Engineering Contradiction Analysis
1Object-affected harmful factors
If conveyor belts are used to transport atomized slip, then product damage is avoided and operational simplicity is maintained, but dust pollution in the working environment increases and fine particles disperse
Solution Approach 1:
The patent applies pneumatic transport by conveying atomized slip through pipelines using controlled air flow instead of mechanical conveyor belts. This encloses the transport process, preventing dust dispersion into the working environment while maintaining efficient material movement through the ceramic production facility.
Solution Approach 2:
The patent creates a controlled atmospheric environment within the pneumatic transport system by regulating air humidity, temperature, and flow characteristics. This controlled environment prevents uncontrolled dust dispersion and allows for efficient particle transport while protecting the working environment from contamination.
2Object-affected harmful factors
If pneumatic transport is used to eliminate dust pollution, then dust dispersion is reduced, but product integrity may be compromised due to velocity and humidity control challenges
Solution Approach 1:
The patent systematically controls critical parameters including air flow velocity, air humidity, and temperature within the pneumatic transport system. By optimizing these parameters, the system achieves effective dust containment while maintaining product integrity through controlled transport conditions that prevent excessive particle wear and moisture loss.
Solution Approach 2:
The patent implements monitoring and control mechanisms to maintain optimal velocity and humidity levels during pneumatic transport. This feedback control ensures that transport parameters remain within ranges that protect product integrity while effectively containing dust particles within the enclosed system.
3Productivity
If conveyor belt velocity is increased to improve mass flow rate, then transport efficiency increases, but dustiness and particle dispersion increase
Solution Approach 1:
The patent uses pneumatic conveyance where atomized slip is transported through enclosed pipelines using controlled air flow. This allows for high mass flow rates to be achieved while the enclosed nature of the system prevents dust dispersion into the working environment, eliminating the dustiness problem associated with high-velocity conveyor belts.

AI summary
The problems that arise during pneumatic transport of atomized slip are on the one hand that of preventing the air stream from tending to humidify or to dry the atomized product, and on the other hand that of limiting the velocity and the velocity gradient of the solid, relative to the pipe axis, to guarantee its integrity. The solution to the problem of maintaining the humidity of the solid consists of thermal preconditioning of the atomized slip, such as to attain the inlet air condition and maintain constant steam content. At the same time, it is possible, by means of temperature control, to maintain the condition of saturated air as far as the outlet. Therefore, controlling the temperature ensures that the change in steam content in the air between inlet and outlet of the pneumatic conveyor is zero and that the air always remains saturated.
