[0046] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0047] Although the present application can be easily presented as embodiments of different forms, only some of the specific embodiments are shown in the drawings and described in detail in this specification. It should be understood that this description should be regarded as an exemplary description of the principles of the present application and is not intended to limit the present application to that described herein.

[0048] Thus, a feature indicated in this specification will be used to illustrate one of the features of an embodiment of the application, rather than implying that each embodiment of the application must have the described features. In addition, it should be noted that this specification describes many features. Although some features can be combined together to illustrate possible system designs, these features can also be used for other combinations that are not explicitly described. Thus, unless otherwise stated, the described combinations are not intended to be limiting.

[0049] In the embodiments shown in the drawings, the indications of directions (such as up, down, left, right, front and back) used to explain the structure and movement of various elements of the present application are not absolute but relative. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the description of the positions of these elements changes, the indications of these directions also change accordingly.

[0050] Normally, the concrete masterbatch or concrete powder masterbatch produced by the factory cannot be directly used in the concrete mixing plant. It 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, the state of the concrete material (sand, cement, gravel, fly ash, etc.) may change, and the on-site ambient temperature may also change. Therefore, the formula of the compound admixture needs to be adjusted with the above changes, making the formula of the compound admixture change and adjust frequently.

[0051] At present, the production of concrete admixture compounding adopts automated compounding production control. According to the appropriate concrete admixture formula that technicians try out in the ready-mixed concrete enterprise, compounding production is carried out. Concrete admixtures are used in stages in the ready-mixed concrete production enterprise. The use time of each batch of finished products may be 1 day or several days. If the raw materials or the construction site environment change significantly, the current compound admixture cannot adapt, and technicians need to go to the ready-mixed concrete production enterprise to test mix concrete. As a result, technicians spend a lot of time on the way to the ready-mixed concrete enterprise and in the concrete test mix, and they cannot respond quickly and timely when the factors affecting the performance of concrete change.

[0052] Therefore, compounding admixtures at the construction site can meet the needs of timely adjusting the single production formula for compounding production according to the construction materials and site environment. However, compounding admixtures at the construction site has the following problems:

[0053] (1) During the compounding process, a stirring paddle is usually used for on-site mixing, which makes it easier to produce a mixing dead corner in the compounding tank, resulting in uneven mixing and long mixing time, which leads to low efficiency of admixture compounding and poor admixture quality.

[0054] (2) The compounding equipment used on-site by concrete production enterprises requires manual input of formulas based on the production environment. Manual calculation and input are cumbersome and prone to errors, resulting in low efficiency of admixture compounding and poor admixture quality.

[0055] (3) The admixture formed after the formula is adjusted and the admixture after the formula is adjusted are injected into a storage tank, which affects the quality of the admixture.

[0056] Part or all of the above technical problems can be optimized through the limited embodiments described below in this application.

[0057] Please refer to Figure 1 , Figure 1 1 is a schematic diagram of the structure of an admixture compounding device provided in an embodiment of the present application, and the admixture compounding device may include: a feed component 11, a first liquid level metering component 12, a compounding component 13, a storage component 14, a second liquid level metering component 15, and a control component 16. The discharge end of the feed component 11 may be connected to the feed end of the compounding component 13, the feed component 11 is used to transfer a preset amount of material to the compounding component 13, and the first liquid level metering component 12 is installed in the feed component 11.

[0058] The compounding component 13 is used to mix materials. The compounding component 13 may include a compounding tank 131 and a blowing component 132. The air outlet end of the blowing component 132 is located in the compounding tank 131, and the material outlet end of the compounding tank 131 is connected to the material feed end of the storage component 14. The blowing component 132 can blow air into the containing cavity of the compounding tank 131 to generate convection circulation in the containing cavity of the compounding tank 131, thereby stirring the material in the compounding tank 131. In this way, the blowing component 132 blows and stirs the material in the compounding tank 131, so that the material can be stirred more fully and the mixed material can be more uniform. In addition, compared with the use of a stirring paddle to stir the material in the related art, the stirring time of the blowing stirring is short, and the amount of material that can be stirred at one time is large, which can improve the production efficiency and the quality of the compounded product.

[0059] The storage assembly 14 can be used to store the mixed materials, and the second liquid level metering assembly 15 is installed in the storage assembly 14. Among them, the feed 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 to the control assembly 16. The control assembly 16 can store various types of admixture formulas in advance, and the various types of admixture formulas can be customized for different types of admixture formulas for multiple application scenarios of concrete enterprises, as well as different strength grades, different transportation distances, different raw materials, different climate temperature changes and other needs. The feed 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 all be connected to the control assembly 16 by wire or wirelessly, so as to realize that the compounding process of the admixture can be remotely controlled by the control assembly 16.

[0060] Exemplarily, during the use of the admixture compounding device, when the second liquid level metering component 15 detects that the remaining amount of finished admixture material in the storage component 14 is less than or equal to a first preset value, the control component can obtain the target admixture formula used this time from the pre-stored multiple types of admixture formulas, and start the feeding component 11 to quantitatively convey the material to the compounding tank 131 according to the target admixture formula. At the same time, start the blowing component 132 to blow and stir the material in the compounding tank 131. During this process, the remaining amount of material in the feeding component 11 can be monitored in real time by the first liquid level metering component 12. After the material in the compounding tank 131 is evenly stirred to form the finished admixture material, the finished admixture material of the admixture is transferred to the storage component 14. When the second liquid level metering component 15 detects that the amount of finished admixture material in the storage component 14 is less than or equal to the second preset value, the conveying of the finished admixture material to the storage component 14 can be stopped. The second preset value may be greater than the first preset value. The second preset value may be the highest preset liquid level in the finished product tank 141 , and the first preset value may be the lowest preset liquid level in the finished product tank 141 .

[0061] In this way, the material amount in the feeding component 11 is monitored in real time by the first liquid level metering component 12, and the storage component 14 is monitored in real time by the second liquid level metering component 15. When the finished additive material in the storage component 14 is insufficient, the feeding component 11 and the compounding component 13 can be started by the control component 16 for automatic production, thereby improving production efficiency.

[0062] In summary, the embodiment of the present application provides an additive compounding device including a feeding component 11, a first liquid level metering component 12, a compounding component 13, a storage component 14, a second liquid level metering component 15 and a control component 16. The second liquid level metering component 15 monitors the amount of finished additive material in the storage component 14 in real time. When the amount of finished additive material remaining in the storage component 14 is less than or equal to a predetermined value, the control component can start the feeding component 11 and the compounding component 13 for compounding production according to one of the multiple types of pre-stored additive formulas, and monitors the amount of material in the feeding component 11 in real time through the first liquid level metering component 12, so that the amount of each material can be more accurate, and the quality of the compounded additive can be improved. In addition, the compounding component 13 uses the blowing component 132 to blow and stir the material in the compounding tank 131, which can reduce the stirring time, and the amount of material that can be stirred at one time is large, which can improve production efficiency and further improve the quality of the compounded additive.

[0063] Please refer to Figure 1 In an optional embodiment, the storage component 14 may include multiple finished product tanks 141, the second liquid level metering component 15 may include multiple second liquid level metering units 151, and the multiple second liquid level metering units may be electrically connected to the control component 16; the multiple second liquid level metering units 151 may be installed in the multiple finished product tanks 141 in a one-to-one correspondence; the feed ends of the multiple finished product tanks 141 may be connected to the discharge end of the compounding tank 131, and the multiple finished product tanks 141 may be used to store different types of additive finished materials, respectively, and the additive finished materials are mixed materials.

[0064] When the production environment or concrete materials change, different admixture formulas need to be replaced to adapt to the current production environment and concrete materials. Therefore, the admixture compounding device in the embodiment of the present application can generate a variety of admixture finished materials. If the formula of the admixture finished material produced this time is significantly different from the formula of the admixture finished material produced last time, and the admixture finished materials produced twice are collected in the same finished product tank 141, the admixture finished material produced this time is mixed with the residual material of the admixture finished material produced last time, which may affect the quality of the admixture finished material produced this time. In this way, different types of admixture finished materials can be packaged in different finished product tanks 141 to avoid the impact between different types of admixture finished materials.

[0065] In an optional implementation, the staff can customize different types of admixture formulas according to the needs of multiple application scenarios of concrete enterprises, as well as different strength grades, different transportation distances, different raw materials, different climate temperature changes, etc., and enter them into the formula library of the application (APP). The control component 16 may include a controller and a display. The staff can log in to the application through the display and view various types of admixture formulas from the application. Alternatively, various types of admixture formulas can be directly stored in the control component 16. Exemplarily, various types of admixture formulas can also be automatically generated by the control component 16 according to usage requirements, and this embodiment of the present application is not limited to this.

[0066] In an exemplary embodiment, each type of admixture formula corresponds to each finished product tank 141, that is, multiple types of admixture formulas correspond one-to-one to multiple finished product tanks 141. When n types of admixture formulas are stored in the control component 16, the storage component 14 may include n finished product tanks 141, where n is an integer greater than or equal to 1. Exemplarily, three types of admixture formulas are stored in the control component 16: A1, A2, and A3, and the storage component 14 may include three finished product tanks 141: B1, B2, and B3. 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. In this way, the influence between different types of admixture finished materials can be avoided.

[0067] In an exemplary embodiment, multiple groups of admixture formulas are pre-stored in the control component 16, each group of admixture formulas corresponds to each finished product tank 141, multiple groups of admixture formulas correspond to multiple finished product tanks 141 one-to-one, any group of admixture formulas includes multiple admixture formulas, and the concentration difference of the admixture finished material corresponding to the multiple admixture formulas in any group of admixture formulas is less than or equal to 30%. When n types of admixture formulas are stored in the control component 16, the storage component 14 may include m finished product tanks 141, n is greater than or equal to m, and n and m are both integers greater than or equal to 1. Exemplarily, the control component 16 stores six types of admixture formulas: A1, A2, A3, A4, A5 and A6, and the storage component 14 may include three finished product tanks 141: B1, B2 and B3, wherein the concentrations of the admixture finished materials formed by A1, A2, A3, A4, A5 and A6 are 20%, 30%, 40%, 50%, 70% and 90% respectively, the admixture finished materials formed according to A1 and A2 can be stored in B1, the admixture finished materials formed according to A3 and A4 can be stored in B2, and the admixture finished materials formed according to A5 and A6 can be stored in B3, so that the influence between different types of admixture finished materials with large differences can be avoided.

[0068] Alternatively, multiple admixture formulas may be grouped according to their components, for example, the overlap of the components of multiple admixture formulas in any group of admixture formulas is greater than or equal to 80%, that is, admixture finished materials with relatively similar components may be stored in the same finished product tank.

[0069] Please refer to Figure 1 In an optional embodiment, the storage component 14 may also include a discharge pipe 145, a discharge valve 146 and a discharge pump 147, the feed end of the discharge pipe 145 is connected to the discharge end of the compounding tank 131, the discharge valve 146 and the discharge pump 147 are installed on the discharge pipe 145, and the discharge valve 146 and the discharge pump 147 are both electrically connected to the control component 16.

[0070] The storage assembly 14 may further include a plurality of inlet pipes 142 and a plurality of inlet valves 143, one end of each of the plurality of inlet pipes 142 is connected to the discharge end of the discharge pipe 145, and the other end is connected to the plurality of finished product tanks 141 in a one-to-one correspondence, and the plurality of inlet valves 143 are installed in a one-to-one correspondence on the plurality of inlet pipes 142, and the plurality of inlet valves 143 are electrically connected to the control assembly 16. Exemplarily, the storage assembly 14 may include two inlet pipes 142 and two inlet valves 143.

[0071] The discharge valve 146 and the inlet valve 143 may both include one or more control valves such as electric valves, hydraulic valves, pneumatic valves, turbine valves, electromagnetic valves, electromagnetic hydraulic valves, electro-hydraulic valves, gas-hydraulic valves, spur gear-driven valves, bevel gear-driven valves, etc. Exemplarily, the discharge valve 146 and the inlet valve 143 are solenoid valves or air-controlled ball valves.

[0072] Please refer to Figure 1 In an optional embodiment, the storage assembly 14 may further include a plurality of float switches 144, which are mounted one by one on the tops of the plurality of finished product tanks 141 and are electrically connected to the control assembly 16. The float switch 144 may be used to control the opening or closing of the inlet valve 143 on the inlet pipe 142 connected to the finished product tank 141, so as to prevent the liquid in the finished product tank 141 from being overfilled, thereby controlling the liquid level in the finished product tank 141 within a preset range.

[0073] Please refer to Figure 1 In an optional embodiment, the blowing assembly 132 may include an air supply unit 1321, a gas pipeline 1322 and an air pipe diverter 1323; the air pipe diverter 1323 is located in the compounding tank 131, and has multiple air outlets on the air pipe diverter 1323; the air supply unit 1321 is located outside the compounding tank 131, and is connected to the air pipe diverter 1323 through the gas pipeline 1322.

[0075] The shape and size of the air pipe diverter 1323 can be adaptively designed according to the shape and size of the compounding tank 131 , with avoiding a stirring dead corner in the compounding tank 131 as the design principle.

[0076] When the feeding component 11 injects the material into the compounding tank 131, air can be supplied to the air pipe diverter 1323 through the air supply unit 1321, and the air is discharged from the air pipe diverter 1323 and flows upward. The rising air drives the nearby liquid to generate upward momentum. When the air is discharged from the liquid, the liquid naturally sinks due to gravity. In this way, a convection effect can be formed in the compounding tank 131 to mix the materials in the compounding tank 131 evenly.

[0077] Please refer to Figure 1In an optional embodiment, the feed component 11 may include multiple feed tanks 113, and the first liquid level metering component 12 includes multiple first liquid level metering units 121; the multiple first liquid level metering units 121 are installed in the multiple feed tanks 113 in a one-to-one correspondence; the discharge ends of the multiple feed tanks 113 are all connected to the feed end of the compounding tank 131, and the multiple feed tanks 113 are respectively used to store different types of materials.

The multiple feed pipes 111 can correspond one-to-one to the multiple feed tanks 113. One end of any feed pipe 111 is connected to the discharge end of the corresponding feed tank 113. The other ends of the multiple feed pipes 111 can all be connected to the feed port of the compounding tank 131. Multiple feed valves are installed one-to-one on the multiple feed pipes 111.

The weighing unit 136 can be used to measure the material in the compounding tank 131. The weighing unit 136 can include 4 sensors, and the rated weighing capacity of each sensor is greater than or equal to 50 kilograms. The multiple first liquid level meter units and the weighing unit 136 are all electrically connected to the control component 16.

This can make the amount of each material used more accurate, improve the quality of the compounded admixture, and improve the reliability of the admixture compounding device.

[0083] The feed pump 112 and the discharge pump 147 in the embodiment of the present application can both adopt pumps with intelligent flow functions, which can improve the accuracy of the feed amount and the discharge amount.

[0085] Step 201: The control component 16 obtains a target admixture formula from multiple types of admixture formulas.

[0086] In an exemplary embodiment, the control component 16 can be integrated into a control system, which can include a PLC control system or a DCS control system. The control system can also include an industrial Internet of Things touch screen (HMI) to facilitate operators to set programs through the industrial Internet of Things touch screen and control the entire compounding process such as valve opening, liquid level monitoring, and pump opening or closing.

[0087] In an optional embodiment, the admixture compounding device may further include an alarm unit, which is electrically connected to the control component 16 and is used to sound an alarm. The alarm unit may include at least one of a sound alarm component, a photoelectric alarm component, and a remote alarm component; the sound alarm component and the photoelectric alarm component are located outside the box; the remote alarm component may be located in a monitoring room, or the remote alarm component may be integrated in a user's terminal (such as a mobile phone, a laptop computer, etc.).

[0088] When at least one of the first liquid level unit, the second liquid level unit and the weighing unit 136 detects an abnormal situation (such as the liquid level in the finished product tank 141 is higher than the maximum liquid level), the control component can support WeChat alarm, SMS alarm and telephone alarm functions, and can also support third-party software, APP, mini-programs and other applications; the APP or mini-program includes application management such as formula management, tank configuration and production consumption statistics. The operator remotely controls and adjusts the production formula through the APP or mini-program system; through the APP or mini-program system, the operator can remotely and quickly adjust the compound production formula according to changes in customer application scenarios.

[0089] In an exemplary embodiment, the operator can select a corresponding target admixture formula from the APP formula library according to the actual needs of the concrete enterprise, and click to confirm. The admixture formula corresponds to a finished product tank 141 for storing finished materials.

[0090] In an optional embodiment, the admixture compounding device may further include a temperature measuring unit and a humidity measuring unit, and various production data in the current production environment may be obtained through the temperature measuring unit and the humidity measuring unit. A relationship table between production data and admixture formula may be pre-stored in the control component 16, and the control component 16 may select a target admixture formula according to the detected production data. Alternatively, the production data may also be input into the control component 16 by an operator, and the production data may also include data such as concrete type and concrete humidity.

[0091] Step 202 , the control component 16 controls the opening of the feed component 11 according to the target additive formula, and injects preset amounts of multiple materials into the compounding tank 131 through the feed component 11 .

[0092] The feed pumps 112 corresponding to multiple feed tanks 113 can be started one by one through the control component 16. According to the selected target additive formula, a set amount of water-reducing mother liquor, collapse-preserving mother liquor, water or additives can be extracted from the feed tank 113 and transported to the compounding tank 131 through the feed pipe 111. When the weighing sensor under the compounding tank 131 detects that the weight of the material in the compounding tank 131 reaches the set weight, the control component can control the feed component 11 to stop feeding.

[0093] Step 203 : The control component 16 receives the first detection signal sent by the first liquid level metering component 12 to monitor the amount of material injected into the compounding tank 131 according to the first detection signal.

[0094] The amount of material in the feed tank 113 of the feed component 11 can be monitored in real time by the first liquid level metering component 12 to obtain the amount of material injected into the compounding tank 131 .

[0095] Step 204 , the control component 16 turns on the blowing component 132 to mix the various materials in the compounding tank 131 .

[0096] While conveying materials to the compounding tank 131 , the control section 16 can control the execution of various material mixing steps in the compounding tank 131 , and the blowing component 132 in the compounding tank 131 can blow and homogenize the liquid in the compounding tank 131 .

[0097] Step 205: When the amount of material injected into the compounding tank 131 reaches a preset amount, the feed assembly 11 is closed.

[0098] The dual control method of controlling the feed amount by the first liquid level metering component 12 and verifying the feed amount by the weighing unit 136 makes the amount of each material more accurate, improves the quality of the compounded admixture, and improves the reliability of the admixture compounding device.

[0099] Step 206: After the preset mixing time has passed, the control component 16 controls the blowing component 132 to close, and obtains the finished additive material.

[0100] The preset homogenization time can be adjusted according to the admixture formula and the adaptability of the production environment. For example, the preset homogenization time can range from 10 minutes to 100 minutes.

[0101] Step 207 , the control component 16 opens the storage component 14 , and injects the finished additive material from the compounding tank 131 into the storage component 14 .

[0102] In an optional embodiment, the storage component 14 may include multiple finished product tanks 141, the second liquid level metering component 15 includes multiple second liquid level metering units 151, the multiple second liquid level metering units 151 are installed in the multiple finished product tanks 141 one by one, the multiple second liquid level meter units are all electrically connected to the control component 16, multiple types of additive formulas correspond one by one to the multiple finished product tanks 141, and the feed ends of the multiple finished product tanks 141 are all connected to the discharge end of the compounding tank 131.

[0103] When the various materials in the compounding tank 131 are evenly mixed, the discharge valve 146 and the discharge pump 147 on the discharge pipe 145 connected to the discharge port of the compounding tank 131 are opened, and the inlet valve 143 on the inlet pipe 142 connected to the finished product tank 141 corresponding to the target additive formula is opened, and at the same time, the inlet valve 143 on the inlet pipe 142 connected to other finished product tanks 141 is closed, so that the evenly mixed additive finished material can be extracted into the corresponding finished product tank 141 through the discharge pump 147.

[0104] Step 208 : The control component 16 receives the second detection signal sent by the second liquid level metering component 15 to monitor the amount of finished material injected into the storage component 14 according to the second detection signal.

[0105] The amount of the finished additive material in the storage component 14 is obtained through the second liquid level metering component 15 .

[0106] Step 209: When the amount of finished material injected into the storage component 14 reaches the target amount, the control component 16 closes the storage component 14 to stop receiving the finished material of the additive.

[0107] The target quantity can be the demand for finished admixture materials pre-set by the operator based on the current construction situation.

[0108] In an exemplary embodiment, the control component 16 can receive the liquid level monitoring signal sent by the second liquid level metering unit, and can obtain the liquid level in the finished product tank 141 corresponding to the target admixture formula in real time through the second liquid level metering unit 151; and enable the finished product tank 141 to receive the admixture finished material output by the compounding tank 131, until the liquid level in the finished product tank 141 is higher than or equal to the highest preset liquid level, close the discharge valve 146 and the discharge pump 147 in the storage component 14 and the inlet valve 143 on the inlet pipe 142 connected to the finished product tank 141, and stop receiving the admixture finished material.

[0109] Optionally, when the liquid level in the finished product tank 141 is lower than or equal to the minimum preset liquid level, the control component issues a production instruction, and injects preset amounts of multiple materials into the compounding tank 131 through the feeding component 11 according to the target additive formula, and repeats the above steps 201 to 209, thereby realizing unattended automatic production.

[0110] In the embodiment of the present application, the admixture compounding device can control the whole process of the admixture compounding production process by controlling the component components, and realize automatic production and stopping by identifying the liquid level change of the finished product storage tank, without the need for personnel on duty, so that the admixture compounding production process is fully intelligent, which can save the labor input cost of compounding production. In addition, it can also realize small-batch compounding production of admixtures according to the production volume of concrete production enterprises, and can ensure the quality of admixture products.

[0111] Please refer to Figure 3 , Figure 3 It is a flow chart of another admixture compounding method provided by an embodiment of the present application. The operator can remotely control the opening of the admixture compounding device and confirm whether to switch the current admixture formula according to factors such as the on-site environment. If the current on-site environment changes greatly, the operator remotely selects the admixture formula from the formula library at the control terminal and determines the corresponding finished product tank 141. The control component 16 determines whether the liquid level of the corresponding finished product tank 141 is lower than the lowest preset liquid level. If it is lower than the lowest liquid level, the feed component 11 is opened, the material of the feed tank 113 is extracted and transported to the compounding tank 131. At the same time, the weighing unit 136 weighs the material in the compounding tank 131, and the compounding tank 131 homogenizes multiple materials. After the homogenization is completed, the admixture finished material is extracted to the finished product tank 141, and the production is automatically stopped when the finished product liquid level is higher than the highest preset liquid level. The finished admixture material is extracted from the finished product tank 141 to the concrete tank 20, and the liquid level in the finished product tank 141 decreases. The control component 16 determines whether the liquid level in the finished product tank 141 is lower than the minimum preset liquid level and starts automatic production.

[0112] In summary, the embodiment of the present application provides an admixture compounding method, which can select the admixture formula that best suits the current production environment from the various types of admixture formulas pre-stored in the control component 16 according to factors such as the raw material state, ambient temperature and ambient humidity at the construction site, and produce admixture finished materials according to the admixture formula, which can improve the adaptability of the produced admixture finished materials to the current production environment, thereby improving the quality of the admixture. The amount of finished additives in the storage component 14 can also be monitored in real time through the second liquid level metering component 15. When the amount of finished additives remaining in the storage component 14 is less than or equal to a predetermined value, the control component can start the feeding component 11 and the compounding component 13 for compounding production according to one of the multiple types of pre-stored additive formulas, and monitor the feeding amount in real time through the first liquid level metering component 12 and the weighing unit 136, so that the amount of each material can be more accurate and the quality of the compounded additive can be improved. In addition, the compounding component 13 uses the blowing component 132 to blow and stir the material in the compounding tank 131, which can reduce the stirring time, and the amount of material that can be stirred at one time is larger, which can improve production efficiency and further improve the quality of the compounded additive.
