Description

Technical Field

[0001] This invention belongs to the field of grinding equipment technology, specifically relating to a fine grinding device and its operation method for cyanuric acid production. Background Technology

[0002] Cyanuric acid, also known as cyanuric acid, is a white crystalline solid that precipitates from water, containing two molecules of water of crystallization. It has a slightly bitter taste, is essentially non-toxic, soluble in hot water, slightly soluble in cold water, and its aqueous solution is acidic. It is soluble in aqueous solutions of potassium hydroxide and sodium hydroxide, but insoluble in cold alcohols, ethers, benzene, and other organic solvents. Cyanuric acid is mainly used to manufacture chlorinated derivatives and in the synthesis of cyanuric acid-formaldehyde resins, epoxy resins, and herbicides.

[0003] In the production process of cyanuric acid, it is necessary to grind the cyanuric acid to make it suitable for mixing in subsequent processes;

[0004] However, a common problem with current grinding devices is that fine powder from grinding adheres to the grinding head after grinding. If not cleaned, this will affect subsequent material grinding. The current cleaning method is to remove the grinding head and scrape it off with a scraper. However, the cyanuric acid scraped off in this way is in the form of large particles or even plates, which is not conducive to subsequent use. Summary of the Invention

[0005] In view of the problems raised in the background art above, the purpose of the present invention is to provide a fine grinding device and operating method for the production of cyanuric acid.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0007] A fine grinding device for producing cyanuric acid includes a tank body, a mounting groove on the top of the tank body, a motor slidably mounted in the mounting groove, an extension frame mounted on the upper side of the tank body above the mounting groove, a telescopic cylinder mounted on the top of the extension frame, an output end of the telescopic cylinder connected to a mounting plate located in the mounting groove, and a motor mounted on the mounting plate.

[0008] The tank body is equipped with a grinding cylinder located below the mounting groove. The grinding cylinder has an upper grinding table at the top. The motor output is connected to a grinding head located inside the grinding cylinder. The upper part of the grinding head matches the size of the upper grinding table. A feeding trough is installed on the outer side of the top of the tank body. A feeding pipe is installed between the feeding trough and the upper grinding table. A first electric valve body is installed on the feeding pipe.

[0009] The grinding cylinder is equipped with a cleaning mechanism, which includes a high-pressure blower installed on the outer wall of the tank. The output end of the high-pressure blower is connected to an air pipe, and the output end of the air pipe is connected to an annular cavity installed on the outside of the grinding cylinder. The grinding cylinder is annularly and uniformly provided with a plurality of through holes communicating with the annular cavity.

[0010] A lower grinding shell is installed on the lower side of the grinding cylinder. The interior of the lower grinding shell matches the dimensions of the lower half of the grinding head. A feeding pipe is connected to the output end of the lower grinding shell. A second electric valve body is installed on the feeding pipe. A vibration motor with its output end in contact with the lower grinding shell is installed on the tank.

[0011] A method for operating a fine grinding device for cyanuric acid production includes the following steps:

[0012] S1. Equipment debugging;

[0013] Adjust the limit position of the telescopic cylinder's upward movement, thereby adjusting the gap between the upper half of the grinding head and the upper grinding table; adjust the limit position of the telescopic cylinder's downward movement, thereby adjusting the gap between the lower half of the grinding head and the lower grinding shell.

[0014] S2, Set parameters;

[0015] S3, Loading materials;

[0016] Close the first electric valve and the second electric valve, and add cyanuric acid into the feeding tank;

[0017] S4. Start the equipment and wait for the material to be fed.

[0018] Furthermore, both the mounting slot and the extension frame are equipped with sliding grooves, and the mounting plate is slidably installed in the sliding grooves. This design further enhances the stability of the mounting plate's lifting and lowering, and reduces the stress on the motor spindle during movement.

[0019] Furthermore, bearings are installed at the positions where the mounting groove and the grinding cylinder contact the output end of the motor, and rotating sealing rings are installed at both ends of the bearings. This design ensures both rotational performance and sealing performance.

[0020] Furthermore, the feed trough has an inclined platform inside, a design that ensures the flowability of cyanuric acid under its own weight.

[0021] Furthermore, the inner walls of the grinding cylinder, the feeding trough, the feeding pipe, and the unloading pipe are all coated. This design not only prevents rust but also ensures smoothness and prevents sticking.

[0022] Furthermore, the through hole is equipped with a one-way nozzle, a design that serves to pressurize and prevent entry.

[0023] Furthermore, the output end of the feed pipe is equipped with a screen cover, a design that allows for further sieving of cyanuric acid powder.

[0024] Furthermore, in step S2, the parameters include the time the telescopic cylinder is in the retracted state, the time the telescopic cylinder is in the extended state, the rotational speed of the motor, the opening and closing interval of the first electric valve body, the opening and closing interval of the second electric valve body, the air pressure of the high-pressure blower, the running time of the high-pressure blower, the operating power of the vibration motor, and the running time of the vibration motor. This design ensures the accuracy of automatic operation.

[0025] Furthermore, in step S4, the output end of the feed pipe is connected to a closed bag or cavity. This design allows the cyanuric acid powder to be collected even when affected by wind, and it is less likely to fly out of the bag or cavity used for collection.

[0026] The beneficial effects of using the present invention are as follows:

[0027] The structural design of this invention allows for two different degrees of grinding of cyanuric acid within a limited space, achieving the purpose of fine grinding and ensuring that the produced cyanuric acid meets the requirements for use.

[0028] The structural design of this invention enables air knife cleaning of the grinding head under the action of a high-pressure blower. While removing the blocky adhesive on the grinding head, it can also crush the adhesive, ensuring that the quality of the produced cyanuric acid meets the requirements for subsequent use.

[0029] This invention features a compact structure, enables fully automated fine grinding, is easy to operate, saves manpower, and ensures production efficiency. Attached Figure Description

[0039] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0040] like Figures 1-5 As shown, a fine grinding device for producing cyanuric acid according to the present invention includes a tank body 1, a mounting groove 2 on the top of the tank body 1, a motor 3 slidably mounted in the mounting groove 2, an extension frame 4 mounted on the upper side of the tank body 1 above the mounting groove 2, a telescopic cylinder 5 mounted on the top of the extension frame 4, an output end of the telescopic cylinder 5 connected to a mounting plate 6 located in the mounting groove 2, and the motor 3 mounted on the mounting plate 6.

[0041] Inside the tank body 1, a grinding cylinder 7 is installed on the lower side of the mounting groove 2. The top of the grinding cylinder 7 is provided with an upper grinding table 8. The output end of the motor 3 is connected to a grinding head 9 located inside the grinding cylinder 7. The upper half of the grinding head 9 matches the specifications and dimensions of the upper grinding table 8. A feeding trough 10 is installed on the outer side of the top of the tank body 1. A feeding pipe 11 is installed between the feeding trough 10 and the upper grinding table 8. A first electric valve body 12 is installed on the feeding pipe 11.

[0042] The grinding cylinder 7 is equipped with a cleaning mechanism 13, which includes a high-pressure blower 131 installed on the outer wall of the tank body 1. The output end of the high-pressure blower 131 is connected to an air pipe 132, and the output end of the air pipe 132 is connected to an annular cavity 133 installed on the outside of the grinding cylinder 7. The grinding cylinder 7 is annularly and uniformly provided with a number of through holes 134 that communicate with the annular cavity 133.

[0043] A lower grinding shell 14 is installed on the lower side of the grinding cylinder 7. The internal dimensions of the lower grinding shell 14 match those of the lower half of the grinding head 9. The output end of the lower grinding shell 14 is connected to a feeding pipe 15. A second electric valve body 16 is installed on the feeding pipe 15. A vibration motor 17 with its output end in contact with the lower grinding shell 14 is installed on the tank body 1.

[0044] A method for operating a fine grinding device for cyanuric acid production includes the following steps:

[0045] S1. Equipment debugging;

[0046] Adjust the limit position of the telescopic cylinder 5 to move upward, and then adjust the gap between the upper part of the grinding head 9 and the upper grinding table 8. Adjust the limit position of the telescopic cylinder 5 to move downward, and then adjust the gap between the lower part of the grinding head 9 and the lower grinding shell 14.

[0047] S2, Set parameters;

[0048] S3, Loading materials;

[0049] Close the first electric valve body 12 and the second electric valve body 16, and add cyanuric acid into the feeding tank 10;

[0050] S4. Start the equipment and wait for the material to be fed.

[0051] In this implementation case, when using a fine grinding device and operating method for cyanuric acid production, the particle size of the cyanuric acid powder to be finely ground is first determined. This particle size is the gap size between the lower half of the grinding head 9 and the lower grinding shell 14. The gap size between the upper half of the grinding head 9 and the upper grinding table 8 is about twice as large as the gap size between the lower half of the grinding head 9 and the lower grinding shell 14. This gap size adjustment causes less damage to the grinding head 9 and results in better grinding effect and less clumping. The adjustment method is to limit the maximum retraction stroke and the maximum extension stroke of the telescopic cylinder 5. This point is easy for those skilled in the art to understand.

[0052] Then the parameters of each power component are adjusted;

[0053] After adjustment, the telescopic cylinder 5 is in the position of maximum retraction stroke, that is, the grinding head 9 is located at the upper grinding table 8 and cooperates with the upper grinding table 8. The first electric valve body 12 and the second electric valve body 16 are closed, and the material is fed into the feeding trough 10. After the material is fed, the motor 3 runs first to drive the grinding head 9 to rotate. The first electric valve body 12 opens, and the cyanuric acid in the feeding trough 10 enters the gap between the grinding head 9 and the upper grinding table 8 through the feeding pipe 11. The rotating grinding head 9 performs the first grinding and falls into the lower grinding shell 14. After the material is fed into the feeding trough 10 for a period of time or after the material is fed, the first electric valve body 12 stops, and the motor 3 continues to run for no less than one minute before stopping. The continued operation of the motor 3 is to ensure that the cyanuric acid in the feeding pipe 11 is ground completely for the first time.

[0054] When the telescopic cylinder 5 operates, it drives the motor 3 to descend. During the descent, the motor 3 drives the grinding head 9 to rotate. The gap between the lower half of the grinding head 9 and the lower grinding shell 14 will be used to grind the cyanuric acid for the second time. It should be noted that the roughness of the upper half and the lower half of the grinding head 9 can be different to ensure the grinding accuracy. This change is easy for those skilled in the art to understand.

[0055] After the second grinding is completed, the second electric valve body 16 is opened, and the cyanuric acid powder is discharged from the feed pipe 15. After the second grinding has been carried out for a period of time, the telescopic cylinder 5 drives the motor 3 to slowly shake up and down. At the same time, the high-pressure blower 131 and the vibration motor 17 are running. Under the effect of the high-pressure blower 131, the air discharged from the annular cavity 133 through the through hole 134 is in a line shape, which cleans the grinding head 9 with air knife. While cleaning, the grinding head 9 keeps rotating to ensure thorough cleaning. Under the air cutting, the objects adhering to the grinding head 9 are cut into powder. Under the effect of the vibration motor 17, the material adhering to the lower grinding shell 14 is also crushed to ensure the quality of the feed.

[0056] Preferably, both the mounting slot 2 and the extension frame 4 are equipped with sliding grooves 18, and the mounting plate 6 is slidably installed in the sliding grooves 18. This design further enhances the lifting stability of the mounting plate 6 and reduces the stress on the main shaft of the motor 3 during movement. In fact, a structure that ensures lifting stability can also be considered depending on the specific circumstances.

[0057] The preferred mounting slot 2 and the position where the grinding cylinder 7 contacts the output end of the motor 3 are fitted with bearings, and the bearings are fitted with rotating sealing rings at both ends. This design ensures both rotation and sealing. In fact, a structure that ensures both rotation and sealing can also be considered depending on the specific circumstances.

[0058] The preferred design is an inclined platform inside the feeding tank 10. This design ensures the fluidity of cyanuric acid under its own weight. In fact, the inclination of the inclined platform can also be considered according to the specific situation.

[0059] The inner walls of the preferred grinding cylinder 7, feeding trough 10, feeding pipe 11 and discharging pipe 15 are all coated. This design not only prevents rust but also ensures smoothness and prevents sticking. In fact, measures to prevent sticking can also be considered depending on the specific situation.

[0060] The preferred through-hole 134 is equipped with a one-way nozzle 135. This design serves the purpose of pressurization and preventing ingress. In fact, the specifications and models of the one-way nozzle 135 can also be selected according to specific circumstances.

[0061] Preferably, a screen cover 19 is installed at the output end of the feed pipe 15. This design can further screen out cyanuric acid powder. In fact, the specifications and dimensions of the screen cover 19 can also be considered according to specific circumstances.

[0062] In the preferred step S2, the parameters include the time when the telescopic cylinder 5 is in the retracted state, the time when the telescopic cylinder 5 is in the extended state, the speed of the motor 3, the opening and closing interval of the first electric valve body 12, the opening and closing interval of the second electric valve body 16, the air pressure of the high-pressure blower 131, the running time of the high-pressure blower 131, the operating power of the vibration motor 17, and the running time of the vibration motor 17. This design ensures the accuracy of automatic operation. In fact, the parameter settings can also be considered according to specific circumstances.

[0063] In preferred step S4, the output end of the feed pipe 15 is connected to a closed bag or cavity. This design allows for the collection of cyanuric acid powder even when affected by wind, and it is less likely to fly out of the bag or cavity used for collection. In fact, the choice of feed material can also be considered according to specific circumstances.

[0064] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
