Abstract
The invention discloses a silencer of a gasoline generator, and in particular relates to a silencer of a generator. The silencer of the gasoline generator comprises a left case, a right case and an intake pipe, and is characterized in that outer edges of an additionally arranged left partition board and an additionally arranged right partition board are buckled and riveted between ring sides of the outer edges of the left case and the right case; cavities, which are jointed correspondingly, are formed in the middle lower parts of the two partition boards, two semicircular blind pipes, which are respectively arranged on the two partition boards on the right sides of the cavities, form a tubular cavity of a return pipe, which is provided with two sealed ends, and the semicircular blind pipes of the left partition board and the right partition board are respectively provided with a backflow air inlet and a backflow air outlet; the air inlet and the air outlet are separately arranged on the two ends of the return pipe, the upper parts of the two partition boards are respectively provided a semicircular single-end-closed blind pipe in opposite directions, the two semicircular single-end-closed blind pipes constitute an exhaust pipe, an exhaust port is arranged on the wall of the semicircular single-end-closed blind pipe of the right partition board, corresponding semicircular holes are formed at positions, which are corresponding to a pipe mouth of the exhaust pipe, of the left case and the right case, and the two semicircular holes are tightly buckled on the outer circle of the exhaust pipe. The airflow orderly flows in the cases along a left partition cavity, the return pipe and a right partition cavity to form three-cavity bending reflow, and a silencing effect is good.
Description
Technical field:
The present invention relates to the generator silencing apparatus.
Background technique:
Existing minitype gas dynamotor is used for building office space, small-sized market, fitting-out work etc. more, and working environment is in people's state is arranged, and the gasoline engine generator noise is big, thereby requires random installation that silencing apparatus is arranged.
Existing silencing apparatus is made up of casing, suction tude, outlet pipe.Casing is formed by left box body, the riveting of right case button.The left box body structure is an opening rectangular box to the right, and its opening is an angular cut, ring limit, an outer of the outside disjunctor extension of angular cut, and ring limit, outer periphery one circle of disjunctor extension is to the right again detained the limit.The right case structure is an opening rectangular box left, and its opening is an angular cut, ring limit, an outer of the outside disjunctor extension of angular cut.After fitting in ring limit, casing outer, the left and right sides, the button limit of left box body is riveted inwardly, and ring limit, the outer bag of right case is detained in it, forms the cavity casing.Fixing suction tude of perforate welding on sidewall of left box body, suction tude partly stretches into the cavity exposed parts and is communicated with the petrol engine relief opening, and fixing outlet pipe is also welded in perforate on the right case sidewall.The high temperature unburnt gas that the petrol engine cylinder is discharged gets into cabinets cavity by suction tude earlier and does simple the backflow, is discharged by outlet pipe again.The residual air burning also takes place in unburnt gas simultaneously in inner chamber, send new noise source.Because air-flow is only done simple backflow, so de-noising effect is poor.
Summary of the invention:
The objective of the invention is to overcome above-mentioned deficiency, a kind of silencing apparatus of gasoline engine generator is provided.
Scheme of the present invention is: comprise left box body, right case, suction tude; It is characterized in that: have additional left clapboard, right clapboard; Two dividing plate gabarits are concordant with ring limit, right case outer; Two its outers of dividing plate applying are buckled riveting and encircled between the limit with the right case outer at left box body: two dividing plate middle and lower parts are provided with the cavity of the triangular-section of corresponding applying, on two dividing plates in cavity right side, are respectively arranged with corresponding reverse semicircle blind pipe, and two semicircle blind pipes form the reflow pipe tubular cavity of two sealing; Left clapboard semicircle blind pipe is provided with a backflow suction port, and right clapboard semicircle blind pipe is provided with a backflow air outlet; Suction port and air outlet split reflow pipe two; Two dividing plate tops are respectively arranged with the blind pipe of corresponding reverse semicircle single head sealing; The blind pipe of two semicircle single head sealings forms an outlet pipe; The blind pipe tube wall of right clapboard semicircle single head sealing is provided with a relief opening, is provided with corresponding semicircle orifice at left box body, right case corresponding to the outlet pipe nozzle position, and two semicircle orifices are held on the cylindrical of outlet pipe.
The invention has the advantages that: air-flow forms three chamber bendings along left separate space, reflow pipe, right separate space successively and refluxes in casing, it is effective to eliminate the noise.Two punching press steel plates form separate space, reflow pipe, outlet pipe geometrical construction, design the ingenious work simplification that makes, and fabricating cost reduces.

Embodiment:
The present invention includes left box body 1, right case 2, suction tude 5; It is characterized in that: have additional left clapboard 3, right clapboard 4; Two dividing plate gabarits are concordant with ring limit, right case 2 outers, and riveting is buckled between left box body 1 and ring limit, right case 2 outers in two its outers of dividing plate applying; Two dividing plate middle and lower parts are provided with the cavity of corresponding triangular-section of fitting; On two dividing plates in cavity right side, be respectively arranged with corresponding reverse semicircle blind pipe; Two semicircle blind pipes form reflow pipe 6 tubular cavity of two sealing; Left clapboard 3 semicircle blind pipes are provided with a backflow suction port 8, and right clapboard 4 semicircle blind pipes are provided with a backflow air outlet 9; Suction port and air outlet split reflow pipe 6 two; Two dividing plate tops are respectively arranged with the blind pipe of corresponding reverse semicircle single head sealing; The blind pipe of two semicircle single head sealings forms an outlet pipe 7; The blind pipe tube wall of right clapboard 4 semicircle single heads sealing is provided with a relief opening 10, is provided with corresponding semicircle orifice at left box body 1, right case 2 corresponding to outlet pipe 7 nozzle positions, and two semicircle orifices are held on the cylindrical of outlet pipe 7.
Two dividing plates are fitted and are formed the casing internal partition, make it to form left and right sides separate space.And the reflow pipe 6 that two dividing plates form simultaneously will advance from this backflow suction port 8 in reflow pipe 6 earlier when making air-flow get into right separate space by left separate space, and the air outlet 9 of refluxing from the other end goes out, and reflow pipe 6 becomes another road separate space, and the backflow runner has extended.The air-flow commute makes noise elimination effective.
Utilize original structure to add two punching press steel plates and form separate spaces, double pipe structure, make work simplification, otherwise to consider separate space with two-tube how to lay be connected, part is many again, structure and complex process many.This also is an innovative point of the present invention.
It is in order to strengthen two mechanical strengths in the dividing plate that two dividing plate middle and lower parts are provided with the triangular-section cavity, and dividing plate can be tabular for full sheet, but the complete tabular not only mechanical strength of sheet is low and also under vibrational state the sheet panel vibration can cause new noise source.
