Description

Technical Field

[0001] The utility model relates to the technical field of sodium methoxide storage, in particular to a sodium methoxide safe storage detection device. Background Art

[0002] Sodium methoxide typically appears as white or slightly yellowish crystals or powder. It has a wide range of applications, primarily in the production of sulfonamides. It is also a catalyst in organic synthesis, used in pesticide production and the oil and fat processing industry. It is also used as an alkaline condensation agent and catalyst in organic synthesis. Sodium methoxide is toxic and prolonged exposure or inhalation may pose a health hazard to humans. Therefore, when handling and storing sodium methoxide, strict safety procedures must be followed and necessary protective measures must be taken, such as wearing protective glasses, protective clothing, and gloves, and maintaining good ventilation.

[0003] The storage of sodium methoxide requires special attention to its chemical properties and hazards. In terms of storage, there are mainly solids and liquids. The solid is pure sodium methoxide, and the liquid is methanol solution of sodium methoxide. Sodium methoxide is easily decomposed or deteriorated when exposed to water, light, oxygen, etc., so they are all stored in sealed containers. Since sodium methoxide is a hazardous chemical, according to regulatory regulations, the storage of sodium methoxide needs to be strictly supervised. Sodium methoxide is mainly stored in warehouses through storage tanks. The storage safety needs to be checked during the process of entering and leaving the warehouse. For this reason, we proposed a sodium methoxide safe storage detection device to solve the above problems. Utility Model Content

[0004] The present application provides a sodium methoxide safe storage detection device, which solves the problem of sodium methoxide safety detection before storage.

[0005] The present application provides a sodium methoxide safe storage detection device, comprising a negative pressure chamber located at the entrance of a warehouse, wherein the front and rear ends of the negative pressure chamber are both provided with openings, and the openings are provided with sealing doors. A plurality of air inlet pipes are provided on one side of the negative pressure chamber, and a plurality of air suction hoods are provided on the side of the negative pressure chamber opposite to the air inlet pipe. The plurality of air suction hoods are connected to a negative pressure pipe through a connecting pipe, one end of the negative pressure pipe is connected to a detection barrel, a negative pressure fan is installed on the negative pressure pipe, the negative pressure pipe extends into the detection barrel, and a methanol sensor is provided in the detection barrel.

[0006] Preferably, the methanol sensor is capable of gas phase detection and liquid phase detection of alcohols.

[0007] Preferably, the negative pressure tube is located at one end of the detection barrel and is installed on the heating tube.

[0008] Preferably, the negative pressure chamber is located outside the warehouse entrance.

[0009] Preferably, distribution pipes are provided on both sides of the negative pressure pipe.

[0010] Preferably, a one-way nozzle is provided on the bottom side of the distribution pipe.

[0011] Preferably, a one-way valve is also installed on the negative pressure tube.

[0012] Preferably, an air inlet plate is provided in the air inlet duct.

[0013] Preferably, there are multiple methanol sensors, which are distributed in a ring around the detection barrel.

[0014] Preferably, an exhaust pipe is installed on the detection barrel, and a rainproof cap is installed on the top of the exhaust pipe.

[0015] It can be seen from the above technical solution that the present application provides a sodium methoxide safe storage detection device. When in use, the present application adds a small amount of water to the detection barrel to cover the negative pressure tube, and then the methanol tank to be stored or shipped is first sent to the negative pressure chamber by a cart, and then the sealing door is closed. After standing for 2-3 minutes, the negative pressure fan is started to draw the gas in the negative pressure chamber into the negative pressure tube through the suction hood, and the mixed gas in the negative pressure chamber enters the detection barrel. If the methanol tank leaks or deteriorates and decomposes, the sodium methoxide in the mixed gas or the decomposed methanol will dissolve in the water in the detection barrel, wherein the sodium methoxide reacts with water to generate methanol that dissolves in the water, causing the methanol value in the water to change, thereby detecting whether the sodium methoxide in the detection barrel is stored intact, whether it deteriorates or leaks, wherein the setting of the air inlet pipe can effectively improve the air flow, and the air inlet pipe and the suction hood are in relative positions, which can bring the gas around the methanol tank into the negative pressure tube.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. Through the setting of the negative pressure chamber, the flowing airflow can be used to detect the sodium methoxide storage tanks entering and leaving. Multiple barrels of storage tanks can be placed for testing at one time, with high detection efficiency;

[0018] 2. By setting the negative pressure fan, the air flow rate and flow rate in the negative pressure chamber can be controlled, and the gas around the storage tank can be extracted and tested within a unit time;

[0019] 3. Through the setting of methanol sensor and detection barrel, the extracted gas can be processed and uniformly converted into methanol, and then directly detected by methanol sensor to improve sensitivity.

[0020] To sum up, the present application can detect methanol tanks that are put into storage in batches. By collecting and processing the gas around the methanol tanks, it can detect whether there is methanol and measure whether a leak has occurred. The information is collected quickly and the detection efficiency is high. When a leak occurs, only the batch needs to be checked to find the leak point, thereby completing the inspection work before storage. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] In order to enable people skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0028] See also Figure 1-4, a sodium methoxide safety storage detection device, the present application is used for the inspection work before the methanol tank is put into storage, including a negative pressure chamber 1 located at the warehouse entrance, the negative pressure chamber 1 is built with a movable plate, the negative pressure chamber 1 is located outside the warehouse entrance, that is, outside the doorway of the warehouse, the front and rear ends of the negative pressure chamber 1 are both provided with openings, the opening on one side of the warehouse is the original warehouse door, and the other side opposite is a door set on the movable plate, and a sealing door 12 is provided at the opening, one of which is the original warehouse door, and the other can be set separately. A plurality of air inlet pipes 2 are provided on one side of the negative pressure chamber 1, and the specific air inlet pipe 2 is located on the left or right side of the negative pressure chamber 1. The negative pressure chamber 1 is set outside the warehouse, and there will be debris entering. Therefore, an air inlet plate 3 is provided in the air inlet pipe 2 to effectively block debris and prevent debris such as leaves and garbage from entering through the air inlet pipe 2;

[0029] Multiple suction hoods 5 are arranged on one side of the negative pressure chamber 1 relative to the air inlet pipe 2. The suction hoods 5 are arranged in a trumpet shape, which can form a larger adsorption area, so that the gas can be sucked into the suction hoods 5 more evenly. The multiple suction hoods 5 are connected to the negative pressure pipe 4 through the connecting pipe 13. In this application, the multiple suction hoods 5 are connected by a pipeline to gather all the gases together for processing. One end of the negative pressure pipe 4 is connected to the detection barrel 9, and a negative pressure fan 7 is installed on the negative pressure pipe 4. The mixed gas in the negative pressure pipe 4 is pumped to the detection barrel 9 by the negative pressure fan 7 to be processed into methanol and tested inside. The negative pressure pipe 4 extends into the detection barrel 9. The negative pressure pipe 4 is located at the bottom of the detection barrel 9, so that the mixed gas moves from top to bottom in the detection barrel 9. At the same time, a methanol sensor 10 is provided in the detection barrel 9 to detect the methanol content in the mixed gas.

[0030] In the present invention, the methanol sensor 10 is for gas phase detection and liquid phase detection of alcohols. In addition to directly treating sodium methoxide with water, the present application can also detect the treated gas, detect and record the methanol content in the air, and perform multi-faceted detection on the collected gas;

[0031] To further improve the processing efficiency, the negative pressure tube 4 is located at one end of the detection barrel and is installed on the heating tube 14. The mixed gas is heated before entering the detection barrel 9 so that it can react quickly after contacting with water, thereby increasing the absorption efficiency of the mixed gas and further improving the detection.

[0032] In the present invention, distribution pipes 11 are provided on both sides of the negative pressure pipe 4. The gas in the negative pressure pipe 4 is reacted and absorbed in multiple areas in water through the distribution pipes 11. The reaction efficiency is high and the absorption rate of methanol and sodium methoxide in the mixed gas is high.

[0033] Furthermore, a one-way nozzle 15 is provided on the bottom side of the distribution pipe 11 to prevent the water in the detection tank 9 from flowing into the negative pressure pipe 4;

[0034] Furthermore, a one-way valve 6 is installed on the negative pressure pipe 4, and the one-way valve 6 is located between the negative pressure fan 7 and the detection barrel 9 to prevent the gas in the detection barrel 9 from being backdrawn during the start and stop of the negative pressure fan 7, causing damage to the one-way nozzle 15.

[0035] In some embodiments, in order to improve detection accuracy, there are multiple methanol sensors 10 distributed in a ring around the detection barrel 9, so that the methanol in the detection barrel 9 can be detected at multiple positions.

[0036] In some embodiments, to ensure that the gas can gather in the detection barrel 9, an exhaust pipe 8 is installed on the detection barrel 9. The gas sent into the negative pressure pipe 4 stays and gathers in the detection barrel 9 and then is discharged from the detection barrel 9, thereby improving the water absorption efficiency and detection accuracy. A rain cap is installed on the top of the exhaust pipe 8, and the exhaust pipe 8 can be extended to the outdoors to block rainwater through the rain cap.

[0037] It can be seen from the above technical solution that when in use, the present application adds a small amount of water to the detection barrel 9 to cover the negative pressure tube 4, and then the methanol tank to be stored or shipped is first sent to the negative pressure chamber 1 by a cart, and then the sealing door 12 is closed. After standing for 2-3 minutes, the negative pressure fan 7 is started to draw the gas in the negative pressure chamber into the negative pressure tube 4 through the suction hood 5, and the mixed gas in the negative pressure chamber 1 enters the detection barrel 9. If the methanol tank leaks or deteriorates and decomposes, the sodium methoxide in the mixed gas or the decomposed methanol will dissolve in the water in the detection barrel 9, wherein the sodium methoxide reacts with water to generate methanol that dissolves in water, causing the methanol value in the water to change, thereby detecting whether the sodium methoxide in the detection barrel 9 is stored intact, whether it deteriorates or leaks, and the setting of the air inlet pipe 2 can effectively improve the air flow, and the air inlet pipe 2 and the suction hood 5 are in relative positions, which can bring the gas around the methanol tank into the negative pressure tube 4.
