Description
Technical field
This utility model belongs to rotary seal structure technical field, seals in especially relating to screw ship unloader rotary column
Structure.
Background technology
Now screw ship unloader rotary column inner seal structure uses sealing gasket axial seal, sees Fig. 1, due to upper and lower fall
Between material pipe there is error relatively greatly in axiality, is easily caused seal failure, causes material from leakage, and one is to pollute environment, and two is wave
Take material, then be to easily cause equipment fault.
Summary of the invention
The purpose of this utility model is to improve the deficiency of prior art and provide a kind of simple in construction, axiality to allow by mistake
Difference is big, the screw ship unloader of end face seal rotary column inner seal structure.
The purpose of this utility model is achieved in that a kind of screw ship unloader rotary column inner seal structure, including rotation
The funnel of capstan head, upper material blanking tube, dropping material pipe and conveying equipment, be characterized in the material blanking tube funnel by flange with rotary column
Connecting and follow rotary column and move, the vertical edge of L-shaped sleeve seal cover for seat is fixed on outside dropping material pipe, L-shaped sleeve seal cover for seat
Horizontal edge is between top cover labyrinth and lower sealing cover, and the upper and lower lid that seals is by seam Flange joint, lower sealing cover and dropping material pipe
Fixing connection, dropping material pipe is connected with conveying equipment fixing below by flange.
In order to realize the purpose of this utility model further, it can be the upper and lower horizontal stroke sealing lid and L-shaped sleeve seal cover for seat
Sealing ring it is provided with between limit.
Compared with the prior art this utility model has following distinguishing feature and good effect: this utility model uses L-shaped
Sleeve seal cover for seat and upper-lower seal lid connect upper and lower material blanking tube, use end face seal, and such axiality allowable error is big, both full
Foot is tightly connected requirement, easy installation and removal again, simple in construction, good sealing effect；Upper and lower sealing is covered and L-shaped sleeve seal
It is provided with sealing ring between the horizontal edge of cover for seat, further ensures sealing effectiveness, it is to avoid the leakage of material.
Accompanying drawing explanation
With embodiment, this utility model is described in further details below in conjunction with the accompanying drawings.
Fig. 1 is existing rotary column sealed structural representation.
Fig. 2 is a kind of structural representation of the present utility model.
Fig. 3 is a kind of structural representation of upper and lower close capping region of the present utility model.
Detailed description of the invention
A kind of screw ship unloader rotary column inner seal structure, with reference to Fig. 2, is that upper material blanking tube 2 is by flange and rotary column
Funnel 1 connect and follow rotary column and move, the vertical edge suit of L-shaped sleeve seal seat 6 is fixed on outside material blanking tube 2, L-shaped sleeve
The horizontal edge of seal receptacle 6 is between top cover labyrinth 3 and lower sealing cover 4, and the upper and lower lid that seals is by seam Flange joint, lower seal
Lid 4 is fixing with dropping material pipe 5 to be connected, and dropping material pipe 5 is connected with conveying equipment 8 fixing below by flange.
In order to prevent material from leakage further, with reference to Fig. 3, at top cover labyrinth 3, lower sealing cover 4 and L-shaped sleeve seal seat 6
Horizontal edge between be provided with sealing ring 7.
