Description

Technical Field

[0001] This invention relates to the field of sludge treatment technology, specifically to an automatic sludge conditioning device. Background Technology

[0002] River and lake silt is formed by the long-term deposition of pollutants in water bodies and is rich in organic matter, nitrogen, phosphorus, and other nutrients. During water flow, pollutants from the silt are released into the water, causing eutrophication. Therefore, dredging is an important means of controlling river and lake pollution. The dredged silt has a high water content and is rich in pollutants; conventional disposal methods can easily cause secondary pollution, necessitating safe landfilling. Currently, my country's landfills are nearing saturation, and there are insufficient sites to accommodate the silt; therefore, silt treatment is necessary.

[0003] Utility model patent CN212076780U discloses an automated sludge conditioning device, including a base. A box is fixedly connected to the top of the base. Fixed plates are fixedly connected to both sides of the inner wall of the box. Baffles are movably connected to opposite sides of the two fixed plates. Electric telescopic rods are movably connected to both sides of the inner wall of the box and to the bottom of the two fixed plates. The other ends of the two electric telescopic rods are movably connected to the bottom of the two baffles, respectively. Guide plates are fixedly connected to the top of the two fixed plates. A support frame is fixedly connected to the right side of the box. A loading box is fixedly connected to the top of the support frame. A discharge chute is provided at the bottom of the loading box. This utility model realizes automatic addition of chemicals during conditioning, eliminating the need for manual periodic addition of chemicals, and facilitates cleaning of the stirring rod and the inside of the box, reducing subsequent maintenance costs.

[0004] The aforementioned device uses a micro motor to rotate a rotating rod, which in turn moves a limiting plate into the interior of a sleeve, opening the through-hole on the sleeve and allowing chemical agents to be delivered into the housing through a discharge chute. This achieves automatic agent addition. However, the required amount of adjusting agent will increase or decrease proportionally depending on the amount of sludge inside, and the corresponding stirring rate must also change synchronously to ensure consistent time intervals between subsequent agent additions. If the next agent is added before the previous one is fully mixed, it can easily cause a direct reaction between the two agents, affecting the sludge conditioning effect. Furthermore, novice operators may easily make mistakes in the order of agent addition, resulting in poor sludge conditioning and wasted resources. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) This invention, through the setting of a feeding cylinder, three discharge ports, a sliding plate, three discharge holes, three conical plugs, six return springs, a transmission belt, a feeding rack, a missing gear, a transmission shaft, and three piston plates, realizes the sequential addition of conditioning agents according to the order of addition, avoiding resource loss caused by novice operators accidentally making a mistake in the order of adding conditioning agents. Furthermore, by using different sizes of the feeding cylinder, it can adapt to different addition ratios of conditioning agents, and simultaneously add conditioning agents proportionally according to the amount of sludge, without the need for manual measurement and intervention. Moreover, the addition interval of conditioning agents is set according to the number of stirring cycles of the stirring column, thereby achieving adaptive adjustment of the interval time for adding conditioning agents according to the mixing rate, ensuring that the previous conditioning agent is fully mixed before adding the next conditioning agent, without the need for manual operation, which is convenient and fast.

[0016] (2) By setting up a first bevel gear, a second friction wheel, a first telescopic rod, an adjusting motor, a U-shaped mounting bracket and a second telescopic rod, the present invention achieves faster synchronous stirring speed when the amount of sludge is larger, accelerates the mixing rate between the conditioner and the sludge, avoids the situation where the previous conditioner has not been fully mixed when the next conditioner is added, and avoids the situation where the two conditioners react preferentially and affect the sludge conditioning effect.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-6 An embodiment of the present invention provides an automatic sludge conditioning device, comprising a cylinder 1, a cylinder cover 8 at the top of the cylinder 1, a protective shell 14 fixedly mounted on the top of the cylinder cover 8, a stirring column 3 rotatably mounted in the middle of the cylinder cover 8, a plurality of stirring rods 2 fixedly mounted on the stirring column 3, a speed adjustment mechanism 6 mounted on the top of the stirring shaft, a hollow ring 4 slidably mounted on the inner wall of the cylinder 1, a stroke shortening mechanism 5 mounted on the top of the ring 4, an L-shaped connecting rod 10 fixedly mounted on the top of the stroke shortening mechanism 5, a T-shaped rod 11 fixedly mounted at the end of the L-shaped connecting rod 10, a feeding mechanism 7 mounted at the end of the T-shaped rod 11, an installation block 13 fixedly mounted on the inner wall of the protective shell 14, and three liquid storage tanks 9 fixedly mounted on the top of the inner side of the protective shell 14. First, the sludge is poured into the cylinder 1. At this time, the ring 4, due to its hollow and lightweight plastic material, floats to the surface of the sludge liquid. Simultaneously, the ring 4 moves upward, causing the stroke shortening mechanism 5 to work. The stroke shortening mechanism 5 drives the L-shaped connecting rod 10 to move. The movement of the L-shaped connecting rod 10 drives the T-shaped rod 11 to move synchronously. The movement of the T-shaped rod 11 drives the speed adjustment mechanism 6 to increase the speed of the stirring column 3. Thus, as the amount of sludge increases, the mixing speed of the stirring rod 2 increases synchronously. At the same time, the movement of the T-shaped rod 11 drives the feeding mechanism 7 to work, causing the amount of conditioning agent inside the feeding mechanism 7 to increase synchronously. While the stirring column 3 rotates and drives the stirring rod 2 to rotate, the feeding mechanism 7 adds the conditioning agent in sequence, and the feeding time decreases synchronously as the mixing speed increases. This ensures that the conditioning agent is mixed evenly and maximizes the reduction of the feeding time interval, thereby improving the sludge conditioning efficiency of the device.

[0027] Specifically, the stroke shortening mechanism 5 includes two first gears 51, a mounting sleeve 52, two second gears 53, a U-shaped rack 54, and a double-sided rack 55. The mounting sleeve 52 is fixedly installed on the inner wall of the cylinder 1. The two first gears 51 are rotatably installed inside the mounting sleeve 52. The two second gears 53 are respectively fixedly installed on the two first gears 51. The end of the double-sided rack 55 is fixedly installed on the top of the ring 4. The U-shaped rack 54 is fixedly installed on the end of the L-shaped connecting rod 10. By moving the ring 4 upward, the double-sided rack 55 moves synchronously. The movement of the double-sided rack 55 drives the first gears 51 to rotate. The rotation of the first gears 51 drives the second gears 53 to rotate. The rotation of the second gears 53 drives the U-shaped rack 54 to move synchronously. The movement of the U-shaped rack 54 drives the L-shaped connecting rod 10 to move synchronously. This achieves a proportional shortening of the moving distance of the ring 4, thereby reducing the area occupied by the device above the cylinder 1 and meeting the requirement of a relatively small proportion of conditioner and sludge to be added.

[0028] Specifically, both first gears 51 mesh with double-sided racks 55, and the two second gears 53 mesh with U-shaped racks 54 respectively.

[0029] Specifically, the speed adjustment mechanism 6 includes a first bevel gear 61, a second friction wheel 62, a first telescopic rod 63, an adjustment motor 64, a U-shaped mounting bracket 65, and a second telescopic rod 66. The U-shaped mounting bracket 65 is fixedly mounted on the side wall of the mounting block 13, the adjustment motor 64 is fixedly mounted on the bottom of the mounting block 13, one end of the telescopic rod is fixedly mounted on the end of the output shaft of the adjustment motor 64, the friction wheel is fixedly mounted on the other end of the telescopic rod, the telescopic rod is slidably engaged with the U-shaped mounting bracket 65, the first bevel gear 61 is fixedly mounted on the top of the stirring column 3, and the two ends of the second telescopic rod 66 are respectively fixedly mounted on the side wall of the L-shaped connecting rod 10 and the end of the first telescopic rod 63. The L-shaped connecting rod 10 moves synchronously, driving the second telescopic rod 66 to move as well. The movement of the second telescopic rod 66 causes the second friction wheel 62 to move upwards. Simultaneously, the upward movement of the second friction wheel 62 causes the first telescopic rod 63 to retract, ensuring that the second friction wheel 62 is always engaged with the conical surface of the first bevel gear 61. After the second friction wheel 62 has moved, the output shaft of the adjusting motor 64 rotates, driving the first telescopic rod 63 to rotate. The rotation of the first telescopic rod 63 then drives the second friction wheel 62 to rotate, which in turn drives the first bevel gear 61 to rotate. The rotation of the first bevel gear 61 then drives the stirring column 3 to rotate. This achieves faster synchronous stirring speeds even with larger sludge volumes, accelerating the mixing rate between the conditioner and sludge. It prevents the addition of subsequent conditioners before the previous ones are fully mixed, avoiding situations where two conditioners react preferentially and affect the sludge conditioning effect. No manual monitoring or adjustment is required, reducing the labor intensity of workers and facilitating widespread adoption.

[0030] Specifically, the first bevel gear 61 meshes with the friction wheel for transmission, and the tilt angle of the first telescopic rod 63 is consistent with the tilt angle of the conical surface of the first bevel gear 61.

[0031] Specifically, the feeding mechanism 7 includes three feeding cylinders 71, three top covers 72, three hollow rods 73, three discharge ports 74, a sliding plate 75, three discharge holes 76, three conical plugs 77, six return springs 78, a transmission belt 79, a feeding rack 710, a missing gear 711, a transmission shaft 712, six connecting columns 713, and three piston plates 714. The transmission belt 79 is sleeved on the side wall of the stirring column 3. The transmission shaft 712 is rotatably disposed inside the cylinder cover 8. The transmission shaft 712 is in transmission cooperation with the transmission belt 79. The missing gear 711 is fixedly disposed on the top of the transmission shaft 712. The feeding rack 710 is slidably disposed on the top of the cylinder cover 8. The sliding plate 75 is fixedly disposed on the side of the feeding rack 710. The discharge port 74 is disposed on the sliding plate 75. The three hollow rods 73 are respectively fixedly disposed on the side walls of the three liquid storage tanks 9. The three feeding cylinders 71 are respectively fixedly disposed on the ends of the three hollow rods 73. The three top covers 72 are respectively fixedly disposed on the tops of the three feeding cylinders 71. The three discharge ports 74 are respectively disposed on the bottom of the sliding plate 75. The six connecting columns 713 are fixedly disposed on the ends of the T-shaped rods 11. The three piston plates 714 are respectively fixedly disposed on the bottoms of the six connecting columns 713. The three discharge holes 76 are respectively disposed at the center of the three piston plates 714. The six return springs 78 are respectively disposed on the side walls of the three discharge holes 76. The three conical plugs 77 are respectively fixedly disposed on the ends of the six return springs 78. The upward movement of the L-shaped connecting rod 10 causes the T-shaped rod 11 to move upward, which in turn causes the connecting column 713 to move upward. The upward movement of the connecting column 713 then causes the piston plate 714 to move upward. This upward movement of the piston plate 714 increases the pressure above the feed cylinder 71, stretching the return spring 78. The conditioning agent flows from the outlet 76 to below the piston plate 714 and is then driven by the rotation of the stirring column 3, which in turn drives the transmission belt 79. The transmission belt 79 drives the transmission shaft 712 and the missing gear 711 to rotate synchronously. The rotation of the missing gear 711 causes the feeding rack 710 to move synchronously. The movement of the feeding rack 710 causes the sliding plate 75 to move, which in turn causes the outlet... The feed inlet 74 is aligned with the bottom of the corresponding feed cylinder 71, allowing the corresponding conditioning agents to flow into the cylinder 1 sequentially. This ensures that the conditioning agents are added in the correct order, preventing novice operators from accidentally adding the wrong agents and causing resource loss. Furthermore, the varying sizes of the feed cylinders 71 accommodate different conditioning agent addition ratios, and the conditioning agents are added proportionally according to the amount of sludge, eliminating the need for manual measurement. The addition interval of the conditioning agents is set based on the number of stirring cycles of the mixing column 3, thus achieving adaptive adjustment of the addition interval according to the mixing rate. This ensures that the previous conditioning agent is fully mixed before adding the next one, making it convenient and quick without manual operation.

[0032] Specifically, the bottom areas of the three feeding cylinders 71 gradually increase, and the dimensions of the three discharge ports 74 are respectively adapted to the bottom areas of the three feeding cylinders 71, and the three piston plates 714 are respectively located and slide inside the three feeding cylinders 71.

[0033] Specifically, the feeding rack 710 meshes with the missing gear 711.

[0034] Working principle: First, sludge is poured into the cylinder 1. At this time, the ring 4, due to its hollow lightweight plastic material, floats and eventually drifts to the surface of the sludge. Simultaneously, the upward movement of the ring 4 drives the double-sided rack 55 to move synchronously. The movement of the double-sided rack 55 drives the first gear 51 to rotate, which in turn drives the second gear 53 to rotate. The rotation of the second gear 53 drives the U-shaped rack 54 to move synchronously, which in turn drives the L-shaped connecting rod 10 to move synchronously. The movement of the L-shaped connecting rod 10 drives the T-shaped rod 11 to move synchronously, which in turn drives the second telescopic rod 66 to move synchronously. The movement of the second telescopic rod 66 drives the second friction wheel 62 to move upward. Simultaneously, the upward movement of the second friction wheel 62 drives the first telescopic rod 63 to retract, ensuring that the second friction wheel 62 is always meshed with the conical surface of the first bevel gear 61. After the second friction wheel 62 has finished moving, the output shaft of the adjusting motor 64 rotates, driving the first telescopic rod 63 to rotate. The rotation of the first telescopic rod 63 drives the second friction wheel 62 to rotate. The second friction wheel 62 and the rotating... The rotation of the first bevel gear 61 causes the stirring column 3 to rotate. This rotation, via the upward movement of the L-shaped connecting rod 10, causes the T-shaped rod 11 to move upward. The upward movement of the T-shaped rod 11 then causes the connecting column 713 to move upward, which in turn causes the piston plate 714 to move upward. This upward movement of the piston plate 714 increases the pressure above the feed cylinder 71, stretching the return spring 78. The conditioning agent then flows from the discharge hole 76 to below the piston plate 714 and is further affected by the rotation of the stirring column 3. The drive belt 79 drives the drive shaft 712 and the missing gear 711 to rotate synchronously. The rotation of the missing gear 711 drives the feeding rack 710 to move synchronously. The movement of the feeding rack 710 drives the sliding plate 75 to move. The movement of the sliding plate 75 causes the discharge port 74 to be aligned with the bottom of the corresponding feeding cylinder 71 in sequence, so that the corresponding conditioning agent flows into the cylinder 1 in sequence. This not only ensures the uniform mixing of the conditioning agent, but also maximizes the shortening of the feeding time interval, thereby improving the sludge conditioning efficiency of the device.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
