Detailed Description
The invention will be further described with reference to the following specific embodiments:
referring to fig. 1 to 5, a detachable natural gas filter comprises a housing 1, a supporting sleeve 2, a filter element 3, a filter core shaft 4, an air inlet pipe 51 and an air outlet pipe 52, wherein a filter cavity 11 is formed in the housing 1, the supporting sleeve 2 is arranged at the center of the filter cavity 11, the air inlet pipe 51 is connected with the filter cavity 11, the air outlet pipe 52 is connected with the supporting sleeve 2, the filter core shaft 4 comprises a first rotating shaft 41 and a second rotating shaft 42 which are arranged up and down, a connecting groove 411 is formed at the bottom surface of the first rotating shaft 41, an internal thread is formed in the connecting groove 411, a connecting boss 421 is formed at the top end of the second rotating shaft 42, an external thread is formed on the outer side wall of the connecting boss 421 for being in threaded connection with the connecting groove 411, the second rotating shaft 42 is vertically and fixedly arranged on the supporting sleeve 2, the filter element 3 is arranged on the top surface of the supporting sleeve 2 and is downwards communicated with the supporting sleeve 2, the filter element 3 is sleeved on the filter core shaft 4, wherein a plurality of impellers 31 distributed annularly, the plurality of impellers 31 extend along the length direction of the filter element 3, and the plurality of impellers 31 are used for driving the filter element 3 to rotate on the filter core shaft 4 through gas flowing liquid distribution.
The top cover 12 is detachably mounted on the top surface of the housing 1, a limiting block 412 is formed at the top end of the first rotating shaft 41 and used for supporting the top cover 12 upwards, a limiting boss 413 is formed on the top surface of the limiting block 412, the limiting boss 413 upwards penetrates through the top cover 12, an external thread is formed on the limiting boss 413, and the nut 43 and the limiting block 412 are clamped and fixed on the top cover 12 up and down by screwing the nut 43 downwards onto the limiting boss 413.
