They are widely found in nature and in artificially synthesized materials and have important chemical, biological, and industrial applications. For example, ammonium polyphosphate is an important chemical product, usually a white powder with good thermal stability and water solubility. Ammonium polyphosphate has a wide range of applications in many fields. During production and use, it is necessary to transport ammonium polyphosphate from one process to another, which places high demands on the safety, stability, and efficiency of the transport system.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Example 1

[0030] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the first embodiment of the present invention. This embodiment provides an explosion-proof vacuum conveying system for phosphorus-containing compounds, including a storage machine 1. A locking mechanism 2 is provided on one side of the storage machine 1, and a locking mechanism 3 is provided on the other side of the storage machine 1.

[0031] The locking mechanism 2 includes a straight pipe 203 fixedly installed at the bottom of the storage machine 1. A curved pipe 201 is provided on one side of the straight pipe 203. A sealing gasket 206 is provided on the opposite side of the straight pipe 203 and the curved pipe 201. An upper arc-shaped locking plate 204 and a lower arc-shaped locking plate 202 are movably installed on the outer side of the curved pipe 201 and the straight pipe 203.

[0032] Specifically, the sealing gasket 206 is placed on the opposite side of the straight pipe 203 and the curved pipe 201, the curved pipe 201 is completely fitted to one side of the straight pipe 203, the upper arc-shaped clamping plate 204 and the lower arc-shaped clamping plate 202 are clamped at the interface between the straight pipe 203 and the curved pipe 201, and the straight pipe 203 and the curved pipe 201 are quickly connected. The sealing gasket 206 improves the sealing performance of the straight pipe 203 and the curved pipe 201 when conveying materials.

[0033] A limiting rod 205 is installed on the outer surface of the upper arc-shaped clamping plate 204, and a rotating shaft 207 is fixedly provided on the outer surface of the lower arc-shaped clamping plate 202. A clamping rod 208 is movably provided inside the rotating shaft 207.

[0034] Specifically, after the upper arc-shaped clamping plate 204 is rotated to fully engage with the lower arc-shaped clamping plate 202 on one side, the clamping rod 208 is pulled to move upward inside the rotating shaft 207, and the clamping rod 208 is clamped on the limiting rod 205, thereby fixing the lower arc-shaped clamping plate 202 and the upper arc-shaped clamping plate 204, wherein the shaft of the rotating shaft 207 can rotate.

[0035] Limiting rings 209 are symmetrically installed on the outer surface of the clamping rod 208. A first spring 210 is provided on one side of the two limiting rings 209 facing each other. A nut 211 is threadedly installed on the outer surface of the clamping rod 208.

[0036] Specifically, after the locking rod 208 is locked onto the limiting rod 205, under the action of the first spring 210, the first spring 210 pushes the limiting ring 209 at its bottom outward, thereby stably locking the locking rod 208 onto the limiting rod 205. By rotating the nut 211 at different positions on the locking rod 208, the thrust applied by the first spring 210 to the lower limiting ring 209 can be increased.

[0037] The upper arc-shaped clamping plate 204 is hinged to one side of the lower arc-shaped clamping plate 202, the clamping rod 208 is movably inserted into the inside of the rotating shaft 207, the two limiting rings 209 are both located at the bottom of the rotating shaft 207, the first spring 210 is located outside the clamping rod 208, and the nut 211 is located at the bottom of the first spring 210.

[0038] Furthermore, after placing the curved pipe 201 close to one side of the straight pipe 203 and adjusting the outlet orientation of the curved pipe 201, the upper arc-shaped clamping plate 204 and the limiting rod 205 are both clamped at the interface between the curved pipe 201 and the straight pipe 203. After the clamping is completed, the clamping rod 208 is pulled upward, and then the clamping rod 208 is clamped on the limiting rod 205. Under the action of the first spring 210, a reverse force is applied to the tail of the clamping rod 208, and the clamping rod 208 is stably clamped on the limiting rod 205, thus completing the connection between the curved pipe 201 and the straight pipe 203.

[0039] Example 2

[0040] Reference Figure 5 and Figure 6 This is the second embodiment of the present invention, which is based on the previous embodiment and includes a snap-fit ​​mechanism 3 that facilitates quick and easy disassembly of the air filter 303.

[0041] The snap-fit ​​mechanism 3 includes an L-shaped pipe 301 fixedly installed at the bottom of the storage machine 1. A fixing ring 302 is fixedly provided on the outer surface of the L-shaped pipe 301, and an air filter 303 is installed on the top of the fixing ring 302.

[0042] Specifically, the air filter 303 is movably installed on the fixing ring 302. Since the air filter 303 filters the air for a long time, it is convenient to install and replace the air filter 303.

[0043] A male locking block 305 is movably installed inside the fixing ring 302. A second spring 307 and a push-pull rod 306 are symmetrically arranged on one side of the male locking block 305. A push-pull plate 308 is fixedly installed on one side of the push-pull rod 306. A female locking block 304 is symmetrically installed at the bottom of the air filter 303.

[0044] Specifically, after the female locking block 304 is fully inserted into the inside of the fixing ring 302, the male locking block 305 is inserted into the female locking block 304. At this time, the air filter 303 is connected to the L-shaped pipe 301. Under the action of the two second springs 307, the male locking block 305 is fully pushed into the groove of the female locking block 304, restricting the female locking block 304 inside the fixing ring 302, thereby installing the air filter 303 on the top of the fixing ring 302.

[0045] The second spring 307 is located outside the push-pull rod 306. The female locking block 304 has a groove on one side that is adapted to the male locking block 305. The female locking block 304 is movably inserted into the inside of the fixing ring 302. Both push-pull rods 306 are slidably connected inside the fixing ring 302.

[0046] Furthermore, when the air filter 303 is installed on top of the fixing ring 302, the air filter 303 drives the female locking block 304 to insert into the interior of the fixing ring 302. At this time, under the action of the two second springs 307, the male locking block 305 is fully pushed into the groove of the female locking block 304, restricting the female locking block 304 inside the fixing ring 302 and fixing the air filter 303 on top of the fixing ring 302. When it is necessary to remove the air filter 303, manually pull the push-pull plate 308 to move outward. The push-pull plate 308 drives the push-pull rod 306 to move outward in the fixing ring 302. The two push-pull rods 306 drive the male locking block 305 to be removed from the groove of the female locking block 304. The air filter 303 can then be manually taken out from the top of the fixing ring 302.

[0047] Working Principle: The ammonium polyphosphate explosion-proof vacuum conveying system includes a blower capable of generating negative pressure, creating a vacuum inside the conveying pipeline. The storage container 1 is an existing structure. Ammonium polyphosphate raw material is placed in storage container 1. By controlling the blower's operation, the raw material is conveyed through the vacuum-created pipeline, and the material is separated into different vacuum containers. A separation switch is installed in the middle of the pipeline to further separate the material into different vacuum containers, thus forming a complete ammonium polyphosphate explosion-proof vacuum conveying system. All of the above are existing structures and are compatible with current... As disclosed in some cases, when connecting pipes, the sealing gasket 206 is placed on the opposite side of the straight pipe 203 and the curved pipe 201, and the curved pipe 201 is completely fitted against one side of the straight pipe 203. The upper arc-shaped clamping plate 204 and the lower arc-shaped clamping plate 202 are clamped at the interface between the straight pipe 203 and the curved pipe 201. The clamping rod 208 is pulled upward inside the rotating shaft 207. After the clamping rod 208 is clamped on the limiting rod 205, under the action of the first spring 210, the bottom of the first spring 210 is... The limiting ring 209 is pushed outward, thereby stably engaging the locking rod 208 onto the limiting rod 205. By rotating the nut 211 to different positions on the locking rod 208, the thrust exerted by the first spring 210 on the lower limiting ring 209 can be increased. After fixing, the air filter 303 needs to be installed to provide air supply for the movement of the storage machine 1. At this time, when the air filter 303 is installed on the top of the fixing ring 302, the air filter 303 drives the female locking block 304 to insert into the interior of the fixing ring 302. At this time, the two second springs 307... Under the action, the male locking block 305 is fully pushed into the groove of the female locking block 304, restricting the female locking block 304 inside the fixing ring 302, and fixing the air filter 303 to the top of the fixing ring 302. When the air filter 303 needs to be removed, manually pull the push-pull plate 308 to move outward. The push-pull plate 308 drives the push-pull rod 306 to move outward in the fixing ring 302. The two push-pull rods 306 drive the male locking block 305 to be removed from the groove of the female locking block 304. The air filter 303 can then be manually taken out from the top of the fixing ring 302.
