Description

[0001] This patent claims the priority of the patent with the title "A Discharging Device for a Sintering Machine System" and application number 2024214383874, filed on June 21, 2024. Technical Field

[0002] The utility model relates to the technical field of sintering equipment, and specifically, to a discharging device for a sintering machine system. Background Art

[0003] In the metallurgical industry, sintered ore is an important raw material for ironmaking. The efficiency and stability of its production process are crucial for the smooth operation of the entire production line. The sintering machine system, as the core equipment for sintered ore production, plays a pivotal role. And in the sintering machine system, the trolley is an indispensable component.

[0004] During the sintering production process, the trolley is mainly responsible for forming an operating rotary chain between the head and tail wheels of the sintering machine system. However, the failure frequency of the trolley is relatively high. Once the trolley fails, it must be replaced in a timely manner to ensure the continuity and stability of the production line.

[0005] During the process of replacing a faulty trolley, a prominent problem emerges: how to handle the sintered ore on the faulty trolley. Traditionally, enterprises often adopt the method of manual cleaning, but this method is not only time-consuming and laborious but also has relatively high safety risks. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a discharging device for a sintering machine system. By equipping the discharging device in the sintering machine system to discharge the trolley, it replaces the traditional discharging method, significantly reducing production costs and safety risks.

[0007] To achieve the above purpose, the utility model provides a discharging device for a sintering machine system for discharging the trolley, including a driving member and a flipping seat. One end of the flipping seat is used for forming a rotational connection with the tail bracket of the sintering machine system, and the driving member is used to drive the flipping seat to switch between an initial position and a discharging position; the flipping seat is provided with two limiting structures that match the wheels on the corresponding side, and the trolley is accommodated between the two limiting structures. The limiting structure has a stop wall, and the stop wall is used to abut against the wheel wall of the corresponding side wheel to stop the trolley when the flipping seat rotates towards the discharging position.

[0008] Discharging the trolley through the discharging device can replace the traditional discharging method, significantly reducing production costs and safety risks; at the same time, setting the discharging device on the original tail bracket of the sintering machine system avoids adding additional support equipment and increases the integration of the sintering machine system.

[0009] Optionally, each of the limiting structures further includes a guide rail adapted to the wheel, the guide rail being adapted to the wheel, and the stop wall being disposed at one end of the guide rail; by providing a guide rail adapted to the wheel, the trolley is guided to ensure that the trolley can move along the guide rail to a position where it abuts against the stop wall.

[0010] Optionally, each of the limiting structures further includes a stop beam directly or indirectly connected to the tipping seat, the stop beam being opposite to the guide rail in the height direction of the trolley, and the stop beam being capable of abutting against the wheel wall of the wheel away from the guide rail; thereby, the trolley can be stopped, increasing the safety and stability of the operation of the unloading device.

[0011] Optionally, at the initial station, the surface of the stop beam for abutting against the wheel is spaced apart from the wheel; thereby, not only the safety and stability of the unloading device at the unloading station can be improved, but also the trolley can be further tipped relative to the tipping seat with the stop wall as a support.

[0012] Optionally, in the height direction of the trolley, the stop wall is supported between the stop beam and the guide rail; in this way, at the tipping station, the position where the wheel abuts against the stop wall forms a fulcrum for the further tipping of the trolley relative to the tipping seat.

[0013] Optionally, each of the guide rails extends along the length direction of the trolley, and in the extending direction of the guide rail, one end of the guide rail extends beyond the stop beam, so that a section of the guide rail extending beyond the stop beam can contact the wheel of the trolley prior to the stop beam, thereby performing the functions of positioning and guiding the trolley.

[0014] Optionally, the wall surface of the stop wall abutting against the wheel is an arc wall surface, and the arc wall surface fits with the circular wheel wall of the wheel, thereby increasing the contact area between the stop wall and the wheel.

[0015] Optionally, the unloading device further includes a tipping limit member for limiting the extreme position of the tipping seat at the unloading station; by providing a tipping limit member to limit the maximum tipping angle of the tipping seat, it is avoided that at the extreme position of the tipping station, the tipping seat cannot stop and impacts the driving member.

[0016] Optionally, the tipping limit member is a wire rope member, one end of the wire rope member is fixedly connected to the tail bracket, and the other end is fixedly connected to the tipping seat. When the tipping seat is in the extreme position, the wire rope member is in a taut state. By using the wire rope member for limiting, the structure of the tipping limit member can be simplified, and major modifications to the structure of the tail bracket can be avoided.

[0017] Optionally, the discharging device includes a reset limiting member fixedly provided on the tail bracket. At the initial working station, the turning seat presses against the reset limiting member. Thus, at the initial working station, the reset limiting member can support the turning seat at a set height. Description of the Drawings

[0031] In order to enable those skilled in the art of this technology to better understand the solution of the present utility model, the present utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0032] Please refer to Figures 1 to 5 , Figure 1 is a schematic structural view of the discharging device 1 in an embodiment of the present utility model; Figure 2 is Figure 1 an axonometric view ofFigure 3 is an enlarged schematic diagram of the limiting structure; Figure 4 is a schematic diagram of the unloading device 1 in the initial position; Figure 5 It is a schematic diagram of the unloading device 1 in the turning position.

[0033] The utility model provides a discharge device 1 for a sintering machine system. By equipping the sintering machine system with the discharge device 1 of the present application to discharge a faulty trolley 5, the traditional discharge method is replaced, thereby significantly reducing production costs and safety risks.

[0034] The length direction of the trolley in this article refers to the dimension of the trolley along the running direction of the rotary chain 3 of the sintering machine system (usually the horizontal direction); the width direction of the trolley refers to the dimension of the trolley perpendicular to the running direction of the rotary chain 3, that is, the width of the front of the trolley; the height direction of the trolley usually refers to the vertical distance from the bottom of the trolley to the highest point on the top.

[0035] like Figures 1 - 3 As shown, the utility model provides a discharge device 1 for a sintering machine system, and the discharge device 1 is used for performing a discharge operation on a trolley; the discharge device 1 comprises a driving member 18 and a turning seat 17, one end of the turning seat 17 is used to form a rotation connection with the tail bracket 4 of the sintering machine system, and the driving member 18 is used to drive the turning seat 17 to switch between the initial position and the discharge position; the driving member 18 is transmission-connected with the turning seat 17 to drive the turning seat 17 to turn along its rotation axis; wherein the driving member 18 can be a cylinder or a hydraulic cylinder, the driving member 18 comprises a cylinder body and a telescopic rod, the cylinder body is rotationally connected to the tail bracket 4, and the telescopic rod is rotationally connected to the turning seat 17; when the telescopic rod extends out of the cylinder body, the turning seat 17 can be turned outward to make the turning seat 17 rotate to form a certain inclination angle with the horizontal direction to the discharge position, so that the material slides from the trolley under the action of its own gravity; when the telescopic rod is retracted to the cylinder body, the turning seat 17 is pulled back to the initial position for subsequent operation. Among them, the way in which the turning seat 17 and the tail bracket 4 form a rotational connection can be through a rotating shaft and a roller bearing, a sliding bearing, or directly connected by a pin shaft. Technical personnel in this field can choose according to actual needs; in the utility model, the tail bracket 4 refers to a supporting component for supporting the tail wheel of the sintering machine system, and the tail bracket 4 can also adjust the horizontal running length of the rotary chain 3; through this embodiment, the unloading device 1 is arranged on the original tail bracket 4 of the sintering machine system, avoiding the addition of additional supporting equipment for the unloading device 1, thereby increasing the integration of the sintering machine system.

[0036] The tipping seat 17 is provided with two limiting structures for matching with the wheels 51 on the corresponding side. The two limiting structures are symmetrically arranged along the width direction of the trolley. The space between the two limiting structures is used to accommodate the trolley. The limiting structure has a stop wall 12, and the stop wall 12 is perpendicular to the tipping seat 17. The stop wall 12 is used to abut against the wheel wall of the wheel 51 on the corresponding side to stop the trolley when the tipping seat 17 rotates towards the discharging station. In the length direction of the trolley, the wheel set closer to the rotary chain 3 is defined as the front side wheel set, and the two wheels 51 included in the front side wheel set are the front wheels. The stop wall 12 is also arranged on the side of the tipping seat close to the rotary chain 3 and can abut against the front side of the front wheel, so as to stop the trolley when the tipping seat flips, to prevent the trolley from moving. Specifically, the wall surface of the stop wall 12 abutting against the wheel 51 can be a straight wall surface or an arc wall surface 121. The arc wall surface 121 fits with the circular wheel wall of the wheel 51, thereby increasing the contact area between the stop wall 12 and the wheel 51.

[0037] In an optional embodiment, each limiting structure further includes a guide rail adapted to the wheel 51. The guide rail extends along the length direction of the trolley. The two guide rails are arranged opposite to each other in the width direction of the trolley. The guide rail is fixedly connected to the tipping seat 17. Each guide rail specifically includes a rail body 11 and connecting wing plates 122 connected to both sides of the rail body 11. The connecting wing plates 122 are fixedly connected to the upper surface of the tipping seat 17 (the surface away from the tail bracket 4 in the vertical direction) by welding or threaded connection or other means. The end of the rail body 11 close to the rotary chain 3 is provided with the aforementioned stop wall 12. When the trolley is placed on the tipping seat 17, the wheel 51 contacts the rail body 11 and can roll along the rail body 11 to a position where it can abut against the stop wall 12. In this embodiment, by providing a guide rail adapted to the wheel 51, it plays a guiding role for the trolley to ensure that the trolley moves along the guide rail to a position where it abuts against the stop wall 12.

[0038] In the above-described embodiments, each limiting structure further includes a stop beam 13 directly or indirectly connected to the flipping seat 17. The stop beam 13 extends along the length direction of the trolley. The stop beam 13 faces the guide rail in the height direction of the trolley. The stop beam 13 can abut against the wheel wall of the wheel 51 away from the guide rail. That is to say, the vertical space between the stop beam 13 and the rail body 11 in the height direction is used to accommodate the wheel 51. The stop beam 13 and the rail body 11 can respectively abut against both sides of the wheel 51 in the radial direction of the wheel 51. By adopting such a method, the trolley can be stopped, and the safety and stability of the operation of the discharging device 1 can be increased. Here, the stop beam 13 can always abut against the wheel wall of the wheel 51 on the side away from the rail body 11. Or when the discharging device 1 is in the initial position, there is a certain gap between the stop beam 13 and the wheel wall of the wheel 51 on the side away from the rail body 11. When the flipping seat 17 moves to the discharging position, the stop beam 13 abuts against the wheel wall of the wheel 51 on the side away from the rail body 11. That is to say, the surface of the stop beam 13 used to abut against the wheel 51 is spaced from the wheel 51 in the initial position, and the distance between the stop beam 13 and the guide rail is greater than the radial dimension of the part of the wheel 51 adapted to the guide rail. Thus, not only can the safety and stability of the discharging device 1 in the discharging position be improved, but also in this way, the trolley can form a further flip with the stop wall 12 as the support relative to the flipping seat 17. In a specific embodiment, the top end of the stop wall 12 abuts against the stop beam 13, and the bottom end is fixedly connected to the rail body 11. In this way, in the flipping position, the wheel 51 abuts against the stop wall 12 and forms a fulcrum for the further flipping of the trolley relative to the flipping seat 17.

[0039] In the above-described embodiments, in the extending direction of the guide rail, the end of the guide rail away from the rotary chain 3 extends beyond the stop beam 13, which can avoid the interference of the stop beam 13 with the trolley when the trolley just comes into contact with the guide rail.

[0040] The connection mode between the stop beam 13 and the flipping seat 17 can be that each limiting structure includes several connecting plate members 14. One end of the connecting plate member 14 is connected to the stop beam 13, and the other end is connected to the flipping seat 17 and / or the guide rail to support the stop beam 13 above the guide rail. The several connecting plate members 14 are arranged at intervals along the length direction of the trolley.

[0041] In some embodiments of the present application, the discharging device 1 further includes a turning limit member 15 for limiting the extreme position of the turning seat 17 at the discharging station. It can be understood that the discharging station is the station where the material can slide out of the trolley, that is, the turning seat 17 is inclined relative to the horizontal plane, and the inclination angle of the turning seat 17 capable of realizing the discharging function is an angular range. The extreme position of the discharging station refers to the maximum turning angle of the turning seat 17. By setting the turning limit member 15 for the maximum turning angle of the turning seat 17, the impact on the driving member 18 can be avoided. The turning limit member 15 can be a limit beam provided on the tail bracket 4; it can also be a wire rope member. One end of the wire rope member is fixedly connected to the tail bracket 4, and the other end is fixedly connected to the turning seat 17. When the turning seat 17 is in the extreme position, the wire rope member is in a taut state.

[0042] Optionally, the discharging device 1 includes a reset limit member 16 fixedly provided on the tail bracket 4. At the initial station, the turning seat 17 presses against the reset limit member 16. In a specific embodiment, the reset limit member 16 is an I-beam. At the initial station, the turning seat 17 presses against the reset limit member 16, and the reset limit member 16 can support the turning seat 17 at a set height.

[0043] Combined with Figure 4 and Figure 5 , the working process of the above-mentioned discharging device 1 is as follows. The rotary chain 3 has a feeding station and a maintenance hoisting station. Specifically, in the sintering machine system, there is also a feeding device for feeding the trolley in the rotary chain 3 at the feeding station. The feeding device is, for example, a rotary roller feeding device, etc.; at the maintenance hoisting station, the maintenance crane 2 can lift the faulty trolley 5 out of the rotary chain 3 and place it on the turning seat 17.

[0044] In addition, the sintering machine system further includes an air suction device adapted to the trolley on the rotary chain 3. The air suction device is used to provide combustion-supporting gas for the trolley. The air suction devices are in one-to-one correspondence with the trolleys, and each air suction device is connected to the main exhaust fan. The main exhaust fan is used to form a negative pressure.

[0045] Step 1: Confirm the number of the faulty trolley 5 in the rotary chain 3; when the faulty trolley 5 runs to the feeding station of the feeding device, briefly close the feeding device or reduce the feeding amount of the feeding device, so as to reduce the thickness of the sintering material layer of the faulty trolley 5 and reduce the load-bearing requirement of the discharging device 1.

[0046] Step 2: When the faulty trolley 5 runs to the maintenance hoisting station, shut down the sintering machine system and stop the rotary chain 3 from running; move the tail bracket 4 to increase the length of the rotary chain 3, so as to increase the interval between the faulty trolley 5 and the adjacent trolleys, facilitating the maintenance crane 2 to lift out the faulty trolley 5; at the same time, close the air suction device corresponding to the faulty trolley 5 to avoid the loss of pressure of the main exhaust fan.

[0047] Step 3: Place the faulty trolley 5 on the guide rail of the turning seat 17 through the maintenance crane. The faulty trolley 5 can slide to a position where it abuts against the stop wall 12 under the pull of the maintenance motor, or the turning seat 17 can be inclined to enable the faulty trolley 5 to move by itself to a position where it abuts against the stop wall 12. At this time, the spare trolley 6 has been hoisted and placed at the position of the original faulty trolley 5 in the rotary chain 3. Start the unloading device 1, and unload the materials in the faulty trolley 5 into the spare trolley 6.

[0048] Step 4: Reset the tail support 4 and restart the suction device to restart the sintering machine system.

[0049] Among them, the spare trolley 6 can be arranged on the support device of the tail support 4, and the support device is used to form a support with the bottom of the spare trolley 6, so as to facilitate the replacement of the spare trolley 6 and shorten the time required for replacing the trolley.

[0050] In this way, replacing the traditional unloading method significantly improves the unloading efficiency and safety.

[0051] The above has introduced the unloading device 1 provided by the present utility model in detail. Specific examples are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the core idea of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
