2. Clean scraper device is mainly aimed at materials that are not particularly viscous, and may be adsorbed on the pipe wall for a long time, which will lead to blockage. For this reason, we also specially study a kind of clean scraper to solve this problem. This kind of clean scraper is to install a piece of soft material on the ordinary scraper (the specific scraper material according to the characteristics of the material) which is straighter than the ordinary scraper. The diameter is slightly larger, so that the material adsorbed on the pipe wall can be removed during operation, thus ensuring the cleaning of the pipe wall.
3. Brush cleaning device, this device does not necessarily need to be placed in the outlet, the connection can also be through adding brushes at the connection, motor driven brush operation, pipe wall and chain operation to the brush position, can achieve the effect of automatic cleaning.
