The present disclosure relates to a counter-direction differential screw kneading device, a continuous kneading machine, and a material preparation system. A screw mechanism comprises a central screw and a peripheral screw which are in a counter-direction differential fit. Central blades of the central screw are each provided with a central blade concave surface on the side facing a peripheral blade and along the direction of rotation of the central blade. Peripheral blades of the peripheral screw are each provided with a peripheral blade convex surface on the side facing a central blade and along the direction of rotation of the peripheral blade. The central blade concave surface and the peripheral blade convex surface are in an enveloping fit. Each of the central blade concave surface and the peripheral blade convex surface is provided with a material kneading section. There is a kneading gap e between the material kneading sections of the two surfaces. From the start to the end of engagement of the material kneading sections of the two surfaces, the kneading gap e remains constant. In the present disclosure, when the material kneading sections of the central screw and the peripheral screw perform kneading on the material in an enveloping manner, the kneading gap e remains constant, ensuring forward conveyance of the material while enabling the material to be thoroughly kneaded and mixed, thereby improving the mixing effect of the material.

Disclosed in the present invention are a liquid dispersion structure assembly and a powder-liquid mixing device. A partition plate is arranged inside a housing of a dispersion stator of the liquid dispersion structure assembly; by means of the partition plate, an inner cavity of the housing is divided into a lower-layer dispersion area and an upper-layer dispersion area; the dispersion stator is provided with a lower-layer matching structure and an upper-layer matching structure in the lower-layer dispersion area and the upper-layer dispersion area respectively; a lower-layer rotor is arranged in the lower-layer dispersion area, and rotationally matches the lower-layer matching structure of the dispersion stator; and an upper-layer rotor is arranged in the upper-layer dispersion area, and rotationally matches the upper-layer matching structure of the dispersion stator. In the present invention, the dispersion stator having a double-layer structure is configured for simultaneously matching the lower-layer rotor and the upper-layer rotor so as to achieve layered dispersion, such that the flow resistance is smaller, the flow is smoother, the flow loss is smaller, the overall structure is more compact, and thus the flow path of liquid in the dispersion area is shorter and smoother.

Disclosed in the present invention are a multilayer series-connected axial-flow type paste dispersing device and a powder-liquid mixing device. Dispersing rotors and dispersing stators in a plurality of layers are provided in a housing, the dispersing rotors and the dispersing stators being stacked in the axial direction; the dispersing rotors each have a thick inner part and a thin outer part, while the dispersing stators each have a thick outer part and a thin inner part; rotor dispersing rings and stator dispersing rings are alternately arranged, the rotor dispersing rings extending into rotor ring accommodating slots, and the stator dispersing rings extending into stator ring accommodating slots. In the present invention, flow pass-through holes of the dispersing rotors and of the dispersing stators are communicated in the axial direction; in a dispersing structure, a liquid paste simply needs to flow in an axial flow channel from bottom to top without being diverted, thereby realizing a short paste flow distance, low flow resistance, smooth flowing, low flow loss, high efficiency, and low energy consumption; in addition, when the paste flows through the flow pass-through holes in the axial direction from bottom to top, flow rates and velocities at each portion of the flow pass-through holes are kept consistent, thereby ensuring the consistent dispersing effect of dispersing areas, realizing more uniform dispersion and the better dispersing effect, and more helping to improve the energy utilization rate.

The present invention relates to a bag clamping apparatus, comprising: a first pressing ring provided at a mouth portion of a material tank and provided with a first working wall; a second pressing ring movably sleeved on an outer wall of the material tank and provided with a second working wall used to match with the first working wall to tightly press a bulk bag; a circular pressing plate close to or distant from the material tank, a lower portion of the pressing plate being able to match with an inner wall of the material tank so as to tightly press the bulk bag, and an upper portion of the pressing plate matching with the first pressing ring so as to tightly press the bulk bag. When transferring a material from the bulk bag to the material tank, the pressing plate abuts against the material tank, the second pressing ring abuts against the first pressing ring, and a bottom edge of the bulk bag sequentially wraps over gaps between the lower portion of the pressing plate and the material tank, between the upper portion of the pressing plate and the first pressing ring, and between the first working wall and the second working wall, and is tightly pressed. The present invention also provides a sealing structure, a bag opening machine, and a bag opening method. The sealing structure and the bag clamping apparatus provided in the present invention can perform sealing of two layers of packaging simultaneously, so that continuous sealing and discharging between adjacent bulk bags for feeding is implemented.
