Mixing pan cleaning device of vertical mixing machine

Abstract

The invention discloses a mixing pan cleaning device of a vertical mixing machine. The mixing pan cleaning device comprises a rotary spindle assembly and spatial connecting rod type shears-fork extensible hairbrush assemblies, wherein the rotary spindle assembly comprises an upper-portion rotary shaft, a connecting flange and a lower-portion connecting support, each spatial connecting rod type shears-fork extensible hairbrush assembly comprises an air cylinder, a first guide frame, an air cylinder ejection block, a moving rod, a side cleaning hairbrush and a shear type expansion plate. The mixing pan cleaning device adopts the design of a spatial connecting rod mechanism, is simple in structure, safe and reliable, can achieve the expansion, can be suitable for cleaning of mixing pans of different volumes, and meanwhile facilitates the separation of the device and the mixing pans after installation and cleaning operations are completed.

Description

Technical field [0001] The invention belongs to the field of vertical mixers, and more specifically, relates to a mixing pot cleaning device of a vertical mixer. Background technique [0002] The mixing pot is the key equipment in the solid propellant preparation process. It is mainly used for material shipment and cooperates with premixers, vertical mixers, and other equipment to complete the premixing and mixing of solid propellant formulations. The mixing pot is made of stainless steel, and the wall and bottom of the pot have structures such as heat-preserving inner tank and water circulation pipeline. [0003] Due to the high viscosity of the solid propellant slurry, after the pouring operation of the mixing pot is completed, there are still more materials adhering to the pot wall. The mixing pot must be cleaned of the adhered materials on the pot wall before entering the next cycle Materials, pre-mixing and mixing operations. Traditional small mixing pots are basically clean...

AI Technical Summary

Problems solved by technology

Traditional small mixing pots are basically cleaned manually by workers, which is inefficient and dangerous

The strong smell of the material will greatly damage the health of the workers

However, the surface area of ​​the wall of the large mixing pot increases significantly, and manual cleaning is very difficult, and once a fire or explosion accident occurs during the cleaning process, it will pose a serious threat to the lives of workers.
