[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 horizontal oil tank that allows for easy replacement of the filter without opening the end cover. Utility Model Content

[0026] This utility model discloses a horizontal oil tank, which includes a tank body 10. A filter device 12 is installed inside the tank body 10. The filter device 12 includes a main filter assembly 1 and a secondary filter assembly 2. The main filter assembly 1 includes a main filter screen 102. The secondary filter assembly 2 includes a secondary filter screen. The secondary filter assembly 2 is fixedly connected to the inner wall of the tank body 10. One side of the secondary filter assembly 2 is provided with a linearly extending groove, the opening of which faces the main filter assembly 1. The side of the main filter assembly 1... The main filter assembly 1 and the secondary filter assembly 2 are slidably embedded in the slide groove, so that they are spliced ​​into a whole, and the main filter screen 102 and the secondary filter screen are parallel to each other; the main filter screen 102 and the secondary filter screen are vertically arranged in the housing 10; the top of the housing 10 has a narrow slit opening, which is located directly above the main filter assembly 1; the upper end of the slide groove has an opening, so that the main filter assembly 1 can be vertically pulled out or inserted into the slide groove through the narrow slit opening; the narrow slit opening is provided with a removable sealing cover.

[0027] Due to the aforementioned structure, 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 becomes clogged, simply open the sealing cover, and the main filter assembly 1 can be vertically pulled out of the oil tank through the narrow slit opening. After replacing the main filter assembly 1, insert the new main filter assembly 1 vertically into the groove on one side of the secondary filter assembly 2 through the narrow slit opening at the top of the oil tank, thus connecting the main filter assembly 1 and the secondary filter assembly 2 together.

[0028] This utility model's horizontal oil tank allows for filter maintenance without removing the end caps or draining the oil, making maintenance more convenient. When the secondary filter becomes clogged, it can be replaced while the equipment is stopped, rather than during operation, making operation more flexible and convenient.

[0029] like Figure 1 As shown in this utility model, the main filter assembly 1 is provided with a secondary filter assembly 2 on both the left and right sides. Both secondary filter assemblies 2 are fixedly connected to the inner wall of the housing 10, that is, the sides of the mounting grooves are all in contact with the inner wall of the housing 10 and can be detachably connected. The left side of the main filter assembly 1 is slidably disposed in the groove of the left secondary filter assembly 2, and the right side is slidably disposed in the groove of the right secondary filter assembly 2. The lower outer edge of the main filter assembly 1 can be in contact with the inner wall of the housing 10.

[0030] 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.

[0031] Furthermore, a handle 3 is provided at the top of the main filter assembly 1. This facilitates the replacement of the main filter assembly 1.

[0032] Furthermore, a sealing cover mounting base 11 is provided at the narrow slit opening at the top of the housing 10; a main filter assembly (1) disassembly port is provided inside the sealing cover mounting base (11) that penetrates the top and bottom of the sealing cover mounting base (11), and the shape of the cross-section of the main filter assembly (1) disassembly port matches the narrow slit opening; the lower end of the sealing cover mounting base 11 is connected to the narrow slit opening, and the upper end is detachably connected to the sealing cover.

[0033] If the top of the housing 10 has an irregular shape, it is inconvenient to install a sealing cover. If a sealing cover mounting base 11 is present, the upper end of the sealing cover mounting base 11 can always be flat, which facilitates the installation of the sealing cover. At the same time, the sealing cover mounting base 11 has a certain height, which can prevent oil from overflowing from the narrow slit opening when the oil level is too high.

[0034] In this utility model, the housing 10 is cylindrical, and the outer edge of the secondary filter assembly 2 is attached to the inner wall of the housing 10; the width of the narrow slit opening is greater than the width of the main filter assembly 1, the central angle corresponding to the arc length of the narrow slit opening is less than 180°, and the projected length of the narrow slit opening in the horizontal direction is greater than the length of the main filter assembly 1.

[0035] If the housing 10 is rectangular, the secondary filter assembly 2 can be completely replaced by a guide rail, and only a rectangular main filter screen 102 needs to be installed in the housing 10. However, when the housing 10 is cylindrical, if the guide rail and the rectangular main filter screen 102 are still used, there will be large gaps on the left and right sides of the rectangle. In this case, the secondary filter assembly 2 will not have this problem. This utility model adopts a structure in which the outer edge of the secondary filter assembly 2 is tightly fitted to the inner wall of the cylinder, which can effectively avoid the generation of such gaps and ensure that all oil flows through the filter device 12.

[0036] The central angle corresponding to the arc length of the narrow slit opening is less than 180°, which can ensure the strength of the tank 10 and also keep the oil at a high level, preventing the oil from overflowing from the narrow slit opening.

[0037] 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 first main frame 101 and the second main frame 103 are slidably disposed within the groove of the right side auxiliary filter assembly 2. The first main frame 101, the second main frame 103, and the main filter screen 102 are fixed together by bolts.

[0038] 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.

[0039] 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 fits against the inner wall of the housing 10; 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.

[0040] 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.

[0041] Furthermore, an angle steel 206 is fixedly connected 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.

[0042] like Figure 6 As shown, there are two main filter components 1; angle steels 206 are fixed to the left and right sides of the secondary frame 203 respectively to form two independent sliding grooves; the two main filter components 1 are respectively embedded in the corresponding sliding grooves.

[0043] The presence of two main filter components 1 ensures that when one is extracted, the other is still working.

[0044] Furthermore, the bottom of the sub-frame 203 of the left sub-filter assembly 2 and the right sub-filter assembly 2 is connected by a connecting plate 4, and the outer edge of the connecting plate 4 is attached to the inner wall of the housing 10.

[0045] 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.

[0046] 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.
