1 is a view schematically showing a conventional filter housing. 1, the conventional filter housing includes a main body 10, lids 20 and 25 for opening and closing the main body 10, and a filter 30 accommodated in the main body 10.

The main body 10 is provided with an empty space therein so that the filter 30 is accommodated therein, is elongated in the longitudinal direction, and both longitudinal ends thereof are opened.

The lids 20 and 25 open and close both open ends of the main body 10 and include a first lid 20 for opening and closing one end of the main body 10 and a second lid 20 for opening and closing the other end of the main body 10. [ And a cover (25). The first lid 20 and the second lid 25 are formed with an inflow portion 22 and an auxiliary inflow portion 26 so that external fluid can flow through the inflow portion 22 or the auxiliary inflow portion 26 to the main body 10).

The filter 30 is accommodated in the main body 10 and is formed long along the longitudinal direction of the main body 10. A through passage 32 is formed through the filter 30 in the longitudinal direction of the filter 30, and both ends of the through passage 32 are closed. These filters 30 may be constituted by one filter, or a plurality of filters 30 may be arranged in parallel. In the case where the plurality of filters 30 are formed, the through channels 32 of the adjacent filters 30 are configured to communicate with each other by the connecting portions 35. One end of the fluid guide portion 36 is coupled to the through passage 32 of the filter 30 facing the second cover 25 and the other end of the fluid guide portion 36 is connected to the through hole 32 of the second cover 25 And is connected to the discharge port 28. The fluid such as the contaminated water or the cleaning liquid which is received into the main body 10 through the inlet 22 is cleanly filtered by the filter 30 and then passes through the through passage 32 of the filter 30, And is discharged along the discharge port 36 to the discharge port 28.

The first body flange 10a and the second body flange 10b are formed at one end and the other end of the body 10, respectively. A first lid flange 20a is formed on the rim of the first lid 20 and a second lid flange 25a is formed on the rim of the second lid 25. [ The first body flange 10a and the first cover flange 20a and the second body flange 10b are fixed to each other when the first lid 20 and the second lid 25 cover both open ends of the body 10. [ A plurality of bolts 40 are inserted through the first cover flange 25a and the second cover flange 25a and the bolts 40 are fixed by the nuts 42 so that the cover 20 and the main body 10 are bolted to each other .

However, when a plurality of filter housings are provided, when the operator opens or closes the main body 10 for replacing the filter 30, disinfecting, cleaning, or the like, the operator may dismantle a plurality of bolts 40 or nuts 42 Not only does it take a very long time, but it can be a very cumbersome task.
