Description

Technical Field

[0001] This invention relates to the field of metallurgical technology, specifically to a high-efficiency and energy-saving sintering machine for pretreatment of low-grade antimony ore. Background Technology

[0002] Antimony ore refers to antimony mining areas that have industrial value and are suitable for current beneficiation and smelting conditions. There are only 10 antimony minerals with an antimony content of more than 20%, among which stibnite is the most important mineral raw material for antimony beneficiation and smelting.

[0003] The processing of antimony ore typically includes crushing, screening, beneficiation (such as flotation), and smelting. Sintering generally occurs during the pretreatment stage before smelting, and its core objectives are: 1. To increase ore grade: Sintering removes impurities (such as sulfur and arsenic), improving the purity of the antimony concentrate. 2. To improve physical properties: Sintering powdered or fine-grained antimony ore into lumps enhances permeability, facilitating subsequent smelting (such as blast furnace smelting). 3. To remove harmful components: During sintering, some harmful elements such as sulfur and arsenic can volatilize, reducing pollution and equipment corrosion during smelting.

[0004] The existing technology has the following problems: Since low-grade antimony ore is often accompanied by high clay content or fine-grained impurities, the existing single-stage conveyor belt or transfer equipment is prone to adhesion and bridging phenomena during long-distance transportation due to uneven material moisture and large particle size differences. Especially at turns or drop ports, blockages are formed, requiring frequent shutdowns for cleaning, which seriously reduces the continuity of production. Summary of the Invention

[0005] To address the aforementioned technical problems, a high-efficiency and energy-saving sintering machine for pre-treatment of low-grade antimony ore is provided. This solves the problem that, in existing technologies, single-stage conveyor belts or transfer equipment are prone to adhesion and bridging phenomena during long-distance transportation due to uneven material moisture and large particle size differences, especially at bends or discharge points, where blockages occur, requiring frequent shutdowns for cleaning and severely reducing production continuity.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

A fine grinding component is located below the end of the second conveyor belt away from the primary crushing component. A third rotating shaft is located below the fine grinding component. A third conveyor belt is fitted with the outer surface of the third rotating shaft. A packing component is located on the left side of the fine grinding component. Several gas supply pipes are located above the third conveyor belt and are linearly distributed along the edge of the third conveyor belt. Several flame guns are fixedly installed on the outer surface of the gas supply pipes and are linearly distributed along the axial direction of the gas supply pipes.

[0008] Preferably, the preliminary crushing component includes two first side plates, each fixedly connected to a support plate. A fixing plate is fixedly installed below the first conveyor belt, and the fixing plate is fixedly connected to both first side plates. A cam is provided between the two first side plates corresponding to the fixing plate, and the cam is rotatably connected to the two first side plates. A bushing is fitted on the outer surface of the cam, and a pressing plate corresponding to the fixing plate is fitted on the outer surface of the bushing. A base plate is fixedly installed on one side of each of the two first side plates corresponding to the pressing plate. A guide rod is fixedly installed on the side of the base plate closest to the pressing plate, and a spring is fitted on the outer surface of the guide rod. The two ends of the spring are fixedly connected to the base plate and the pressing plate, respectively.

[0009] Preferably, the fine grinding assembly includes a second side plate, and two second side plates are provided. A first guide plate and a second guide plate are provided between the two second side plates. The first guide plate and the second guide plate are both connected to the two second side plate fixing plates. The first guide plate abuts against the second conveyor belt. Two crushing wheels are provided between the first guide plate and the second guide plate. Two gears are provided on the side of the second side plate corresponding to the crushing wheel. The two gears mesh with each other, and the gears are fixedly connected to the corresponding crushing wheels.

[0010] Preferably, the packing assembly includes a third side plate, and two third side plates are provided. Two lead screws are provided between the two third side plates, and both lead screws are rotatably connected to the two third side plates. A sliding plate is provided between the two third side plates, and the sliding plate is threadedly connected to both lead screws. A connecting pipe is fixedly installed on the bottom surface of the sliding plate. The connecting pipe abuts against the third conveyor belt. A conical plate is fixedly installed on the side of the connecting pipe near the fine grinding assembly, and a discharge chute is opened on the side of the connecting pipe away from the conical plate.

[0011] Preferably, the third side plate corresponding to the lead screw is provided with two rollers, the two rollers correspond one-to-one with the two lead screws, and the rollers are fixedly connected to the corresponding lead screws. The outer surfaces of the two rollers are fitted with a first synchronous belt.

[0012] Preferably, a first adjusting plate is provided between the grinding component and the packing component, and a second adjusting plate is provided between the packing component and the flame tube.

[0013] Preferably, the side of the support plate corresponding to the first rotating shaft is provided with a plurality of connecting shafts, and the plurality of connecting shafts correspond one-to-one with the first rotating shaft, the second rotating shaft and the third rotating shaft, and the outer surfaces of two connecting shafts that are close to each other are fitted with a second synchronous belt.

[0015] Preferably, a storage box is fixedly installed on the upper surface of the fixing plate.

[0016] Compared with the prior art, the advantages of the present invention are as follows: The present invention uses a conveying pipe and a spray pipe to clean the antimony ore by spraying high-speed water. The high-speed water flow removes high clay content or fine-grained impurities from the surface of the antimony ore and keeps the moisture content of the antimony ore consistent. This removes small-particle impurities, prevents adhesion and bridging, and improves the overall cleanliness of the equipment. At the same time, the wet antimony ore produces less dust after crushing, further improving the cleanliness of the equipment.

[0017] This invention incorporates a preliminary crushing component and a fine grinding component. The preliminary crushing component crushes large pieces of antimony ore into small pieces, while the fine grinding component crushes the small pieces into antimony ore powder. Through two-stage crushing, the antimony ore is pulverized into antimony ore powder, thereby improving the stability of the antimony ore powder and ensuring the stability of the product after sintering.

[0018] This invention incorporates a packing assembly. The screw within the packing assembly works in conjunction with a third conveyor belt to create a sinusoidal curve in the combustion-supporting agent on the third conveyor belt. The rotational speed of the third conveyor belt is constant. By controlling the rotational speed and direction of the screw, the amount of combustion-supporting agent filled into the antimony ore powder is controlled, thereby controlling the sintering effect of the antimony ore powder.

[0032] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0033] Reference Figures 1-6 As shown, a high-efficiency and energy-saving sintering machine for pre-treatment of low-grade antimony ore includes a support plate 1. Two support plates 1 are provided. A first rotating shaft 2 is rotatably mounted on one side of the two support plates 1 that is close to each other. A first conveyor belt 3 is sleeved on the outer surface of the first rotating shaft 2. Several conveying pipes 4 are arranged above the first conveyor belt 3, linearly distributed along the edge of the first conveyor belt 3. Several nozzles 5 are connected to the outer surface of the conveying pipes 4, linearly distributed along the axial direction of the conveying pipes 4. A preliminary crushing component 6 is arranged below the first conveyor belt 3. A second rotating shaft 7 is located below the primary crushing component 6. A second conveyor belt 8 is fitted onto the outer surface of the second rotating shaft 7. A fine grinding component 9 is located below the end of the second conveyor belt 8 furthest from the primary crushing component 6. A third rotating shaft 10 is located below the fine grinding component 9. A third conveyor belt 11 is fitted onto the outer surface of the third rotating shaft 10. A packing component 12 is located on the left side of the fine grinding component 9. Several air supply pipes 13 are located above the third conveyor belt 11. The air supply pipes 13 are linearly distributed along the edge of the third conveyor belt 11. Several flame guns 14 are fixedly installed on the surface, linearly distributed along the axial direction of the gas supply pipe 13. Workers place low-grade antimony ore onto the surface of the first conveyor belt 3. The first rotating shaft 2 rotates, causing the first conveyor belt 3 to move the low-grade antimony ore. Simultaneously, high-speed water flows sequentially through the conveyor pipe 4 and the nozzle 5 to clean the surface of the low-grade antimony ore of loose soil. Several channels are provided on the outer surface of the first conveyor belt 3, linearly distributed along the edge of the first conveyor belt 3. The muddy water containing loose soil leaves the equipment through the channels, completing the cleaning process. Antimony ore falls into the primary crushing component 6. The moist antimony ore can effectively suppress the generation of dust during the crushing process. The pre-crushed antimony ore falls onto the surface of the second conveyor belt 8. The second rotating shaft 7 rotates, causing the second conveyor belt 8 to carry a large number of small pieces of antimony ore into the fine grinding component 9. The fine grinding component 9 performs secondary crushing on the small pieces of antimony ore to reduce the particle size of the antimony ore powder. The antimony ore powder enters the surface of the third conveyor belt 11. The filling component 12 fills the antimony ore powder with combustion aid (combustion aid includes coke and coal powder). The flame gun 14 performs sintering treatment on the antimony ore powder.

[0034] like Figure 4As shown, the preliminary crushing component 6 includes two first side plates 601, each fixedly connected to a support plate 1. A fixing plate 602 is fixedly installed below the first conveyor belt 3, and is fixedly connected to both first side plates 601. A cam 603 is provided between the two first side plates 601 corresponding to the fixing plate 602, and is rotatably connected to the two first side plates 601. A bushing 604 is fitted on the outer surface of the cam 603, and a pressing plate 605 corresponding to the fixing plate 602 is fitted on the outer surface of the bushing 604. A base plate 606 is fixedly installed on the side of the two first side plates 601 corresponding to the pressing plate 605, close to each other. A guide rod 607 is fixedly installed on the side of the base plate 606 close to the pressing plate 605, and a spring 608 is fitted on the outer surface of the guide rod 607. The two ends of the spring 608 are fixedly connected to the base plate 606 and the pressing plate 605, respectively. The working principle of the preliminary crushing component 6 is that of a jaw crusher. A transmission wheel is provided on the side of the first side plate 601 corresponding to the cam 603. The transmission wheel is fixedly connected to the cam 603 and is connected to the output end of the servo motor through a transmission belt. The cam 603 and the bushing 604 form an eccentric wheel. The transmission wheel drives the cam 603 to rotate. The cam 603 and the bushing 604 drive the extrusion plate 605 to reciprocate. When the long shaft end of the cam 603 approaches the fixed plate 602, the extrusion plate 605 compresses the spring 608 and approaches the fixed plate 602. The antimony ore is crushed by the extrusion plate 605 and the fixed plate 602. When the short shaft end of the cam 603 moves away from the fixed plate 602, the spring 608 releases its elastic potential energy and pushes the extrusion plate 605 to reset. The antimony ore between the extrusion plate 605 and the fixed plate 602 moves downward. The extrusion plate 605 and the fixed plate 602 form a conical space. As the antimony ore moves downward, it is gradually compressed into small pieces of antimony ore.

[0035] like Figure 5As shown, the fine grinding assembly 9 includes two second side plates 901. A first guide plate 902 and a second guide plate 903 are disposed between the two second side plates 901. Both the first guide plate 902 and the second guide plate 903 are connected to the fixing plates 602 of the two second side plates 901. The first guide plate 902 abuts against the second conveyor belt 8. Two crushing wheels 904 are disposed between the first guide plate 902 and the second guide plate 903. Two gears 905 are disposed on the side of the second side plate 901 corresponding to the crushing wheels 904. The two gears 905 mesh with each other, and the transmission ratio of the two gears 905 is 1. The gears 905 are fixedly connected to the corresponding crushing wheels 904. One of the crushing wheels 904 is connected to an external servo motor. The servo motor drives the crushing wheel 904 and the corresponding gear 905 to rotate. The gear 905 drives the other gear 905 to rotate, so that the two gears 905 rotate in opposite directions. This makes the two crushing wheels 904 rotate in opposite directions, so that the small pieces of antimony ore falling into the crushing wheel 904 move between the two crushing wheels 904, making it easier to crush the small pieces of antimony ore into antimony ore powder.

[0036] like Figure 6 As shown, the packing assembly 12 includes two third side plates 1201. Two lead screws 1202 are disposed between the two third side plates 1201, and both lead screws 1202 are rotatably connected to the two third side plates 1201. A sliding plate 1203 is disposed between the two third side plates 1201, and the sliding plate 1203 is threadedly connected to both lead screws 1202. A connecting pipe 1204 is fixedly installed on the bottom surface of the sliding plate 1203, and the connecting pipe 1204 abuts against the third conveyor belt 11. A conical plate 1205 is fixedly installed on the side of the connecting pipe 1204 near the fine grinding assembly 9. A discharge chute 1206 is provided on the side of 204 away from the conical plate 1205. The lead screw 1202 rotates repeatedly, causing the slider to reciprocate along the axial direction of the lead screw 1202. The combustion aid falls onto the surface of the third conveyor belt 11 through the connecting pipe 1204. The conical plate 1205 pushes the antimony powder on the third conveyor belt 11. The discharge chute 1206 facilitates the third conveyor belt 11 to carry the combustion aid away from the connecting pipe 1204. The lead screw 1202 and the third conveyor belt 11 cooperate to make the combustion aid form a sine curve on the third conveyor belt 11. A solenoid valve is provided in the connecting pipe 1204 to control the discharge of the combustion aid.

[0037] like Figure 6As shown, two rollers 15 are provided on the side of the third side plate 1201 corresponding to the lead screw 1202. The two rollers 15 correspond one-to-one with the two lead screws 1202, and the rollers 15 are fixedly connected to the corresponding lead screws 1202. The outer surfaces of the two rollers 15 are fitted with a first synchronous belt 16. One of the lead screws 1202 is connected to an external power source. The rollers 15 rotate in the same direction through the first synchronous belt 16, and realize the synchronous rotation of the two lead screws 1202. The two lead screws 1202 rotate in the same direction, ensuring the smoothness of the two lead screws 1202 pushing the slide plate 1203 to move.

[0038] like Figure 3 As shown, a first adjusting plate 17 is provided between the fine grinding component 9 and the packing component 12, and a second adjusting plate 18 is provided between the packing component 12 and the flame tube. When the antimony ore powder falls onto the surface of the third conveyor belt 11, a large amount of antimony ore powder accumulates. The first adjusting plate 17 flattens the antimony ore powder, making it easier for the packing component 12 to fill the antimony ore powder with the combustion aid. The second adjusting plate 18 flattens the combustion aid and the antimony ore powder.

[0039] like Figure 1 As shown, the side of the support plate 1 corresponding to the first rotating shaft 2 is provided with several connecting shafts 19. The several connecting shafts 19 correspond one-to-one with the first rotating shaft 2, the second rotating shaft 7 and the third rotating shaft 10. The outer surfaces of two connecting shafts 19 that are close to each other are fitted with a second synchronous belt 20. The second rotating shaft 7 is externally connected to a servo motor. The second rotating shaft 7 drives the corresponding connecting shaft 19 to rotate. The several connecting shafts 19 run synchronously through the second synchronous belt 20, so that the first rotating shaft 2, the second rotating shaft 7 and the third rotating shaft 10 rotate synchronously and at the same speed.

[0040] like Figures 1-3 As shown, a baffle 21 is provided above the end of the first conveyor belt 3 away from the primary crushing component 6. The baffle 21 abuts against the first conveyor belt 3. The baffle 21 and the first conveyor belt 3 cooperate with each other to prevent large pieces of antimony ore from rolling off after being placed. At the same time, the baffle 21 and the first conveyor belt 3 can form a storage cavity to store a certain amount of antimony ore.

[0041] like Figures 1-6 As shown, a storage box 22 is fixedly installed on the upper surface of the fixing plate 602. The storage box 22 is connected to the connecting pipe 1204, and the storage box 22 is convenient for storing combustion aid.

[0042] Working principle: Workers place low-grade antimony ore onto the surface of the first conveyor belt 3. The first rotating shaft 2 rotates, causing the first conveyor belt 3 to move the low-grade antimony ore. Simultaneously, high-speed water flows through the conveying pipe 4 and the spray pipe 5 to wash away the loose soil on the surface of the low-grade antimony ore. Several channels are provided on the outer surface of the first conveyor belt 3, linearly distributed along its edge. The muddy water containing loose soil exits the equipment through these channels. The washed antimony ore falls into the primary crushing component 6. The moist antimony ore effectively suppresses dust generation during the crushing process. The transmission wheel inside the preliminary crushing component 6 drives the cam 603 to rotate. The cam 603 and the bushing 604 drive the extrusion plate 605 to reciprocate. When the long shaft end of the cam 603 approaches the fixed plate 602, the extrusion plate 605 compresses the spring 608 and approaches the fixed plate 602. The antimony ore is crushed by the extrusion plate 605 and the fixed plate 602. When the short shaft end of the cam 603 moves away from the fixed plate 602, the spring 608 releases its elastic potential energy, pushing the extrusion plate 605 to return to its original position. The antimony ore between the extrusion plate 605 and the fixed plate 602 moves downward, and the extrusion plate 605 and the fixed plate 602 form a conical space. As the antimony ore descends, it is gradually compressed into smaller pieces. These pre-crushed pieces fall onto the surface of the second conveyor belt 8. The second rotating shaft 7 rotates, causing the second conveyor belt 8 to carry a large number of these smaller pieces into the fine grinding assembly 9. Inside the fine grinding assembly 9, gear 905 drives another gear 905 to rotate, resulting in opposite rotation directions for the two gears 905. This, in turn, causes the two crushing wheels 904 to rotate in opposite directions, moving the smaller pieces of antimony ore that fall into the crushing wheels 904 between them. This facilitates the crushing of the smaller pieces into antimony ore powder, achieving the desired fine grinding. The secondary crushing of antimony ore reduces the particle size of the antimony ore powder. The screw 1202 in the packing assembly 12 rotates repeatedly, causing the slider to reciprocate along the axial direction of the screw 1202. The combustion aid falls onto the surface of the third conveyor belt 11 through the connecting pipe 1204. The conical plate 1205 pushes the antimony ore powder on the third conveyor belt 11. The discharge chute 1206 facilitates the third conveyor belt 11 to carry the combustion aid away from the connecting pipe 1204. The screw 1202 and the third conveyor belt 11 cooperate to make the combustion aid form a sinusoidal curve on the third conveyor belt 11, thereby improving the combustion effect of the antimony ore powder.
