However, this structure is not easy to quickly transport the medium for crystallization and is not easy to separate the crystalline medium during use, and it is not convenient enough during use. Summary of the Invention

[0004] In order to overcome the above - mentioned defects of the prior art, the present invention provides a scale - preventing evaporation crystallization device, aiming to solve the problems raised in the above - mentioned background art.

[0005] The present invention provides the following technical solutions: A scale - preventing evaporation crystallization device includes an evaporation furnace, and a diversion crystallization assembly is arranged on the evaporation furnace; The diversion crystallization assembly includes an evaporation chamber arranged at the top of the evaporation furnace. A crankshaft is rotatably connected to the middle of the evaporation furnace. Two stirring plates for stirring are installed on the crankshaft through bolts, and a traction rod sleeved on the surface of the crankshaft is arranged between the two stirring plates. A sealing sleeve is sleeved on the outer side of the traction rod; The top end of the towing bar is hinged with a towing block. The top of the sealing sleeve is fixedly provided with a supercharging cylinder. One side of the surface of the supercharging cylinder is provided with a first crystallization chamber. One side of the first crystallization chamber is installed with a second crystallization chamber by bolts. Pressure relief valves are arranged on one side of the surfaces of the first crystallization chamber and the second crystallization chamber; One side of the inner wall of the supercharging cylinder is provided with a diversion cavity. The middle of the first crystallization chamber is provided with a diversion cavity. A first slider is slidably connected between the first crystallization chamber and the second crystallization chamber. One side of the first slider is fixedly provided with a filter plate. The top of the towing block is installed with a piston rod by bolts. The outer side of the piston rod is slidably connected with a connecting disk. A number of through holes all communicating with the supercharging cylinder are penetrated through the connecting disk. The connecting disk is installed at the top end of the sealing sleeve by bolts. One end of the crankshaft is fixedly provided with a first eccentric disk. One side of the first eccentric disk is provided with a second eccentric disk. The second eccentric disk is fixed at the end of the crankshaft. The second eccentric disk and the first eccentric disk are rotationally connected to the evaporation furnace. Two ejector rods respectively abutted against the outer sides of the first eccentric disk and the second eccentric disk are inserted into the evaporation furnace. The top ends of the two ejector rods are both hinged with a first arc plate. The middle of the first arc plate is slidably connected with a second slider. The second slider is hinged with a first sliding rod. The first sliding rod penetrates through the first crystallization chamber and extends to the first slider. The first slider is installed on the first sliding rod by bolts. The first sliding rod is slidably connected with the first crystallization chamber. A crystallization plate for receiving crystals is embedded in the second crystallization chamber. The crystallization plate is detachably connected with the second crystallization chamber by bolts; It can be seen that in the above technical solution, the crankshaft drives the stirring plate to rotate to stir the medium in the evaporation furnace. The medium can be vaporized by heating in the evaporation cavity and conveyed into the supercharging cylinder through the through holes. At the same time, when the crankshaft rotates, it can also drive the towing block and the piston rod to displace in the supercharging cylinder through the towing bar, so that the vaporized medium can be conveyed into the supercharging cylinder through the through holes, realizing the function of extracting and conveying the vaporized medium. The vaporized medium is conveyed in the supercharging cylinder through the diversion cavity. At the same time, when the crankshaft rotates, it can also drive the second eccentric disk and the first eccentric disk to rotate. When the first eccentric disk and the second eccentric disk rotate, they can abut against the bottom ends of the ejector rods, and then the ejector rods can drive the first arc plate to displace and enable the first arc plate to rotate along the axis point of the connection of the ejector rod installed on the outer side of the second eccentric disk, so that the angle of the first arc plate can be adjusted, and then the second slider can displace; Optionally, in a possible implementation, the towing bar is rotatably connected to the crankshaft. The towing block is located in the middle of the sealing sleeve and is slidably connected to the sealing sleeve. One side of the bottom of the second crystallization chamber is fixedly provided with a second arc plate. A second sliding rod is slidably connected to the second arc plate. One end of the second sliding rod is hinged with a limiting rod. The bottom of the limiting rod is hinged with a supporting arc rod. The supporting arc rod is installed on one side of the evaporation furnace by bolts. An L-shaped rod slidably connected to the first arc plate is hinged to the limiting rod. A driving motor is installed on one side of the surface of the evaporation furnace by bolts. The output end of the driving motor extends to the end of the crankshaft and is detachably connected to the crankshaft by bolts; It can be seen that in the above technical solution, when the second slider displaces, it can push the first sliding rod to drive the first slider and the filter plate to displace between the second crystallization chamber and the first crystallization chamber, so that the filter plate can contact different positions of the diversion cavity and block the diversion cavity. It is convenient for the atomized medium in the first crystallization chamber and the second crystallization chamber to be transported to the crystallization plate for crystallization while the excess medium can flow back to the pressurizing cylinder through the diversion cavity. At the same time, when the piston rod displaces in the pressurizing cylinder, the gasified medium is pressurized and transported. The excess gasified medium is extracted through the diversion cavity and flows back to the pressurizing cylinder, which is conducive to the evaporation and gasification medium in the first crystallization chamber and the second crystallization chamber to crystallize on the crystallization plate, improving the crystallization efficiency and effect. And when the first arc plate deflects, it can also drive the L-shaped rod to displace, and then make the limiting rod deflect on the supporting arc rod, while the second sliding rod can guide and limit the limiting rod when it deflects, thus realizing the functions of positioning and guiding the first arc plate and ensuring the stability of the first arc plate when it deflects.

[0006] The technical effects and advantages of the present invention: 1. The present invention drives the stirring plate to rotate through the crankshaft to stir the medium in the evaporation furnace. The medium can be gasified by heating in the evaporation cavity and transported to the pressurizing cylinder through the through holes. At the same time, when the crankshaft rotates, it can also drive the towing block and the piston rod to displace in the pressurizing cylinder through the towing bar, so that the gasified medium can be transported to the pressurizing cylinder through the through holes, realizing the function of extracting and transporting the gasified medium, so as to facilitate the evaporation and crystallization of the medium; 2. When the second slider of the present invention displaces, it can push the first sliding rod to drive the first slider and the filter plate to displace between the second crystallization chamber and the first crystallization chamber, so that the filter plate can contact different positions of the diversion cavity and block the diversion cavity. It is convenient for the atomized medium in the first crystallization chamber and the second crystallization chamber to be transported to the crystallization plate for crystallization while the excess medium can flow back to the pressurizing cylinder through the diversion cavity, ensuring the crystallization quality and efficiency; 3. When the piston rod of the present invention displaces in the pressurizing cylinder, it pressurizes and transports the gasified medium. The excess gasified medium is extracted through the diversion cavity and flows back to the pressurizing cylinder, which is conducive to the evaporation and gasification medium in the first crystallization chamber and the second crystallization chamber to crystallize on the crystallization plate, improving the crystallization efficiency and effect; In summary, through the corresponding cooperation of each structure, when the crankshaft rotates, it drives the traction block and the piston rod to displace in the pressurization cylinder via the traction rod, so that the gasification medium is transported into the pressurization cylinder through the through hole, realizing the function of extracting and transporting the gasified medium. The first slide rod drives the first slider and the filter plate to displace between the second crystallization chamber and the first crystallization chamber, enabling the filter plate to contact the diversion chambers at different positions and block the diversion chambers, facilitating the crystallization of the atomized medium on the crystallization plate in the first crystallization chamber and the second crystallization chamber while the excess medium can flow back into the pressurization cylinder through the diversion chamber. When the piston rod displaces in the pressurization cylinder, it pressurizes and transports the gasification medium, and extracts the excess gasification medium through the diversion chamber to make it flow back into the pressurization cylinder, which is conducive to the evaporation and gasification medium in the first crystallization chamber and the second crystallization chamber to crystallize on the crystallization plate, improving the crystallization efficiency and effect.

On one side of the first slider 13, there is a filter plate 14 fixedly provided. On the top of the draw block 7, there is a piston rod 15 installed through bolts. The piston rod 15 is slidingly connected with a connecting disk 16 on the outside. Through holes 17 that are all communicated with the pressure increasing cylinder 8 are penetrated through the connecting disk 16. The connecting disk 16 is installed on the top end of the sealing sleeve 6 through bolts. One end of the crankshaft 3 is fixedly provided with a first eccentric disk 19. On one side of the first eccentric disk 19, there is a second eccentric disk 20. The second eccentric disk 20 is fixed at the end of the crankshaft 3. The second eccentric disk 20 and the first eccentric disk 19 are rotationally connected with the evaporation furnace 1. Two ejector rods 21 that respectively abut against the outside of the first eccentric disk 19 and the second eccentric disk 20 are inserted into the evaporation furnace 1. At the top ends of the two ejector rods 21, there is a first arc plate 22 hinged. In the middle of the first arc plate 22, there is a second slider 23 slidingly connected. On the second slider 23, there is a first sliding rod 24 hinged. The first sliding rod 24 penetrates through the first crystallization chamber 9 and extends to the first slider 13. The first slider 13 is installed on the first sliding rod 24 through bolts. The first sliding rod 24 is slidingly connected with the first crystallization chamber 9. A crystallization plate for receiving crystals is embedded in the second crystallization chamber 10. The crystallization plate is detachably connected with the second crystallization chamber 10 through bolts; The drawbar 5 is rotationally connected with the crankshaft 3. The draw block 7 is located in the middle of the sealing sleeve 6 and is slidingly connected with the sealing sleeve 6. On one side of the bottom of the second crystallization chamber 10, there is a second arc plate 25 fixedly provided. On the second arc plate 25, there is a second sliding rod 26 slidingly connected. One end of the second sliding rod 26 is hinged with a limiting rod 27. At the bottom of the limiting rod 27, there is a supporting arc rod 28 hinged. The supporting arc rod 28 is installed on one side of the evaporation furnace 1 through bolts. On the limiting rod 27, there is an L-shaped rod 30 hinged with the first arc plate 22 and slidingly connected. On one side of the surface of the evaporation furnace 1, there is a driving motor 29 installed through bolts. The output end of the driving motor 29 extends to the end of the crankshaft 3 and is detachably connected with the crankshaft 3 through bolts.

[0018] During use according to the above structure, the staff installs the device at a designated position, adds the medium into the evaporation furnace 1, and drives the crankshaft 3 by the drive motor 29 to drive the stirring plate 4 to rotate to stir the medium in the evaporation furnace 1. The medium can be vaporized by heating in the evaporation chamber 2 and transported to the pressurizing cylinder 8 through the through hole 17. At the same time, when the crankshaft 3 rotates, it can also drive the traction block 7 and the piston rod 15 to displace in the pressurizing cylinder 8 through the traction rod 5, so that the vaporized medium can be transported to the pressurizing cylinder 8 through the through hole 17, realizing the function of extracting and transporting the vaporized medium; Further, during the up and down displacement of the piston rod 15, the leather pad installed thereon is used to block the medium. When moving downward, the leather pad opens, and when moving upward, the leather pad is closely attached to the piston rod 15 for sealing due to the pressure, which is convenient for extracting and transporting the medium; The vaporized medium is transported through the diversion chamber 11 in the pressurizing cylinder 8. At the same time, when the crankshaft 3 rotates, it can also drive the second eccentric disk 20 and the first eccentric disk 19 to rotate. When the first eccentric disk 19 and the second eccentric disk 20 rotate, they can contact the bottom end of the ejector rod 21. Since the first eccentric disk 19 and the second eccentric disk 20 rotate synchronously but have different eccentric positions, when the second eccentric disk 20 rotates, it drives the ejector rod 21 thereon downward, and when the first eccentric disk 19 rotates, it drives the ejector rod 21 thereon upward, so that the two ejector rods 21 can form a height difference, and then the first arc plate 22 can rotate along the central point of the connection between the ejector rod 21 installed on the second eccentric disk 20 and it, so that the angle of the first arc plate 22 can be adjusted, and then the second slider 23 can displace; When the second slider 23 displaces, it can push the first slide rod 24 to drive the first slider 13 and the filter plate 14 to displace between the second crystallization chamber 10 and the first crystallization chamber 9, so that the filter plate 14 can contact different diversion chambers 12 and block the diversion chambers 12, which is convenient for the atomized medium in the first crystallization chamber 9 and the second crystallization chamber 10 to be transported to the crystallization plate for crystallization while the excess medium can flow back to the pressurizing cylinder 8 through the diversion chamber 11; And while the piston rod 15 displaces in the pressurizing cylinder 8, it pressurizes and transports the vaporized medium, and extracts the excess vaporized medium through the diversion chamber 11 to make it flow back to the pressurizing cylinder 8, which is convenient for the evaporation and vaporization medium in the first crystallization chamber 9 and the second crystallization chamber 10 to crystallize on the crystallization plate, improving the crystallization efficiency and effect; And when the first arc plate 22 deflects, it can also drive the L rod 30 to displace, and then the limit rod 27 deflects on the support arc rod 28, and the second slide rod 26 can guide and limit the deflection of the limit rod 27, and then realize the functions of positioning and guiding the first arc plate 22, ensuring the stability when the first arc plate 22 deflects; Moreover, the crystallization plate is detachably connected to the second crystallization chamber 10 by bolts, and can be disassembled and replaced after crystallization. During the up-and-down displacement of the filter plate 14, the first slider 13, and the piston rod 15 in displacement, the filter plate 14 and the first slider 13 rub against the inner wall of the second crystallization chamber 10, while the piston rod 15 rubs against the inner wall of the pressure increasing cylinder 8, which is conducive to cleaning the medium adhering to the inner walls of the second crystallization chamber 10 and the pressure increasing cylinder 8 and reducing the occurrence of dirt.

[0019] Different from the prior art, the present application discloses an anti-scaling evaporation crystallization device. When the crankshaft 3 rotates, it drives the traction block 7 and the piston rod 15 to displace in the pressure increasing cylinder 8 through the traction rod 5, so that the vaporized medium can be transported into the pressure increasing cylinder 8 through the through hole 17, realizing the function of extracting and transporting the vaporized medium. The first sliding rod 24 drives the first slider 13 and the filter plate 14 to displace between the second crystallization chamber 10 and the first crystallization chamber 9, so that the filter plate 14 can contact different positions of the shunt cavity 12 and block the shunt cavity 12, facilitating the crystallization of the atomized medium in the first crystallization chamber 9 and the second crystallization chamber 10 on the crystallization plate while the excess medium can flow back into the pressure increasing cylinder 8 through the diversion cavity 11. When the piston rod 15 displaces in the pressure increasing cylinder 8, it pressurizes and transports the vaporized medium, and extracts the excess vaporized medium through the diversion cavity 11 to make it flow back into the pressure increasing cylinder 8, which is conducive to the evaporation and vaporization medium in the first crystallization chamber 9 and the second crystallization chamber 10 to crystallize on the crystallization plate, improving the crystallization efficiency and effect.
