Abstract

The invention discloses an inner blowtorch capable of reducing noise, belonging to the field of environment-protection equipment. The inner blowtorch comprises a bottom plate, a vertical plate, an oblique plate and an inner baffle plate, wherein the bottom plate is an annular plate; the vertical plate is welded on the outer circle of the bottom plate; the oblique plate is welded on the inner circle of the bottom plate and is welded to the other end of the vertical plate; and the inner baffle plate is welded in a cavity which is defined by the bottom plate, the vertical plate and the oblique plate. The inner blowtorch has the beneficial effects that the inner baffle plate with flow control holes is arranged in the cavity, so that high-pressure gas is subjected to multiple times of flow control through the flow control holes which are irregularly formed in the inner baffle plate; and compared with the audio frequency in a mode that the high-pressure gas directly passes through flow control holes in the oblique plate, the audio frequency can be lowered.

Description

A kind of interior blow gun that can reduce noise
Technical field
The present invention relates to field of environment protection equipment, be specifically related to a kind of interior blow gun that can reduce noise.
Background technology
Environmental protection at present becomes the emphasis that entire society pays close attention to, and environmental protection is very urgent, and noise pollution is always the difficulty of enterprise governance Topic, and administer means that noise taked at present also mainly around taking sound insulation means or adding the deafener stage, occur big Noise, do not tackle the problem at its root, but use periphery to add at protective cover or gas outlet interpolation deafener, but the biggest Most equipment are not suitable for installing protective cover and deafener, although some equipment with the addition of protective cover, and workman inside works, to body The heart causes greatly injury, and adding deafener also will affect workpiece work, by the inner surface that uses most enterprises Blow gun in reason equipment, measures, and finds the gas that compressed air blows out from interior blow gun at 0.3-0.6MPa, and its noise is surveyed Amount has just reached the value that 80-110 decibel does not waits, and people locates to work under such circumstances for a long time, tinnitus etc., and health damages becomes Normality, enterprise's peripheral cell complaint is also gradually increased, and noise pollution is extremely urgent for enterprise, and a lot of enterprises face because of noise Environmental issue and stop production, in order to solve the problems referred to above, the most undesirable by using frequency-conversion valve etc. to control the effect such as the amount of blowing of gases. Finally by deafener internal structure research, this device is combined with microperforated panel noise elimination structure, is not reducing postpartum mastitis pressure Situation, repetition test, blow gun internal structure in changing, in the case of the force value not affecting the gas being blown out, reduce Noise during air blowing, and the most also do not have such device to occur.
Summary of the invention
For the problem existing for blow gun noise refractory reason in prior art, the present invention provide a kind of can reduce noise in blow Mouth, i.e. can ensure that blow gas pressure, in tolerance band, can meet again criteria for noise.
To achieve these goals, the technical solution used in the present invention is as follows: a kind of interior blow gun that can reduce noise, including protecgulum And bonnet, it being provided with air intake lever after described protecgulum, described air intake lever is provided with some air inlets, and there is through hole described bonnet center, Described bonnet is coordinated with the multidiameter on air intake lever after protecgulum by through hole, makes protecgulum and bonnet be buckled together and is internally formed cavity, Some flow control plates it are provided with in described cavity.
Described protecgulum front end is cavity, and inwall is provided with female thread, described air intake lever inner hollow, described air inlet even circumferential Being distributed in before air intake lever, air inlet size and quantity change with interior blow gun diameter.
On described protecgulum, even circumferential is distributed some gas holes, and described gas hole direction becomes 45-60 angle with front capping.
Described bonnet is cavity, and what the outer wall of bonnet was provided with external screw thread, described protecgulum and bonnet fits through platform in bonnet cavity Multidiameter on rank and protecgulum air intake lever carrys out location sealing.
A kind of interior blow gun that can reduce noise, including protecgulum and bonnet, described protecgulum front end is plectane, and described bonnet is cavity, Described protecgulum and bonnet are buckled together and are internally formed cavity and form seam of blowing between protecgulum and bonnet.
The described angle blowing seam becomes 45-60 degree with front capping.
Described protecgulum and bonnet fix some flow control plates in being buckled together the cavity of formation, described flow control plate is thin-wall circular ring flat-plate, institute State flow control plate different at least provided with two pieces and every piece of flow control board diameter.
Described flow control plate is provided with flow control hole, and described flow control hole quantity on flow control plate is held according to the diameter of flow control plate and successively decreased Trend.
As preferred technical scheme, described flow control plate includes that outer flow control plate and interior flow control plate, described outer flow control board diameter are more than Interior flow control board diameter, having cavity, the flow control hole number on described interior flow control plate between described flow control plate is the flow control on outer flow control plate The twice of hole number.
As preferred technical scheme, the flow control hole on described each flow control plate is crisscross arranged.
The flow control plate having the beneficial effect that different-diameter with different number flow control holes of this invention in cavity, gases at high pressure Can rise by the flow control hole on outermost layer flow control plate after diameter ever-reduced flow control plate, number the most ever-increasing flow control hole To the effect of repeatedly flow control, comparing directly by gas hole on interior blow gun, audio frequency can reduce;If this interior blow gun only adds in inside The dry flow control plate with flow control hole, protecgulum and bonnet are combined, easy to process, and noise reduction highlights, gas hole and seam of blowing Having a certain degree with protecgulum, when inside blowing, impurity surpasses a direction discharge.
