Description

Technical Field

[0002] The raw material mixing equipment for the production and processing of light calcium carbonate is an integrated device specifically designed for the preparation of light calcium carbonate. Through the synergistic optimization of mechanical structure and process flow, it achieves efficient digestion of quicklime and water and carbon dioxide carbonation reaction, ensuring stable product quality and reducing production costs. In the process of reacting quicklime with water, there may be large particles of quicklime. However, when large particles of quicklime react with water, due to their high hardness and slow reaction, incomplete digestion may occur in some areas, leading to coarsening of the particles. Summary of the Invention

[0003] The purpose of this invention is to provide a raw material mixing device for the production and processing of light calcium carbonate. The filter frame drives the roller to rotate. When the roller rotates onto the inclined block, it rolls along the inclined surface of the block. Due to the undulating surface of the inclined block, the filter frame vibrates up and down when it rotates, causing the quicklime inside the filter frame to be filtered. The fine quicklime is filtered into the mixing tank and reacts with the water inside the mixing tank.

[0010] Preferably, the circulation tank is provided with an inlet and an outlet at both ends, the outlet of the circulation tank is connected to the collection box, the collection box is provided with a water pump, and the output end of the water pump is fixedly connected to the first transmission pipe.

[0011] Preferably, an air pump is fixedly installed inside the air storage tank. The output end of the air pump is fixedly connected to one set of branches of the third transmission pipe.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the filter frame drives the roller to rotate. When the roller rotates onto the inclined block, it rolls along the inclined surface of the block. Due to the undulations of the inclined block surface, the filter frame vibrates up and down as it rotates, causing the quicklime inside the filter frame to be filtered. The fine quicklime is filtered into the mixing tank and reacts with the water inside the mixing tank. This prevents larger quicklime particles from reacting with the water, which would lead to incomplete digestion and coarsening of the quicklime particles during the reaction.

[0014] 2. In this invention, water is introduced into the circulation tank through the inlet. The water enters the circulation tank and circulates. The water absorbs the heat inside the mixing tank, thereby dissipating heat from the inside of the mixing tank. This prevents excessive heat from being generated when quicklime is mixed with water, which could lead to localized overheating of the mixing tank and coarse calcium hydroxide crystals.

[0015] 3. Because the gas storage tank of this invention is made of seamless aluminum alloy, it has excellent water resistance and thermal conductivity. Therefore, the gas storage tank transfers the residual heat in the water to the carbon dioxide inside the tank, thereby preheating the carbon dioxide. The temperature of the preheated carbon dioxide is more matched with the temperature of the slurry in the mixing tank, which can significantly improve the dissolution efficiency and diffusion rate of carbon dioxide in lime milk, accelerate the carbonization reaction rate, and make the carbonization process more uniform and complete.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0019] See Figures 1 to 7 As shown, the present invention provides a raw material mixing device for the production and processing of light calcium carbonate, including a filter assembly 1. The filter assembly 1 includes a protective barrel 11. A filter frame 12 is rotatably installed inside the protective barrel 11. A roller 13 is fixedly installed on one side of the filter frame 12. An inclined block 14 is slidably connected to one end of the roller 13. The bottom of the filter assembly 1 is connected to the stirring assembly 2. The stirring assembly 2 includes a stirring tank 21 connected to the protective tank 11. A stirring tube 24 is rotatably installed inside the stirring tank 21. Multiple sets of spray pipes 25 are connected to the stirring tube 24. Stirring blades 26 are fixedly installed on both sides of each set of spray pipes 25. One end of the stirring tube 24 is fixedly connected to the bottom of the filter frame 12 through a hollow rod 15. The stirring tank 21 is provided with a circulation tank 27. The output end of the circulation tank 27 is connected to a collection box 28. The collection box 28 is provided with a first transmission pipe 210. One end of the first transmission pipe 210 is connected to a second transmission pipe 211. One end of the second transmission pipe 211 is connected to one end of the stirring tube 24 through the hollow rod 15. A gas storage tank 212 is fixedly installed inside the collection box 28. A third transmission pipe 214 is connected inside the gas storage tank 212. One end of the third transmission pipe 214 is connected to the other end of the second transmission pipe 211. The staff pours water into the mixing tank 21 through the inlet. Then, they open the first solenoid valve on the feed pipe 18 and pour quicklime into the filter frame 12 through the feed pipe 18. The motor 22 is started, and the motor 22 drives the mixing pipe 24 to rotate through the rotating shaft 23. The mixing pipe 24 drives the filter frame 12 to rotate, and then the filter frame 12 drives the roller 13 to rotate. When the roller 13 rotates onto the inclined block 14, as the roller 13 rolls along the inclined surface of the inclined block 14, the filter frame 12 vibrates up and down when it rotates due to the undulating surface of the inclined block 14. This causes the quicklime inside the filter frame 12 to vibrate and filter, allowing the fine quicklime to be filtered into the mixing tank 21 and react with the water inside the mixing tank 21. This prevents larger quicklime particles from reacting with the water, which could lead to incomplete digestion and coarsening of the quicklime particles. Additionally, the filter frame 12 and the protective barrel 11 are equipped with telescopic plates. When the filter frame 12 vibrates up and down, the telescopic plates extend and retract to prevent quicklime from entering the connection between the roller 13 and the inclined block 14 and causing blockage, thus ensuring the normal operation of the filter assembly 1. Since the two sets of protrusions on the outside of the hollow rod 15 slide on the two sets of grooves inside the stirring tube 24, the hollow rod 15 is slidably connected to the inside of the stirring tube 24 through the two sets of protrusions and the two sets of grooves. When the filter frame 12 vibrates up and down, it will drive the hollow rod 15 to move inside the stirring tube 24, without interfering with the stirring tube 24 driving the filter frame 12 to rotate through the hollow rod 15. The annular baffle is used to shield and protect the mixing tube 24 and the hollow rod 15, preventing quicklime from drifting into the connection between the mixing tube 24 and the hollow rod 15, and ensuring the stable operation of the mixing tube 24 and the hollow rod 15. When quicklime is filtered into the mixing tank 21, the staff opens the second solenoid valve on the feed port on one side of the mixing tank 21 to transfer water into the mixing tank 21 through the feed port. At this time, the motor 22 drives the mixing tube 24 to rotate through the rotating shaft 23. The mixing tube 24 drives the mixing blades 26 to rotate through multiple sets of spray pipes 25 to mix the quicklime and water and improve the reaction rate of quicklime and water. Because quicklime generates a lot of heat when mixed with water, the staff connects water to the circulation tank 27 through the inlet. The water enters the circulation tank 27 and circulates. The water absorbs the heat inside the mixing tank 21, thus dissipating heat from the mixing tank 21 and preventing excessive heat from being generated when quicklime is mixed with water. This prevents local overheating of the mixing tank 21, which could lead to coarse calcium hydroxide crystals. The water that has circulated inside the circulation tank 27 will flow into the collection tank 28 for storage through the drain outlet of the circulation tank 27. Since the reaction between quicklime and water is exothermic, the temperature can reach 90 to 100 degrees Celsius. At this time, the water will absorb heat and the water temperature will rise as it flows inside the circulation tank 27. The water discharged into the collection tank 28 will heat the gas storage tank 212. Since the gas storage tank 212 is made of seamless aluminum alloy, it has excellent water resistance and thermal conductivity. Therefore, the gas storage tank 212 transfers the residual heat in the water to the carbon dioxide in the tank, realizing the preheating of the carbon dioxide. The temperature of the preheated carbon dioxide is more matched with the temperature of the slurry in the mixing tank 21, which can significantly improve the dissolution efficiency and diffusion rate of carbon dioxide in lime milk, accelerate the carbonization reaction rate, and make the carbonization process more uniform and complete. When the temperature sensor 216 detects that the water source has reached the target temperature for heat dissipation inside the mixing tank 21 through the circulation tank 27, the water supply is stopped. The circulating water then flows into the collection tank 28. At this time, the gas storage tank 212 is heated by the heat from the water in the collection tank 28, causing the carbon dioxide temperature inside the tank to rise and the internal pressure to increase. The pressure sensor 215 detects this increase in internal pressure in the gas storage tank 212, reaching its set value. The pressure sensor 215 then sends a signal to the fourth solenoid valve on the third transmission pipe 214, controlling the fourth solenoid valve to open the passage of the third transmission pipe 214. The gas storage tank 212, heated by the warm water, then experiences a pressure reduction. As the pressure rises, a pressure difference is formed inside the tank that is higher than that inside the stirring tube 24. Under the action of the pressure difference, carbon dioxide automatically flows into the stirring tube 24 through one of the branches of the first transmission tube 210. The stirring tube 24 then delivers the carbon dioxide to the inside of multiple sets of nozzles through multiple sets of spray pipes 25. The multiple sets of nozzles spray the carbon dioxide into the calcium hydroxide formed by water and quicklime. As the stirring tube 24 drives the multiple sets of stirring blades 26 to rotate through the multiple sets of spray pipes 25, the multiple sets of spray pipes 25 drive the multiple sets of nozzles to rotate, making the carbon dioxide sprayed by the multiple sets of nozzles more uniform. This prevents the carbon dioxide from being sprayed unevenly onto the calcium hydroxide, resulting in uneven distribution of calcium carbonate and substandard purity of calcium carbonate, which would affect subsequent processes. The carbon dioxide is automatically transferred by means of the self-pressurization of the gas storage tank 212 and the opening and closing of the fourth solenoid valve controlled by the pressure sensor 215, and by the pressure difference. This method requires no additional power, consumes less energy, and has a simpler structure. With the rotation and spraying of the stirring pipe 24, spray pipe 25, stirring blade 26 and nozzle, the carbon dioxide delivery can be more stable and the distribution more uniform. This achieves automated control, reduces manual operation, and improves production efficiency and operational safety. Additionally, if the temperature sensor 216 detects that the internal temperature of the mixing tank 21 has reached the process requirement for introducing carbon dioxide, but the pressure sensor 215 detects that the internal pressure of the gas storage tank 212 has not reached the set threshold and cannot automatically supply gas, the air pump 213 can be directly started. The air pump 213 pressurizes the carbon dioxide inside the gas storage tank 212 and transmits it to the mixing tube 24 through another branch of the third transmission pipe 214 to ensure a stable and continuous supply of carbon dioxide required for the carbonization reaction. One-way valves on one branch of the third transmission pipe 214 are used to prevent carbon dioxide from flowing back when the air pump 213 starts pressurizing, ensuring that the gas is only transported in one direction to the stirring pipe 24, avoiding pressure leakage and unstable gas supply. Additionally, if the water source in the collection box 28 heats the carbon dioxide in the storage tank 212, causing the pressure inside the tank to reach the set threshold of the pressure sensor 215, but before the carbon dioxide supply time has arrived, the staff can open the valve on the air inlet pipe connected to the storage tank 212 to release the pressure inside the storage tank 212 through the air inlet pipe. After the calcium carbonate is prepared, the valve at the outlet of the mixing tank 21 is opened to discharge the calcium carbonate. After the discharge is completed, the operator opens the third solenoid valve on the first transmission pipe 210 and closes the fourth solenoid valve on the third transmission pipe 214, and starts the water pump 29 inside the collection tank 28. The water pump 29 transmits the water source inside the collection tank 28 through the first transmission pipe 210 and the second transmission pipe 211 to the mixing pipe 24. The mixing pipe 24 then delivers the water source through multiple sets of spray pipes 25 to multiple sets of nozzles. The multiple sets of nozzles spray the water source into the mixing tank 21. With the rotation of the mixing pipe 24, the inside of the mixing tank 21 is cleaned to prevent residual calcium carbonate particles and unreacted calcium hydroxide or impurities from being mixed into the next batch of raw materials, which would lead to a decrease in product purity, color difference, uneven particle size, or unstable performance. Additionally, since one end of the second transmission pipe 211 is slidably connected to the inside of the hollow rod 15, when the first transmission pipe 210 transmits water to the inside of the stirring pipe 24 through the second transmission pipe 211, and the third transmission pipe 214 transmits carbon dioxide to the inside of the stirring pipe 24 through the second transmission pipe 211, it will not affect the normal operation of the hollow rod 15 and the stirring pipe 24 in cooperating to drive the filter frame 12. Staff can open the valve on the air inlet pipe connected to the gas storage tank 212 to replenish carbon dioxide into the gas storage tank 212 through the air inlet pipe, ensuring that the required amount of carbon dioxide is sufficient. After the production of light calcium carbonate is completed, the staff can open the barrel door on the protective barrel 11 to clean the large particles of quicklime left on the filter frame 12, so as to avoid clogging of the filter frame 12 and ensure continuous production.

[0020] In an optional embodiment, a telescopic plate is provided on one side of the filter frame 12, and one side of the telescopic plate is fixedly connected to the inside of the protective barrel 11. An annular baffle is provided on the outside of the stirring tube 24, and one end of the annular baffle is fixedly connected to the bottom of the filter frame 12.

[0021] It should be noted that the telescopic plate can prevent quicklime from entering the connection between the roller 13 and the inclined block 14 and causing blockage, and the annular baffle is used to protect the connection between the mixing tube 24 and the hollow rod 15 to prevent powder from entering and affecting operation.

[0022] In an optional embodiment, the bottom of the mixing tank 21 is provided with a fixing frame, on which a motor 22 for driving the mixing tube 24 is installed, and one side of the collection box 28 is connected to the fixing frame at the bottom of the mixing tank 21.

[0023] It should be noted that the mounting bracket is used to fix the motor 22 and the collection box 28, thereby improving the overall structural stability of the equipment.

[0024] In an optional embodiment, a rotating shaft 23 is fixedly connected to the output end of the motor 22. One end of the rotating shaft 23 passes through the bottom of the mixing tank 21 and is connected to the mixing tube 24.

[0025] It should be noted that the motor 22 drives the stirring tube 24 to rotate through the rotating shaft 23, providing power for filtration and stirring.

[0026] In an optional embodiment, the stirring tube 24 has two sets of grooves inside, and the hollow rod 15 has two sets of protrusions on the outside that slide inside the two sets of grooves. The hollow rod 15 is slidably connected to the inside of the stirring tube 24 through the two sets of protrusions and the two sets of grooves. One end of the second transmission tube 211 is slidably connected to the inside of the hollow rod 15.

[0027] It should be noted that, since the two sets of protrusions on the outside of the hollow rod 15 slide on the two sets of grooves inside the stirring tube 24, the hollow rod 15 is slidably connected to the inside of the stirring tube 24 through the two sets of protrusions and the two sets of grooves. When the filter frame 12 vibrates up and down, it will drive the hollow rod 15 to move inside the stirring tube 24, without interfering with the stirring tube 24 driving the filter frame 12 to rotate through the hollow rod 15.

[0031] It should be noted that the circulation tank 27 is used for heat dissipation of the mixing tank 21. After heat exchange, the water is stored in the collection tank 28, and the water pump 29 transports the water in the collection tank 28 to the inside of the mixing tank 21 to complete the cleaning.

[0032] In an optional embodiment, an air pump 213 is fixedly installed inside the air storage tank 212. The output end of the air pump 213 is fixedly connected to one set of branches of the third transmission pipe 214.

A one-way valve is provided on the other set of branches of the third transmission pipe 214. An air inlet pipe is connected to the inside of the air storage tank 212. One end of the air inlet pipe passes through the inside of the collection box 28, and a valve is provided on the air inlet pipe.

[0033] It should be noted that the air pump 213 is used to pressurize and transport carbon dioxide to meet the demand for large-flow gas supply. The air inlet pipe and valve are used to replenish carbon dioxide to the gas storage tank 212. The one-way valve on one of the branches of the third transmission pipe 214 is used to prevent carbon dioxide from flowing back when the air pump 213 is started and pressurized, ensuring that the gas is only transported in one direction to the stirring pipe 24, avoiding pressure leakage and unstable gas supply.

[0034] In an optional embodiment, one end of the first transmission pipe 210 penetrates the interior of the collection box 28, and one end of the first transmission pipe 210 is connected to the interior of the second transmission pipe 211. A third solenoid valve is provided on the first transmission pipe 210.

A fourth solenoid valve is provided on the third transmission pipe 214.

[0035] It should be noted that the third and fourth solenoid valves control the opening and closing of the cleaning water path and the carbon dioxide gas path respectively, realizing automatic switching of the delivery process.

[0036] Working principle: The operator pours water into the mixing tank 21 through the inlet. Then, the operator opens the first solenoid valve on the feed pipe 18 and pours quicklime into the filter frame 12 through the feed pipe 18. The operator starts the motor 22, which drives the mixing pipe 24 to rotate through the rotating shaft 23. The mixing pipe 24 drives the filter frame 12 to rotate, and then the filter frame 12 drives the roller 13 to rotate. When the roller 13 rotates onto the inclined block 14, as the roller 13 rolls along the inclined surface of the inclined block 14, the filter frame 12 vibrates up and down when it rotates due to the undulating surface of the inclined block 14. This causes the quicklime inside the filter frame 12 to vibrate and filter, and the fine quicklime is filtered into the mixing tank 21 to react with the water inside the mixing tank 21. When quicklime is filtered into the mixing tank 21, the staff opens the second solenoid valve on the feed port on one side of the mixing tank 21 to transfer water into the mixing tank 21 through the feed port. At this time, the motor 22 drives the mixing tube 24 to rotate through the rotating shaft 23. The mixing tube 24 drives the mixing blades 26 to rotate through multiple sets of spray pipes 25 to mix the quicklime and water and improve the reaction rate of quicklime and water. Since quicklime generates a lot of heat when mixed with water, the staff connects the water source through the inlet of the circulation tank 27. The water enters the circulation tank 27 and circulates. The water absorbs the heat inside the mixing tank 21, thereby dissipating heat from the inside of the mixing tank 21. After circulating inside the circulation tank 27, the water flows into the collection tank 28 for storage through the drain outlet of the circulation tank 27. Since the reaction between quicklime and water releases heat, the temperature can reach 90 to 100 degrees Celsius. At this time, the water flows inside the circulation tank 27 and absorbs heat, causing the water temperature to rise. The water discharged into the collection tank 28 will heat the gas storage tank 212. Since the gas storage tank 212 is made of seamless aluminum alloy, it has excellent water resistance and thermal conductivity. Therefore, the gas storage tank 212 transfers the residual heat in the water to the carbon dioxide inside the tank, thus preheating the carbon dioxide. When the temperature sensor 216 detects that the water source has reached the target temperature for heat dissipation inside the mixing tank 21 through the circulation tank 27, the water supply is stopped. The circulating water then flows into the collection tank 28. At this time, the gas storage tank 212 is heated by the heat from the water in the collection tank 28, causing the carbon dioxide temperature inside the tank to rise and the internal pressure to increase. The pressure sensor 215 detects this increase in internal pressure in the gas storage tank 212, reaching its set value. The pressure sensor 215 then transmits a signal to the fourth solenoid valve on the third transmission pipe 214, controlling the fourth solenoid valve to open the third transmission pipe 214. When the passage is opened, the gas pressure inside the gas storage tank 212 increases after being heated by warm water, creating a pressure difference higher than that inside the stirring tube 24. Under the action of the pressure difference, carbon dioxide automatically flows into the stirring tube 24 through one of the branches of the first transmission pipe 210. The stirring tube 24 then delivers the carbon dioxide to multiple sets of nozzles via multiple sets of spray pipes 25. The multiple sets of nozzles spray the carbon dioxide into the calcium hydroxide formed by water and quicklime. As the stirring tube 24 drives the multiple sets of stirring blades 26 to rotate through the multiple sets of spray pipes 25, the multiple sets of spray pipes 25 drive the multiple sets of nozzles to rotate, making the carbon dioxide sprayed by the multiple sets of nozzles more uniform. If the temperature sensor 216 detects that the internal temperature of the mixing tank 21 has reached the process requirement for introducing carbon dioxide, but the pressure sensor 215 detects that the internal pressure of the gas storage tank 212 has not reached the set threshold and cannot automatically supply gas, the air pump 213 can be started directly. The air pump 213 pressurizes the carbon dioxide inside the gas storage tank 212 and transmits it to the mixing tube 24 through another branch of the third transmission pipe 214 to ensure a stable and continuous supply of carbon dioxide required for the carbonization reaction. After the calcium carbonate is prepared, the valve at the outlet of the mixing tank 21 is opened to discharge the calcium carbonate. After the discharge is completed, the operator opens the third solenoid valve on the first transmission pipe 210 and closes the fourth solenoid valve on the third transmission pipe 214, and starts the water pump 29 inside the collection tank 28. The water pump 29 transmits the water source inside the collection tank 28 through the first transmission pipe 210 and the second transmission pipe 211 to the mixing pipe 24. The mixing pipe 24 then delivers the water source through multiple sets of spray pipes 25 to multiple sets of nozzles. The multiple sets of nozzles spray the water source into the mixing tank 21, and in conjunction with the rotation of the mixing pipe 24, cleans the inside of the mixing tank 21. After the production of light calcium carbonate is completed, the staff can open the barrel door on the protective barrel 11 to clean the large particles of quicklime left on the filter frame 12, so as to avoid clogging of the filter frame 12 and ensure continuous production.
