Description

Technical Field

[0001] This invention relates to the field of sintering machine technology, and in particular to a high-efficiency and energy-saving sintering machine based on heat recycling. Background Technology

[0002] Sintering machines are suitable for sintering operations in large-scale ferrous metallurgical sintering plants. They are mainly used in large and medium-sized sintering plants for sintering iron ore powder. It is the main equipment in the exhaust sintering process and can sinter concentrate powder and rich ore powder of different compositions and 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 with different lengths and widths according to the sintering area. Users can choose according to their output or site conditions. The larger the sintering area, the higher the output.

[0003] However, in the existing technology, during the sintering process, after the sintered ore is heated by ignition and combustion, it will be cooled by air blowing in the cooling chamber. During the air cooling process, a large amount of high-temperature waste gas is generated. This waste gas usually carries a lot of sensible heat. Traditional sintering machines usually directly discharge this part of high-temperature waste gas into the atmosphere, which causes energy waste and increases environmental pollution.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0016] 1. The present invention, through the set circulation structure, can convert the high-temperature exhaust gas generated by cooling into high-temperature air, and then use the high-temperature air to perform a preliminary heating operation on the conveyed material, thereby reducing the subsequent sintering time of the material. This converts the high-temperature exhaust gas into heat recycling, avoids the direct discharge of high-temperature exhaust gas and its impact on the environment, reduces the energy consumption of the sintering machine, and improves the practicality of the sintering machine.

[0017] 2. The rotating plate drives the fixed column to make a circular motion, which in turn drives the moving frame on the outside of the fixed column to move back and forth left and right. This, in turn, drives the connecting plate and the cleaning brush plate on one side to move back and forth left and right, so that the cleaning brush plate can clean the surface of the filter plate repeatedly, thus preventing the filter plate from becoming clogged after long-term use.

[0018] 3. The cleaning structure can sweep off some raw materials or other impurities that are stuck to the surface of the conveyor plate after sintering when the sintering machine is conveying, so as to ensure that there will be no accumulation of raw materials or mixing of other impurities when feeding materials in the future.

[0019] 4. Through the transmission structure, the transport force of the sintering machine can be transmitted to the first gear. When the sintering machine is transporting, the second and third gears will rotate accordingly. Then, through the first and second connecting shafts respectively, the cleaning brush plate and the cleaning roller will move and rotate. This effectively reduces the power source required by the structure, greatly reduces the structural cost of the sintering machine, and improves the performance of the sintering machine.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1

[0039] like Figure 1-11As shown, the present invention provides a technical solution: a high-efficiency and energy-saving sintering machine based on thermal recycling, comprising: a support frame 11, a sintering chamber 17 and a cooling chamber 110 fixedly installed on the top of the support frame 11, an igniter 18 fixedly installed on the top of the sintering chamber 17, a cooler 111 fixedly installed on the top of the cooling chamber 110, a plurality of output ports 19 fixedly installed on the inner side of the sintering chamber 17, the igniter 18 and the plurality of output ports 19 being connected, a circulation structure 2 is provided on one side of the support frame 11, the circulation structure 2 including a filter box 21, two suction pipes 25 fixedly installed on one side of the filter box 21, and two... One end of an air intake pipe 25 passes through one side of the cooling chamber 110 and is fixedly connected to the cooling chamber 110. A fixing plate 23 is fixedly installed inside the filter box 21, and a filter plate 24 is fixedly installed on the top of the fixing plate 23. Two conveying pipes 22 are fixedly installed on the top of the filter box 21. One end of each conveying pipe 22 passes through one side of the sintering chamber 17 and is fixedly installed with an air outlet 28. A ventilation box 26 is fixedly installed between the two conveying pipes 22 and the sintering chamber 17. A blower 27 is fixedly installed on the top of the ventilation box 26. A cleaning structure 3 is provided on one side of the filter box 21, and two air outlets 28 are fixedly installed inside the support frame 11. A fixed inner ring 12 and two fixed outer rings 13 are provided. Several movable wheels 14 are rotatably arranged between the two fixed inner rings 12 and the two fixed outer rings 13. Each side of the movable wheels 14 is rotatably connected to a side plate 15. The side plates 15 are arranged in pairs, and a conveyor plate 16 is fixedly installed between each pair of side plates 15. Roller grooves 112 are provided on one side of each of the two fixed inner rings 12 and the two fixed outer rings 13. The movable wheels 14 are respectively located inside the four roller grooves 112 and roll in contact with the two fixed inner rings 12 and the two fixed outer rings 13. A fixed bracket 1 is provided at the bottom of the support frame 11. 14. A fixed bracket 114 is fixedly installed on the ground. A rotating shaft 115 is rotatably installed on the inner side of the fixed bracket 114. Two outer discs 116 are fixedly installed on the outer side of the rotating shaft 115. Several pushing blocks 117 are fixedly installed on the outer side of each of the two outer discs 116. An arc-shaped through groove 113 is opened on one side of each of the two fixed inner rings 12. Several pushing blocks 117 are respectively set on the inner side of the two arc-shaped through grooves 113 and do not contact the two fixed inner rings 12. A motor 118 is fixedly installed on one side of the fixed bracket 114. The output end of the motor 118 passes through one side of the fixed bracket 114 and is fixedly connected to the rotating shaft 115.

[0040] In this embodiment, the roller groove 112 formed by the fixed inner ring 12 and the fixed outer ring 13 facilitates the movement and limiting of the moving wheel 14 on one side of the side plate 15, ensuring stable movement during material conveying. The arc-shaped through groove 113 allows the push block 117 on the outer side of the outer disk 116 to pass through and enter the inner side of the roller groove 112. Thus, when the push blocks 117 rotate, they can move the moving wheel 14 on one side of the side plate 15. Since the side plates 15 and the conveyor plate 16 are designed to be tightly attached, when one is pushed to move, the other side plates 15 and the conveyor plate 16 will move under the action of force. This drives the overall conveying operation. The blower 27 absorbs the high-temperature exhaust gas generated inside the cooling chamber 110 through the conveying pipe 22, filter box 21, and suction pipe 25. Then, it is effectively filtered by the filter plate 24, purifying the exhaust gas and converting it into high-temperature air. This air is then discharged through the air outlet 28, thus providing preliminary high-temperature heating treatment to the conveyed materials. This reduces the sintering time of the materials and converts the high-temperature exhaust gas into heat recycling, avoiding the direct discharge of high-temperature exhaust gas and its impact on the environment. It also reduces the energy consumption of the sintering machine and improves its practicality.

[0041] Example 2

[0042] like Figure 1 and 8 As shown in Figure -11, the cleaning structure 3 includes a horizontal plate 31, which is fixedly installed on one side of the filter housing 21. A rotating plate 32 is rotatably installed on one side of the horizontal plate 31. A fixing column 33 is fixedly installed on one side of the rotating plate 32. A movable frame 34 is provided on the outer side of the fixing column 33. A connecting plate 35 is fixedly installed on one side of the movable frame 34. One side of the connecting plate 35 passes through one side of the filter housing 21 and slides in contact with the filter housing 21. A cleaning brush plate 36 is fixedly installed on one side of the connecting plate 35. 36 is located on one side of the filter plate 24. A collection frame 37 is provided on the inner side of the filter box 21. A vertical slide groove 38 is provided on one side of the filter box 21. A sealing plate 39 is slidably provided on the inner side of the vertical slide groove 38. A handle 310 is fixedly installed on one side of the sealing plate 39. Vertical plates 311 are fixedly installed on both sides of the sealing plate 39. Limiting slide grooves 312 are provided on both sides of the vertical slide groove 38. The two vertical plates 311 are respectively located on the inner side of the two limiting slide grooves 312 and slide in contact with the filter box 21.

[0043] In this embodiment, the movable frame 34 is a hollow rectangular frame design. When the rotating plate 32 rotates, causing the fixed column 33 to move in a circular motion, the fixed column 33 slides inside the movable frame 34, thereby driving the movable frame 34 to perform a corresponding reciprocating linear motion. This causes the connecting plate 35 and its cleaning brush 36 on one side to move accordingly. The cleaning brush 36, located on one side of the filter plate 24, can effectively clean the surface of the filter plate 24 during movement, sweeping some impurities and dust filtered by the filter plate 24 from one side of the filter plate 24 into the collection frame 37 for collection. This effectively prevents excessive accumulation of impurities on the surface of the filter plate 24 after prolonged use. In the event of blockage affecting use, the connecting plate 35, which extends through one side of the filter housing 21 and slides in contact with the filter housing 21, effectively limits the movement of the connecting plate 35. This ensures that when the fixed column 33 makes a circular motion, it can only drive the connecting plate 35 and the moving frame 34 to move back and forth left and right, and cannot make any additional movement, thus ensuring the stability of the structure. The two vertical plates 311 and the two limiting grooves 312 work together to effectively seal the opening of the filter housing 21 on the one hand, and effectively limit the sealing plate 39 on the other hand, ensuring that the sealing plate 39 can only move in the vertical direction and preventing the sealing plate 39 from falling off.

[0044] Example 3

[0045] like Figure 1 , 2As shown in Figure 11, a cleaning structure 4 is provided at the bottom of the support frame 11. The cleaning structure 4 includes a U-shaped frame 41, which is fixedly installed at the bottom of the support frame 11. Two upright plates 42 are fixedly installed at the top of the U-shaped frame 41. A cleaning roller 43 is rotatably installed between the two upright plates 42. A transmission structure 5 is provided between the horizontal plate 31 and the U-shaped frame 41. Two first-order synchronous pulleys 44 are rotatably installed on one side of one of the upright plates 42. A first-order synchronous belt 45 is sleeved on the outer side of the two first-order synchronous pulleys 44. The two first-order synchronous pulleys 44 are connected by transmission through the first-order synchronous belt 45. One end of one of the first-order synchronous pulleys 44 passes through one of the upright plates 42 and is fixedly connected to the cleaning roller 43. The transmission structure 5 includes a support plate 51, which is fixedly installed on the ground. A second-order synchronous pulley 52 is rotatably installed on one side of both the support plate 51 and the fixed bracket 114. A second-order synchronous pulley 53 is sleeved on the outer side of the two second-order synchronous pulleys 52. A synchronous belt 53 connects two No. 2 synchronous pulleys 52. One end of one No. 2 synchronous pulley 52 passes through one side of the fixed bracket 114 and is fixedly connected to the rotating shaft 115. A No. 1 gear 54 is rotatably mounted on the other side of the support plate 51. One end of the other No. 2 synchronous pulley 52 passes through the support plate 51 and is fixedly connected to the No. 1 gear 55 and No. 3 gear 56 are rotatably mounted on one side of the support plate 51. The No. 1 gear 54 and the No. 2 gear 55 are meshed together, as are the No. 2 gear 55 and the No. 3 gear 56. A No. 1 connecting shaft 57 is fixedly mounted on one side of the No. 2 gear 55. One end of the No. 1 connecting shaft 57 passes through the horizontal plate 31 and is fixedly connected to the rotating plate 32. A No. 2 connecting shaft 58 is fixedly mounted on one side of the No. 3 gear 56. One end of the No. 2 connecting shaft 58 passes through the support plate 51 and one side of the U-shaped frame 41 and is fixedly connected to the other No. 1 synchronous pulley 44.

[0046] In this embodiment, the cleaning roller 43 is located at the bottom inner side of the support frame 11, and the moving frame 34 is in contact with the surfaces of several conveying platforms 16 below. This allows it to sweep away raw materials or other impurities that are stuck to the surface of the conveying platforms 16 after sintering during the conveying process of the sintering machine. This ensures that there will be no accumulation of raw materials or mixing of other impurities during subsequent feeding. The two second-stage synchronous pulleys 52 and the second-stage synchronous belt 53 can transmit the conveying force of the sintering machine to the first gear 54. As a result, the second gear 55 and the third gear 56 will rotate during the sintering process, and then drive the cleaning brush plate 36 and the cleaning roller 43 to move and rotate through the first connecting shaft 57 and the second connecting shaft 58, respectively. This effectively reduces the power source required for the structure, significantly reduces the structural cost of the sintering machine, and improves the performance of the sintering machine.

[0047] Working principle:

[0048] like Figure 1-11As shown, during use, the material is poured onto the conveyor plate 16 located on one side, and then the motor 118 is started. The specific model of the motor 118 is not described, but is based on the compatible equipment. The motor 118 will drive the rotating shaft 115 to rotate, thereby driving the two outer discs 116 and several pushing blocks 117 on their outer sides to rotate, pushing the moving wheels 14 on one side of several side plates 15, thereby driving several conveyor plates 16 to perform transmission and transportation. The material on the conveyor plate 16 will first pass through the sintering chamber 17. Inside the sintering chamber 17, the igniter 18 will use heat to sinter the material at high temperature through the output port 19. The sintered material will continue to be transported and then pass through the cooling chamber 110. Under the action of the air cooler 111, the material will be cooled, thereby completing the cooling operation. Then it will be transported to one side of the conveyor plate 16 and fall down for collection and further processing.

[0049] During the cooling process, the high-temperature material generates a lot of high-temperature exhaust gas. Then, the blower 27 is started, and the high-temperature exhaust gas inside the cooling chamber 110 is sucked in and transported through two conveying pipes 22, the filter box 21, and two suction pipes 25. When the high-temperature exhaust gas is transported to the filter box 21, it passes through the filter plate 24 inside the filter box 21. At this time, some impurities and harmful substances in the high-temperature exhaust gas are blocked by the filter plate 24, so that the high-temperature exhaust gas passing through the filter plate 24 is converted into high-temperature air. Finally, it is transported through the two conveying pipes 22 to the air outlet 28 inside the sintering chamber 17 for discharge. In this way, the transported material is initially heated by the high-temperature air, so that the subsequent sintering time of the material is reduced. This converts the high-temperature exhaust gas into heat recycling, avoids the direct discharge of high-temperature exhaust gas and its impact on the environment, reduces the energy consumption of the sintering machine, and improves the practicality of the sintering machine.

[0050] During the conveying process, the rotating shaft 115 drives one of the second synchronous pulleys 52 to rotate, which in turn drives the other second synchronous pulley 52 to rotate via the second synchronous belt 53. This drives the first gear 54 to rotate, which in turn drives the second gear 55 to mesh and rotate, causing the third gear 56 to mesh and rotate. The second gear 55 drives the rotating plate 32 to rotate via the first connecting shaft 57, causing the fixed column 33 to rotate in a circular motion and drive the moving frame 34 to move back and forth. This causes the connecting plate 35 and the cleaning brush plate 36 on one side to move back and forth, allowing the cleaning brush plate 36 to clean the surface of the filter plate 24 repeatedly, preventing the filter plate 24 from becoming clogged after prolonged use. At the same time, the third gear 56 drives the second connecting shaft 58 to rotate, which drives one of the first synchronous pulleys 44 to rotate. This drives the other first synchronous pulley 44 to rotate via the first synchronous belt 45, causing the cleaning roller 43 to rotate. This effectively cleans the surface of the conveying platform 16 through which the material is circulated, improving the performance of the sintering machine.

[0051] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
