[0035] Reference Figure 1The bottom end of the hanging component 2 is connected to the top of the muffler 1; the length of the hanging component 2 is adjustable, thereby realizing convenient hanging of the muffler 1 at a desired height.

[0036] The muffler 1 is in the shape of a horizontal cylinder, which facilitates its convenient installation with the pipe and the hanging assembly 2.

[0037] Reference Figures 1 to 4 The hanging assembly 2 includes a hanging ear 21 and a hanging rod 22.

[0038] Reference Figures 2 and 3 The lifting lug 21 includes a first vertical plate 211 and a second vertical plate 212 fixedly connected in a T-shape. The first vertical plate 211 is fixedly connected to the side wall of the muffler 1 shell (for example, by welding or by an integral fixed connection), and the second vertical plate 212 is fixedly connected to the side wall of the muffler 1 shell (for example, by welding or by an integral fixed connection). The first vertical plate 211 and the second vertical plate 212 are fixedly connected by welding or by an integral fixed connection. The first vertical plate 211 has a lifting hole 2111; the length of the second vertical plate 212 is arranged along the axial direction of the muffler 1 shell; the length of the first vertical plate 211 is arranged along the radial direction of the muffler 1 shell.

[0039] Reference Figure 1 and Figure 4 The lifting rod 22 includes a snap plate 221, a mounting bolt 222, a rod body 223 and a sleeve 224. The snap plate 221 is an N-shaped plate structure. The bottom end of the rod body 223 is adjustable connected to the top of the snap plate 221 through a thread. The top of the rod body 223 is inserted into the inner cavity of the sleeve 224 and is adjustable connected to the sleeve 224 through a thread. The bottom end of the snap plate 221 is connected to the lifting ear 21 through a mounting bolt 222.

[0040] Reference Figure 1 and Figure 2 The first vertical plate 211 is perpendicular to the outer shell of the muffler 1. The second vertical plate 212 is perpendicular to the outer shell of the muffler 1. The first vertical plate 211 is a rectangular plate structure, and the second vertical plate 212 is a right-angled triangle plate structure.

[0041] Reference Figure 4 and Figure 5 The buckle plate 221 is buckled at the top edge of the first vertical plate 211.

[0042] Reference Figure 4 and Figure 5Mounting holes 2211 are provided on both sides of the bottom wall of the fastening plate 221. The mounting holes 2211 and the lifting holes 2111 are coaxially arranged, and the mounting holes 2211 are arranged in pairs on the left and right sides of the lifting holes 2111. Mounting bolts 222 are inserted into the mounting holes 2211 and the lifting holes 2111. There are two mounting bolts 222, and the two mounting bolts 222 are inserted into the two mounting holes 2211 respectively. There are four lifting holes 2111, and they are arranged in pairs.

[0043] Reference Figure 4 The sleeve 224 includes a T-shaped cylindrical body 2241 and a top plate 2242 that are fixedly connected to each other. The top plate 2242 is fixedly mounted on the top of the cylindrical body 2241 in an integrated manner. Figure 1 and Figure 4 : When the floor 5 adopts a reinforced concrete structure, the sleeve 224 is fixedly installed in the floor 5 in a pre-embedded form. At this time, the cylinder 2241 is inserted into the gap of the steel mesh 51, and the top plate 2242 is press-fitted above the steel mesh 51; when the floor 5 adopts a steel structure, the top plate 2242 is set under the steel beam, so that the top plate 2242 and the steel beam are fixedly connected by a hoop or by bolts.

[0044] Reference Figure 4 The top of the rod 223 is provided with a first external thread, and the bottom of the inner cavity of the barrel 2241 is provided with a first internal thread adapted to the first external thread. The first external thread and the first internal thread are screwed together, and when the rod 223 rotates, it can move along the axial direction of the barrel 2241, thereby changing the relative position of the rod 223 and the sleeve 224.

[0045] Reference Figure 4 and Figure 5 The bottom end of the rod 223 is provided with a second external thread, and the top end of the fastening plate 221 is provided with a first screw hole 2212 adapted to the second external thread. The second external thread is screwed into the first screw hole 2212, and when the rod 223 rotates, it can move longitudinally along the fastening plate 221, thereby changing the relative position of the rod 223 and the fastening plate 221.

[0046] Reference Figure 4 The first and second external threads rotate in opposite directions, so when the rod 223 rotates, the sleeve 224 and the buckle plate 221 can move closer to or farther from each other. The rod 223 has a circular cross-section and a straight rod structure with a constant diameter. The first and second external threads have equal pitch, ensuring smooth rotation of the rod 223.

The upper edge and left and right edges of the support plate 22101 are fixedly connected to the support plate 22101 (for example, through an integrated fixed connection). After the limiting bolt 225 is screwed into the second screw hole 2231, the column head of the limiting bolt 225 presses the support plate 22101, thereby preventing the limiting bolt 225 from accidentally rotating and coming out of the second screw hole 2231, further avoiding the occurrence of safety accidents.

[0050] Reference Figure 8 A rolled fin is provided in the middle of the rod body 223. The user can drive the rod body 223 to rotate by clamping the rolled fin with a tool (such as a wrench, pliers, etc.) and rotating it.

[0051] The air duct of the industrial air supply system includes a first air duct 3 and a second air duct 4 for connecting the muffler 1. The first air duct 3 and the second air duct 4 are coaxially arranged.

[0052] Usage steps: ① Assemble the lifting rod 22 so that the sleeve 224 is fixedly connected to the floor 5; ② Use a lifting tool (such as a scaffold) to lift the silencer 1 to the bottom of the lifting rod 22; ③ Use the mounting bolt 222 to fix the snap plate 221 to the lifting ear 21; ④ Unscrew the limiting bolt 225, and rotate the rod body 223 through the rolled fins so that the utility model can lift the silencer 1; ⑤ When the silencer 1 is coaxial with the first air duct 3 and the second air duct 4, screw the limiting bolt 225 into the second screw hole 2231; ⑥ Use bolts to fix the first flange 31 at the end of the first air duct 3 to the first mounting flange 11 at the end of the muffler 1, and use bolts to fix the second flange 41 at the end of the second air duct 4 to the second mounting flange 12 at the end of the muffler 1.

[0053] The utility model has a simple structure and reliable function. A pulling force is applied to the muffler 1 by a hanging assembly 2 placed upright between the floor 5 and the muffler 1, thereby reducing the pressure transmitted by the muffler 1 to the air duct and the fan, so that the industrial air supply system has excellent structural stability and avoids the occurrence of safety accidents; the relative position of the sleeve 224 and the snap-on plate 221 can be adjusted by rotating the rod body 223, and the height position of the muffler 1 can be fine-tuned, so that the height of the muffler 1 can be adapted to the height of the first air duct 3 and the second air duct 4. While achieving convenient installation, the coaxiality between the first air duct 3, the muffler 1 and the second air duct 4 is improved, thereby avoiding the problem of noise generated by gas flowing along the curved air duct.
