A rice multifunctional impurity removal device

Abstract

The invention belongs to the technical field of efficient rice impurity removal, and particularly relates to a multifunctional rice impurity removal device. The multifunctional rice impurity removal device comprises a separating tank, a feeding pipe is arranged at the top of the separating tank, a rotating shaft is arranged at the bottom of the separating tank, a plurality of stirring blades are evenly distributed on the rotating shaft in the radial direction, a water inlet pipe is arranged on one side of the bottom end of the separating tank, and a discharging pipe is arranged at the bottom of the separating tank; a liquid outlet pipe is arranged on the separating tank, the other end of the liquid outlet pipe is led into the bottom of an impurity tank, a water outlet pipe is arranged above the impurity tank, and a coarse material outlet capable of being controlled to be opened and closed is formed in the bottom of the impurity tank; and the discharging pipe is communicated with a separating cavity, a packing auger rotating shaft is arranged in the separating cavity, a packing auger is arranged outside the packing auger rotating shaft, a hairbrush is arranged on the outer side of the packing auger, and a heating device is arranged at the top of the separating cavity. The hairbrush is arranged on the packing auger, accumulation of mixed materials in the separating cavity can beavoided, rice abrasion can be avoided, rice grains obtained after impurity removal and drying are guided out through a discharging groove, the overall device is simple in operation, and the rice impurity removal efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of rice high-efficiency impurity removal, and in particular relates to a rice multifunctional impurity removal device. Background technique [0002] As the population continues to increase, people's demand for food is also increasing. Rice, as the most common crop, also increases its production. During the processing, the rice is mixed with stones and chaff. In the prior art, sieves and airflow are usually used to separate them according to different sizes, but in actual operation, chaff and rice are closely bonded, and they cannot be directly separated through the sieve with airflow, and the screening effect is poor. Repeated screening is required, which affects work efficiency. Therefore, the rice impurity removal device needs to be further improved. Contents of the invention [0003] The object of the present invention is to provide a rice multi-functional impurity removal device aiming at the existing...
