Description

Technical Field

[0001] The utility model relates to the technical field of phosphate impurity removal, in particular to an impurity removal device for phosphate production. Background Art

[0002] Existing phosphate impurity removal technologies mostly use impurities removal during stirring. However, this method is prone to the stirring rod colliding with hard objects during use, causing damage. For example, a Chinese patent discloses "an impurity removal device for phosphate production" with application number "CN201920912945.9". It uses a rotating rod to rotate, and the rotating rod drives the stirring rod to rotate, and the phosphate rotates with the stirring rod. During the rotation, the phosphate passes through the interception hole and continues to fall downward, while the impurities larger than the interception hole are intercepted and stay in the feed pipe. The phosphate passes through the screening hole and finally flows out from the discharge hole, thereby achieving the effect of impurity removal. However, screening while stirring can easily cause hard objects to collide with the stirring rod, causing damage. Utility Model Content

[0003] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide an impurity removal device for phosphate production. Phosphate is poured into a centrifugal rotating box from a feed hole through the cooperation of a rotating shaft and spiral blades. Due to the centrifugal force generated by the rotation, the phosphate is thrown onto the inner wall of the centrifugal rotating box. Through the cooperation of a breaking block and the spiral blades, the spiral blades have a spiral path, and an arc is provided on the breaking block. The breaking block effectively breaks up the clumped phosphate, facilitates subsequent screening, improves screening efficiency, and reduces the burden on the filter screen. Through the cooperation of the fine filter screen and the coarse filter screen, the aperture of the fine filter screen is smaller than that of the coarse filter screen, which prevents incomplete filtration of the coarse filter screen, improves the filtering effect, and improves the quality of the phosphate.
