Abstract
Description
Technical Field
[0001] This utility model relates to a concrete admixture synthesis device, specifically a concrete admixture feeding device, particularly a feeding device applicable to both solid and liquid admixtures. Background Technology
[0002] Basic construction projects are vital to the national economy and people's livelihood. With the continuous increase in construction projects, not only is the demand for concrete increasing, but the requirements for concrete quality are also becoming more stringent. Concrete admixtures are chemical substances added during the concrete mixing process that can significantly improve concrete performance. They can increase concrete strength, improve its fluidity and cohesiveness, control the setting speed, enhance impermeability and corrosion resistance, reduce cement usage, and so on. Concrete admixtures are an indispensable component of modern concrete preparation. Therefore, appropriate synthetic additive devices are often required during concrete processing.
[0003] Since concrete admixtures are generally divided into solid admixtures and liquid admixtures, existing concrete feeding devices are typically either single-function solid admixture feeding devices or single-function liquid admixture feeding devices. These two types of devices are not interchangeable, resulting in higher production costs and lower work efficiency for enterprises. Furthermore, existing feeding devices often result in uneven mixing of concrete and admixtures, prolonged mixing time, and low mixing efficiency, ultimately affecting the quality of the produced concrete. Utility Model Content

This invention's technical solution can handle both solid and liquid admixtures in concrete using the same device. Furthermore, it features short mixing times, more uniform mixing of concrete and admixtures, high mixing efficiency, and improved concrete production quality.

The delivery pump is connected to an admixture pipeline leading into the mixing tank body. A mixing mesh plate is provided inside the premixing tank body, and the mixing mesh plate is fixed on the premixing tank shaft and rotatable by a second motor.
[0006] The above-mentioned concrete admixture synthesis device includes a mixing tank shaft and a mixing blade that are hollow tubes. The first end of the mixing blade is connected to the mixing tank shaft, a spray hole is provided on the middle section of the mixing blade, and the tail end of the mixing blade is closed. The admixture pipeline is connected to the mixing tank shaft.
[0007] In the above-mentioned concrete admixture synthesis device, the mixing mesh plate is a sieve plate with numerous through holes.

[0009] The aforementioned concrete admixture synthesis device further includes a heating device in the premix tank.
[0010] The beneficial effects of this utility model are as follows: Compared with the prior art, the technical solution of this utility model ① can be used for the addition of both solid admixtures and liquid admixtures; ② by pre-dissolving the solid admixture in water to make it liquid, the solid admixture can be mixed with concrete more easily and more thoroughly, just like the liquid admixture, thus overcoming the defect of direct mixing of solid admixtures and concrete in the prior art and improving the mixing quality of solid admixtures and concrete; ③ through the pre-treatment of the pre-mixing tank and the use of the delivery pump, the mixing time of admixtures and concrete is shortened, the concrete and admixtures are mixed more evenly, and the mixing efficiency is improved.

[0014] The present invention will now be described in further detail with reference to the embodiments and accompanying drawings.
[0015] Reference Figure 1 , Figure 2 , Figure 3The image shows an embodiment of a concrete admixture synthesis device according to this utility model. This embodiment of the concrete admixture synthesis device includes: a concrete mixing tank 1, which includes a mixing tank body 11, a mixing tank inlet 12, and a mixing tank outlet 13. A mixing tank rotating shaft 14 is provided inside the mixing tank 1, and a mixing blade 15 is fixed on the mixing tank rotating shaft 14. The mixing tank rotating shaft 14 and the mixing blade 15 are hollow tubes. The first end 152 of the mixing blade is connected to the mixing tank rotating shaft 14, and a spray hole 151 is provided on the middle section of the mixing blade. The tail end 153 of the mixing blade is closed. The mixing tank rotating shaft 14 is rotatable and driven by a first motor 16. This embodiment also includes an admixture premixing tank 2, which is a sealable tank. The premixing tank 2 has an admixture inlet 21 and a premixing tank water inlet 22. A sealing cover 211 is provided at the admixture inlet 21. The premixing tank 2 also has an admixture outlet 23, which is connected to a delivery pump 3. The delivery pump 3 is connected to an admixture pipeline 4, which leads into the mixing tank 1. A stirring screen 24 is provided inside the premixing tank 2. The stirring screen 24 is fixed to the premixing tank shaft 25 and is rotatable by a second motor 26. The admixture pipeline 4 is connected to the mixing tank shaft 14. Thus, when the liquid admixture is applied, it is fed into the premix tank 2 through the admixture inlet 21. Depending on the situation, it can be stirred through the mixing screen 24 or not. The delivery pump 3 is started to send the liquid admixture in the premix tank 2 into the hollow tube of the mixing tank shaft 14 through the admixture pipeline 4, and then into the mixing tank body 11 through the spray hole 151 of the mixing blade 15 to mix with the concrete. When solid admixtures are applied, they are fed into the premixing tank 2 through admixture inlet 21, while liquid water is added through the premixing tank inlet 22. The mixing screen 24 continuously stirs the mixture, ensuring the solid admixtures are fully mixed and dissolved with the water. At this point, the delivery pump 3 is activated to pump the now-liquid admixtures from the premixing tank 2 through admixture pipeline 4 into the hollow tube of the mixing tank shaft 14, and then into the mixing tank body 11 through the spray holes 151 of the mixing blades 15 to mix with the concrete. Since solid admixtures are largely soluble in water, and with high-speed mixing, they become liquid. Therefore, solid admixtures are easier to mix with concrete, just like liquid admixtures, resulting in more uniform dispersion and improved mixing efficiency. In this embodiment, the stirring screen 24 has numerous mesh openings 241, the diameter of which can vary. These varying mesh openings can quickly break up clumps of solid additives, allowing the broken-up solid additives to dissolve in water more rapidly and become liquid. Of course, the stirring screen 24 in this embodiment can also be a sieve commonly used in the art. The delivery pump 3 can be a conventional pump or a pressurized liquid delivery pump, depending on the situation.
[0016] In a further embodiment, the premixing tank 2 is also equipped with an air inlet pipe 27 and an air inlet valve, which facilitates the delivery pump 3 to send the additives inside and outside the premixing tank 2 into the hollow tube of the mixing tank shaft 14 through the additive pipeline 4. An inlet valve is provided at the water inlet 22 of the premixing tank to facilitate precise control of the water inlet volume, so that the solid additives are fully mixed and dissolved with water.
[0017] In environments with low temperatures, such as cold northern regions, to ensure that solid additives are fully dissolved and mixed with water, and to improve mixing efficiency and quality, the premix tank 2 can be equipped with a heating device. This heating device can be a commonly used heating method, such as an electric heating device wrapped around the premix tank 2.
[0018] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
