Mixer

Abstract

The invention relates to a feeding and mixing device, which includes a feeding mechanism, a mixing mechanism, a discharging mechanism and a driving motor. The feeding mechanism includes a feeding bin, and the discharging mechanism includes a discharging bin and a discharge The mixing mechanism includes a horizontally arranged mixing bin and a mixing screw located in the mixing bin. The mixing bin and the discharging bin are coaxially assembled and detachably connected to each other. The mixing screw and the discharging The screws are coaxially installed and connected with each other by mortise and tenon. The driving end of the mixing screw and the output shaft of the driving motor are connected through a coupling. The feeding bin and the mixing bin are integrally formed. The longitudinal section of the closing part of the feeding bin is Asymmetrical structure of right-angled trapezoid. The invention can effectively prevent the bridging phenomenon in the powder conveying process and avoid the influence of the powder bridging on continuous production; the utility model realizes the synchronous drive of the arch-breaking stirring mechanism, the mixing screw and the discharging screw through a driving motor , can save energy consumption.

Description

technical field [0001] The invention relates to a dosing and mixing device for powder production, belonging to the technical field of powder processing equipment. Background technique [0002] In the prior art, the powder is prone to powder bridging during the feeding process, and a vibrating device is often used to avoid and break the bridging, but the vibrating method requires repeated knocking on the feeding device, which affects the strength and service life of the feeder, and the noise is relatively high. Larger, and sometimes the more serious the vibration and bridging, there is another way to prevent bridging in the prior art, that is, the motor on the upper part of the feeder drives the vertical stirring mechanism, but the stirring paddle of the vertical stirring mechanism only adjusts to the horizontal direction where it is located. The bridging within the range of the cross-section works, but the effect on the bridging outside the cross-section is weak, and the eff...

[0002] In the prior art, the powder is prone to powder bridging during the feeding process, and a vibrating device is often used to avoid and break the bridging, but the vibrating method requires repeated knocking on the feeding device, which affects the strength and service life of the feeder, and the noise is relatively high. Larger, and sometimes the more serious the vibration and bridging, there is another way to prevent bridging in the prior art, that is, the motor on the upper part of the feeder drives the vertical stirring mechanism, but the stirring paddle of the vertical stirring mechanism only adjusts to the horizontal direction where it is located. The bridging within the range of the cross-section works, but the effect on the bridging outside the cross-section is weak, and the effect of breaking the bridging is not good
