Agitating unit is used in biodegradable plastic film production

Technical Field

The utility model relates to a agitating unit is used in biodegradable plastic film production belongs to biodegradable plastic film preparation facilities field.

Background

The biodegradable film is a film which can be degraded by the action of microorganisms under natural environment conditions, after microorganisms such as bacteria, fungi and actinomycetes erode a plastic film, polymer components are hydrolyzed, ionized or protonated due to the growth of cells and are mechanically destroyed and split into oligomer fragments, and enzymes secreted by the fungi or the bacteria decompose or oxidize and degrade water-soluble polymers into water-soluble fragments to generate new small molecular compounds until the water-soluble polymers are finally decomposed into CO₂And H₂O。

Before the biodegradable film is extruded through the extruder, the backing material needs to be stirred and mixed, the structure of the existing stirring device is unreasonable, the stirring force is insufficient, the granularity of the material is large, in addition, dead angles exist in the stirring, the material is not uniformly mixed, and the product quality is reduced.

Agitating unit is used in biodegradable plastic film production, which comprises a tank body, the discharge opening, discharge valve and top cap, the inside upper end of the jar body is fixed with grinds the seat, it divide into grinding chamber and teeter chamber with jar internal portion to grind the seat, the top of grinding the seat is equipped with the grinding groove of infundibulate, it grinds the blanking mouth of chamber and teeter chamber to be equipped with the intercommunication on the seat to grind, the lateral wall upper end of the jar body is equipped with and grinds the feed back mouth of chamber intercommunication, the lateral wall middle part of the jar body is equipped with the charge door with the teeter chamber intercommunication, the bottom of the jar body is equipped with inhales the material mouth, inhale the import that the material mouth connects the circulating pump through inhaling the material pipe, the export of circulating pump is through arranging material union coupling feed back mouth, be fixed with the motor on the top cap, the pivot hookup of motor has the center pin.

The feed inlet is matched with a protective cover to play a protective role.

The top of the grinding body is conical, so that circulating materials can conveniently enter the grinding groove.

And a baffle corresponding to the feed back port is fixed at the bottom of the top cover.

The transverse section of the baffle is arc-shaped, so that the circulating materials uniformly fall into the grinding groove.

Compared with the prior art, the utility model beneficial effect who has is:

agitating unit is used in biodegradable plastic film production, grind the material through grinding seat and rinding body, make the material more meticulous to, go into the grinding groove again with the material of jar body die angle department through the circulating pump and grind, constantly circulate and make the material mix more evenly, effectively improved product quality.
