Description

Technical Field

[0001] The invention relates to the technical field of energy-saving building material production equipment, in particular to a cement production device with low-grade limestone as an ingredient. Background Art

[0002] Cement production equipment is a combination of a series of mechanical equipment and process flows used to produce cement in the manufacturing industry. These equipment usually include key links such as raw material crushing, pre-homogenization, raw material preparation, clinker calcination, and cement grinding. Among them, the clinker calcination process is the core link in the entire cement production process and is directly related to the quality and performance of the cement produced. With the fierce market competition, cement companies can only gain a foothold in the market by tapping their potential to further save energy and reduce consumption, reduce manufacturing costs and increase corporate profits. Nearly 80% of the raw materials for cement manufacturing are limestone, and high-grade limestone is generally used. Low-grade limestone is cheap and accounts for a considerable proportion. Therefore, in order to significantly reduce the cost of cement production and make rational use of low-grade limestone, it is necessary to use low-grade limestone to burn qualified cement clinker, thereby significantly reducing the production cost of cement clinker.

[0003] The existing low-grade limestone has a low calcium oxide content and a high internal impurity content. When the cement raw material made from it is calcined in a rotary kiln, these impurities easily form low eutectic products at high temperatures, increasing the risk of crusting on the kiln wall. On the one hand, the formation of crusting will block the material flow channel in the kiln, resulting in the material being unable to flow smoothly, thereby reducing production efficiency. On the other hand, it will increase the internal resistance of the rotary kiln, thereby increasing the gas flow resistance during the calcination process. In order to maintain normal production temperature and efficiency, more energy is needed to overcome these resistances, thereby increasing the required energy consumption. It can be seen from the above that the frequent crusting caused by the use of low-grade limestone to produce cement requires staff to frequently stop the rotary kiln for cleaning, which greatly affects the cement production. Therefore, based on the above problems, a cement production device with low-grade limestone ingredients is proposed. Summary of the Invention

[0004] The object of the present invention is to provide a cement production device with low-grade limestone as an ingredient, so as to solve the problem that in the calcination process of existing cement production devices, when calcining raw materials made of low-grade limestone, crusting is easily generated in the kiln, and the crusting prevents the material from flowing smoothly, thereby reducing production efficiency and increasing the required energy consumption.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the present invention, the kiln tail, transmission seat, rotary drum, kiln head and cleaning module are provided, so that the kiln tail is used to convey cement raw meal containing low-grade limestone to the rotary drum, and at the same time, the smoke generated during calcination can be discharged. After the transmission seat is in operation, it can drive the rotary drum to rotate, and the rotation of the rotary drum causes the incoming raw meal to move toward the kiln head. The burner at the kiln head can calcine the raw meal moving in the rotary drum and convert it into clinker. At the same time, a crust will appear on the inner wall of the rotary drum, and the cleaning module can automatically clean the inner wall of the rotary drum during operation and rotation, so that the calcination process of the cement production device can automatically clean the crust in the running rotary kiln when calcining the raw meal made of low-grade limestone, thereby solving the problem that the calcination process of the existing cement production device is prone to crusting in the kiln when calcining the raw meal made of low-grade limestone, and the crusting will prevent the material from flowing smoothly, thereby reducing production efficiency and increasing energy consumption, and requiring staff to frequently stop the rotary kiln for cleaning, which greatly affects cement production.

[0017] 2. In the present invention, by arranging the structures such as the probe part, the rail seat, the material collection module and the reset mechanism, the rail seat can guide the displacement of the material collection module, and the reset mechanism can reset the material collection module after sampling. When the material collection module is needed to sample the calcined clinker, the handle is pulled up to fit the handle with the frame bar, so that the iron frame that moves left with the arm plate can squeeze the handle, so that the handle drives the material box and the feed rack to move to the left through the damping limit rod and the base bar, so that the feed rack enters the discharge shell. At this time, part of the clinker falling from the discharge shell will pass through the feed port and fall into the guide plate. The clinker is guided by the guide plate to pass through the one-way plate and enter the interior of the material box. When the iron frame moves right with the arm plate, the squeezing of the iron frame is lost, and the first spring of the reset mechanism will Reset and expand, push the handle, damping limit rod, base bar, material box, and feeding rack to the right to reset, and then push the handle down to reset so that the handle is no longer in contact with the rack bar, completing the sampling of the clinker. The above sampling operation avoids direct manual sampling and avoids possible harm to the staff caused by the high temperature of the clinker during sampling. It realizes that after the calcination process of the cement production device calcines the raw material made of low-grade limestone, the calcined clinker can be automatically sampled, so that the subsequent staff can control the quality of the clinker after testing, and solves the problem that the quality of the clinker will greatly affect the quality of the subsequent cement, and the clinker made from low-grade limestone is prone to unstable quality due to reasons such as component fluctuations, and needs to be sampled and tested;

[0018] 3. In the present invention, by providing the material collecting module and the heat dissipation part and other structures, when the iron frame moves left with the arm plate, the iron frame will push the arm rod to the left and be adsorbed by the magnetic block, and the left movement of the arm rod will drive the push-pull plate to the left, and the left movement of the push-pull plate will squeeze the folding airbag, so that the airflow in the folding airbag passes through the seat shell and the exhaust valve pipe into the air outlet groove, and the airflow passes through the air outlet groove to enter the material box through the air inlet and the ventilation net, and then is discharged from the air outlet plate. On the one hand, the passage of the airflow can drive the rotation of the stirring impeller, and the rotation of the stirring impeller drives the displacement of the clinker, so that the airflow can take away the heat of the clinker as much as possible after passing through. On the other hand, the airflow entering through the ventilation net can clean the air outlet plate to avoid blockage of the air outlet plate. When the arm plate moves to the right, the right movement of the iron frame can drive the arm and the push-pull plate to move to the right through the adsorption of the magnetic block and the iron frame. The rightward displacement of the push-pull plate can drive the folding airbag to unfold. When the folding airbag unfolds, it will inflate to the outside through the exhaust valve tube. When the push-pull plate moves to the rightmost side of the base shell, the adsorption between the iron frame and the magnetic block will be disengaged as the iron frame moves further to the right. The above operation completes a cooling operation of the sampled clinker. The above multiple cooling operations can quickly reduce the temperature of the sampled clinker, so that after the clinker sampling is completed, the heat dissipation mechanism of the calcination process of the cement manufacturing device can automatically, quickly and efficiently cool the sampled clinker, solving the problem that the temperature of the sampled clinker is too high and is not conducive to detection by the staff.

The rear interface of the seat shell 77 is connected to an exhaust valve pipe 78. The front interface of the seat shell 77 is connected to an exhaust valve pipe 79. The lower end of the exhaust valve pipe 79 passes through the rail seat 45 and is connected to the air outlet groove 46.

The lower rectangular opening of the box 61 is fixedly connected with a ventilation net 68, and the interior of the box 61 is rotatably connected with a stirring impeller 69 at the lower side of the feeding rack 66. Through this arrangement, after the clinker sampling is completed, the heat dissipation part 7 of the calcining process of the cement manufacturing device can automatically, quickly and efficiently cool the sampled clinker; the iron frame 529 will contact the magnetic block 75 and the arm rod 74 when it moves with the arm plate 521. Through this arrangement, the iron frame 529 will inevitably be adsorbed with the magnetic block 75 after it moves to the left, and the exhaust valve pipe 78 is composed of a tube body and a one-way valve that flows from back to front, and the exhaust valve tube 79 is composed of a folded tube and a one-way valve that flows from back to front. Through this arrangement, the exhaust and gas extraction of the folded airbag 76 can be divided, and the air outlet groove 46 is connected to a group of air inlet holes 67 and the rectangular opening of the ventilation net 68. The ventilation net 68 is arranged on the lower side of the left end face of the air outlet plate 62.

[0045] Workflow: The calcination process of the cement production device calcines low-grade limestone into raw meal as follows. Note 1: All electrical appliances in this equipment are externally powered and controlled by an external controller. Note 2: All mechanisms and components of the cleaning module 5 are made of high-melting-point steel (except for the motor 53 and the motor 551).First, the kiln tail 1 is used to transport cement raw materials containing low-grade limestone to the drum 3, and can also discharge the smoke generated during calcination. After the transmission seat 2 is running, it can drive the drum 3 to rotate. The rotation of the drum 3 causes the incoming raw materials to move toward the kiln head 4, and the burner 43 of the kiln head 4 can calcine the raw materials moving in the drum 3 to turn them into clinker. At the same time, a crust will appear on the inner wall of the drum 3, and the cleaning module 5 can automatically clean the inner wall of the drum 3 in operation. On the one hand, the operation of the motor 53 is controlled to drive the gear column 54 to rotate, and the gear column 54 is engaged with the tooth groove 525 of the arm plate 521 to enable the positive and negative rotation of the gear column 54 to bring The movable arm plate 521 is displaced left and right with the rail plate 511 as the guide. On the other hand, the motor 551 is controlled to drive the rotating shaft 552 to rotate. Through the engagement of a set of bevel gears 555, the rotation of the rotating shaft 552 can drive the rotating block 553 and the special-shaped wheel 554 to rotate at high speed. When the convex block of the special-shaped wheel 554 contacts the base plate 563, the base plate 563, the transmission block 561 and the scraper 564 of the scraping part 56 are pushed outward to the right and the second spring 562 is compressed. When there is no contact, the transmission block 561 is reset by the elastic force of the second spring 562, so that the base plate 563 and the scraper 564 can be reset to the left. Through this operation, the operation of the transmission part 55 can allow the scraping part 56 to perform a small and high-speed left and right movement. When the scraping part 56 moves to the left, the scraper 564 can vibrate at high speed to improve its scraping ability. When cleaning, the motor 53 and the gear column 54 drive the probe 52 to move to the left. When the probe 52 moves, the scraper 56 will be driven to move. When the scraping part 56 moves to the left, the scraper 564 is squeezed by the crust in the rotating drum 3 and rotates downward, and the third spring 567 is squeezed by the rotating arm 568 and the transmission rod 566. When the scraping part 56 moves to the left (the left part of the rotating drum 3), the scraping part 56 is pulled back to the right by the reverse influence of the motor 53 and the gear column 54. The elastic force of the third spring 567 is restored to push the transmission rod 566 to move, and the displacement of the transmission rod 566 will cause the rotating arm 568 to rotate and drive the scraper 564 upward. When the end of the probe 52 contacts an object (which may be the cylinder wall or the crust on the cylinder wall), the scraper 564, which is pulled back to the right and vibrates at high speed, can scrape and clean the crust on the inner wall of the rotating drum 3, and the cleaned crust will fall into the groove 522. The spiral blade 57, which rotates with the rotating shaft 552, can transport the crust to the outlet 523. When the probe 52 is completely reset to the right, the outlet 523 will be aligned with the waste outlet 516. At this time, the crust at the outlet 523 can be discharged through the waste outlet 516. The above operation completes a cleaning action of the rotary drum 3, so that the calcination process of the cement production device can automatically clean the crust of the running rotary kiln without stopping the kiln when calcining the raw meal made of low-grade limestone;When sampling is required, first the rail seat 45 can guide the displacement of the sampling module 6, and the reset mechanism 47 can reset the sampling module 6 after sampling is completed. When the sampling module 6 is required to sample the calcined clinker, the handle 65 is pulled up to make the handle 65 fit with the frame bar 472, so that the iron frame 529 that moves left with the arm plate 521 can squeeze the handle 65, so that the handle 65 drives the material box 61 and the feeding rack 66 to move to the left through the damping limit rod 64 and the base bar 63, so that the feeding rack 66 enters the discharge shell 41. At this time, part of the clinker falling from the discharge shell 41 will pass through the feed port 662 and fall into the guide plate 663. The clinker is guided by the guide plate 663 to pass through the one-way plate 665 and enter the material box 6 1, when the iron frame 529 moves to the right along with the arm plate 521, the squeezing of the iron frame 529 is lost, and the first spring 473 of the reset mechanism 47 will reset and expand, pushing the handle 65, the damping limit rod 64, the base bar 63, the material box 61, and the feeding rack 66 to reset to the right, and then the handle 65 is pushed down and reset so that the handle 65 is no longer in contact with the rack bar 472, completing the sampling of the clinker. The above sampling operation avoids direct manual sampling and avoids possible harm to the staff caused by the high temperature of the clinker during sampling. After the calcination process of the cement production device calcines the raw meal made of low-grade limestone, the calcined clinker can be automatically sampled, so that the staff can control the quality of the clinker after subsequent testing;The cooling operation of sampling is as follows. When the iron frame 529 moves left with the arm plate 521, the iron frame 529 will push the arm rod 74 to the left and adsorb it with the magnetic block 75. The left movement of the arm rod 74 will drive the push-pull plate 73 to move left. The left movement of the push-pull plate 73 will squeeze the folding air bag 76, so that the air flow in the folding air bag 76 passes through the seat shell 77 and the exhaust valve pipe 79 into the air outlet groove 46. The air flow is transmitted through the air outlet groove 46 to enter the material box 61 through the air inlet 67 and the ventilation net 68, and then discharged from the air outlet plate 62. On the one hand, the passage of the air flow can drive the stirring impeller 69 to rotate, and the rotation of the stirring impeller 69 drives the displacement of the clinker, so that the air flow can take away the heat of the clinker as much as possible after passing through. On the other hand, the air flow entering through the ventilation net 68 can clean the air outlet plate 62 to avoid blockage of the air outlet plate 62. When the iron frame 529 moves right with the arm plate 521, it passes through the magnetic block 7 5 and the iron frame 529, so that the rightward movement of the iron frame 529 can drive the arm 74 and the push-pull plate 73 to move to the right. The rightward movement of the push-pull plate 73 can drive the folding air bag 76 to expand. When the folding air bag 76 is expanded, it will exhaust air to the outside through the exhaust valve pipe 78. When the push-pull plate 73 moves to the rightmost side of the base shell 71, the adsorption between the iron frame 529 and the magnetic block 75 will be released as the iron frame 529 moves further to the right. Through the above operation, a cooling operation of the sampled clinker is completed. Through the above multiple cooling operations, the temperature of the sampled clinker can be quickly reduced. After the clinker sampling is completed, the heat dissipation mechanism of the calcining process of the cement manufacturing device can automatically, quickly and efficiently cool the sampled clinker. After cooling is completed, the staff can remove the sampling module 6 from the rail seat 45 and then remove the feeding rack 66. At this time, the sampled clinker in the material box 61 can be poured out for testing.
