Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

Referring to fig. 1-3, an embodiment of the invention discloses a rolling mill workshop exhaust system, which comprises a workshop body 1, wherein a rolling mill is arranged in the workshop body 1, an exhaust fan 2 is arranged on the outer side of the wall of the workshop body 1, the exhaust fan 2 is installed on the wall of the workshop body 1 through an installation frame 3, the air inlet side of the exhaust fan 2 faces the interior of the workshop body 1, a through hole 11 is formed in the wall of the workshop body 1 facing the air inlet side of the exhaust fan 2, the through hole 11 communicates the interior of the workshop body 1 with the air inlet side of the exhaust fan 2, and a filter cloth 4 is arranged on the inner side of the installation frame 3 facing the air outlet side of the exhaust fan 2.

Store up cloth room 5 is located to the upside of installation frame 3, store up cloth room 5 downside and be equipped with out cloth mouth 51, be equipped with pivot 8 in the cloth room 5 of storing up, the 8 convolutes of pivot are provided with filter cloth 4, just filter cloth 4 passes out cloth mouth 51 and hangs down into in the installation frame 3.

The cloth collecting groove 6 is arranged on the lower side of the mounting frame 3, a cloth inlet 61 is formed in the upper side of the cloth collecting groove 6, and the filter cloth 4 penetrates through the cloth inlet 61 and falls into the cloth collecting groove 6.

The cloth taking door 62 is arranged on the outer side of the cloth collecting groove 6, and the filter cloth 4 in the cloth collecting groove 6 can be taken away by opening the cloth taking door 62.

An oil collecting tank 7 is arranged at the bottom of the cloth collecting tank 6, and a filter screen structure 67 is arranged between the oil collecting tank 7 and the cloth collecting tank 6 for separation.

Store up the cloth room 5 both sides and be equipped with axle sleeve hole 52, 8 both ends of pivot are located respectively in the axle sleeve hole 52, the upside of axle sleeve hole 52 is equipped with arch 53, the downside of axle sleeve hole 52 is equipped with kicking block 9, the lower extreme of kicking block 9 is equipped with supporting spring 10, pivot 8 set up in on the kicking block 9, the upside of pivot 8 corresponds protruding 53 department is equipped with recess 81, protruding 53 embedding in the recess 81. Preferably, the upper end surface of the top block 9 is an arc-shaped concave surface adapted to the circumferential wall of the rotating shaft 8.

The working principle is as follows: the exhaust fan 2 is used for exhausting air into the workshop body 1, exhausting air with cooling oil in the workshop and purifying the air in the workshop; the cooling oil in the extracted air is absorbed by the filter cloth 4, so that the cooling oil is prevented from being discharged into the atmosphere, and the atmosphere is prevented from being polluted.
