Detailed Description

The following description is only for the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention.

Example (b): as shown in fig. 1, 2, 3, 4 and 5, a screen structure for screening dry vibrating material comprises an annular screen frame 1, a screen support frame 2, and a screen body 3, and further comprises an upper open ring unit 4 disposed in the annular screen frame 1, a lower fixing ring unit 5 disposed in the annular screen frame 1 and used for pressing the annular edge of the screen body 3 on the upper open ring unit 4, a middle block unit 6 disposed on the screen support frame 2 and used for protecting the screen body 3 by blocking and decelerating the material to be filtered, and a limit plate unit 7 disposed on the screen support frame 2 and used for protecting the lower fixing ring unit 5.

In this embodiment, the upper split ring unit 4 is fitted with the lower fixing ring unit 5 for clamping the side of the screen main body 3, which has the advantage that the screen is less likely to fall off compared to the conventional manner in which the side of the screen is nailed to the frame, and the middle block unit 6 is used for a preferential buffering of a large amount of falling material, so that the screen main body 3 is relatively less likely to be broken.

And finally, the limiting plate unit 7 is used for preventing the connecting piece on the lower fixing ring unit 5 from falling into the raw material, and the screw or bolt on the upper opening ring unit 4 falls on the screen body 3 even if the screw or bolt falls off, so that the anti-falling operation is not needed, and the complexity of the screen structure can be further simplified.

The upper split ring unit 4 includes an upper ring 401 inserted into the annular screen frame 1 and located above the screen body 3, an upper elastic ring 402 disposed on an outer circumferential surface of the upper ring 401, an upper bolt 403 disposed on the upper ring 401 and used for connecting the annular screen frame 1, and an annular groove 404 disposed on an annular lower surface of the upper ring 401 and used for snap-fitting the screen body 3. The lower fixing ring unit 5 includes a lower ring 501 inserted into the annular screen frame 1 and located below the screen body 3, a lower elastic ring 502 provided on an outer circumferential surface of the lower ring 501, a lower bolt 503 provided on the lower ring 501 and used to connect the annular screen frame 1, and an annular protrusion 504 provided on an annular upper surface of the lower ring 501 and used to press the screen body 3 in the annular groove 404.

In this embodiment, the annular groove 404 is matched with the annular protrusion 504 to clamp the screen main body 3, and the clamping manner has the advantages of large clamping area and high clamping strength, so that the annular side edge of the screen main body 3 is less prone to falling off.

The middle block unit 6 comprises vertical plates 601 respectively arranged on the two screen support frames 2, transverse cylinders 602 arranged on the opposite inner side surfaces of the vertical plates 601, and conical blocks 603 arranged on the opposite end surfaces of the two transverse cylinders 602 and used for blocking and decelerating materials to be filtered.

In this embodiment, the vertical plate 601, the horizontal cylinder 602 and the conical block 603 are made of iron, so as to ensure a high impact resistance effect, and the conical block 603 blocks the falling dry vibration material, so that the material falls at a relatively slow speed, and the screen main body 3 is prevented from being worn and broken at an excessive speed.

The intermediate block unit 6 further includes a connection post portion 604 provided on a lower surface of the conical block 603 and adapted to fixedly hold a central region of the screen body 3. The connection column part 604 includes an internal thread groove 604a formed on the lower surface of the conical block 603, a connection stud 604b formed on the internal thread groove 604a and passing through the central hole 8 of the screen downward, and internal thread hole plates 604c formed on the connection stud 604b and located at the upper and lower sides of the screen body 3, respectively.

In this embodiment, the circle center area of the screen main body 3 is the position where the hole is most easily broken, the conical block 603 is firstly made to be worn away too fast by the way of buffering and decelerating, and the inner thread hole plate 604c clamps the circle center area of the screen main body 3 from top to bottom and then fixes the circle center area on the connecting stud 604b, so that the combined fixing way of "outer circle fixing and middle concentrated fixing" can be realized, and the screen main body 3 is further ensured not to be damaged too fast.

The limiting plate unit 7 comprises a downward extending plate 701 arranged on the screen support frame 2, a through hole 702 arranged on the downward extending plate 701, a transverse stud 703 arranged on the through hole 702, a limiting plate 704 arranged on the opposite end faces of the two transverse studs 703 and used for covering and protecting the lower bolt 503, and an adjusting nut 705 arranged on the transverse stud 703 and located on the opposite outer side of the downward extending plate 701 and used for driving the limiting plate 704 to clamp the lower ring 501. The limiting plate 704 is further provided with an elastic sheet 706 attached to the lower ring 501.

In this embodiment, if the lower bolt 503 falls, it may be dangerous to mix the lower bolt into the raw material, so that the lower bolt 503 is ensured not to fall from the bolt hole even if it is loosened by introducing the stopper plate 704.

The elastic piece 706 compresses the inner annular surface of the lower ring 501, so as to further reinforce the lower ring 501.

The mesh size of the screen main body 3 is 0.5-2.0 mm. The number of the screen mesh support frames 2 is two, and the two screen mesh support frames are arranged on the outer ring surface of the annular screen mesh frame 1 in a circle-center symmetrical relationship.

Finally, this embodiment is through the mode of the effective area that passes through of proper loss screen cloth for screen cloth main part 3 is difficult for dropping, is difficult for middle broken hole, finally guarantees the lasting validity of raw materials screening operation.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art. These are non-inventive modifications, which are intended to be protected by patent laws within the scope of the appended claims.
