Description

Technical Field

[0001] The utility model relates to the field of concrete, in particular to a device for uniformly stirring multi-component mineral admixture concrete. Background Art

[0002] Mineral admixtures refer to inorganic mineral fine powders added during concrete preparation to improve the performance of fresh concrete and hardened concrete. Usually, the amount of mineral admixtures added is greater than 5% of the amount of cement, and the fineness is the same as or finer than that of cement. Mineral admixtures include fly ash, granulated blast furnace slag, silica fume, limestone powder, steel slag powder, phosphorus slag powder, zeolite powder, and composite mineral admixtures. When using mineral admixtures, the concrete needs to be mixed more carefully and fully to ensure the performance of the concrete. Utility Model Content

[0003] Purpose of the utility model: The technical problem to be solved by the utility model is to provide a device for uniformly mixing multi-mineral admixture concrete in view of the deficiencies in the prior art.

[0004] In order to solve the above technical problems, the utility model discloses a device for uniformly mixing multi-mineral external admixture concrete, including a mixing drum, which is horizontally placed, and the inner wall of the mixing drum is provided with an external spiral mixing groove, and the first bearing mounting seat and the second bearing mounting seat are respectively provided on both sides of the interior of the mixing drum, and the first bearing mounting seat is installed on the first bearing mounting seat, and the second bearing is installed on the second bearing mounting seat. A mixing motor is provided at one end of the outer side of the mixing drum, and the mixing motor drives a mixing shaft, which passes through the first bearing and is connected to the second bearing, and an inner spiral mixing shaft is provided on the mixing shaft.

[0005] In the utility model, more than two groups of electric rollers are arranged at the bottom of the mixing drum.

[0006] In the utility model, an openable and closable material port is provided at one end of the mixing drum away from the mixing motor.

[0007] In the utility model, the stirring drum rotates in opposite directions to the stirring shaft.

[0008] Beneficial effect: Based on the traditional mixing drum, the utility model adopts a built-in mixing shaft to drive the inner spiral mixing shaft, and uses gravity, an outer spiral mixing tank and an inner spiral mixing shaft to fully mix the concrete, thereby ensuring uniform mixing of the multi-mineral admixture concrete.

DETAILED DESCRIPTION

[0012] Example:

[0013] like Figure 1 The present embodiment provides a uniform mixing device for multi-component mineral admixture concrete, comprising a mixing drum 1, the mixing drum is horizontally placed, an outer spiral mixing groove 2 is provided on the inner wall of the mixing drum, a first bearing mounting seat 3 and a second bearing mounting seat 4 are provided on both sides of the inside of the mixing drum, a first bearing 5 is installed on the first bearing mounting seat, and a second bearing 6 is installed on the second bearing mounting seat, a mixing motor 7 is provided at one end of the outer side of the mixing drum, the mixing motor drives a mixing shaft 8, the mixing shaft passes through the first bearing and is connected to the second bearing, and an inner spiral mixing shaft 9 is provided on the mixing shaft. Two or more sets of electric rollers 10 are provided at the bottom of the mixing drum. An openable and closable material port 11 is provided at one end of the mixing drum away from the mixing motor. The mixing drum rotates in opposite directions to the mixing shaft.

[0014] When the present embodiment is in use, the multi-mineral admixture and various concrete raw materials are introduced into the mixing drum 1 through the material port 11. During mixing, the electric roller 10 is turned on to drive the mixing drum 1 to rotate, and then the mixing shaft 8 is driven to rotate in the opposite direction by the mixing motor 7, so that the outer spiral mixing tank 2 of the mixing drum and the inner spiral mixing shaft 9 rotate in the opposite direction. Under the action of gravity, the concrete is evenly mixed under the action of the outer spiral mixing tank 2 and the inner spiral mixing shaft 9.

[0015] The utility model provides a concept and method for a uniform mixing device for multi-component mineral admixture concrete. There are many methods and ways to implement the technical solution. The above is only a preferred implementation of the utility model. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model. These improvements and modifications should also be regarded as the protection scope of the utility model. All components not specified in this embodiment can be implemented by existing technologies.
