DETAILED DESCRIPTION

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figure 1-6 A phosphorus pentachloride feeding station includes a feeding station frame 1; the feeding station frame 1 is divided into a guide rail bracket 2, a waste bag collection chamber 3, an unpacking chamber 4 and a feeding chamber 5, the guide rail bracket 2 is located at the top of the feeding station frame 1, and a baffle 6 is provided on the bottom; the waste bag collection chamber 3, the feeding chamber 5 and the unpacking chamber 4 are interconnected, and are arranged in sequence from left to right directly below the guide rail bracket 2.

[0027] A guide rail 7 is laterally fixed to the top of the guide rail bracket 2, and a movable groove 8 parallel to the guide rail 7 is formed on the baffle 6. The system also includes an electric hoist 9 and a bag hanging device 10. The electric hoist 9 is installed on the guide rail 7, and the bag hanging device 10 is connected to the electric hoist 9 and is located below the movable groove 8. Since the waste bag collection chamber 3, the unpacking chamber 4 and the feeding chamber 5 are connected, the electric hoist 9 can drive the bag hanging device 10 to move freely among the three chambers, thereby driving the phosphorus pentachloride packaging bags to the required workstation.

[0028] In order to reduce manual operation and realize the automation of bag hanging and bag removal, and at the same time reduce the automation cost, the bag hanging device 10 has four bag hanging brackets 11 to maintain balance, and each of the bag hanging brackets 11 is connected to a self-locking hook 12 at the end thereof for hooking the bottom of the phosphorus pentachloride bag to facilitate subsequent unbundling and feeding; the self-locking hook 12 includes a fixed block 13, a hook 14 and a self-locking block 15, the fixed block 13 is movably connected to the hook 14, and the self-locking block 15 is movably connected to the hook 14; the upper end of the fixed block 13 has a triangular protrusion 1301, and the interior of the fixed block 13 is provided with a through slot 1302, the through slot A cylindrical limiting rod 16 is connected between 1302; one end of the hook 14 is a triangular limiting block 1401, an arc-shaped notch 1402 is provided near the limiting block 1401, and the other end is a solid hook tail 1403; the upper part of the self-locking block 15 is also provided with the through-notch 1302, the limiting rod 16 is connected between the through-notch 1302, the lower part is solid, and a self-locking groove 1501 is provided at the bottom; the limiting rod 16 inside the fixed block 13 passes through the arc-shaped notch 1402 of the hook 14, so that the hook 14 can slide back and forth, and the limiting rod 16 inside the self-locking block 15 passes through the triangular limiting block 1401, so that the self-locking block 15 can rotate.

[0029] The working principle of the self-locking hook 12 is as follows: when the self-locking hook 12 is in an unused state, the heavier self-locking block 15 drives the limit block 1401 to fall together. At this time, the hook tail 1403 at the other end of the hook 14 immediately rises. By simply lowering the self-locking hook 12 as a whole, the hook tail 1403 can be easily inserted into the bag ring at the bottom of the phosphorus pentachloride packaging bag specifically provided for feeding. At this time, the bag hanging device 10 rises, and the weight borne by the hook tail 1403 exceeds the weight of the self-locking block 15. Therefore, the hook tail 1403 falls, and the limit rod 16 at the fixed block 13 moves forward and slides toward the end of the through-notch 1302 near the limit block 1401. At the same time, the self-locking block 15 begins to rotate under the action of gravity, and the self-locking groove 1501 at the bottom contacts the hook tail 1403, achieving a closed and locked state. When the packaging bag needs to be removed from the self-locking hook 12, the hook tail 1403 is pressed down to contact an object, and the limiting rod 16 on the fixed block 13 is moved back to the end of the through-notch 1302 closer to the hook tail 1403. The triangular protrusion 1301 on the upper end of the fixed block 13 prevents the self-locking block 15 from becoming rigid and rotating. When the self-locking block 15 is at an angle greater than 45° to the horizontal, the protrusion 1301 pushes it downward, helping it to fall back and close.

[0030] The feeding chamber 5 is provided with a discharge port 17 inside. Below the discharge port 17, an outer sealed room 18 is formed by the baffle 6. A vibrating hopper 19 is fixed in the outer sealed room 18, and a nitrogen room 20 is provided below the vibrating hopper 19. The chamber also includes an iris valve 21 and a shutoff valve 22, which are respectively fixed to the lower end of the vibrating hopper 19 and the upper end of the nitrogen room 20. A discharge pipe 23 is connected to the bottom of the nitrogen room 20, a glove operation port 24 is provided on the side, and two opposing bag pressing cylinders 25 are provided on the inner side of the top. The chamber also includes a material cut-off ball valve 26 and a bag-beating device 27. The material cut-off ball valve 26 is connected to the bottom end of the discharge pipe 23 to facilitate controlling the direction of the material by opening or closing the material cut-off ball valve 26. The bag-beating device 27 is dispersed above the discharge port 17. A waste bag collecting frame 28 is placed at the bottom of the waste bag collecting chamber 3, and a liftable pressure plate 29 is provided on the side.

[0031] When the bag hanging device 10 brings the phosphorus pentachloride packaging bag to the feeding chamber 5, the phosphorus pentachloride packaging bag is still in an upside-down state, with the bag opening at the lower end tied tightly. At this time, the packaging bag slowly descends, passes through the discharge port 17 used for positioning, and contacts the vibrating bucket 19. The vibrating bucket 19 is equipped with a weighing sensor. After sensing the weight of the material, it stops descending. The iris valve 21 at the lower end of the vibrating bucket 19 and the isolation valve 22 at the upper end of the nitrogen room 20 are opened at the same time, so that the bag opening is inside the nitrogen room 20. At this time, the operator puts the bag opening onto the pipe openings of the loading and unloading pipes 23 through the glove operation port 24 sealed by the rubber glove, and presses the belts on both sides. The cylinder 25 pushes forward to tighten, and at the same time unties the bag opening and replaces the nitrogen from the outside through the vent and outlet below the nitrogen room 20. After completion, the pressing cylinder 25 withdraws the system to start unloading. During this process, the vibrating bucket 19 will vibrate to help unload the material, and the bag-beating devices 27 around it will also push and squeeze the packaging bag to help empty it. When the weighing sensor detects that the material has been emptied, the system will prompt the operator to tie the bag opening, and the bag hanging device 10 will bring the packaging bag to the waste bag collection chamber 3, press down on the waste bag collection frame 28 to achieve automatic unhooking, and the pressure plate 29 on the side will compact the waste bag, and the feeding is completed.

[0032] In order to improve the corrosion resistance of the entire device and extend its service life, the feeding station frame 1 is made of carbon steel frame and is surrounded by baffles 6. The baffles 6 are made of PE plates.

[0033] In order to close the device in time, automatic doors 30 are provided at the bottom of the waste bag collecting chamber 3 and the unpacking chamber 4 .

[0034] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
