Description

Technical Field

[0001] The invention relates to the technical field of sintering, and in particular to an online material cleaning device and method for a drum mixer. Background Art

[0002] Quicklime is added to the sintering raw materials due to process requirements. During the process of adding water and wetting, the viscosity of the mixture increases, which will cause the material to stick to the inner wall of the cylinder and form a ring, increase the weight of the cylinder and the load on the motor, reduce the internal space of the cylinder, shorten the mixing time, and affect the granulation effect.

[0003] There are two traditional ways to clean sticky materials: offline cleaning and online cleaning. Offline cleaning mainly uses manual regular shutdown cleaning. Online cleaning has the form of "fixed beam + scraper". The fixed beam fixes the scraper, and the scraper can scrape the sticky materials on the cylinder wall. There is also the form of "flexible suspension + cleaning rod". The mixed material adhering to the cylinder wall causes the flexible suspension device to vibrate, and the cleaning rod impacts the sticky material; the cleaning rod uses the resistance generated by the mixed material adhering to the cylinder wall as the rotational power to produce a rolling and scraping effect on the sticky material.

[0004] After searching the prior art, the announcement number CN109225049A discloses an electric scraper device for a sintered drum mixer. It includes a front transmission assembly, a cage scraper assembly and a rear transmission assembly. The cage scraper assembly is fixedly mounted to the front support and the rear support of the drum mixer through the connecting flange of the front transmission assembly and the connecting flange of the rear transmission assembly respectively. The adjacent scrapers of the cage scraper assembly are arranged symmetrically with no gap, that is, there is an overlapping area between each other. The length direction center of each scraper is arranged in a positive spiral or a reverse spiral arrangement to both sides; by adjusting the installation flange positions of the front transmission assembly and the rear transmission assembly, the gap between the front scraper and the fixed scraper in the front transmission assembly, the scraper in the cage scraper assembly, and the rear scraper in the rear transmission assembly and the barrel wall of the drum mixer can be adjusted.

[0005] The adjacent scrapers of the through-type scraper assembly in the reference document are arranged in a gapless symmetrical staggered arrangement, that is, they are arranged in a forward and reverse bidirectional spiral from the center of the scraper length direction to both sides. When working, only two scrapers enter the scraping position at the same time. Therefore, the present invention not only reduces the scraping resistance, but also realizes full-length cleaning without dead angles, and can achieve the purpose of comprehensive cleaning. The present invention can achieve continuous, energy-saving, stable and safe use effects through a simple transmission structure and reasonable arrangement of scraper positions and angles, combined with a reasonable speed ratio. However, external power is required for transmission. Summary of the invention

[0006] The object of the present invention is to provide an online material cleaning device and method for a drum mixer to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solution: it includes a rotating barrel, support mechanisms are provided on both sides of the rotating barrel, a rotating shaft is provided inside the rotating barrel, eccentric wheel devices are provided on both sides of the rotating shaft, a plurality of cleaning rods are movably connected to the surface of the rotating shaft, and the plurality of cleaning rods are evenly distributed on the surface of the rotating shaft, a gear ring is provided on the outer surface of the rotating barrel, a driving wheel is meshingly connected to the gear ring, a driving motor is provided at one end of the driving wheel, and a supporting base is provided on the outer side of the eccentric wheel device.

[0008] Preferably, the eccentric wheel device comprises an outer bearing, the interior of the outer bearing is connected to an inner bearing via an eccentric wheel, and the center of the inner bearing deviates from the center of the outer bearing.

[0009] Preferably, the rotating shaft and the cleaning rod realize the swinging motion through an eccentric wheel.

[0010] Preferably, the position of the support base can be moved to adjust the distance between the cleaning rod and the inner wall of the rotating barrel.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: when the rotating barrel rotates, the sticky material on the inner wall can drive the rotating shaft and the cleaning rod to rotate, so that the cleaning rod swings under the support of the eccentric wheel device, and periodically contacts and collides with the sticky material on the inner wall of the rotating barrel. Bearings are provided at both ends of the rotating shaft. It is always in a rotating state during the working process, and the blanks fall off during the rotation process, avoiding the accumulation of materials. During the operation, the eccentric wheel device can realize the swinging action of the rotating shaft, which impacts the sticky material. The support base can set the minimum distance from the cleaning device to the inner wall of the barrel, avoiding the impact of the cleaning rod on the rotating shaft on the liner. When the sticky material on the inner wall of the rotating barrel contacts the cleaning rod, it can drive the cleaning rod and the rotating shaft to rotate. BRIEF DESCRIPTION OF THE DRAWINGS
