Technical Field

[0001] The present application relates to the field of mufflers, and in particular to a detachable and cleanable muffler. Background Art

[0002] With the development of the times and the continuous improvement of living standards, population concentration is becoming more and more serious, and the noise from industrial enterprises and social life is increasing. Noise pollution is increasingly affecting people's living, life and study, and even seriously affects human mental health. Therefore, most of the aerodynamic noise equipment in the society currently needs to use mufflers to reduce noise.

[0003] However, with the use of silencers, the porous silencer plates inside the silencers are easily clogged by dust or gas debris, affecting the use effect. However, the traditional silencer is installed and connected by a flange and multiple bolts, which makes disassembly and assembly inconvenient and affects the disassembly and assembly efficiency. In addition, the fixed number of porous silencer plates arranged inside affects the silencing effect. Utility Model Content

[0004] In order to make up for the above shortcomings, the present application provides a detachable cleaning muffler, aiming to improve the problems raised in the above background technology.

[0008] In a specific embodiment, the connecting pipe is conical, and the connecting pipe and the connecting plate are integrally formed, and the connecting plate is provided with a plurality of mounting holes.

[0009] In the above implementation process, by setting a tapered connecting pipe, when the gas enters the gas equipment connected to the connecting plate, the aperture becomes larger, thereby slowing down the flow rate and reducing the impact force to achieve a certain noise reduction effect. The mounting holes on the connecting plate are used to cooperate with bolts to install and connect to the equipment pipe mouth.

[0010] In a specific embodiment, an external threaded ring is provided at one end of the connecting pipe away from the connecting disk, and the sleeve is threadedly sleeved on the surface of the external threaded ring.

[0012] In a specific implementation manner, a strip-shaped groove is provided in the sleeve, a sliding block is provided on the outer side of the fixing frame, and the sliding block is slidably disposed in the strip-shaped groove.

[0013] In the above implementation process, the sliding fit between the slider and the groove is provided to stabilize the position of the fixing frame when it is inserted, thereby preventing the multiple fixing frames from rotating and rubbing against each other inside.

[0014] In a specific embodiment, a protrusion is provided in the strip-shaped groove, and the adjusting bolt thread passes through the protrusion.

[0015] In the above implementation process, a protrusion is arranged in the strip groove for threading the adjusting bolt so that the passing adjusting bolt can abut against the sliding block, thereby pressing and fixing the porous muffler plate and the fixing frame.

[0017] In a specific embodiment, the axial thickness of the porous sound-absorbing plate is smaller than the axial thickness of the fixing frame.

[0018] In the above implementation process, when multiple porous sound-absorbing panels and fixed frames overlap and dock, the ends of adjacent fixed frames contact and abut, so that intervals are formed between adjacent porous sound-absorbing panels to avoid the holes being easily blocked due to the adjacent porous sound-absorbing panels being attached.

[0019] In a specific embodiment, an anti-slip ring is provided on the outer side of the sleeve.

[0020] In the above implementation process, the anti-slip ring is provided to increase the friction force, so as to facilitate the rotation when the sleeve is disassembled and assembled.

[0021] Beneficial effects: The present application provides a detachable and cleanable silencer.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0029] See also Figure 1-Figure 4 The present application provides a detachable cleaning muffler including a connecting assembly 100 and a muffler assembly 200.

[0030] See also Figure 1 , 23. The connection assembly 100 includes a connection pipe 110, a connection plate 120 and a sleeve 130. The connection plate 120 is arranged at one end of the connection pipe 110, and the sleeve 130 is threadedly sleeved on the other end of the connection pipe 110.

[0031] Among them, the connecting pipe 110 is conical, and the connecting pipe 110 and the connecting plate 120 are of an integrally formed design, and the connecting plate 120 is provided with a plurality of mounting holes 121. By setting the conical connecting pipe 110, when the gas enters the gas equipment connected to the connecting plate 120, the aperture becomes larger, thereby slowing down the flow rate and reducing the impact force to achieve a certain noise reduction effect. The mounting holes 121 on the connecting plate 120 are used to cooperate with bolts to be installed and connected to the equipment pipe mouth.

[0032] In a specific implementation manner, an anti-skid ring 133 is disposed on the outer side of the sleeve 130 . By providing the anti-skid ring 133 , the friction force is increased, and the rotation of the sleeve 130 is facilitated when disassembling or assembling the sleeve 130 .

[0033] See also Figure 1 , 3 and 4, the silencer assembly 200 includes a porous silencer plate 210, a fixed frame 220 and an adjusting bolt 230, the porous silencer plate 210 is fixedly connected in the fixed frame 220, and the porous silencer plate 210 and the fixed frame 220 are overlapped and arranged in multiple numbers, the fixed frame 220 is slidably arranged in the sleeve 130, the adjusting bolt 230 is threadedly connected in the sleeve 130, and one end of the adjusting bolt 230 abuts against the porous silencer plate 210.

[0034] In a specific implementation scheme, an external threaded ring 140 is provided at one end of the connecting pipe 110 away from the connecting plate 120, and the sleeve 130 is threadedly sleeved on the surface of the external threaded ring 140. By providing the external threaded ring 140, the sleeve 130 is threadedly sleeved and connected to the external threaded ring 140, so that the porous sound-absorbing plate 210 and the fixed frame 220 are pressed between the inner wall of the sleeve 130 and the end of the external threaded ring 140.

[0035] In this embodiment, a strip groove 131 is opened in the sleeve 130, and a slider 221 is set on the outside of the fixed frame 220. The slider 221 is slidably set in the strip groove 131. By setting the sliding cooperation between the slider 221 and the strip groove 131, it is used to stabilize the position of the fixed frame 220 when it is inserted, and avoid the rotation and friction between multiple fixed frames 220 inside.

[0036] Among them, a protrusion 132 is arranged in the strip groove 131, and the adjusting bolt 230 is threaded through the protrusion 132. By setting the protrusion 132 in the strip groove 131, it is used to thread through the adjusting bolt 230, so that the passed adjusting bolt 230 can abut against the slider 221, thereby pressing and fixing the porous sound-absorbing plate 210 and the fixing frame 220.

[0037] In a specific embodiment, the porous sound-absorbing plate 210, the fixing frame 220 and the protrusion 132 are integrally formed, and the integrally formed design has a higher structural strength and is more stable.

[0038] It should be noted that the axial thickness of the porous sound-absorbing plate 210 is smaller than the axial thickness of the fixed frame 220. When multiple porous sound-absorbing plates 210 and the fixed frame 220 overlap and dock, the ends of adjacent fixed frames 220 contact and abut, so that a gap is formed between adjacent porous sound-absorbing plates 210, thereby preventing adjacent porous sound-absorbing plates 210 from being easily clogged due to the fit of the holes.

[0039] The working principle of the detachable cleaning silencer is as follows: during use, the connection is installed to the equipment pipe mouth through the mounting hole 121 on the connecting plate 120 by bolts. When the incoming gas enters the tapered connecting pipe 110, the aperture becomes larger, thereby slowing down the flow rate, reducing the impact force to achieve a certain noise reduction effect, and then flows through the porous silencer plate 210. The gas flow rate and air pressure are further slowed down by multiple obstructions of the porous silencer plate 210, thereby achieving a noise reduction effect. After long-term use, the anti-slip ring 133 is rotated to drive the sleeve 130 to rotate, and the sleeve 130 is removed from the external threaded ring 140 in a threaded manner, and the porous silencer plate 210 and the fixed frame 220 are poured out for cleaning without removing the flange, which greatly improves the disassembly and assembly efficiency. At the same time, the pressure distance of the fixed frame 220 on the outside of the fixed frame 220 is adjusted by rotating the adjusting bolt 230, so that the number can be increased or decreased for installation and fixing. The number of thin sheets can be increased according to needs to improve the noise reduction effect, further improving practicality.

Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application.
