In the figure: 1. a limiting bulge; 2. a top groove; 3. a filtration section; 4. a fan body; 5. a side groove; 6. a cover plate; 7. positioning the projection; 8. unwinding rollers; 9. a tension roller; 10. a wind-up roll; 11. an end plate; 12. a rectangular opening; 13. the motor is driven.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

As shown in the figure, the utility model discloses a fan body 4, the filter tube section 3 that is linked together with fan body 4 and locate the filter assembly in the filter tube section 3, open the 3 lateral walls of filter tube section has rectangle opening 12, and the 3 lateral walls of filter tube section are located rectangle opening 12 position and can dismantle and be connected with apron 6, and accessible fastening bolt installs apron 6 in the 3 outsides of filter tube section in this example. Filter component including crisscross rotation connect in proper order in filter tube section 3 unreel roller 8, tensioning roller 9 and wind-up roll 10, unreel roller 8, tensioning roller 9 and wind-up roll 10 perpendicular to apron 6 setting, it is connected with driving motor 13 to unreel roller 8 and wind-up roll 10. In the actual use process, the oil absorption paper is sleeved outside the unwinding roller 8, one end of the oil absorption paper is fixed outside a paper tube of the winding roller 10 through the tensioning rollers 9 which are arranged in a staggered mode, when oil smoke passes through the filtering pipe section 3, the oil smoke is fully contacted with the oil absorption paper, the oil smoke in the gas is filtered, after the oil smoke is used for a period of time, a worker manually starts the two driving motors 13 to drive the unwinding roller 8 and the winding roller 10 to rotate, the oil-stain-coated paper can be wound, and new oil absorption paper is pulled out.

According to the above embodiment, preferably, the tension roller 9 is provided with a plurality of tension rollers 9, in this example, the tension roller 9 is provided with 2 tension rollers, and this arrangement can effectively increase the contact area between the oil smoke and the oil absorption paper, and improve the filtering effect.
