AI Technical Summary
The existing slag removal and discharge devices used in papermaking pulping workshops lack a dynamic adjustment mechanism for the filter cartridges. This results in the inability to form a stable and dense filter cake layer on the inner wall of the centrifugal filter cartridges under low material conditions. The slag is easily detached and flows back into the pulp due to centrifugal force fluctuations, affecting the slag discharge effect.
Design a slag removal and discharge device including a lower centrifugal square cylinder, an upper centrifugal square cylinder, a cylinder, a fixed plate, and a connecting shaft. The cylinder drives the fixed plate and the connecting shaft to raise and lower the upper centrifugal square cylinder, realizing dynamic adjustment of the filter cylinder size and ensuring the stability and accuracy of the distance between the upper and lower centrifugal square cylinders. It is combined with a simple drive method using a single motor and cylinder.
It achieves precise, reliable, and energy-efficient dynamic control of filter cartridge size, avoids slag falling back, significantly reduces equipment energy consumption and operating costs, and improves slag discharge efficiency.
