Description

Technical Field

[0001] The invention relates to the technical field of limestone transportation, and in particular to a fluidized limestone transportation device. Background Art

[0002] Fluidized limestone conveying device is a device that uses fluidization technology to make solid particles in a fluid-like state through gas to achieve efficient and stable conveying of limestone particles. It is widely used in chemical, electric power, metallurgy and other fields. Its core principle is to introduce compressed air into the conveying pipeline to make the limestone particles form a uniform suspended flow state under the action of airflow, thereby reducing conveying resistance, reducing pipeline wear, and achieving long-distance and large-flow conveying; Improper storage conditions of limestone, especially in the rainy season, can easily lead to an increase in the moisture content of the limestone, causing a sudden drop in particle fluidity, and even the formation of particle accumulation and inability to fluidize in the storage tank. If the moisture content of limestone is too high, the particles will easily stick together after absorbing water on the surface, destroying the uniformity of fluidization. The particle size distribution is uneven, and small particles fill the gaps between large particles, resulting in a decrease in air permeability and the formation of local dense phases or stratification.

When there are too many impurities remaining on the filter screen, the drive release component can release the positioning component from fixing the filter plate, and the filter plate can be pulled out at this time. The overall device is simple to use, easy to operate, and has a high degree of automation. It eliminates the need to dismantle the pipeline and has high safety. "The above patent document, although it can facilitate the disassembly and assembly of the filter plate, it is difficult to solve the problem that the limestone has a high moisture content and is easy to stick together, affecting the fluidization and conveying effect of the limestone.

At least two mounting seats 52 are fixed in the silo 1, and the heating rod 51 is fixed to the mounting seats 52. The limestone put into the silo 1 is subjected to primary heating treatment by the heating rod 51, thereby reducing the moisture content in the limestone. With the addition of the mounting seats 52, the stability of the heating rod 51 can be improved; It should be noted that the air compressor 6 does work on the air through a high-speed rotating impeller, generates high-pressure air flow by centrifugal force, and transports the high-pressure air flow to the inside of the conveying pipe 4, which is suitable for large-scale limestone conveying scenarios to achieve the fluidized conveying of limestone. This is a conventional setting in the field, so it will not be elaborated in detail here; It should also be noted that the limestone to be conveyed is put into the silo 1 by the feeding mechanism, and the limestone is screened by the screening unit 7. The limestone that does not meet the particle size requirements is put into the treatment box 8, and then the limestone that meets the particle size requirements falls into the conveying pipe 4. The limestone that does not meet the particle size requirements is crushed by the crushing mechanism 9, so as to reduce the particle size of the limestone, solve the problem of uneven particle size distribution of limestone particles, guide the limestone after pretreatment into the conveying pipe 4, and convey high-pressure air into the conveying pipe 4 through the air compressor 6, thereby completing the fluidized conveying of limestone.

[0027] Furthermore, the dust reduction mechanism 10 includes: a dust suction pump 53 is fixed on the silo 1, a pipeline a54 is fixed between the input end of the dust suction pump 53 and the silo 1 and is connected in communication, a pipeline b55 is fixed at the output end of the dust suction pump 53, a filter 56 is fixed on the silo 1, the other end of the pipeline b55 is docked with the filter 56, and a jet pipe 57 is fixed between the filter 56 and the silo 1 and is connected in communication. One end of the pipeline a54 located inside the silo 1 is fixed with a gas collecting pipe 58; Among them, the inner side wall of the silo 1 is arranged as an inclined surface, and the opening of the jet pipe 57 faces directly above the inclined surface of the inner side wall of the silo 1, so that the limestone on the inner side wall of the silo 1 can be smoothly blown into the conveying pipe 4, effectively improving the limestone conveying rate; It should be noted that through the setting of the dust reduction mechanism 10, the dust generated during the feeding process of the limestone put into the silo 1 can be efficiently absorbed, thereby effectively reducing the amount of dust generated by the limestone feeding operation and significantly improving the working environment. In addition, the dust reduction mechanism 10 can also finely filter the extracted air, remove the dust particles therein, ensure the cleanliness of the air, and after the filtered clean air is pressurized, it is sprayed to the bottom of the silo 1 to form a strong air flow, thereby effectively improving the fluidized conveying rate of the limestone in the silo 1 and ensuring that the limestone always maintains a normal fluidized state during the conveying process, avoiding affecting the production efficiency and product quality due to unsmooth conveying; The principle of absorbing the dust generated by the limestone feeding by using the dust reduction mechanism 10: driven by the dust suction pump 53, the dust generated by the feeding in the silo 1 is extracted by the pipeline a54 and the gas collecting pipe 58, and the extracted air is filtered by the filter 56. With the connection of the jet pipe 57, the clean high-pressure air can be sprayed into the silo 1; Further, the screening unit 7 includes: a sieve plate 24 slidably connected in the bin 1, at least two mounting sleeves 25 fixed in the bin 1. The side of the mounting sleeve 25 close to the bin 1 is provided with a chamfered inclined surface, which plays a role in guiding the limestone and prevents the limestone from staying on the mounting sleeve 25. A slider 26 slidably connected to the inside of the mounting sleeve 25 is fixed on the sieve plate 24. A spring a 27 is commonly fixed between the slider 26 and the mounting sleeve 25. A rotating shaft a 28 is rotatably connected in the bin 1, and a servo motor a 29 is fixed outside the bin 1. One end of the output shaft of the servo motor a 29 is coaxially fixed to the rotating shaft a 28. At least two cams 30 are fixed on the rotating shaft a 28. A through groove a 31 is commonly opened between the treatment box 8 and the bin 1. The sieve plate 24 extends into the treatment box 8. The included angle of the sieve plate 24 is set to be obtuse, ensuring that the limestone that does not meet the particle size requirements can smoothly enter the treatment box 8; Specifically, a baffle 59 is slidably connected in the bin 1, and the baffle 59 abuts against the sieve plate 24. An installation block 60 is fixed in the bin 1, and a spring piece 61 is commonly fixed between the installation block 60 and the baffle 59. By adding the baffle 59 and the spring piece 61, it can be ensured that the baffle 59 is always in a fitting state with the sieve plate 24, thereby preventing the limestone that meets the particle size requirements from falling into the treatment box 8 during the screening of the limestone; The principle of using the screening unit 7 to screen limestone: Driven by the servo motor a 29, the rotating shaft a 28 rotates synchronously, driving the cams 30 to rotate synchronously. By utilizing the extrusion transmission effect between the cams 30 and the sieve plate 24 and the elastic effect of the spring a 27, it can be ensured that the sieve plate 24 is always in a fitting state with the cams 30. By using the extrusion transmission effect between the cams 30 and the sieve plate 24, the sieve plate 24 can be driven to reciprocate up and down, realizing the purpose of screening large-particle-size limestone; In addition, the crushing mechanism 9 includes: at least two crushing rollers 32 are rotatably connected in the processing box 8, and a spur gear a 33 is fixed to one end of each of the two crushing rollers 32.

A servo motor b 38 is fixed to the mounting frame 37. One end of the output shaft of the servo motor b 38 is fixed to the rotating shaft b 36. An incomplete gear 39 is fixed to the rotating shaft b 36. A toothed ring 40 meshed with the incomplete gear 39 is fixed to the toothed plate 34. A through groove b 41 is formed between the processing box 8 and the storage bin 1. A blanking plate 42 is slidably connected in the processing box 8. One end of the blanking plate 42 extends into the storage bin 1 through the through groove b 41. A heating coil 43 is fixed in the processing box 8. A guiding plate 62 is fixed in the processing box 8. The guiding plate 62 and the crushing roller 32 are arranged obliquely. The side of the guiding plate 62 adjacent to the crushing roller 32 is arranged as a smooth arc surface. By adding the guiding plate 62, it is ensured that the limestone can be concentrated between the two crushing rollers 32, thereby effectively improving the crushing effect on the limestone; Specifically, a plate body is fixed to the processing box 8, and the toothed plate 34 is slidably penetrated through the plate body by a sliding rod, so as to play a role in guiding and limiting the toothed plate 34, ensuring that the toothed plate 34 can move up and down reciprocally in a relatively stable state; It should be noted that through the setting of the screening unit 7, accurate and effective jitter screening treatment can be carried out on the limestone particles. This process can not only effectively separate the limestone particles with larger particle sizes and prevent them from entering the conveying pipe 4 by mistake, but also fundamentally avoid problems such as poor fluidity and retention caused by large particle limestone entering the conveying pipe 4. It provides a guarantee for the smooth progress of the fluidized conveying work of limestone, ensuring that during the conveying process, the limestone particles can always be in a state with relatively consistent and uniform particle sizes, greatly improving the conveying efficiency and stability, and laying a good foundation for the reliable operation of the entire conveying system; It should also be noted that through the setting of the crushing mechanism 9, the large particle size limestone screened by the screening mechanism can be crushed, thereby reducing the particle size of the limestone. Moreover, the water content of the crushed limestone can be reduced, and the heating coil 43 is used to perform secondary heating and drying treatment on the limestone, effectively reducing the water content of the limestone, not only ensuring the fluidity of the limestone during transportation, but also effectively avoiding the problem that the limestone particles adhere to each other in groups after adsorbing water on the surface and destroying the fluidization uniformity; Principle of limestone crushing using the crushing unit: Driven by the servo motor b38, the rotating shaft b36 rotates synchronously, driving the incomplete gear 39 to rotate synchronously. Utilizing the meshing drive between the incomplete gear 39 and the toothed ring 40, the toothed plate 34 is driven to move up and down reciprocally under force. By using the meshing drive between the toothed plate 34 and the spur gear a33, the two crushing rolls 32 perform reciprocating forward and reverse rotations, and the limestone is crushed by the rotation of the two crushing rolls 32.

[0028] Example Two: Please refer to Figures 1-3 , this embodiment further elaborates on Example One, and the difference lies in a method of feeding limestone.

A sliding groove 23 is formed on the cover plate 11, and a fixed rod slidably connected to the inside of the sliding groove 23 is fixed on the storage bin 1. When the cover plate 11 is forced to move, the cover plate 11 is caused to translate along the direction in which the sliding groove 23 is opened; It should be noted that through the configuration of the feeding unit 3, limestone can be accurately lifted to the required specific height in an efficient and convenient manner, thereby realizing an automated feeding operation process. This not only significantly improves the working efficiency of the fluidized transportation of limestone but also, through the setting of the baffle 59, ensures that after the limestone feeding work is completed, the storage bin 1 can be promptly and tightly closed, effectively preventing the dust generated during the feeding process from spreading to the outside, and thus preventing environmental pollution around, achieving the dual goals of environmental protection and high-efficiency production; Principle of feeding limestone using the feeding unit 3: Driven by the electric push rod 19, the connecting block 20 is forced to move. Utilizing the transmission of the connecting rod 22, the cover plate 11 is forced to translate along the outside of the storage bin 1, and by putting limestone into the feeding hopper 15, driven by the two air cylinders, the feeding hopper 15 is forced to flip along the axis of the rotating rod a14, thus completing the feeding work of limestone.

[0030] Example Three: Please refer toFigure 13 and Figure 14 , this embodiment further illustrates other embodiments, and the difference lies in a feeding method for limestone.

[0031] Furthermore, a feeding component 44 is arranged in the processing box 8. The feeding component 44 is used to quickly guide the materials into the bin 1.

And the two belt pulleys 49 are connected by a belt 50; It should be noted that through the setting of the feeding component 44, the crushed limestone can be quickly shaken and fed into the bin 1, avoiding the limestone staying inside the processing box 8 and accelerating the feeding speed of the crushed limestone.
