The raw material mixing device is simple in structure and convenient to operate, the raw material mixing effect is improved, meanwhile, workers can conveniently replace and disassemble any group of damaged scrapers independently, then the practicability of the device is improved, and the problems that the raw materials are prone to being adhered to the inner wall of the tank body, the mixing amount is reduced, the batch shipment amount is reduced, and the finished product quality is affected due to uneven mixing are solved.

An intelligent mine monitoring system disclosed by the present invention comprises a mounting base, a monitoring device is arranged on the mounting base, a camera is arranged on the monitoring device, and the monitoring device comprises a transmission module, an intelligent control module and an image acquisition module connected with the camera. The image collection module transmits images collected by the camera to the intelligent control module through the transmission module, the collected images are recognized and judged through the intelligent control module, and the judgment result is divided into two types of being lower than a cleaning threshold value and being higher than the cleaning threshold value. The dirt degree of a camera lens can be automatically judged according to an image collection result, cleaning is accurately started and finished, excessive or insufficient cleaning is avoided, a water spraying wiping + air spraying cleaning + air drying combined mode is adopted, water beads and air drying equipment are blown through the elastic cleaning part in cooperation with warm water wiping and washing, cleaning is more thorough, and the cleaning efficiency is improved. And efficient cleaning and air drying are achieved.

The utility model relates to microplastic enrichment technical field discloses a kind of microplastic enrichment devices, including enrichment box, first passage is arranged in enrichment box inside one side, second passage is arranged in enrichment box inside other side, and electric valve is fixedly installed in first passage and second passage inside one side. The utility model technical scheme is passed through the liquid inside containing microplastic being filtered by filter cartridge distributed by first passage when liquid is constantly circulated from first passage inside, when a large amount of microplastic is filtered out in filter cartridge inner wall, filter cartridge inner wall will have a large amount of microplastic adhering, liquid in first passage will constantly extrude filter cartridge, promote filter cartridge constantly move to liquid flow direction, since pull rope is connected between two groups of filter cartridges, when being located in one group of filter cartridge moves downward, another group of filter cartridges will move reversely upward, and butt joint with cleaning assembly, the microplastic adhering in filter cartridge inner wall is cleaned, avoid filter cartridge inner wall adhering a large amount of microplastic, affect enrichment box inside liquid flow.

The utility model relates to the field of cleaning tools, and discloses an adjustable top ultraviolet lamp tube wiper which comprises a fixing rod, a control handle is arranged on the surface of the fixing rod, a threaded rod is connected to the inner wall of the fixing rod in a threaded mode, an alcohol cylinder is fixedly connected to the outer wall of the threaded rod, and a fixing base is fixedly connected to the top end of the threaded rod. The inner wall of the fixing seat is fixedly connected with a fixing ring, the inner wall of the fixing seat is rotatably connected with an opening and closing ring, the inner surface of the opening and closing ring is fixedly connected with an atomizing nozzle, and the inner wall of the opening and closing ring is in threaded connection with an adjusting bolt.
