[ detailed description ] embodiments
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The utility model discloses a compressed air impurity filtering device, as shown in figure 1, including the inner tube 8 and the outer tube 3 of coaxial setting, inner tube 8 passes through connecting piece 6 fixed mounting on outer tube 3, forms compressed air circulation space between inner tube 8 and the outer tube 3. To ensure that the compressed air is entirely circulated from the circulation space, the inlet end of the inner tube 8 is closed.
The end of giving vent to anger of inner tube 8 passes through connecting piece 6 and is connected with the end of giving vent to anger of outer tube 3 to realize the connection between inner tube 8 and the outer tube 3 and fix, can select welding also can select bolted connection or riveting etc. according to actual conditions specifically selection.
because the filtering device is applied to a compressed air transmission pipeline, in the embodiment, the diameter of the transmission pipeline is 50mm, in order to ensure the stable air pressure in the pipeline, the pipe diameter of the outer sleeve 3 is selected to be larger than that of the transmission pipeline, so that the compressed air circulates from an air circulation space without changing the pressure, in the embodiment, the diameter of the outer sleeve 3 is selected to be 100mm, the length of the outer sleeve is 200mm, the diameter of the inner pipe is 40mm, and the length of the inner pipe is slightly smaller than that of the outer sleeve 3. After the pipe diameter of the outer sleeve 3 is enlarged, the outer sleeve is connected with a transmission pipeline, therefore, the air inlet end of the outer sleeve 3 is connected with the air inlet reducer 1 through the flange 2 (the reducing is 100mm to 50mm in the embodiment), the air outlet end is connected with the air outlet reducer 4 through the flange 2 (the reducing is 100mm to 50mm in the embodiment), and a through compressed air flowing space is formed inside the outer sleeve 3, the air inlet reducer 1 and the air outlet reducer 4.
As shown in fig. 2, in this embodiment, a connection mode between the inner tube 8 and the outer sleeve 3 is provided, a step (the step width is 10mm in this embodiment) is provided on the inner tube wall at the air outlet end of the outer sleeve 3, and the end of the connecting member 6 is connected with the step through a connecting bolt 9 (the bolt diameter is 6mm in this embodiment). In order to ensure the circulation of the compressed air, the connecting piece 6 can be selected from a straight rod, a support frame formed by the straight rod or an annular support frame provided with a circulation hole, so that the circulation of the compressed air is prevented from being interfered. The connecting piece 6 is connected with the step, so that the contact area is increased, and the connection strength can be ensured.
The inner tube 8 is sleeved with a filter screen group, the filter screen group is arranged in the air circulation space, the edge of the filter screen group is propped against the inner wall of the outer sleeve 3, and the filter screen group is used for removing impurities of compressed air flowing through the compressed air circulation space. Filter screen group establishes the filter screen 7 on inner tube 8 by a plurality of parallel sleeves and constitutes, is a plurality of filter screens 7 with the filter screen component (filter screen middle part thickness is 6mm in this embodiment, edge thickness is 1.5mm, the filter screen number is 25), on the one hand compressed air will once flow through each filter screen 7, flow through a lot of layers of filter screens 7, must increase filterable precision, on the other hand, with filter screen group split into a plurality of filter screens 7 also can make things convenient for the later stage to filter screen 7's cleanness, alleviate maintenance work volume.
As shown in fig. 3, each of the filter screens 7 is ring-shaped (ring width is 30mm in this embodiment), and is sleeved on the outer wall surface of the inner pipe 8, and as shown in fig. 4, the thickness thereof is uniformly increased from the middle to the edge, so that a gap is formed between the edge portions of two filter screens 7, which is beneficial to the circulation of compressed air in the filter screen group, and if many filter screens are arranged close to each other, the circulation speed of compressed air may be affected, and a situation of blockage is likely to occur. Further, the plurality of screens 7 are thickest in the middle, and the edge portions thereof are certainly spaced after being pressed. All evenly arrange and be covered with filtration pore 10 (filtration pore diameter is 1mm in this embodiment) on every filter screen 7, compressed air circulates away through filtration pore 10, and impurity generally can be bigger than filtration pore 10, can block on filter screen 7, consequently, has played the effect of filtering impurity, after working a period, can open the flange of device inlet end, tears locating part 5 open, takes out filter screen 7 one by one and cleans, gets rid of impurity.
