Description

Technical Field

[0001] This invention relates to the field of cement production and processing, and in particular to a cement production and processing apparatus. Background Technology

[0002] Cement is an inorganic gel material that, when mixed with water, forms a paste that hardens in air or, even better, in water, and can firmly bind materials such as sand and stone together. Cement production uses limestone and clay as the main raw materials, which are crushed, batched, and ground to produce raw meal. This raw meal is then fed into a cement kiln and calcined into clinker. The clinker is then ground with an appropriate amount of gypsum to produce cement. For a long time, cement has been widely used as an important cementing material in civil engineering, water conservancy, national defense, and other projects.

[0003] Currently, after cement raw meal is calcined into clinker, the clinker needs to be rapidly cooled to improve its activity and reduce the growth of internal mineral crystals, which helps to improve the strength and stability of cement. However, most existing methods dissipate heat by blowing it into the air with fan blades, which is generally inefficient and wastes waste heat resources. Furthermore, additional power is required for grinding, which is not energy-saving and increases production energy consumption. Therefore, a cement production and processing device is proposed. Summary of the Invention

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0037] Example:

[0038] Reference Figures 1-10 A cement production and processing technology includes the following steps:

[0039] Step 1: Calcine the mixed raw materials at high temperature to form cement clinker: The mixed cement raw materials are fed into the calcining furnace 2 through the feed pipe 25. The high temperature in the calcining furnace 2 causes chemical reactions between the compounds in the cement raw materials to form the main cement minerals and gradually transform into cement clinker.

[0040] Step 2: Cooling and reducing the temperature of cement clinker: The high temperature of cement clinker will be transferred to the condensing ring 6 through the feed pipe 4, causing the water in the condensing ring 6 to evaporate, thereby reducing the temperature of cement clinker. This helps to form more glass phase in cement clinker, improves clinker activity, helps to maintain the microstructure of clinker, reduces microcracks inside clinker, and improves its compressive strength.

[0041] Step 3: Grinding the cooled cement clinker: The grinding shaft 5 will drive multiple sets of grinding rollers 511 to rotate, thereby grinding the cement clinker located in the cavity formed by the grinding seat 531 and the inner wall of the grinding tank 3.

[0042] Step 4: During the grinding process, gypsum powder is added to the clinker, and the two are mixed by the rotation of the mixing plate 72 to form the final product.

[0043] Reference Figures 1-10 A cement production and processing apparatus includes a mounting frame 1, a calcining furnace 2, and a grinding jar 3. The calcining furnace 2 is rotatably connected to the top of the mounting frame 1 via a rotating base 21, and the calcining furnace 2 is inclined to facilitate automatic material feeding. The calcining furnace 2 and the grinding jar 3 are connected by a guide pipe 4, which is rotatably connected to the calcining furnace 2 and fixedly connected to the grinding jar 3. The apparatus also includes: a grinding assembly disposed inside the grinding jar 3 for grinding cement clinker; and a cooling assembly disposed on the guide pipe 4 for cooling the cement clinker after high-temperature calcination.

[0044] Reference Figure 1 , Figure 7 Two drive shafts 22 are rotatably connected between the two rotating seats 21. The two drive shafts 22 are connected by a belt pulley group 221. Drive rollers 222 are fixedly connected to both sides of the outer wall of the drive shafts 22. Drive rings 23 are fixedly connected to both sides of the outer wall of the calcining furnace 2. The drive rings 23 and drive rollers 222 rotate in contact. A drive motor 24 is fixedly connected to the side wall of the rotating seat 21. The output shaft of the drive motor 24 is fixedly connected to the end of the drive shaft 22. A feed pipe 25 is rotatably connected to the upper end of the calcining furnace 2. The feed pipe 25 is fixedly connected to the side wall of the rotating seat 21.

[0045] It should be noted that the calcining furnace 2 rotates between the two rotating seats 21, and the feed pipe 25 and the guide pipe 4 are rotatably connected to it. They are fixed to the rotating seat 21 and the grinding tank 3 respectively. In other words, only the calcining furnace 2 will rotate, while the feed pipe 25 and the guide pipe 4 are stationary.

[0046] With the above-mentioned structure, the mixed cement raw meal is fed into the calcining furnace 2 through the feed pipe 25. The high temperature inside the calcining furnace 2 causes chemical reactions between the compounds in the cement raw meal to form the main cement minerals (calcium silicate and calcium aluminate, etc.), which are gradually transformed into cement clinker. At the same time, the drive motor 24 is turned on, and the friction between the drive ring 23 and the drive roller 222 drives the calcining furnace 2 to rotate, causing the cement raw meal inside to turn over so that it can come into uniform contact with the high temperature inside the calcining furnace 2, effectively improving the calcination effect.

[0047] Reference Figures 1-3 and Figure 5 The cooling assembly includes a condensing ring 6, which is sleeved and fixed on the outer wall of the feed pipe 4. The top of the condensing ring 6 is fixed and connected to a pressure accumulator pipe 61. The side wall of the pressure accumulator pipe 61 is fixed and connected to a jet pipe 62. A pressure accumulator slider 611 is slidably connected inside the pressure accumulator pipe 61. A second spring 612 is fixedly connected between the top of the pressure accumulator slider 611 and the inner wall of the pressure accumulator pipe 61. The top of the grinding tank 3 is fixedly connected to a drive chamber 63. The grinding shaft 5 passes through the drive chamber 63 and is fixedly connected to a drive turbine 631. The end of the jet pipe 62 away from the pressure accumulator pipe 61 is connected to the inner cavity of the drive chamber 63, and the output end of the jet pipe 62 faces the side wall of the drive turbine 631. The bottom of the drive chamber 63 is fixed and connected to a condensing pipe 64. The condensing pipe 64 passes through the grinding tank 3 and is connected to the upper part of the inner cavity of the condensing ring 6. A one-way valve is installed inside the condensing pipe 64.

[0048] It should be noted that the one-way valve inside the condenser 64 can only allow the condensed liquid to enter the condenser ring 6.

[0049] With the above-described structure, the high temperature of the cement clinker is transferred to the condensing ring 6 through the feed pipe 4, causing the water in the condensing ring 6 to evaporate, thereby reducing the temperature of the cement clinker and effectively improving cooling efficiency. This helps to form more glassy phase in the cement clinker, increasing its activity. Furthermore, rapid cooling effectively prevents the growth of mineral crystals in the cement clinker, ensuring cement strength and stability. As the air pressure inside the condensing ring 6 increases, it will push the pressure accumulator slider 611 in the pressure accumulator pipe 61 to slide. Finally, when the pressure accumulator slider 611 passes the input port of the jet pipe 62, the high-pressure steam accumulated in the condensing ring 6 will rush into the drive chamber 63 along the jet pipe 62, thereby driving the drive... The turbine 631 rotates, which in turn drives the grinding shaft 5 to rotate. At this time, the cement clinker will enter the grinding tank 3 along the feed pipe 4. The grinding shaft 5 will drive multiple sets of grinding rollers 511 to rotate, thereby grinding the cement clinker in the cavity formed by the grinding seat 531 and the inner wall of the grinding tank 3. This achieves effective utilization of high-temperature waste heat, reduces energy consumption, and improves economic efficiency. The steam that drives the turbine 631 to rotate will be pushed by the turbine 631 to receive the condensation effect of the inner wall of the drive chamber 63 and be cooled and liquefied again. It will then undergo further condensation along the condenser pipe 64 and finally flow back into the condenser ring 6, realizing the recycling of water flow and improving energy saving.

[0050] Reference Figure 2 , Figure 5 , Figure 9 and Figure 10 The grinding assembly includes a grinding shaft 5, which is rotatably connected inside the grinding jar 3. Multiple grinding rods 51 are fixed at equal intervals on the side wall of the grinding shaft 5. Grinding rollers 511 are rotatably connected to the bottom ends of the grinding rods 51. Spring telescopic rods 52 are fixedly connected to the bottom of the grinding jar 3. Four sets of spring telescopic rods 52 are evenly spaced along the center of the grinding jar 3, and the ends of the four sets of spring telescopic rods 52 are all fixedly connected to a screening screen plate 53. The screening screen plate 53 slides against the inner wall of the grinding jar 3 and is located below the grinding rollers 511. A grinding seat 531 is fixedly connected to the screening screen plate 53 and rotatably sleeved on the grinding shaft 5. The bottom end of the grinding shaft 5 extends through to below the screening screen plate 53 and is fixedly connected to a positioning disc 54. Lower protrusions 541 are fixedly connected to both sides of the positioning disc 54, and upper protrusions 532 are fixedly connected to both sides of the bottom of the screening screen plate 53. The lower protrusions 541 and upper protrusions 532 are in contact with each other.

[0051] With the above-described structure, during the rotation of the grinding shaft 5, the lower protrusion 541 and the upper protrusion 532 will come into contact, thereby pushing the screening screen plate 53 upward. Then, after the lower protrusion 541 and the upper protrusion 532 are no longer in contact, the screening screen plate 53 will return to its original position under the action of gravity and the spring extension rod 52. This process repeats, causing the screening screen plate 53 to vibrate, allowing materials of the correct particle size to fall to the bottom of the grinding tank 3, effectively preventing material accumulation and blockage, and ensuring the effectiveness of the screening screen plate 53.

[0052] Reference Figure 1 , Figure 2 , Figure 6 and Figure 7 Piston boxes 55 are fixedly connected to both sides of the mounting frame 1. A piston plate 551 is slidably connected inside the piston box 55. A first spring 552 is fixedly connected between the side wall of the piston plate 551 and the inner wall of the piston box 55. A magnetic plate 231 is fixedly connected to the drive ring 23 near the guide pipe 4. The magnetic plate 231 and the piston plate 551 are magnetically repelled. A blower pipe 56 is fixed and connected to the side wall of the piston box 55. The other end of the blower pipe 56 passes through the grinding tank 3 and the screening screen plate 53 and extends into the grinding seat 531. The blower pipe 56 and the screening screen plate 53 are slidably connected. A wind turbine blade 57 is fixedly connected to the outer wall of the grinding shaft 5 located in the grinding seat 531. The output end of the blower pipe 56 faces the bottom inclined surface of the wind turbine blade 57. An air supply pipe 561 is fixed and connected to the top of the inner cavity of the piston box 55. A one-way valve is provided in both the blower pipe 56 and the air supply pipe 561.

[0053] It should be noted that the one-way valve in the air blowing pipe 56 can only allow the gas in the piston box 55 to enter the grinding seat 531; the one-way valve in the air supply pipe 561 can only allow the external airflow to supplement the piston box 55.

[0054] With the above-described structure, during the rotation of the calcining furnace 2, the repulsive force between the magnetic plate 231 and the piston plate 551 causes the piston plate 551 to slide into the piston box 55, thereby compressing the gas inside the piston box 55. This, in turn, opens the one-way valve in the air blowing pipe 56, allowing this gas to enter the grinding seat 531 along the air blowing pipe 56 and drive the pneumatic blades 57 to rotate. This increases the driving force for rotating the grinding roller 511, accelerates the rotation speed of the grinding roller 511, improves grinding efficiency, and allows the gas to enter the grinding seat. The airflow in 531 will enter the air guide groove 8 along the exhaust groove 82, thereby accelerating the airflow speed delivered from the exhaust groove 811 to the grinding tank 3, improving the grinding effect and condensation efficiency; when the magnetic plate 231 and the piston plate 551 are separated from the repulsive area, the piston plate 551 will be reset under the rebound action of the first spring 552, thereby generating a suction effect in the piston box 55, causing the one-way valve in the air supply pipe 561 to open, allowing the external airflow to be supplemented, thereby ensuring that the blower pipe 56 can provide a continuous air supply.

[0055] Reference Figure 2 , Figure 5 and Figure 9 The grinding tank 3 is fixedly connected to the top of a gypsum powder box 7. The bottom sides of the gypsum powder box 7 are connected to the inner cavity of the grinding tank 3 through powder discharge pipes 71. An electromagnetic metering valve is installed in the powder discharge pipes 71. The bottom sides of the positioning plate 54 are fixedly connected to a mixing plate 72. The bottom end of the grinding tank 3 is fixed and connected to a discharge pipe 73. An electromagnetic valve is installed in the discharge pipe 73.

[0056] It should be noted that both electromagnetic metering valves and electromagnetic valves are existing mature technologies, and their specific principles and structures will not be elaborated here.

[0057] With the above-mentioned structure, the electromagnetic metering valve in the powder discharge pipe 71 will automatically open, intermittently feeding a certain amount of gypsum powder into the grinding tank 3, and then finely grinding it through the grinding roller 511. Finally, cement clinker and gypsum powder of the correct particle size will pass through the screening screen plate 53 and fall to the bottom of the grinding tank 3. At this time, the positioning plate 54 will drive the mixing plate 72 to rotate, thereby fully mixing the cement clinker and gypsum powder, effectively improving the quality of the final product. After production is completed, the electromagnetic valve in the discharge pipe 73 can be opened to discharge the material, thus completing the entire cement processing procedure.

[0058] Reference Figure 2 , Figure 4 , Figure 6 and Figure 10In this configuration, a guide ring 542 is slidably sleeved on the outer wall of the positioning disc 54. A guide pipe 521 is fixed and connected to the bottom sleeve side wall of the spring telescopic rod 52. The other end of the guide pipe 521 is fixed to the side wall of the guide ring 542 and communicates with its inner cavity. An air intake pipe 522 is fixed and connected to the bottom sleeve side wall of the spring telescopic rod 52. Both the guide pipe 521 and the air intake pipe 522 are equipped with one-way valves. An air guide groove 8 is opened in the inner cavity of the grinding shaft 5. An air inlet groove 543 is opened in the guide ring 542. The air inlet groove 543 communicates with the inner cavity of the guide ring 542. The guide groove 8 extends to the positioning disc 54. The grinding shaft 5 has an internal air inlet groove 543 and an air outlet ring 81 fixedly connected to its outer wall. The air outlet ring 81 has an air outlet groove 811 on its side wall and is connected to the top of the inner cavity of the air guide groove 8. The grinding shaft 5 located in the grinding seat 531 has an exhaust groove 82 on its outer wall and is connected to the inner cavity of the air guide groove 8. The top of the grinding tank 3 is fixed and connected to an exhaust pipe 83. A dust filter 831 is installed in the input end of the exhaust pipe 83. The dust filter 831 is used to prevent cement powder in the grinding tank 3 from overflowing during the ventilation process, thus avoiding material loss and dust pollution.

[0059] It should be noted that the one-way valve in the air guide pipe 521 can only allow the airflow in the spring telescopic rod 52 to enter the air guide groove 8; the one-way valve in the air intake pipe 522 can only allow the external airflow to enter the spring telescopic rod 52.

[0060] With the above-described structure, when the spring telescopic rod 52 retracts downwards, it compresses the gas inside its cavity and opens the one-way valve in the air guide pipe 521. This allows the airflow to enter the air guide groove 8 along the air guide pipe 521, the air guide ring 542, and the air inlet groove 543, and finally blown into the grinding jar 3 along the air outlet ring 81 and the air outlet groove 811. This pushes the material to move quickly towards the grinding roller 511, improving the grinding efficiency. Secondly, it increases the air pressure inside the grinding jar 3, causing the airflow to be discharged from the bottom upwards along the air outlet pipe 83. This accelerates the airflow exchange speed inside the grinding jar 3, achieving cooling of the cement clinker while also improving the cooling effect of the condenser pipe 64. When the spring telescopic rod 52 extends upwards, it generates suction inside, thereby opening the one-way valve in the suction pipe 522, allowing external airflow to supplement the spring telescopic rod 52, ensuring continuous blowing.

[0061] Reference Figures 1-10In this invention, during use, the mixed cement raw meal is fed into the calcining furnace 2 through the feed pipe 25. The high temperature inside the calcining furnace 2 causes chemical reactions between the compounds in the cement raw meal, forming the main cement minerals (calcium silicate and calcium aluminate, etc.), which gradually transform into cement clinker. At the same time, the drive motor 24 is turned on, and the friction between the drive ring 23 and the drive roller 222 drives the calcining furnace 2 to rotate, causing the cement raw meal inside to turn over, so that it can come into uniform contact with the high temperature inside the calcining furnace 2, effectively improving the calcination effect. As the calcining furnace 2 rotates, cement clinker enters the feed pipe 4. At this time, the cement clinker has a high temperature, which is transferred to the condensing ring 6 through the feed pipe 4, causing the water in the condensing ring 6 to evaporate. As the air pressure in the condensing ring 6 increases, it will push the pressure accumulator slider 611 in the pressure accumulator pipe 61 to slide. Finally, when the pressure accumulator slider 611 passes the input port of the jet pipe 62, the high-pressure steam accumulated in the condensing ring 6 will rush into the drive chamber 63 along the jet pipe 62, thereby driving the drive turbine 631 to rotate, which in turn drives the grinding shaft 5 to rotate. At this time, the cement clinker will enter the grinding tank 3 along the feed pipe 4. The grinding shaft 5 will drive multiple sets of grinding rollers 511 to rotate, thereby grinding the cement clinker in the cavity formed by the grinding seat 531 and the inner wall of the grinding tank 3. This achieves effective utilization of high-temperature waste heat, reduces energy consumption, and improves economic efficiency. At the same time, the electromagnetic metering valve in the powder drop pipe 71 will automatically open, intermittently adding a certain amount of gypsum powder into the grinding tank 3, mixing it with the cement clinker, and then finely grinding it through the grinding rollers 511, effectively improving the production quality of cement. The steam that drives the turbine 631 to rotate will be pushed by the turbine 631 to receive the condensation effect of the inner wall of the drive chamber 63, cool down and liquefy again, and undergo further condensation along the condenser pipe 64, finally flowing back into the condenser ring 6, realizing the recycling of water flow and improving energy saving.

[0062] During the rotation of the grinding shaft 5, the lower protrusion 541 and the upper protrusion 532 will come into contact, which will push the screening screen plate 53 upward. Then, after the lower protrusion 541 and the upper protrusion 532 are no longer in contact, the screening screen plate 53 will return to its original position under the action of gravity and the spring extension rod 52. This process will cause the screening screen plate 53 to shake, so that the material above that meets the particle size requirements falls to the bottom of the grinding tank 3, effectively avoiding material accumulation and blockage, and ensuring the performance of the screening screen plate 53. Furthermore, when the spring telescopic rod 52 retracts downward, it will compress the gas inside its cavity and open the one-way valve in the air guide pipe 521. This airflow will then enter the air guide groove 8 along the air guide pipe 521, the air guide ring 542, and the air inlet groove 543, and finally be blown into the grinding jar 3 along the air outlet ring 81 and the air outlet groove 811. This will push the material to move quickly towards the grinding roller 511, thereby improving the grinding efficiency. Secondly, it will increase the air pressure in the grinding jar 3, causing the airflow to be discharged from the bottom upward along the air outlet pipe 83. This will accelerate the airflow exchange speed in the grinding jar 3, thereby cooling the cement clinker and improving the cooling effect of the condenser pipe 64.

[0063] Furthermore, during the rotation of the calcining furnace 2, the repulsive force between the magnetic plate 231 and the piston plate 551 causes the piston plate 551 to slide into the piston box 55, thereby compressing the gas inside the piston box 55. This opens the one-way valve in the blower pipe 56, allowing this gas to enter the grinding seat 531 along the blower pipe 56 and drive the fan blades 57 to rotate. This increases the driving force for rotating the grinding roller 511, accelerates the rotation speed of the grinding roller 511, and improves the grinding efficiency. The airflow entering the grinding seat 531 will also enter the air guide groove 8 along the exhaust groove 82, thereby accelerating the airflow speed delivered from the exhaust groove 811 to the grinding tank 3, further improving the grinding effect and condensation efficiency. Finally, cement clinker and gypsum powder that meet the particle size requirements will pass through the screening screen 53 and fall to the bottom of the grinding tank 3. At this time, the positioning plate 54 will drive the mixing plate 72 to rotate, thereby fully mixing the cement clinker and gypsum powder, effectively improving the quality of the final product. After production is completed, the solenoid valve in the discharge pipe 73 can be opened to discharge the material, thus completing the entire cement processing procedure.
