Description

Technical Field

[0001] This invention relates to the field of tricyclic azole pulverization technology, specifically to a nitrogen closed-loop system for pulverizing tricyclic azole. Background Technology

[0002] The nitrogen closed-loop system for tricyclazole pulverization is an inert gas protected closed-loop pulverization system.

[0003] Tricyclazole is an important fungicide technical material. In existing technology, it is usually ultra-finely pulverized using an air jet mill. However, this process has problems in actual production.

[0004] Firstly, tricyclazole dust is explosive, and the material is easily oxidized and deteriorated during the crushing process. When compressed air is used as the crushing medium, the high-speed airflow mixes with the dust to form an explosive gas, which poses a serious fire and explosion safety hazard. At the same time, it will cause the material to deteriorate and its quality to decline.

[0005] Secondly, after prolonged operation, the inner wall of the pulverizing nozzle is easily adhered and accumulated by tricyclazole fine powder, which gradually reduces the effective cross-sectional area of ​​the nozzle, decreases the jet airflow velocity, and significantly reduces the pulverizing efficiency. In severe cases, the nozzle becomes completely blocked, forcing the equipment to be shut down for cleaning.

[0006] Third, powder easily adheres to the blade gaps and surfaces of the classifying impeller, causing impeller dynamic imbalance, reduced classification accuracy, and continuous thickening of the adhesion layer, eventually blocking the airflow channel, requiring frequent shutdowns for manual disassembly and cleaning.

Detailed Implementation

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Please see Figures 1 to 13 This embodiment of a nitrogen closed-loop system for pulverizing tricycloazole includes a fixed frame 1, a feeder 11 fixedly installed inside the fixed frame 1, a screw feeder 12 provided in the feeder 11, an airflow pulverizer 2 provided on one side of the fixed frame 1, a transport pipe 21 fixedly installed on the outer side of the upper half of the airflow pulverizer 2, a cone 212 fixedly installed at the lower end of the airflow pulverizer 2, a base 22 fixedly installed at the lower end of the cone 212, a cyclone dust collector 3 provided on one side of the airflow pulverizer 2, a filter 4 provided on the side of the cyclone dust collector 3 away from the airflow pulverizer 2, an induced draft fan 5 provided on the side of the filter 4 away from the cyclone dust collector 3, an air compressor 6 provided on the side of the induced draft fan 5, and a tank 7 provided on the side of the air compressor 6 away from the induced draft fan 5.

[0047] The nitrogen closed-loop system of this application is used for the ultrafine grinding of tricyclazole materials. The entire system adopts a nitrogen closed-loop circulation process to solve the technical problems of the explosiveness of tricyclazole dust and the easy oxidation and deterioration of materials during the grinding process.

[0048] The fixed frame 1 serves as the feeding support structure of the system. The feeder 11 is fixedly installed inside it. The tricyclic azole raw material is temporarily stored by the feeder 11 and quantitatively fed by the screw feeder 12. The lower end of the feeder 11 is connected to the screw feeder 12, and the discharge end of the screw feeder 12 is connected to the air jet mill 2, thereby uniformly feeding the tricyclic azole material into the air jet mill 2.

[0049] The air jet mill 2 is set vertically. Its upper end receives material from the screw feeder 12 through the transport pipe 21. Its lower end is fixedly connected to the cone 212. The cone 212 has a cone-shaped structure that is narrow at the bottom and wide at the top. The base 22 is fixedly installed at the lower end of the cone 212. The base 22 is used to support and fix the air jet mill 2 as a whole.

[0050] The upper part of the air jet mill 2 is connected to the air inlet of the cyclone dust collector 3 through the transport pipe 21. The pulverized gas-solid mixture enters the cyclone dust collector 3 for gas-solid separation and collects the tricyclazole finished powder. The exhaust port of the cyclone dust collector 3 is connected to the air inlet of the filter 4 through the pipeline. The filter 4 further filters the trace dust remaining in the airflow to ensure the cleanliness of the circulating gas. The exhaust port of the filter 4 is connected to the air inlet of the induced draft fan 5 through the pipeline. The induced draft fan 5 provides airflow circulation power for the entire closed-loop system. The exhaust port of the induced draft fan 5 is connected to the air inlet of the air compressor 6 through the pipeline. The air compressor 6 pressurizes the circulating nitrogen. The pressurized nitrogen is transported to the tank 7 for temporary storage and pressure stabilization. The outlet of the tank 7 is then connected to the ring pipe 10 of the air jet mill 2 through the pipeline, thus forming a complete nitrogen closed-loop circulation loop.

[0051] Before the system is started, qualified nitrogen is first introduced into the tank 7 through the nitrogen replenishment valve. After the nitrogen is pressurized by the air compressor 6, it enters the pulverizing system to replace the nitrogen in the entire closed system. During the replacement process, the oxygen concentration in the system is monitored in real time by the oxygen content analyzer. Unqualified gas is discharged through the vent valve until the nitrogen purity in the system reaches the standard. After that, the vent valve is closed and the replacement is completed. Then, the equipment is started to run under no-load. After the system pressure, temperature and flow field are stabilized, the feeding and pulverizing begins.

[0052] The airflow pulverizer 2 is internally equipped with a separation mechanism 17 and a support mechanism 16. The support mechanism 16 includes a support fixing body 161, which has a lower cavity 1611 and an upper cavity 1612. A fixed support rod 1810 is fixedly installed on the inner wall of the upper cavity 1612. The fixed support rod 1810 is vertically arranged and provides sliding guidance for the drive plate 1811. The drive plate 1811 is slidably installed on the outer side of the fixed support rod 1810. When the drive plate 1811 slides back and forth along the fixed support rod 1810 under the drive of the slide rod 1814, the inclined surface of the upper surface of the drive plate 1811 relative to the lower surface of the extrusion block 189 generates a relative... The displacement drives the extrusion block 189 to reciprocate, which in turn drives the loosening plate 182 to reciprocate, continuously loosening the material above the loosening plate 182 to prevent material blockage. The drive plate 1811 can slide along the axial direction of the fixed support rod 1810. A slide rod 1814 is fixedly installed on the lower side of the drive plate 1811. The slide rod 1814 is slidably connected to the undulating strip block 188. An inclined surface is opened on one side of the upper surface of the drive plate 1811. This inclined surface is used to cooperate with the extrusion block 189 for transmission. A sealing plate 183 is slidably provided on the inner wall of the lower cavity 1611. When blockage occurs, the internal pressure of the connecting pipe 103 increases. At this time, the pressure will push the sealing plate 183 to slide.

[0053] The sealing plate 183 is located below the loosening plate 182. A movable cylinder 184, a telescopic rod 187, and a spring 186 are fixedly installed at the lower end of the sealing plate 183. The spring 186 applies an upward elastic restoring force to the sealing plate 183. A spiral groove 185 is formed on the outer side of the movable cylinder 184, and a drive wheel 181 is provided on the outer side of the movable cylinder 184. The outer side of the drive wheel 181 is slidably connected to the inside of the support fixing body 161. A small slider 18111 is fixedly installed on the inner side of the drive wheel 181, and the small slider 18111 is slidably connected to the inner wall of the spiral groove 185. When the sealing plate 183 slides up and down, it drives the movable cylinder 184 to move up and down axially, and the small slider 18111 moves along the spiral groove 185. The groove 185 slides relative to each other, the drive wheel 181 rotates, and the upper surface of the drive wheel 181 is fixedly installed with undulating strips 188. When the drive wheel 181 drives the undulating strips 188 to rotate, the lower end of the slide rod 1814 slides along the upper surface of the undulating strips 188, thereby causing the slide rod 1814 to generate axial reciprocating motion, which in turn drives the drive plate 1811 to slide reciprocally along the fixed support rod 1810. The moving cylinder 184 is sleeved on the outside of the spring 186 and the telescopic rod 187. The spring 186 is sleeved on the outside of the telescopic rod 187. The support fixing body 161 has a through connection port 1613, and the inner wall of the support fixing body 161 has a sliding groove 1614.

[0054] The sliding groove 1614 has limit grooves 1615 on both sides of its inner wall. The limit grooves 1615 provide sliding guidance and limit for the rotating wheel 1812. An annular pipe 10 is fixedly connected to the outside of the air jet mill 2. Two symmetrically distributed air inlet pipes 101 are fixedly installed around the annular pipe 10. Several short conveying pipes 102 are fixedly installed on the outside of the annular pipe 10. A connecting pipe 103 is fixedly connected to the end of the short conveying pipe 102 away from the annular pipe 10. One end of the connecting pipe 103 extends to the air jet mill 2. The nozzle 104 is fixedly connected inside the support mechanism 16. The anti-blocking mechanism 18 is provided inside the support mechanism 16. The anti-blocking mechanism 18 includes a loosening plate 182. A pressing block 189 is fixedly connected to the lower surface of the loosening plate 182. The pressing block 189 is located above the drive plate 1811. The lower surface of the pressing block 189 cooperates with the inclined surface of the upper surface of the drive plate 1811. A telescopic rod 1888 and a spring 1813 are fixedly connected to one side of the pressing block 189. The spring 1813 is sleeved on the outside of the telescopic rod 1888.

[0055] The ends of the telescopic rod 1888 and spring 1813 away from the extrusion block 189 are fixedly connected to the rotating wheel 1812. The leakage hole 1821 ensures that the sealing plate 183 can detect pressure at all times. The circumference of the rotating wheel 1812 is slidably connected to the inner wall of the limiting slide groove 1615. The loosening plate 182 has a through hole 1821 on one side. The separation mechanism 17 includes a limiting body 171, a drive shaft 1710, and a drive ring 178. When the drive shaft 1710 rotates, it drives the impeller 175 to rotate synchronously. The end of the drive shaft 1710 away from the impeller 175 is fixedly connected to the drive motor 172. The inner wall of the drive shaft 1710 has a circulation groove 1714, which is a reciprocating guide groove. The limiting body 171 has a separation chamber 1711 inside. The end of the drive shaft 1710 near the fixed body 173 is fixedly connected to the end of the impeller 175.

[0056] One end of the drive ring 178 is fixedly connected to the connecting body 179. The connecting body 179 and the push body 1712 are located inside the limiting body 171. A single shaft 1799 is slidably connected inside the drive ring 178 and the connecting body 179, providing guidance for the reciprocating motion of the drive ring 178, the push body 1712, and the connecting body 179. The push body 1712 is slidably connected to the outside of the single shaft 1799 inside the drive shaft 1710. A part of the single shaft 1799 is located inside the drive shaft 1710. Therefore, the outside of this part of the single shaft 1799 is slidably connected to the push body 1712. A slider 1713 is fixedly installed on the outside of the push body 1712. One end of the slider 1713 is slidably connected to the inner wall of the circulation groove 1714. One end of the single shaft 1799 is rotatably connected to the inner wall of the drive shaft 1710. The single shaft 1799 does not rotate with the drive shaft 1710.

[0057] A fixed body 173 is fixedly connected to the end of the single shaft 1799 away from the drive shaft 1710. The outer side of the fixed body 173 is rotatably connected to the inside of the impeller 175. A fixed shaft 174 is rotatably mounted on one side of the fixed body 173. The fixed shaft 174 rotates inside the limiting body 171. The impeller 175 is rotatably connected to the end of the fixed shaft 174 away from the fixed body 173. The high-speed rotation of the impeller 175 generates a centrifugal force field, causing coarse particles to be thrown towards the inner wall of the separation chamber 1711 and fall back into the crushing chamber under the action of centrifugal force. Fine particles are carried by the airflow through the gap of the impeller 175 and enter the subsequent collection system. The impeller 175 is located inside the separation chamber 1711. The fixed shaft 174 is sleeved on the outside of the single shaft 1799. Several connecting rods 177 are fixedly connected to the outside of the drive ring 178. The ends of the connecting rods 177 away from the drive ring 178 are all fixedly connected to a scraper ring 176. The scraper ring 176 is sleeved on the outside of the impeller 175. When the drive shaft... When 1710 rotates, the circulation groove 1714 rotates synchronously with the drive shaft 1710. Under the guidance of the circulation groove 1714, the slider 1713 drives the pusher 1712 to reciprocate along the axial direction of the single shaft 1799. The pusher 1712 pushes the connecting body 179 and the drive ring 178 to reciprocate along the axial direction of the single shaft 1799. The drive ring 178 drives the scraper ring 176 to reciprocate along the axial direction of the impeller 175 through the connecting rod 177. During the reciprocating motion, the scraper ring 176 scrapes and cleans the powder adhering to the gap between the blades and the surface of the impeller 175 to prevent the powder from adhering and clogging the impeller 175, thus ensuring the stability of the classification efficiency. Magnets are installed at the corresponding ends of the pusher 1712 and the connecting body 179. The magnetic poles of the two magnets are opposite, so the pusher 1712 can drive the connecting body 179. At the same time, when the scraper ring 176 reaches one side of the impeller 175, the pusher 1712 separates from the connecting body 179, and then the two separate.

[0058] The working process of the nitrogen closed-loop system for tricyclazole pulverization in this application is as follows:

[0059] Before startup, qualified nitrogen enters tank 7 through nitrogen replenishment valve, then enters air compressor 6 through pipeline. The nitrogen mixes with any residual air and is compressed by air compressor 6. The compressed gas is then delivered to subsequent pipelines. Once the system pressure reaches the preset value, the valve next to air compressor 6 closes, entering pure nitrogen purging mode. The pressurized nitrogen enters the airflow pulverizer 2 through loop pipe 10, inlet pipe 101, delivery short pipe 102, connecting pipe 103, and nozzle 104, purging the entire closed-loop system with nitrogen. Gas with unqualified oxygen content in the system is discharged through cyclone dust collector 3, filter 4, and induced draft fan 5, then discharged by vent valve until the oxygen content analyzer detects that the nitrogen purity in the system meets the standard. The vent valve then closes, and the purging process is complete.

[0060] After the nitrogen purging is qualified, start the drive motor 172, induced draft fan 5, air compressor 6 and other equipment, run them under no-load for about 5 minutes to stabilize the pressure, temperature and flow field in the system and ensure that the equipment meets the pulverizing conditions.

[0061] Tricyclic azole material is quantitatively conveyed by feeder 11 through screw feeder 12 and enters the crushing chamber of air jet mill 2. Pressurized nitrogen gas is injected at high speed through multiple nozzles 104 from ring pipe 10, forming a high-speed swirling field in the crushing chamber. Under the drive of the high-speed airflow, the tricyclic azole material is ultra-finely crushed through high-speed self-collision and shearing between particles.

[0062] The oxygen content analyzer, vent valve, and through valve are existing technologies and will not be described in detail here, nor are they shown in the figure.

[0063] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
