Description

Technical Field

[0001] This utility model relates to the technical field of concrete admixture mixing equipment, specifically to a concrete admixture liquid mother liquor dilution and mixing equipment. Background Technology

[0002] Concrete admixtures are substances added to improve and adjust the properties of concrete. The application of concrete admixtures in engineering is receiving increasing attention, as their addition plays a role in improving concrete performance. During production, the mother liquor needs to be diluted and mixed with other raw materials to ensure the quality of the admixture.

[0003] Existing mother liquor dilution and mixing equipment lacks an effective filtration device at the bottom of the mother liquor tank, resulting in ineffective filtration of the mother liquor during dilution and mixing, which affects the mixing quality of the additives. In addition, the existing mixing equipment only uses the unidirectional rotation of the stirring blades to drive the liquid in the mixing tank to rotate and mix in one direction, resulting in a generally poor mixing effect between the additives and the mother liquor, which also affects the mixing quality of the mother liquor. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a dilution and mixing device for concrete admixture liquid mother liquor. By setting up a mother liquor tank and a filter screen, when the mother liquor in the tank enters the mixing tank, the impurities in the mother liquor are filtered out by the filter screen, ensuring the quality of the mother liquor and thus ensuring the mixing quality of the admixture. This can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concrete admixture liquid mother liquor dilution and mixing device, comprising a mixing tank, a tank cover on the upper side of the mixing tank, a stirring motor at the center of the upper side of the tank cover, a return pipe connected to the upper outer side of the mixing tank, the return pipe being tangent to the inner side of the mixing tank, a No. 3 valve connected to the return pipe, a mother liquor tank at the lower side of the return pipe, a filter screen at the center of the bottom side of the mother liquor tank, a stirring shaft connected to the output end of the stirring motor, a stirring blade connected to the lower end of the stirring shaft, and a return hole provided at the contact position between the inner side wall of the mixing tank and the return pipe.

[0006] Furthermore, a second valve is provided below the third valve, a pump is connected to the lower end of the return pipe, and a drain pipe is connected to one side of the lower end of the return pipe.

[0007] Furthermore, an electromagnetic flow valve is installed on the lower side of the mother liquor tank, and a liquid level sensor is installed inside the mother liquor tank.

[0008] Furthermore, a liquid extraction pipe is connected to the lower part of the electromagnetic flow valve, and a valve No. 1 is provided at the end of the liquid extraction pipe near the mixing tank.

[0009] Furthermore, a base is provided at the lower part of the mixing tank, and the base is fixedly connected to the mixing tank.

[0010] Furthermore, the extraction pipe is connected to the center of the lower side of the mixing tank via a flange, and the extraction pipe is also connected to the first valve via a flange.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model, through the setting of a mother liquor tank and a filter screen, ensures that when the mother liquor from the mother liquor tank enters the mixing tank, impurities in the mother liquor are filtered out by the filter screen, thus ensuring the quality of the mother liquor and, consequently, the mixing quality of the additives.

[0013] This invention, through the design of a reflux pipe, mixing tank, stirring shaft, and stirring blades, ensures that the rotation direction of the stirring blades is opposite to the liquid flow direction in the reflux pipe, and that the flow direction of the mother liquor flowing out of the reflux pipe is opposite to the rotation direction of the liquid in the mixing tank. This allows the mixed mother liquor and the liquid in the mixing tank to be fully mixed, ensuring the mixing quality of the additives. Attached Figure Description

[0019] 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.

[0020] Please see Figure 1-4 This embodiment provides a technical solution: a concrete admixture liquid mother liquor dilution and mixing equipment, including a mixing tank 1, a tank cover 3 on the upper side of the mixing tank 1, a stirring motor 2 at the center of the upper side of the tank cover 3, a return pipe 10 connected to the upper outer side of the mixing tank 1, the return pipe 10 being tangent to the inner side of the mixing tank 1, a third valve 9 connected to the return pipe 10, a mother liquor tank 7 at the lower side of the return pipe 10, a filter screen 17 at the center of the bottom side of the mother liquor tank 7, a stirring shaft 12 connected to the output end of the stirring motor 2, a stirring blade 13 connected to the lower end of the stirring shaft 12, and a return hole 14 provided at the contact position between the inner side wall of the mixing tank 1 and the return pipe 10.

[0021] like Figure 1-4 As shown, during the production of concrete admixture liquid, the mother liquor is added to the mother liquor tank 7, and water is added to the mixing tank 1. The stirring motor 2 drives the stirring shaft 12 and the stirring blade 13 to rotate and stir the diluted mother liquor. The pump 6 draws the liquid out of the mixing tank 1 through the liquid extraction pipe 5, and after passing through the second valve 8, it flows back into the mother liquor tank 7. The mixed liquid is mixed with the mother liquor again and flows back into the liquid extraction pipe 5. Finally, it flows into the mixing tank 1 through the return pipe 10. The direction of the liquid flowing out of the return pipe 10 is opposite to the direction of the rotating liquid in the mixing tank 1. This makes the direction of the diluted mother liquor flowing out of the return pipe 10 opposite to the direction of the liquid flowing in the mixing tank 1, so that the diluted mother liquor and the liquid in the mixing tank 1 are fully mixed, ensuring the mixing quality.

[0022] Valve 8 is located below valve 9. Pump 6 is connected to the lower end of return pipe 10. Drain pipe 16 is connected to one side of the lower end of return pipe 10.

[0023] An electromagnetic flow valve 11 is installed on the lower side of the mother liquor tank 7, and a liquid level sensor 15 is installed inside the mother liquor tank 7.

[0024] The lower part of the electromagnetic flow valve 11 is connected to the liquid extraction pipe 5, and a valve 18 is installed at the end of the liquid extraction pipe 5 near the mixing tank 1.

[0025] A base 4 is provided at the bottom of the mixing tank 1, and the base 4 is fixedly connected to the mixing tank 1.

[0026] The extraction pipe 5 is connected to the center of the lower side of the mixing tank 1 via a flange, and the extraction pipe 5 is connected to valve 18 via a flange.

[0027] The working principle of the concrete admixture liquid mother liquor dilution and mixing equipment provided by this utility model is as follows: Figures 1-4 As shown, during the production of concrete admixture liquid, the mother liquor is added to the mother liquor tank 7, and water is added to the mixing tank 1. The stirring motor 2 drives the stirring shaft 12 and the stirring blade 13 to rotate and stir the diluted mother liquor. The pump 6 draws the liquid out of the mixing tank 1 through the liquid extraction pipe 5, and after passing through the second valve 8, it flows back into the mother liquor tank 7. The mixed liquid is mixed with the mother liquor again and flows back into the liquid extraction pipe 5. Finally, it flows into the mixing tank 1 through the return pipe 10. The direction of the liquid flowing out of the return pipe 10 is opposite to the direction of the rotating liquid in the mixing tank 1. This makes the direction of the diluted mother liquor flowing out of the return pipe 10 opposite to the direction of the liquid flowing in the mixing tank 1, so that the diluted mother liquor and the liquid in the mixing tank 1 are fully mixed, ensuring the mixing quality.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
