Description

Technical Field

[0001] The present application relates to the technical field of filter elements, and in particular to a novel deacidification and oil sludge removal filter element. Background Art

[0002] New mechanical industrial oil is generally weakly alkaline, but after long-term use, it becomes an acidic liquid. Mechanical equipment cannot use oxidized acidic oil for a long time. On the one hand, it will corrode the inner wall of the mechanical equipment, making the mechanical equipment more fragile; on the other hand, in the early stage of the formation of acidic liquid, the impurities formed by corroding the inner wall of the mechanical equipment will reduce the lubrication performance of the oil and weaken the running speed of the machine.

[0003] Traditional filter elements have relatively simple functions. To achieve the two functions of deacidification and sludge removal, one deacidification filter element and another sludge removal filter element need to be connected in series in the same pipeline. The initial pipeline layout is rather cumbersome and takes a long time. In addition, the oil runs in the pipeline for a long time during the filtration process, which not only reduces efficiency but also increases fuel consumption. Utility Model Content

[0004] In order to simplify the filtration process, improve the filtration efficiency, and reduce the oil consumption during the oil filtration process, the present application provides a new type of deacidification and oil sludge removal filter element.

[0005] A novel deacidification and oil sludge removal filter element, comprising:

[0006] A cylinder, wherein the interior of the cylinder is a hollow structure and one end of the cylinder has an oil inlet, and the side wall of the cylinder is a mesh plate structure, and dense meshes form an oil outlet;

The deacidification filter layer is cylindrical, hollow inside, and open at least at one end. The oil inlet is connected to the open end of the deacidification filter layer.

[0008] The oil sludge removal filter element layer is located in the oil filter space;

[0009] The oil introduced from the oil inlet passes through the deacidification filter layer and the sludge removal filter layer in sequence, and is finally discharged from the oil outlet.

[0010] By adopting the above technical scheme, the contaminated oil to be filtered is injected from the oil inlet. When passing through the deacidification filter element layer, a chemical reaction occurs between the two to neutralize the acidic substances in the oil, thereby achieving the effect of deacidification. At this time, there is still sludge in the oil caused by corrosion of the machinery and adsorption of air. The deacidification filter element layer has a penetration effect. The infiltrated oil will penetrate into the oil filter space between the deacidification filter element layer and the outer shell according to the pressure of the oil injected from the rear. In this process, the sludge removal filter element layer intercepts the sludge, and the filtered oil will be discharged through the oil outlet on the outer shell. The overall operation path is short and the filtration process is simple, which greatly improves the filtration efficiency and reduces the fuel consumption in the oil filtration process.

[0013] Preferably, a plurality of conductive needles are fixedly connected to the plate surfaces on the opposite sides of the upper cover and the lower cover, respectively, and the conductive needles are inserted into the oil sludge removal filter element layer.

[0014] By adopting the above technical solution, on the one hand, it can play a role in positioning, and on the other hand, it can lead out static electricity through the conductive needle to prevent static electricity from damaging the filter material.

[0015] Preferably, a handle is fixedly connected to a side of the upper cover away from the conductive needle.

[0016] By adopting the above technical solution, it is convenient for staff to operate according to needs.

The conductive needle is fixed to the inner wall of the annular base plate, and one end of the sludge removal filter layer is against the annular base plate, and the other end is against the inner wall of the upper cover.

[0018] Preferably, it also includes an upper end cover and a lower end cover for limiting at both ends of the deacidification filter core layer, the upper end cover and the lower end cover both have a U-shaped limiting groove, and the two ends of the deacidification filter core layer are located in the U-shaped limiting groove, the upper end cover is pressed against the inner wall of the upper cover, and the lower end cover is located in the installation opening enclosed by the inner ring plate and is fixed to the inner ring plate by gluing, and the oil inlet is arranged in the middle of the lower end cover and is connected to the interior of the deacidification filter core layer.

[0019] Preferably, a pressing portion is fixedly connected to the inner wall of the upper cover, and a plurality of annular grooves are processed on the pressing surface of the pressing portion.

[0020] Preferably, a cork rubber pad is further provided between the pressing portion and the upper end cover.

[0021] The above technical solution is mainly used to improve the sealing between the pressing part and the upper end cover.

[0022] Preferably, the deacidification filter layer is a filter layer made of dry ion exchange resin.

[0023] The above technical solution is mainly used to filter out acidic substances in oil.

[0024] Preferably, the oil sludge removal filter element layer is a filter element layer made of glass fiber material.

[0025] By adopting the above technical solution, it is mainly used to filter out sludge in oil.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-6This application is described in further detail.

[0035] The present application discloses a novel deacidification and degreasing sludge filter element. Figure 1 The deacidification and degreasing filter element comprises a shell 1 which is hollow inside and open at both ends, an upper cover 2 installed at one end of the shell 1, and a lower cover 3 installed at the other end of the shell 1, and a cylinder is formed between the upper cover 2, the shell 1 and the lower cover 3. The upper cover 2 and the lower cover 3 can be connected to the shell 1 by RF flange, threaded connection or bolt connection. The specific connection method is not shown in the figure. On the one hand, it is used to protect the internal filter material, and on the other hand, it is easy to disassemble and replace the filter material.

[0036] Reference Figure 1 , Figure 2 and Figure 3 A pair of handles 21 are fixedly connected to the side of the upper cover 2 away from the outer shell 1, which is convenient for the staff to operate according to needs. A pressing portion 22 is fixedly connected to the inner wall of the upper cover 2 close to the outer shell 1. The pressing portion 22 is annular. When the upper cover 2 is installed on the outer shell 1, the pressing portion 22 extends into the outer shell 1. A plurality of annular grooves are processed on the pressing surface of the pressing portion 22, that is, the side away from the handle 21.

[0037] One end of the housing 1 on which the lower cover 3 is mounted has an oil inlet 71 . The housing 1 is a mesh plate structure, and dense meshes form an oil outlet 11 .

[0038] Reference Figure 4 The lower cover 3 includes an annular bottom plate 31, an inner ring plate 32 formed on the inner circle of the annular bottom plate 31, and an outer ring plate 33 formed on the outer circle of the annular bottom plate 31. A mounting groove with a U-shaped cross-section is formed between the three, and the inner ring plate 32 itself is enclosed into a mounting opening. A gasket is fixedly connected to the side of the annular bottom plate 31 away from the outer shell 1.

[0039] Reference Figure 2 and Figure 5 The interior of the cylinder is provided with a deacidification filter layer 4, an oil sludge removal filter layer 5, an upper end cover 6 and a lower end cover 7; the deacidification filter layer 4 is made of dry ion exchange resin. When the oil passes through the deacidification filter layer 4, a chemical reaction occurs between the two to neutralize the acidic substances in the oil, thereby playing a role in deacidification. The deacidification filter layer 4 is a cylindrical structure, and the upper end cover 6 and the lower end cover 7 are respectively located at the two ends of the deacidification filter layer 4, and are mainly used to limit and fix the deacidification filter layer 4.

[0040] The upper end cover 6 and the lower end cover 7 have the same structure, both of which include an annular cover plate, an inner limit plate fixed to the inner side of the annular cover plate, and an outer limit plate fixed to the outer side of the annular cover plate, and a U-shaped limit groove structure with a U-shaped cross-section is formed between the three. The two ends of the deacidification filter element layer 4 are located in the U-shaped limit groove, and the inner limit plate of the lower end cover 7 is enclosed to form an oil inlet 71, which is connected to the interior of the deacidification filter element layer 4. During installation, the upper end cover 6 is pressed against the pressing part 22, and the lower end cover 7 is located in the installation port enclosed by the inner ring plate 32 and is fixed to the inner ring plate 32 by glue injection, so that an oil filtering space is formed between the deacidification filter element layer 4 and the outer shell 1.

[0041] Reference Figure 2 and Figure 6 In order to further ensure the sealing of the structure, a cork rubber pad 8 is arranged between the pressing part 22 and the upper end cover 6. Since a plurality of annular grooves are processed on the pressing part 22, a plurality of convex ridges are formed between adjacent annular grooves. Therefore, when the pressing part 22 is pressed on the cork rubber pad 8, the convex ridges will sink into the cork rubber pad 8, forming a multi-channel interception structure, which greatly improves the sealing.

[0042] Reference Figure 2 , Figure 3 and Figure 4 The de-oiling sludge filter layer 5 is made of glass fiber material and is located in the oil filtering space between the deacidification filter layer 4 and the outer shell 1, with one end against the annular bottom plate 31 and the other end against the inner wall of the upper cover 2. When the deacidified oil passes through the de-oiling sludge filter layer 5, the sludge is intercepted and the clean oil is discharged through the oil outlet 11. Since the filter material will generate static electricity during the filtration process, and the static electricity will destroy the filter material and affect the filtration efficiency, in order to solve this technical problem, a plurality of conductive needles 9 are fixedly connected to the inner top wall of the upper cover 2, and a plurality of conductive needles 9 are fixedly connected to the inner wall of the annular bottom plate 31 of the lower cover 3. All conductive needles 9 are inserted into the de-oiling sludge filter layer 5. On the one hand, they can play a positioning role, and on the other hand, the static electricity can be discharged through the conductive needles 9.

[0043] The implementation principle of the embodiment of the present application is: the contaminated oil to be filtered is injected from the oil inlet 71, and when passing through the deacidification filter element layer 4, a chemical reaction occurs between the two, neutralizing the acidic substances in the oil, thereby achieving the effect of deacidification. At this time, there is still sludge in the oil caused by corrosion of the machinery and adsorption of air. The deacidification filter element layer 4 has a penetration effect. The infiltrated oil will penetrate into the oil filtering space between the deacidification filter element layer 4 and the outer shell 1 according to the pressure of the oil injected from the rear. In this process, the sludge removal filter element layer 5 intercepts the sludge, and the filtered oil will be discharged through the oil outlet 11 on the outer shell 1. The overall operation path is short and the filtration process is simple, which greatly improves the filtration efficiency and reduces the oil consumption during the oil filtration process.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
