Description

Technical Field

[0001] This utility model relates to the field of vacuum permanent magnet filtration technology, specifically to a permanent magnet vacuum filtration device. Background Technology

[0002] The vacuum permanent magnet filter is a top-feed cylindrical external filter type, mainly suitable for dewatering coarse-grained strongly magnetic materials. The cylinder is equipped with a strontium ferrite permanent magnet system, which promotes the rapid adsorption of magnetic particles onto the filter cloth surface. The filter is primarily used for dewatering coarse-grained strongly magnetic mineral concentrate slurries. Due to the top feeding method, the stratification of the concentrate in the filter cake according to particle size is more pronounced. When the magnetic concentrate forms a filter cake, the particles are simultaneously subjected to gravity and magnetic force, separating coarse particles from fine particles. The finer particles of the ore move towards the filter cloth faster than the coarser particles, resulting in better air permeability of the filter cake. Furthermore, the magnetic particles in the slurry are radially distributed on the surface of the cylinder under magnetic attraction, and the magnetic agitation is generated due to the change in magnetic polarity. These factors contribute to the easy dehydration of the filter cake, resulting in a thicker and more permeable filter cake, which significantly improves productivity. Compared with a cylindrical vacuum filter of the same specifications, its efficiency is more than three times higher, making it an indispensable magnetic filtration device for solid-liquid separation of magnetic ores.

[0003] The existing device has the following shortcomings:

[0004] 1. After a period of use, the filter cloth is prone to getting dirty, that is, mud adheres to the surface of the filter cloth, causing the filter pores to become clogged, which will reduce the filtration effect of the device. The filter cloth needs to be cleaned manually, which is slow and has low cleaning efficiency.

[0005] 2. Although some devices are designed with cleaning brushes that can clean the mud on the surface of the filter cloth, the cleaning brushes cannot completely remove the solidified mud after the mud solidifies and becomes harder, thus reducing the cleaning effect on the filter cloth.

[0017] The beneficial effects of this utility model are:

[0018] This invention, through the design of a controller, roller brush, pushing component, and driving component, allows the controller to activate the pushing component after use, pushing the roller brush to contact the filter cloth surface. Then, the driving component is activated to rotate the roller brush, automatically cleaning the mud adhering to the filter cloth surface. This eliminates the need for manual cleaning, saving time and effort and improving cleaning efficiency. The invention also incorporates a controller, supply component, and several atomizing nozzles. While the roller brush cleans the filter cloth surface, the atomizing nozzles spray cleaning fluid onto the surface, wetting the solidified mud and reducing its hardness, thus facilitating easy removal of the mud by the roller brush and improving cleaning effectiveness. Finally, the permanent magnet vacuum filtration device of this invention, by activating the filter cylinder to rotate, simultaneously sprays cleaning fluid onto the filter cloth and cleans it with the roller brush. The rotation of the filter cylinder ensures that all filter cloth on the outer wall of the cylinder is cleaned, achieving a thorough cleaning effect and improving the filtration efficiency of the device, preventing any cleaning omissions.
