[0002] The research and development of special composite admixtures for low-carbon concrete can not only reduce the energy and resource consumption of concrete throughout its life cycle, but also reduce its impact on the environment. Therefore, it is very necessary to carry out the research and development of low-carbon concrete.

[0003] During the research and development process of low-carbon concrete, it is necessary to quantitatively add its internal components. According to comparative experiments of different components, the concrete admixture components with the best effect and the most expected advantages can be obtained. According to a mixing device with a concrete quantitative feeding function disclosed in Chinese Patent Publication No. CN214925777U, the patent overlaps the first feeding port and the second feeding port so that the raw materials can fall. After setting the size of the first feeding port, quantitative feeding of different raw materials can be achieved, which has certain practicality. However, there is still room for improvement in the quantitative feeding method of the patent. In actual application, the patent cannot weigh the falling raw materials, and the feeding rate cannot be conveniently changed during the work, so that high-precision quantitative addition cannot be achieved, resulting in its practicality to be improved. In this regard, the present application provides a quantitative addition device for admixtures used in the research and development of low-carbon concrete admixtures to solve the above problems.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0030] See also Figure 1-4 The present application provides a technical solution: a quantitative addition device for admixtures used in the research and development of low-carbon concrete admixtures, comprising a mixing barrel 1, a quantitative addition component 200 for quantitatively adding admixtures is installed on the top of the mixing barrel 1, and a storage component 300 for storing various admixtures is installed on the top of the mixing barrel 1; through the coordinated use of the quantitative addition component 200 and the storage component 300 on the top of the mixing barrel 1, the weight of the added admixture can be monitored in real time, so that the accuracy of the admixture addition amount is high, and at the same time, the admixture can be slowly dropped, thereby reducing the error amount, so that various admixture components can be added according to the preset ratio, which is conducive to the normal development of low-carbon concrete admixtures and effectively improves the practicality of the quantitative addition device for admixtures.

[0031] In this embodiment, the quantitative addition component 200 is a structure for adding various constituent raw materials quantitatively and relatively accurately.

[0032] like Figure 1 , Figure 2 and Figure 4As shown, the quantitative addition component 200 includes a plurality of fixed boxes 201 fixed on the top of the mixing barrel 1 and an inlet pipe 206 located above the plurality of fixed boxes 201, a plurality of telescopic rods 202 fixedly installed on the inner bottom wall of the fixed box 201, an addition box 203 slidably connected to the inside of the fixed box 201, a plurality of weighing sensors 204 abutting against the bottom of the addition box 203, a discharge pipe 205 fixed to the bottom of the addition box 203, an electric valve 207 fixedly installed on the outside of the inlet pipe 206, a conical pipe 208 fixed to the bottom end of the discharge pipe 205, and a plurality of baffles 209 fixed to the inside of the inlet pipe 206.

[0033] It should be noted that four telescopic rods 202 are fixedly installed on the inner bottom wall of each fixed box 201, and four weighing sensors 204 are arranged inside each fixed box 201. The bottom of the weighing sensor 204 is fixedly connected to the inner bottom wall of the corresponding fixed box 201, and the top of the telescopic rod 202 is fixedly connected to the bottom of the corresponding adding box 203, so that the adding box 203 can move up and down in a straight line under the positioning action of the corresponding four telescopic rods 202, so that it can be stably and accurately weighed by the weighing sensor 204.

[0034] In addition, if Figure 3 As shown, four baffles 209 are fixedly connected to the inner side of each inlet pipe 206, and the corresponding four baffles 209 are symmetrically distributed on the left and right. The baffles 209 are tilted downward and have a smooth surface, so that the baffles 209 can play a certain blocking role on the descending admixture, so that the descending rate can be delayed, and the addition work with higher precision can be achieved.

[0035] In this embodiment, the storage assembly 300 is a structure for storing various admixtures.

[0036] like Figure 1 As shown, the storage assembly 300 includes four support rods 301 fixed on the top of the mixing barrel 1, a support platform 302 fixed between the top ends of the four support rods 301, a plurality of loading barrels 303 fixedly installed on the top of the support platform 302, a plurality of through holes 304 opened at the bottom of the support platform 302 for the corresponding inlet pipes 206 to be placed, a flow hole 305 opened at the top of the adding box 203 for the conical pipe 208 to pass through and slide, and a plurality of sliding holes 306 opened at the top of the mixing barrel 1 for the corresponding discharge pipes 205 to pass through.

[0037] It should be noted that the number of loading barrels 303, fixed boxes 201, entry tubes 206, through holes 304 and sliding holes 306 is equal, and the top of the entry tube 206 is fixedly connected to the bottom of the corresponding loading barrel 303, so that the admixture inside the loading barrel 303 can enter the interior of the entry tube 206. The number of loading barrels 303 is four, and the loading barrels 303 are evenly distributed on the top of the support platform 302, so that the four loading barrels 303 can respectively hold four different admixtures.

[0038] In addition, the inner diameter of the top end of the conical pipe 208 is larger than the inner diameter of the bottom end, and the bottom end of the conical pipe 208 extends to the interior of the corresponding addition box 203 through the corresponding flow hole 305, so that the admixture inside the conical pipe 208 can enter the interior of the addition box 203.

[0039] At the same time, the bottom end of the discharge pipe 205 passes through the bottom of the corresponding fixed box 201 and the interior of the sliding hole 306 and extends to the interior of the mixing barrel 1. A solenoid valve is fixedly installed on the outside of the discharge pipe 205. The solenoid valve can control the switch of the discharge pipe 205, so that the internal admixture can be normally transported to the interior of the mixing barrel 1. At the same time, the discharge pipe 205 is only fixed to the bottom of the addition box 203, and will not affect the weighing sensing work of the weighing sensor 204.

[0040] It should also be noted that in the specific research and development of low-carbon concrete, it is necessary to collect admixtures and industrial waste from different channels, and conduct cluster analysis according to the distribution areas of various mineral admixtures in the ternary phase diagram, explore their activation mechanism, and compound a high-aluminum-high-calcium-multi-component composite admixture system by adjusting the composition ratio of each admixture, and optimize the composition of the system. Through experiments, the influence of admixtures with different particle group characteristic parameters on the physical and mechanical properties of cement is explored, and the contribution relationship of particle activity and strength within each particle size range of the admixture particle group distribution is tested, so as to determine the mass ratio of each admixture in the composite mineral admixture, and judge by the ball milling effect after compounding in different proportions, so as to select the best solution.

[0041] The working principle of the above embodiment is:

[0042] When conducting research and development of low-carbon concrete admixtures, various types of admixture raw materials are placed in the interior of each loading barrel 303, and the electric valve 207 is started, so that the admixture inside the loading barrel 303 is discharged into the interior of the corresponding addition box 203 through the inlet pipe 206 and the tapered pipe 208. Under the action of the baffle 209, the flow of the admixture raw materials can be blocked to a certain extent, so that it can enter the interior of the addition box 203 in a relatively gentle posture. Under the action of the weighing sensor 204, the total weight of the addition box 203 can be monitored. When the monitored value is close to the preset value, the electric valve 207 is controlled to change the internal flow space of the inlet pipe 206, so as to achieve the effect of reducing the flow rate, so that the admixture raw materials can enter the interior of the addition box 203 in small quantities, and the addition of various types of admixtures can be completed quantitatively, which is convenient for research and development through different admixture component ratios.

[0043] Compared with the prior art, the admixture quantitative addition equipment for the research and development of low-carbon concrete admixtures can monitor the weight of the added admixture in real time through the coordinated use of the quantitative addition component 200 and the storage component 300 on the top of the mixing barrel 1, so that the accuracy of the admixture addition amount is high, and at the same time, the admixture can be slowly dropped, thereby reducing the error amount, so that various admixture components can be added according to the preset ratio, which is conducive to the normal progress of the research and development of low-carbon concrete admixtures, and effectively improves the practicability of the admixture quantitative addition equipment, and solves the shortcoming that the existing concrete quantitative feeding equipment cannot accurately add raw materials quantitatively.

[0044] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The provision of power supply is common knowledge in the field. The main controller can be a conventional known device for control such as a computer, which can be realized through simple programming by technicians in the field. They are all existing public power connection technologies and will not be described in detail in the article.
