Description

Technical Field

[0001] This article belongs to the technical field of concrete admixture production equipment, specifically involving a return pipeline for aluminum slurry metering and feeding. Background Technology

[0002] In the process of concrete preparation, aluminum paste is often added in order to achieve specific performance indicators. The amount of aluminum paste added has a crucial impact on the performance of concrete, and its content affects the expansion performance, setting time, and other properties of concrete.

[0003] Therefore, accurately controlling the amount of aluminum slurry entering the concrete preparation device is a key step in ensuring the stability of concrete quality. Currently, in the process of aluminum slurry metering, the conventional approach relies solely on the operator's experience and simple valve opening and closing for control. This method is not only inaccurate but also labor-intensive, and cannot meet the requirements of modern concrete production for precise aluminum slurry addition. When too much aluminum slurry enters the concrete preparation device, it will lead to the subsequent addition of aluminum slurry exceeding expectations, affecting the quality of concrete. When too little aluminum slurry enters the metering tank, it is necessary to replenish the aluminum slurry, reducing production efficiency.

[0004] The valve settings and pipeline layout in the existing system make it difficult to achieve flexible adjustment and precise control of the aluminum slurry flow rate. It is significantly insufficient in terms of protecting equipment and ensuring metering accuracy, and cannot meet the demand for precise metering of aluminum slurry in the concrete preparation process. Therefore, there is an urgent need for an aluminum slurry metering and feeding device that can effectively solve the above problems. Utility Model Content

[0005] To address the aforementioned issues, this paper proposes a reflux pipeline for aluminum slurry metering and feeding. This reflux pipeline system, from inlet to outlet, sequentially comprises an aluminum slurry mixing vessel, an aluminum slurry circulation pump, an aluminum slurry metering tank, and a concrete preparation device, all connected together. A feed valve and a shut-off valve are connected in series between the aluminum slurry circulation pump and the aluminum slurry metering tank. One end of the feed valve is connected to the aluminum slurry circulation pump via a tee connector, and the other end is connected to the reflux valve via the same tee connector. The other end of the reflux valve is connected to the top of the aluminum slurry mixing vessel. The pipeline sequentially connecting the aluminum slurry mixing vessel, aluminum slurry circulation pump, feed valve, shut-off valve, aluminum slurry metering tank, and concrete preparation device constitutes the feed pipeline, while the pipeline sequentially connecting the aluminum slurry mixing vessel, aluminum slurry circulation pump, and reflux valve constitutes the reflux pipeline.

[0006] Both the feed pipeline and the return pipeline are made of corrosion-resistant materials. The feed pipeline is constructed by sequentially running from the bottom outlet of the aluminum slurry mixing tank through the aluminum slurry circulation pump to the inlet above the aluminum slurry metering tank, and then from the bottom outlet of the aluminum slurry metering tank to the concrete preparation device. The return pipeline is formed by branch pipelines between the return valve and the inlet of the aluminum slurry mixing tank. The reasonable layout of the feed pipeline and the return pipeline ensures the smoothness and stability of aluminum slurry transportation.

[0007] The aluminum slurry metering tank is interlocked with the reflux valve, which is also interlocked with the feed valve. When the aluminum slurry metering tank reaches the metering value, the reflux valve automatically opens and the feed valve automatically closes. Through the interlocking between the equipment valves, the automation level of the production process is improved, manual operation is reduced, and the feeding efficiency and accuracy are improved.

[0008] The shut-off valve, feed valve, and return valve work together to form a parallel pipeline connection. The shut-off valve is used to cut off the flow of aluminum slurry into the aluminum slurry metering tank. The feed valve and return valve are used to switch between feeding and returning aluminum slurry, which can flexibly control the flow direction and flow rate of aluminum slurry and ensure accurate metering of aluminum slurry.

[0009] The aluminum slurry metering tank is located above the concrete preparation device. The outlet of the aluminum slurry metering tank is connected to the inlet of the concrete preparation device. Gravity is used to assist in the transportation of aluminum slurry, reducing additional transportation power consumption and improving transportation efficiency.

[0010] Beneficial effects:

[0011] By setting up feed and return pipelines, precise metering and smooth return of aluminum slurry can be achieved. When the aluminum slurry metering tank reaches the set metering value, the interlocking control of the return valve and the feed valve ensures that excess aluminum slurry can be returned to the aluminum slurry mixing tank in a timely manner through the return pipeline, avoiding waste and ensuring the accuracy of aluminum slurry metering, thereby improving the precision of aluminum slurry addition during concrete preparation.

[0012] By interlocking the metering tank with the feed valve and the return valve, the aluminum slurry feeding process is automated and precise, improving production efficiency and process stability. At the same time, after the metering reaches the standard, the return valve opens first to release pressure, and then the feed valve closes to avoid pressure shock and improve the safety of the production process.

[0013] By leveraging the synergistic effect of shut-off valves, protection valves, and return valves, as well as the parallel pipeline connection mode, flexible control of the aluminum slurry flow direction and flow rate can be achieved, thereby ensuring the accuracy of aluminum slurry metering.

[0014] By placing the aluminum slurry metering tank above the concrete preparation device and using gravity to assist in the transport of the aluminum slurry, the transport of the aluminum slurry is made smoother by utilizing the characteristics of gravity. At the same time, the use of gravity-assisted transport reduces energy consumption and avoids transport delays caused by insufficient power or transport obstructions, thereby effectively improving the transport efficiency of the aluminum slurry.

[0015] By adjusting the power of the aluminum slurry circulation pump, the conveying rate of aluminum slurry from the mixing tank to the metering tank can be precisely controlled. Combined with the opening adjustment of the shut-off valve and the feed valve, metering errors caused by flow fluctuations can be avoided, ensuring the accuracy of the aluminum slurry dosage in the concrete. At the same time, it can prevent the aluminum slurry from settling and stratifying. The aluminum slurry circulation pump continuously agitates the aluminum slurry during the conveying process, avoiding the settling of solid particles or changes in viscosity caused by static standing, thus ensuring the uniformity of the aluminum slurry.

The pipeline connecting the aluminum slurry mixing tank 1, the aluminum slurry circulation pump 2, and the return valve 7 in sequence constitutes the return pipeline. Both the inlet pipeline and the return pipeline are made of corrosion-resistant materials. The system consists of a pipeline laid sequentially from the bottom outlet of the aluminum slurry mixing tank 1, through the aluminum slurry circulation pump 2 to the upper inlet of the aluminum slurry metering tank 4, and then from the lower outlet of the aluminum slurry metering tank 4 to the concrete preparation device 3. The return pipeline forms a branch pipeline between the return valve 7 and the inlet of the aluminum slurry mixing tank 1. The aluminum slurry metering tank 4 is interlocked with the return valve 7, and the return valve 7 is interlocked with the inlet valve 6. After the aluminum slurry metering tank 4 reaches the metering point, the return valve 7 automatically opens and the inlet valve 6 automatically closes. The shut-off valve 5, the inlet valve 6, and the return valve 7 cooperate with each other to form a parallel pipeline connection. The shut-off valve 5 is used to cut off the flow of aluminum slurry into the aluminum slurry metering tank 4.

The aluminum slurry metering tank 4 is located above the concrete preparation device 3, and the lower outlet of the aluminum slurry metering tank 4 is connected to the inlet of the concrete preparation device 3.

[0022] Implementation example;

[0023] The aluminum slurry in the aluminum slurry mixing tank 1 is pumped to the aluminum slurry metering tank 4 by the aluminum slurry circulation pump 2. The shut-off valve 5 and the feed valve 6 need to be opened in advance, and the return valve 7 needs to be closed in advance. After the aluminum slurry metering tank 4 reaches the metering point, the return valve 7 is opened and the shut-off valve 5 and the feed valve 6 are closed. The aluminum slurry flows from the return pipeline into the feed port above the aluminum slurry mixing tank 1. When the concrete preparation device 3 needs to add aluminum slurry, it is pumped into the concrete preparation device 3 by the aluminum slurry metering tank 4.
