[0024] The following describes exemplary embodiments of the present invention in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0025] like Figure 1 As shown, an embodiment of the present utility model proposes a silencer for medical waste treatment equipment, comprising: a shell 1; an air inlet 6 arranged at the first end of the shell 1, the air inlet 6 being connected to the steam-water separator of the medical waste treatment equipment; an air outlet 7 arranged at the second end of the shell 1, the air outlet 7 being connected to the exhaust fan of the medical waste treatment equipment; at least one inner tube 5 fixedly connected to the air inlet 6; and a sleeve 4 fixedly arranged around the inner tube 5.

[0026] In this embodiment, Figure 1As shown, the silencer for medical waste treatment equipment is provided with an air inlet 6 and an air outlet 7, wherein the air inlet 6 is connected to the steam-water separator of the medical waste treatment equipment. During the medical waste treatment process, more gas is discharged from the steam-water separator, and the noise generated is relatively large. The gas discharged from the steam-water separator enters the silencer through the air inlet 6 to reduce the gas noise; the air outlet 7 is connected to the exhaust fan of the medical waste treatment equipment, and the gas treated by the noise reduction of the silencer is discharged through the exhaust fan; the air inlet 6 and the air outlet 7 adopt flanges or other connection methods to connect with the pipeline; the silencer for medical waste treatment equipment must have at least one inner tube 5, which can be connected when necessary. Multiple inner tubes 5 can also be set. Setting multiple inner tubes 5 can improve the performance and processing capacity of the muffler; when the circulating steam after high-temperature disinfection of medical waste enters the muffler through the air inlet, it first passes through the muffler inner tube 5. The special shape and structure of the muffler inner tube 5 change the flow speed and direction of the steam, increase the resistance of the air flow and the number of sound reflections, thereby reducing the intensity of the noise. In the process of steam flowing in the muffler inner tube, part of the sound is absorbed by the silencer cotton sleeve 4, further reducing the intensity of the noise. The treated steam is discharged from the air outlet or recycled, and the noise is effectively reduced.

[0027] like Figure 1 As shown, in an optional embodiment of the present invention, the muffler for medical waste treatment equipment further includes: a sound insulation layer 2 fixedly arranged around the sleeve 4.

[0028] In this embodiment, Figure 1 As shown, the sound insulation layer 2 is arranged on the inner side of the shell 1. The sound insulation layer 2 can reduce the outward propagation of sound and improve the overall sound insulation effect of the muffler.

[0029] like Figure 1 As shown, in an optional embodiment of the present invention, the muffler for medical waste treatment equipment further includes: a waterproof layer 3 arranged between the sound insulation layer 2 and the sleeve 4.

[0030] In this embodiment, Figure 1 As shown, the waterproof layer 3 is arranged between the sound insulation layer 2 and the sleeve 4. The waterproof layer 3 can prevent moisture in the steam from penetrating from the sleeve 4 to the sound insulation layer 2 and the shell 1, reducing the moisture level of the sound insulation layer 2 and the shell 1, improving the working environment and extending the service life.

[0031] like Figure 1 As shown, in an optional embodiment of the present invention, the muffler for medical waste treatment equipment further includes: a first exhaust port 8 arranged at the bottom of the shell 1.

[0032] In this embodiment, Figure 1As shown, a first exhaust port 8 is provided at one end of the bottom of the shell 1 near the air inlet 6. When the air intake of the air inlet 6 is too large, the first exhaust port 8 can discharge excess steam to reduce the pressure inside the muffler and avoid damage to the muffler when the air intake is too large.

[0033] like Figure 1 As shown, in an optional embodiment of the present invention, the muffler for medical waste treatment equipment further includes: a second exhaust port 9 arranged at the bottom of the shell 1.

[0034] In this embodiment, Figure 1 As shown, a second exhaust port 9 is provided at one end of the bottom of the shell 1 near the air outlet 7. When the air outlet 7 fails to discharge steam in time, the second exhaust port 9 can discharge excess steam to reduce the pressure inside the muffler and avoid damage to the muffler when the amount of steam is too large.

[0035] like Figure 1 As shown, in an optional embodiment of the present invention, the inner tube 5 is a porous cylindrical shape.

[0036] In this embodiment, Figure 1 As shown, the inner tube 5 is a cylinder with holes evenly distributed on the surface. Steam enters the cylinder and is discharged from the holes. The holes can increase the resistance of the air flow and the number of sound reflections, thereby producing a sound-absorbing and noise-reducing effect.

[0037] In an optional embodiment of the present invention, the inner tube 5 is in a porous spiral shape.

[0038] In this embodiment, the inner tube 5 is spiral-shaped with holes evenly distributed on the surface. Steam enters the spiral and is discharged from the holes. The spiral shape with holes can increase the resistance of the airflow and the number of sound reflections, thereby producing a sound-absorbing and noise-reducing effect.

[0039] In an optional embodiment of the present invention, the sleeve 4 is made of sound-absorbing cotton.

[0040] In this embodiment, the sleeve 4 is located inside the shell 1 and wrapped around the outer layer of the inner tube 5. It is made of high-quality high-temperature resistant sound-absorbing cotton material and has good sound absorption performance and high-temperature resistance. The shape and size of the sound-absorbing cotton sleeve match the shell and can be tightly installed in the shell to improve the sound-absorbing effect. The sound-absorbing cotton sleeve can adopt a multi-layer structure to increase the sound absorption area and thickness and improve the sound-absorbing performance.

[0041] In an optional embodiment of the present invention, the sound insulation layer 2 is made of rock wool.

[0042] In this embodiment, the sound insulation layer 2 is located inside the shell 1 and is made of high-quality high-temperature resistant rock wool material, which has good sound insulation performance and high temperature resistance; the shape and size of the rock wool sound insulation layer match the shell and can be tightly installed inside the shell to improve the sound insulation effect. The rock wool sound insulation layer can adopt a multi-layer structure to increase the sound insulation area and thickness and improve the sound insulation performance.

[0043] In an optional embodiment of the present invention, the housing 1 is made of stainless steel.

[0044] In this embodiment, the housing 1 is preferably made of 304 stainless steel. Stainless steel housings have excellent corrosion resistance, high temperature resistance, and strength, and are suitable for the harsh working environment of circulating steam after high-temperature sterilization of medical waste. The housing adopts a modular design for easy disassembly and assembly.

[0045] When the silencer used in medical waste treatment equipment is in use, when the circulating steam after high-temperature disinfection of medical waste enters the muffler through the air inlet, it first passes through the inner tube of the muffler. The special shape and structure of the inner tube of the muffler changes the flow speed and direction of the steam, increases the resistance of the airflow and the number of sound reflections, thereby reducing the intensity of the noise; in the process of steam flowing in the inner tube of the muffler, part of the sound is absorbed by the silencer cotton sleeve, further reducing the intensity of the noise; the waterproof layer can prevent moisture in the steam from contacting the sound insulation layer and the shell, preventing mold and corrosion; the rock wool sound insulation layer plays a role of sound insulation, preventing sound from propagating outward, and improving the overall sound insulation effect of the muffler. The treated steam is discharged from the outlet or recycled, and the noise is effectively reduced.

[0046] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles described in the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
