[0002] Smelting slag is a solid waste generated during the metallurgical industry, mainly classified into the following categories: iron and steel smelting slag, non-ferrous metal smelting slag, and laterite nickel ore smelting slag. Among them, laterite nickel ore smelting slag is a solid waste generated during the smelting of nickel-iron ore.

[0003] With the growth in global nickel demand, the amount of slag emissions has increased dramatically. The main sources of metallic nickel are the mining and extraction of nickel sulfide ore and laterite nickel ore. Due to its abundant resources and low price, laterite nickel ore has gradually become the main target of nickel mining. Therefore, the amount of slag generated by laterite nickel ore smelting is relatively large.

However, the existing two smelting technologies have low processing capacity for laterite nickel ore smelting waste slag. Therefore, to address the shortcomings of existing technologies, it is necessary to develop a device for producing cementing materials from laterite nickel ore smelting waste slag.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1 As shown, this disclosure discloses an apparatus for producing cementing materials from smelting waste slag, including a twin-shaft mixer 22, a mixing belt conveyor 25, a first camera 38, and a controller 1. The twin-shaft mixer 22 is provided with a feed hopper 21 and a discharge port 24. The waste slag feeding mechanism, the first mixing feeding mechanism, the second mixing feeding mechanism, and the water supply mechanism are all connected to the feed hopper 21. One end of the mixing belt conveyor 25 is placed below the discharge port 24, and the other end extends outward relative to the twin-shaft mixer 22 and then extends upward at an angle. The first camera 38 is installed above the feed hopper 21. The controller 1 has a touch screen display, and the controller 1 is electrically connected to the twin-shaft mixer 22, the waste slag feeding mechanism, the slag belt conveyor 12, the first mixing feeding mechanism, the second mixing feeding mechanism, and the water supply mechanism.

[0027] The first camera 38 captures real-time footage of the material feeding into the feed hopper 21 and transmits the data to the controller in real time. Upon receiving this data, the controller displays it on a touchscreen. By checking the touchscreen, staff can quickly ascertain the feeding status of the waste feeder, the first mixing feeder, the second mixing feeder, and the water supply system to the feed hopper 21.

[0028] The waste slag feeding mechanism includes a first support 2, a rotating shaft 7, and a batching belt conveyor 11. The first support 2 is equipped with a slag silo 5, and a silo discharge valve 51 is installed at the bottom of the slag silo 5. One end of the rotating shaft 7 is placed in the slag silo 5, and a spirally extending stirring blade 8 is installed on this end. The other end passes through the top surface of the slag silo 5 and is connected to a drive motor 6 installed on the top of the slag silo. One end of the batching belt conveyor 11 is placed below the silo discharge valve 51, and the other end extends above one end of the slag belt conveyor 12. The other end of the slag belt conveyor 12 extends to the feed hopper 21.

[0029] The drive motor 6 drives the rotating shaft 7 to rotate, and the rotating shaft 7 drives the stirring blades 8 to rotate. The stirring blades 8 can stir the slag in the slag bin 5, which helps to loosen the slag and prevent the slag from clumping, thus facilitating the discharge of the slag from the slag bin 5.

[0030] Understandably, the hopper discharge valve 51 and the batching belt conveyor 11 work together to obtain the set amount of raw materials.

[0031] To facilitate monitoring of the unloading status of the hopper discharge valve 51, a second camera 4 and a second bracket 3 are added. One end of the second bracket 3 is installed on the first bracket 2, and the other end is used to support the installation of the second camera 4. The second camera 4 corresponds to the interval between the hopper discharge valve 51 and the batching belt conveyor 11.

[0032] The second camera 4 captures the unloading situation of the material unloading valve 51 in the silo and the receiving situation of waste residue by the batching belt conveyor, and transmits the captured image data to the controller in real time. After receiving the image data, the controller displays it on the touch screen.

[0033] It should be noted that the first and second cameras each have corresponding display units on the touch screen, which can prevent staff from confusing the images captured by the first and second cameras.

[0034] In some embodiments of this disclosure, in order to make the shaft rotate stably, a third bracket 10 and a bearing seat 9 are added. The bearing seat 9 is fitted onto the shaft 7. One end of the third bracket 10 is installed in the slag silo 5, and the other end is connected to the bearing seat 9.

[0035] The shaft passes through the bearing housing, and the bearing housing provides support for the shaft, preventing it from wobbling when rotating.

[0036] The third support 10 provides strong support for the bearing housing, allowing it to be stably placed inside the slag silo.

[0037] In some embodiments of this disclosure, a structure of a first mixing and feeding mechanism is provided. The first mixing and feeding mechanism includes a fourth support 13, a first frame 19, and a first screw feeder 18. A cement cylinder silo 14 is mounted on the top of the fourth support 13. The top of the cement cylinder silo 14 is provided with a first hopper 15 in the form of an inverted conical cylinder. The bottom of the first hopper 15 is provided with a first discharge pipe 16, and a first discharge valve 17 is installed on the first discharge pipe 16. The first frame 19 is mounted on the fourth support 13. The first screw feeder 18 is mounted on the first frame 19 and has a first inlet 181 and a first discharge port 182. The first inlet 181 is connected to the first discharge valve 17.

[0038] Cement cylinder silo 14 can be used to store cement.

[0039] Cement unloading operation:

[0040] The first discharge valve 17 is opened by the controller 1. The cement in the cement cylinder silo 14 falls into the first feed port 181 through the first discharge pipe 16 and the first discharge valve 17. The cement then falls into the first screw batching machine 18 through the first feed port 181. The first screw batching machine 18 batches and conveys the cement according to the set cement ratio weight. The first screw batching machine 18 discharges the cement into the feed hopper 21 through the first discharge port 182.

[0041] When cement is no longer needed to be discharged, the first discharge valve can be closed via the controller, and the cement cylinder silo will stop discharging cement.

[0042] In some embodiments of this disclosure, a structure of a second mixing and feeding mechanism is provided. The second mixing and feeding mechanism includes a seventh support 28, a second frame 29, a second spiral feeder 30, and a guide chute 35. A bentonite cylindrical silo 34 is mounted on the top of the seventh support 28. A second hopper 33 with an inverted conical structure is located at the bottom of the bentonite cylindrical silo 34. A second discharge pipe 32 is located at the bottom of the second hopper 33, and a second discharge valve 31 is installed on the second discharge pipe 32. The second frame 29 is mounted on the seventh support 28. The second spiral feeder 30 is mounted on the second frame 29. The second spiral feeder 30 has a second inlet 301 and a second discharge outlet 302. The second inlet 301 is connected to the second discharge valve 31. One end of the guide chute 35 is positioned below the second discharge outlet 302, and the other end extends towards the inlet hopper 21.

[0043] The bentonite cylindrical silo 34 can be used to store bentonite powder.

[0044] Work style:

[0045] The second discharge valve 31 is opened, and the bentonite powder in the bentonite cylindrical silo 34 falls into the second feed inlet 301 through the second discharge pipe 32. The bentonite powder falls into the second screw feeder 30 through the second feed inlet 301. The second screw feeder 30 feeds and conveys the bentonite powder according to the set bentonite powder ratio and weight. The second screw feeder discharges the bentonite powder through the second discharge port 302. The bentonite powder falls into the guide trough 35, and the guide trough 35 guides the bentonite powder into the feed hopper 21.

[0046] When it is not necessary to discharge bentonite powder from the bentonite cylinder silo 34, the second discharge valve can be closed by controlling the controller, which will prevent the bentonite cylinder silo 34 from discharging bentonite powder downwards.

[0047] In some embodiments of this disclosure, a water supply mechanism is provided, comprising a support platform 20, a water delivery pipe 45, a second water valve 46, a flow meter 47, and a water conveyance pipe 39. The support platform 20 is equipped with a water pump 44 and a water tank 42. One end of the water pump 44 is connected to the water tank 42, and the top of the water tank 42 has a feed inlet 41. One end of the water delivery pipe 45 is connected to the other end of the water pump 44, and the other end extends to the feed hopper 21. The second water valve 46 and the flow meter 47 are installed at intervals on the water delivery pipe 45. The water conveyance pipe 39 is connected to the water tank 42 and is equipped with a first water valve 40.

[0048] The feed port 41 is used to add an admixture to the water tank 42. Polyaluminum chloride can be used as the admixture.

[0049] Work style:

[0050] Open the first water valve 40, and water is supplied to the water tank 42 through the water pipe 39. Then, add the admixture into the water tank through the feed port 41. After stirring, start the water pump 44, open the second water valve 46, and the water pump 44 draws the admixture solution from the water tank and sends it into the water supply pipe 45. The admixture solution in the water supply pipe 45 passes through the second water valve 46 and the flow meter 47 in sequence and enters the feed hopper 21. The flow meter 47 monitors the flow rate in the water supply pipe in real time and transmits the monitored flow data in real time. The controller 1 analyzes and processes the flow data transmitted by the flow meter and displays it on the touch screen. When the cumulative flow of the admixture solution measured by the flow meter reaches the set required amount of admixture solution, the controller controls the water pump to stop working, closes the second water valve 46, and the water supply pipe stops supplying water.

[0051] In some embodiments of this disclosure, a support structure for the water delivery pipe is provided, in which a pipe bracket 48 is added. The water delivery pipe 45 is connected to the first mixing and feeding mechanism via at least one pipe bracket 48.

[0052] Specifically, such as Figure 1 ,2 As shown, the number of pipe supports installed between the water supply pipe 45 and the fourth support 13 in the first mixing and feeding mechanism can be 1, 2, 3 or 4, etc.

[0053] Pipe support 48 supports water delivery pipe 45, so that water delivery pipe extends stably towards feed hopper 21.

[0054] In some embodiments of this disclosure, a mounting structure for the first camera is provided, which includes the addition of a ninth bracket 37. One end of the ninth bracket 37 is connected to the seventh bracket 28, and the other end is used to support the mounting of the first camera 38.

[0055] The ninth bracket 37 supports the first camera 38 suspended above the feed hopper 21, which facilitates the first camera to record the feeding status of the waste slag feeding mechanism, the first mixing feeding mechanism, the second mixing feeding mechanism and the water supply mechanism.

[0056] In some embodiments of this disclosure, a sixth support 26 and a collection bin 27 are added to collect the produced binder. The collection bin 27 is mounted on the sixth support 26 and connected to the mixed material belt conveyor 25.

[0057] The twin-shaft mixer discharges the resulting cementitious material to the mixed material belt conveyor, which then discharges the cementitious material into the collection bin, which can temporarily collect the cementitious material.

[0058] It should be noted that the batching belt conveyor, belt conveyor, screw batching machine, and twin-shaft mixer are all existing, commonly used, and technologically mature equipment. They can be installed according to work requirements.

[0059] It should also be noted that, for the purpose of unified control of all components in this utility model, a control system is included, which has a display screen. The control system is electrically connected to the three-compartment batching belt conveyor 1, the slag belt conveyor 12, the first discharge valve 19, the second discharge valve 21, the first spiral batching belt conveyor 5, the second spiral batching belt conveyor 7, the twin-shaft mixer 13, the mixed material belt conveyor 14, the flow meter 12, and the water pump 10. The control valve 102 and the batching belt conveyor 2 are electrically connected to the control system. The required raw material quantity can be set on the control system, and the batching belt conveyor 2 and the control valve 102 will correspondingly measure the set raw material quantity. The required aqueous solution supply quantity can also be set on the control system, and the flow meter monitors the flow rate of the aqueous solution conveyed by the conveying pipe 30 in real time and transmits the data to the control system. The control system accumulates and analyzes the data, and when the conveyed aqueous solution reaches the set quantity, the control system can control the water pump to stop working.

[0060] The working principle of this utility model is as follows:

[0061] Raw materials (such as smelting slag from laterite nickel ore, clay, etc.) are loaded into slag silo 5. According to process requirements, the required raw materials are evenly unloaded onto slag belt conveyor 12 via batching belt conveyor 11, and then sent to twin-shaft mixer 13 via slag belt conveyor 12. Cement and bentonite powders, etc., are batched according to process requirements. Cement in cement cylinder silo 14 is conveyed to twin-shaft mixer via first screw batching machine 18. Bentonite powder in bentonite cylinder silo 34 is conveyed to twin-shaft mixer via second screw batching machine 30. Water feeding mechanism required for batching is also conveyed to twin-shaft mixer.

[0062] Specifically, the process involves opening the first water valve 40 to add water to the water tank 42 to the required amount, then closing the first water valve 40. A certain amount of additive is then added to the water tank 42. After thorough stirring and dissolution, the water pump 44 is started, and the second water valve 46 is opened. The water pump 44 delivers the additive solution to the twin-shaft mixer 22 through the water delivery pipe 45. The flow meter 47 on the water delivery pipe 45 monitors the liquid flow rate in real time. After the additive solution is thoroughly mixed with the raw materials, cement, bentonite, and other ingredients, the twin-shaft mixer 22 unloads the mixture onto the mixing belt conveyor 25. The mixing belt conveyor 25 then transports the mixture to the collection bin 27. The collection bin 27 facilitates the unloading of the mixture onto mechanical transfer equipment, which then transports the mixture to the construction site. This method achieves the recycling and utilization of laterite nickel ore smelting waste slag, and since the construction site has a large demand for the mixture, it allows for the significant recycling and utilization of laterite nickel ore smelting waste slag.

[0063] Cement is the cementing material for plastic concrete, enabling it to form a binder with good physical properties. It also acts as a curing agent for heavy metal ions; the hydrated calcium silicate gel in cement can adsorb and solidify heavy metal ions. Bentonite is an expanding agent in the cementing material. When bentonite is cemented, it expands upon contact with water, blocking the internal pores and capillaries of the cementing material, resulting in a lower permeability coefficient and improved seepage prevention performance. Simultaneously, the layered aluminosilicate structure of bentonite-montmorillonite can also adsorb heavy metal ions and organic toxins upon contact with water, and after cementing and solidification with the cementitious material, these heavy metal ions and organic toxins become insoluble in water. Polyaluminum chloride (PAC) admixture is a novel inorganic polymer water purification agent that can adsorb heavy metal ions and organic toxins, such as Cr⁶⁺, that are difficult for cementitious materials and bentonite to adsorb. After its flocs adsorb heavy metal ions and organic toxins, they solidify with cementitious materials and become insoluble in water. Adding PAC or ferrous sulfate to the ingredients enhances and stabilizes the solidification of heavy metal ions and other toxins. HMC-M1, a heavy metal chelating agent, is a highly efficient heavy metal chelating agent that can form insoluble chelate precipitates with various heavy metal ions (copper, nickel, lead, zinc, cadmium, etc.) over a wide pH range, thereby enhancing the solidification / stabilization of heavy metals. Sodium carboxymethyl cellulose, sodium polyacrylate, and other gelling agents can both adsorb heavy metal ions and increase the viscosity of plastic concrete, which is beneficial for the compaction of plastic concrete during construction.

[0064] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
