Description

Technical Field

[0001] The invention relates to the technical field of quicklime reaction equipment, in particular to a multi-stage linkage quicklime digestion reaction device. Background Art

[0002] In the chemical industry, a multi-stage linkage quicklime digestion reactor is used to efficiently react quicklime with water to produce calcium hydroxide. This reactor utilizes innovative mechanical structures, combining crushing, stirring, and heat recovery functions to improve reaction efficiency and product quality. Its core function is to ensure thorough crushing and uniform mixing of quicklime particles with water through a multi-stage linkage design, while also recovering the heat generated during the reaction. Widely used in industries such as building materials and environmental protection, it plays a significant role in optimizing production processes and reducing energy consumption.

[0003] Traditional quicklime digestion reaction equipment has significant shortcomings. In the crushing process, traditional devices rely on single mechanical crushing and lack dynamic impact and grading treatment mechanisms, resulting in insufficient crushing of quicklime particles. Incompletely reacted block materials easily cause waste of resources. During the reaction process, the stirring structure is single, and it is impossible to achieve uniform dispersion of materials. In addition, there is a lack of anti-clogging design, and particles are easily accumulated on the filter plate or conveying channel, affecting the continuity of the reaction. The heat recovery efficiency is low, and the heat generated by the reaction is not effectively utilized, which increases energy consumption. In addition, traditional equipment lacks real-time monitoring and adjustment functions of the reaction process, making it difficult to adapt to different raw material particle sizes and reaction conditions, resulting in unstable product quality. These problems restrict the production efficiency and economy of traditional equipment, and it is urgent to improve its comprehensive performance through multi-stage linkage, dynamic cleaning and heat recovery technology.

[0014] (3) Beneficial effects The present invention provides a multi-stage linkage quicklime digestion reaction device, which has the following beneficial effects: (1) In this multi-stage linkage quicklime digestion reaction device, the rotation of the No. 1 pressure plate will squeeze the elastic plate and cause the elastic plate to bend. When the No. 1 pressure plate passes over the elastic plate, the elastic plate will instantly reset, that is, it will generate an instant impact force on the crushed small lime blocks, further helping to crush the quicklime blocks, thereby greatly improving the reaction efficiency of the quicklime during the reaction, avoiding the problem of material waste caused by incomplete reaction of the quicklime, and the crushed quicklime powder enters the bottom of the crushing tube through the No. 1 filter disk, and the rotation of the rotating shaft will synchronously drive the diffusion plate to rotate, and the quicklime powder on the No. 2 filter disk will be cleaned synchronously by the inclined diffusion plate to avoid clogging of the No. 2 filter disk, and the quicklime powder will be gradually broken up by the cleaning groove on the diffusion plate, thereby ensuring that the quicklime powder gradually passes through the No. 2 filter disk, further avoiding clogging of the No. 2 filter disk, and at the same time, it can also avoid the quicklime powder being squeezed at the bottom of the crushing tube, resulting in excessive density and forming blocks that are difficult to pass through the No. 2 filter disk.

[0015] (2) In this multi-stage linkage quicklime digestion reaction device, the quicklime powder passes through the bottom of the crushing tube and enters the closed disk through the second filter disk. At the same time, the rotating shaft will drive the adapter disk to rotate, and the adapter disk will drive the rotating ring to rotate, thereby prompting the spiral plate to start rotating. The rotating spiral plate gradually transports the quicklime powder, so that the quicklime powder enters the top of the crushing tube through the spiral plate, and enters the reaction tube through the discharge port at the top of the crushing tube, and then falls down to the bottom of the reaction tube. The interior of the adapter shaft is set to be hollow. At this time, water is passed into the interior of the adapter shaft, and the stirring rod connected to it is connected to the stirring rod. The quicklime powder is diffused through the through holes to promote the reaction of the quicklime powder. The quicklime powder can be further helped to diffuse by freely falling from the top of the reaction tube to the bottom, thereby enhancing the reaction effect. At the same time, if quicklime lumps occur during the transportation process, the free fall effect can be used to further help break the quicklime blocks to improve the reaction effect. The rotation of the rotating shaft will synchronously drive the transfer shaft to rotate, and the rotation of the transfer shaft will prompt the stirring rod to rotate, thereby achieving uniform water delivery in the process of stirring the quicklime powder, so that the water evenly enters the quicklime powder, thereby further improving the reaction effect of the quicklime.

[0016] (3) In this multi-stage linkage quicklime digestion reaction device, a large amount of hot steam will be generated when the quicklime is reacting. The generated hot steam will enter the outlet pipe through the outlet ring at the top of the reaction tube, and then enter the gas gathering ring through the outlet pipe. The heat recovery in the quicklime reaction process is achieved through the collection of the gas gathering ring, thereby greatly improving the utilization effect of the quicklime. After the quicklime falls from the discharge port, it will fall on the gathering hood and will be evenly introduced into the bottom of the reaction tube through the No. 1 scraper connected to the rotating shaft. In addition, the trumpet-shaped gathering hood can also greatly reduce the hot steam generated in the reaction process from passing through the gathering hood. The amount of heat can be increased, thereby further improving the heat recovery effect, and through the multi-stage conveying effect, the problem of quicklime clogging can be greatly reduced. When the stirring rod rotates, the cleaning plate will be driven to rotate through the adapter rod, and the inner surface of the outlet ring will be cleaned at a uniform speed by the rotating cleaning plate to avoid the lime carried in the hot steam clogging the outlet ring and affecting the heat recovery effect. The rotation of the adapter rod will simultaneously drive the No. 2 scraper to rotate, and the bottom plate will be cleaned by the rotating No. 2 scraper, and the quicklime in reaction on the bottom plate will be scraped by the No. 2 scraper, thereby further improving the reaction effect of the quicklime and avoiding waste of quicklime.

[0024] The inner surface of the bottom of the crushing tube 43 is rotatably connected to a rotating ring 414, and the inner surface of the rotating ring 414 is rotatably connected to a closing disk 415. The edge bottom surface of the closing disk 415 is fixedly connected to the bottom of the crushing tube 43 through a connecting rod. The upper surface of the closing disk 415 is fixedly connected to a guide block 416.

[0025] The width of the closing disk 415 is set to half of the rotating ring 414, the bottom outer surface of the rotating shaft 46 is rotatably connected to the adapter disk 417, the outer surface of the adapter disk 417 is rotatably connected to the inner surface of the rotating ring 414, and the upper surface of the rotating ring 414 is fixedly connected to the spiral plate 418, which is set in the gap between the pulverizing tube 43 and the pulverizing cylinder 42, and the top outer surface of the pulverizing cylinder 42 is penetrated by a discharge port 419.

[0026] A gathering hood 420 is provided below the crushing cylinder 42. The gathering hood 420 is configured in a trumpet shape and is fixedly connected to the bottom inner surface of the reaction tube 1. The bottom outer surface of the rotating shaft 46 is fixedly connected to a scraper No. 421 through a connecting rod. The scraper No. 421 is configured at an angle and is attached to the inner surface of the gathering hood 420.

[0027] Second embodiment: Figures 1 to 8As shown, the reaction mechanism 5 includes a transfer shaft 51, the top of the transfer shaft 51 is fixedly connected to the bottom of the rotating shaft 46, the bottom of the transfer shaft 51 passes through and is rotatably connected to the middle upper surface of the base plate 2, and the top of the reaction tube 1 is fixedly engaged with an air outlet ring 52, the outer surface of the air outlet ring 52 is passed through and fixedly connected with an air outlet pipe 53, and the bottom of the air outlet pipe 53 passes through and is fixedly connected to the upper surface of the gas gathering ring 3.

[0028] The interior of the adapter shaft 51 is set to be hollow, and the outer surface of the adapter shaft 51 is fixedly connected to a collar 54, and the outer surface of the collar 54 is fixedly connected to a stirring rod 55. Three stirring rods 55 are set in a group, and three groups of stirring rods 55 are set at fixed intervals around the central axis of the collar 54. The stirring rods 55 are set to be hollow, and the stirring rods 55 are connected to the adapter shaft 51. A through hole is opened through the outer surface of the stirring rod 55, and the outer end of the stirring rod 55 is fixedly connected to the adapter rod 56. The top of the adapter rod 56 is fixedly connected to a cleaning plate 57. The outer surface of the cleaning plate 57 is attached to the inner surface of the air outlet ring 52. The bottom of the adapter rod 56 is fixedly connected to the No. 2 scraper 58. The No. 2 scraper 58 is set at an angle and is attached to the upper surface of the bottom plate 2.

[0029] During operation, when quicklime needs to be digested, quicklime can be put into the top of the crushing tube 43 and the motor 45 is started. After the motor 45 is started, the rotating shaft 46 will be driven to rotate. As the rotating shaft 46 rotates, the No. 1 pressure plate 48 will start to rotate, thereby cooperating with the elastic plate 49 to crush the quicklime blocks in the quicklime through the cone thorns. The rotation of the No. 1 pressure plate 48 will squeeze the elastic plate 49 and cause the elastic plate 49 to bend. When the No. 1 pressure plate 48 passes over the elastic plate 49, the elastic plate 49 is instantly reset, that is, a momentary impact force is generated on the crushed small lime blocks, further helping to crush the quicklime blocks, thereby greatly improving the reaction efficiency of the quicklime during the reaction, and avoiding the problem of material waste caused by incomplete reaction of the quicklime. The crushed quicklime powder passes through the No. 1 filter disc 47 and enters the bottom of the crushing tube 43. When the rotating shaft 46 rotates, it will synchronously drive the diffusion plate 411 to rotate. The quicklime powder on the No. 2 filter disc 410 is cleaned synchronously by the inclined diffusion plate 411 to avoid clogging of the No. 2 filter disc 410. The quicklime powder is gradually broken up by the cleaning groove 412 on the diffusion plate 411, thereby ensuring that the quicklime powder gradually passes through the No. 2 filter disc 410, further avoiding clogging of the No. 2 filter disc 410. At the same time, it can also prevent the quicklime powder from being squeezed at the bottom of the crushing tube 43, resulting in excessive density and forming blocks that are difficult to pass through the No. 2 filter disc 410. The quicklime powder that passes through the No. 2 filter disc 410 enters the closing disc 41 through the bottom of the crushing tube 43. 5, and at the same time, the rotation of the rotating shaft 46 drives the adapter plate 417 to rotate, and the adapter plate 417 drives the rotating ring 414 to rotate, thereby prompting the spiral plate 418 to start rotating, and the rotating spiral plate 418 gradually conveys the quicklime powder, so that the quicklime powder enters the top of the crushing cylinder 42 through the spiral plate 418, and enters the reaction tube 1 through the discharge port 419 at the top of the crushing cylinder 42, and then falls downward to the bottom of the reaction tube 1. The interior of the adapter shaft 51 is set to be hollow. At this time, water is passed into the interior of the adapter shaft 51 and diffused through the through hole on the stirring rod 55 connected thereto to prompt the quicklime powder to react. The quicklime powder can be further diffused by freely falling from the top of the reaction tube 1 to the bottom. The reaction effect is enhanced. At the same time, if there is a phenomenon of quicklime caking during the transportation process, the free fall effect can be used to further help break the quicklime blocks to improve the reaction effect. The rotation of the rotating shaft 46 will synchronously drive the adapter shaft 51 to rotate, and the rotation of the adapter shaft 51 will cause the stirring rod 55 to rotate, thereby realizing uniform water transportation during the stirring of the quicklime powder, so that the water evenly enters the quicklime powder, thereby further improving the reaction effect of the quicklime. The quicklime will generate a large amount of hot steam during the reaction. The generated hot steam will enter the outlet pipe 53 through the outlet ring 52 at the top of the reaction tube 1, and enter the gas gathering ring 3 through the outlet pipe 53. The heat recovery during the quicklime reaction process is realized through the collection of the gas gathering ring 3.The utilization effect of quicklime is thereby greatly improved. After the quicklime falls from the discharge port 419, it falls on the gathering cover 420 and is evenly introduced into the bottom of the reaction tube 1 through the scraper 421 connected to the rotating shaft 46. The trumpet-shaped gathering cover 420 can also greatly reduce the amount of hot steam generated during the reaction process passing through the gathering cover 420, thereby further improving the heat recovery effect. The multi-stage conveying effect can also greatly reduce the problem of quicklime blockage. When the stirring rod 55 rotates, it drives the cleaning plate through the adapter rod 56. The rotating cleaning plate 57 cleans the inner surface of the outlet ring 52 at a uniform speed to prevent lime carried in the hot steam from clogging the outlet ring 52 and affecting the heat recovery effect. The rotation of the adapter rod 56 will simultaneously drive the second scraper 58 to rotate, cleaning the bottom plate 2 and scraping the reacting quicklime on the bottom plate 2, thereby further improving the reaction effect of the quicklime and avoiding quicklime waste. After the quicklime reaction is completed, the bottom plate 2 is lowered to complete the collection of slaked lime.
