Abstract
The utility model relates to an exhaust muffler for a heavy engineering self-dumping truck, which comprises a circular tube-shaped muffler casing and a muffle cavity, wherein the muffle cavity is arranged in the muffler casing; an air inlet is arranged at one radial side of the muffler casing and is connected with an exhaust pipeline by adopting a flange face; and an exhaust heat-insulating plate is arranged on one axial end surface of the muffler casing and is connected with the muffler casing through bolts. A horizontal air outlet is arranged at the lower side part of the exhaust heat-insulating plate. The exhaust muffler is characterized in that: by changing the exhaust direction of an exhaust port, the design cost is reduced and the phenomenon that dust raises because wind from the exhaust port blows towards the ground can be avoided; and meanwhile, the exhaust back pressure is reduced and the dynamic property of a engine is enhanced. By additionally arranging the exhaust heat-insulating plate, the injury on persons or the damage to other objects due to exhausted hot air can be avoided. The air inlet is connected with the exhaust pipeline by adopting the flange face, so that the exhaust muffler has stronger reliability and the phenomenon that the air leaks during exhaust can be avoided.
Description
Technical field
The utility model relates to automobile exhaust muffler, specifically heavy engineering dumping car exhaust silencer.
Background technique
At present, the exhaust outlet direction of the exhaust silencer of most of homemade heavy engineering dumping car is under the side direction, and engineering dump truck running environment is all many dusts operating mode, so gas will blow to ground after the silencing apparatus relief opening is discharged, cause very big dust, surrounding environment is caused very big influence.In addition, relief opening requires the silencing apparatus outlet must design one section vent connection under side direction, flows to guiding gas, can cause cost to increase like this.Secondly because of having increased vent connection, also increased the exhaust back pressure of silencing apparatus.Change this situation, just must change the exhaust mode of exhaust silencer.
Summary of the invention
In order to change of the influence of engineering dump truck exhaust silencer to environment, reduce cost, reduce exhaust back pressure, the utility model provides a kind of novel exhaust silencer.
Concrete architecture advances technological scheme is as follows:
A kind of heavy engineering dumping car exhaust silencer comprises the suppressor case 1 and the silencing cavity 2 of tubular shape; Described silencing cavity 2 is arranged in the suppressor case 1, and radially a side is provided with suction port 3 to suppressor case 1, suction port 3 adopts flanged surface to be connected with gas exhaust piping; Described suppressor case 1 an axial end face is equipped with exhaust thermal baffle 5, and the side-lower of exhaust thermal baffle 5 is provided with air outlet 4.
Exhaust thermal baffle 5 is connected with suppressor case 1 by bolt.
Suppressor case and exhaust thermal baffle adopt cold rolled sheet DC04 material.
Useful technique effect of the present utility model is embodied in the following aspects:
1, the exhaust mode of exhaust silencer by the row of changing under side outside side, the appearance of a large amount of airborne dusts when having avoided vehicle operating.
2, exhaust silencer case side end face has been installed the exhaust thermal baffle, can avoid hot gas damage personnel or other objects of discharging.
3, suction port adopts flanged surface to be connected with gas exhaust piping, and this Placement reliability is stronger, can not produce gas leak phenomenon.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the left view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1, Fig. 2, a kind of heavy engineering dumping car comprises that with exhaust silencer suppressor case 1, the inner silencing cavity 2 of silencing apparatus, silencing cavity 2 are arranged in the suppressor case 1, and radially a side is provided with suction port 3 to suppressor case 1, suction port 3 adopts flanged surface to be connected with gas exhaust piping; Described suppressor case 1 an axial end face is equipped with exhaust thermal baffle 5, and the side-lower of exhaust thermal baffle 5 is provided with air outlet 4(and sees Fig. 3).
Exhaust airstream enters silencing apparatus silencing cavity 2 by suction port 3, and after expansion, resonance and interfering, sound wave is in propagation process middle impedance mismatch, and generation is reflected or interfered in pipeline and resonant cavity, and acoustic energy reduces, and exhaust airstream is arranged in air by air outlet 4.
Silencing apparatus thermal baffle 5 is connected with suppressor case 1 by bolt, and exhaust silencer housing 1 is connected with outlet pipe by flange 6.
Exhaust silencer housing and exhaust thermal baffle material are DC04.
The utility model is used for the heavy engineering dumping car, and the appearance of a large amount of airborne dusts when both having avoided vehicle operating has reduced cost again, has reduced exhaust back pressure, has strengthened engine power performance, and the reliability of exhaust silencer is also more intense.
