This utility model relates to the field of dust and waste conveying technology, and in particular to a closed conveying device for dust and waste from roadheaders and anchorers. It includes a conveying frame, a conveying component, and multiple idlers. The conveying frame has two first conveying rollers symmetrically and rotatably connected to its inner wall. The conveying component includes a conveyor belt tensioned and sleeved on the two first conveying rollers. The working surface of the conveyor belt has a V-shaped conveying groove along its width. Multiple idlers are arranged at intervals along the conveying direction within the conveying frame and are rotatably connected to the inner wall of the conveying frame. In this utility model, the V-shaped conveying groove on the working surface of the conveyor belt effectively constrains the waste, preventing it from dispersing during conveying, reducing the exposed area of ​​the waste, and lowering the possibility of dust generation. The idlers provide linear support to the conveyor belt, ensuring stable operation and preventing waste from scattering due to belt swaying, thus improving the stability and reliability of the conveying process.

The present invention relates to the technical field of multi-stage sewage treatment, and discloses a sewage treatment device and a sewage treatment system for esterification reaction, including a main body, wherein a regulating tank, a flocculation tank and a sedimentation tank are arranged inside the main body, and a partition is fixedly connected inside the regulating tank, and the partition divides the regulating tank into a plurality of chambers. The present invention is conducive to realizing a decentralized step-by-step neutralization operation by dividing the regulating tank into a plurality of chambers in series, and providing a barrel and an agitator matching the chambers. Compared with the method of centralized agent neutralization, the probability of the occurrence of agent agglomerates is smaller, and by providing a screen drum, an inclined blade, a drive assembly and a transmission assembly, it is possible to collect agglomerates that are difficult to disperse, and then grind them above the sewage liquid surface and then re-put them into the sewage for dispersion, further solving the problem that a small amount of agglomerates are difficult to disperse, thereby improving the neutralization effect, reducing the amount of sludge in the sewage, and reducing the sludge treatment pressure of the subsequent sedimentation tank.

The application discloses a carbon nanotube and carbon black composite conductive filler and a PVC conductive composite material and a preparation method thereof. The carbon nanotube and carbon black composite conductive filler comprises a composite of carbon nanotubes and carbon black obtained by mixing carbon nanotubes after surface grafting and carbon black after surface grafting through ball milling and grinding, and forms a conductive filler with a "grape cluster" structure. The structure utilizes the long-axis structure of the carbon nanotubes, prolongs the axial length of the carbon black, forms a rich conductive network, changes the point-like conduction of the carbon black into linear conduction, and after coupling, the conductive performance can be greatly improved.
