Description
Technical field
The utility model relates to a kind of mufflers, and in particular to a kind of intake silencer on Roots blower.
Background technique
Muffler is a kind of device for preventing sound transmission and air-flow being allowed to pass through, and is the weight for eliminating air power noise
Want measure.Intake silencer on Roots blower is mounted in the air inlet of Roots blower, and sieve can be effectively reduced
The aerodynamic noise of thatch air blower, reduces environmental pollution, but in the use site of many Roots blowers, since the space of client is set
Limit especially installs the Ventilator Room limited height of blimp class, and the height of common intake silencer is too high, therefore can not pacify
Dress, and the lower intake silencer of common height is selected, the length of sound-absorbing material is shorter, and erasure effect is bad, and design is not achieved
It is required that.
Utility model content
The technical problems to be solved in the utility model is, in the case where guaranteeing same erasure effect, provide it is a kind of high
Spend the lower intake silencer on Roots blower.
The technical solution of the utility model is to provide a kind of intake silencer on Roots blower, including
First hush pipe, the second hush pipe, the first cartridge filter and the second cartridge filter, the second cartridge filter cover outside the first hush pipe and with
First hush pipe coaxial line, the second cartridge filter and the first hush pipe are connected with bottom plate jointly, are connected with trunnion on bottom plate, trunnion with
The inner cavity of first hush pipe communicates, and the lower end of trunnion is equipped with ring flange, is coaxially arranged with the first cartridge filter on the first hush pipe, the
Two hush pipes are covered outside the first cartridge filter and are pressed on the second cartridge filter, are connected with upper cover at the top of the second hush pipe, are above pressed against
On first cartridge filter, the first hush pipe upper end is connected with supporting plate, and screw rod is connected on supporting plate, and upper cover is inserted on screw rod and uses nut
Locking, the axial length of the first hush pipe are greater than the axial length of the second cartridge filter, and the axial length of the second hush pipe is greater than the
The axial length of one cartridge filter.
Intake silencer described in the utility model on Roots blower, wherein the barrel of the first hush pipe by
It is interior to punched-plate layer, centrifugal glass wool layer and steel plate layer is followed successively by outside, the barrel of the first cartridge filter is followed successively by punching from inside to outside
Plate layer and sponge layer, the barrel of the second hush pipe are followed successively by punched-plate layer, centrifugal glass wool layer and steel plate layer from inside to outside, and second
The barrel of cartridge filter is followed successively by punched-plate layer, sponge layer and punched-plate layer, upper cover from inside to outside and is followed successively by punched-plate from inside to outside
Layer, centrifugal glass wool layer and steel plate layer.
Intake silencer described in the utility model on Roots blower, wherein trunnion is equipped with pressure gauge.
After using the above structure, compared with prior art, the utility model is for the intake silencer on Roots blower
It has the advantage that when the utility model is used, air-flow can enter the second hush pipe after the filtering by the second cartridge filter
It is interior, it after the noise reduction of the second hush pipe, is entered in the first hush pipe using the first cartridge filter, using the first hush pipe
Noise reduction after entered in Roots blower from trunnion, cover since the utility model uses two groups of hush pipes and cartridge filter one
The structure risen, the first hush pipe and the second hush pipe partially overlap in the axial direction, on the first hush pipe and the second hush pipe
The length of total sound-absorbing material does not reduce, and ensure that same erasure effect and has compressed axial length, can make this reality
Lower with the novel height for the intake silencer design on Roots blower, the Ventilator Room height that can adapt to client is not high
The case where.
The pressure gauge that trunnion is equipped with is used to measure the air pressure in trunnion.
Detailed description of the invention
Fig. 1 is schematic view of the front view of the utility model for the intake silencer on Roots blower.
