Embodiment

[0038] A muffler, see figure 1 , which includes a support tube 1, the support tube 1 is a rectangular cylinder-shaped structure; the two end walls of the support tube 1 are correspondingly provided with several support rods 2, and the support rods 2 are vertically fixed on the support tube 1 by screws; A muffler tube 3 is arranged between each group of support rods 2 to reduce noise; an airflow gap 11 is left between adjacent muffler tubes 3 for the airflow to pass through the support tube 1 in time.

[0039] refer to figure 2 with image 3 , the muffler tube 3 is formed by bending a perforated plate. Since the wall of the muffler tube 3 has several small holes, the airflow can enter the muffler tube 3 in time; the inner wall of the muffler tube 3 is provided with melamine sound-absorbing Cotton layer 31; at the same time, centrifugal glass wool 32 is arranged in the muffler cylinder 3 for reducing noise.

[0040] refer to figure 2 with Figure 4 , Both ends of the muff...

Abstract

The invention discloses a silencer, and the silencer comprises a support cylinder. Two end walls of the support cylinder are correspondingly provided with a plurality of groups of supporting rods. Silencing cylinders are respectively disposed between the groups of supporting rods, and two ends of each silencing cylinder are respectively are respectively provided with fairing caps connected with the supporting rods. Each support rod is provided with a fixed groove in a width direction, and the directions of the notches of the fixed grooves of the support rods are consistent. The fairing caps at two ends of each silencing cylinder are respectively provided with a fixing part which can be inserted into the corresponding fixed groove so as to fix the silencing cylinder. The main points of the technical scheme of the invention are that an operator carries the silencer and enables the silencer to move the fixed grooves when the silencing cylinders need to be fixed; the fixed parts at two ends of each silencing cylinder are respectively inserted into the corresponding fixed grooves, thereby completing the fixing of the silencing cylinders; Compared with the prior art, the silencer can complete the installation of the silencing cylinders through screwing up a plurality of screws, and achieves an effect of facilitating the installation of the silencing cylinders.

Description

technical field [0001] The present invention relates to a noise reducing device, more particularly, it relates to a muffler. Background technique [0002] A muffler is a device that allows airflow to pass through, but can prevent or reduce sound transmission; it is an effective tool for controlling noise. [0003] The Chinese patent with the existing authorized notification number CN206134243U provides an array type muffler, which includes a shell and several support rods, and the support rods are all vertically fixed on the two end walls of the shell; the support rods at both ends of the shell are respectively a One to one correspondence. There are a number of muffler unit modules inside the shell, and the muffler unit modules are also called mufflers; the wall of the muffler is a perforated plate to allow airflow to enter the muffler; the inner wall of the muffler is provided with a dense The urethane sound-absorbing cotton layer, at the same time, the centrifugal glass ...
