[0039] In order to make the purpose, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0040] Although the present application can be easily embodied as different forms of embodiments, only some specific embodiments are shown in the drawings and described in detail in the present specification, and it can be understood that the present specification should be regarded as a demonstrative description of the principles of the present application, and is not intended to limit the present application to what is described herein.

[0041] Thus, one feature that is described in the specification can be used to explain one embodiment of the application, but not necessarily every embodiment of the application. Moreover, it should be noted that the specification describes many features. Although certain features can be combined in one embodiment, these features can also be used in other embodiments that do not explicitly mention the combination. Thus, unless otherwise noted, the combination of features is not intended to limit the application.

[0042] In the embodiments shown in the drawings, the indications of direction, such as up, down, left, right, front and back, are used to explain the structure and movement of various elements of the application and are not absolute but relative. These indications are appropriate when the elements are in the position shown in the drawings. If the position of the elements changes, the indications of direction also change accordingly.

[0043] Generally, the concrete mother liquor or concrete powder material produced by the factory cannot be directly used in the concrete mixing station, and needs to be compounded (for example, adding water, retarder, air entraining agent, etc.) to meet the use requirements of concrete in different situations. In the actual construction process, due to the possible changes in the state of the materials of the concrete (sand, cement, gravel, fly ash, etc.) and the possible changes in the site environment temperature, the formula of the compounded admixture needs to be adjusted according to the changes, so that the formula of the compounded admixture needs to be adjusted frequently.

[0044] At present, the production of concrete admixture is compounded by automatic production control. The appropriate concrete admixture formula is compounded by technicians in a commercial concrete enterprise. The concrete admixture is used in commercial concrete production enterprises in stages. The use time of each batch of product may be 1 day or several days. If the raw materials or the construction site environment change greatly, the current compounded admixture cannot adapt, and technicians need to go to the commercial concrete production enterprise to compound the concrete. This results in that the technicians spend a lot of time on the road to the commercial concrete enterprise and on the concrete compounding, and when the factors affecting the performance of the concrete change, it is also impossible to respond quickly and timely.

[0045] Therefore, compounding the admixture at the construction site can meet the demand for adjusting the single production formula for compounding production according to the construction materials and the site environment in a timely manner. However, there are the following problems in compounding the admixture at the construction site:

[0046] (1) In the compounding process, a stirring tank is usually used for on-site stirring, so that it is easy to produce a stirring dead angle in the compounding tank, resulting in the problems of uneven stirring and long stirring time, thereby reducing the work efficiency of the admixture compounding and the quality of the admixture.

[0047] (2) The compounding device used on site by the concrete production enterprise needs manual input of formula according to the production environment, manual calculation and input are more complicated and prone to errors, resulting in low work efficiency of admixture compounding and poor quality of admixture.

[0048] (3) The admixture formed after adjusting the formula and the admixture after adjusting the formula are both injected into one storage tank, which affects the quality of the admixture.

[0049] The above part and all technical problems can be optimized by the limited embodiments of the utility model.

[0050] Please refer to Figure 1 , Figure 1 is a structural schematic view of an admixture compounding device provided by the embodiments of the utility model, which can include: a feeding assembly 11, a first liquid level metering assembly 12, a compounding assembly 13, a storage assembly 14, a second liquid level metering assembly 15 and a control assembly 16. The discharge end of the feeding assembly 11 can be in communication with the feeding end of the compounding assembly 13, the feeding assembly 11 is used to transmit a preset amount of material into the compounding assembly 13, and the first liquid level metering assembly 12 is installed in the feeding assembly 11.

[0051] The compounding assembly 13 is used to mix materials, and the compounding assembly 13 can include a compounding tank 131 and a blowing assembly 132, the gas outlet end of the blowing assembly 132 is located in the compounding tank 131, and the discharge end of the compounding tank 131 is in communication with the feeding end of the storage assembly 14. The blowing assembly 132 can blow gas into the containing cavity of the compounding tank 131 to generate convection circulation in the containing cavity of the compounding tank 131, so as to stir the material in the compounding tank 131. In this way, the material in the compounding tank 131 is stirred by the blowing assembly 132, which can make the material stirring more sufficient, and the mixed material more uniform. In addition, compared with the use of stirring paddles to stir the material in the related art, the blowing stirring has a short stirring time, and a large amount of material can be stirred at a time, which can improve the production efficiency and also improve the quality of the compounded product.

[0052] The storage assembly 14 can be used to store the mixed material, and the second liquid level metering assembly 15 is installed in the storage assembly 14. The feeding assembly 11, the first liquid level metering assembly 12, the blowing assembly 132, the second liquid level metering assembly 15, and the storage assembly 14 are all electrically connected with the control assembly 16. A plurality of types of admixture formulas can be pre-stored in the control assembly 16, which can be different types of admixture formulas customized for the needs of multiple application scenarios of a concrete enterprise, different strength grades, different transportation distances, different raw materials, and different climate temperature difference changes. The feeding assembly 11, the first liquid level metering assembly 12, the blowing assembly 132, the second liquid level metering assembly 15, and the storage assembly 14 can be wired or wirelessly connected with the control assembly 16, so that the compounding process of the admixture can be remotely controlled by the control assembly 16.

[0053] For example, during the use of the admixture compounding device, when the second liquid level metering assembly 15 detects that the remaining admixture product in the storage assembly 14 is less than or equal to a first preset value, the control assembly can obtain a target admixture formula for this use from the plurality of types of admixture formulas pre-stored, and start the feeding assembly 11 to quantitatively deliver the material to the compounding tank 131 according to the target admixture formula, and at the same time, start the blowing assembly 132 to blow and stir the material in the compounding tank 131. During this process, the first liquid level metering assembly 12 can be used to monitor the remaining amount of material in the feeding assembly 11 in real time. After the material in the compounding tank 131 is uniformly stirred to form the admixture product, the admixture product is transferred to the storage assembly 14. When the second liquid level metering assembly 15 detects that the amount of admixture product in the storage assembly 14 is less than or equal to a second preset value, the delivery of the admixture product to the storage assembly 14 can be stopped. The second preset value can be greater than the first preset value, and the second preset value can be the highest preset liquid level in the product tank 141, and the first preset value can be the lowest preset liquid level in the product tank 141.

[0054] In this way, by monitoring the amount of material in the feeding assembly 11 in real time through the first liquid level metering assembly 12 and monitoring the storage assembly 14 in real time through the second liquid level metering assembly 15, when the amount of admixture product in the storage assembly 14 is insufficient, the feeding assembly 11 and the compounding assembly 13 can be automatically started by the control assembly 16 for production, which can improve the production efficiency.

[0055] In conclusion, the utility model embodiment provides an external agent compounding device which comprises a feeding assembly 11, a first liquid level metering assembly 12, a compounding assembly 13, a storage assembly 14, a second liquid level metering assembly 15 and a control assembly 16, the second liquid level metering assembly 15 is used for monitoring the amount of external agent finished product in the storage assembly 14 in real time, when the amount of external agent finished product remaining in the storage assembly 14 is less than or equal to a predetermined value, the control assembly can start the feeding assembly 11 and the compounding assembly 13 to produce according to one of the pre-stored multiple types of external agent formula, and the first liquid level metering assembly 12 is used for monitoring the amount of material in the feeding assembly 11 in real time, so that the use amount of each material is more accurate, the quality of the compounded external agent can be improved, and the compounding assembly 13 blows and stirs the material in the compounding tank 131 through the blowing assembly 132, so that the stirring time can be reduced, the amount of material that can be stirred at a time is larger, the production efficiency can be improved, and the quality of the compounded external agent can be further improved.

[0057] Since different external agent formulas need to be replaced to adapt to the current production environment and concrete material when the production environment or concrete material changes, the external agent compounding device in the utility model embodiment can generate multiple external agent finished products, if the formula of the external agent finished product produced this time is quite different from the formula of the external agent finished product produced last time, and the external agent finished products produced this time and last time are collected in the same finished product tank 141, the residual material of the external agent finished product produced this time and the external agent finished product produced last time mixed together may affect the quality of the external agent finished product produced this time, so that different types of external agent finished product can be packed in different finished product tanks 141 to avoid affecting different types of external agent finished product.

[0058] In an alternative embodiment, the staff can customize different types of admixture formulations for the concrete enterprise multi-application scenarios, different strength grades, different transportation distances, different raw materials, different climate temperature difference changes, and the like, and input the admixture formulations into the formulation library of the application program (APP). The control assembly 16 can include a controller and a display. The staff can log in to the application program through the display and view the various types of admixture formulations from the application program, or the various types of admixture formulations can be directly stored in the control assembly 16. For example, the various types of admixture formulations can also be automatically generated by the control assembly 16 according to the use requirements, and the embodiments of the present application do not limit this.

[0059] In an exemplary embodiment, each type of admixture formulation corresponds to each finished tank 141, that is, the various types of admixture formulations correspond one-to-one to the plurality of finished tanks 141. When the control assembly 16 stores n types of admixture formulations, the storage assembly 14 can include n finished tanks 141, where n is an integer greater than or equal to 1.

The admixture finished material formed according to A1 can be stored in B1, the admixture finished material formed according to A2 can be stored in B2, and the admixture finished material formed according to A3 can be stored in B3.

When the control component 16 stores n types of admixture formulations, the storage component 14 can include m product tanks 141, n being greater than or equal to m, and n and m each being an integer greater than or equal to 1. For example, the control component 16 stores 6 types of admixture formulations: A1, A2, A3, A4, A5, and A6, and the storage component 14 includes 3 product tanks 141: B1, B2, and B3, wherein the admixture product materials formed by A1, A2, A3, A4, A5, and A6 have concentrations of 20%, 30%, 40%, 50%, 70%, and 90%, respectively, the admixture product materials formed by A1 and A2 can be stored in B1, the admixture product materials formed by A3 and A4 can be stored in B2, and the admixture product materials formed by A5 and A6 can be stored in B3, so that the influence between different types of admixture product materials with a large difference can be avoided.

For example, the storage component 14 can include two storage pipelines 142 and two storage valves 143.

[0069] When the feeding assembly 11 injects material into the compounding tank 131, the gas supply unit 1321 can supply gas to the gas pipe shunt 1323. The air discharged from the gas pipe shunt 1323 flows upward, and the rising air drives the nearby liquid to move upward.
