Description

Technical Field

[0001] The invention relates to the technical field of spray guns, in particular to a yellow phosphorus efficient and safe phosphorus supply spray gun. Background Art

[0002] A spray gun is a spraying device used to release liquids, particles or gases into a jet onto a target surface, using compressed air or other power sources to eject the material. A phosphorus spray gun is a special type of spray gun used to spray materials containing the element phosphorus. Yellow phosphorus can be used to prepare industrial products such as chemicals, pesticides, and insecticides. Phosphorus spray guns can be used in these industrial processes for spraying and coating liquid yellow phosphorus.

[0003] In the prior art, during the use of the yellow phosphorus efficient and safe phosphorus supply spray gun, it is necessary to transport the liquid yellow phosphorus inside the pipeline to the nozzle by delivering compressed gas, and then spray the yellow phosphorus out through the nozzle. When the external gas supply system is closed and the gas supply is stopped, part of the liquid yellow phosphorus will remain at the connection between the nozzle and the pipeline. When the nozzle is damaged or blocked after long-term use and needs to be replaced and repaired, the staff is required to manually unscrew the nozzle from the pipeline connection. Since liquid yellow phosphorus remains at the connection between the nozzle and the pipeline, yellow phosphorus leakage is likely to occur during the process of unscrewing and disassembling the nozzle, which will pose a potential threat to the health and safety of the operator. When yellow phosphorus accidentally drips onto the ground, it will not only cause a dirty environment, but also have a negative impact on the production system.

[0038] In this embodiment, when in use, the solenoid valve 103, the negative pressure pump 201, the alarm 204, the flow meter 305, the forward and reverse motor 402, the laser ranging sensor 408, the micro hydraulic rod 504 and the PLC controller 203 are electrically connected, the phosphorus delivery pipe 101 is connected to the external yellow phosphorus delivery system, and the liquid yellow phosphorus is delivered to the phosphorus delivery pipe 101 through the external yellow phosphorus delivery system. One end of the gas injection pipe 102 is connected to the external gas source supply system, and the compressed gas is introduced into the phosphorus delivery pipe 101 through the external gas source supply system to provide power and pressure for phosphorus spraying, so that the liquid yellow phosphorus flows through the solenoid valve 103 into the threaded pipe 104, and finally enters the interior of the nozzle body 105, and the liquid yellow phosphorus is sprayed out through the nozzle body 105. When the nozzle body 1 05 When a problem occurs and needs to be repaired or replaced, the external yellow phosphorus delivery system and the gas supply system are turned off to stop the phosphorus spraying assembly 1 from working. Then, the solenoid valve 103 is started through the PLC controller 203 to close the solenoid valve 103, separating the threaded pipe 104 from the phosphorus delivery pipe 101. Then, the forward and reverse motors 402 and the laser ranging sensor 408 are started. The output end of the forward and reverse motors 402 rotates the gear 404, and at the same time, the row of teeth 406 meshing with the gear 406 moves toward the fixed block 411, and then the first connecting block 418 slides out of the first sliding hole 208, and the first sealing block 419 and the first sealing sleeve 420 move out of the first sealing groove 211, and then move outward through the first sliding hole 208. , while the row of teeth 406 moves, it will gradually squeeze the two telescopic rods 410, so that the two telescopic rods 410 are contracted together at the same time. When the telescopic rods 410 are fully contracted, the thrust of the row of teeth 406 will push the telescopic rods 410 to move together, and then push the fixed block 411 and the second connecting block 413 to move, so that the second sealing block 414 drives the second sealing sleeve 415 to move into the second sealing groove 422. At the same time, the laser ranging sensor 408 will emit a laser beam to the detection block 409, and calculate the distance between the laser ranging sensor 408 and the detection block 409 according to the time of receiving the reflected laser beam, and transmit the detected distance data to the PLC controller 203 in the form of an electrical signal.

When the distance data exceeds the set maximum working threshold, the PLC controller 203 will control the forward and reverse motors 402 to turn off. At this time, the second sealing sleeve 415 is completely embedded in the second sealing groove 422, and the outer surface of the second sealing sleeve 415 fits tightly with the inner wall of the second sealing groove 422 to seal the second sealing ring 412, thereby sealing the connecting pipe 304, without affecting the subsequent suction pipe 202 to suck the liquid yellow phosphorus at the connection between the nozzle body 105 and the threaded pipe 104. The first sealing sleeve 420 is removed from the first sealing groove 211, and the first sealing ring 209 is in an open state. Fig.11 As shown, the protection component 5 is then started to protect the first sealing groove 211, and then the negative pressure pump 201 is started to suck out the liquid yellow phosphorus inside the nozzle body 105 and the threaded tube 104 through the suction pipe 202, enter the suction pipe 202, and then flow downward through the space between the first sealing sleeve 420 and the sealing gasket 503, and then continue to flow along the suction pipe 202 to the discharge pipe 205, and finally flow to the inside of the collecting cylinder 206 to collect the yellow phosphorus. Through the cooperation of the suction component 2, the sealing component 4 and the protection component 5, the effect of sucking the yellow phosphorus at the connection is achieved, so as to avoid leakage of the liquid yellow phosphorus inside the nozzle body 105 and the threaded tube 104 during subsequent disassembly, thereby improving the safety of the operator and preventing the liquid yellow phosphorus from leaking out. Phosphorus drips onto the ground, causing an impact on the environment. The problem of liquid yellow phosphorus remaining at the connection between the nozzle and the pipeline during the use of the yellow phosphorus efficient and safe phosphorus supply spray gun is solved. During the removal of the nozzle, yellow phosphorus leakage is likely to occur, posing a potential threat to the health and safety of the operator. When yellow phosphorus accidentally drips onto the ground, it will not only cause a dirty environment, but also have a negative impact on the production system. Among them, the first sealing sleeve 420, the sealing gasket 503 and the arc sealing ring 502 are all made of polyimide material, which has excellent chemical corrosion resistance and outstanding high-temperature stability. It can maintain the stability of its physical and chemical properties at high temperatures, and has good elastic recovery performance and wear resistance, and can provide reliable sealing performance.

The inside of the detection plate 301 is fixedly installed on the outer surface of the threaded tube 104, and a plurality of suction pipes 307 are fixedly connected to the outer surface of the annular tube 303, and one end of the plurality of suction pipes 307 are fixedly passed through the detection plate 301 to the inside of the suction groove 308.

[0040] In this embodiment, when in use, after the yellow phosphorus in the nozzle body 105 and the threaded tube 104 is sucked and collected by the sealing component 4, the protective component 5 and the suction component 2, the nozzle body 105 can be unscrewed from the threaded tube 104 and replaced with a new nozzle body 105. When the nozzle body 105 and the threaded tube 104 are tightly connected, the nozzle body 105 will fit tightly with the outer surface of the rubber ring 302, and a sealed state is formed between the nozzle body 105 and the detection plate 301. When the nozzle body 105 and the threaded tube 104 are not tightly connected, the contact between the nozzle body 105 and the outer surface of the rubber ring 302 is not tight, and a gap will appear. The protective component 5 and the sealing component 4 are started again to reset the protective component 5. At this time, the output end of the forward and reverse motor 402 rotates in the opposite direction, driving the gear 404 to rotate in the opposite direction, and then driving the row of teeth 406 to move toward the suction tube 202, so that the first sealing sleeve 420 is reset and moves to the inside of the first sealing groove 211. Fig. 9As shown, the first sealing ring 209 and one end of the suction pipe 202 are sealed, and the row of teeth 406 will pull the telescopic rod 410 apart. When the telescopic rod 410 is fully unfolded, it will continue to pull the fixed block 411 and the second connecting block 413 to move, and further pull the second sealing sleeve 415 out of the second sealing groove 422. At this time, the second sealing ring 412 and the inside of the connecting pipe 304 become a flow state, and the negative pressure pump 201 is started to suck air into the suction groove 308 through multiple suction pipes 307. The sucked gas enters the connecting pipe 304 through the annular pipe 303, and then enters the fixed pipe 306 through the flow meter 305. The gas flow is detected by the flow meter 305, and the detection result is transmitted to the PLC controller 203 for identification and comparison. When the gas flow does not match the set range value, it means that the connection between the nozzle body 105 and the threaded tube 104 is not tight. During subsequent use, there is a risk of yellow phosphorus leakage. The PLC controller 203 will control the alarm 204 to sound, reminding the staff that the nozzle body 105 needs to be reinstalled. With the cooperation of the detection component 3 and the sealing component 4, the effect of sealing detection is achieved, the tightness of the connection between the nozzle body 105 and the threaded tube 104 is checked, and an alarm is issued at the first time.

[0041] Embodiment 3: Figure 9-12 As shown, the protection component 5 includes an arc plate 501, an arc sealing ring 502 is fixedly sleeved on the outer surface of the arc plate 501, a sealing gasket 503 is fixedly connected to the inner wall of the arc sealing ring 502, an embedded groove 213 is provided on the bottom surface of the inside of the first sealing groove 211, an annular groove 212 is provided inside the first sealing ring 209, two micro hydraulic rods 504 are fixedly installed on the bottom surface of the inside of the annular groove 212, the output ends of the two micro hydraulic rods 504 are fixedly installed on the bottom of the arc plate 501, the output ends of the two micro hydraulic rods 504 are fixedly penetrated into the inside of the arc sealing ring 502, and the two micro hydraulic rods 5 The output ends of 04 are all movable through the annular groove 212 to the inside of the embedded groove 213, the outer surface of the arc-shaped sealing ring 502 is movably embedded in the inside of the embedded groove 213, and a plurality of movable rods 505 are fixedly installed at the bottom of the arc-shaped plate 501. The bottom ends of the plurality of movable rods 505 are all fixedly installed through the bottom of the arc-shaped sealing ring 502, and the bottom ends of the plurality of movable rods 505 are all movable through the inside of the annular groove 212. A cleaning groove 214 is provided on the top surface of the inside of the first sealing groove 211, and an arc-shaped scraper strip 210 is fixedly installed on the top surface of the inside of the cleaning groove 214, and the bottom of the arc-shaped scraper strip 210 is in contact with the top of the first sealing sleeve 420.

[0042] In this embodiment, when in use, the first sealing ring 209 is opened and the second sealing ring 412 is closed through the sealing assembly 4, and then the two micro hydraulic rods 504 are started at the same time to push the arc plate 501 to move upward from the embedded groove 213 to the first sealing groove 211, and drive the sealing gasket 503 to move upward together. When the output end of the micro hydraulic rod 504 is fully extended, the micro hydraulic rod 504 will automatically close, so that the top of the arc sealing ring 502 is in contact with the top surface of the first sealing groove 211. The structure of the sealing gasket 503 is as shown in FIG. Fig.12 As shown, a groove is opened near both sides of the top, so that the outer surface of the first sealing sleeve 420 falls into the two grooves of the sealing gasket 503. At this time, the sealing gasket 503 fits with the outer surface of the first sealing sleeve 420, and the top of the arc-shaped sealing ring 502 fits with the top surface inside the first sealing groove 211. Fig.11 As shown, the first sealing groove 211 is protected so that liquid yellow phosphorus flows through the space between the first sealing sleeve 420 and the sealing gasket 503, preventing part of the yellow phosphorus from flowing into the first sealing groove 211, thereby flowing to the outer surface of the suction pipe 202 through the space between the first sealing groove 211 and the first sealing sleeve 420, thereby achieving a protective effect to prevent liquid leakage. When the first sealing sleeve 420 moves outward, it will pass through the arc-shaped scraper strip 210, and the arc-shaped scraper strip 210 will scrape the yellow phosphorus on the top of the first sealing sleeve 420 to the inside of the first sealing ring 209, preventing a small amount of yellow phosphorus on the top of the first sealing sleeve 420 from dripping onto the outer surface of the suction pipe 202.

[0043] The effect and working principle achieved by the entire mechanism are as follows: liquid yellow phosphorus is transported to the phosphorus delivery pipe 101 through an external yellow phosphorus delivery system, compressed gas is introduced into the phosphorus delivery pipe 101 through an external gas source supply system, power and pressure are provided for phosphorus spraying, so that the liquid yellow phosphorus flows through the solenoid valve 103 into the threaded pipe 104, and the liquid yellow phosphorus is sprayed out through the nozzle body 105. When the nozzle body 105 has a problem and needs to be repaired or replaced, the external yellow phosphorus delivery system and the gas source supply system are closed, so that the phosphorus spraying component 1 stops working, and then the solenoid valve 103 is started through the PLC controller 203, so that the solenoid valve 103 is in a closed state, the threaded pipe 104 is separated from the phosphorus delivery pipe 101, and then the forward and reverse motor 402 and the laser ranging sensor 408 are started, and the gear 404 is driven to rotate by the forward and reverse motor 402, and the row of teeth 406 is driven to move toward the fixed block 411, and then the first connecting block 418 is driven to slide out, and the first sealing sleeve 420 is driven from the first sealing block 419. The first and second connecting blocks 413 are moved out of the second sealing groove 422, and then move outward through the first sliding hole 208. The row of teeth 406 gradually squeezes the two telescopic rods 410 while moving, so that they are contracted together. When the telescopic rod 410 is fully contracted, the thrust of the row of teeth 406 pushes the telescopic rod 410, the fixing block 411 and the second connecting block 413 to move, so that the second sealing block 414 drives the second sealing sleeve 415 to move into the second sealing groove 422. At the same time, the laser ranging sensor 408 calculates the distance between the laser ranging sensor 408 and the detection block 409, and transmits the detected distance data to the PLC controller 203 for identification and comparison. When the distance data exceeds the set maximum working threshold, the PLC controller 203 controls the forward and reverse motors 402 to turn off. At this time, the second sealing sleeve 415 is completely embedded in the second sealing groove 422 to seal the second sealing ring 412, thereby sealing the connecting pipe 304, and the first sealing sleeve 420 is moved out from the first sealing groove 211, and the first sealing ring 209 is in an open state. Fig.11 As shown, the two micro hydraulic rods 504 are then simultaneously activated to push the arc plate 501 from the embedded groove 213 to the first sealing groove 211, and drive the sealing gasket 503 to move upward together, so that the outer surface of the first sealing sleeve 420 falls into the two grooves of the sealing gasket 503, as shown in FIG. Fig.11As shown, the first sealing groove 211 is protected. When the first sealing sleeve 420 moves outward, it will pass through the arc scraper 210. The arc scraper 210 will scrape the yellow phosphorus on the top of the first sealing sleeve 420 to the inside of the first sealing ring 209. Then, the negative pressure pump 201 is started to suck out the liquid yellow phosphorus in the nozzle body 105 and the threaded tube 104 through the suction pipe 202, enter the suction pipe 202, and then flow downward through the space between the first sealing sleeve 420 and the sealing gasket 503. Then, the yellow phosphorus continues to flow along the suction pipe 202 to the discharge pipe 205, and finally flows into the collecting tube 206 to collect the yellow phosphorus. After replacing the new nozzle body 105, the protection component 5 and the sealing component 4 are started again to reset the protection component 5. At this time, the output end of the forward and reverse motor 402 rotates in the opposite direction, driving the gear 404 to rotate in the opposite direction, and then driving the row of gears 406 to move toward the suction pipe 202, so that the first sealing sleeve 420 is reset and moves to the inside of the first sealing groove 211. Fig. 9 As shown, the first sealing ring 209 and one end of the suction pipe 202 are sealed, and the row of teeth 406 will pull the telescopic rod 410 apart. When the telescopic rod 410 is fully unfolded, the fixed block 411 and the second connecting block 413 will continue to be pulled to move, and the second sealing sleeve 415 will be further pulled out from the second sealing groove 422. At this time, the second sealing ring 412 and the inside of the connecting pipe 304 become a flow state, and the negative pressure pump 201 is started. The suction groove 308 is sucked through multiple suction pipes 307. The sucked gas enters the connecting pipe 304 through the annular pipe 303, and then enters the fixed pipe 306 through the flow meter 305. The gas flow is detected by the flow meter 305. When the gas flow does not match the set range value, it means that the connection between the nozzle body 105 and the threaded pipe 104 is not tight. In the subsequent use, there is a risk of yellow phosphorus leakage. The PLC controller 203 will control the alarm 204 to sound, reminding the staff that the nozzle body 105 needs to be reinstalled.

[0044] Among them, the solenoid valve 103, the nozzle body 105, the negative pressure pump 201, the alarm 204, the flow meter 305, the forward and reverse motor 402, the laser ranging sensor 408, the micro hydraulic rod 504 and the PLC controller 203 are all existing technologies, and their components and usage principles are all public technologies, so no excessive explanation will be given here.
