The application discloses a kind of for tantalum niobium tailings in tin metal recovery's synergistic treatment system, specifically related to metallurgical solid waste resource utilization technical field, acoustic-electricity perception pre-agglomeration module exports pre-agglomeration probability index according to pre-agglomeration threshold value;Heat resistance chromatography module exports the temperature field and fluidized void fraction distribution of suspected agglomeration area;Inhibiting ingredient self-adapting module calculates inhibitor addition rate according to distribution;Wind material decoupling adjustment module exports decoupled wind speed and feed rate set value according to addition rate and bed pressure drop;Chain negative feedback blocking module detects pressure drop deviation to generate feedback correction, superimposed to wind speed set value and reversely adjust feed rate set value, while used to update pre-agglomeration threshold value;The application realizes the online identification of agglomeration precursor, accurate danger area precision inhibiting and the closed-loop cooperation of wind material decoupling, inhibits the nonlinear deterioration of coking loss flow, makes tin recovery rate keep stable when tailings fluctuation, and reduces inhibitor consumption and manual intervention.

The utility model relates to patch resistance substrate production technical field, concretely is a kind of patch resistance substrate cutting dust removal device, including modular quick-release filter element assembly, modular quick-release filter element assembly includes: filter box body;Drawer type filter element module, and the sliding connection is achieved with installation cavity by slide rail structure;Panel locking assembly, preliminary fixing drawer type filter element module is adsorbed magnetism metal block by electromagnet;Pneumatic locking assembly, control unit controls high-pressure gas source to pneumatic seal ring inflation to make it swell and realize sealing and lock;Drawer type filter element module is slidably installed in installation cavity by slide rail assembly, after preliminary positioning is realized by cooperation electromagnet, positioning hole, positioning piece, control unit controls pneumatic seal ring inflation to swell and completely adhere installation cavity wall, complete final locking, pneumatic seal ring cooperation first sealing gasket, second sealing gasket realizes double locking, and the sealing property is superior to traditional mechanical structure, avoid dust leakage, improve the efficiency of filter element replacement on the other hand.

This invention relates to the field of heat exchange technology and discloses a spiral plate heat exchanger with a segmented cylinder. The heat exchanger includes a heat exchanger body, two sets of spiral plates spirally wound around each other inside the heat exchanger body, and a segmented cylinder coaxially embedded within the cavity enclosed by the two sets of spiral plates. A segmented rubber plate is fixedly installed inside the segmented cylinder. This spiral plate heat exchanger with a segmented cylinder, through the spiral wound spiral plates forming interlaced and spaced hot and cold material channels, significantly extends the fluid flow path and increases the effective contact area between hot and cold fluids, resulting in more thorough and uniform heat exchange. Simultaneously, through the synergistic effect between the adjustment mechanism and the segmented rubber plate, the curved, wavy structure formed by the segmented rubber plate actively changes the fluid flow path and state, forcing the fluid to form continuous disturbance and backflow within the channels, fundamentally improving the problems of low heat exchange efficiency and uneven heat exchange in traditional channels.
