The thickening agent is one of common chemical auxiliary agents and is widely applied to the fields of adhesives, printing ink, coatings and the like. The finished product of the thickening agent needs to be filtered in the production process so as to filter impurities, slag and the like in the finished product and improve the using effect.

The existing discharging and filtering device for the thickening agent generally needs to be stopped for treatment because slag after being filtered cannot be discharged timely and effectively. For example, chinese patent CN 203750277U discloses a thickener discharging filter, which is characterized in that when in use, the filter residue is attached to the outside of the filter basket, and is not easy to be separated and discharged, and because the filter basket is a device with uniform filtering holes as a whole, because it is impossible to block the filter residue at the same time by each mesh, the filter residue can not be effectively separated from the filter basket by blowing compressed air, the actual using effect is poor, and the filter residue attached to the filter basket needs to be stopped and cleaned regularly. This intermittent operation significantly reduces production efficiency.

In order to improve the automatic slag removal performance of the filter and avoid the problem of low production efficiency caused by intermittent production, the industry improves the structure of the existing thickener filter. For example, chinese patent CN 208878019U discloses a thickener discharging filter, which is provided with a slag hole on a filter box between a filter cylinder and a feeding bin, wherein the thickener is sequentially separated through filter holes on a filter screen and the filter cylinder by the rotation of the filter cylinder, and simultaneously, filter residue is automatically separated through the slag hole and discharged out of the filter box under the action of centrifugal force. Because the slag notch is located the top periphery of filtering the drum, the filter residue can be beaten on filtering drum filter screen all around under the effect of centrifugal force for the filter residue more is difficult to break away from on the filter screen, consequently, this filter is in the in-service use process, and the volume of actually slagging tap is less automatically, and most filter residue card is difficult to get rid of on the filter screen, and then influences the filtration of follow-up thickener, can not realize purported result of use or service function.
