Description

Technical Field

[0001] This invention relates to the technical field of environmental protection equipment, and in particular to a converter dust removal circulating water sludge dewatering and extrusion device. Background Technology

[0002] In the steel smelting industry, dust removal water is mainly supplied to dust removal equipment, washing towers, spray guns, nozzles, and venturi nozzles. The water is atomized and wets the dust, causing it to agglomerate. Under the action of inertial collision, centrifugal force, and gravity, the captured dust is discharged through the drainage water seal of the washing tower and the elbow dewatering device, forming wastewater. At this time, the wastewater contains a large number of floating impurities. The wastewater enters the sedimentation tank through the drainage chute. The organic polymer flocculant polyacrylamide is added to the sedimentation tank to flocculate and precipitate the impurities in the wastewater. The supernatant water after sedimentation overflows back to the water tank. The water in the return water tank is then pumped to the cooling tower by the cooling pump and then flows back to the feed water tank for reuse. The settled sludge is dewatered by the extrusion dewatering equipment and then sent to the sintering plant for sintering.

[0003] During sludge dewatering, the sludge contains a large amount of water and is highly fluid. It is transported to the filter cartridge by a pump, where it is intercepted. The water in the sludge passes through the cartridge and is discharged. As the pump continues to pressurize, the pressure inside the filter cartridge increases, creating a squeezing dewatering effect. However, this dewatering method is problematic because particulate matter in the sludge can clog the filter cartridge, preventing it from being used continuously for extended periods and requiring regular cleaning. This significantly impacts work efficiency. Furthermore, the equipment must be shut down when the dewatered sludge is discharged from the filter cartridge, making continuous dewatering impossible. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a converter dust removal circulating water sludge dewatering and extrusion device, the specific technical solution of which is as follows:

[0005] A converter dust removal circulating water sludge dewatering and extrusion device includes a horizontal cylinder, a vertical pipe and a feeding pipe. The horizontal cylinder is horizontal, and the vertical pipe is vertically installed in the middle of the horizontal cylinder. The horizontal cylinder and the vertical pipe are connected and the horizontal cylinder rotates on the vertical pipe. The number of feeding pipes is set to two, and the two feeding pipes are respectively connected and installed on the left and right sides of the horizontal cylinder.

[0006] A connecting column is coaxially provided in the middle of the cross cylinder, and coarse mesh plates are provided at both ends of the connecting column;

[0007] The connecting column and the two coarse mesh plates reciprocate along the axis of the horizontal cylinder.

[0008] Furthermore, a support column is coaxially provided inside the vertical tube. The support column is fixedly connected to the vertical tube. The end of the support column extends into the horizontal cylinder. A disc is provided at the end of the support column. An eccentric column is eccentrically provided on the disc. A long groove is horizontally provided in the middle of the connecting column. The length direction of the long groove is perpendicular to the length direction of the connecting column. The eccentric column is slidably installed in the long groove.

[0009] Furthermore, the end of the horizontal cylinder is provided with a discharge structure for discharging dewatered sludge. The discharge structure includes a discharge channel, which is connected to the horizontal cylinder. A side channel is inclinedly provided on the side wall of the discharge channel. A sealing column is slidably provided in the discharge channel to block the side channel. The sealing column is connected to the discharge channel by a spring.

[0010] A drainage pipe is installed on the vertical pipe.

[0011] Furthermore, the horizontal cylinder consists of an intermediate cylinder located in the middle and two side cylinders installed at both ends of the intermediate cylinder, with the vertical pipe installed on the intermediate cylinder and the discharge channel installed inside the side cylinders;

[0012] The middle cylinder and the side cylinder are connected by a rotating ring, and the rotating ring can rotate on the middle cylinder and the side cylinder. A connecting plate is fastened to the outside of the rotating ring. The connecting plate is used to connect and fix the middle cylinder and the side cylinder. A fine mesh plate is provided inside the rotating ring. The fine mesh plate is provided with a cleaning structure for backwashing local rotating rings.

[0013] The connecting column passes through the fine mesh plate and slides relative to it.

[0014] Furthermore, the cleaning structure includes two baffles, which are distributed at an angle. The two baffles and the inner wall of the middle cylinder form a cylindrical shape, and a movable plate is slidably disposed therein. A first transmission wheel is driven inside the rotating ring. The first transmission wheel is connected to the movable plate by a connecting rod. One end of the connecting rod is eccentrically mounted on the first transmission wheel, and the other end of the connecting rod is rotatably mounted on the movable plate.

[0015] Furthermore, a retainer is fastened to the first drive wheel, the first drive wheel rotates on the retainer, and the retainer is fixed to the inner wall of the cross cylinder;

[0016] The movable plate has an opening in the middle, and a sealing plate is provided on the side wall of the movable plate facing the fine mesh plate. The sealing plate blocks the opening, and the sealing plate and the movable plate are connected by a spring.

[0017] Furthermore, it also includes a connecting plate, a column, and a fixed plate. The connecting plate is fixed to the bottom of the intermediate cylinder, the column supports the fixed plate, and the connecting plate is rotatably mounted on the fixed plate. The fixed plate is equipped with a motor and a second transmission wheel for providing power to the connecting plate.

[0018] The bottom of the rotating ring makes transmission contact with the top of the fixed disk.

[0019] Furthermore, a cavity is formed inside the column, and a feeding pipe is connected to the cavity. Multiple guide ports connected to the cavity are formed on the outer wall of the column.

[0021] The bottom surface of the outer casing is inclined, and a discharge port is provided on the outer casing. The sludge discharged from the side channel falls onto the inclined surface at the bottom of the outer casing and is discharged through the discharge port.

[0022] The advantages of this invention are:

[0023] By utilizing the rotation of the horizontal cylinder to achieve centrifugal dewatering of sludge, the structure and equipment for pressurizing sludge can be saved. Furthermore, due to the shape limitation of the horizontal cylinder, the sludge collection effect can be improved, and the compactness between sludge particles can be increased, making it easier for sludge particles to squeeze against each other, thereby improving the dewatering effect. Moreover, its structure and operation are simple, and the dewatering effect is good.

[0024] By utilizing the continuous feeding pipe and the continuous drainage of the vertical pipe, the sludge can be processed without interruption, and there is no need to worry about clogging. This avoids the problems of regular cleaning and repeated sludge discharge required in traditional methods, and significantly improves work efficiency and equipment uptime.

[0025] The rotation of the horizontal cylinder not only generates centrifugal force, which helps in the initial separation of mud and water and the coagulation of sludge, but also applies additional mechanical compression to the sludge deposited at the end of the horizontal cylinder through the coarse mesh plate, which can achieve the re-dewatering of the coagulated sludge. This facilitates the dewatering treatment of sludge in different forms and improves the dewatering effect.

[0026] In summary, this converter dust removal circulating water sludge dewatering and extrusion equipment, through its innovative design, solves the problems of low efficiency and frequent maintenance found in traditional sludge dewatering equipment, improves the dewatering effect, and reduces operating costs. It is of great significance for improving the efficiency and environmental performance of wastewater treatment in the steel industry. Attached Figure Description

[0038] 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.

[0039] In the description of this invention, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientations or positional relationships 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.

[0040] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0041] like Figures 1 to 3 As shown, a converter dust removal circulating water sludge dewatering and extrusion device of the present invention includes a horizontal cylinder 1, a vertical pipe 2 and a feeding pipe 3. The horizontal cylinder 1 is horizontal, and the vertical pipe 2 is vertically installed in the middle of the horizontal cylinder 1. The horizontal cylinder 1 is connected to the vertical pipe 2 and the horizontal cylinder 1 rotates on the vertical pipe 2. The number of feeding pipes 3 is set to two, and the two feeding pipes 3 are respectively connected and installed on the left and right sides of the horizontal cylinder 1.

[0042] A connecting column 4 is coaxially provided in the middle of the cross cylinder 1, and coarse mesh plates 5 are provided at both ends of the connecting column 4;

[0043] Among them, the connecting column 4 and the two coarse mesh plates 5 reciprocate along the axis of the horizontal cylinder 1.

[0044] In detail, the horizontal cylinder 1 is used to hold the flowing sludge. When the horizontal cylinder 1 rotates, it drives the sludge to rotate, achieving centrifugal force on the sludge. This creates a squeezing effect on the sludge itself, squeezing out the wastewater inside. Due to the density difference between sludge and water, the sludge moves towards the end of the horizontal cylinder 1, while the wastewater moves towards the middle of the horizontal cylinder 1, thus achieving a sludge-water separation effect. The wastewater in the middle of the horizontal cylinder 1 can overflow through the vertical pipe 2. The feed pipe 3 is used to feed the flowing sludge into the horizontal cylinder 1. Since there are two feed pipes 3, installed on the left and right sides of the horizontal cylinder 1 respectively, the initial sludge entering the horizontal cylinder 1 can be... The sludge is moved away from the axis of rotation of the horizontal cylinder 1, which facilitates the rapid centrifugal state of the sludge entering the horizontal cylinder 1. The sludge is deposited at the end of the horizontal cylinder 1. The connecting column 4 and the coarse screen plate 5 inside the horizontal cylinder 1 rotate synchronously with the horizontal cylinder 1, and the connecting column 4 and the coarse screen plate 5 move back and forth inside the horizontal cylinder 1. The two coarse screen plates 5 are respectively adapted to the two ends of the horizontal cylinder 1. When the coarse screen plate 5 moves towards the end of the horizontal cylinder 1, the coarse screen plate 5 will squeeze the sludge deposited at the end of the horizontal cylinder 1, thereby providing auxiliary thrust for the dewatering of the deposited sludge, improving the sludge squeezing strength and dewatering effect. When the coarse screen plate 5 moves away from the end of the horizontal cylinder 1, the sludge inside the horizontal cylinder 1 continues to move towards the end of the horizontal cylinder 1 and deposit.

[0045] It should be noted that, due to the large amount of water in the sludge, its fluidity is relatively high. Therefore, the sludge can be pumped into the feed pipe 3 and then transported into the horizontal cylinder 1 through the feed pipe 3. The centrifugal force of the sludge can dewater the highly fluid sludge. The coarse screen plate 5 can squeeze and dewater the sludge deposited at the end of the horizontal cylinder 1, thereby realizing the squeezing of sludge in different states, realizing multi-stage dewatering of sludge, and improving the dewatering effect. The sludge in the flowing state in the horizontal cylinder 1 can pass through the coarse screen plate 5 normally and move.

[0046] By utilizing the rotation of the horizontal cylinder 1 to achieve centrifugal dewatering of sludge, the structure and equipment for providing pressurization to the sludge can be saved. Furthermore, due to the shape limitation of the horizontal cylinder 1, the sludge collection effect can be improved, increasing the compactness between sludge particles, thus facilitating easier mutual compression and enhancing the dewatering effect. Its structure and operation are simple, and the dewatering effect is excellent. Through continuous feeding via the feeding pipe 3 and continuous drainage via the vertical pipe 2, uninterrupted sludge processing can be achieved without concerns about clogging. This avoids the problems of periodic cleaning and repeated sludge discharge required in traditional methods, significantly improving work efficiency and equipment operation. The rotation of the horizontal cylinder 1 not only generates centrifugal force, which helps in the initial separation of mud and water and the coagulation of sludge, but also applies additional mechanical compression to the sludge deposited at the end of the horizontal cylinder 1 through the coarse mesh plate 5, enabling further dewatering of the coagulated sludge. This facilitates the dewatering treatment of sludge in different forms and improves the dewatering effect. In summary, this converter dust removal circulating water sludge dewatering and compression equipment, through its innovative design, solves the problems of low efficiency and frequent maintenance of traditional sludge dewatering equipment, improves the dewatering effect, and reduces operating costs. It is of great significance for improving the efficiency and environmental performance of wastewater treatment in the steel industry.

[0047] like Figure 4 As shown, a support column 6 is coaxially provided inside the vertical tube 2. The support column 6 is fixedly connected to the vertical tube 2. The end of the support column 6 extends into the horizontal tube 1. A disc 7 is provided at the end of the support column 6. An eccentric column 8 is eccentrically provided on the disc 7. A long groove 9 is horizontally provided in the middle of the connecting column 4. The length direction of the long groove 9 is perpendicular to the length direction of the connecting column 4. The eccentric column 8 is slidably installed in the long groove 9.

[0048] In detail, since the horizontal cylinder 1 rotates on the vertical pipe 2 and the support column 6 is fixedly connected to the vertical pipe 2, the support column 6 rotates relative to the horizontal cylinder 1, and the disc 7 is synchronously stationary. The horizontal cylinder 1 will drive the connecting column 4 to rotate synchronously through the coarse mesh plate 5, so that the long groove 9 rotates relative to the disc 7. Since the eccentric column 8 is eccentrically installed on the disc 7, the long groove 9 is rotating. It can achieve reciprocating motion in the horizontal cylinder 1 with the help of the eccentric column 8, thereby providing power for the movement of the connecting column 4 and the coarse mesh plate 5.

[0049] like Figure 5 As shown, the end of the horizontal cylinder 1 is provided with a discharge structure for discharging dewatered sludge. The discharge structure includes a discharge channel 10, which is connected to the horizontal cylinder 1. A side channel 11 is inclinedly provided on the side wall of the discharge channel 10. A sealing column 12 is slidably provided in the discharge channel 10. The sealing column 12 blocks the side channel 11. The sealing column 12 and the discharge channel 10 are connected by a spring 13.

[0050] A drain pipe 14 is installed on the vertical pipe 2.

[0051] In detail, the spring 13 provides elastic thrust to the sealing column 12. In its natural state, the sealing column 12 blocks the side channel 11. As the sludge deposited at the end of the horizontal cylinder 1 gradually increases, the pressure between the sludge increases and dewatering is achieved. With the help of the coarse mesh plate 5 pushing the deposited sludge, the sludge pressure is further increased. The sludge is squeezed into the discharge channel 10 and pushes the sealing column 12 to move. The spring 13 undergoes elastic deformation, thereby using the sealing column 12 to generate additional squeezing force on the sludge. The sludge in the discharge channel 10 increases and pushes the sealing column 12 away from the side channel 11. At this time, the sludge is discharged through the side channel 11, thereby realizing the discharge of the dewatered sludge.

[0052] Wastewater entering the vertical pipe 2 can overflow into the external collection device through the drain pipe 14.

[0053] like Figure 3 and Figure 6 As shown, the horizontal cylinder 1 consists of an intermediate cylinder 15 located in the middle and two side cylinders 16 installed at both ends of the intermediate cylinder 15. The vertical pipe 2 is installed on the intermediate cylinder 15, and the discharge channel 10 is installed inside the side cylinders 16.

[0054] The intermediate cylinder 15 and the side cylinder 16 are connected by a rotating ring 17, and the rotating ring 17 can rotate on the intermediate cylinder 15 and the side cylinder 16. A connecting plate 18 is fastened to the outside of the rotating ring 17. The connecting plate 18 is used to connect and fix the intermediate cylinder 15 and the side cylinder 16. A fine mesh plate 19 is provided inside the rotating ring 17. The fine mesh plate 19 is provided with a cleaning structure for backwashing a part of the rotating ring 17.

[0055] Among them, the connecting column 4 passes through the fine mesh plate 19 and slides relative to it.

[0056] In detail, the output end of the feed pipe 3 is installed on the side cylinder 16. When the feed pipe 3 feeds sludge into the side cylinder 16, the water released from the sludge can pass through the rotating ring 17 and enter the intermediate cylinder 15. The rotating ring 17 is used to filter the sewage. This can intercept the small amount of impurities remaining in the sewage after centrifugation in the side cylinder 16, thereby further improving the purity of the sewage. Since the rotating ring 17 can drive the fine screen plate 19 to rotate, when a local area of ​​the rotating ring 17 rotates to the position of the cleaning structure, the cleaning structure can backwash the local rotating ring 17, thereby avoiding impurities from clogging the rotating ring 17 and ensuring that the rotating ring 17 can be used stably for a long time.

[0057] The connecting plate 18 is used to connect and fix the intermediate cylinder 15 and the side cylinder 16, so that the side cylinder 16 will not rotate with the rotating ring 17.

[0058] like Figures 6 to 7As shown, the cleaning structure includes two baffles 20, which are distributed at an angle. The two baffles 20 and the inner wall of the intermediate cylinder 15 form a cylindrical shape, and a movable plate 21 is slidably disposed therein. A first transmission wheel 22 is driven inside the rotating ring 17. The first transmission wheel 22 is connected to the movable plate 21 by a connecting rod 23. One end of the connecting rod 23 is eccentrically mounted on the first transmission wheel 22, and the other end of the connecting rod 23 is rotatably mounted on the movable plate 21.

[0059] In detail, when the rotating ring 17 rotates, it drives the first transmission wheel 22 to rotate synchronously. The first transmission wheel 22 pulls the moving plate 21 to move back and forth through the connecting rod 23. When the moving plate 21 moves away from the fine screen plate 19, the moving plate 21 can suck the sewage in the side cylinder 16 into the cylindrical interior formed by the two baffles 20. When the moving plate 21 moves toward the fine screen plate 19, the moving plate 21 can push the water between the two baffles 20 through the fine screen plate 19, so that the water can backwash the fine screen plate 19.

[0060] As the rotating ring 17 rotates, the cleaning structure can perform a comprehensive backwashing treatment on the rotating ring 17. During installation, the baffle 20 slides in contact with the fine mesh plate 19, the baffle 20 slides in contact with the connecting column 4, and the baffle 20 is fixedly connected to the inner wall of the horizontal cylinder 1.

[0061] like Figure 7 As shown, a retainer 24 is fastened to the first transmission wheel 22, and the first transmission wheel 22 rotates on the retainer 24. The retainer 24 is fixed to the inner wall of the cross cylinder 1.

[0062] The movable plate 21 has an opening in the middle, and a sealing plate 25 is provided on the side wall of the movable plate 21 facing the fine mesh plate 19. The sealing plate 25 blocks the opening, and the sealing plate 25 is connected to the movable plate 21 by a spring piece 26.

[0063] In detail, the retainer 24 can support the first drive wheel 22, and the retainer 24 does not affect the normal operation of the connecting rod 23. When the moving plate 21 moves away from the fine mesh plate 19, due to the water pressure, the sealing plate 25 separates from the moving plate 21, and the spring 26 undergoes elastic deformation, thereby drawing the water filtered by the rotating ring 17 into the space between the two baffles 20. This makes it easy to replenish the water between the two baffles 20 and prevents the water in the side cylinder 16 from not being able to quickly enter the space between the two baffles 20 when the rotating ring 17 is blocked. When the moving plate 21 moves towards the fine mesh plate 19, the spring 26 will push the sealing plate 25 to block the opening again.

[0064] like Figure 2 and Figure 8As shown, it also includes a connecting plate 27, a column 28 and a fixed plate 29. The connecting plate 27 is fixed to the bottom of the intermediate cylinder 15, the column 28 supports the fixed plate 29, and the connecting plate 27 is rotatably mounted on the fixed plate 29. The fixed plate 29 is provided with a motor 30 and a second transmission wheel 31 for providing power to the connecting plate 27.

[0065] The bottom of the rotating ring 17 makes transmission contact with the top of the fixed plate 29.

[0066] In detail, the motor 30 is fixed at the bottom of the fixed plate 29, and the second transmission wheel 31 is rotatably mounted on the top of the fixed plate 29. The second transmission wheel 31 is connected to the connecting plate 27. The motor 30 provides power to the second transmission wheel 31, thereby driving the horizontal cylinder 1 to rotate through the connecting plate 27. The horizontal cylinder 1 will drive the rotating ring 17 to roll on the fixed plate 29, thereby causing the rotating ring 17 and the fine mesh plate 19 to rotate.

[0067] like Figure 8 As shown, a chamber 32 is provided inside the column 28, and a feeding pipe 33 is connected to the chamber 32. Multiple guide ports 34 connected to the chamber 32 are provided on the outer wall of the column 28. A grooved plate 35 is fastened to the outside of the multiple guide ports 34. The grooved plate 35 is connected to the chamber 32 through the guide ports 34 and rotates on the column 28. The feeding pipe 3 is connected to the grooved plate 35.

[0068] In detail, sludge can enter the chamber 32 through the feeding pipe 33 and be fed into the feeding pipe 3 through the guide port 34 and the grooving plate 35. When the horizontal cylinder 1 rotates, it can drive the feeding pipe 3 and the grooving plate 35 to rotate synchronously, and the grooving plate 35 and the chamber 32 remain in communication.

[0069] like Figure 1 As shown, it also includes an outer casing 36 located outside the horizontal cylinder 1, a vertical pipe 2 passing through the outer casing 36 and fixedly connected, a drain pipe 14 located outside the outer casing 36, a column 28 with its bottom fixed to the outer casing 36, and a feeding pipe 33 passing through the outer casing 36 and extending out.

[0070] The bottom surface of the outer casing 36 is inclined, and a discharge port is provided on the outer casing 36. The sludge discharged from the side channel 11 falls onto the inclined surface at the bottom of the outer casing 36 and is discharged through the discharge port.

[0071] In detail, the outer casing 36 can support the horizontal cylinder 1 so that the horizontal cylinder 1 can move smoothly inside the outer casing 36. The sludge discharged from the side channel 11 falls to the bottom of the outer casing 36 and moves along the bottom slope of the outer casing 36 towards the discharge port. The sludge is automatically discharged through the discharge port.

[0072] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
