[0016] The utility model discloses a kettle body 1 is connected with the feed pipe 2 on the upper end, is connected with the discharge pipe 3 on the lower end, is equipped with the stirring shaft 4 at the axis of kettle body 1, and the stirring shaft 4 is evenly distributed with multiple groups of wall scraping units on the circumference, and each group of wall scraping units includes two radial rods 5, and the two radial rods 5 are fixed at the two ends of stirring shaft 4 and are vertically aligned, and the outer end between the two radial rods 5 is connected with a rotating shaft 6 parallel to stirring shaft 4, and the rotating shaft 6 is fixed with a scraper 7 parallel to the rotating shaft 6, and the rotating shaft 6 is located at the outer side of the midline of the scraper 7, and the outer side refers to the side close to the inner wall of kettle body 1, that is to say, the area of the inner side of the scraper 7 is greater than the area of the outer side with the rotating shaft 6 as the boundary, and the rotating shaft 6 is equipped with a torsion spring 8, and the torsion spring 8 makes the outer side of the scraper 7 adhere to the inner wall of kettle body 1, when the stirring shaft 4 stirs the material in kettle body 1 clockwise, the material will generate resistance on the surface of the scraper 7, and since the scraper 7 is asymmetric about the rotating shaft 6, therefore the resistance will make the scraper 7 generate a clockwise torque, and the torque makes the scraper 7 rotate clockwise to overcome the action of the torsion spring 8, and the outer side of the scraper 7 is separated from the inner wall of kettle body 1, avoiding increasing the stirring resistance, kettle body 1 is equipped with a water pipe 9 at the top, and the water pipe 9 is equipped with a spray head at the end, and the water outlet of the spray head can cover the inner wall of kettle body 1, when cleaning the inner wall of kettle body 1, the stirring shaft 4 rotates counterclockwise, and the scraper 7 adheres to the inner wall of kettle body 1 under the action of the torsion spring 8, and the inner wall of kettle body 1 is cleaned and scraped.

[0017] The scraper 7 is composed of a base plate 10 and a rubber scraping strip 11, and the rubber scraping strip 11 is fixed on the outer side of the base plate 10 through a screw, and the rubber scraping strip 11 contacts the inner wall of kettle body 1, and the rubber scraping strip 11 is consumable and can be replaced.

[0018] The stirring shaft 4 is fixed with a plurality of stirring rods 12, and the material in kettle body 1 is fully stirred.

[0019] The included angle between the scraper 7 and the inner wall of the kettle body 1 is an acute angle, so that the scraper 7 has the effect of gathering the material on the outer side to the middle side when stirring the material, and the relative movement between the scraper 7 and the inner wall of the kettle body 1 is smoother when washing.

[0020] The water pipes 9 and the nozzles are circumferentially distributed, so as to ensure the complete coverage of the inner wall of the kettle body 1.

[0021] When stirring, the stirring shaft 4 rotates clockwise, the stirring rod 12 and the scraper 7 stir the material in the kettle body 1, the counterforce of the material on the scraper 7 is unbalanced on the inner and outer sides of the rotating shaft 6 when the scraper 7 rotates clockwise, so that the clockwise torque is generated, the torque makes the scraper 7 rotate clockwise around the rotating shaft 6 against the action of the torsional spring 8, the rubber scraping strip 11 of the scraper 7 is separated from the inner wall of the kettle body 1, so as to avoid increasing the stirring resistance and reducing the abrasion of the rubber scraping strip 11, meanwhile, the inclined scraper 7 has the effect of gathering the material to the center, so as to promote the exchange of the material on the inner and outer sides and improve the stirring efficiency; when the stirring approaches the end, the stirring shaft 4 can be stirred counterclockwise for about one minute, the torque of the material resistance on the scraper 7 becomes counterclockwise when stirring counterclockwise, under the superimposed action of the counterclockwise torque and the force of the torsional spring 8, the rubber scraping strip 11 is attached to the inner wall of the kettle body 1, if the material is adhered to the inner wall of the kettle body 1, the material can be scraped off by the rubber scraping strip 11.

[0022] After the material is discharged, the top water pipe 9 is opened, the nozzles spray water to cover the inner wall of the kettle body 1, the stirring shaft 4 rotates counterclockwise, under the action of the torsional spring 8, the rubber scraping strip 11 is attached to the inner wall of the kettle body 1, so as to wash the inner wall of the kettle body 1 until the washing is completed.

[0023] The scraper 7 is installed on the stirring shaft 4, the asymmetric installation of the scraper 7 and the resistance of the material on the scraper 7 during stirring make the scraper 7 separate from the inner wall of the kettle body 1 during stirring and have the effect of gathering the material to the center, the scraper 7 is attached to the inner wall of the kettle body 1 during flushing, so that the washing device and the stirring device are integrated, the stirring is not affected and the stirring efficiency is improved, meanwhile, the inner wall of the kettle body 1 can be conveniently and effectively cleaned.
