Compared with the prior art, the utility model has the following advantages:
this application extrudes the feeding through the squeeze roll, avoids the sand stone caking, then carries the sand stone through spiral auger, and the less sand stone of in-process particle diameter of carrying can drop through first sieve to carry the second screening mechanism again through the effect of stock guide completely, can promote screening quality, and reduce the impact of sand stone to second screening mechanism.
Drawings
Fig. 1 is a schematic structural view of the present utility model.
The marks in the drawings are: the device comprises a 1-box body, a 2-first screening cylinder, a 3-first spiral auger, a 4-first screen plate, a 5-material guide plate, a 6-feed hopper, a 7-second screening cylinder, an 8-second spiral auger, a 9-material collecting plate, a 10-material guide section, a 11-baffle plate, a 12-screen plate, a 13-material collecting box, a 14-material stirring shaft, a 15-blanking port, a 16-second screen plate, a 17-blanking hole, a 18-charging hopper, a 19-extrusion roller, a 20-vibrator and a 21-material sweeping blade.
Detailed Description
Examples. The utility model provides a construction sand stone classifying screening installation, constitutes as shown in figure 1, including box 1, box 1 top-down be equipped with one-level screening mechanism, second grade screening mechanism and tertiary screening mechanism in proper order, one-level screening mechanism include first screening cylinder 2, first screening cylinder 2 one side upper end is equipped with charging hopper 18, is equipped with relative motion's squeeze roll 19 in the charging hopper 18, is equipped with first spiral auger 3 in the first screening cylinder 2, first screening cylinder 2 bottom is equipped with first sieve 4, first sieve 4 downside is equipped with stock guide 5, the end of stock guide 5 is connected with the feeder hopper 6 of second screening mechanism.
The second-stage screening mechanism comprises a second screening cylinder 7, a second spiral auger 8 is arranged in the second screening cylinder 7, a feed hopper 6 connected with the material guide plate 5 is arranged at one end of the second screening cylinder 7, a second screen plate 16 is arranged at the bottom of the second screening cylinder 7, and a material collecting plate 9 is arranged at the lower side of the second screen plate 16.
