Description

Technical Field

[0001] This utility model relates to belt decarbonization machines, and more particularly to composite side panels in the trolleys of coal gangue belt decarbonization machines. Background Technology

[0002] Coal gangue is a solid waste generated during coal mining and washing, and it is one of the largest and most widely distributed industrial wastes in my country in terms of both accumulation and annual production. The belt decarburizer is the core process equipment in a coal gangue decarburization production line. It ignites, decarburizes, and cools raw coal gangue, ultimately producing finished coal gangue ore that meets process requirements. The belt decarburizer consists of a trolley, the main body of the equipment, a transmission system, a lubrication system, a furnace hood system, and a crushing device. The trolley is the moving carrier used to transport the coal gangue; ignition, decarburization, and cooling of the raw coal gangue all need to be completed on the trolley.

[0003] Coal gangue requires a sealed environment during ignition roasting, decarburization (normal decarburization temperature is between 700℃ and 900℃), and cooling processes, while the sideboards of the trolley... Figure 1 As shown, it consists of an upper side panel and a lower side panel. The lower side panel is fixed to the end of the trolley with bolts. The upper and lower side panels are connected by bolts. After being fired at high temperature and cooled by forced air, the upper and lower side panels will expand and contract due to heat, which will cause deformation and cracks. This can easily lead to gaps at the connection between the upper and lower side panels and between the lower side panel and the trolley, resulting in air leakage, high temperature radiation, and insufficient decarburization. When the upper or lower side panel is damaged, the process of replacing the upper and lower side panels is quite complicated. Utility Model Content

[0004] The purpose of this invention is to provide a composite sideboard in a coal gangue belt decarbonization machine trolley that can effectively prevent damage to the upper and lower sideboards from affecting normal operation.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a composite sideboard in a coal gangue belt decarbonization machine trolley, with a receiving plate integrally extended from the outer side of the trolley end, a lower sideboard connected to the receiving plate, an upper sideboard connected to the lower sideboard, a lower guard plate provided on the inner side of the trolley end, the lower guard plate abutting against the trolley end, an upper limit plate provided on the top of the lower guard plate, the upper limit plate abutting against the inner wall of the lower sideboard, a refractory fiberboard inserted in the lower guard plate, and a screw threaded between the lower guard plate and the receiving plate. The inner end of the rod is provided with a stop block that abuts against the lower guard plate and the trolley. The outer end of the screw is threaded with a locking nut that abuts against the receiving plate. The lower guard plate and the lower rail plate are connected by a first bolt. An upper guard plate is provided on the lower guard plate. A lower limit plate is provided at the bottom of the upper guard plate. The lower limit plate rests on the upper limit plate and abuts against the inner side wall of the lower rail plate. A fire-resistant fiberboard is inserted in the upper guard plate. The upper guard plate and the upper rail plate are connected by a second bolt. A baffle is provided on the upper guard plate. The baffle is connected to the upper rail plate by a third bolt.

[0006] Furthermore, in the aforementioned composite sideboard of the coal gangue belt decarbonization machine trolley, a transverse partition is provided in the lower guard plate, which is located above the joint between the receiving plate and the lower sideboard. Two refractory fiberboards are embedded in the lower guard plate, and the transverse partition separates the two refractory fiberboards in the lower guard plate. The joint between the upper limit plate on the lower guard plate and the lower limit plate on the upper guard plate is staggered from the joint between the upper sideboard and the lower sideboard.

[0007] Furthermore, in the aforementioned composite sideboard of the coal gangue belt decarbonization machine trolley, countersunk holes are provided on the upper guard plate, lower guard plate, and baffle plate. The large-diameter end of the countersunk hole is hexagonal in shape, and the hexagonal heads of the first bolt, the second bolt, and the third bolt are inserted into the large-diameter end of the corresponding countersunk hole.

[0008] Furthermore, in the aforementioned composite sideboard of the coal gangue belt decarbonization machine trolley, the connection structure between the receiving plate and the lower sideboard is as follows: a first support plate extends outward from the top of the receiving plate, and a slot is provided on the first support plate; a second support plate extends outward from the bottom of the lower sideboard, and a locking block extends downward from the second support plate; the second support plate on the lower sideboard abuts against the first support plate of the receiving plate; the slot on the first support plate engages with the locking block on the second support plate; and the first and second support plates are connected by a fourth bolt.

[0009] Furthermore, in the aforementioned composite sideboard of the coal gangue belt decarbonization machine trolley, the connection structure between the upper and lower sideboards is as follows: a third support plate extends outward from the top of the lower sideboard, a fourth support plate extends outward from the bottom of the upper sideboard, a sealing plate is provided between the third and fourth support plates, and the third support plate, the sealing plate, and the fourth support plate are connected by a fifth bolt.

[0010] Furthermore, in the aforementioned composite sideboard of the coal gangue belt decarbonization machine trolley, a first inclined guide portion is provided on the upper sideboard at an upward and outward angle, and a second inclined guide portion is provided on the upper guard plate at an upward and outward angle. The first and second inclined guide portions are parallel to each other, and a baffle is provided on the second inclined guide portion.

[0011] The advantages of this utility model are as follows: A receiving plate is integrally extended at the end of the trolley, and a lower side plate and an upper side plate are sequentially connected to the receiving plate. A lower guard plate and an upper guard plate are provided on the inner side of the trolley end, and a refractory fiber plate is embedded in the upper guard plate and the lower guard plate. In this way, the coal gangue in the trolley acts directly on the lower guard plate and the upper guard plate without damaging the receiving plate, the lower side plate, and the upper side plate. Moreover, temperature changes in the trolley also act directly on the trolley body and the upper and lower guard plates. Since the receiving plate and the end of the trolley are integrally formed, when the trolley expands and contracts due to temperature changes, there is no gap between the trolley and the receiving plate. Cracks are prone to occur, but the refractory fiberboard in the upper and lower guard plates can provide insulation. While ensuring the thermal insulation and sealing of the trolley, it also prevents temperature changes inside the trolley from being easily transmitted to the lower and upper guard plates, thus preventing deformation and cracking of the lower and upper guard plates due to temperature changes. The refractory fiberboard has a low coefficient of expansion, and can maintain good dimensional stability and structural integrity after being heated, without compressing the lower and upper guard plates, thereby further protecting them. When the upper or lower guard plate is damaged, replacing the damaged upper or lower guard plate can ensure the normal operation of the equipment. Attached Figure Description

[0014] The technical solution of this utility model will be further described below with reference to the accompanying drawings and preferred embodiments.

[0015] like Figure 2As shown, the composite sideboard of the coal gangue belt decarbonization machine trolley of this utility model has a supporting plate 11 integrally extended from the outer end of the trolley 1. A lower sideboard 2 is connected to the supporting plate 11. The connection structure between the supporting plate 11 and the lower sideboard 2 is as follows: a first support plate 111 extends outward from the top of the supporting plate 11, and a slot is provided on the first support plate 111; a second support plate 21 extends outward from the bottom of the lower sideboard 2, and a locking block extends downward from the second support plate 21; the second support plate 21 on the lower sideboard 2 abuts against the first support plate 111 of the supporting plate 11; the slot on the first support plate 111 and the second support plate 2... The locking blocks on plate 1 engage to facilitate positioning and connection between the lower plate 2 and the receiving plate 11. The first support plate 111 and the second support plate 21 are connected by a fourth bolt 12. An upper plate 3 is connected to the lower plate 2. The connection structure between the upper plate 3 and the lower plate 2 is as follows: a third support plate 22 extends outward from the top of the lower plate 2, a fourth support plate 31 extends outward from the bottom of the upper plate 3, a sealing plate 23 is provided between the third support plate 22 and the fourth support plate 31, and the third support plate 22, the sealing plate 23 and the fourth support plate 31 are connected by a fifth bolt 13. A first inclined guide part 32 is provided on the upper plate 3 at an upward and outward angle.

[0016] A lower guard plate 4 is provided on the inner side of the end of the trolley 1, with a gap between the lower guard plate 4 and the trolley 1 to facilitate the installation of the lower guard plate 4. The bottom of the lower guard plate 4 abuts against the end of the trolley 1 and is parallel to the supporting plate 11 and the lower side plate 2. An upper limit plate 41 is provided on the top of the lower guard plate 4, abutting against the inner wall of the lower side plate 2. A transverse partition 42 is provided in the lower guard plate 4, located above the joint between the supporting plate 11 and the lower side plate 2 and abutting against the inner wall of the lower side plate 2. Two refractory fiberboards 5 are provided between the lower guard plate 4 and the supporting plate 11 and the lower side plate 2. The transverse partition 42 separates the two refractory fiberboards 5 on the lower guard plate 4. The refractory fiberboards 5 located below the transverse partition 42 are... The support plate 5 is abutted against the joint between the receiving plate 11 and the lower guard plate 2, thus preventing heat from the trolley 1 from leaking out through the joint between the receiving plate 11 and the lower guard plate 2. A screw 43 is inserted between the lower guard plate 4 and the receiving plate 11. A stop block 431 is provided at the inner end of the screw 43, which abuts against the lower guard plate 4 and the trolley 1. A locking nut is threaded to the outer end of the screw 43, which abuts against the receiving plate 11. Through the tightening action between the screw 43 and the locking nut, the stop block 431 can abut against the lower guard plate 4, thereby sealing the gap between the lower guard plate 4 and the trolley 1 and preventing coal gangue from getting stuck in the gap between the lower guard plate 4 and the trolley 1. The lower guard plate 4 and the lower guard plate 2 are connected by a first bolt 24. Bolt 24 serves to connect the lower guard plate 2, the fire-resistant fiberboard 5, and the lower protective plate 4, and also strengthens the connection between the lower guard plate 2, the fire-resistant fiberboard 5, and the lower protective plate 4. An upper protective plate 6 is installed on the lower protective plate 4, and a lower limiting plate 61 is installed at the bottom of the upper protective plate 6. The lower limiting plate 61 of the upper protective plate 6 rests on the upper limiting plate 41 of the lower protective plate 4. The joint between the upper limiting plate 41 and the lower limiting plate 61 is staggered from the joint between the upper guard plate 3 and the lower guard plate 2. The lower limiting plate 61 of the upper protective plate 6 abuts against the inner wall of the lower guard plate 2. A second inclined guide portion 62 is installed on the upper protective plate 6, tilted upwards and outwards, parallel to the first inclined guide portion 32 on the upper guard plate 3. A fire-resistant fiberboard 5 is provided between the upper guard plate 61 and the lower guard plate 2 and the upper guard plate 3. The fire-resistant fiberboard 5 at this position is attached to the joint between the upper guard plate 3 and the lower guard plate 2 to prevent heat in the trolley 1 from leaking out from the joint. The upper guard plate 6 and the upper guard plate 3 are connected by a second bolt 33. The second bolt 33 not only connects the upper guard plate 3, the fire-resistant fiberboard 5 and the upper guard plate 6, but also strengthens the connection between the upper guard plate 3, the fire-resistant fiberboard 5 and the upper guard plate 6. A baffle 621 is provided on the second inclined guide part 62 of the upper guard plate 6. The baffle 621 is placed on the fire-resistant fiberboard 5 between the upper guard plate 62 and the lower guard plate 2 and the upper guard plate 3 and is connected to the upper guard plate 3 by a third bolt 34.

[0017] When the trolley 1 is loaded with coal gangue for roasting, decarburization, and cooling, the lower guard plate 4 and upper guard plate 6 are directly affected by the temperature. The lower guard plate 4 and upper guard plate 6 transfer heat to the refractory fiberboard 5. The refractory fiberboard 5 not only blocks heat from escaping from the trolley 1, but also has a low coefficient of thermal expansion. The low coefficient of thermal expansion after heating helps maintain good dimensional stability and structural integrity, and prevents compression of the lower guard plate 4, upper guard plate 6, lower side plate 2, and upper side plate 3. When the coal gangue falls into the trolley 1, the second inclined guide section 62 of the upper guard plate 6 acts as a guide, allowing the coal gangue to fall smoothly into the trolley 1. When the coal gangue impacts the second inclined guide section 62 of the upper guard plate 6, the impact force is transferred to the first inclined guide section 32 of the upper side plate 3, and the upper side plate 3 is subjected to this impact. The force will act downwards on the lower guard plate 2, while the sealing plate 23 between the upper guard plate 3 and the lower guard plate 2 acts as a buffer, reducing the impact force between the upper guard plate 3 and the lower guard plate 2. This reduces damage to the upper guard plate 3 and the lower guard plate 2, and also reduces noise. The coal gangue in the trolley 1 acts on the lower guard plate 4 and the upper guard plate 6. The upper guard plate 6 and the lower guard plate 4 are easily damaged. After the upper guard plate 6 and the lower guard plate 4 are damaged, due to the barrier effect of the refractory fiber board 5, the heat inside the trolley 1 is not easily transferred to the lower guard plate 2 and the upper guard plate 3. The lower guard plate 2 and the upper guard plate 3 are in contact with the outside normal temperature environment and are not easily affected by the high temperature inside the trolley 1. The temperature of the lower guard plate 2 and the upper guard plate 3 is relatively stable and is not easily affected by the temperature change of the trolley 1, so they are not easily damaged. When either the upper guard plate 6 or the lower guard plate 4 is damaged, it is only necessary to replace the damaged upper guard plate 6 or the lower guard plate 4.

[0018] When replacing the upper guard plate 6 or the lower guard plate 4 and disassembling or tightening the corresponding bolts, the bolts need to be fixed first, and then the nuts on the bolts need to be tightened. The conventional operation is to use a socket wrench to hold the hexagonal head of the corresponding bolt to limit the bolt. However, since the first bolt 24 passes through the lower guard plate 4 and the lower rail 2, the second bolt 33 passes through the upper guard plate 6 and the upper rail 3, and the third bolt 34 is located at the top of the upper guard plate 6 and the upper rail 3, the hexagonal head of the bolt is either inside the trolley 1 or at a higher position at the top. This requires the operator to enter the inside of the trolley 1 to fix the first bolt 24 and the second bolt 33, and to use a ladder to reach the same height to fix the third bolt 34, which is not conducive to replacing the upper guard plate 6 and the lower guard plate 4.

[0019] To facilitate the replacement of the upper guard plate 6 and the lower guard plate 4, countersunk holes are provided on the upper guard plate 6, the lower guard plate 4, and the baffle 621. The large-diameter end of the countersunk hole is hexagonal. The hexagonal heads of the first bolt 24, the second bolt 33, and the third bolt 34 are inserted into the hexagonal large-diameter end of the corresponding countersunk hole. When the first bolt 24, the second bolt 33, or the third bolt 34 is screwed on, the hexagonal head of the corresponding bolt is locked in place by the large-diameter end of the countersunk hole and cannot be rotated. No additional tools or methods are needed to restrict the bolts. Only one worker needs to screw the nut onto or off the corresponding bolt by screwing it on the outside of the trolley 1, which greatly improves the replacement efficiency.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this utility model. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the protection scope of the claims of this utility model.
