Description
Technical Field
[0001] This utility model relates to the field of filter screens, and in particular to an assembled filter screen structure. Background Technology
[0002] In horizontal cylindrical oil tanks, integral circular filters are currently commonly used; the filters are often vertically installed and fixed in the oil tank with bolts.
[0003] When the filter becomes clogged, all the oil must be drained and the end cap removed before it can be replaced, which is troublesome and time-consuming.
[0004] If you try to open the top of the fuel tank to pull out the filter directly, but the filter is fixed in the fuel tank with bolts and has no separable structure, even if the opening is large enough, the filter still cannot be removed from its fixed position. You can only open the end cover and manually enter the fuel tank to remove the filter.
[0005] Therefore, it is particularly necessary to provide a new filter structure that allows the oil tank to be removed without opening the end cap. Utility Model Content
[0006] The purpose of this utility model is to provide a modular filter structure that addresses the above-mentioned problems, allowing the filter to be easily removed and replaced from the oil tank without opening the end cap.
[0007] The technical solution adopted in this utility model is as follows: A modular filter structure includes a main filter assembly and a secondary filter assembly; The main filter assembly is equipped with a main filter screen; The secondary filter assembly is equipped with a secondary filter screen; The secondary filter assembly has a linearly extending groove on its side, with the groove opening facing the main filter assembly. The side of the main filter assembly is slidably embedded in the groove, so that the main filter assembly and the secondary filter assembly are spliced into a whole, and the main filter screen and the secondary filter screen are parallel to each other. In the extending direction of the chute, at least one end of the chute has an opening, allowing the main filter assembly to slide out or be inserted from the opening end along the extending direction of the chute.
[0008] Furthermore, secondary filter components are provided on both the left and right sides of the main filter component; the left side of the main filter component is slidably disposed in the groove of the left secondary filter component, and the right side is slidably disposed in the groove of the right secondary filter component.
[0009] Furthermore, the main filter assembly includes a main frame one, a main frame two, and a main filter screen; The main filter screen is located between main frame one and main frame two; The left sides of the main frame one and the main frame two are slidably disposed in the groove of the left auxiliary filter component; The right sides of the main frame one and the main frame two are slidably disposed in the groove of the right side auxiliary filter component.
[0010] Furthermore, the main frame one, the main frame two, and the main filter screen are fixed together by bolts.
[0011] Furthermore, the secondary filter assembly includes a secondary frame one, a secondary frame two, a secondary frame three, and a secondary filter screen; The secondary filter screen includes a first secondary filter screen and a second secondary filter screen; The first filter screen is located between the first sub-frame and the second sub-frame; The second secondary filter is located between secondary frame two and secondary frame three; The outer edge of the second sub-frame protrudes outward, and the sliding groove is provided on the second sub-frame.
[0012] Furthermore, the first filter screen, the first sub-frame, and the second sub-frame are connected together by bolts; The second filter screen, the second sub-frame, and the third sub-frame are connected together by bolts.
[0013] Furthermore, an angle steel is fixed to the side of the second sub-frame, and the angle steel and the side of the second sub-frame together form the U-shaped groove structure of the sliding groove.
[0014] Furthermore, the number of main filter components is two; Angle steel is fixed to the left and right sides of the second sub-frame to form two independent sliding grooves; The two main filter components are respectively embedded in their corresponding grooves.
[0015] Furthermore, the main filter assembly and the secondary filter assembly are arranged vertically, and the top of the chute is open; The bottom of the secondary frame of the left and right secondary filter components is connected by a connecting plate.
[0016] Furthermore, a handle is provided at the top of the main filter assembly.
[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: In this invention, when the main filter screen is clogged, a narrow slit opening is made at the top of the oil tank, and the main filter assembly can be pulled vertically upwards out of the oil tank. After replacing the main filter assembly, the new main filter assembly is inserted vertically into the slide groove from the top of the oil tank, so that the main filter assembly and the auxiliary filter assembly are spliced together.
[0018] The filter structure of this invention allows for filter maintenance without disassembling the end cap and without draining the oil, making maintenance more convenient. When the secondary filter becomes clogged, it can be replaced when the equipment is stopped, rather than during operation, making operation more flexible and convenient. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0026] This utility model discloses an assembled filter structure, including a main filter assembly 1 and a secondary filter assembly 2; the main filter assembly 1 is provided with a main filter 102; the secondary filter assembly 2 is provided with a secondary filter; the side of the secondary filter assembly 2 is provided with a straight-extending groove, the opening of the groove facing the main filter assembly 1; the side of the main filter assembly 1 is slidably embedded in the groove, so that the main filter assembly 1 and the secondary filter assembly 2 are spliced into a whole, and the main filter 102 and the secondary filter are parallel to each other; in the extension direction of the groove, at least one end of the groove has an opening, so that the main filter assembly 1 can slide out or be inserted from the opening end along the extension direction of the groove.
[0027] like Figure 1 As shown, when the filter structure 12 of this utility model is installed in the horizontal cylindrical oil tank 10, the main filter assembly 1 and the auxiliary filter assembly 2 are both vertically arranged, and the upper end of the slide groove is open. The auxiliary filter assembly 2 is fixed inside the oil tank, while the main filter assembly 1 can slide up and down.
[0028] In actual use, the area of the main filter 102 is larger than that of the secondary filter. Most impurities are intercepted by the main filter 102, making it more prone to clogging. When the main filter 102 is clogged, a narrow slit opening 11 is made at the top of the fuel tank, allowing the main filter assembly 1 to be vertically pulled out of the tank. After replacing the main filter assembly 1, the new main filter assembly 1 is then vertically inserted into the groove on one side of the secondary filter assembly 2 from the top of the fuel tank, thus connecting the main filter assembly 1 and the secondary filter assembly 2 together.
[0029] The filter structure 12 of this utility model allows for filter maintenance without disassembling the end cap and without draining the oil, making maintenance more convenient. When the secondary filter becomes clogged, it can be replaced when the equipment is stopped, rather than during operation, making operation more flexible and convenient.
[0030] like Figure 2 As shown in the present invention, fixed filter components are provided on both the left and right sides of the movable filter component; the left side of the movable filter component is slidably disposed in the groove of the left fixed filter component, and the right side is slidably disposed in the groove of the right fixed filter component.
[0031] In the above structure, the double-sided sliding groove design makes the main filter component 1 subjected to balanced force, avoiding jamming or tilting caused by sliding on one side.
[0032] Furthermore, the main filter assembly 1 includes a main frame 101, a main frame 2 103, and a main filter screen 102; the main filter screen 102 is located between the main frame 101 and the main frame 2 103; the left sides of the main frame 101 and the main frame 2 103 are slidably disposed in the groove of the left auxiliary filter assembly 2; the right sides of the main frame 101 and the main frame 2 103 are slidably disposed in the groove of the right auxiliary filter assembly 2. The main frame 101, the main frame 2 103, and the main filter screen 102 are fixed together by bolts.
[0033] In this invention, the main filter 102 is clamped by a double-layer frame, which is stronger than a single-layer frame and can prevent the main filter assembly 1 from being deformed by impact during operation.
[0034] Furthermore, the secondary filter assembly 2 includes a secondary frame 1 201, a secondary frame 203, a secondary frame 3 205, and a secondary filter screen; the secondary filter screen includes a first secondary filter screen 202 and a second secondary filter screen 204; the first secondary filter screen 202 is located between the secondary frame 1 201 and the secondary frame 203. The second auxiliary filter 204 is located between the second auxiliary frame 203 and the third auxiliary frame 205; the outer edge of the second auxiliary frame 203 protrudes outward, and the sliding groove is provided on the second auxiliary frame 203. The first auxiliary filter 202, the first auxiliary frame 201, and the second auxiliary frame 203 are connected together by bolts; the second auxiliary filter 204, the second auxiliary frame 203, and the third auxiliary frame 205 are connected together by bolts.
[0035] In the above structure, the outer edge of the second sub-frame 203 protrudes outward, which facilitates the installation of the sliding groove. Simultaneously, the outward protrusion of the outer edge of the second sub-frame 203 also facilitates connection with the inner wall of the fuel tank. The outer contour shape of the second sub-frame 203 must match the shape of the inner wall of the fuel tank.
[0036] Furthermore, an angle steel 206 is fixed to the side of the second sub-frame 203, and the angle steel 206 and the side of the second sub-frame 203 form the sliding groove with a U-shaped groove structure.
[0037] like Figure 6 As shown, there are two movable filter components; angle steels 206 are fixed to the left and right sides of the sub-frame 203 respectively to form two independent sliding grooves; the two movable filter components are respectively embedded in the corresponding sliding grooves.
[0038] The presence of two main filter components 1 ensures that when one is extracted, the other is still working.
[0039] like Figure 4 As shown, the movable filter assembly and the fixed filter assembly are vertically arranged, and the top of the slide is open; the bottom of the sub-frame 203 of the left fixed filter assembly and the right fixed filter assembly is connected by the connecting plate 4.
[0040] The presence of the connecting plate 4 ensures that the two secondary filter components 2 are installed more stably, and can sandwich the main filter component 1 between the two secondary filter components 2, ensuring the stable operation of the main filter component 1.
[0041] The main filter assembly 1 is provided with a handle 3 at its upper end, which makes it easy to pull the main filter assembly 1 out from the top of the oil tank.
[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
