Detailed Description
In order to facilitate understanding of the present invention, the present invention will be described more fully and specifically with reference to the accompanying drawings and preferred embodiments, but the scope of the present invention is not limited to the following specific embodiments.
Example (b):
as shown in fig. 1 to fig. 3, the cleaning device for removing agglomerates in a mixer of the present embodiment includes a scraper 1, the scraper 1 is fixed on a frame of the mixer through a supporting device 2, and penetrates into a mixing barrel 3 from the top, and is arranged along the axial direction of the mixing barrel 3, when the mixing barrel 3 of the mixer rotates, the scraper 1 can scrape agglomerates adhered to the inner wall of the mixer. In addition, be equipped with a plurality of compressed air holes 11 that are used for spraying high-pressure gas on scraper 1, each compressed air hole 11 evenly lays along scraper 1's axial, forms the even stable condition that strikes the efflux and destroy the material and cohere the blocking, can not only prevent in real time that the material from cohering the blocking in material mixing process, has further optimized clear material effect, can also clear up when maintaining under 3 lines of blending bin.
This embodiment directly sets up compression gas pocket 11 on scraper 1, and compressed gas can increase the inside air gap of caking of treating scraping off, has reduced the hardness and the viscidity of caking, not only makes scraping off the caking that scraper 1 can be easier, can also reduce blending drum 3 and rotate the effort of in-process caking to strutting arrangement 2, prevents strutting arrangement 2 deformation, and has reduced the equipment consumption.
In this embodiment, the compressed air hole 11 is located in front of the blade of the scraper 1 along the rolling direction of the mixing barrel 3, and removes the material before the blade of the scraper 1. During working, compressed gas can prevent materials from caking on one hand, and on the other hand, an air knife is formed, so that a part of a caking layer adhered to the inner wall of the mixing barrel 3 is blown off by the air knife, air gaps of the remaining caking layer are increased under the action of the compressed gas, the viscosity among particles is reduced, the hardness is reduced, and the residual caking layer can be easily and thoroughly removed by the later scraper 1. The combined action of the compressed gas and the scraper 1 can not only prevent the respective pressing action when the compressed gas and the scraper are independently arranged, but also thoroughly break away the caking layer, reduce the resistance of the mixing barrel 3 in the rotating process and the supporting device 2, and improve the clearing effect.
