Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

1-3, a fermentation device for producing polylactic acid includes a fermentation body 1, to which a feed pipe 2 is fixedly connected, to which two fixed plates 7 are fixedly connected, to which a rotating rod 5 is rotatably mounted, to which two pull ropes 6 are arranged, and a scraper 20 with a U-shaped cross section is slidably mounted in the fermentation body 1, to which a support plate 19 is fixedly mounted, one end of each pull rope 6 is fixedly connected to the support plate 19, to which a water spray assembly is arranged, and the water spray assembly includes a water tank 16 fixedly mounted on the support plate 19, to which a plurality of water spray pipes 17 are connected via a booster pump, and to which a corrugated pipe 4 is fixedly connected.

A first telescopic rod 18 is fixedly connected to the support plate 19, and the first telescopic rod 18 is fixedly connected to the upper inner wall of the fermentation body 1. During the unwinding of the pull rope 6, the scraper 20 moves vertically downward under the action of gravity, and the first telescopic rod 18 is stretched and deformed at the same time. The first telescopic rod 18 can limit the movement trajectory of the scraper 20, making its movement more stable. The cross-section of the rotating rod 5 is T-shaped, and the rotating rod 5 is connected to the fixed plate 7 through the threaded rod 3. The fixed plate 7 is provided with a plurality of grooves for connecting the threaded rod 3. The threaded rod 3 is rotated to be threadedly connected to the rotating rod 5 until one end of the threaded rod 3 is engaged with the corresponding groove, which can prevent the rotating rod 5 from subsequently rotating relative to the fixed plate 7.

A sealing cover 9 is clamped on the fermentation body 1, and the sealing cover 9 is connected to the fermentation body 1 by a bolt 8. The bolt 8 is rotated so that one end of the bolt passes through the sealing cover 9 and is connected to the fermentation body 1, which can prevent the sealing cover 9 from being separated from the fermentation body 1. A rotating shaft 13 is rotatably installed in the fermentation body 1, and a stirring blade 15 is fixedly connected to the rotating shaft 13. A first motor is installed on the fermentation body 1, and the driving end of the first motor is fixedly connected to the rotating shaft 13. Under the driving action of the first motor, the rotating shaft 13 and the stirring blade 15 rotate at the same time, which can turn over the raw materials inside the fermentation body 1, which is conducive to more complete fermentation of the raw materials.

A reciprocating screw 14 is rotatably installed in the fermentation body 1, a fixed sleeve 12 is threadedly connected to the reciprocating screw 14, a push plate 10 is fixedly connected to the fixed sleeve 12, a second telescopic rod 11 is fixedly connected to the fixed sleeve 12, the second telescopic rod 11 is fixedly connected to the inner wall of the fermentation body 1, a second motor is arranged on the fermentation body 1, a driving end of the second motor is fixedly connected to the reciprocating screw 14, under the driving action of the second motor, the reciprocating screw 14 rotates, the fixed sleeve 12 moves along the reciprocating screw 14, and during the movement of the push plate 10, the solid raw material can be pushed out from the discharge port.

In the utility model, when in use, one end of the bellows 4 is connected to an external water source, and a water pump is used to transport the water source through the bellows 4 to the water tank 16, so that the rotating rod 5 and the fixed plate 7 rotate relative to each other, and the pull rope 6 wound on the rotating rod 5 is unwound. Under the action of gravity, the scraper 20 will move downward along the inner wall of the fermentation body 1, and the support plate 19 will move vertically downward at the same time. The water spray pipe 17 on the water tank 16 is arranged below the scraper 20. Under the action of the booster pump (not shown), water flows through each water spray pipe 17 and is sprayed onto the inner wall of the fermentation body 1, so that most of the raw materials adhered to the inner wall of the fermentation body 1 can be washed away. The side of the scraper 20 close to the inner wall is an inclined surface. During the downward movement of the scraper 20, the raw materials tightly adhered to the inner wall can be scraped off, so as to avoid residual raw materials on the inner wall of the fermentation body 1, and the cleaning of the fermentation body 1 is more thorough, which is beneficial to the subsequent use of the fermentation device.

In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
