The invention discloses a special extruding and filtering device for biological product materials, which comprises an outer frame, a material containing disc and a transverse plate, the material containing disc is arranged outside the outer frame, the material containing disc is in sliding connection with one side of the outer frame, and the transverse plate is arranged at the bottom of the material containing disc; the stress plates are evenly installed on the inner wall of the material containing disc, the stress plates are elastic plates, and arc-shaped filter screens are installed on the stress plates; the invention discloses an extrusion plate and relates to the technical field of material extrusion and filtration equipment. The special extruding and filtering device for the biological product material achieves the purpose of improving the filtering efficiency, can avoid the problem that filtrate extruded from a biological material located at a relatively high position easily permeates into a material below to cause waste, improves the use safety degree, can conveniently observe the extruding and filtering force, and is convenient to use. Equipment damage caused by increase of extrusion force is avoided, the positions of the materials can be changed in the extrusion and filtration process, and it is guaranteed that the materials in different positions are extruded and filtered in a balanced mode.

The present application relates to the technical field of teaching management, and discloses a kind of artistic practice course's mixed teaching task collaborative allocation method and system, the method includes: the multi-source task sequence and teaching state data of target process are collected, and task chain is constructed based on execution constraint and dependency relationship. Available resources and role state are combined into state snapshot, according to the demand of first task, candidate role set is filtered, the role with minimum load is selected as allocation target and is set as load balancing anchor point, and cascaded successor task obtains collaborative allocation sequence. Continuously receive the attendance signal and completion signal of offline classroom and online platform, and are associated and bound according to timestamp and corresponding task node, to generate execution event track. According to the state transition mark in track, update node state, form collaborative allocation closed loop record;The present application can improve the efficiency of artistic practice course's mixed teaching task collaborative allocation.
