Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to a methanol feeding device for methoxypropylamine processing. Background Technology

[0002] Methoxypropylamine is an important organic intermediate widely used in dyes, antioxidants, preservatives, and pesticides. Its synthesis typically involves the addition reaction of methanol and acrylonitrile, followed by hydrogenation to produce the target product. The design and operation of the methanol feed unit are crucial to ensuring the efficiency and safety of this process.

[0003] However, when using the feeding device, sometimes there are situations where the inner wall of the feeding conveying pipe is left with residue that is inconvenient to clean, or the pipe is damaged and needs to be replaced but is inconvenient to replace. This leads to an increase in the manpower required for pipe maintenance, which in turn affects the overall production efficiency. Utility Model Content

[0004] This invention addresses the problem that sometimes when using a feeding device, residue remains on the inner wall of the feeding pipeline, making it inconvenient to clean, or that the pipeline is damaged and needs to be replaced, but it is inconvenient to replace. Therefore, it provides a methanol feeding device for methoxypropylamine processing.

[0005] This utility model is achieved by the following technical solution: a methanol feeding device for methoxypropylamine processing, comprising a connecting mechanism, a storage mechanism and a conveying mechanism, wherein the connecting mechanism is located at the lower end of the storage mechanism and the conveying mechanism is located at the left end of the connecting mechanism;

[0006] The connecting mechanism includes a connecting protrusion, with mounting brackets fixedly connected to both sides of the connecting protrusion. A rotating shaft is rotatably connected to the inner wall of the mounting bracket. A connecting rod is fixedly connected to the surface of the rotating shaft. A threaded sleeve is threadedly connected to the surface of the connecting rod. A limit frame is engaged with the surface of the threaded sleeve. A connecting concave sleeve is fixedly connected to the surface of the limit frame. A sealing gasket is engaged with the inner wall of the connecting concave sleeve.

[0007] The above technical solution uses the rotation of the connecting rod and the threaded sleeve to control the connection and disconnection of the connecting convex sleeve and the connecting concave sleeve, which realizes the purpose of convenient disassembly when the conveying pipe needs maintenance, thus improving the overall practicality of the device.

[0008] As a further improvement to the above solution, the right end of the connecting protrusion is engaged with the left end of the sealing gasket, and the right end of the connecting protrusion is engaged with the inner wall of the connecting concave sleeve.

[0009] As a further improvement to the above solution, the storage mechanism includes a storage tank, a support frame is fixedly connected to the left end of the storage tank, a connecting ring is fixedly connected to the surface of the storage tank, a support leg is fixedly connected to the lower end of the connecting ring, a feed pipe is fixedly connected to the upper end of the storage tank, a vacuum pump is fixedly connected to the lower end of the storage tank, and a connecting pipe is fixedly connected to the left end of the vacuum pump.

[0010] The above technical solution, which uses a vacuum pump to drive the methanol inside the storage tank for output, achieves the goal of conveniently putting methanol into the next processing step, making the device more convenient to use.

[0011] As a further improvement to the above solution, the connecting ring is located at the lower end of the support frame, and the support legs are symmetrically distributed at the midpoint of the storage tank, with a total of four support legs.

[0012] As a further improvement to the above solution, the material conveying mechanism includes a conveying pipe, and a connector is fixedly connected to the left end of the conveying pipe.

[0013] As a further improvement to the above solution, the surface of the conveying pipe is engaged with the inner wall of the support frame.

[0014] As a further improvement to the above solution, the left end of the connecting protrusion is fixedly connected to the right end of the conveying pipe, and the right end of the connecting concave sleeve is fixedly connected to the left end of the connecting pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This utility model features a connecting mechanism: when cleaning or maintenance is required inside the conveying pipe, the threaded sleeves at both ends are rotated, causing them to move to the right under the action of the connecting rod thread, thus disengaging them from the slot of the limiting frame. Simultaneously, rotating the threaded sleeves drives the connecting rod to rotate around the pivot axis, thereby releasing the limiting frame from the connecting rod. After the limiting is released, the connecting protrusions and concave sleeves at both ends can be pulled apart, separating the conveying pipe from the connecting pipe for subsequent maintenance. This design, using the rotation of the connecting rod and threaded sleeves to control the connection and disconnection of the connecting protrusions and concave sleeves, allows for convenient disassembly of the conveying pipe when maintenance is needed, improving the overall practicality of the device.

[0017] This invention features a storage mechanism: methanol is fed into a storage tank through the feed pipe at the top of the device, then a vacuum pump is activated. Under the action of the vacuum pump, the methanol inside the storage tank is output to the connecting pipe, and finally, the methanol is sent to the subsequent methoxypropylamine processing via the conveying pipe. The design of using a vacuum pump to drive the output of methanol from the storage tank achieves the purpose of conveniently inputting methanol into the next processing step, making the device more convenient to use.

[0026] Example:

[0027] Please combine Figure 1-5 The methanol feeding device for methoxypropylamine processing in this embodiment includes a connecting mechanism 1, a storage mechanism 2, and a conveying mechanism 3. The connecting mechanism 1 is located at the lower end of the storage mechanism 2, and the conveying mechanism 3 is located at the left end of the connecting mechanism 1.

[0028] The connecting mechanism 1 includes a connecting sleeve 101. Mounting brackets 102 are fixedly connected to both sides of the connecting sleeve 101. A rotating shaft 103 is rotatably connected to the inner wall of the mounting bracket 102. A connecting rod 104 is fixedly connected to the surface of the rotating shaft 103. A threaded sleeve 105 is threadedly connected to the surface of the connecting rod 104. A limiting bracket 106 is snapped onto the surface of the threaded sleeve 105. A connecting recess 107 is fixedly connected to the surface of the limiting bracket 106. A sealing gasket 108 is snapped onto the inner wall of the connecting recess 107. The design of using the rotation of the connecting rod 104 and the threaded sleeve 105 to control the connection and disconnection of the connecting sleeve 101 and the connecting recess 107 realizes the purpose of convenient disassembly when the conveying pipe 301 needs maintenance, thus improving the overall practicality of the device.

[0029] The right end of the connecting convex sleeve 101 is engaged with the left end of the sealing gasket 108, and the right end of the connecting convex sleeve 101 is engaged with the inner wall of the connecting concave sleeve 107.

[0030] The storage mechanism 2 includes a storage tank 201. A support frame 202 is fixedly connected to the left end of the storage tank 201. A connecting ring 203 is fixedly connected to the surface of the storage tank 201. A support leg 204 is fixedly connected to the lower end of the connecting ring 203. A feed pipe 205 is fixedly connected to the upper end of the storage tank 201. A vacuum pump 206 is fixedly connected to the lower end of the storage tank 201. A connecting pipe 207 is fixedly connected to the left end of the vacuum pump 206. The design of using the vacuum pump 206 to drive the methanol inside the storage tank 201 for output achieves the purpose of conveniently putting methanol into the next processing step, making the use of the device more convenient.

[0031] The connecting ring 203 is located at the lower end of the support frame 202, and the support legs 204 are symmetrically distributed at the midpoint of the storage tank 201. There are four support legs 204.

[0032] The material conveying mechanism 3 includes a conveying pipe 301, and a connector 302 is fixedly connected to the left end of the conveying pipe 301.

[0033] The surface of the delivery pipe 301 is engaged with the inner wall of the support frame 202.

[0034] The left end of the connecting convex sleeve 101 is fixedly connected to the right end of the conveying pipe 301, and the right end of the connecting concave sleeve 107 is fixedly connected to the left end of the connecting pipe 207.

[0035] The implementation principle of the methanol feeding device for methoxypropylamine processing in this embodiment is as follows: When using the device, methanol is first fed into the storage tank 201 through the feed pipe 205 at the upper end of the device for storage. Then, the vacuum pump 206 is started. Under the action of the vacuum pump 206, the methanol inside the storage tank 201 is driven out to the connecting pipe 207. Finally, the methanol is sent to the subsequent methoxypropylamine processing through the conveying pipe 301. The design of using the vacuum pump 206 to drive the methanol inside the storage tank 201 for output achieves the purpose of conveniently feeding methanol into the next processing step, making the device more convenient to use. When the inside of the conveying pipe 301 needs to be cleaned or its body needs to be maintained, the threaded sleeves 105 at both ends are rotated to make it connect... The connecting rod 104 moves to the right under the action of the thread, thereby disengaging it from the slot of the limiting frame 106. Then, the threaded sleeve 105 is rotated, which simultaneously drives the connecting rod 104 to rotate around the rotating shaft 103 as the midpoint. This drives the connecting rod 104 and the threaded sleeve 105 to release the limiting frame 106. After the limiting is released, the connecting protrusions 101 and connecting concave sleeves 107 at both ends can be pulled to separate, thereby separating the conveying pipe 301 from the connecting pipe 207, so as to facilitate subsequent maintenance of the conveying pipe 301. The design of using the rotation of the connecting rod 104 and the threaded sleeve 105 to control the connection and disconnection of the connecting protrusions 101 and connecting concave sleeves 107 achieves the purpose of convenient disassembly when the conveying pipe 301 needs maintenance, improving the overall practicality of the device.
