The utility model discloses a static emulsification integrated device for M-type emulsion explosives. The static emulsification integrated device is formed by connecting and combining a water phase tank (12), an oil phase tank (13), a water phase delivery pump (14), an oil phase delivery pump (15), two mass flowmeters (16), a venturi tube (17) and a multi-stage jet flow static emulsifier (G), the multi-stage jet flow static emulsifier (G) is formed by combining an SK type static mixing pipe (1), an SK type static mixing unit (2), a first jet flow perforated plate (3), a jet flow emulsifying pipe (4), a forward spiral blade (5), a second jet flow perforated plate (6), a diaphragm type pressure gauge (7), a reverse spiral blade (8), an SV type uniform emulsion mixing pipe (9), an SV type uniform emulsion mixing unit (10) and a pressure relief pipe (11). The device disclosed by the utility model integrates SK type static mixing, multi-stage jet emulsification and SV type uniform emulsion mixing, and has the characteristics of good emulsification effect, high productivity, stable product quality, constant working pressure, high production line safety and excellent product performance index.

The invention discloses an anti-shaking storage bottle structure design method and an anti-shaking storage bottle structure.The anti-shaking storage bottle structure design method specifically comprises the following steps that a storage bottle three-dimensional model is established; performing structural simulation analysis on the three-dimensional model of the storage bottle to obtain structural stress distribution; performing fluid simulation analysis on the three-dimensional model of the storage bottle to obtain fluid motion parameters; and determining the storage bottle structure according to the structural stress distribution and the fluid motion parameters. According to the method, rapid optimization design of the storage bottle structure can be achieved, and high-cost physical tests in a traditional design method can be avoided.

The utility model provides a kind of extrusion screw structure of film blowing machine, including base, the top of base is fixedly installed with conveying cylinder, the top of conveying cylinder is equipped with the feeding hopper being communicated therewith, the discharge port of conveying cylinder is fixedly installed with filter box, the discharge port of filter box is fixedly installed with discharge nozzle, the inside of filter box is provided with filter assembly, the top of base is fixedly installed with motor located conveying cylinder one end, the bottom of filter box is detachably installed with pollution collection box. The filter assembly of being set, make reciprocating rod when being driven to rotate by conveying screw, reciprocating block drives reciprocating rod and its one end scraping strip to reciprocate sliding simultaneously, so that scraping strip removes impurity on the surface of filter plate, effectively reduce the blockage of filter plate due to impurity accumulation, ensure the smooth flow of plastic melt, maintain the stable working pressure of film blowing machine, to improve the quality and stability of blown film.
