The raw materials to be stirred are added into the stirring kettle through the feeding pipe, the stirring motor is started, the stirring shaft is driven to rotate by the stirring motor, the spiral scraper blade fixed on the stirring shaft rotates along with the stirring shaft, when the spiral scraper blade rotates along with the stirring shaft, due to the spiral blade surface structure of the spiral scraper blade, the spiral scraper blade pushes the materials to move vertical to the spiral blade surface when rotating, namely, the materials at the position of the spiral scraper blade are pushed to move downwards, and when the spiral scraper blade rotates, the inner wall of the stirring kettle can be effectively scraped, and the materials are pushed to move downwards and are mixed with the materials at the middle position of the stirring kettle after passing through the bottom of the spiral scraper blade, and when the uppermost spiral scraper blade pushes the materials to move downwards, namely, the position forms a pit, due to the fluidity of the materials, the materials at the middle position of the stirring kettle automatically flow to the position of the, and because fixed pipe effect, when the auger delivery leaf rotated, can effectively pass through the auger delivery leaf with the bottom material and rotate upward the removal, the material is discharged through fixed pipe top opening back, can effectively be with stirred tank bottom material and top material intermix to stir in the stirred tank along with the (mixing) shaft rotation through the stirring roller, further stir the material completely, and scrape stirred tank inner wall bottom through the bottom scraper blade, can effectively avoid the unable fully stirred problem of stirred tank bottom to take place.

Preferably, the spiral scraper is opposite to the spiral direction of the spiral conveying blade. Through the effect of spiral scraper blade and auger delivery leaf, can realize that the material flow direction that stirred tank lateral wall and stirred tank inside central point put is opposite to further guarantee the inside material intensive mixing of stirred tank.

Compared with the prior art, the utility model has the advantages that:

1. when rotating through the spiral scraper blade, can effectively scrape the stirred tank inner wall to promote the material downstream, mix with the material of stirred tank intermediate position behind the spiral scraper blade bottom, thereby stir the inside material of stirred tank fully.

2. When the screw conveying leaf rotated, can effectively pass through the screw conveying leaf with the bottom material and rotate upward the removal, the material was discharged through fixed pipe top opening back, can effectively be with stirred tank bottom material and top material intermix, further guaranteed the inside material intensive mixing of stirred tank.

3. The stirring roller rotates along with the stirring shaft to stir the stirring kettle, and further completely stir the materials.

4. Scrape the stirred tank inner wall bottom through the scraper blade, can effectively avoid stirred tank bottom unable intensive mixing's problem to take place.
