2results about How to "Scrape evenly" patented technology

This invention discloses a rubber component hot-melt crushing and recycling device. The crushing chamber includes two linked crushing shafts. The crushing shafts have internal cavities, and nozzles communicating with these cavities are located on their outer walls. The hot-melt chamber includes a first contraction section and a discharge section. A sleeve is rotatably mounted on the radial outer wall of the discharge section. Multiple slots are formed on the radial outer wall of the discharge section, and multiple discharge ports are formed on its axial outer wall. When the sleeve rotates relative to the discharge section, a scraper cuts the molten rubber at the discharge ports. The sleeve scrapes the radial inner wall of the discharge section to prevent the molten rubber from adhering and accumulating. This invention solves the problem of rubber debris adhering to the crushing rollers through the air-blowing structure of the internal cavity of the crushing shaft and the nozzles, improving crushing efficiency and continuity. The combination of the discharge section with the rotating sleeve and scraper structure allows for uniform cutting of the molten rubber and real-time scraping of materials adhering to the inner wall, improving discharge smoothness and efficiency.

The application relates to the technical field of chemical equipment, in particular to a wiped film evaporator for chemical reaction, which comprises a heating cylinder, the upper end of the heating cylinder is fixedly connected with a connecting pipe, a fixed column is fixedly arranged in the middle of the inside of the heating cylinder, a rotating pipe is rotatably connected to the outside of the fixed column, the rotating pipe is rotatably connected to the inside of the heating cylinder, a plurality of fixed pipes are fixedly arranged on the rotating pipe, a fixed scraper is fixedly connected to one end of the fixed pipe, the fixed pipe and the fixed scraper are located in the inside of the heating cylinder, a first soft scraper is fixedly arranged at one end of the fixed scraper, the first soft scraper is tightly attached to the inner wall of the heating cylinder, and the first soft scraper is slidably connected with the inner wall of the heating cylinder. The device can impact the inside of the fixed scraper through the impact ball, so that the fixed scraper and the soft scraper can vibrate, and the material adhered to the soft scraper can be shaken off.
