Abstract
Description
Technical Field
[0001] This utility model belongs to the field of nonwoven fabric production technology, and in particular relates to a waste gas recovery device for nonwoven fabric production. Background Technology
[0002] Nonwoven fabric, also known as non-woven cloth, is made of oriented or random fibers forming a web structure, which is then reinforced by mechanical, thermal bonding, or chemical methods. Meltblown fabric is a type of nonwoven fabric, and the two are related by way of inclusion.
[0003] Meltblown fabric is mainly made of synthetic fibers. During the production process, these polymers need to be heated into a molten state. This process causes the coating agent to volatilize and generate waste gas. The use of a waste gas treatment machine can recover the waste gas and effectively avoid the adverse effects of the waste gas on the surrounding workers. However, if there is a gap at the connection between the connecting pipe and the waste gas treatment machine, the waste gas will leak. To address this, a waste gas recovery device for nonwoven fabric production has been designed. This device adds a reinforcing structure between the connecting pipe and the air inlet of the waste gas treatment machine, which makes the connection between the connecting pipe and the air inlet of the waste gas treatment machine more fixed and tight, thereby avoiding the occurrence of gaps at the connection between the connecting pipe and the waste gas treatment machine. Utility Model Content

[0006] Preferably, the stud is fixedly connected to the six-hole disc by a small nut, and a circular groove is provided on the right side of the ring.
[0007] Preferably, the left side of the convex ring is slidably connected to the inner cavity of the circular groove, and a sealing ring is fitted inside the inner cavity of the circular groove.

The air inlet of the exhaust gas treatment machine 3 and the inner cavity of the connecting pipe 2 are both fitted with an inner rubber ring 9. The stud 7 is fixedly connected to the six-hole disc 4 by a small nut 8. A circular groove 10 is opened on the right side of the circular ring 6. The left side of the convex ring 5 is slidably connected to the inner cavity of the circular groove 10. A sealing ring 11 is fitted in the inner cavity of the circular groove 10. The sealing ring 11 can achieve a sealing effect between the convex ring 5 and the circular ring 6, which can further prevent gaps from forming at the connection between the connecting pipe 2 and the exhaust gas treatment machine 3. A four-hole disc 12 is welded to the surface of both the convex ring 5 and the circular ring 6.
[0027] Example 2:
[0028] Figure 1-6This invention illustrates an embodiment of a waste gas recovery device for nonwoven fabric production, comprising a connecting pipe 2 connected to the left side of a nonwoven fabric production machine 1; a waste gas treatment machine 3 is arranged on the left side of the nonwoven fabric production machine 1; a six-hole disc 4 is welded to the surface of both the air inlet of the waste gas treatment machine 3 and the surface of the connecting pipe 2; a convex ring 5 is fitted onto the surface of the connecting pipe 2; a circular ring 6 is fitted onto the surface of the air inlet of the waste gas treatment machine 3; six studs 7 are welded to the opposite sides of the convex ring 5 and the circular ring 6; the surface of the studs 7 is slidably connected to the inner cavity of the six-hole disc 4; and a small nut 8 is threaded onto the surface of the studs 7. The inner cavity of the air inlet and the connecting pipe 2 is fitted with a rubber liner 9. The surfaces of the convex ring 5 and the circular ring 6 are fitted with rubber gaskets 13. The rubber gaskets 13 make the contact surfaces between the inner cavity of the collar 14 and the convex ring 5 and the circular ring 6 more flexible, and at the same time make the connection between the collar 14 and the convex ring 5 and the circular ring 6 tighter. The collar 14 is slidably connected to the opposite side of the convex ring 5 and the circular ring 6. The rubber gaskets 13 are located in the inner cavity of the collar 14. The inner cavities of the two collars 14 are threadedly connected with bolts 15. The surface of the bolts 15 is threadedly connected with nuts 16.
[0029] Working Principle: In use, the user welds two six-hole discs 4 to the surfaces of the air inlet of the exhaust gas treatment machine 3 and the connecting pipe 2, respectively. Then, the circular ring 6 and the convex ring 5 are respectively fitted onto the surfaces of the air inlet of the exhaust gas treatment machine 3 and the connecting pipe 2. The stud 7 is then slidably connected to the inner cavity of the six-hole discs 4. Next, a small nut 8 is used to thread and fix the stud 7, thereby fixing the convex ring 5 and the circular ring 6 to the connecting pipe 2 and the exhaust gas treatment machine 3, respectively. Finally, the inner rubber ring 9 is slid into the inner cavity of the exhaust gas treatment machine 3. The cavity is opened, and the connecting pipe 2 is slid towards the air inlet of the exhaust gas treatment machine 3. Then, the inner cavity of the connecting pipe 2 is fitted onto the surface of the inner rubber ring 9, thereby achieving a sealing effect between the connecting pipe 2 and the exhaust gas treatment machine 3. Subsequently, the rubber gasket ring 13 and the collar ring 14 are successively fitted onto the surfaces of the convex ring 5 and the circular ring 6, and bolts 15 and nuts 16 are aligned and fixed. This makes the connection between the connecting pipe 2 and the air inlet of the exhaust gas treatment machine 3 more fixed and tight, thereby avoiding gaps at the connection between the connecting pipe 2 and the exhaust gas treatment machine 3.
[0030] In summary, this non-woven fabric production waste gas recovery device achieves a more secure and tight connection between the connecting pipe 2 and the inlet of the waste gas treatment machine 3 by welding two six-hole discs 4 to the surface of the inlet of the waste gas treatment machine 3 and the connecting pipe 2, respectively. Then, small nuts 8 are used to thread the studs 7. Subsequently, the inner rubber ring 9 is placed in the inner cavity of the waste gas treatment machine 3 and the connecting pipe 2. This prevents gaps from forming at the connection between the connecting pipe 2 and the waste gas treatment machine 3.
