Vertical stirring and conveying structure

Abstract

According to the technical scheme, the vertical stirring and conveying structure is characterized in that the vertical stirring and conveying structure comprises a rack and a conical hopper, the bottom of the conical hopper communicates with a discharging opening, a stirring paddle is rotationally connected to the bottom of the interior of the conical hopper, and the stirring paddle is fixed to the outer portion of a vertical stirring shaft through a stirring paddle bolt; the vertical stirring shaft is in sealed connection with the conical hopper through a first sealing structure, and a first transition shaft is rotationally connected into the first angular contact ball bearing and the second angular contact ball bearing; according to the vertical stirring and conveying structure, the power assembly is adopted to drive the first self-cleaning screw on the first output shaft to rotate, drive the second self-cleaning screw fixed outside the second output shaft to rotate, and drive the second transition shaft and the first transition shaft to rotate, so that the operation capability is improved, the investment is reduced, and the injection of materials in the conical hopper is facilitated; and a bridging phenomenon is not easy to occur.

Description

technical field [0001] The invention relates to the field of conveying devices, in particular to a vertical stirring conveying structure. Background technique [0002] In some common screw conveyors, since the shape of the hopper is usually a cone with a large upper and a small lower, the wall surface has a slope, and the cross-sectional area becomes smaller as it goes downward, so it is suitable for powders with high compressibility and adhesion. In other words, the bridging phenomenon in which the powder or granule does not fall locally or as a whole, or the rat-hole phenomenon in which only the material in the middle part falls is likely to occur. Because the hopper is connected and fixed on the horizontal screw conveying pipeline, when the feeding screw in the screw conveying pipeline advances, the material in the hopper tends to accumulate at the bottom, and due to the shape limitation of the hopper, the gap between the hopper and the screw conveying pipeline is caused....

Problems solved by technology

[0003] In order to overcome the hardening of materials, two sets of independent agitators are usually used at present, or ball-type buckets are used, but the disadvantages are obvious. If it is necessary to add stirring paddles and electric motors for driving the paddles on the top hopper cover, clean the materials above them. It is necessary to ensure the space for pulling up the stirring paddle, and the hopper cover with the stirring motor and paddle fixed must be pulled up, which is inconvenient for cleaning, resulting in high manufacturing cost and maintenance cost, so the traditional design idea needs to be improved
