Detailed Description
The present invention will be further explained below.
In this embodiment, as shown in fig. 1 and fig. 2, a filter convenient to renew cartridge more, including last casing 1 and lower casing 2, casing 2 is the tubular shape down, and this lower casing 2 is the hollow column body that both ends all do not seal about and promptly, lower casing 2 the upper end with go up casing 1's bottom through welded mode fixed connection, lower casing 2's lower extreme can be dismantled through bolted connection's mode and be connected with the ring flange 3, and be provided with drain valve 6 on the ring flange 3, go up casing 1, form filter chamber 8 between casing 2 and the ring flange 3 down, go up casing 1's the left and right sides and seted up inhalant canal 10 and exhalant canal 11 respectively, inhalant canal 10 and exhalant canal 11 all with filter chamber 8 intercommunication, just still be connected with filter core 7 on exhalant canal 11, filter core 7 is the cylindric, and this filter core 7 is the column body that the lower extreme seals promptly, and filter core 7 wholly is located filter chamber 8, the upper end cover of filter core 7 is established on exhalant canal 11, and the exhalant canal 7's inner wall and be equipped with exhalant canal 11 between the inner wall and exhalant canal 11, say that the O type sealing washer 9, just also the filter core 7 is closely laminated simultaneously, and the filter core 7 is located filter core 10 one side, and the inhalant canal is closely laminated and the filter core 7, and the filter core 7 is located filter core 10 is located one end and is closely.
Specifically, the flange 3 is provided with a fixing groove 12 adapted to the lower end of the filter element 7, that is, the lower end of the filter element 7 can be engaged with the fixing groove 12, and the filter element 7 is fixed by restricting the movement of the upper and lower ends of the filter element 7 to prevent the movement of the filter element 7.
