Abstract
The invention relates to a scalding-preventing device of a silencer of a single-cylinder air-cooled diesel engine. The scalding-preventing device is characterized in that a left inner side plate is provided with a left outer side plate; the left inner side plate and the left outer side plate are fixed on the left of a silencer; an asbestos plate is adhered to the surface of the silencer; an innerupper cover and an outer upper cover are fixed on the silencer; and a right inner side cover and a right outer side cover are fixed on the right of the silencer. The scalding-preventing device has simple, compact and reasonable structure and is produced by additionally arranging two layers of insulating protecting covers on the shell of the original silencer of the single-cylinder air-cooled diesel engine, wherein the first layer of protecting cover is made of 0.5m/m steel plate, a piece of asbestos insulating cloth is adhered to the inner side of the first layer of protecting cover, and the second layer of protecting cover is made of high-temperature resistant engineering plastic, therefore, the temperature on the surface of the silencer is reduced from the original 200 DEG C to blow 80 DEG C, and the human body can not be scaled by the silencer.
Description
Technical field
The present invention relates to a kind of scalding-preventing device of silencer of single-cylinder air-cooled diesel engine, especially a kind of anti-high temperature of small-sized single cylinder air-cooled diesel engine silencing apparatus is scalded a kind of device of human body.
Background technique
In existing technology, the main consideration of acoustic wave filter structure design of single-cylinder air-cooled diesel engine reduces engine noise, the surface is reduced the temperature aspect only installed the layer of metal thermal shield additional on the silencing apparatus surface, so its surperficial temperature reaches more than 200 ℃, in use be easy to scald human body, have a strong impact on personal safety.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, thereby a kind of scalding-preventing device of silencer of single-cylinder air-cooled diesel engine is provided, the silencing apparatus temperature is dropped to below 80 ℃, reached the purpose that prevents the safe handling of human body scald.
According to technological scheme provided by the invention, scalding-preventing device of silencer of single-cylinder air-cooled diesel engine comprises left side inner panel, silencing apparatus, interior loam cake and right inner side lid, feature is: on the described left side inner panel left-external side plate is housed, left-external side plate and left side inner panel are fixed on the left side of silencing apparatus, asbestos slate sticks on the surface of silencing apparatus, loam cake and outer loam cake are fixed on the silencing apparatus in described, and described interior loam cake and outer loam cake are fixed on the silencing apparatus, and right inner side lid and right outboard cover are fixed on the right side of silencing apparatus.
Compared with the prior art the present invention has the following advantages:
The present invention is simple, compact and reasonable for structure; On former single-cylinder air-cooled diesel engine muffler shell, install two layers of heat-insulating shield additional, wherein the first layer protecting cover is made with the 0.5m/m steel plate, the inboard asbestos insulation cloth that pastes, second layer protecting cover is that thermostability engineering plastic is made, make the silencing apparatus surface temperature from original dropping to below 80 ℃ more than 200 ℃, reached and prevent to scald the human body purpose of safety.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:
As shown in Figure 1, comprise hexagon socket head cap screw 1, left-external side plate 2, left side inner panel 3, silencing apparatus 4, asbestos slate 5, interior loam cake 6, outer loam cake 7, right inner side lid 8, right outboard cover 9, hexagon socket head cap screw 10 and hexagon socket head cap screw 11 etc.
On the described left side inner panel 3 left-external side plate 2 is housed, left-external side plate 2 and left side inner panel 3 are fixed on the left side of silencing apparatus 4 by two M6 hexagon socket head cap screws 1, asbestos slate 5 fastens with glue on the surface of silencing apparatus 4, loam cake 6 and outer loam cake 7 are fixed on the silencing apparatus 4 in described, interior loam cake 6 and outer loam cake 7 are fixed on the silencing apparatus 4 by six M6 hexagon socket head cap screws 11, and right inner side lid 8 and right outboard cover 9 are fixed on the right side of silencing apparatus 4 by two hexagon socket head cap screws 10.
In the above-mentioned parts, left-external side plate 2, right outboard cover 9,7 three parts of outer loam cake are made with thermostability engineering plastic, and asbestos slate 5 usefulness asbestos are made, and all the other are the 0.5m/m steel plate and make except that hexagon socket head cap screw.
The use principle of silencing apparatus of the present invention:
Waste gas after the engine cylinder-body internal combustion, discharge through exhaust valve, because producing serious noise during its exhaust reaches more than 150 decibels, high temperature reaches more than 450 degree, after effect by the inner noise elimination baffle plate that is provided with of silencing apparatus and thermal shield are isolated its noise is dropped to about 100 decibels, surface temperature drops to about 200 degree, and this patent mainly is the New Scheme that designs at reducing surface temperature.
