Description

Technical Field

[0001] The utility model relates to the technical field of concrete processing, and particularly relates to a device for preventing precipitation of concrete admixtures. Background Technique

[0002] Concrete admixtures refer to substances added to improve and regulate the performance of concrete. The application of concrete admixtures in engineering has been increasingly valued. The addition of admixtures plays a certain role in improving the performance of concrete, but the selection, addition method and adaptability of admixtures will seriously affect its development. Most of the existing raw materials of concrete admixtures are in liquid form, which are mainly formed by adding various organic components and inorganic components into a reaction kettle according to a specified ratio and heating and mixing them. When storing them, the problem of precipitation needs to be considered.

[0003] A Chinese patent with the authorization announcement number CN220257804U for a device for preventing precipitation of concrete admixtures includes a stirring tank. A driving component is arranged at the top of the stirring tank, and a central spiral blade is arranged inside the stirring tank to drive the positive stirring of the concrete admixture by the driving component.

[0004] In the above patent, a spiral blade is used for stirring to prevent precipitation. During the stirring process, concrete adheres to the surface of the strip-shaped stirring blade, and the remaining concrete will adhere to the blade. When cleaning, it is impossible to effectively contact all surfaces, resulting in difficult removal of residues, forming a hard-to-clean solidified layer, affecting the quality of subsequent stirring, and even causing cross-contamination of the components of different batches of concrete. Therefore, this application provides a device for preventing precipitation of concrete admixtures to meet the requirements. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a device for preventing precipitation of concrete admixtures to solve the problems raised in the above background technique.

[0006] To solve the above technical problems, the utility model provides the following technical solutions:

[0007] A device for preventing precipitation of concrete admixtures includes a stirring barrel. A rotating pipe is rotatably connected inside the stirring barrel. A motor one is fixedly installed at the bottom of the stirring barrel, and the output end of the motor one is fixedly connected to the bottom of the rotating pipe. A top cover is installed at the top of the stirring barrel, and a motor two is fixedly installed at the top of the top cover. The output end of the motor two is fixedly installed with a rotating shaft, and a plurality of first bevel gears are fixedly installed on the outer wall of the rotating shaft. The outer wall of the first bevel gear is engaged with a second bevel gear, and a stirring plate is fixedly installed on one side of the second bevel gear.

[0008] Preferably, an activity groove is opened inside the stirring plate, a plurality of metal beads are arranged inside the activity groove, and a magnet is slidably connected to the outer wall of the stirring barrel.

[0009] Preferably, a handle is fixedly installed on one side of the magnet.

[0011] Preferably, a plurality of fixed disks are fixedly installed on the inner wall of the rotating tube, and a plurality of limiting disks are fixedly installed on the outer wall of the rotating shaft. The fixed disks are arranged below the limiting disks, and the rotating shaft movably penetrates through the inside of the fixed disks.

[0012] Preferably, the width of the bottom of the stirring plate is smaller than that of the top.

[0013] Preferably, a sealing ring is fixedly installed on the rotating tube, and the sealing ring is arranged on one side of the second bevel gear.

[0014] Preferably, the side of the stirring plate close to the stirring barrel is arc-shaped, and the arc-shaped protruding part of the stirring plate is in contact with the inner wall of the stirring barrel.

[0015] Compared with the prior art, the present utility model has at least the following beneficial effects:

[0016] In the above solution, by providing a plurality of stirring plates that can rotate and adjust the angle, the mixture inside the stirring barrel can be fully stirred during the working process. After the stirring is completed, the concrete mixture adheres to the outer wall of the stirring plate. Since the stirring plate can be adjusted to maintain a vertically downward state, the concrete can quickly drip downward from the outer wall of the stirring plate, avoiding the concrete from adhering to the surface of the stirring plate for a long time. When cleaning, the surface of the stirring plate is flat and easy to clean, avoiding the formation of a cured layer, ensuring the quality of subsequent stirring, and avoiding cross-contamination of the components of different batches of concrete.

[0017] By providing the movable groove and the metal beads, when the mixture inside the stirring barrel is discharged after the stirring is completed, the stirring plate continues to rotate, and the mixture on its surface continuously slides down due to the vibration of the stirring plate, thereby realizing the cleaning of the surface of the stirring plate and avoiding the formation of a cured layer due to the adhesion of concrete to the surface of the stirring plate.

[0030] As Figures 1-3 As shown, an embodiment of the present utility model provides a device for preventing precipitation of concrete admixtures, including a mixing barrel 1. A rotating tube 2 is rotatably connected inside the mixing barrel 1. A motor one 3 is fixedly installed at the bottom of the mixing barrel 1, and the output end of the motor one 3 is fixedly connected to the bottom of the rotating tube 2. A top cover 4 is installed at the top of the mixing barrel 1, and a motor two 5 is fixedly installed at the top of the top cover 4. The output end of the motor two 5 is fixedly installed with a rotating shaft 6. A plurality of first bevel gears 7 are fixedly installed on the outer wall of the rotating shaft 6. The outer wall of the first bevel gear 7 is engaged with a second bevel gear 8, and a stirring plate 9 is fixedly installed on one side of the second bevel gear 8.

[0031] When using this device, after pouring the admixture from the feed port at the top of the top cover 4 and when it is necessary to stir the concrete mixture inside the mixing barrel 1, start the motor one 3 to drive the rotating tube 2 to rotate. The rotating tube 2 drives the second bevel gear 8 and the stirring plate 9 to rotate. Since the rotating shaft 6 does not rotate when the motor two 5 is not started, the outer wall of the second bevel gear 8 meshes with the outer wall of the first bevel gear 7. The second bevel gear 8 rotates while revolving around the rotating shaft 6, so that while the stirring plate 9 revolves around the rotating shaft 6, it rotates around the central axis of the second bevel gear 8, thereby stirring the mixture inside the mixing barrel 1. Start the motor two 5 to drive the rotating shaft 6 and a plurality of first bevel gears 7 to rotate. The first bevel gear 7 drives the engaged second bevel gear 8 to rotate, and the second bevel gear 8 drives the stirring plate 9 to rotate. After the stirring is completed and the mixture in the mixing barrel 1 is discharged, start the motor two 5 to drive the rotating shaft 6 to rotate. The first bevel gear 7 drives the second bevel gear 8 and the stirring plate 9 to rotate until the narrower side of the stirring plate 9 faces downward. By providing a plurality of stirring plates 9 that can rotate and adjust the angle, the mixture inside the mixing barrel 1 can be fully stirred during the working process. After the stirring is completed, the concrete mixture adheres to the outer wall of the stirring plate 9. Since the stirring plate 9 can be adjusted to maintain a vertically downward state, the concrete can quickly drip downward from the outer wall of the stirring plate 9, preventing the concrete from adhering to the surface of the stirring plate 9 for a long time. The surface of the stirring plate 9 is flat and easy to clean during cleaning, avoiding the formation of a cured layer, ensuring the quality of subsequent stirring, and avoiding cross-contamination of the components of different batches of concrete.

[0032] As Figures 1-3As shown, an activity groove 10 is formed inside the stirring plate 9, a plurality of metal beads 11 are arranged inside the activity groove 10, and an electromagnet 12 is slidably connected to the outer wall of the stirring barrel 1.

[0033] When the stirring plate 9 rotates inside the stirring barrel 1, during the rotation of the stirring plate 9, the metal beads 11 move inside the activity groove 10, and the metal beads 11 collide with the inner wall of the activity groove 10, causing the stirring plate 9 to vibrate. When the stirring plate 9 rotates to one side of the electromagnet 12, the electromagnet 12 attracts the metal beads 11. When the stirring plate 9 moves away from the electromagnet 12, the metal beads 11 freely fall. By arranging the activity groove 10 and the metal beads 11, after the stirring is completed and the mixture inside the stirring barrel 1 is discharged, the stirring plate 9 continues to rotate, and the mixture on its surface continuously shakes off due to the vibration of the stirring plate 9, thereby realizing the cleaning of the surface of the stirring plate 9 and preventing concrete from adhering to the surface of the stirring plate 9 to form a solidified layer.

[0034] As Figure 1 and Figure 2 shown, a handle 13 is fixedly installed on one side of the electromagnet 12. When it is necessary to remove and replace the electromagnet 12, hold the handle 13 and pull out the electromagnet 12 upward.

[0035] As Figure 4 shown, the width of one side of the electromagnet 12 close to the rotating pipe 2 is greater than that of the other side. When the electromagnet 12 is installed on the outer wall of the stirring barrel 1, due to the greater width of the side of the electromagnet 12 close to the rotating pipe 2, the electromagnet 12 installed on one side of the stirring barrel 1 is not easily detached.

[0036] As Figure 5 shown, a plurality of fixed disks 14 are fixedly installed on the inner wall of the rotating pipe 2, and a plurality of limit disks 15 are fixedly installed on the outer wall of the rotating shaft 6. The fixed disks 14 are arranged below the limit disks 15, and the rotating shaft 6 movably penetrates through the inside of the fixed disks 14. By arranging the fixed disks 14 and the limit disks 15, since the rotating shaft 6 rotates relative to the rotating pipe 2, the fixed disks 14 support the limit disks 15 and the rotating shaft 6.

[0037] As Figure 3 shown, the width of the bottom of the stirring plate 9 is smaller than that of the top. Since the bottom of the stirring plate 9 is narrower than the top, after the stirring is completed, adjust the bottom of the stirring plate 9 vertically downward to accelerate the downward sliding of the concrete on the surface of the stirring plate 9.

[0038] As Figure 5 shown, a sealing ring 16 is fixedly installed on the rotating pipe 2, and the sealing ring 16 is arranged on one side of the bevel gear two 8. By arranging the sealing ring 16, when the bevel gear two 8 rotates, it prevents concrete from leaking into the contact part between the rotating pipe 2 and the bevel gear two 8.

[0039] As Figure 2As shown, one side of the stirring plate 9 close to the stirring barrel 1 is arc-shaped, and the arc-shaped protruding part of the stirring plate 9 is in contact with the inner wall of the stirring barrel 1. When the stirring plate 9 rotates, the arc-shaped protruding part on one side of the stirring plate 9 contacts the inner wall of the stirring barrel 1, and the inner wall of the stirring barrel 1 is scraped during the rotation of the stirring plate 9, so that the concrete on the inner wall of the stirring barrel 1 falls off, avoiding long-term adhesion.

[0040] For the technical solution provided by the present utility model, when using this device, after pouring the admixture from the feed port at the top of the top cover 4, when it is necessary to stir the concrete mixture inside the stirring barrel 1, start the first motor 3 to drive the rotating tube 2 to rotate. The rotating tube 2 drives the second bevel gear 8 and the stirring plate 9 to rotate. Since the rotating shaft 6 does not rotate when the second motor 5 is not started, the outer wall of the second bevel gear 8 meshes with the outer wall of the first bevel gear 7. The second bevel gear 8 rotates while revolving around the rotating shaft 6, so that the stirring plate 9 revolves around the rotating shaft 6 and rotates around the central axis of the second bevel gear 8 at the same time, thereby stirring the mixture inside the stirring barrel 1. Start the second motor 5 to drive the rotating shaft 6 and a plurality of first bevel gears 7 to rotate. The first bevel gear 7 drives the meshing second bevel gear 8 to rotate, and the second bevel gear 8 drives the stirring plate 9 to rotate. After stirring, after the mixture in the stirring barrel 1 is discharged, start the second motor 5 to drive the rotating shaft 6 to rotate. The first bevel gear 7 drives the second bevel gear 8 and the stirring plate 9 to rotate until the narrower side of the stirring plate 9 faces downwards. When the stirring plate 9 rotates inside the stirring barrel 1, during the rotation of the stirring plate 9, the metal beads 11 move inside the movable groove 10, and the metal beads 11 collide with the inner wall of the movable groove 10, causing the stirring plate 9 to vibrate. When the stirring plate 9 rotates to one side of the magnet 12, the magnet 12 attracts the metal beads 11. When the stirring plate 9 moves away from the magnet 12, the metal beads 11 fall freely. After stirring, after the mixture inside the stirring barrel 1 is discharged, the stirring plate 9 continues to rotate, so that the mixture on its surface continues to fall off due to the vibration of the stirring plate 9. When it is necessary to remove and replace the magnet 12, hold the handle 13 and pull out the magnet 12 upwards. Since the rotating shaft 6 and the rotating tube 2 rotate relative to each other, the fixed disk 14 supports the limit disk 15 and the rotating shaft 6.

[0041] The present utility model covers any substitutions, modifications, equivalent methods and solutions made on the essence and scope of the present utility model. In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the above preferred embodiments of the present utility model. However, those skilled in the art can fully understand the present utility model without these detailed descriptions.

[0042] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
