A device for homogenizing and adding activated carbon slurry

Abstract

This invention discloses an activated carbon slurry anti-sedimentation homogenization dosing device, which relates to the field of water treatment agent dosing technology. This activated carbon slurry anti-sedimentation homogenization dosing device adopts a three-stage synergistic homogenization structure: bottom aeration disturbance, planetary stirring and shearing, and axial forced circulation. Microbubbles released from the bottom spiral aeration pipe lift particles at the bottom of the cylinder from the source, breaking up agglomerates. The planetary stirring structure achieves radial full-range shearing and mixing to eliminate local concentration differences. The axial spiral conveying structure forcibly completes the circulation and exchange of the upper and lower slurry layers, breaking the vertical concentration gradient. The three elements work together to form a three-dimensional homogenization effect, which can maintain the uniform suspension state of fine-diameter activated carbon particles for a long time, avoiding the problems of material accumulation and agglomeration at the bottom of the cylinder and concentration stratification (thinner at the top and thicker at the bottom). This provides a stable slurry foundation for quantitative dosing, while improving the effective utilization rate of activated carbon and the subsequent process treatment effect.

Description

Technical Field

[0001] This invention relates to the field of water treatment agent dosing technology, specifically to an activated carbon slurry anti-settling and homogenization dosing device. Background Technology

[0002] The activated carbon slurry anti-sedimentation homogenization dosing device is a piece of equipment used in wet powdered activated carbon dosing processes. It mixes powdered activated carbon with process water in a set ratio to prepare a carbon slurry with uniform concentration. Through multiple technical means such as mechanical stirring and fluid disturbance, it inhibits the sedimentation and stratification of activated carbon particles, ensuring that the slurry concentration is uniform and stable throughout the process. The device accurately and continuously adds the carbon slurry to the target water body through a metering and conveying unit. This device is widely used in scenarios such as emergency deodorization and taste removal in waterworks, deep treatment of industrial wastewater, and purification of slightly polluted water sources.

[0003] After the activated carbon slurry is mixed, it is manually added to the designated position when needed. The operator adds the activated carbon slurry once per hour according to the process requirements. The amount added each time needs to be weighed and then manually added to the solution tank. This needs to be done 24 times a day, which leads to low efficiency and high labor intensity for the operators. In addition, human error may cause the activated carbon to be added late or forgotten, which will affect the stability of the process system. Furthermore, the slurry placed inside the mixing drum has a settling problem, resulting in a situation where the upper layer of the slurry has a low concentration and the lower layer has a high concentration.

[0004] Therefore, it is necessary to design a system that can be filled with water and mixed with activated carbon to ensure thorough and uniform mixing, thereby improving the stability of the slurry concentration and solving the above problems. Summary of the Invention

This mode can support continuous operation without the need for operators to manually replenish the slurry every hour, significantly reducing the labor intensity and operation and maintenance costs. At the same time, through the precise control of the dosing cycle and the amount of each dosing through the electronic control program, it completely avoids problems such as overtime dosing, missed dosing, and dosing deviation caused by human factors, ensuring the continuous stability of water quality and treatment effect of the process system and improving the overall operational reliability of the system.

[0026] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0027] Please see Figures 1-15 This invention provides an activated carbon slurry anti-settling homogenization dosing device, including a mixing cylinder 1 and a base installed at the bottom of the mixing cylinder 1. The device is characterized in that: a diaphragm pump 2 is installed on the side wall of the mixing cylinder 1 through an output mechanism 3; a horizontal plate 8 is installed on the top of the mixing cylinder 1 through a locking mechanism 5; a sealing cover 9 is installed on the bottom wall of the horizontal plate 8 through an angle iron; the outer wall of the sealing cover 9 is fitted with the inner wall of the mixing cylinder 1 to form a top seal; a driving mechanism 6 is installed on the top of the horizontal plate 8; and an aeration mechanism 4 is installed inside the mixing cylinder 1. The aeration mechanism 4 includes a mounting frame 41 placed at the bottom of the mixing cylinder 1. A spiral aeration pipe 45 is installed on the top of the mounting frame 41. Several aeration micro-holes are evenly opened on the top of the spiral aeration pipe 45 along the spiral direction to aerate a large number of micro-bubbles into the slurry to improve the mixing uniformity. A conveying pipe 13 is fixedly installed on the top of the drive mechanism 6. The bottom and top ends of the conveying pipe 13 are connected to the inside of the mixing cylinder 1. A spiral conveying rod 14 is fixedly installed on the bottom of the drive mechanism 6 to cooperate with the conveying pipe 13 to convey the upper layer of slurry to the lower layer of slurry. A mounting sleeve 10 is fixedly installed on the outer wall of the drive mechanism 6. Several stirring rods 11 are evenly installed on the outer wall of the mounting sleeve 10. Stirring blades 12 are fixedly installed on the outer ends of the stirring rods 11 located on the same mounting axis.

[0028] In this implementation scheme, a three-level synergistic anti-sedimentation homogenization system is constructed by the aeration mechanism 4, the screw conveyor rod 14 in cooperation with the conveying pipe 13, the stirring rod 11 and the stirring blades 12, which simultaneously achieves multiple effects of bottom aeration lifting, forced circulation of upper and lower layers of slurry, and radial full-area stirring, effectively solves the problems that activated carbon particles are prone to sedimentation and agglomeration and the slurry is thin in the upper part and dense in the lower part under the traditional single stirring mode, significantly improves the mixing uniformity and long-term suspension stability of the slurry, and provides a reliable concentration basis for subsequent precise dosing.

[0029] Specifically, a counterweight 44 is arranged inside the mounting frame 41, the air inlet end of the spiral aeration pipe 45 is communicated with and mounted with an air supply pipe 43, the air supply pipe 43 is arranged in a "Ω"-shaped distribution, a copper ball valve 42 is mounted on the outer wall of the air supply pipe 43, an avoidance groove is opened at the top of the sealing cover 9 and at a position corresponding to the air supply pipe 43, for accommodating the arrangement position of the air supply pipe 43, a plurality of elastic clips 46 are uniformly mounted on the inner wall and outer wall of the mixing cylinder 1 at positions corresponding to the arrangement position of the air supply pipe 43, and an access groove 461 is opened on one side of the elastic clip 46 corresponding to the air supply pipe 43.

[0030] In this implementation scheme, the counterweight 44 can offset the reverse buoyancy generated by the rising aeration airflow through its own weight, ensure that the position of the spiral aeration pipe 45 at the bottom of the mixing cylinder 1 is constant, and avoid the occurrence of disturbance dead zones caused by the deviation of aeration points; The elastic clip 46 cooperates with the access groove 461 to realize the press-type quick installation and fixation of the air supply pipe 43, the pipeline arrangement is regular, and the disassembly and assembly are convenient; The avoidance groove design of the sealing cover 9 can avoid squeezing and damaging the air supply pipeline during top assembly, and the overall structure gives consideration to both operation stability and maintenance convenience.

[0031] Specifically, the driving mechanism 6 includes a mounting box 62 fixedly mounted on the top of the horizontal plate 8, a servo motor 61 is fixedly mounted on the top of the mounting box 62, a driving gear 63 is fixedly mounted on the power shaft of the servo motor 61 through penetrating the mounting box 62, a transmission shaft 65 is rotatably mounted on the inner wall of the mounting box 62, a driven gear 64 is fixedly mounted on the outer wall of the transmission shaft 65, and the driven gear 64 is meshed with the driving gear 63.

[0032] In this implementation scheme, the servo motor 61 is used as the power source, which can accurately regulate the transmission speed and adapt to the homogenization working condition requirements of slurries with different activated carbon concentrations and different viscosities; The meshing transmission of the driving gear 63 and the driven gear 64 has stable torque transmission and high transmission precision, and can stably drive the lower actuator to operate; The mounting box 62 can form dust-proof and splash-proof protection for the internal gear transmission assembly, effectively prolonging the service life of the transmission components.

[0033] Specifically, the drive shaft 66 is fixedly installed at the bottom end of the drive shaft 65 through the mounting box 62 and the sealing cover 9 in sequence via bearings. The bottom of the sealing cover 9 is fixedly installed with a mounting ring 67. The inner wall of the mounting ring 67 is fixedly installed with a transmission gear ring 68. The outer wall of the mounting ring 67 is rotatably installed with a steering wheel 69. The center of the inner wall of the steering wheel 69 is fixedly connected to the bottom end of the drive shaft 66. The bottom wall of the steering wheel 69 is fixedly connected to the top end of the screw conveyor rod 14.

[0034] In this embodiment, the drive shaft 66 drives the steering wheel 69 to revolve around the central axis, which can synchronously drive the spiral conveyor rod 14 and the lower stirring assembly to make circular motion, greatly expanding the radial coverage of the homogenization operation; The fixed transmission gear ring 68 provides a fixed meshing reference for the lower planetary transmission, achieving a compact and highly integrated self-rotation drive structure for the stirring assembly without the need for an additional self-rotation power source.

[0035] Specifically, a steering shaft 610 is rotatably mounted on one side of the bottom wall of the steering wheel 69. The bottom of the outer wall of the steering shaft 610 is fixedly connected to the inner wall of the mounting sleeve 10. The top of the steering shaft 610 is fixedly mounted with a transmission gear 611 through the steering wheel 69 via a bearing. The transmission gear 611 meshes with the transmission gear ring 68. A U-shaped frame 612 is fixedly mounted inside the sealing cover 9. The inner wall of the U-shaped frame 612 is fixed to the bottom end of the delivery pipe 13.

[0036] In this embodiment, by means of the meshing of the transmission gear 611 and the transmission gear ring 68, the steering shaft 610 can be driven to rotate simultaneously while the steering wheel 69 drives the steering shaft 610 to revolve, thereby driving the stirring rod 11 and the stirring blade 12 to achieve planetary stirring motion. The stirring trajectory covers the entire area without dead angles, and the effect of breaking up carbon particle agglomerates is better than that of traditional fixed-axis stirring. The U-shaped frame 612 provides stable support and limits to the conveying pipe 13, preventing it from shaking due to disturbances in the slurry flow field and ensuring continuous and stable axial circulation conveying.

[0037] Specifically, the locking mechanism 5 includes positioning frames 51 fixedly installed on both sides of the outer wall of the mixing drum 1. The top of each positioning frame 51 is provided with a positioning groove 514. The top of the positioning frame 51 is attached to the bottom wall of the horizontal plate 8. Positioning blocks 52 are installed on both sides of the bottom wall of the horizontal plate 8 at positions corresponding to the positioning grooves 514. The outer walls of the positioning blocks 52 are respectively attached to the inner walls of the corresponding positioning grooves 514.

[0038] In this embodiment, the insertion and engagement structure of positioning block 52 and positioning groove 514 is adopted, which can quickly and initially align the horizontal plate 8 and the top drive assembly, reducing the difficulty of assembly alignment. At the same time, it can limit the horizontal displacement of the horizontal plate 8, prevent the top assembly from moving laterally during the operation of the device, and ensure the coaxiality and operational stability of the transmission structure.

[0039] Specifically, positioning shafts 511 are fixedly installed on the bottom wall of the horizontal plate 8 and at the front and rear of the positioning block 52. Positioning holes 512 are opened on the top wall of the positioning frame 51 at the position corresponding to the positioning shafts 511. The inner wall of the positioning hole 512 is inserted and aligned with the outer wall of the corresponding positioning shaft 511. Locking grooves 53 are opened on the outer wall of the positioning block 52. Passing grooves 513 are opened on the side wall of the positioning frame 51 for communicating with the positioning grooves 514.

[0040] In this embodiment, the insertion and engagement of the positioning shaft 511 and the positioning hole 512 can achieve circumferential pre-positioning, effectively resist the rotational torque generated during the stirring operation, and prevent the horizontal plate 8 from rotating and shifting circumferentially. The connection between the locking groove 53 and the through groove 513 provides ample space for the extension and retraction of the locking component, ensuring smooth execution of automatic locking and unlocking actions.

[0041] Specifically, a fixing frame 58 is fixedly installed on the outer wall of the positioning frame 51. The inner wall of the fixing frame 58 is connected to the through groove 513 and the positioning groove 514. A guide shaft 510 is fixedly installed on the inner wall of the fixing frame 58. A slider 57 is slidably installed on the inner wall of the fixing frame 58. A locking block 54 is fixedly installed on the side of the slider 57 near the locking groove 53. Guide angles 55 are provided at the top and bottom of the locking block 54. The outer wall of the locking block 54 fits against the inner wall of the locking groove 53.

[0042] In this embodiment, the guide angle 55 at the end of the locking block 54 can convert the vertical downward pressure of the positioning block 52 into the lateral retraction thrust of the locking block 54. The locking block 54 can automatically retract and avoid the block simply by pressing down the horizontal plate 8, achieving the assembly effect of "locking upon pressing down" and greatly improving the installation efficiency of the top assembly.

[0043] Specifically, the inner wall of the slider 57 is provided with a guide groove 56, the inner wall of the guide groove 56 is slidably connected to the outer wall of the guide shaft 510, and the inner wall of the slider 57 and the fixing frame 58 are fitted with abutment springs 59, one end of the abutment spring 59 is fixedly connected to the side wall of the slider 57, and the other end of the abutment spring 59 is fixedly connected to the fixing frame 58.

[0044] In this embodiment, the sliding fit between the guide shaft 510 and the guide groove 56 can radially guide the extension and retraction of the slider 57, thus preventing the locking block 54 from skewing or jamming during the extension and retraction process. The abutment spring 59 provides a continuous and stable elastic abutment force. When the locking block 54 is aligned with the locking groove 53, it pushes the locking block 54 into the locking groove 53 to complete the locking, ensuring that the locking state is firm and reliable. When disassembling, simply pull the slider 57 outward to compress the spring to unlock, making the disassembly and assembly operation simple and efficient.

[0045] Specifically, the output mechanism 3 includes an air outlet 34 connected to the side wall of the diaphragm pump 2, a liquid outlet pipe 35 connected to the top of the diaphragm pump 2, an air inlet pipe 32 connected to the side of the diaphragm pump 2, a solenoid valve 33 installed on the outer wall of the air inlet pipe 32, an inlet pipe 31 connected to the bottom of the diaphragm pump 2, and the left end of the inlet pipe 31 passes through the mixing cylinder 1 through a leak-proof rubber sleeve and extends to the bottom of the inner cavity. A transparent observation window 7 with scale lines is installed on the side wall of the mixing cylinder 1.

[0046] In this implementation scheme, the intermittent start and stop of the diaphragm pump 2 is controlled by the solenoid valve 33, which can realize the automated timed and quantitative addition of activated carbon slurry, completely replacing the traditional manual weighing and sequential manual addition operation mode. It can support 24-hour continuous operation, greatly reduce the labor intensity of operators, and completely avoid problems such as missed addition, overtime addition, and addition deviation caused by human factors, ensuring the operational stability of the process system and the consistency of treatment effect. The graduated transparent observation window 7 allows for real-time monitoring of the slurry level and mixing status inside the cylinder, facilitating timely adjustment of operating parameters by maintenance personnel and improving the convenience of daily maintenance.

[0047] Working principle: The diaphragm pump 2, solenoid valve 33, and servo motor 61 of this device are electrically connected to an external power source through a standardized wiring layout, providing a stable and controllable power source for the entire process of the device. The signal input terminals of the components are all connected one-to-one with the signal output terminals of the external controller, and the signal feedback terminals are connected to the signal input terminals of the controller, which can realize the real-time transmission and execution of commands, providing core control guarantee for the automated homogenization and quantitative dosing of the device. The following is a detailed description of the specific working principle and technical effects. The bottom-embedded aeration structure design is adopted. During installation, the mounting frame 41, which integrates the counterweight 44 and the spiral aeration pipe 45, is first placed into the bottom of the mixing cylinder 1, so that the bottom of the mounting frame 41 is in contact with the inner bottom wall of the mixing cylinder 1. The counterweight 44 counteracts the reverse buoyancy generated by the rising airflow during aeration, so that the mounting frame 41 and the spiral aeration pipe 45 are stably fixed at the bottom of the mixing cylinder 1 and will not be displaced by airflow disturbance, thus ensuring the accuracy of the aeration point and the long-term operational stability. The air supply pipe 43 is then quickly assembled: the movable air supply pipe 43 is pressed through the entry groove 461 at the top of the elastic buckle 46, and finally snapped into the groove of the elastic buckle 46 to complete the regular positioning of the air supply pipe 43. During the pressing of the pipe, the entry groove 461 is elastically expanded by the pressure of the pipe, providing clearance for the installation of the air supply pipe 43, so that the air supply pipe 43 can be smoothly snapped into the corresponding elastic buckle 46; after the snapping is completed, the entry groove 461 elastically resets to prevent the air supply pipe 43 from falling out on its own, which combines convenient installation and reliable fixation. After the pipe is assembled, the end of the air supply pipe 43 is connected to the external blower to provide an air source path for subsequent aeration disturbance. Slurry proportioning and feeding: Activated carbon and water are added into the mixing cylinder 1 according to the process ratio: First, sufficient clean water is injected into the mixing cylinder 1. The water level is observed in real time through the observation window 7 set in the cylinder wall to accurately control the amount of water added. Then, the corresponding mass of activated carbon is added into the mixing cylinder 1 according to the proportion to complete the initial slurry preparation. The visualization design of the observation window 7 can replace manual opening of the lid for measurement, improve the proportioning efficiency and accuracy, and avoid slurry splashing and loss during the feeding process. Before placing the movable horizontal plate 8, which integrates the sealing cover 9, drive mechanism 6, and locking mechanism 5, onto the top of the mixing cylinder 1, adjust the angle of the horizontal plate 8 so that the pre-set clearance groove on the outer wall of the sealing cover 9 is aligned with the position of the air supply pipe 43 to avoid squeezing and damaging the air supply pipe 43 during the pressing process. During the downward pressing of the horizontal plate 8, the positioning shaft 511 and the positioning block 52 are simultaneously driven to move downward: the positioning shaft 511 is first inserted into the positioning hole 512 at the top of the positioning frame 51 to complete the installation and positioning, which can offset the rotational torque generated by the subsequent drive mechanism 6 during operation and prevent the horizontal plate 8 from shifting circumferentially. At the same time, the positioning block 52 is inserted into the positioning groove 514, and its bottom end first contacts the guide angle 55 on the outer wall of the locking block 54. Under the action of the downward pressure, the guide angle 55 converts the vertical downward pressure into a horizontal thrust, which drives the locking block 54 and the slider 57 to slide and retract along the through groove 513 into the fixed frame 58, providing clearance space for the downward movement of the positioning block 52. During the sliding process, the slider 57 compresses the abutment spring 59 simultaneously, and the outer wall of the guide shaft 510 and the inner wall of the guide groove 56 always slide and fit together, which radially limits the movement of the slider 57 to prevent the locking block 54 from getting stuck. When the positioning block 52 is inserted into the positioning groove 514 and the bottom wall of the horizontal plate 8 is attached to the top of the positioning frame 51, the position of the locking block 54 is aligned with the locking groove 53 on the side wall of the positioning block 52. At this time, the abutment spring 59 releases elastic potential energy to push the slider 57 and the locking block 54 to slide in opposite directions, so that the locking block 54 is inserted into the locking groove 53, automatically completing the locking limit. The sealing cover 9 is embedded in the top opening of the mixing cylinder 1 to complete the sealing of the cylinder opening, preventing the slurry from splashing and overflowing during the mixing and aeration process. Automatic locking can be completed by pressing down, which greatly improves the disassembly and assembly efficiency of the top assembly. At the same time, the locking and pre-positioning structure can fully resist the mixing torque and ensure the structural stability during operation. A three-stage synergistic homogenization system, consisting of bottom aeration disturbance, planetary stirring shearing, and axial circulation homogenization, is adopted to comprehensively suppress particle sedimentation and ensure uniform slurry concentration throughout the cylinder. The specific operation process is as follows: Bottom aeration disturbance inhibits sedimentation at the source: Opening the copper ball valve 42 and starting the external blower, compressed air is delivered to the spiral aeration pipe 45 through the air supply pipe 43, and finally discharged outward through the dense micropores of the aeration pipe wall to form a large number of microbubbles. The microbubbles rise slowly in the slurry in a smoke-like manner. With the lifting effect of the gas-liquid two-phase flow, they continuously lift and shear the activated carbon particles at the bottom of the mixing cylinder 1. On the one hand, this breaks the gravity sedimentation balance of the 200-mesh fine particles and prevents the particles from accumulating and agglomerating at the bottom of the cylinder. On the other hand, the interfacial shear force of the bubbles disperses the activated carbon agglomerates, so that the carbon particles are evenly dispersed in the water. This alleviates the concentration stratification problem of being less concentrated at the top and more concentrated at the bottom from the sedimentation source. The spiral pipeline arrangement can cover the entire bottom of the cylinder with the aeration range, ensuring the overall disturbance effect.

[0048] Planetary mixing and shearing for comprehensive dispersion and mixing: The servo motor 61 on the top of the mounting box 62 drives the drive gear 63 to rotate at a constant speed. Through gear meshing, the driven gear 64 rotates synchronously, which in turn drives the transmission shaft 65 and the drive shaft 66 to rotate slowly. When the drive shaft 66 rotates, it drives the steering wheel 69 to make a circular revolution along the outer wall of the mounting ring 67. While the steering wheel 69 is revolving, the transmission gear 611 installed at its end is engaged with the fixed transmission gear ring 68. Therefore, the transmission gear 611 rotates on its own axis while revolving with the steering wheel 69, which in turn drives the steering shaft 610 to achieve a planetary motion of revolution and rotation. The steering shaft 610 drives the mounting sleeve 10, stirring rod 11 and stirring blade 12 to perform planetary stirring motion synchronously. Compared with traditional fixed-axis stirring, the stirring trajectory of planetary motion covers a wider range, which can realize the radial shearing of the slurry in the mixing cylinder 1 to further disperse carbon particle agglomerates, eliminate local concentration unevenness, and make the activated carbon particles fully dispersed in the radial range.

[0049] Axial forced circulation to eliminate the concentration difference between the upper and lower layers: While the steering wheel 69 revolves, it synchronously drives the spiral conveying rod 14 inside the conveying pipe 13 to make a circular motion around the drive shaft 66. The spiral conveying rod 14 keeps rotating synchronously with the transmission of the steering wheel 69, forming a continuous axial pumping effect inside the conveying pipe 13. This pumping action can continuously draw the low-concentration slurry at the top of the mixing cylinder 1 from the top of the conveying pipe 13, and after being conveyed by the spiral, it is discharged from the bottom of the conveying pipe 13 to the lower layer of slurry, forming a forced circulation and exchange between the upper and lower layers of slurry. This axial forced circulation structure directly opens up the material exchange channel between the upper and lower layers of slurry. Combined with the lifting effect of bottom aeration and the radial mixing of planetary stirring, it forms a three-dimensional homogenization system, which can maintain the uniform concentration of slurry throughout the cylinder for a long time. It completely solves the problem of low upper layer concentration and high lower layer concentration caused by the sedimentation of activated carbon particles, and provides a stable source of slurry for subsequent quantitative addition. Automated timed and quantitative dosing: When the process system needs to add activated carbon slurry, the external controller controls the solenoid valve 33 to open and close intermittently according to the preset process parameters (dosing frequency, single dosing amount). Compressed air is intermittently input into the air chamber of the diaphragm pump 2 through the air inlet pipe 32, driving the diaphragm pump 2 to run intermittently according to the set rhythm. The diaphragm pump 2 draws the activated carbon slurry with uniform and stable concentration in the mixing cylinder 1 through the liquid inlet pipe 31, and delivers it to the target solution tank or process point in a timed and quantitative manner through the liquid outlet pipe 35.

[0050] This automated dosing mode completely replaces the traditional manual weighing and dosing method, enabling 24-hour continuous operation, significantly reducing the labor intensity of operators, improving dosing efficiency, and precisely controlling the dosing cycle and single dosing amount through electronic control program, completely avoiding problems such as overtime dosing, missed dosing, or dosing amount deviation caused by human factors, ensuring the stability of the process system and the consistency of the treatment effect.
