And the quality of the follow-up concrete and the like in the using process can be seriously influenced without cleaning. In addition, the sand screening efficiency of the existing sand screening device is low, manual assistance is needed, and the construction progress is seriously influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the not enough and provide a building site is with screening sand impurity removal device for above-mentioned technique, it can sieve husky efficient and can classify the clearance with iron impurity.

In order to achieve the above object, the utility model relates to a sand screening and impurity removing device for building site, which comprises a horn-shaped filter sieve, wherein rotating rings are arranged at two ends of the horn-shaped filter sieve, the rotating rings are fixed on a frame, the rotating rings are rotatably connected with the filter sieve, a power mechanism is arranged on the frame, the power mechanism drives the filter sieve to rotate in the rotating rings, two ends of the filter sieve are both of open structures, the diameter of one end is smaller than that of the other end, one end of the filter sieve with small diameter is an input end, one end of the filter sieve with large diameter is an output end, the central axis of the filter sieve is horizontally arranged, a sand input pipe is arranged at the input end of the filter sieve, a first conveying belt is arranged under the filter sieve, the first conveying belt is used for outputting filtered sand, and a second conveying belt is arranged at the lower end of the output end of the filter sieve, no. two large granule outputs that the conveyer belt filtered out in with husky material, the interval is provided with a plurality of electro-magnets that set up along the axial on the inner wall of filter sieve, input department at the filter sieve is provided with the power, set up the controller on the power, the power passes through the controller and is connected with the electro-magnet, top inside the filter sieve is provided with the collecting vat, collecting vat slope downwardly extending extends to the filter sieve outside, below at the collecting vat lowest end is provided with No. three conveyer belts, No. three conveyer belts are exported the impurity that gets into the collecting vat, the filter sieve rotates the in-process, when the electro-magnet rotated to the highest position, the vertical downward projection of this electro-magnet is all located inside the collecting vat.

The collection groove and the horizontal plane form an included angle of 15-30 degrees.

Among the above-mentioned scheme, carry husky material to the filter sieve from husky material input tube, rotate the in-process at the filter sieve, husky material can pass the filter sieve under the effect of gravity and get into the output on the conveyer belt, and the impurity of large granule can follow the filter sieve and discharge from the output and get into the output on the conveyer belt No. two, in large granule impurity output process, large granule impurity can pass through the region at electro-magnet place, impurity at iron can be adsorbed on the electro-magnet, and rotate to highest position department along with the rotation of filter sieve, at this moment, the controller cuts off the current transport between the electro-magnet of power and highest position department, thereby make the suction on the electro-magnet disappear, the impurity of iron is dropped in the collecting vat and is slided to No. three conveyer belts and is exported. The separation among sand, large-particle impurities and iron impurities is realized, and the quality of the sand is ensured; and the separation efficiency is high, the automation is finished, and the labor input is reduced.

The utility model provides a sand screening impurity removal device for building site, it can separate the large granule impurity and the iron impurity in the husky material through reasonable structural design, and separates high-efficiently thoroughly, promotes husky material quality.
