Description

Technical Field

[0001] This utility model relates to the field of calcium hydroxide production technology, and in particular to a calcium hydroxide digestion device that automatically adjusts the amount of water added. Background Technology

[0002] Calcium hydroxide is an inorganic compound, commonly known as slaked lime or quicklime. It is a white powdery solid with strong alkalinity and slight solubility in water. It is widely used in construction, chemical industry, food industry and other fields.

[0003] In the production of calcium hydroxide, the digestion reaction of quicklime and water is the core step. However, the control of water addition in existing calcium hydroxide digestion devices mostly relies on manual experience or uses a fixed flow rate. This method cannot be dynamically adjusted according to the feed amount, activity of quicklime, and the actual progress of the digestion reaction, resulting in an inaccurate water-lime ratio. An improper water-lime ratio will lead to incomplete digestion, leaving unreacted quicklime in the product and reducing product purity. Alternatively, excessive water addition will result in an excessively high moisture content in the product, affecting product quality and subsequent processing, and making it impractical. Therefore, it is necessary to redesign a calcium hydroxide digestion device that automatically adjusts the water addition to address the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic water-adjusting calcium hydroxide digestion device.

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

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 An automatic water-regulating calcium hydroxide digestion device includes a base plate 1 and a digestion tank 2. Multiple support legs 4 are fixedly installed on the outer wall of the digestion tank 2 via a fixing sleeve 3. A fixing plate 5 is fixedly installed on the outer wall of the digestion tank 2. A connecting plate 7 is fixedly installed on the upper surface of the fixing plate 5 via a lifting mechanism. The lifting mechanism includes an electric actuator 6 fixedly installed on the upper surface of the fixing plate 5. The telescopic end of the electric actuator 6 is fixedly connected to the bottom wall of the connecting plate 7. The electric actuator 6 precisely controls the lifting and lowering of the connecting plate 7 through its telescopic movement, thereby driving a connected cover plate 8 to open and close. Convenient and highly automated, it facilitates equipment maintenance and material addition. A cover plate 8 is slidably installed on the upper end face of the digester 2. The outer wall of the connecting plate 7 is fixedly connected to the outer wall of the cover plate 8. A sealing gasket 9 that mates with the upper end face of the digester 2 is fixedly installed on the bottom wall of the cover plate 8. The sealing gasket 9 is made of vulcanized rubber. When the cover plate 8 is closed, the vulcanized rubber sealing gasket 9 can tightly fit the digester 2 to form a good sealing effect, effectively preventing the dust generated during the digestion reaction from overflowing and the water vapor from escaping. This ensures a clean production environment and avoids material waste and environmental pollution.

[0023] A rotating rod 10 is rotatably installed through the bottom wall of the cover plate 8. A motor 11 connected to the rotating rod 10 is fixedly installed on the upper surface of the cover plate 8. Multiple stirring rods 13 are fixedly installed on the outer wall of the rotating rod 10 through a connecting mechanism. The connecting mechanism includes a connecting sleeve 12 fixedly installed on the outer wall of the rotating rod 10. The end of each stirring rod 13 is fixedly connected to the outer wall of the connecting sleeve 12. The connecting sleeve 12 firmly fixes the stirring rod 13 to the rotating rod 10, so that when the rotating rod 10 rotates, it can drive multiple stirring rods 13 to rotate synchronously, which can fully stir the quicklime and water in the digester 2, increase the contact area between materials, and promote rapid and uniform digestion. To ensure uniform reaction and improve product quality, a connecting block 14 is fixedly installed at the end of the rotating rod 10. Scrapers 16 are fixedly installed on both outer walls of the connecting block 14 via a connecting mechanism. The connecting mechanism includes a connecting rod 15 fixedly installed on the outer wall of the connecting block 14. The end of the connecting rod 15 is fixedly connected to the outer wall of the scraper 16. The scraper 16 is connected to the connecting block 14 via the connecting rod 15. As the rotating rod 10 rotates, the scraper 16 moves close to the inner wall of the digester 2, which can promptly scrape off the material adhering to the tank wall, prevent material accumulation from affecting the reaction effect and the cleanliness of the tank, reduce the frequency and difficulty of manual cleaning, and ensure the continuous and stable operation of the equipment.

[0024] A liquid level sensor 17 is fixedly installed on the inner wall of the digester 2. A controller 19 is fixedly installed on the outer wall of the digester 2 through a support mechanism. The support mechanism includes a support plate 18 fixedly installed on the outer wall of the digester 2. The controller 19 is fixedly installed on the upper surface of the support plate 18. The controller 19 is the control core of the entire device. It receives data signals from components such as the liquid level sensor 17 and controls equipment such as the electric push rod 6, motor 11, and water pump 21 according to a preset program. This enables automatic adjustment of the water addition and coordinated work of various components of the device, ensuring efficient and stable digestion. A water tank 20 is fixedly installed on the upper surface of the bottom plate 1. A water pump 21 is fixedly installed on the upper surface of the water tank 20. The outer wall of the water inlet pipe of the water pump 21 extends into the interior of the water tank 20. A connecting pipe 22 is fixedly installed through the upper surface of the cover plate 8. The outer wall of the water outlet pipe of the water pump 21 is fixedly connected to the outer wall of the connecting pipe 22 through a telescopic hose 23.

[0025] When this utility model is in use, when a calcium hydroxide digestion reaction is required, the operator first issues an instruction through the controller 19 to start the electric push rod 6. The telescopic end of the electric push rod 6 pushes the connecting plate 7 upward, causing the cover plate 8, which is fixedly connected to the connecting plate 7, to slide upward along the upper surface of the digestion tank 2, opening the digestion tank 2. At this time, quicklime is put into the tank from the open top of the digestion tank 2 through an external conveying device.

[0026] After feeding is completed, the controller 19 controls the electric push rod 6 to retract again, so that the cover plate 8 falls smoothly. The vulcanized rubber sealing gasket 9 on the bottom wall of the cover plate 8 fits tightly against the upper end face of the digester 2, forming a good seal to prevent dust from overflowing and water vapor from escaping during the reaction. Then, the controller 19 calculates the required amount of water to be added according to the preset water-cement ratio, and then sends a start signal to the water pump 21. The water pump 21 starts to run and draws water from the water tank 20. The water is transported to the digester 2 through the telescopic hose 23 and the connecting pipe 22. During the water addition process, the liquid level sensor 17 monitors the liquid level in the tank in real time and continuously transmits the data to the controller 19. When the liquid level reaches the calculated target value, the controller 19 immediately controls the water pump 21 to stop working, completing the precise water addition.

[0027] Next, the controller 19 starts the motor 11, which drives the rotating rod 10 to rotate. The rotating rod 10, through the connecting sleeve 12, causes multiple stirring rods 13 to start stirring the quicklime and water in the digestion tank 2, so as to promote the thorough mixing of the two and accelerate the digestion reaction. At the same time, the connecting block 14 at the end of the rotating rod 10 drives the scraper 16 to rotate closely against the inner wall of the digestion tank 2 through the connecting rod 15, so as to scrape off the material adhering to the tank wall in time, so as to avoid the accumulation of material affecting the reaction effect and the cleanliness of the tank.

[0028] During the digestion reaction, the liquid level sensor 17 continuously monitors the liquid level changes and feeds the data back to the controller 19 in real time. If the liquid level drops due to the consumption of water in the reaction, the controller 19 controls the water pump 21 to start again to replenish water based on the liquid level data, so as to realize the dynamic adjustment of the amount of water added and ensure that the reaction is carried out under suitable conditions. When the reaction is completed, the discharge port at the bottom of the digestion tank 2 is opened to discharge the prepared calcium hydroxide product. Then, the electric actuator 6 is started again to raise the cover plate 8, so that the operator can check and clean the inside of the digestion tank 2 and prepare for the next digestion reaction.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
