A control method for a washing machine and a washing machine. The washing machine includes: a water tank having a circulating filter pipeline, a water inlet end and a water outlet. A circulation pump and a filtering device are arranged on the water tank. A filtering device includes a filtering cavity. A filtering mechanism is rotatably arranged inside the filtering cavity. The control method includes: delivering clothes treatment agent into the water tank; turning on the circulation pump to circulate the water in the water tank through the filtering device; controlling the filtering mechanism to rotate in the filtering cavity at a first speed to dissolve the clothing treatment agent in the water. The filtering device of the present disclosure itself has the function of removing lint in the water, after the clothes treatment agent is delivered, it can also rotate through the filtering mechanism to stir the water flow.

The present relates to an oil sands slurry filter cartridge that includes first and second sets of filter rings that are alternately arranged to form a stack with an interior passage, and where the filter rings are spaced apart to define a filtration gap in between adjacent pairs of filter rings. The filter cartridge can be configured such that the first and second sets of filter rings are rotatable with respect to each other to facilitate self-cleaning. The filter cartridge can be configured such that each filter ring has a wedge shaped profile tapering inwardly toward the passage for enhanced filtration functionality.

A laminated spiral dewatering equipment, including a filtration cavity, a spiral shaft, a driving device and multiple supporting plates. The supporting plates are configured to support and position the filtration cavity, the spiral shaft and the driving device. The spiral shaft is penetratedly arranged in the filtration cavity. The filtration cavity includes a first closed ring piece group and a second closed ring piece group. A primary driving rod of the driving device is arranged above the filtration cavity, and is configured to drive an upper end of the first closed ring piece group to circumferentially reciprocate, and a lower end of the first closed ring piece group to perform a up-down reciprocating linear motion.
