However, during the discharge process, the waste lubricating oil in the water-oil mixture easily adheres to the inner wall of the drainage pipe, especially at the bends, which can easily cause blockages, resulting in poor drainage and even serious consequences such as water entering the blast furnace.

Detailed Implementation

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

[0026] The following is combined Figures 1 to 4 This invention describes the cloth-feeding device 1 and the iron-making equipment.

[0027] Firstly, such as Figure 1 As shown, this embodiment provides a fabric application device 1, which includes a device body 10, a liquid receiving tray 20, and a purification component 30. The device body 10 has a working chamber 12. The liquid receiving tray 20 is located at the bottom of the device body 10. The liquid receiving tray 20 has a receiving cavity 21, which communicates with the working chamber 12. The purification component 30 includes an inlet pipe 31, a return pipe 32, a filter 33, and a pump body 34. One end of the inlet pipe 31 communicates with the receiving cavity 21, and the other end of the inlet pipe 31 communicates with the inlet 332 of the filter 33. One end of the return pipe 32 communicates with the outlet 334 of the filter 33, and the other end of the return pipe 32 communicates with the receiving cavity 21. The pump body 34 is located on the inlet pipe 31.

[0028] In this embodiment, the fabric-laying device 1 generally requires a cooling structure to cool the rotating body inside the working chamber 12 during operation. The cooling water generated during the cooling process flows to the liquid receiving tray 20 at the bottom under the action of gravity. Meanwhile, the lubricating waste oil inside the device body 10 also drips into the liquid receiving tray 20. In other words, the water stored in the liquid receiving tray 20 is a water-oil mixture formed by cooling water and lubricating waste oil.

[0029] The two ends of the inlet pipe 31 are connected to the accommodating cavity 21 and the inlet 332 of the filter 33, respectively. The two ends of the return pipe 32 are connected to the outlet 334 of the filter 33 and the accommodating cavity 21, respectively. The pump body 34 is located on the inlet pipe 31. That is to say, when the pump body 34 is started, the water-oil mixture in the accommodating cavity 21 can enter the filter 33 through the inlet pipe 31 and the inlet 332. After being filtered by the filter 33, it flows back to the accommodating cavity 21 through the outlet 334 and the return pipe 32, thereby realizing the purification treatment of the water stored in the docking liquid tray 20.

[0030] By setting up the purification component 30, the water stored in the receiving pan 20 can be purified, reducing the oil content in the water and improving the water quality. This effectively reduces the amount of oil entering the pipes when draining the water from the receiving pan 20, thus preventing drainage problems caused by pipe blockage and preventing water from entering the blast furnace.

[0031] Moreover, since the purified water flows back into the receiving tray 20 to form a closed loop, there is always a certain amount of water in the receiving tray 20, which can ensure the heat insulation effect of the receiving tray 20 on the bottom components of the fabric distribution device 1, improve the cooling capacity of the receiving tray 20, and help extend the service life of the fabric distribution device 1.

[0032] Optionally, the liquid receiving tray 20 is configured as a ring structure.

[0033] Optionally, the pump body 34 can be a pneumatic diaphragm pump, which can perform the function of pressurized suction and transfer of waste oil. Even if there are some impurities in the suction material, it will not affect the operation of the pump body 34. The pump body 34 operates intermittently.

[0034] In some embodiments, such as Figure 2 As shown, the inlet pipe 31 includes a first pipe section 312. The first pipe section 312 is located inside the receiving cavity 21 and communicates with the receiving cavity 21. One end of the first pipe section 312 is connected to the receiving tray 20, and the other end of the first pipe section 312 extends toward the side where the device body 10 is located.

[0035] It is understandable that, due to the different densities of waste oil and cooling water, the water in the receiving pan 20 will form a stratified structure, with most of the waste oil floating on top, forming the waste oil layer Y, and the cooling water located below, forming the cooling water layer X.

[0036] Since one end of the first pipe section 312 is connected to the receiving tray 20 and the other end extends towards the side where the device body 10 is located, that is, the end of the first pipe section 312 away from the cavity wall of the receiving cavity 21 extends upwards. Since the upper layer of water in the receiving tray 20 is the waste oil layer Y, by extending the end of the first pipe section 312 away from the cavity wall of the receiving cavity 21 into the waste oil layer Y, stable oil-water separation can be achieved by combining the actual situation of water and oil separation. This allows the pump body 34 to suck up as much waste oil as possible from the receiving tray 20 when it starts working, improving the purification efficiency of waste oil. When discharging the water in the receiving tray 20, it is beneficial to further reduce the amount of oil entering the pipeline.

[0037] Optionally, the first pipe segment 312 may include a bend.

[0038] Optionally, the first pipe section 312 is welded to the cavity wall of the accommodating cavity 21.

[0039] In some embodiments, such as Figure 2 As shown, the first pipe section 312 has a notch 314 at one end near the device body 10, and the notch 314 is recessed in the direction away from the device body 10.

[0040] In other words, a notch 314 is provided at one end of the first pipe section 312 away from the cavity wall of the receiving cavity 21, and the notch 314 is recessed downward, so that the end of the first pipe section 312 away from the cavity wall of the receiving cavity 21 can be a certain distance below the liquid surface of the waste oil layer Y, which makes it easier for the purification component 30 to absorb the waste oil.

[0041] In some embodiments, such as Figure 2 As shown, the receiving tray 20 is also provided with a purification channel 22, which is connected to the first pipe section 312. The inlet pipe 31 also includes a second pipe section 316. The second pipe section 316 is connected to the receiving tray 20 and is located on both sides of the purification channel 22, respectively, along with the first pipe section 312. The second pipe section 316 is connected to the purification channel 22.

[0042] In this embodiment, the first pipe section 312 and the second pipe section 316 are located on both sides of the purification channel 22, and the two ends of the purification channel 22 are connected to the first pipe section 312 and the second pipe section 316, respectively. Specifically, when the pump body 34 starts working, the water stored in the receiving pan 20 can pass through the first pipe section 312, the purification channel 22 and the second pipe section 316 in sequence, and enter the interior of the filter 33 through the inlet 332 of the filter 33. After being filtered by the filter 33, it flows back to the receiving cavity 21 through the outlet 334 and the return pipe 32, thereby achieving the purification treatment of the water stored in the receiving pan 20 and separating the waste oil from the cooling water.

[0043] Since the first pipe section 312 and the second pipe section 316 are located on both sides of the purification channel 22, that is, the liquid inlet pipe 31 is a split structure. Compared with extending a single pipe from the outside into the accommodating cavity 21, the radial width of the channel opened on the liquid receiving tray 20 can be reduced, which can improve the overall structural strength of the liquid receiving tray 20 and the connection strength between the liquid receiving tray 20 and the device body 10, and help extend the service life of the liquid receiving tray 20.

[0044] In some embodiments, such as Figure 2 As shown, the liquid receiving tray 20 includes a fixing member 23 and a tray body 24. The fixing member 23 is connected to the device body 10. The fixing member 23 is provided with a purification channel 22. The first pipe section 312 and the second pipe section 316 are respectively connected to the fixing member 23. The tray body 24 is located on the side of the fixing member 23 away from the device body 10 and is connected to the fixing member 23. The tray body 24 and the fixing member 23 form a receiving cavity 21.

[0045] In this embodiment, the fixing member 23 is connected to the device body 10, and the disc 24 is connected to the fixing member 23. That is, the disc 24 is fixedly installed at the bottom of the device body 10 by the fixing member 23, thereby realizing the collection of cooling water.

[0046] The disc body 24 and the fixing member 23 form a receiving cavity 21, which can increase the capacity of the receiving cavity 21 and is conducive to improving the heat insulation effect of the liquid receiving disc 20 on the bottom device of the cloth spreading device 1.

[0047] Optionally, the first pipe section 312 and the second pipe section 316 are fixed to the fastener 23 by welding.

[0048] Optionally, the disc body 24 and the fastener 23 can be connected by welding, which can improve the sealing performance at the connection between the disc body 24 and the fastener 23.

[0049] Optionally, the fastener 23 may include a flange.

[0050] In some embodiments, such as Figure 2 As shown, the fixing member 23 has a limiting groove 232 on the side opposite to the receiving cavity 21. One end of the second pipe section 316 is inserted into the limiting groove 232 and connected to the groove wall of the limiting groove 232.

[0051] Embedding one end of the second pipe section 316 into the limiting groove 232 helps improve the installation stability of the second pipe section 316. At the same time, it can also improve the sealing of the connection between the second pipe section 316 and the fixing member 23, preventing the water in the liquid receiving tray 20 from leaking during the purification process.

[0052] In some embodiments, such as Figure 2 , Figure 3 and Figure 4As shown, the liquid receiving tray 20 also includes a heat insulation part 25. The heat insulation part 25 is provided on the side of the tray body 24 away from the fixing member 23.

[0053] It is understandable that the bottom of the material distribution device 1 generally has components. Since the liquid receiving tray 20 contains water, it has a certain heat insulation capacity. By setting a heat insulation part 25 on the side of the tray body 24 away from the fixing member 23, that is, setting a heat insulation part 25 at the bottom of the tray body 24, the heat insulation effect can be further improved, reducing the heat transfer of the material distribution device 1 to the outside, which is conducive to improving the reliability of the entire ironmaking equipment.

[0054] Optionally, the heat insulation part 25 includes a heat insulation cavity, which is filled with heat insulation material to improve the heat insulation effect.

[0055] In some embodiments, such as Figure 1 As shown, the purification assembly 30 also includes a first valve body 35 and a second valve body 36. The first valve body 35 is disposed on at least one of the inlet pipe 31 and the inlet 332, and is used to control the connection or disconnection between the inlet pipe 31 and the inlet 332. The second valve body 36 is disposed on at least one of the return pipe 32 and the outlet 334, and is used to control the connection or disconnection between the return pipe 32 and the outlet 334.

[0056] After prolonged use, in order to ensure the filtering effect of filter 33 on waste oil, the filter element inside filter 33 generally needs to be replaced.

[0057] Specifically, when the filter element needs to be replaced, the first valve body 35 and the second valve body 36 can be controlled to be in the closed state to begin the filter element replacement. After the filter element replacement is completed, the first valve body 35 and the second valve body 36 can be controlled to be in the open state to achieve purification treatment of the water stored in the docking liquid tray 20. By setting the first valve body 35 and the second valve body 36, the replacement of the filter element can be facilitated.

[0058] In some embodiments, such as Figure 4 As shown, the return pipe 32 is connected to the device body 10. One end of the return pipe 32 bends and extends toward the side where the receiving tray 20 is located, and is positioned opposite the opening of the receiving cavity 21.

[0059] In this embodiment, the return pipe 32 is fixed to the device body 10. One end of the return pipe 32 is bent downwards and is positioned opposite to the opening of the accommodating cavity 21, so that when the purified cooling water flows back into the accommodating cavity 21 through the return pipe 32, splashing can be reduced.

[0060] In some embodiments, such as Figure 3As shown, the fabric application device 1 also includes a drain assembly 40. The drain assembly 40 is disposed on the liquid receiving tray 20 and communicates with the receiving cavity 21. The drain assembly 40 includes a liquid guide tube 42, which is located inside the receiving cavity 21. One end of the liquid guide tube 42 is connected to the liquid receiving tray 20, and the other end of the liquid guide tube 42 extends away from the device body 10.

[0061] Since the drain assembly 40 is connected to the accommodating cavity 21, when the water in the receiving tray 20 reaches a certain level, it can be drained through the drain assembly 40.

[0062] It is understandable that, due to the different densities of waste oil and cooling water, the water in the receiving pan 20 will form a stratified structure, with most of the waste oil floating on top, forming the waste oil layer Y, and the cooling water located below, forming the cooling water layer X.

[0063] The drain assembly 40 includes a liquid guide pipe 42 located within the receiving cavity 21, with one end of the liquid guide pipe 42 extending downwards away from the cavity wall of the receiving cavity 21. Since the lower layer of water in the receiving pan 20 is the cooling water layer X, extending the end of the liquid guide pipe 42 away from the cavity wall of the receiving cavity 21 into the cooling water layer X allows for maximum separation of waste oil and cooling water, taking into account the actual situation of water and oil stratification. This further reduces the oil content in the drain pipe 44 (pipeline), prevents pipe blockage, and prevents water from entering the blast furnace.

[0064] Optionally, the liquid guide tube 42 is welded to the cavity wall of the accommodating cavity 21.

[0065] In some embodiments, such as Figure 2 and Figure 3 As shown, the drain assembly 40 and the inlet pipe 31 are located on different sides of the receiving tray 20.

[0066] In this embodiment, since the drain assembly 40 and the inlet pipe 31 are located on different sides of the receiving tray 20, they can achieve the drain function and the purification function respectively while avoiding interference, which is beneficial to improving the overall reliability of the fabric device 1.

[0067] What is understandable is that Figure 1 The two device bodies 10 in the figure are cross-sectional views of the same structure at different positions.

[0068] In some embodiments, such as Figure 3 As shown, the drainage assembly 40 also includes a drainage pipe 44 and a water seal system 46. The drainage pipe 44 is located outside the receiving cavity 21 and is connected to the receiving tray 20. One end of the drainage pipe 44 is connected to the liquid guide pipe 42. The water seal system 46 is connected to the other end of the drainage pipe 44.

[0069] When the water level in the receiving pan 20 reaches a certain level, the cooling water in the cooling water layer X flows sequentially through the liquid guide pipe 42 and the drain pipe 44 to the water seal system 46, thereby discharging the stored water. It can be understood that the cooling water flowing to the water seal system 46 can be further processed and used to cool the rotating body inside the fabric spreading device 1.

[0070] In one specific embodiment, the continuous charging device (charging device 1) applied to the blast furnace top charging system is an important component of the blast furnace ironmaking equipment. Its core equipment can realize single-ring, multi-ring, spiral, fan-shaped, and fixed-point charging patterns, and can realize the arrangement of furnace materials such as coal, coal briquettes, coke, sinter, pellets, lump ore, undersize ore, and sponge iron on the furnace surface. The pressure inside the charging device (charging device 1) is approximately 0.25 MPa.

[0071] Specifically, the material distributor (material distribution device 1) mainly includes a drain pipe (drainage pipe 44), a water cooling plate (receiving plate 20), a U-shaped water seal system (water seal system 46), a sewage pump (pump body 34), and a filter 33.

[0072] The receiving tray 20 holds the industrial water cooled by the open cooling of the material distributor (material distribution device 1). Simultaneously, waste oil generated from lubrication inside the material distributor drips onto the water-cooling tray (receiving tray 20). Due to the density difference between the waste oil and cooling water, most of the waste oil floats on the surface, resulting in stratification. The original drainage pipe of the material distributor (material distribution device 1) remains unchanged; only a bend (liquid guide pipe 42) is added at the water inlet inside the water-cooling tray (receiving tray 20) to allow clean water from the water-cooling tray to flow along the drain pipe (drain pipe 44) into the U-shaped water seal pipe (water seal system 46). When the water in the receiving tray 20 accumulates to a certain height, it flows out of the U-shaped water seal pipe outside the material distributor. By setting the bend (liquid guide pipe 42), it is ensured that only clean water from the receiving tray 20 flows through the drain pipe (drain pipe 44).

[0073] The suction port of the oil suction pipe (first pipe section 312) faces upward, but must be a certain distance below the liquid surface to draw the waste oil in the water cooling plate (liquid receiving plate 20) into the sewage pump (pump body 34). The waste oil flows through the filter 33, and the filtered clean water flows back to the inside of the distributor through the return water pipe (return liquid pipe 32), forming a closed loop.

[0074] In addition, by returning the filtered clean water to the water cooling pan (receiving pan 20) through the return water pipe (return liquid pipe 32), the liquid level in the water cooling pan can be kept stable, and the water in the water cooling pan will not dry out even if the distributor (distribution device 1) stops supplying water.

[0075] The inlet of the oil suction pipe (first pipe section 312) is located below the waste oil layer Y and above the clean water layer (cooling water layer X). The waste oil is continuously drawn in and transferred to the filter 33 by the suction of the sewage pump (pump body 34). The filter 33 can also be a self-cleaning filter.

[0076] By improving the pipe orientation of the fabric distribution equipment (fabric distribution device 1), adding bends, adding sewage pumps and filters, etc., and by cleverly layering the pipe inlet and outlet, combined with the actual situation of oil and water separation, stable oil-water separation can be achieved, reducing the oil content in the U-shaped water seal pipe, thereby avoiding pipe blockage.

[0077] At the same time, the waste oil in the water cooling pan is cleaned out of the distributor in a timely and effective manner. Under pressure, the cooling water in the water cooling pan is purified online, which improves the water quality in the water cooling pan, enhances the cooling capacity of the water cooling pan, and extends the service life of the distributor.

[0078] Secondly, this embodiment provides an ironmaking apparatus, including the feeding device 1 of the first aspect embodiment described above. Since the ironmaking apparatus shown in this embodiment includes the feeding device 1 of the first aspect embodiment, it possesses all the beneficial technical effects of the feeding device 1, and will not be elaborated further here.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
