Description

Pulp mixing system Technical Field The application relates to the technical field of pulp mixing, in particular to a pulp mixing system. Background In the process of producing disposable paper tableware, functional assistants such as waterproof agent, oil-proof agent and the like are generally added into a base material, so that the produced disposable paper tableware has corresponding functions. In the production, the base material is dissolved by adding water to form semi-finished paper pulp, then the semi-finished paper pulp is conveyed to a mixing tank to be fully stirred and mixed with various auxiliary agents, and finally the semi-finished paper pulp is conveyed to a forming workshop to be subjected to hot press forming. However, the current production workshop has a large demand for mixed pulp, and after a single mixing tank finishes the pulp preparation of a batch of pulp and conveys the pulp to a forming workshop, the single mixing tank must wait for the completion of the use of the batch of pulp and the emptying of the mixing tank, so that the preparation of the next batch of pulp can be carried out, during the period, the feeding of the downstream forming process is interrupted, and the machine needs to be stopped for waiting, thereby not only reducing the utilization rate of equipment and influencing the overall production efficiency.
