Integrated equipment for processing nano calcium carbonate of polyurethane adhesive

Abstract

The integrated equipment comprises a base, a drying device and a grinding device are arranged above the base, a stand column is rotationally connected to the side, close to the grinding device, of the top of the base, and a rotating disc is fixedly connected to the top of the stand column; two symmetrically-distributed material collecting barrels are arranged at the bottom of the rotary disc, a protrusion is fixedly connected to one side of the bottom of each material collecting barrel, a material blocking cover matched with the material collecting barrels is arranged at the ends, away from the rotary disc, of the material collecting barrels, and the material blocking covers are rotationally connected with the protrusions. According to the nano calcium carbonate raw material drying device, through mutual cooperation of the arranged shaft rod, a second motor, a stirring piece and a filter screen, the drying efficiency can be effectively improved, the problem that a nano calcium carbonate raw material is agglomerated in the drying process is solved through the arranged stirring piece, and the arranged filter screen can effectively prevent the agglomerated nano calcium carbonate raw material from entering and exiting the material collecting barrel; and the discharging quality of the dried raw materials is ensured.

Description

technical field [0001] The invention relates to the technical field of nanometer calcium carbonate processing equipment, in particular to an integrated equipment for nanometer calcium carbonate processing of polyurethane glue. Background technique [0002] In recent years, with the emergence of nanotechnology, calcium carbonate has entered the nano era, and has driven the development of papermaking, plastics, rubber, high-grade coatings and other fields. However, the output of calcium carbonate and active calcium continues to grow. Nano calcium carbonate is widely used in rubber, plastics, paper, chemical building materials, inks, coatings, sealants and adhesives. The production process of nano calcium carbonate Generally, the steps of drying of raw materials, grinding and collection of finished products are performed. After the dehydrated calcium carbonate is dried, it needs to be transferred to the pulverizer. Manual collaboration is required, which is laborious and labor...

Problems solved by technology

[0002] In recent years, with the emergence of nanotechnology, calcium carbonate has entered the nanometer era, and has driven the development of papermaking, plastics, rubber, high-grade coatings and other fields. At present, light calcium carbonate has been basically eliminated in western developed countries, while nanoscale The production of calcium carbonate and active calcium continues to grow. Nano-calcium carbonate is widely used in industries such as rubber, plastics, papermaking, chemical building materials, inks, coatings, sealants and adhesives. The production process of nano-calcium carbonate Generally, there are steps such as raw material drying, grinding and finished product collection. After the dehydrated calcium carbonate is dried, it needs to be transferred to the pulverizer. However, the current transportation device for calcium carbonate to the pulverizer is very inconvenient and often Manual collaboration is required, laborious and labor-intensive, and work efficiency is reduced. For this purpose, an integrated equipment for nano-calcium carbonate processing of polyurethane glue is provided.
