Description

Technical Field

[0001] The utility model relates to the technical field of flat material conveying for sintering machines, in particular to a flat material device for sintering machines. Background Art

[0002] The sintering machine is suitable for the sintering operation of large-scale ferrous metallurgical sintering plants, and is mainly suitable for the sintering treatment of iron ore powder in large and medium-sized sintering plants. It is the main equipment in the exhaust sintering process, which can sinter concentrate powder and rich ore powder of different components and different particle sizes into blocks, and partially eliminate harmful impurities such as sulfur and phosphorus contained in the ore. Sintering machines are divided into several specifications of different lengths and widths according to the sintering area, and users can choose according to their output or site conditions. The larger the sintering area, the higher the output. The existing sintering machine trolley has the problem of incomplete edge distribution, which makes the edge ignition effect poor, the sintering liquid phase formation is not good, and the return rate is high, affecting the sintering utilization coefficient. The main reason is that the existing flat material device structure is too simple, and it is difficult to solve the problem of lack of material on the edge of the trolley, so that the edge lack of material phenomenon continues to develop, and eventually leads to edge lack of material.

[0003] Chinese utility model patent: Publication number CN211782744U discloses a flat material device for a sintering machine, including a flat material scraper, which is horizontally arranged, and slide grooves are provided at both ends of the flat material scraper along its length direction, and side scrapers are slidably connected in the slide grooves, and a control mechanism for controlling the sliding of the side scrapers is provided in the slide grooves, and the flat material scraper is vertically connected to a lifting mechanism for controlling its movement in the vertical direction.

[0004] In the existing technology, when CN211782744U is in use, the flattening scraper falls onto the surface of the material under the action of the lifting mechanism, and then the control mechanism controls the side scraper to slide in the chute so that the side scraper is close to the side guard plate of the trolley, so that the working range of the flattening device can be flexibly adjusted, and at the same time, the material distribution effect is improved, so that the material distribution at the edge of the trolley is full and the edge ignition effect is improved. However, in actual use, the flattening device can be used to flatten the material during the loading process. However, during the material conveying stage, due to the undulations of the track, the material will still shake during the conveying stage, resulting in a shortage of material at the edge of the material car. Therefore, a sintering machine flattening device is needed to solve the above problems. Utility Model Content

[0005] The utility model aims to provide a material leveling device for a sintering machine, which has the advantage of keeping materials level during the material conveying stage, and solves the problem in the prior art that materials are still missing from the edges of the material cart during the conveying stage after the materials are leveled.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sintering machine flat material device, comprising a carriage body, a storage groove is movably installed inside the carriage body, a storage eave is fixedly installed on the top of the carriage body, and also includes a first spring body and a positioning frame;

[0007] The first spring body is arranged at the four corners of the upper surface of the placement eaves;

[0008] The positioning frame is fixedly installed in the middle of the bottom of the carriage body;

[0009] Wherein, a counterweight block is movably installed on the positioning frame.

[0010] When using a sintering machine leveling device in the technical solution, a storage trough is placed in the carriage body, so that the storage trough is supported by the limiting eaves, and the storage trough is supported in cooperation with the first spring body. Therefore, when the carriage body is traveling and encounters shaking, the storage trough can be displaced in the vertical direction in the carriage body through the first spring body, thereby re-oscillating the material injected into the storage trough and spreading the material flat in the storage trough. At the same time, when the carriage body is traveling and encounters shaking, the counterweight block moves horizontally on the inner side of the positioning frame, and the carriage body is horizontally oscillated under the action of the second spring body, thereby realizing the flattening operation of the material in the storage trough.

[0011] Preferably, mounting frames are fixedly mounted on the front and rear ends of the lower surface of the carriage body, and weight-reducing grooves are equidistantly provided on the bottom of the carriage body.

[0012] By setting a weight-reducing groove at the bottom of the carriage body, the bottom of the carriage body can be made hollow when in use, thereby preventing material from remaining inside the carriage body during filling and unloading, thereby preventing the bottom of the storage slot from being damaged due to bumps caused by material residue.

[0013] Preferably, there are four mounting frames, and guide wheels are rotatably mounted on the inner sides of the four mounting frames.

[0014] The guide wheel is installed by rotating on the inner side of the mounting frame, so that the carriage body can be moved in the horizontal direction through the sliding of the guide wheel and the guide rail.

[0015] Preferably, a limiting eaves is fixedly installed on the top of the storage groove, a retaining frame is fixedly installed on the top of the limiting eaves, and the outer diameter of the storage groove matches the inner diameter of the carriage body.

[0016] By fixing a retaining frame on the limiting eaves, the retaining frame can be used to shield the materials injected into the storage tank during use, thereby preventing the materials from spilling from the storage tank and causing waste during use.

[0017] Preferably, the outer dimension of the placement eaves is smaller than the outer dimension of the limiting eaves.

[0018] By making the size of the limiting eaves larger than the size of the placing eaves, the placing trough can be taken out from the carriage body through the limiting eaves during use, thereby realizing the discharging operation.

[0019] Preferably, the bottom of the first spring body is elastically mounted on the upper surface of the placement eaves, and the top of the first spring body is in contact with the lower surface of the limiting eaves but not fixedly connected.

[0020] By making the top of the first spring body contact with the lower surface of the limiting eaves but not fixedly connected, the storage groove can be supported by the first spring body during use, and when the carriage body shakes, the storage groove can shake up and down in the carriage body.

[0021] Preferably, the positioning frames on both sides of the counterweight block are movably mounted with second spring bodies, and the opposite sides of the two second spring bodies are elastically connected to the inner sides of the positioning frames respectively.

[0022] The counterweight block is slidably mounted on the positioning frame, and under the action of the second spring body, the carriage body can be made to perform overall horizontal oscillation when the carriage body is horizontally swayed.

[0023] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0024] The utility model provides a storage groove and places the storage groove in the carriage body, so that the storage groove is supported by the limiting eaves, and the storage groove is supported in cooperation with the first spring body. Therefore, when the carriage body is traveling and encounters shaking, the storage groove can be displaced in the vertical direction in the carriage body through the first spring body, and then the material injected into the storage groove is re-oscillated and spread flat in the storage groove. At the same time, when the carriage body is traveling and encounters shaking, the counterweight block moves in the horizontal direction on the inner side of the positioning frame, and the carriage body is oscillated in the horizontal direction under the action of the second spring body, thereby achieving the effect of keeping the material flat during the material transportation stage.

[0033] Specifically, the first spring body 6 is arranged at the four corners of the upper surface of the placement eaves 7; the positioning frame 9 is fixedly installed in the middle of the bottom of the carriage body 2; wherein, a counterweight 10 is movably installed on the positioning frame 9. By setting the storage slot 5 and placing the storage slot 5 in the carriage body 2, the storage slot 5 is supported by the limiting eaves 3, and the storage slot 5 is supported by the first spring body 6, so that when the carriage body 2 is running and encountering shaking, the storage slot 5 can be displaced in the vertical direction in the carriage body 2 through the first spring body 6, and then the material injected into the storage slot 5 is re-oscillated and laid flat in the storage slot 5. At the same time, when the carriage body is running and encountering shaking, the counterweight 10 moves horizontally inside the positioning frame 9, and the carriage body 2 is horizontally oscillated under the action of the second spring body 11, so as to achieve the effect of keeping the material flat during the material conveying stage.

[0034] Furthermore, mounting frames 1 are fixedly mounted on the front and rear ends of the lower surface of the carriage body 2 , and weight-reducing grooves 12 are equidistantly provided at the bottom of the carriage body 2 .

[0035] By setting a weight-reducing groove 12 at the bottom of the carriage body 2, the bottom of the carriage body can be hollowed out during use, thereby preventing material from remaining inside the carriage body 2 during filling and unloading, thereby preventing the bottom of the storage slot 5 from being damaged due to bumps caused by material residue.

[0036] Furthermore, there are four mounting frames 1 , and guide wheels 8 are rotatably mounted on the inner sides of the four mounting frames 1 .

[0037] By rotating and installing the guide wheel 8 on the inner side of the mounting frame, the carriage body 2 can be moved in the horizontal direction through the sliding of the guide wheel 8 and the guide rail.

[0038] Furthermore, a limiting eaves 3 is fixedly installed on the top of the storage groove 5, and a retaining frame 4 is fixedly installed on the top of the limiting eaves 3. The outer diameter of the storage groove 5 matches the inner diameter of the carriage body 2.

[0039] By fixing the retaining frame 4 on the limiting eaves 3, the retaining frame 4 can shield the materials injected into the storage groove 5 during use, thereby preventing the materials from spilling from the storage groove 5 and causing waste during use.

[0040] Furthermore, the outer dimension of the placement eaves 7 is smaller than the outer dimension of the limiting eaves 3 .

[0041] By making the size of the limiting eaves 3 larger than the size of the placing eaves 7, when in use, the placing trough 5 can be taken out from the carriage body 2 through the limiting eaves 3, thereby realizing the discharging operation.

[0042] Furthermore, the bottom of the first spring body 6 is elastically mounted on the upper surface of the placement eaves 7, and the top of the first spring body 6 is in contact with the lower surface of the limiting eaves 3 but not fixedly connected.

[0044] Furthermore, the positioning frames 9 on both sides of the counterweight 10 are movably mounted with second spring bodies 11 , and the two second spring bodies 11 are elastically connected to the inner side of the positioning frames 9 at opposite sides thereof.

[0045] The counterweight block 10 is slidably mounted on the positioning frame 9 , and under the action of the second spring body 11 , the vehicle body 2 can be horizontally vibrated as a whole when the vehicle body 2 is horizontally shaken.

[0046] When the utility model is used, the storage groove 5 is placed in the carriage body 2, so that the storage groove 5 is supported by the limiting eaves 3, and the storage groove 5 is supported in cooperation with the first spring body 6. Therefore, when the carriage body 2 is traveling and encounters shaking, the storage groove 5 can be displaced in the vertical direction in the carriage body 2 through the first spring body 6, and then the material injected into the storage groove 5 is re-oscillated and spread flat in the storage groove 5. At the same time, when the carriage body is traveling and encounters shaking, the counterweight block 10 moves horizontally on the inner side of the positioning frame 9, and the carriage body 2 is horizontally oscillated under the action of the second spring body 11, thereby realizing the flattening operation of the material in the storage groove 5.
