AI Technical Summary

Technical Problem

In the existing technology, high-temperature resistant crepe paper pulp grinding devices are prone to frequent jamming and clogging problems due to excessive material feeding at one time.

Method used

The design employs an alternating intermittent feeding mechanism, which periodically opens and closes the feed inlet using a slide gate valve assembly. Combined with the structure of the annular grinding channel and the storage chamber, this ensures that the material is evenly distributed and enters the grinding channel in batches, avoiding blockages. Furthermore, it utilizes its own gravity and the inclined grinding surface to improve grinding efficiency.

Benefits of technology

It effectively reduces the possibility of grinding blockage, improves grinding efficiency and stability, simplifies the device structure, reduces power consumption, and forms a continuous closed-loop process of feeding, grinding, and storage.

Abstract

The invention discloses a high-temperature-resistant crepe paper pulp grinding device and a pulping method. The device comprises a pulping barrel, a grinding assembly and a gate valve assembly. The pulping barrel is provided with a feeding port, a grinding cavity and a storage cavity which are sequentially arranged in the vertical direction; the grinding assembly is arranged between the grinding cavity and the material storage cavity and defines an annular grinding channel, the two axial ends of the annular grinding channel are through and communicate with the grinding cavity and the material storage cavity correspondingly, and the material storage cavity is used for storing materials passing through the annular grinding channel; the at least two feeding holes are formed in the circumferential direction of the annular grinding channel at intervals; the gate valve assembly comprises a driving mechanism and at least two gate valve bodies, and the gate valve bodies correspond to the feeding ports in a one-to-one mode and are installed at the feeding ports in a sliding mode. And the driving mechanism is connected with each gate valve body and drives the at least two gate valve bodies to periodically alternate at the closing position and the opening position, so that at least one feeding port is in an opening state at any moment. According to the invention, the possibility of grinding blockage caused by excessive one-time blanking can be reduced.
