Technical Field

[0001] The invention relates to the technical field of conveying devices, and in particular to an intelligent conveying device and a material receiving and conveying system for fluorine chemical industry. Background Art

[0002] In the fluorine chemical production process, the collection and storage of raw materials is a key link, which is directly related to production efficiency and product quality.

[0003] Fluorine chemical industry uses sealed pipes and containers, and adds liquid nitrogen into the container to generate a pressure difference. The low temperature characteristics of liquid nitrogen can reduce the air pressure in the container, thereby generating a pressure difference. Under the action of the pressure difference, the fluorine chemical raw materials will smoothly enter the receiving container through the receiving pipe. In order to ensure the stable collection of raw materials, the discharge of liquid nitrogen is usually intermittent and quantitative.

[0004] In the fluorine chemical production process, the transportation and transfer of raw materials is an important link, which is related to production efficiency and safety. The existing transportation method uses a conveyor belt to transport containers containing raw materials. However, during the transportation process, due to the stretching of the conveyor belt, the tension and length of the conveyor belt will change, resulting in bumps and setbacks in the transportation process, and the conveyor belt will become loose after long-term use. The roller spacing of the existing conveyor belt is generally fixed and difficult to adjust, which will affect safety and transportation efficiency. Summary of the invention

The torsion spring is connected to the mounting rod and is used for applying a torque opposite to the swinging direction of the mounting rod to the mounting rod.

[0010] Furthermore, the transmission mechanism also includes an acceleration gear, a mounting frame, a gear ring and a rotating shaft; The mounting rod is hinged to the mounting frame, one end of the torsion spring is connected to the mounting rod, and the other end is connected to the mounting frame; The rotating shaft is rotatably mounted on the mounting rod, the accelerating gear is mounted on the rotating shaft and meshes with the gear ring, and the tightening tooth is rotatably mounted on the rotating shaft via a one-way bearing; When the mounting rod swings in a direction in which the tilt angle increases, the acceleration gear is driven to roll along the gear ring, and then the acceleration gear drives the rotating shaft and the tensioning teeth to rotate.

[0011] Furthermore, it comprises two transmission mechanisms, and the two transmission mechanisms are respectively used to connect the motor and the two rollers.

[0012] Furthermore, it also includes a reset mechanism, which includes a second rack and a tension spring; The second rack is meshed with the driving gear, and the tension spring is connected to the second rack to drive the second rack to move so as to drive the driving gear to rotate in the opposite direction, thereby causing the driving gear to drive the two rollers to approach each other.

[0021] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Example 1, reference Figure 1 and Figure 2 A fluorine chemical intelligent conveying device includes a supporting mechanism 500, and the supporting mechanism 500 includes a supporting leg 510 and a pad connected to the top of the supporting leg 510.

[0025] Reference Figure 3 and Figure 4A conveying mechanism 600 is arranged on the supporting mechanism 500, and the conveying mechanism 600 includes two slides 620 located on both sides of the two legs 510, and a through slot matched with the slide 620 is opened on the leg 510, and a motor 610 is fixedly arranged between the two legs 510, and the motor 610 can be installed on the ground or fixedly connected to the leg 510, and the output end of the motor 610 is connected to the driving gear 660 through the magnetic coupler 670, and the two slides 620 are connected to the roller seat 630 and the first rack 621, and the roller 640 is rotatably connected to the roller seat 630, and the two first racks 621 are symmetrically located on both sides of the driving gear 660 and meshed with the driving gear 660, and a conveyor belt 650 is transmission-connected between the two rollers 640, and the motor 61 0 Start up and drive the driving gear 660 to rotate through the magnetic coupling 670. The driving gear 660 drives the first rack 621 to slide so that the two slide seats 620 move away from each other, so that the conveyor belt 650 is tightened. Multiple storage mechanisms 100 and their corresponding exhaust mechanisms 200 are placed on the conveyor belt 650. After the front storage mechanism 100 collects the full fluorine chemical, the conveyor belt 650 is tightened and then runs. The next storage mechanism 100 is switched to move to the position of the previous storage mechanism 100 to take over the collection. By setting the conveyor belt 650 to be tightened during transportation and not loosened in the transportation state, it is ensured that the conveyor belt 650 is not easily deformed and stretched, resulting in inaccurate transportation distance and slippage between the conveyor belt 650 and the roller 640. Reference Figure 5 The conveying mechanism 600 is driven by a transmission mechanism 700. There are two transmission mechanisms 700. The two transmission mechanisms 700 are driven by a motor 610, and the two transmission mechanisms 700 drive two rollers 640 to rotate respectively. The transmission mechanism 700 includes two groups of transmission gears 710. The two transmission gears 710 in each group are respectively connected to the output end of the motor 610 and the roller 640. Each group of transmission gears 710 is connected by a chain 720. After the motor 610 is started, the conveyor belt 650 is first driven to tighten through the magnetic coupling 670. When the conveyor belt 650 is tightened, the motor 610 idles on the driving gear 660, but the magnetic force of the magnetic coupling 670 makes the driving gear 660 have a tendency to rotate, ensuring that the conveyor belt 650 is always in a tightened state. At this time, the running motor 610 drives the roller 640 to rotate through the transmission gear 710 and the chain 720, so that the conveyor belt 650 runs; Reference Figure 5The transmission mechanism 700 further includes a mounting frame 730 connected to the support leg 510, and a rotating rod 741 is rotatably connected to the mounting frame 730 through a torsion spring 750, and the end of the rotating rod 741 is connected to the mounting rod 740, and both ends of the mounting rod 740 are rotatably connected to tightening teeth 760. When the distance between the two transmission gears 710 increases, the middle parts of the chain 720 approach each other, so that the mounting rod 740 is pushed to swing around the rotating rod 741 through the tightening teeth 760. At this time, the torsion spring 750 is subjected to a torsion force, and the mounting rod 740 is not in a vertical state in the initial state. Therefore, when the middle parts of the chain 720 approach each other, the mounting rod 740 can swing toward its original tilt direction; Reference Figure 5 , the mounting rod 740 is rotatably connected with an acceleration gear 770, and the mounting frame 730 is connected with a toothed ring 780 meshing with the acceleration gear 770. The middle part of the acceleration gear 770 has a shaft penetrating the mounting rod 740, and the end of the shaft is connected to the tensioning tooth 760 through a one-way bearing. During the transmission process of the chain 720 driven by the motor 610, the tensioning tooth 760 can rotate relative to the acceleration gear 770, and when the conveyor belt 650 is deformed and elongated, the middle parts of the chain 720 are close to each other so that the mounting rod 740 swings, so that the acceleration gear 770 rolls on the toothed ring 780, and at this time, the acceleration gear 770 drives the tensioning tooth 760 to rotate, instantly increasing the transmission speed of the chain 720, so that when the conveyor belt 650 is deformed and elongated, the objects it transmits can be quickly displaced to compensate for the distance error caused by the deformation of the conveyor belt 650; Reference Figure 6 The support leg 510 is connected to a support plate 520, which supports the conveyor belt 650 to reduce the deformation degree of the conveyor belt 650 under pressure. The lower surface of the support plate 520 is provided with a reset mechanism 800, which includes a second driving rack 830, a round rod 820 is connected to the second driving rack 830, a fixed seat 810 and an electromagnet 840 are connected to the lower surface of the support plate 520, and the round rod 820 slides on the fixed seat 810. A tension spring 850 is connected between the fixed seat 810 and the second driving rack 830, and the electromagnet 840 is electrically connected to the motor 610. When the motor 6 10 When starting, the electromagnet 840 is energized synchronously to adsorb the driving second rack 830. At this time, the driving second rack 830 drives the driving gear 660 to rotate. At this time, the rotation of the driving gear 660 can drive the two slides 620 to move away from each other. When the transportation is completed, the motor 610 is powered off. At this time, the electromagnet 840 releases the driving second rack 830, and the tension spring 850 pulls the driving second rack 830 to reset. At this time, the driving second rack 830 drives the driving gear 660 to rotate. At this time, the rotation of the driving gear 660 can drive the two slides 620 to move closer to each other, and the conveyor belt 650 is no longer tightened.

[0026] Example 2, reference Figure 1 , Figure 7-Figure 16 A fluorine chemical material receiving container, comprising a storage mechanism 100 and an exhaust mechanism 200, wherein the storage mechanism 100 comprises a receiving cylinder 120, the receiving cylinder 120 is connected with a receiving pipe 410 and an adding pipe 250, the exhaust mechanism 200 comprises a pressure stabilizing cylinder 210, a circular plate 220 is slidably connected in the pressure stabilizing cylinder 210, the bottom of the pressure stabilizing cylinder 210 is connected with a pressure stabilizing pipe 230, and a valve is arranged on the pressure stabilizing pipe 230; the top of the pressure stabilizing cylinder 210 is connected with a dual-purpose pipe 2 40. The dual-purpose tube 240 is connected to the adding tube 250 through the first electromagnetic three-way valve 251. When the air pressure in the accommodating tube 120 increases, the first electromagnetic three-way valve 251 operates to connect the adding tube 250 to the dual-purpose tube 240, so that the circular plate 220 moves downward due to gravity to reduce the air pressure in the accommodating tube 120. After the air pressure in the accommodating tube 120 is reduced, the first electromagnetic three-way valve 251 operates to interrupt the connection between the dual-purpose tube 240 and the adding tube 250.

[0027] The working mechanism of the fluorine chemical material receiving container provided in this embodiment is as follows: When in use, the receiving tube 410 is connected to the fluorine chemical production equipment, and after checking the sealing of the receiving tube 410 and the receiving tube 120, liquid nitrogen is added into the receiving tube 120 through the adding tube 250, so that the air pressure in the receiving tube 120 is reduced, and a pressure difference is generated, so that the fluorine chemical enters the receiving tube 120 through the receiving tube 410 under the action of the pressure difference, and the liquid nitrogen is intermittently and quantitatively discharged into the receiving tube 120. After the air pressure in the receiving tube 120 increases, the liquid nitrogen is introduced into the receiving tube 120 again; When the pressure in the containing cylinder 120 decreases, the first electromagnetic three-way valve 251 controls the dual-purpose pipe 240 to not communicate with the adding pipe 250, thereby avoiding the pressure difference acting in the pressure-stabilizing cylinder 210, ensuring that the fluorine chemical can be stably collected. The liquid nitrogen supply device is provided with a dedicated control valve, which can control the communication between the liquid nitrogen supply device and the adding pipe 250; After the pressure in the containing cylinder 120 increases, the pressure difference between the containing cylinder 120 and the fluorine chemical production device decreases or disappears. At this time, the first electromagnetic three-way valve 251 controls the dual-purpose tube 240 to be connected with the addition tube 250. At this time, the pressure-stabilizing cylinder 210 is connected with the containing cylinder 120, and the valve on the pressure-stabilizing tube 230 is in an open state. The circular plate 220 moves downward relative to the pressure-stabilizing cylinder 210 due to gravity, so that the high pressure after the temperature in the containing cylinder 120 is increased is released into the pressure-stabilizing cylinder 210. Then the first electromagnetic three-way valve 251 cuts off the connection between the dual-purpose tube 240 and the addition tube 250 to ensure that when liquid nitrogen is subsequently injected into the containing cylinder 120, negative pressure can continue to be generated inside the containing cylinder 120.

[0028] Regarding the structure of the storage mechanism 100, specifically: The storage mechanism 100 also includes a support tube 110 , a clamping block 121 is provided on the outer wall of the accommodating tube 120 , and an arc strip 111 is connected to the inner wall of the support tube 110 . When the accommodating tube 120 is inserted into the support tube 110 and rotated, the clamping block 121 is clamped on the arc strip 111 .

[0029] When fixing the accommodating cylinder 120, insert the accommodating cylinder 120 into the supporting cylinder 110 so that the upper and lower end surfaces of the accommodating cylinder 120 are respectively flush with the upper and lower end surfaces of the supporting cylinder 110, and then rotate the accommodating cylinder 120 so that the blocking block 121 on the accommodating cylinder 120 is engaged with the arc-shaped bar 111, so that when the accommodating cylinder 120 contracts due to the addition of liquid nitrogen, the supporting cylinder 110 pulls the outer wall of the accommodating cylinder 120, so that the strength of the accommodating cylinder 120 is guaranteed.

[0030] Regarding the structure of the pressure monitoring mechanism 400, specifically: The pressure monitoring mechanism 400 includes a mounting cylinder 420 , which is connected to the receiving tube 410 , an inner conical cylinder 421 is connected inside the mounting cylinder 420 , a conical rod 422 is slidably connected inside the inner conical cylinder 421 , and a spring 440 is connected between the conical rod 422 and the inner conical cylinder 421 .

[0031] When the internal pressure of the accommodating cylinder 120 decreases, the fluorine chemical pushes the conical rod 422 under the action of the pressure difference, so that the conical rod 422 breaks away from the contact with the inner conical cylinder 421. At this time, a gap is generated between the two, so that the fluorine chemical enters the accommodating cylinder 120 through the receiving tube 410, and the spring 440 provides an auxiliary force for the reset of the conical rod 422. When the pressure difference between the accommodating cylinder 120 and the fluorine chemical equipment decreases, the fluorine chemical will no longer push the conical rod 422. At this time, the excess gas in the accommodating cylinder 120 is discharged and then liquid nitrogen is injected into the accommodating cylinder 120 to continue to collect the fluorine chemical.

[0032] Among the optional methods of this embodiment, the more preferred ones are: The pressure monitoring mechanism 400 further includes a slide rod 430 . A slide frame 431 is connected to the receiving tube 410 . The slide rod 430 slides in the slide frame 431 .

[0033] The mutual cooperation between the slide rod 430 and the slide frame 431 enables an annulus to be generated between the conical rod 422 after the conical rod 422 is separated from the inner conical cylinder 421 , thereby ensuring that the fluorine chemical can flow in the receiving tube 410 and enter the containing cylinder 120 .

[0034] Among the optional methods of this embodiment, the more preferred ones are: The pressure monitoring mechanism 400 also includes a magnetic ring 460 that is slidably sleeved on the receiving tube 410, and the end of the sliding rod 430 is connected to a ferromagnetic block 450 that is magnetically attracted to the magnetic ring 460. The outer wall of the mounting tube 420 is connected to a switch. When the sliding rod 430 slides back and forth on the sliding frame 431, the magnetic ring 460 slides back and forth and repeatedly presses the switch, so that the first electromagnetic three-way valve 251 controls the addition tube 250 to be connected with the accommodating tube 120, and after the magnetic ring 460 stops sliding back and forth, the magnetic ring 460 continues to press the switch, so that the first electromagnetic three-way valve 251 controls the voltage-stabilizing tube 230 to be connected with the accommodating tube 120.

[0035] When the slide bar 430 slides, it can drive the magnetic ring 460 to slide synchronously through the ferromagnetic block 450. If the pressure in the accommodating cylinder 120 is low, the pressure difference will cause the conical rod 422 to slide back and forth. At this time, the magnetic ring 460 is driven to slide back and forth synchronously, so that the magnetic ring 460 repeatedly presses the switch on the mounting cylinder 420. When the control system detects that the switch is repeatedly pressed, the first electromagnetic three-way valve 251 is in a state of controlling the dual-purpose tube 240 not to be connected with the addition tube 250. As the pressure difference disappears, the conical rod 422 no longer slides, so that the magnetic ring 460 is in a state of constantly pressing the switch. When the control system detects that the switch is kept pressed, the first electromagnetic three-way valve 251 controls the dual-purpose tube 240 to be connected with the addition tube 250, so that the excess gas in the accommodating cylinder 120 is discharged. When the circular plate 220 continues to move downward to restore the air pressure in the accommodating tube 120, the air pressure pulls the conical rod 422 to slide, causing the magnetic ring 460 to break contact with the switch, so that the control system controls the operation of the first electromagnetic three-way valve 251, so that the dual-purpose tube 240 is connected and disconnected from the addition tube 250.

[0036] Among the optional methods of this embodiment, the more preferred ones are: The outer wall of the receiving tube 410 is connected with a mounting ring 480 , the magnetic ring 460 is connected with an insertion rod 470 , and the mounting ring 480 is provided with a sliding hole that cooperates with the insertion rod 470 .

[0037] The cooperation between the insert rod 470 and the mounting ring 480 positions the sliding direction of the magnetic ring 460 , thereby preventing the magnetic ring 460 from getting stuck on the receiving tube 410 .

[0038] Regarding the structure of the protection mechanism 300, specifically: The protection mechanism 300 includes a plurality of piston assemblies 310 arrayed in the support tube 110 . The plurality of piston assemblies 310 are all in contact with the outer wall of the accommodating tube 120 . When the accommodating tube 120 is deformed, the piston assemblies 310 further expand and contract.

[0039] The piston assembly 310 includes a piston rod, a piston cylinder and an elastic component connected therebetween. After the accommodating cylinder 120 is inserted into the supporting cylinder 110, the piston rod slides to a middle position in the piston cylinder. If the accommodating cylinder 120 is deformed due to negative pressure, some of the piston rods of the multiple piston assemblies 310 are pushed to slide inside the piston cylinder, while others are pushed to slide outside the piston cylinder by the elastic component. At this time, it can be reflected whether the accommodating cylinder 120 is deformed.

[0040] Among the optional methods of this embodiment, the more preferred ones are: The protection mechanism 300 also includes two control boxes 340. The piston assembly 310 is connected to an intake pipe 320 and an exhaust pipe 330. Both the intake pipe 320 and the exhaust pipe 330 are provided with one-way valves. The ends of the intake pipe 320 and the exhaust pipe 330 are connected to the control box 340. When the piston assembly 310 is extended or retracted, it can discharge or extract air into the two control boxes 340 respectively; an air duct 350 is connected between the two control boxes 340, and a connecting valve 360 ​​is provided on the air duct 350.

[0041] When the piston assembly 310 is extended or retracted, the internal air can be discharged into the control box 340 through the exhaust pipe 330, or the air in the control box 340 can be extracted through the intake pipe 320, so that the air pressure in the two control boxes 340 changes. After the connecting valve 360 ​​is opened, the air guide pipe 350 is connected with the two control boxes 340, so that after the accommodating cylinder 120 is moved out of the supporting cylinder 110, the piston assembly 310 returns to its original length, and the air pressure in the two control boxes 340 returns to its original state.

[0042] Among the optional methods of this embodiment, the more preferred ones are: A rectangular plate 341 is slidably connected inside the control box 340, a return spring 342 is connected between the rectangular plate 341 and the control box 340, a C-shaped frame 344 is connected to the outer wall of the control box 340, a pressure-sensitive switch 345 is provided on the C-shaped frame 344, a rectangular rod 343 is connected to the rectangular plate 341, and when the rectangular plate 341 slides, the rectangular rod 343 can abut against the pressure-sensitive switch 345.

[0043] When the gas enters and exits the corresponding control box 340, the rectangular plate 341 can slide in the control box 340, so that the rectangular rod 343 connected to the rectangular plate 341 can approach and squeeze the pressure sensitive switch 345, and then the fluorine chemical in the containing cylinder 120 is transferred to the pressure stabilizing cylinder 210.

[0044] Among the optional methods of this embodiment, the more preferred ones are: The protection mechanism 300 also includes a stabilizing tube 370 connected to the accommodating cylinder 120, a first solenoid valve 371 is arranged on the stabilizing tube 370, a second solenoid valve 252 is arranged on the adding tube 250, a transfer tube 380 is connected between the adding tube 250 and the receiving tube 410, and a second solenoid three-way valve 381 is arranged at the connection between the transfer tube 380 and the receiving tube 410. When any pressure-sensitive switch 345 is pressurized, the first solenoid valve 371 is opened and the second solenoid valve 252 is closed, and the first solenoid three-way valve 251 and the second solenoid three-way valve 381 are both in operation, so that external air enters the accommodating cylinder 120 through the stabilizing tube 370, and the material in the accommodating cylinder 120 is transferred to the pressure-stabilizing cylinder 210 by the receiving tube 410, the transfer tube 380, the adding tube 250 and the dual-purpose tube 240.

[0045] When any pressure-sensitive switch 345 is pressurized, the first solenoid valve 371 opens, the second solenoid three-way valve 381 controls the material receiving tube 410 to be connected with the transfer tube 380, the transfer tube 380 is connected with the adding tube 250, and the first solenoid three-way valve 251 controls the dual-purpose tube 240 to be connected with the adding tube 250. At this time, the fluorine chemical production equipment is no longer connected with the containing cylinder 120 through the material receiving tube 410, so that the circular plate 220 moves downward due to gravity, so that negative pressure is generated in the pressure-stabilizing cylinder 210, so that external air enters the containing cylinder 120 through the stabilizing tube 370, and the fluorine chemical in the containing cylinder 120 enters the pressure-stabilizing cylinder 210 through the material receiving tube 410, the transfer tube 380, the adding tube 250 and the dual-purpose tube 240, so that the fluorine chemical in the deformed containing cylinder 120 is transferred to the pressure-stabilizing cylinder 210, so as to avoid the deformation and rupture of the containing cylinder 120, which leads to a large amount of leakage of fluorine chemical.
