Description

Technical Field

[0001] This utility model relates to the field of crystallization, and in particular to a cooling crystallization apparatus. Background Technology

[0002] A cooling crystallization device is a device used to cool a solution and promote the crystallization of a solute. Its main function is to control the crystallization process of the solute by adjusting parameters such as temperature, solution concentration, and stirring speed, so as to achieve separation, purification, or other purposes.

[0003] In the production process of perchloric acid, the perchloric acid solution is usually supersaturated. By feeding the solution into a tank and then cooling it, the perchloric acid precipitates out as crystals. A motor drives a stirring plate on a stirring rod to rotate, causing the solution to flow and cool more evenly. During crystallization, the crystals tend to adhere to the inner wall of the tank, hindering subsequent removal and thus affecting the effectiveness of the cooling and crystallization equipment. Utility Model Content

[0004] The technical problem this invention aims to solve is that during the crystallization of perchloric acid solution, the crystals tend to adhere to the inner wall of the tank, which affects the subsequent removal of the crystals and thus impacts the effectiveness of the cooling crystallization device.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a cooling crystallization device for perchloric acid production, including a tank body, a motor at the upper end of the tank body, a stirring rod inside the tank body, several stirring plates on one side of the stirring rod, and a cleaning device on the side of the stirring plate near the inner wall of the tank body, the cleaning device cleaning the inner wall of the tank body by means of a scraper.

[0006] The effects achieved by the above components are as follows: In the production process of perchloric acid, the perchloric acid solution is usually supersaturated. By sending the solution into the tank and then cooling the solution, the perchloric acid in the solution can precipitate out of the solution to form crystals. The motor drives the stirring plate on the stirring rod to rotate, so that the solution flows and the solution is cooled more evenly. The stirring plate also drives the cleaning device to clean the inner wall of the tank.

[0007] Preferably, the stirring plate is provided with a fixing component on the side near the inner wall of the tank, and the stirring plate is provided with a cleaning device by means of the fixing component. The cleaning device includes a placement plate, a spring and a scraper. The placement plate is located on the side of the stirring plate near the inner wall of the tank. The spring is connected to the scraper and the placement plate. One side of the scraper is in contact with the inner wall of the tank.

[0008] The effect achieved by the above components is as follows: When the fixing assembly fixes the cleaning device to the side of the stirring plate near the inner wall of the tank, the spring fixed on one side of the plate and in a compressed state will reset and drive the scraper fixed on one side to contact the inner wall of the tank. Then the scraper will rotate with the stirring plate and clean and remove the crystals adhering to the inner wall of the tank. When the scraper surface is worn, the compressed spring will continue to reset, and the scraper surface will still be in close contact with the inner wall of the tank. By using the cleaning device, the crystals adhering to the inner wall of the tank can be scraped and cleaned, avoiding the situation that will affect the subsequent removal of crystals from the tank, thereby improving the performance of the cooling crystallization device.

[0009] Preferably, a telescopic rod is sleeved inside the spring, and both ends of the telescopic rod are connected to the placement plate and the scraper. The telescopic rod restricts the shape of the spring.

[0010] The effect achieved by the above components is as follows: by fixing the two ends of the telescopic rod to the placement plate and the scraper, and with the telescopic rod inside the spring, the shape of the spring is restricted, thus preventing the spring from bending and affecting its return to its original position.

[0011] Preferably, one side of the placement plate is provided with a plurality of anti-slip blocks, which increase the friction on one side of the placement plate.

[0012] The effect achieved by the above components is to increase the friction on one side of the placement plate by fixing it with several anti-slip blocks, thereby making the placement plate easier to hold and move.

[0013] Preferably, a through hole is provided on one side of the placement plate, and a stabilizing rod is provided on the side of the scraper near the placement plate, the stabilizing rod passing through the through hole on one side of the placement plate.

[0014] The effect achieved by the above components is as follows: the stabilizing rod is fixed to the scraper, and the stabilizing rod slides through the through hole on one side of the placement plate, so that the scraper can move more stably and avoid the scraper changing position after being subjected to force, which would affect the use of the scraper.

[0015] Preferably, the fixing assembly includes a bolt and a fixing plate. The bolt is inserted into the side of the stirring plate near the inner wall of the tank. The bolt passes through the fixing plate and is connected to the stirring plate to fix the position of the fixing plate. One side of the fixing plate is connected to the placement plate.

[0016] The effect achieved by the above components is as follows: by contacting the fixing plate with the mixing plate near the inner wall of the tank, and then rotating the bolt, the bolt passes through the fixing plate and is threadedly fixed to the mixing plate, thus completing the quick installation and fixing of the placement plate. When disassembling the cleaning device, the bolt is separated from the mixing plate, thus quickly completing the disassembly of the cleaning device. By using the fixing components, the cleaning device can be quickly installed and removed from the surface of the mixing plate, thus facilitating the use and replacement of the cleaning device.

[0017] Preferably, a positioning block is provided on one side of the stirring plate, and the positioning block positions the fixing plate.

[0018] The effect achieved by the above components is to quickly position the fixed plate and the mixing plate by fixing them together with the positioning block, so that the operator can then use bolts to fix the fixed plate.

[0019] Preferably, a reinforcing plate is provided on one side of the fixing plate, and the reinforcing plate enhances the connection strength between the fixing plate and the placement plate.

[0020] The effect achieved by the above components is to improve the connection strength between the reinforcing plate, the fixing plate, and the placement plate by fixing them together, thereby preventing deformation at the connection point.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] By using a cleaning device, crystals adhering to the inner wall of the tank can be scraped off and cleaned, avoiding any impact on the subsequent removal of crystals from the tank, thereby improving the performance of the cooling crystallization device.

[0023] By using a fixing component, the cleaning device can be quickly installed and removed from the surface of the mixing plate, making it convenient to use and replace the cleaning device. Attached Figure Description

During the perchloric acid production process, the perchloric acid solution is usually supersaturated. By feeding the solution into the tank 1 and then cooling it, the perchloric acid in the solution can precipitate out to form crystals. The motor 2 drives the agitator plates 4 on the agitator 3 to rotate, causing the solution to flow and cool more evenly. The agitator plates 4 also drive the cleaning device 5 to clean the inner wall of the tank 1.

One side of the scraper 53 is in contact with the inner wall of the tank 1. When the fixing component 6 fixes the cleaning device 5 to the stirring plate 4 near the inner wall of the tank 1, the spring 52, which is fixed on one side of the plate 51 and is in a compressed state, will reset and drive the scraper 53 fixed on one side to contact the inner wall of the tank 1. Then the scraper 53 will rotate with the stirring plate 4 and clean and remove the crystals adhering to the inner wall of the tank 1. When the surface of the scraper 53 is worn, the compressed spring 52 will continue to reset, and the surface of the scraper 53 will still be in close contact with the inner wall of the tank 1. By using the cleaning device 5, the crystals adhering to the inner wall of the tank 1 can be scraped and cleaned, avoiding the situation that affects the subsequent removal of crystals from the inside of the tank 1, thereby improving the performance of the cooling crystallization device.

[0034] Figures 1 to 4 The spring 52 shown has a telescopic rod 54 inside, with both ends of the telescopic rod 54 connected to the placement plate 51 and the scraper 53. The telescopic rod 54 restricts the shape of the spring 52. By fixing both ends of the telescopic rod 54 to the placement plate 51 and the scraper 53, and by placing the telescopic rod 54 inside the spring 52, the shape of the spring 52 is restricted, preventing the spring 52 from bending and affecting its return to its original position. Several anti-slip blocks 55 are provided on one side of the placement plate 51, increasing the friction on one side of the placement plate 51. By fixing the anti-slip blocks 55 to the placement plate 51, the friction on one side of the placement plate 51 is increased, making it easier to hold and move the placement plate 51. A through hole 56 is opened on one side of the placement plate 51, and a stabilizing rod 57 is provided on the scraper 53 near the side of the placement plate 51, passing through the through hole 56 on one side of the placement plate 51. The stabilizing rod 57 is fixed to the scraper 53, and the stabilizing rod 57 slides with the through hole 56 on one side of the placement plate 51, so that the scraper 53 can move more stably, avoiding the situation where the scraper 53 changes position after being subjected to force, thus affecting the use of the scraper 53.

The bolt 61 passes through the fixing plate 62 and is connected to the stirring plate 4 to fix the position of the fixing plate 62. One side of the fixing plate 62 is connected to the placement plate 51. By contacting the side of the stirring plate 4 near the inner wall of the tank 1 with the fixing plate 62, and then rotating the bolt 61, the bolt 61 passes through the fixing plate 62 and is threadedly fixed to the stirring plate 4, thus completing the quick installation and fixing of the placement plate 51. When disassembling the cleaning device 5, the bolt 61 is separated from the stirring plate 4, thus quickly completing the disassembly of the cleaning device 5. By using the fixing component 6, the cleaning device 5 can be quickly installed and removed from the surface of the stirring plate 4, making it convenient to use and replace the cleaning device 5.

[0036] Figures 1 to 4 A positioning block 63 is provided on one side of the stirring plate 4, which positions the fixing plate 62. The positioning block 63, fixed to the stirring plate 4, allows for quick positioning of the fixing plate 62, facilitating subsequent fixation of the fixing plate 62 using bolts 61. A reinforcing plate 64 is provided on one side of the fixing plate 62, which enhances the connection strength between the fixing plate 62 and the placement plate 51. The reinforcing plate 64, fixed to both the fixing plate 62 and the placement plate 51, strengthens the connection and prevents deformation at the connection point.

[0037] Working principle: In the production process of perchloric acid, the perchloric acid solution is usually supersaturated. By sending the solution into the tank 1 and then cooling the solution, the perchloric acid in the solution can precipitate out of the solution to form crystals. The motor 2 drives the stirring plate 4 on the stirring rod 3 to rotate, so that the solution flows and the solution is cooled more evenly. The stirring plate 4 drives the cleaning device 5 to clean the inner wall of the tank 1. When the fixing component 6 fixes the cleaning device 5 to the stirring plate 4 near the inner wall of the tank 1, the spring 52, which is fixed on one side of the plate 51 and is in a compressed state, will reset and drive the scraper 53 fixed on one side to contact the inner wall of the tank 1. Then the scraper 53 will rotate with the stirring plate 4 and clean and remove the crystals adhering to the inner wall of the tank 1. When the surface of the scraper 53 is worn, the compressed spring 52 will continue to reset, and the surface of the scraper 53 will still be in close contact with the inner wall of the tank 1. By using the cleaning device 5, the crystals adhering to the inner wall of the tank 1 can be scraped and cleaned, avoiding the situation that affects the subsequent removal of crystals from the inside of the tank 1, thereby improving the performance of the cooling crystallization device.

[0038] By contacting the fixing plate 62 with the stirring plate 4 near the inner wall of the tank 1, and then rotating the bolt 61, the bolt 61 passes through the fixing plate 62 and is threadedly fixed to the stirring plate 4, thus completing the quick installation and fixing of the placement plate 51. When disassembling the cleaning device 5, the bolt 61 is separated from the stirring plate 4, thus quickly completing the disassembly of the cleaning device 5. By using the fixing component 6, the cleaning device 5 can be quickly installed and removed from the surface of the stirring plate 4, thus facilitating the use and replacement of the cleaning device 5.
