Yet, present electric flashboard door is not easily opened because of corrosion, stuck, broken teeth etc., and there is the blow-by of lock gate hatch excesssive gap, the shortcoming of not closing, lock gate hatch is poorly sealed, cause hot blast to return into coal-feeding conveyer, the phenomenon that causes like this coal-feeding conveyer belt to burn generally occurs, and has therefore seriously hindered the normal production of power plant.There are the shortcomings such as inefficiency in existing manual inserting plate door, slotting rod lock gate hatch.
The model utility content
In order to overcome the shortcoming of above-mentioned traditional lock gate hatch, the utility model provides a kind of can realize the effective hydraulic seal lock gate hatch of lower seal in off position.
A kind of hydraulic seal lock gate hatch is provided, comprise: hydraulic jack, oil cylinder pull bar, movable sealing flashboard, seal ring, upper main cylinder, lower main cylinder, steel disc elastic sealer, lock gate hatch main body, cylinder base flange, it is characterized in that, in the both sides of lock gate hatch main body, the flashboard flexible supporting frames is installed, hydraulic jack drives the to-and-fro motion of movable sealing flashboard by the oil cylinder pull bar, the air-tight movable flashboard produces gapless with seal ring and contacts, air-tight movable flashboard and the sliding contact of flashboard flexible supporting frames simultaneously is so that the hydraulic seal lock gate hatch opens and closes.
Plane machining at the seal ring that contacts with the lock gate hatch main body has the choke groove, and the choke groove is the triangle groove, thoroughly block hot blast by the choke groove every the wind decompression when the hydraulic seal lock gate hatch is closed, thereby the Push And Release of realizing the hydraulic seal lock gate hatch closes.
The hydraulic seal lock gate hatch also comprises automatically controlled part and hydraulic power unit, and wherein, automatically controlled part is controlled hydraulic power unit work, and hydraulic power unit is connected with hydraulic jack.
Hydraulic pressure gate door of the present utility model can solve inner product coal problem, lock gate hatch main body and seal ring slide by flexible supporting frames and play the flashboard open and close, seal ring and the plane process fine finishing of lock gate hatch main body, seal ring and lock gate hatch main body have been accomplished gap-free sealed, and the seal ring plane machining has the choke groove thoroughly to block hot blast.
The beneficial effect of hydraulic seal lock gate hatch provided by the utility model is:
1, sealing structure is smooth, and the hydraulic pressure output power is large, stable action.
2, the hydraulic seal lock gate hatch structurally adopts through cylindrical structure, and straight tube does not communicate with hydraulic seal lock gate hatch two avris chambeies, and eliminate hydraulic seal lock gate hatch inside and deposited the coal point, and inner without the dead angle structure, avoided the chute blockage problem.
3, unique flashboard elastic packing supporting frame contacts with the sliding contact of movable sealing flashboard and with the seal ring gapless, and seal ring and hydraulic seal lock gate hatch surface of contact are provided with the choke groove, and lower seal is effective in off position for the hydraulic seal lock gate hatch like this.
4, the automatically controlled part of hydraulic seal lock gate hatch of the present utility model adopts and sets " time " Control, guarantees that hydraulic seal lock gate hatch switch is accurate.Electric control part is arranged with " unlatching ", " closing " cue mark, and the lock gate hatch body is provided with and closes the unlatching indicator simultaneously, but the opened and closed positions of site operation personnel's intuitive judgment hydraulic seal lock gate hatch, on-the-spot as seen visual and clear, eliminated the phenomenons such as erroneous judgement, easy operating.
5, hydraulic seal lock gate hatch mode of operation both can realize controlling on the spot by push-button switch on the spot, can realize that again central station of floating dock can realize that by the DCS interface distant place controls.

Embodiment
Now, describe embodiment of the present utility model in detail, its example represents in the accompanying drawings, and wherein, identical label represents identical parts all the time.Below by embodiment being described with reference to the drawings to explain the utility model.
As shown in Figure 1, 2, hydraulic seal lock gate hatch of the present utility model comprises hydraulic jack 1, oil cylinder pull bar 2, movable sealing flashboard 3, seal ring 4, upper main cylinder 6, lower main cylinder 7, steel disc elastic sealer 8, lock gate hatch main body 9, cylinder base flange 10.
In the both sides of lock gate hatch main body 9, flashboard flexible supporting frames 5 is installed.Hydraulic jack 1 adopts four high-strength bolts to be connected with lock gate hatch body 9.Upper main 6 and lower main 7 is adopted stainless steels to make, and is that old name for the Arabian countries in the Middle East ground is round without the dead angle structure, can accomplish that the coal smoothness is logical.
Seal ring 4 and the 9 planes process fine finishing of lock gate hatch main body make seal ring 4 and lock gate hatch main body 9 accomplish gap-free sealed.
In addition, be processed with the triangle groove on the plane of the seal ring 4 that contacts with lock gate hatch main body 9 and be called choke groove (not shown in FIG.).Thoroughly block hot blast by the choke groove every the wind decompression when the hydraulic seal lock gate hatch is closed, thereby realize the Push And Release of hydraulic seal lock gate hatch.Make like this granular material enter from the suitable for reading of lock gate hatch, end opening flows out.
