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.

Specifically, the upper shell 1 is fixedly connected with two connecting flanges 5 for externally connecting pipelines, and the two connecting flanges 5 are respectively communicated with a water inlet channel 10 and a water outlet channel 11.

Specifically, the upper housing 1 is provided with an exhaust passage 14 and a sewage discharge passage 13, the exhaust passage 14 is communicated with the water outlet passage 11, the sewage discharge passage 13 is communicated with the water inlet passage 10, and the exhaust passage 14 and the sewage discharge passage 13 are both provided with a cock 15.

Specifically, the outer wall both sides of casing 2 are equipped with fixed plate 4 down, through the centre gripping of two fixed plate 4, the stability of casing 2 under further improvement.

The working principle is as follows:

water inlet channel 10 is connected with external water supply pipeline through flange 5, and water outlet channel 11 is connected with external outlet conduit through flange 5, and water supply pipeline will need to be filtered water and send into filtration cavity 8 through water inlet channel 10 to filter it through filter core 7, water after the filtration flows into outlet conduit from water outlet channel 11, and drain valve 6 is in the off-state this moment of course, avoids filtering water and flows out from drain valve 6 and filters cavity 8.

When needing to overhaul and change filter core 7, at first close external inhalant canal 10 and exhalant canal 11, then screw down cock 15 on exhaust passage 14 and the blowdown passageway 13, make the pressure in the seal chamber be in safe range through exhaust passage 14 and blowdown passageway 13, then take off ring flange 3 from casing 2 down, alright twitch filter core 7 this moment, extract filter core 7 and overhaul or change, impurity in the filter chamber 8 also falls out from the lower extreme of casing 2 down simultaneously, also can clear up filter chamber 8 through the opening of casing 2 lower extreme down this moment.

The principle and the implementation of the present invention are explained by applying specific examples, and the above description of the embodiments is only used to help understand the method and the core idea of the present invention; while the invention has been described in terms of specific embodiments and applications, it will be apparent to those skilled in the art that numerous variations and modifications can be made without departing from the spirit and scope of the invention as defined in the appended claims.
