Description

Technical Field

[0001] This invention relates to the technical field of industrial slag removal and cooling equipment, specifically to a device for removing industrial waste. Background Technology

[0002] In the metallurgical, power, and chemical industries, slag is one of the main industrial wastes generated during production. The amount generated is enormous, and improper handling can not only occupy a large amount of land resources, but also pollute the soil and water bodies due to the seepage of harmful substances contained in the slag. Therefore, timely treatment and resource utilization of slag has become an indispensable and important link in industrial production. When slag is discharged from industrial equipment such as smelting furnaces and boilers, it is usually in a high-temperature molten state or a high-temperature solid state, with temperatures reaching 800-1200℃. Such high temperatures make it impossible for slag to be directly transferred, crushed, sorted, and recycled. It must first be cooled down to a safe operating range (usually not exceeding 100℃) before it can enter the next processing stage.

[0003] Currently, the most widely used and mature method for cooling high-temperature slag in the industry is to use a cooling pool for natural or forced cooling. The core process is as follows: the high-temperature slag discharged from the industrial equipment is directly discharged to the surface of the water in the cooling pool through a conveying mechanism. The cooling water stored in the cooling pool exchanges heat with the high-temperature slag to cool it down. After the slag is cooled to the specified temperature, the slag floating or accumulated on the water surface is scraped off to a designated collection area by a slag scraping mechanism set above or on the side of the cooling pool, thus completing the cooling and initial separation of the slag.

[0004] However, the existing slag cooling methods have many technical defects, the most prominent of which is the poor cooling effect and low cooling efficiency of the slag, which makes it difficult to meet the needs of large-scale industrial production.

[0005] Specifically, since the high-temperature slag is directly discharged onto the surface of the cooling pool, and the slag itself has certain accumulation characteristics, as subsequent slag is continuously discharged, the slag that has entered the cooling pool will gradually accumulate on the water surface, forming a thick slag layer. At this time, only the slag at the bottom of the slag layer can directly contact the cooling water to carry out sufficient heat exchange and achieve rapid cooling. However, the slag at the top of the slag layer is difficult to effectively contact the cooling water, and the heat inside it is difficult to dissipate, resulting in an extremely slow cooling rate for this part of the slag. Summary of the Invention

[0006] Therefore, the purpose of this invention is to provide a device for removing industrial waste, so as to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a device for removing industrial waste, comprising a cooling pool, a discharge pipe, a cooling box, a circulating filter water box and a cooling fan assembly, wherein a rotating cylinder is provided in the cooling pool, and rotating blades are provided on the outer wall of the rotating cylinder for pressing slag into the bottom of the cooling water and conveying it into the rotating cylinder, and a rotating rod is rotatably connected inside the rotating cylinder, and a spiral discharge plate is provided on the rotating rod for pushing the slag axially.

[0008] The rotating drum has a feed inlet for slag and cooling water to enter, and two sets of feed inlets and two sets of rotating blades are set accordingly. The two ends of the rotating drum and the cooling pool are supported by bearings, and a sealing ring is provided on the outside of the bearing.

[0009] The rotating blades have hollowed-out grooves, and the spiral discharge blades have hollowed-out holes;

[0010] The rotating cylinder and the rotating rod are respectively connected to the driving mechanism and driven by the driving mechanism to form a speed difference, so as to realize the stable conveying and discharge of slag. The driving mechanism includes a motor, a transmission rod, a driving belt, a first pinion, a first large gear, a second large gear and a second pinion;

[0011] The first pinion and the first large gear are coaxially fixed on the transmission rod, and the transmission rod and the motor output end are connected by a drive belt;

[0012] The second large gear is fixed to one end of the outer side of the rotating cylinder, and the second small gear is fixed to the outer side of the rotating rod;

[0013] The first small gear meshes with the second large gear, and the first large gear meshes with the second small gear, so that the rotational speed of the rotating rod is greater than the rotational speed of the rotating cylinder;

[0014] A discharge pipe is fixedly connected to one side of the cooling pool and movably connected to the rotating drum. One end of the discharge pipe is at a higher horizontal level than the end near the rotating drum, and the outlet of one end of the discharge pipe corresponds to the external conveying equipment.

[0015] The discharge pipe has a drain hole at the bottom and is connected to the cooling box through a connecting pipe. The cooling box has a cooling chamber inside and strip-shaped ventilation holes that intersect with the cooling chamber for ventilation and heat dissipation. The cooling box works with a cooling fan assembly to cool the cooling water. The cooling fan assembly is located on one side of the cooling box and is used to force the cooling water in the cooling chamber to be cooled by air.

[0016] The cooling tank is connected to the circulating filter water tank. The circulating filter water tank sends the cooled and filtered water back to the bottom of the cooling pool through the water inlet pipe, forming a cooling water circulation filtration and cooling system, thereby realizing the immersion cooling, continuous conveying, solid-liquid separation and water recycling of the slag. The circulating filter water tank has a built-in filter structure and circulating water pump, which is used to filter the ash and transport the cooling water back to the cooling pool.

[0017] The water inlet rate of the inlet pipe is balanced with the water outlet rate of the outlet to maintain a stable liquid level in the cooling pool.

[0018] A fixed cylinder is provided on the outside of the rotating cylinder, and the fixed cylinder is used to fix and install the drive mechanism. The end of the fixed cylinder is threadedly connected to an end cap, and the bottom of the cooling pool is provided with support legs.

[0019] In summary, the present invention has the following main beneficial effects:

[0020] 1. This invention effectively prevents slag from accumulating on the surface of the cooling pool by forcibly pressing high-temperature slag into the cooling water for immersion cooling, ensuring full contact between the slag and the cooling water, greatly improving the cooling efficiency and uniformity. It fundamentally solves the problem that the top layer of slag is difficult to make effective contact with the cooling water in traditional methods, ensuring rapid and uniform cooling of the slag as a whole, significantly shortening the cooling cycle, ensuring continuous and stable operation of subsequent processes such as transfer, crushing, and sorting, and improving the overall treatment efficiency of industrial waste.

[0021] 2. This invention ensures that the slag is fully cooled before being discharged, avoiding damage to equipment or secondary heat release from uncooled high-temperature slag, eliminating safety hazards, and improving the safety of production operations; combined with a cooling water circulation filtration and active cooling system, it realizes the recycling of water resources, reduces ineffective heat loss and water waste, and is more energy-efficient and environmentally friendly.

[0036] The embodiments of the present invention will now be described.

[0037] Example 1

[0038] like Figure 1-7 As shown, an industrial waste removal device includes a cooling pool 1, a rotating cylinder 2, rotating blades 3, rotating rods 5, spiral discharge plates 6, a drive mechanism 7, a discharge pipe 8, a cooling box 9, a circulating filter water tank 10, and a cooling fan assembly 16. The rotating cylinder 2 is installed inside the cooling pool 1, and rotating blades 3 are fixedly connected to the outer wall of the rotating cylinder 2. The rotating rod 5 is installed inside the rotating cylinder 2, and spiral discharge plates 6 are fixedly connected to the outer side of the rotating rod 5.

[0039] The two ends of the rotating cylinder 2 are rotatably connected to the cooling pool 1 by bearings 4. A sealing ring is provided on the outer side of the bearing 4. The outer wall of the rotating cylinder 2 is provided with a feed inlet 201. The feed inlet 201 is provided with the rotating blade 3. The outer wall of the rotating blade 3 is provided with a hollow groove 301. The outer wall of the spiral discharge plate 6 is provided with a hollow hole 601.

[0040] A discharge pipe 8 is fixedly connected to one side of the cooling pool 1. The discharge pipe 8 is movably connected to the rotating cylinder 2. A drain hole 801 is opened at the bottom of the discharge pipe 8. The horizontal height of the end of the discharge pipe 8 away from the rotating cylinder 2 is higher than the horizontal height of the end close to the rotating cylinder 2.

[0041] The drive mechanism 7 includes a motor 701, a transmission rod 702, a drive belt 703, a first pinion 704, a first large gear 705, a second large gear 706, and a second pinion 707. The output end of the motor 701 is connected to the transmission rod 702 via the drive belt 703. The first pinion 704 and the first large gear 705 are coaxially fixed to the outer side of the transmission rod 702. The second large gear 706 is fixedly connected to the outer side of the rotating cylinder 2, and the second pinion 707 is fixedly connected to the outer side of the rotating rod 5. The first pinion 704 and the second large gear 706 mesh with each other, and the first large gear 705 and the second pinion 707 mesh with each other, so that the rotational speed of the rotating rod 5 is greater than the rotational speed of the rotating cylinder 2.

[0042] A cooling box 9 is provided on the outside of the cooling pool 1. A cooling chamber 901 is provided inside the cooling box 9. A strip-shaped ventilation hole 902 is provided on the side wall of the cooling box 9. A cooling fan assembly 16 is provided on one side of the cooling box 9.

[0043] The cooling chamber 901 is connected to the drain hole 801 through the connecting pipe 11. One end of the cooling box 9 is connected to the circulating filter water tank 10. The circulating filter water tank 10 is equipped with a filter structure and a circulating water pump. The circulating filter water tank 10 is connected to the bottom of the cooling pool 1 through the water inlet pipe 12. The water inlet speed of the water inlet pipe 12 and the water outlet speed of the drain hole 801 are balanced.

[0044] A fixed cylinder 13 is provided on the outside of the rotating cylinder 2. The fixed cylinder 13 is fixedly connected to the drive mechanism 7. An end cap 14 is threadedly connected to the end of the fixed cylinder 13. A support leg 15 is fixedly connected to the bottom of the cooling pool 1.

[0045] The working principle of this invention is as follows: When in use, the device is placed below the slag discharge pipe so that the slag is directly discharged into the cooling pool 1, wherein the liquid level of the cooling water inside the cooling pool 1 is slightly lower than the horizontal height of the axis of the rotating cylinder 2.

[0046] As slag continues to enter the cooling pool 1, the drive mechanism 7 will drive the rotating cylinder 2 and two sets of rotating blades 3 to rotate continuously. The continuously rotating blades 3 can press the slag entering the cooling pool 1 into the bottom of the cooling pool 1. As the rotating blades 3 rotate, when a set of rotating blades 3 carries a part of the slag from the bottom of the cooling pool 1 to the top and leaves the cooling water surface, the slag will enter the interior of the rotating cylinder 2 through the feed port 201 corresponding to the rotating blades 3 under its own gravity.

[0047] The slag entering the rotating drum 2 will be moved from one end to the other along the axis of the rotating drum 2 by the rotation of the spiral discharge plate 6, and then the cooled slag will enter the discharge pipe 8. The horizontal height of one end of the discharge pipe 8 is higher than the horizontal height of the end near the rotating drum 2. As the spiral discharge plate 6 rotates, it gradually pushes the slag into the discharge pipe 8. At this time, the cooled slag can be continuously discharged from the pipe opening at one end of the discharge pipe 8 to the external conveying equipment.

[0048] Furthermore, the motor 701 of the drive mechanism 7 drives the transmission rod 702 to rotate via the drive belt 703. A first small gear 704 and a first large gear 705 are coaxially fixed on the outside of the transmission rod 702. The first small gear 704 meshes with the second large gear 706 fixed on the outside of the rotating cylinder 2, and the first large gear 705 meshes with the second small gear 707 fixed on the outside of the rotating rod 5. In other words, the rotation speed of the rotating rod 5 is greater than that of the rotating cylinder 2, thereby creating a speed difference between the rotating cylinder 2 and the spiral discharge plate 6. This ensures that the slag can be gradually discharged by the spiral discharge plate 6 after entering the rotating cylinder 2.

[0049] Furthermore, two sets of feed inlets 201 are provided on the rotating drum 2. When one set of feed inlets 201 rotates to below the cooling water level, some of the cooling water can carry a portion of large slag particles and fine ash into the rotating drum 2 through this set of feed inlets 201. Then, the cooling water will flow into the discharge pipe 8. The discharge pipe 8 has a drain hole 801 at the bottom. The cooling water will carry fine ash through the drain hole 801 to the connecting pipe 11, while the large slag particles carried at this time will remain inside the discharge pipe 8 and merge with the slag pushed by the spiral discharge plate 6. The whole thing is discharged through one end of the discharge pipe 8.

[0050] The cooling water carrying fine furnace ash will enter the cooling chamber 901 in the cooling box 9 through the connecting pipe 11. A cooling fan assembly 16 is installed on one side of the cooling box 9. Under the action of the cooling fan assembly 16, the cooler airflow from the outside passes through the strip ventilation hole 902 of the cooling box 9, thereby actively cooling the cooling water inside the cooling chamber 901 after absorbing high temperature.

[0051] The cooled water will enter the circulating filter water tank 10, which contains a circulating water pump and filter bags. The filter bags can filter and intercept fine furnace ash, while the circulating water pump will transport the cooled water from the bottom of the cooling pool 1 to its interior through the water inlet pipe 12, forming an overall cooling water circulation process.

[0052] Specifically, compared to the slag that has just been discharged, the cooler water enters from the bottom of the cooling pool 1. At this time, the cooling water inside the cooling pool 1 flows from bottom to top and then comes into contact with the high-temperature slag that has been pressed into the cooling water by the rotating blades 3, thereby exchanging heat. The cooling water that has completed the heat exchange will flow into the cooling box 9 through the rotating cylinder 2 and the discharge pipe 8. At this time, the cooling water completes the heat dissipation and cooling operation again and continues to enter the cooling pool 1 again through the water inlet pipe 12.

[0053] Furthermore, the drainage speed of the drain hole 801 is balanced with the water inlet speed of the inlet pipe 12 to avoid the problem of excessive cooling water level inside the cooling pool 1 leaking from the discharge pipe 8.

[0054] In summary, the present invention uses rotating blades 3 to force high-temperature slag into the bottom of cooling pool 1, so that the slag is fully submerged in cooling water throughout the process, avoiding the accumulation of heat insulation layer on the water surface. All slag can fully and evenly contact the cooling water, fundamentally eliminating the problem of heat dissipation in the inner layer of slag. The cooling speed is significantly improved, and slag at 800–1200℃ can be quickly reduced to a safe operating temperature below 100℃.

[0055] This invention enables continuous operation of slag feeding, cooling, and slag discharge simultaneously, eliminating the need to wait for the slag to cool layer by layer, significantly shortening the overall processing cycle, and adapting to the large-scale and continuous production needs of industries such as metallurgy, power, and chemicals, thereby significantly improving the processing efficiency of the entire slag removal and cooling production line.

[0056] The slag is fully cooled inside the device before being discharged, preventing the direct discharge of uncooled, high-temperature slag. This avoids damage to the conveying equipment due to high temperatures and prevents secondary heat release during subsequent processing, significantly reducing production safety risks and improving operational safety and equipment lifespan.
