Description

Technical Field

[0001] The utility model relates to the technical field of methyl iodide storage, in particular to a leakage-proof methyl iodide storage tank. Background Art

[0002] Methyl iodide, also known as methyl iodide, is an active alkylating agent. It is a colorless transparent liquid with a special smell. Its structural formula is CH3I, its relative molecular mass is 141.95, its relative density is 2.279, 2.3346 (0 degrees Celsius), 2.2510 (30 degrees Celsius), its melting point is -66.4 degrees Celsius, its boiling point is 42.5 degrees Celsius, its refractive index is 1.5380, and its decomposition temperature is 270 degrees Celsius. It is soluble in water, acetone, benzene, etc., and is miscible with ethanol and ether. It decomposes when exposed to light, releasing iodine and turning into brown. It is hydrolyzed in an alkaline solution to produce methanol and iodine, which are toxic and corrosive.

[0003] However, when the iodomethane storage tank is stored, the external temperature is not constant. When the temperature rises, the pressure inside the iodomethane storage tank increases. In addition, since the inside of the tank is sealed, if it is not handled in time, the tank may burst, causing iodomethane leakage. In addition, most of the existing iodomethane storage tanks are not equipped with fixing devices. During storage and transportation, collisions may occur, causing the tank to rupture. There is also a certain risk of leakage. Therefore, there are certain limitations.

[0004] For this reason, we urgently need to provide a leak-proof methyl iodide storage tank. Utility Model Content

[0005] The utility model aims to provide a leakage-proof methyl iodide storage tank to solve the problem that most of the existing methyl iodide storage tanks proposed in the above background technology are not provided with fixing devices, and collisions may occur during storage and transportation, thereby causing the tank body to rupture and posing a certain risk of leakage.

[0006] To achieve the above objectives, the utility model provides the following technical solutions: a leak-proof methyl iodide storage tank, comprising a fixing frame and a storage tank, wherein the storage tank is placed inside the fixing frame, a fixing device is arranged on the fixing frame, and a pressure relief device is arranged on the top of the storage tank.

[0007] The fixing device comprises a fixing unit and an adjusting unit.

[0008] The fixing unit includes a connecting frame, an arc-shaped plate, a movable plate, a fixed plate, and fixing bolts. The connecting frame is fixedly connected to the lower front side of the fixing frame, the arc-shaped plate is fixedly connected to the front end of the connecting frame, the movable plate is hinged on the arc-shaped plate, the two fixing plates are respectively fixedly connected to the left sides of the arc-shaped plate and the movable plate, and the two fixing bolts are respectively threadedly connected to the fixing plates.

[0009] A further improvement is that threaded holes are respectively opened on the upper and lower sides of the fixed plate, and the fixing bolts are threadedly connected to the inside of the threaded holes. The storage tank is placed inside the arc plate, and then the movable plate is rotated to make the fixed plate on its left side fit with the fixed plate on the left side of the arc plate, and the fixing bolts are screwed in to connect the arc plate and the movable plate, so as to fix the storage tank and avoid collision, which may cause the risk of the tank body rupture and leakage.

[0010] A further improvement is that the adjustment unit includes a threaded rod, a bearing, and an arc-shaped fixing plate, the threaded rod is installed on the front side of the movable plate, the bearing is installed on the rear end of the threaded rod, and the arc-shaped fixing plate is fixedly connected to the rear end of the bearing.

[0011] A further improvement is that an adjustment threaded hole is opened in the center of the front side of the movable plate, and the threaded rod is rotatably connected to the inside of the adjustment threaded hole. When facing a storage tank with a smaller diameter, the threaded rod is twisted to move it toward the inside of the adjustment threaded hole, thereby pushing the arc-shaped fixed plate to move backward, so that the storage tank with a smaller diameter is tightly attached to the arc-shaped plate and fixed, thereby improving the adaptability of the device.

[0012] A further improvement is that the pressure relief device includes a pressure relief unit and a protection unit.

[0013] The pressure relief unit includes a pressure relief pipe, an electric sealing valve, a strong spring, and a sealing block. The pressure relief pipe is fixedly connected to the right top of the storage tank, the electric sealing valve is installed on the left side of the pressure relief pipe, the strong spring is fixedly connected to the right wall of the pressure relief pipe, and the sealing block is fixedly connected to the left end of the strong spring.

[0014] A further improvement is that a pressure relief hole is opened on the right side of the pressure relief pipe, a pressure gauge is installed on the top of the storage tank, and the electric sealing valve is electrically connected to the pressure gauge. When the pressure gauge detects that the pressure inside the storage tank has increased, it promptly reminds people through the central controller to deal with it. If it is not dealt with in time, the internal pressure of the storage tank continues to increase to the warning value, then the electric sealing valve is opened, and the air pressure pushes the sealing block to move to the right along the inner wall of the pressure relief pipe and squeezes the strong spring until the sealing block moves to the right side of the pressure relief hole, and the high-pressure airflow inside the storage tank is discharged through the pressure relief hole, which effectively prevents the storage tank from bursting due to excessive internal pressure and avoids large-scale leakage of methyl iodide.

[0015] A further improvement is that the protection unit includes a water tank, a water inlet pipe, and a sealing cover. The water tank is fixedly connected to the right top of the storage tank, the water inlet pipe is fixedly connected to the top of the water tank, and the sealing cover is threadedly connected to the top of the water inlet pipe. A small amount of leaked methyl iodide is discharged into the interior of the water tank through the pressure relief hole, and is dissolved in the water inside the water tank to avoid being inhaled into the human body and affecting personal safety.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The leak-proof methyl iodide storage tank is placed inside the arc plate, and then the movable plate is rotated to fit the fixed plate on the left side of the arc plate with the fixed plate on the left side of the arc plate, and the fixing bolts are screwed in to connect the arc plate and the movable plate, thereby fixing the storage tank to avoid collision and the risk of tank rupture and leakage.

[0018] 2. When facing a storage tank with a smaller diameter, the leak-proof methyl iodide storage tank twists the threaded rod to move it toward the inside of the adjusting threaded hole, thereby pushing the arc-shaped fixing plate to move backward, so that the storage tank with a smaller diameter is closely attached to the arc-shaped plate and fixed, thereby improving the adaptability of the device.

[0019] 3. For the leak-proof methyl iodide storage tank, when the pressure inside the storage tank is too high, the air pressure pushes the sealing block to move to the right along the inner wall of the pressure relief pipe and squeezes the strong spring until the sealing block moves to the right side of the pressure relief hole. The high-pressure airflow inside the storage tank is discharged through the pressure relief hole, effectively preventing the storage tank from bursting due to excessive internal pressure and preventing large amounts of methyl iodide from leaking.
