Description

Technical Field

[0001] The invention relates to the field of air filters, and in particular to a salt mist filtering device. Background Art

[0002] In humid and salt-fog areas, such as offshore platforms, ships, coastal areas and other occasions that require ventilation, the corrosion damage of water vapor and salt fog to the inside of the equipment can be alleviated by purifying the air, thereby increasing the service life of the equipment. The salt spray filter has the function of dehumidification and efficient isolation of salt. The internal filter element material is very soft. During installation and use, attention should be paid to the protection of each filter layer. The existing structure does not provide enough protection for each filter layer, which is easy to cause damage to the filter layer. In addition, the opening of the filter device is mostly removed from the entire surface and then fixed with screws and nuts, which is troublesome to disassemble. Screws and nuts are also often used to fix the filter layers. Because they need to be frequently inspected and replaced, quick installation and quick disassembly are more convenient. Therefore, it is a more urgent issue to provide a salt spray filter device that can be quickly disassembled and installed, and has a more solid structure. Utility Model Content

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] In the present utility model, unless otherwise clearly specified and defined, terms such as "installation", "connection", "linkage", "fixation" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral body; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0018] As shown in the figure, a salt spray filtering device includes a housing 1. An air inlet 11 is provided on one side of the housing 1, and an air outlet 12 is provided on the side opposite to the air inlet 11. The air inlet 11 and the air outlet 12 form a duct with a straight-through structure, and the straight-through type has less air resistance. The side of the housing 1 adjacent to the air inlet 11 is a side door. One side of the side door is hinged to the housing 1. The side door facilitates the replacement of the filter layer and the cleaning of the device, without the need to fix the four sides with screws. When the side door is opened, the upper fixing plate 13 is connected to the top inner wall of the housing 1 by screws and nuts, and the lower fixing plate 14 is connected to the bottom inner wall of the housing 1 by screws and nuts. A water mist separator 2, a primary filter 3, and a salt spray removal device 4 are arranged layer by layer inside the housing 1. The water mist separator 2 can isolate water and mist in the air outside the device, usually made of aluminum alloy louvers. The primary filter 3 is generally made of coarse fiber mesh to filter larger particles and dust. The salt spray removal device 4 is composed of multiple layers of dense fiber materials. It can physically filter and intercept tiny salt spray particles in the air on the surface of the material because the fiber material has a high surface area and can effectively adsorb and capture particulate matter. The upper fixing plate 13 and the lower fixing plate 14 are both provided with three groups of convex blocks 5. An I-shaped chute 51 is formed between each group of convex blocks 5. Each convex block 5 is provided with a concave limiting member 52 at one end close to the side door. The concave limiting member 52 is fixed in the middle of the convex block 5. The top and bottom of the water mist separator 2, the primary filter 3, and the salt spray removal device 4 are both provided with protrusions 6 adapted to the I-shaped chute 51. As Figure 2 shown, taking the salt spray removal device 4 as an example, the protrusion 6 and the I-shaped chute 51 have the same length. The protrusion 6 can slide along the I-shaped chute 51 in a matching manner. One end of the protrusion 6 close to the side door is provided with a rotatable flap 61. The flap 61 can be rotated into the concave limiting member 52, and the flap 61 is movably connected to the middle of the protrusion 6. Moreover, the length L of the flap 61 is less than or equal to the height H of the protrusion 6, and L is greater than the width D of the protrusion 6, that is, D < L ≤ H. The water mist separator 2, the primary filter 3, and the salt spray removal device 4 are installed layer by layer inside the housing 1 through their respective protrusions 6 cooperating with the corresponding I-shaped chutes 51, and the three filter layers are respectively installed in the corresponding positions. At this time, the flap 61 is rotated 90 degrees, and the flap 61 changes from the vertical direction to the horizontal direction. During the process of the flap 61 becoming horizontal, it is rotated into the concave limiting member 52, and the concave limiting member 52 limits the flap 61 to make the structure more firm.

[0019] The mist and water separator 2, the primary filter 3 and the salt mist removal device 4 are provided with a protective layer 7 on the opposite sides of the wind direction or on the air inlet side. The protective layer 7 is connected to the outer side of the protrusion 5 by screws and nuts. The protective layer 7 can be a stainless steel wire mesh. The setting of the protective layer 7 does not affect the air intake volume. At the same time, it reduces the pressure of wind force on each filter layer, which can make the structure more solid and extend the service life of the filter layer.

[0020] The lower fixing plate 14 is hingedly connected to the corresponding protrusion 5. When there are debris or crystals in the shell 1 that need to be cleaned, the protrusion 5 can be directly lifted to clean the bottom. The upper fixing plate 13 is fixedly connected to the corresponding protrusion 5, so that the top structure is more solid.

[0021] When maintenance is needed, open the side door, check the filter layer layer by layer to see if it is intact, and close the side door after the inspection. If the filter layer needs to be replaced or cleaned, open the side door, rotate the baffle 61 in the upper and lower concave stoppers 52 from horizontal to vertical, and pull out the corresponding filter layer along the straight groove 51. If the debris deposited at the bottom needs to be cleaned, lift the corresponding protrusion 5 of the lower fixed plate 14 to clean it, and restore it after cleaning. The new filter layer is pushed into the housing 1 along the straight groove 51. In order to be more secure, rotate the baffle 61 90 degrees from the vertical direction and place it horizontally on the corresponding concave stopper 52 to further fix the filter layer. Each filter layer structure of the utility model is provided with a stainless steel wire mesh, which not only reduces the pressure of wind on the filter layer, but also makes the whole structure more solid. The straight-line chute 51 formed by the two protrusions 5 cooperates with the protrusion 6 for faster assembly and disassembly. The protrusion 5 and the protrusion 6 are provided with mutually cooperating concave stoppers 52 and baffles 61, and the filter layer can be fixed in the housing 1 without using an additional fastening structure. In summary, the utility model can solve the problems raised in the background technology and is a more practical salt spray filter device.
