Technical Field

[0001] The invention belongs to the technical field of powder collection, and in particular relates to an automatic alignment discharge valve. Background Art

[0002] In manufacturing and other enterprises, a large amount of powder will be generated during the processing. The powder will continue to diffuse into the space. When it reaches a certain concentration, it is easy to cause safety accidents, and the powder needs to be collected. In the prior art, a discharge valve is used to collect the powder. The discharge valve includes a valve body, an opening is opened on the valve body, and a lifting valve stem is connected to the valve body. A sealing plate is fixedly connected to the upper side of the valve stem. When no discharge is required, the valve stem drives the sealing plate to rise, and the sealing plate seals the opening. When the material is discharged, the valve stem descends and the sealing plate descends. In this design, after the sealing plate descends, when the material is discharged, dust and the like will accumulate on the sealing plate, which needs to be purged. Dust will be generated during the purging process, and the collection effect is not good. Summary of the invention

[0005] In the present invention, the valve body is connected to the reactor through the opening; when the valve body needs to be sealed, the valve stem rises, and when the sealing support plate contacts the valve body at the opening, the sealing support plate is automatically aligned under the action of the ball head, and the opening is sealed, and the sealing performance is good; the present invention has a simple structure, and when the valve stem descends to a certain position, the sealing gasket is blocked and stirred, and the valve stem continues to descend, and the sealing support plate rotates around the ball head and tilts, so that when the material falls from the upper end, the powder will automatically slide down on the inclined sealing plate, and there will not be a large amount of powder accumulation, and no dust will be raised during the purging; it can be applied to aggregate work.

[0006] In order to further improve the sealing performance, a sealing gasket is provided on the outer periphery of the sealing support plate. A connecting groove is opened on the upward side of the sealing gasket. A pressure plate is provided at the connecting groove. The sealing support plate is pressed against the downward side of the sealing gasket. The pressure plate is fixedly connected to the sealing support plate, and the sealing gasket can seal the opening.

[0007] In order to prevent the spherical ball from falling off the sealing support plate, a spherical ball pressing block is fixedly connected to the lower side of the sealing support plate to prevent the spherical ball from falling off upwards.

[0008] In order to further achieve the resetting of the sealing support plate, a mixing stop step is provided in the valve body just below the opening, and a spring is mounted on the connecting shaft, the upper end of the spring can abut against the upper side of the ball head pressure block, and the lower end of the spring can abut against the upper side of the mixing stop step; in this design, when the valve stem rises from the lowest position, the sealing support plate will automatically and gradually turn flat under the action of the lower end spring, so that when it reaches the uppermost end, the automatic alignment seal will not be affected by the excessive inclination angle.

DETAILED DESCRIPTION

[0017] like Figure 1 to Figure 4The automatic alignment feeder valve shown in the figure comprises a valve body 1 and a sealing support plate 11. An opening 3 is opened on the upper side of the valve body 1. A shell 2 is fixedly connected to the lower side of the valve body 1. A liftable valve stem 5 is connected to the shell 2. A roller 8 is rotatably connected to the shell 2. The valve stem 5 abuts against the outer periphery of the roller 8. The valve stem 5 is between the roller 8 and the driving gear 6. The structure for lifting the valve stem 5 is as follows: the driving gear 6 is rotatably connected to the shell 2, and the lower part of the valve stem 5 is fixedly connected to the lower part of the valve stem 5. There is a movable rack 7, which meshes with the driving gear 6; the lower part of the valve stem 5 is connected to the valve body 1 through a linear bearing 9, and the valve stem 5 extending upward into the valve body 1 is connected with a connecting shaft 4, and a global head 401 is provided on the upper side of the connecting shaft 4, and the global head 401 is connected to the sealing support plate 11, and the global head 401 can rotate freely in the sealing support plate 11, and a mixing step 15 is provided in the valve body 1. When the sealing gasket 12 drops to the position of the mixing step 15, the sealing gasket 12 tilts.

[0018] In order to further improve the sealing performance, a sealing gasket 12 is provided on the outer periphery of the sealing support plate 11, and a connecting groove is opened on the upward side of the sealing gasket 12. A pressure plate 10 is provided at the connecting groove. The sealing support plate 11 is pressed tightly on the downward side of the sealing gasket 12. The pressure plate 10 is fixedly connected to the sealing support plate 11. The sealing gasket 12 can seal the opening 3. The lower side of the sealing support plate 11 is fixedly connected to a ball head pressure block 14 for placing the global head 401 to fall off upward.

[0019] In order to further achieve the resetting of the sealing support plate 11, a mixing step 15 is provided in the valve body 1 directly below the opening 3, and a spring 13 is mounted on the connecting shaft 4. The lower end of the spring 13 can abut against the upper side of the mixing step 15, and the upper end of the spring 13 can abut against the upper side of the ball head pressure block 14.

[0020] In the present invention, the valve body 1 is connected to the reactor via the opening 3; when the valve body 1 needs to be sealed, the driving gear 6 is controlled to rotate, and the rotation of the driving gear 6 drives the movement of the transmission rack, and the rotation direction of the driving gear 6 is controlled to make the transmission rack move up, and the valve stem 5 rises. When the sealing support plate 11 contacts the valve body 1 at the opening 3, the sealing support plate 11 is automatically aligned under the action of the global head 401, and the opening 3 is sealed; when it is necessary to discharge materials, the valve body 1 is connected to the reactor, the driving gear 6 rotates in the opposite direction, the transmission rack moves down, and the valve stem 5 descends. When the valve stem 5 descends to the position of the mixing step 15, the sealing The sealing support plate 11 is tilted, and the dust falls downward from the opening 3. The present invention has a simple structure. When the valve stem 5 descends to a certain position, the sealing gasket 12 is blocked and stirred, and the valve stem 5 continues to descend, and the sealing support plate 11 rotates around the ball head and tilts, so that when the material falls from the upper end, the powder will automatically slide down on the inclined sealing plate, and there will not be a large amount of powder accumulation, and no dust will be raised during the purging. When the valve stem 5 rises from the lowest position, the sealing plate will automatically and gradually turn flat under the action of the lower end spring 13, so that when it reaches the uppermost end, the automatic alignment and sealing will not be affected by the excessive inclination angle. It can be applied to aggregate work.
