Description
Technical Field
[0001] The present invention relates to the technical field of cement, and particularly relates to a steel slag-ferrite cement and its production device. Background Art
[0002] Ferrite cement has high early strength, good frost resistance, corrosion resistance and wear resistance, and is commonly used in emergency repair projects, marine engineering, etc. The preparation process of ferrite cement mainly includes steps such as raw material preparation, mixing and homogenization, high-temperature calcination and grinding. Specifically:
[0003] Raw material preparation: Select high-quality ferro-aluminous bauxite and other necessary auxiliary raw materials such as limestone, gypsum, etc.
[0004] Mixing and homogenization: Mix the high-quality ferro-aluminous bauxite and other raw materials in a certain proportion and mix them evenly to ensure the uniformity of the mineral composition of the cement clinker.
[0005] High-temperature calcination: Feed the evenly mixed raw materials into a high-temperature kiln for calcination to form cement clinker with a specific mineral composition. The calcination temperature and time need to be adjusted according to the raw material characteristics and the target mineral composition.
[0006] Grinding: Grind the calcined cement clinker to increase its specific surface area and activity, facilitating subsequent hydration reactions and engineering applications.
[0007] However, with the increasingly scarce high-quality bauxite resources in China and the continuous decrease in the grade of high-quality ferro-aluminous bauxite, the production cost of ferrite cement is getting higher and higher, seriously restricting the production and application of energy-saving and low-carbon ferrite cement industry.
[0008] Steel slag is an industrial solid waste formed in the metallurgical industry, and its effective components are iron oxide, aluminum oxide and calcium oxide. Due to the presence of free calcium oxide and magnesium oxide, the steel slag has problems of poor soundness. The current national standard "Common Portland Cement" GB 175 clearly prohibits the use of steel slag as a blending material to produce Portland cement, seriously restricting the resource utilization of steel slag in the cement industry.
[0009] During the process of cement production, it is necessary to mix and grind the raw materials to obtain cement products; a cement production mixing device with the publication number of CN113198367A in the prior art includes a mixing tank, a centrifugal screening mesh, a screening mesh driving component, a conveying component, a stirring and mixing component and a screening mesh flapping anti-blocking component. The screening mesh driving component is arranged on the top wall of the mixing tank, a guide plate is arranged in the middle of the mixing pipe, the guide plate is arranged in a funnel-shaped structure, a material guiding port is arranged at the lowest position of the guide plate, the guide plate divides the mixing tank into a screening cavity and a mixing cavity, the centrifugal screening mesh, the conveying component and the screening mesh flapping anti-blocking component are all arranged in the screening cavity, the stirring and mixing component is arranged in the mixing cavity, and a discharge port is arranged on the bottom wall of the mixing tank.
[0010] The deficiencies of the above prior art are as follows. On the one hand, the iron and aluminum materials for the production of ferroaluminate cement, namely high-iron bauxite, are in short supply and their grade has decreased, which restricts the production and application of ferroaluminate cement. And due to the soundness and standard problems, the steel slag containing effective components of iron oxide, aluminum oxide and calcium oxide cannot be effectively recycled; on the other hand, the prior art can only mix and screen cement raw materials, while the grinding of raw materials requires additional equipment for processing, increasing the cost of cement production, and the need to transfer raw materials, etc., reducing the efficiency of cement production. Therefore, this application proposes a steel slag-ferroaluminate cement and its production device. Summary of the Invention
[0011] The purpose of the present invention is to solve the above technical problems and propose a steel slag-ferroaluminate cement and its production device.

[0016] An adjustable grinding mechanism; the grinding mechanism is installed inside the cylindrical screen. During the grinding process of the raw materials by the grinding mechanism, the grinding particle size can be adjusted, and the raw materials can be gradually broken to gradually reduce the particle size and ground.
[0017] Preferably, two rotating rods are rotatably arranged through the two brackets, and two driving wheels are installed on each of the two rotating rods. Two driven rings are fixed on the outer wall of the mixing cylinder, and the driving wheels are arranged in cooperation with the driven rings.
[0018] Preferably, the grinding mechanism includes two installation grooves arranged through both ends of the mixing cylinder. A circular plate is rotatably connected in the installation groove. A through groove is provided through the circular plate. Two I-shaped blocks that are slidably connected are buckled in the through groove. A driving rod is rotatably arranged through the two I-shaped blocks in the axial direction of the mixing cylinder, and a grinding roller is installed on the driving rod.
[0019] Preferably, it further includes a driving mechanism capable of driving the two grinding rollers to rotate. The driving mechanism includes a motor installed on the bracket. The output end of the motor is fixedly connected with a power rod. A first fixing block is fixed on the circular plate. A rotationally arranged cylinder penetrates through the first fixing block. First bevel gears are installed on both the cylinder and the power rod. The two first bevel gears are meshed with each other. Second fixing blocks are fixed on both I-shaped blocks close to the first bevel gears. A first sleeve tube rotatably connected thereto penetrates through the second fixing block. Second bevel gears are installed on both the first sleeve tube and the driving rod. The two second bevel gears are meshed with each other. The inner part of the first sleeve tube is rectangular in shape. A first rectangular rod is slidably connected in the first sleeve tube. The first rectangular rod is fixedly connected with the cylinder.
[0020] Preferably, it further includes two transmission mechanisms capable of driving the two grinding rollers to move synchronously. The transmission mechanisms include a first reciprocating lead screw and a second reciprocating lead screw that penetrate through the bracket and are rotatably connected thereto. The first reciprocating lead screw and the second reciprocating lead screw penetrate through the I-shaped blocks on the same side and are in mating connection therewith. The first reciprocating lead screw is fixedly connected with the second reciprocating lead screw. A second sleeve tube rotatably arranged penetrates through the bracket. The inner part of the second sleeve tube is rectangular in shape. A second rectangular rod is slidably connected in the second sleeve tube. The second rectangular rod is fixedly connected coaxially with the second bevel gear. A first transmission wheel and a second transmission wheel are respectively fixedly connected to the second reciprocating lead screw and the second sleeve tube. The first transmission wheel and the second transmission wheel are connected by a first transmission belt.
[0021] Preferably, it further includes a linkage mechanism capable of driving the rotating rod to rotate. The linkage mechanism includes a support block fixed on the bracket.

[0025] 3. The distance between the two grinding rollers changes accordingly, providing space for the raw materials that cannot be broken so that the raw materials can be processed by the grinding rollers for crushing and grinding. Due to the continuous rotation of the cylindrical screen, the raw materials can be continuously conveyed into the grinding rollers, and the raw materials can be ground in a cyclic manner.
[0026] 4. The rotating cylindrical screen can also screen the ground raw materials. The raw materials passing through the cylindrical screen fall into the mixing cylinder, and the raw materials that cannot pass through the cylindrical screen are ground cyclically until they can pass through the cylindrical screen to ensure the quality of cement processing.
[0027] 5. The raw materials are reciprocally conveyed between the two grinding rollers, which also causes the raw materials to turn and mix with each other. After grinding, the mixing effect of the raw materials is better and more sufficient. Then, they fall into the rotating mixing cylinder to further mix the ground raw materials, thereby ensuring the quality of cement.
[0028] In summary, when the motor of the present invention works, the two grinding rollers move and rotate synchronously, and the rotation of the cylindrical screen can be realized. The raw materials can be crushed and ground, and the crushed raw materials can be screened and mixed, which can ensure the quality of the produced cement and avoid the disadvantages of the prior art that additional equipment is required to cooperate to realize cement production, resulting in low production efficiency and increased production costs.

Detailed implementation manners
[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.
[0038] In view of the problems that the steel slag has poor soundness, the national standard prohibits the use of steel slag as a blending material for the production of portland cement, and how to maximize the digestion and utilization of steel slag on the premise of ensuring strength and safety, the present invention proposes a steel slag-ferroaluminate cement, and the steel slag-ferroaluminate cement includes the following raw materials: clinker, steel slag, gypsum and limestone. The clinker, steel slag, gypsum and limestone are mixed and ground through a production device to form the steel slag-ferroaluminate cement. Among them, the main components of the clinker are anhydrous calcium sulfoaluminate, calcium ferrite and dicalcium silicate.
[0039] Specifically: Raw material preparation: Select qualified steel slag (maximum incorporation of steel slag) and other necessary auxiliary raw materials, such as limestone, gypsum, etc.; Mixing and homogenization: Mix the steel slag and other raw materials evenly according to a certain ratio to ensure the uniformity of the mineral composition of the cement clinker; High-temperature calcination: Feed the evenly mixed raw meal into a high-temperature kiln for calcination to form a cement clinker with a specific mineral composition. The calcination temperature and time need to be adjusted according to the raw material characteristics and the target mineral composition. Grinding: Grind the calcined cement clinker to increase its specific surface area and activity, facilitate subsequent hydration reactions and engineering applications, solve the problems of steel slag soundness and inability to be applied on a large scale in the cement industry, and realize the resource utilization of bulk solid wastes.
[0040] Refer to Figures 1-7, the present invention also discloses a production device for steel slag-ferroaluminate cement, including two brackets 1. A mixing cylinder 2 capable of being driven to rotate is provided on the two brackets 1. A discharge port may penetrate through the mixing cylinder 2, and the discharge port is blocked by a baffle. A feeding port penetrates through one side of the mixing cylinder 2 so as to add raw materials into the cylindrical screen 27; wherein, the feeding port, the discharge port and the baffle are not shown in the figure; a cylindrical screen 27 is fixedly connected inside the mixing cylinder 2, and a plurality of guide plates 28 are fixedly connected to the cylindrical screen 27; two rotating rods 4 rotatably arranged penetrate through the two brackets 1, and two driving wheels 5 are installed on each of the two rotating rods 4. Two driven rings 3 are fixed on the outer wall of the mixing cylinder 2, and the driving wheels 5 and the driven rings 3 are arranged in cooperation. Among them, the driving wheel 5 may be a driving gear, and the driven ring 3 is a toothed ring, and the toothed ring is fixed on the outside of the mixing cylinder 2.
[0041] An adjustable grinding mechanism; the grinding mechanism is installed inside the cylindrical screen 27. During the process of grinding the raw materials by the grinding mechanism, the grinding particle size can be adjusted, and the raw materials can be gradually broken to make the particle size gradually decrease and be ground.
[0042] A further detailed explanation of the grinding mechanism: The grinding mechanism includes two installation grooves 29 penetrating through both ends of the mixing cylinder 2. A circular plate 11 is rotatably connected in the installation grooves 29. A through groove 16 penetrates through the circular plate 11. Two I-shaped blocks 20 connected in a sliding manner are buckled in the through groove 16. The groove bodies on the I-shaped blocks are in sliding contact with the side walls of the circular plate 11. In this way, the I-shaped blocks 20 are buckled on the circular plate 11, so that the I-shaped blocks 20 slide stably on the circular plate 11; A driving rod 26 rotatably arranged penetrates through the two I-shaped blocks 20 along the axial direction of the mixing cylinder 2, and a grinding roller 25 is installed on the driving rod 26.
[0043] It also includes a driving mechanism capable of driving the two grinding rollers 25 to rotate. The driving mechanism includes a motor 6 installed on the bracket 1. The output end of the motor 6 is fixedly connected with a power rod 7. A first fixing block 17 is fixed on the circular plate 11. A cylinder 24 rotatably arranged penetrates through the first fixing block 17. First bevel gears 18 are installed on both the cylinder 24 and the power rod 7, and the two first bevel gears 18 are meshed with each other. Second fixing blocks 22 are fixed on the two I-shaped blocks 20 close to the first bevel gear 18. A first sleeve 19 rotatably connected therewith penetrates through the second fixing blocks 22. Second bevel gears 21 are installed on both the first sleeve 19 and the driving rod 26, and the two second bevel gears 21 are meshed with each other. The inside of the first sleeve 19 is rectangular in shape. A first rectangular rod 23 is slidably connected inside the first sleeve 19, and the first rectangular rod 23 is fixedly connected with the cylinder 24. In this way, the first rectangular rod 23 can rotate and slide between the first sleeve 19.
[0044] It further includes two transmission mechanisms capable of driving the two grinding rollers 25 to move synchronously. The transmission mechanisms include a first reciprocating lead screw 13 and a second reciprocating lead screw 14 that penetrate through the bracket 1 and are rotatably connected thereto. The first reciprocating lead screw 13 and the second reciprocating lead screw 14 penetrate through the same-side I-shaped block 20 and are cooperatively connected thereto. The first reciprocating lead screw 13 is fixedly connected to the second reciprocating lead screw 14. The bracket 1 is provided with a rotatably arranged second sleeve 31 in a penetrating manner. The inside of the second sleeve 31 is rectangular in shape. A second rectangular rod 30 is slidably connected inside the second sleeve 31. The second rectangular rod 30 is coaxially and fixedly connected to the second bevel gear 21. A first transmission wheel 32 and a second transmission wheel 33 are respectively fixedly connected to the second reciprocating lead screw 14 and the second sleeve 31. The first transmission wheel 32 is connected to the second transmission wheel 33 through a first transmission belt 34. The diameter of the first transmission wheel 32 is larger than that of the second transmission wheel 33, so as to achieve the function of speed reduction through transmission.
[0045] It further includes a linkage mechanism capable of driving the rotating rod 4 to rotate. The linkage mechanism includes a support block 8 fixed on the bracket 1. The support block 8 is provided with a rotatably arranged transmission rod 12 in a penetrating manner. Third bevel gears 9 are fixedly arranged on both the transmission rod 12 and the rotating rod 4. The two third bevel gears 9 are meshed with each other. Third transmission wheels 15 are fixedly arranged on both the transmission rod 12 and the first reciprocating lead screw 13. The two third transmission wheels 15 are connected through a second transmission belt 10.
[0046] When the present invention is used, raw materials are added into the cylindrical screen 27 through the feeding port, and then the motor 6 is started;
[0047] The motor 6 works to drive the power rod 7 to rotate. The rotation of the power rod 7 drives the first bevel gear 18 to rotate. The rotation of the first bevel gear 18 drives the cylinder 24 to rotate. The rotation of the cylinder 24 drives the two first rectangular rods 23 to rotate. The rotation of the first rectangular rods 23 drives the first sleeve 19 and the second bevel gear 21 to rotate. Through the transmission of the two second bevel gears 21, the driving rod 26 can be driven to rotate. The rotation of the driving rod 26 drives the grinding roller 25 to rotate;
[0048] The rotation of the second bevel gear 21 drives the second rectangular rod 30 and the second sleeve 31 to rotate. The rotation of the second sleeve 31 drives the second transmission wheel 33 to rotate. Under the transmission of the first transmission belt 34, the first transmission wheel 32 rotates, and then the second reciprocating lead screw 14 rotates. The rotation of the second reciprocating lead screw 14 drives the first reciprocating lead screw 13 to rotate. Since the I-shaped block 20 cannot rotate in the through groove 16, when the first reciprocating lead screw 13 and the second reciprocating lead screw 14 rotate, the two I-shaped blocks 20 can move relatively, thereby driving the driving rod 26 and the grinding roller 25 to move, so that the two grinding rollers 25 move relatively;
[0049] The rotation of the first reciprocating screw 13 drives the third transmission wheel 15 to rotate. Under the transmission of the second transmission belt 10, the transmission rod 12 is rotated, and the rotation of the transmission rod 12 drives the third bevel gear 9 to rotate. The rotation of the rotating rod 4 is driven by the two third bevel gears 9. The rotation of the rotating rod 4 drives the driving wheel 5 to rotate. The rotation of the driving wheel 5 drives the driven ring 3 and the mixing drum 2 to rotate. The rotation of the mixing drum 2 drives the cylindrical screen 27 to rotate. The rotation of the cylindrical screen 27 drives the guide plate 28 to rotate. The rotation of the guide plate 28 drives the raw material to rotate. When the guide plate 28 and the raw material move to the upper side, the raw material at this time separates from the guide plate 28 due to gravity, and is guided by the guide plate 28 and falls between the two grinding rollers 25. The rotation of the two grinding rollers 25 can squeeze and crush the fallen raw material.
[0050] Among them, through the rotation of the rotating rod 4 and the two third bevel gears 9, the first reciprocating screw 13 and the second reciprocating screw 14 away from the motor 6 can be rotated, so as to achieve the synchronous movement of the I-shaped blocks 20 at both ends, so that the grinding roller 25 can move more stably, and the crushing and grinding of the raw materials can be more stable; when the two grinding rollers 25 move, the first sleeve 19 and the first rectangular rod 23 slide relative to each other;
[0051] It should be noted that the rotation of the first reciprocating screw 13 and the second reciprocating screw 14 causes the two grinding rollers 25 to move relative to each other and then move back to each other, and so on; when the two grinding rollers 25 move relative to each other, the distance between the two grinding rollers 25 decreases, so that the particle size of the raw material can be changed, but as the first reciprocating screw 13 and the second reciprocating screw 14 rotate, the two grinding rollers 25 separate again, so that the distance between the two grinding rollers 25 increases; because when the guide plate 28 pours the material and falls between the two grinding rollers 25, the raw material will collide with the grinding rollers 25, so that not all of the raw materials fall between the two grinding rollers 25. If the two grinding rollers 25 are only continuously reduced, part of the raw materials will not be ground and crushed by the grinding rollers 25, resulting in a reduction in the effect of grinding the raw materials. Since part of the raw materials cannot be ground into powder, the quality of cement is also reduced.
[0052] Therefore, the distance between the two grinding rollers 25 changes accordingly, which can provide space for the raw materials that cannot be crushed, so that the raw materials can be processed, crushed and ground by the grinding rollers 25; due to the continuous rotation of the cylindrical screen 27, the raw materials can be continuously transported to the grinding rollers 25, and the raw materials can be ground repeatedly;
[0053] The rotating cylindrical screen 27 can also screen the ground raw materials, and the raw materials passing through the cylindrical screen 27 fall into the mixing drum 2 and are temporarily stored through the mixing drum 2;
[0054] In addition, reciprocally conveying the raw materials between the two grinding rollers 25 also causes the raw materials to be turned and mixed, and after grinding, the mixing effect between the raw materials is better and more sufficient. Then, the materials fall into the rotating mixing cylinder 2, further mixing the ground raw materials, so as to ensure the quality of the cement.
[0055] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
