DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Example

[0025] See also Figures 1 to 5 , is an embodiment of the present invention, which provides a technical solution: a device for collecting and discharging nylon sublimation monomers, comprising:

[0026] A duckbill suction hood 1, a strip suction port is arranged at the inlet of the duckbill suction hood 1, and the thickness of the inlet of the duckbill suction hood 1 is half of the thickness of the outlet of the duckbill suction hood 1. This thinning design at the inlet can increase the suction force at the inlet, and solves the problem that the suction force at the inlet of the traditional suction device is not strong and easy to be blocked. Such a design not only improves the suction efficiency, but also reduces the on-site environmental pollution caused by leakage due to insufficient suction force, so that the on-site environment is clean, the cleaning frequency is reduced, the nearby equipment is protected, and the fire risk is reduced. A reinforcing rib 2 is also fixed at the inner center of the duckbill suction hood 1. The design of the reinforcing rib 2 can support the inner side of the duckbill suction hood 1 during the subsequent suction process. Therefore, under the support of the reinforcing rib 2, the lateral size of the duckbill suction hood 1 can be increased as much as possible, thereby increasing the lateral working space of the duckbill suction hood 1, so that it can meet more and larger spinning unit distances;

[0027] The curved pipe 3 installed at the outlet of the duckbill suction hood 1 has a cleaning port 31, which can facilitate subsequent operators to clean the inside of the curved pipe 3 through the cleaning port 31, solving the problem that the traditional suction device is not easy to clean and maintain, and the surface of the curved pipe 3 is provided with a detachable blocking structure, and the cleaning port 31 can be blocked by the arc-shaped sealing plate 32 when cleaning is not required, without affecting the suction wind force;

[0028] And a suction pipe 5 is installed at the end of the curved pipe 3, and the end of the suction pipe 5 is connected to an external suction pump.

[0029] Among them, brackets 4 are fixed on both sides of the inlet of the duckbill suction hood 1, and reserved mounting holes are provided on the brackets 4 for subsequent installation and fixation of the duckbill suction hood 1. Two bolt holes are provided on both sides of the inlet of the duckbill suction hood 1, and the bracket 4 is fixedly connected to the duckbill suction hood 1 by two bolts.

[0030] The detachable plugging structure includes an arc-shaped sealing plate 32 installed on the outer surface of the curved pipe 3 and covering the cleaning port 31, and a U-shaped sealing ring 33 is glued and fixed to the inner surface of the curved sealing plate 32. The U-shaped sealing ring 33 is made of rubber material and is embedded in the cleaning port 31. The detachable plugging structure also includes two cylindrical movable seats 39 movably installed on the outer surface of the curved pipe 3, and the surfaces of the two cylindrical movable seats 39 are welded and fixed with arc-shaped pressure plates 34, and the arc-shaped pressure plates 34 are pressed on the surface of the arc-shaped sealing plate 32 to achieve the compression and limitation of the arc-shaped sealing plate 32. The outer surface of the curved pipe 3 is fixed with a cylindrical base rod 3 on both sides of the cleaning port 31. 10. An inner groove 311 is opened in the cylindrical movable seat 39, and an inner base plate 312 and a spring 313 are installed in the inner groove 311. The end of the cylindrical base rod 310 passes through the inner groove 311 and is fixed to the inner base plate 312. Under the pushing action of the spring 313, the arc pressure plate 34 can be stably pressed on the surface of the arc sealing plate 32 during daily use to ensure the clamping stability of the arc sealing plate 32. Due to the cylindrical structural characteristics of the cylindrical base rod 310, the cylindrical movable seat 39 can not only be displaced along the axial direction of the cylindrical base rod 310, but also can be rotated around the cylindrical base rod 310, so as to realize the smooth rotation of the cylindrical movable seat 39 after side pulling.

[0031] The detachable sealing structure further includes a limit block 37 welded to the inner surface of the arc pressure plate 34 and two limit slots 38 provided on the outer surface of the arc sealing plate 32. The limit block 37 is embedded in the limit slot 38, so that the arc pressure plate 34 can be stably pressed on the surface of the arc sealing plate 32 during daily use, and will not be easily rotated and removed from the surface of the arc sealing plate 32. When it is necessary to open the cleaning port 31 to clean and maintain the inside of the elbow 3 in the later stage, it is only necessary to first remove the cylindrical movable The seat 39 is pulled outward, so that the spring 313 is gradually compressed, and the arc pressure plate 34 moves with the cylindrical movable seat 39 until the limit block 37 moves out of the limit slot 38. At this time, the arc pressure plate 34 and the cylindrical movable seat 39 can be rotated so that the arc pressure plate 34 is rotated and moved away from the outer side of the arc sealing plate 32, and no longer causes obstruction to the arc sealing plate 32. At this time, the arc sealing plate 32 can be removed, so that the operator can clean and maintain the inside of the bent pipe 3 through the cleaning port 31.

[0032] Among them, the detachable sealing structure also includes a U-shaped sealing ring 35 glued and fixed to the inner surface of the arc-shaped sealing plate 32. The U-shaped sealing ring 35 is made of rubber material, and the surface of the curved pipe 3 is provided with a U-shaped sealing groove 36 corresponding to the U-shaped sealing ring 35. The U-shaped sealing groove 36 surrounds the cleaning port 31, so that when the subsequent arc-shaped sealing plate 32 is pressed on the outer surface of the curved pipe 3, the U-shaped sealing ring 35 will also be squeezed into the U-shaped sealing groove 36 to form a sealing structure, further ensuring the sealing of the arc-shaped sealing plate 32 to the cleaning port 31, and because the entire device is a suction device, the arc-shaped sealing plate 32 will be sucked tighter and tighter during daily suction and collection of nylon sublimation monomers to ensure sealing.

[0033] Although embodiments of the present invention have been shown and described (see the above detailed description for details), it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
