Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of red phosphorus production equipment, and in particular relates to a red phosphorus packaging machine. Background Technology
[0002] Currently, the production process for red phosphorus is as follows: yellow phosphorus → melting in a pot → high-temperature conversion → ball milling → alkaline boiling → washing → centrifugal dehydration → vacuum drying → packaging and warehousing. The conversion principle is as follows: Yellow phosphorus is heated to approximately 295℃-300℃ for an extended period in the absence of air, converting it into red phosphorus. After grinding and alkaline boiling, followed by washing, dehydration, and drying, the finished red phosphorus is obtained. The entire red phosphorus production process consists of conversion, ball milling, alkaline boiling, washing, dehydration, drying, and packaging. After preparation, red phosphorus needs to be packaged for easy transportation; currently, the most common packaging method is bagging.
[0003] For example, patent document CN221050002U discloses a packaging device for phosphorus oxychloride, including a mounting plate. A conveying pipe is installed on the side wall of the mounting plate. The conveying pipe has multiple right-angle bends. A nozzle is installed at the lower end of the conveying pipe. A lifting device is installed below the nozzle. A pair of connecting blocks are installed on the lifting device. Each pair of connecting blocks has a slide rail. A slider is slidably connected in the slide rail. A support plate is fixedly connected to the slider. A limit ring is provided on the support plate. A packaging barrel is placed in the limit ring. Using this patented technology, the packaging barrel is raised by the lifting platform, so that the nozzle on the conveying pipe enters the packaging barrel to convey phosphorus oxychloride into the packaging barrel. After conveying, the lifting platform descends, and the packaging barrel separates from the nozzle. This eliminates the need for operators to contact the conveying pipe during packaging, thereby reducing the risk of operators coming into contact with phosphorus oxychloride. However, the above-mentioned patented technology is not applicable to the bagging of red phosphorus, mainly because red phosphorus has an extremely low ignition point. If the temperature is slightly high, it is prone to explosive combustion in a confined environment, leading to production accidents and posing a high safety risk. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a red phosphorus packaging machine.
[0005] This utility model provides a red phosphorus packaging machine, including a material bin, a guide pipe, and an air inlet pipe. The top of the material bin is provided with a feeding port, and the bottom of the material bin is connected to one end of the guide pipe. The other end of the guide pipe is fixedly connected to a discharge valve. One end of the air inlet pipe extends into the material bin, and the other end of the air inlet pipe is connected to an inert gas source. The air inlet pipe is also fixedly connected to a control valve. The control terminals of the discharge valve and the control valve are both electrically connected to a controller.
[0006] The red phosphorus packaging machine also includes a frame, the material bin is fixed to the top of the frame, the controller is fixed to the side of the frame, and a bag clamp is also provided inside the frame. The bag clamp is located below the material discharge valve, and the bag clamp corresponds to the material discharge valve one by one.
[0007] The frame is also equipped with a support platform, which is located below the bag clamp and corresponds one-to-one with the bag clamp. A weighing sensor is also installed at the bottom of the support platform and is electrically connected to the controller.
[0008] The side of the frame is also fixedly connected to the purification chamber, which is also equipped with a vacuum cleaner. The control terminal of the vacuum cleaner is electrically connected to the controller.
[0009] The red phosphorus packaging machine also includes a spray pipe, one end of which is connected to a fire water source, and the other end of which extends into the material hopper. The spray pipe is also fixedly connected to a water control valve, which is electrically connected to the controller.
[0010] The material hopper is also equipped with a material distribution plate, one end of which is close to the feed inlet and the other end of which is close to the guide pipe.

[0012] A pressure gauge is also installed on the top of the hopper.
[0013] The controller can be replaced by a programmable logic controller or a microcontroller.
[0014] The feed tube is a frustum-shaped cone with an upper port diameter larger than the lower port diameter.
[0015] The beneficial effects of this utility model are as follows: Using the technical solution provided by this utility model, solid powdered red phosphorus is fed into the material hopper through the feed inlet. The controller, through its built-in program, first drives the gas control valve to open, sending a low-temperature inert gas into the material hopper, preferably nitrogen. Then, the discharge valve is opened, allowing the red phosphorus in the material hopper to fall into the packaging bag, thus completing the bagging of the red phosphorus. Since the material hopper is pre-filled with inert gas, the red phosphorus is prevented from contacting oxygen, thus preventing the red phosphorus from burning in the material hopper, eliminating safety hazards, and avoiding safety accidents.

Detailed Implementation
[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings, but the scope of protection claimed is not limited to the description.
[0020] This utility model provides a red phosphorus packaging machine, such as Figures 1 to 2 As shown, it includes a material hopper 1, a guide pipe 2, and an air inlet pipe 3. The top of the material hopper 1 is provided with a feed inlet 4. The bottom of the material hopper 1 is connected to one end of the guide pipe 2. The other end of the guide pipe 2 is fixedly connected to the discharge valve 5. One end of the air inlet pipe 3 extends into the material hopper 1. The other end of the air inlet pipe 3 is connected to an inert air source. The air inlet pipe 3 is also fixedly connected to the air control valve 6. The control end of the discharge valve 5 and the control end of the air control valve 6 are both electrically connected to the controller 7.
[0021] Using the technical solution provided by this utility model, solid powdered red phosphorus is fed into the material hopper through the feed inlet. The controller, through its built-in program, first drives the gas control valve to open, sending a low-temperature inert gas into the material hopper, preferably nitrogen. Then, the discharge valve is opened, allowing the red phosphorus in the material hopper to fall into the packaging bag, completing the bagging of the red phosphorus. Because the material hopper is pre-filled with inert gas, the red phosphorus is prevented from contacting oxygen, thus preventing combustion of the red phosphorus in the material hopper, eliminating safety hazards, and avoiding safety accidents.
[0022] Specifically, the red phosphorus packaging machine also includes a frame 8, a material bin 1 fixedly connected to the top of the frame 8, a controller 7 fixedly connected to the side of the frame 8, and a bag clamp 9 installed inside the frame 8. The bag clamp 9 is located below the material discharge valve 5, and the bag clamp 9 corresponds one-to-one with the material discharge valve 5. Using the technical solution of this utility model, the bag clamp 9 is used to clamp the opening of the packaging bag, giving the packaging bag a stable position, thereby allowing the solid powdered red phosphorus to fall stably into the packaging bag, completing the bagging of the red phosphorus.
[0023] In addition, a support platform 10 is provided inside the frame 8. The support platform 10 is located below the bag clamp 9, and the support platform 10 corresponds one-to-one with the bag clamp 9. A weighing sensor 11 is also installed at the bottom of the support platform 10, and the weighing sensor 11 is electrically connected to the controller 7. Using the technical solution of this utility model, the weighing sensor 11 is used to measure the weight of the packaging bag and the red phosphorus filled inside. When the weight meets the packaging requirements, the controller automatically controls the discharge valve 5 to close, so that the weight of each bag of red phosphorus is consistent.
[0024] Specifically, the side of the frame 8 is also fixedly connected to the purification chamber 12, and a vacuum cleaner 13 is installed inside the purification chamber 12. The control terminal of the vacuum cleaner 13 is electrically connected to the controller 7. Using the technical solution of this utility model, dust inevitably occurs inside the frame during the red phosphorus packaging process. When personnel move inside the frame, the dust adheres to the surface of their clothing. When needed, personnel can enter the purification chamber 12 and use the vacuum cleaner 13 to remove the dust adhering to their clothing, thus purifying their bodies and clothing.
[0025] In addition, the red phosphorus packaging machine also includes a spray pipe 14. One end of the spray pipe 14 is connected to a fire water source, and the other end extends into the material bin 1. The spray pipe 14 is also fixedly connected to a water control valve 15, which is electrically connected to the controller 7. Using this invention, if the red phosphorus inside the material bin 1 ignites, the controller can also drive the water control valve 15 to open, spraying fire water into the material bin 1 to extinguish the fire promptly, ensuring the safe and stable operation of the packaging machine and preventing accidents.
[0026] Specifically, the material hopper 1 is also equipped with a distribution plate 16. One end of the distribution plate 16 is close to the feed inlet 4, and the other end of the distribution plate 16 is close to the guide pipe 2. Using the technical solution of this utility model, the distribution plate 16 is used to uniformly divide the solid powdered red phosphorus in the material hopper 1 according to weight or flow rate, so that the weight of red phosphorus filled in each packaging bag is basically consistent.
[0027] In addition, the top of the material compartment 1 is connected to one end of the exhaust pipe 17, and the other end of the exhaust pipe 17 extends vertically upward. A pressure gauge 18 is also installed on the top of the material compartment 1. The controller 7 can be replaced by a programmable logic controller or a microcontroller. Using the technical solution of this utility model, the operator can also obtain the air pressure information inside the material compartment 1 through the pressure gauge 18. On the one hand, when the air pressure inside the material compartment is too high, the exhaust pipe 17 will be opened in time to reduce the pressure inside the material compartment 1; on the other hand, when the air pressure inside the material compartment is too low, the controller will open the air control valve 6 in time to fill the material compartment with an appropriate amount of inert gas, ensuring the safe and stable operation of the packaging machine and avoiding safety accidents.
[0028] Specifically, the feed tube 2 is a frustum-shaped cone with an upper port diameter larger than the lower port diameter. Preferably, there are three or more feed tubes 2. A vibrator 19 is also installed on the surface of the feed tube 2. The vibrator 19 is electrically connected to the controller 7. The vibrator 19 is used to beat the feed tube 2 to prevent solid powdered red phosphorus from clogging or getting stuck inside the feed tube 2.
