can be equal, and the number of the first fixing rings 11 fixed on the first support beam 1 can also be equal to the number of the second fixing rings 21 fixed on the second support beam 2. Moreover, the first fixing ring 11 and the second fixing ring 21 can be the same ring structure, the first fixing ring 11 and the second fixing ring 21 can correspond one by one in position, and the first fixing ring 11 and the corresponding second fixing ring 21 on the second support beam 2 can coincide with the center axis, that is, the same center axis.

[0029] The rotating shaft 3 can be made of round steel with a diameter of 20 mm, and the length of the rotating shaft 3 can be 5000 mm. Each rotating shaft 3 is provided with two ends, i.e. a first end and a second end, along the length direction thereof. Each group of first fixing ring 11 and second fixing ring 21 with the same center axis is respectively sleeved between the first end and the second end of the rotating shaft 3, wherein the first end is close to the first fixing ring 11, and the second end is close to the second fixing ring 21. Through the above design, the rotating shaft 3 can rotate around the above-mentioned center axis. Compared with the fixed rectangular frame and cross bar in the prior art, the loose material device of the present embodiment is a movable structure, which is more convenient for cleaning accumulated material during sintering operation, and can clean the accumulated material without stopping the material, thereby ensuring the continuity of the material.

[0030] In one example, a plurality of first fixing rings 11 can be connected to the first support beam 1 at equal intervals along the length direction of the first support beam 1, and a plurality of second fixing rings 21 can be connected to the second support beam 2 at equal intervals along the length direction of the second support beam 2. The way in which the plurality of first fixing rings 11 are connected to the first support beam 1 respectively, and the way in which the plurality of second fixing rings 21 are connected to the second support beam 2 respectively, can be welding or one-piece forming, or other ways such as screw connection, buckle connection and other ways that can be thought of by those skilled in the art, which are not enumerated one by one in this embodiment.

[0031] To ensure that the rotating shaft 3 does not fall off the one-to-one corresponding first fixed ring 11 and the second fixed ring 21, a stop piece 4 can be provided at the first end of the rotating shaft 3, and a rocker 5 can be provided at the second end of the rotating shaft 3. The stop piece 4 and the rocker 5 can respectively protrude the rotating shaft 3 along the diameter direction of the rotating shaft 3, so that the first fixed ring 11 and the second fixed ring 21 are located between the stop piece 4 and the rocker 5, thereby limiting the relative movement of the rotating shaft 3 along its length direction with the first fixed ring 11 and the second fixed ring 21 to separate from the first fixed ring 11 and the second fixed ring 21, and ensuring the structural stability of the material loosening device of the embodiment.

[0032] In some embodiments, the stop piece 4 and / or the rocker 5 are welded to the rotating shaft 3, or the stop piece 4 and / or the rocker 5 are detachably connected to the rotating shaft 3. That is, there are various combinations of connection methods. The stop piece 4 and the rocker 5 are respectively welded to the first end and the second end of the rotating shaft 3; the stop piece 4 and the rocker 5 are respectively detachably connected to the first end and the second end of the rotating shaft 3; the stop piece 4 is welded to the first end of the rotating shaft 3, and the rocker 5 is detachably connected to the second end of the rotating shaft; the stop piece 4 is detachably connected to the first end of the rotating shaft 3, and the rocker 5 is welded to the second end of the rotating shaft; the stop piece 4 or the rocker 5 is integrally formed with the rotating shaft 3. Among them, the stop piece 4 can be a stop block or an annular boss protruding the rotating shaft 3 along the diameter direction of the rotating shaft 3, and the stop piece 4 is detachably connected or welded to the rotating shaft 3. In one implementation, a threaded hole or a threaded groove can be formed in the first end of the rotating shaft 3 along the diameter direction of the rotating shaft 3, and a threaded rod is provided on the stop piece 4, and the stop piece 4 is detachably connected to the first end of the rotating shaft 3 through the cooperation of the threaded rod and the threaded hole or the threaded groove. In another implementation, the stop piece 4 can be welded to the first end of the rotating shaft 3. The above implementation is only an exemplary description of the connection method and position of the stop piece 4 and the rotating shaft 3. Of course, other connection methods can also be thought of by those skilled in the art, which are not listed one by one in this embodiment, but do not affect the understanding of the scheme by those skilled in the art.

[0033] Similarly, the rocker 5 can be connected to the second end of the rotating shaft 3, and the rocker 5 can cooperate with the stop piece 4 to limit the rotating shaft 3 between the first fixed ring 11 and the second fixed ring 21. In addition, the rocker 5 can be made of a 20mm diameter round steel, and the length thereof can be about 2000mm. The rocker 5 can be perpendicular to the rotating shaft 3, or can be at any angle with the rotating shaft for convenient operation, such as 90 degrees, 60 degrees, 150 degrees, etc. The above angles are only exemplary descriptions, and are not a limitation on the material and shape of the rocker 5 and the angle with the rotating shaft 3.

[0034] In the embodiment, the rocker 5 can not only limit the rotation shaft 3 on the first fixed ring 11 and the second fixed ring 21 in cooperation with the stopper 4, but also can realize the reciprocating rotation of the rotation shaft 3 within a certain angle range by swinging the rocker 5 by the operator, thereby reducing the working strength of the operator and the operation complexity of directly rotating the above rotation shaft 3.

[0035] The limiting piece 6 can be a hard plate, and the limiting frame 61 can be a long hole penetrating the limiting piece 6. The length direction of the limiting frame 61 is the swinging direction of the rocker 5. In the embodiment, a fixed flange can be arranged at the long side of the hard plate of the limiting piece 6, thereby fixing the limiting piece above the second end of the rotation shaft 3. The rocker 5 penetrates the limiting frame 61, and the swinging amplitude of the rocker 5 is limited by the limiting frame 61. In an implementation, when the accumulated material does not need to be cleaned, the rocker 5 can be perpendicular to the plate surface of the hard plate of the limiting piece 6, and the rocker 5 penetrates the center of the limiting frame 61, so that the swinging amplitude of the rocker 5 is the same, which facilitates the operator to hold the rocker 5 to swing in the limiting frame 61 and drive the rotation shaft 3 to rotate, thereby cleaning the accumulated material. The limiting frame 61 limits the maximum angle of the rotation of the rocker 5, thereby limiting the maximum angle of the rotation of the rotation shaft. In the embodiment, the limiting frame 61 can be a rectangular hole or a long circular hole, etc. which is not enumerated one by one in the embodiment. The width of the limiting frame 61 is greater than or equal to the diameter of the rocker 5.

[0036] During the reciprocating rotation of the operator holding the rocker 5, the rocker 5 can also knock the limiting piece 6 at the edge of the limiting frame 61, thereby causing the rocker 5 to vibrate. The vibration can be transmitted to the rotation shaft 3, so that the rotation shaft 3 can not only be cleaned by rotation, but also be cleaned by vibration during the cleaning of the accumulated material, thereby further improving the thoroughness of the cleaning of the accumulated material.

[0037] In some embodiments, in order to ensure that the rocker 5 can remain stationary when the accumulated material is not cleaned, a positioning piece 7 can also be arranged at the position close to the limiting frame 61 of the limiting piece 6. The positioning piece 7 can be a U-shaped frame. The bottom shaft of the U-shaped frame is connected to the limiting piece 6, and the connection position is on the midline of the length of the limiting frame 61. The width of the U-shaped frame is equal to the diameter of the rocker 5. When the U-shaped frame clamps the rocker 5, the rocker 5 is placed at the center of the length direction of the limiting frame 61. When the rocker 5 needs to be swung to clean the accumulated material, the positioning piece 7 is flipped to release the limitation of the rocker 5, and then the rocker 5 is swung to clean the accumulated material.

[0038] In some embodiments, the part of the rotation shaft 3 between the first fixed ring 11 and the second fixed ring 21 is provided with two swing pieces 31. The two swing pieces 31 are connected to the rotation shaft 3 along the length direction of the rotation shaft 3 at both ends of the diameter of the rotation shaft 3. In an example, the swing piece 31 is a hard plate, and the rocker 5 is perpendicular to the long side of the swing piece 31 along the length direction of the rotation shaft 3.

[0039] The swing plate 31 is fixed to the rotating shaft 3, occupying a portion of the outer surface area of ​​the rotating shaft 3. Therefore, the swing plate 31 reduces the contact area between the outer surface of the rotating shaft 3 and the mixture, effectively reducing the impact of the rotating shaft 3 on the fabric mixture, improving fabric uniformity and loosening effect, and thus reducing the frequency of material accumulation cleaning, decreasing the number of times the material loosener accumulates per shift to 1-2 times. In addition, the swing plate 31 acts as a counterweight for the rotating shaft 3, and the vibration generated by the swinging of the rocker arm 5 and its contact with the limiting component 6 further facilitates the cleaning of accumulated material on the rotating shaft 3.

[0040] Based on the same or similar design concept, a second aspect of the present invention provides a sintering machine, which includes a circular roller feeder and an iron frame placed below the circular roller feeder. The iron frame is fixed with a material loosening device as described in any of the first aspect and the preferred embodiments above. The first support beam 1, the second support beam 2 and the limiting member 6 of the material loosening device are respectively fixed to the iron frame.

[0041] In this embodiment, a first support beam 1 and a second support beam 2, each 4000mm long and 50mm wide, can be made from 5mm thick flat steel; nine rotating shafts 3, each 5000mm long, and nine rocker arms 5, each 2000mm long, can be made from 20mm diameter round steel; nine first fixing rings 11, each 50mm long, and nine second fixing rings 21, each 50mm long, can be made from 25mm diameter steel pipe; nine limiting iron plates, each 100mm long and 50mm wide, can be made from 3mm thick steel plates as limiting components 6 and welded to the first end of the rotating shaft 3; and 18 rocker arms 5, each 5000mm long, can be made from 3mm thick steel plates. A 4500mm long and 20mm wide swing plate 31; a 4500mm long and 200mm wide limiting member 6 can be made of a 3mm thick steel plate, the limiting member 6 having a limiting frame 61 corresponding to the 9 rocker arms 5, the position interval between the limiting frames 61 being 50mm, the limiting frame 61 being formed by cutting the steel plate of the limiting member 6, and having a rectangular hole with a length of 200mm and a width of 50mm; an iron U-shaped limiting pin can be rotatably connected to the limiting member 6 near each limiting frame 61, the width of the U-shaped limiting pin being 25mm, the U-shaped limiting pin being able to rotate in the vertical direction to position the rocker arm 5;

[0042] Nine first fixing rings 11 can be welded at equal intervals on the first support beam 1, and nine second fixing rings 21 can be welded at equal intervals on the second support beam 2. The first support beam 1 and the second support beam 2 are welded parallel to each other on the iron frame below the sintering machine's roller feeder, with the first fixing rings 11 positioned below the first support beam 1 and the second fixing rings 21 positioned below the second support beam 2. Two swing plates 31 are welded and fixed along the center line of the rotation shaft 3 to both ends of the diameter of the rotation shaft 3, and are welded sequentially on the aforementioned nine rotation shafts 3; one end of each of the nine welded rotation shafts 3 is inserted into the first fixing ring 11 of the first support beam 1; one limiting member 4 is welded and fixed on the center line of the rotation shaft 3 outside the first fixing ring 11 on the first support beam 1, and nine such members are welded sequentially.

[0043] Insert the second ends of the nine welded rotating shafts 3 into the second fixing rings 21 on the second support beam 2. Weld the second support beam 2 to the iron frame of the fabric platform, ensuring that the second support beam 2 and the first support beam 1 are on the same horizontal plane. Weld the rocker arm 5 to the second end of the rotating shaft 3, with the welding position on the outside of the second support beam 2. Ensure that the rocker arm 5 is perpendicular to the swing plate 31, and weld the nine shafts in sequence.

[0044] The limiting component 6 is placed at the middle position of the length of the rocker arm 5 and welded to the fabric platform. After material accumulation, the worker only needs to shake the rocker arm 5 back and forth to hit the limiting component 6 on the edge of the limiting frame 61, so that the rotating shaft 3 rotates and vibrates, thereby clearing the accumulated material.

[0045] In this embodiment of the sintering machine, two swing plates 31 are welded to the center lines at both ends of the diameter of the rotating shaft 3 to reduce the contact area between the rotating shaft 3 and the mixture. Simultaneously, the presence of the swing plates 31 reduces the impact of the rotating shaft 3 on the material distribution, improving the uniformity of material distribution and the loosening effect. Multiple first fixing rings 11 and second fixing rings 21 are welded to the first support beam 1 and the second support beam 2, respectively. The first and second ends of the rotating shaft 3 are respectively fitted with the first fixing rings 11 and the second fixing rings, and the rotating shaft 3 is limited by the stop 4 and the rocker arm 5, thus allowing the rotating shaft 3 to rotate. A limiting member 6 is installed on the rocker arm 5. During the cleaning process, the rocker arm 5 impacts the limiting member 6, causing the rotating shaft 3 to vibrate. Under the action of the rotation and vibration of the rotating shaft 3, the accumulated material is thoroughly cleaned, improving the cleaning efficiency.

[0046] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its essence or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or its equivalents are included in this invention.
