Detailed Description
The invention will be further described with reference to the following examples (drawings):
as shown in fig. 1 and 2, the anti-swing support device for the bottom of the vertical stirring apparatus of the present invention comprises a support ring 4, a plurality of lifting lugs 5 fixed on the outer ring surface of the support ring in an evenly distributed manner, a lubrication guide pipe 6 welded on the outer ring surface of the support ring 4 through a fixed reinforcing rib 7 and communicated with an oil guide hole processed on the support ring, and an annular fixed block 1 installed in the support ring 4 through an evenly distributed slide block 2 and a support connecting rod 3 connected with the slide block in a sliding fit manner with an annular guide groove.
Four supporting connecting rods 3 extending horizontally to the periphery are uniformly distributed on the outer ring surface of the annular fixing block 1, and the extending end of each supporting connecting rod is respectively connected with a sliding block 2 in sliding fit with the inner ring surface of the supporting ring 4 (the number of the sliding blocks 2 is 4-12 according to the difference between the diameter of the stirrer and the conveyed material).
The surface of the sliding block 2 is hardened, the hardness is HB 200-800, and the lubricating flow guide pipe 6 provides a lubricating agent for the annular guide groove of the support ring 4, so that the friction between the sliding block 2 and the inner wall of the support ring 4 is reduced.
The invention is suitable for equipment for stirring materials with the viscosity of 500-3500 Pa.s. The cross-sectional shape of the support connecting rod 3 may be circular, polygonal, elliptical, or the like.
As shown in figure 3, the device of the invention is arranged below the stirrer and plays a role in preventing the scraping plate from colliding with the inner cylinder body and pushing materials. When the stirrer operates, the slider 2 slides in a limited circumferential area through strictly controlling the gap between the slider 2 and the inner wall of the support ring 4, and the gap ensures that the scraping plate of the stirrer cannot scrape the inner wall of the inner cylinder; the front end of the sliding block 2 is provided with a slope with a certain angle, so that the material can be pushed downwards conveniently when the equipment runs. The lubricating guide pipe 6 is added with the lubricant at regular time, so that the friction between the sliding block 2 and the inner wall of the support ring 4 is reduced. During the operation of the equipment, although lubricant exists between the sliding block 2 and the supporting ring 4, the phenomenon of hard friction caused by uneven feeding and the like is difficult to avoid, so the sliding block 2 is subjected to special hardening treatment, and the hardness of the sliding block is higher than that of the supporting ring 4. After long-time operation, if the glue solution is not uniformly mixed and abnormal sound occurs during operation, after other factors are eliminated through detection, if the inner wall of the support ring 4 is abraded, the lower cylinder body of the support ring is timely detached, the support ring is replaced, and long-time parking maintenance time caused by abrasion of the scraper can be effectively shortened.
