Control the device that the pump orifice of two-maing ladle opens and closes
Technical field
The present invention relates in a kind of two-man ladle pump orifice opening and closing device, the especially alumina producer go out magnesium or the vacuum ladle of slagging tap on control two-man ladle in the pump orifice opening and closing device of high temperature magnesium melt or electrolytic slag mixture.
Background technology
In aluminum oxide production process, go out magnesium or the vacuum ladle of slagging tap is the equipment that is specifically designed in electrolytic cell suction high temperature magnesium melt or electrolytic slag mixture.Because the processing temperature of melt or electrolytic slag mixture is up to more than 800 ℃, need to realize more than 800 ℃ the open and close controlling of pump orifice under the hot environment, original switching mechanism normally adopts the structure of valve version, such structure needs many seals, and be easy to generate obstruction, workman's operating difficulties under the environment of hot operation simultaneously also will the necessary safety that guarantees the staff.Lack a kind of safe and effective pump orifice method for opening and closing and corresponding device thereof of two-maing ladle at present.
Summary of the invention:
The objective of the invention is: the device that provides a kind of control to two-man ladle the pump orifice switching, its processing ease, simple in structure, the pump orifice open and close controlling of can two-maing ladle safely and effectively is to overcome the deficiencies in the prior art.
The present invention is achieved in that and controls the pump orifice method for opening and closing of two-maing ladle, be provided with in pump orifice (8) upper end of two-maing ladle inner one can lifting bott stick (7), lifting by bott stick (7) realizes the unlatching of pump orifice (8) or closes, bott stick (7) is realized its lifting by being connected with the control device of outside.
The pump orifice of two-maing ladle opens and closes whirligig, it comprises wheel shank (11), wheel shank (11) is connected with reduction box (1), reduction box (1) top is connected with a screw rod (12), screw rod (12) upper end is connected with a connecting rod (2), and the upper end of connecting rod (2) is connected with the right-hand member of crossbeam (4), and crossbeam (4) below is connected with a fixing support (5), crossbeam (4) left end is connected with bott stick (7) upper end, and bott stick (7) lower end connects pump orifice (8).
Can also be connected with a handle (10) in bott stick (7) upper end, handle (10) right-hand member is connected with rocking bar (9) upper end, and rocking bar (9) is provided with a runing rest (3).
Described handle (10) right-hand member is provided with a frame (14), and rocking bar (9) passes frame (14) and is connected with handle (10).
Be more preferably in rocking bar (9) lower end and be surrounded by heat insulation layer.
Described connecting rod (2) lower end is provided with a tapped tube (13) that revolves, and revolves tube (13) and is threaded with screw rod (12) upper end.
Wherein, on crossbeam (4) and position that bott stick (7) is connected, also be provided with seal receptacle (6).
Owing to adopted technique scheme, compared with prior art, the present invention can be in the processing temperature of melt or electrolytic slag mixture up to more than 800 ℃ the time, the switching of pump orifice under the realization hot environment of safety, switching mechanism is not easy to stop up, and can effectively strict sealing when pump orifice is closed, and prevents that melt from spilling, and can not scald operating worker, security is good.Advantages such as the present invention also has simple in structure, and is easy to operate.
Description of drawings
Accompanying drawing 1 is a structural representation of the present invention.
The specific embodiment
Embodiments of the invention 1: control the pump orifice method for opening and closing of two-maing ladle, be provided with in inner pump orifice 8 upper ends of two-maing ladle one can lifting bott stick 7, lifting by bott stick 7 realizes the unlatching of pump orifice 8 or closes, bott stick 7 is realized its lifting by being connected with the control device of outside.
The structure of the pump orifice of two-maing ladle switching whirligig as shown in Figure 1, wheel shank 11 is connected with reduction box 1, reduction box 1 top is connected with a screw rod 12, screw rod 12 is provided with a tapped tube 13 that revolves with connecting rod 2 lower ends and is connected, the upper end of connecting rod 2 is connected with the right-hand member of crossbeam 4, and crossbeam 4 belows are connected with a fixing support 5, and crossbeam 4 left ends are connected with bott stick 7 upper ends, on crossbeam 4 and position that bott stick 7 is connected, also be provided with seal receptacle 6, can improve whole security; Bott stick 7 lower ends connect pump orifice 8; Be connected with a handle 10 in bott stick 7 upper ends, described handle 10 right-hand members are provided with a frame 14, and rocking bar 9 passes frame 14 and is connected with handle 10; Rocking bar 9 is provided with a runing rest 3, and rocking bar 9 can rotate in horizontal plane around runing rest 3, and rocking bar 9 lower ends are surrounded by heat insulation layer.
When mechanism works, because dress angular wheel in the reduction box 1 is used for the rotation of wheel shank 11 is converted into horizontally rotating of screw rod 12; And screw rod 12 is sleeved on connecting rod 2 lower ends and revolves on tube 13 the internal thread that (this connected mode is simple, and dismounting easily), so screw rod 12 hauls connecting rod 2 and moves both vertically, when turning to not simultaneously of wheel shank 11, connecting rod 2 will be in vertical reciprocating motion, thereby by the leverage of crossbeam 4, bott stick 7 is just made on-off action on pump orifice 8, and the workman only needs simple rotation wheel shank 11 just can.Owing to can also wrap heat insulation layer outside the wheel shank 11 on the reduction box 1, to prevent that the workman from being scalded.Realize the strictness sealing when pump orifice is closed under the hot environment, prevent that melt from spilling, then the oscillation in the pitch mode rocking bar 9, the rotating shaft of rocking bar 9 on support 3 rotated in fore-and-aft plane, because the right-hand member that frame (14) rides over handle 10 is passed in the upper end of rocking bar 9, rotate in horizontal plane so handle 9 drives bott stick 7, thereby allow pump orifice 8 and bott stick 7 fit closely; Dielectric layers is also being wrapped in rocking bar 9 lower ends, so the workman can not scalded.
