For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.
[0028] Example 1, please refer to Figures 1 to 4 The present invention provides a technical solution: an automated and precise temperature-controlled crystallizer device, comprising a crystallizer body 1 and a filter component. Multiple support legs 3 are fixedly installed on the crystallizer body 1, and a feed pipe 6 is fixedly installed on the bottom wall of the crystallizer body 1, and the feed pipe 6 is connected to the interior of the crystallizer body 1.
[0029] The crystallization tank body 1 is used to hold the material to be crystallized and provides space for the installation and operation of other components. The support legs 3 are used to support the entire device (specifically the crystallization tank body 1), ensuring that it is placed stably on the ground and preventing the device from tilting or shaking due to uneven ground, which would affect the normal progress of the crystallization process.
[0030] The filtering component includes a first collecting hopper 10, a cylinder 7, a second collecting hopper 12, and a driving assembly. A first support plate 9 and a second support plate 11 are fixedly installed at both ends of the first collecting hopper 10, respectively. The side wall of the second support plate 11 away from the first collecting hopper 10 is fixedly connected to the second collecting hopper 12. The cylinder 7 is installed on the upper part of the first support plate 9 and the second support plate 11 (in this embodiment, the cylinder 7 is fixedly installed on the first support plate 9 and the second support plate 11), and the cylinder 7 is located above the first collecting hopper 10. Numerous filter holes 14 are opened on the lower cylinder wall of the cylinder 7. The lower end of the discharge pipe 6 above the second collecting hopper 12 of the cylinder 7 penetrates the cylinder wall of the cylinder 7, and the discharge pipe 6 communicates with the interior of the cylinder 7.
[0031] The first collecting hopper 10 is used to collect impurities that fall during the filtration process. A first support plate 9 and a second support plate 11 are fixedly installed at both ends of the hopper to provide support for the installation and stable operation of the filtration components. Numerous filter holes 14 are provided on the lower wall of the cylinder 7 to filter impurities from the crystallization process. The second collecting hopper 12 is used to collect the purified crystals after filtration. Its position is rationally designed to ensure smooth discharge of the crystals for subsequent processing.
[0032] The drive assembly includes a second motor 8, a spiral conveying rod 13, and a connecting plate 18. The second motor 8 is fixedly mounted on the first support plate 9. The spiral conveying rod 13 is rotatably mounted inside the cylinder 7. The output shaft end of the second motor 8 is coaxially and fixedly connected to one end of the spiral conveying rod 13. The connecting plate 18 is fitted on the outer wall of the spiral conveying rod 13 near the second motor 8 and the two are fixedly connected. The outer periphery of the connecting plate 18 abuts against the edge of the cylinder 7 near the first support plate 9.
[0033] The second motor 8 provides power to the drive assembly. Its output shaft rotation drives the spiral conveyor 13 to rotate, thus conveying and agitating the crystals and improving filtration efficiency. The rotation of the spiral conveyor 13 transports the crystals towards the side where the second collection hopper 12 is located. Simultaneously, the fixing rod 19 on the spiral blades further agitates the crystals, causing impurities to fall through the filter holes into the first collection hopper 10, improving the filtration effect. The connecting plate 18 acts as a barrier at one end of the cylinder 7 to prevent material from falling. Material inside the crystallizer body 1 enters the cylinder 7 through the feed pipe 6. After the second motor 8 starts, its output shaft drives the spiral conveyor 13 to rotate. The spiral conveyor 13 then drives the connecting plate 18 to rotate. As the spiral conveyor 13 rotates, it moves the material inside the cylinder 7. During this movement, impurities in the material fall through the filter holes 14 on the cylinder 7 into the first collection hopper 10, while the crystallized material inside the cylinder 7 falls into the second collection hopper 12 under the push of the spiral conveyor 13.
[0034] Specifically, a top cover 2 is detachably installed on the main body 1 of the crystallization tank. A stirring component is provided on the top cover 2. The stirring component includes a first motor 4 and a stirring rod 16. The first motor 4 is fixedly installed on the top cover 2, and the stirring rod 16 is rotatably installed on the top cover 2. The output shaft of the first motor 4 passes through the top cover 2, and the output shaft of the first motor 4 is coaxially and fixedly connected to the stirring rod 16.
[0035] The top cover 2 serves to seal and protect the crystallizer body 1, preventing external impurities from entering and providing a mounting position for the stirring components and the feed pipe 5. The first motor 4 provides power to the stirring components, and the rotation of its output shaft drives the stirring rod 16 to rotate, thereby stirring the material inside the crystallizer body 1, ensuring uniform heating of the material, and accelerating the crystallization process.
[0036] More specifically, the stirring component also includes a temperature sensor 17, which is fixedly mounted on the stirring rod 16. The automated, precise temperature-controlled crystallizer device shown in this technical solution also includes a control board in its implementation. The control board houses a control system, and may include, but is not limited to, a programmable logic controller. The control board is communicatively connected (including electrically connected) to the temperature sensor 17. An annular cavity is formed on the side wall of the crystallizer body 1, and a heating element 15 is fixedly installed in the annular cavity of the crystallizer body 1.
[0037] The temperature sensor 17 is used to monitor the temperature inside the crystallizer body 1 in real time. It converts the temperature signal into an electrical signal and transmits it to the control system on the control board. The control system automatically adjusts the power of the heating element 15 based on the feedback signal, achieving precise temperature control during the crystallization process. The heating element 15 uses existing heating components such as heating wires. In practice, components such as fuses and temperature controllers are also needed to assist the heating element 15 in its implementation, to meet the needs of heating and temperature control. These details will not be elaborated here. The heating element 15 is used to heat the material inside the crystallizer body 1. Its heating power can be automatically adjusted according to the feedback signal from the temperature sensor 17, ensuring that the crystallization process takes place within the set temperature range, thereby improving product quality and consistency.
[0038] More specifically, a feed pipe 5 is fixedly installed on the upper cover 2, and control valves are installed on both the feed pipe 5 and the discharge pipe 6 of the upper cover 2.
[0039] The feed pipe 5 is used to introduce the material to be crystallized into the crystallization tank body 1. A control valve installed on it precisely controls the material flow rate to ensure that the material input meets process requirements. The discharge pipe 6 is used to discharge the crystallized material. Its lower end penetrates the wall of the cylinder 7 and communicates with the interior of the cylinder 7, allowing the material to smoothly enter the filter element for impurity separation. The control valve on the discharge pipe 6 controls the material discharge speed to prevent insufficient filtration due to excessive material discharge; simultaneously, this control valve controls the opening and closing of the discharge pipe 6.
[0040] Specifically, the spiral conveyor 13 is composed of a rotating rod and a spiral blade. One end of the rotating rod is fixedly connected to the output shaft end of the second motor 8. The spiral blade is fitted on the outer side wall of the rotating rod and the two are fixedly connected. A fixing rod 19 is fixedly connected to each spiral side wall of the spiral blade.
[0041] When the second motor 8 starts, its output shaft drives the rotating rod to rotate, which in turn drives the spiral blades to rotate. The spiral blades then move the material inside the cylinder 7. As the spiral blades rotate, they also drive the fixed rod 19 to rotate. The fixed rod 19 can turbulently agitate the material inside the cylinder 7, thus enhancing the material filtration effect.
[0042] In operation, the material to be crystallized is first introduced into the crystallization tank body 1 through the feed pipe 5. The first motor 4 is started, driving the stirring rod 16 to rotate and stir the material, ensuring uniform heating. Simultaneously, the heating element 15 begins operation, heating the material within the crystallization tank body 1. The temperature sensor 17 monitors the temperature within the crystallization tank body 1 in real time and transmits the temperature signal to the control system. The control system automatically adjusts the power of the heating element 15 based on the feedback signal, ensuring the crystallization process occurs within the set temperature range, achieving precise temperature control.
[0043] After crystallization, the control valve on the feed pipe 6 is opened, allowing the crystallized material to enter the cylinder 7 through the feed pipe 6. The second motor 8 is started, driving the screw conveyor 13 to rotate. The rotation of the screw conveyor 13 causes the crystals to be conveyed to the right, while the fixing rod 19 on the screw blades further agitates the crystals, allowing impurities to come into more thorough contact with the filter screen. During the rightward conveying of the crystals, impurities fall through the filter screen 14 into the first collection hopper 10, achieving impurity separation. The pure crystals are finally discharged through the port on the right side of the cylinder 7 and enter the second collection hopper 12 for collection.
[0044] Example 2, please refer to Figures 5 to 6 The main difference between this embodiment and Embodiment 1 is that: one end of the cylinder 7 passes through the second support plate 11 and the two are laterally slidably connected; a fixing block 24 is fixedly connected to the outer wall of the cylinder 7; a spring 23 is fixedly connected to one side wall of the fixing block 24; and the end of the spring 23 away from the fixing block 24 is fixedly connected to the second support plate 11. A first protrusion 20 is fixedly connected to the side wall of the connecting plate 18 near the cylinder 7; and a second protrusion 21 is fixedly connected to the edge of the end of the cylinder 7 near the connecting plate 18. When the connecting plate 18 drives the first protrusion 20 to rotate, the first protrusion 20 abuts against the second protrusion 21.
[0045] When the screw conveyor rod 13 rotates, it drives the connecting plate 18 to rotate. The connecting plate 18 then drives the first protrusion 20 to rotate. As the first protrusion 20 rotates, it collides with the second protrusion 21, pushing the second protrusion 21 to move away from the first protrusion. The second protrusion 21 then causes the cylinder 7 to slide on the second support plate 11. When the first protrusion 20 passes the second protrusion 21, the spring 23, under its elastic action, pushes the cylinder 7 back to its original position. During this process, the cylinder 7 is in a lateral reciprocating swaying state. This design further enhances the material agitation effect, allowing impurities to come into more thorough contact with the filter screen and improving filtration efficiency.
[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
