Description

Technical Field

[0001] The utility model relates to the technical field of air filtering equipment, in particular to a reinforced oil removal filter. Background Art

[0002] The oil removal filter is mainly composed of a cyclone separation section, an inertial demister pre-filter box, a fine filter element, a drain valve, a pressure and temperature gauge. The compressed air carrying oil and water enters the deoiler from the air inlet pipe in a tangential direction. After cyclone separation, part of the liquid oil and water are separated. Then, the gas is further separated from the liquid by inertial collision. After the pre-filter box, the dust with larger particle size in the gas is filtered out, which protects the subsequent fine filter element. When the gas passes through the fine filter element, solid particles with a particle size greater than 1 micron are filtered out, and the oil mist and water mist with a tiny particle size are collected on the fine filter element and condensed into larger droplets. Under the action of gravity, they settle to the bottom of the fine filter tube. The separated oil and water are discharged from each drain port, and the compressed air treated with oil removal is output from the air outlet at the top of the deoiler. It can be widely used in the process gas of pneumatic control, pneumatic instruments and pneumatic components in chemical, metallurgy, energy, light industry, electronics, pharmaceuticals, food, cigarettes, cement, petroleum, textile and other industries, providing high-quality pure compressed air and special design and services for users.

[0003] Traditional oil mist removal filters not only have low filtration efficiency, but also after repeated flushing and reuse, the gas-liquid network in the middle that plays a filtering role will shrink, resulting in a gap between the outer frame, which further reduces the filtration efficiency. In addition, it is difficult to install and disassemble, and the subsequent cleaning effect is not good. Utility Model Content

[0020] Embodiment 1

[0021] like Figure 1 As shown, a reinforced oil removal filter includes an outer frame 1 and an inner frame 2. A first protective net 3, a pre-filter element 4, a fine filter element 5, and a second protective net 6 are installed between the outer frame 1 and the inner frame 2 from top to bottom. The pre-filter element 4 and the fine filter element 5 can improve the efficiency of segmented coarse and fine filtration of oil and dirt without residue. A plurality of sliders 11 are arranged around the first protective net 3, the pre-filter element 4, the fine filter element 5, and the second protective net 6. The sliders 11 can facilitate the installation and fixing of the first protective net 3, the pre-filter element 4, the fine filter element 5, and the second protective net 6 on the inner frame 2. The first protective net 3 and the second protective net 6 protect the pre-filter element 4 and the fine filter element 5 respectively, which can extend the service life of the filter.

[0022] The outer frame 1 is provided with a fixing assembly 7 on all sides. The fixing assembly 7 includes a rotating shaft and a fixing block. The rotating shaft is provided with a locking assembly. A first through hole is provided on the lower side of the fixing assembly 7. Second through holes 8 are provided on both ends of the outer frame 1. Figure 2 As shown, the outer sides of the inner frame 2 are all provided with fixing grooves 9 matching the fixing assembly 7, and the inner frame 2 is provided with oil drain outlets 10 matching the second through holes 8 at both ends. The first through hole of the outer frame 1 corresponds to the position of the fixing groove 9 of the inner frame 2, and the second through hole 8 of the outer frame 1 corresponds to the position of the oil drain outlet 10 of the inner frame 2. When the outer frame 1 is mounted on the inner frame 2, the fixing block of the fixing assembly 7 is rotated into the fixing groove 9 of the inner frame 2, and the locking assembly is locked to the fixing assembly 7, so that the outer frame 1 and the inner frame 2 can be connected and fixed.

[0023] Several slide grooves 12 matching the slider 11 are provided on the edges of the inner cavity of the inner frame 2. The slider 11 is a dovetail slider 11, and the slide groove 12 is a dovetail slide groove 12. By designing the slider 11 and the slide groove 12 as dovetail grooves, it is convenient for installation and avoids falling off, thereby causing leakage. The height of the slide groove 12 is higher than the sum of the heights of the sliders 11 of the first protective net 3, the pre-filter element 4, the fine filter element 5, and the second protective net 6. Embedded fixing strips 13 are provided around the top of the inner frame 2. The two ends of the fixing strips 13 are connected and fixed to the inner frame 2 by screws. The fixing strips 13 are embedded in the top of the inner frame 2 to avoid hindering the installation of the inner frame 2 and the outer frame 1.

[0024] A conical frame 14 is provided inside the inner frame 2. The first protective net 3, the pre-filter element 4, the fine filter element 5, and the second protective net 6 are all conical. Through the conical design, the oil can be quickly discharged from the oil discharge port 10 without partial residual stagnation, thereby improving the filtering effect. The height of the outer frame 1 is higher than the sum of the heights of the inner frame 2, the first protective net 3, the pre-filter element 4, the fine filter element 5, and the second protective net 6. The outer frame 1, the inner frame 2, the first protective net 3, the pre-filter element 4, the fine filter element 5, and the second protective net 6 are all made of stainless steel. Stainless steel can enhance the overall stability of the filter, and the pre-filter element 4 will not shrink or deform during repeated use or flushing, which can avoid leakage.

[0025] Therefore, the utility model adopts the above-mentioned enhanced oil removal filter, which can enhance the overall stability of the filter, and the pre-filter element will not shrink or deform during repeated use or flushing, thereby preventing leakage. The service life is extended, and the maintenance cost is reduced. At the same time, the efficiency of oil pollution is improved through segmented coarse and fine filtration, and no residue will appear. The overall installation and disassembly are convenient, and the later cleaning effect is improved.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
