And the lug seat is arranged at one end, far away from the bottom plate, of the rib plate, protrudes out of the rib plate, forms a through hole in the center, and is used for being connected with a driving mechanism for driving the push plate to swing along the bearing. The push plate is integrally formed through casting, the problem that the welding position is prone to cracking due to welding and assembling of a plurality of sub-parts is solved, the overall structure is more stable, and the push plate can bear high-frequency and strong-impact contact of ore and large impact force generated when heavy materials are pushed away.

This invention discloses the application of an electrode material for reducing intracellular resistance genes in drug-resistant bacteria. A platinum-doped dendritic TiO2 nanowire structure based on a three-dimensional material is formed by growing a micron-sized TiO2 backbone array and platinum-doped nano-sized TiO2 branches on the surface of a porous electrode. The prepared dendritic nanowire three-dimensional electrode material has a larger specific surface area, providing more reactive sites and strong electric field sites. Platinum doping enhances the conductivity and electrocatalytic performance of the nanowires. Furthermore, by combining it with chloride salts / oxidants, the electroporation and electrocatalysis of the nanowire electrode surface are coupled. The strong electric field confined at the nanowire tip induces perforation of the drug-resistant bacterial cell structure, strengthening the contact and reaction between the oxidant and the resistance gene. The high electrocatalytic activity confined at the nanowire tip induces the generation of strong oxidizing free radicals, achieving the goal of destroying the drug-resistant bacterial cell structure and efficiently reducing intracellular resistance genes.

This invention discloses a low-temperature polyether demulsifier for oil and gas gathering and transportation and its preparation method, relating to the field of petrochemical technology. The key technical points include: using cashew nut shell powder, pentaethylene hexamine, and bisphenol F in a specific molar ratio as an initiator, and preparing a composite initiator via formaldehyde condensation; incorporating propylene oxide and ethylene oxide through staged block copolymerization to form a polyether backbone; introducing fluorinated epoxy monomers for end-fluorination modification; and finally, performing chain extension and crosslinking with adipic acid and epichlorohydrin to obtain a demulsifier with a molecular weight of 8000~12000 Da, a fluorine content of 5.5~6.5 wt%, and a PDI ≤ 1.3. The effect is that through the synergistic effect of the composite initiator, the superhydrophobic penetration of the fluorinated block, and precise molecular weight control, efficient demulsification at low temperatures is achieved, improving demulsification efficiency and reducing dosage, solving the problems of low-temperature failure and easy emulsification of traditional demulsifiers, and adapting to the low-temperature operating conditions of oil and gas gathering and transportation.

The application discloses a deep-cone thickener for concentrating mine tailings slurry and relates to the technical field of mine equipment. The top surface of the conical barrel is fixedly connected with a bridge, the top surface of the bridge is fixedly connected with a speed reducer, the output end of the speed reducer is transmissionally connected with a transmission shaft which is coincident with the axis of the conical barrel, the side surface of the transmission shaft is fixedly connected with multiple groups of cross frames, one end of the cross frame close to the inner wall of the conical barrel is fixedly connected with a mounting seat, and the adjacent two mounting seats which are vertically arranged are rotationally installed with a roller between them. In the application, when the transmission shaft drives the rake frame to slowly rotate, the roller which is tangent to the inner wall of the conical barrel makes the rotation of the rake frame more stable, and the concentricity of the rake frame and the transmission shaft is ensured; in addition, the rotation of the roller makes the rotating disc which is rotationally installed in the inner part of the guide plate reciprocatingly rotate through the cam, so that the contact surface between the floc attached to the guide plate and the rotating disc is damaged, and the floc is separated from the two guide plates.
