Detailed Description
The clear stifled device in this embodiment discloses of feed bin is particularly useful for the clear stifled of powder feed bin.
As shown in fig. 1 and 2, the blockage removing device mainly comprises a driving motor 1, a revolving body 2 and a scraper 3.
The revolving body 2 is a ball bearing, the inner diameter of the inner ring 21 of the revolving body is matched with the outer diameter of the outlet of the conical section at the lower part of the storage bin, the upper end faces of the inner ring 21 and the outer ring 22 are flush, the lower end face of the inner ring 21 extends out of the lower end face of the outer ring 22, the extending section of the inner ring 21 is connected with a belt wheel DL, and the outer ring 22 is horizontally suspended on the outer wall of the conical section through a suspender.
The solid of revolution 2 arranges outside the feed opening of feed bin, and its axis of revolution is the axial direction line of feed bin, and scraper 3 has the multiunit, is on a parallel with the inner wall setting of feed bin lower part conic section, and the lower extreme of scraper 3 is connected fixedly with the upper end of solid of revolution 2, and when driving motor 1 drive solid of revolution 2 made rotary motion, scraper 3 was encircleed the material and is carried out the broken arch and clear stifled along with solid of revolution 2 is rotatory to the knot of conic section inner wall.
The driving motor 1 is a variable frequency motor capable of rotating forward and backward, an output shaft of the driving motor is connected with a belt wheel DL, and the two belt wheels are driven by a belt PD.
The cross section of the scraper 3 is triangular, and the blade points are positioned at the two side waists, so that the scraper can break the arch and clear the blockage when rotating forwards and backwards; the multiple groups of scrapers are uniformly distributed along the circumferential direction and are parallel to the inner wall of the conical section, the length of each scraper is preferably 0.75 time of the length of the conical section of the storage bin, the distance between each scraper and the inner wall of the conical section is not more than 5mm, the scraper can break the boundary of an easily arching area of materials, and efficient blockage removal is realized.
In the embodiment, three groups of scrapers 3 are uniformly distributed along the circumferential direction of the inner wall of the conical section, and the upper ends of the scrapers 3 are connected and limited through a horizontal metal ring 4 so as to ensure the stability of the scrapers in the rotating process; the lower end of the scraper 3 and the inner wall of the upper end of the inner ring 21 of the revolving body 2 and the upper end of the scraper 3 and the horizontal metal ring 4 are respectively fixed through bolts.
