Technical Field

[0001] The utility model relates to the technical field of concrete admixture production, in particular to an admixture premixing device. Background Art

[0002] Concrete admixtures, also referred to as admixtures, are substances added during the concrete mixing process to improve the performance of concrete. These admixtures can significantly improve the workability, strength, durability and other properties of concrete, while also reducing the amount of cement and improving construction efficiency. During the production of admixtures, multiple raw materials need to be mixed together, so a premixing device is required to stir and mix the multiple raw materials.

[0003] When currently used, the existing premixing device can usually only mix one type of admixture. If multiple admixtures need to be mixed, such as the production of powdered admixtures and liquid admixtures at the same time, additional equipment is required, or the processing of one admixture must be completed before processing another admixture. This will delay the efficiency of admixture production, and the additional equipment will increase cost expenditure. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 5 In an embodiment of the utility model, an admixture premixing device includes a support frame 1, a support shaft 2 with both ends open is rotatably penetrated between two opposite side surfaces of the support frame 1, gears 2 21 are fixedly connected at both ends of the outer wall of the support shaft 2, a plurality of mixing barrels 3 are arranged at equal angles in a ring between the two gears 21, a pipe shaft 31 which is connected to the inside of the mixing barrel 3 at a corresponding position and rotates through the gears 2 21 at the corresponding position is fixedly connected at both ends of the mixing barrel 3, a connecting pipe 34 is arranged in the pipe shaft 31, one end of the connecting pipe 34 is located at the inner bottom of the mixing barrel 3 at the corresponding position, the other end of the connecting pipe 34 penetrates the inner wall of the support shaft 2 and extends from the inside of the support shaft 2 to the outside, and a plurality of baffles are fixedly arranged at equal angles in a ring on the inner wall of the mixing barrel.

[0022] Specifically, if a is the loading direction and b is the unloading direction, firstly, the raw materials are poured into the mixing barrel 3 through the loading mechanism (the raw materials can be pumped into the mixing barrel 3 through a pump); if a liquid admixture is to be produced and the production volume is relatively large, the raw materials can be poured into two or more mixing barrels 3, and the model status of the admixture is marked on the outer wall of the mixing barrel 3; if a powdered admixture is to be produced, the raw materials are poured into several other mixing barrels 3 (specifically, the number of mixing barrels 3 can be selected according to actual production needs. For example, when a liquid admixture is produced, two mixing barrels 3 are required, and the raw materials can be poured into the two mixing barrels 3 in equal proportions, and the same operation is performed when a powdered admixture is produced and stirred); then, the rotation of the support shaft 2 can enable the two gears 21 to drive multiple The mixing barrel 3 rotates along the axis of the support shaft 2, and the various raw materials in the mixing barrel 3 can be fully mixed through the self-rotation of the mixing barrel 3. When the various raw materials in one of the mixing barrels 3 are mixed, and the various raw materials in the other mixing barrels 3 are not completely mixed, the connecting pipe 34 at the mixing barrel 3 where the mixing is completed can be found in the unloading direction, and then the mixed additives in the mixing barrel 3 are extracted by a pump, and the other mixing barrels 3 are still rotating and flipping. The device can realize the mixing of various different types of additives at the same time through the rotation of each mixing barrel 3, thereby reducing the cost expenditure of the enterprise, and improving the production efficiency of the additive, and can realize the unloading of the mixed additive alone without delaying the mixing of the additives in other mixing barrels 3.

[0023] Embodiment 1

[0024] like Figure 1 As shown, in this embodiment, the top ends of the two opposite sides of the support frame 1 are fixedly connected with annular shells 11, and the opposite sides of the two annular shells 11 are open structures. The inner wall of the annular shell 11 is fixedly connected with a gear ring 12 near the open part, and the outer wall of the tube shaft 31 is fixedly connected with a gear three 32 meshing with the gear ring 12. The bottom ends of the opposite sides of the support frame 1 are rotatably connected with a round rod 13, and the outer wall of the round rod 13 is fixedly connected with a gear one 14 meshing with the gear two 21 at the corresponding position. The inner bottom surface of the support frame 1 is fixedly connected with a pad 15, and the top surface of the pad 15 is fixedly connected with a dual-axis motor 16, and the two output ends of the dual-axis motor 16 are respectively fixed to the round rod 13 at the corresponding positions.

[0025] In this embodiment, the two gears 14 can drive the two gears 21 to rotate through the drive of the dual-axis motor 16. The two rotating gears 21 can make the multiple mixing barrels 3 revolve along the support shaft 2, thereby achieving mixing and stirring of the multiple raw materials in the mixing barrels 3.

[0026] Embodiment 2

The outer wall of the connecting pipe 34 and the inside of the annular shell 11 at the corresponding position are fixedly connected with a switch valve 35 connected to the inside of the connecting pipe 34 at the corresponding position. A through hole 17 is opened at one end face of the annular shell 11 away from its open part and penetrates through the corresponding switch valve 35.

[0028] In this embodiment, when the multiple mixing barrels 3 revolve along the support shaft 2, the gear three 32 can rotate under the action of the ring gear 12 at the corresponding position, so that the various raw materials in the mixing barrel 3 can be mixed more quickly. By making the connecting pipe 34 into a metal material, the connecting head 2 33 can be limited to prevent the rotation of the mixing barrel 3 from driving the connecting pipe 34 to rotate together.
