Description

Technical Field

[0001] The utility model belongs to the technical field related to raw material mixing devices, and specifically relates to a raw material mixing device for producing autotrophic denitrification fillers. Background Art

[0002] Denitrification filler is an environmentally friendly material specially used for denitrification and dephosphorization in sewage treatment processes. It is generally made of polymer materials such as plastics or synthetic resins. There are two types of internal structures, one is a honeycomb structure and the other is a ring structure. The characteristics of the two structures are different. The honeycomb structure is mainly used to remove organic matter and ammonia nitrogen in water, while the ring structure is mainly used to remove total nitrogen in water. During the production of fillers, the raw materials need to be mixed. When the existing mixing device adds the raw materials into the mixing device through the feeding port, the raw materials fall directly to the bottom of the mixing device. Different raw materials are stacked at different heights and are relatively concentrated. The mixing process needs to be fully mixed, resulting in a long mixing and stirring process.

[0003] In view of this, the present utility model is proposed. Utility Model Content

[0026] Among them, there are multiple feeding pipes 4, and the length of the lower end of the feeding pipe 4 extending downward is matched with the material guide rail 5. The material guide rail 5 is a spiral structure to ensure that the raw materials falling from the feeding pipe 4 can completely fall on the material guide rail 5.

[0027] The feeding and dispersing device 8 is designed as a three-layer structure, with the upper layer being the upper dispersing sheet 16, the middle being the middle dispersing sheet 17, and the lower layer being the lower dispersing sheet 18. The upper dispersing sheet 16, the middle dispersing sheet 17, and the lower dispersing sheet 18 are all designed as umbrella-shaped structures with spaced grooves. The spaced grooves between adjacent layers are staggered with each other. The feeding and dispersing device 8 can fully disperse the raw materials and avoid concentrated stacking of single raw materials.

[0028] There are multiple groups of stirring devices 9 in the upper and lower directions, and the stirring rods of each group of stirring devices 9 are set with different length specifications to ensure the uniformity of the mixing and stirring process.

[0029] The mixing scraper device 10 includes a short scraper device 19 and a long scraper device 20 . Three short scraper devices 19 and three long scraper devices 20 are evenly distributed along the circumferential direction to fully scrape and separate the materials on the spacer bottom plate 11 .

The feeding and dispersing device 8 is designed in an umbrella-shaped structure with three layers of spaced grooves. It can rotate under the power of the power motor 15 and the rotating shaft 7 to fully disperse the raw materials and avoid the concentrated stacking of single raw materials. The raw materials can be mixed during the process of being dispersed and fallen, and can be fully mixed with the stirring device 9 and the mixing scraper device 10, which can effectively improve the raw material mixing efficiency.
