Abstract
Description
Technical Field
[0001] The utility model relates to a sediment prevention device, in particular to a sediment prevention device for concrete admixtures. Background Art
[0002] Concrete admixtures refer to substances added to improve and regulate the performance of concrete. Their application in projects has been increasingly emphasized. 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 their development.
[0003] For example: due to the availability of high-range water reducers, high-fluidity concrete, self-compacting concrete, and high-strength concrete have been applied; due to the availability of thickeners, the performance of underwater concrete has been improved; due to the availability of retarders, the setting time of cement has been extended, making it possible to reduce slump loss and extend the construction operation time; due to the availability of antifreeze agents, the freezing point of the solution has been reduced, or the ice crystal structure deformation does not cause frost damage, making it possible to construct at negative temperatures, etc.
[0004] However, after the existing concrete admixtures are mixed, the concrete admixtures are in a viscous state. After being placed for a long time, the concrete admixtures will precipitate, and then they will be in a state of separation between the admixtures and water. If directly pumped out for use, the quality of the concrete will be reduced. Therefore, a sediment prevention device for concrete admixtures is needed.
[0005] The existing sediment prevention devices for concrete admixtures mainly rely on mechanical stirring devices. The continuous stirring of the blades of the stirring device drives the slurry to flow, thereby reducing sedimentation. However, this kind of sediment prevention device still has some defects in actual application. Specifically: when continuously stirring, the sedimentation of the additives is not obvious, but it consumes a lot of electricity, and the wear rate of the stirring device is relatively fast; when not stirring usually and starting to stir during use, it is difficult for all the additives deposited at the bottom to be driven up by the water flow, resulting in a large amount of additives still deposited on the bottom plate, thereby reducing the additive concentration and affecting the quality of the concrete.
[0006] Therefore, we have improved the sediment prevention device for concrete admixtures. Summary of the Utility Model

Detailed Embodiment
[0039] The following further illustrates the present utility model in conjunction with embodiments, but it shall not be used as a basis for limiting the present utility model.
[0040] Embodiment of the present utility model
[0041] A device for preventing precipitation of concrete admixtures, as shown in the attached Figures 1-4 figure, includes a mixing barrel 2, a barrel cover 3 is arranged at the upper end of the mixing barrel 2, a suspended and swingable movable sedimentation plate 9 is arranged at the bottom inside the mixing barrel 2, the suspended height of the movable sedimentation plate 9 is 5 - 10 cm, and the movable sedimentation plate 9 is connected with a swinging mechanism; a shaft rod 4 is arranged above the movable sedimentation plate 9, a plurality of stirring rods 5 are arranged on the shaft rod 4, and the shaft rod 4 is connected with a stirring motor 7.
[0042] In use, open the bucket cover 3, add admixture and water into the mixing bucket 2 in proportion, and then cover the bucket cover 3. During the standing period, the admixture precipitates and adheres to the surface of the movable sedimentation plate 9. When the admixture is needed, start the shaking mechanism and the stirring motor 7. The shaking mechanism drives the movable sedimentation plate 9 to shake. The continuously shaking movable sedimentation plate 9 vibrates and detaches the admixture on its surface. Then, under the stirring action of the stirring rod 5, the admixture is evenly dispersed in the slurry again.
[0043] The preferred embodiment is as shown in the attached Figures 1-4 figure. The movable sedimentation plate 9 is supported by a spring 12 provided below its edge and is suspended above the bottom in the mixing bucket 2. The spring 12 can provide a reciprocating force and continuously push the movable sedimentation plate 9 to shake up and down during the shaking process of the movable sedimentation plate 9.
[0044] The preferred embodiment is as shown in the attached Figures 1-4 figure. The spring 12 is arranged in a limiting groove 10 on the side of the bottom of the mixing bucket 2, and a limiting sliding plate 11 inserted into the limiting groove 10 is provided at the edge of the movable sedimentation plate 9. When the movable sedimentation plate 9 shakes up and down, under the limiting action of the limiting groove 10 and the limiting sliding plate 11, the movable sedimentation plate 9 will not shake greatly, avoiding the problem of equipment damage caused by large-scale shaking.
[0045] The preferred embodiment is as shown in the attached Figures 1-4 figure. The shaking mechanism includes an inclined column 14 provided at the lower end of the shaft rod 4. The lower end surface of the inclined column 14 is inclined, and a sliding groove 15 is provided on the lower end surface. The plane where the bottom of the sliding groove 15 is located is consistent with the lower end surface of the inclined column 14; a sliding rod 13 is provided on the movable sedimentation plate 9, and the top end of the sliding rod 13 is in contact with the bottom of the sliding groove 15.
[0046] In this embodiment, the lower end surface of the inclined column 14 being inclined means that when the inclined column 14 is vertically downward, its lower end surface is an inclined cutting surface, and the sliding groove 15 is arranged along the edge of the inclined cutting surface. When the inclined column 14 rotates, the contact horizontal plane between the bottom of the sliding groove 15 and the top end of the sliding rod 13 changes regularly up and down, and thereby drives the movable sedimentation plate 9 to continuously shake up and down.
[0047] The preferred embodiment is as shown in the attached Figures 1-4 figure. A rolling groove 16 is provided at the top end of the sliding rod 13, and a ball 17 is provided in the rolling groove 16. The top end of the sliding rod 13 is in contact with the bottom of the sliding groove 15 through the ball 17.
[0048] The rolling groove 16 and the ball 17 are arranged in a conventional manner, aiming to reduce the friction between the sliding rod 13 and the sliding groove 15.
[0049] The preferred embodiment is as shown in the attached Figures 1-4As shown, a driven gear 6 is provided at the upper end of the shaft rod 4, and the shaft rod 4 is connected to a driving gear 8 provided on the rotating shaft of the stirring motor 7 through the driven gear 6.
[0050] The preferred embodiment is as attached Figures 1-4 As shown, the shaft rod 4 is a hollow tube with a liquid hole 18 inside, a liquid extraction port 19 is provided at the lower end, and a rotary joint 20 is provided at the top. A liquid pump 21 is connected to the rotary joint 20 through a connecting pipe 22, and a liquid outlet pipe 23 is connected to the liquid pump 21. In this embodiment, the rotary joint 20 is rotatably connected to the shaft rod 4, but there is a water seal structure on the connecting surface to avoid liquid leakage. When extracting liquid, the liquid pump 21 is started, and the admixture slurry directly flows in from the liquid extraction port 19 at the bottom of the shaft rod 4 and then is discharged from the mixing barrel 2.
[0051] The preferred embodiment is as attached Figures 1-4 As shown, the mixing barrel 2 is provided on the bottom plate 1. Movable wheels 24 are provided on the lower side of the bottom plate 1, a push-pull handle 25 is provided on the front side, and a power supply control box 26 is provided on the upper side. The power supply control box 26 in this embodiment is a conventional control box, which is to meet the requirement of being able to control and supply power to the device of the present invention.
[0052] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
