Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Fig. 1-4 show a floccule cutter for a water used in a ship desulfurization system, which is used on a water pumping pipe for pumping seawater. The water pumping pipe comprises a mounting flange 1, wherein a plurality of mounting screw holes are formed in the mounting flange, and a cutter is fixed on a water inlet port of a water pumping pipe through a bolt in the mounting screw holes. The diameter of mounting flange matches with the diameter of drinking-water pipe and suits, makes the utility model discloses the cutterbar is installed at the mouth of pipe, during the use, the sea water passes through earlier before inhaling the drinking-water pipe the utility model discloses the cutterbar can cut following flocculus such as the inspiratory pasture and water of sea water.

A plurality of blades 4 are rotatably arranged in the mounting flange and are connected to the mounting flange through a central bearing 2; the central bearing is coaxially sleeved inside the mounting flange; the central bearing comprises a bearing outer ring and a bearing inner ring 6; the bearing outer ring is fixedly connected to the inside of the mounting flange, and a plurality of balls 7 are clamped between the bearing outer ring and the bearing inner ring; the bearing inner ring is rotationally connected with the bearing outer ring through balls; a plurality of blades are fixedly mounted on the bearing inner ring.

Through the characteristic that the bearing inner ring and the bearing outer ring can rotate relatively, the bearing outer ring is fixed on the mounting flange, so that the whole central bearing can be fixed on the mounting flange in a welding mode. The blade is fixed on the bearing inner ring, so that the blade can rotate relative to the mounting flange and the bearing outer ring.

Since the plurality of blades are all arranged on the circumference of the bearing inner ring, the plurality of blades are arranged in a radial arrangement from the outside to the inside. Every blade all rotates certain angle and is fixed along its self axis, and the angle of rotation is 5 ~ 60. The blade rotation angle makes the knife face of blade inclined, is similar to the flabellum of fan, and when the pipe that draws water was taken out water under the water pump effect, the rivers that flow impact will exert the effort to the blade on inclined knife face, overcome the resistance, make the blade drive the bearing inner ring and rotate, and the blade that rotates can cut up the floccule that smugglies was smugglied in the sea water.

A plurality of clamping grooves are formed in the inner wall of the bearing inner ring corresponding to the plurality of blades, and the roots of the blades are correspondingly clamped in the clamping grooves. The blade can be directly clamped and fixed in the clamping groove in a fixing mode, and the blade can be fixed through the cover plate so as to be detachable.
