A kind of siphon ejector
Technical field
The present invention is that a kind of potroom that is used for goes out the required supplementary equipment of aluminium, particularly relates to a kind of siphon ejector.
Background technique:
When potroom need go out aluminium, need in container is two-mand ladle, to introduce high temperature aluminum water the holding furnace with siphon device, existing siphon device is the conveyance conduit of both ends open, and between inlet opening and delivery outlet, be provided with a vacuum pumping device, during the container that earlier the syphon tube two ends is inserted holding furnace and splendid attire high temperature aluminum water is in use respectively two-mand ladle, then utilize vacuum pumping device that syphon tube is evacuated, the aluminium water under the effect of negative pressure the container of splendid attire high temperature aluminum water being two-mand ladle is drawn onto holding furnace.Because of what extract is high temperature aluminum water, and ambient air temperature arrives about 950 ℃, and common vaccum-pumping equipment can't be competent at, and the ability high-temperature service is expensive again.
Summary of the invention:
The objective of the invention is to: a kind of siphon ejector is provided, produces the needed power of siphon indirectly, thereby finish the aluminium that of potroom by the present invention.
Technological scheme of the present invention, comprise T type three-way pipe, also comprise nozzle (4), nozzle (4) is connected with the lower nozzle (1) of T type three-way pipe, nozzle (4) is loaded in the T type three-way pipe, and the air outlet of nozzle (4) is arranged between the lower nozzle (1) and the mouth of pipe (2) of T type three-way pipe.
Nozzle (4) is threaded with being connected to of lower nozzle (1) of T type three-way pipe.
The middle mouth of pipe (2) of T type three-way pipe connects a sealing hole capital after selling all securities (6).
Sealing hole capital after selling all securities (6) is a hollow cylinder.
Sealing hole capital after selling all securities (6) upper end is provided with suction port (9), and there is draining drain plug (7) sealing hole capital after selling all securities (6) lower end, and sidewall has one and connecting port (13).
Compared with the prior art, the present invention is made of simple nozzle and T type three-way pipe, have under the compressed-air actuated situation at aluminium discharging plant, utilize the present invention and pressurized air to reach the required vacuum state that reaches of siphonage takes place in the syphon tube, aluminium water during syphon tube is two-mand ladle the container of splendid attire high temperature aluminum water under the effect of negative pressure is drawn onto in the holding furnace, finish siphonic process by simple equipment, reduce expenses, and the present invention is simple in structure, easy to use, practical.

Embodiment
Embodiment: as shown in Figure 1, the present invention mainly is made of T type three-way pipe and nozzle 4, nozzle 4 is installed in the T type three-way pipe, be connected by the screw-internal thread fit of the outside thread on the nozzle 4 with the lower nozzle 1 of T type three-way pipe, the air outlet of nozzle 4 is between the lower nozzle 1 and the middle mouth of pipe 2 of T type three-way pipe, the middle mouth of pipe 2 of T type three-way pipe connects a sealing hole capital after selling all securities 6, sealing hole capital after selling all securities 6 is by steel pipe 12, cover plate 10, cover plate 11, seal washer 8, plug screw 7, joint 9 and joint 13 combine, the sealing hole capital after selling all securities that is combined into has joint 9,13 two connection mouths that can be connected with miscellaneous equipment of joint and one are by seal washer 8, draining and sewage draining exit that plug screw 7 constitutes, the sidewall joint 13 of the middle mouth of pipe 2 of T type three-way pipe and sealing hole capital after selling all securities 6 is coupled together, formed the equipment that three external-connected ports are arranged, these three ports are respectively joints 9, the upper orifice 3 of T type three-way pipe and the suction port of nozzle 4, joint 9 is processed into trapezoidal flexuose and is convenient to connect syphon tube; The suction port of nozzle 4 connects pressurized air by sebific duct, and for the ease of connecting sebific duct, the suction port of nozzle 4 also is processed into trapezoidal flexuose; Among the figure, steel plate 14, steel plate 15 are welded on the sealing hole capital after selling all securities, are convenient to fixedly the present invention.When syphon tube needs work, comperssed air starting work by the present invention and aluminium discharging plant, when pressurized air from the suction port of nozzle 4 inject fast, when the upper orifice 3 of T type three-way pipe flows out fast, then produce a kind of suction and will seal air sucking-off in the hole capital after selling all securities 6, so just be sucked out with the air in the syphon tube that joint 9 is connected, form required vacuum state, produced negative pressure, started whole siphonic process.On the sealing hole capital after selling all securities 6 pressure gauge 9 is installed, can observe the pressure size in the sealing hole capital after selling all securities at any time, so that by regulating the compressed-air actuated pressure size by the suction port injection of nozzle 4, plug screw 7 is to be used for discharging in the sealing hole capital after selling all securities because water that variation in pressure produced and the slag from two-maing ladle and sucking.
