Description

Technical Field

[0001] This utility model relates to the field of breathing gas treatment technology, specifically a breathing gas treatment device for a diphenylphosphine chloride storage tank. Background Technology

[0002] The primary function of diphenylphosphine chloride storage tanks is to store diphenylphosphine chloride, preventing it from being directly exposed to air and reacting with oxygen, moisture, and other substances in the air, thereby maintaining its purity and stability. The tanks are typically airtight, effectively isolating diphenylphosphine chloride from the influence of the external environment.

[0003] During the transport of diphenylphosphine chloride, the volume of the gas phase space inside the storage tank changes, leading to changes in the gas pressure inside the tank. A breathing assembly needs to be installed on the storage tank to maintain pressure balance inside the tank and ensure storage safety. However, existing diphenylphosphine chloride storage tanks do not facilitate the purification of the emitted gas, and direct discharge into the air will cause environmental pollution. To address the above problems, the inventors propose a breathing gas treatment device for diphenylphosphine chloride storage tanks to solve the aforementioned issues. Utility Model Content

[0004] To address the problem of inconvenient gas purification during the emission of gases from diphenylphosphine chloride storage tanks, the purpose of this invention is to provide a breathing gas treatment device for diphenylphosphine chloride storage tanks.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a breathing gas treatment device for a diphenylphosphine chloride storage tank, comprising a storage tank body, an installation plate fixedly provided on the outer surface of the storage tank body, a treatment box fixedly provided on the top surface of the installation plate, a connecting pipe fixedly provided on one side of the treatment box, one end of the connecting pipe fixedly inserted into the storage tank body, and a discharge pipe fixedly provided on the side of the treatment box away from the connecting pipe, wherein a filter screen is installed inside the discharge pipe;

[0006] A fixed plate is installed inside the processing box. A motor is installed on one side of the fixed plate. A threaded rod is fixedly installed at the output end of the motor. A threaded plate is threadedly fitted on the outer surface of the threaded rod. Movable plates are fixedly installed on both sides of the threaded plate. A baffle is fixedly installed on one side of the movable plate. A first sealing strip is fixedly fitted on the outer surface of the baffle. The baffle and the first sealing strip are movably inserted into the fixed plate. A U-shaped plate is fixedly installed on one side of the fixed plate. One end of the threaded rod is rotatably connected to the U-shaped plate. The threaded plate is slidably fitted on the outer surface of the U-shaped plate. A through groove is opened in the fixed plate. The baffle and the first sealing strip are slidably inserted into the through groove. First, after the feed pipe is connected to the external pipe, diphenylphosphine chloride is stored in the storage tank. At this time, while the storage tank is transporting and storing diphenylphosphine chloride, pressure is generated inside it. Then, by turning on the motor, the threaded rod rotates, which causes the threaded plate to drive the movable plate to slide, and causes the baffle and the first sealing strip to disengage from the through groove. At the same time, the waste gas is purified by the activated carbon plate, so that the waste gas can be discharged.

[0007] Then, after the discharge pipe is connected to the external pipeline, diphenylphosphine chloride is discharged from the storage tank body, creating a negative pressure inside the storage tank body. At the same time, the motor is turned on again, causing the threaded rod to rotate, which in turn causes the threaded plate to slide along the moving plate, and causes the baffle and the first sealing strip to disengage from the through groove. This allows air to enter the processing box from the discharge pipe and be transported into the storage tank body. The air passes through the filter screen to filter out dust and impurities in the air.

[0008] By pulling the two sets of limiting components, the slider slides on the outer surface of the slide rod and compresses the spring, thereby causing the limiting components to disengage from the positioning groove. This separates the two sets of limiting components, allowing the connecting plate and activated carbon plate to be disassembled and replaced. After replacement, the activated carbon plate is reinserted into the second sealing strip, and then the limiting components are released, causing the spring to return to its original position. The limiting components then slide back into the positioning groove, causing the two limiting components to come into contact. This effectively presses and limits the connecting plate and activated carbon plate, preventing untreated exhaust gas from being emitted between the second sealing strip and the connecting plate, thus avoiding air pollution.

[0009] Preferably, a frame is fixedly provided on one side of the fixed plate, a limiting block is fixedly provided on one side of the movable plate, the limiting block is slidably disposed within the frame, a limiting rod is fixedly provided within the frame, and the limiting block is slidably sleeved within the limiting rod.

[0010] Preferably, a second sealing strip is fixedly provided inside the processing box, a connecting plate is provided above the processing box, an activated carbon plate is fixedly provided on the bottom surface of the connecting plate, the activated carbon plate slides through the second sealing strip, a limiting member is slidably provided above the processing box, a positioning groove is provided inside the connecting plate, the limiting member is slidably provided in the positioning groove, an insert is fixedly provided on one side of the limiting member, the insert is slidably inserted into the limiting member, a sliding groove is provided inside the processing box, a sliding rod is fixedly provided in the sliding groove, a slider is fixedly provided on the bottom surface of the limiting member, the slider is slidably sleeved on the outer surface of the sliding rod, and a spring is fixedly provided between the slider and the sliding groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. By sliding the movable plate, the baffle and the first sealing strip are disengaged from the through groove, so that the exhaust gas can be discharged or the air can be discharged into the storage tank. At the same time, when the exhaust is discharged, the exhaust gas is purified by the activated carbon plate. When the air is inhaled, the air passes through the filter screen to filter the dust and impurities in the air, so that the gas can be purified for discharge and avoid pollution to the environment.

[0013] 2. By inserting the activated carbon plate into the second sealing strip and then releasing the limiting member, the spring is reset, which in turn resets the limiting member and slides it in the positioning groove, thereby making the two limiting members fit together. This allows the connecting plate and the activated carbon plate to be pressed and limited, preventing untreated waste gas from being emitted between the second sealing strip and the connecting plate, thus avoiding air pollution.

A through groove 301 is provided inside the fixed plate 3. The baffle 36 and the first sealing strip 37 are slidably inserted into the through groove 301. During storage or retrieval, the motor 32 is powered by an external power source. By turning on the motor 32, the threaded rod 33 rotates, which in turn causes the threaded plate 34 to drive the moving plate 35 to slide, and causes the baffle 36 and the first sealing strip 37 to disengage from the through groove 301, thereby allowing the exhaust gas to be discharged or the air to be discharged into the storage tank body 1. At the same time, during exhaust, the exhaust gas is purified by the activated carbon plate 41. During intake, the air passes through the filter screen 24 to filter the dust and impurities in the air, thereby purifying the gas for discharge and avoiding environmental pollution.

[0027] A frame 38 is fixedly provided on one side of the fixed plate 3, and a limiting block 351 is fixedly provided on one side of the movable plate 35. The limiting block 351 is slidably disposed within the frame 38, and a limiting rod 39 is fixedly provided within the frame 38. The limiting block 351 is slidably sleeved within the limiting rod 39.

[0028] By adopting the above technical solution, when the baffle 36 and the first sealing strip 37 are disengaged from the through groove 301, the moving plate 35 drives the limiting block 351 to slide on the outer surface of the limiting rod 39, thereby assisting the moving plate 35 to slide, so that the baffle 36 is disengaged from or inserted into the through groove 301. Through the first sealing strip 37, the through groove 301 is sealed after the baffle 36 is inserted into the through groove 301.

[0029] A second sealing strip 42 is fixedly installed inside the processing box 21. A connecting plate 4 is provided above the processing box 21. An activated carbon plate 41 is fixedly installed on the bottom surface of the connecting plate 4. The activated carbon plate 41 slides through the second sealing strip 42. A limiting member 45 is slidably installed above the processing box 21. A positioning groove 401 is opened in the connecting plate 4. The limiting member 45 is slidably installed in the positioning groove 401. An insert block 47 is fixedly installed on one side of the limiting member 45.

A spring 44 is fixedly installed between the slider 46 and the sliding groove 211.

[0030] By adopting the above technical solution, two sets of limiting members 45 are provided. By pulling the two sets of limiting members 45, the slider 46 slides on the outer surface of the slide rod 43 and squeezes the spring 44, thereby causing the limiting members 45 to disengage from the positioning groove 401, and thus separating the two sets of limiting members 45, so as to disassemble the connecting plate 4 and the activated carbon plate 41 for easy replacement. After replacement, the activated carbon plate 41 is inserted into the second sealing strip 42 again, and then the limiting members 45 are released, thereby causing the spring 44 to reset, and then the limiting members 45 to reset and slide in the positioning groove 401, so that the two limiting members 45 are in contact, thereby pressing and limiting the connecting plate 4 and the activated carbon plate 41, preventing untreated waste gas from being emitted between the second sealing strip 42 and the connecting plate 4, and avoiding air pollution.

[0031] Working principle: First, after the feed pipe is connected to the external pipeline, diphenylphosphine chloride is stored in the storage tank body 1. At this time, while the storage tank body 1 is transporting and storing diphenylphosphine chloride, pressure will be generated inside it. Then, by turning on the motor 32, the threaded rod 33 will rotate, which will cause the threaded plate 34 to drive the moving plate 35 to slide, and drive the baffle 36 and the first sealing strip 37 to disengage from the through groove 301. At the same time, the waste gas is purified by the activated carbon plate 41, so that the waste gas can be discharged.

[0032] Then, after the discharge pipe is connected to the external pipe, diphenylphosphine chloride is discharged from the storage tank body 1, creating a negative pressure inside the storage tank body 1. At the same time, the motor 32 is turned on again, causing the threaded rod 33 to rotate, which in turn causes the threaded plate 34 to slide the moving plate 35, and causes the baffle 36 and the first sealing strip 37 to disengage from the through groove 301, allowing air to enter the processing box 21 from the discharge pipe 23 and be transported to the storage tank body 1. The air passes through the filter screen 24 to filter the dust and impurities in the air.

[0033] By pulling the two sets of limiting members 45, the slider 46 slides on the outer surface of the slide rod 43 and compresses the spring 44, thereby causing the limiting members 45 to disengage from the positioning groove 401, and thus separating the two sets of limiting members 45, so that the connecting plate 4 and the activated carbon plate 41 can be disassembled and replaced. After replacement, the activated carbon plate 41 is inserted into the second sealing strip 42 again, and then the limiting members 45 are released, thereby causing the spring 44 to reset, and then the limiting members 45 to reset and slide in the positioning groove 401, so that the two limiting members 45 fit together, thereby pressing and limiting the connecting plate 4 and the activated carbon plate 41, preventing untreated waste gas from being emitted between the second sealing strip 42 and the connecting plate 4, and preventing air pollution.
