Description

Technical Field

[0002] Polycarboxylate superplasticizer is a high-performance water-reducing agent and a cement dispersant used in cement concrete. It is widely used in highways, bridges, dams, tunnels, high-rise buildings, and other projects. Polycarboxylate superplasticizers are characterized by high water reduction rate, environmental friendliness, and ease of use. However, because it is a liquid, transportation is inconvenient. Therefore, manufacturers usually only provide high-concentration superplasticizers, which are then diluted by commercial concrete plants.

[0003] Polycarboxylate superplasticizers are generally diluted with pure water. Currently, most dilution methods are achieved through mechanical stirring. The basic dilution process involves pouring high-concentration polycarboxylate superplasticizer and water into a dilution tank in a certain ratio, and then stirring and mixing them with a rotating agitator. However, this method requires a stirring agitator inside the dilution tank and a drive motor outside the tank to rotate the stirring agitator, resulting in a complex overall structure and high cost.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-2 This utility model provides a technical solution: An automatic concrete water-reducing agent preparation device includes a high-concentration water-reducing agent tank 1, a water tank 2, and a dilution tank 3. The high-concentration water-reducing agent tank 1 contains high-concentration water-reducing agent, the water tank 2 contains purified water, and the dilution tank 3 is used for mixing and diluting the high-concentration water-reducing agent and purified water. Furthermore, a sixth pipe 19 is provided on the water tank 2, and a water purifier 20 is installed on the sixth pipe 19. External water is filtered and purified by the water purifier 20 and then transported to the water tank 2 through the sixth pipe 19, ensuring the purity of the water in the water tank 2. The specific model of the water purifier 20 is not limited here.

[0017] The high-concentration water-reducing agent tank 1 is at a higher level than the dilution tank 3. The first delivery pipe is connected to the high-concentration water-reducing agent tank 1, and the high-concentration water-reducing agent can enter the interior of the dilution tank 3 through the first delivery pipe. The water tank 2 is connected to the dilution tank 3 through the second delivery pipe, and pure water enters the interior of the dilution tank 3 through the second delivery pipe. A first valve 5 and a first flow meter 6 are installed on the first conveying pipeline. The first valve 5 is used to control the opening and closing of the first conveying pipeline, and the first flow meter 6 is used to record the flow rate of the high-concentration water-reducing agent entering the dilution tank 3 so as to dilute the high-concentration water-reducing agent according to the appropriate ratio. The second conveying pipeline is equipped with a first pump body 13 and a second flow meter 18. The first pump body 13 is used to convey pure water and high-concentration water-reducing agent into the interior of the dilution tank 3, and the second flow meter 18 is used to record the flow rate of pure water entering the interior of the dilution tank 3. The first conveying pipeline is connected to the dilution tank 3 through the second pipeline 7, and a second valve 8 is installed on the second pipeline 7. The second valve 8 is used to control the opening and closing of the second pipeline 7. A plurality of first capillary tubes 21 are connected between the first conveying pipe and the second conveying pipe, and a plurality of second capillary tubes 23 are connected between the second conveying pipe and the dilution tank 3; wherein the sum of the unit flow rate of the plurality of first capillary tubes 21 and the unit flow rate of the plurality of second capillary tubes 23 is equal to the unit flow rate of the second conveying pipe.

[0018] The first conveying pipeline includes a first spiral pipe 9, and the first conveying pipeline also includes a first pipe 4 connecting the high-concentration water-reducing agent tank 1 and the first spiral pipe 9. A first valve 5 and a first flow meter 6 are installed on the first pipe 4; one end of the second pipe 7 is connected between the first flow meter 6 and the first spiral pipe 9.

[0019] The second conveying pipeline includes a second spiral tube 10, a first thin tube 21 connecting the first spiral tube 9 and the second spiral tube 10, and a second thin tube 23 connecting the dilution tank 3 and the second spiral tube 10. The first spiral tube 9 and the second spiral tube 10 are both sleeved on the outside of the dilution tank 3. The high-concentration water-reducing agent and pure water can be mixed during the flow inside the first spiral tube 9 and the second spiral tube 10. The second conveying pipeline also includes a third pipeline 11 and a fifth pipeline 17. The third pipeline 11 connects the dilution tank 3 and the second spiral tube 10. One end of the fifth pipeline 17 is connected to the water tank 2, and the other end is connected to the third pipeline 11 through a three-way valve 12. The second flow meter 18 is installed on the fifth pipeline 17.

[0020] The working principle of the above technical solution is as follows: Close the first valve 5, the second valve 8, and the third valve 15. Adjust the three-way valve 12 to keep the fifth pipe 17 and the third pipe 11 connected. Start the first pump body 13 to transport the purified water in the water tank 2 to the inside of the dilution tank 3 through the fifth pipe 17 and the third pipe 11. The second flow meter 18 records the amount of purified water entering the dilution tank 3. When the appropriate volume of purified water has been transported into the dilution tank 3, adjust the three-way valve 12 to keep the second spiral tube 10 and the third pipe 11 connected. At the same time, open the first valve 5 and keep the second valve 8 closed. At this time, on the one hand, the first pump body 13 can circulate the water inside the dilution tank 3 through the second thin tube 23, the second spiral tube 10, and the third pipe 11. On the other hand, the first pump body 13 can also draw the high-concentration water-reducing agent inside the high-concentration water-reducing agent tank 1 into the first pipe 4 and the first spiral tube 9, and through multiple first thin tubes 21. The high-concentration water-reducing agent mixes with water at different locations inside the second spiral tube 10. During this process, the first flow meter 6 records the amount of high-concentration water-reducing agent. When a suitable volume of high-concentration water-reducing agent is delivered into the dilution tank 3, the first valve 5 is closed and the second valve 8 is opened. At this time, the mixture of high-concentration water-reducing agent and water inside the dilution tank 3 enters the first spiral tube 9 through the second pipe 7, and then enters the second spiral tube 10 through the first thin pipe 21. At the same time, the mixture of high-concentration water-reducing agent and water inside the dilution tank 3 also enters the second spiral tube 10 through the second thin pipe 23, and then returns to the dilution tank 3 through the third pipe 11, thus forming a cycle. The mixture mixes in the first spiral tube 9 and the second spiral tube 10, and also mixes during the process of entering the second spiral tube 10 from the first spiral tube 9. This cycle takes about 30 minutes to achieve the dilution of the high-concentration water-reducing agent, and the dilution is uniform.

[0021] In the above technical solution: This utility model utilizes the cooperation between various structures to allow the high-concentration water-reducing agent to be injected into different positions of the second spiral tube 10 through multiple first thin tubes 21 in the early stage, thereby achieving primary dilution of the high-concentration water-reducing agent; then, the first pump body 13 is used to circulate the mixture of high-concentration water-reducing agent and water in the dilution tank 3, thereby achieving secondary dilution; at the same time, the spiral structure of the first spiral tube 9 and the second spiral tube 10, as well as the curved parts in the entire pipeline, further promote the dilution and mixing of the high-concentration water-reducing agent and water; the overall structure is simplified and the dilution cost is reduced.

[0022] In this embodiment, a first one-way valve 22 is installed on the first capillary tube 21, and a second one-way valve 24 is installed on the second capillary tube 23. The first one-way valve 22 allows the fluid in the first spiral tube 9 to enter the second spiral tube 10 in one direction, and the second one-way valve 24 allows the fluid in the dilution tank 3 to enter the second spiral tube 10 in one direction. Moreover, during the process of the fluid passing through the first one-way valve 22 and the second one-way valve 24, the mixing of the water-reducing agent and water can be promoted, which is beneficial to improving its dilution uniformity and shortening the dilution time.

[0023] The bottom of the dilution tank 3 is connected to a fourth pipe 14, on which a third valve 15 and a second pump body 16 are installed. When it is necessary to discharge the diluted water-reducing agent, the third valve 15 can be opened and the second pump body 16 can be started.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
