It can harden in the air or better harden in water, and can firmly bind materials such as sand and stone together. Cement production uses limestone and clay as the main raw materials. Raw materials are crushed, batched, and ground into raw materials, which are then fed into cement kilns to be calcined into clinker, and then the clinker is ground with an appropriate amount of gypsum. For a long time, cement, as an important cementitious material, has been widely used in civil construction, water conservancy, national defense and other projects.

[0037] Example:

[0038] Reference Figure 1-Figure 10 , a cement production and processing technology, comprising the following steps:

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

[0040] Step 2: Cooling the cement clinker: The higher temperature of the cement clinker will be transferred to the condensation ring 6 through the material guide pipe 4, so that the water flow in the condensation ring 6 is evaporated, thereby reducing the temperature of the cement clinker, which helps to form more glass phases in the cement clinker, improves the activity of the clinker, and helps to maintain the microstructure of the clinker, reduce microcracks inside the clinker, and improve its compressive strength.

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

[0042] Step 4: Add gypsum powder to the clinker during the grinding process, and mix the two by rotating the mixing plate 72 to form a final product.

[0043] Reference Figure 1-Figure 10 A cement production and processing device includes a mounting frame 1, a calcining furnace 2 and a grinding tank 3. The calcining furnace 2 is rotatably connected to the top of the mounting frame 1 through a rotating seat 21, and the calcining furnace 2 is tilted for automatic unloading. The calcining furnace 2 and the grinding tank 3 are connected through a material guide pipe 4. The material guide pipe 4 and the calcining furnace 2 are rotatably connected, and the material guide pipe 4 and the grinding tank 3 are fixedly connected. The device also includes: a grinding assembly, which is arranged in the grinding tank 3 and is used to grind cement clinker; a cooling assembly, which is arranged on the material guide pipe 4 and is used to cool the cement clinker after high-temperature calcination.

[0044] Reference Figure 1 , Figure 7 Among them, two driving shafts 22 are rotatably connected between the rotating seats 21 on both sides, and the two driving shafts 22 are connected by a pulley set 221. Driving rollers 222 are fixedly connected on both sides of the outer wall of the driving shaft 22, and driving rings 23 are fixedly connected on both sides of the outer wall of the calcining furnace 2. The driving rings 23 and the driving rollers 222 rotate in contact with each other. A driving motor 24 is fixedly connected to the side wall of the rotating seat 21, and the output shaft of the driving motor 24 is fixedly connected to the end of the driving shaft 22. A feeding pipe 25 is rotatably connected to the upper end of the calcining furnace 2, and the feeding 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 rotating seats 21 on both sides, and the feed pipe 25 and the guide pipe 4 are rotatably connected to it, and both are fixed on the rotating seat 21 and the grinding tank 3 respectively, that is, only the calcining furnace 2 will rotate, while the feed pipe 25 and the guide pipe 4 are stationary.

[0046] By setting the above structure, the mixed cement raw material is 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 material to form 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 is used to drive the calcining furnace 2 to rotate, so that the cement raw material inside it is turned over so that it can be evenly contacted with the high temperature in the calcining furnace 2, thereby effectively improving the calcining effect.

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

[0049] Through the arrangement of the above-mentioned structure, the higher temperature of the cement clinker will be transferred to the condensation ring 6 through the guide pipe 4, so that the water flow in the condensation ring 6 is evaporated, thereby reducing the temperature of the cement clinker, effectively improving the cooling efficiency, and helping to form more glass phases in the cement clinker, thereby improving the activity of the clinker, and rapid cooling can effectively prevent the growth of mineral crystals in the cement clinker, thereby ensuring the strength and stability of the cement; as the air pressure in the condensation ring 6 increases, the pressure accumulation slider 611 in the pressure accumulation tube 61 will be pushed to slide, and finally when the pressure accumulation slider 611 passes over the input port of the injection tube 62, the high-pressure steam accumulated in the condensation ring 6 will rush into the drive bin 63 along the injection tube 62, thereby driving the drive The turbine 631 rotates, thereby driving the grinding shaft 5 to rotate. At this time, the cement clinker will also enter the grinding tank 3 along the material guide pipe 4, and the grinding shaft 5 will drive the multiple sets of grinding rollers 511 to rotate, so as to grind the cement clinker in the cavity formed by the grinding seat 531 and the inner wall of the grinding tank 3, thereby realizing the effective utilization of high-temperature waste heat, reducing energy consumption, and improving economic benefits; and the steam that drives the driving turbine 631 to rotate will be pushed by the driving turbine 631 to move, thereby being condensed by the inner wall of the driving bin 63 and re-cooled and liquefied, and further condensed along the condensation pipe 64, and finally refluxed into the condensation ring 6, thereby realizing the recycling of water flow and improving energy saving effects.

[0050] Reference Figure 2 , Figure 5 , Fig. 9 and Fig.10 , wherein the grinding assembly includes a grinding shaft 5, which is rotatably connected to the grinding jar 3, and a plurality of grinding rods 51 are fixed at equal intervals on the side wall of the grinding shaft 5, and a grinding roller 511 is rotatably connected to the bottom end of the grinding rod 51, and a spring telescopic rod 52 is fixedly connected to the bottom of the grinding jar 3, and four groups of spring telescopic rods 52 are arranged at equal intervals along the center of the grinding jar 3, and the ends of the four groups of spring telescopic rods 52 are commonly fixedly connected to a screening mesh plate 53, the screening mesh plate 53 slides in contact with the inner wall of the grinding jar 3, and the screening mesh plate 53 is located below the grinding roller 511, and a grinding seat 531 is fixedly connected to the screening mesh plate 53, and the grinding seat 531 is rotatably sleeved on the grinding shaft 5; the bottom end of the grinding shaft 5 passes through the bottom of the screening mesh plate 53 and is fixedly connected to a positioning plate 54, and lower protrusions 541 are fixedly connected to both sides of the positioning plate 54, and upper protrusions 532 are fixedly connected to both sides of the bottom of the screening mesh plate 53, and the lower protrusions 541 are in active contact with the upper protrusions 532.

[0051] By setting the above structure, during the rotation of the grinding shaft 5, the lower protrusion 541 will be in active contact with the upper protrusion 532, which will push the screening mesh plate 53 to be lifted upward as a whole. Then, after the lower protrusion 541 and the upper protrusion 532 are released from the extrusion contact, the screening mesh plate 53 will be reset downward under the action of gravity and the rebound of the spring telescopic rod 52. This reciprocating process will cause the screening mesh plate 53 to shake as a whole, so that the material above it that meets the particle size will fall to the bottom of the grinding tank 3, effectively avoiding the accumulation and blockage of materials, thereby ensuring the use effect of the screening mesh plate 53.

[0052] Reference Figure 1 , Figure 2 , Figure 6 and Figure 7 , wherein, piston boxes 55 are fixedly connected on both sides of the mounting frame 1, a piston plate 551 is slidably connected in 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 on the driving ring 23 near the side of the guide tube 4, and the magnetic plates 231 and the piston plate 551 repel each other, a blowing pipe 56 is fixedly connected and connected to the side wall of the piston box 55, the other end of the blowing pipe 56 passes through the grinding tank 3 and the screening mesh plate 53 and extends into the grinding seat 531, and the blowing pipe 56 and the screening mesh plate 53 are slidably connected, a pneumatic blade 57 is fixedly connected to the outer wall of the grinding shaft 5 located in the grinding seat 531, and the output end of the blowing pipe 56 is opposite to the bottom inclined surface of the pneumatic blade 57, an air supply pipe 561 is fixedly connected and connected to the top of the inner cavity of the piston box 55, and a one-way valve is arranged in both the blowing pipe 56 and the air supply pipe 561.

[0053] It should be noted that the one-way valve in the 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 air flow to be supplemented into the piston box 55 .

[0054] By setting the above structure, during the rotation of the calcining furnace 2, the piston plate 551 will slide into the piston box 55 by the repulsive effect between the magnetic plate 231 and the piston plate 551, thereby compressing the gas in the piston box 55 and opening the one-way valve in the blowing pipe 56, so that this part of the gas enters the grinding seat 531 along the blowing pipe 56 and drives the pneumatic blade 57 to rotate, thereby increasing the driving force to drive the grinding roller 511 to rotate, accelerating the rotation speed of the grinding roller 511, improving the grinding efficiency, and entering the grinding seat The airflow in 531 will enter the air guide groove 8 along the exhaust groove 82, thereby accelerating the airflow speed transported from the air outlet groove 811 to the grinding jar 3, and improving the grinding effect and condensation efficiency; and 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 suction in the piston box 55, so that the one-way valve in the air supply pipe 561 is opened, so that the external air flow is replenished, thereby ensuring that the blowing pipe 56 can provide continuous wind supply.

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

[0056] It should be noted that the electromagnetic metering valve and the electromagnetic valve are both existing mature technologies, and their specific principles and structures will not be described in detail.

[0057] Through the arrangement of the above structure, the electromagnetic metering valve in the powder dropping pipe 71 will open automatically, and a certain amount of gypsum powder will be intermittently added into the grinding tank 3, and finely ground by the grinding roller 511. Finally, the cement clinker and gypsum powder that meet the particle size will pass through the screening mesh 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, so as to fully mix the cement clinker and gypsum powder, effectively improving the quality of the final product.

Secondly, the air pressure in the grinding tank 3 will be increased, so that the airflow is discharged from the bottom to the top along the air outlet pipe 83, thereby accelerating the airflow exchange speed in the grinding tank 3, achieving the cooling of the cement clinker while also improving the cooling effect of the condenser 64; and when the spring telescopic rod 52 is extended upward, suction will be generated inside it, thereby opening the one-way valve in the air intake pipe 522, so that the external airflow is supplemented into the spring telescopic rod 52, ensuring the continuous blowing.

[0061] Reference Figure 1-Figure 10In the present invention, when in use, the mixed cement raw material is fed into the calcining furnace 2 through the feed pipe 25, and the high temperature in the calcining furnace 2 is utilized to cause chemical reactions between the compounds in the cement raw material to form main cement minerals (calcium silicate and calcium aluminate, etc.), and 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 is utilized to drive the calcining furnace 2 to rotate, so that the cement raw material inside it is turned over so as to be evenly contacted with the high temperature in the calcining furnace 2, thereby effectively improving the calcining effect. As the calcining furnace 2 rotates, the cement clinker will enter the guide pipe 4. At this time, the cement clinker contains a relatively high temperature, and this part of the temperature will be transmitted to the condensation ring 6 through the guide pipe 4, so that the water flow in the condensation ring 6 is evaporated. As the air pressure in the condensation ring 6 increases, the pressure accumulation slider 611 in the pressure accumulation tube 61 will be pushed to slide. Finally, when the pressure accumulation slider 611 passes over the input port of the injection pipe 62, the high-pressure steam accumulated in the condensation ring 6 will rush into the drive bin 63 along the injection pipe 62, thereby driving the driving turbine 631 to rotate, and then driving the grinding shaft 5 to rotate. At this time, the cement clinker will also enter the grinding tank 3 along the guide pipe 4, and the grinding shaft 5 will drive the multiple groups of grinding rollers 511 to rotate, so as to grind the cement clinker in the cavity formed by the grinding seat 531 and the inner wall of the grinding tank 3, so as to effectively utilize the high-temperature waste heat, reduce energy consumption, and improve economic benefits. At the same time, the electromagnetic metering valve in the powder drop pipe 71 will automatically open, and intermittently add a certain amount of gypsum powder into the grinding tank 3 to mix it with the cement clinker, and grind it finely through the grinding roller 511, effectively improving the production quality of cement. The steam that drives the driving turbine 631 to rotate will be pushed by the driving turbine 631 to be condensed by the inner wall of the driving bin 63 to cool down and liquefy again, and further condense along the condensing pipe 64, and finally flow back to the condensing ring 6, so as to realize the recycling of water flow and improve the energy saving effect.

[0062] During the rotation of the grinding shaft 5, the lower protrusion 541 will be in active contact with the upper protrusion 532, which will push the screening mesh plate 53 to be lifted upward as a whole. Then, when the lower protrusion 541 and the upper protrusion 532 are out of extrusion contact, the screening mesh plate 53 will be reset downward under the action of gravity and the rebound of the spring telescopic rod 52. This reciprocating process will cause the screening mesh plate 53 to shake as a whole, so that the material above it that meets the particle size will fall to the bottom of the grinding tank 3, effectively avoiding material accumulation and blockage, thereby ensuring the use effect of the screening mesh plate 53. When the spring telescopic rod 52 retracts downward, the gas in its inner cavity will be compressed and the one-way valve in the air guide pipe 521 will be opened, so that this part of the airflow will 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 blow into the grinding tank 3 along the air outlet ring 81 and the air outlet groove 811, thereby pushing the material to move quickly toward the grinding roller 511, thereby improving the grinding efficiency. Secondly, the air pressure in the grinding tank 3 will increase, so that the airflow will be discharged from the bottom to the top along the air outlet pipe 83, thereby accelerating the airflow exchange speed in the grinding tank 3, achieving the cooling of the cement clinker while also improving the cooling effect of the condenser 64.

[0063] And during the rotation of the calcining furnace 2, the repulsive effect between the magnetic plate 231 and the piston plate 551 will cause the piston plate 551 to slide into the piston box 55, thereby compressing the gas in the piston box 55 and opening the one-way valve in the blowing pipe 56, so that this part of the gas enters the grinding seat 531 along the blowing pipe 56 and drives the pneumatic blades 57 to rotate, thereby increasing the driving force for driving the grinding roller 511 to rotate, accelerating the rotation speed of the grinding roller 511, and improving the grinding efficiency. The airflow entering the grinding seat 531 will enter the air guide groove 8 along the exhaust groove 82, thereby accelerating the airflow speed of the air outlet groove 811 to the grinding tank 3, thereby further improving the grinding effect and condensation efficiency. Finally, cement clinker and gypsum powder that meet the particle size will pass through the screening mesh 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, so as to fully mix the cement clinker and gypsum powder, effectively improving the quality of the final product. After the production is completed, the solenoid valve in the discharge pipe 73 can be opened to discharge the material, thereby completing the entire cement processing procedure.
