Internal circulation carding and drying integrated papermaking machine

Abstract

The present invention provides an integrated carding and drying papermaking machine capable of internal circulation, which relates to the technical field of papermaking machines. The supporting seat is a frame structure, and an electromagnetic block is fixedly connected to the top of the supporting seat. There are two electromagnetic blocks in total, which solves the problem that when drying pulp, gas is mostly extracted from the outside and heated before being blown to the pulp to dry it. However, due to the frequent extraction of air from the outside, it is difficult to effectively filter impurities in the air, and heating also causes waste of resources, which has limitations. By starting the dryer, a return pipe is used to quickly extract part of the gas blown out by the dryer and the gas remaining in the base, and the filter element arranged in the return pipe is used to filter the residual moisture in the recovered gas and then re-supply it into the interior of the dryer and blown into the interior of the base. The liquid filtered by the filter element can also be quickly discharged through the drain pipe for release.

[0008] Furthermore, the flow concentrator is a frustum-shaped structure that is thick at the top and thin at the bottom, and is used to converge liquid. The bottom end of the flow concentrator is connected to a discharge pipe through a spring, and the discharge pipe and the flow concentrator together constitute a flow concentrating structure.

[0009] Furthermore, a filter element is installed on the outside of the return pipe, which is used to filter the liquid in the hot air.

When the moving frame slides, it can synchronously drive the sorting claws fixedly connected to its bottom end surface to slide along the bottom plate, and the pulp on the bottom plate can be quickly sorted by the movement of the sorting claws. By quickly sorting the fibers in the pulp, the subsequent production effect of balanced paper can be effectively improved.

[0018] 3. When the paper needs to be dried after the paper is sorted, the dryer installed in the base can be started to heat the air and blow it to the pulp on the bottom plate to quickly dry it. During the drying process, the dryer can be started to use the return pipe to quickly extract part of the gas blown out by the dryer and the gas remaining in the base, and the residual moisture in the recovered gas can be filtered by the filter element set in the return pipe and then re-supplied into the dryer and blown into the base. The liquid filtered by the filter element can also be quickly discharged through the drain pipe for release. When the drying is completed, the traction push rod can be started to pull the flow collecting seat to the left and unfold it. At this time, the motor B is started to drive the bearing seat to flip through the meshing transmission of gear A and gear B to quickly flip the pulp on the bottom plate and drop it onto the conveyor belt.
