Description

Technical Field

[0001] The present invention relates to the field of sintering pallets, and particularly to a sintering machine pallet and a processing method thereof. Background Art

[0002] A sintering machine pallet is an important device used in the sintering process, mainly used to convert various raw materials into sintered bodies with certain shapes and properties through a high-temperature sintering process. The sintering machine pallet is usually made of high-temperature resistant materials and can withstand a long-term high-temperature environment without deformation or damage. During the sintering process, the pallet moves along a predetermined path in the sintering furnace to ensure that the raw materials are evenly heated, thereby achieving a high-quality sintering effect. The design and manufacture of the sintering machine pallet need to consider various factors, such as temperature distribution, thermal expansion, corrosion resistance, etc., to ensure its reliability and stability in practical applications.

[0003] There is now a heat preservation and energy-saving sintering pallet for ultra-thick material layer sintering process in Chinese patent document CN202021038216.4, including: a pallet body with an accommodation cavity for accommodating sintered materials inside, the top of the accommodation cavity is open, and wheels suitable for rolling on the track are provided at the bottom of the pallet body; heat-insulating materials covering the outer side wall of the pallet body. The heat preservation and energy-saving sintering pallet of the present invention greatly enhances the heat preservation effect at the outer wall of the sintering pallet by covering heat-insulating materials on the outer side wall of the pallet body. During sintering, the temperature at the outer wall of the sintering pallet can be reduced by about 30%. When the sintered materials are sintered in the sintering pallet, the amount of heat radiated outward from the outer wall of the sintering pallet is reduced, and the under-burning of the sintered materials is reduced. Therefore, not only the consumption of solid fuel is reduced, but also the output of sintered ore is increased.

[0004] However, the above patent has certain defects in use. In view of the fact that this sintering pallet adopts the ultra-thick material layer sintering technology to achieve the heat preservation and energy-saving effect, and the heat preservation performance of the outer wall of the sintering pallet is significantly improved by laying heat-insulating materials on the outer side wall of the pallet body. However, the application of the ultra-thick material layer also leads to an increase in the overall weight of the sintering pallet, which increases the overall load during long-term sintering operations, reduces the running stability, and affects the sintering efficiency and equipment life.

[0005] Therefore, a sintering machine pallet and a processing method thereof are proposed here to solve the above problems. Summary of the Invention

[0006] In order to overcome the problem of the over-thick side plates of the sintering pallet caused by improving the heat preservation performance in the prior art, the present invention provides a sintering machine pallet and a processing method thereof.

[0007] The present invention is realized by adopting the following technical solutions:

The support beam is provided with a plurality of ventilation grids in a penetrating manner, and a plurality of grate bars are clamped between the top of the support beam and the trolley main body. The plurality of grate bars and the trolley main body form a sealed first cavity, and a plurality of first openings penetrate the trolley main body at both sides of the first cavity;

[0009] There are two car side walls, which are located on both sides of the trolley main body. The two car side walls are provided with a plurality of second openings in a penetrating manner.

[0012] Sliding rails are arranged at the bottoms of the two side plates, and the sliding rails are located beside the separation plates. Positioning blocks are arranged at the ends of the sliding rails, and the sliding rails and the chutes are in an assembled relationship.

[0013] As a preferred scheme of the present invention, a plurality of separation plates are arranged at the bottoms of the two side plates. The plurality of separation plates are located directly above the plurality of second openings. A top cover is arranged at the top ends of the two side plates. A plurality of ignition ports penetrate the top cover, and a plurality of third positioning bolts are arranged beside the plurality of ignition ports.

[0014] As a preferred scheme of the present invention, second through holes penetrate through the two car side walls and the two side plates beside them. Second positioning bolts are threadedly connected to the second through holes, and second nuts are arranged at the ends of the second positioning bolts for fastening.

[0015] As a preferred scheme of the present invention, a side bar is arranged on the top of the top cover. A plurality of third through holes penetrate through the inner side of the side bar, and the plurality of third through holes are threadedly installed on the third positioning bolts, and third nuts are arranged at the ends of the third positioning bolts for fastening.

[0016] As a preferred scheme of the present invention, dust-proof grilles are arranged at the joints of the air bridge pipes with the first openings and the second openings, and a plurality of first through holes penetrate through both ends of the air bridge pipes;

[0017] A plurality of first positioning bolts are provided between the bottom wall of the vehicle side enclosure and the side wall of the trolley. The first through holes are threadedly connected to the first positioning bolts, and the ends of the first positioning bolts are provided with first nuts for fastening.

[0018] As a preferred embodiment of the present invention, a plurality of connecting beams are provided in the second cavity, and a plurality of the connecting beams are cross-connected with second reinforcing ribs;

[0019] The outer wall surfaces of the two side plates are provided with a plurality of first reinforcing ribs of different sizes, and the inner walls of the two side plates are in an arc shape.

[0020] As a preferred embodiment of the present invention, a plurality of reinforcing bearings are provided on both sides of the trolley body. A plurality of the reinforcing bearings are connected to wheels. A support leg frame is provided above the plurality of reinforcing bearings, and the support leg frame is located on both sides of the trolley body. The other ends of the plurality of support frames are connected to the two vehicle side enclosures.

[0021] A sintering machine trolley and its processing method include the following steps:

[0022] S1. Installation: Align the slide rails at the bottom of the side plate with the chute for assembly. When the slide rail reaches the end of the chute, the positioning block is inserted into the installation groove accordingly. The second through holes on the side plate and the vehicle side enclosure correspond to each other. Thread the second positioning bolts into the second through holes, and then tighten the second nuts for fastening. The side plate is firmly fixed on the top of the vehicle side enclosure;

[0023] Threadedly connect the first through holes at both ends of the air bridge pipe to the first positioning bolts, and tighten the first nuts for fastening to ensure a stable connection.

[0024] S2. Connection: When there is too much sintering material, thread a plurality of third through holes inside the side rail onto the third positioning bolts, and fix the third nuts for fastening.

[0025] S3. Heat preservation: During the sintering process, the temperature of the first cavity at the bottom of the grate bar is the highest, and the temperature of the second cavity provided inside the side plate is relatively low. The heat energy enters the air bridge pipe through a plurality of first openings. The air bridge pipe transfers the heat energy to the second opening, and then the heat energy enters the second cavity, enhancing the internal temperature of the second cavity, achieving uniform heat distribution between the trolley body and the side plate. When the sintering trolley moves horizontally, the diversion nozzles will continuously introduce external cold air into the second cavity, so that the heat energy in the first cavity always flows to the second cavity.

[0026] S4. Filtration: During the sintering process, the dust-proof grille prevents dust from entering. When the sintering trolley is ignited and heated, a plurality of ignition openings on the top cover will introduce high temperature into the second cavity. The second cavity will transfer the high temperature to the first cavity through a plurality of air bridge pipes, improving the sintering efficiency. The separation plate at the bottom of the side plate isolates the heat energy from the cold air, and the cold air is separated, so as to keep the temperature of the trolley body and the two side plates always uniform for efficient sintering.

[0027] Compared with the prior art, the advantages of the present invention are as follows:

[0028] 1. By providing a plurality of grate bars on the support beam, the plurality of grate bars and the trolley body form a sealed first cavity. Similarly, a sealed second cavity is provided inside the side plate at the top of the trolley side wall. During the sintering process, the temperature at the bottom of the grate bars is usually the highest, but the temperature of the side plate is relatively lower than that at the bottom of the grate bars, and the sintering effect of the sintered material near the side plate is not good. By setting up an air bridge pipe, the thermal energy in the first cavity at the bottom of the grate bars is smoothly transferred to the second cavity in the side plate. In the sealed space, at the initial stage of sintering, the temperature of the first cavity is higher than that of the second cavity, and the heat is transferred to the second cavity through the air bridge pipe; at the later stage of sintering, the cold air is introduced through the flow guide nozzles to maintain the temperature balance. Through the air bridge pipe, the thermal energy transfer between the first cavity and the second cavity is realized, so that while the weight of the side plate is reduced, the heat preservation effect is improved by using the thermal energy transfer between the first cavity and the second cavity, replacing the super-thick material layer heat preservation scheme.

[0029] 2. A plurality of flow guide nozzles penetrate through the second cavity on the outer sides of the two side plates. The flow guide nozzles can pour the external cold air into the second cavity. When the wheels drive the trolley body to move, the flow guide nozzles continuously introduce cold air, so that the thermal energy of the first cavity continuously supplements the second cavity to maintain the temperature balance.

[0030] 3. The air bridge pipe is fixed on the first positioning bolts at the bottom of the trolley body and the trolley side wall through a plurality of first through holes at both ends, and is fastened by first nuts, which is convenient for disassembly. At the same time, dust-proof grilles are respectively arranged at both ends of the air bridge pipe. The dust-proof grilles effectively block dust. Separation plates are arranged at the bottoms of the two side plates. The separation plates can effectively isolate the thermal energy from the cold air, ensure that the thermal energy will not leak out, and ensure the efficiency and quality of the sintering process.

[0031] 4. Slide rails are arranged at the bottoms of the side plates, chutes corresponding to the slide rails are arranged on the trolley side wall, and positioning blocks are arranged at the ends of the slide rails. When installing the side plates, through the matching assembly of the slide rails at the bottoms of the side plates and the chutes, the side plates can slide along the chutes. When the slide rails reach the ends of the chutes, the positioning holes also enter the installation grooves. The second positioning bolts are threadedly assembled into the second through holes, and then the second nuts are tightened for fastening. The side plates are firmly fixed at the top of the trolley side wall, and then it is convenient to position the side plates for installation.

[0032] 5. A plurality of connecting beams are arranged in the second cavity inside the two side plates. Second reinforcing ribs are arranged between the plurality of connecting beams to fix the structural stability of the second cavity and maintain the stability of the side plates. At the same time, the inner walls of the side plates are designed in an arc shape, which is convenient for the uniform distribution of materials during material loading, reduces the stacking dead corners, and at the same time, the arc shape is more conducive to the circulation of hot air flow and improves the heat exchange efficiency.

[0033] 6. There are multiple third positioning bolts on the top cover. The side rail is fixed to the top cover through multiple third through holes on the inner side and tightened with third nuts. When in actual use, if more materials need to be loaded, the loading capacity can be increased by installing the side rail. Brief Description of the Drawings

Support feet 13 are provided at both sides of the trolley body 1, and the other ends of the support feet 13 are connected to the vehicle side wall 18 to enhance the overall strength of the trolley body 1.

[0067] A sintering machine trolley and its processing method include the following steps:

[0068] S1. Installation: Align the slide rails 21 at the bottom of the side plate 19 with the sliding grooves 16 for assembly. When the slide rails 21 reach the end of the sliding grooves 16, the positioning blocks 22 are inserted into the installation grooves 17 accordingly. The second through holes 28 on the side plate 19 and the vehicle side wall 18 correspond to each other. Thread the second positioning bolts 29 into the second through holes 28, and then tighten the second nuts 30 for fastening, so that the side plate 19 is firmly fixed on the top of the vehicle side wall 18.

[0069] Thread the first through holes 9 at both ends of the air bridge pipe 8 onto the first positioning bolts 10, and tighten the first nuts 11 for fastening to ensure a stable connection.

[0070] S2. Connection: When there is too much sintered material, thread a plurality of third through holes 34 inside the side rail 33 onto the third positioning bolts 35, and fix the third nuts 36 for fastening.

[0071] S3. Heat preservation: During the sintering process, the temperature of the first cavity 5 at the bottom of the grate bar 4 is the highest, and the temperature of the second cavity 20 provided inside the side plate 19 is relatively low. Thermal energy enters the air bridge pipe 8 through a plurality of first openings 6. The air bridge pipe 8 transfers the thermal energy to the second opening 7, and then the thermal energy enters the second cavity 20, enhancing the internal temperature of the second cavity 20 to achieve uniform distribution of heat between the trolley body 1 and the side plate 19. When the sintering trolley moves horizontally, the diversion nozzles 31 will continuously introduce external cold air into the second cavity 20, so that the thermal energy in the first cavity 5 always flows to the second cavity 20.

[0072] S4. Filtration: During the sintering process, the dust-proof grille 12 prevents dust from entering. When the sintering trolley is ignited and heated, a plurality of ignition ports 32 on the top cover 27 introduce high temperature into the second cavity 20. The second cavity 20 transfers the high temperature to the first cavity 5 through a plurality of air bridge pipes 8 to improve the sintering efficiency. The separation plate 23 at the bottom of the side plate 19 isolates the thermal energy from the cold air, separating the cold air, so as to keep the temperatures of the trolley body 1 and the two side plates 19 uniform all the time for efficient sintering.

[0073] The principle of the present invention is as follows: When the wheel 15 connected inside the reinforced bearing 14 drives the trolley body 1 to start firing, high temperature will enter the second cavity 20 through the ignition port 32. At this time, the temperature of the first cavity 5 is relatively low, and the thermal energy is quickly transferred to the first cavity 5 through the air bridge pipe 8 and quickly enters the sintering state. When the trolley body 1 is moving, the temperature of the side plate 19 gradually decreases. At this time, the temperature of the first cavity 5 below the grate bar 4 is relatively high, and the thermal energy is transferred into the second cavity 20 through the air bridge pipe 8. While the trolley body 1 is moving, a plurality of diversion nozzles 31 continuously introduce cold air to keep the thermal energy in the first cavity 5 always flowing towards the second cavity 20, ensuring heat balance and improving the sintering efficiency.

[0074] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features.

9. A sintering machine trolley and its processing method, characterized in that Applied to a sintering machine trolley described in claim 6, comprising the following steps: S1. Installation: Align the slide rails at the bottom of the side plate with the chute for assembly. When the slide rails reach the end of the chute, the positioning blocks are inserted into the installation grooves accordingly. The second through holes on the side plate correspond to those on the vehicle side panel. Thread the second positioning bolts into the second through holes, and then tighten the second nuts for fastening. The side plate is firmly fixed to the top of the vehicle side panel. Thread the first through holes at both ends of the air bridge pipe onto the first positioning bolts, and tighten the first nuts to ensure a secure connection. S2. Connection: When there is too much sintered material, thread multiple third through holes on the inner side of the side rail onto the third positioning bolts, and fix the third nuts for fastening. S3. Heat preservation: During the sintering process, the temperature of the first cavity at the bottom of the grate bar is the highest, and the temperature of the second cavity inside the side plate is relatively low. Thermal energy enters the air bridge pipe through multiple first openings. The air bridge pipe transfers the thermal energy to the second openings, and then the thermal energy enters the second cavity, enhancing the internal temperature of the second cavity and achieving uniform heat distribution between the trolley body and the side plate. When the sintering trolley moves horizontally, the deflector nozzle continuously introduces external cold air into the second cavity, causing the thermal energy in the first cavity to always flow towards the second cavity. S4. Filtration: During the sintering process, the dust-proof grille prevents dust from entering. When the sintering trolley is ignited and heated, multiple ignition openings on the top of the top cover allow high temperature to enter the second cavity. The second cavity transfers the high temperature to the first cavity through multiple air bridge pipes, improving the sintering efficiency. The separation plate at the bottom of the side plate isolates the thermal energy from the cold air, separating the cold air, thereby keeping the temperature of the trolley body and the two side plates always uniform for efficient sintering.
