Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment 1
A kind of compressor liquid storage device, its structure as shown in Figure 1, comprise housing 2, air inlet pipe 3, escape pipe 4 and filter assemblies, air inlet pipe 3 to be located on housing 2 and to be communicated with housing 2, escape pipe 4 is located on housing 2, comprises and stretches into the straight tube in housing 2 and the bend pipe outside reservoir, and filter assemblies is located in housing 2, be positioned at below housing 2 air inlet, above straight tube.Also comprise a hollow cylindrical structure in addition, be axially provided with the perforated plate 1 of via-hole array, its structure as shown in Figure 2, this perforated plate 1 is arranged with the escape pipe 4 in housing 2 is concentric, and it is inner that perforated plate 1 is arranged on housing 2, and leave certain interval between housing 2 inwall.
In the present embodiment, perforated plate 1 is fixedly connected with bottom filter assemblies and housing 2 respectively.
In individual preferred embodiment more of the present invention, perforated plate 1 is short vertical clapboard structure, and as shown in Figure 2, the distance between perforated plate 1 is highly less than bottom filter assemblies and housing 2, is fixed on the position between filter assemblies and housing bottom.Perforated plate can be arranged on escape pipe 4 and be positioned on the pipeline of housing 2, is fixed in the middle part of reservoir.Perforated plate 1 also can one or both ends and housing 2 madial wall be connected and fixed.
In another preferred embodiment of the present invention, perforated plate 1 is long vertical clapboard structure, and as shown in Figure 3, one end is connected with case top through filter assemblies, and the other end is connected with housing bottom.
The through hole that perforated plate 1 is offered can be lack of alignment, the ordered arrangement that also can be left and right and anyhow align, through-hole diameter≤6mm, number of openings >=6, through-hole diameter is 1: 15 with the external diameter ratio of cylinder perforated plate 1, distance between adjacent two through holes is the twice of through-hole diameter, and via-hole array line number is 1: 2 with the ratio of columns.That adopt in the present embodiment is the aperture 45mm of the perforated plate 1 adding vertical clapboard structure, perforated plate 1, and perforate in the middle part of dividing plate, aperture 3mm, pitch-row is greater than 6mm, hole count 12*6=72.
Frequency noise in housing 2 and the spacing between perforated plate 1 and housing 2 inwall are inversely proportional to, namely when in reservoir, frequency noise is larger, the external diameter of cylinder perforated plate 1 wants corresponding increase, reduces the spacing between housing 2 inwall, to reach more good sound-deadening and noise-reducing effect.
Embodiment 2
A kind of compressor liquid storage device, substantially the same manner as Example 1, difference is, to reduce on perforated plate 1 through-hole diameter to 1mm and following, the thickness of perforated plate is reduced to 1.5mm and following, forms microperforated panel noise elimination structure, can have good acoustically effective in broad frequency band.
