[0051] When the filtering bucket 2 is pulled vertically upward, the filtering bucket 2 is taken down, the filtering bucket 2 is turned over, so that the second vertical cylinder 55 faces downward, and then the filter screen 56 in the transition cylinder 54 is washed by water from the first vertical cylinder 53, when the filter screen 56 is washed by water, because the tension spring 60 is arranged, the filter screen 56 is shaken, the elastic force of the tension spring 60 is smaller than the thrust force brought to the filter screen 56 by washing the filter screen 56 by water, when the filter screen 56 is washed by water, the water is intermittently washed, the impurities filtered out by the filter screen 56 are shaken off to the second vertical cylinder 55, and then the impurities fall out of the second vertical cylinder 55, one side surface of the second blocking ring 58 close to the first blocking ring 57 is an inclined surface, through the inclined surface on the second blocking ring 58, the situation that the impurities stay on the second blocking ring 58 can be reduced.

[0052] One circular groove 3 is equipped with two filter barrels 2, one of which is a standby, and during the process of cleaning the filter screen 56 in the filter barrel 2, the bottom end of the first vertical cylinder 53 in the standby filter barrel 2 can be passed through the circular groove 3, and the standby filter barrel 2 is driven vertically up and down by the driving member, at this time, the material is poured into the standby filter barrel 2, and the material is filtered through the standby filter barrel 2, at this time, when the filter barrel 2 is cleaned, the standby filter barrel 2 can continue to filter the material, which is simple and convenient to use.

[0053] In the use of the above-mentioned embodiment 1, the filter barrel 2 is vertically moved up and down by the driving member, at this time, the material is poured into the filter barrel 2, and the material can be filtered through the filter barrel 2, and the filtered material falls into the reaction barrel 1, when the filter barrel 2 is vertically moved by the driving member, the stirring group is driven by the driving member to stir the material in the reaction barrel 1, when the filter barrel 2 needs to be cleaned, it only needs to be pulled vertically upward until the filter barrel 2 is separated from the driving member and the circular groove 3, and the work of the driving member does not need to be stopped, at this time, the driving member can continue to drive the stirring group to stir the material in the reaction barrel 1.

[0054] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application belong to the scope of the claims of the present application and their equivalent technologies, the present application also intends to include these modifications and variations.
