Description

Technical Field

[0001] The utility model relates to the technical field of kerosene filtering, and more specifically, to a kerosene filtering device. Background Art

[0002] Jet fuel is mainly used in civil aviation aircraft and needs to maintain a high degree of cleanliness. Normally, after jet fuel is discharged from storage and transportation facilities, its cleanliness needs to be evaluated. Only jet fuel that is sufficiently clean and free of impurities is allowed to be recycled and reused. However, in most cases, there are accumulated impurities at the bottom of the oil discharge pipe, in the oil tank or in the filter's sump, such as water or solid particle impurities, which will contaminate the oil and cause the oil to fail to meet the recycling standards. In some cases, when equipment such as oil pumps, coarse filters or flow meters need to be repaired and maintained, the oil inside will be temporarily extracted. Improper operation during the process or improper storage of the oil after extraction can also cause external contamination of the oil.

[0003] Contaminated oil products need to be filtered before they can be recovered. The commonly used filtering method at this stage is to place the oil products for a long time so that the water and impurities inside the oil products can fully settle to the bottom by their own weight, and then pour the clean oil products on the top into the oil recovery device, the oil products with more impurities on the bottom into the dirty oil tank, and the oily wastewater at the bottom into the oil separator for sewage treatment. This treatment method has the following problems: First, the operation is cumbersome and time-consuming, and the separation efficiency is low. Second, some solid impurities have a small density or are similar to the density of oil products. Affected by buoyancy, they may be suspended in the oil products or float on the surface of the oil products, and cannot be separated by sedimentation. Third, the method of separating clean oil products and impurities by dumping is difficult to operate. During the dumping process, when approaching the oil-water interface or the solid impurity deposition section, it is very easy to pour water and solid impurities into the oil recovery device together with the oil products. If the dumping is stopped at a position far away from the oil-water interface or the solid impurity deposition section, there is a problem of incomplete recovery of oil resources. Utility Model Content

[0004] The utility model provides a kerosene filtering device to overcome the defects of the prior art in that the existing oil filtering is complicated, time-consuming and has low separation efficiency, thereby shortening the operation time and improving the separation efficiency.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a kerosene filtering device, comprising: a support seat, a first bracket and a second bracket respectively connected to the support seat, a first filter component connected to the first bracket, a second filter component connected to the second bracket, and an oil storage component arranged below the second filter component, the second filter component is located below the first filter component, and the first filter component and the second filter component are respectively used to filter solid impurities and moisture.

[0006] The first filter assembly is arranged above the second filter assembly, and kerosene is poured into the first filter assembly. Under the action of gravity, the kerosene is filtered by the first filter assembly and the second filter assembly in turn, and then falls into the oil storage part to complete the filtration of the kerosene. Compared with the traditional static sedimentation filtration treatment, the filtration time of the device is shorter and the filtration efficiency is higher. At the same time, the first filter assembly and the second filter assembly filter solid impurities and moisture respectively, fully ensuring the filtration effect, improving the filtration quality, and also improving the cleanliness of the filtered kerosene. The filtration effect and filtration efficiency can also be flexibly adjusted by using filter elements or filter screens of different densities. When the degree of kerosene pollution is general, a sparse filter screen or filter element can be used to improve the filtration efficiency. When the degree of kerosene pollution is serious, a dense filter screen or filter element can be used to ensure the filtration effect. Further, the first filter assembly and the second filter assembly are both detachably connected to the support seat, and any one of them can be used alone for filtering, or multiple filters can be installed for filtering.

[0007] Preferably, the first filter assembly includes a first funnel piece connected to the first bracket and a first filter basket movably disposed in the first funnel piece, and the second filter assembly includes a second funnel piece connected to the second bracket and a second filter basket movably disposed in the second funnel piece, and the bottoms of the first funnel piece and the second funnel piece are both provided with funnel openings, the funnel openings of the first funnel piece are located above the second filter basket, and the funnel openings of the second funnel piece are located above the oil storage piece.

[0008] Kerosene is put into the first filter basket, and after filtering, it falls into the first funnel, and then passes through the second filter basket and the second funnel in sequence, and finally falls into the oil storage part. The first filter basket and the second filter basket are used to increase the filter area and improve the filtering efficiency. The first funnel and the second funnel are used to gather kerosene so that the kerosene can fall accurately into the next part. Compared with filtering with a filter element, the above setting has a much higher filtering efficiency. Furthermore, the first funnel and the second funnel have similar appearances, both of which are a ring structure plus a funnel structure, the ring structure is located at the top, and the funnel structure is located at the bottom. The appearance of the first filter basket and the second filter basket pair is also similar to that of the first funnel and the second funnel. Specifically, the filter net of the first filter basket is attached with filter cotton by bundling or bonding. The filter cotton is composed of specially treated polyester-cotton fibers and other synthetic materials, which can filter out solid particle impurities in the oil. The filter net of the second filter basket is attached with a metal wire mesh sprayed with Teflon or other hydrocarbon-philic and hydrophobic substances by bundling or bonding, which can filter out moisture in the oil. Furthermore, both the first filter basket and the second filter basket can use the coalescing filter element replaced by the filter separator as filter material, saving costs. The first filter basket is movably arranged in the first funnel member, which means that the first filter basket is detachably connected to the first funnel member, and the second filter basket is also detachably connected to the second funnel member.

[0009] Preferably, the second filter assembly further includes a blocking member, a drain outlet is provided at the bottom of the second filter basket, and the blocking member is used to block the drain outlet.

[0010] The second filter basket is provided with a drain port for draining water, and when the second filter basket is filtering, a plugging piece is used to block the drain port. The plugging piece can be set as a plug and is made of corrosion-resistant material.

[0013] Preferably, it further comprises covering members movably arranged on the top of the first funnel member and the second funnel member, respectively, and the covering members are used to cover the first funnel member and the second funnel member respectively.

[0014] After the filtering work is completed, the first funnel member and the second funnel member are covered respectively with a cover member, and the first filter basket and the second filter basket are also covered to prevent dust from entering, so that the first funnel member, the first filter basket, the second funnel member and the second filter basket are kept clean.

[0015] Preferably, it also includes discharge valves respectively installed on the funnel openings.

[0016] The discharge valve can be used to control the opening sizes of the funnel openings of the first funnel member and the second funnel member, thereby controlling the falling flow rate of kerosene, thereby facilitating adjustment of the filtering conditions.

[0017] Preferably, the ends of the funnel opening and the drain outlet are both oblique.

[0018] The oblique mouth facilitates the falling of kerosene and prevents kerosene from hanging on the end of the funnel opening or the drain outlet.

[0019] Preferably, the support seat and the oil storage member are both made of metal, the support seat is provided with a conductive part, the oil storage member is connected to an electrostatic clamp, the electrostatic clamp is used to clamp onto the conductive part, and the support seat is also connected to a ground wire.

[0020] In order to avoid the danger of static electricity during the filtering process, the support seat and the oil storage member are made of metal, and the static electricity is conducted away by using an electrostatic clamp and a grounding wire. Furthermore, the main structures of the first bracket, the second bracket, the first funnel member, the first filter basket, the second funnel member, and the second filter basket are all made of metal.

[0021] Preferably, the first filter basket and the second filter basket are each provided with a handle.

[0022] A handle is provided to facilitate taking out the first filter basket and the second filter basket.

[0023] Preferably, the first bracket and the second bracket are rotatably connected to the support seat respectively.

[0024] The first bracket and the second bracket can be rotated relative to the support seat. When the first filter component or the second filter component needs to be used alone, the first filter component or the second filter component can be rotated to the other side through the first bracket or the second bracket for easy use.

[0025] Compared with the prior art, the utility model has the following beneficial effects:

[0026] The first filter assembly and the second filter assembly are used to filter solid impurities and water from kerosene respectively. After two filtrations under the action of gravity, the kerosene falls into the oil storage component to complete the filtration. The filtration process is relatively efficient and does not require manual intervention, which improves work efficiency and reduces the workload of workers. The first filter assembly and the second filter assembly can be used in any combination, and the filtering method is flexible. Through different combinations, the filtration efficiency and filtration quality can be flexibly controlled. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Kerosene is put into the first filter basket 402, and after filtering, it falls into the first funnel 401, and then passes through the second filter basket 502 and the second funnel 501 in sequence, and finally falls into the oil storage part 6. The first filter basket 402 and the second filter basket 502 are used to increase the filter area and improve the filtering efficiency, and the first funnel 401 and the second funnel 501 are used to gather kerosene so that the kerosene can fall accurately into the next part. Compared with filtering with a filter element, the above arrangement has a much higher filtering efficiency. Furthermore, the first funnel 401 and the second funnel 501 have similar appearances, both of which are a circular ring structure plus a funnel structure, the circular ring structure is located at the top, and the funnel structure is located at the bottom. The appearance of the first filter basket 402 and the second filter basket 502 is also similar to that of the first funnel 401 and the second funnel 501. Specifically, the filter net of the first filter basket 402 is attached with filter cotton by bundling or bonding, and the filter cotton is composed of specially treated polyester-cotton fiber and other synthetic materials, which can filter out solid particle impurities in the oil. The filter net of the second filter basket 502 is attached with a metal wire mesh sprayed with Teflon or other hydrocarbon-philic and hydrophobic substances by bundling or bonding, which can filter out moisture in the oil. Further, the first filter basket 402 and the second filter basket 502 can both use the coalescing filter element replaced by the filter separator as the filter material, saving costs. The first filter basket 402 is movably arranged in the first funnel member 401, which means that the first filter basket 402 and the first funnel member 401 are detachably connected, and the second filter basket 502 and the second funnel member 501 are also detachably connected.

When a hook is used, a ring can be set on the top of the blocking member 503, and the hook hooks the ring to hook out the blocking member 503. After the filtering work is completed, the first funnel member 401 and the second funnel member 501 are covered by the cover member 10, and the first filter basket 402 and the second filter basket 502 are also covered to prevent dust from entering, so that the first funnel member 401, the first filter basket 402, the second funnel member 501 and the second filter basket 502 are kept clean. The discharge valve 11 can control the opening size of the funnel opening 7 of the first funnel member 401 and the second funnel member 501, and then control the falling flow of kerosene, so as to facilitate the adjustment of the filtering situation. The oblique mouth is conducive to the falling of kerosene, and prevents kerosene from hanging on the end of the funnel opening 7 or the drain port 8.

[0042] Furthermore, the inner side walls of the first funnel member 401 and the second funnel member 501 are respectively provided with placement rings, and the first filter basket 402 and the second filter basket 502 are respectively placed on the placement rings.
