This utility model discloses an industrial processing fluid filtration system using the coagulation and diversion principle, comprising a three-compartment water tank, a low-voltage AC particle coagulation device, and a diversion filter cartridge. The three-compartment water tank is divided into a sludge tank, a filtration tank, and a supply tank. The low-voltage AC particle coagulation device includes a cylindrical electrode and an electrical control box. The diversion filter cartridge includes a cylindrical filter, and the interior of the cylindrical filter has a filter element parallel to the axis of the cylindrical filter. The three-compartment water tank, the low-voltage AC particle coagulation device, and the diversion filter cartridge are connected sequentially by water pipes. This industrial processing fluid filtration system using the coagulation and diversion principle is advanced in design, compact in structure, and easy to use. It aggregates fine particles in the processing fluid into larger particles, facilitating subsequent filtration, improving filtration efficiency and accuracy, and preventing excessive deposition and compaction of particles on the filter element surface, thus extending the service life of the filter element and avoiding frequent replacement.

The application discloses a coarse particle flotation machine, and particularly relates to the technical field of flotation machines, which comprises a flotation bin, a flotation mechanism, a driving mechanism, a scraping mechanism and a feeding mechanism, and further comprises a protection mechanism and a deposition treatment mechanism. Through the arrangement of the protection mechanism, the first jetting ports arranged in an inclined manner can spray upwardly moving rotating air flow to the inner wall of the flotation bin during the working process of the flotation machine. On the one hand, the coarse particles can be effectively reduced in deposition at the bottom or the corners, and when the coarse particles sink due to gravity, the upwardly moving rotating air flow can push the particles to move along a spiral track, prolong the residence time of the particles in the bubble enrichment area, and increase the collision frequency of the particles and the bubbles. On the other hand, the sprayed gas can form bubbles, the bubbles can collide with the coarse particles in the ore pulp, provide buoyancy for the upward floating of the coarse particles, reduce the deposition of the particles, and thus improve the recovery rate of the coarse particles and the flotation efficiency.

This invention discloses an automated spraying system for the maintenance of bridge and culvert structures, belonging to the field of bridge and culvert maintenance technology. It includes a drive rod with an end seat connected to one end. A supporting outer ring is provided outside the end seat. It also includes a first support mechanism, with multiple first support mechanisms arranged around the outside of the supporting outer ring. A first spraying maintenance mechanism is connected to the side of each first support mechanism away from the supporting outer ring. In this invention, the problem of water dripping from the top is completely solved through adhesive immersion maintenance. The first support mechanism expands radially, driving the first spraying maintenance mechanism to fully adhere to and press firmly against the inner side of the component to be maintained. The maintenance liquid is directly injected into the first adhesive part for contact immersion, effectively avoiding the problem of rapid water dripping from the top in traditional spraying. This greatly improves the moisturizing and maintenance effect on the top and side walls of the component's inner cavity, while also preventing excessive water deposition at the bottom.
