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 present invention relates to the technical field of mufflers, in particular to a totally sealed muffler. The lower part of the upper case is fixedly connected with the lower case, and the upper end of the upper case is penetrated and fixed with an air intake pipe extending into the interior thereof. One end of the air inlet pipe is fixed with a connection plate, and the connection plate is fixed with the air outlet end of the external cylinder by a quick installation mechanism, and the bottom end of the lower casing is fixed with an air outlet pipe extending to the inside. The invention has a novel design and an ingenious structure. It adopts an integrally formed structure combined with a welding and fixing method to make the muffler completely sealed and sealed, which solves the problem that the residual sound of the traditional muffler is transmitted along the connection gap, resulting in poor muffler effect. The preliminary muffler mechanism can eliminate gas The sound waves after entering are effectively reduced and controlled, which improves the overall noise reduction effect. The quick installation mechanism can facilitate disassembly and assembly without disassembly tools, which reduces the difficulty of installation and improves the overall disassembly efficiency.

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 ...
