The water pump 31 is equipped with a water pumping pipe at its pumping end. The stirring guide component 4 includes a stirring frame 42 that is rotatably connected to the middle of the sand filling shell 1. The edge of the stirring frame 42 is fitted with a part that fits against the inner wall of the sand filling shell 1. The scraper 43 and the top of the sand filling shell 1 are equipped with a motor 41 for driving the mixing frame 42 to rotate. The mixing frame 42 is coaxially fixedly connected to the lower side of the baffle 52. The blade end of the auger 44 is in contact with the inner wall of the casing 51. The water pump 31, three-way valve 32, air supply pipe 33, pressurizing pump 34, branch pipe 35 and spray plate 36 cooperate with each other to achieve pressurization treatment on the upper side of the sand filling shell 1, and to spray cleaning treatment on the mixing frame 42, scraper 43 and inner wall of the sand filling shell 1.

[0028] The main difference between the second implementation method and the first implementation method is that:

The output end of the motor 41 is coaxially and fixedly connected to the stirring frame 42. The corrugated pipe 54 is connected to the inside of the housing 51. The side of the housing 51 is provided with a sliding groove that is slidably connected to the baffle 52. The positions of the two sets of baffles 52 are adjusted by the cylinder assembly 53 to make the housing 51 connected to the inside of the sand filling shell 1. The material that loses its support falls into the housing 51. The rotating auger 44 injects the sand filling material into the middle layer of the double-layer insulated storage tank through the housing 51, the corrugated pipe 54, and the sand filling nozzle 55.

[0030] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0031] In use, the user opens the feed valve 2 to feed the material to be processed into the sand filling shell 1. After feeding is complete, the feed valve 2 is closed. At this time, the sand filling material is located on the upper side of the baffle 52. The motor 41 is started, and the motor 41 drives the stirring frame 42, scraper 43, and auger 44 to rotate. The rotating stirring frame 42 stirs the material in the sand filling shell 1, while the scraper 43 scrapes the inner wall of the sand filling shell 1. The sand filling nozzle 55 is installed on the upper side of the double-layer insulated storage tank at the feed end. After the stirring operation is completed, the positions of the two sets of baffles 52 are adjusted by the cylinder assembly 53 to connect the machine casing 51 with the inside of the sand filling shell 1. The unsupported material falls into the machine casing 51, and the rotating auger 44 carries the sand filling material through the machine casing 51. The corrugated pipe 54 and sand filling nozzle 55 inject sand into the middle layer of the double-layer insulated storage tank. When the sand content stored in the sand filling shell 1 is insufficient, the pressurizing pump 34 is turned on. The pressurizing pump 34, together with the air supply pipe 33, three-way valve 32, branch pipe 35, and spray plate 36, pressurizes the upper side of the sand filling shell 1, promoting the discharge of the retained sand material through the casing 51, corrugated pipe 54, and sand filling nozzle 55. After the sand filling inside the sand filling shell 1 is completely discharged, the sand filling nozzle 55 is separated from the double-layer insulated storage tank, the three-way valve 32 is reversed, and the water pump 31 is turned on. The water pump 31 draws external water and sprays the water through the three-way valve 32, branch pipe 35, and spray plate 36 to clean the mixing frame 42, scraper 43, and the inside of the sand filling shell 1, promoting the removal of residual material from the above components.
