Description

Technical Field

[0001] The invention relates to the technical field of concrete preparation, and in particular to a concrete preparation device for optimizing steel slag aggregate performance based on laser micro-holes and magnetic position control. Background Art

[0002] With the rapid development of the construction industry, the demand for construction aggregates continues to rise, and the mining of natural aggregate resources (such as sand and gravel) in many areas has reached its limit. In view of the large industrial cities (such as Baotou, etc.), the output of steel slag aggregate is large, the accumulation occupies land and is highly polluting, and the degree of engineering application and resource utilization is low.

[0003] As a new type of environmentally friendly building material, steel slag concrete uses steel slag produced during steel production as aggregate to replace traditional natural aggregate. Although steel slag concrete has a certain waste disposal capacity and reflects environmental protection characteristics, its inherent physical and chemical characteristics lead to certain deficiencies in engineering applications. The details are as follows:

[0004] (1) The steel slag aggregate sinks and is unevenly distributed, resulting in reduced concrete strength:

[0005] Uneven aggregate distribution leads to concrete paste-aggregate stratification and uneven density, which weakens the bond strength between cement paste and aggregate, thereby reducing the overall strength of concrete. Especially when the particle size, shape and difference of steel slag are large, it will lead to excessive sparseness, hollowing, leakage of slurry in some parts, and eventually component failure. In addition, the physical and chemical properties of steel slag are different from those of natural aggregates. Aggregates sink and are unevenly distributed, resulting in poor corrosion resistance and frost resistance of steel slag concrete. Changes in the particle morphology and density of steel slag may also lead to uneven expansion or contraction of concrete, increase thermal expansion stress, and ultimately lead to structural cracks.

[0006] (2) Free calcium oxide and magnesium oxide lead to poor stability of steel slag aggregate and are difficult to remove, which restricts the engineering application of steel slag aggregate.

[0007] Due to the high density and heavy weight of steel slag aggregate, it is difficult to solve the problem of poor volume stability of steel slag aggregate. Steel slag often contains a large amount of free calcium oxide (CaO) and magnesium oxide (MgO). These substances generate calcium hydroxide and magnesium hydroxide in water, and the volume expands by about 2 times, but the reaction process is extremely slow, which can easily cause uneven volume changes in the concrete that has been solidified, and is an important unstable factor in concrete. The free calcium oxide and magnesium oxide in steel slag have unique surface characteristics. Their structure is usually dense, and the surface is often covered with a layer of molten material, which makes their aging process slow. This chronic hydration reaction is not only difficult to control, but also quite difficult to handle. As the hydration reaction proceeds, it is accompanied by significant volume expansion. If this volume change is not effectively managed and controlled, it will cause serious damage to the internal structure of the concrete, and eventually lead to cracks, spalling or structural degradation of the concrete. To this end, we have introduced a concrete preparation device based on laser micropores and magnetic position control to optimize the performance of steel slag aggregate. Summary of the invention

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) Laser micro-holes improve the aggregate surface: Through the continuous conveying of the first conveyor belt, the steel slag aggregate can be stably delivered to the laser scanning area. By setting the first conveyor belt to stop intermittently, the steel slag aggregate is in a stationary state during laser drilling to ensure the depth and uniformity of the holes. The steel slag aggregate is blown by high-pressure air to achieve the turning of the steel slag aggregate. This process ensures that each side of the steel slag aggregate can be evenly drilled, and can also promote the cleaning of the steel slag aggregate surface to avoid the residue and debris generated during the laser processing from affecting the subsequent process. Uniform laser drilling not only improves the surface properties of the steel slag aggregate, but also improves its bonding strength with the cement slurry, and effectively alleviates the expansion problem that may be caused by the steel slag.

[0023] (2) Magnetic positioning control to optimize aggregate distribution: By adjusting the magnitude and direction of the DC current of the first magnetic matrix electromagnet and the second magnetic matrix electromagnet, different magnetic forces can be applied to the steel slag aggregate. The steel slag aggregate containing magnetic material is suspended in a suitable position in the steel slag concrete by using bidirectional (up and down) magnetic guidance to avoid sinking and aggregation of the steel slag aggregate. By adjusting the magnetic field strength of the upper and lower electromagnets (i.e., the first magnetic matrix electromagnet and the second magnetic matrix electromagnet), the magnetic matrix can be precisely controlled to adjust the distribution pattern of the steel slag aggregate in the steel slag concrete, optimize the uniformity of the steel slag aggregate in the mixing process of the steel slag concrete, and thus improve the performance of the steel slag concrete.

[0024] (3) Iron powder adhesion realizes weak magnetic compensation for steel slag aggregate with weak magnetism: iron powder is mixed with liquid to form iron powder slurry, and then steel slag aggregate is added to it, and the iron powder slurry is evenly wrapped on the surface of steel slag aggregate. The steel slag aggregate coated with iron powder needs to be dried to make it more firmly attached to the surface of steel slag aggregate, and the excess iron powder slurry is screened. After the iron powder coating, drying and screening are completed, the steel slag aggregate is sent to the magnetic field for homogenization.

[0025] (4) Air pressure transient and vortex air hole cleaning: During the cleaning process of steel slag aggregate after laser drilling, the piston is used to pressurize the steel slag aggregate under the support of the vortex airflow inside the equipment to achieve instantaneous conversion of high and low air pressure, so as to effectively remove the powder attached to the microporous surface; the piston pushes the pressurization, and then generates an instantaneous negative pressure effect through rapid pressure relief, which quickly absorbs the dust and fine particles generated by laser drilling, thereby achieving the purpose of cleaning the microporous surface of the steel slag aggregate and cleaning the hole.

[0026] (5) Programmable digital multi-module cooperative control mechanism: According to the specific needs of the sample, the central control module can define multiple module operating parameters; relying on the track material system (i.e., circulation module), the auxiliary modules can be increased or decreased according to specific needs, reflecting the platform concept; some modules are modular components, and the number of modules can be adjusted according to actual needs. In addition, data analysis can be performed to optimize the uniform dispersion of steel slag aggregate under magnetic control, thereby improving the performance and quality stability of the sample.
