Abstract
The utility model discloses a silencer comprising an upper cover, an exhaust pipe, a positioning column, a separating plate, a catalyst seat, a catalyst, a fire baffle plate, a cushion block and a lower cover. The lower cover is provided with an air inlet; the upper cover is provided with an air outlet; a diversion groove is formed between the exhaust pipe and the upper cover; the diversion groove is communicated with the air outlet; diversion space is formed between the exhaust pipe and the lower cover; the diversion space is communicated with the air inlet; and the diversion groove is communicated with the diversion space. With the diversion groove and the diversion space in the silencer, after exhaust enters the silence, the exhaust successively passes through the diversion space and the diversion groove, so the exhaust is introduced out; secondary diversion is conducted to the exhaust entering the silencer and great noise elimination effect is provided; the exhaust can stay long in the silencer and can be fully burned, so emission value of poisonous gas is reduced; and with an increase of a sparkle capturing net, sparkles in the exhaust can be prevented from emitting outside the silencer, so potential fire accidents are prevented.
Description
Technical field
The utility model relates to a kind of silencing apparatus.
Background technique
Silencing apparatus is mainly used in the motor such as petrol engine, diesel engine, for reducing the noise of motor, in prior art, the tail gas of motor discharge is to enter by the inlet hole of baffler, then through the catalyst in the middle of being arranged on, finally discharge from air outlet hole, the trend of tail gas is one directly discharges, and intermediate structure is simple, gas is only through a guide flow noise elimination, and soundproof effect is poor; While, tail gas was not fully burned in silencing apparatus because the time that tail gas stops in silencing apparatus is short, and discharge value is higher, has in addition spark to be directly discharged into outside by silencing apparatus, is easy to cause fire.
Summary of the invention
It is good that the technical problems to be solved in the utility model is to provide a kind of soundproof effect, emission effect good and prevent fire occur silencing apparatus.
For addressing the above problem, the utility model adopts following technological scheme: a kind of silencing apparatus, comprise upper cover, and the outlet pipe that is arranged on upper cover inside and is connected with upper cover, and run through the locating column of outlet pipe, and the dividing plate being connected with outlet pipe, and be arranged on the catalyst seat above dividing plate, and be arranged on the catalyst of catalyst seat inside, and be arranged on the flame-isolating board of dividing plate below, and the cushion block that runs through of the post that is positioned, and the lower cover being connected with cushion block; Described lower cover is provided with suction port, and described upper cover is provided with air outlet; Between described outlet pipe and upper cover, form guiding gutter, described guiding gutter is connected with air outlet, between described outlet pipe and lower cover, forms diversion space, and described diversion space is connected with suction port, and described guiding gutter and diversion space communicate.
As preferably, described locating column has been horizontally disposed with two, and connects upper cover and lower cover simultaneously.
As preferably, described lower cover is connected with location piece.
As preferably, described upper cover outer installment has the exhaust shell being connected with upper cover, and exhaust enclosure is provided with Mars catching net.
The beneficial effects of the utility model are: this silencing apparatus is owing to being provided with guiding gutter and diversion space, tail gas enters after silencing apparatus, successively through diversion space and guiding gutter, make the outflow of tail gas guided bone, the tail gas entering in silencing apparatus has been carried out to secondary water conservancy diversion, and soundproof effect is good, and because tail gas waiting time in silencing apparatus is long, can make tail gas fully burn, noxious gas emission value reduces; Increase a Mars catching net, stop the spark in tail gas to be discharged to outside by silencing apparatus, reduce the hidden danger of breaking out of fire.
Accompanying drawing explanation
Fig. 1 is the explosive view of a kind of silencing apparatus of the utility model.
Embodiment
Consult shown in Fig. 1, a kind of silencing apparatus, comprise upper cover 14, and the outlet pipe 5 that is arranged on upper cover 14 inside and is connected with upper cover 14, and run through the locating column 6 of outlet pipe 5, and the dividing plate 9 being connected with outlet pipe 5, and be arranged on the catalyst seat 7 of dividing plate 9 tops, and be arranged on the catalyst 8 of catalyst seat 7 inside, and be arranged on the flame-isolating board 10 of dividing plate 9 belows, and the cushion block 11 that runs through of the post 6 that is positioned, and the lower cover 12 being connected with cushion block 11; Described lower cover 12 is provided with suction port 13, and described upper cover 4 is provided with air outlet 14; Between described outlet pipe 5 and upper cover 12, form guiding gutter, described guiding gutter is connected with air outlet 14, between described outlet pipe 5 and lower cover 3, forms diversion space, and described diversion space is connected with suction port 13, and described guiding gutter and diversion space communicate.
Described locating column 6 has been horizontally disposed with two, and connects upper cover 4 and lower cover simultaneously.Described lower cover 12 is connected with location piece 3.Described upper cover 4 outer installment have the exhaust shell 1 being connected with upper cover 4, and exhaust shell 1 inside is provided with Mars catching net 2.
The beneficial effects of the utility model are: this silencing apparatus is owing to being provided with guiding gutter and diversion space, tail gas enters after silencing apparatus, successively through diversion space and guiding gutter, make the outflow of tail gas guided bone, the tail gas entering in silencing apparatus has been carried out to secondary water conservancy diversion, and soundproof effect is good, and because tail gas waiting time in silencing apparatus is long, can make tail gas fully burn, noxious gas emission value reduces; Increase a Mars catching net, stop the spark in tail gas to be discharged to outside by silencing apparatus, reduce the hidden danger of breaking out of fire.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement all should be encompassed in the new protection domain of this practicality and be as the criterion.
