Description

Technical Field

[0001] This utility model relates to the field of fluorosilicate crystallization, and specifically to a fluorosilicate crystallizer. Background Technology

[0002] Fluorosilicones are a class of compounds formed by the neutralization reaction of fluorosilicic acid with metal cations. A certain concentration of fluorosilicic acid solution and sodium salt solution are continuously or intermittently added to a crystallization tank according to a stoichiometric ratio, thereby producing sodium fluorosilicate through a chemical reaction in the crystallization tank. The sodium fluorosilicate produced has low solubility in water and quickly reaches a supersaturated state in the reaction mixture, thereby precipitating crystals to obtain fluorosilicates.

[0003] The silicate solution and sodium salt solution need to be added in a certain ratio. The existing addition method is relatively simple, which involves adding the solution directly into the crystallizer through a pipe. The amount added is controlled by controlling the addition time. Although it is possible to control the amount of each solution added to achieve a certain ratio, if an emergency occurs, such as a pause in one solution or a sudden blockage, it will result in one solution being added in excess and the other in insufficient quantity. Furthermore, it is inconvenient to replenish the solution later, because it is unknown how much excess solution was added when one solution was paused. Therefore, how to deal with emergencies while ensuring the correct addition amount is the problem that this application aims to solve. Utility Model Content

[0004] Based on the above description, this utility model provides a fluorosilicate crystallizer to solve the problem of low fault tolerance when adding solution in existing crystallizers.

[0010] Furthermore, the sealing component consists of a rod and a sealing block. The sealing block is installed at one end of the rod, and when the sealing component is inserted into the inner cavity of the liquid storage box, the sealing block seals the liquid outlet.

[0011] Furthermore, a discharge section is installed at the bottom of the outer cylinder. The discharge section includes a discharge cylinder, a top plate, a discharge port, a vertical rod, and a groove. The discharge cylinder is fixedly installed at the bottom of the outer cylinder. The top plate and the discharge cylinder are connected by the vertical rod, and the gap between the discharge cylinder and the top plate forms the discharge port. The groove is formed on the top surface of the top plate.

[0012] Furthermore, the top of the top plate is designed as a hemispherical shape, and the top of the sealing plate is also designed as a hemispherical shape, while the sealing plate cooperates with the groove.

[0013] Furthermore, support feet are installed on the side wall of the outer cylinder, and a fixing plate is installed between the support feet. The hydraulic rod is installed on the fixing plate, and the telescopic rod of the hydraulic rod moves through the top plate and the groove of the top plate and then connects to the bottom of the sealing plate.

[0014] Furthermore, a first pipe and a second pipe are installed on the side wall of the outer cylinder. The first pipe and the second pipe are distributed opposite to each other, with the first pipe located at the upper part of the outer cylinder and the second pipe located at the lower part of the outer cylinder.

[0028] Please see Figure 1 , Figure 2 and Figure 3 A fluorosilicate crystallizer includes an outer cylinder 1 and an inner cylinder 2, wherein the inner cylinder 2 is disposed in the inner cavity of the outer cylinder 1; The top of the inner cylinder 2 is equipped with a liquid storage component 5. There are two liquid storage components 5, which are symmetrically distributed on the top of the inner cylinder 2. The liquid storage components 5 are used to receive the solution to be added, and two are provided to facilitate receiving the required solution separately. The liquid storage assembly 5 includes a liquid storage box 501, a sealing element 503, a liquid outlet 504, and a liquid inlet pipe 505. A bracket is installed on the top of the inner wall of the inner cylinder 2, and the liquid storage box 501 is installed on the bracket. The bracket can support the liquid storage box 501. The sealing element 503 is inserted into the inner cavity of the liquid storage box 501. The liquid outlet 504 is located at the bottom of the liquid storage box 501 and faces the inner cavity of the inner cylinder 2. The solution added to the liquid storage box 501 can be discharged into the inner cylinder 2 from the liquid outlet 504. The sealing element 503 is used to block the liquid outlet 504 when it is not necessary to drain the solution, so as to ensure the solution addition amount. When the addition amount is met, the sealing element 503 can be removed to drain the solution into the inner cylinder 2 from the liquid outlet 504.

[0029] The liquid inlet pipe 505 is installed on the top of the liquid storage box 501. The side wall of the liquid storage box 501 is a transparent plate, which makes it easy to observe the amount of solution inside the liquid storage box 501. At the same time, the side wall of the liquid storage box 501 is provided with scale lines, which can more accurately determine the amount of solution. The bottom of the inner cylinder 2 is provided with a discharge port, and a sealing component 6 is provided in the inner cavity of the discharge port. The sealing component 6 is used to block the discharge port.

[0030] The sealing assembly 6 includes a sealing plate 601 and a hydraulic rod 602. The sealing plate 601 is installed on the top of the hydraulic rod 602, and the end of the sealing plate 601 away from the hydraulic rod 602 is inserted into the inner cavity of the discharge port. When discharge is required, the hydraulic rod 602 can be activated to drive the sealing plate 601 to move downward, thereby discharging the crystals in the inner cylinder 2 from the discharge port.

[0031] Please see Figure 2 In this embodiment, a motor 3 is also installed on the bracket at the top of the inner cylinder 2. A stirring rod 4 is installed at the output end of the bottom of the motor 3. The end of the stirring rod 4 away from the motor 3 is inserted into the inner cavity of the inner cylinder 2. Starting the motor 3 can drive the stirring rod 4 to rotate, and the rotating stirring rod 4 can accelerate the mixing of the solution in the inner cylinder 2.

[0032] Please see Figure 3 The liquid storage component 5 in this embodiment also includes an arc groove 502, which is formed on the side wall of the liquid storage box 501. The arc grooves 502 on the two liquid storage boxes 501 together form a circular hole, and the motor 3 is located at the center of the circular hole.

[0033] Please see Figure 3 and Figure 4 In this embodiment, the sealing member 503 consists of a rod and a sealing block. The sealing block is installed at one end of the rod. When the sealing member 503 is inserted into the inner cavity of the liquid storage box 501, the sealing block blocks the liquid outlet 504. The liquid outlet 504 is blocked by inserting the sealing member 503, and the solution in the inner cavity of the liquid storage box 501 can be discharged by pulling out the sealing member 503.

[0034] Please see Figure 2 In this embodiment, the bottom of the outer cylinder 1 is equipped with a discharge section 7. The discharge section 7 includes a discharge cylinder 701, a top plate 702, a discharge port 703, a vertical rod 704, and a groove 705. The discharge cylinder 701 is fixedly installed at the bottom of the outer cylinder 1. The top plate 702 and the discharge cylinder 701 are connected by the vertical rod 704. The gap between the discharge cylinder 701 and the top plate 702 forms the discharge port 703. The discharge port 703 is used to discharge the crystals in the inner cylinder 2. The groove 705 is formed on the top surface of the top plate 702.

[0035] After the sealing part 503 is opened, the crystals in the inner cylinder 2 will fall onto the top plate 702, and then slide down the side wall of the top plate 702, which is the discharge port 703.

[0036] Please see Figure 2 In this embodiment, the top of the top plate 702 is designed as a hemispherical shape, and the top of the sealing plate 601 is also designed as a hemispherical shape. At the same time, the sealing plate 601 cooperates with the groove 705. The hemispherical design allows the crystal to slide more easily from the top plate 702 and the sealing plate 601.

[0037] Please see Figure 2In this embodiment, a support foot is installed on the side wall of the outer cylinder 1, and a fixing plate 8 is installed between the support feet. The hydraulic rod 602 is installed on the fixing plate 8, and the fixing plate 8 provides the hydraulic rod 602 with the support force for installation. At the same time, the telescopic rod of the hydraulic rod 602 moves through the top plate 702 and the groove 705 of the top plate 702 and connects to the bottom of the sealing plate 601. After the hydraulic rod 602 is started, it will drive the sealing plate 601 to move downward from the discharge port, thereby allowing the crystal inside the inner cylinder 2 to be discharged.

[0038] Please see Figure 2 In this embodiment, a first pipe 9 and a second pipe 10 are installed on the side wall of the outer cylinder 1. The first pipe 9 and the second pipe 10 are distributed opposite to each other. The first pipe 9 is located at the upper part of the outer cylinder 1, and the second pipe 10 is located at the lower part of the outer cylinder 1. The first pipe 9 is used to introduce a cooling medium, such as cold water, and the second pipe 10 is used to discharge the cooling medium. The cooling medium is used to cool the mixed solution inside the inner cylinder 2, reduce the solubility of sodium fluorosilicate, and cause it to precipitate crystals.

[0039] Please see Figure 5 Unlike the manual replenishment described above, this embodiment has a replenishment pipe 11 installed at the top of the inlet pipe 505. The end of the replenishment pipe 11 away from the inlet pipe 505 is connected to the storage tank, and a valve 12 is installed on the side wall of the replenishment pipe 11. This valve 12 can be a model G60 series solid-state relay + electric regulating valve (such as SAMSON 3820). A liquid level sensor 13 is installed at the top of the storage box 501. A Honeywell UDC series ultrasonic sensor (such as UDC3000) can be selected. The top of the sealing member 503 is connected to an electric telescopic rod 14 via a connecting rod. The tail end of the electric telescopic rod 14 is installed on the support frame on the storage box 501. By activating the electric telescopic rod 14, both sealing members 503 can be pulled upwards simultaneously to drain the liquid. A controller 15 is installed on the support frame. The recommended model is STM32F103RCT6. The microcontroller 15 is used to receive electrical or digital signals from the sensor and then send a signal to the valve 12 to control the opening and closing of the valve 12. When the liquid level sensor 13 detects that the solution in the liquid storage box 501 is full, it sends a signal to the controller 15. The controller 15 controls the valve 12 to close and stop replenishing the solution. When the liquid level sensor 13 detects that the solution in the liquid storage box 501 is empty, it sends a signal to the controller 15 to control the valve 12 to open and replenish the solution.

[0040] In practical use, the solution is added to the inside of the storage box 501 through the inlet pipe 505 at the top of the storage box 501. The storage box 501 is a transparent plate with graduation lines. When the appropriate amount is added, the sealing part 503 can be removed to drain the liquid. In case of emergency, the solution can also be replenished through the graduation lines on the storage box 501. Compared with adding directly to the inner cavity of the inner cylinder 2, it has a greater margin of error. During the crystallization process, the stirring rod 4 can be rotated by starting the motor 3 to speed up the mixing of the solution. After the crystallization is completed, the hydraulic rod 602 is started to move the sealing plate 601 out of the discharge port. The crystals are discharged from the inner cylinder 2 and slide out of the outer cylinder 1 through the discharge port 703 along the top plate 702, finally completing the crystallization process.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
