Description

Technical Field

[0001] This utility model relates to the field of molten slag recycling technology, and in particular to a high-efficiency molten slag recycling and treatment device. Background Technology

[0002] Molten slag refers to liquid waste generated during high-temperature smelting, combustion, or chemical reactions. It typically has high temperature, complex chemical composition, and special physical properties, and requires cooling treatment before further resource utilization or safe disposal.

[0003] Currently, traditional molten slag recycling and processing equipment usually requires cooling the high-temperature molten slag first, and then crushing it for secondary use. This method has shortcomings: when the high-temperature molten slag is cooled by water, dust or vapor containing heavy metals such as lead (Pb) and cadmium (Cd) will be generated. If these waste gases are discharged directly without treatment, they will not only pollute the air, but also pose a serious threat to the health of workshop personnel. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a high-efficiency molten slag recovery and treatment device, which aims to improve the existing technology's inability to timely treat the waste gas generated during the cooling process of molten slag, as well as the problem of easy clogging of filter holes during the cooling water filtration process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency molten slag recycling and treatment device includes a base, a plurality of cylinders fixedly connected to the top of the base, a support plate fixedly connected to the output end of two adjacent cylinders, an L-shaped plate installed on the top of each of the two support plates, a mesh frame fixedly connected between the two L-shaped plates, a cooling pool fixedly connected to the top of the base, a purification component and a filter component provided on the top of the base.

[0007] The purification component includes a housing, the bottom of which is fixedly connected to the top of the base. Two connecting pipes are fixedly connected to the outside of the housing, and multiple suction heads are fixedly connected to the ends of the two connecting pipes away from the housing. An exhaust fan is installed on the inner wall of the housing, and a filter plate is slidably connected inside the housing. Multiple activated carbons are placed inside the filter plate.

[0008] As a further description of the above technical solution:

[0009] The filter assembly includes a cylindrical body, with multiple support pillars fixedly connected to the bottom of the cylindrical body. Each of the multiple support pillars is fixedly connected to the top of the base. A motor is fixedly connected to the top of the cylindrical body, and a turntable is fixedly connected to the output end of the motor. A cylinder is fixedly connected to the side of the turntable away from the motor. A frame is fitted around the outer periphery of the cylinder. A connecting rod is fixedly connected to the bottom of the frame. Multiple scrapers are fixedly connected to the outer periphery of the connecting rod. A fixing ring is fixedly connected inside the cylindrical body, and a filter cylinder is fixedly connected to the inner side of the fixing ring. A drain pipe is fixedly connected to the bottom of the filter cylinder.

[0010] As a further description of the above technical solution:

[0011] A fixing plate is fixedly connected to the outside of the cooling pool, and a blower is installed on the top of the fixing plate;

[0012] As a further description of the above technical solution:

[0013] A drain pipe is fixedly connected to the outside of the cooling pool, and the end of the drain pipe away from the cooling pool is fixedly connected to the outer wall of the cylinder.

[0014] As a further description of the above technical solution:

[0020] As a further description of the above technical solution:

[0021] A handle is fixedly connected to the top of the filter plate.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the air inside the box is discharged by starting the exhaust fan, and then a suction force is formed at the suction head to draw the exhaust gas generated by cooling into the connecting pipe and send it into the box; the exhaust gas will first pass through the filter plate, and the harmful substances can be removed by the adsorption function of the activated carbon inside. The clean gas after adsorption treatment is finally discharged from the box, thereby significantly reducing the pollution risk of exhaust gas emissions to the environment, achieving a highly efficient and environmentally friendly exhaust gas treatment effect, and reducing the harm of exhaust gas to the human body.

[0024] 2. In this utility model, the turntable is driven to rotate by starting the motor, which in turn drives the cylinder to rotate. The frame moves together with the cylinder. At this time, the connecting rod moves up and down under the drive of the frame, which in turn causes the scraper to move up and down synchronously in the filter cylinder. This keeps the impurities in the filter cylinder in a suspended and flowing state, thereby avoiding the accumulation of impurities and clogging of the filter holes, and ensuring the efficient and stable operation of the filtration operation. The impurities separated by filtration fall into the drain pipe under the action of gravity. The impurities can be easily collected by simply opening the drain pipe port, which significantly improves the convenience and practicality of the recycling process. Attached Figure Description

[0033] 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.

[0034] Reference Figure 1 , Figure 2 and Figure 6 This utility model provides an embodiment of a high-efficiency molten slag recycling and treatment device, including a base 1. Multiple cylinders 2 are fixedly connected to the top of the base 1. Support plates 5 are fixedly connected to the output ends of two adjacent cylinders 2. The cylinders 2 are driven by a controller, so that their output ends drive the support plates 5 to move up and down. L-shaped plates 6 are installed on the top of the two support plates 5. A mesh frame 7 is fixedly connected between the two L-shaped plates 6. A cooling pool 8 is fixedly connected to the top of the base 1. The L-shaped plates 6 are driven by the support plates 5, which in turn drive the mesh frame 7 to move up and down, so that the high-temperature molten slag is cooled in the cooling pool 8. A purification component is provided on the top of the base 1 to purify the waste gas generated during cooling. A filter component is provided on the top of the base 1 to filter impurities in the cooling water.

[0035] The purification assembly includes a housing 11, the bottom of which is fixedly connected to the top of a base 1, which provides support for the housing 11. Two connecting pipes 10 are fixedly connected to the outside of the housing 11, and multiple suction heads 9 are fixedly connected to the ends of the two connecting pipes 10 away from the housing 11. An exhaust fan 16 is installed on the inner wall of the housing 11. When the high-temperature molten slag is water-cooled, exhaust gas is generated. At this time, the exhaust fan 16 is activated to exhaust the air inside the housing 11, causing exhaust gas to be generated near the suction heads 9. The negative pressure zone draws the exhaust gas into the connecting pipe 10 and then discharges it into the housing 11. A filter plate 27 is slidably connected inside the housing 11, and multiple activated carbons 28 are placed inside the filter plate 27. When the exhaust gas enters the housing 11, it passes through the filter plate 27, and then the activated carbon 28 adsorbs the harmful substances in the exhaust gas before discharging it into the air, thus avoiding environmental pollution caused by direct exhaust gas discharge. Furthermore, the filter plate 27 is slidably connected inside the housing 11, making it easy to replace.

[0036] Reference Figures 1-5The filter assembly includes a cylinder 12, with multiple support pillars 15 fixedly connected to the bottom of the cylinder 12. These support pillars 15 are all fixedly connected to the top of the base 1, supporting the cylinder 12. A motor 13 is fixedly connected to the top of the cylinder 12, and a turntable 19 is fixedly connected to the output end of the motor 13. A cylinder 20 is fixedly connected to the side of the turntable 19 away from the motor 13. A frame 22 is fitted around the outer periphery of the cylinder 20, and a connecting rod 21 is fixedly connected to the bottom of the frame 22. Multiple scrapers 23 are fixedly connected to the outer periphery of the connecting rod 21. A fixing ring 26 is fixedly connected inside the cylinder 12, and a filter cylinder 25 is fixedly connected to the inner side of the fixing ring 26. When cooling water enters the housing 11, it falls onto the fixing ring 26. The impurities then flow into the filter cartridge 25 for filtration. A drain pipe 24 is fixedly connected to the bottom of the filter cartridge 25. The motor 13 is started by the controller, and the motor 13 converts electrical energy into mechanical energy. Therefore, its output end will drive the turntable 19 and the cylinder 20 to rotate together. After the cylinder 20 rotates, it will drive the frame 22 to move together. The frame 22 will drive the connecting rod 21 to move up and down, thereby driving the scraper 23 on the outer periphery of the connecting rod 21 to move up and down together. Through the continuous rotation of the turntable 19, the scraper 23 is indirectly driven to move up and down reciprocatingly, so that the impurities inside the filter cartridge 25 are always in a suspended and flowing state, avoiding the impurities from clogging the filter holes and thus affecting the filtration rate.

[0037] Reference Figure 1 A fixed plate 3 is fixedly connected to the outside of the cooling pool 8. A blower 4 is installed on the top of the fixed plate 3. The fixed plate 3 is used to support the blower 4. When the molten slag is cooled and lifted, the blower 4 is started to achieve the effect of rapid air drying.

[0038] Reference Figure 2 and Figure 3 A drain pipe 14 is fixedly connected to the outside of the cooling pool 8. The end of the drain pipe 14 away from the cooling pool 8 is fixedly connected to the outer wall of the cylinder 12. When it is necessary to filter the cooling water, the drain pipe 14 is opened so that the cooling water passes through the drain pipe 14 and then flows into the cylinder 12 for filtration.

[0039] Reference Figure 4 and Figure 5 The connecting rod 21 passes through and is slidably connected inside the cylinder 12. Multiple scrapers 23 are slidably connected to the inner wall of the filter cylinder 25. When the connecting rod 21 is driven, it will indirectly drive the scrapers 23 to slide on the inner wall of the filter cylinder 25, so that the impurities inside the filter cylinder 25 are always in motion during the filtration of cooling water, ensuring that the impurities will not clog the filter holes.

[0040] Reference Figure 3 and Figure 5The drain pipe 24 runs through the bottom of the cylinder 12. Impurities left by the cooling water filtration will fall into the drain pipe 24 due to gravity. Opening the drain pipe 24 allows for centralized treatment of the impurities. A second drain pipe 18 is fixedly connected to the outside of the cylinder 12. Opening the second drain pipe 18 allows the filtered cooling water to flow out, making it convenient for secondary use.

[0041] Reference Figure 5 The scraper 23 has multiple through holes 29 inside. By setting the through holes 29, the resistance from the cooling water can be effectively reduced during the up and down movement of the scraper 23.

[0042] Reference Figure 2 A handle 17 is fixedly connected to the top of the filter plate 27. By holding the handle 17, the filter plate 27 can be quickly removed, making it easy to replace.

[0043] Working principle: When the molten slag is cooled in the cooling pool 8, some waste gas is generated. This waste gas needs to be purified before being discharged. Therefore, during cooling, the exhaust fan 16 is started. The exhaust fan 16 will exhaust the air inside the box 11 and then form a suction force at the suction head 9, thereby drawing the waste gas generated during the cooling process into the connecting pipe 10 and then into the box 11. At this time, the waste gas will pass through the filter plate 27, and the harmful substances in the waste gas will be removed by the adsorption effect of the filter plate 27 before being discharged to the outside of the box 11, thereby reducing air pollution.

[0044] When cooling water needs to be recycled, the drain pipe 14 is opened, and the cooling water enters the cylinder 12 through the drain pipe 14, then flows onto the fixed ring 26, and then into the filter cylinder 25, thus filtering the cooling water. At this time, the motor 13 is started, which drives the turntable 19 to rotate, and then drives the cylinder 20 to rotate. The rotation of the cylinder 20 drives the frame 22 to move together with the cylinder 20, and then drives the connecting rod 21 to move up and down through the frame 22, which in turn drives the scraper 23 on the outer periphery of the connecting rod 21 to move up and down, so that the impurities inside the filter cylinder 25 are always in a flowing state, avoiding impurities clogging the filter holes and affecting the filtration effect. The filtered impurities fall into the drain pipe 24, and opening the drain pipe 24 can collect the impurities for convenient centralized treatment.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
