[0030] The utility model discloses a convenient to disassemble and assemble double-layer filter core structure. Figures 1-5 The utility model discloses a convenient to disassemble and assemble double-layer filter core structure.
[0031] As Figure 1 , Figure 2 And Figure 3 Indicated in one embodiment, a convenient to disassemble and assemble double-layer filter core structure, including inner core 100, filter assembly 200 and shell 300.
[0032] The inner core 100 is screwed in the cavity of the laser main body 10, and the inner core 100 has a filter channel 110 and a first air inlet hole 120, and the inner core 100 extends to the end of the shell of the laser main body and has a hexagonal hole 130, and the filter channel 110 and the first air inlet hole 120 are communicated with each other.
[0033] The filter assembly 200 is installed in the filter channel 110.
[0034] Referring to Figure 4 The shell 300 is sleeved on the outer wall of the inner core 100, and the shell 300 is fixed in the inner cavity of the laser main body by bolts, and the shell 300 has a second air inlet hole 310 and an air outlet hole 320, and the second air inlet hole 310 and the air outlet hole 320 are both internally threaded holes.
[0035] When the shell 300 and the inner core 100 are fixed in the cavity of the laser main body 10, the shell 300 and the inner core 100 have an airflow channel 330, and the first air inlet hole 120 and the second air inlet hole 310 are communicated with the airflow channel 330.
[0036] It needs to be explained that the dehumidification system in the laser main body 10 is composed of pipe joints 20 / 21 / 22 / 23, pipelines 30 / 31 / 32, an air pump 40 and a double-layer filter element structure. When the filter system is working, the air pump 40 draws out the humid air in the cavity through the pipe joint 20 and the pipeline 30, and then sends the humid air into the filter element device through the pipeline 31 and the pipe joint 21. After passing through the filter material 230 in the double-layer filter element structure, the humid air becomes dry air, and then the dry air returns to the cavity through the pipe joint 22, the pipeline 32 and the pipe joint 23. The pipe joint 20 and the pipe joint 23 are fixed on the cavity of the laser main body 10 and connect the space inside the cavity which needs to be dehumidified. The pipe joint 21 is threadedly connected in the second air inlet hole 310, and the pipe joint 22 is threadedly connected in the air outlet hole 320. The air pump 40 and the double-layer filter element structure are fixed on the cavity of the laser main body 10.
[0037] When the filter assembly 200 is working, the gas enters the filter passage 110 from the second air inlet hole 310 through the air flow passage 330 and the first air inlet hole 120 in sequence, and then leaves from the air outlet hole 320 after being filtered by the filter assembly 200.
[0038] The double-layer filter element structure is convenient to disassemble and assemble. When the inner core 100 is checked, only the old inner core 100 needs to be unscrewed by using a hexagonal wrench to cooperate with the hexagonal hole 130, so that the old inner core 100 can be taken out. When the inner core 100 needs to be replaced, the new inner core 100 can be inserted into the cavity of the laser main body 10. After the new inner core 100 is inserted, the new inner core 100 can be fixed on the cavity of the laser main body 10 by using a hexagonal wrench. The whole replacement process does not involve disassembly and assembly of the pipeline, and the operation is simple and convenient, the replacement efficiency is high, and there is no risk of damaging the pipeline.
[0039] In this embodiment, sealing rings 340 are arranged between the inner core 100 and the laser main body, between the inner core 100 and the outer shell 300, and between the outer shell 300 and the laser main body.
[0040] In this embodiment, guide angles 150 are arranged on the outer shell 300 and the inner core 100, and the guide angles 150 are used to limit the positions of the sealing rings 340.
[0041] In the initial assembly, the inner core 100 is first fixed in the cavity of the laser main body 10 by thread connection, and then the outer shell 300 is inserted into the inner core 100. Then, the outer shell 300 is fixed on the cavity of the laser main body 10. This is to align the guide angles 150 on the outer shell 300 and the cavity of the laser main body 10, so that the compression rates of the two sealing rings 340 on the inner core 100 are uniform in the circumferential direction, and the insertion of the inner core 100 is easy.
[0042] In this embodiment, referring to Figure 5The filter assembly 200 comprises a first partition plate 210 and a second partition plate 220, and a filter material 230 is arranged between the first partition plate 210 and the second partition plate 220.
[0043] It should be noted that the first partition plate 210 and the second partition plate 220 are both provided with air permeable holes, facilitating the circulation of airflow.
[0044] The filter material 230 is arranged in the filter channel 110 of the inner core 100, and the first partition plate 210 and the second partition plate 220 facilitate the limitation of the position of the filter material 230.
[0045] In this embodiment, filter paper 240 is arranged between the first partition plate 210 and the filter material 230 and between the second partition plate 220 and the filter material 230, and the filter paper 240 can prevent the powder of the filter material 230 from leaking out.
[0046] In this embodiment, a third partition plate 250 is further arranged in the filter channel 110, a humidity indicating test paper 280 is arranged between the second partition plate 220 and the third partition plate 250, and the third partition plate 250 is made of transparent acrylic material.
[0047] It should be noted that the third partition plate 250 is provided with air permeable holes, facilitating the circulation of airflow.
[0048] The third partition plate 250 is made of transparent acrylic material, so as to facilitate the observation of the state of the humidity indicating test paper 280. When checking the inner core 100, only the old inner core 100 needs to be unscrewed by using an internal hexagonal wrench, and then the old inner core 100 can be taken out. At this time, whether the filter material 230 has reached the life limit can be determined by observing the discoloration of the humidity indicating test paper 280. If it is judged that the inner core 100 needs to be replaced, a new inner core 100 can be inserted into the cavity of the laser main body 10. After the new inner core 100 is inserted, the new inner core 100 can be fixed on the cavity of the laser main body 10 by using an internal hexagonal wrench. The whole replacement process does not involve the disassembly of the pipeline, is simple and convenient to operate, has high replacement efficiency, and has no risk of damaging the pipeline.
[0049] In this embodiment, the first partition plate 210 is a partition plate with a boss.
[0050] Through the design of the shape of the first partition plate 210, the circulation efficiency of airflow is facilitated to be improved, so that the airflow that needs to be filtered can quickly enter the filter channel 110. At the same time, the filter material 230 is facilitated to be limited in the filter channel 110, so that the filter material 230 does not fall into the first air inlet hole 120 of the inner core 100.
[0051] In this embodiment, a compression spring 260 is fixedly connected between the second partition plate 220 and the third partition plate 250, a recess 140 is arranged on the inner wall of the inner core 100, and an elastic retaining ring 270 is clamped in the recess 140.
[0052] The filter material 230 can be fixed between the first partition 210 and the second partition 220 by the compression spring 260 and the elastic retainer ring 270.
[0053] The technical features of the above-described embodiments can be combined in any manner, and for brevity, not all possible combinations of the technical features in the above-described embodiments are described, but as long as the combinations of the technical features do not contradict each other, they should be considered within the scope of the present disclosure.
