Description

Technical Field

[0001] The invention relates to the technical field of cement preparation, in particular to a method for preparing multi-component cement. Background Art

[0002] Multi-component cement is a powdery hydraulic inorganic gelling material, which becomes a slurry after adding water and stirring. It can harden in the air or in water, and can firmly bond sand, stone and other materials together to form a solid wall. The production of cement can generally be divided into the processes of raw material transportation and preparation, clinker calcination, cement grinding and packaging.

[0003] When cement raw materials are made into raw meal, it is usually necessary to transport the various raw materials with the completed proportions to the grinding equipment through a belt conveyor, and then crush and grind them into cement raw meal. When cement raw materials are transported by belt conveyors, since multi-component cement has more components than ordinary cement, different raw materials need to be transported in batches.

[0004] However, when conveying cement raw materials, belt conveyors usually need to be equipped with iron removers. The iron impurities in the raw materials transported on the belt are removed by the iron remover to ensure the safety of the roller press itself when the subsequent roller press grinds the raw materials. Therefore, when transporting each raw material in batches, in order to ensure that the iron remover can effectively remove iron, the transportation speed should not be too fast. Batch transportation will increase the transportation time, which will in turn affect the overall preparation process of multi-component cement. Summary of the invention

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1:

[0035] See also Figure 1-10 , a method for preparing multi-component cement, characterized in that it comprises the following steps:

[0036] S1: According to the weight of cement produced according to construction requirements, select limestone, clay and sandstone with corresponding proportions as main raw materials, wherein the proportions of each raw material are limestone 60%±5%, clay 15%±5%, sandstone 15%±5%, and then these cement raw materials are transported to the grinding mill through a belt conveyor for grinding, and then according to the construction requirements, select an appropriate amount of slag fly ash 5%±5% as auxiliary material, and these main raw materials are homogenized by dry grinding to make cement raw materials;

[0037] S2: transporting the prepared cement raw material to a wet process kiln for wet calcination;

[0038] S3: The prepared cement clinker is transported into a roller press, ground to the required particle size, and then stored in a clinker warehouse. Then, the slag fly ash in S1 is proportioned to the cement clinker using a clinker microcomputer batching system, and 5%±5% of natural gypsum is added. Then, after the cement clinker is homogenized, the cement is packaged using a packaging machine and stored in a warehouse.

[0039] The belt conveyor in S1 includes a conveyor body 1 and a controller. A three-pronged channel 11 is fixed inside the vertical entrance of the conveyor body 1. A short-distance conveying belt 12 is fixed inside the three-pronged channel 11. An iron remover 13 is fixed on the top of the three-pronged channel 11. The short-distance conveying belt 12 and the iron remover 13 are controlled by the controller. A collecting frame 14 is fixed outside the three-pronged channel 11 below the iron remover 13.

[0040] A long-distance conveying belt 2 is fixed inside the horizontal part of the conveyor body 1, and the long-distance conveying belt 2 is controlled by a controller. A mounting frame 3 is fixed inside the vertical part of the conveyor body 1, and a driving motor 31 is fixed outside the vertical part of the conveyor body 1. The driving motor 31 is controlled by a controller, and the output shaft of the driving motor 31 is located inside the mounting frame 3. A bevel gear plate 32 is fixed outside the output shaft of the driving motor 31, and a connecting rod 33 is fixed outside the bevel gear plate 32. A first fan blade 34 is fixed outside the end of the connecting rod 33 away from the driving motor 31. A filter plate 35 is fixed inside the mounting frame 3, and a dust collecting frame 36 is slidably connected to the inner side of the mounting frame 3 and the filter plate 35. A mixing component is provided inside the horizontal part of the conveyor body 1, and the mixing component is used to mix cement raw materials;

[0041] The mixing assembly includes a rotating shaft 4, which is rotatably connected to the conveyor body 1, a rotating rod 41 is fixed to the bottom of the rotating shaft 4, a bevel gear ring 42 is fixed to the outside of the rotating rod 41, the bevel gear ring 42 is meshed with the bevel gear plate 32, a stirring rod 43 is fixed to the bottom of the rotating rod 41, and the bottom of the stirring rod 43 contacts the top of the long-distance conveying belt 2;

[0042] During the specific operation, firstly, each raw material required for the multi-component cement is put into the inside of the three-pronged channel 11 respectively, and each short-distance conveying belt 12 is started by the controller, and each cement raw material is conveyed by the short-distance conveying belt 12. During the cement raw material conveying process, when the cement raw material passes under the iron remover 13, each iron remover 13 is started by the controller. After the iron remover 13 is started, the iron impurities in the cement raw material below it are conventionally adsorbed by the iron remover 13. After the preliminary iron removal, each cement raw material is continuously conveyed to the inside of the conveyor body 1 by the short-distance conveying belt 12, and finally falls on the top of the long-distance conveying belt 2. After the long-distance conveying belt 2 is started by the controller, each cement raw material is continuously conveyed by the long-distance conveying belt 2, thereby enabling the device to convey multiple raw materials in the same batch, thereby increasing the amount of raw materials conveyed at a single time, and thereby improving the overall process of multi-component cement preparation;

[0043] Furthermore, when the short-distance conveying belt 12 conveys each cement raw material into the interior of the conveyor body 1, due to the height difference between the short-distance conveying belt 12 and the long-distance conveying belt 2, each cement raw material falls on the top of the long-distance conveying belt 2, generating dust. In this process, the driving motor 31 is started by the controller, and the driving motor 31 drives the bevel gear plate 32 to rotate, and the bevel gear plate 32 drives the connecting rod 33 and the first fan blade 34 to rotate. During the rotation process, the first fan blade 34 has the effect of exhausting air, and then collects the dust generated during the transportation of the cement raw materials into the interior of the dust collecting frame 36. When the dust collecting frame 36 needs to be cleaned, the dust collecting frame 36 can be lifted out of the mounting frame 3 and the interior of the conveyor body 1 through the handle provided on the top of the dust collecting frame 36 for cleaning, thereby improving the convenience of cleaning the dust collecting frame 36, thereby reducing the impact of dust on the surrounding air, and improving the efficiency of environmental protection.

[0044] Furthermore, when the driving motor 31 is started, the bevel gear plate 32 rotates synchronously with the driving motor 31, and then the bevel gear ring 42 is driven by the bevel gear plate 32 to rotate synchronously. During the rotation process, the bevel gear ring 42 drives the rotating rod 41 to rotate synchronously, and the rotating rod 41 drives the stirring rod 43 to rotate synchronously. When the long-distance conveying belt 2 transports each cement raw material in a centralized manner, the cement raw material passes through the stirring rod 43;

[0045] When the cement raw material passes through the stirring rod 43, the rotating stirring rod 43 pre-crushes the cement raw material, so that raw materials with poor hardness such as clay can be pre-crushed into smaller blocks or particles, thereby reducing the workload of grinding in subsequent cement preparation. At the same time, the volumes of the pre-crushed raw materials are more uniform and close, so that the pressures of the raw materials on the long-distance conveying belt 2 tend to be the same, avoiding excessive local pressure differences caused by large-volume and small-volume raw materials on the long-distance conveying belt 2, resulting in poor belt tension, thereby increasing the service life of the long-distance conveying belt 2;

[0046] At the same time, the stirring rod 43 can stir and mix the various cement raw materials during the rotation process, so that the various cement raw materials can complete the preliminary mixing, that is, the preliminary homogenization operation is performed on the various cement raw materials, thereby reducing the market for homogenizing the various cement raw materials in the subsequent grinding process, and further improving the efficiency of multi-component cement preparation.

[0047] Embodiment 2:

[0048] A touch rod 5 is slidably connected to the top of the horizontal part of the conveyor body 1, a cross rod 51 is fixed to the top of the touch rod 5, a first spring 52 is fixed to the bottom of the cross rod 51 near the rotating shaft 4, and the first spring 52 is fixed to the conveyor body 1, and a vibration rod 53 is fixed to the bottom of the two sides and the middle of the cross rod 51, and the vibration rod 53 passes through the top of the horizontal part of the conveyor body 1. The outside of the vibration rod 53 is slidably connected to a limit plate 54, and a second spring 55 is fixed to the top of the limit plate 54, and the second spring 55 is fixed to the conveyor body 1;

[0049] Built-in grooves 6 are provided on both sides of the horizontal part of the conveyor body 1, wherein a primary bevel gear 61 is rotatably connected to the top of the inner cavity of one of the built-in grooves 6, the primary bevel gear 61 passes through the conveyor body 1 and meshes with the bevel gear ring 42, a secondary bevel gear 62 is fixed to the bottom of the primary bevel gear 61, a transmission gear 63 is rotatably connected to the inner wall of one side of the built-in groove 6, the transmission gear 63 meshes with the secondary bevel gear 62, a connecting rod 64 is fixed to the outside of the transmission gear 63 near the side of the secondary bevel gear 62, and the outside of the connecting rod 64 is transmission-connected to the first belt 65;

[0050] The horizontal part of the conveyor body 1 is internally rotatably connected with a transmission rod 66, and one end of the transmission rod 66 away from the first belt 65 is fixed with a support shaft 67, the transmission rod 66 is in transmission connection with the first belt 65, and a four-point electromagnet 68 is fixed outside the support shaft 67, and the four-point electromagnet 68 is controlled by a controller;

[0051] A lead screw 7 is rotatably connected to the inside of the built-in groove 6 away from the primary bevel gear 61, and a hexagonal handle 71 is fixed to the outside of the end of the lead screw 7 away from the drive motor 31. A sliding groove 72 is provided on the inner wall of the built-in groove 6 close to the long-distance conveying belt 2. A linkage plate 73 is threadedly connected to the outside of the lead screw 7, and the linkage plate 73 is slidably connected to the sliding groove 72. A sliding frame 74 is fixed to the outside of the linkage plate 73 close to the end of the primary bevel gear 61, and one end of the sliding frame 74 is in contact with the four-part electromagnet 68. A scraper 75 is fixed to the lower part of the outside of the sliding frame 74, and a leakage groove 76 is provided on the surface of the scraper 75, and the scraper 75 is in contact with the four-part electromagnet 68.

[0052] During the specific operation, the cement raw materials after preliminary crushing and processing are continuously moved toward the direction of the four-point electromagnet 68 under the transportation of the long-distance conveying belt 2. During this process, the driving motor 31 drives the bevel gear plate 32 to drive the bevel gear ring 42 to rotate, and the bevel gear ring 42 drives the rotating rod 41 to rotate synchronously. During the rotation process, the rotating rod 41 repeatedly contacts the touch rod 5. After contacting the rotating rod 41, the touch rod 5 is repeatedly ejected and moved. During the movement process, the touch rod 5 drives the cross rod 51 to move synchronously. During the displacement process, the cross rod 51 drives the vibration rod 53 to move synchronously. During the movement process, the cross rod 51 is subjected to the reaction force of the first spring 52, so that the touch rod 5 is repeatedly ejected and recovered inside the top end of the horizontal part of the conveyor body 1, and then the touch rod 5 drives the cross rod 51 and the vibration rod 53 to be repeatedly ejected and recovered inside the conveyor body 1.

[0053] During the process of repeated ejection and recovery, the vibration rod 53 repeatedly contacts the long-distance conveying belt 2, thereby playing the role of vibrating the long-distance conveying belt 2, so that the pre-crushed and mixed cement raw materials can be vibrated, and then the cement raw materials on the top of the long-distance conveying belt 2 can be laid more evenly, and the cement raw materials are more loose, thereby avoiding the cement raw materials from stacking.

[0054] At the same time, when the cement raw material passes under the limiting plate 54, the limiting plate 54 is used to smooth and lay the cement raw material, so that the cement raw material on the top of the long-distance conveying belt 2 is laid more evenly, and then the pressure on the long-distance conveying belt 2 is more even, thereby further improving the service life of the long-distance conveying belt 2;

[0055] Further, after the driving motor 31 is started, the driving motor 31 drives the bevel gear plate 32 to drive the bevel gear ring 42 to rotate, and the bevel gear ring 42 drives the primary bevel gear 61 to rotate synchronously, the primary bevel gear 61 drives the secondary bevel gear 62 to rotate, the secondary bevel gear 62 drives the transmission gear 63 to rotate, the transmission gear 63 drives the linkage rod 64 to rotate, and then drives the first belt 65 through the linkage rod 64, and the first belt 65 drives the transmission rod 66 to rotate, and the transmission rod 66 drives the support shaft 67 and the four-point electromagnet 68 to rotate;

[0056] When the cement raw materials with more uniform distribution continue to move toward the quartered electromagnet 68 following the long-distance conveyor belt 2, until the cement raw materials pass under the quartered electromagnet 68, the controller starts each quartered electromagnet 68 at this time, so that the rotating quartered electromagnet 68 performs secondary iron removal operation on the cement raw materials. Since each raw material is not broken when being transported by the short-distance conveyor belt 12, and in the case of stacking, some iron impurities are covered and contained, and cannot be completely removed by the iron remover 13;

[0057] Under the action of the rotation of the stirring rod 43, the iron impurities contained between or inside the raw materials are further exposed, and under the action of the vibration rod 53 vibrating the cement raw materials, the exposure of the iron impurities in the cement raw materials is further enhanced. Then, with the activation of the four-point electromagnet 68, the iron impurities in the cement raw materials can be further removed by suction, thereby improving the efficiency of the subsequent multi-component cement preparation and the life of the subsequent roller press during grinding.

[0058] Furthermore, when the four-part electromagnet 68 rotates to a side close to the long-distance conveyor belt 2, the iron impurities can be adsorbed. When the four-part electromagnet 68 adsorbing the iron impurities rotates to a side close to the sliding frame 74, the controller controls the power of the individual four-part electromagnet 68 to be cut off, so that a four-part electromagnet 68 close to the sliding frame 74 loses its magnetic force, and then the iron impurities adsorbed on the surface of the current four-part electromagnet 68 fall into the interior of the sliding frame 74, thereby playing the role of collecting the iron impurities on the surface of the four-part electromagnet 68, and continuing the iron removal operation later;

[0059] When the iron impurities collected inside the sliding frame 74 need to be removed, the hexagonal handle 71 can be rotated to drive the lead screw 7 to rotate, and then the transmission linkage plate 73 and the sliding frame 74 move inside the conveyor body 1 and the sliding groove 72, and then the sliding frame 74 is detached from the inside of the conveyor body 1, and then the sliding frame 74 is taken out and cleaned.

[0060] It should be noted that the diameter of the lead screw 7 is larger than the diameter of the hexagonal handle 71, thereby ensuring that the linkage plate 73 can be detached from the outside of the lead screw 7. As for the four-part electromagnet 68, the four-part electromagnet 68 is divided into four equal parts, and each part of the four-part electromagnet 68 is independently controlled by the controller. The power-off operation of the four-part electromagnet 68 can be set according to the actual rotation speed of the four-part electromagnet 68, so that each part of the four-part electromagnet 68 can be powered off within a specified time period, and then demagnetized to complete the removal of iron impurities.

[0061] At the same time, in order to ensure the efficiency of meshing transmission, all the gears in the present invention are uniform bevel gears.

[0062] Embodiment three:

[0063] The external transmission of the rotating shaft 4 is connected with the second belt 8, the internal rotation of the top of the horizontal part of the conveyor body 1 is connected with the transmission shaft 81, and the transmission shaft 81 is connected with the second belt 8, the bottom of the transmission shaft 81 is fixed with the second blade 82, the top of the cross rod 51 close to the transmission shaft 81 is fixed with a U-shaped rod 83, the bottom of one end of the U-shaped rod 83 is fixed with a pressure plate 84, and the bottom of the pressure plate 84 is fixed with a sealing gasket 85;

[0064] A water tank 9 is fixed on the top of the horizontal part of the conveyor body 1, a nozzle 91 is fixed on the top of the horizontal part of the conveyor body 1, and the nozzle 91 and the water tank 9 are connected to each other, a cover 92 is fixed inside the top of the water tank 9, the cover 92 is slidably connected to the U-shaped rod 83, and a sealing gasket 85 is located inside the connection between the nozzle 91 and the water tank 9;

[0065] Specifically, on the basis of the first embodiment, when the driving motor 31 is started, the driving motor 31 drives the bevel gear plate 32 to drive the bevel gear ring 42 to rotate synchronously, and the bevel gear ring 42 drives the rotating rod 41 and the rotating shaft 4 to rotate synchronously, and then drives the second belt 8 to rotate through the rotating shaft 4, and drives the transmission shaft 81 to rotate through the second belt 8, and then the transmission shaft 81 drives the second blade 82 to rotate, and the second blade 82 generates wind during the rotation process, and blows toward the four-part electromagnet 68, thereby performing air cooling operation on the four-part electromagnet 68 through the second blade 82, thereby playing the role of heat dissipation of the four-part electromagnet 68, and further improving the efficiency of secondary iron removal of the four-part electromagnet 68;

[0066] At the same time, based on the second embodiment, when the rotating rod 41 is rotating and performing an ejection operation on the touch rod 5, the touch rod 5 drives the cross rod 51 to repeatedly eject and recover the top of the horizontal part of the conveyor body 1, and during the repeated ejection and recovery operation of the cross rod 51, the cross rod 51 drives the U-shaped rod 83 to be ejected and recovered synchronously, and then the U-shaped rod 83 is repeatedly ejected and recovered inside the cover 92;

[0067] When the U-shaped rod 83 is repeatedly pushed out and recovered inside the cover 92, the U-shaped rod 83 drives the pressure plate 84 and the sealing gasket 85 to repeatedly block the connection between the water tank 9 and the nozzle 91, thereby making the nozzle 91 and the water tank 9 in a process of repeated connection. When the nozzle 91 and the water tank 9 are connected, the clean water in the water tank 9 can be sprayed into the interior of the conveyor body 1 through the nozzle 91, and the cement raw materials on the top of the long-distance conveying belt 2 are dusted, further reducing the dust generated during the transportation of the cement raw materials, thereby improving the environmental protection of the present invention when used;

[0068] At the same time, since the nozzle 91 is located above the second blade 82, when the nozzle 91 sprays, the rotating second blade 82 can further enhance the spraying range of the clean water, thereby enhancing the efficiency of the clean water dust reduction. At the same time, the rotating second blade 82 can guide the water mist and water flow of the clean water to the surface of the four-point electromagnet 68, and the four-point electromagnet 68 is water-cooled by the water mist or water flow, further improving the heat dissipation efficiency and iron removal efficiency of the four-point electromagnet 68.

[0069] And by spraying clean water, when the clean water comes into contact with the clay in the cement raw materials, it can reduce the hardness of the clay, making the clay softened, and then improve the grinding efficiency of the subsequent roller press;

[0070] Furthermore, when the water mist comes into contact with the dust, part of it adheres to the surface of the four-part electromagnet 68. When the rotating four-part electromagnet 68 comes into contact with the scraper 75, the condensate on the surface of the four-part electromagnet 68 is scraped off by the scraper 75, thereby ensuring the iron removal efficiency of the four-part electromagnet 68. The scraped condensate can pass through the leakage groove 76 and fall back into the cement raw material on the top of the long-distance conveyor belt 2. Since the dust itself comes from each cement raw material, when the dust re-condenses into blocks, it can continue to be used as a cement raw material, which can reduce the consumption of cement raw materials. Subsequently, the mixed cement raw materials are transported to subsequent preparation equipment through the long-distance conveyor belt 2.
