Description

Technical Field

[0001] This utility model relates to the field of quantitative addition technology of admixtures, specifically a quantitative addition control device for concrete admixtures. Background Technology

[0002] Concrete admixtures are substances added to concrete before or during mixing to improve its performance. These include various water-reducing agents, pumping agents, retarders, accelerators, waterproofing agents, and expanding agents. Concrete admixtures also need to be mixed in a mixing tank at many stages of production. Therefore, a quantitative addition control device is used at the concrete mixing plant.

[0003] For example, the patent publication number CN211541842U discloses a quantitative addition device suitable for the production of concrete admixtures, which includes a concrete silo, three support legs installed at the bottom of the concrete silo, and a quantitative addition device installed on the upper side of the concrete silo. The quantitative addition device includes an admixture weighing silo, an admixture storage silo, a discharge port, a control box, and a motor.

[0004] While the aforementioned device solves the problem of precise material addition, it still has the following drawbacks: due to its compositional characteristics, the liquid admixture stored in the preparation cylinder is prone to stratification within the cylinder. This stratification leads to uneven content of the admixture during discharging, which in turn affects the overall performance of the concrete and causes quality deviations. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a quantitative addition control device for concrete admixtures, which can reduce the stratification of admixtures in the preparation cylinder.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quantitative addition control device for concrete admixtures, comprising a quantitative addition equipment body and a material preparation cylinder connected to the quantitative addition equipment body. The top surface of the material preparation cylinder is open, and an installation ring is installed on the top of the material preparation cylinder. A crossbeam is fixedly connected to the middle position of the installation ring, and multiple aeration pipes are fixedly connected to the bottom surface of the crossbeam. Multiple aeration holes are opened on the aeration pipes. A gas pipe is installed on one side of the outer wall of the installation ring. One end of the gas pipe is connected to a first solenoid valve, and the outer end of the first solenoid valve is connected to a gas generating device through an external pipe. The gas generating device sends gas through the external pipe, the first solenoid valve, the gas pipe, the installation ring, and the crossbeam into the multiple aeration pipes.

[0007] Furthermore, an L-shaped tube is fixedly connected to the outer wall of the aeration pipe. The L-shaped tube is bent downwards and connected to the aeration pipe. Multiple aeration holes are opened on the L-shaped tube.

[0008] Furthermore, the aeration pipe can also be designed to bend upwards.

[0009] Furthermore, a water pipe is connected to the outer wall of the mounting ring, and a second solenoid valve is connected to the outer end of the water pipe. The outer end of the second solenoid valve is connected to a water source pumping device through an external pipe.

[0010] Furthermore, the top surface of the mounting ring is rotatably connected to two symmetrically arranged cover plates, each of which is connected to a breathable layer for ventilation.

[0011] Furthermore, a fixing plate is fixedly connected to the top surface of the crossbeam, and magnetic plates are fixedly connected to both sides of the outer wall of the fixing plate. Iron plates corresponding to the magnetic plates are fixedly connected to the inner walls of the two cover plates.

[0012] Furthermore, the mounting ring and the material preparation cylinder are connected by a snap-fit ​​mechanism.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention utilizes multiple aeration pipes installed inside a preparation cylinder containing admixtures. Gas is transported through these pipes to aerate the liquid admixture, promoting continuous turbulence and achieving excellent mixing and homogenization. This method effectively prevents stratification caused by static placement of the admixture, ensuring its uniform and stable composition. This guarantees precise subsequent addition and the stability of concrete performance. The structure is simple, easy to operate, and highly practical. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figures 1 to 4 As shown, a quantitative addition control device for concrete admixtures includes a quantitative addition equipment body 1 and a material preparation cylinder 2 connected to the quantitative addition equipment body 1. The top surface of the material preparation cylinder 2 is open, and an installation ring 3 is installed on the top of the material preparation cylinder 2. A crossbeam 14 is fixedly connected to the middle position of the installation ring 3. Multiple aeration pipes 10 are fixedly connected to the bottom surface of the crossbeam 14. Multiple aeration holes are opened on the aeration pipes 10. A gas pipe 5 is installed on one side of the outer wall of the installation ring 3. One end of the gas pipe 5 is connected to a first solenoid valve 6. The outer end of the first solenoid valve 6 is connected to a gas generating device through an external pipe. The gas generating device sends gas through the external pipe, the first solenoid valve 6, the gas pipe 5, the installation ring 3, and the crossbeam 14 into the multiple aeration pipes 10.

[0022] like Figure 1 As shown, the concrete admixture quantitative addition control device of this utility model is structurally similar to existing quantitative addition devices for concrete admixture production, such as the quantitative addition device for concrete admixture production disclosed in patent publication number CN211541842U. The main improvement of this utility model is that it can reduce the stratification phenomenon of admixtures in the preparation cylinder, such as... Figures 1 to 4 As shown, in the present invention, when the concrete admixture quantitative addition control device is in use, the admixture in the preparation cylinder 2 enters the quantitative addition device body 1 and is weighed, and then is smoothly added to the concrete silo.

[0023] After the additive has been added to the preparation cylinder 2, the first solenoid valve 6 can be opened by the existing PLC controller, and the external gas generating equipment can be started at the same time. The gas generating equipment can be an existing air compressor or other equipment. The gas generating equipment sends gas into multiple aeration pipes 10 through the external pipe, gas pipe 5, mounting ring 3, and crossbeam 14. Aeration holes are opened on the aeration pipes 10 to tumble the additive.

[0024] It should be noted that cavities should be provided inside the mounting ring 3 and the crossbeam 14, such as... Figure 2 As shown in the cross-sectional view, each aeration pipe 10 is connected to the crossbeam 14, thus ensuring that gas can smoothly enter multiple aeration pipes 10.

[0025] By setting multiple aeration pipes 10 inside the preparation cylinder 2 containing the admixture, the aeration pipes 10 are located inside the admixture and aerated by the gas transportation, causing the liquid to tumble and achieve a mixing effect, effectively reducing the stratification phenomenon of the admixture.

[0026] like Figure 2 , Figure 3 and Figure 4As shown, an L-shaped tube 11 is fixedly connected to the outer wall of the aeration pipe 10. The L-shaped tube 11 is bent downwards and is connected to the aeration pipe 10. Multiple aeration holes are opened on the L-shaped tube 11.

[0027] Specifically, in order to improve the aeration effect, an L-shaped pipe 11 is added to the outside of the aeration pipe 10, which allows the aeration pipe 10 and the L-shaped pipe 11 to aerate the admixture more fully, resulting in better liquid tumbling and mixing.

[0028] like Figure 4 As shown, the aeration pipe 10 can also be configured to be bent upwards.

[0029] Specifically, the L-shaped tube 11 can be bent upwards, which allows the L-shaped tube 11 to be immersed more deeply in the liquid, thereby improving the aeration effect and further enhancing the mixing effect.

[0030] like Figure 2 and Figure 3 As shown, a water pipe 7 is also connected to the outer wall of the mounting ring 3. The outer end of the water pipe 7 is connected to a second solenoid valve 8. The outer end of the second solenoid valve 8 is connected to a water source pumping device through an external pipe.

[0031] Specifically, to facilitate cleaning inside the material preparation cylinder 2, the second solenoid valve 8 can be activated by the existing PLC controller, while the first solenoid valve 6 is closed. This keeps the gas pipe 5 in a closed state. After the second solenoid valve 8 is opened, the water pipe 7 is connected, allowing an external water source to be pumped into the equipment. The cleaning water is then sent through the water pipe 7 into the mounting ring 3, crossbeam 14, aeration pipe 10, and L-shaped pipe 11. This not only cleans the inside of the material preparation cylinder 2 but also flushes the aeration pipe 10, preventing blockages.

[0032] The water after cleaning can either enter the main body of the quantitative addition device 1 or be discharged through the mixing hopper.

[0033] like Figure 3 and Figure 4 As shown, the top surface of the mounting ring 3 is rotatably connected to two symmetrically arranged cover plates 4, and each cover plate 4 is connected to a breathable layer 9 for ventilation.

[0034] Specifically, the cover plate 4 can prevent dust and impurities from directly entering the admixture, the air permeable layer 9 can ensure the air pressure balance in the preparation cylinder 2, and the air permeable layer 9 should also have a filtration function, thereby preventing dust and other impurities from entering the preparation cylinder 2.

[0035] like Figure 3 and Figure 4 As shown, a fixing plate 15 is fixedly connected to the top surface of the crossbeam 14, and magnetic plates 13 are fixedly connected to both sides of the outer wall of the fixing plate 15. Iron plates 12 corresponding to the magnetic plates 13 are fixedly connected to the inner walls of the two cover plates 4.

[0036] Specifically, in order to allow the cover plate 4 to be opened for easy replenishment of additives, the cover plate 4 can be rotated open, such as... Figure 3 As shown, after the cover plate 4 is combined, it can be magnetically fixed by the iron plate 12 and the magnetic sheet 13.

[0037] like Figure 1 and Figure 2 As shown, the mounting ring 3 and the material preparation cylinder 2 are connected by a snap-fit ​​mechanism. By providing a snap-fit ​​between the mounting ring 3 and the material preparation cylinder 2, the mounting ring 3 can be stably connected to the top of the material preparation cylinder 2. This snap-fit ​​mechanism can refer to the snap-fit ​​components in existing technologies, which are so common that they will not be described in detail here.

[0038] The gas generating device and water pumping device in the above structure are both existing common technologies. Furthermore, the PLC controller mentioned above is similar to the PLC controller in a quantitative addition device for concrete admixture production disclosed in patent announcement number CN211541842U. Therefore, the operating principles, working methods, and control methods of the gas generating device, water pumping device, and PLC controller are all existing technologies and should be common technical means well known to those skilled in the art. Therefore, they will not be described in detail here.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
