The beneficial effects of the invention are as follows:
1. when sand is discharged from a traditional three-return dryer, the sand is positioned in a separation groove of an outer cylinder, and the sand rotates to reach about 45 degrees upwards along the horizontal direction of the dryer axis and begins to flow out the sand downwards and outwards along a discharge cone, and the sand flows out while rotating. Because the channel from which the sand flows out is also an air-out channel, the sand flows down from the upper portion of the tapered cylinder partition wall groove. And the sand outlet channel positioned below the conical cylinder baffle groove can not outlet sand and only outlet air. Then, the air flowing out of the sand outlet channel at the lower part blows the sand falling from the sand outlet channel at the upper part to form a waterfall in the air of the sand, and fine sand in the waterfall of the air sand is introduced into the dust remover by the induced draft fan in the sand outlet bin, so that the load of the dust remover is increased, and the circulation and dust removal of air are not facilitated.

2. The conventional sand dryer has a discharging bin, a heavy hammer air locking valve is adopted, and a heavy hammer air locking plate is generally horizontally arranged. And the sand of the sand outlet bin presses the heavy hammer air locking plate open to form a sand flowing port. At the sand flow port, the sand face angle of the sand flow is larger than the repose angle of the sand. Sand flows are generated around the entire periphery of the weight lock air plate. The opening of traditional weight lock aerofoil can not let the sand flow to maximum opening part preferentially, simultaneously, the quicksand can not form airtight sealed flow around the board, leads to the draught fan to inhale the outside wind in the play feed bin, has formed new dirt sand, and more fine sand is introduced the dust remover by the draught fan then, has increaseed the load of dust remover, has reduced effective induced air wind pressure, has reduced the sand drying ability. The invention provides a set of low-dust sand drying machine weight lock wind sand outlet bin, wherein a scheme is provided, the area of a peripheral opening of a weight lock wind plate is equal to the sectional area of flowing sand, and the flowing sand can form airtight sealing sand flow around the plate. Therefore, no wind enters from the sand outlet, the sand bin is reduced, the induced wind pressure is not weakened at the position, the induced wind capacity of the induced draft fan is improved, and further, the sand drying capacity is improved.
3. In a traditional sand outlet bin, sand is raised and dried in a dryer, so that a lot of sand dust and fine sand can be generated, and the sand is discharged from an outlet of the sand dryer, is sucked into a dust remover by an induced draft fan to remove dust. In the traditional sand drying machine, the primary sedimentation of fine sand is not considered in a discharging bin, so that the fine sand in a dust remover is larger, and the requirement of a user cannot be met. The invention provides a set of low-dust sand dryer heavy hammer air locking sand outlet bin, wherein a scheme is provided, so that the air speed of a dust collecting part in the discharge bin is reduced to about 0.2 m/s, and fine sand is settled. The requirements of users are met.
