Technical Field

[0001] The utility model relates to the technical field of feeding screw conveyors, in particular to a feeding screw conveyor for sizing agent production with a anti-blocking function. Background Technique

[0002] The sizing agent is a papermaking additive, mainly divided into internal sizing and surface sizing. During the production process of the sizing agent, it needs to be transported by a feeding screw conveyor. However, the existing feeding screw conveyors are prone to material blockage, which is not conducive to the transportation of materials, and causes damage to the shaft and blades of the feeding screw conveyor, affecting the production efficiency of the sizing agent.

[0003] In the prior art, the publication number CN217200331U is proposed. The technical solution disclosed in this patent document is as follows: an anti-blocking screw conveyor, including a base, a conveying pipe is installed on the base, and an auger shaft matched with it is installed in the conveying pipe; above one end of the conveying pipe, a filtering chamber and a stirring chamber are connected. After the material is filtered in the filtering chamber, the lumpy or sticky material can enter the stirring chamber to be crushed and then fall into the conveying pipe for transportation. A lifting baffle is installed between the filtering chamber and the stirring chamber, which can be lifted after filtering to make the material to be stirred fall into the stirring chamber; the utility model can prevent the lumpy or sticky material from not being transported normally and blocking the device.

[0004] The above technical solution filters out the lumpy or sticky material through the first filter screen, and the first filter screen is inclined. The passing material is very easy to slide into the stirring chamber before being filtered, resulting in poor filtering effect, thereby increasing the burden of crushing and stirring inside the stirring chamber and consuming electricity.
