Description

Technical Field

[0001] This utility model relates to the field of sodium methoxide synthesis technology, and more specifically, to a steam conveying device for sodium methoxide synthesis. Background Technology

[0002] Sodium methoxide synthesis refers to the process in which metallic sodium reacts with methanol under certain conditions to produce sodium methoxide and hydrogen gas. This process is usually carried out in an anhydrous environment, and common methods include batch and continuous methods. By controlling factors such as reaction temperature, pressure, and the ratio of raw materials, the reaction is promoted to proceed smoothly, thereby obtaining sodium methoxide, an important chemical raw material. It has wide applications in fields such as organic synthesis, for example, as a catalyst or intermediate in the synthesis of organic compounds such as pesticides, pharmaceuticals, and dyes.

[0003] A search revealed an existing patent (publication number: CN219530567U) that discloses a steam conveying device for sodium methoxide synthesis. The device includes a conveying pipe, with a first shut-off valve connected to and communicating with a methanol storage tank installed on the outer surface of one end of the conveying pipe. A straight cylinder is installed at the end of the conveying pipe near the first shut-off valve, with the end of the straight cylinder facing the conveying pipe open. A connecting pipe is installed at the end of the straight cylinder away from the conveying pipe, and a third shut-off valve is installed at the end of the connecting pipe away from the straight cylinder. The end of the third shut-off valve away from the connecting pipe is connected to the air outlet of an air pump. A second shut-off valve is installed on the outer surface of the connecting pipe. An inflated rubber airbag is slidably installed inside the straight cylinder. An elastic rope is fixedly connected to the spherical surface of the rubber airbag, and the end of the elastic rope away from the rubber airbag is fixedly connected to the inner wall of the straight cylinder via a connector. This invention has the following advantages: it allows for the discharge of residual methanol vapor from the conveying pipe, facilitating the replacement and maintenance of the conveying pipe.

[0004] During the use of the above-mentioned device, the airbag is prone to rupture due to frequent friction between the airbag and the inner wall, which in turn affects the sealing performance and ultimately prevents the methanol vapor inside from being completely discharged, affecting subsequent use. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention utilizes the increased air pressure within the straight cylinder to propel the cylindrical gas bladder within the gas bladder section towards the gas delivery pipe. During this movement, the cylindrical gas bladder maintains close contact with the inner wall of the gas delivery pipe, and under the pressure, it pushes the residual methanol vapor within the pipe forward and discharges it into the sodium methoxide synthesis tower. Simultaneously, the increased area grooves on the cylindrical gas bladder effectively increase the contact area with the inner wall of the gas delivery pipe, enhancing sealing and reducing vapor leakage. At the same time, the pressure balancing pipe balances the internal air pressure of the gas bladder section, preventing it from rupturing due to excessive pressure. Even if one of the multiple gas bladder sections ruptures accidentally, the remaining unruptured sections maintain good sealing, continuing to perform their sealing and pushing functions, ensuring the effective discharge of methanol vapor from the gas delivery pipe.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0025] A preferred embodiment of the steam conveying device for sodium methoxide synthesis provided by this utility model is, for example... Figures 1 to 5 As shown: It includes: a gas transmission pipe 1; a first connector assembly 2 assembled on the gas transmission pipe 1, the first connector assembly 2 being used to transport sodium methoxide; a vapor removal assembly 3 assembled on one side of the gas transmission pipe 1, the vapor removal assembly 3 being used to extrude sodium methoxide; a second connector assembly 4 assembled at one end of the vapor removal assembly 3, the second connector assembly 4 being used to exhaust air; and an air supply assembly 5 assembled at one end of the second connector assembly 4, the air supply assembly 5 being used to provide airflow.

[0026] In this embodiment, the first connector assembly 2 includes: a branch pipe 201 fixedly installed on the outer surface of the gas transmission pipe 1, a shut-off valve 202 fixedly installed at the bottom of the branch pipe 201, and a connecting pipe 203 fixedly installed at the bottom of the shut-off valve 202.

[0027] In this embodiment, the steam removal assembly 3 includes: a straight cylinder 301 fixedly installed on one side of the gas supply pipe 1, a fixing member 302 fixedly installed inside the straight cylinder 301, a connecting rod 303 fixedly installed on the inner side of the fixing member 302, an elastic rope 304 fixedly installed on the outer surface of the connecting rod 303, and an airbag part 305 assembled at one end of the elastic rope 304.

[0028] In this embodiment, the airbag part 305 includes: a rope rod 306 fixedly installed at one end of the elastic rope 304, a cylindrical airbag 307 fixedly installed on one side of the rope rod 306, an area enlargement groove 308 opened on the cylindrical airbag 307, and an air pressure balance tube 309 fixedly installed at one end of the cylindrical airbag 307.

[0029] In this embodiment, three sets of airbag sections 305 are provided, and the three sets of airbag sections 305 are equidistantly connected to each other.

[0030] Example 2

[0031] Based on Example 1, a preferred embodiment of the steam conveying device for sodium methoxide synthesis provided by this invention is as follows: Figures 1 to 5 As shown: The second connector assembly 4 includes: a connecting pipe 401 fixedly installed on one side of the straight cylinder 301, a branch pipe 402 fixedly installed at the bottom of the connecting pipe 401, and a shut-off valve 403 fixedly installed on the branch pipe 402.

[0032] In this embodiment, the air supply assembly 5 includes: a shut-off valve 501 fixedly installed on one side of the connecting pipe 401, a connecting pipe 502 fixedly installed at one end of the shut-off valve 501, and an air pump 503 fixedly installed at one end of the connecting pipe 502.

[0033] In this embodiment, an anti-corrosion film is installed on the outer surface of the elastic rope 304 to prevent the elastic rope 304 from being corroded.

[0034] Based on Embodiments 1 and 2, the working process of the steam conveying device for sodium methoxide synthesis provided by this utility model is as follows: After methanol vapor is conveyed through the gas supply pipe 1, when residual steam needs to be discharged, firstly, the shut-off valve 202 in the first connector assembly 2 is closed to disconnect the methanol storage tank from the gas supply pipe 1. Then, the air pump 503 in the air supply assembly 5 is started. The air force generated by the air pump 503 passes sequentially through the connecting pipe 3 502, the shut-off valve 3 501, the connecting pipe 2 401, the branch pipe 2 402, and the shut-off valve 2 403, and enters the straight cylinder 301 of the steam discharge assembly 3. The air pressure inside the straight cylinder 301 increases, pushing the cylindrical airbag 307 in the airbag part 305 towards the gas supply pipe 1. During the movement, the cylindrical airbag 307 is tightly attached to the inner wall of the gas supply pipe 1, and under the push of the air pressure, it propels the residual methanol vapor in the gas supply pipe 1 forward and discharges it into the sodium methoxide synthesis tower. At this time, the increased area groove 308 on the cylindrical airbag 307 effectively increases the contact area with the inner wall of the gas transmission pipe 1, enhances sealing, and reduces vapor leakage. Simultaneously, the pressure balancing pipe 309 balances the internal pressure of the airbag section 305, preventing the airbag from rupturing due to excessive pressure. Even if one of the multiple airbag sections 305 ruptures accidentally, the other unruptured airbag sections 305 maintain good sealing and continue to perform their sealing and pushing functions, ensuring that methanol vapor in the gas transmission pipe 1 can be effectively discharged. After the methanol vapor is exhausted, the shut-off valve 301 and shut-off valve 203 are closed, and the exhaust function of the second connector assembly 4 is activated. The remaining gas is discharged through the pressure balancing pipe 309, and the elastic rope 304 drives the airbag section 305 to reset. Furthermore, the anti-corrosion film on the outer surface of the elastic rope 304 prevents corrosion and extends its service life. The entire device enhances its durability and reliability by setting multiple sets of equidistant interconnected structures in the airbag section 305. This effectively solves the problem that during the use of the aforementioned device, the frequent friction between the airbag and the inner wall can easily lead to airbag rupture, which in turn affects the sealing performance and ultimately prevents the complete discharge of methanol vapor, thus affecting subsequent use.
