Description

Technical Field

[0001] The utility model relates to the technical field of potassium nitrate crystal purification, in particular to a potassium nitrate crystal continuous conveying device for optical glass. Background Art

[0002] Optical glass is a special glass material, mainly used in the optical field. It has the ability to change the propagation direction of light and the relative spectral distribution of ultraviolet, visible or infrared light. Potassium nitrate plays an important role in its production, helping to remove bubbles and impurities in the glass, making the production purity of potassium nitrate more critical. Potassium nitrate with higher purity can also help improve the manufacturing performance of glass when it is put into optical glass production.

[0003] In the existing potassium nitrate crystallization and purification process, the crystallization operation is usually completed by cooling. However, the existing crystallization process is mostly carried out in a crystallization kettle, which makes the crystallization process take a long time, and the crystals need to wait until the crystallization process in the kettle is completed before they can be discharged, which easily causes the crystals to continue to accumulate and adhere to the inner wall of the kettle, resulting in a decrease in the crystallization process efficiency of the remaining solution in the kettle, making the overall preparation efficiency slow.

[0004] To this end, the inventors have designed and developed a continuous conveying device for potassium nitrate crystals for optical glass. After partial crystallization is completed, the crystals can be conveyed to a transmission device and continuously output in batches, thereby improving the production efficiency of potassium nitrate crystal purification processing.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The setting of the receiving plate ensures that the crystals falling from the crystallization plate can be effectively caught, avoiding the loss of crystals. The filtrate net filters the excess solution mixed in the crystals, allowing the solution to flow back to the bottom of the inner cavity of the crystallization tube, realizing the recycling of the solution and avoiding waste.

[0020] By setting up the crystallization plate, the crystallization plate is rotated inside the crystallization cylinder, so that the solution can continuously contact the surface of the crystallization plate, thereby improving the crystallization efficiency. The low temperature design of the crystallization plate surface is conducive to the rapid crystallization of the solution, further shortening the crystallization cycle.

[0021] Through the setting of the pushing mechanism, the pushing assembly can push the crystals on the top surface of the receiving plate to one end of the discharge port, realizing the automatic pushing and collection of the crystals and improving the production efficiency. In the process of pushing the crystals, the pushing plate can also synchronously scrape the top surface of the receiving plate and the inner surface of the side baffle, ensuring the cleanliness of the receiving plate and the side baffle and avoiding the residue and waste of crystals.

[0022] By setting up the scraper strip cleaning mechanism, the scraper strip can be automatically cleaned when a large number of crystals are adhered, ensuring the continuous and effective use of the scraper strip and avoiding the influence of excessive crystal adhesion on its normal function. The control of the hydraulic cylinder makes the scraper strip cleaning process more convenient and efficient.

[0023] By setting up a drive motor to drive the synchronous movement of the pushing mechanism and the supporting mechanism, the overall optimization and energy saving of the system are achieved. The pipe design connected to the bottom of the crystallization cylinder makes it more convenient to drain the solution inside the crystallization cylinder, which is beneficial to the continuous operation and subsequent maintenance of the system.

[0024] In summary, the utility model overcomes the shortcomings of the prior art. Through the combination of the crystallization stage and the conveying stage, the solution can utilize gravity after the crystallization treatment to directly convey, discharge and collect the crystals, thereby improving the efficiency of crystallization preparation and having high social use value and application prospects.

[0041] A receiving plate 5 is provided in the supporting mechanism 2, and a filtrate net 51 is provided on the top surface of the receiving plate 5 for filtering the crystals, and side baffles 52 are provided on both sides of the receiving plate 5. Through the setting of the receiving plate 5, the crystals attached to the surface of the crystallization plate 3 can be caught by the receiving plate 5 after falling from the top of the crystallization cylinder 1, and the excess solution mixed in the crystals will fall through the filtrate net 51 into the solution to be crystallized at the bottom of the inner cavity of the crystallization cylinder 1, avoiding waste of solution.

[0042] Specifically, the support mechanism 2 includes an active ring 201 rotatably mounted on the discharge port 102 , a connecting frame 202 for mounting the crystallization plate 3 is provided on the active ring 201 , and a driven ring 203 rotatably connected to the inner side of the crystallization cylinder 1 is provided at the other end of the connecting frame 202 .

[0043] Specifically, the crystallization cylinder 1 is provided with a pushing mechanism 4 located in the supporting mechanism 2, and the pushing mechanism 4 includes a driven roller 401 and a driving roller 402, the driven roller 401 is provided with a driven shaft 4011, and the driving roller 402 is provided with a driving shaft 4021;

[0044] The driven shaft 4011 and the driving shaft 4021 provide support for both ends of the receiving plate 5 respectively.

[0045] Specifically, a first bracket 4012 is provided inside the crystallization cylinder 1 for installing the driven shaft 4011, and a second bracket 4022 is provided outside the crystallization cylinder 1 for installing the driving shaft 4021. When the driving shaft 4021 drives the driving roller 402 to rotate, the driven shaft 4011 and the driven roller 401 can also rotate along with the rotation of the driving roller 402 through the setting of the conveyor belt 403, so that the pushing assembly 404 acts on the top surface of the receiving plate 5. The first bracket 4012 and the second bracket 4022 respectively provide fixing functions 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 supporting mechanism 2, and when the supporting mechanism 2 drives the crystallization plate 3 to rotate, it will not affect the pushing mechanism 4.

[0046] Specifically, a conveyor belt 403 is meshed with the driven roller 401 and the active roller 402, a pushing assembly 404 is provided on the conveyor belt 403, a driving motor 6 for driving the active shaft 4021 to rotate is provided on the second bracket 4022, and the rotation of the active roller 402 is provided by the rotation of the output shaft of the driving motor 6, so that the pushing assembly 404 can, under the action of the conveyor belt 403, push out and collect the crystals after filtering on the top surface of the receiving plate 5 from the discharge port 102.

[0047] Specifically, a side gear ring 21 is provided on the active ring 201, and a spur gear 61 meshing and matching with the side gear ring 21 is provided on the active shaft 4021. The side gear ring 21 is arranged to mesh and match with the active shaft 4021, so that when the driving motor 6 drives the internal components of the pushing mechanism 4 to rotate, the active shaft 4021 can synchronously drive the side gear ring 21 to rotate, so that the supporting mechanism 2 drives 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 pushing mechanism 4 can be carried out synchronously.

[0048] Specifically, the pushing assembly 404 includes a mounting frame 4041 connected to the conveyor belt 403, and the mounting frame 4041 is provided with a pushing plate 4042 acting on the top surface of the receiving plate 5. Through the setting of the pushing assembly 404, after the crystals fall on the top surface of the receiving plate 5 and the excess solution in the crystals is filtered through the filtrate net 51, the pushing plate 4042 can push the crystals on the top surface of the receiving plate 5 to one end of the discharge port 102. According to the continuous movement of the internal components of the pushing mechanism 4, the crystals can be dropped and collected from the end of the receiving plate 5 located at one end of the discharge port 102. When the pushing plate 4042 moves, the top surface of the receiving plate 5 and the inner surface of the side baffle 52 can be scraped synchronously, so that no crystals will be left attached to the top surface of the receiving plate 5 and the inner surface of the side baffle 52, thereby avoiding waste of crystals during transportation.

[0049] Specifically, an adjustment box 7 is provided on the top surface of the crystallization cylinder 1 , and a crossbeam frame 71 is provided in the adjustment port 103 . The arrangement of the adjustment port 103 and the adjustment box 7 facilitates the replacement operation of the crossbeam frame 71 .

[0050] 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. 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 setting of the scraper strip 731, when the crystallization plate 3 rotates from the bottom of the inner cavity of the crystallization tube 1 to the top of the inner cavity of the crystallization tube 1, the scraper strip 731 will block the crystals attached to the surface of the crystallization plate 3, allowing the crystals to detach from the surface of the crystallization plate 3. By utilizing the effect of gravity, the crystals can fall on the top surface of the receiving plate 5, and a small part of the solution contaminated by the crystallization plate 3 will also drip to the top surface of the receiving plate 5. 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 tube 1, thereby effectively avoiding the waste of solution.

[0051] Specifically, 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 fitted with the scraper bar 731. Through the arrangement of the hydraulic cylinder 72 and the strip clearing mechanism 74, when there are many crystals adhering to the surface of the scraper bar 731 due to cleaning, the hydraulic cylinder 72 can control the vertical frame 73 to move upward, so that the scraper bar 731 can slide relative to the strip clearing mechanism 74, so that the scraper bar 731 can move inside the strip clearing notch 743, so that the strip clearing frame 742 can clean the crystals attached to the surface of the scraper bar 731. After cleaning, the hydraulic cylinder 72 can control the vertical frame 73 to reset, so that the scraper bar 731 can act on the surface of the crystallization plate 3 again.

[0052] Working principle: In the present invention, the solution to be crystallized is firstly supplied to the inside of the crystallization cylinder 1 through the feed pipe 101, so that the solution can immerse the crystallization plate 3 at the height position at the bottom of the inner cavity of the crystallization cylinder 1;

[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.
