Abstract
The utility model relates to a filtering silencer, which comprises an upper cover and a lower cover. The upper cover is provided with an air inlet, the bottom of the lower cover is connected with a pipe joint, and the inner bottom of the lower cover is provided with a sound guide barrel. The utility model is characterized in that the center part of the top of the upper cover is provided with a via hole, and a threaded rod passes through the via hole along the axial direction and is connected with the top of the sound guide barrel. The filtering silencer has the advantages that the fastening reliability is high, the fastening mode is simple and feasible, and the cost is low.
Description
The utility model relates to a kind of filtering silencing apparatus, is specially adapted to the filtering silencing apparatus of mechanical industry air compressor.
Existing air compressor filtering silencing apparatus generally comprises loam cake, lower cover, and the loam cake place offers suction port, and lower cover bottom connecting tube joint, is led cylinder record etc. at the built-in sound-absorbing vibration absorber of silencing apparatus, filter plate, filter core.Usually people adopt welding button lobe, fastening anchor ear or alternate manner in addition fastening to upper and lower cover, but this fastening means built on the sand, and reliability is low, easily causes the upper and lower cover double swerve, and technology is many, make complicatedly, and cost of production is higher.And under the continuous shaking state, the button lobe of upper and lower cover causes the filtering silencing apparatus to damage easily by the pine that shakes.
The purpose of this utility model is at the above-mentioned problems in the prior art, provides a kind of fastening reliability height, the filtering silencing apparatus that fastening means is simple, cost of production is low.
The technical solution of the utility model is as follows:
Air compressor filtering silencing apparatus comprises loam cake, lower cover, lower cover bottom Tube to tube fittings, and the lower cover inner bottom part is established and is led cylinder record, and loam cake is established suction port, and center, loam cake top has via hole, and a screw rod passes via hole vertically and links to each other with the cylinder record top of leading in the lower cover.The loam cake port is to peripheral hardware tongue seam, and the lower cover port is established O shape limit, and two-port is tangent.
Compare with existing filtering silencing apparatus, the utlity model has following advantage:
1. this filtering silencing apparatus adopts screw rod to connect upper and lower cover vertically, the central axes of screw rod present position and upper and lower cover port, thereby this kind Placement can produce an axial pressure to upper and lower cover, pressure evenly and firmly, can avoid the filtering silencing apparatus double swerve or the upper and lower cover phenomenon that gets loose to take place, guarantee the reliability of using in when vibration.
2. this filtering silencing apparatus has outwards rolled the tongue seam in the loam cake port, and O shape limit is rolled in the lower cover port, and two-port is tangent.This mode of structure cooperates with the screw axial Placement, has more strengthened the steadiness that upper and lower cover connects.
3. this filtering silencing apparatus only has screw rod to realize being fastenedly connected of upper and lower cover, and is simple in structure, and assembling is fast, and cost is low, also makes things convenient for user's demolition and maintenance simultaneously.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Embodiment: as shown in Figure 1, this filtering silencing apparatus comprises loam cake 1, loam cake 14, lower cover 14 bottom Tube to tube fittingss 13, lower cover 14 inner bottom parts are established and are led cylinder record 10, lead cylinder record 10 overcoat filter cores 9, establish filter plate 6 between the upper and lower cover 1,14, establish sound-absorbing vibrationproof foam 5 in the loam cake 1.Loam cake 1 side middle part has suction port 8, and center, loam cake 1 top is established via hole 7, one screw rods 4 and passed via hole 7 vertically and link to each other with cylinder record 10 tops of leading in the lower cover 14, and screw rod 4 two ends usefulness nut 2, packing ring 3 are fastening, thereby upper and lower cover 1,14 is linked together.Upper and lower cover 1,14 two-port are tangent, and the loam cake port has outwards rolled tongue seam 11, and the lower cover port has rolled O shape limit 12, and upper and lower cover all adopts drawing.
Claims (2)
1. an air compressor filtering silencing apparatus comprises loam cake, lower cover, and loam cake is established suction port, lower cover bottom connecting tube joint, the lower cover inner bottom part is established and is led cylinder record, it is characterized in that center, loam cake top is provided with via hole, and screw rod passes via hole vertically and leads the cylinder record top and link to each other.
2. air compressor filtering silencing apparatus according to claim 1 is characterized in that the loam cake port to peripheral hardware tongue seam, and the lower cover port is established O shape limit, and two-port is tangent.
