Description

Technical Field

[0001] This utility model relates to the field of concrete production equipment, and in particular to a quantitative dispensing device for high-performance concrete admixtures. Background Technology

[0002] In the concrete production industry, high-performance concrete admixtures play a crucial role, significantly improving concrete performance. Consequently, admixture dispensing devices have become essential equipment for ensuring production quality. Currently, while commercially available admixture dispensing devices can perform basic dispensing functions, many problems still exist.

[0003] In existing technologies, the residue of admixtures on the inner walls of dosing pipes and containers is a significant problem. Due to the viscosity of the admixtures, some adheres to the inner walls of the pipes and containers during dosing. This not only wastes materials and increases production costs but also severely impacts subsequent dosing operations.

[0004] Residual admixtures can cause discrepancies between the actual amount added in the next batch and the set value, resulting in inaccurate actual admixture dosage in concrete and affecting its performance stability. Furthermore, residual admixtures can contaminate subsequent batches, leading to inconsistent concrete quality across different batches. Therefore, it is essential to develop a high-performance concrete-specific admixture quantitative dosing device that can effectively avoid admixture residue. Utility Model Content

[0005] The main objective of this invention is to provide a high-performance concrete admixture quantitative dispensing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A high-performance concrete admixture quantitative dispensing device includes a concrete silo. An admixture dispensing chamber is connected above the concrete silo. The admixture dispensing chamber includes an outer shell and a dispensing component, a weighing component, and a rinsing component disposed inside the outer shell. The dispensing component includes an admixture storage tank, a first connecting pipe, a weighing chamber, and a second connecting pipe connected in sequence. An admixture storage tank is located on one side of the top of the inner cavity of the outer shell, a support plate is located at the bottom of the inner cavity of the outer shell, and a weighing chamber is located above the support plate. The inner cavity of the weighing chamber is conical, and the weighing component is installed at the bottom of the weighing chamber. The rinsing component includes a clean water tank and a rinsing pipeline. A clean water tank is located on one side of the top of the inner cavity of the outer shell, and the bottom of the clean water tank is connected to the rinsing pipeline, which is connected to the weighing chamber. A control panel is located on one side of the outer shell.

[0008] Furthermore, a first liquid pump and a first solenoid valve are installed on the first connecting pipe, and a second solenoid valve is installed on the second connecting pipe. The lower end of the second connecting pipe is connected to the concrete sump. The first liquid pump, the first solenoid valve, and the second solenoid valve are all electrically connected to the control panel.

[0009] Furthermore, the flushing pipeline includes a third connecting pipe, an annular pipe, and a spray pipe connected in sequence. The upper end of the third connecting pipe is connected to the clean water tank, and the lower end of the third connecting pipe is connected to the annular pipe. The lower end of the annular pipe is connected to multiple spray pipes, and the lower end of the spray pipes is connected to the upper part of the conical inner cavity of the weighing chamber.

[0010] Furthermore, a second liquid pump is installed on the third connecting pipe, and a third solenoid valve is installed on the spray pipe. Both the second liquid pump and the third solenoid valve are electrically connected to the control panel.

[0011] Furthermore, the weighing component is an electronic weighing device, and two electronic weighing devices are symmetrically arranged. The electronic weighing devices are electrically connected to the control panel.

[0012] Furthermore, sliders are provided on the left and right sides of the weighing chamber, and the inner wall of the outer shell is provided with a sliding groove that is connected to the sliders for sliding up and down.

[0013] This invention also includes other components that enable the high-performance concrete admixture quantitative dispensing device to function properly. These devices or components all employ conventional techniques in the art. Furthermore, devices and components not specifically defined in this invention all employ conventional techniques in the art, such as the electronic weighing device and the first liquid pump mentioned in this application. In specific implementation, appropriate equipment or component models can be selected according to the specific working scenario.

[0014] The working principle of this invention is as follows: When adding admixtures, the control panel activates the first liquid pump and the first solenoid valve, allowing the material in the admixture storage tank to be precisely injected into the weighing chamber through the first connecting pipe. Symmetrically arranged electronic weighers monitor weight data in real time and feed it back to the control panel. When the preset value is reached, the first liquid pump and the first solenoid valve are automatically shut off, and then the second solenoid valve is opened, allowing the material in the weighing chamber to be introduced into the concrete silo through the second connecting pipe. After addition is completed, the control panel activates the second liquid pump and the third solenoid valve. The flushing water from the clean water tank is diverted to multiple spray pipes through the third connecting pipe and the annular pipe, effectively removing residual admixtures from the silo wall through multi-directional flushing at the upper part of the conical inner cavity. The weighing chamber maintains vertical stability during material transfer through the sliding cooperation of the sliders on both sides and the outer shell grooves, avoiding weighing errors.

[0015] Compared with the prior art, the present invention has the following beneficial effects: effectively removes residual additives from the bin wall: through multi-directional spray rinsing, the inner wall of the weighing bin is automatically cleaned, reducing waste and batch contamination caused by material residue.
