Description

Anti-blocking screen mesh of circular swing screen

Technical Field

The utility model relates to a rocking sieve technical field specifically is a circular rocking sieve prevent stifled screen cloth.

Background

The design of the swing screen is a high-efficiency screening machine specially designed for meeting the requirements of screening with large yield and high precision. The in-process of screening the material is being carried out to current circular rocking sieve, and the material is drawn close to the screen cloth center, and screen cloth area itself is big, and the material that gathers together is difficult to removing all around under the influence of gravity, leads to material screening efficiency not good, and the material has the condition of caking in addition, appears raw materials jam and the problem that bonds on the screen cloth easily in the screening process. The prior circular swing sieve usually uses the clean tennis ball as a device for cleaning materials on the screen and preventing the screen from being blocked, but the use of the clean tennis ball also causes a plurality of corresponding problems. Firstly, a tennis cleaning plate capable of limiting the tennis cleaning movement space is matched when the tennis cleaning plate is used, but a channel for materials to pass through on the tennis cleaning plate is generally provided with a plurality of circular material leaking holes, the holes enable the materials to be more easily gathered and bonded on the tennis cleaning plate, and frequent jumping of the tennis cleaning plate easily causes the central part of a screen to be loosened, so that the screening efficiency is influenced; meanwhile, the random jumping of the net cleaning balls between the screen and the ball supporting plate easily causes a plurality of net cleaning balls to be clamped at one position, and the net cleaning effect is influenced; in addition, the added ball supporting plate and the net cleaning ball lead to more complex structure of the screen and more complicated maintenance and replacement process of the screen.

SUMMERY OF THE UTILITY MODEL

In view of the problem that exists among the prior art, the utility model provides a circular sieve that sways prevents stifled screen cloth, the technical scheme of adoption is, including the carriage, clear tennis, stratum reticulare and hoop, the bottom of carriage is the circular shape holds in the palm the ball board, hold in the palm the ball board and adopt the grid plate structure, the hourglass material hole that has the bar, the width in hourglass material hole is less than the diameter of clear tennis, the length in hourglass material hole is greater than the diameter of clear tennis, the center that holds in the palm the ball board is equipped with the support column, the top of support column is the sphere, be used for upwards supporting the stratum reticulare, it still is fixed with upwards bellied inner convex ring and evagination ring on the ball board to hold in the palm, inner convex ring and evagination ring set up with one heart, the lateral wall of carriage has the evagination edge.

As an optimized technical scheme of the utility model, the height ratio evagination ring of interior bulge loop is high, and the distance between interior bulge loop and the screen cloth and the distance between evagination ring and the screen cloth all are less than the diameter of clear tennis.

As an optimized technical proposal of the utility model, the number of the clean tennis balls in unit area in the inner convex ring is larger than the number of the clean tennis balls in unit area at the inner side of the outer convex ring.

As a preferred technical scheme of the utility model, the section of turning up along is "Z" font.

The utility model has the advantages that: the utility model adopts the strip-shaped material leaking holes, the length of which is larger than that of the cleaning net ball, and compared with the conventional round material leaking holes, the material leaking area is greatly increased, the material leaking holes are prevented from being blocked by the materials, and the material leaking efficiency is improved; the spherical surface of the central support column upwards supports the net layer, and the net layer is fixed on the support frame by the net hoop, so that the net layer can be tightened, the net layer is prevented from loosening and falling after long-time use, and the influence on the screening effect and the discharging efficiency due to the accumulation of materials in the center is prevented; the inner convex ring and the outer convex ring can gather the function of cleaning tennis balls, increase the bounce height of the cleaning tennis balls and improve the net cleaning effect; in addition, the everting edge of the supporting frame can be used as a handle for disassembling and assembling the ball supporting plate and the net layer, and the operation is convenient.
