Abstract
Description
Technical Field
[0001] This utility model relates to the field of material leakage prevention technology for sintering machines, and in particular to a material leakage prevention structure at the tail of a sintering machine. Background Technology
[0002] The tail section of a sintering machine is typically equipped with a horizontal or swing-type moving frame to prevent problems caused by the expansion of the trolley due to heat. To ensure smooth operation of the moving frame, sufficient clearance must be maintained between the tail section and the tail sealing cover. This clearance can lead to material leakage during unloading. Material leakage not only wastes raw materials but can also obstruct the movement of the moving frame over time, thus affecting the normal operation of the sintering machine.
[0003] In existing sealing technologies for the tail section of sintering machines, the elasticity of rubber is typically used for sealing. This allows the tail sealing cover and the side plate of the moving frame to fit tightly without hindering the movement of the moving frame. However, the sealing strips have a short lifespan due to constant wear from the moving frame and exposure to temperatures exceeding 750°C at the tail of the sintering machine. Furthermore, the side plates of the moving frame and tail sealing cover are approximately 6-10 meters high, making it difficult to maintain straightness after exposure to high temperatures and impacts from falling ore; some degree of warping is inevitable. Even replacing the sealing strips rarely achieves the desired sealing effect, and material leakage between the moving frame and the sealing cover is unavoidable. Over time, this leakage can obstruct the movement of the moving frame, preventing it from offsetting thermal deformation through lateral movement. This leads to increased deformation in other areas, further material accumulation, and even affects the normal operation of the sintering machine.
[0004] Therefore, it is necessary to propose a material leakage prevention structure at the tail of the sintering machine to solve or at least alleviate the above-mentioned defects. Utility Model Content
[0005] The main purpose of this utility model is to provide a leak-proof structure for the tail end of a sintering machine, so as to solve the problem that the existing tail end sealing technology of sintering machines has a short service life and still leaks material after deformation.
[0006] To achieve the above objectives, this utility model provides a leakage prevention structure for the tail end of a sintering machine, including a feed chute, a discharge hopper, and two leakage prevention mechanisms arranged laterally opposite each other; wherein, The unloading hopper is located below the guide chute, and the discharge port of the guide chute faces the guide chute. Each of the aforementioned anti-leakage mechanisms includes a movable frame, a sealing cover, and a receiving hopper. The movable frame is connected to the tail of the sintering machine, the sealing cover is connected to the outside of the guide trough, and a lateral movement gap is reserved between the movable frame and the sealing cover. The receiving hopper is used to receive bulk material from the moving gap. It is connected to the outside of the sealing cover and is located directly below the moving gap, with the discharge end of the receiving hopper facing the unloading hopper.
[0007] Preferably, the receiving hopper is made of channel steel and is inclined, with the lower end of the receiving hopper facing the unloading hopper.
[0008] Preferably, the outer side plate at the lower end of the receiving hopper is inclined and retracted inward.
[0009] Preferably, it further includes a plurality of reinforcing ribs spaced apart along the inclined direction of the outer side plate at the lower end of the receiving hopper, the reinforcing ribs being connected to the inner wall of the outer side plate at the lower end of the receiving hopper.
[0010] Preferably, the lower end of the receiving hopper abuts against the top of the unloading hopper.
[0011] Preferably, the width of the lower end opening of the receiving hopper is greater than the width of the moving gap.
[0012] Preferably, the inner side plate of the receiving hopper extends vertically upward, and its top end is located near the bottom end of the moving gap.
[0013] Preferably, each of the leak-proof mechanisms further includes a sealing strip connected between the movable frame and the sealing cover to seal the movable gap.
[0014] Preferably, the angle between the inclined surface of the receiving hopper and the horizontal plane is 30°~40°.
[0015] Preferably, the receiving hopper is welded to the outside of the sealing cover.
[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a sintering machine tail-end anti-leakage structure, including a guide chute, a discharge hopper, and two anti-leakage mechanisms arranged laterally opposite each other. The discharge hopper is located below the guide chute, and the discharge port of the guide chute faces the guide chute. Each anti-leakage mechanism includes a movable frame, a sealing cover, and a receiving hopper. The movable frame is connected to the tail end of the sintering machine, the sealing cover is connected to the outside of the guide chute, and a movable gap is reserved laterally between the movable frame and the sealing cover. The receiving hopper is used to receive loose material from the movable gap. It is connected to the outside of the sealing cover and located directly below the movable gap, and the discharge end of the receiving hopper faces the discharge hopper. The reserved movement gap does not affect the expansion of the trolley after heating. When the trolley moves the sinter to the tail end to unload, most of the material in the middle of the trolley will be guided into the unloading hopper through the guide chute, while the loose material will fall onto the receiving hopper through the movement gap and be guided into the unloading hopper under the guidance of the receiving hopper. This prevents the loose material from leaking out and accumulating, ensuring the integrity of the unloading process and avoiding affecting the normal operation of the moving frame. The structure is compact, low in cost, and has a long service life. Attached Figure Description

[0025] Please see the appendix Figure 1-4 The present invention provides a sintering machine tail-end anti-leakage structure, comprising a guide chute 10, a discharge hopper 20, and two anti-leakage mechanisms 30 arranged laterally opposite each other. In this application, "lateral" refers to the width direction along the sintering machine trolley. Please refer to the accompanying drawings for details. The specific design is as follows: The unloading hopper 20 is located below the guide trough 10, and the discharge port of the guide trough 10 faces the guide trough 10. Each anti-leakage mechanism 30 includes a movable frame 310, a sealing cover 320, and a receiving hopper 330. The movable frame 310 is connected to the tail of the sintering machine, and the sealing cover 320 is connected to the outside of the guide trough 10. A horizontal movement gap 340 is reserved between the movable frame 310 and the sealing cover 320. The receiving hopper 330 is used to receive loose material from the movement gap 340. It is connected to the outside of the sealing cover 320 and located directly below the movement gap 340. The discharge end of the receiving hopper 330 faces the unloading hopper 20.
[0026] Specifically, the anti-leakage structure at the tail of the sintering machine in this application includes a guide chute 10, a discharge hopper 20, and two anti-leakage mechanisms 30 arranged laterally opposite each other. The guide chute 10 is used to guide most of the material to a single-roll crusher (not shown in the figure). The crushed material will flow into the discharge hopper 20, which is used to temporarily store and unload the material from the sintering machine trolley. Therefore, the discharge hopper 20 is located below the guide chute 10 to facilitate material receiving, and the discharge port of the guide chute 10 is set towards the guide chute 10 to ensure that the material can enter the discharge hopper 20. The anti-leakage mechanism 30 is used to prevent some loose material from leaking out, avoiding material accumulation that could affect the normal operation of the trolley.
[0027] Each of the anti-leakage mechanisms 30 includes a movable frame 310, a sealing cover 320, and a receiving hopper 330. The movable frame 310 is connected to the tail of the sintering machine to prevent problems caused by the expansion of the trolley after heating. The sealing cover 320 is used to prevent materials from falling from both sides. Therefore, the sealing cover 320 is connected to the outside of the guide chute 10. To ensure the smooth operation of the movable frame 310 (moving laterally), a sufficient movement gap 340 needs to be left between the movable frame 310 at the tail of the sintering machine and the tail sealing cover 320. In this way, in addition to most of the material being crushed and guided into the discharge hopper by the guide chute 10, some loose material will fall out through the movement gap 340. If material leaks and accumulates, severe accumulation can affect the lateral movement of the moving frame 310. Eventually, the thermal deformation cannot be offset by lateral movement, leading to increased deformation in other areas, more material accumulation, and even affecting the normal operation of the sintering machine. This application adds a receiving hopper 330, which is connected to the outside of the sealing cover 320 and positioned directly below the moving gap 340. This hopper is used to receive loose material from the moving gap 340. When loose material leaks, it falls into the receiving hopper 330 below and is then guided by the receiving hopper 330 to flow from the outlet end into the unloading hopper 20, thus ensuring that all material is ultimately introduced into the unloading hopper 20 and preventing leakage and accumulation.
[0028] Furthermore, each of the leak-proof mechanisms 30 also includes a sealing strip 360, which is connected between the movable frame 310 and the sealing cover 320 to seal the movable gap 340.
[0029] It should be noted that the sealing strip 360 can use the elasticity of rubber to seal, so that the tail sealing cover 320 and the side plate of the moving frame 310 can fit tightly, while not affecting the movement of the moving frame 310. This ensures a good sealing effect in the early stage of operation. However, when the sealing strip is worn by the moving frame 310 for a long time and is subjected to the high temperature of 750°C or above at the tail of the sintering machine, resulting in a short lifespan and some warping, the receiving hopper 330 can be used as a second layer of protection. This forms a double layer of protection to prevent the leakage and accumulation of loose material, thus ensuring that the overall structural protection measures are in place.
[0030] In a preferred embodiment of the present invention, the receiving hopper 330 is made of channel steel and is inclined, with the lower end of the receiving hopper 330 facing the unloading hopper 20.
[0031] It should be noted that the channel steel is designed with an opening forming two side plates and a bottom plate to facilitate the receiving and output of materials. It is inclined to create an internal slope, allowing the material to slide down the slope under gravity and be guided towards the unloading hopper 20. In a preferred embodiment of this application, the angle between the inclined surface of the receiving hopper 330 and the horizontal plane is 30°~40°, preferably 35°, as the most suitable inclination for the discharge volume and speed. The specific angle can also be selected by those skilled in the art according to actual needs.
[0032] In a preferred embodiment of the present invention, the outer side plate at the lower end of the receiving hopper 330 is inclined and retracted inward.
[0033] It should be noted that the inward-convex design forms a converging structure, which facilitates the inward convergence of materials to dock with the unloading hopper 20. The inner side plate of the receiving hopper 330 is used to install the structure that connects to the vertical plate, while the outer side plate at the lower end is machined to be inclined inward to gradually converge.
[0034] As a preferred embodiment of the present invention, it further includes a plurality of reinforcing ribs 350 arranged at intervals along the inclined direction of the outer side plate at the low end of the receiving hopper 330, the reinforcing ribs 350 being connected to the inner wall of the outer side plate at the low end of the receiving hopper 330.
[0035] It is worth noting that the rib plate 350 can accumulate some material to form a material-grinding structure, thereby increasing the service life of the receiving hopper 330. Preferably, there are two rib plates 350 in this application, and the two rib plates 350 are arranged at intervals along the inclined direction of the outer side plate at the lower end. The specific number can be selected according to the length of the inclined outer side plate.
[0036] In a preferred embodiment of the present invention, the lower end of the receiving hopper 330 abuts against the top end of the unloading hopper 20.
[0037] It is worth noting that the lower end of the receiving hopper 330 is the discharge port. Thus, the discharge port is directly connected to the top of the unloading hopper 20. After flowing out, it is directly introduced into the unloading hopper 20, ensuring a seamless connection of material discharge and further ensuring the anti-leakage effect.
[0038] Furthermore, the width of the lower end opening of the receiving hopper 330 is greater than the width of the moving gap 340.
[0039] It should be noted that the moving gap 340 changes due to the left and right movement of the moving frame 310, and the width of the opening at the lower end of the receiving hopper 330 is always greater than the width of the moving gap 340. This ensures that the entire receiving range of the receiving hopper 330 is used to cover the outside of the moving gap 340, so as to ensure that the loose material will not leak out due to the increase of the moving gap 340, thereby ensuring the anti-leakage performance.
[0040] Furthermore, the inner side plate of the receiving hopper 330 extends vertically upward, and its top end is located near the bottom end of the moving gap 340.
[0041] It should be understood that, in addition to the installation connection, the inner side plate extends vertically upward to the bottom of the moving gap 340, which can play a certain guiding role for the loose material flowing out through the moving gap 340, so as to guide the loose material to fall into the receiving hopper 330.
[0042] Furthermore, the receiving hopper 330 is welded to the outside of the sealing cover 320.
[0043] Understandably, welding offers better stability and is easier to process.
[0044] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
