The following describes various embodiments of the present invention in detail in conjunction with the drawings.

[0033] Example 1

[0034] See also Figures 1 to 9The present invention preferably provides a technical solution: a device for preparing unburned bricks from waste incineration slag, including a slag pretreatment device and an unburned brick preparation device: wherein the slag pretreatment device includes: a support 1; a liquid storage frame 6 for vibrating and cleaning the slag arranged on the support 1; and a transmission assembly 3, on which a feed box assembly 4 is arranged; and further including a stepped screening magnetic suction assembly 5 arranged between the liquid storage frame 6 and the feed box assembly 4, for screening the slag transported by the feed box assembly 4; the transmission assembly 3 is arranged on the support 1 and connected to the stepped magnetic suction assembly 5. The step-type screening magnetic suction component 5 is connected, which is used to drive the step-type screening magnetic suction component 5 to move in an irregular wave trajectory, so as to operate the feed box component 4, the step-type screening magnetic suction component 5 and the liquid storage frame 6 together, and obtain the pretreated slag; the unburned brick preparation device includes: a mobile stirring frame component 8 arranged on one side of the support 1; a preparation module arranged close to one side of the mobile stirring frame component 8; and also includes a water injection component arranged on one side of the support 1, and the mobile stirring frame component 8, the preparation module, and the water injection component are used to cooperate in the preparation of unburned bricks.

[0035] This application consists of two parts: a slag pretreatment device and an unburned brick preparation device, to achieve the slag pretreatment and unburned brick preparation process;

[0036] It is known that the five most abundant elements in slag are Ca, O, C, Si, and Fe, and it is mainly composed of phases such as CaCO3 and SiO2, and also includes metal oxides such as Al2O3, Fe2O3 and MgO. The composition of slag is similar to that of natural aggregate, and it can be used as a raw material for building materials. However, the maximum chloride ion content of annual structural concrete does not exceed the regulation of 0.6g / kg, while the maximum average chloride ion content in slag is 8 times the standard limit. At the same time, the content of heavy metals such as Cd, Cr, Cu and Zn in all slag samples exceeds the soil pollution risk screening value of GB15618-2018 "Soil Environmental Quality Standard Agricultural Land Soil Pollution Risk Control Standard (Trial)", and there is a certain risk of heavy metal pollution. The heavy metal content seriously exceeds the standard and cannot be used directly. Therefore, before using slag as building materials, it is necessary to pretreat the slag to reduce the risk of environmental pollution;

[0037] Slag sampling: Sample 150kg of slag, separate the unburned combustibles and metal blocks, and mix the remaining slag evenly. Take a sample of more than 1kg and seal it to prevent moisture from volatilizing;

[0038] Pretreatment step: the feed box assembly 4, the stepped screening magnetic suction assembly 5 and the liquid storage frame 6 provided in the present application are sequentially distributed from top to bottom. When the transmission assembly 3 is running, on the one hand, it realizes the connection and disconnection between the stepped screening magnetic suction assembly 5 and the feed box assembly 4 to realize the falling of the slag, and on the other hand, it drives the stepped screening magnetic suction assembly 5 to perform irregular horizontal and vertical movements. This process can realize the screening of the slag size and the removal of impurities, wherein the impurities are specifically magnetic substances such as iron, and the stepped screening magnetic suction assembly 5 can The iron and remaining impurities are removed by its own magnetic properties, and the slag particle size distribution is adjusted by its own sieve holes, so that all particle sizes are less than 8 mm and gathered at the bottom of the stepped screening magnetic suction component 5. At this time, through the structural characteristics of the transmission component 3, the bottom of the stepped screening magnetic suction component 5 can be extended into the liquid storage frame 6 and washed. The liquid in the liquid storage frame 6 is preferably deionized water, and the screened slag is washed multiple times to remove soluble salts, and naturally dried to obtain pre-treated slag;

[0039] Brick making steps: use slag, river sand, cement, lime and gypsum as basic aggregates, select sodium silicate as activator, add the materials into the mobile mixing frame assembly 8 in proportion, add sufficient water and mix them to make slurry, then pour the slurry into the preparation module under the mobile mixing frame assembly 8, and then carry out natural curing. The specific operation steps are as follows: curing under normal temperature and pressure (natural curing); watering once every 4 to 6 hours in the initial stage of curing; watering once every 10 hours after 10 days of curing; watering once a day after 15 days of curing until the end of the 28-day curing period.

[0040] This application not only reduces the risk of environmental pollution by pretreating the slag, but also reduces the leaching concentration of heavy metals and achieves a certain solidification and stabilization effect. In addition, the selected slag and river sand have a more uniform particle size distribution, which is more conducive to the stable and safe chemical reaction and enhances the compressive strength.

Figure 5 The horizontal part of the first wave band is used for the opening and closing of the outlet slot of the step-type screening magnetic suction component 5 and the feed box component 4, while the wave part of the first wave band is used for the screening and impurity removal of the slag. As can be seen from the figure, the waveform of the second wave band is smaller in range and higher in frequency than that of the first wave band, so as to facilitate the vibration cleaning of the slag;

[0044] Therefore, when the first slider 302 runs horizontally inside the first guide rail 301, the stepped screening magnetic suction assembly 5 can run in an irregular wave trajectory. This process not only realizes the screening and magnetic separation process of the stepped screening magnetic suction assembly 5, but also the stepped screening magnetic suction assembly 5 moves forward and downward and extends into the liquid storage frame 6 to carry out the slag cleaning and desalination process. Its backward and upward movement can realize its connection with the feed box assembly 4, that is, realize the opening of the feed box assembly 4, so that it can feed the material to the stepped screening magnetic suction assembly 5.

[0046] As other embodiments of the present invention, the feed box assembly 4 includes two support plates 401 arranged on two first guide rails 301, and a box body 402 fixed on the opposite surfaces of the tops of the two support plates 401, wherein two relatively running crushing rollers 403 are arranged in the box body 402, and an outlet groove is opened at the bottom; and a driving box 404 is arranged on the side wall of the box body 402, and the output end of the driving motor arranged in the driving box 404 extends into the interior of the box body 402 and is fixed to one of the crushing rollers 403; it also includes driving teeth fixed on the output shaft of the driving motor; a transmission rod fixed at one end of the other crushing roller 403 close to the driving box 404 extends into the interior of the driving box 404 and is fixed with transmission teeth, and the transmission teeth are meshed with the driving teeth.

[0047] Combination Figure 1 , 2 As shown, in this embodiment, the two crushing rollers 403 realize the relative movement of the two crushing rollers 403 through the driving force of the driving motor and the meshing characteristics of the transmission teeth and driving teeth. Figure 6 In this state, the left crushing roller 403 rotates clockwise and the right crushing roller 403 rotates counterclockwise, thereby realizing the crushing process of the slag.
