Description

Technical Field

[0001] This utility model relates to the field of concrete processing technology, and more specifically, to a centrifugal mixing device for concrete processing. Background Technology

[0002] Concrete is one of the most important civil engineering materials in modern times. It has the characteristics of abundant raw materials, low price, simple production process, high compressive strength, good durability and wide strength grade range. In the production process of concrete, mixing is a key step, which directly affects the quality and performance of concrete. However, in existing facilities, concrete raw materials contain a large amount of crushed stone. If these stones are not processed before mixing, it will affect the quality of the concrete, resulting in waste of raw materials and manpower.

[0003] A search revealed that Chinese patent CN219855253U discloses a mixing device for concrete processing. In this structure, a motor drives a rotating rod and a mixing rod to rotate, thereby mixing and processing the raw materials. A filter plate 1 performs initial filtration of the raw materials, with residual materials sliding into a crushing box. A lever rotates with the rotating rod and adjusts according to the inclined surface of the filter plate 1. Its bottom contacts the top of the filter plate 1 to remove crushed stones. The lever repeatedly engages with the filter holes, causing the filter plate 1 to vibrate and prevent clogging. A driven shaft 1 rotates with the rotating rod and drives a driven shaft 2 via a belt drive, causing the rotating shaft to drive the crushing blade to crush the crushed stones. The filter plate 2 filters the qualified raw materials, and the material guide box pours the crushed and filtered raw materials into the box for further mixing. The filter screen performs secondary filtration of the mixed raw materials. The rotating scraper squeezes the fixing block, causing the mounting plate to be compressed and reset by the rubber block, thus polarizing the filter screen, preventing clogging, and ensuring smooth subsequent material discharge.

[0004] However, in actual use, after the material is filtered by the filter plate, the material remaining above the filter plate slides down into the crushing box through the material drop plate and is then crushed by the rotating crushing blade. The transmission path is relatively long, resulting in a lot of time and material loss during the transmission process. Furthermore, the material cannot be dispersed before crushing, which affects the uniformity of concrete mixing. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a centrifugal mixing concrete processing and mixing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A centrifugal concrete processing mixing device includes a mixing drum, a frame fixedly installed on the outside of the mixing drum, multiple material pipes passing through the top of the mixing drum, and a centrifugal mechanism installed inside the mixing drum. The centrifugal mechanism includes a motor fixedly installed on the top of the mixing tank, a rotating shaft fixedly installed at the output end of the motor, a centrifugal cylinder fixedly installed on the surface of the rotating shaft, multiple through holes opened on the surface of the centrifugal cylinder, multiple crushing blades fixedly installed on the surface of the rotating shaft, the crushing blades being located inside the centrifugal cylinder, and one end of the material tube extending into the interior of the centrifugal cylinder. One end of the motor passes through the mixing tank and is rotatably connected to the inner wall of the mixing tank. A support frame is fixedly installed on the outside of the rotating shaft, and the support frame is located at the bottom of the centrifuge cylinder.

[0007] By adopting the above technical solution, multiple material pipes facilitate proportional feeding and direct entry into the centrifuge cylinder. Furthermore, the through holes in the centrifuge mechanism enable preliminary centrifugal mixing, and the crushing blade can crush large particles, thereby improving the mixing quality.

[0008] As a further description of the above technical solution: a mixing mechanism is provided on one side of the support frame. The mixing mechanism includes multiple springs fixedly arranged on both sides of the support frame. A U-shaped scraper is fixedly arranged at one end of each spring. Multiple movable cylinders are provided on both sides of the support frame. A movable rod is slidably arranged inside the movable cylinder. One end of the movable rod is connected to the surface of the U-shaped scraper. The spring sleeve is arranged outside the movable cylinder and the movable rod. Both ends of the U-shaped scraper are fixedly provided with T-shaped guide blocks, and the inside of the support frame is provided with guide grooves, and the T-shaped guide blocks are slidably connected to the guide grooves; A connecting rod is fixedly installed on the inner wall of the U-shaped scraper, and a fixed cylinder is sleeved on the outside of the connecting rod. Multiple auxiliary arc-shaped plates are fixedly installed on the surface of the fixed cylinder, and multiple first stirring rods are fixedly installed on the surface of the connecting rod.

[0009] By adopting the above technical solution, the scraper can slide along the inner wall of the mixing drum under the action of centrifugal force and material movement, which can effectively scrape off the material adhering to the drum wall, avoid material accumulation affecting the mixing effect, ensure the stability of the U-shaped scraper when sliding, make its work more reliable, and also stir the surrounding materials, increase the mixing range and intensity, and further enhance the uniformity and fullness of concrete mixing.

[0010] As a further description of the above technical solution: a connecting column is fixedly provided on one side of the support frame, and a stirring rod and a second stirring rod are fixedly provided on one end of the connecting column, with the second stirring rod provided on one side of the stirring rod; Multiple inclined scrapers are fixedly installed on the surface of the rotating shaft, and a stabilizing plate is fixedly installed between each of the multiple inclined scrapers. Multiple stirring rods are fixedly installed inside the stabilizing plate, and multiple stirring blades are sleeved on the outside of the stirring rods. A discharge pipe is provided through the bottom of the mixing tank, and a butterfly valve is provided on one side of both the material pipe and the discharge pipe.

[0011] By adopting the above technical solution: as the support frame rotates and penetrates deeper into the material, it can promote longitudinal mixing of the material, enhance the comprehensiveness of mixing, improve the mixing quality, and also perform transverse stirring of the material. The combination of longitudinal and transverse mixing makes the material more uniform and thorough. Furthermore, the discharge pipe enables the smooth discharge of the mixed concrete, ensuring the integrity and efficiency of the mixing device's workflow.

[0012] The technical effects and advantages of this utility model are as follows: 1. By setting up a centrifugal mechanism, compared with existing technologies, one end of the material pipe extends into the centrifuge cylinder, ensuring that raw materials directly enter the key mixing area, reducing material transfer time and loss, improving feeding efficiency, and generating centrifugal force through the high-speed rotation of the centrifuge cylinder, which allows the material to diffuse in all directions through the surface holes, achieving preliminary mixing, increasing the contact area and mixing opportunities between materials. At the same time, the crushing blades on the rotating shaft can crush larger particles entering the centrifuge cylinder, refining the particles and avoiding uneven mixing due to excessively large particles, thus improving the uniformity and quality of concrete mixing. From feeding to preliminary mixing and crushing, the process is continuous, which can quickly and effectively complete the concrete processing and mixing work, improve production efficiency, and provide reliable equipment support for concrete production. 2. By setting up a mixing mechanism, compared with existing technologies, the anti-sticking effect is better. The U-shaped scraper slides under the action of springs, which can effectively scrape off the material adhering to the inner wall of the mixing barrel, avoid material accumulation affecting the mixing uniformity, ensure the barrel wall is clean, and extend the service life of the equipment. Moreover, the first stirring rod and auxiliary rod on the U-shaped scraper, the stirring rod and second stirring rod on the connecting column, as well as the stirring components on the inclined scraper and the stabilizing plate, stir the material from different angles and directions, promote the longitudinal and transverse mixing of the material, and greatly improve the mixing effect. Secondly, the structure has good stability. The T-shaped guide block and the guide groove cooperate to ensure the smooth sliding of the U-shaped scraper, and the stabilizing plate enhances the structural stability of the inclined scraper, making the equipment operation more reliable.

[0021] The embodiments disclosed in this application are as follows: Figure 1-6 The centrifugal mixing concrete processing mixing device shown includes a mixing drum 1, a frame 2 fixedly installed on the outside of the mixing drum 1, multiple material pipes 3 passing through the top of the mixing drum 1, and a centrifugal mechanism installed inside the mixing drum 1.

A centrifugal cylinder 6 is fixedly installed on the surface of the rotating shaft 5. Multiple through holes 7 are opened on the surface of the centrifugal cylinder 6. Multiple crushing blades 8 are fixedly installed on the surface of the rotating shaft 5. The crushing blades 8 are located inside the centrifugal cylinder 6. One end of the material pipe 3 extends into the interior of the centrifugal cylinder 6. One end of the motor 4 passes through the mixing tank 1 and is rotatably connected to the inner wall of the mixing tank 1. A support frame 9 is fixedly installed on the outside of the rotating shaft 5, and the support frame 9 is located at the bottom of the centrifuge cylinder 6. Open the butterfly valve 28 on one side of the material pipe 3 to transport concrete raw materials such as cement, sand, gravel, water and admixtures into the mixing tank 1 through multiple material pipes 3 in a certain proportion and order. Since one end of the material pipe 3 extends into the centrifuge 6, the raw materials will directly enter the centrifuge 6. Then start motor 4. The output end of motor 4 drives the rotating shaft 5 to rotate. The rotating shaft 5 drives the centrifuge cylinder 6 to rotate at high speed. The multiple through holes 7 on the surface of the centrifuge cylinder 6 cause the material to spread to the surroundings under the action of centrifugal force, and the initial mixing begins. Meanwhile, multiple crushing blades 8 fixedly mounted on the surface of the rotating shaft 5 rotate inside the centrifuge cylinder 6 with the rotating shaft 5, crushing larger particles of material entering the centrifuge cylinder 6 to make the particles smaller, which facilitates uniform mixing in the subsequent process.

[0022] Reference Figure 2-4 As shown, a mixing mechanism is provided on one side of the support frame 9. The mixing mechanism includes multiple springs 10 fixedly installed on both sides of the support frame 9. A U-shaped scraper 11 is fixedly installed at one end of each spring 10. Multiple movable cylinders 12 are provided on both sides of the support frame 9. A movable rod 13 is slidably installed inside the movable cylinder 12. One end of the movable rod 13 is connected to the surface of the U-shaped scraper 11. The springs 10 are sleeved on the outside of the movable cylinder 12 and the movable rod 13. Both ends of the U-shaped scraper 11 are fixedly provided with T-shaped guide blocks 14, and the inside of the support frame 9 is provided with guide grooves 15, and the T-shaped guide blocks 14 are slidably connected to the guide grooves 15. A connecting rod 16 is fixedly installed on the inner wall of the U-shaped scraper 11, and a fixed cylinder 17 is sleeved on the outside of the connecting rod 16. Multiple auxiliary arc plates 18 are fixedly installed on the surface of the fixed cylinder 17, and multiple first stirring rods 19 are fixedly installed on the surface of the connecting rod 16. As the rotating shaft 5 rotates, the support frame 9 fixed outside the rotating shaft 5 also rotates. The mixing mechanism on both sides of the support frame 9 starts to work. Due to the centrifugal force and the movement of the material, the U-shaped scraper 11 slides to a certain extent on the inner wall of the mixing barrel 1 under the elastic action of the spring 10. The T-shaped guide blocks 14 at both ends of the U-shaped scraper 11 slide in the guide groove 15 inside the support frame 9 to ensure the stability of the sliding of the U-shaped scraper 11. The U-shaped scraper 11 can scrape off the material adhering to the inner wall of the mixing barrel 1 to prevent the material from accumulating and affecting the mixing effect. The connecting rod 16 fixed to the inner wall of the U-shaped scraper 11 moves together with the U-shaped scraper 11. The fixed cylinder 17 sleeved on the outside of the connecting rod 16 and the multiple auxiliary arc plates 18 on the surface of the fixed cylinder 17 will stir the surrounding materials. At the same time, the multiple first stirring rods 19 fixed on the surface of the connecting rod 16 can also play an auxiliary stirring role, further enhancing the mixing effect.

[0023] Reference Figure 5-6 As shown, a connecting column 20 is fixedly installed on one side of the support frame 9, and a stirring rod 21 and a second stirring rod 22 are fixedly installed on one end of the connecting column 20. The second stirring rod 22 is located on one side of the stirring rod 21. Multiple inclined scrapers 23 are fixedly installed on the surface of the rotating shaft 5. A stabilizing plate 24 is fixedly installed between the multiple inclined scrapers 23. Multiple stirring rods 25 are fixedly installed inside the stabilizing plate 24. Multiple stirring blades 26 are sleeved on the outside of the stirring rods 25. A discharge pipe 27 is provided through the bottom of the mixing tank 1. A butterfly valve 28 is provided on one side of the material pipe 3 and the discharge pipe 27. The connecting column 20 fixed on one side of the support frame 9 has a stirring rod 21 and a second stirring rod 22 at one end. As the support frame 9 rotates, the stirring rod 21 and the second stirring rod 22 are designed to stir the material. The shape and position of the stirring rod 21 and the second stirring rod 22 are designed to penetrate deep into the material and promote the longitudinal mixing of the material. Multiple inclined scrapers 23 fixedly mounted on the surface of the rotating shaft 5 rotate with the rotating shaft 5. The inclined scrapers 23 push the material at the bottom. The stabilizing plate 24 fixedly mounted between the multiple inclined scrapers 23 ensures the structural stability of the inclined scrapers 23. Multiple stirring rods 25 fixed inside the stabilizing plate 24 and multiple stirring blades 26 sleeved outside the stirring rods 25 perform transverse stirring of the passing material, making the material more uniformly mixed. Once the concrete mixture reaches the required uniformity, turn off motor 4 to stop mixing, and then open butterfly valve 28 on one side of discharge pipe 27. Under the action of gravity, the mixed concrete is discharged from discharge pipe 27 at the bottom of mixing bucket 1.

[0024] Working principle of this utility model: This utility model is a centrifugal mixing concrete processing mixing device. When using the device, firstly, open the butterfly valve 28 on one side of the material pipe 3, and transport concrete raw materials such as cement, sand, gravel, water and admixtures into the mixing tank 1 through multiple material pipes 3 in a certain proportion and order. Since one end of the material pipe 3 extends into the interior of the centrifuge 6, the raw materials will directly enter the centrifuge 6. Then start motor 4. The output end of motor 4 drives the rotating shaft 5 to rotate. The rotating shaft 5 drives the centrifuge cylinder 6 to rotate at high speed. The multiple through holes 7 on the surface of the centrifuge cylinder 6 cause the material to spread to the surroundings under the action of centrifugal force, and the initial mixing begins. Meanwhile, multiple crushing blades 8 fixedly installed on the surface of the rotating shaft 5 rotate with the rotating shaft 5 inside the centrifuge cylinder 6, crushing larger particles of material entering the centrifuge cylinder 6, making the particles smaller and facilitating uniform mixing in the subsequent process. As the rotating shaft 5 rotates, the support frame 9 fixed outside the rotating shaft 5 also rotates. The mixing mechanism on both sides of the support frame 9 starts to work. Due to the centrifugal force and the movement of the material, the U-shaped scraper 11 slides to a certain extent on the inner wall of the mixing barrel 1 under the elastic action of the spring 10. The T-shaped guide blocks 14 at both ends of the U-shaped scraper 11 slide in the guide groove 15 inside the support frame 9 to ensure the stability of the sliding of the U-shaped scraper 11. The U-shaped scraper 11 can scrape off the material adhering to the inner wall of the mixing barrel 1 to prevent the material from accumulating and affecting the mixing effect. The connecting rod 16 fixed to the inner wall of the U-shaped scraper 11 moves together with the U-shaped scraper 11. The fixed cylinder 17 sleeved on the outside of the connecting rod 16 and the multiple auxiliary arc plates 18 on the surface of the fixed cylinder 17 will stir the surrounding materials. At the same time, the multiple first stirring rods 19 fixed on the surface of the connecting rod 16 can also play an auxiliary stirring role, further enhancing the mixing effect. The connecting column 20 fixed on one side of the support frame 9 has a stirring rod 21 and a second stirring rod 22 at one end. As the support frame 9 rotates, the stirring rod 21 and the second stirring rod 22 are designed to stir the material. The shape and position of the stirring rod 21 and the second stirring rod 22 are designed to penetrate deep into the material and promote the longitudinal mixing of the material. Multiple inclined scrapers 23 fixedly mounted on the surface of the rotating shaft 5 rotate with the rotating shaft 5. The inclined scrapers 23 push the material at the bottom. The stabilizing plate 24 fixedly mounted between the multiple inclined scrapers 23 ensures the structural stability of the inclined scrapers 23. Multiple stirring rods 25 fixed inside the stabilizing plate 24 and multiple stirring blades 26 sleeved outside the stirring rods 25 perform transverse stirring of the passing material, making the material more uniformly mixed. Once the concrete mixture reaches the required uniformity, turn off motor 4 to stop mixing, then open butterfly valve 28 on one side of discharge pipe 27. Under the action of gravity, the mixed concrete is discharged from discharge pipe 27 at the bottom of mixing bucket 1, completing the entire concrete mixing process.
