Mixer and dewatering method thereof
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mixers face difficulties in dewatering due to blocking components, such as seeds or viscous lumps, which are larger than the dewatering hole, preventing efficient juice extraction.
Innovation Solution
A mixer design featuring a scraper on the inner container's outer side surface and a dewatering container speed change device to create a rotational speed difference, allowing the scraper to remove blocking components from the dewatering hole, combined with a dewatering unit that surrounds the inner container to facilitate efficient juice extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a pulverizing blade is used to crush the mixing object, then the mixing object is pulverized, but blocking components larger than the dewatering hole are formed, preventing dewatering
Solution Approach 1:
The scraper is designed to extract and remove blocking components from the dewatering hole area. The scraper protrudes from the inner container's outer side surface and actively scrapes off blocking components that would otherwise obstruct the dewatering hole, separating the blocking component removal function from the pulverization function.
Solution Approach 2:
The scraper acts as an intermediary element between the inner container and the blocking components. It mediates the interaction by providing a mechanical scraping action that removes blocking components without requiring direct contact between the pulverizing blade and the dewatering hole area.
2Productivity
If the dewatering hole size is increased to allow blocking components to pass, then dewatering efficiency improves, but the structural integrity and filtering capability are compromised
Solution Approach 1:
Instead of enlarging the dewatering hole, the solution extracts and removes blocking components before they can obstruct the hole. The scraper actively takes out blocking components from the vicinity of the dewatering hole, allowing the hole to maintain its original size and filtering capability while ensuring continuous dewatering operation.
3Productivity
If a scraper is added to remove blocking components, then dewatering continuity is improved, but the device complexity increases
Solution Approach 1:
The scraper is merged with the inner container structure, protruding from its outer side surface. This integration combines the scraping function with the existing container structure, avoiding the need for a completely separate scraping mechanism and thereby reducing overall device complexity while maintaining dewatering continuity.
Solution Approach 2:
The scraper is positioned to automatically scrape blocking components as the inner container rotates during the mixing and dewatering process. The rotational motion of the container itself provides the scraping action, eliminating the need for additional motors or actuators, and allowing the system to serve itself without external intervention.
4Device complexity
If the inner container and dewatering container rotate at the same speed, then the structure is simple, but the scraper cannot effectively remove blocking components
Solution Approach 1:
The system transitions from a static same-speed rotation to a dynamic differential speed rotation. The inner container and dewatering container rotate at different speeds, creating relative motion between the scraper and blocking components. This dynamic speed difference enables the scraper to effectively contact and remove blocking components while maintaining a relatively simple rotation control structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively increases the efficiency of dewatering by ensuring that blocking components are removed, allowing for continuous and effective juice extraction from the mixing object.
Implementation Method 1
a scraper which protrudes from an outer side surface of the inner container to scrape off a blocking component of the mixing object blocking the dewatering hole of the dewatering container when there is a difference in the rotational speeds between the inner container and the dewatering container
