Abstract

The utility model relates to a rotary exhaust smoke cover device for a mill, which is mainly composed of an outlet cover (6), a middle cover (7), an inlet cover (8), a rotary hood driven hydraulic cylinder (9), and a hood-locked hydraulic cylinder (10), wherein, the outlet and the inlet cover are connected with the mill body by an articulated shaft (5) for the rotary hood; the middle cover is fixedly arranged on the mill body; an outlet cover flue (1), a middle cover flue (3), and an inlet cover flue (4) are separately positioned on the outlet cover, the middle cover, and the inlet cover; the outlet and the inlet cover flues are compressed and sealed with the middle cover flue through an elastic gasket (2); the rotary hood driven hydraulic cylinder and the hood-locked hydraulic cylinder are arranged on the outlet and the inlet covers, and fixedly positioned on the mill body. The utility model can solve the problem of the difficult equipments maintenance before or after the equipments applications.

Description

A kind of milling train is with rotatable enclosure device

Technical field:

The utility model relates to aluminium plate band rolling mill fume extractor technical field, and particularly a kind of milling train is with rotatable enclosure device.

Background technology:

At present, the enclosure on traditional aluminium plate band rolling mill is a stationary structure, plant maintenance difficulty under the enclosure before the machine, behind the machine, make machine before, behind the machine in the maintenance of equipment overhead traveling crane can't descend hook.

Summary of the invention:

For overcoming the problem that above-mentioned conventional apparatus exists, the utility model provides a kind of milling train with rotatable enclosure device, it is by going into mouth mask, go out mouth mask and disposed hollow rotation jointed shaft separately device, make into mouth mask, go out mouth mask and can turn 90 degrees to the unit operation sidespin separately, can the solution machine before, plant maintenance difficult problem behind the machine.

For achieving the above object, the utility model adopts following technical scheme:

Described a kind of milling train is with rotatable enclosure device, it is mainly by going out mouth mask, intermediate cap, go into mouth mask, the petticoat pipe rotation drives hydraulic cylinder and petticoat pipe locking hydraulic cylinder constitutes, go out mouth mask and go into mouth mask and be connected on the milling train body by petticoat pipe rotation jointed shaft, intermediate cap is fixedly mounted on the milling train body, go out mouth mask, intermediate cap and go into to be respectively arranged with out the mouth mask flue on the mouth mask, intermediate cap flue and go into the mouth mask flue, go out the mouth mask flue and go into the mouth mask flue by elastic sealing gasket and intermediate cap flue pressing sealing, go out mouth mask and go into mouth mask to be provided with petticoat pipe rotation driving hydraulic cylinder and petticoat pipe locking hydraulic cylinder, the petticoat pipe rotation drives hydraulic cylinder and petticoat pipe locking hydraulic cylinder is fixedly mounted on the milling train body.

Owing to adopt aforesaid technical scheme, the utlity model has following superiority:

Described a kind of milling train is with rotatable enclosure device, plant maintenance difficult problem before can the solution machine, behind the machine, hollow jointed shaft and CO2 swivel joint are used and can solve CO2 tracheae dismounting problem, simultaneously because hydraulic cylinder, flue cushion that this enclosure has also disposed hydraulic cylinder that the petticoat pipe rotation drives, the locking of petticoat pipe working position, make enclosure motion action full automation from movable sealing etc.And operation is simple for it, and on-the-spot result of use is good.

Description of drawings:

Fig. 1 is a kind of milling train with rotatable enclosure device master TV structure schematic diagram;

Fig. 2 is a kind of milling train with rotatable enclosure device plan structure schematic diagram;

Fig. 3 be a kind of milling train with A in the rotatable enclosure device plan structure schematic diagram to view;

Number in the figure: 1-goes out the mouth mask flue; The 2-elastic sealing gasket; 3-intermediate cap flue; 4-goes into the mouth mask flue; 5-petticoat pipe rotation jointed shaft; 6-goes out mouth mask; The 7-intermediate cap; 8-goes into mouth mask; The rotation of 9-petticoat pipe drives hydraulic cylinder; 10-petticoat pipe locking hydraulic cylinder.

The specific embodiment:

As Fig. 1, shown in 2: this milling train is with rotatable enclosure device, it is mainly by going out mouth mask (6), intermediate cap (7), go into mouth mask (8), the petticoat pipe rotation drives hydraulic cylinder (9) and petticoat pipe locking hydraulic cylinder (10) constitutes, go out mouth mask (6) and go into mouth mask (8) and be connected on the milling train body by petticoat pipe rotation jointed shaft (5), intermediate cap (7) is fixedly mounted on the milling train body, go out mouth mask (6), intermediate cap (7) and go into to be respectively arranged with out mouth mask flue (1) on the mouth mask (8), intermediate cap flue (3) and go into mouth mask flue (4), go out mouth mask flue (1) and go into mouth mask flue (4) by elastic sealing gasket (2) and intermediate cap flue (3) pressing sealing, go out mouth mask (6) and go into mouth mask (8) to be provided with petticoat pipe rotation driving hydraulic cylinder (9) and petticoat pipe locking hydraulic cylinder (10), the petticoat pipe rotation drives hydraulic cylinder (9) and petticoat pipe locking hydraulic cylinder (10) is fixedly mounted on the milling train body.

Wherein, the operating position that goes out mouth mask (6) and go into mouth mask (8) can be locked hydraulic cylinder (10) by petticoat pipe and be tightened, go out mouth mask (6) and go into mouth mask (8) and can rotate around jointed shaft separately, intermediate cap (7) and go out mouth mask (6), go into flue between the mouth mask (8) and connect and to be sealed into the cushion sealing can be opened and seal automatically.
