Description
Technical Field
The utility model relates to a screening equipment field especially relates to a prevent windrow screening plant.
Background
In the process of crushing, dissociating and sorting ores in a dressing plant, a sieve is often used for carrying out size fraction screening and sorting operation on crushed materials, and the conventional operation method is to directly feed the materials into the screening machine through a belt conveyor for size fraction screening and sorting operation. The direct screening machine that gives the material through band conveyer carries out size fraction screening separation operation, often can meet the material and get into the screening machine, because the material transport capacity is great leads to the local material of screening machine sifter to pile up thickly to reduce screening machine screening efficiency.
SUMMERY OF THE UTILITY MODEL
For overcoming the above-mentioned not enough that current screening plant exists, the utility model aims to solve the technical problem that: the screening device can prevent stacking and improve screening efficiency.
The utility model provides a technical scheme that its technical problem adopted is:
the piling-preventing screening device comprises a screen surface which is obliquely arranged, wherein an even material device is arranged at the middle-upper part of the screen surface, the even material device is of a comb-tooth-shaped structure, and the length direction of the even material device is vertical to the oblique direction of the screen surface.
Further, the material homogenizing device comprises a bottom plate and vertical plates, wherein the bottom plate is fixed on the screen surface, and the vertical plates are uniformly arranged on the bottom plate at intervals.
Further, the bottom plate is fixedly connected with the screen surface through bolts.
Further, the height of the vertical plate is 10-15 cm, and the height of the vertical plate is the same as the distance between two adjacent vertical plates.
The utility model has the advantages that: through set up the even material ware of comb-tooth form on the sifter of screening machine, the material becomes more dispersion behind even material ware, then reachs the sifter and carries out size fraction screening separation operation, can effectively overcome the screening machine material and pile up the problem of excessive thickness, improves screening machine screening efficiency, can let the material have a buffering after getting into the screening machine simultaneously, reduces the impact of material to the screening machine sifter, improves the life of screening machine sifter. The whole device is simple and easy to operate, improves the screening efficiency of the screening machine, can prolong the service life of the screening surface of the screening machine, reduces the labor cost, greatly reduces the production cost of enterprises, and creates economic benefits for the enterprises.

Marked in the figure as 1-screen surface, 2-uniform material device, 21-bottom plate, 22-vertical plate and 23-bolt.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in fig. 1 and 2, the utility model discloses a prevent windrow screening plant, including the sifter 1 that the slope was arranged the well middle and upper position of sifter 1 is equipped with even material ware 2, even material ware 2 is comb-tooth-shaped structure, and its length direction is perpendicular with sifter 1's incline direction. The upper middle part of the screen surface 1 refers to a relatively high part on the inclined surface of the screen surface 1 shown in fig. 1, and a blanking area is ensured to be positioned between the top of the screen surface 1 and the uniform material device 2. The comb-tooth-shaped structure is similar to a common comb shape, and the length direction of the comb-tooth-shaped structure is the arrangement extending direction of comb teeth.
The utility model discloses an increase an even material ware 2 on the sifter 1 of traditional screening machine, the material of carrying from the belt feeder falls on the sifter of the 2 upper reaches sides of even material ware earlier, then by homodisperse under the vibration of gravity and sifter behind even screening ware 2, the material of dispersion accomplishes the screening at the in-process of downstream. Because the dispersion effect of even material ware 2 has been passed through in advance for the material no longer piles up, thereby improves screening efficiency, and the material has a buffering after even material ware 2 simultaneously, and reducible material improves the life of screening machine sifter 1 to the impact of screening machine sifter 1.
Because even material ware 2 receives the material impact for a long time, consequently need possess sufficient structural strength, preferably adopt the higher steel plate structure of intensity, including bottom plate 21 and riser 22, bottom plate 21 is fixed on sifting surface 1, and riser 22 is even interval setting on bottom plate 21. For convenient maintenance and replacement, the bottom plate 21 can be fixedly connected with the screen surface 1 through bolts 23.
Considering the type of the screened materials, in order to ensure good flow capacity, the height of the vertical plate 22 is controlled to be 10-15 cm, and the height of the vertical plate 22 is the same as the distance between two adjacent vertical plates 22. In addition, a distance of about 20cm is preferably left between the two ends of the homogenizing material device 2 and the two side surfaces of the screen surface 1, if the homogenizing material device 2 is blocked, the homogenizing material device can pass through the space between the two sides, and when the situation occurs, the homogenizing material device 2 is cleaned.
The utility model discloses a set up a comb dentate even material ware 2 on the sifter 1 of screening machine, the material becomes more dispersed after even material ware 2, then reachs sifter 1 again and carries out the size grade screening and select separately the operation, can effectively overcome the screening machine material and pile up the problem of excessive thickness, improves screening machine screening efficiency, can let the material have a buffering after getting into the screening machine simultaneously, reduces the impact of material to the screening machine sifter, improves the life of screening machine sifter. The whole device is simple and easy to operate, improves the screening efficiency of the screening machine, can prolong the service life of the screening surface of the screening machine, reduces the labor cost, greatly reduces the production cost of enterprises, and creates economic benefits for the enterprises.
