Detailed Description

The technical solution of the present invention is described in further detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the following.

As shown in fig. 1-3, the utility model provides a sealed dust arrester installation of cement bistrique, include respectively can dismantle with 4 lateral walls of ball mill inlet pipe and 5 shells of bistrique and be connected the sealed cowling 1 that is used for wrapping the dust that bistrique 5 will overflow and carries out the collection, a plurality of roots can dismantle with 1 lateral wall of sealed cowling and be connected the tuber pipe 3 that gathers dust that is used for dust suction in the sealed cowling 1 and can dismantle with the tuber pipe 3 that gathers dust and be connected the dust extraction 2 that is used for forming the negative pressure in the sealed cowling 1, dust extraction 2's air-supply line 23 with respectively gather dust tuber pipe 3 and be connected and form the absorption recovery structure with ball mill inlet pipe 4 or ball mill discharging pipe. The sealing cover 1 is respectively detachably connected with the side wall of the ball mill feeding pipe 4 and the shell of the grinding head 5 through labyrinth seals.

In this embodiment, the sealing cover 1 is detachably mounted and connected, so that subsequent maintenance is convenient. The sealing cover 1 is detachably connected with the side wall of the ball mill feeding pipe 4 and the shell of the grinding head 5 through labyrinth seals, so that the sealing effect of the joint can be effectively improved.

The dust collector 2 further comprises a centrifugal fan 21 detachably connected with the air inlet pipe 23 and the air outlet pipe 22 respectively, and a driving motor 24 connected with the centrifugal fan 21 and used for driving the centrifugal fan 21 to rotate, wherein the driving motor 24 is in signal connection with a controller.
