Description

Technical Field

[0001] This invention relates to the field of potassium fluorotitanate, and more specifically, to a rapid crystallization apparatus for potassium fluorotitanate. Background Technology

[0002] Existing Chinese patent (CN215609458U) discloses a rapid crystallization device for potassium fluorotitanate:

[0003] By incorporating a refrigeration system throughout the apparatus, a water pump is activated to draw water through pipes to the refrigeration pipes for cooling. The first actuator is then activated, driving a cooling fan to dissipate the cold air generated inside the vessel, rapidly lowering the temperature of the solution and accelerating crystal precipitation. Furthermore, a stirring device is installed throughout the apparatus. The output of the second actuator drives a rotating rod, which agitates the solution inside the vessel, increasing the contact between hydrogen fluoride gas and sodium carbonate solution. Several stirring blades are fixedly installed on the stirring rods to ensure uniform mixing and a more complete and rapid reaction between the fluorotitanic acid solution and potassium chloride solution. However, this method has the following drawbacks.

[0004] During the stirring process of the mixed solution in the vessel, the repeated mechanical stirring easily generates a lot of heat, resulting in a high temperature inside the vessel. This leads to a large energy consumption and low cooling efficiency when cooling the mixed solution inside the vessel. Furthermore, since the crystals easily adhere to the inner wall of the vessel, failure to remove the adhered crystals in time prevents the crystallization process from continuing, greatly affecting work efficiency. At the same time, after the mixed solution has cooled and crystallized, the crystals need to be removed. Directly removing the crystals can easily lead to insufficient crystallization. Summary of the Invention

[0005] To overcome the disadvantages of high temperature inside the reactor, which leads to high energy consumption and low cooling efficiency when cooling the mixed solution inside the reactor, this invention provides a rapid crystallization device for potassium fluorotitanate.

[0007] Further explanation: The mixing assembly includes a first motor, a drive shaft, a lead screw, a ring, a first fixed disc, a first fixed block, a first stirring rod, a second fixed block, an elastic element, a connecting rod, a connecting shaft, and a second fixed disc; the first motor is mounted on the upper part of the cylinder; the output shaft of the first motor is fixedly connected to the drive shaft; the drive shaft is rotatably connected to the cylinder; a lead screw is fixedly connected to the lower end of the drive shaft; a ring is screwed onto the lead screw; the ring is fixedly connected to multiple scrapers; both scrapers are in contact with the inner wall of the cylinder; the first fixed disc is fixedly connected to the lower part of the lead screw; the outer ring of the first fixed disc is annular. Five first fixing blocks are fixedly connected at equal intervals; a first stirring rod is fixedly connected to each first fixing block; a second fixing block is fixedly connected to the outer ring surface of the first fixing plate; the second fixing block is fixedly connected to the second stirring rod; an elastic element is sleeved on the outside of the second stirring rod, and one end of the elastic element is fixedly connected to the second fixing block, and the other end of the elastic element is fixedly connected to the second stirring rod; a connecting rod is fixedly connected to the upper part of the second stirring rod; the connecting rod is slidably connected to the inner wall of the cylinder; a connecting shaft is fixedly connected to the lower end of the lead screw; a second fixing plate is fixedly connected to the connecting shaft; the second fixing plate is fixedly connected to multiple baffles.

[0008] To further explain, the inner wall of the cylinder has a spiral groove for cooperating with the movement of the connecting rod.

[0009] To further explain, an arc-shaped rod is provided at the end of the connecting rod away from the second stirring rod.

[0010] To further explain, the scraper is designed in a twisted shape, and bristles are provided on the side near the inner wall of the barrel. Moreover, viewed from above, the multiple scrapers in the ring array cover most of the inner wall of the barrel, which is used to clean the crystals adhering to the inner wall of the barrel.

[0011] To further explain, the second stirring rod is configured in a twisting shape for stirring the mixed solution.

[0012] To further explain, the baffle is designed in an arc shape to work with the air nozzle to create a vortex in the airflow.

[0013] To further explain, the cooling assembly includes a cooling pipe, a connecting valve, a conduit, a fixing rod, and an annular pipe; the cooling pipe is installed on the cylinder; a conduit is fixedly connected to the bottom of the cylinder; a connecting valve is fixedly connected to the lower end of the conduit; two fixing rods, distributed front and rear, are fixedly connected to the bottom of the inner wall of the cylinder; an annular pipe is fixedly connected to the upper part of the two fixing rods; the annular pipe is connected to the conduit; and the annular pipe is fixedly connected to multiple air nozzles.

[0016] The advantages and positive effects of this invention are:

[0017] 1. The mixture is stirred by the rotation of five first stirring rods, and the second stirring rod moves upward during the stirring process, so that the mixture is thoroughly and evenly mixed.

[0018] 2. Heat is absorbed from the outer wall of the cylinder through the cooling pipe, thereby reducing the temperature inside the cylinder. Then, cold air is introduced into the cylinder through three air inlets and a connecting valve, which in turn cools the mixed solution inside the cylinder.

[0019] 3. The expanding mixed solution is broken up by the rotation of multiple baffles, thereby achieving cooling of the mixed solution from the inside out, thus accelerating the cooling rate of the mixed solution. At the same time, the mixed solution is stirred by five first stirring rods and one second stirring rod, which further accelerates the cooling of the mixture and thus accelerates the precipitation of crystals.

[0020] 4. The crystals adhering to the inner wall of the barrel are scraped off by the lower edge of the ring. When thicker crystal blocks are found, multiple scrapers are used to break the crystals before scraping them off by the lower edge of the ring. This effectively prevents crystals from adhering to the inner wall of the barrel and improves production efficiency.

[0021] 5. By rotating two augers, the crystals inside the drum flow through two fixed pipes and are discharged. The crystals are then detected by an external detector, enabling real-time monitoring. This avoids the problem of excessive crystallization and energy waste caused by continuously supplying cold air to the drum, effectively achieving energy-saving production.

[0041] The inner wall of the cylinder 3 has a spiral groove for moving in conjunction with the connecting rod 212.

[0042] An arc-shaped rod is provided at the end of the connecting rod 212 away from the second stirring rod 210.

[0043] The scraper 205 is configured in a twisted shape and has bristles on the side near the inner wall of the barrel 3. Moreover, when viewed from above, the multiple scrapers 205 in the annular array cover most of the inner wall of the barrel 3, which is used to clean the crystals adhering to the inner wall of the barrel 3.

[0044] The second stirring rod 210 is configured in a twisting shape for stirring the mixed solution.

[0045] The baffle 215 is designed to be arc-shaped to work with the nozzle 306 to create a vortex in the airflow.

[0046] The cooling assembly includes a cooling pipe 301, a connecting valve 302, a conduit 303, a fixing rod 304, and an annular pipe 305. The cooling pipe 301 is installed on the cylindrical barrel 3. The conduit 303 is fixedly connected to the bottom of the cylindrical barrel 3. The connecting valve 302 is fixedly connected to the lower end of the conduit 303. Two fixing rods 304, distributed front and rear, are fixedly connected to the bottom of the inner wall of the cylindrical barrel 3.

[0047] Each nozzle 306 is equipped with a branch pipe 3061, which is used to spray gas onto the inner wall of the cylinder 3.

[0048] The detection assembly includes a fixed tube 401 and a second motor 402; two fixed tubes 401 distributed front and rear are fixedly connected to the lower part of the cylinder 3; a second motor 402 is fixedly connected to the lower part of each of the two fixed tubes 401; the output shafts of the two second motors 402 are fixedly connected to an auger 403.

[0049] The elastic element 211 is a spring.

[0050] During mixing: The potassium fluorotitanate rapid crystallization device is manually moved to the designated position. Then, the external air pump is manually connected to three air inlets 32 and one connecting valve 302. The external water pump is then connected to the cooling pipe 301. The clarified fluorotitanate solution and potassium chloride solution are then manually injected into the cylindrical tank 3 through the feed inlet 31. The clarified fluorotitanate solution and potassium chloride solution are hereinafter referred to as the mixed solution. At this time, the mixed solution is located at the bottom of the cylindrical tank 3. Then, the first motor 201 is started. The output shaft of the first motor 201 rotates, driving the transmission shaft 202 to rotate. The rotation of the transmission shaft 202 drives the lead screw 203 to rotate. The rotation of the lead screw 203 drives the first fixed plate 206 to rotate. The rotation of the first fixed plate 206 drives five... The first fixed block 207 rotates, and the rotation of the five first fixed blocks 207 drives the rotation of the five first stirring rods 208, thereby stirring the mixed solution through the rotation of the five first stirring rods 208. At the same time, the rotation of the first fixed plate 206 drives the rotation of the second fixed block 209, and the rotation of the second fixed block 209 drives the rotation of the second stirring rod 210. The rotation of the second stirring rod 210 drives the elastic element 211 and the connecting rod 212 to rotate. At this time, the connecting rod 212 will move upward and rotate along the spiral groove opened on the inner wall of the cylinder 3, thereby compressing the elastic element 211, so that the second stirring rod 210 moves upward during the rotation to stir the mixed solution, thereby making the mixed solution fully and evenly mixed.

[0051] When the connecting rod 212 rotates upward to its limit, the first motor 201 is started. The output shaft of the first motor 201 rotates, causing the transmission shaft 202 to reverse, which in turn causes all related components to reverse, and then causes the connecting rod 212 to reverse and move downward along the spiral groove opened on the inner wall of the cylinder 3. Thus, the mixed solution is stirred by the forward and reverse rotation of the connecting rod 212, so that the mixed solution is mixed evenly.

[0052] During cooling and precipitation: The repeated mechanical stirring of the mixed solution within the cylinder 3 easily generates significant heat, resulting in a high temperature inside the cylinder 3. This leads to a large energy consumption and low cooling efficiency during cooling. At this point, an external water pump is activated, allowing cold water to flow into the cooling pipe 301 and out through the opening at the bottom of the pipe. The cooling pipe 301 absorbs heat from the outer wall of the cylinder 3, thus lowering the temperature inside. Next, an external air pump is activated, allowing cold air to enter the cylinder 3 through three air inlets 32 and a connecting valve 302, further cooling the mixed solution. When the cold air enters the annular pipe 305, it is ejected through multiple air nozzles 306, achieving cooling of the mixed solution inside the cylinder 3. Simultaneously, since the uncrystallized mixed solution is located at the bottom of the cylinder 3 and is in a liquid state, multiple... When the air nozzle 306 blows out cold air, the gas will blow towards the mixed solution, causing the mixed solution to expand. At the same time, it controls the start of the first motor 201. The output shaft of the first motor 201 rotates, driving the transmission shaft 202 to rotate. The rotation of the transmission shaft 202 drives the lead screw 203 to rotate, which in turn drives the connecting shaft 213 to rotate. The rotation of the connecting shaft 213 drives the second fixed disk 214 to rotate, which in turn drives multiple baffles 215 to rotate. The rotation of the multiple baffles 215 breaks up the expanded mixed solution, thereby achieving cooling of the mixed solution from the inside out and accelerating the cooling rate of the mixed solution. At the same time, the cold air is blown to the periphery of the mixed solution through the three air inlets 32 above. Since the transmission shaft 202 is rotating, the mixed solution is stirred again by the five first stirring rods 208 and one second stirring rod 210, which further accelerates the cooling of the mixture and thus accelerates the precipitation of crystals.

[0053] During cleaning: The expanded mixed solution is broken by the rotation of multiple baffles 215, causing crystals to easily adhere to the inner wall of the cylinder 3. At this point, the first motor 201 is started. The output shaft of the first motor 201 rotates, driving the transmission shaft 202 to rotate. The rotation of the transmission shaft 202 drives the lead screw 203 to rotate. The rotation of the lead screw 203 causes the ring 204 to move downwards under the limiting action of the two scrapers 205. Simultaneously, the movement of the ring 204 causes multiple scrapers 205 to move downwards along the inner wall of the cylinder 3. The ring 204 moves and scrapes away the crystals adhering to the inner wall of the cylinder 3 through the lower edge of the ring 204. When thicker crystal blocks are present, multiple scrapers 205 are used to pre-crush the crystals. Since the multiple scrapers 205 in the ring array cover most of the inner wall of the cylinder 3, the adhering crystals are pre-crushed by the multiple scrapers 205 and then scraped away by the lower edge of the ring 204. This effectively avoids crystals adhering to the inner wall of the cylinder 3 and improves production efficiency.

[0054] During testing: When the mixed solution has cooled and crystallized, the crystals need to be discharged. However, directly discharging the crystals can easily lead to insufficient crystallization since the crystals are crystallized within the cylinder 3. At this point, two second motors 402 are controlled to operate. The output shafts of the two second motors 402 rotate, each driving an auger 403 to rotate. The rotation of the two augers 403 causes the crystals in the cylinder 3 to flow through the two fixed pipes 401 and be discharged. Then, an external detector is used to detect the crystals. If the detector detects that the crystallization has not reached its limit, it means that cold air needs to be supplied to the cylinder 3 for further cooling and crystallization. If the detector detects that the crystallization has reached its limit, the external air pump is controlled to stop operating, thereby stopping the supply of cold air to the cylinder 3. This achieves real-time detection of crystallization, avoiding the problem of excessive crystallization and energy waste caused by continuously supplying cold air to the cylinder 3, effectively achieving energy-saving production. When the crystallization limit is reached, valve 4 is manually opened until all the crystals in the cylinder 3 are discharged, thus achieving the detection and discharge of crystals.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
