Embodiment Construction

[0021] see Figure 1~5 , in the embodiment of the present invention, a fully sealed muffler includes an upper casing 1, a lower casing 2 is fixedly connected to the bottom of the upper casing 1, and the inner sides of the upper casing 1 and the lower casing 2 are pasted with Sound insulation cotton, sound insulation cotton is a component made of rock wool, which can improve the sound insulation efficiency of the upper and lower shells.

[0022] The upper end of the upper casing 1 is penetrated and fixed with an air intake pipe 7 extending to the inside, and a reinforcement plate 4 is arranged between one side of the air intake pipe 7 and the upper casing 1. The reinforcement plate 4 is a triangular structure, and the reinforcement plate 4 It is fixed with the upper shell 1 by welding to increase the stability and avoid tearing of the joint due to vibration and affect the sealing effect.

[0023] One end of the intake pipe 7 is fixed with a connection plate 6, and the connecti...

Abstract

The invention relates to the technical field of silencers, in particular to a full-sealed silencer. A lower shell is fixedly connected to the lower portion of an upper shell, an air inlet pipe extending into the upper shell is fixed to the upper end of the upper shell in a penetrating manner, and a connecting disc is fixed to one end of the air inlet pipe; and the connecting disc and the air outlet end of an external air cylinder are fixed through a rapid mounting mechanism, and an air outlet pipe extending into the lower shell is fixed to the bottom end of the lower shell in a penetrating manner. The full-sealed silencer is novel in design and ingenious in structure; an integrally-formed structure is adopted to be matched with a welding fixing mode to enable the silencer to be completelyclosed and sealed, and the problem that the silencing effect is poor due to the fact that residual sounds of a traditional silencer exist and are transmitted out along connecting gaps is solved; a preliminary silencing mechanism can effectively reduce and control sound waves generated after gas enters the silencer, so that the whole silencing effect is improved; and the rapid mounting mechanism can achieve the effect of being convenient to dismount and mount, a dismounting and mounting tool is not needed, the mounting difficulty is lowered, and the overall dismounting and mounting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mufflers, in particular to a totally sealed muffler. Background technique [0002] The muffler is a device that prevents sound transmission and allows airflow to pass through, and is an important measure to eliminate aerodynamic noise. The muffler is installed on the air flow channel of aerodynamic equipment (such as blower, air compressor, boiler exhaust, generator, water pump and other equipment with high exhaust noise) or in the intake and exhaust system to reduce noise. device. [0003] However, the silencers currently on the market are all assembled, and the sealing effect is not good, and the reverberation sound will be transmitted from other connection gaps, resulting in poor noise reduction effect. Therefore, those skilled in the art provide a fully sealed muffler to solve the problems raised in the background art above. Contents of the invention [0004] The purpose of the present invention ...
