Description

Technical Field

[0001] The invention relates to the technical field of concrete production, in particular to an automatic admixture adding device for a concrete tank truck. Background Art

[0002] Concrete has the characteristics of abundant raw materials, low price and simple production process, so its usage is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability and a wide range of strength grades, which makes its application range very wide. Concrete admixture refers to the substance added to improve and adjust the performance of concrete. The addition of concrete admixture can play a certain role in improving the performance of concrete.

[0003] During the use of the existing automatic admixture adding device, due to long-term static state, the admixture solution will precipitate, resulting in changes in admixture concentration and performance, which will affect the quality of concrete. At the same time, additive residues will adhere to the inner wall of the storage tank of the existing automatic admixture adding device, resulting in changes in concentration during the admixture addition process. Moreover, the solubility of some concrete admixtures will change with temperature. When the temperature drops in winter, crystals are easily precipitated in the solution, affecting the addition accuracy of the admixture, which will affect the quality of concrete.

[0030] In order to make the automatic admixture adding device for concrete tank truck have the effect of improving the fusion uniformity of admixture solution, making the automatic admixture adding device for concrete tank truck have the effect of preventing admixture residue from adhering to the inner wall of tank body 1, and making the automatic admixture adding device for concrete tank truck have the effect of ensuring the internal temperature balance of admixture storage tank body 1, ensuring the concentration of admixture solution, and improving the accuracy of admixture addition, as shown in the attached Figure 1-7 As shown, the present application adopts the following structure, through the transmission shaft 3, the connecting horizontal plate 4, the supporting vertical plate 5, the rotating shaft 6, the stirring frame 7, the first bevel gear 8, the transmission cylinder, the second bevel gear 10 and the turbine blade 15, the limit frame 18, the cleaning scraper 19 and the first spring 20, the temperature sensor 17 and the electric heating tube 21. During use, the corresponding additive solution is adjusted to the inside of the tank body 1 through the feed port 22. After the addition is completed, the cover plate is buckled. When it is necessary to add additives to the inside of the concrete tank truck, the driving motor is controlled to rotate, thereby driving the transmission shaft 3 to rotate, driving the connecting horizontal plate 4 and the supporting vertical plate 5 to rotate, and the liquid is horizontally stirred. The support plate 5 rotates, the rotating shaft 6 and the first bevel gear 8 roll along the second bevel gear 10, thereby driving the rotating shaft 6 and the stirring frame 7 to rotate. Under the action of the stirring frame 7, the solution is vertically stirred. At the same time, the rotation of the transmission shaft 3 drives the connecting shaft 14 and the turbine blades 15 to rotate, so that the solution at the bottom is extracted to the upper end of the tank body 1 through the transmission cylinder, and the rotation of the stirring frame 7 is coordinated to make the inside of the tank body 1 evenly mixed to prevent the admixture solution from settling. After completion, the electric valve 25 is opened, and the mixed liquid is added to the inside of the tank truck feed hopper 24 through the discharge pipe 23, and then enters the concrete tank truck. When the connecting cross plate 4 rotates, the limit frame 18 and the cleaning scraper 19 are driven to rotate, so that the cleaning scraper 19 scrapes the inner wall of the tank body 1 (when the cleaning scraper 19 abuts against the inner wall of the tank body 1, the first spring 20 is in a squeezed state, thereby ensuring that the cleaning scraper 19 is always in close contact with the inner wall of the tank body 1) to prevent the residue of the additive from adhering to the inner wall of the tank body 1. When the temperature sensor 17 inside the tank body 1 senses that the temperature of the liquid inside the tank body 1 is lower than the predetermined value, the corresponding temperature signal is transmitted to the external control panel, and the corresponding user controls the operation of the electric heating tube 21 to heat the tank body 1. Through heat transfer, the temperature of the solution inside the tank body 1 is increased to prevent crystals from appearing in the solution. When the temperature reaches a predetermined value, the operation of the electric heating tube 21 is stopped. When the liquid level of the solution inside the tank body 1 is lower than the liquid level sensor 16, the liquid level sensor 16 sends a corresponding liquid level signal to the external control panel to remind the corresponding user to add the solution, thereby enabling the automatic admixture adding device for the concrete tank truck to improve the fusion uniformity of the admixture solution, prevent the admixture residue from adhering to the inner wall of the tank body 1, and ensure the temperature balance inside the admixture storage tank body 1, ensure the concentration of the admixture solution, and improve the accuracy of admixture addition.
