Description

Technical Field

[0001] This utility model belongs to the field of pulp recycling, specifically relating to a pulp recycling mechanism for a pulping machine. Background Technology

[0002] In the textile industry, sizing machines significantly improve production efficiency by integrating warping and sizing processes. However, the large amount of waste sizing material generated during the sizing process increases production costs and causes environmental pollution. Untreated sizing wastewater often has a chemical oxygen demand (COD) several times higher than national emission standards, seriously impacting the ecological environment.

[0003] Currently, tubular filters are widely used in slurry recovery from pulping and finishing machines due to their advantages such as large pipe diameter and strong anti-fouling ability. They purify the slurry by trapping impurities such as fiber debris and suspended solids in the slurry through filter media inside or outside the pipe. To address the problem of filter cartridge clogging during filtration, a backwashing structure is usually installed at the bottom of the tubular filter. This uses a reverse high-pressure water flow to clean the filter cartridge online, ensuring stable filtration flux. However, while this design effectively extends the service life of the filter cartridge, the backwash water flow carries away a large amount of unfiltered slurry during backwashing, resulting in significant resource waste.

[0004] Therefore, there is an urgent need to develop a slurry recovery mechanism for a slurry processing unit that can reduce slurry waste during backwashing. Utility Model Content

[0016] (3) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention features a flushing mechanism. Starting the motor causes the rotating rod to rotate, which in turn rotates the cylinder and the connecting pipe. The connecting pipe moves to the lower end of the inlet below the filter element. Then, the sealing pipe above the filter element is rotated, causing it to become loose. The sealing pipe then slides down to the outer end of the filter element. This prevents the slurry inside the filter tank, located above the baffle, from flowing through the filter element into the connecting pipe. Waste material in the connecting pipe automatically slides down into the connecting pipe and is then discharged through the cylinder from the drain pipe, thus reducing slurry waste.

[0019] This utility model incorporates a disassembly and assembly unit. When a filter element is damaged and needs replacement, the nut on top of the filter element is rotated to remove it from the outside of the threaded rod, thus freeing the pressure plate from being fixed above the vertical rod. Then, the handle is moved upwards to remove the pressure plate from above the filter element, allowing the filter element to be removed from the vertical rod for replacement.
