[0002] Optical glass is a special glass material with excellent optical properties and characteristics. During the production process of optical glass, after being treated with potassium nitrate, its flexural strength, surface hardness and other properties are improved, making the optical glass more durable during use. And potassium nitrate needs to go through the steps of crystallization and purification during the preparation process to improve the purity of potassium nitrate, so that its effect in glass production is better.

[0003] In the existing potassium nitrate purification process, a closed crystallization tank body is required to complete the crystallization process of potassium nitrate inside the tank body, and then the crystallized potassium nitrate of this batch is collected. This type of crystallization and purification method makes the preparation efficiency of potassium nitrate slower, and only a fixed amount can be processed at a time.

[0004] Moreover, the crystals are easily adhered to the inner wall of the kettle body inside the tank, affecting the efficiency of subsequent crystallization in the kettle.

[0005] Therefore, the inventor of the present invention has designed and developed a potassium nitrate purification device for glass production, which can perform continuous crystallization treatment of potassium nitrate and improve the preparation efficiency of its crystallization treatment.

By driving the rotation of the crystallization plate 3 inside the crystallization cylinder 1 by the support mechanism 2, when the crystallization plate 3 is at the bottom of the inner cavity of the crystallization cylinder 1, the solution at the bottom of the inner cavity of the crystallization cylinder 1 will come into contact with the surface of the crystallization plate 3. Utilizing the low temperature on the surface of the crystallization plate 3, the solution can crystallize and adhere to the surface of the crystallization plate 3. A pipe for discharging the internal solution is connected to the bottom of the crystallization cylinder 1. According to the connection function of the feed pipe 101, continuous solution supply can be carried out into the crystallization cylinder 1 according to the crystallization output situation of the solution at the bottom of the crystallization cylinder 1, so that the crystallization plate 3 can continuously crystallize the solution at the bottom of the inner cavity of the crystallization cylinder 1;

[0041] A pushing mechanism 4 is arranged inside the support mechanism 2 in the crystallization cylinder 1. The pushing mechanism 4 includes a driven roller 401 and a driving roller 402. A driven shaft 4011 is arranged on the driven roller 401. A driving shaft 4021 is arranged on the driving roller 402. A first bracket 4012 for installing the driven shaft 4011 is arranged inside the crystallization cylinder 1. A second bracket 4022 for installing the driving shaft 4021 is arranged outside the crystallization cylinder 1. When the driving shaft 4021 drives the driving roller 402 to rotate, through the setting of the conveyor belt 403, the driven shaft 4011 and the driven roller 401 can also rotate following the rotation of the driving roller 402, so as to enable the pushing component 404 to act on the top surface of the receiving plate 5. The first bracket 4012 and the second bracket 4022 respectively provide a fixing function for the connection between the driven roller 401 and the driving roller 402 and the crystallization cylinder 1, so that the pushing mechanism 4 can be installed inside the support mechanism 2, and when the support mechanism 2 drives the crystallization plate 3 to rotate, it will not affect the pushing mechanism 4.

[0042] Specifically, the support mechanism 2 includes a driving ring 201 rotatably sleeved with the discharge port 102. A connecting frame 202 for installing the crystallization plate 3 is arranged on the driving ring 201.

A driving motor 6 for driving the driving shaft 4021 to rotate is arranged on the second bracket 4022. The rotation of the driving roller 402 is provided by the rotation of the output shaft of the driving motor 6, so that the pushing component 404 can push out and collect the crystals after filtration treatment on the top surface of the receiving plate 5 through the discharge port 102 under the action of the conveyor belt 403.

[0044] Specifically, a side gear ring 21 is provided on the active ring 201, and a spur gear 61 meshing with the side gear ring 21 is provided on the active shaft 4021. The setting of the side gear ring 21 can mesh and match with the active shaft 4021, so that when the driving motor 6 drives the internal components of the material pushing mechanism 4 to rotate, the active shaft 4021 can synchronously drive the side gear ring 21 to rotate, thereby enabling the support mechanism 2 to drive the crystallization plate 3 to rotate inside the crystallization cylinder 1, so that the rotation of the crystallization plate 3 and the rotation of the internal components of the material pushing mechanism 4 can be synchronized.

[0045] Specifically, the material pushing component 404 includes a mounting frame 4041 connected to the conveyor belt 403, and a material pushing plate 4042 acting on the top surface of the material receiving plate 5 is provided on the mounting frame 4041. Through the setting of the material pushing component 404, after the crystals fall on the top surface of the material receiving plate 5 and then the excess solution in the crystals is filtered by the filtrate net 51, the material pushing plate 4042 can push the crystals on the top surface of the material receiving plate 5 to one end of the discharge port 102. According to the continuous movement of the internal components of the material pushing mechanism 4, the crystals can fall and be collected from the end of the material receiving plate 5 located at one end of the discharge port 102. When the material pushing plate 4042 moves, it can simultaneously scrape the top surface of the material receiving plate 5 and the inner side surface of the side baffle 52, so that no crystals adhere to the top surface of the material receiving plate 5 and the inner side surface of the side baffle 52, avoiding waste of crystals during transportation.

[0046] Specifically, a material receiving plate 5 is provided on the driven shaft 4011 and the active shaft 4021. A filtrate net 51 for filtering crystals is provided on the top surface of the material receiving plate 5, and side baffles 52 are provided on both sides of the material receiving plate 5. Through the setting of the material receiving plate 5, the crystals attached to the surface of the crystallization plate 3 can be caught by the material receiving plate 5 after falling from the top of the crystallization cylinder 1, and the excess solution mixed in the crystals will fall into the solution to be crystallized at the bottom of the inner cavity of the crystallization cylinder 1 through the filtrate net 51, avoiding waste of the solution.

[0047] Specifically, an adjustment box 7 is provided on the top surface of the crystallization cylinder 1, and a cross beam frame 71 is provided in the adjustment opening 103. Through the setting of the adjustment opening 103 and the adjustment box 7, it is convenient to replace the cross beam frame 71.

[0048] Specifically, a vertical frame 73 is provided at the bottom of the crossbeam frame 71, and a scraper strip 731 acting on the surface of the crystallization plate 3 is provided on the side of the vertical frame 73. Through the setting of the scraper strip 731, when the crystallization plate 3 rotates from the bottom of the inner cavity of the crystallization cylinder 1 to the top of the inner cavity of the crystallization cylinder 1, the scraper strip 731 will block the crystals attached to the surface of the crystallization plate 3, so that the crystals are separated from the surface of the crystallization plate 3, and the crystals can fall on the top surface of the receiving plate 5 by gravity, and a small part of the solution contaminated by the crystallization plate 3 will also drip onto the top surface of the receiving plate 5, and after being filtered by the filtrate net 51, the contaminated solution can fall into the solution to be treated on the inner bottom surface of the crystallization cylinder 1, effectively avoiding the waste of solution;

[0049] A hydraulic cylinder 72 is provided on the top surface of the regulating box 7, and the bottom end of the output shaft of the hydraulic cylinder 72 is fixedly connected to the top surface of the crossbeam frame 71. Through the arrangement of the hydraulic cylinder 72 and the strip cleaning mechanism 74, when there are a large number of crystals adhering to the surface of the scraper strip 731 due to cleaning the crystallization plate 3, the hydraulic cylinder 72 can control the vertical frame 73 to move upward, so that the scraper strip 731 can slide relative to the strip cleaning mechanism 74, so that the scraper strip 731 can move inside the strip cleaning notch 743, so that the strip cleaning frame 742 can clean the crystals attached to the surface of the scraper strip 731. After cleaning, the hydraulic cylinder 72 can control the vertical frame 73 to reset, so that the scraper strip 731 can act on the surface of the crystallization plate 3 again. Example 2

[0050] Reference Figures 1-12 The difference between this embodiment and embodiment 1 is that a strip clearing mechanism 74 is set in the regulating port 103, and the strip clearing mechanism 74 includes a hanger 741 connected to the top surface of the crystallization tube 1, and a strip clearing frame 742 is set at the bottom of the hanger 741. The strip clearing frame 742 is provided with a strip clearing notch 743 that is movably mounted with the scraper bar 731.

[0053] The support mechanism 2 drives the crystallization plate 3 to rotate inside the crystallization cylinder 1. When the crystallization plate 3 rotates to the bottom of the inner cavity of the crystallization cylinder 1, its surface contacts the solution, and the low temperature on the surface of the crystallization plate 3 is used to make the solution crystallize and adhere to the surface of the crystallization plate 3.

[0054] When the crystallization plate 3 rotates to the top of the inner cavity of the crystallization cylinder 1, the scraper strip 731 blocks the crystals attached to the surface of the crystallization plate 3, so that the crystals are separated from the surface of the crystallization plate 3 and fall on the top surface of the receiving plate 5;

[0055] The filtrate net 51 on the top surface of the receiving plate 5 filters the excess solution mixed in the crystals, so that the solution falls back into the solution to be crystallized at the bottom of the inner cavity of the crystallization cylinder 1;

[0056] The pushing assembly 404 of the pushing mechanism 4 pushes the crystals after filtering on the top surface of the receiving plate 5 to one end of the discharge port 102 under the action of the conveyor belt 403, and the crystals fall and are collected from the end of the receiving plate 5 located at one end of the discharge port 102;

[0057] When a large number of crystals adhere to the surface of the scraper strip 731, the hydraulic cylinder 72 controls the vertical frame 73 to move upward, so that the scraper strip 731 and the strip cleaning mechanism 74 slide relative to each other, and the strip cleaning frame 742 cleans the crystals attached to the surface of the scraper strip 731. After cleaning, the hydraulic cylinder 72 controls the vertical frame 73 to reset, so that the scraper strip 731 acts on the surface of the crystallization plate 3 again.
