Description

A kind of noise reduction controller

Technical field

The utility model relates to a kind of noise reduction controller, relates in particular to a kind of generator set noise reduction controller.

Background technique

The noise reduction controller is commonly called as baffler or noise reduction controller, in motive power machine equipment the noise noise is decayed, and reduces its influence to environment, is indispensable a kind of environmental protection parts.

The used noise reduction controller of internal vapor fry dried food ingredients group of motors is the multi-cavity cell structure at present, after air-flow enters from suction port, reflux between each chamber through honeycomb duct, can reach certain buffering, noise reduction erasure effect, the sound-deadening and noise-reducing effect is about can reduce the 15-16 decibel.But because return time is longer, noise reduction controller temperature is too high, and the noise reduction controller architecture complexity of multi-cavity cell structure, the manufacturing process complexity, and materials are many, the cost height.

The model utility content

The technical problems to be solved in the utility model is: reduce the temperature of noise reduction controller, the cost of simple structure and minimizing noise reduction controller simultaneously, guarantees better erasure effect.

In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of noise reduction controller, comprise noise reduction controller inner chamber, suction tude and steam outlet pipe, and wherein, noise reduction controller inner chamber does not have dividing plate; Suction tude one port is a sealing configuration, and the another port is to be arranged on the outer suction port of noise reduction controller inner chamber, is distributed with the suction tude cinclides on the suction tude sidewall in noise reduction controller inner chamber; Steam outlet pipe one port is the seal welding structure, is located in the noise reduction controller inner chamber, and the other end is the air outlet, is located at outside the noise reduction controller inner chamber, is distributed with the steam outlet pipe cinclides on the steam outlet pipe in noise reduction controller inner chamber.

Adopt above technological scheme, because the inner chamber of the noise reduction controller that adopts is single cavity, the time that the waste gas of high-temperature stops in noise reduction controller inner chamber has the multi-cavity chamber of dividing plate relatively and can shorten, and helps reducing the temperature of noise reduction controller; And owing to only adopt single cavity, the internal structure of noise reduction controller is simple, reduce the manufacture cost and the technological requirement of noise reduction controller, simultaneously, this inner chamber body that enters the noise reduction controller from the suction tude cinclides, enter the noise reduction mode of steam outlet pipe again by the steam outlet pipe cinclides, after the flow rate speed of the waste gas that enters and noise and volume carried out twice hole amplification decay, outside uniform small pores ejection noise reduction controller, through and back pressure also can not strengthen, under the prerequisite that does not influence power and use, erasure effect is better.

Further, limiting described suction tude and steam outlet pipe all is solely to manage.Only tubular construction so more helps making and processing, also can better guarantee the sealing of noise reduction controller inner chamber simultaneously, can design different suction tude, steam outlet pipe and suction tude cinclides, steam outlet pipe cinclides according to the power demand of different displacements.

Further, limiting described suction tude cinclides and steam outlet pipe cinclides is the shape of circular hole, and so regular circular hole helps processing and makes.

Further, limit the length enter the suction tude in noise reduction controller inner chamber, limiting described suction tude has 2/3 length in noise reduction controller inner chamber, and such structure can guarantee suction tude and more stable being connected of noise reduction controller.

Same reason, limiting described steam outlet pipe has 5/6 length in noise reduction controller inner chamber.

In order better power plant to be connected with the noise reduction controller, the suction port end of limiting described suction tude is connected with flange.

Further, the distributing position and the mode of suction tude cinclides, steam outlet pipe cinclides limited, limit described suction tude cinclides and be evenly distributed in the noise reduction controller inner chamber on the suction tude sidewall of inner chamber inboard; Described steam outlet pipe cinclides be evenly distributed on steam outlet pipe sidewall in the noise reduction controller inner chamber around on.Such distribution mode, the direction that guarantees the suction tude cinclides ejection waste gas on the suction tude is directly to airtight cavity inboard, can not cause local temperature to improve to the inner chamber outer side wall, thereby reduced the appearance temperature of noise reduction controller, simultaneously, such layout is beneficial to again over against steam outlet pipe, can shorten the flow process of waste gas, the temperature when further reducing the work of noise reduction controller.

Further be limited to the noise reduction controller of above-mentioned any technological scheme, also include the arc guard shield that removably connects with the noise reduction controller.Be provided with the arc guard shield go out to help attractive in appearance outside, more play the effect that preventing that noise reduction controller appearance from scalding, isolating.

The diameter that further limits described suction tude cinclides is 8 millimeters, and the diameter that limits described steam outlet pipe cinclides is 1.5 millimeters or 2.0 millimeters.

Can also limit the concrete shape of described airtight noise reduction controller inner chamber in addition, promptly limiting noise reduction controller inner chamber is that two ends all are the cylinder of arc, the smooth slick and sly surface of such arc cylinder is remarkable to the reflection loss effect of sound, more help reducing noise, play better erasure effect.

In addition, when welding, the port of restriction suction tude sealing is welded on the outer wall of noise reduction controller, and such welded structure helps welding on the one hand, helps fixedly suction tude.

Technical solutions of the utility model advantage be: the utility model noise reduction controller operating temperature is low, good muffling effect, simple in structure, manufacturing process is simple, and is with low cost, is worthy of popularization.
