Description

Technical Field

[0001] This utility model relates to the field of concrete technology, and in particular to a device for preventing sedimentation of concrete admixtures. Background Technology

[0002] Concrete admixtures are substances added to improve and adjust the properties of concrete. The application of concrete admixtures in engineering is receiving increasing attention, and the addition of admixtures plays a certain role in improving concrete performance. However, the selection of admixtures, the method of addition, and their adaptability will seriously affect their development.

[0003] For example, Chinese patent CN219815980U discloses a concrete admixture anti-settling device. In this solution, the compressed air has a certain pressure and a certain impact force, which can blow the concrete admixture at the bottom of the storage tank. Combined with the mixing mechanism and the air filling mechanism, it can ensure that the concrete admixture in the storage tank is in a state of continuous churning, which can effectively prevent the concrete admixture from settling and ensure the quality of the concrete admixture.

[0004] However, in the aforementioned disclosed technical solutions, although the compressed air from the air pump has a certain pressure and impact force, capable of blowing the concrete admixture at the bottom of the storage tank, and combined with the mixing mechanism and the air-filling mechanism, it can ensure that the concrete admixture in the storage tank is in a state of continuous turbulence, effectively preventing sedimentation. However, during the mixing process, when the concrete admixture is blown up by the air-filling mechanism, the concrete admixture falling into the bottom of the discharge pipe is prone to sedimentation. Therefore, during the anti-settling mixing process, the admixture in the discharge pipe cannot achieve a good mixing effect. Therefore, it is necessary to invent a concrete admixture anti-settling device to solve the above problems. Utility Model Content

[0006] A concrete admixture anti-settling device includes a support platform, a vessel body, and a lifting assembly. The vessel body is installed through the support platform. A feed hopper is connected through the top surface of the vessel body. A filter plate is fixedly connected to the inner wall of the vessel body. A guide tube is connected to the bottom end of the vessel body. A filter cylinder is fixedly connected inside the guide tube.

[0007] A protective cover is fixedly connected to the top of the vessel. A motor is installed on the top surface of the protective cover. The bottom end of the motor passes through the inside of the protective cover and is connected to a rotating rod. A gear A is fixedly connected to the bottom of the rotating rod. A gear B is meshed with one side of the gear A. A rotating cylinder is fixedly installed inside the gear B. Stirring blades are fixedly installed at equal intervals on the outside of the rotating cylinder. A first scraper is sleeved on the bottom of the rotating cylinder. The bottom surface of the first scraper abuts against the surface of the filter plate.

[0008] The lifting assembly includes a bevel gear A, which is sleeved on the outside of a rotating rod. A bevel gear B is meshed with the top of bevel gear A. A rotating rod is fixedly connected to one side of bevel gear B. A disc is fixedly connected to one side of the rotating rod. A movable wheel abuts against the inner wall of the disc. A connecting block is fixedly connected to one side of the movable wheel. An mounting block is sleeved on the outside of the rotating rod. The mounting block is fixedly connected to a fixed plate via a mounting rod. A sliding rod is slidably connected to the inside of the fixed plate. The outside of the sliding rod is slidably disposed inside the connecting block. A spring is sleeved on the outside of the sliding rod. A fixed rod is fixedly connected to the bottom of the fixed plate. A rotating rod is fixedly connected to the bottom of the sliding rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model involves collecting and filtering smaller sediments of concrete admixtures after they pass through a filter plate and filter cylinder. Then, under the action of a lifting component, the concrete admixtures that have settled to the bottom of the reactor and inside the filter cylinder are lifted up by a lifting column, so that the smaller sediments are further prevented from settling, thereby ensuring the anti-settling effect of the concrete admixture.

[0018] 2. This utility model involves stirring and mixing the concrete admixture inside the reactor. The prepared concrete admixture is first filtered through a filter plate. For concrete admixtures with large sedimentation, the mixture is stirred and mixed on the filter plate, effectively breaking up and filtering the concrete admixtures with large sedimentation.

[0028] A protective cover 5 is fixedly connected to the top of the vessel body 2. A motor 7 is installed on the top surface of the protective cover 5. The bottom end of the motor 7 passes through the inside of the protective cover 5 and is connected to a connecting shaft 8. The bottom of the connecting shaft 8 abuts against the surface of the top of the vessel body 2. A gear A9 is fixedly connected to the bottom of the connecting shaft 8. A gear B10 is meshed with one side of the gear A9. A rotating cylinder 19 is fixedly installed inside the gear B10. Stirring blades 20 are fixedly installed at equal intervals on the outside of the rotating cylinder 19. The surface of the stirring blades 20 abuts against the surface of the inner wall of the vessel body 2. A first scraper 22 is sleeved on the bottom of the rotating cylinder 19. The bottom surface of the first scraper 22 abuts against the surface of the filter plate 21.

[0029] A lifting assembly for controlling the up-and-down movement of the lifting column includes a bevel gear A11, which is sleeved on the outside of the connecting shaft 8. A bevel gear B12 is meshed with the top of bevel gear A11. When the connecting shaft 8 rotates, bevel gear B12 is restricted by bevel gear A11, thus causing bevel gear B12 to rotate. A rotating rod 28 is fixedly connected to one side of bevel gear B12, and a disc 25 is fixedly connected to one side of the rotating rod 28. An eccentric portion of one side of the disc 25 is fixedly connected to the rotating rod 28. A moving wheel 26 abuts against the inner wall of the disc 25, and a connecting block 27 is fixedly connected to one side of the moving wheel 26.

[0030] The implementation principle of the concrete admixture anti-settling device in this application embodiment is as follows: When using this utility model, the concrete admixture is poured into the feed hopper 4, and then the motor 7 drives the connecting shaft 8 to start the rotating drum 19. The stirring blades 20 sleeved on the outside of the rotating drum 19 and the first scraper 22 sleeved on the bottom start to move, so that the concrete admixture entering the reactor 2 starts to stir. The prepared concrete admixture is first filtered through the filter plate 21. For concrete admixture with large sedimentation, it continues to be stirred and mixed on the filter plate 21. Then, the bevel gear A11 drives the bevel gear B12 to rotate. The rotating rod 28 inside the bevel gear B12 drives the disc 25 to move, so that the moving wheel 26 connected to the connecting block 27 inside the disc 25 moves up and down, which drives the rotating rod 24 at the bottom of the slide rod 16 to move up and down, and drives the concrete admixture lifting column 29 that has settled to the bottom of the reactor 2 and inside the filter cylinder 23 to rise, so that the smaller sediments are further prevented from settling, effectively avoiding the formation of concrete admixture sedimentation.
