For the flue gas of the generation in above-mentioned welding process, generally adopt fume cleaning equipment to carry out purified treatment, but when fume cleaning equipment carried out emission gases, due to direct discharging, noise was larger.Can't satisfy some occasion to the requirement of noise, therefore, cause the use of fume cleaning equipment to be subject to certain restriction.And existing there is no a kind of exhaust muffling device that is directly applied for fume cleaning equipment, and can reach and reduce exhaust noise, avoid the exhaust noise of fume cleaning equipment to pollute, enlarge the purpose of fume cleaning equipment usable range.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of exhaust muffling device is provided, improve the erasure effect to exhaust noise in industry.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of exhaust muffling device, comprise casing, be provided with the first dividing plate and second partition in described casing, the upper end of described the first dividing plate and the upper surface of casing form a fixed connection, form the first chamber between the left side wall of described the first dividing plate and casing, be connected with draft tube on the casing of the first chamber upper end, leave the gap between the lower end of the first dividing plate and tank floor;
The lower end of described second partition and the bottom surface of casing form a fixed connection, form the second chamber between the right side wall of second partition and casing, be connected with escape pipe on the casing of the second chamber lower end, leave the gap between the upper end of described second partition and the upper surface of casing, be provided with the 3rd dividing plate on the described casing left side wall that is positioned at the first chamber, be positioned on the right side wall of casing of the second chamber and be provided with the 4th dividing plate, described the 3rd dividing plate and the downward-sloping setting of the 4th dividing plate.
Further, be respectively arranged with sound-absorbing material layer on the left side wall of described casing and right side wall.
Further, described the first dividing plate is provided with sound-absorbing material layer on the surface of the 3rd dividing plate one side, and described second partition is provided with sound-absorbing material layer on the surface of the 4th dividing plate one side.
Further, be connected with damping spring between described the first dividing plate and second partition.By damping spring, effectively limit the vibration of the first dividing plate and second partition.
The beneficial effects of the utility model are: can be through repeatedly turning by being arranged on the first dividing plate and the second partition in casing, making the gas that passes into, and the vibration of buffer gas flow realizes noise reduction to gas.
The 3rd dividing plate and the 4th dividing plate that is inclined in the second chamber in being inclined at the first chamber, the gas that enters from draft tube can directly be impacted on the 3rd dividing plate, turning after impacting continues to impinge upon on the left surface of the first dividing plate, strike on the right surface of fighting back again second partition on the 4th dividing plate with gas flow at last, then discharging from escape pipe, the noise gas that passes into from draft tube is repeatedly turned back through the 3rd dividing plate, the first dividing plate, the 4th dividing plate and second partition, effectively reduces the noise of Exhaust Gas.
And by left side wall, right side wall, the left surface of the first dividing plate and the right surface of second partition at casing, sound-absorbing material layer is set, makes the sound wave after turning back to act on sound-absorbing material layer morning, exhaust noise is realized noise reduction.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the structural representation of quieter;
Wherein: 1, the first dividing plate, 2, second partition, the 3, the 3rd dividing plate, the 4, the 4th dividing plate, 5, casing, 6, sound-absorbing material layer.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
As shown in Figure 1, a kind of exhaust muffling device, comprise casing 5, be provided with the first dividing plate 1 and second partition 2 in described casing 5, the upper surface of the upper end of the first dividing plate 1 and casing 5 forms a fixed connection, form the first chamber between the left side wall of the first dividing plate 1 and casing 5, be connected with draft tube on the casing 5 of the first chamber upper end, leave the gap between the lower end of the first dividing plate 1 and casing 5 bottom surfaces;
