Description

Technical Field

[0001] This invention relates to the field of slag processing technology, and in particular to an upward-pushing hydraulic slag pusher. Background Technology

[0002] Coal slag is a type of industrial solid waste, the residue discharged from coal-fired power plants, industrial and domestic boilers, and other equipment. It is also known as furnace slag. Its main components are silicon dioxide, alumina, iron oxide, calcium oxide, and magnesium oxide. Depending on its composition, it can be used to manufacture cement, bricks, and refractory materials. Some types can be used to produce alumina or to refine rare metals such as gallium and germanium.

[0003] When coal slag is discharged from the equipment, it generates a large amount of dust and odor. When the slag discharge port of the equipment is high, the coal slag falling from the height will be broken up again. The broken coal slag will generate more dust and odor. A large amount of dust and odor will pose a serious threat to the health of the workers in the workshop, and will also generate a lot of falling noise. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that the dust and odor in coal slag pose a serious threat to the health of workers in the workshop, and to propose an upward-pushing hydraulic slag pusher.

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

[0006] A push-type hydraulic slag pusher includes an electric trolley and a slag storage box fixedly connected to the upper end of the electric trolley. An outer pipe communicating with the slag storage box is fixedly connected to the upper end, and a lifting pipe is inserted into the inner wall of the upper end of the outer pipe. A hydraulic cylinder is fixedly installed at the upper end of the slag storage box, and a lifting plate is fixedly connected to the telescopic end of the hydraulic cylinder. The lifting plate is fixedly connected to the outer wall of the lifting pipe. Two symmetrically arranged device slots are provided, and fan-shaped buffer plates are installed in the two device slots through a buffer mechanism. Suction hoods are installed on both sides of the inner top of the slag storage box.

[0007] To reduce noise and dust generated by slag, preferably, the buffer mechanism includes two protective covers fixedly connected to both sides of the outer wall of the outer tube. The two protective covers are respectively connected to two device slots. The upper end of the fan-shaped buffer plate is rotatably connected to the inner top of the device slot through a rotating rod. The fan-shaped buffer plate and the inner wall of the protective cover are elastically connected through an elastic element.

[0008] To further purify the dust and odor generated by the slag, a water tank is fixedly connected to the upper end of the slag storage box. The bottom of the water tank is equipped with a slag discharge pipe with multiple slag discharge ports. The slag discharge pipe is fixedly connected to and communicates with the air suction hood through an inverted U-shaped pipe. The water tank is equipped with a negative pressure component for suction.

[0009] To generate negative pressure in the water tank, the negative pressure assembly further includes an air intake pipe fixedly connected to the upper end of the water tank, the air intake pipe being connected to the inner top of the water tank, wherein the elastic element is an elastic airbag, an exhaust pipe fixedly connected to and communicating with the elastic element, and the upper end of the air intake pipe being fixedly connected to and communicating with the elastic element.

[0010] To further facilitate the reciprocating movement of the ash discharge pipe, a crossbar is slidably connected to the outer wall of the protective cover. One end of the crossbar is rotatably mounted with a pulley that abuts against the outer wall of the fan-shaped buffer plate. The other end of the crossbar extends into the water tank and is fixedly connected to a vertical plate. The ash discharge pipe is fixedly connected to the vertical plate, and the vertical plate is elastically connected to the inner wall of the water tank by a spring.

[0011] To further prevent dust and odors from escaping from the water tank and the slag tank, the upper end of both the slag tank and the water tank is provided with a strip-shaped groove. The two ends of the inverted U-shaped tube are respectively located in the two strip-shaped grooves. The inner wall of each of the two strip-shaped grooves is provided with a sliding cavity. A sealing plate is fixedly connected to each of the two sliding cavities. The two sealing plates are respectively fixedly connected to the outer walls of the two ends of the inverted U-shaped tube.

[0012] To further prevent blockage of the lifting pipe, a tapered rod is provided inside the upper port of the lifting pipe, with the pointed end of the tapered rod facing upwards. A vibration mechanism is provided inside the lifting pipe to drive the tapered rod to vibrate up and down.

[0013] To further drive the conical rod to vibrate up and down, the vibration mechanism includes an inclined tube fixedly connected to the outer wall of the lifting tube. The upper end of the inclined tube extends into the lifting tube and is fixedly connected to a blowpipe. The lower end of the conical rod is provided with a sliding hole. The upper end of the blowpipe is slidably inserted into the sliding hole and abuts against the inner top of the sliding hole. An exhaust gap is provided between the outer wall of the blowpipe and the inner wall of the sliding hole. The lower outer wall of the conical rod is provided with an exhaust hole communicating with the sliding hole. The inclined tube is fixedly connected to and communicates with the exhaust pipe through a connecting pipe.

[0014] To prevent the tapered rod from detaching from the blowpipe under air pressure, a limiting block is further fixedly connected to the outer wall of the blowpipe, and the limiting block is located inside the sliding hole.

[0015] To further facilitate more even steam discharge into the riser pipe, multiple exhaust holes are provided and are circumferentially distributed on the outer wall of the tapered rod.

[0016] Compared with the prior art, the present invention provides an upward-pushing hydraulic slag pusher, which has the following beneficial effects:

[0017] 1. This upward-pushing hydraulic slag pusher allows the slag to slide down over a fan-shaped buffer plate. The elastic element can buffer the top pressure on the fan-shaped buffer plate, thus buffering the impact force of the slag falling downward, making the slag less likely to be over-crushed, thereby reducing dust generation and noise generated when the slag falls.

[0018] 2. When the elastic element of this upward-pushing hydraulic slag pusher is not squeezed by the fan-shaped buffer plate, the suction hood will suck air into the slag storage box, thereby sucking the dust generated in the slag storage box into the ash discharge pipe, and then discharging it into the water tank from the ash discharge port on the ash discharge pipe. The liquid in the water tank can purify the air containing dust and odor, thereby reducing the harm of dust and odor to the workers.

[0019] 4. This upward-pushing hydraulic slag pusher creates negative pressure inside the slag storage box when the suction hood draws air into it. The slag storage box then draws air into the lifting pipe through the outer pipe, thus drawing in the dust and odor generated by the slag material into the slag storage box, further reducing the harm of dust and odor to workers.

[0020] 5. This upward-pushing hydraulic slag pusher uses a swinging fan-shaped buffer plate to drive the ash discharge pipe to slide back and forth in the water tank, which allows the liquid in the water tank to fully contact the dust, thus ensuring the purification of dust and odor.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0032] Example 1:

[0033] Reference Figures 1-8 A push-type hydraulic slag pusher includes an electric trolley 1 and a slag storage box 2, which is fixedly connected to the upper end of the electric trolley 1. The upper end of the slag storage box 2 is fixedly connected to an outer pipe 3 communicating with it, and a lifting pipe 4 is inserted into the inner wall of the upper end of the outer pipe 3. A hydraulic cylinder 5 is fixedly installed at the upper end of the slag storage box 2. The telescopic end of the hydraulic cylinder 5 is fixedly connected to a lifting plate 6, and the lifting plate 6 is fixedly connected to the outer wall of the lifting pipe 4. Two symmetrically arranged device slots 7 are provided, and fan-shaped buffer plates 9 are installed in the two device slots 7 through a buffer mechanism. Suction hoods 13 are installed on both sides of the inner top of the slag storage box 2.

[0034] In operation, the slag storage box 2 is moved below the slag discharge port of the equipment by the electric trolley 1, and the upper end of the lifting pipe 4 is aligned with the slag discharge port. Then, the lifting pipe 4 is moved upward by the hydraulic cylinder 5 until the upper end of the lifting pipe 4 covers the slag discharge port. Then, the gate on the equipment is opened, and the slag inside the equipment can fall into the lifting pipe 4 and be discharged into the slag storage box 2 through the outer pipe 3. When the slag passes through the outer pipe 3, the buffer mechanism can buffer the top pressure on the fan-shaped buffer plate 9, thus the fan-shaped buffer plate 9 can buffer the pressure. The impact force of the slag falling downwards prevents it from being over-crushed, thus reducing dust generation and noise. The suction hood 13 can suck air into the slag storage box 2, creating negative pressure inside. The slag storage box 2 then sucks air into the lifting pipe 4 through the outer pipe 3. As the slag slides into the lifting pipe 4, the dust and odors generated are sucked into the slag storage box 2 instead of drifting out from the upper end of the lifting pipe 4, further reducing the harm of dust and odors to workers.

[0035] Example 2:

[0036] Reference Figure 3 and Figure 6 Similar to Example 1, but further, a specific implementation scheme for the buffer mechanism is disclosed.

[0037] The buffer mechanism includes two protective covers 27 fixedly connected to both sides of the outer wall of the outer tube 3. The two protective covers 27 are respectively connected to two device slots 7. The upper end of the fan-shaped buffer plate 9 is rotatably connected to the inner top of the device slot 7 through the rotating rod 8. The fan-shaped buffer plate 9 and the inner wall of the protective cover 27 are elastically connected through the elastic element 10.

[0038] As the slag passes through the outer pipe 3, the downward-sliding slag slides over the fan-shaped buffer plate 9. Under the pushing action of the slag, the fan-shaped buffer plate 9 swings into the protective cover 27 via the rotating rod 8. The fan-shaped buffer plate 9 then squeezes the elastic element 10, which can buffer the top pressure on the fan-shaped buffer plate 9. Thus, the fan-shaped buffer plate 9 can buffer the impact force of the slag falling downward, making it less likely for the slag to be over-crushed, thereby reducing dust generation and noise generated when the slag falls. Since the slag is in clumps, the fan-shaped buffer plate 9 will be intermittently and irregularly collided with by the slag. When the fan-shaped buffer plate 9 is not collided with by the slag, the elastic element 10 will drive the fan-shaped buffer plate 9 to swing back and reset.

[0039] Example 3:

[0040] Reference Figures 1-6 The implementation is basically the same as in Example 2, but with a further addition of a specific implementation scheme for suction of air from the suction hood 13.

[0041] A water tank 14 is fixedly connected to the upper end of the slag storage box 2. A ash discharge pipe 15 is provided at the bottom of the inner side of the water tank 14. The ash discharge pipe 15 is provided with multiple ash discharge ports 16. The ash discharge pipe 15 is fixedly connected to and communicates with the suction hood 13 through an inverted U-shaped pipe 17. The water tank 14 is provided with a negative pressure assembly for suction. The negative pressure assembly includes a suction pipe 11 fixedly connected to the upper end of the water tank 14. The suction pipe 11 is connected to the inner top of the water tank 14. The elastic element 10 is an elastic airbag. An exhaust pipe 12 is fixedly connected to and communicates with the elastic element 10. The upper end of the suction pipe 11 is fixedly connected to and communicates with the elastic element 10.

[0042] When the elastic element 10 is squeezed by the fan-shaped buffer plate 9, the elastic element 10 will discharge the internal air through the exhaust pipe 12. When the elastic element 10 is not squeezed by the fan-shaped buffer plate 9, the elastic element 10 will elastically reset, thereby sucking air into the water tank 14 through the suction pipe 11. The water tank 14 will then reset, and the water tank 14 will suck air into the suction hood 13 through the inverted U-shaped pipe 17. The suction hood 13 will then suck air into the slag storage box 2, thereby sucking the dust generated in the slag storage box 2 into the ash discharge pipe 15, and then discharging it into the water tank 14 from the ash discharge port 16 on the ash discharge pipe 15. Since the ash discharge pipe 15 is located at the bottom of the water tank 14, the dust discharged from the ash discharge port 16 will pass through the liquid in the water tank 14. The liquid can purify the air containing dust and odor, thereby reducing the harm of dust and odor to the staff and preventing the suction pipe 11 from sucking dust into the elastic element 10.

[0043] In practice, the liquid in water tank 14 is a mixture of water and sodium hypochlorite. Water can absorb dust, and sodium hypochlorite can neutralize sulfur dioxide in odorous gases.

[0044] Example 4:

[0045] Reference Figures 3-7 The implementation is basically the same as in Example 3, but with a further addition: a specific implementation plan for driving the ash discharge pipe 15 to move back and forth.

[0046] A crossbar 21 is slidably connected to the outer wall of the protective cover 27. One end of the crossbar 21 is rotatably mounted with a pulley 24 that abuts against the outer wall of the fan-shaped buffer plate 9. The other end of the crossbar 21 extends into the water tank 14 and is fixedly connected to a vertical plate 22. The ash discharge pipe 15 is fixedly connected to the vertical plate 22. The vertical plate 22 and the inner wall of the water tank 14 are elastically connected by a spring 23.

[0047] When the fan-shaped buffer plate 9 swings into the protective cover 27, it will push the horizontal bar 21 towards the water tank 14. The horizontal bar 21 will then drive the ash discharge pipe 15 to move horizontally through the vertical plate 22. When the fan-shaped buffer plate 9 swings back to its original position away from the protective cover 27, the spring 23 will drive the vertical plate 22 and the horizontal bar 21 to move in opposite directions, thereby driving the ash discharge pipe 15 to move horizontally in the opposite direction. Thus, the reciprocating fan-shaped buffer plate 9 will drive the ash discharge pipe 15 to slide back and forth in the water tank 14, so that the liquid in the water tank 14 can fully contact the dust, thus ensuring the effect of purifying dust and odor.

[0048] Furthermore, both the upper ends of the slag storage tank 2 and the water tank 14 are provided with strip-shaped grooves 18, and the two ends of the inverted U-shaped tube 17 are respectively located in the two strip-shaped grooves 18. The inner walls of the two strip-shaped grooves 18 are provided with sliding cavities 19, and sealing plates 20 are fixedly connected in the two sliding cavities 19. The two sealing plates 20 are respectively fixedly connected to the outer walls of the two ends of the inverted U-shaped tube 17.

[0049] As the inverted U-shaped tube 17 moves back and forth with the ash discharge tube 15, the inverted U-shaped tube 17 will slide back and forth in the strip chute 18, and drive the sealing plate 20 to slide back and forth in the sliding cavity 19. The sealing plate 20 can prevent the air in the water tank 14 and the slag storage tank 2 from floating out of the strip chute 18.

[0050] Example 5:

[0051] Reference Figures 3-6 as well as Figure 8 The implementation is basically the same as in Example 4, but with a further addition of a specific implementation plan to prevent blockage in the lifting pipe 4.

[0052] A tapered rod 32 is provided inside the upper port of the lifting pipe 4, with the pointed end of the tapered rod 32 facing upward. A shaking mechanism is provided inside the lifting pipe 4 to drive the tapered rod 32 to shake up and down. The shaking mechanism includes an inclined tube 25 fixedly connected to the outer wall of the lifting pipe 4. The upper end of the inclined tube 25 extends into the lifting pipe 4 and is fixedly connected to a blowpipe 28. The lower end of the tapered rod 32 is provided with a sliding hole 29. The upper end of the blowpipe 28 is slidably inserted into the sliding hole 29, and the upper end of the blowpipe 28 abuts against the inner top of the sliding hole 29. An exhaust gap is provided between the outer wall of the blowpipe 28 and the inner wall of the sliding hole 29. The lower end of the tapered rod 32 is provided with an exhaust hole 30 communicating with the sliding hole 29. The inclined tube 25 is fixedly connected to and communicates with the exhaust pipe 12 through a connecting pipe 26.

[0053] Because the fan-shaped buffer plate 9 swings irregularly, the exhaust pipe 12 also exhausts gas intermittently and irregularly. When the exhaust pipe 12 exhausts gas, it discharges the gas into the inclined pipe 25 through the connecting pipe 26. The inclined pipe 25 discharges the gas into the sliding hole 29 through the blowpipe 28. The conical rod 32 is then lifted upward by the gas. At the same time, the gas is discharged from the exhaust hole 30 into the sliding hole 29. When the gas in the sliding hole 29 is exhausted, the conical rod 32 moves downward to reset. When the exhaust pipe 12 exhausts gas again, the conical rod 32 will be lifted upward again. Thus, the irregular exhaust pipe 12 will cause the conical rod 32 to be lifted upward intermittently, thereby preventing blockage in the lifting pipe 4 and ensuring the collection efficiency of the slag.

[0054] Furthermore, a limiting block 31 is fixedly connected to the outer wall of the blowpipe 28. The limiting block 31 is located inside the sliding hole 29. The limiting block 31 can prevent the tapered rod 32 from detaching from the blowpipe 28 under air pressure.

[0055] Furthermore, multiple exhaust ports 30 are provided and are distributed circumferentially on the outer wall of the conical rod 32. Since the slag will retain a large amount of residual heat, the gas entering the water tank 14 will heat the water. The heated water will evaporate, and the evaporated gas will be discharged into the sliding hole 29 through the exhaust pipe 12 and discharged from the exhaust port 30. The gas containing sodium hypochlorite can neutralize the sulfur dioxide in the slag, thereby further reducing the generation of odor. Moreover, the slag moistened by steam is less likely to generate dust. Multiple exhaust ports 30 can make the steam more evenly discharged into the riser pipe 4.

[0056] In operation, this upward-pushing hydraulic slag pusher moves the slag storage box 2 below the slag discharge port using an electric trolley 1, aligning the upper end of the lifting pipe 4 with the discharge port. Then, the hydraulic cylinder 5 drives the lifting pipe 4 upward until its upper end covers the discharge port. The gate on the equipment is then opened, allowing the slag inside to fall into the lifting pipe 4 and be discharged into the slag storage box 2 through the outer pipe 3. As the slag passes through the outer pipe 3, it slides over the fan-shaped buffer plate 9. The fan-shaped buffer plate 9, propelled by the slag, is then pushed by the rotating rod... When the fan-shaped buffer plate 9 swings inward into the protective cover 27, it will squeeze the elastic element 10. The elastic element 10 can buffer the top pressure on the fan-shaped buffer plate 9. Thus, the fan-shaped buffer plate 9 can buffer the impact force of the slag falling downward, making the slag less likely to be over-crushed, thereby reducing dust generation and noise generated when the slag falls. Since the slag is in clumps, the fan-shaped buffer plate 9 will be hit by the slag intermittently and irregularly. When the fan-shaped buffer plate 9 is not hit by the slag, the elastic element 10 will drive the fan-shaped buffer plate 9 to swing back and reset.

[0057] When the elastic element 10 is compressed by the fan-shaped buffer plate 9, the elastic element 10 will expel internal air through the exhaust pipe 12. When the elastic element 10 is no longer compressed by the fan-shaped buffer plate 9, the elastic element 10 will elastically reset, thereby drawing air into the water tank 14 through the suction pipe 11. The water tank 14 will then reset, and the water tank 14 will draw air into the suction hood 13 through the inverted U-shaped pipe 17. The suction hood 13 will then draw air into the slag storage box 2, thereby drawing the dust generated in the slag storage box 2 into the ash discharge pipe 15, and then discharging it into the water tank 14 from the ash discharge port 16 on the ash discharge pipe 15. Since the ash discharge pipe 15 is located at the inner bottom of the water tank 14... Therefore, the dust discharged from the ash discharge port 16 will pass through the liquid in the water tank 14. The liquid can purify the air containing dust and odor, thereby reducing the harm of dust and odor to the staff and preventing the suction pipe 11 from sucking dust into the elastic element 10. When the suction hood 13 sucks air into the slag storage box 2, a negative pressure will be generated in the slag storage box 2. The slag storage box 2 will then suck air into the lifting pipe 4 through the outer pipe 3. Thus, when the slag slides into the lifting pipe 4, the dust and odor generated will be sucked into the slag storage box 2 instead of floating out from the upper end of the lifting pipe 4, thereby further reducing the harm of dust and odor to the staff.

[0058] When the fan-shaped buffer plate 9 swings into the protective cover 27, it will push the horizontal bar 21 towards the water tank 14. The horizontal bar 21 will then drive the ash discharge pipe 15 to move horizontally through the vertical plate 22. When the fan-shaped buffer plate 9 swings back to its original position away from the protective cover 27, the spring 23 will drive the vertical plate 22 and the horizontal bar 21 to move in opposite directions, thereby driving the ash discharge pipe 15 to move horizontally in the opposite direction. Thus, the reciprocating fan-shaped buffer plate 9 will drive the ash discharge pipe 15 to slide back and forth in the water tank 14, so that the liquid in the water tank 14 can fully contact the dust, thus ensuring the effect of purifying dust and odor.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
