Background technology:
At present, be subjected to liquid bath etc. to go out all to have designed the hopper parts on the aluminium equipment in vapour liquid separator, vacuum, these hopper parts often need overhaul.The structure of existing hopper access hole is directly will be welded on the bucket wall place of access opening with the round steel pipe of pipe flange, and the access door of the pipe flange lid being made with bolt, nut is fixed on the flange, and the centre is separated with a seal with elastometic washer.Because the needs of practical structures, circular access hole sealing cover commonly used is not suitable for some hopper, therefore, and necessary adapted rectangle access hole on some hopper, and its seal request strictness.
Summary of the invention:
The purpose of this utility model is: provide the hopper rectangle access hole sealing cover of a kind of novel structure, good sealing effect, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: it comprises hopper (1), and rectangle access hole (9) is arranged on hopper (1), and hopper (1) is connected with bloom (2); Access door (8) is connected with channel-section steel (6), and rubber pad (7) is arranged in channel-section steel (6); Hopper (1) is connected with access door (8), and bloom (2) is close to rubber pad (7).
Channel-section steel (6) is a rectangular loop, is welded on the access door (8), and bloom (2) is a rectangular loop, is welded on rectangle access hole (9) hopper (1) on every side, and the rectangular loop of channel-section steel (6) is concentric with the rectangular loop of bloom (2).
In the middle of the rectangular loop of channel-section steel (6), be welded with steel plate (3).
Hopper (1) is connected by bolt (4), nut (5) with access door (8); Bolt (4) is welded on the hopper (1), be distributed in bloom (2) around.
The cross-sectional width of bloom (2) is less than the cross-sectional width of rubber pad (7).
Bolt (4) uses plain bolt or opens bolt soon.
During work, cover access door (8), rubber pad (7) promptly is close on the bloom (2), with bolt (4), nut (5) access door (8) is fixed on the hopper (1), snap-in force makes rubber pad (7) being deformed into groove shape trim automatically with bloom (2) joint place, reaches effective sealing.
Compared with prior art, the utlity model has advantages such as novel structure, good sealing effect.
Embodiment:
Embodiment of the present utility model: at first, select for use general steel plate to make access door 8, select for use the regular troughs steel to make channel-section steel 6 and be welded on the access door 8 and surround rectangular loop, welding steel 3 in rectangular loop, stickup rubber pad 7 channel-section steel 6 in; Then, weld bloom 2 and surround rectangular loop on hopper 1, this rectangular loop is concentric with the rectangular loop of channel-section steel 6, and the cross-sectional width of bloom 2 is less than the cross-sectional width of rubber pad 7; Weld bolt 4 on the body of hopper 1, and bolt 4 is evenly distributed on around the rectangular loop of bloom 2, and bolt 4 uses plain bolt or opens bolt soon; During use, access door 8 is covered on the rectangle access hole 9 of hopper 1, on bolt 4, screw nut 5 and get final product.
