Description

Self-cleaning feeder Technical Field The utility model relates to the technical field of feeders, in particular to a self-cleaning feeder. Background In the production process of the feed industry, feed mills are often equipped with metal roller feeders, gate feeders or auger feeders. The roller feeder has the characteristics of high conveying efficiency, safe and reliable work, simple structure, complete functions, good sealing performance, low noise, attractive appearance and the like, and is widely used. When facing high-humidity materials or materials with high oil content, the roller type feeder is serious in material adhesion and extremely easy to adhere to the surface of a feeding roller, so that the roller type feeder is blocked, the efficiency is reduced, and the yield of the pulverizer is further affected. At present, the conventional feeding roller cleaning mode comprises the steps of manually scraping a shovel or flushing by using a high-pressure air gun after stopping. The conventional cleaning mode has the defects that 1, the cleaning efficiency is low, the single cleaning time is long, the cleaning is not timely and the risk of material residual pollution is caused, 2, production line equipment is stopped and maintained due to manual intervention cleaning, the production is affected, the cost is high, and 3, the cleaning is not thorough, so that the sticky materials are mildewed and the cross pollution of subsequent batches is caused. Disclosure of utility model In view of the above-mentioned drawbacks of the prior art, the present utility model is directed to a self-cleaning feeder, which is used for solving the problems of high shutdown cleaning frequency, high manual maintenance cost and cross contamination risk of the feeder caused by material adhesion in the prior art. To achieve the above and other related objects, the present utility model provides a self-cleaning feeder, including a box, a feeding roller and a pneumatic cleaning system, wherein the feeding roller is disposed in the box, the pneumatic cleaning system is disposed on the box, the pneumatic cleaning system includes a distributing pipe and a plurality of blowing pipes, the distributing pipe is connected with compressed air through an air pipe, the distributing pipe is arranged in parallel with the feeding roller, the plurality of blowing pipes are uniformly spaced on the distributing pipe and are communicated with the distributing pipe, the bottom end of the blowing pipe is provided with a nozzle, and the blowing pipe stretches the nozzle into the box and is opposite to the feeding roller. In an embodiment of the utility model, the pneumatic cleaning system is disposed obliquely above the feed roller and the blowing pipe is disposed obliquely downward. In one embodiment of the present utility model, a plurality of blowing pipes are arranged in parallel and located in the same plane. In an embodiment of the present utility model, a cover plate is disposed on the top of the case, and an opening for inserting the blowing pipe is formed in the cover plate. In an embodiment of the present utility model, the top end of the blowing pipe is detachably connected to the distributing pipe through a movable joint. In an embodiment of the utility model, the distribution pipe is detachably connected with the air pipe through a quick-release connector. In an embodiment of the present utility model, the air pipe is connected with a solenoid valve and a filtering pressure reducing valve, and the solenoid valve is electrically connected with the PLC control system.
