Description

Technical Field

[0001] The utility model relates to the technical field of pipeline liquid filters, in particular to an easily disassembled pipeline liquid filter. Background Art

[0002] Pipeline liquid filter is an indispensable device on the pipeline for conveying medium. It is usually installed at the inlet end of pressure reducing valve, pressure relief valve, water level valve or other equipment. Some of the conveyed liquid will contain certain impurities. These impurities are easy to accumulate in the valve when water passes through the valve. Long-term accumulation will easily cause the impurities in the valve to be blocked in the valve, which is easy to increase the hydraulic pressure at the valve. The increase in water pressure will easily cause the valve to be damaged due to the increase in water pressure. Therefore, pipeline liquid filter is mainly used to eliminate impurities in the medium to protect the normal use of valves and equipment.

[0003] In the prior art, a filter screen is installed in a pipeline liquid filter to filter impurities. The filter screen is mainly installed in the pipeline, and the filter screen is installed at the vertical end, and the outlet is blocked by the filter screen, while the outlet of the liquid pipeline filter is not blocked by the filter screen, so that the liquid can be filtered through the filter screen when entering, and the impurities are sunk in the vertical end of the liquid pipeline filter. When installing the filter screen, the bottom of the filter screen needs to be filtered by bolts, and then the top of the pipeline liquid filter is blocked by a flange, and the top of the filter screen is fixed by the flange to ensure the stability of the filter screen when it is impacted by liquid. This installation method takes a long time to use, because the filter screen needs to be disassembled and cleaned after filtering a certain amount of impurities, so the disassembly and installation of the bolts takes a lot of time, which affects the progress of liquid filtration. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an easily disassembled pipeline liquid filter so as to solve the technical problems mentioned in the above background technology.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A pipeline liquid filter that is easy to disassemble comprises a main through-tube, wherein the main through-tube is composed of a transverse section and a vertical section, and the main through-tube is arranged in a cross shape, wherein the bottom end of the vertical section is closed, and the transverse section is sequentially an inlet end and an outlet end from one end to the other end, and a filter screen is installed on one side of the vertical section close to the outlet end of the transverse section through a limiter, and the filter screen is arranged in an arc shape, and the outer side wall of the filter screen fits the inner side wall of the vertical section.

[0007] In a preferred example, the utility model can be further configured as follows: the limiting member includes an arcuate groove, the arcuate groove is opened at the bottom of the vertical section, the bottom end of the filter is embedded in the arcuate groove, and the bottom end of the filter is slidably connected to the arcuate groove.

[0008] In a preferred example, the utility model can be further configured as follows: an arc-shaped bar is slidably connected in the arc-shaped groove, and two ends of the arc-shaped bar are respectively fitted with two sides of the filter screen.

[0009] In a preferred example, the utility model can be further configured as follows: an arc-shaped limit plate is installed on the top of the inner wall of the vertical section, the bottom side of the arc-shaped limit plate is in contact with the filter screen, and a first baffle is connected to one end of the arc-shaped limit plate close to the inlet end of the horizontal section.

[0010] In a preferred example, the utility model can be further configured as follows: a sealing flange is installed at the top of the vertical section, a limiting disk is fixedly connected to the bottom side of the sealing flange, an outer peripheral wall of the limiting disk is fitted with the inner wall of the filter screen, a second baffle is fixedly connected to the bottom side of the sealing flange, and an edge of the second baffle is fitted with a side of the filter screen away from the first baffle.

[0011] In summary, the present invention includes at least one of the following beneficial technical effects:

[0012] 1. This is an easily disassembled pipeline liquid filter. When in use, after removing the flange, the vertical section is released, and then the filter screen can be pushed to slide between the arc-shaped limit plate and the arc-shaped groove. After the top of the filter screen is separated from the limit of the arc-shaped limit plate, the vertical section can be directly pulled out, thereby achieving a quick disassembly effect.

[0013] 2. This is an easily disassembled pipeline liquid filter. The arc groove is set so that the bottom end of the filter can be inserted into the arc groove when the filter is placed. Then the bottom end of the filter will be limited by the arc groove to avoid scouring during liquid transportation and causing the filter to tilt, thereby improving the stability of the filter when in use.

[0014] 3. This is an easily disassembled pipeline liquid filter, in which the arc-shaped bar can slide in the arc-shaped groove. After the filter screen is inserted into the arc-shaped groove, the two ends of the arc-shaped bar will respectively fit with the two sides of the filter screen, so that the arc-shaped bar cooperates with the filter screen to completely block the arc-shaped groove, preventing the filtered impurities from falling into the arc-shaped groove, which increases the difficulty of cleaning.

[0015] 4. This is an easily disassembled pipeline liquid filter. When the filter screen rotates to the outlet end of the transverse section, the top of the filter screen will fit with the bottom side of the arc-shaped limit piece, thereby limiting the filter screen by the bottom side of the arc-shaped limit piece. The first baffle is used to block the filter screen when it rotates, which is convenient for positioning the filter screen when it rotates and can quickly block the outlet end of the transverse section to achieve a quick installation effect.

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] Example:

[0023] Reference Figure 1-Figure 3 The utility model discloses an easily disassembled pipeline liquid filter, comprising a main through-tube 1, wherein the main through-tube 1 is composed of a transverse section 2 and a vertical section 3, and the main through-tube 1 is arranged in a cross shape, wherein the bottom end of the vertical section 3 is closed, and the transverse section 2 is sequentially an inlet end and an outlet end from one end to the other end, and a filter screen 5 is installed on one side of the vertical section 3 close to the outlet end of the transverse section 2 through a limiter 4, and the filter screen 5 is arranged in an arc shape, and the outer side wall of the filter screen 5 is in contact with the inner side wall of the vertical section 3.

[0024] In this embodiment, when installing the filter 5, the filter 5 is placed downward from the vertical section 3 in the main pipe 1, and then the filter 5 is rotated until the outlet end of the transverse section 2 is blocked. At the same time, the limiter 4 is used to limit the vertical section 3, and when disassembling, the limit of the filter 5 by the limiter 4 is released, and then the filter 5 can be removed by rotating it, thereby achieving the purpose of quick disassembly.

[0025] In a further preferred embodiment of the present invention, Figure 1-3 As shown, the limiting member 4 includes an arc groove 6, which is opened at the bottom of the vertical section 3, the bottom end of the filter screen 5 is embedded in the arc groove 6, and the bottom end of the filter screen 5 is slidably connected to the arc groove 6.

[0026] In this embodiment, the arc groove 6 is set so that the bottom end of the filter 5 can be inserted into the arc groove 6 when the filter 5 is placed. Then the bottom end of the filter 5 will be limited by the arc groove 6 to avoid the filter 5 from tilting due to scouring during liquid transportation, thereby improving the stability of the filter 5 during use.

[0027] In a further preferred embodiment of the present invention, Figure 1-3 As shown, an arc-shaped bar 7 is slidably connected in the arc-shaped groove 6 , and two ends of the arc-shaped bar 7 are respectively in contact with two sides of the filter screen 5 .

[0028] In this embodiment, the arc strip 7 provided therein can slide in the arc groove 6. After the filter screen 5 is inserted into the arc groove 6, the two ends of the arc strip 7 will respectively fit with the two sides of the filter screen 5, so that the arc strip 7 cooperates with the filter screen 5 to completely block the arc groove 6, preventing the filtered impurities from falling into the arc groove 6, thereby increasing the difficulty of cleaning.

[0029] In a further preferred embodiment of the present invention, Figure 1-3 As shown, an arc-shaped limit plate 8 is installed on the top of the inner wall of the vertical section 3, the bottom side of the arc-shaped limit plate 8 is in contact with the filter screen 5, and the end of the arc-shaped limit plate 8 close to the inlet end of the horizontal section 2 is connected to a first baffle 9.

[0030] In this embodiment, when the filter screen 5 rotates to the outlet end of the transverse section 2, the top of the filter screen 5 will fit with the bottom side of the arc-shaped limit plate 8, thereby limiting the filter screen 5 through the bottom side of the arc-shaped limit plate 8, and the first baffle 9 is used to block the filter screen 5 when it rotates, which is convenient for positioning the filter screen 5 when it rotates and can quickly block the outlet end of the transverse section 2 to achieve a quick installation effect.

[0031] In a further preferred embodiment of the present invention, Figure 1-3As shown, a sealing flange 10 is installed at the top of the vertical section 3, and a limiting plate 11 is fixedly connected to the bottom side of the sealing flange 10. The outer peripheral wall of the limiting plate 11 fits with the inner wall of the filter screen 5. A second baffle 12 is fixedly connected to the bottom side of the sealing flange 10, and the side of the second baffle 12 fits with the side of the filter screen 5 away from the first baffle 9.

[0032] In this embodiment, the sealing flange 10 is used to seal the top of the vertical section 3. At the same time, the outer wall of the limiting plate 11 will fit the top of the inner wall of the filter 5, so that the top of the filter 5 is limited by the limiting plate 11 to avoid tilting due to the erosion of liquid, thereby further improving the stability of the filter 5 during use. The second baffle 12 is used to position the other side of the filter 5, so that both sides of the filter 5 are restricted to avoid the filter 5 being flushed by liquid after installation, causing the position of the filter 5 to move and affect the filtration.

[0033] In this embodiment, when the filter 5 is disassembled, the second baffle 12 will be removed at the same time as the flange is removed. At this time, the filter 5 loses the limit on one side, and the slidable filter 5 performs a circular motion in the arc groove 6. When the filter 5 rotates, it can be pulled out after being disengaged from the limit of the arc limit plate 8, thereby achieving the effect of quick disassembly.

[0034] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
