Technical Field

[0002] Concrete additives are chemical substances added during the mixing of concrete, accounting for less than 5% of the cement mass, which can significantly improve the performance of concrete. The characteristics of concrete additives are that there are many varieties and small dosage, and they have a great impact on the performance of concrete, with low investment, quick results, and significant technical and economic benefits. With the continuous advancement of science and technology, additives have been increasingly used, and additives have become the fifth important component of concrete in addition to the four basic components. Additives have a certain improvement effect on the carbonation resistance of concrete, and there is a certain linear relationship between the carbonation depth and porosity of concrete; additives have a great influence on the frost resistance of concrete. Concrete mixed with air-entraining water-reducing agent has better frost resistance, while the addition of early strength agent alone has no improvement effect on the frost resistance of concrete.

[0003] Existing devices, such as a feeding mechanism for concrete additive production shown in the authorization publication number CN213133095U, include a feeding hopper, and a plate shell is fixedly installed on one side of the inner wall of the feeding hopper. Although the above patent can prevent the concrete additive from being blocked during feeding, it does not have a quantitative function, resulting in the concrete additive raw material being added and mixed, due to inaccurate dosage, resulting in the production of low quality or unqualified concrete additive products.

[0004] Therefore, we propose a quantitative feeding mechanism for concrete additive production to solve the above problems. Utility Model Content

The gear 10 is driven to rotate by the motor 11, and the tooth plates 9 are cooperated to realize the reverse movement of the two sliding plates 8, so as to realize the quantitative addition of additives between the upper and lower sliding plates 8. Compared with the existing device, it avoids the situation that the quality of the finished product of the concrete additive is low or unqualified due to inaccurate dosage, thereby improving the production quality of the additive.

[0022] Reference Figure 2-3 The lower end of the inner wall of the box body 1 is funnel-shaped, and a discharge pipe 13 is provided at the bottom end of the box body 1. A valve 14 is installed at the bottom end of the discharge pipe 13. The funnel-shaped inner wall of the box body 1 can facilitate the discharge of raw materials and can realize the upward flipping of raw materials when stirring the raw materials, thereby improving the uniformity of the stirring of the raw materials.

[0023] The stirring assembly includes a spiral auger 15 fixedly connected to the lower end of the rotating shaft 2. The side of the spiral auger 15 is in contact with the side wall of the discharge pipe 13. The spiral auger 15 can be used to facilitate the discharge of raw materials. In addition, while stirring the raw materials, the rotation of the spiral auger 15 can move the raw materials in the feeding pipe 6 upward.

[0027] Working principle:

[0028] The quantitative feeding mechanism for concrete additive production, when in use, adds the main raw material of concrete additive into the box body 1 through the feeding pipe 5, and then adds the auxiliary raw material into the feeding pipe 6, at this time, the motor 11 is turned on and the gear 10 is driven to rotate, thereby driving the two tooth plates 9 and the two sliding plates 8 to move in the opposite direction, at this time, the sliding plate 8 located at the top moves toward the installation box 7, and the auxiliary raw material falls between the two sliding plates 8, when one end of the sliding plate 8 located at the top is flush with the side wall of the feeding pipe 6, the motor 11 is reversed to drive the gear 10 to rotate in the opposite direction, and the sliding plate 8 located at the top gradually moves toward the slot 1 2 until one end is inserted into the slot 12. At the same time, the sliding plate 8 located below gradually moves toward the installation box 7 until one end is flush with the side wall of the feeding pipe 6. At this time, the auxiliary raw materials between the two sliding plates 8 can be quantitatively added into the box body 1. At this time, the motor 3 is turned on to drive the rotating shaft 2 to rotate, the stirring plate 4 drives the raw materials to stir, and the spiral auger 15 turns the raw materials upward. After the production is completed, the valve 14 is opened, the motor 3 is reversed and the spiral auger 15 is driven to rotate to discharge the raw materials downward. The above is the entire use process of the quantitative feeding mechanism for concrete additive production.
