Abstract: The present disclosure discloses a wireless building block type splicing fan comprises a fan body. A splicing tenon and a connector plug are disposed on one side of the fan body, and a splicing mortise and a connector socket corresponding to the splicing tenon and the connector plug each other are disposed on the other side of the fan body. A positioning buckle is disposed in the splicing mortise. According to the wireless building block type splicing fan of the present disclosure, when a plurality of fan bodies are spliced, the splicing tenon of one of the two adjacent fan bodies is inserted into the splicing mortise of the other of is the two adjacent fan bodies. After being inserted, the positioning buckle limits and secures the splicing tenon, and at the same time, the connector plug is inserted into the connector socket for electrical connection.

Abstract: A fan with multiple light rings according to the present disclosure, by means of the setting of the specific structure of the lower fan frame cover, the light guide frame, and the upper fan frame cover, with the shading cover and the outer light source ring, using a light guide frame to guide the light emitted by the outer light source ring, which can form three light rings on the inner side, outer side and upper side of the fan frame.

Abstract: A filter press includes a frame, a hydraulic system for compressing and releasing filter plates, the filter plates, a filter chamber, a feed pump, a high-pressure clean water pump, a control system, a rotating plate, a cake removal knife, a squeeze disc, a squeeze disc sleeve, a drive shaft, a brake, a left pull rod, a right pull rod, a pull rod disc, a connector and clutches. The filter cake in the entire filter press can be removed without opening the filter plates in sequence. The filter cake washing is carried out in an enclosed room in a normal direction and a reverse direction, which can not only maintain the dryness and cleanness of the working environment, but also can effectively collect, process treat and recycle the washing water, thus achieving the zero discharge of waste water to meet the environmental requirements at a low cost.

Abstract: A fast-speed laser scoring method is provided, in which a set of related laser scoring device is used to simultaneously score lines on the upper surface and the lower surface of an oriented silicon steel strip, which is being fed and traveling forwards on a production line, with high-focalized continuous wave laser beam; the lines scored on the upper surface and the lines scored on the lower surface have the same space between every two adjacent scored lines but are staggered each other in order to reduce iron loss evenly. The space between every two adjacent scored lines on the same surface is 6-12 mm, laser power is 1000-3000 W and scanning speed is 100-400 m/min. The machining rate of the scoring method and device attains 1.5-2 times the one of conventional scoring methods which can not simultaneously score the upper and lower surfaces of a steel strip at a time. The lines scored on a steel strip by the method can reduce iron loss of the strip by 10-16%.
