Description

Technical Field

[0001] This utility model relates to the field of cement production technology, and in particular to a raw material feeding device for raw meal preparation. Background Technology

[0002] In the process of raw material preparation, the processing of raw materials is a crucial step. Traditional raw material handling devices are often single-function and cannot meet the requirements of modern production for the uniformity, dryness and efficient processing of raw materials.

[0003] In the raw material feeding stage, the lack of an effective mixing device makes the raw materials prone to clumping, resulting in uneven feeding and affecting the stability of subsequent processing and product quality. Moreover, during the feeding process, the absence of a reasonable screening and dispersing structure means that large pieces of raw materials or clumps may block the feeding channel, reducing production efficiency and increasing equipment failure rate. In addition, for the preparation of some raw materials that are sensitive to moisture content, traditional equipment lacks dedicated drying equipment, making it difficult to control the moisture content of the raw materials, which in turn affects the chemical reactivity of the raw materials and the performance of the final product.

[0004] Therefore, we propose a raw material feeding device for raw material preparation. Utility Model Content

[0005] The main purpose of this utility model is to provide a raw material feeding device for raw material preparation. In order to prevent problems such as uneven feeding due to raw material agglomeration, blockage of the feeding channel due to the lack of screening and dispersing structure, and difficulty in controlling the moisture content of raw materials due to the lack of drying equipment, this device can improve the uniformity, stability and efficiency of raw material processing during raw material preparation, ensure the smooth progress of subsequent processing and improve the quality and performance of the final product. It can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A raw material feeding device for raw material preparation includes a base plate. A support and a feeding box are respectively provided on the upper surface of the base plate. A feeding mechanism is provided on the top of the support. The feeding mechanism consists of a lifting component and a feeding hopper provided on one side of the lifting component. The feeding hopper is located above the feeding box. A stirring shaft is rotatably connected to both ends of the feeding hopper through bearings. Multiple annular array stirring rods are welded to the outer walls of the two stirring shafts. The stirring rods on the two stirring shafts are arranged crosswise. A pulley is fixedly connected to the same end of the two stirring shafts through the feeding hopper. The two pulleys are connected by a belt. A first motor is fixedly installed on the outer wall of the feeding hopper near the pulley. The output shaft of the first motor is fixedly connected to one of the pulleys.

[0008] The feeding box has two placement trays inside, and each of the two placement trays has a fixing rod at both ends. The end of the fixing rod away from the placement tray is fixedly connected to the inner side wall of the feeding box. The bottom surface of the placement tray has multiple through holes. A second motor is fixedly installed on the upper surface of the feeding box. The output end of the second motor is fixedly connected to a shaft. The shaft extends through the feeding box into the interior and is fixedly connected to a rotating rod. The bottom end of the rotating rod is fixedly connected to four levers, and the lower part of the levers is located inside the placement tray below.

[0009] Hot air blowers are symmetrically arranged on both ends of the outer wall of the feeding box. One end of the hot air blower is fixedly connected to an air supply pipe, and the end of the air supply pipe away from the hot air blower extends into the interior of the feeding box and is fixedly connected to an air supply hood.

[0010] By adopting the above technical solution, firstly, the height of the feeding hopper can be adjusted by the lifting component to adapt to different feeding needs. When raw materials need to be fed, the materials are placed into the feeding hopper. Then, the first motor starts, driving the connected pulley to rotate. Since the two pulleys are connected by a belt, the other pulley will also rotate synchronously, causing the two stirring shafts to rotate simultaneously. The stirring rods on the outer wall of the stirring shafts are arranged in a crisscross pattern. During the rotation, the raw materials in the feeding hopper are stirred. This stirring action can prevent the raw materials from clumping and make the raw materials more evenly distributed in the feeding hopper, ensuring that they can be smoothly fed into the feeding box later.

[0011] After being stirred, the raw materials are fed into the feeding box from the feeding hopper. There are two placement trays in the feeding box, which are fixed to the inner side wall of the feeding box by fixing rods. The raw materials will fall onto the upper placement tray first. There are multiple through holes on the bottom surface of the placement tray, which can allow the raw materials to be initially screened or dispersed to a certain extent. The second motor is started, which drives the shaft to rotate, thereby causing the rotating rod and the lever to rotate. The lower part of the lever is located in the lower placement tray. During the rotation, the lever can push the raw materials on the placement tray, allowing them to fall down through the through holes. If there are clumps of raw materials, the pushing of the lever can also help to break them up, allowing the raw materials to pass through the placement tray smoothly.

[0012] When the hot air blower is started, the generated hot air is delivered to the air supply hood through the air pipe. The air supply hood evenly distributes the hot air inside the feed box. The hot air flows inside the feed box, making full contact with the raw materials. The heat of the hot air evaporates the moisture in the raw materials, thereby achieving the purpose of drying the raw materials. This process can ensure the quality of raw materials and the smooth progress of subsequent processing, especially for some raw material preparation processes that have requirements on moisture content.

[0013] Furthermore, an inlet is provided at the edge of the feed box near the top of the support, and a discharge ramp is welded to the upper part of one side inner wall of the feed box, directly below the inlet.

[0014] By adopting the above technical solution, after the raw materials are stirred in the feeding hopper of the feeding mechanism, they are fed into the feeding box through the bottom opening of the feeding hopper. The raw materials first enter the feeding box through the inlet set at the edge of the feeding box. Since the feeding ramp is welded to the upper part of the inner wall of the feeding box at an inclination, the raw materials will slide down along the inclination angle of the ramp after falling on it. This can avoid the situation where the raw materials fall directly vertically and accumulate in a local area or cause a large impact on the placement tray. The raw materials slide down the feeding ramp onto the placement tray, and then can be further processed according to the working principle of the placement tray, lever and other components described above, such as screening and dispersing, so as to prepare for the subsequent raw material preparation process.

[0015] Furthermore, the lifting assembly includes a hydraulic cylinder and a side plate. Both the hydraulic cylinder and the side plate are fixedly installed on the upper end face of the bracket, and two sets of side plates are arranged opposite each other. The hydraulic cylinder is located between the two side plates, and a top plate is fixedly installed on the output end of the hydraulic cylinder.

[0016] By adopting the above technical solution, when it is necessary to adjust the height of the feeding hopper, the hydraulic cylinder starts to work. The hydraulic cylinder is powered by the hydraulic system to push the top plate at its output end to move up and down.

[0017] Furthermore, two symmetrical connecting rods are provided on one side of the top plate, and the other end of the connecting rods is fixedly connected to the upper part of one side of the feeding hopper, which is located directly above the inlet.

[0018] By adopting the above technical solution, when the hydraulic cylinder drives the top plate to move up and down, this motion is transmitted to the feeding hopper through the connecting rod. Since the connecting rod is fixedly connected to the upper part of one side of the feeding hopper, it can stably drive the feeding hopper to move up and down synchronously. This connection method can ensure the stability of the feeding hopper during height adjustment and prevent the feeding hopper from shaking or tilting. At the same time, the feeding hopper is located directly above the inlet. This position design ensures that when feeding, the raw material can accurately fall into the inlet through the bottom opening of the feeding hopper and then into the feeding box. When feeding is required, after the raw material is evenly mixed, it enters the feeding box from the bottom of the feeding hopper through the inlet by gravity. In this process, the connection structure formed by the connecting rod and the top plate ensures the accuracy and reliability of the feeding process.

[0019] Furthermore, limit rods are fixedly installed inside both side plates, and limit blocks are provided on both sides of the top plate, with both limit blocks slidably sleeved on the upper part of the outer side of the limit rods.

[0020] By adopting the above technical solution, when the hydraulic cylinder drives the top plate to move up and down, the limiting blocks on both sides of the top plate will move together with the top plate. Since the limiting blocks are slidably sleeved on the upper part of the outer side of the limiting rod, the limiting rod provides guidance for the movement of the limiting blocks and the top plate. The limiting rod is fixedly installed inside the side plate and its direction is vertical. This ensures that the top plate can only move up and down in the vertical direction. This limiting structure can prevent the top plate from shifting horizontally during the movement. When the thrust of the hydraulic cylinder may not be completely uniform or is affected by external interference, the cooperation of the limiting blocks and the limiting rod can correct the movement direction of the top plate, ensure the position accuracy of the feeding hopper during the height adjustment process, and make the feeding hopper accurately positioned directly above the inlet, thereby ensuring that the raw materials are smoothly fed from the feeding hopper into the feeding box.

[0021] Furthermore, a conveyor belt is provided on the bottom inner wall of the feed box, and a discharge port is provided on the lower part of the feed box on the side away from the support. One end of the conveyor belt extends to the outside through the discharge port.

[0022] By adopting the above technical solution, after the raw materials have completed the previous pre-treatment process in the feeding box, such as screening on the placement tray, being dispersed by the lever, and being dried by the hot air blower, the raw materials will fall onto the conveyor belt on the inner wall of the bottom of the feeding box. Due to the friction, the raw materials will move towards the discharge port along with the conveyor belt. One end of the conveyor belt extends to the outside through the discharge port, which allows the raw materials to be smoothly carried out of the feeding box by the conveyor belt. After the raw materials are sent out from the discharge port, they can directly enter the next raw material preparation process. This setting realizes the continuous and orderly flow of raw materials in the entire raw material preparation system and ensures the continuity of the production process.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] (1) This utility model provides a raw material feeding device for raw material preparation, which is equipped with a stirring shaft and cross stirring rods. Driven by a first motor, it can fully stir the raw materials, effectively prevent the raw materials from clumping, and make the raw materials evenly distributed in the feeding hopper, ensuring the uniformity and stability of the raw material feeding. At the same time, the placement plate in the feeding box cooperates with the lever structure. By rotating the lever, the raw materials on the placement plate are moved and dispersed. This not only helps the raw materials to be initially screened or dispersed through the through holes on the placement plate, but also further processes the clumped raw materials, ensuring the uniform flow of the raw materials in the feeding box, providing a good raw material foundation for the subsequent raw material preparation process, and helping to improve the quality consistency of the raw material products.

[0025] (2) The present invention provides a raw material feeding device for raw material preparation. The device is equipped with a hot air blower, an air supply pipe and an air supply hood, which can evenly distribute hot air inside the feeding box. After the raw material enters the feeding box, the hot air comes into full contact with the raw material. The principle of heat transfer is used to make the moisture in the raw material evaporate quickly, thus realizing the drying treatment of the raw material. This process plays a key role in controlling the moisture content of the raw material, which can meet the strict requirements of specific raw material preparation processes on the moisture content of the raw material, improve the chemical reactivity of the raw material, thereby ensuring the smooth progress of the raw material preparation process and the stable performance of the final product, reducing product defects and production accidents caused by raw material moisture problems, and improving the reliability and production efficiency of the entire raw material preparation production line.

[0031] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0032] To prevent uneven feeding due to raw material agglomeration, blockage of the feed channel due to the lack of a screening and dispersing structure, and difficulty in controlling the moisture content of raw materials due to the lack of drying equipment, this study aims to improve the uniformity, stability, and efficiency of raw material processing during raw material preparation, ensuring smooth subsequent processing and improving the quality and performance of the final product. Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a raw material feeding device for raw material preparation includes a base plate 1. A support 2 and a feeding box 4 are respectively provided on the upper surface of the base plate 1. A feeding mechanism 3 is provided on the top of the support 2. The feeding mechanism 3 consists of a lifting component 5 and a feeding hopper 6 provided on one side of the lifting component 5. The feeding hopper 6 is located above the feeding box 4. The two ends of the feeding hopper 6 are rotatably connected to a stirring shaft 7 through bearings. Multiple ring-shaped stirring rods 8 are welded to the outer walls of the two stirring shafts 7. The stirring rods 8 on the two stirring shafts 7 are arranged crosswise. The same end of the two stirring shafts 7 passes through the feeding hopper 6 and is fixedly connected to a pulley 9. The two pulleys 9 are connected by a belt. A first motor 10 is fixedly installed on the outer wall of the feeding hopper 6 near the pulley 9. The output shaft of the first motor 10 is fixedly connected to one of the pulleys 9.

[0033] The feeding box 4 is provided with two placement trays 12. Each of the two placement trays 12 is provided with a fixing rod 11 at both ends. The end of the fixing rod 11 away from the placement tray 12 is fixedly connected to the inner side wall of the feeding box 4. The bottom surface of the placement tray 12 is provided with multiple through holes 17. A second motor 13 is fixedly installed on the upper surface of the feeding box 4. The output end of the second motor 13 is fixedly connected to a shaft 14. The shaft 14 extends through the feeding box 4 into the interior and is fixedly connected to a rotating rod 15. The bottom end of the rotating rod 15 is fixedly connected to four levers 16. The lower part of the levers 16 is located inside the placement tray 12 below.

[0034] Hot air blowers 18 are symmetrically arranged on both ends of the outer wall of the feeding box 4. One end of the hot air blower 18 is fixedly connected to an air supply pipe 19. The end of the air supply pipe 19 away from the hot air blower 18 extends into the interior of the feeding box 4 and is fixedly connected to an air supply hood 20.

[0035] In use, firstly, the height of the feeding hopper 6 can be adjusted by the lifting component 5 to adapt to different feeding needs. When raw materials need to be fed, the raw materials are placed into the feeding hopper 6. Then, the first motor 10 starts, driving the connected pulley 9 to rotate. Since the two pulleys 9 are connected by a belt, the other pulley 9 will also rotate synchronously, thereby causing the two stirring shafts 7 to rotate simultaneously. The stirring rods 8 on the outer wall of the stirring shafts 7 are arranged in a crisscross pattern. During the rotation, the raw materials in the feeding hopper 6 are stirred. This stirring action can prevent the raw materials from clumping and make the raw materials more evenly distributed in the feeding hopper 6, ensuring that they can be smoothly fed into the feeding box 4 later.

[0036] After being stirred, the raw materials are fed into the feeding box 4 from the feeding hopper 6. There are two placement trays 12 inside the feeding box 4, which are fixed to the inner side wall of the feeding box 4 by the fixing rod 11. The raw materials will fall onto the upper placement tray 12 first. The bottom surface of the placement tray 12 has multiple through holes 17, which can allow the raw materials to be initially screened or dispersed to a certain extent. The second motor 13 is started, which drives the shaft 14 to rotate, thereby causing the rotating rod 15 and the lever 16 to rotate. The lower part of the lever 16 is located in the lower placement tray 12. During the rotation, the lever 16 can push the raw materials on the placement tray 12, so that they can fall down through the through holes 17. If there are clumps of raw materials, the pushing of the lever 16 can also help to break them up, allowing the raw materials to pass smoothly through the placement tray 12.

[0037] The hot air blower 18 starts, and the generated hot air is delivered to the air supply hood 20 through the air supply pipe 19. The air supply hood 20 evenly distributes the hot air inside the feed box 4. The hot air flows inside the feed box 4, making full contact with the raw materials. The heat of the hot air evaporates the moisture in the raw materials, thereby achieving the purpose of drying the raw materials. This process can ensure the quality of the raw materials and the smooth progress of subsequent processing, especially for some raw material preparation processes that have requirements on moisture content.

[0038] For example, such as Figure 1 , Figure 3 As shown, the present invention also includes an inlet 27 provided at the edge of the feed box 4 near the top of the support 2, and a discharge sloping plate 28 welded to the upper part of one side inner wall of the feed box 4 and directly below the inlet 27.

[0039] In use, after the raw materials are stirred in the feeding hopper 6 of the feeding mechanism 3, they are fed into the feeding box 4 through the bottom opening of the feeding hopper 6. The raw materials first enter the feeding box 4 through the inlet 27 set on the edge of the feeding box 4. Since the feeding inclined plate 28 is welded to the upper part of the inner wall of the feeding box 4 at an inclination, the raw materials will slide down along the inclination angle of the inclined plate after falling on the feeding inclined plate 28. This can avoid the situation that the raw materials may accumulate in a local area or cause a large impact on the placement tray 12 if they fall directly vertically. The raw materials slide down the feeding inclined plate 28 onto the placement tray 12, and then can be further processed according to the working principle of the placement tray 12, lever 16 and other components described above, such as screening and dispersing, so as to prepare for the subsequent raw material preparation process.

[0040] For example, such as Figure 2 As shown, the present invention also includes the lifting assembly 5, which includes a hydraulic cylinder 21 and a side plate 23. The hydraulic cylinder 21 and the side plate 23 are both fixedly installed on the upper end face of the bracket 2, and two sets of side plates 23 are arranged opposite each other. The hydraulic cylinder 21 is located between the two side plates 23, and a top plate 22 is fixedly installed on the output end of the hydraulic cylinder 21.

[0041] When it is necessary to adjust the height of the feeding hopper 6 during use, the hydraulic cylinder 21 starts to work. The hydraulic cylinder 21 is powered by the hydraulic system to push the top plate 22 at its output end to move up and down.

[0042] For example, such as Figure 2 As shown, the present invention also includes two symmetrical connecting rods 26 on one side of the top plate 22, and the other end of the connecting rods 26 is fixedly connected to the upper part of one side of the feeding hopper 6, and the feeding hopper 6 is located directly above the feeding port 27.

[0043] In use, when the hydraulic cylinder 21 drives the top plate 22 to move up and down, this motion is transmitted to the feeding hopper 6 through the connecting rod 26. Since the connecting rod 26 is fixedly connected to the upper part of one side of the feeding hopper 6, it can stably drive the feeding hopper 6 to move up and down synchronously. This connection method can ensure the stability of the feeding hopper 6 during height adjustment and prevent the feeding hopper 6 from shaking or tilting. At the same time, the feeding hopper 6 is located directly above the inlet 27. This position design ensures that when feeding, the raw material can accurately fall into the inlet 27 through the bottom opening of the feeding hopper 6 and then into the feeding box 4. When feeding is required, after the raw material is evenly mixed, it enters the feeding box 4 from the bottom of the feeding hopper 6 through the inlet 27 by gravity. In this process, the connection structure formed by the connecting rod 26 and the top plate 22 ensures the accuracy and reliability of the feeding process.

[0044] For example, such as Figure 2As shown, the present invention also includes a limiting rod 24 fixedly installed inside the two side plates 23, and a limiting block 25 provided on both sides of the top plate 22, and the two limiting blocks 25 are slidably sleeved on the upper part of the outer side of the limiting rod 24.

[0045] In use, when the hydraulic cylinder 21 drives the top plate 22 to move up and down, the limiting blocks 25 on both sides of the top plate 22 will move together with the top plate 22. Since the limiting blocks 25 are slidably sleeved on the upper outer side of the limiting rod 24, the limiting rod 24 provides guidance for the movement of the limiting blocks 25 and the top plate 22. The limiting rod 24 is fixedly installed inside the side plate 23 and its direction is vertical. This ensures that the top plate 22 can only move up and down in the vertical direction. This limiting structure can prevent the top plate 22 from shifting horizontally during the movement. If the thrust of the hydraulic cylinder 21 is not completely uniform or is affected by external interference, the cooperation of the limiting blocks 25 and the limiting rod 24 can correct the movement direction of the top plate 22, ensuring the position accuracy of the feeding hopper 6 during the height adjustment process, so that the feeding hopper 6 can be accurately positioned directly above the inlet 27, thereby ensuring that the raw materials are smoothly fed from the feeding hopper 6 into the feeding box 4.

[0046] For example, such as Figure 1 , Figure 3 As shown, the present invention also includes a conveyor belt 30 provided on the inner wall of the bottom end of the feeding box 4, and a discharge port 29 provided on the lower part of the side of the feeding box 4 away from the support 2, with one end of the conveyor belt 30 extending to the outside through the discharge port 29.

[0047] In use, after the raw materials have completed the pre-treatment process in the feed box 4, such as being screened on the placement tray 12, being dispersed by the lever 16, and being dried by the hot air blower 18, the raw materials will fall onto the conveyor belt 30 on the inner wall of the bottom of the feed box 4. Due to the friction, the raw materials will move towards the discharge port 29 along with the conveyor belt 30. One end of the conveyor belt 30 extends to the outside through the discharge port 29, which allows the raw materials to be smoothly carried out of the feed box 4 by the conveyor belt 30. After the raw materials are sent out from the discharge port 29, they can directly enter the next raw material preparation process. This setting realizes the continuous and orderly flow of raw materials in the entire raw material preparation system, ensuring the continuity of the production process.

[0048] It should be noted that this utility model is a raw material feeding device for raw material preparation. According to the height of the feeding source and the actual feeding requirements, the hydraulic cylinder 21 is activated. The hydraulic cylinder 21 pushes the top plate 22 up and down through the hydraulic system. The limiting blocks 25 on both sides of the top plate 22 slide along the limiting rod 24 in the side plate 23 to ensure that the top plate 22 moves vertically, thereby driving the feeding hopper 6 connected to it through the connecting rod 26 to adjust to a suitable height, and ensuring that the feeding hopper 6 is located directly above the feeding port 27.

[0049] The raw materials are placed into the feeding hopper 6 with the height adjusted, and the first motor 10 is started. The first motor 10 drives the connected pulley 9 to rotate, and the two stirring shafts 7 rotate synchronously through belt transmission. The stirring rods 8 arranged crosswise on the stirring shafts 7 stir the raw materials to prevent clumping and make the raw materials evenly distributed.

[0050] After mixing, the raw materials fall through the bottom opening of the feeding hopper 6 and the inlet 27 of the feeding box 4 onto the discharge inclined plate 28. They slide down the inclined plate to the upper placement plate 12. The second motor 13 is started, which drives the shaft 14, the rotating rod 15 and the lever 16 to rotate. The lever 16 moves the raw materials on the placement plate 12, causing them to fall through the through hole 17. The clumps of raw materials can also be broken up. At the same time, the hot air blower 18 is started. Hot air enters the inside of the feeding box 4 through the air pipe 19 and the air supply hood 20, and comes into full contact with the raw materials to evaporate the moisture in the raw materials and dry them.

[0051] After processing, the raw materials fall onto the conveyor belt 30 on the inner wall of the bottom of the feed box 4. The conveyor belt 30 transports the raw materials toward the discharge port 29, allowing the raw materials to pass through the discharge port 29 and extend to the outside, entering the next raw material preparation process.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
