Mixing Machine Self-Cleaning System for Viscous Granule Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mixing machines for producing viscous mixtures from granules and binding agents often suffer from blockages, inadequate mixing, and rapid wear, particularly when handling coarse to very fine granules, leading to leftover mixture residue and maintenance challenges.
Innovation Solution
A mixing machine with a self-cleaning system, featuring a cleaning plate driven by a cylinder and specific rotors with push and mixing blades, ensures thorough mixing and complete removal of the mixture from the chamber, preventing residue and wear by using a divided mixing chamber with push, mixing, and discharge zones, and adjustable rotor speeds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mixing machines are used to mix granules with binding agents, then mixing function is provided, but mixture residue remains in the chamber causing blockages and wear
Solution Approach 1:
The mixing machine performs self-cleaning through an integrated cleaning plate that automatically removes mixture residue from the mixing chamber and rotor blades after each mixing cycle, eliminating the need for manual intervention and preventing blockages that would otherwise occur
Solution Approach 2:
The cleaning plate is positioned to contact and scrape the mixing chamber walls and rotor blades during or immediately after the mixing cycle, preventing residue from hardening and causing blockages before they can form
2Duration of action of stationary object
If mixing machines operate without self-cleaning systems, then device complexity is reduced, but rapid wear of mixer parts occurs due to residue accumulation
Solution Approach 1:
The mixing machine automatically cleans its own components through a mechanically actuated cleaning plate that scrapes residue from the mixing chamber and rotor blades, extending component life without requiring external cleaning systems or manual maintenance
Solution Approach 2:
The cleaning function is separated as a distinct mechanical component (cleaning plate) that can be independently actuated, allowing the cleaning mechanism to be simplified while still effectively removing residue from critical mixing surfaces
3Object-generated harmful factors
If flushing with granules is used to remove residue, then cleaning is achieved, but wear and tear to mixer parts increases
Solution Approach 1:
The machine uses its own mixing components (cleaning plate and rotor blades) to mechanically remove residue through scraping and shearing actions, eliminating the need for abrasive granule flushing that causes wear to the mixing chamber and blades
